Patent FI-963173-A (FI)
Inventor: HIETANEN JARMO
IPC: H04R1/10
Filed: 1996-08-13
Abstract: The present invention concerns a hearing element 11 for placement either on the earlobe 18 or in the auditory canal, in which element both a microphone 13 which registers speech and an earphone capsule 12 for reproduction of sound have been placed. The hearing element 11 is adaptable for use in conjunction with various terminal arrangements, especially mobile stations. When registering the user's speech, the perturbing signal 12' from the earphone capsule is eliminated by use of methods based on determination of the transfer function between the earphone capsule 12 and the microphone 13. For elimination of external interference sources 17, such as noise, a separate defect microphone 14 is used. To improve the speech quality and to eliminate problems arising from doubletalk, the signals 15', 12', 17' are digitally processed by use of band limitation and prediction of the capture band, among other things. <IMAGE>

Title: Control valves for spray guns
Inventor: WRIGHT JAMES ERNEST
IPC: G05D11/13
Filed: 1954-01-14
Abstract: 759,637. Mixing fluids in flow. AEROGRAPH CO., Ltd. Jan. 14, 1955 [Jan. 14, 1954], No. 1136/54. Class 86. [Also in Group XXIX] A control valve assembly for the supply of two distinct fluids to a spray gun from two pumps driven in predetermined ratio by an air motor, comprises a speed control valve for the motor actuated in accordance with the output pressure of one pump, a piston-operated shut-off valve in the air supply to the motor and a valve actuated in accordance with the output pressure of the other pump whereby air pressure is applied to the piston of the shut-off valve when that output pressure diverges from a predetermined range. As shown, an air motor 7, Fig. 1, drives through a coupling 6, a pump 1 connected by chain and sprocket gearing to drive a pump 2. The pumps 1, 2 pump paint and a catalyst liquid respectively through outlets 10, 11, from which branches 12, 13, lead to a control valve assembly, Fig. 2. Paint pressure from the branch 12 is led into a chamber 14 above a diaphragm 15 to which is attached a spool valve 16 working in a bush 17 provided with an inlet port 18 and an outlet port 19. The paint pressure is opposed by a spring 20 with screw adjustment for tension. Under normal conditions air under pressure through the inlet 18 passes the outlet 19 to the motor air inlet 7a, Fig. 1. If there is a drop in paint pressure the valve 16 moves upwards to increase the amount of air passing to the motor. Catalyst pressure from branch 13 is led to a chamber 22, Fig. 2, above diaphragm 23 attached to a spool valve 24 in a bush provided with an inlet port 25 connected to the main air supply pipe 26 and with two outlet ports 27, 28. Normally air supplied through the inlet 25 leaks through bleed-off holes 30, 31, but outside a range of catalyst pressure air is passed through one or other of ports 27, 28. When air passes through either of the ports it enters a stopping device provided with a piston 33 pressed downwardly by a spring 34 against the action of air entering below the piston and raising a valve 32. The air at the top acts to close the valve and prevent air from passing through the port 18 of the paint-pressure-sensitive valve to the air motor inlet 7a whereby the motor stops. The motor may be re-started by pressing inwardly a bleeder valve 35 enabling the valve 32 to be opened for admission of air to the motor. Specification 759,602 is referred to.

Title: Repeater and remote control systems
IPC: G05D3/16

Abstract: 550,310. Repeater compass systems. STANDARD TELEPHONES & CABLES Ltd. (International Standard Electric Corporation). Feb. 6, 1942, No. 1578. [Class 40 (i)] [Also in Group XL] In order to transmit the movements of a control member to another member without applying a load to the first member, means are provided whereby a periodically operating obscuring device produces periodic variations in photo-electric currents, these in turn produce a rotating magnetic field in a rotor, the rotor is mechanically driven in the opposite direction in synchronism with the obscuring device whereby the magnetic field is made stationary in space and holds a magnetic compass member in this stationary position, and the phase of the obscuration is made to vary in accordance with the position of the control member in order to vary the stationary position of the magnetic field so that the magnetic compass member is caused to move in correspondence with the movement of the control member. In the form shown in Figs. 1 and 8, a light beam is directed from above on discs 11, 12, the disc 12 carries three photo-electric cells 13, 14, 15 the illumination of which is periodically obscured by the rotation of the disc 12 producing three-phase currents which are supplied to a winding on a rotor 18 to produce a rotating magnetic field therein. The rotor 18 is mechanically rotated in the opposite direction by a shaft 26 and gearing 25, thereby rendering the magnetic field stationary in space. The rotation of the disc 12 is synchronized with the rotation of the rotor 18 by mounting the disc on the rotor. The magnetic circuit of the rotor 18 is completed by a fixed core 30 and a rotatable intermediate magnetic compass member 27 which sets itself in the direction of the stationary magnetic field. The direction of this field is varied by and follows any rotational displacement of the disc 11 by a shaft 39. The compass member 27 therefore also follows the movements of the shaft 39 and transmits the movement by gearing 28, 29 to shaft 40. The arrangements of the parts may be modified, for example the magnetic components may be reversed. Modifications may also be made to utilize single-phase instead of multi-phase currents. A large number of phases may be utilized.

Abstract: 740,376. Automatic voltage-control systems; exciting alternators. BRUSH ELECTRICAL ENGINEERING CO., Ltd. June 12, 1953 [Jan. 20, 1953], No. 1646/53. Classes 35 and 38 (4). In an automatic voltage control for an alternator in which an exciter is controlled in accordance with the difference between a reference voltage and the output voltage, frequency errors are cancelled out by introducing them into opposed control circuits. The field winding 1 of an exciter 17 is energized via rectifier 3 in accordance with the voltage across a saturable reactor 6 which is connected in series with a resistor 5 across the output terminals of the alternator. This voltage is substantially constant despite alternator voltage changes, but is frequency variable. The opposing field winding 2 is energized via rectifier 4 which is connected in series with a capacitor 7 across the output terminals of the alternator. The frequencyvariable components cancel, i.e. the resultant of winding, i.e. 2, is proportional to voltage error. In a modification, Figs. 3 and 7 (not shown), the rectifier 4 is isolated by a transformer 16 and the rectifiers 3 supply a single field winding. In a further modification, Fig. 2 (not shown), the series capacitor 7 is replaced by a shunt reactor. In a further modification, Figs. 4 and 5 (not shown), temperature errors are balanced by resistors in series, i.e. in shunt respectively with the windings 1 and 2.
