Abstract: 743,838. Switching and supply systems for electrical equipment on vehicles. BARRIONUEVO, A. R. Dec. 9, 1953, No. 34254/53. Class 38 (4). [Also in Group XXXVII] In a switching system for the electrical circuits of an automobile wherein the usual complex dashboard switch is replaced by two or more switch units located, say, one under the dashboard and one or more under the forward part of the bonnet, with the several units ganged together mechanically for common operation by a single dashboard control, the ganging members are electrically conducting and serve as supply conductors to the units. Fig. 2 shows a dashboard mounting unit 1 operated by a knob 39, which through an insulated rod 176, provided at each end with universal couplings, also operates a unit 2 mounted to one side of the forward part of the car. Another unit 2 on the other side of the car is simultaneously operated by first unit 2 through a rod and crank connection 160, 163. The unit 1 comprises a metal shaft 32, Fig. 3, rotatable by the knob 39, within an insulating housing 3 and carrying (a) a bracket 54, which forms part of the universal coupling at one end of the rod 176, (b) an insulating plate 53 on which is mounted a metal ring 60 provided with a number of projecting contacts, and (c) a spring contact 52 engaging a metal plate 25 which forms a bearing for the shaft 32 and to which current is supplied over a connector 23 joined to a terminal on the outer part of the housing 3. The projecting contacts of ring 60 co-operate with contacts arranged in the end of the housing and connected to terminals on the exterior surface of the housing. Current is conveyed from contact spring 52 to ring 60 through a fuse mounted on the plate 53. A cap 72 is also mounted on the plate 53. The knob 39 is provided with a push-button 48 for moving, against the action of a spring 45, a U shaped contact 48 into engagement with fixed contacts carried by the housing-say for operating a horn. A fuse may also be mounted on the body of the housing. The front units 2 are, generally, similar to unit 1, except that they are provided with fixing eyes instead of a fixing nut 5, and the knob 39 is replaced by metal arms, exteriorly insulated and provided with couplings for connecting to the operating rod 163.

Title: Improvements in and relating to short-wave multiple channel telephony and signalling
IPC: H04B1/54
Filed: 1945-12-21
Abstract: 605,396. Multiplex systems. PATELHOLD PATENTVERWERTIUNGS- & ELEKTROHOLDINGS, AKT.-GES. Dec. 21, 1945, No. 34691. Convention date, Sept. 21. [Class 40 (iv)] [Also in Group XL (c)] In a multi-channel system telephone and signalling (e.g. telegraph) channels are grouped in pairs, each member of which is amplitude modulated by a carrier associated with the pair in question, the carrier and one side band being used for telephony and the other side band for signalling (e.g. telegraphy), to form an intermediate frequency range of less than one octave, which is then used to frequency modulate a transmitter. In Fig. 2, telephone currents of .3 to 3 kc. from the source TA modulate in MS1 a carrier f2 of 16 kc. and filter FS1 passes the carrier and lower side band. Signalling frequencies of 1.5Œ.1 kc. from source ZA modulate f2 in MS2 and filter FS2 passes the upper side band. Second telephony and signalling currents from sources TB, ZB similarly modulate a carrier f of 24 kc. The whole intermediate frequency band extending from 13 kc. to 25.6 kc. lies within one octave, thereby avoiding disturbance by second order modulation products when the whole is transmitted by the frequency modulated transmitter R. The receiver E demodulates the incoming frequency modulated waves to produce the original intermediate frequency band which is then separated by filters FE1, .FE2 and demodulated by telephony and signalling demodulators D1, D2 respectively, the former utilizing the carrier received from the transmitting station and the latter a local source which may be the same as that which supplies the corresponding modulator of the associated transmitter.

Title: Improvements in and relating to time-lag devices of the dash-pot and plunger type
IPC: G04F1/00
Filed: 1933-12-09
Abstract: 411,387. Retractive switches; snapaction switches ; retarding action of switches; hydraulic springs. HAMILTON, W., Woodlands, Wadhurst, Sussex. Dec. 9, 1933, No. 34719. [Class 38 (v).] A quick-action retractive switch with a dashpot time delay device, comprises a switch arm 8 pivoted at 9 and provided with a member 10 for bridging a pair of contacts 11. The arm 8 is connected by a spring 12, which can act both as a tension or a compression spring, to an arm 1 of a bell crank lever pivoted at 3, the other arm 2 of which bears a pin 6, adapted to engage a ramp 7 on the switch arm 8. The cone 1 is shown in an intermediate position in which the spring 12 is not under tension. If the arm 1 is turned in a clockwise direction, the spring 12 is tensioned but the switch arm 8 is restrained until the pin 6 passes off the end of the ramp 7 to allow the switch arm to open rapidly. From this position, if the arm 1 is turned anti-clockwise the pin 6 rests under the ramp 7 and prevents the arm 8 from moving down under the compression of the spring 12 until the pin 6 passes off the right hand end of the ramp 7 and the switch closes rapidly. To enable the switch to be closed for certain intervals, a dashpot 13 is provided with a plunger 14 moving in a viscous liquid such as glycerine, the hollow plunger rod 15 being slotted at its upper end to receive the arm 1 which is connected to the plunger 14 by a compression spring 19. A powerful spring 20 is fixed on a stud 21 and has one arm 22 held by a pin 24. The other arm 23 engages a pawl 16 pivoted at 17 to the arm 1 to bias it and the arm 1 in a clockwise direction. When the handle 5 is sharply depressed the switch is closed as described, and the arm 1 is held by the engagement of the hooked end 25A of the pawl 16 under a fixed abutment 28. The plunger 14 then slowly moves down under the action of the spring 19 until a pin 18 or the forked rod 15 trips the pawl 16. The spring 20 then moves the arm 1 and the plunger slowly upwards to open the switch as described. In a modification the cone 2 is loosely coupled to the arm 1 so that the switch can be opened again quickly independently of the dashpot. Specification 395,801 is referred to.

In the construction illustrated a spring-pressed nozzle plug 15 having a conical face is pressed by a spring 22 against the internally-coned end of the burner tube 10 or a cap 12 on the burner tube 10. The nozzle plug fits the bore of the burner tube at its front and rear ends, and between its ends is formed with an apertured reduced portion 18. Oil fed to the burner tube is strained by passing through sawcuts or perforations in the reduced portion 18 into the surrounding annular chamber 17 and then passes through channels 25 in the end of the plug and tangential grooves or channels 16 in the conical face to a central delivery orifice 13 in the cap 12. Means may be provided to prevent the rotation of the nozzle plug in the burner tube. In a modification the nozzle plug is of uniform diameter throughout and the bore of the burner tube is enlarged around the apertured portion of the nozzle plug to form the annular chamber through which the oil passes to the delivery orifice.

Abstract: 1395372 Anti-overturn warning device for vehicles L A MIZE 26 July 1972 35025/72 Heading B7H A vehicle is provided with an anti-overturning warning device which comprises switching means 20 mounted on a vehicle frame 15, said means being actuated by a lever 21 attached, via a slack cable 22, to an axle 16. A decrease in the effective weight of a load acting on a wheel 18, for example during cornering of the vehicle, causes the distance between the frame 15 and axle 16 to increase thereby taking up the slack in the cable 22 until, at a predetermined frame/ axle distance, the lever 21 is pivoted to activate the first of a series of microswitches in the switching means 20 thereby lighting a warning lamp 24. Further increase in the frame/axle distance activates a second microswitch which illuminates a further lamp 25. Thus a succession of warning lights are activated as the danger of overturning increases.

Abstract: 1395927 Fluid oscillators JOHNSON SERVICE CO 28 July 1972 [29 July 1971]  35471/72 Heading G3H In a pulsating signal generating device, a pressurized fluid stream 4, Fig. 1, e.g. air, issuing from a nozzle 3 is partially impeded by a resilient or resiliently-mounted elongate member 10. The member extends perpendicularly with its axis laterally offset from the path of the stream, whereby the stream causes it to oscillate and generate a pulsating signal which is collected by a nozzle 6. Alternatively, the signal may be collected by detecting the movement of the member 10 by photo-electric means or the like. The member 10 is formed by a resilient tube 11, e.g. of spring stainless steel, and by a resilient rod 17, e.g. of spring steel, axially adjustably mounted within the tube to regulate the frequency of oscillation. Alternatively, the frequency may be varied by adjusting the mounting of the member, or the amplitude may be varied by controlling the supply pressure of the stream. In an alternative embodiment, Fig. 5 (not shown), a stream-impeding vertical rod (19) is hinged at its lower end and is biased into a stream-impeding position by a spring- loaded plunger (22) acting on its upper end. Alternatively, the stream impeding means may be constituted by two contiguous cantilevers slidable longitudinally relatively to each other.
