Title: Packaging device for dried figs - in which agglomerated mass is sepd. by transparent film into convenient portions
IPC: B65B25/08
Filed: 1973-04-18
Abstract: Packing device is intended for dried fruits, such as figs, which have an adhesive pulp. Normally the figs are cut open and agglomerated into parallelepipedal packages; these are covered with a cellulosic or synthetic film. For use, the consumer slices the package into portions; even if there is no loss there is difficulty in getting the portions equal and presentable. In the new pack, the agglomerate is cut into a number of slices by a series of parallel knives mounted in a moving frame. A transparent film is arranged to coat the adjacent vertical surfaces of each unit and cover the tops of alternate slices and also the lower ends. The reconstituted agglomerate is then wrapped in a sheet of the same film. The consumer has only to remove the outer wrapper in order to separate the individual and equal slices which no longer stick together.

Title: Gas spring with inbuilt damper - has cross-sectional area of damping orifice changed with direction of piston motion
IPC: F16F9/02
Filed: 1975-12-15
Abstract: The gas spring consists of a cylinder (1) and piston (7). The piston has a limited degree of axial travel between the fixed sleeve (61) and the retaining washer (62). An orifice (74) connects the radial grooves (710, 720) on opposite sides of the piston (7). When the piston moves towards the closed end of the cylinder (1), the gas pressure forces it against the sleeve (61) so that there is a gap between the piston (7) and the washer (62) giving the maximum opening of the orifice (710) and so providing only minimum damping. Movement in the opposite direction closes the gap so that the orifice (710) is partly obstructed by the washer (6), providing maximum damping.

Title: Automatic switching for release of targets for competitive shooting - has launch signal controlled from programmed memory unit in response to microphone voice input
IPC: G05B19/07
Filed: 1976-03-31
Abstract: Automatic switching from vocal command is used to release targets for sporting or competitive shooting. Adjustment is available to ensure equitable distribution automatically for a number of shooters. At each shooting base is located a microphone connected to a switching unit. Signals are calibrated to provide uniform duration for application to conditioning and validation circuits and to memory circuits. A pulse generator issues programme advance pulses when the final memory reaches a stable state. This pulse increments an address counter for a programmed memory whose output is decoded to select shooting station and microphone. It also causes a launch switch unit to issue firing signals.
