Patent GB-499919-A (GB)
Title: Improvements in or relating to frying apparatus
IPC: A47J37/12
Filed: 1938-02-18
Abstract: 499,919. Cooking in fat or oil. CHILDS, K. L. Feb. 18, 1938, Nos. 5122 and 5123. Convention dates, March 9, 1937 and Aug. 24, 1937. [Class 28 (i)] [Also in Group XVII] In frying-apparatus, the overflowing of fat or oil due to the foaming caused by steamgeneration when raw wet goods, e.g. potatoes, are placed in the pan, is prevented by a rim 12 which is spaced from the walls of the pan 10 to separate a central cooking space 14 from a surrounding space 16 in which the fat is undisturbed. The foam which passes over the rim, being quickly disrupted by contact with air, falls into the space 16. The top edge of the rim 12 is below the level of the top of the pan, and the lower edge is spaced from the floor of the pan by legs 18 which also space the rim from the pan walls. The rim is formed from a strip of metal, the ends of which are connected by a member 24 forming a socket for holding a thermometer, a gap being left between the ends of the strip to provide a passage through which oil passes to the thermometer. The thermometer has a ring upon its stem which contacts with the top of the member 24 and prevents the thermometer from touching the bottom of the pan. Oil displaced from the space 16 by the disrupted foam, passes into the cooking space 14 through the space at the bottom of the rim. The basket 20 is provided with short legs 22 which support it out of contact with the pan bottom. Heating is effected by a gas burner 32 controlled by known thermostatic means 44, 46. In a modification, the legs 18 are dispensed with, the bottom of the rim being outwardly flared to engage in the angle between the walls and the bottom of the pan which is flat. Circulation between the oil spaces 14, 16 is provided for by passages cut in the flared bottom of the rim, or in the vertical walls of the rim. An inwardly bulged rib runs around the rim to space the basket from the circulation openings, and to provide an oil level indication. The thermometer is of the bi-metallic strip type and is rotatable in the socket which, as in the previous modification, connects the ends of the strip forming the rim.

Title: Semiconductor cooling means
IPC: H01L23/48
Filed: 1973-02-01
Abstract: 1427624 Semi-conductor devices SIEMENS AG 1 Feb 1973 [1 Feb 1972 25 Feb 1972] 5201/73 Heading H1K A disc cell thyristor 2 recessed at 3, 4 is retained by the pressure of coned shoulders 5, 6, of a Cu or Al cooling member 7, 8 receiving developed heat; each member having two longitudinal bores 11, 12 parallel to faces 9, 10 of the thyristor and disposed horizontally or vertically. Thin walled heat tubes 15, 16 of Cu extend through bores 11, 12 and are brazed in for thermal contact; sealedly containing a capillary structure of, e.g. metal gauze 17 saturated with methanol, ethanol, acetone, benzene, or water. The tubes project from both ends of cooling members 7, 8 and carry rectangular air convection cooling plates 18, 19 of, e.g. Al, which are push fitted or welded on the tubes to lie spacedly parallel; their edges being positionally located by plastic members (not shown). Alternatively the tubes may be ribbed for cooling. Securing straps 21, 22 bored at 23, 24 are machined on to cooling member 7 with similar straps on member 8, and are interconnected in pairs by screws and locknuts engaging the bores, or secured by yokes bridging the securing straps. The members 7, 8 effect electrical connections to the thyristor and have tapped bores for terminals, and in operation heat developed in the thyristor is transferred to members 7, 8 to locally evaporate the working fluid, whose vapour flows in the sense of the temperature drop to condense at the outer ends of the tubes 11, 12 from whence the heat of condensation is dissipated by the cooling plates 18, 19. In a modification (Figs. 3, 4, not shown) a thyristor is similarly held between cooling members secured together by external screws and lugs, which have therein continuous longitudinal channels of elongate cross-section. The latter may be respectively oval and rectangular, and therein thin walled heat tubes are brazed, lined with a capillary structure of, e.g. metal gauze impregnated with a working fluid, e.g. benzene, methanol, ethanol, or water. The tubes are sealed and project out of the recesses at each end and carry cooling fins thereupon, and may be fabricated of two or more sealed component tubes in abutting contact. In a further modification (Fig. 5, not shown) the channels in the cooling members have rectangular cross-sections containing correspondingly shaped heat tubes, and the members are resiliently compressed against the flat side of a thyristor by opposed bow springs connected at the ends by screws and nuts. The heat tubes may be shrunk, screwed or brazed into the cooling members. Reference has been directed by the Comptroller to Specification 1,346,157.

Title: Electrical selector for coin chutes in coin-handling and/or coin freed apparatus
IPC: G07D5/00
Filed: 1943-04-08
Abstract: 575,679. Controlling and actuating by sounds. HOVEY, C. E. April 8, 1943, No. 5641. [Class 118 (ii)] [Also in Groups XVIII and XL] Testing by ringing.-An inserted coin passes down a shoot 8 and drops on to a sloping anvil 16 rigidly mounted, and the vibrations of the coin are picked up by a microphone 12, the coin passing to a hopper 20, lined with padding to prevent stray vibrations, and onwards to a conduit 24 having two exits, one blocked by the solenoid 32 which is operated by the vibrations of a proper coin to pass it to a coin box 26, the other 28 to a shoot 30 for discharging spurious coins. A proper coin momentarily opens a contact 52 on entering the coin box in order to reset the electrical selecting circuit. The circuit contains an amplifier valve 36, a sound amplifier 38 and a relay control valve 40. The vibrations of the microphone 12 are applied to valve 36 and a band pass filter 42, of the Wein bridge type is arranged so as to have no potential at the points where it is connected to valves 36 and 38 when energy coupled back from valve 38 is of the same frequency as that to which the bridge is balanced. The output of valve 38 is fed to relay control valve 40 and a part through filter 42 to the cathodes and suppressor grid of valve 36. For a proper coin no bucking current will thus pass, but for a spurious coin the bridge output back to the valve 36 will prevent further amplification by valves 36 and 38. The amplified impulses for a proper coin reaching valve 40 cause the current therefrom to de-energize the normally energized relay 46 and thereby drop its armature to make contact 112 so that relay 48 is energized to pass current through contact 110 to cause solenoid 32 to withdraw its core 34 and free the passage for the proper coin to the coin box 26, the coin on its way opening contact 52 to break contact 110 and reset the solenoid 32 and relays 46 and 48 all of which, as shown at 114, 116 have a separate power supply.

Title: Improvements relating to record-card-controlled statistical machines
Filed: 1929-02-20
Abstract: 306,508. Tauschek, G. Feb. 22, 1928, [Convention date]. Statistical apparatus.-In record-card-controlled statistical machines the printing racks are used to set mechanism which perforates a total or sub-total in a special field of the card controlling the machine. In each column of the card, Fig. 1, a number is represented by a number of holes equal to the number of the digit, columns 9 - - 15 constituting the said special field. The card 1 is read by electrical feelers 3 and operates a magnet 4 for each column a, number of times equal to the digit, thereby raising a printing rack 6 differentially by pawl 5. This rack on its return stroke downwards through gearing 8 correspondingly causes a bar 9 to move over a number of punches 10. At the appropriate time this bar is forced down, by straightening toggles 11, to perforate the card in the special field. 19 and 20 are total and sub-total magnets respectively and contacts 16 are opened as soon as the rack 6 rises from its lowest position. A magnet 13 in series with contacts 16 is used to throw in a clutch 13<a> so that a cam 12 straightens the toggles 11 at the correct time. An electrical contact feeler 15 runs on the unperforated edges of the cards so that only when a card is present is the relay 14 de-energized and the circuit of the magnet 13 completed. When a card having no hole in a controlling column reaches the brushes 3 the corresponding contacts 16 remain closed and circuit 13, 16, 19 (or 20) is closed to energize the magnet 13 and effect perforation of the total or subtotal. 7 are the usual adding wheels.
