Title: Improved control system applicable to the control of a motor vehicle power transmission mechanism
IPC: F16D67/04
Filed: 1957-04-10
Abstract: 861,789. Valves. GENERAL MOTORS CORPORATION. April 10, 1957 [April 30, 1956], No. 15115/60. Divided out of 861,788. Class 135. [Also in Group XXIV] A timing valve 80 for causing gradual increase of fluid pressure in a line 67 for engaging a friction clutch, see Group XXIV, comprises a piston 82 subject to upward piessure from the clutchapply line 67, and to downward pressure of a spring 88 and also by the same clutch-apply pressure 67 reaching the upper face of the piston through a restrictor 95, which delays downward pressure, permitting the piston 82 initially to rise and exhaust the clutch-apply line 67 at 91, such exhaust being gradually cut off by build up of clutch pressure above the piston. Thus, when pressure is applied to the line 67 to engage the clutch by a control valve (see Group XXIV), the clutch engages gradually. When the control valve exhausts the line 67 for clutch release, fluid pressure is rapidly exhausted from above the piston through a check-valve 94 by passing the restrictor 95, and clutch release is rapid.

Title: Improvements in or relating to remote control systems
IPC: H02J13/00
Filed: 1925-06-12
Abstract: 258,012. Automatic Telephone Manufacturing Co., Ltd., and Remington, C. June 12, 1925. Drawings to Specification. Selective distant-control systems; tell-tale apparatus.-Relates to a system for supervising and controlling from a remote point, the operation and condition of a number of apparatus units at a substation. The apparatus units, e.g., circuit breakers and the supervisory lamps are connected to two switches which are located at the substation and control office respectively and are adapted to be rotated in synchronism either due to a change of condition of an apparatus unit or, when it is desired to check the indicated positions of all the units. The contacts of the switch at the substation are marked in accordance with the positions of the units and when in operation. the switch transmits a train of impulses which is characteristic of the positions of all the apparatus units. The impulse train comprises two impulses for each apparatus unit the first impulses being always of the same polarity but the second impulses being of the same or opposite polarity depending upon the position of the units. The impulses are transmitted over two line wires to operate the switch at the control station. The contacts of this switch are connected to relays which control the illumination of the supervisory lamps. Each pair of lamps is controlled by two relays, one of which is operated by the first impulse to control the locking circuit of the second relay which is energized or left de-energized according to the position of the corresponding apparatus unit. The apparatus units at the substation are selected by a constant number of impulses which are transmitted under the control of a step-by-step switch at the control office. The contacts of this switch are, connected to the selecting keys. When a key is operated the switch is marked in such a manner that an impulse train, having an impulse of distinctive character in a position in the train corresponding to the operated-key, is transmitted. The impulses prior to the characteristic impulse operate a switch at the substation to effect selection and the remaining impulses of the train operate a second switch which transmits a check of the selection to the control station only when the switches at the substation are in complementary positions. The system described is identical with that described in Specifications 252,230, 252,231, 258,178 and 258,179 which are referred to.

Title: Method and device for compensating the gyromagnetic effect
IPC: G01R33/025
Filed: 1972-04-04
Abstract: 1341866 Magnetometers COMMISSARIAT A L'ENERGIE ATOMIQUE 4 April 1972 [9 April 1971] 15399/72 Heading G1N The output of a nuclear magnetic resonance magnetometer on board an aircraft is corrected for the gyromagnetic effect due to rate of turn of the aircraft by deriving from the heading control system of the aircraft a signal which is proportional in intensity to the rate of turn of the aircraft and using this signal either to correct the output of the magnetometer taking into account the angle between the yaw axis and the field being measured or to generate a correction field at the magnetometer sensor head. In Fig. 3, a N.M.R. magnetometer 10 of a type having no forbidden axis is mounted in a tail boom of an aircraft with the axis of its sensing winding aligned with the roll axis of the aircraft. Three alternating voltage signals U 1 , U 2  and U 3  are tapped from the heading control system of the aircraft and two direct current voltage signals are derived whose difference is proportional to (U 1 -U 2 )-(U 3 -U 2 ) in value and sign and represents the aircraft heading. A rate of turn signal is formed in differentiating stage 18 and amplified at 19 and 20, amplifier 19 having a low pass filter at its output with a cut-off at 1c/s. The correction current so derived is applied to a pair of coils 24 whose axis is parallel to the yaw axis of the aircraft. Alternatively, the compensating coils can be arranged to retain a vertical orientation. The invention may be applied to magnetometers having a second sensor at a different distance from the magnetic centre of the aircraft to correct for magnetic effects of the aircraft. Compensating coils may be provided for each sensor or only for the field-measuring sensor, making allowance for the transfer function of the automatic compensation installation. Alternative arrangements The velocity of rotation about the field direction may be measured by a sensor constrained to follow said direction, and a correcting signal applied to the output of the magnetometer or to a compensating coil maintained parallel to the field being measured. The velocity of rotation may be measured about three axes fixed with respect earth and a correcting signal applied to the output of the magnetometer or to compensating coils maintained parallel to said three axes.

Title: Improvements in or relating to lacquer-coated metal surfaces
IPC: B32B15/08
Filed: 1955-05-31
Abstract: Metal articles are provided with a hard, adherent multiple-layer coating comprising a pigmented primer in adherent contact with the metal, a layer of undercoat, consisting of lacquer-grade nitrocellulose, 0 to 50 per cent, based on the weight of the nitrocellulose, of a plasticizer therefor, and 0 to 45 per cent of pigment, based on the total weight of nitrocellulose and plasticizer, and a top coat layer of methyl methacrylate lacquer.  The primer may be of either the air-drying or baking type; in examples conventional car-body finishing primers, viz. modified drying oil primers, are used.  The preferred nitrocellulose compositions do not contain any plasticizer, but if one is used dicyclohexyl phthalate or benzyl butyl phthalate is preferred.  Suitable pigments for use in the invention include titanium dioxide, zinc oxide, iron oxide, zinc chromate, carbon black, iron blue, phthalocyanine blue or green, barytes, whiting, talc, china clay, organic maroons, and chromium tetrahydrate.  The top coat may comprise a homopolymer of methyl methacrylate or a copolymer of this substance with a minor proportion of e.g. acrylic and methacrylic acids, alkyl esters of acrylic acid in which the alkyl group contains 1 to 4 carbon atoms, alkyl esters of methacrylic acid of which the alkyl group contains 2 to 4 carbon atoms, vinyl acetate, acrylonitrile or styrene.  In examples, steel car body panels, some treated with a rustproofing composition such as a phosphate coating, are coated by spraying, the drying of the primer and top coats being accelerated by baking, and the nitrocellulose undercoat being omitted over parts of the panels for comparative purposes; in these portions the adhesion of the top coat was poor when fresh, and failed badly after outdoor exposure, whereas it remained adherent where applied over a nitrocellulose undercoat. Specifications 763,158 and 807,895, [both in Group IV (a)], are referred to.
