Title: Improved system of and apparatus for radio communication
IPC: H04K1/00
Filed: 1923-06-11
Abstract: 202,278. Hammond, J. H., (Assignee of Chaffee, E. L.). Aug. 11, 1922, [Convention date]. Secret and selective signalling systems; thermionic homodyne receivers; thermionic modulating systems; multiplex signalling.-In order to prevent unauthorized listening-in, the signal frequencies are first impressed upon an intermediate supersonic frequency, one of the resulting sideband of frequencies being filtered out whilst the other side band is utilized to modulate the highfrequency carrier wave. The supersonic frequency is also normally suppressed, so that radiation takes place only when the microphone is energized. The receiving-station is provided with a local generator of oscillations of the same supersonic frequency as that suppressed in transmission. In addition, the frequency of the main carrier wave may be periodically varied in an erratic manner. More than one supersonic frequency may be combined with the same carrier wave for multiplex working, and the system is also applicable to radio-dynamic control. The valve 20, Fig. 1, generates oscillations having a frequency, say, of 40,000, which are fed through a transformer 22, 24 to the grids of two modulators 33, 34. Signal frequencies from a transmitter 32 are superposed upon the first oscillations through a transformer 31. The plate outputs from the modulators 33, 34 are so opposed across the transformer 35 that the supersonic frequency is suppressed except when the transmitter 32 is active. A filter 36 is designed to pass only the lower side-band frequencies, which are then, in turn, applied to a modulator 41 placed in shunt with the carrier-wave generator 10 across the high-tension supply. The radiated energy is accordingly modulated with those signal components that have passed the filter 36. The aerial-circuit constants are varied in an irregular manner by means of a pair of contacts 51, 52 which intermittently close the circuits of shunt condensers 53, 54, whilst a rapidly rotating vane 55 passes across a stationary condenser plate 56. At the receiving-station, Fig. 2, the grid circuit 63, 64 of a back-coupled rectifying-valve 66 is tuned to the main carrier-wave. The rectified current is fed by a transformer 74 to a circuit 78, 92 tuned to the unsuppressed side band of the modulated intermediate supersonic frequency. This circuit forms the input side of the final detector 100, which is also fed through a coupling 83 with oscillations from a valve 80 of the same frequency as the initially suppressed supersonic frequency.

Title: An improved induction air system for internal combustion engines
IPC: F02M31/07
Filed: 1970-04-01
Abstract: 1277521 Valves FILTERWERK MANN & HUMMEL GmbH 1 April 1970 [2 April 1969] 15363/70 Heading F2V [Also in Division F1] The flap valve 7 which controls communication of an unheated air passage 3 and a preheated air passage 4, e.g. connected to a pipe opening in proximity to an I.C. engine exhaust pipe or manifold, with an inlet pipe 2 of an engine air filter 1 is operated by a thermostat 12. The thermostat pin 17 operates the valve 7 through a rod 19 slidable in a sleeve 20 which is urged against a crank-pin 26a on the valve shaft 6 by a spring 22 acting between the sleeve and rod. The movement of the shaft 6 by the spring 22 is limited by a member 30 engaging a crankpin 27a on the shaft and co-operating with a stop 25 on the rod 19. The crank-pin 27a has a larger crank-arm than the crank-pin 26a and outward movement of the pin 17 moves the valve 7 from a position closing the passage 3 to a position closing the passage 4, the spring 22 being compressed by virtue of the larger crankarm. Further outward movement of the pin 17 is taken up by spring compression. The shaft 6 is journalled in a frame 10 which may be removed from the pipe 2 with the cover 11.
Patent GB-374251-A (GB)
Title: Improvements in vehicle control for brake and door apparatus
IPC: E05F15/02
Filed: 1931-05-26
Abstract: 374,251. Controlling motorbus doors. NATIONAL PNEUMATIC CO., 420, Lexington Avenue, New York, U.S.A. May 26, 1931, No. 15423. Convention date, May 28, 1930. [Class 79 (v).] Means for controlling motor bus doors comprise pneumatic door-operating motors which cannot be operated to open the doors until the brakes are applied and while the doors are open the brakes cannot be released or the accelerator depressed. Further the doors cannot be closed until the doorway is clear of passengers. The vehicle is stopped by brake pedal 7 which operates valve 6 to pass fluid from a source 8 through pipe 4 to the brake cylinders 2. Fluid also passes through pipe 9 to operate pneumatic switch 10 and interconnect wires 22, 23. Current then flows through wires 20, 22, 23, 24 to switch 25 and through wires 23, 54 to stop lamp 55. When the bus stops the switch 25 is momentarily closed by the operator and current flows through wires 26, 27 to energize a magnet 33 and pull over a lever 31 which prevents depression of the accelerator 29. Current also flows through wire 26 to energize a magnet valve 36 and connect ports 110, 111, Fig. 3. This exposes a plunger 83 to fluid pressure and presses it against a valve seating thereby closing exhaust passage 81. When plunger 83 is seated a ball 82 of a check valve moves to the right against the action of a spring and exposes the cylinder of a pneumatic switch 12 to the fluid. The consequent movement of the piston bridges contacts 34, 70 and establishes a holding circuit for the magnet valve 36 so that it remains open after the switch 25 is opened. If a passenger is standing above one of the treadle switches 37 circuit 24, 70, 36<1>, 37, 38 is completed and a magnet valve 39 is operated to throw open the larger cylinder of the pneumatic dooroperating motor 41 to the atmosphere and open the door. Should an attempt be made to release the brakes while the doors are open by removing pressure on the pedal 7 to cut off the fluid supply, fluid under pressure will flow from the switch 12 through pipes 79, 5, 4. As soon as the treadles 37 are free magnet valve 39 is de-energized and fluid pressure is supplied to the large cylinder of the door engine to close the doors. As they close a drum 48 breaks the holding circuit of the valve 36 and establishes the circuit to the signal light 53 indicating that the doors are closed. The doors can be operated without a passenger standing on the treadle switch 37 by closing a switch 57. Further the doors can be opened from outside the motor bus by a key-operated switch 59.

Abstract: 1294376 Dryers; radiant-heat burners GOODYEAR TIRE & RUBBER CO 2 April 1970 [2 May 1969] 15643/70 Headings F4G and F4T An apparatus for drying fibrous yarn or fabric in the form of a long element 12 comprises a tower 10, which may be 100 feet tall, with sixteen identical drying units. The element 12 is driven, under tension, from drum 21, through dip 18, which contains a fibre-torubber adhesive, up inside tower 10 along path 12a and down path 12b inside the tower (or path 12 outside) to the drum 25. Inside the tower the heater 31 may be a gas-burner of the mat type fed by gas from inlet 34, it emits infra-red radiation which dries the element 12. Interposed between the heater and the element is a shield 62 composed of slots, as in a venetian blind, which may be rotated to vary the amount of radiation reaching the element. The rotation is controlled, ultimately, by the speed of the element 12 so that when the element is travelling slowly, the shielding effect is great. Additional heat control may comprise the automatic adjustment of the flow of gas to the burners. Air may be drawn from the outside, forced at a variable rate out of nozzles 50, whence it travels at up to 6800 f.p.m., and collected by nozzles 56 its function being to remove, from the surface of element 12, water vapour, volatiles and other products of the hot element which would inhibit the passage of infra-red radiation from the heater to the element.  Burners.-The heater 31 (Fig. 4) comprises mat-type gas burners 32, fed with a fuel gas/air mixture, and spacer blocks 33 arranged in frame 30 so that their numbers and distribution may be altered to change the intensity and pattern of the radiation. Fuel gas flows under pressure from main 34 to a zero governor 35a which reduces it to atmospheric pressure and introduces it to the throat of a venturi 35b where it is entrained in an air flow due to blower 35c under the control of butterfly valve 35d which is operated by piston 117p. The heating effect of the burners may also be varied by moving the frame 30 to and from the element 12 by means of piston 115p and by opening and closing the shutters 62 by means of piston 70p. Pistons 117p, 115p and 70p are actuated by valves 105a, 103a and 101a respectively in response to signals from a temperature sensor 107a and an elementspeed sensor comprising follower 109a, governor 109b and switch bank 109.

Abstract: 379,369. Electromagnets. FRITCSONS, J., 8, Martina eila, Riga. May 29, 1931, No. 15806. Convention date, July 11, 1930. [Class 35.] An electromagnet comprises two elements C, D the energizing coils of which are arranged in the same circuit, and two interengaging armatures G, F arranged at opposite ends of the cores in such a manner that one, G, moves first to release the other F, and in approaching the cores decreases the air gap in the magnetic circuit so that there is an increased attraction on armature F which is normally prevented from moving under the influence of shocks. The spring g controlling the armature G is weaker than the spring f of the other armature, or other means such as different weighting or spacing of the armatures may be employed to ensure that the armature G moves first. The armature F is held by a notch h in an arm H secured to the armature G. The Specification as open to inspection under Sect. 91 (3) (a) describes a construction having a single magnet core and also a construction in which the armatures do not interengage. This subject-matter does not appear in the Specification as accepted.
