Title: Closed circuit breathing/diving apparatus
Inventor: HOWIE ROBIN MIDDLEMASS
IPC: A62B7/10
Filed: 1987-03-06
Abstract: A closed circuit breathing apparatus has a breathing circuit comprising a breathing bag (4), personal gas supply means (5), a purifier (3) to remove carbon dioxide, a source of oxygen (1) and optionally a source of ballast gas (2). An oxygen sensor (7) provides an oxygen concentration signal to a control means (9), which compares the signal with desired values. If the desired value is not met, an actuation signal is generated to dose oxygen from cylinder (1) or nitrogen from cylinder (2) into the circuit. Another oxygen sensor 6 and/or control of the ballast gas may also be provided. If used for diving, a water pressure sensor (2, Fig. 2, not shown) may additionally provided for depth control of the breathing gas. Improved safety and economy are offered. <IMAGE>

Title: Light display generator for audio apparatus
Inventor: NABA SHAUL
IPC: A63J17/00
Filed: 1987-07-27
Abstract: Audio reproduction apparatus is provided with a light display generator 18 and a ground glass screen 17 onto which a changing light display 35 is projected. The light display generator comprises a laser light source 20, first and second mirrors 29, 30 and motors 23, 24 for rotating them about axes at acute angles to their reflecting surfaces. The laser beam is directed at the first mirror 29 at positions offset from its axis of rotation. A cone of light 34 is thus reflected by the first mirror to the second mirror 30. Rotation of the second mirror results in a Lissajous-like pattern of light to be reflected by the second mirror and displayed on the screen. The pattern can be varied by controlling the speed of the two motors at random. A bounce mirror 27 projects the display on to the back of the screen 17 or on to a wall of a room when the screen is hinged open. <IMAGE>

Patent GB-2319146-A (GB)
Title: Demodulation for an FSK frequency modulated and frequency hopped transmission
Inventor: LAURENT PIERRE ANDRE
IPC: H04L27/152
Filed: 1989-05-22
Abstract: The demodulation method is such that for each symbol, the most probably transmitted frequency is selected by analysis of the ratios between the power of the received signal and the square of the average jamming power stored for each of the possible frequencies, the selected frequency being that which leads to the highest ratio. The average jamming powers for each possible frequency, stored and updated throughout reception are the powers received at the frequencies that have not been selected as being the frequencies transmitted in the successive symbol intervals. The symbol corresponding to selected frequency is validated only if a decision reliability criterion is satisfied. The device implementing this method comprises as many demodulating subassemblies as there are possible frequencies, a memory for storing said jamming powers, decision means, and control and synchronization means. Application to the tranmission of weak signals in the presence of high-power jamming.

Title: Electroacoustic transducer
Inventor: LETICHE MICHEL
IPC: B06B1/06
Filed: 1989-07-05
Abstract: The structure is of the co-called "Tonpilz" general type, i.e., comprising a radiating horn (10), a rear mass (20) and a motor formed by at least one piezoelectric element (30) interposed between said horn (10) and said rear mass (20), and electrically excited so as to produce a vibration transmitted to the horn (10). Said piezoelectric element (30) is submitted to an electric field with a direction perpendicular to the main direction of polarization of said piezoelectric material so as to stress the latter in the shear mode. Said horn (10) and rear mass (20) are terminated one in the form of a foot (11) and the other in the form of a U accommodating said foot between rectilinear arms (21), the foot (11) and arms (21) extending parallel to the longitudinal direction of the transducer, and said motor being formed by substantially parallelepipedal piezo-electric elements (30) disposed between the facing sides of said foot (11) and of each arm (21), these elements (30) being fitted with electrodes (36, 36') creating an electric field parallel to said longitudinal direction, and the shape of said piezoelectric elements (30) being chosen so as to promote the strain of the piezoelectric material substantially in this longitudinal direction. This configuration allows to considerably lower the resonant frequency of the assembly with moderate overall size and weight and with a small volume of piezoelectric material. <IMAGE>

Title: Electrically driven power hand tool
Inventor: FRAUHAMMER KARL
IPC: F16N11/00
Filed: 1990-10-10
Abstract: Until now, the axial mounting of the crank gear on electrically driven power hand tools with crank gears, in particular percussion hammers, has not been satisfactorily solved. This may result in premature wear in the crank gear. A simple, inexpensive measure is proposed which ensures both the axial mounting of crank disc (12) and connecting rod (9) and also the lubrication of the crank boil (11). This is achieved by a cover (25), which is fitted into an opening (23) of the gear housing (16). On the cover (25) there is formed a flat annular surface (26) covering the path of bolt (11), which surface only leaves a narrow gap (27) free with respect to rod (9) to prevent offsetting or dropping-out of rod 9 from bolt 11. In the cover (25) there is formed a hollow space (28) filled with lubricant, from which space a high viscosity grease gradually passes into the sliding bearing between bolt (11) and rod (9). The invention can be applied to all power hand tools with crank gears. The cover may have two adjoining metal parts 32, 33 with an opening 36 in one part to allow egress of lubricant. <IMAGE>
