Title: Strapping tools
IPC: B65B13/32
Filed: 1971-01-16
Abstract: 1346067 Seaming SIGNODE CORP 16 Jan 1971 [1 April 1970] 584/71 Heading B5K [Also in Division F2] In a tool having an air motor M, for tightening a thermoplastic strap loop around an article A and friction welding the strap ends, the welding step is initiated by the operation of a plunger valve PV, responsive to air pressure at the motor supply port, so that, as the tension developed in the strap S reaches the required value, a sudden rise in air pressure, due to the torque in the drive to motor-driven strap-tightening wheel 42 almost stalling the motor, actuates the valve PV. The rise in air pressure moves the spool 274 against the action of spring 277, so that air is supplied to port 306 of ram 162, 164. Ram 162, 164 is operative to de-clutch (clutch C) the drive to wheel 42 and the speed of the motor M is increased by cutting out the throttling effect of the speed valve. Ram 162, 164 also lowers welding jaw 120, which is continuously vibrated by an uninterruptible drive from motor M. The strap is cut just before jaw 120 reaches the welding position. An adjustable timing valve is connected through an accumulation chamber 322 to a stop piston 247, to control the time taken for welding. When piston 247 is actuated, plunger 212 is relased from catch 240 and is returned into its initial pre-start position, by spring 228, to cut off the air supply to the motor M and switch it from port 306 to port 301, thus reversing the direction of ram 162, 164. Welding jaw 122 is accordingly retracted upwardly and clamp foot 52, released by latch 70, lowered downwardly, so that the welded strap can be removed from the tool.

Title: Mining apparatus
Inventor: LAMPL FREIDRICH
IPC: E21F13/08
Filed: 1965-01-06
Abstract: 1,065,101. Mineface conveyers. DOWTY MINING EQUIPMENT Ltd. Dec. 20, 1965 [Jan. 6, 1965], No. 601/65. Heading B8A. [Also in Division E1] If a conveyer 1 " creeps " along a working face 2 and displaces advancing jacks 6 relative to roof supports 3, the jacks are brought back to their correct attitude relative to the conveyer 1 by means of jacks 14, 16 and chains 12. Each advancing jack 6 is connected to a bracket 9 which is slidably mounted on a rail 11 secured to the conveyer 1. Assuming that the mine floor is sloping downwardly left to right in the drawing, the jack 16 is first contracted by an amount equal to that by which the conveyer has crept and the first group of three brackets 9 is slid along the rail 11. The first jack 14, which at this stage is unpressurized, is thus extended. After locking the jack 16 the first jack 14 is contracted by the creep amount to slide the brackets 9 of the next group along the conveyer. The other jacks 14 are similarly operated one after the other. The roof supports can then be advanced in the usual way. The relatively long stroke of the jack 16 enables several adjusting operations to be carried out before the jack 16 becomes fully contracted. In an alternative, the cylinder of each adjusting jack is secured, for example, to a rope or chain which extends along the rail 11 and which is anchored to a device which does not creep with the conveyer.

Title: Improvements in and relating to the synchronisation of cine-film projectors with sounrecordings on tape
IPC: G03B31/04
Filed: 1964-01-08
Abstract: 1,107,503. Automatic speed control. C.N. STUART. April 8, 1965 [Jan.8, 1964; March 10, 1964], Nos.831/64 and 10112/64. Heading G3R. In a system for automatically synchronizing a cine film projector with sound recordings on tape, a synchronizing signal recorded on the tape is compared with a signal dependent on movement of the shutter of the projector. As described, a photo-transistor responsive to light influenced by a projector or camera shutter, or a commutator on a camera drive shaft, produces a pulse output which is amplified, squared, differentiated, and divided to modulate a transistor oscillator energizing a separate head of a multi-track recorder on which the sound recordings are made. Then, during reproduction, switches are operated manually so that the oscillator becomes an amplifier of the synchronizing signals from the tape which repeatedly set a flip-flop circuit to one state after the pulses derived from projector flicker set it to the other state. The relative times for which the flip-flop is in one state or the other control through a blocking oscillator the average conductivity of a silicon-controlled rectifier regulating the speed of the projector motor to maintain synchronism. Operation of a push-button controlled transistor-operated relay ensures that the supply to the projector motor is switched off until the first pulse arrives from the tape so that the apparatus starts correctly in synchronism. A rectifier and meter associated with the flicker-produced pulses indicates pulses per second and hence projector speed. A transistor circuit is provided to ensure that the projector motor is not stalled if the synchronizing pulses fail.

Title: Satellite communications system and apparatus
Inventor: BARAN PAUL
IPC: H04B1/66
Filed: 1986-07-31
Abstract: A satellite communications system, which is inherently power limited, employing spread spectrum techniques in order to trade-off bandwidth for small ground station antennas. In a one-way system embodiment a central station (14) transmits data to a satellite (3) for relay to a large number of small antenna receiving stations (4), the transmissions being spread spectrum encoded with spreading code lengths selected to provide adequate data recovery at the least sensitive station to which the transmissions are directed. Spreading codes may also function to address particular stations. In a two-way system embodiment, the central station (14) additionally functions as a terrestrial relay station. A plurality of small antenna transmitting stations, at least one of which may be at the same site as a receiving station, transmit code division multiplexed data via the satellite to the central relay station using sufficiently long and distinct spreading codes as to permit adequate data error rates and to distinguish the transmissions of the various stations. The central relay station reformats the received data for retransmission to the satellite for relay to the receiving stations.
