Title: Improvements relating to vehicle window assemblies
IPC: B60J1/17
Filed: 1955-10-13
Abstract: 772,128. Vehicle windows. GENERAL MOTORS CORPORATION. Oct. 13, 1955 [Oct. 25, 1954], No. 29180/55. Class 20(3) A rear quarter drop window 30 for a hardtop sedan type of vehicle which is pillarless above the waistline and therefore must have its entire support for the window located within a window well 32, is mounted on curved guides 46, 58 for vertical movement in a slantwise path into and out of the well 32 formed between laterally spaced inner and outer panels 34, 36 of the door, and is provided with a stabilizer which resists lateral sway of the window in its raised position and comprises a rail 98 which is pivoted to the lower rail of a frame 38 for the window and is slidably engaged by a fixed roller member 102 so that during opening, or closing movement of the window the rail turns about its pivot and slides along the member 102. The stabilizer arm 98 includes a U-shaped channel 100 which slidingly receives the headed roller 102 which is carried by a bolt 104 adjustably secured to a channel 106 extending horizontally along the outer door panel 36 and secured, with rubber pads 108, at its ends to the door edges. A U-shaped channel 110, welded to the upper end of the channel 100, is pivoted by a rivet 112 to a plate 114 which carries an angle plate 116 to form, with the outer face of the plate 114, a channel to interlock with one upper side of the channel 110 when the window is raised and sealed against the rear edge 40 of a front window 42 and against a roof panel 20. Front and rear rollers 74, 76, projecting from the inner side of the lower edge of the window frame, engage the tracks 46, 58, which are mounted by brackets 48, 50 and 60, 62, to the inner door panel 34, a bracket 56, and a lip 68 on the bracket 62, acting as stops for.the bottom rail of the window frame 38 when the window is lowered. Mechanism for moving the window includes a reversible motor 94 which swings an operating arm 84 which is pivoted at one end at 86 to a frame 88 secured to the inner door panel 34 and carries on its free end a roller 82 which slidingly engages a channel 80 secured to the lower rail of the window frame 38. Additional lateral stability of the window in the raised position is achieved by a tongue 120 which is adjustably secured to the front member of the door frame for interlocking engagement, when the window is in its fully open position, with a grooved bracket 128 which is adjustably secured to the forward edge of the window frame 38. During the rearward and downward movement of the window from a fully closed position, the stabilizing arm rotates in a counter-clockwise direction about the pivot 112, disengages the angle plate 116, and slidably pivots about the roller 102, thus following an irregular curvilinear path different from that of the window.

IPC: F02K1/70
Filed: 1968-06-19
Abstract: 1,181,746. Deflecting propulsive gases. ROLLS-ROYCE Ltd. 19 June, 1968, No. 29185/68. Heading B7G. A thrust reverser for a front fan gas turbine engine, or other engine, comprises a plurality of thrust reverser flaps 24, each pivoted about its centre of pressure 25, the pivot pin at 25 being attached to the double walled casing of a duct 16 in which a front fan 17 rotates. The duct 16 is supported by stays 20 extending radially from the upstream portions of an engine casing 11. The flaps 24 may be pivoted about points 25 from an inoperative position in which they merge with the walls of the duct 16, rearward flow of propulsive gases being unimpeded, to an operative position, Fig. 2, in which flow of gases to the rear of duct 16 is impeded and the. propulsive gases are caused to flow radially through gaps 32 as indicated by arrow A and produce forward thrust. The flow of gases through the radially disposed gaps 32 in the casing of the duct 16 is aided by shaped members 36, which members are movable fore and aft between the two walls 26, 27 of the casing 16 and are connected at their rearward ends to flaps 24 by struts 42. The forward ends of members 36 are connected to rams or screw jacks, so that coupled movement of members 36 and flaps 24 is possible. Loss of propulsive gases through gaps 32 when flaps 24 are in inoperative positions is minimized by mating tongues and recesses 44 and 45 and by mating surfaces 34, 33 on the flaps and casing.

Title: Method of protecting transformers, choking coils, switches, motors, generators, and other electrical apparatus
IPC: H02H5/00
Filed: 1927-11-02
Abstract: 280,209. Buchholz, M. Nov. 2, 1926, [Convention date]. Indicators and alarms, application of; protective or safety devices, auxiliary. - Motors, generators and other electrical apparatus are protected against overload &c. by causing the gases of decomposition which are formed to diffuse into a cell with porous walls, the resulting increase or decrease of pressure operating an electric switch which in turn operates a signalling or cutout device &c. Fig. 1 shows the tank of a transformer or switch in the cover of which is fitted a porous cell b communicating with a U-tube containing mercury. Normally the mercury stands as shown, but should gases be evolved in the oil in the tank the pressure in the cell b becomes different owing to diffusion and a contact d<1> or d<2> is engaged by the mercury. Fig. 2 shows a porous plate e fitted into the cover plate of the compensating vessel of a transformer. The variation of pressure in this case operates a metallic diaphragm. g to close a circuit. Specifications 198,936, 242,926, 245,388, 250,004, 250,827. and 251,843, [all in Class 38 (v), Electric switches &c.], are referred to. The Specification as open to inspection under Sect. 91 (3) (a) describes also the following. Fig. 6 (Cancelled) shows an arrangement wherein, to render operation independent of ordinary variations of temperature and pressure, two cells communicate with each other, through a U-tube containing mercury. The gases of decomposition are directed on to the one cell only. The porous cells may be provided with dust jackets. They may also be heated by a resistance or lamp, to prevent the pores from becoming clogged with moisture. To increase the action, a catalytic agent, such as palladium or platinum, may be used inside or outside or in the substance of the cell. The cells may also be filled with impermeable bodies to reduce the space available for gases, thereby increasing speed of action. A cell may also be composed of a number of chambers through which the gases pass successively. The gases may be passed into the cell by a fan or like device. Arrangements are also described for periodically or continuously ventilating the cell. This subject-matter does not appear in the Specification as accepted.

Title: A process and a device for the improvement or alteration of the properties of filaments of meltable, linear high polymers
Inventor: SCHMIDT ACHIM
IPC: D01D11/00
Filed: 1967-06-26
Abstract: 1,124,903. Electrostatically coating polymer filaments. CHEMIEFASERKOMBINAT WILHELM-PIECK-STADT GUBEN VEB. 26 June, 1967, No. 29378/67. Heading B2K. [Also in Divisions B5B and D1L] Filaments of meltable linear high polymers, such as polyamide or polyolefin, are modified after emergence from the spinneret but before they are present in their final state by passing them through an electrical field where there is produced, by spraying one or more materials, an aerosol with a charge opposite to that of the filaments, the aerosol forming a film on the filaments, which film does not penetrate, dissolve in, or chemically combine with the filaments, or which does so partially or completely. The electric field is produced by a direct current generator 1, a voltage being applied to spray nozzles 5 in the high voltage chamber 2. An aerosol is applied through the spray nozzles and acquires a charge opposite to that on the filament. A fine mesh sieve 3 encompassing the filament axis ensures uniform application of the material. Excess solution is run off through a pipe 6 and recirculated to the nozzles through a feed-in pipe 4. Insulators 7 separate the high voltage chambers from the spinneret.

Title: Magnetic memory devices and methods of making them
IPC: H01L27/082
Filed: 1961-08-15
Abstract: 996,978. Magnetic memory stores. RADIO CORPORATION OF AMERICA. Aug. 15, 1961 [Aug. 30, 1960], No. 29468/61. Heading H3B. [Also in Division H1] A magnetic memory unit is constructed by depositing electrically conductive material on both surfaces and in at least one hole which defines an information storage location in a square ferrite sheet, and removing some of the conductive material so as to provide four separate electrically insulated windings, each including conductive material on both sides of the sheet and in the hole or holes. Holes 23 are drilled through insulating ferrite plate 20, e.g. by an electron beam, to define an information storage region 24. The holes, which have a diameter (e.g. one mil.) which is small compared with the thickness (e.g. 10 mils.) of the plate, are filled with conductive material 25 by electroplating or dipping in solder. The conductors are formed by providing a single printed layer on each surface of the plate, extending over the whole storage region and with limbs extending over each edge of the plate to form terminal ends 33. The conductor is then cut (e.g. by an electron beam) between the holes to provide four separate conductors 27, 29 on each surface. In another embodiment a single hole four mils. in diameter is provided in the plate and is filled with conductive material. A printed layer is provided on each surface as before and a cross-shaped aperture 48 is cut out of the material in the hole (Fig. 6). In a further embodiment a cross-shaped hole filled with conductive material is provided in the plate and, after providing printed layers on the surfaces, a circular hole is drilled through the conductive material leaving material in the arms of the cross. The units may be formed into an array (Fig. 9) by mounting them in rows and columns on an insulating substrate with the protruding terminal ends 33 of adjacent units in contact. In a modification units having left-handed and right-handed curved conductors are arranged alternately (Fig. 10, not shown). It is stated that the two embodiments may be combined to reduce cross-talk. Instead of a square ferrite plate a strip may be used, having a plurality of storage regions along its length. A complete memory may also be formed from a single ferrite plate having storage regions arranged in rows and columns. Such a plate preferably has a thin central area containing the storage regions, and relatively thick edges.

Title: Improvements in or relating to regulating devices for refrigerating machines
IPC: F25B3/00
Filed: 1929-09-28
Abstract: 319,796. Brown, Boveri, et Cie, Akt.- Ges. Sept. 29, 1928, [Convention date]. Electrically-actuated valves. -The switch 4 of the driving-motor 24 and the cooling-water valve 13 of a compression refrigerating machine 20 are actuated by an electromagnet 1, and held latched in the working position, or unlatched, by auxiliary electromagnets 9, 25 under the control of a thermostat 18 or other device sensitive to the cooling action of the machine and a device 22 sensitive to the temperature or flow of the cooling-water. A contact 21 is closed by the device 18 when the temperature of the cooling-chamber 19 is at the upper limit, and a contact 23 is closed by the device 22 so long as the cooling-water is at the proper temperature or flow. On closing of the contact 21, assuming the contact 23 to be closed, current flows through contacts 21, 23, the coil 10 of the electromagnet 9, and a contact 12 to the coil 3 of the electromagnet 1. Current also flows through contact 21, the coil 15 of the electromagnet 25, and a contact 17 to the coil 3. The armature 2 is raised and lifts the switch rod 5 and valve rod 14 to start the motor and the flow of cooling water, whereupon the contacts 12, 17 are broken and the armature 2 falls. The switch and valve rods are, however, latched by the members 7, 16 of the smaller electromagnets 9, 25. Should the contact 23 open owing to failure of the necessary cooling-water condition, the electromagnet 9 would be de-energized and release the latch 7, thus opening the motor switch 4 and closing the contact 12. The switch 4 would be closed again as soon as the flow of cooling-water became normal. At the lower limit of temperature of the cooling chamber, the contact 21 is opened and both latches are released to stop the motor and shut the water valve. The contact 23 may be actuated by a device sensitive to the pressure of the water or to the compression pressure, while the device 18 may be sensitive to the evaporator pressure.

Two - stroke - cycle engines; driving gear.- Mixture is drawn into and pre-compressed in a chamber 2 formed between a main and auxiliary piston 3, 5; a spring 8 is the only connection between the two pistons. At the end of the power stroke the exhaust valve 9 is opened and the two pistons separate, mixture entering the chamber 2 through the pistoncontrolled ports 10. Towards the end of the in-stroke the mixture enters the combustion chamber 6 through the valve 7. The cylinder head has a projection 16 to form a recess with the cylinder wall; this acts as a damper on the upward movement of the piston 5. A similar damping action may be, obtained between the two pistons, one being formed with an annular recess to receive a projection on the other. A groove 11 in the cylinder wall allows gases in the chamber 2 to expand towards the end of the outstroke and prevents flow out through the inlet ports 10. A sleeve valve may be used to control the exhaust. The Specification as open to public inspection under Sect. 91 (3) (a) also states that when used on a revolving cylinder engine the springs 8 may be dispensed with. This subject-matter does not appear in the Specification as accepted.
