Title: Improvements in or relating to warning devices against rough handling, primarily for dolls
IPC: A63H3/33
Filed: 1969-05-07
Abstract: 1,207,637. Toy - mounted gramophone. DICKER TOY DEVICES Inc. 7 May, 1969 [19 June, 1968], No. 23287/69. Heading G5R. [Also in Division H1] A gramophone in a doll is energized to play back a record of a crying noise via an inertia switch which operates when the doll is roughly handled. The switch (see Division H1) actuates a transistor circuit, connected in series with the gramophone motor, to its conducting state and the circuit is held in that state until a further switch is operated by the gramophone tone arm when play-back of the record is completed. Tone arm 33 which is biased out of engagement with record 30 and into engagement with stop 36 by a spring member 37 is urged into play engagement with the record by a speaker supporting end of a bifurcated member 44 which has two arms 45 pivoted on supports 46 and is urged towards the record by blade spring 48. At the end of record play the tone arm moves a further arm 38 towards the record centre to a position in which it is engaged and lifted by a cam member 30a on the record. The arm 38 then pivots the bifurcated member 44 out of engagement with the tone arm and this is returned by spring 37 to its start position. The arm bounces on its return first closing switch contacts 51, 52 to break the hold circuit and thus stop the motor and then allows the contacts to open to reset the circuit.

Filed: 1962-06-18
Abstract: 999,298. Conveying and displaying baggage. MATHEWS CONVEYER CO. Ltd. June 18, 1962 [July 11, 1961], No. 23289/62. Heading B8A. The apparatus is employed for conveying parcels and baggage from an arriving aircraft or ship to the luggage room for display to the arriving passengers so that they may pick out their individual baggage and comprises an endless conveyer 30, an endless belt 36, an idler roller 46 and a rotary conveyer 50. Rotary conveyer 50, Fig. 4. The conveyer has a conical aluminium surface 60 secured to frame 69 which runs on rollers 70, the rollers being driven slowly from motor 81. The conveyer is contained in a fixed outer circular wall 19, and the wall carries annular rubber ring 25 which co-operates with rubber bumper 66 carried by the conveyer so that the baggage slides down on surface 60 till it is held by bumper 66 travelling with the surface 60, while rubber ring 25 constitutes a safeguard to prevent the passengers' fingers being trapped. Operation.-Baggage is carried by endless belt 30 from the aircraft or ship and is then conveyed by endless belt 36 and falls over roller 46 on to the surface 60 of the rotating conveyer 50. The baggage slides down surface 60 as it is being conveyed rotarily and comes to rest against the rubber bumper 66. The baggage is thus rotated on display to the arriving passengers for them to pick out their personal baggage. The roller 46 is so positioned between the conveyer surface 60 and belt 36 that a piece of baggage cannot simultaneously rest on the conveyer and the belt.

Title: Improvements in or relating to sectional boilers
IPC: F24H1/32
Filed: 1930-08-02
Abstract: 354,545. Sectional boilers. CRANEBENNETT, Ltd., 45, Leman Street, London. Aug. 2, 1930, No. 23308. [Class 123 (ii).] In a boiler built up of transverse sections enclosing the furnace, water flows from the legs 5, 6 at the sides of each section upwards through water spaces 7 extending over the furnace chamber, then through a central vertical passage 8 between flues 15, 16, and then outwards and upwards through passages 12, 13 between the flues 15, 16 and an upper flue 17. Baffles 18, 19 direct the water from the legs into the water spaces over the furnace. The gases pass forwardly through the flues 15, 16 and return through the upper flue to the outlet. The single upper flue may be replaced by a number of separate flues.

Title: Improvements in or relating to timing devices
Inventor: FOLLIOTT HUGH BUTLER
IPC: H01H53/12
Filed: 1956-07-28
Abstract: 814,553. Toasters. KENWOOD MANUFACTURING CO. Ltd. July 25, 1957 [July 28, 1956; Oct. 12, 1956], Nos. 23387/56 and 31177/56. Class 28 (1). [Also in Group XXXVII] A timing device for an electric toaster comprises a rack bar 49 actuated by a bi-metallic strip 68, the movement of the rack bar being slowed down or allowed to accelerate by its rotating through reduction gearing 53, Fig. 4, an aluminium disc 46 rotating in a slot in the field of a permanent magnet 55, the speed of the disc and magnet being affected by the ambient temperature in the toaster. Bread placed on cross-bars 21 of parallel links 13, 14 is lowered by hand depressing a knob on an arm 69 so that a nose 31 engages a ledge 32 to press and hold the bread down whereby a ledge 32 of transverse plate engages under a nose 31 on a latch arm 29. The remote ends of links 13 pivot up to tension springs 18 and moves switch arm 24 to close the switch to energize the heating element 12. The downward movement of 17 also tensions springs 61, thus pulling down the cross-bar 57 and the rack bar 49. The rack 49 is pulled down to rotate disc 54 through gears 53 and roller 59, Fig. 3, moves down to engage cam edge 42 on 41 which pivots out, taking with it the nose 31 clear of ledge 32 so that the bread plate 17 jumps up. Toasting time depends on the distance which roller 59 has to travel before displacing latch arm 29, Fig. 1, sufficiently to release 31 from 32, and also depends on the rate at which pinion 51 revolves. The distance which 59 has to travel is set manually by rotating spindle 35, Fig. 2, thus moving cross-bar 37 and bar 41 up or down. The pinion is braked by magnet 55 on disc 54 and since this braking effect decreases as temperature rises the toasting time for a given setting of bar 41 decreases as the ambient temperature rises. A further control of the braking effect is made by moving magnet 55 relative to 54, i.e. towards 54 with increase of ambient temperature by the bending of the bi-metal 68 while this link 65 rocks the magnet carrying lever 63 about its pivot. Compensation for excessive reduction of toasting time may also be done by a shunt mounted against one of the faces of the magnet parallel to 54 to reduce the field strength of the magnet so that the field acting on 54 increases with ambient temperature.

IPC: H03C1/52
Filed: 1929-08-01
Abstract: 335,009. Telefonaktiebolaget L. M. Ericsson. Oct. 1, 1928, [Convention date]. Thermionic detectors and modulating systems. -In a modulating or de-modulating circuit having two valves with push-pull connected grids and parallel connected anodes, the reaction of the unode load upon the control voltage is com. pensated by the transference from the anode circuit to each grid, of a compensating voltage of the same phase and amplitude. The input to the grids 6, 6<1>, is taken from the ends of an impedance 11, the tapping 12 of which is connected to the grid bias battery 10, through a coil 13 coupled to the anode coil 8. By a mathematical treatment it is shown that as a modulating system, the device removes certain harmonic frequencies normaIly produced by the anode load, and the dynamic characteristic of the device is made equivalent to the static characteristic. The device may function to suppress the carrier frequency. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification using screen-grid valves for neutralizing the reaction of the anode load upon the control voltages. This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to electrical pulse generating circuits
Inventor: LYALL JAMES BORLAND
IPC: H03K3/53
Filed: 1957-07-26
Abstract: 843,351. Valve pulse generating circuits. METROPOLITAN-VICKERS ELECTRICAL CO. Ltd. July 31, 1958 [July 26, 1957], No. 23759/57. Class 40(6). In a pulse generator comprising a reservoir circuit charged via an inductance and a rectifier, a discharge tube, triggered under fault conditions, is connected across the inductance so as to reduce the voltage across the inductance. Circuits are shown in which a pulse forming network PFN, charged from a D.C. supply via an inductance L and a rectifier D, is discharged at intervals into a load R by triggering a thyraton or ignition represented by S. The load R may comprise a magnetron oscillator. In Fig. 2, under normal conditions, the peak voltage developed across resistor Rl is less than the hold off bias provided by the potential divider R2, R3. In the event of a breakdown across the load R the supply current increases so that the voltage drop across R1 is sufficient to drive the gaseous or spark tube V into conduction. Tube V, with resistor R4, damps the inductor L and reduces the load voltage. In Fig. 1, (not shown), the right hand end of resistor R4 is connected to the cathode of the rectifier D. Fig. 3 shows a circuit in which protection is initiated by the pulse forming network recharging negatively in consequence of a load circuit breakdown. The reverse voltage is detected by a circuit such as that described in Specification 732,258 which feeds a pulse via a transformer T to trigger the tube V.

Filed: 1956-08-02
Abstract: 813,278. Torpedoes. CLEVITE CORPORATION. Aug. 2, 1956 [Aug 18, 1955], No. 23846/56. Class 9(2) An automatically steered torpedo has a liquid filled chamber 22 in the nose closed by a resilient diaphragm 24 and within the chamber a frame 16 is pivotally suspended to hang vertically for any position of the torpedo, an electro-acoustic transducer 25 being pivoted on the frame. In addition, a spring-biased bellows 36 between the frame and the transducer and responsive to changes in hydrostatic pressure transmitted through the diaphragm to the enclosed liquid controls the position of the transducer. The torpedo is made in separable sections, the cast body, 13 of the nose having two projections 14, 15 (not shown) in which are fixed rocker arms 17 each having at the inner end a knife edge 20 supporting the frame 16. The diaphragm 24 is of neoprene or rubber and is secured to a metal annulus 23 fastened to the body 13 to form a chamber filled with a liquid such as castor oil. Piezoelectric plates 26, which may be Z-cut ammonium dihydrogen phosphate crystal plates arranged in an elliptical pattern, make up the transducer which has a window 27 and a back-plate 28 secured to a bracket 29 pivoted in the frame 16. Frame 16 also carries a bracket 35 in which the corrugated metal bellows 36 is mounted with its free end bearing against a leaf spring 37 attached to the plate 28. A compression spring 38 surrounding the bellows opposes compression of the bellows, which is so arranged that the transducer is orientated at about 3 degrees to the horizontal when the torpedo is in shallow water i.e. when first launched. At greater depths, the increase in pressure on diaphragm 24 causes compression of the bellows, so that the transducer is titled clockwise to direct its beam away from the seabed and avoid unwanted reflections. Conversely, as the torpedo nears the surface the transducer is tilted anti-clockwise to cut out reflections from the surface.
