Abstract: 927,161. Binary parallel adders. ELECTRIC & MUSICAL INDUSTRIES Ltd. Aug. 12, 1959 [May 15, 1958], No. 15631/58. Class 106 (1). In an accumulator in which binary parallel addition is carried out in a number of stages each comprising three magnetic cores C14-C16 with associated transistor circuitry similar to that described in Specification 886,564, the number store is in two parts, a store 1 for sum without carries and a store 2 for carries, and addition of an addend received at 28-32 is in four parts: (1) addend on 28-32 registered in stages; (2) addition of augend from store 1 to give a new sum without carry and a set of carries and addition of these carries to old carries from store 2; (3) adding in of the carry sum from (2) to the sum to give a resultant sum and a further set of unpropagated carries; and finally (4) these numbers are then returned to stores 1 and 2. The selection of rows in stores 1 and 2 is effected by signals at 34 to selector 33, and read-out pulses on one of the lines 3b, 4b, . . . reset any set cores in the stores to provide inputs to the corresponding stages. The new sum and carry are written back by half-strength set pulses in the column lines and lines such as 3a, 4a, &c. An accumulator stage is shown in Fig. 3 (see also Fig. 1 of Specification 886,564 for a fuller description). Shift pulses which reset all cores are applied at 118; any input pulse received via TR1, or a transfer pulse from TR2, is " stretched " beyond the end of the shift pulse by CR network 105, 106 or 126, 129. Core C15 is an entry core which is normally set by an input (addend) pulse (winding 112); at the next shift pulse C15 is reset, and C14 set if there is no (augend) input via TR1, or C16 set if there is such input. Thus C14 then registers the sum bit and C16 the carry bit. If unpropagated carries from 2 due to a previous addition exist, these are received at 25 at the same time as the augend from 1 and entered into cores C16 of the appropriate stages (no carry from the addition of addend and augend can result in these stages since the augend, the sum of the previous addition, must be zero if there has been a carry). The carries in C16 are then propagated by the third shift pulse which resets core C16 and provides an output at 40/O.G. for transmission to input 40/IC of the next stage where it is added to the contents of that stage. The fourth shift pulse reads out the sum and carry bits of each stage on to lines 10 and 16 for writing into stores 1 and 2 by simultaneous energization of the appropriate row wire such as 3a. The timing of the energization of the row wires is effected by a computer programme unit under control of a flip-flop (not shown) which normally operates a four-shift-pulse cycle, but if no carries are stored in the selected line of store 2 then a threeshift pulse cycle takes place, the step (3) above being omitted. Specification 876,912 also is referred to.

Abstract: 752,406. Casting composite articles. GENERAL ELECTRIC CO. May 28, 1954 [May 28, 1953], No. 15886/54. Class 83 (1). In making an electric rotor with cast-in windings, the laminated core is supported in a mould jacket of deformable heat-resistant material, e.g. silicone rubber, matted asbestos, or glass, to which external pressure is applied to cause it partially to enter the winding slots in the core. The laminated core 10 on an arbor 11 is supported between end members 15, 17 between which is also supported the deformable jacket 13 backed by arcuate metallic members 22. The arcuate members are forced inwardly as the end members are drawn together by bolts 21, to thereby force material of the jacket 13 partially into the slots 12. The cast winding will not therefore extend to the periphery of the laminations and finishing operations may be performed without forcing the metal of the winding between the laminations. The winding may be insulated from the core by applying insulating varnish or a clay wash to the sides of the slots before casting. The winding may be aluminium or magnesium.

Filed: 1954-05-28
Abstract: <PICT:0751052/IV(a)/1> Tubular films of organic thermoplastic material which have been oriented by stretching are rendered dimensionally stable by inflating a portion of the running film between two sets of pinch rolls, subjecting the inflated portion to radiant heat evenly round its periphery, and maintaining the entrapped gas at constant presure by adjusting the distance between the two sets of pinch rolls.  The treatment may be effected continuously with production or as an after-treatment.  As shown in Fig. 1, a tube of vinylidene chloride copolymer is extruded downwardly into a cooling bath 12, passed through a warm bath 17 and stretched between rollers 19 and 20 all as described in Specification 656,735.  The tube is then passed to rollers 22, the portion between rollers 20 and 22 having air entrapped therein and being subject to radiant heat from a number of axially disposed heating elements 25 enclosed in a cylindrical housing 23.  As the temperature of the entrapped air rises, the position of rollers 22 mounted on movable support 27 is adjusted so as to maintain the pressure, and hence the width of the flattened film 32, constant. In an example, a film tubular film of oriented crystalline vinylidene chloride copolymer 14 in. in diameter is passed at 100 ft/min. through a heating chamber containing 15 1800-watt elements, the distance between rollers 19 and 20 being 12 ft. 6 in., additional supporting rollers (not shown) being provided. The product shows a marked reduction in residual shrinkage.  Other suitable materials include other vinyl polymers and rubber hydrochloride.
