Look Around

To become a product developer, you must develop an interest in products. You must learn to look around, to find out how things work, and to find ways of improving them. We begin by walking around the house of one of the authors (JAW), which is nothing special. Here is what you see. 

The toothpaste is like a solid, but liquid when sheared. It stays on a toothbrush as a little white sausage. It contains a large fraction of fine solid particles, as you find out by diluting with water and vinegar, and letting the mixture settle. The particles (which are mildly abrasive) are smaller than 30 pm. How could you get toothpaste to be effective in the crevices between the teeth where it really is necessary  

The first thing you see in the kitchen is the coffee machine. The coffee is in the cupboard above it, in a vacuum pack of metal foil. It consists of ground

Here you find the pastes. Hazelnut paste is a dispersion of particles in a thick emulsion of two liquids, as is peanut butter. Jam is thickened by natural polymers. Soft cheese, butter and margarine are in the refrigerator these are complicated structures of fat crystals, oil, water and many other components. All these pastes have a yield stress that is low enough to let them be spread by a knife, but not so low that they run off bread. Users do find the cold butter a bit stiff and the jam a bit thin. As a developer you might want to improve these things. Bread - a solid foam - is a surprising structure when looked at it closely. Fresh bread is often too soft to cut easily.

Many similar incidents have occurred when a stirrer or circulating pump stopped. For example, an acidic waste stream in a tank was neutralized with chalk slurry. The operator realized that the liquid going to drain was too acidic. Looking around, he then found that the stirrer had stopped. He switched it on again. The acid and chalk, which had formed two separate layers, reacted violently, and the gas produced blew the bolted lid off the tank. 

These are Just some examples of key areas this is not an exhaustive list. Look around your workplace to identify other risk areas. If any risks apply to your work activities, you will need to do risk assessments to check that you have removed or reduced the risk. 

Eq. (2.16) is not an entirely new result. After this work had been concluded and we were looking around in search of bibliographical material, we came upon a paper by Englert and Schwinger [24] dealing with the introduction of quantum corrections to the Thomas-Fermi statistical atom. These authors attain the same result expressed by eq. (2.16) (for... 

Uncle Gareth doesn t let go until I ve wiped my eyes and blown my nose. Then I look around me. Izzy said you were living in here now. ... 

He took the towels from me—they were threadbare too—and looked around the room. I ve got everything, thanks. ... 

Uncle Gareth looked around and saw me, and I asked my question. 

One boy looks around at our entry, open-mouthed instead in secular surprise. He is nudged to order by a virtuous fellow, but at the clank of spurs the clerks heads turn too. 

But it s your right to try to save it. If you want to. None of the rest of us can, not without you. It s you who would make it possible. He s still far away, but at last he stops and looks around at me, really properly. You re necessary. And this time... This time everyone knows it. ... 

Injection molding is one of the most widespread methods used to make polymer products. A cursory look around our homes, schools, work places or cars suffices to find an abundance of injection molded products. One of the reasons that this conversion method is so popular is that it enables us to create complex shapes in a single fabrication process. 

There are many other pieces of processing software out there, some good, some bad. If you don t have any and you need some, it is worth having a look around to see what is available. In our experience, you tend to get what you pay for and the more expensive software is generally better. However, one of the cheaper packages may do just what you want, in which case you have a bargain Table 14.1 lists some of the more well known packages. 

The OSS men, instead of twiddling their thumbs, decided to look around Heidelberg for traces of money. Someone had told them that where they found Schmitz, there they would find money. Schmitz had come up the hard way from a commercial school in Essen, the iron city, and had risen from bank clerk to staff member of the Kaiser s war machine. He had been a director of Farben s predecessor firm, Badische Anilin und Sodafabrik. Also a director of the Deutsches Reichsbank, he was thought to be the wealthiest banker in Germany. In world affairs he had gained considerable respectability as director of the Bank of International Settlements in Geneva. 

A threat that was not veiled I believed, however, that two things underlay Judge Morris unhappiness—a lack of interest in the subject, and the fear that the trial would never be finished. I recalled getting acquainted with Morris at a luncheon on the first day of the trial. Looking around the once-bomb-smashed ceiling, he d shaken his head and said "We have to worry about the Russians now it wouldn t surprise me if they overran the courtroom before we get through."... 

When lunchtime came, Minskoff and Von Halle called in an attendant and notified him that they would come back in about an hour. Dr. Bockmuehl, ignored by the attendant, was embarrassed. He looked around for the stretcher-bearers. They had picked up the stretcher with the blankets and pillow on it, leaving him sitting in the chair. He hesitated as long as he could without appearing too awkward, and sheepishly got up and left the room under his own power. 

If you cannot find it in this way, look around upon the things that are in the world. Then you will find the All—in—All, which is the attracting force of all metals and minerals derived from salt and sulphur, and twice born of Mercury. More I may not say about All-in— All, since all is comprehended in all.
