Title: Securing an Outer Cladding to a Roof or Wall Structure and Hook Bolt Therefor
IPC: F16B35/06
Filed: 1980-02-22
Abstract: In order to simplify and speed up the fixing of an outer cladding on a roof or wall, the cladding 4 is secured by inserting a hook member 7 through a hole 6 in the cladding 4 and engaging a hook 15 on the hook member 7 under a downwardly or laterally projecting roof structure element 10''.

Title: A Vital Timer
IPC: G04G99/00
Filed: 1980-11-07
Abstract: In a microprocessor timer for energizing a relay at the end of a preselected time interval plural data words corresponding to a preselected time interval are generated, loaded into a plurality of registers within a microprocessor, which are decremented by means of a program loop for the duration of the time interval determined by the magnitude of the numbers loaded therein.

Title: Television frame signal synchronizing circuits
Inventor: WILKINSON JAMES HEDLEY
IPC: H04N5/04
Filed: 1983-05-18
Abstract: A television frame signal synchronizing circuit comprises a presettable cyclic counter and a maximum count detector, a clock pulse generator for supplying clock pulses to the counter, a store for storing the count of the counter, and a source of reference frame pulses to which input frame pulses are to be synchronized, each reference frame pulse causing the count stored in the store to be loaded into the counter. A television signal processor is capable of adjusting the timing of television signals passed therethrough in dependence on a reverse frame pulse, the carry signals from the counter forming reverse frame pulses for supply to the television signal processor for adjusting the phase of the television signal passed therethrough, the television signal including the input frame pulses at least some of which are derived and supplied to the store which thereupon stores the count of the counter. The phase of the television signal is therefore adjusted until the input frame pulses are in synchronism with the reference frame pulses.

Patent GB-2154282-A (GB)
Title: Fluid pressure actuators
Inventor: HOLMES WILLIAM BRIAN
IPC: F15B15/14
Filed: 1984-02-14
Abstract: The cylinder has a piston 2 within a body 1 constrained to move along a screw by means of a pressure such as pneumatic or hydraulic pressure. The linear motion of the constrained piston imparts a rotary motion to the screw 4 which in turn operates a signal generator 5. This can give the relative position of the piston within the cylinder to a high degree of linear accuracy at any time. When stationary the piston 2 is locked in position by the brake piston 8 and cone 7. The stiffness of the locking system can give controlled operating conditions plus a fail-safe device in the event of loss of operating pressure. <IMAGE>
