Title: Improvements in radio direction finders
IPC: G01S3/08
Filed: 1934-11-26
Abstract: 452,651. Directive wireless signalling. KRUESI, G. G., 638, Plymouth Avenue, Dayton, Ohio, U.S.A. Nov. 26, 1934, No. 33979. Convention date, Nov. 25, 1933. [Class 40 (v)] A radio compass designed to give a clear-cut cardioid curve is characterized by a particular coupling between the vertical and frame aerials and the common collector circuit. The vertical aerial is not resistance-phased, but is untuned so that the signal is materially out of phase with the voltage, whilst the frame aerial is tunable. Each aerial is individually coupled to the collector circuit by a fixed coupling, which is greater than that between the two aerials. The coupling between the two aerials must be sufficiently small to permit the relation between current and voltage in the tunable circuit to be varied, without affecting the phase relation in the vertical aerial. A variable reactance in the frame aerial circuit is then used to bring the current induced by it in the collector circuit into phase alignment with the current separately induced by the vertical aerial. The Figure shows the invention applied to a direction finding system of the kind described in U.S.A. Specification 1,868,945, in which the signals received by the vertical and frame aerials are combined and reversed, by means of a balanced modulator, in such a way that the resultant current deflects an indicator through an angle proportional to the deviation of a moving craft from the " homing " line. The coil 78 of the vertical aerial 48 is coupled to the grids of the two modulator valves 86, 88, which are energized from a local oscillator 203. The output from the two valves is coupled through the coils LP<1> and LP<2> to the coil LR of the collector circuit. The frame aerial 10 is also coupled to LR by the coil LL, and is balanced to earth at 210, 211. The number of turns and relative positions of the coupling inductances are so selected as to comply with the conditions first mentioned. The coil LR is grounded at 80, and to avoid an unbalance due to the ground capacity, a screen 82 is interposed between the coupling coils and is grounded at the opposite end 84. Variable condensers C<1>, C<2> are also inserted in each branch of the plate circuit to compensate for any unbalance between the characteristics of the valves 86, 88. The required phasing of the loop circuit is secured by means of a variable condenser 26 which is ganged with the main tuning condenser 30 of the receiver to a control knob 34. The low-frequency transformer 106 connecting the output from the modulator to the receiver is inserted, as shown, in the cathode circuit of the valves to isolate it from the aerial 48 and prevent undesirable reaction. It is connected through a junction box 60 to the " bearings " indicator 40, which is branched across a bridge circuit 207. A contact 92 allows the receiver to be switched over from the " compass " position to feed a pair of phones 64 in order to enable the call signals of the beacon station to be identified.

Filed: 1973-07-19
Abstract: 1405977 Transistor logic circuits CHRYSLER CORP 19 July 1973 [31 July 1972] 34407/73 Heading H3T [Also in Division B7] A device for warning vehicle occupants of the improper use of seat belts comprises a belt actuated switch, a seat switch and a logic sequence means which is responsive to a predetermined order of actuation of the switches and which activates an alarm if the sequence is violated. Each occupant position has a seat switch 10, 12, 14 and a safety belt fitted with a switch 11, 13, 15 actuated by use of the belt. On actuation logic circuit 18 determines if the seat switch is actuated before the belt switch and triggers a warning control if this sequence is violated or if either switch is not actuated. A filter and time delay means 16 allows for brief deactuation of the seat switch, e.g. during occupant movement, by desensitizing the logic circuit without the alarm being actuated. The logic means 18 is also connected to a start control 30 which locks the ignition system if the predetermined sequence is violated to prevent starting. A restart timing mechanism 46 is connected to the starting control to allow the vehicle to be restarted once it has been started and the ignition has not been turned off regardless of the seat belt usage, or to allow restarting of the vehicle for a period of approximately three minutes immediately after the ignition switch is turned off once the vehicle has been previously started.

Title: Improvements in electromagnetic relays and the like
IPC: H01H47/12
Filed: 1921-12-22
Abstract: 195,152. Western Electric Co., Ltd., (Western Electric Co., Inc.). Dec. 22, 1921. Electromagnetic switches; alternating-current relays.-A relay adapted to operate as a polarized relay or an alternating-current relay comprises a pair of E-shaped electromagnets with an armature between them. The electromagnets carry a plurality of windings arranged in series to form a closed circuit and the arrangement is such that one magnetic flux is produced in a circuit cutting the armature at right angles and a second in circuits including the armature and in opposite directions in adjacent parts of the armature. As shown in Fig. 1, an armature 7 mounted in trunnion bearings is arranged between the poles of the laminated E-shaped cores 1, 2 and is held normally in the mid-position by a spring 8. An insulated pin 9 presses contact springs 10, 11 or 12, 13 together according to the direction of movement of the armature. The relay is shown in Fig. 2 connected for operation as a polarized relay by impulses coming in over the line 16, 17. The polarizing source 15 produces a flux shown in continuous lines in Fig. 1, the direction of which varies with the direction of the impulses. This results in the flux in one of the cores being neutralized and in the other strengthened so that the armature moves over. For operation as an alternating-current relay the source 15 is replaced by a source of alternating current, such as the transformer 20, Fig. 4, of the same frequency as, and in phase with the operating current.

Title: Improvements in or relating to receivers for remote control systems
IPC: H02J13/00
Filed: 1960-10-10
Abstract: 892,662. Electric selective-signalling systems. COMPAGNIE DES COMPTEURS. Oct. 10, 1960 [Oct. 9, 1959; Dec. 1, 1959], No. 34609/60. Class 40 (1). In a signalling system of the type in which a start pulse is followed by one or more differentially-timed executron pulses a receiver is provided which will only respond to executron pulses accurately timed in relation to the start pulse. Further, the periods between a start pulse and an executron pulse and between any two executron pulses are such that no executron pulse can function as a start pulse. As described, a start pulse causes one revolution of a shaft 3, Fig. 1, by causing a lever 24 to close contacts 29 which are then kept closed for the remainder of the cycle by a cam 31. As the shaft 3 rotates, a lever 5, on a fixed pivot 6, follows the teeth on a cam 30 under the action of a spring 7. Any executron pulse, if it is correctly timed, has to arrive when the lever 5 is on the crest of one of the teeth on the cam 30 (i.e. when the spring 7 is tensioned at its maximum) and if it so arrives it causes a member 34 to be moved into the path of an arm 33 to thereby actuate a switch, not shown. Each start or executron pulse received causes a vibrating reed 52 to rotate a shaft 56 via a friction disc 53, gears 82 and coupling 55. Providing the pulse is received when lever 5 is on a crest on cam 30 a cam 57, on the shaft 56, then releases and lowers a lever 64 thereby releasing a lever 70 and permitting a member 20, on a shaft 21, to rotate in the direction of an arrow F2 under the action of spring 7. This rotates the shaft 21 thereby moving the member 34 into the path of the arm 33. The member 20 also closes contacts 29. If a pulse arrives whenlever 5 is not on a crest of cam 30, a member 11 is positioned with its lip over a projection on cam 57 thereby preventing it releasing lever 64. At the end of a pulse shaft 56 returns to its normal position under the action of a spring 63 and the member 20 and lever 70 return to their normal positions under the action of a spring 35 when the lever 5 enters a valley in the teeth on the cam 32.

Abstract: 973,350. Artificial respiration training dolls. A. LAERDAL. Sept. 29, 1961, No. 35044/61. Heading A5T. A training doll for training in mouth-tomouth resuscitation has a mouth or nose opening connecting with a lung bag by a duct having a valve 8 which permits air blown into the opening passing to the lung bag but which prevents air leaving the lung bag returning to the opening and diverts it to atmosphere. The doll includes a neck portion 5 having an upwardly directed pipe 2 which connects with a flexible pipe 1 to the mouth or nose opening (not shown). The neck portion is fitted to a shoulder portion 6 having a pipe 3 which connects with the pipe 2. A channel 25, formed between the shoulder portion and a part 4, connects the pipe 3 with the lung bag (not shown) and a duct 7 connects the pipe 3 just above its lower end with atmosphere. The valve consisting of a hollow cylindrical body 8 having a slot 8<SP>2</SP> at its lower end is located in the pipe 3 with its upper end fixed and normally closes the duct 7. When air is blown into the mouth or nose opening, the slot 8<SP>2</SP> opens to permit passage of air into the lung bag. Air leaving the lung bag has no opening effect on the slot and longitudinally compresses the cylindrical valve body 8 so that the inner end of the duet 7 is opened to vent the air to atmosphere at the rear side of the shoulder portion. An alternative form of valve body (Figs. 5 and 6, not shown) comprises a pipe having a duct interconnecting its upper and lower ends located above a duct connecting the lower end of the pipe with the exhaust duct 7. A plug is moved into the lower duct to block the exhaust duct when air is blown into the mouth of the doll and is moved by air leaving the lung bag into the upper duct to connect the lung bag to atmosphere through the exhaust duct.
