IPC: F01P11/16
Filed: 1926-11-27
Abstract: 278,209. Schlaich, H. Nov. 27, 1926. Thermometers. - A thermometer for use in connection with the cooling system of an automobile engine is embedded in a mass of metal forming part of, or in direct metallic connection with, the metal of the cylinder so as to be under the joint influence of the cooling medium and of the motor itself. The invention is particularly applicable in connection with motors employing steam-cooling in which case the thermometer provides an indication depending on the constant temperature of the steam and on the variable temperature of the engine. In the form of mounting shown in Fig. 2 a web 13 is provided between the water jacket 3 and cylinder 2 and is formed with a central aperture in which the temperature responsive element 12 is inserted. The element is held in position by a nut 15 and is connected to an indicator on the dashboard &c. Fig. 5 shows one method of arranging the thermometer in an engine in which the head 102 is secured to the cylinder block by bolts 103. In this form one of the bolts is replaced by a bolt 111 having a bore 112 in which the temperatureresponsive element 114 is inserted. The element 114 is provided with a flange 115 on which bears a clamping-nut 116. This Figure shows the element 114 connected by a tube 117 to an indicator 118 on the radiator cap 105. The indicator may, as shown in Fig. 6, comprise a pointer 119 moving over a plate 120 having a part 121 marked " cool," a part 122 marked " stop " and between these a " safe " zone having therein a circular opening 123. The pointer 119 has a corresponding circular enlargement 124 provided with a transparent coloured disc 125. Fig. 7 shows another form of mounting for the thermometer, for use when the cylinder head is secured by nuts passing over studs. One of the nuts is replaced by a nut 127 having a stem 128 provided with an orifice in which the sensitive element 129 is inserted. The element is insulated from the effects of atmospheric temperature by a sleeve 131 of hard rubber &c. Fig. 4 shows a radiator which may be used for a steam-cooling or for a water-cooling system. The inflow and outflow pipes 106, 107 are disposed at the sides of the radiator so that the cooling medium circulates horizontally across the radiator, and also downwardly.

Title: Electronic timepiece
IPC: G04G9/06
Filed: 1974-07-09
Abstract: The watch has a timer (11), a position-dependent switch (22), a timing circuit (23) with a counter, and a flip-flop connected to the output of the counter, as well as a control switch (21), which is connected to the output of the timing circuit, for activating the time display. The switch (22) applies a switching signal (24) whenever the watch assumes a specific position. Upon expiry of a specific time interval from the occurrence of the switching signal, the counter supplies a resetting signal to the flip-flop. After receiving the switching signal (24), the latter generates an activation signal (25) and interrupts the latter upon receipt of the resetting signal. The display (18) indicates the time indication supplied by the timer (11) as long as the control switch (21) maintains the activation signal (25). <IMAGE>

IPC: G01S13/78
Filed: 1967-06-30
Abstract: 1,173,228. Transponders. A. C. COSSOR Ltd. 31 May, 1968 [30 June, 1967], No. 30379/67. Heading H4L. A secondary radar pulse decoder for indicating when first and second interrogating pulses are separated by a predetermined time, comprises means for delaying the first pulse by the predetermined time and coincidence means responsive to the concurrence of the delayed first pulse and the second pulse and to the order in which the pulses are applied to provide an output to trigger a transponder return only when the delayed first pulse and the second pulse are concurrent and a predetermined one of the delayed first pulse and the second pulse commences not later than the start of the other one of the pulses. As shown in Fig. 3, pulses to be decoded are supplied via terminal 31 to a known arrangement of two parallel shift registers 32, 33 supplied with out-of-phase clock pulses from a source 34. After a predetermined delay dependent on the number of stages the outputs of the registers are supplied to a coincidence detector 30 where they may or may not be concurrent with undelayed pulses applied direct to circuit 30. The coincidence detector 30 includes logic circuitry, Figs. 2 or 4 (notshown), to ensure that concurrent pulses give an output only when the delayed first pulse commences before the start of the second pulse. This reduces the effect of jitter, since only when the second pulse has been retarded by jitter and not when it has been advanced, will decoding occur.

Title: A new or improved mechanism for the operation of train stops on railways, railway signalling devices or other apparatus
IPC: B61L3/08
Filed: 1926-12-02
Abstract: 286,362. British Power Railway Signal Co., Ltd., Glenn, S. L., and Pierce, E. E. Dec. 2, 1926. Driving - arrangements. -In a motor-driven mechanism for moving a device from one position to another, the operation of the motor by power supplied to it causes the mechanism, including the motor, to move upwardly through a predetermined distance and when power is cut off the mechanism and the motor move downwards under gravity and restore the driven device to its normal position. The invention is particularly described as applied to an electrically-operated track-side mechanism for stopping trains and the apparatus includes an electric motor and holding mechanism as described in Specification 276.109 and an electric switch having slow and quick-breaking contacts for controlling the motor circuit and indicating circuits. The electric motor, the electromagnetic holding mechanism and a set of gear wheels, including a one-way ratchet-and-pawl drive and a friction-drive, of which the last pinion 3 only is shown in Fig. 1, are enclosed in a casing 2 which is keyed on a shaft 4 rotatable in bearings in a casing 10 which encloses the whole mechanism. The pinion 3 gears with a quadrant 8 which is movable about the shaft 4 its movements being limited by a stop 17 which engages two faces of its lower edge. When power is supplied to the motor, the pinion 3 moves along the rack 8 and the motor casing 2 is moved to the dotted line position shown, rocking the shaft 4 and the train stop arm 12 carried by it.. When the upward limiting position is reached, the holding mechanism as described in Specification 276,109 is energized and prevents reverse rotation of the motor and current is cut off from the motor. When the holding magnet is de-energized, the weight of the motor and associated parts in the casing 2 causes the restoration of the apparatus to the lower position in which the motor casing rests on a spring buffer between the boss 1<a> and the boss 15 on the outer casing. The slight movement provided to the quadrant 8 allows this to be raised and absorb a part at least of the momentum of the moving parts at the end of the downward movement. The weight of the quadrant 8 aids the starting of the motor at the beginning of its upward movement and since the pinion 3 is not raised until the quadrant 8 has been rocked through its permitted angle of motion the motor is started free from load.

Abstract: 1374072 Automatic control of braking BENDIX CORP 28 June 1973 [1 Aug 1972] 30738/73 Heading G3N [Also in Division F2] In an adaptive braking system for a wheeled vehicle three signals, Vw, V w +M and V w -N, where V w  is the wheel speed, are generated, the second Vw + M, and third Vw-N, being at respectively higher and lower voltage levels than the first, Vw, the third signal Vw-N being impressed upon a memory 30, comprising a capacitor, before it decays at an excess we rate, the impressed signal being decayed at a lesser rate than the decay rate of the third signal after the latter exceeds the predetermined rate and until the impressed signal is in a predetermined proportion to the second signal Vw + M whereafter the second signal is impressed on the capacitor and thereafter controls, with the first signal, the braking force. As shown, speed signals from a tachogenerator 20 pass to a scaler 22 producing the three outputs Vw, Vw-N, Vw + M where M and N may be fixed numbers of miles per hour a percentage of speed signal V w  or a combination of both. Output V w  is passed to a comparator 28 and outputs V w -N and V w +M are respectively passed to an acceleration memory update 24 and a deceleration memory update 26 the outputs of which are fed to a memory 30. Memory 30 has an output Vr fed to the comparator 28 and a feedback output fed to a memory decay 32 the latter also receiving signals from the comparator output. The acceleration memory update 24 impresses the third signal into memory 30 as long as the speed signal V w  does not decay at the predetermined excessive rate determined by memory decay 32. If decay becomes excessive memory update 26 becomes effective to impress signal V w +M into memory 30 when signal Vr equals Vw + M, so long as speed Vw continues to decrease. Comparator 28 generates an output when the signal V w  passes signal Vr to actuate a modulator to relieve braking pressure. A circuit is described, Fig. 3 (not shown) for components 22-32.
