[Also in Division E1] Rigid foamed resin elements, suitable for use in the building industry, include continuous parallel filaments extending longitudinally of the elements. The filaments may be uniformly distributed throughout the cross-section or may have a higher concentration in the regions of higher stress. The foam may be of polyurethane; phenol, urea or melamine formaldehyde; polyester; polyolefine; polyamide; polystyrene; or an epoxy resin. The foam may be made from a reactive liquid precursor, a liquid precursor into which voids have been whipped, fibres which may be converted into foam or already foamed hollow fibres and the filaments may be of glass, rayon carbon, polyamide, polyester, or polyolefine. The precursor may be added to the filaments prior to or during shaping in a mould. In the described embodiment, filament rovings are drawn through a precursor bath, through a die and are wound into a circular hank on a rotating disc provided with spaced pegs. The hank is subsequently removed, reshaped into a long straight configuration, and placed in a P.V.C. lined mould (see Fig. 2, not shown), the foaming and hardening of the resin then being effected.

Title: Time lag relay with a short recovery time
IPC: H03K17/292
Filed: 1973-11-09
Abstract: 1391748 Transistor relay circuits ALLMANNA SVENSKA ELEKTRISKA AB 9 Nov 1973 [10 Nov 1972] 52070/73 Heading H3T The capacitor C1 of a time relay delay is rapidly discharged (by P.U.T. 3) to prevent erroneous relay operation in the event of voltage supply 9 interruption. C1 is normally charged through a fast charge circuit R2, R3, R4, V4 up to a certain level, and then through the slower circuit R1. A P.U.T. V2 has its trigger voltage set by a potentiometer R7, R8 and turns on bi-stable transistors V9, V10 when C1 has charged enough, to operate the relay 11. If the voltage supply 9 should fail, a capacitor C3 holds gate 7 of V2 above its anode to prevent relay operation; V3 however, whose gate 4 is normally held much higher by V5, V6, R5 than gate 7 of V2 so that it normally never turns on, now conducts due to the rapid fall of its gate voltage caused by the voltage supply failure. C1 is thus discharged through V3 ready for another complete cycle when the voltage supply 9 is restored. V3 compensates V4; C2, C5 limit interference.

Title: Angular Modulation Receiver.
IPC: H03D3/24
Filed: 1967-11-16
Abstract: 1,199,467. Frequency modulation receivers. INTERNATIONAL STANDARD ELECTRIC CORP. 16 Nov., 1967 [18 Nov., 1966], No. 52140/67. Heading H3R. The signal-to-noise ratio of a FM receiver is improved by demodulating with a locked-in oscillator 1 and using this oscillator to provide negative feedback and thereby reduce the frequency deviation of the I.F. signal. In the receiver illustrated the oscillator 1 is locked to the I.F. signal by means of a phase detector 3 and a narrow-band filter 5, and supplies the local oscillations to the mixer 7 via a frequency multiplier 8. If X is the multiplication factor of the multiplier, the compression factor is also X and the relation between the RF frequency fRF and the I.F. frequency f IF  is f RF  = (XŒ1)f IF . If a reference frequency fRef from source 10 is supplied to the mixer, the equation becomes f RF  = (XŒ1) f IF Œf Ref , which allows more choice of parameters. The output signals may be derived from filter 5 but are preferably derived from oscillator 1 via limiter discriminator 14.

Filed: 1971-11-18
Abstract: 1317516 Starting prime movers GENERAL MOTORS CORP 18 Nov 1971 [23 Nov 1970] 53550/71 Heading H2H An electric starter motor automatic disconnect and lockout circuit comprises means to disconnect a starter motor for an internal combustion engine from a D.C. supply source when the engine has started, and to prevent inadvertent activation of the motor when the engine is running. As shown, an engine 4 is cranked by a starter motor 3 supplied by a battery 2 via the normally open contacts 17, 18 operated by coils 18, 19. In operation, a manual switch 35 is operated to the "start" position to close contacts 37, 38 with the positive battery terminal. S.C.R. 30 is triggered into conduction via resistor 59 and diode 63 to apply a base current at 11 to transistor 10 through resistance 55 to switch this component on and pass current through coil 26 of relay 25 to close contact 27 to pass current through both coils 19, 16 to close contact 17 and enable the starter motor 3, the coil 19 holding the contact in after coil 16 is shorted by the closure. A generator 56 is attached to the motor 3 to be rotated thereby and upon the engine 4 starting, a voltage proportional to its rotational speed is produced across the gate and cathode of a second S.C.R. 40 in parallel with the base and emitter of transistor 10. After a certain speed is attained, thyristor 40 conducts and shunts out the base current of transistor 10, turning the latter off and de-energizing coil 26 of relay 25 to open contact 27 and de-energize the motor 3 via contact 17. This situation continues until switch 35 is moved to its "run" position to connect terminals 38, 39 to the battery 2. A vibration transducer 75 mounted on the engine 4 delivers an A.C. signal to a current amplifier 50, 60 which is modified at 70 to a series of square pulses which are applied across the baseemitter of transistor 20 to render this conductive if a potential is applied thereacross. If the switch 35 is moved back to the "start" position whilst the engine is running, triggering of S.C.R. 30 is prevented by the transistor 20 which shunts the trigger current.
