Title: Self-commutating converter with single current-limiting inductor - is between one DC input and three commutating thyristors
IPC: H02M7/515
Filed: 1974-09-23
Abstract: The self-commutating DC/AC converter has each of the three output phase-lines coupled over anti-parallel thyristors, a commutating capacitor and an inductor to a common phase-point. The first phase line is connected one way over a thyristor bridged by an oppositely-poled diode to a single inductor connected to the negative d.c. input terminal, and the other way over a thyristor bridged by an oppositely-poled diode to a single inductor connected to the positive d.c. input terminal. The second and third phase lines are connected in an identical manner to the same two inductors. The configuration reduces the number of current-limiting inductors, as there are usually three for each d.c. input.

Title: Packing process for fragile soil prods. such as mushrooms - on spikes in bed of foam
IPC: A23L1/28
Filed: 1975-06-04
Abstract: Preserving and packing process is intended for fragile growth prods. such as mushrooms. The packing consists of a base with raised sides. Spikes are suitably distributed over the surface to receive the stalks of the individual mushrooms which are impaled on these spikes.

The base is itself associated with a box made from wood panels with a peripheral reinforcement. The packed assembly is finally covered with a sealed sheet of a transparent vegetable nature. The process allows mushrooms to be kept in the fresh state for a limited time by the partic. reliable packing method. They may also be preserved in the frozen state for several months in the same packing.

Title: Shock absorber bushing on motor vehicle - is prestressed by expanding inner bush and reducing face angles to eliminate static moulding stess
IPC: B60G13/00
Filed: 1975-08-01
Abstract: The shock absorber bushing has an inner ring (5) in the form of diverging coned surface (9, 10) each side of a central bush. This holds the shock absorber shaft. A 'J' section ring (6) is welded to the vehicle body (2), the curved portion facing the inner ring. Rubber (4) is moulded into the annular space between the rings. On curing, stresses are set up, weakening the bond between the rings. The bushing is deformed to induce prestressing and cancel out the stresses. This is done by expanding the inner bush diameter reducin the angle of each coned surface, pressing these mutually inwards.

Title: Measuring system for oscillation amplitude of timepiece balance - ticking sound is converted into electrical signal
IPC: G04D7/00
Filed: 1975-12-19
Abstract: The measuring system for the oscillation amplitude of the timepiece balance, detects the ticking sound provided by the action of the balance mechanism to provide an electrical signal. This is used to provide a first signal providing the time interval between the release of the balance and the following impact against the hammer of the escapement mechanism and a second signal denoting the duration of the half period between the two end points of the balance movement. Reference pulses with a constant repetition frequency are used to obtain two count pulse series, one having a fixed repetition frequency and the other having a repetition frequency proportional to the angular sweep of the balance. The two pulse series are counted for progressive periods and the count values summated with the summations for the two series divided by one another.
