Abstract: 1,138,549. Read only stores. LITTON INDUSTRIES Inc. 14 Nov., 1966 [26 Nov., 1965], No. 51013/66. Heading G4A. A word organized permanent magnetic linear select memory comprises plural magnetic memory cores in plane 10, and word select cores in plane 12; embedded in substrate 88 (Fig. 1). Cores 14, 16, 18, 20 assigned to bits 1, 2, 3, 4 of word 1 are energized by loop 64 from word select core 22, while cores 24, 26, 28, 30; 34, 36, 38, 40, 44, 46, 48, 50 assigned respectively to bits 1, 2, 3, 4 of words 2, 3, 4 are energized by loops 66, 68, 70 from word select cores 32, 42, 52. Bias source 54 energizes word select cores 52, 32, 22, 42 with current IB while bias source 56 energizes word select cores 22, 32 with current I X1 , bias source 58 energizes cores 42, 52 with current I X2 , bias source 60 energizes cores 42, 22 with current I y1 , and bias source 62 energizes cores 32, 52 with current I y2 ; all sensed to oppose the magnetic effect of current I B . Bit sensing lines 90, 92, 94, 96 threading respective columns of 1st, 2nd, 3rd and 4th bit cores in plane 10 are connected to terminal pairs 72, 74; 76, 78; 80, 82; 84, 86; and initially all cores are set to a stable magnetic state, after which selected cores are broken, e.g. through an apertured template, and an intact core stores information representing " 1 " (or " 0 ") while a broken core stores information representing " 0 " (or " 1 "). E.g. in Fig. 1, the stored words Nos. 1, 2, 3, 4 are 1011, 1001, 0101, 0011 in direct (or 0100, 0110, 1010, 1100 in complementary) arithmetic. Each word select core has rectangular BH curve (Fig. 3) with bias field H at 100. Squarewave current pulses I y , I x2  (Fig. 4) generate field increments H y1 , H y2  opposing the bias to increase H from 100 to 112 for one and to 114 for both increments, whereby B increases from 110 to 116 and a current pulse 118 is applied over loop 68 to memory cores 34, 36, 38, 40 which change state so that cores 36, 40 generate pulses 120, 122 on bit sensing lines to terminals 76, 78; 84, 86, while cores 34, 38 generate only noise 124, 126 on the lines to terminals 72, 74; 80, 82. On removal of currents B reverts and a reverse current pulse 128 over loop 68 resets cores 36, 40 to generate reverse pulses 120, 122 on the appropriate bit sensing lines. Additional word select cores 22, 32, 52 and memory core rows 14, 16, 18, 20; 24, 26, 28, 30; 44, 46, 48, 50 corresponding to different words of the memory are similarly operated to pulse corresponding bit sensing lines, which are assigned to predetermined bit numbers looping all cores of the words corresponding thereto.

Abstract: 1359864 Controlling missiles MESSERSCHMITT-BOLKOW-BLOHM GmbH 10 Nov 1971 [10 Nov 1970] 52188/71 Heading B7G [Also in Divisions F1 F3 and G4] A missile comprises a main thrust nozzle 31, Fig. 3, and a plurality of control nozzle groups evenly arranged about the casing, each group consisting of two, three or four nozzles in which the direction of thrust of one nozzle 45b is parallel to the thrust of the main nozzle 31 whilst the direction of thrust of other nozzles 46b or 47b is such as to urge the missile to rotate clockwise or anti-clockwise about its longitudinal axis, each nozzle group including a switch arrangement for determining through which of the control nozzles gas is emitted. The direction of the thrust of the fourth control nozzle (not shown) is opposite to that of the main nozzle 31. The control nozzles, as well as rotating the missile, can also be used to produce torques about the pitch and yaw axes of the missile. Gas for the control nozzles is tapped off by conduits 43a-43d at points intermediate a pro-combustion chamber 28 and a combustion chamber 29. A turbine 30 located between an advance grid 32 and a retardation grid 33 actuates pumps 35 and 36 for conveying propellant components from storage containers 37 and 38, respectively. The propellant component from container 37, before being introduced into the pre-combustion chamber 28, is fed through a conduit used for cooling the combustion chamber 29 and main nozzle 31. Part of the propellant component from container 38 is not fed into the pre-combustion chamber, and, instead, is fed into the retardation grill 33. Electrically operated throttle valves are used for determining through which of the control nozzles 45b, 46b and 47b the gases are emitted. However, where there are only two nozzles 10a and 12a, Fig. 2, in each group, gas from inlet 16 is directed into one of two channels 18a and 18b by the effect of controlling gas flowing from passage 19a or 196. A baffle 20 initially directs flow into passage 18a, but soon melts. (For Figures see next page.)

Abstract: 1351397 Lamp failure alarms; road traffic signals on vehicles ROBERT BOSCH GmbH 28 Nov 1972 [29 Nov 1971] 54861/72 Headings G4N and G4Q A flasher circuit for a vehicle comprises: means 40, 41 for varying the resistance of a circuit containing at least one flasher lamp 37, in dependence on the position of a switch 54 which operates the vehicle headlights 52, 53; a pair of control elements, e.g. resistors 55, 56 having a junction 57 which is connected to a switch 59 controlled in dependence on the position of switch 54; and a further switch, e.g. transistor 48 controlled by the control elements and connected to a pilot lamp 51. With headlight switch 54 open, switches 41, 43 are closed shorting resistors 40, 42 and rear turn indicator lamps 37, 39 operate at full brightness when actuated. Switch 59 is also closed, shorting resistor 56, the full lamp current flowing through resistor 55, whenever flasher switch 44 closes, being sufficient to turn on transistor 48 and energize pilot lamp 51. If one of the turn indicator lamps 36 ... 39 fails, the current through resistor 55 is insufficient to turn transistor 48 on, and pilot lamp 51 remains unlit. When switch 54 is closed, switches 41, 43 open to reduce the brightness of the rear turn indicator lamps 37, 39, and thus reducing the current through resistor 55. In order to ensure a sufficient base-emitter voltage to turn on transistor 48, switch 59 opens to switch a further resistor 56 in series with resistor 55. In a modification, Fig. 2 (not shown) the two resistors 55, 56 and transistor 48 are replaced by a relay having two windings, so that the number of turns is increased in the low current condition.

Diffusion apparatus for separating components of gaseous or liquid systems comprises a perforated tube 19 axially located in a bundle of semi permeable hollow fibres 10 optionally looped within a fluid tight jacket 15 so that all their ends embed in and pass through a cast block 12, which closes the jacket, and open at 11 into a chamber 18 defined by the block and an outer cover 28. The bundle of fibres 10 is constrained e.g. by a porous sleeve, by intermittent bandings or by the jacket itself. In operation fluid under pressure flows from inlet 16 to the furthermost end of the jacket 15 and also radially across the fibres toward perforations 21 &c. Fluid which permeates into the fibres is withdrawn through a port 20 via the chamber 18 whilst the non-permeating component is withdrawn at port 17 via the perforations. The flow in this case is countercurrent but the inlet port 16 can be positioned so that it is concurrent or half and half. The perforated tube may additionally or only pass through the cast block 12 and exit through a second port in the chamber 18. In a modification two relatively rotatable concentric perforated tubes are used. In another modification, Fig. 12 (not shown), the jacket and outer cover contain several bundles of fibres each passing through their own cast blocks into a common "permeate take off" chamber. Many applications of the apparatus are given, e.g. the separation of hydrogen and hydrocarbons, desalination of water.
