Title: Anti-skid device for use in a pressure medium operated wheel brake system
IPC: B60T8/74
Filed: 1976-01-23
Abstract: 1533034 Anti-skid brake control KNORR BREMSE GmbH 23 Jan 1976 [1 Feb 1975] 02755/76 Heading F2F An antiskid device comprises rod 40 to which is attached roller 42 which follows cam track 44 of flywheel 44<1> such that rod 40 is pushed upwards when the rotary deceleration of the vehicle wheel exceeds a first predetermined value causing outlet valve C to vent brake cylinder D if the wheel decleration persist at or above the first predetermined level for a given period of time. If however a second, higher predetermined decleration is exceeded the roller 42 contacts surface 48 of track 44 to cause rod 40 to open a valve 32 resulting in substantially instantaneous venting of brake cylinder D to relieve braking effort. When rod 40 is raised chamber 38 of the device vents through a hollow extension of the rod via chokes 50, 52 and 54. Chambers 38 and 28 are also connected to control chamber 60 and chamber 70 respectively such that once the pressure in chamber 60 has diminished to a certain value piston 62 will be forced upwards to open valve 68 to vent chamber 28 via pipe 72 and chamber 70, causing upward movement of pot-shaped piston 26 to vent chamber 14 of valve C opening valve 10 to vent and thus relieve brake cylinder D. The delay between the initial movement of rod 40 and brake relief is governed by the size of chokes 50, 52 and 54. In the second predetermined position of rod 40 the valve 32 is opened directly by shoulders 56 of rod 40 causing instantaneous venting of chamber 28, raising of pot-shaped piston 26 by pressure in annular chamber 24 and venting of chamber 14 of valve C therethrough. The flywheel mass 44<1> is of the type mounted on a shaft parallel to rod 40, the track 44 being formed by a cut-out from the outer peripheral annular wall of the flywheel mass 44<1> (see Specification 807,177), wheel rotational deceleration causing relative movement between the roller 42 and the flywheel 44<1> around the periphery of the flywheel along track 44.

Abstract: 928,423. Motor vehicle driving gear ; controlling vehicles. JOSEPH LUCAS (INDUSTRIES) Ltd. April 24, 1961 [Jan. 26, 1960; Sept. 21, 1960], Nos. 2760/60 and 32395/60. Classes 79(2) and 79(5) [Also in Group XXIV] In a vehicle transmission wherein an engine driven swash plate type pump supplies fluid to one or more motors for driving the vehicle wheels or tracks, the angularity of the swash plate is adjustable to vary the speed ratio by driver operable means including a lever angularly movable about a fulcrum which can be preset to determine the maximum output from the pump. As shown in Fig. 1, the swash plate 3 is adjustable by a servo cylinder 4 responding to a plunger 5 operated by a cam 7 the angularity of which is controlled from a pedal 15 acting through a link 14, levers 13 and 10 and links 8 and 9. Stops 28 and 29 are provided to limit the movement of pedal 15 in positions for forward and reverse directions of motion corresponding to the maximum forward or reverse speeds of the engine. A catch piece 16 arrests movement of the pedal at a midway position of the cam corresponding to zero angularity of the swash plate-or neutral-to prevent accidental engagement of a reverse drive. The fulcrum 17 of lever 13 is connected to a slide 18 and may be moved by a handle 27 acting through links 25, 24, 23, 21 and 20 so that the movement of the cam 7 can be varied for a given movement of the pedal 15. Since the angular movement of the pedal 15 is limited, the maximum output of the pump can be predetermined. The linkage associated with handle 27 is such that in one extreme position, the swash plate is in a position of zero obliquity. In a modification, Fig. 2, the plunger 5 is connected to a lever 30 to which is connected a cam follower 31 and an L- shaped lever 32 upon which is mounted another cam follower 33, the levers 30 and 32 also being connected by a coil spring 34 so that the followers 31 and 33 are urged into contact with the cam 7. The follower 33 engages a notch in the cam 7 at a point corresponding to the position of zero angularity of the pump swash plate whereby the catch 16 may be omitted.

Abstract: 758,384. Reciprocating pumps. DAIMLERBENZ AKT.-GES. Jan. 29, 1954 [Jan. 29, 1953], No. 2763/54. Class 102(1). [Also in Groups XXIX and XXXI] A system for the servo-operation of several parts 22 ... 26, on a motor vehicle comprises a main reciprocating pump 10, driven by the engine of the vehicle, or the vehicle, supplying pressure fluid directly to the operating motors, the pump piston stroke being adjustable in dependence upon the requirements of the motors and an auxiliary pump of small dimensions driven independently of the engine or vehicle for supplying the servo-system in alternation with the main pump. Fig. 1 shows an arrangement in which a gear pump 28 is driven by an electric motor 29, which may be energised simultaneously with the actuation of the starter switch, and draws from a tank 17 and delivers past a valve 20 to the main 21 ; a by-pass valve 32 limits the pressure delivered by the pump. When the pump 10 is driven, the pressure developed moves the valve 20 and permits supply to the main 21 and at the same time actuates the spring-loaded piston 39 to open the switch 37 and stop the motor 29. In the Figure, a servo-steering mechanism 22, a servo-brake system 23 and other points are supplied by main 21. The pump may be a swash-plate type and the swash-plate is adjusted by a piston subjected to the pressure in the main 21 or the swash-plate may be adjusted by the reaction of the pistons against a spring- loading the swash-plate.

Abstract: 996,277. Telegraphy. DE STAAT DER NEDERLANDEN, TEN DEZE VERTEGENWOORDIGD DOOR DE DIRECTEURGENERAAL DER POSTERIJEN, TELEGRAFIE EN TELEFONIE. June 7, 1963 [June 28, 1962], No. 22771/63. Drawings to Specification. Heading H4P. A two-way telegraph system in which errors are corrected by repetition and alternate blocks of character signals are normally notionally or actually marked differently, reception of an error causes the receiver to be blocked and a warning signal to be returned to the transmitter. A counter at each station indicates the group in which the signals are to be transmitted and received. The counters step each time a block is correctly received. At both master and slave station the warning signal is sent in the group the turn of which is indicated by the local counter. At the master station, if the received warning signal is in (a) the same group as that shown by the counter, the last block transmitted is repeated, or (b) the other group, a warning signal is transmitted in the group shown by the transmitter counter. At the slave station the warning signal (a) if it is not in the same group as that shown by the counter causes repetition of the last block transmitted and (b) if it is in the same group causes the transmission of a warning signal in the group the turn of which it is. Successive blocks are spaced by at least twice the propagation time, and the time between successive blocks may be filled with signals from other stations on other channels.

Title: Active sensor automatic range sweep technique
IPC: G01S17/18
Filed: 1975-01-24
Abstract: 1491055 Optical position-finding BALL BROS RESEARCH CORP 24 Jan 1975 [4 Feb 1974] 3104/75 Heading H4D The Specification describes an electro-optical device comprising an illuminating means, e.g. a laser, pulsed on and off by timing circuitry, an optical receiving means comprising a gated light amplifier which is gated on a discrete time after emission of each pulse from the illuminator so that radiated light from a plurality of range increments is received by the optical receiver within a single integration time of an associated recording or display device, each range increment being illuminated a number of times corresponding to a programmed memory associated with the timing circuitry, which gates on the light amplifier once for every transmitted illuminator pulse. As described, master clock 20 controls timing circuitry 18 (see Fig. 3) which initiates transmitted pulses from illuminating transmitter 12 and a time t i  later, corresponding to the time required for the illumination reflected from objects from within the ith range increment to be received by receiver 14, 16, gates "ON" light amplifier 16 to receive said illumination. Timing circuitry 18 is programmed to gate light amplifier 16 to view the same range increment a progressively increasing successive number of times as the range increases to maximum, where amplifier 16 is gated on after a time T n , to compensate for the reduced level of received illumination at greater ranges whereby all ranges may be displayed at an effectively equivalent brightness on the viewing or recording device. The speed of the complete range sweep is fast enough, e.g. to provide a flicker-free image under real time viewing. In addition, selected ranges may be examined in greater detail by increasing the number of illuminations of the particular range. Certain ranges may, further, be suppressed by jumping past a preselected range. In Fig. 2, when the time period 29 of the complete range sweep has elapsed, pulses 28 from sweep reset decoder 54, Fig. 3, reset the timing circuitry, i.e. address register 46 and counter 32 which is loaded with a preselected number of range movements "A". Memory 48 is programmed according to the number of respective viewings of each range increment required and loads counter 50 with this number for each range increment. Alternatively memory 48 may be programmed to activate skip decoder for certain ranges. The delay in enabling light amplifier 16 is obtained by using master clock pulses 20 to activate counter 36 successively after a transmit pulse whereupon counter 36 counts up to the value set in counter 32, which equality is detected by comparator 34, to activate light amplifier 16, counter 36 being reset by a signal from delay 44, which signal also counts down the number of viewings left in counter 50. At the end of each range sweep memory 48 activates reset decoder 54, to produce range sweep reset pulse 28, Fig. 2C, which resets memory address register back to zero and reloads a binary number A from register 30 into counter 32, for the next range sweep.

Abstract: 824,935. Liquid fuel burners. DORTMUND-HORDER HUTTENUNION A. G. Jan. 31, 1956 [Jan. 31, 1955; May 9, 1955], No. 3135/56. Class 75(1) A burner comprises a chamber 7 to which liquid fuel and a gaseous atomizing medium are admitted a burner tube 11 extending. from the chamber 7, a first conical guide element 9 disposed at the entry to the burner tube and tapering thereto, a second conical guide element 14 disposed in the discharge end of the burner tube and having a rearwardly tapering portion forming an annular exit 16, and a forwardly tapering portion outside the exit, an annular chamber 12 surrounding the burner tube and to which oxygen is admitted at the rear end, a third conical guide element 13 mounted on the forward end of the burner tube and having a rearwardly directed tapering surface and a forwardly directed tapering surface, the latter forming with the tapering end of the annular chamber 12 an annular passage directing a stream of oxygen to intersect the atomized fuel issuing from the exit 16 of the burner tube. The fuel is admitted tangentially through a nozzle 6 and the atomizing medium tangentially and in the same direction of rotation to the chamber 7 and the mixture issues from the chamber 7 through tangential nozzles 8. The annular chamber 12 is surrounded by water jackets 17, 18. In a modified construction the water jackets surround the front part only of the burner and the rear part is heated by steam or by an electrical resistance surrounding the annular chamber 12. The front and rear parts are connected together by a member which allows relative axial movement of the two parts. The tube 11 has external helical ribs which cause the oxygen in the chamber 12 to rotate in the same direction as the mixture in the tube 11. In a further modification Fig. 8 (not shown) the fuel is discharged from nozzles in the end of a fuel tube disposed axially of the burner and is atomized by air flowing in a surrounding tube and caused to rotate by helical ribs on the fuel tube, the pitch of the ribs decreasing towards the fuel discharge nozzles. The atomized fuel then passes through an apertured ring constructed as a turbine wheel having guide blades. The air tube is surrounded by a tube through which oxygen passes and helical ribs on the air tube cause the oxygen to rotate. The front part of the burner is water cooled and the rear part is heated by steam or electricity. In the burner shown in Fig. 12 fuel and air are fed tangentially to the chamber 7 which is connected by passages 43, 44 and a pipe 45 to a pressure gauge M. The conical guide element 9 is mounted on a piston 41 which can be moved by means of a spindle 42 and lever 46 to vary the areas of the slots 8, 8<SP>1</SP> through which the mixture enters the burner tube 11.
