Title: Door support mechanisms for a container
Inventor: HARDING ALAN BLAIR
IPC: B61D39/00
Filed: 1983-01-29
Abstract: A door support mechanism for a top-loading railway wagon comprises two pairs of swinging arms 15 and 16, 20 and 21, connectors 13, 14 being attached to the door 12 of the container, and releasable detents securing a part of each arm of a pair to the associated connector. The detents automatically operate in such manner that disengagement of either one of the arms from the associated connector causes the detent associated with the other arm to operate to prevent disengagement of said other arm from the connector, so that one of said arms remains at all times in engagement with the connector. This permits the door to be displaced to either side, as required, of the opening in the upper part of the wagon, depending on which arms are engaged with the connectors. <IMAGE>

Title: Circuit for sensing the status of a voltage input over a wide range of voltage levels and waveforms
Inventor: PELOWSKI KENNETH ROBERT
IPC: G01R19/165
Filed: 1984-02-16
Abstract: The circuit senses the status of a voltage input over a wide range of voltage levels and waveforms over a first predetermined range by using a voltage conditioning circuit BR1, 26, OPI 30 to generate an output signal having a voltage within a second predetermined range. Bridge rectifier BR1 rectifies any AC waveform from sensing means 12 and a limiter D1 which may be a zener diode or a varistor changes the signal waveform to the first predetermined range as shown by waveform C. A zener diode D2 ensures that a minimum voltage level is present before activating an opto isolating circuit OPI. The opto isolation circuit OPI generates an output signal having a voltage within the second range, denoted by waveform D in response to an input signal having a voltage over a first predetermined range C. When photo transistor 76 conducts a capacitor C3 discharges via R6 and 76 and when the capacitor C3 voltage becomes lower than the reference voltage at the noninverting input 102 of a comparator 41, the comparator 41 will produce an output to a central processing unit 16.   <IMAGE>

Title: Display installation
Inventor: BASHIR MOHAMMED
IPC: B67D1/12
Filed: 1984-04-10
Abstract: Each time a glass of beer is drawn via beer tap 1, a signal is passed to a master control unit 2 which generates randomly a number in the group of integers between (and including) 1 and 10; the unit then compares the generated number with three predetermined numbers (e.g. 2, 7 and 9) within that group which are held in a memory store of unit 2. If the generated number is one of these three predetermined numbers, then the unit 2 switches on a videotape recorder 3 containing a tape so as to play the recording on a separate television receiver 4; after one minute, the unit 2 stops the video recorder 3 to terminate the display. If the generated number is not one of the predetermined numbers in the group, then the unit does not switch on the videotape recorder 3. <IMAGE>

Title: Push-button combination lock
Inventor: YUNG-SHENG LIN
IPC: E05B37/18
Filed: 1985-09-19
Abstract: The sliding member 4 which is released on depression of the correct combination of buttons is not in direct contact with the latch 1 which engages the hook 2 of a padlock so that stress on the hook is not transmitted to the sliding member thereby making it difficult to find the correct combination. On release of the sliding member 4, a second sliding member 5 which engages the latch can be released from engagement with the latch. 0n release of the second sliding member a spring-loaded intermediate element 3 which has a shaped end in engagement with the latch can be depressed to cause disengagement of the latch from the hook. The push buttons are held in the depressed position by spring-loaded checks 94 mounted on a sliding plate 95 which can be moved on depression of a return button 8 to cause simultaneous release of all the push buttons. The characters corresponding to the combination buttons are coated with phosphorescent material so as to enable one to discriminate between the characters in the dark. <IMAGE>

Title: Optical displacement sensor for timing geophones in seismic survey equipment
Inventor: BOYLES RICHARD
IPC: G01V1/26
Filed: 1985-09-28
Abstract: An optical pattern 3 is interposed in a light path between a transmitter and a detector 9, movement of the optical pattern 3 causing a frequency to be generated by the detector, and this is amplified and converted to a voltage. When the optical pattern is fixed to the hydraulic ram 4, 5 of a seismic survey equipment, when the ram hits the ground the pattern stops and therefore so does the output. This event causes a monostable circuit to provide an output pulse indicative of the event, and this is used to synchronise the seismic geophones. <IMAGE>
