Patent GB-227706-A (GB)
Abstract: 227,706. Schr÷der, E. May 21, 1924. Regulating transformers. -The primary winding of a transformer for resistance welding and heating machines is regulated by varying the magnetic leakage by switching in, stepby-step, the turns of an auxiliary winding b on a limb of the transformer not surrounded by the secondary, and simultaneously cutting out corresponding turns of the principal winding a. In the arrangement shown in Fig. 1<a>, the no-load voltage remains constant, while the working voltage can be regulated in five steps by connecting opposite pairs of contacts 1 - - 5. In a modification, Fig. 2, increased regulation is obtained by so arranging the contacts that the same plug may be used for connecting any pair of opposite contacts or for connecting any contact with the contact lying forwards on backwards in the opposite winding. Further variations may be obtained by providing different numbers of turns in the successive steps of either or both of the windings.

Abstract: 1,200,029. Inertial navigation systems. SINGER GENERAL PRECISION Inc. May 15, 1968 [July 17, 1967], No.23089/68. Heading G1C. An inertial navigation system for a craft comprises a platform 14 having a mounting with only two degrees of freedom i.e. about the eastwest axis E and the vertical axis Z deviations of the platform 14 from a level orientation about a third axis orthogonal to the other two i.e. the northsouth axis - N being determined by comparison in a circuit 104 of the velocity of the craft along the axis E as determined by integration of the output of an accelerometer 42 on the platform and by a Doppler radar equipment 48, the circuit generating electric signals to compensate the operation of the apparatus for deviations of the platform from level orientation about the axis N. The Doppler radar is provided with an antenna 10 carried by a platform 12 having two degrees of freedom about the craft roll and pitch axes. The platform 12 also supports the platform 14 a pick-off 16 giving heading information in terms of the altitude of the craft in relation to the axis N. The platform 14 is stabilized by a two-degree of freedom gyro 40 sensitive to movement about the Z and E axes, torques 28, 38 maintaining the platform aligned in azimuth and level about the axis E respectively in response to signals from the gyro. The platform 12 is maintained level by torque motors 24, 26 acting in response to signals from a level sensor 18. The Doppler radar gives heading and crossheading velocity information for the craft, and by comparison in a resolver 52 with heading information from the platform 14, these velocity signals may be resolved to give velocity components along the axes N and E respectively. The accelerometer 42 is also sensitive to accelerations along the axis N and by integration of this output in a circuit 77, a signal representative of the north-south velocity may be obtained, which by comparison in a circuit 78 with the Doppler radar derived northsouth velocity may be used to determine any misalignment of the gyro 40 spin axis 56 in azimuth the derived error signal being used to correct the gyro alignment and provide automatic gyrocompassing. The system is also corrected for the effects of earth rate and by means of circuits 100, 122, Coriolis acceleration.

Filed: 1939-08-16
Abstract: 530,433. Slag screens. BRITISH THOMSONHOUSTON CO., Ltd. Aug. 16, 1939, No. 23641. Convention date, Aug. 17, 1938. Addition to 464,631. [Class 51 (i)] [Also in Group XXVI] In the mercury boiler described in the parent Specification in which the heating-tubes have portions arranged in groups each comprising several tubes twisted together to form ropes extending across the combustion chamber and serving as slag-screens, the ropes are arranged in the form of catenaries, in order to reduce the stresses set up in them. The boiler comprises combustion and convection chambers formed by lower and upper walls 71, 83 and intermediate walls 72 which have sliding joints 74, 75 and are flexibly supported from beams 77 and posts 76. Liquid mercury is supplied from a drum 79 supported in the intermediate section, and passes down through tubes 86 to heating-tubes 82, 83 which line the front and rear walls of the combustion chamber. The mixture of liquid and vapour passes up through the tubes 82, 83 to headers 84, 85 communicating with the drum. The lower portions of the side-walls of the combustion chamber are lined by heating-tubes 87, 88, which are also supplied with liquid by the down-tubes 86. The intermediate parts 89 of the tubes 87, 88 are twisted together into groups to form a slag-screen, and their upper parts 90, 91 are aligned to form protecting walls around a housing 92 of insulating material located below the drum. The upper ends of the tubes are connected to the drum. A forced circulation is effected by pumps 94, 95 connected in series, to which liquid is supplied through an inlet 101 and also from the drum through a conduit 103. The pumps are driven by a motor 96, the speed of which may be varied in response to changes of operative conditions, as described in Specification 501,200, [Group XXVI]. The pumps deliver liquid through conduits 104, 105 to headers 106, 107 from which it passes down tubes 108, 109 lining the side-walls of the boiler. The tubes then bend upwards, and are grouped in twisted catenary shaped portions 110, 111. They are continued upwards past the side of a housing 114 of heatresisting material located above the drum and containing vapour-discharge conduits 115, 116. At their upper ends, the tubes are connected to the upper ends of inverted heating-tubes 117, which are bent into hairpin shape and are located in the convection chamber. From some of the tubes 117, the liquid is led down by tubes 118, 119, having catenary shaped portions 120, to the drum, and from others by tubes 122, 123 to the headers 84, 85. The drum contains a concentric baffle 125, forming a liquid-vapour separating device. The vapour-discharge conduits 115, 116 are connected to the space inside the baffle.

Title: Improvements in or relating to windscreen wiper systems
IPC: B60S1/08
Filed: 1964-06-08
Abstract: 1,059,644. Control of D.C. motors. TRICO PRODUCTS CORPORATION. June 8, 1964 [June 10, 1963; June 27, 1963], No. 23641/64. Heading H2J. [Also in Division A4] Intermittent operation of a windscreen wiper is provided when contacts 112, 112a, are closed to energize an electric motor 14 driving the wiper blades through gear 62. When projection 66 engages rod 90a during the first cycle of operation, diaphragm 84 and operator 100 are moved to compress spring 91 and open contacts 112, 112a. The wiper motor circuit remains closed however through parking switch 52 until the parking switch is opened by cam 53. The movement of the diaphragm to the right expels air through check valve 128, the controlled bleed through conduit 124 permitting spring 91 to return plunger 90a to a position wherein it is engageable with projection 66. The motor is then re-started. The wiper may be operated continuously by by-passing the timer switch, repetitive operation of the timer switch being prevented by a lost-motion connection between diaphragm 84 and operator 100. In a modification, conduit 124 is connected through a pipe to a metering valve adjustment of which varies the length of the dwell period, Fig. 4 (not shown). Another arrangement provides vacuum hold means for maintaining rod 90a out of engagement with projection 66 during continuous operation. A manual control member comprises a rotatable contact-plate which is moved to one position for continuous operation of the wiper, and, at the same time, chamber 88 is connected to a vacuum source to disengage rod 90a from projection 66. On actuation of the controller to afford intermittent operation, air is admitted to the chamber 88. The length of dwell is adjusted by means of a metering valve forming part of the manual controller, Fig. 5 (not shown). In a further embodiment, a rack-and-pinion is coupled through a Bowden cable with the diaphragm 84 to maintain the rod 90a out of engagement with the projection 66 during continuous operation of the wiper, the rack-and-pinion being mounted on a manual control handle, Fig. 6 (not shown). The projection 66 may be engageable with a lever arm for actuating the rod 90a, air being drawn through a check valve into chamber 86 to check the biasing action of spring 91. When the spring is compressed and tends to return the diaphragm, air is forced out of chamber 86 at a controlled rate. A lost-motion connection may be afforded between actuator 114 and operator 100, Fig. 8 (not shown). The timer switch may be located remote from the wiper motor and actuated by a cam attached to a wiper pivot shaft or an arm connected thereto, Figs. 9, 10 (not shown).
