Patent GB-969572-A (GB)
Title: An arithmetic unit for a digital computer
IPC: G06F7/48
Filed: 1962-09-12
Abstract: 969,572. Computors; microprogramming. TELEFUNKEN PATENTVERWERTUNGSGESELLSCHAFT. Sept.12, 1962 [Sept. 13,1961], No. 34824/62. Heading G4A. In a computor in which arithmetic and other operations are performed as subroutines comprising micro-operations, the arithmetic unit comprises at least two registers A, B, which are connected together for the performance of micro-operations, and has an additional register V, which by its setting can control the orders of registers A and B in which the micro-operation can be performed. Thus, Fig. 1 shows the connections between the bi-stable circuits 1,2 of register A and 3,4 of register B in order that the operation: transfer B to A, can be performed. The command pulse S11 for the operation is received on line 5 but the transfer of a one bit from circuit 4 to circuit 2 can only take place if the left-hand side of circuit 11 of register V is up so that all inputs to the and circuit formed by diodes 7 to 9 and 12 and resistor 6 are up. Fig. 2 shows the connections for the micro-operation: invert register A. There are two additional control lines 20, 21. Here, when the invert command S8 is received, circuit 2 will only change its state if both the left-hand side of circuit 11 and line 20, or both the right-hand side of circuit 11 and line 21 are up. If both lines 20 and 21 are up the micro-operation will take place unconditionally. The Specification describes with respect to Figs. 3 to 6 the construction of an arithmetic unit in which micro-operations are performed conditional on the pulsing of either specific ones or both of a pair of condition lines, like the lines 20, 21 of Fig. 2. The invention may be realized in either a parallel mode or serial mode unit. In the latter case the registers could be shift registers.
Patent GB-1066880-A (GB)
Title: Methods of and arrangements for the continuous hydrogenation of oils and fats
Inventor: KEHSE WOLFGANG
IPC: C11C3/12
Filed: 1965-08-14
Abstract: Oils and fats are continuously hydrogenated by a process in which dispersed catalyst is added to oil to be treated and the oil-catalyst mixture is passed successively over a plurality of perforated plates arranged on top of each other in a column, the mixture travelling across each plate along a path defined by partitions, hydrogen being circulated in excess upwardly through the column by means of the perforations in the plates, optionally in admixture with an inert gas, to maintain the oil on the plates. Used catalyst suspended in oil is usually added to the oil supplied to the uppermost plate, and fresh catalyst suspended in oil may be added to the oil at a subsequent plate.  The hydrogen is supplied from an electrolytic cell and is recircled after use, the amount of fresh hydrogen needed to add to that recircled in order to provide a constant pressure in the column being produced as necessary and determined by control means, so that no hydrogen storage facilities are needed.  Both fresh and recircled hydrogen are dried, and the reaction heat may be removed by cooling pipes fitted round the outside of the column.

Heading F1P, A fluid pressure operated actuator comprises a cylinder 1 having a double-acting piston 7 therein formed with a ring of radial recesses 8<SP>1</SP>, 9<SP>1</SP> adjacent each end face 8, 9, thereof, in which are slidable segmental locking shoes 13<SP>1</SP> which in their radially retracted position allow the piston to move, and in their radially extended position engage with the rims 25, 25<SP>1</SP> of the cylinder 1 to thereby lock the piston in either its extended or retracted position. The locking shoes are automatically radially extended at the ends of each stroke by the engagement of their inner arcuate cam surfaces 27, 27<SP>1</SP> by plungers 18, 19 operating in respective bores 16, 17 in an end cap 5 and a piston rod 10. Unlocking of the piston from its retracted position shown, is effected by supplying fluid pressure through a line 21 to a chamber 16<SP>1</SP> within the piston, whereby the plunger 18 is retracted and the shoes 13<SP>1</SP> coact with the bevelled rim 25 thereby inwardly retracting to allow the piston 7 to move. A lever 28 having a fulcrum 29 may be operated to manually retract the plunger 18. A device mounted at each end of the cylinder 1 for indicating that the piston is locked comprises a spring-loaded bobbin 35 which is depressed by the extended shoes 13 to move a contact 37 to bridge fixed contacts 39.

Non- ferrous powder may be used, such as 60 to 80 per cent copper with the remainder zinc or 90 to 95 per cent copper with the remainder tin. Phosphorus up to 0.3 per cent may be added. Aluminium alloys may also be used. The sintering temperature is from 1700‹ to 1900‹ F. for ferrous powder and 1500‹ to 1650‹ F. for brass or bronze. The sintered insert 20, Fig. 1, is placed in a recess 18 in a tapped nut 10 and secured by flanging over, at 22, an upstanding wall 24. The flange may be indented at spaced points 30 further to secure the insert against rotation. In some cases the insert may be tapped to form an undersize thread that is a continuation of the nut thread. A number of flutes may be formed in the bore of the insert to facilitate the impression of a thread. Inserts may be fitted in castings that are tapped to receive screws without the use of separate nuts.
