Title: Cheese-making curds wringing press - has drives from shaft moving ram up and down and indexing it
IPC: A01J25/11
Filed: 1976-10-29
Abstract: The curds wringing press partic. for cheese making on farms has a semi-cylindrical ram movable up and down and which also can be rotated in a horizontal plane. From a continuously rotating drive shaft a drive is taken to the ram to impart to it an up-and-down movement, while a second drive indexes it through an angle when near the uppermost position. this allows the press to operate automatically from a power source such as a motor with reduction gear. The reciprocating and indexing drives can be taken to a number of presses at a time, the stroke of each press being adaptable to suit the amount of curds in the vessel in which it works, while maintaining constant pressure on the curds.

IPC: C07D295/088
Filed: 1977-02-24
Abstract: Carene derivs. of formula R-CH2O-(CH2)n-NR1R2 (I) and their acid addition and quat. ammonium salts are new. In (I) R = a carene residue, R1 and R2 = H, 1-4C alkyl, or NR1R2 form a 5- or 6-membered heterocycle which may contain another hetero atom, n = 1-4. A claimed cpd. is 1-(N-diethylamino)-2-(2-arene-4-yl methoxy) ethane, b.pt. 106 degree C/1 mm. In an example, this was prepd. by treating DELTA 3-carene with paraformaldehyde in the presence of acetic anhydride, formic acid and phosphoric acid, to give 2-carene-4-yl methanol. Treatment with sodium gave the alkoxide and reaction with 1-(N-di-ethylamino)-2-chloroethane gave the desired prod.

Title: Regenerating catalyst from hydrocarbon cracking - by oxidn. in fluidise beds with gas successively in parallel flow and in cross flow, minimising residual coke
IPC: B01J8/26
Filed: 1978-02-16
Abstract: Regenerating, by oxidn. a used catalyst from hydrocarbon cracking, comprises carbonisation of the coke deposits in two phases during the passage of a regenerating gas through a fluidised bed of the catalyst, in an appts. comprising a body in the tower part of which is mounted a cylinder forming with the body of an annular space. The cylinder is provided with a pipe for charging used catalyst. A column for discharging regenerated catalyst is placed in the annular space. The cylinder and the annular space are equipped with their own pipes and distributors for charging regenerating gas. A cyclone separator and a used gas outlet pipe are mounted in the upper part of the body. A vertical partition is mounted in the annular space.
