Ploughing

The plough cannot be allowed to reach too close to the cloth and some residual cake remains. Where this is not acceptable, the cake may be removed by a pneumatic system, by vacuum, or by reslurrying. The cycle can be automated and controlled by timers. The maximum speeds of basket centrifuges vary from 800 to 1500 rpm, and basket diameters are in the range from 10 to 1400 mm. A 1200-mm diameter, 750-mm long basket may handle as much as 200 kg of cake in one charge.

Total sales of prescription bronchodHators and antiasthma products in 1989 were approximately 1.2 and 3.3 bHHon in the North American and world markets, respectively (166). The three largest shares of the world market were held by Glaxo Holdings pic, Schering-Plough Corporation, and Boehringer Ingelheim Corporation. 

Florfenicol (2) has been approved in Japan for the treatment of pseudo-tuberculosis caused by Pasteurellapiscicida and streptococcosis m. yeUowtail fish. The recommended dose is 10 mg/kg for up to one week and the drug withdrawal time is five days after cessation of treatment. Florfenicol is active in bovine respiratory disease caused by Pasteurella species and mastitis caused by Staphylococci and Streptococci. It is also effective in neonatal cohbacillosis caused by E. coli. The drug is being developed worldwide by Schering-Plough Animal Health for the treatment of aquatic and bovine diseases.

One of the relationships iised to obtain Figure 7 was that between the amount of organic nitrogen in the soil, kg ha and the time, t yr, from the ploughing out of the permanent grassland. This was an exponential relationship derived by fitting to field data. ...

Ploughing of sugar crystals at very low speeds of 50 r.p.m. or so. This is achieved by a 48- or a 56-pole motor. A further reduction in speed is obtained by conventional electrodynamic or d.c. electric braking. 

Obviously, the rate of abrasive wear can be reduced by reducing the load - just as in a hardness test. The particle will dig less deeply into the metal, and plough a smaller...
