Title: Door lock controlled by handle or key - has retractable bolts for operation by handle or key
IPC: E05B55/00
Filed: 1974-03-22
Abstract: The lock is for insertion within the thickness of door panels during factory prodn. and is designed to obviate lock refitment due to change of function of the door unit, and accomplishes this by providing a mechanism that simply adapts to form a basic security lock or a lever handle lock with or without dead locking. The mechanism embodies a sliding bolt (6) capable of being withdrawn against spring pressure. A dormant locking bolt (26) is controlled by a cylinder lock (36), and components allow the withdrawal of the sliding bolt after unlocking of the dormant bolt which is truncated so as to remain within the housing.

Title: Magnetic catch and buffer for maintaining door open - has telescopic magnetic rod and tube with different strength springs
IPC: E05F5/08
Filed: 1974-04-11
Abstract: The device has a co-axial intersliding arrangement of an inner magnetic rod (8), an intermediate tube (4), and an outer tube (3). The rod and intermediate tube project from the outer tube and retract under door pressure against contained coil springs (5, 10) to effect retraction of the rod (8) and magnetic engagement of a door mounted disc (11), and continued retraction with absorption of door impact. The stepped diameter rod and intermediate tube engage inner returns on the intermediate and outer tubes to prevent escape of the rod and intermediate tube. An end stop (6) is locked in the end of the outer tube by a small pin.

Title: Ic engine using oxygen as fuel - uses oil to initiate ignition of the fuel
IPC: F02B43/10
Filed: 1974-05-15
Abstract: The engine is fitted with an injector which meters the oxygen in exact quantities to the combustion chamber. Combustion is caused by the presence of grease which are introduced by the rotation of the engine. A flywheel enables the repetition of the combustion cycle. The use of oxygen as a fuel enables a greater natural source of supply to be used. The fuel is cheaper than the fuels currently used and is not polluting.

Title: Microwave source location appts. using antenna system pair - switches comparator inputs from receiver with switched input from antennae
Inventor: JANEX ALBERT
IPC: G01S3/32
Filed: 1974-08-06
Abstract: Comparison of amplitudes or phases of signals received by two directional antenna systems is effected. An antenna system may comprise two quarter wave dipoles normal to a ground plane each with reflectors. A third antenna comprises a quarter wave dipole located in the centre of the line between the first two antennas. A hybrid ring is placed under the antennas and has one output connected to an adjustable attenuator and a second output connected to a directional coupled to which the single dipole is also connected via a phase shift circuit. These microwave signals are converted to a lower frequency for detection and comparison and a multivibrator ensures switching of the microwave channels to the detector circuits. The comparator provides a signal when the amplitude difference is greater than a given value.

Title: Connection of prefabricated building elements - using bevelled pins to prestress connecting rods giving rigid joints
IPC: E04B1/61
Filed: 1975-08-11
Abstract: Each of the panels has a frame comprising two uprights (3A, 3B) and two cross-pieces and the panels are placed vertically side by side on a concrete base. Prior to being bracketed together, the rods (9) are put in place, straddling the joint (8) between two adjacent panels. At the end of each rod is an eye into which is forced a bevelled pin. This pushes the edges of the panels one against the other towards the joint, bringing about the prestressing of individual elements. The same rods used longitudinally, but they are welded to a metal strip which straddles the joint (8), being housed on either side in a longitudinal groove.

Title: Mechanical torque limiting system - uses locked separation of two annuli to disconnect driving mechanism of tapping machine
IPC: F16D43/202
Filed: 1977-01-10
Abstract: The torque limiter is easily fitted to the chuck or spindle of a tapping machine. The rotating mechanism of the machine is attached to the tap holder (12) and the driving collar (19). The base of the collar has equally spaced tenons which fit into corresponding slots on top of the annulus (17). The corresponding end-faces of the tenons and slots are inclined so that a certain resistance to rotation of the tap (R) causes the faces to slide away from each other until the driving collar and annulus are disconnected. The annulus is connected to the tap holder by means of equally spaced ball bearings (16) in cavities in them both. A ramp gradually ascends the inner surface of the annulus, starting about halfway up a cavity. Thus, when the driving collar and the annulus are disconnected, the balls (16) rise up the ramps and maintain the disconnection, against the pressure of the spiral spring (20). The balls are returned to their cavities by reversing the rotation of the limiter.
