Title: Combined direction indicator and a warning flash switch
IPC: B60Q1/14
Filed: 1968-07-29
Abstract: 1,201,726. Mechanical switches. SWF-SPEZIALFABRIK FUER AUTOZUBEHOER GUSTAV RAU G.m.b.H. 29 July, 1968 [29 July, 1967], No. 36020/68. Heading H1N. A switch for operating the flashing direction indicators of a motor vehicle and which may be directly mounted on the steering column, is provided with an additional contact movable manually to a position in which it bridges all three contacts of the switch so causing all the direction indicator lamps to flash simultaneously as a warning. The direction indicator switch comprises three fixed contact pillars 14, 15, 16, supported by an insulator 13 from a flange 11 on the steering column, and a bridging contact 20 carried resiliently by a rotary member 19 coupled to an operating lever (not shown). In a central position of member 19 contact 20 engages only the fixed contact 15 which is connected to the battery through the ignition switch (63) and a flasher unit (23) (Figs. 6, 7, not shown); in either end position contact 20 bridges contact 15 to either of contacts 14, 16 respectively connected to the left- and righthand direction indicator lamps (21, 22). Mounted to slide upon the three contact pillars 14, 15, 16 is an insulating member 25 containing a lamp 42 and carrying a spring blade contact assembly 32. The lower wall of member 25 is resilient and carries a cam portion 28 which provides a click action. When member 25 is slid from the position shown to its other extreme position the blade assembly 32 is moved to bridge all three contact pillars 14, 15, 16. In addition assembly 32 is connected to the lamp 42 by a blade spring 37 so that all the direction indicator lamps 21, 22 and lamp 42 flash together. The blade spring 37 is arranged to bias the lamp 42 out of the member 25, about a pivot 43, when a cover 44 is slid off. Additional contacts 56 (58, 60) (Fig. 2, not shown) mounted respectively on members 25 and 13 are arranged to by-pass the ignition switch (63) when the warning flash switch is operated. A push-pull operating member may be used for the warning flash switch (Figs. 6, 7, not shown).

Title: Injection pump for reciprocating piston internal combustion engines
IPC: F02M41/06
Filed: 1961-10-06
Abstract: 943,515. Fuel injection pumps; rotary vane pumps. FIAT S.p.A. Oct. 6, 1961 [Oct. 7, 1960], No. 36050/61. Headings F1A and F1F. In a fuel injection pump comprising fixed radial cylinders with pistons 14 reciprocated by an engine-driven cam track 6, 6a, an enginedriven valve stem 17 controls the pump inlet ports 10 and is movable axially and angularly by means responsive to engine speed to vary the pump delivery and injection timing, respectively. Valve stem 17 is formed with a trapezoidal land 18 for controlling flow between inlet ports 10 and an annular chamber 11 supplied with fuel by a vane-type feed pump 45. Duration of delivery is controlled by axial movement of stem 17 by centrifugal weights 25 pivoted on a hub 26 of drive shaft 3, Fig. 3. This axial movement is opposed by a spring 27 acting on stem 17 through a lever 30, a roller 33 and a lever 38. The vertical location of roller 33 is adjustable through a lever 36 and work 35 to vary the spring loading on stem 17 and thereby vary the effect of weights 25. With roller 33 in its lowest position, for idling, spring 27 has little effect, resulting in sensitive action of weights 25. With roller 33 in its highest position, for maximum speed, spring 27 strongly counteracts weights 25. For extra delivery at the maximum speed position, a spring 43 acts through a lever 42 against spring 27. Stem 17 is driven by shaft 3 through a sleeve 21 slidably connected to stem 17 by a pin 21a and rotatably and slidably connected to shaft 3 by a pin 24 located in an off-set groove 23. For varying the timing, centrifugal weights 28, Fig. 4, act on sleeve 21 against a spring 22, the action of pin 24 in slot 23 rotating sleeve 21 and stem 17 relative to shaft 3. A light spring 41 between a thrust bearing 40a and a cap 39 on the end of stem 17 urges the stem into a maximum delivery position for starting the effect of spring 41 being cancelled when the engine is running. Hydraulic braking of inward movement of pistons 14 is provided by a groove 18a, Fig. 3, in hand 18 which communicates with the pump casing via a throttled orifice 18b. A stop valve is provided between the feed pump and inlet chamber 11. The feed pump comprises a rotor 46, Fig. 7, splined on shaft 3, Fig. 1, and housing vanes 47 urged outwardly by resilient rings 48 to engage the pump chamber wall 45a.

Abstract: 1,071,334. Moulding gramophone records. DECCA Ltd. Aug. 26, 1964 [Sept. 16, 1963], No. 36305/63. Heading B5A. In a method of making gramophone records, pre-formed blanks, which require only embossing of the sound track thereon to complete manufacture, are each heated over a substantial portion of their central regions prior to the embossing process. Blanks are rolled one at a time down a nylon tracked channel 32, Fig. 2 (not shown), to enter a slot 22, Fig. 1, where each is held in turn by a latch 27 between continuously operating radio-frequency or radiant heaters 21, e.g. tungsten-iodine lamps. The portions of the blanks which are heated are determined outwardly by hoods 26 and inwardly by shields 34,. the latter preventing distortion of the spindle hole 12. After a predetermined heating period, e.g. 1 second, latch 27 is rotated to allow the blank to drop between grooved nylon guides 33, Fig. 2 (not shown), to a cleaning station, described in Specification 1,071,332 and thereafter the blank is transferred to the embossing station, described in Specifications 1,071,335 and 1,071,333. A lamp and photo-cell device 31 prevents acceptance of a further blank when the light path is blocked and causes heaters 21 to be switched off if blocking occurs for more than a predetermined period.

Abstract: 1,149,587. Controlling clutches. LITOLLO A.S. 9 Aug., 1967 [14 Sept., 1966], No. 36581/67. Heading F2L. In a friction, claw, or facial pin and recess coupling comprising a first member 10 freely rotatable on a shaft 1, which is hollow at least at one end, a second member 7 rotatable with but axially slidable along the shaft 1 and urged by a spring 8 into coupling engagement with the first member 10, insertion of a hand crank 12 into the hollow shaft end first disengages the coupling and then brings the projecting ends of a pin 13 through the crank 12 into driving engagement with slots 14 in the end of shaft 1. In Fig. 1, curved radial pawls 4 pass through slots 3 in shaft 1 into slots 6 of member 7 to couple member 7 to shaft 1. When crank 12 is inserted, its end pushes the pivoted together ends of pawls 4 causing them to urge member 7 against spring 8 to disengage the coupling. Then the pin 13 engages the slots 14. When the crank 12 is released, spring 8 acts via member 7 and pawls 4 to push it out of engagement with collar 9. In Fig. 3, the crank acts on a transverse pin 15 keying the member 7<SP>1</SP> to shaft 1<SP>1</SP> to push the member 7<SP>1</SP> out of engagement with the member 10<SP>1</SP>, against spring 81.

Abstract: 1,151,356. Controlling reactors. EUROPEAN ATOMIC ENERGY COMMUNITY (EURATOM). 25 Aug., 1966 [26 Aug., 1965], No. 36752/65. Heading G6C. In a fast nuclear reactor, rapid decrease in reactivity is effected by separation of the fuel rods due to temperature induced dimension changes. An outer circumferential securing band round the rod assembly permits lateral expansion of the core and may also fracture, at a predetermined expansion, to effect a further separation of the rods, to produce shut-down. The fuel rod tapered upper ends are each located by the surfaces of a horizontal grid formed of separate elements closely engaging the tapers. The grid elements are urged vertically downwards into engagement with the fuel rod tapers by gravity or springs. The separate grid elements are forced apart, against the action of the securing bands, as the fuel rod upper ends are moved vertically upwards by a thermally induced increase in length.

Abstract: 399,053. Retort furnaces. HELLMANN, O., 6. Oscar Hoffmannstrasse, Bochum, Germany. Dec. 30, 1932, Nos. 36923 and 36924. Convention dates, Dec. 30, 1931, and June 20, 1932. [Classes 51 (i), 51 (ii), and 55 (i).] In a retort furnace for coking, comprising an annular rotary charge-supporting platform 14 disposed immediately above radial heating flues s, the platform is divided into sectors by low radial partitions 17, Fig. 3, and pressure elements x, which can be lowered on to the charge, are fitted in apertures 20 in the furnace roof. The lower faces of the elements x are formed with ribs 21 which, when the sections are lowered, subdivide the charge sectors into strips or blocks. The heating flues s receive hot gases from combustion chambers s<1> to which gas is supplied by nozzles 10 and air, preheated in recuperators q<10>, q<11>, through apertures 11. The nozzles 10 are supplied with strong gas through pipes 6 leading from a distributing chamber surrounding the main bearing pin 4, this chamber having a fixed lower part 3 into which the gas main 36 delivers, and a rotary upper part 5 carrying the. pipes 6. Fig. 6 shows a modification adapted for alternative firing by strong or weak gas, the latter being supplied through the hollow pin 4 and pipes 15 to preheating chambers q<20> disposed between the recuperators q<10>, q<11> and communicating with the combustion chambers s<1> through ports 16. The entire rotary structure, comprising the platform, the combustion chambers and heating flues, and the air or air and fuel preheaters, is embraced by hoops 28 formed in sections connected together by springs. Apertures, closable by blocks 13, are provided for the admission of cold air to attemperate the hot gases passing from the combustion chambers s<1> to the heating flues s. The charge is supplied from a hopper 38, while the coked product is removed, one sector at a time, by a scraper 22 which is of dished formation, as shown, so that when inserted into an empty sector, further rotation of the platform is not interfered with. The scraper, which operates through an aperture fitted with a hinged flap 39, withdraws the coke into a closed chamber 40 to which a cooling medium, such as air or steam, is supplied at 26. The gases from the cooling chamber either pass into the coking space and are withdrawn with the distillation gases at 19, Fig. 3, or they are taken off and utilized for preheating the charge prior to its delivery to the platform 14. Alternatively, the waste gases from the heating flues s may be used for this preheating, in which case the collecting flue t and stack 12, shown in Fig. 1, are dispensed with. The preheating is effected by passing the hot gases through a rotary drum which serves to deliver the charge to the platforms 14 of two furnaces simultaneously.

In the polyphase arrangement shown, bimetallic elements 1a ... 1c are heated by heaters 2a ... 2c and move slides 24, 25, the slide 25 moving a slide 27 having a member 28 carrying the end 11 of the pipe 30 and the slide 24 having an aperture 23. In the event of overload or unbalance, relative motion between the slides 24, 25 causes the alignment of the end 11 and aperture 23 so that air escapes from the pipe 30. The resulting loss of pressure acting on the diaphragm 31 causes the pneumatic relay 32 to change over and vent the compressed air from the pneumatic contactor which opens its contacts 6a ... 6c. Re-setting is effected by a push-button 30 moving the slide 27 back to stop the outflow of compressed air. The rise in the pressure acting on the diaphragm 31 operates the pneumatic relay 32 to close off the vent to atmosphere and to supply compressed air to the pneumatic contactor which closes its contacts 6a ... 6c, Figs. 1 and 2 (not shown), illustrate single phase arrangements and, Figs. 4 and 5 (not shown) illustrate modifications of the mechanism controlling the outflow of compressed air.
