Inventor: BRADSHAW GRANVILLE EASTWOOD
IPC: F02M7/10
Filed: 1916-08-30
Abstract: 111,681. Bradshaw, G. E. Aug. 30, 1916. Spray carburettors.-A carburettor has two choke tubes C, F so arranged that the tube C directs a stream of air into the tube F, thereby increasing the atr pressure at the jet G and preventing excessive flow of fuel at high speeds. A slowrunning tube H extends from the tube F to a point ncar the throttle-valve, so that, at low speeds, almost all of the incoming air passes the jet G. An adjustable fuel valve I is arranged in the tube H. When the carburettor is flooded for starting, petrol squirts from the jet into the tube H, where it is retained by capillary attraction. The tubes C, F mav be adjustable with respect to one another and with respect to their distances from the throttle valve. The jet G is inclined at an angle of fortyfive degrees, and the float chamber A is pivoted to the jet boss M in such a manner that the tube C can be arranged either vertically or horizontally.

Coating bakers' and confectioners' goods; confectionery or sweetmeats; ice-cream preparations. -A core of ice-cream, sherbet, sorbet, ice or other material congealed by refrigeration is dipped into chocolate or like material which constitutes a form-retaining casing, the confection being wrapped in waxed paper and foil. The cores are formed by moulding and freezing a block which is divided by a knife, the cores being then returned to the refrigerator. Forty parts of butter, containing twelve per cent of milk solids and three per cent of butter, are mixed with six parts of cocoa-butter and one part of bitter chocolate liquor to form the coating-material, which is melted at a temperature below 115‹ F. and cooled to 86‹-92‹ F., at which temperature it is used for dipping. The cores are impaled on hook-shaped members, having shanks to facilitate handling, are dipped, withdrawn and allowed to harden. The hole formed by the hook is filled by a drop of molten chocolate or by manipulation of the shell with the fingers. An electrically-heated or water-jacketed copper, tin lined vessel is used for heating the coating material. The confections are returned to the refrigerator after dipping and after wrapping. The confections may having inner and outer coatings with the same or different flavours, and the inner coating may be gelatinous, or the cores may rest on a chocolate coated wafer or a slab of chocolate and a coating applied over both.

Abstract: 548,814. Electric toasting apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 23, 1941, No. 12325. Convention date, Sept. 26, 1940. [Class 39 (iii)] [Also in Group VI] In an electric toaster in which the heating is time-controlled and the toast is then automatically ejected, a hand-operated latch is provided whereby the movement of the toast holder is limited to that necessary to cut off the current and the toast is kept warm by residual heat in the heating compartment. Each toasting chamber is provided with heaters 14 and a vertically moving bread-carrying rack 15 secured to a carriage 16 movable along a rod 17 and pressed upward to the non-toasting position by a spring 18. A handle 20, 21 is carried by a bracket 19 pivotally mounted on the carriage 16, and a resilient latch 22 is also secured at one end to the bracket 19 so that it snaps under a catch 23 to retain the rack 15 in its lower position. The catch 23 is formed on a pivoted lever 24 which may be moved to release the latch by means of a timing device 26 which is wound when the carriage 16 is depressed. After a predetermined interval a portion of the winding rack 26 engages a cam 27 which moves the lever 24. A resilient contact arm 28 mounted on the carriage 16 engages fixed contacts 30 to energize the heaters when the carriage is in its lowest position. The mechanism for retaining the toast in the heating chamber to keep it warm comprises a lever 31 pivoted at 32 and carrying an upwardly projecting arm 33 with catch 34, which engages the free end of the latch 22 to limit further upward movement of the carriage 16 beyond that necessary to deenergize the heaters. The catch 34 may be manually set by means of an extending bracket 35 with arm 36 which co-operates with the hand lever 37, so that when the lever is depressed the catch 34 lies in the path of the latch 22, and when it is raised the catch 34 is moved out of that path. An adjusting lever 45 for the timing device 26 is provided. To release the toast which is retained in the heating compartment the handle 21 is moved slightly upward whereby the bracket 19 pivots slightly relatively to the carriage 16 and allows the latch 34 to release the bar 22. If automatic ejection of the toast is desired, the lever 37 is set in its upper position. Specification 444,736 is referred to.

Title: Improvements in or relating to alternating current electrical torque devices such as measuring or recording instruments or relays
IPC: G01R11/02
Filed: 1930-04-23
Abstract: 353,083. Induction motors. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and BARRELL, F., of General Electric Co., Witton, Birmingham. April 23, 1930, No. 12601. [Class 35.] A magnetic system ener gized from a single-phas supply is arranged to pro duce two fluxes displace( in phase from one another and is provided with a magnetic path common to both these fluxes wherein a third resultant flux is produced displaced in phase from both component fluxes, the three fluxes acting at different pole faces. Such a magnetic system is applicable to single-phase torque devices of the induction type. The Figure shows an induction disc type relay having an E-shaped laminated magnet core 5 above the disc 1 co-operating with a laminated magnetic member 9 below the disc. On one outer limb 6 is a winding 10<1>, connected to supply terminals 11, 12, and also a winding 13 connected in series with a winding 14 on the other outer limb 8. Due to the energizing winding 10 an alternating flux is produced in the magnetic circuit comprising the limb 6, the central limb 7, and the member 9. This flux induces a current in the winding 13, which current also flows in the winding 14, thereby producing a flux in the magnetic circuit comprising the limbs 8, 7 and the member 9, this flux being displaced in phase from that in the limb 6. The flux in the central limb 7 is the vectorial sum of that in the limbs 6, 8 and is out of phase with both these fluxes. The windings 10, 13, 14 may be so proportioned that the fluxes in the limbs 6, 7, 8 are equal in magnitude but displaced in phase by 120‹ from each other, giving rise to a uniform rotating field and therefore a constant torque on the disc 1.

Filed: 1919-05-24
Abstract: 134,497. Regnauld de Bellescize, H. J. J. M. de. Jan. 22, 1919, [Convention date]. Duplex wireless signalling.-In duplex wireless systems of the kind in which a complete station comprises a transmitting station and one or more associated receiving sub-stations., the signals are received or recorded by an operator at the transmitting station, being transmitted thereto by telephonic lines connected to the receiving circuits. Means are provided for diminishing the effect of the adjacent wave transmission on the telephone lines, and for preventing such effects from disturbing the receiving-apparatus. As shown in Fig. 2, the receiving sub-station B comprises an aerial D, receiving-apparatus E, and a device K for coupling the detector or like circuit to the line F<1>, which at the opposite end is connected to a receiver or recorder G', placed at the transmitting station A near the key M. A number of receiving sub-stations may be connected to the transmitting-station and also to a central station. The lines F<1> are buried for part of their length near the stations in order to diminish the effect thereon of the waves transmitted from the aerial at station A, and the two wires are crossed at intervals to diminish inductive effects. When a transformer is employed for connecting the line F<1> to the detector circuit, the line coil is earthed so as to reduce its average potential, and the earthing-point is so chosen that the disturbing currents neutralize each other. Alternatively, the detector circuit may include an electro-magnet P, Fig. 6, vibrating a diaphragm Q which transmits the signals acoustically to a microphone S in the line F. The metallic chamber enclosing the receiving apparatus has a gauze window R to allow the signals to pass to the microphone. In another form, the diaphragm Q is outside the metal chamber and operates the microphone directly, the gauze R being replaced by a thin sheet of non-magnetic metal. Relays may be inserted on the line F. Specification 136,524 is referred to.
