IPC: B60R16/02
Filed: 2009-12-22
Abstract: A theft prevention structure for control apparatus 12 mounted in a vehicle is provided in which the control apparatus has connectors 21, 22 connected to electrical wiring harnesses and a cover (52, figure 1) which covers a part of at least either electrical wiring harnesses or the control apparatus. The connectors are lever type connectors; the cover 67, 68 forms a connector cover which surrounds connecting portions (16, figure 4) of a connector connecting portion of the control apparatus and connector portions (23, 27) of the lever type connectors; and lean-to portions or flanges 70, 79 projecting into movable ranges of lever portions 25, 29 of the lever type connectors and adapted to block movement of the lever portions are provided for the connector cover. Removal, or at least quick removal, of the cover is difficult and, as operation of the lever type connectors it protects is essential in order to remove the control apparatus, theft of the latter is prevented or made difficult. The control apparatus may be for the control of the engine, transmission, brakes etc. and may be located in the engine compartment of the vehicle.

Abstract: 530,309. Cement. JORGENSEN, M. VOGEL-. March 31, 1939, No. 10177. [Class 22] In adjusting the proportion of ingredients in a mineral so as to obtain a composition suitable for making cement, the mineral is ground and a fraction, the particles of which have about the same size, is removed and subjected to electrostatic separation to remove the unwanted ingredient. The mineral is ground in a high speed mill 1 connected in a closed air circuit with a separator 2, and the fraction not returned to the mill, which may be between 1 to 4 and 1 to 20 of the amount passing through the separator, may be treated in a second separator 3 which removes the finest grains from it, and is then passed between the roll 6a-6f of an electrostatic separator.

Abstract: 1,220,577. Transformers. ENGLISH ELECTRIC CO. Ltd. 1 March, 1968 [6 March, 1967], No. 10369/67. Heading H1T. A transformer core leg comprises a number of packets of laminations of different widths, as in Fig. 6, the laminations in at least the outer two packets 50, 51 on each side of the leg having a plurality of laterally-spaced slots extending between the junctions of the leg with top and bottom yokes so as to reduce the eddy currents induced near these junctions by leakage flux. The laminations may be slotted as in Fig. 4, the unslotted end portion being interleaved with the laminations of one of the yokes. The slots near the sides of the laminations may, however, be more closely spaced than those near the centre. The laminations in each packet may be similar, so that the slots are in alignment, or they may be slotted in different ways to provide greater subdivision of the leg. The ends of the laminations may be mitred. Some of the slots may be filled with a solid non-magnetic electrically insulating material and the unfilled slots used for the circulation of the cooling fluid. The laminations preferably have an additional or more effective electrically insulating coating over their slotted portions to prevent slots being electrically bridged by the adjacent laminations. The core legs may be clamped between a number of non-magnetic electrically insulating plates 16 or the laminations may be held together by banding or bonding. The core is insulated from the windings by a barrier 53.

Abstract: 456,450. Valve circuits for amplifying. WHITE, E. L. C., 32, The Rise, Hilling- don, Middlesex. April 3, 1935, No. 10394. [Class 40 (v)] In a direct-coupled cascade amplifier for a wide range of frequencies in which the anode load impedance and anode impedance of a first valve can together be represented by a pure resistance R in series with an impedance Z, and in which the first valve is coupled to a second valve through an impedance Z<1> and a leak R<1> is provided between the grid and cathode of the second valve, the relationship Z<1>/Z = R<1>/R is maintained. In the case of a tetrode as shown in Fig. 1 the anode impedance of the first valve can be ignored and R = the coupling resistance R3, Z = R2/1+j#C2R2 , Z<1>=R<1>2/1+j#C<1>2R<1>2 and R<1>=R<1>3. Preferably, the leak resistance R<1>3 is much greater than R3. When the first valve is a triode, the calculations must take into account the effect of the anode impedance as a shunt to the anode load impedance. In a modification, Fig. 5 in which additional de-coupling elements R5, C5 are provided, additional coupling elements R5, C<1>5 are provided also. In all cases the time constants C2R2 and C<1>2 R<1>2 are equal and also C2R3 and C<1>2 R13.

Abstract: 568,139. Twisting and winding yarn. BRITISH CELANESE, Ltd. June 28, 1943, No. 10460. Convention date, July 1, 1942. [Class 120 (ii)] A twisting and winding machine for the production of yarn packages in which the thickness of the yarn on the package tapers towards each end of the package, comprises a spindle, means for guiding yarn to said spindle and means for traversing both spindle and guide means to and fro in the direction of the length of the spindle with different frequencies and over distances whose sum is substantially equal to the total length of the package to be wound. A cam 16, driven from the mainshaft through belt, gear and worm mechanism, oscillates a lever 18 which is adjustably connected to a rod 21 at 22, 23 to reciprocate a rod 25 which, in turn, is connected by cables 28, passing over idler pulleys 29, to vertically movable rods 33 carrying the ring rail 4 provided with rings 35 and travellers. The reciprocation of the ring rail is relatively rapid e.g. 5 to 20 strokes per min., and the length of the stroke is the length of the package less one tapered portion. The spindles are also given a vertical reciprocation from the main shaft through a cam 43 driven through reduction gearing 41. This cam reciprocates a rod 45 which through rack and pinion gearing rotates a shaft 51 provided with gears 54 meshing with racks 55 attached to the spindles. The reciprocation of the package is relatively slow, e.g. once in 5 mins., and the stroke is the length of one tapered portion of the package. The chaser motion and the builder motion are arranged to be out of phase so that the ring rail is in different positions each time the spindle reaches its highest point.
