Abstract: 1,181,248. Magnetic storage apparatus; transistor circuits. INTERNATIONAL BUSINESS MACHINES CORP. 2 Aug., 1967 [4 Aug., 1966], No. 35405/67. Headings H3B, H3T. [Also in Division H1] In a magnetic thin film memory device in which a V.H.F. signal is applied to the film to read out information stored therein a sense line is coupled to a phase detector to detect differences in phase between the V.H.F. signal and the signal induced in the sense wire during read out. The memory matrix of Fig. 5 comprises a plurality of word drive lines 14 arranged parallel to the easy axis, each drive line being enclosed by a closed hard loop anisotropic thin film member 2 of generally trapezoidal crosssection, Fig. 1 (not shown). In order to read out information stored in the matrix determined by the direction of the magnetization vectors along the easy axis a V.H.F. source 32 provides a V.H.F. signal to a plurality of V.H.F. gates 122-125, one of which is selected by the matrix type gate select circuit 126 so that a V.H.F. signal is applied to the selected word drive line 14. This results in a reduction of the strength of the magnetic state of each bit and a corresponding resultant E.M.F. is generated in the bit sense lines 28 which E.M.F. is advanced 90 degrees out of phase from the signal on the drive line 14 if a " 1 " is stored in the bit and is retarded 90 degrees out of phase from the signal on the drive line 14 if a " 0 " is stored. In order to detect the difference in phase, phase sensitive detectors 136, Fig. 3 (not shown), are connected to the sense lines 28, each phase detector comprising a transistor to the base of which is connected the sense line and to the emitter of which is connected via an R.C. network the V.H.F. signal, the output at the collector of the transistor being a maximum for one binary value and a minimum for the other. The V.H.F. source 32 may be connected to two opposite conductivity type transistors 34, 36 which are alternately switched on to deliver positive and negative spikes of voltage to an LC parallel circuit at twice the frequency of the V.H.F. source, Fig. 2. Fig. 4 shows one of the gates 122-125. In operation both diodes 110, 108 are normally back biased so that no V.H.F. signal applied to terminal 106 reaches output 102. A gate signal switches transistors 90 on and so forward biases diodes 110, 108. The gate signal is summed with the output of the V.H.F. line by resistor 98 to prevent a pedestal from being superimposed on the V.H.F. signal.

Abstract: 1,028,093. Direction indicator switches for road vehicles. FORD MOTOR CO. Ltd. July 22, 1964 [Sept. 10, 1963], No. 35581/63. Heading G4Q. A turn indicator switch comprises an annular switch arm 7 which can be pivoted about an axis B by means of a manual arm (not shown in Fig. 1), and a return member 10 which is rotatable about a base member 1 by the steering wheel. The switch arm is held in one of its three positions by the engagement of a roller on the switch arm with one of three recesses 51, 51<1> or 53 in a resilient element 47 attached to the base 1, and lugs 21 on the switch arm cause a plastic moulding 9 to rotate with it. When the switch arm is displaced from its central position, one of two webs 67 or 69 on the moulding 9 extends into the path of projections 63 and 63<1> on the return member 10. When the member 10 is rotated in the same direction as the switch arm, the projection 63 meets a wall 71 of the web which is so inclined as to allow the web to be deflected, but when the member is rotated in the opposite direction after making the turn, the projection 63 meets a wall 711 of the web which is so inclined that the moulding behaves as a rigid member and the switch arm is returned to its central position. If, however, the manual arm is held in position, the projection 63 can ride over the web and the switch setting is not affected. A tag washer at the end of the steering column may be provided with an extension located in one of the indentations 63 in the member 10 so that the latter rotates with the steering wheel.

Vehicle heating and ventilating apparatus comprises two fresh air flow passages communicating with the vehicle interior, one of the passages containing a heat exchanger fed with engine coolant and having a damper controlled opening leading to the exterior of the vehicle, the damper and further damper controlling air flow through the passages being arranged so that air flows through the heat exchanger at all times. As illustrated in Fig. 3a, the two passages 13 and 14 are fed with air by a fan and air flow from the passage 13 containing the heat exchanger 10 to the exterior of the vehicle is controlled by a flap 20 spring biased to a position shutting off the air flow. A flap 17 controls the proportions of air passing from passages 13 and 14 to a mixing chamber 22 and a flap 27 either shuts off flow to the vehicle interior, or allows flow to windscreen ducts 26 or allows flow to these ducts and through an opening 4 to the passenger space. The flaps 17 and 27 are operated by separate controls and are linked to strikers 38 and 39 which both, in the Fig. 3a position, hold the damper 20 open against its spring bias. Movement of both flaps away from their Fig. 3a positions allows the flap 20 to move towards its closed position. In another embodiment, Figs. 5-7, a flap 70 proportions hot air flow between the vehicle exterior and interior and a flap 71 controls air flow through the cold air passage 67. Air flows to the windscreen through openings 84 and air flow to the passenger space through openings 83 is controlled by a flap 72. Flap 72 is fixed to a link 101 (Fig. 7) connected to a cam follower 106 which is spring-biased against a cam member 98. Flap 70 is fixed to a link 92 connected to a link 94 pivoted at 95 which has a follower 97 engaging a cam track 96 in the member 98. The cam member is operated by a cable 90 between one extreme position in which flap 71 is closed and flap 70 directs hot air entirely to the vehicle exterior, and another extreme position in which flap 71 is closed and flap 70 prevents air flow to the exterior. The engine block 50 (Fig. 5) is connected to the air heating heat exchanger 51 via a valve 56 having a controlling wax capsule 57 which permits coolant to flow to a radiator 58 when the coolant. temperature exceeds 80 degrees. The fresh air fan 62 is energized by a manual switch 63 and by a switch 64 sensitive to coolant temperature which operates at 90 degrees to cause the fan 62 to run at greater speed than is attained by manual control.
