Title: Electronic data processing apparatus
IPC: H04L12/52
Filed: 1971-08-17
Abstract: 1393898 Data transmission [SYSTEMWARE Ltd 16 Aug 1972 [17 Aug 1971] 38432/71 Heading G4A A data processing apparatus receiving data from one of a plurality of incoming lines, performing one or more processing functions and then forwarding the data to any one of a plurality of outgoing lines has a multiplexing means 8 selecting signals from any one of input lines 4 and feeding them to a function unit 14 and thereafter through a demultiplexer unit 20 on to any selected one of outgoing lines 5. This provides a direct switching between any incoming lines and any outgoing either directly, or after performing a processing function. To this end incoming signals may additionally or alternatively be fed to a multiplexer 36 supplying the second input to a function unit 14 which may operate in conjunction with an arithmetic unit 50 performing particular calculations. Input lines 4 are connected through level changing amplifiers 6 to multiplexer 8 having output line 10 connectible to an input line and a group of 16 output lines 11 connectable to any one of four sequential groups of input lines, each under the control of signals received on line 12. Function unit 14 may perform a number of operations and its output may connect to any one of 64 output lines 22 through demultiplexer 20, receiving also a group 25 of 16 lines connectable to any sequential group of 4; through register 26 having a stage for each line, signals may pass through level changing amplifier 28 to a corresponding output line. Channel 22 is also connected to register 30, similar to 26 connected by 64 lines to multiplexer 36 which may feed together with multiplexer 8, a 16-bit arithmetic unit 50. In such mode, data selected by 8 passes through 14, 20, 30, 36, 50 to function unit 14 and whilst data is being circulated through this circuit a second item of data may be inserted into 14 and an arithemtical operation performed thereon, the result being fed out through 20, 26 &c. In another mode store 48 can convert into serial form for transmission on the single output line, data received in parallel on a group of input lines. Conversely parallel/serial conversion may be effected. A number of other shunting and calculational functions may be performed by the apparatus, examples of which are mentioned in the specification.

IPC: C01B7/13
Filed: 1970-08-11
Abstract: 1276445 Copolymers of vinylpyridines YEDA RESEARCH & DEVELOPMENT CO Ltd 11 Aug 1970 [28 Aug 1969] 38645/70 Heading C3P The invention comprises copolymers of (a) 1,3,5-triacryloylhexahydro-1,3,5-triazine and (b) a vinyl pyridine or alkyl-substituted vinyl pyridine, preferably containing 2-5 to 15 wt. per cent of (a). The cross-linked polymers form complexes with halogens, especially Br 2  and I 2 , and can therefore be used to remove these from a medium containing them. Alternatively the complexes can be used as a supply of pure halogen since they are decomposed e.g. by organic solvents or by reduction. The copolymers can also be quaternized at the pyridine nitrogen atoms to give anion exchange resins. The examples describe the preparation by conventional methods of suspension or bulk polymerization of copolymers based on 2- or 4-vinylpyridine or 2- methyl-5-vinylpyridine or mixtures of these.

[Also in Groups XII and XVIII] A die-casting machine comprises a pot for molten metal, a goose-neck and pump assemblage which is pivotally mounted to allow the goose-neck to engage and disengage the dies, and means for maintaining a predetermined level in the pot, and inert gas above said level, and which includes an automatic feed mechanism arranged to maintain an ingot of metal in and above an aperture in the top wall of the pot and to feed the ingot into the pot to replenish the supply of metal in the pot. In one embodiment for casing magnesium, Figs. 1 and 1a, the melting-pot 10 and the goose-neck assembly are pivoted on a pivot 22, and move as a whole to disengage the nozzle 17 from the dies 18, 19. The pot is fed by an ingot 32 suspended on a chain 36. The downward movement of the ingot, due to gravity, is stopped by a brake 54 actuated through a solenoid 57, when the level 26 rises to its predetermined position, a float 65 thereupon closing a switch 60 in the solenoid circuit. Blades 49 on a gear-wheel 48 which rotates at high speed during the downward movement of the ingot, act as a governor device. In a modification, the goose-neck and pump assembly is pivoted for movement, the pot remaining stationary.
