Patent GB-2104810-A (GB)
Title: Squeeze casting apparatus
Inventor: JONES MELVYN CHARLES
IPC: B22D18/02
Filed: 1981-08-27
Abstract: The apparatus comprises a die formed by male (10) and female (11) die parts. In a disengaged position the female die part is charged with molten metal and the die parts are then moved to an engaged position in which a casting cavity is formed. As the metal solidifies in the cavity, the die parts are then moved to an advanced position to apply pressure to the metal in the cavity. One die part (the female die part) is provided with an overflow passage from the die cavity for molten metal displaced as the die parts move to the engaged position. An overflow closure (28) is provided for closing the die cavity when the volume of the die cavity reaches a predetermined value. Thus a precise predetermined amount of molten metal is present in the cavity at each casting operation. <IMAGE>

Title: An EDM method and apparatus
Inventor: INOUE KIYOSHI
IPC: B23H7/38
Filed: 1982-04-15
Abstract: To increase machining efficiency a plurality of vibration horn assemblies (8) engage a tool assembly (4a, 5, E1, E2), at preselected different positions on the surface thereof. The electromechanical transducers (81) in the horn assemblies are individually energized to provide a burst of mechanical vibrations from the vibration output face (8a) of the horn member (82) in each vibrator assembly in contact with the tool assembly and to allow the burst to be transmitted to the machining surface of the machining electrode (E1, E2) to vibrationally activate a selected area thereof. The plurality of the vibrational bursts produced at the different locations on the tool assembly are combined, by being applied sequentially or simultaneously, to allow the machining surface of the electrode to be vibrationally activated uniformly over the entire area thereof. The arrangement is advantageously applicable to a variety of electrodes which may be large and to machining a deep and narrow, and/or intricate cavity in the workpiece. <IMAGE>

Title: Improvements in or relating to hearing aids
Inventor: LAURENCE ROGER FREDERICK
IPC: H04R25/00
Filed: 1982-10-20
Abstract: A hearing aid comprising a microphone whose output signal is split by high and low pass filters and supplied to two channels. Each channel includes a variable gain circuit the outputs of which are mixed and supplied to an earphone. The turnover frequencies of the filters are such that one channel limits the dynamic range of vowels whereas the other channel limits the dynamic range of consonents, thus preventing interaction and masking of consonants by preceding vowels. The intelligibility of speech is thus improved.
Patent GB-2133552-A (GB)
Title: Finding gas leaks in walls
Inventor: MENNENGA HERMAN
IPC: G01M3/22
Filed: 1983-01-08
Abstract: Search gas from gun (15) penetrating through leaks into a vessel (12) is fed to the outlet of a turbine vacuum pump (1) from where it travels against the direction of pumping to the inlet where it is detected by a detector (2). Heavy gases (air), which would disturb detection, for which the pump has a much higher compressibility than helium used as the search gas, are on the other hand largely kept back from the detector. The rotational frequency of the counter-flow pump (1) is varied until the detector signal acquires a predetermined magnitude. The apparatus has therefore a device (14), which can be automatic, for the adjustment of the rotational frequency. <IMAGE>
