Title: Cassette hold and ejection mechanism - has double spring loading, giving two equilibrium positions
Inventor: RUBI HORST
IPC: G11B15/675
Filed: 1975-07-05
Abstract: A cassette tape player has a spring loaded arrangement of levers and a ratchet for holding the cassette in position and ejecting it when suitably actuated. The mechanism is an improvement on the cassette player mechanism described in P 2454698.5. It consists basically of a lever arm (2) which can be rotated about a pivot to insert and reject the cassette depending on the direction of movement. This movement takes place under the influence of two opposed springs (33, 36) one on each side effectively of the pivot, so that two distinct equilibrium positions are possible. The details of the action and the required geometry are described at some length.

Title: Steam iron with water supply control valve - with no drop in steam output and with uniform exit of steam at sole plate
Inventor: REUSSWIG ERNST
IPC: D06F75/18
Filed: 1975-07-21
Abstract: Steam iron comprises a water tank and an aveporator chamber, and a valve for controlling supply of water to the evaporator chamber. Between the valve outlet and the evaporator chamber is a tubular connector. This is in contact with the heating element or the heated sole plate. Pref. the connector is curved, and its outlet end is bevelled. Water can pass from the valve to the evaporator chamber without obstruction by steam bubbles, and steam comes out of the sole plate uniformly. The amount of steam produces is independent of the degree of filling of the water tank. Even when the tank is almost empty, the amount of water required for steam production is drawn in via the drip valve and tubular connector and uniformly conveyed into the evaporator chamber without obstruction.

Title: Emergency tread for lorry wheel - with plastic segments threaded on tensioning wire passed around central slot
Inventor: EYERLE ANTON
IPC: B60C7/08
Filed: 1975-07-23
Abstract: The emergency running tread for the lorry wheel has a number of moulded plastic segments (1) provided with a central slot through which a tensioning cable (2) is stretched.

Title: Maximum energy supplied monitor and switch - uses digital electronic techniques to control electric energy supplied to installation
Inventor: SEIBT ARTUR DR ING
IPC: H02J3/14
Filed: 1976-02-12
Abstract: A monitor network uses electronic digital techniques, by means of which the energy supplied to an installation once a particular period may be compared with a set point value and the supply interrupted when that value has been exceeded. The equipment consists of an energy switching network (N) containing suitable power switching relays, connected to a mains supply (10). Two connecting networks produce counts dependent on the set point (ZS) and used energy (ZI) and a comparison network (V) drives an energy switching circuit (AE) and a time control (SE), which determines the time before the next energy supply cycle. This timing network consists of a counter (SZ) driven synchronously with the set point counter, which affects the state of three control flip flops (FF1 FF2 FF3) via decoders (KS1, KS2, KS3). These are reset at the start of a supply cycle (R) and produce a signal (E) when the energy supplied has exceeded the set point value.
