IPC: B60G17/027
Filed: 1963-09-16
Abstract: 1,073,186. Vehicle suspensions. STANDARD MOTOR CO. Ltd. Sept. 15, 1964 [Sept. 16, 1963], No. 36321/63. Heading B7D. A motor vehicle suspension comprises transverse links 13, 14 and a coil spring 20 extending between cups 22 and 23 attached respectively to the chassis and a link 25 pivoted to the lower arm 14 at 26. An hydraulic piston and cylinder 27 is pivoted at 24 to the link 25 and at 17 to the vehicle and is connected in series with a pump, pressure accumulator and control valve (Fig. 8, not shown). The control valve may be actuated by either of the pivots 17 or 18 of the suspension in response to changes of load whereby the suspension height is restored and, by virtue of the changed attitude of the link 25, the stiffness of the spring is changed. The pivot 18 may be the actuating arm of an hydraulic damper or an hydraulic damper may be incorporated within the spring (Fig. 7, not shown). The hydraulic damper may have, in addition to its normal function, a pumping action whereby the accumulator is charged. Two or more suspension units may be incorporated in parallel arrangement with one pump and accumulator (Fig. 9, not shown). In a modification, Fig. 3, a suspension comprises a trailing arm 31 and a coil spring 20, the lower support of which is pivoted upon an arm 35 pivoted to the trailing arm 31 at 36 and acted upon by an hydraulic piston and cylinder 27 pivoted to the vehicle at 37. The pivot 32 of the trailing arm or the pivot 27 of the piston and cylinder may actuate the control valve.

A photocell has reflecting inner surfaces covered with a transparent photosensitive layer M ; light enters through a lens L in an aperture X, falling on an object F in another aperture, from which it is reflected back into the cell. The cell U is so shaped, as for example the spherical segment shown, that light reflected from F is repeatedly reflected within the cell, thus repeatedly passing through the photolayer M. The anode is a series of collector wires A. The object F may itself form part of the cell wall, or may be brought up close to a window.

Title: Electrostatic developing apparatus and method
IPC: G03G15/09
Filed: 1964-09-09
Abstract: 1,076,595. Electro-photographic processes. ADDRESSOGRAPH-MULTIGRAPH CORPORATION. Sept. 9, 1964 [Sept. 10, 1963], No. 36961/64. Heading G2H. In a process for developing an electrostatic image, toner particles are repelled from discharged areas by a positive corona discharge directed at the rear of an image bearing element, while developer is applied to the front of the element. As shown, a sheet 12 of paper having a photo-conductive insulating layer bearing a charge image on its underside is fed from a sensitizing and exposing section of a copying apparatus to a developing section. Positively charged toner particles are carried on a magnetic brush, created, around a rotating drum 44, by a permanent magnet 46. The developer mix is fed to the drum by members 40 and 42 and removed from it by member 48. A wire 28 is mounted between insulators 82 on a guide member 52, and is maintained at a positive potential of 4-6, 000 volts. Drum 44 is made of conductive material and is at ground potential. The corona discharge produces a microamp current from the drum to ground. A permanent magnet 98 removes iron particles which have been carried on to the back of sheet 12. The sheet is fed out of the developing section by nap surfaced rollers 54 and 56. When used in reversal printing, the corona discharge enables the toner to be evenly applied to the non-image areas and prevents the iron particles from being retained on the image areas.

Abstract: 1518019 Temperature control ROBERT BOSCH GmbH 10 Sept 1976 [11 Sept 1975] 37531/76 Heading G3R Two temperature sensors 45, 54 - which are respectively located upstream and downstream of the heater in a circulating-water heating installation, Fig. 1 (not shown) - effect switching of a signal generator 43 if and only if the temperature difference exceeds a threshold value. The generator output, once switched, provides an oscillatory output whose frequency varies with the temperature difference. This is used to effect progressive adjustment of an output element 33 whose setting determines the heat input. The output response may be independent of or dependent on the ambient temperature sensed at 49, depending on the state of a switch 48. In Fig. 3 (not shown), the switching transistor 55 of Fig. 2 is replaced by a diode and the ambient temperaturesensing arrangement is more elaborate than in Fig. 2.

Abstract: 850,719. Speed responsive electric switches. GAYLORD PRODUCTS Inc. Nov. 21, 1958, No. 37593/58. Class 38 (5). A speed responsive switch for e.g. an anticreep device in an automotive fluid transmission has two switches with operating arms 14, 15 rocked alternately by projections 10 on a rotating member 9, the arms extending into a body of liquid 25 the viscosity of which prevents the arms from moving to the switch closed position when a predetermined speed of actuation is reached. As shown the arms 14, 15 are grounded through their pivots and the case 6 of the device and the other pole of each switch is a plate 20 on which the arms rest when not displaced. As both switches are in parallel the circuit will not be broken until the time for return of the arms is too small for the arms to contact the plate 20. In a modification (not shown) snap action switches having operating arms rocked by a cam are used.

Abstract: 956,212. Films. NATIONAL DISTILLERS & CHEMICAL CORPORATION. Oct. 5, 1962 [Oct. 17, 1961], No. 37852/62. Heading B5B. A flat molten web of thermoplastic material is extruded at 450-550 F., passed downwards through a quench bath containing 7 to 10 inches depth of quench liquid at 140-180 F., and then drawn through a casting zone, contiguous with the quench bath, wherein the web is compressed between at least two rotating cylinders, at least one of which is chilled to 50-70 F., the web being withdrawn from the casting zone in intimate contact with one of the cylinders through an arc of at least 90 degrees. Quench liquid e.g. water, is continuously introduced at a low level in the bath and continuously withdrawn at a higher level to maintain a flow of 10-30 gallons per minute. The area of the exposed surface of the liquid is 0.5 to 1 inch times 1 inch plus the width of the web. Preferably, quench liquid is withdrawn at the surface of the bath by overflow, and also at an intermediate level by a weir gate. In one embodiment (Fig. 1) a film 2 extruded from 1 is annealed by passing into heated quench liquid 3 contained in a tank formed by side walls 4, end walls 5 and a bottom comprising casting rolls 6 and 7. The rolls, rotating in opposite directions, are adjustable to provide a central orifice through which the film is pulled by rolls 24 and 25. Rolls 6 and 25 are chilled by heat-exchange liquid passing through hollow shafts 8 and 27, respectively. Sealing between walls and rolls 6 and 7 may be effected by a felted packing material 9. Quench liquid 3 is supplied from heat exchange system (not shown) via conduits 11 and 12. Quench liquid is withdrawn via conduits 13 and 14 in communication with overflow troughs 15 and 16. Conduits 13 and 14 discharge into drain trough 17 which partially encloses roll 7. Conduit 18 removes quench liquid to heat exchange or drain. The overflow troughs define a slot between their inner edges through which the molten web is introduced, and are provided with flanges 19 and 20 and a series of openings 21, permitting escape of quench liquid. Constant level and overflow rate is also maintained by sliding weir gate 23 discharging into trough 17. Idler roll 24 maintains the quenched and cast web in contact with roll 6 over at least 90 degrees of its surface. The restricted exposed surface area of quench liquid, defined by end walls 5 and inner edges of troughs 15 and 16, suppresses turbulence and localized boiling.

Synthetic textile fibres of spoolable length are treated by passing them through a zone at atmospheric pressure between at least one pair of electrodes to which is applied an alternating voltage of adjustable intensity and frequency to cause an electrical discharge to pass through the fibres therein to form a number of minute passages in the fibres and roughen their surfaces. The fibres may be treated before or after being stretched. The alternating voltage is preferably sinusoidal. As disclosed one of the electrodes of the or each pair is a rotatable roller over and in contact with which the fibres are caused to travel, while the other electrode is a fixed curved metallic plate which is spaced from and partially surrounds the roller. The fibres may be passed through a heating zone before passing through the electrical treatment zone. Means may be provided for adjusting the distance between the electrodes of the or each pair.
