Abstract: 642,440. Clocks. WEBER, M. Dec. 10, 1947, No. 32574. [Class 139] An electric alarm clock has an alarm contacting device comprising two concentric stationary insulated rings connected in the alarm circuit, a contact member which moves between said rings to form a connection therebetween and thereby close the alarm circuit, a slidable member carrying the contact member, the alarm hand, and a pin, displaceably mounted on the hour-hand spindle and urged by a spring against a notched ring carried on the hour-hand spindle whereby when the notch of the ring comes opposite the pin the slidable member can move axially in such a manner as to bring the contact member against the concentric rings and thereby complete the alarm circuit. The seconds, minutes and hours shafts 1, 3 and 5 respectively are co-axial, the seconds shaft 1 being driven by a synchronous motor. The reduction gearing between the shafts 1 and 3 comprises a planet wheel 14 rotatable on a spindle 13 carried by a bracket 12 mounted on the shaft 1 and meshing with two sun wheels 7 and 11 one of which 7 is carried by the minute shaft 3 and the other of which is carried by a sleeve 9 normally held against rotation by the action of a friction disc 22 and a spring disc 23. The hour shaft 5 is driven through similar gearing comprising planet wheel 16 rotatable on a spindle 15 carried by the minute sun wheel 7 and two sun wheels 8 and 10. The sun wheels 10, 11 may be rotated for handsetting. Alarm mechanism. A fixed insulating plate 24 carries two concentric contact rings 26, 28 connected by conductors to screw terminals 30, 31 which are in circuit with an electric alarm device. A wedge contact 43 carried by a settable wheel 41 axially movable on the hour shaft 5 moves between the rings 26, 28 to effect closure of the alarm circuit when a pin 40 carried by the wheel 41 coincides with a notch 37 in a disc 35 fixed to the hour shaft 5.

Title: Noise checking apparatus for interengaging gears
IPC: G01M13/02
Filed: 1974-07-24
Abstract: 1463345 Measuring gear noise WERKZEUGMASCHINENFABRIK OERLIKONBUHRLE AG 24 July 1974 [31 July 1973]  32604/74 Heading G1G The noise generated by meshing gears supported on shafts in hydrostatic bearings is checked by measuring the noise occurring in the bearing fluid. The gears are displaceable in the direction of their axes of rotation and the noise measurement is made as a function of this displacement for a given tooth meshing frequency and a given torque. In the apparatus shown the gears 12, 13 are carried by shafts 10, 11 in hydrostatic axial bearings 18, 19, 20, 21 and radial bearings 14, 15, 16, 17. A hydraulic system including displacement sensors 40, 45 and servovalves 32, 43 enables the axial positions of the shafts to be set (by control 50) then automatically maintained. The bearing fluid noise is converted to an electrical signal by a differential pressure transducer 24 coupled to oil pockets 59, 60. This signal is filtered at 48 then recorded at 49 as a function of the set position of shaft 11. The set position giving minimum noise is determined by differentiating the recorded signal at 53 and detecting at 54 the null in the differentiated signal. Evaluation unit 55 can mark gear 13 to indicate this minimum-noise setting. Comparators 51, 52 detect whether the noise is above a permissible maximum or not, for forward and reverse running of the gears. A servo-loop including tachometer 35, 36 enables the tooth meshing frequency to be set and maintained. A brake 47 provides a controllable torque.

Title: Improvements in or relating to fluid pressure braking systems
IPC: B60T11/18
Filed: 1931-11-28
Abstract: 385,410. Fluid-pressure brakes. BOUGHTON, E. B., EMMOTT, W., and BROCK, D. T., (trading as AUTOMOTIVE PRODUCTS CO.), Brock House, Langham Street, London. Nov. 28, 1931, No. 33054. [Class 103 (i).] In a hydraulic vehicle brake having manually operated low and high pressure pistons in a master cylinder unit 56 for taking up slack and applying pressure respectively and a valve automatically rendering inoperative the low pressure piston and rendering operative the high pressure piston when the slack in the system is taken up, an operative connection of a source of power with the master cylinder is controlled by a speed control of the vehicle. In one modification the speed control is the brake pedal which has a tread mounted on a slidable plunger adapted to actuate by means of Bowden wire the valve of a fluid pressure bellows connected to the brake pedal. In a further modification the accelerator pedal 72 when released is adapted to connect a brake cylinder 51 to a source of power, pipe 71, by means of a valve 58, and thus operate the pedal 54 with sufficient power to take up slack in the brake transmission by means of the low pressure cylinder of the unit 56. When the pedal 54 is then depressed by foot pressure for normal braking this pressure is just sufficient to cause the usual change-over valve of the unit 56 to function and allow the brake cylinder pressure to be applied to the brakes through the increased leverage provided by the high pressure cylinder of this unit 56. Greater force is applied to the pedal 54 by the foot for severe braking. To release the brakes when the pedal is released a valve 59 is provided in the brake cylinder supply pipe 69, 70 adapted to be opened when the pedal 54 approaches release position by a cam 79 on the pedal spindle, to connect the pipe 70 to atmospheric openings 68. The cam 79 engages a pin 80 on the valve stem and when the pedal is in release position the cam is clear of this pin and the atmospheric openings 68 are closed, and when the pedal is moved for application of the brakes the inside of the cam engages the left-hand side of the pin 80 and merely extends the two spring telescoping sections of the valve stem. Power may be derived from the intake manifold of the vehicle engine or an air compressor.

Title: Improvements in and relating to protective systems for electric transmission lines
IPC: H02H7/26
Filed: 1955-11-21
Abstract: 794,134. Protective cut-out systems. GENERAL ELECTRIC CO. Nov. 21, 1955 [Nov. 19, 1954], No. 33283/55. Class 38 (5). At each terminal station of a transmission line 11, 12, 13 there is provided fault-detecting means, fault-locating means, signal transmitting and receiving means and a circuit breaker tripping relay TX so arranged that on the occurrence of a fault internal or external to the protected section, signals are transmitted from all the transmitting means to block the operation of the tripping relays, then if the fault is internal, each fault-locating means causes the transmission of the signals from the associated transmitting means to cease so that on the termination of the blocking signals from all the stations, the tripping relays cause the opening of the circuit-breakers 14 at all the stations. The block circuit diagram of Fig. 1 indicates the equipment at one station. In this equipment, the fault-detecting means comprise a ground fault " starting " relay Gs and a phase fault impedance " starting " relay #s, and the fault-locating means comprise a ground fault directional " tripping " relay GT and a phase fault " tripping " relay #t, of the mho distance type. When a fault occurs, relay Gs or #s immediately acts on a control relay CR which causes a transmitter T to transmit carriercurrent over the line 13. This transmission is received by the receiver R which applies a blocking signal to an oscillator OSC to make the oscillator unable to produce an output voltage for the operation of the tripping relay TX. If the fault is internal, the relay Gt or #t operates after the relay Gs or #s to render the control relay CR effective to stop the operation of the transmitter T and to apply a control voltage to the oscillator OSC. Since the other stations will also cease transmitting if the fault is internal, the oscillator no longer receives a blocking signal and applies an output voltage to the tripping relay TX which effects the energizing of a trip coil 31 to trip the circuit-breaker 14, opens the circuit between the control relay CR and the transmitter T to prevent any further transmission of the blocking signal as the relays &c. reset, and closes a circuit so that the tripping signal from relay Gt is used to cause a neon fault indicator (not shown) in that relay to strike. A relay 27 associated with the relay Gs renders the relay Gt ineffective until all the poles of the circuit-breaker have been properly closed. The relays Gs, Gt may be electronic and be arranged so that the relay Gt is inoperative until it receives a co-ordinating signal from the relay Gs, both relay circuits including time delay elements to produce correct sequential operation. The arrangement of these relays is described and illustrated in detail in the Specification. An out-of-step blocking relay OB may be provided to prevent incorrect operation of the system due to a " power swing."
