Title: Improvements in shock absorbing devices for spring supported vehicles
IPC: F16F7/06
Filed: 1921-01-26
Abstract: 172,574. Dufty, N. E. Jan. 26, 1921. Addition to 168,673. Vibration-dampers.-A modification of the vibration-damper for spring-supported vehicles described in the parent Specification comprises a lever pivotally connected to an axle-tree and to one end of a brake band in such a manner that compression of the vehicle spring causes the lever to allow the ends of the brake band to move apart by relaxing the pressure of a spring normally acting against the other end of the brake band. Jaws 6, 7 are rigidly attached to the ends of a brake band 3 surrounding a drum 1 fixed to the chassis 2 of the vehicle. The inner end of a lever 10 pivotally connected to the vehicle spring 12 and to the jaw 7 is pivoted to a rod 5 encircled by adjustable springs 4, 14 acting respectively against the jaws 6, 7. When the spring 12 rises, the lever 10 turns about its pivot in the jaw 7 and relaxes the pressure of the spring 4 on the jaw 6 so that the brake band is able to open and slip around the drum 1.

Title: Radio detector for detecting the movement of people or objects in a confined space

Filed: 1973-03-09
Abstract: 1378280 Proximity switching systems G R SALMET 9 March 1973 [21 March 1972] 11516/73 Heading G1N The invention relates to a system wherein the movement of a person or article in the vicinity of an antenna A, varies the tuning of a transmitter coil L energized from an amplifier A1 fed from an oscillator supply O. FEEDBACK from the transmitter coil is arranged to vary the oscillator frequency slightly in a direction to enhance the detuning effect of the body on the transmitter coil. (see "details" overleaf). Applications security monitoring to detect intruders, opening of (metal) safe-doors, controlling advertising display and taped information, automatic door opening, timed passage-way lighting control, counting passers. Additional features:- (i) a differentiating circuit C 3 R 3  in the detector section avoids slow drift effects. (ii) an integrating network with a timeconstant of e.g. 0À5 secs. in amplifier A2 provides noise interference suppression. (iii) a stick-circuit may be provided by applying bias to amplifier A2 over one of the alarm relay contacts K2. (iv) alternatively a holding delay may be provided by a series resistor in the D.C. supply to the detector, so that when the amplifier A2 draws increased current to operate the relay a drop of e.g. 5 volts occurs in the supply and thus applies a 5 volt signal to the differentiating capacitor C 3  which maintains the alarm signal until it has leaked away through R 3 . Details. Fig.7 shows a Hartley transistor oscillator section TR 1  feeding through an amplifier section TR 2  to the antenna circuit L, C 1 . Feedback is transmitted through capacitor C6 to the end g of the oscillator coil for detuning in a sense to enhance the effect of antenna capacity increase due to an intruder alternatively feedback to tapping g<SP>1</SP> on the opposite side of the ground tapping h is used for a decrease in antenna capacity e.g. as in opening of a safe door (and the antenna circuit is tuned, of course, the opposite flank of the resonant peak).

Patent GB-673491-A (GB)
Title: Improvements in or relating to the spinning of polyacrylonitrile filaments
IPC: D01F6/18
Filed: 1950-05-10
Abstract: In the spinning of polyacrylonitrile filaments by extruding a solution of the polymer or a copolymer consisting of at least 85 per cent acrylonitrile in a volatile solvent into a heated evaporative medium, discoloration of the filaments is prevented by previously driving out all the oxygen from the dissolving vessel, filter candles and all the apparatus prior to and including the spinning nozzle by an inert gas, e.g. nitrogen, and by cooling the solution at the spinning nozzle to the lowest temperature which still permits spinning.  Additionally the solution, immediately after formation, may be cooled to the temperature which does not induce gelatinization.  The amount of cooling in both cases is adapted to the concentration and molecular weight of the polymer.  In an example, polyacrylonitrile of molecular weight 30,000 is dissolved in dimethyl formamide at 100 DEG  C. and the solution spun into an atmosphere of nitrogen at 160-170 DEG  C.  The solution is cooled by passing water at 12 DEG  C. through a tube surrounding the nozzle and the whole operation is effected in an atmosphere of nitrogen.  With a polymer of molecular weight 100,000, the cooling water temperature is 80 DEG  C. Specification 595,999 is referred to.

Abstract: 455,383. Fusible cut-outs. SWITCHGEAR & EQUIPMENT, Ltd., Station Road, Banbury, and OXLEY, A. G. H., Greengates, Adderbury West, near Banbury, Oxfordshire. April 18, 1935, No. 11956. [Class 38 (i)] The fuse wire and spring of a spring-loaded fusible cut-out are connected through a lever so that the strain on the fuse wire is restricted. As shown the fuse wire J is connected to the end of the lever K whilst the spring is connected to the lever through the member N. When the fuse blows the spring causes the lever K to rotate and the boss L<1>, pivoted in the insulating plates M, turns into the position indicated in Fig. 5 and slips out of the recess N<2> allowing the pull-off spring to draw-out the arc and facilitate its extinction by means of the arc-quenching liquid with which the cut-out is fitted. The insulating plates may be provided with several holes or may be slotted as shown at R to enable fuses of differing lengths to be used. If desired an additional fuse Q may be provided, the fuse J being the straintaking member which blows when carrying the full load following the fusing of Q. A blow off cap B<1> serves to relieve excess pressure.

Abstract: 1323001 Automatic control of speed FORD MOTOR CO Ltd 29 April 1971 [2 June 1970] 12037/71 Heading G3R The speed of an automatic vehicle is determined by a rotary senser 12 producing a signal, having a speed-dependent frequency f, which is fed to a converter 14 producing a speed dependent direct voltage Vo. This voltage is applied to a comparison circuit 18 at the input of an high impedance amplifier 24 incorporating a fieldeffect transistor. The comparison circuit 18 also receives a reference signal from a capacitor memory 20. The difference output from the amplifier 24 is fed to an amplifier 28 energizing control air valves 30 for a vacuum servomotor 32 positioning a throttle of an engine 36 so as to maintain the speed of the vehicle at the speed set in the memory 20. Throttle position feedback is provided from a transducer 34 to a comparator 26 between amplifiers 24, 28. The desired speed value is set in the memory 20 by the selective closure of a switch 22 since normally, in consequence of closure of an ignition switch, not shown, the system is inhibited and the engine controlled by an accelerator pedal. Facilities are provided for change of the desired speed value at a set rate and the disconnection of the system on application of the brakes or on the occurrence of a large reduction of vehicle speed below the desired speed.
