Title: Improvements in household refrigerators
IPC: F25D17/06
Filed: 1960-03-23
Abstract: 880,675. Refrigerators. GENERAL MOTORS CORPORATION. March 23, 1960 [April 6, 1959], No. 10265/60. Class 29. In a refrigerator the food storage compartment 20 of which is refrigerated by a closed air stream forced over an evaporator disposed outside the compartment, the stream is divided into major and minor sections the former passing through the compartment and the latter being directed into the compartment to cool a meat-storage drawer to a temperature lower than that of the compartment. An evaporator plate 42 is located in an air channel 40 in the rear wall of the compartment 20 and is divided into major and minor vertical parts 84, 86 by a transverse wall 88, 90. A fan 68 withdraws air from beneath a shelf 26 and forces it up through channel part 84, the bulk of it re-entering the top of compartment 20 through aperture 25. A minor part is, however, diverted by wall 127 to flow downwards throughchannel part 86 for further cooling and is directed into the compartment below the shelf 26 through aperture 129. Beneath the shelf are mounted an egg-rack 30, a vegetable drawer 34, and a meat drawer 38 carried on rails 36 beneath the shelf. The drawer is covered by a metal plate 135 and a depending flange 147 on the shelf divides the space between the plate 135 and the shelf into side by side channels communicating at the front. The aperture 129 discharges air into the left-hand channel through which it flows forwards and then rearwards through the righthand channel. The air is then discharged at the rear of the drawer and flows over the outer sides and bottom of the drawer to further cool it. The air is caused to flow around the drawer by a partition 179 beneath the shelf. Plate 135 has apertures 157, 159 so that a small amount of cold air can enter the drawer, the latter having holes 155 in its sides to allow through-flow of air. Apertures 157, 159 are controlled by a valve plate 161 pivoted at 163 to plate 135 and having an operating handle part 165. The fan 68 is controlled by a thermal element in compartment 20. The compressor motor and a fan circulating air over another evaporator cooling air for a freezer compartment are controlled by the temperature of evaporator 42.

Abstract: 467,528. Vehicle lifeguards. ROTH, A. A. April 8, 1936, No. 10319. Convention date, May 24, 1935. [Class 103 (ii)] - A motor-vehicle lifeguard comprises a tray 1 which normally extends horizontally in front of the vehicle and is carried by supports 6, 7, each having projecting parts engaging respectively a rear horizontal slot 15 and a front cam slot 20 in a main supporting bracket 16 so that, on the tray meeting a yieldable obstruction, it is guided automatically into a lower inclined position against the action of a spring 80 whereas, on meeting a fixed obstruction, it is moved upwardly slightly and acts in this position as a bumper. As shown, the tray 1 consists of a tube 2 bent into the form of a closed loop reinforced by rods 3, and is secured by straps 8 to the supports 6, 7 which are formed with lugs 12 connected by a rod 10 and with rearwardly-extending parts carrying studs 14, the ends of the rods 10 and the studs 14 engaging the slots 15, 20 respectively. When the tray moves to its lower operative position, the rod 10 is transferred backwardly and downwardly from pockets 27 in the slots 20 by means of bifurcated guides 21 pivotally mounted on the brackets 16. Rattle of the rod 10 is prevented by a spring-pressed plate 34. To protect the radiator and mudguards an upper bow-shaped guard 47 is secured to the brackets 16 by means of cover-plates 40 formed with halfcollars 49<1> co-operating with half-collars 49 formed at the upper ends of the brackets. To enable the distance travelled by the vehicle after lowering of the guard to be ascertained, a spring-pulled, toothed member 55 for marking the surface of the road is pivotally mounted on one of the brackets 16. In a modified construction, the tray 1 may be folded into an inoperative vertical position, the studs 14 moving out of the slots 15.

Title: Improvements relating to means for measuring torque and/or shaft horse power
Inventor: MCKENZIE ARCHIBALD BATHGATE
IPC: G01L3/14
Filed: 1953-03-19
Abstract: 723,674. Dynamometers. ROLLS-ROYCE, Ltd. March 19, 1953 [April 24, 1952], No. 10388/52. Class 106 (2). A dynamometer for measuring torque or shaft horse-power, comprises a coupling with centrifugally-displaceable masses arranged to be displaced radially in dependence on the rotational speed, and so that such radial displacement is in opposite sense to that of the torque transmitted between the coupling members, and means to measure the angular relationship between the parts of the coupling. The apparatus comprises two flanges 12, 13 fastened to the two portions of the shaft 11, 10. The flanges are coupled by two linkages comprising a link 14 pivoted at 15 in the flange 13 and a link 16 pivoted at 17 in the flange 12. The links 14, 16 are interconnected at their ends by a pivot pin 18 in the form of a stud threaded in the end of the link 14 and engaging in a journal bearing in the end of the link 16. The pivot pin 18 supports a mass 19. The masses tend to be displaced radially outwardly by centrifugal action when the assembly is rotating and thus a couple is applied between the shaft parts 10, 11 opposing the torque being transmitted between the shaft parts 10, 11. The flange 12 is formed with an axially extending portion 21, the external surface of which has inscribed thereon an angular scale and the peripheral edge of the flange 13 has inscribed thereon a pointer which moves along the scale to permit measurement of the angular relationship of the shaft part 10 with respect to the shaft part 11. The coupling mechanism is enclosed in a casing 22 provided with a viewing window 20 through which a beam of light may be projected from a source (not shown) which is switched on and off with the rotation of the shaft part 11. Thus the scale and pointer may be observed stroboscopically by viewing, for example, the scale through a telescope. A mathematical treatment of the apparatus is also given.

Filed: 1950-04-28
Abstract: 678,971. Discharge apparatus. HILGER & WATTS, Ltd. April 30, 1951 [April 28, 1950], No. 10559/50. Addition to 652,702. Class 39 (i). The method of sealing a window over an aperture in a vacuum tube in which the window is cemented in a frame of flexible metal foil which is cemented to the tube, so that the window may expand independently of the tube envelope, as described in the parent Specification, is modified for use with thick flat or lens-like windows. In Fig. 2 the sealing ring 3 of foil is cemented to the tube envelope 1 and the hemispherical window 6. An annular groove 4 allows play during expansion and prevents penetration of cement between parts 1 and 6; diametral grooves 5 enable groove 4 to be evacuated. A suitable cement is silver chloride, but as this corrodes glass and other substances, a protective layer of metallic silver may first be burnt on to the surfaces to be cemented.

Title: Electronic teleprinter transmitting and receiving system
IPC: H04L25/45
Filed: 1965-03-12
Abstract: 1,093,674. Telegraphy. CREED & CO. Ltd. March 12, 1965 [March 14, 1964], No. 10572/65. Heading H4P. A telegraph apparatus used both for transmission and for reception over a single line comprises, common to receiver and transmitter, a pulse generator and an arrangement for converting serial data to parallel and vice versa. The transistor circuitry is generally similar to that described in Specification 1,019,828. In the transmitting mode, parallel data from a keyboard passes to stores from which the data is read serially under control of sequential clock pulses from a distributor. The signal actually transmitted, which may differ from that stored due, for example, to a line break, replaces the signal in the store. The store is then read out to a printer monitor. In the event of a line fault the monitor prints the wrong character or, if the Start bit is mutilated, no character. A repeat key permits retransmission of the stored character. The receiver is inhibited during transmission, and vice versa. In the receiving mode, serial data from the common line is distributed sequentially to the stores and from thence read out to the printer.
Patent GB-542137-A (GB)
Title: Method of adjusting a tuned earthing reactance and means for facilitating tuning
IPC: H02H9/08
Filed: 1940-06-21
Abstract: 542,137. Frequency measurements. ENGLISH ELECTRIC CO., Ltd., and AYRES, W. E. M. June 21, 1940, No. 10676. [Class 37] A reactance coil is tuned while it is connected between the neutral point of a polyphase network and earth by injecting into the coil circuit a test voltage alternating or fluctuating at adjustable and known frequency which is varied until it is equal to the normal frequency of supply as indicated by a maximum reading of an ammeter in the coil circuit. The reactance coil 1 on a core 1a is connected between earth and the neutral point 2 of a polyphase system. A gramophone or like small motor 3 drives a rotary commutator 4 or interrupter for periodically interrupting the current from a source of steady voltage. The commutator and voltage source are connected in series with an additional winding 1b on the reactance which thus functions as the primary of a transformer. A stroboscopic disc 5 viewed by the light of a lamp 6 on a 50 period A.C. supply enables the speed of the motor 5 to be adjusted to a predetermined value. Alternatively the motor 3 may drive a standard form of make and break contact, or an electromagnetically vibrated interrupter may be employed. In carrying out the test, the speed of the motor 3 is varied until resonance is indicated by the passage of maximum current through an ammeter 7. According to whether the frequency is above or below the correct value, as indicated by the speed of the motor 3 being above or below its standard value, it can be seen in .which direction the tuning varies from the correct value. The reactance 1 is then varied and the test repeated until resonance occurs at the correct frequency, as indicated by the stationary appearance of the stroboscopic disc 5.

Filed: 1959-03-31
Abstract: 924,086. Spinning and finishing yarns; woven fabrics. E. I. DU PONT DE NEMOURS & CO. March 31, 1959 [April 14, 1958; March 13, 1959], No. 10924/59. Drawings to Specification. Classes 74 (2) and 120 (3). Composite e.g. cored, yarn of varying denier is produced by feeding at least two groups of filaments e.g. multifilamentary yarns, simultaneously through a turbulent fluid e.g. air which may be heated or steam, zone at such different rates of feed that the extensibility factor i.e. the sum of the increase in length required to straighten the filament without stretching it and the elongation at break of the filament, of one group is higher than that of another group and stretching the resultant composite assembly of filaments, by withdrawal from the zone at a speed predetermined in relation to the feed speeds of the separate groups thereto or at a subsequent stage, so that the filaments of the first group break to form at random intervals along the length of the yarn distinct bundles of discontinuous filaments interentangled with the filaments of the other group (which may constitute a core). The groups may comprise filaments of nylon and rayon, nylon with acrylic, polyethylene terephthalate with rayon, acetate or acrylic, acrylic with rayon or acetate, or nylon with silk or glass. The turbulent zone may be provided in a jet such as described in Specifications 732,929, 842,742, 905,895 or U.S.A. Specification 2,852,906. The intertanglement of the bundles may be consolidated by twisting, as effected by a spinning frame or downtwister or by passage through a " wrapping " jet, such as described in Specifications 871,112 and 924,089, producing a fluid vortex or zone of " fluid torque " which may cause opposed and/or superimposed twist effects in the yarn, or by chemical treatment such as sizing or plasticizing with heat or solvent. Fluid pressure, filament or yarn tension, feed and/or withdrawal speeds may be varied or rendered intermittent in application to achieve different and/or varying loop, slub, denier or bulk effects. The yarn may be produced continuously with other processes e.g. twisting, drawing, back-winding. Composite slub yarn may be woven into a plain-weave fabric e.g. with a warp of multifilament polyester yarn.

Title: Improvements in or relating to the extrusion of metal sheaths for electric cables
IPC: B21C23/26
Filed: 1961-03-27
Abstract: 903,207. Extruding cable sheaths. PIRELLI S.p.a. March 27, 1961 [April 11, 1960], No. 11041/61. Class 83 (4). A cable sheath 3 is formed by supplying molten metal, particularly aluminium, to an extrusion nozzle 1, 2 under atmospheric pressure, applying to the sheath already extruded on intermittent tractive force in an axial direction away from the nozzle so that the extrusion proceeds in steps, and cooling the molten metal in the vicinity of the nozzle. The molten aluminium is fed by gravity at atmospheric pressure into chamber 4 where its temperature is maintained by a heater 5. A cooling fluid is circulated through chamber 6 surrounding the nozzle and a low melting point alloy of lead, bismuth cadmium and/or tin, which has a lower melting point than the extrusion metal, is fed from a reservoir 9 by a pump 10 to a groove 12 surrounding the extruded sheath 3. This alloy reduces friction in the nozzle and is subsequently collected in a funnel 13 leading to the reservoir. A fluid such as water is sprayed on to the extruded sheath from nozzle 16. The intermittent tractive force is applied to the sheath by projections 19 of hard rubber on contra-rotating rollers 17, 18, Fig. 2, which are carried by levers 22, 23 adjusted by a screw 26. The number and circumferential length of the projections may be varied and the speed of the rollers may be adjusted. Alternatively, the tractive force may be applied by fluid pressure reciprocated jaws. Finally, the sheath is reduced in diameter and into contact with the cable core by a die or rolls.
