Patent GB-2108328-A (GB)
Title: Electrical energy source
Inventor: SPENCER JOSEPH
IPC: H02K35/02
Filed: 1982-10-08
Abstract: An electrical energy source, particularly suitable for portable emergency equipment such as cardiac defibrillators, uses a small explosive charge (10) of which the energy is converted into a short intense electrical pulse by an electromechanical convertor for example a piezoelectric transducer. The explosive charge gases cause rotation of a freely rotatable turbine rotor (11) whose rim (12) is corrugated to cause axial percussion on an end piece (13) of a piezo-electric crystal pack (14). The electrical pulse train produced by the crystal pack is rectified for charging the defibrillator circuit. <IMAGE>

Title: Current duration discriminator
Inventor: MORRIS RAYMOND THOMAS
IPC: G08B5/30
Filed: 1983-01-14
Abstract: To discriminate between relatively shorter and relatively longer currents, a member 76 is moved by passing the current through an electromagnetic mechanism, e.g. a coil (32) and armature 36 arrangement, thereby to propel a rotor 60 towards a stop 78. After striking the stop, the rotor returns towards the first position and, if not intercepted by member 76 thereat, moves on to said second position 80, thus indicating that current in the coil lasted for longer than a predetermined time. The device shown has a flag on the rotor for providing an indication or the rotor could carry contacts to constitute or the device could be a relay. <IMAGE>

Title: Applying biscuits to confectionery material
Inventor: IMHAUSER GERD
IPC: A21C15/00
Filed: 1983-08-10
Abstract: When applying biscuits to confectionery material particularly to chocolate contained in mould cavities it is desirable for the biscuit to assume a position in which its edges are parallel and equidistant to the wall of the mould cavity. To this end, after the biscuit has been dispensed onto the viscous confectionery, the mould cavity is vibrated for a short time by means of a vibrator. The high- consistency confectionery material contained in the mould cavity tends to rise up the wall of the mould cavity and thus form a sort of liquid wedge which propels the biscuit into the required central or equilibrium position. <IMAGE>

Title: Machine for washing and drying domestic laundry
Inventor: CASH PETER
IPC: D06F58/18
Filed: 1985-10-02
Abstract: In a machine for washing and drying domestic laundry a condenser (26) for removing moisture from the air used in the drying operation consists of a vessel (27) which has the form of a U lying on its side and which comprises upper and lower elongate chambers (28 and 29) communicating with one another at one end. Adjacent its other end the lower chamber has an inlet (31) for the moist air. During the drying operation, cold water is fed continuously into the lower chamber (29) though a valve-controlled feed pipe (35). Water leaves the lower chamber through an outlet (36) in the bottom of the chamber and a pipe (37) which projects upwardly into the chamber for a short distance to form a wall (38) around the outlet, which wall acts as a weir to determine a constant level of cooling water (39) in the lower chamber. The moist air flows over this water so that the water vapour in the air is condensed and precipitated from the air stream. The air then flows into the upper chamber (28), where drops of water picked by the air flow over the cooling water are deposited on the walls of this chamber to run back into the lower chamber. The air finally leaves the condenser through an outlet (32) in the top of the upper chamber for recirculation in the machine. <IMAGE>
