Patent GB-612812-A (GB)
Abstract: 612,812. Fluid-pressure servomotor-control systems. SPERRY GYROSCOPE CO., Inc. Nov. 30, 1944, No. 23975. Convention dute. May 15, 1942. [Class 135] [Also in Groups XXIV and XXXV] In a control system for an automatic pilot for aircraft, the pressure fluid is applied continuously to both ends of the servomotor, the pressures in the two ends being variable under the control of differentially-operating valves, and on failure of power in the system, the valves are centralised by means which is normally ineffective. As applied to the operation of an elevator 10, Fig. 2, with trim tab 12, electrical signals are applied to the stator of a torque motor 21, Fig. 1, and the resultant movement of the armature rocks a lever 24 carrying valves 25, 26. The latter constitute byepass valves connected between the outlets of gear pumps 29 and a sump 35, and serving to vary the pressures applied by the pumps to the ends of servo-pistons 42, 43. Servo-pistons 43 are connected by a rack 44, and the movement of the pistons rotates a pinion 45 con- , nected to a cable drum 15 which, through cables 14 and see-saw lever 11, actuates the elevator. Servo-pistons 42 carry an arm 51 which can make contact at 52 or 53 to close the circuit of a soleniod 61 or 64 to actuate a reversing switch 63 controlling the operation of a reversing motor 16. The latter actuates the trim tab through a slip clutch 67, a pulley 17, and cables 18, 20. Rotation of pulley 17 rotates a pinion 60 and worm 56, the latter controlling limit switches 54, 55 which, when operated, open the solenoid circuits 64, 61, respectively, and so stop the motor 16. Sequential movements of the trim tab in the one direction are integrated. Included in the circuit of the electric motor 30 driving the pump 29 is a solenoid 50 with an armature carrying V-arms 47, and when the power is cut off, a spring 49 forces up the arms 47 into contact with lever 24 to centralise the valves 25, 26. Servo-pistons 43, Fig. 5, are of metal with cup-shaped leathers, and the rack 44 connecting them bears on a roller 92 housing a rotatable adjusting eccentric 94. When it is desired to operate the control surfaces manually, clutch 67 is actuated through solenoid toggle mechanism 70 and cable drum 15, Fig. 3, is disconnected from the servo-driving pinion 45 by pulling on cable 85, this latter drawing a block 82 of a toggle mechanism past the dead-centre position to withdraw dogs 76 from grooves 78 in the drum 15. The toggle mechanism comprises pairs of bow spring links 80, 81, each pair having a pin-and-slot connection at one end with a central solid link and being pivoted at the ends to the dogs 76 and the block 82. The end of cable 85 is connected to a plunger 83 housed in the hollow driving shaft which carries pinion 45, and the cable runs through a bell 87 carried by the shaft. Specification 612,804 is referred to.

Title: Simulcast transmission system
IPC: H04H20/67
Filed: 1978-06-30
Abstract: A system of the type wherein transmissions of the same information are simultaneously broadcast by spatially removed transmitter sites. A control centre (20) establishes transmission links to the transmitter sites (1,2,3,4). The centre (20) includes electronic storage (26) for determining the required time delay for each signal applied over a predetermined line (e.g. paths 1,2,3) to assure information phase coherency of overlapping transmissions. Upon the establishment of a new link the appropriate time delay is recalled from memory and used to program a bucket brigade (28) to thereby provide the required delay to signals carried over the link. <IMAGE>

Title: Knitwork drawing device in a double cylinder circular knitting machine
IPC: D04B15/92
Filed: 1978-07-13
Abstract: A knitwork drawing device which has a hollow piston rod movable axially through one of the needle cylinders in a double cylinder circular knitting machine, and a knitwork retaining member arranged at the height of the stitch-formation area and rotatable with the needle cylinders. The hollow piston rod is secured to a fluid-operated piston slidable in a cylindrical chamber coaxial with the needle cylinders. Tensioning of the knitwork is effected by leaving the hollow piston rod to rest on the knitwork being knitted, which is held at its initial portion by the retaining member internally of the hollow piston rod and by the needles which continue to knit externally of the hollow piston rod. The whole stroke of the piston and hollow piston rod is thus the half of the whole length of the knitwork and the axial dimension of the knitting machine is considerably reduced.

Patent GB-2019072-A (GB)
Title: Alarm Systems
IPC: G08B13/16
Filed: 1979-04-12
Abstract: An intrusion alarm system has a number of satellites each connected to a master by an unshielded cable having only four conductors, namely two power conductors, a drive signal conductor which supplies drive to the satellite, and an alarm conductor. When an intrusion is detected by a satellite, it transmits an alarm signal on the alarm conductor to the master and also sets a latch in the satellite. The master has a rocker switch which an investigator turns off when he arrives at the supervised premises. This turns off the drive signal and causes a counter in the master to send a set of pulses to the satellites on the drive conductor. Each satellite counts the pulses if that satellite's latch has been set and sends a pulse back to the master on the alarm conductor immediately after a count respective to the satellite. The master stores and displays the pulses. A tamper switch in each satellite also operates to set the latch. A test transceiver is provided to test each satellite. <IMAGE>

Filed: 1979-09-04
Abstract: A method of remelt surface hardening of a cast-iron workpiece, preferably an unalloyed cast-iron camshaft, by fusion of the workpiece surface along fusion tracks using an energy beam directed onto the surface followed by cooling of the fused tracks by heat dissipation into lower-lying layers of the material of the workpiece at such a rate that in the resolidified metal of the fused tracks, a ledeburitic structure is formed, characterized in that the said cooling is delayed by supplying heat to the workpiece so that a wholly or partially austenitic layer underneath the solidified ledeburite layer cools at a sufficiently slow rate so that no structural transformation into martensite occurs. After the fusion has been effected, the said cooling is preferably effected by placing the workpiece in a heated furnace. The energy beam is preferably an arc beam. <IMAGE>
