Title: Vacuum cleaning implement
IPC: A47L9/06
Filed: 1971-08-27
Abstract: 1311079 Vacuum cleaning nozzle ELECTROLUX Ltd 27 Aug 1971 [30 Sept 1970] 40287/71 Heading A4F [Also in Division E2] A cleaning nozzle includes a fixed flat elongate mouth 12 and a brush 48 which is movable from an inoperative position, Fig.4, in which the mouth 12 contacts the working surface to an operative position on which it contacts the working surface, Figs.5 and 6, (not shown). The brush is mounted on a pair of frame members 17, 18, Fig.2, (not shown) movable vertically on guides 19, 20. Frame 17 is acted on directly by an actuating mechanism, and frame 18 is connected to frame 17 by a crank rod 32, Fig.2, (not shown) so as to move with frame 17. The actuating mechanism includes a control member 21 having a lever pivoted at 23, an extension 35 on the lever, and a latch 36. Latch 36 is pivoted on a shaft 37 and biased by a spring 43 to the position shown in Fig.4. As shown in Fig.3, the latch 36 is mounted on shaft 37 so that it may tilt in the plane of the Fig. a spring 50 biasing the latch to the vertical position. A tongue 46, Figs.3 and 4, is pressed out of the latch 36. When the control member 21 is depressed from position A to position B, Fig. 3, it pushes frame 17 downwardly so that the brush is moved to its operative position, the force being transmitted to frame 17 via spring 56. At the same time, extension 35 rides along cam 44 on latch 36 and into detent 45 to lock the control member in position B, Fig. 5, (not shown). To release the control member, it is depressed into position C, the control member moving relative to frame 17 by cup 27 sliding through aperture 30 in frame 17, Fig.1. As the extension 35 moves downwards to the bottom of detent 45, the latch 36 is pivoted anti-clockwise by spring 43 so that extension 35 lies below tongue 46 on latch 36, Fig.6, (not shown). On release of control member 21, spring 28 urges firstly the control member and then the control member and the frame 17 upwardly, the extension 35 acting on tongue 46 to pivot latch 36 clockwise in the plane of Fig.3, to allow the control member to return to position A unimpeded.

Title: Improvements in signal operating means
IPC: B61L21/04
Filed: 1957-12-31
Abstract: 840,473. Railway signals. TURNER, S. C., and KOFLER, G. Dec. 31, 1957, No. 40406/57. Class 105. The actuating device 3 of a signal normally in the " danger " aspect and operated as by the core of a solenoid 4 against loading, e.g. gravity, into its " clear " aspect, is held in its " clear and " danger positions by a latch device comprising a latch member 9, Fig. 3, on a shaft 10 coupled by an arm 11 to the movable core 13 of a latch solenoid 14, which on operation, as by a " clear " signalling current through the double-pole A.C. relay 20, Fig. 2, closing the energizing circuit for the solenoid 14 at contacts i, rocks the latch 9 over from the position in which it latches the actuating device 3 in the " danger " position by engaging in an opening 7 in the latch bracket 6 of the device 3, towards the alternative position and in so doing a cam device 16 temporarily operates a switch 17, Fig. 3, closing contacts 19, Fig. 2, to energize the contactor device 21 over contacts j of relay 20. In the first part of its movement the latch 9 engages the bracket 6. The contactor 21, on operation, at its closed contacts k and l energizes the solenoid 4 for operating and lifting the device 3 to actuate the signal to " clear " aspect, drawing the bracket upwardly to enable the latch 9 to engage in the opening 8 of the bracket to hold the signal at " clear." During this final movement the cam device 16 releases the switch 17 to open contacts 19, Fig. 2, to de-energize the contactor 21 followed by the de-energization of solenoid 4. On release of the relay 20 by the interruption of signalling current the latching solenoid 14 is de-energized and the core 13 drops under gravity, rotating the latch 9 and releasing the signal to return to " danger " under gravity, whereupon the latch 9 re-engages in the opening 7 in the bracket 6.

Title: Flasher switch
IPC: G08B21/00
Filed: 1972-09-05
Abstract: 1377408 Lamp failure indicator TRIDON Ltd 5 Sept 1972 [10 Sept 1971] 41159/72 Heading G4N A lamp flasher circuit giving lamp failure indication by a change in flashing rate comprises a relay 15 having contacts 25, 26 and two opposing coils 16, 17 one of which is connected in series with a capacitor 20, and means 19 for detecting the magnitude of the current flowing through contacts 25, 26 when closed, to connect an impedance 21 in series with one of the windings when the current passes a threshold value, to change the flashing rate. On closing switch 28, opposing currents flow initially through windings 16, 17 of relay 15, so that contacts 25, 26 are not closed. As capacitor 20 charges, the current in winding 17 falls and the, now larger, current in winding 16 closes contacts 25, 26 to energize lamps 14, and short out the relay windings. The currents in the two windings now decay until the relay releases and the cycle recommences. With both lamps lit, reed relay 19 operates shorting out resistor 21, but if one fails, resistor 21 remains in circuit, reducing the decay time of the current through winding 17, and thus increasing the flashing rate. In a modification, the resistor 21 may be replaced by an additional winding on core 15. In another modification, Fig. 2 (not shown), the reed relay is replaced by a transistor circuit.

Abstract: 1,095,002. Measuring attenuation. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 5, 1966 [Oct. 12, 1964], No.41545/64. Heading G1U. In an apparatus for determining the attenuation produced by a test piece comprising a component part of an H. F. transmission line system 3 such as a waveguide, a microwave source 1 is connected via a known loss directional coupler 4 to a waveguide 2 and to the waveguide system 3 containing the test piece, in parallel. The energy applied to the test piece is modulated at 5. A hybrid coupler 7 adds the signals from the guide 2 and the test piece and supplies them to a rectifier system 10, 11 producing a unidirectional signal of amplitude dependent upon the attenuation produced by the test piece. Arrangements 14-18 measure the amplitude of the unidirectional signal. The measurement is effected by passing the output to a calibrated attenuator 15 which is adjusted to provide a standard reading on a meter 18, and then inserting a unit of known attenuation in the place of the test piece and determining the attenuation required to produce the same reading. The modulating arrangement 5 may be a variable impedance PIN diode mounted in a waveguide, to which a square wave modulating voltage may be applied. The hybrid coupler 7 may be a 3db or magic Tee coupler.

Abstract: 1,063,300. Controlling burners; hot-water boilers. JUNKERS & CO. G.m.b.H. Oct. 31, 1963 [Nov. 15, 1962], No. 42964/63. Headings F4A, F4F and F4T [Also in Division F1] A starting device for a pulsating combustion chamber 10 comprises a mercury switch 37 actuated by a first diaphragm 34 subjected on one side to the pressure in the combustion chamber and on the other side to the pressure of the gas supply, the switch controlling a motor driving an air feed device 32 and a sparking or glow plug 33 mounted in the combustion chamber. At starting gas flows through a pipe 31 to the underside of the first diaphragm 34 causing the mercury switch 37 to energize the air feed device 32 and the sparking plug 33. The pressure built up by the air feed device is conveyed by a pipe 41 to the upper side of a second diaphragm 43 which opens a gas valve 42 to supply gas to the combustion chamber through a pipe 19<SP>1</SP> and a non-return valve 16. The average pressure of combustion in the combustion chamber is conveyed by a narrow bore pipe 50 to the upper side of the first diaphragm 34 and causes the mercury switch to de-energize the sparking plug and the air feed device 32. The vacuums produced by the pulsating combustion are transmitted by the non-return valve 16 and the fuel pipe 19<SP>1</SP> to the underside of the second diaphragm 43 and cause the gas valve 42 to open and close in synchronism with the combustion. If ignition does not occur a static air pressure is built up slowly in the combustion chamber and causes the mercury switch to deenergize the sparking plug and the air feed device. The gas valve 42 therefore closes and the starting process then repeats The repeating of the starting process is limited to six or eight times by a thermal delay 56 in the electric circuit. The gas valve 42 may be arranged to be opened at starting by partial vacuum instead of by pressure, the pipe 41 then branching from the suction side of the air device 32. The burner heats water flowing in a pipe 23 wound spirally around a resonant tube 12 and the combustion chamber 10. The flow of water is controlled by a non-closing valve 22 operated by a third diaphragm 26 subjected at opposite sides to the inlet and throat pressures of a Venturi in the water pipe 23. The diaphragm 26 also actuates a further gas valve 27. The gas is also controlled by a manually operated shutoff valve 20.

Filed: 1971-09-16
Abstract: 1332848 Labelling machine VAUTIER FRERES SA 16 Sept 1971 [17 Oct 1970] 43297/71 Heading B8F A labelling machine employs a rotary head 7 having a segment 12 which carries labels by suction from store 9 via gluing roller 23, supplied from reservoir 20, to label articles3, such as cigar boxes, moved by conveyer 4. Compressed air replaces the suction to apply the label and the gluing roller is retracted if no label is received on segment 12. The lateral surfaces of head 7 and a fixed distribution ring 13 are in contact and the alignment of a feed channel to sector 12, opening in the one face, with a groove 15 connected to a vacuum source 17 in the other ensures that sector 12 receives suction over the correct period. A compressed air outlet (not shown) situated either in the downstream end of the groove 15 or just downstream of it communicates with the same feed channel when the label is in position to be applied. Roller 18 engages groove 19 to release a label from store 9 and if no label is received on the sector 12 a vacuostat 28 senses the pressure increase and activates an electromagnet 27 to retract the gluing roller 23. Sector 12 is interchangeable to suit the label size, and the store holding the articles 3 can be modified to accommodate different sizes of articles, and the height of head 7 above the conveyer may be adjustable. The labels may be applied so that one end projects beyond the leading edge of the article for folding round three sides and in this case a pivoted folding member 30 on drum 29 folds part of the projecting end on to the front edge of the article. The remaining part of the label then projects downward through opening 31 and movement of the article causes the edge of the opening to fold it against the underface.
