Title: Improvements in or relating to voiced sound detection circuits
IPC: G10L25/93
Filed: 1961-12-29
Abstract: 1,008,565. Speech recognition systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 29, 1961 [Dec. 29, 1960], No. 46675/61. Heading G4R. [Also in Division H4] A voiced sound detection circuit comprises a clamped capacitor 74 (Fig. 2) coupled to receive electrical signals representative of the voiced sounds, the potential of the capacitor tending to the average value of the electrical signals, and a low pass filter 80, 81, 83, 84, 85 coupled to the capacitor 74 for deriving slowly varying signals representative of the characteristics of the voiced sound input. The circuit relies upon the asymmetry which exists between positivegoing cyclic components of the voiced speech waves and the negative-going components of such waves. The speech input signals are coupled through an amplifier 70 to a variable phase shift circuit including a resistor 72 and the capacitor 74. The capacitor 74 is clamped by oppositely poled diodes 76, 77. For discrimination of different voiced sounds the input signals may be applied to a filter 22 (Fig. 3) and phase shifter 23 before application to the voiced sound detection circuit 60. The phase shifter is adjusted empirically to provide discrimination between two voiced sounds (e.g. spoken " two and " seven "). A pulse sequence identifier circuit 62 includes a pulse splitter 64 consisting of parallel-coupled opposite conductivity-type transistors or oppositely-poled rectifiers to separate positive from negative pulses. The separated pulses are applied to relays 66 which control a switching network 68. For one adjustment, a negative pulse at the relays 66 gives a " nine " indication while a positive pulse followed by a negative pulse gives a " one " indication. For another adjustment, " three " and " four " sounds generate positive and negative pulses respectively. For recognition of a large vocabulary, various circuits using phase shift, with or without filtering, together with voiced sound detection circuits, may be used with a large set of selector relays and switching elements. Alternatively, logical gating networks may generate pulse sequences and distinguish different conditions.

Title: Improvements in Air-Conditioning Installations for Vehicles
IPC: B60H1/00
Filed: 1966-10-20
Abstract: 1,166,119. Ventilating vehicles. REGIE NATIONALE DES USINES RENAULT. 20 Oct., 1966 [21 Oct., 1965], No. 47105/66. Heading F4V. In a vehicle heating system air flows through the system either as a result of dynamic pressure conditions caused by the motion of the vehicle or by the action of a fan 14, the arrangement being such that the highest pressure is always available. Under dynamic pressure conditions, air enters a first chamber 4, opens a freely hinged shutter 7, passes through a chamber 5 to a heater 8 and is directed by a shutter 13 to the windscreen via a duct 11 and/or to the vehicle interior via a duct 12. If the fan 14 is used, air is drawn into the chamber 4, through the fan, and enters the chamber 5 to one side of the heater 8 passing through the heater to the vehicle interior. The fan pressure will tend to close the shutter 7. If, due to an increase in the vehicle's speed, the dynamic pressure exceeds the fan pressure, the shutter 7 will open permitting the highest air pressure to be utilized. The fan energizing circuit can be switched off automatically in response to movement of the shutter 7. A further shutter 9 controls the air input to the heater 8, and may be operated by conventional means.

Filed: 1976-11-16
Abstract: 1521209 TDM conference circuits INTERNATIONAL STANDARD ELECTRIC CORP 16 Nov 1976 [20 Nov 1975] 47677/76 Heading H4K A conference circuit for a PCM network whose frame time T defines m time slots of duration t comprises a store 3 for the non-linearly coded speech samples (codes), an expander 4 for converting the non-linear codes into linear ones, a linear summing circuit 6 and a compressor 9. The store comprises a read/write memory of m rows divided into K groups of I consecutive rows (m = K.I), each group corresponding to a conference, the m rows of the memory being written at the rate of one row per time slot t. During each time slot, the I rows of a group, including the written row, are read successively, with the memory being addressed in the period t/I. Thus, during the time slot assigned to a given subscriber taking part in a conference, the following occur: (a) the coded speech sample of the subscriber is written into a dedicated row of one group of the memory; (b) all the codes present in the rows of that group are read out successively; (c) all codes, apart from the subscriber's own, are summed at 6 and; (d) the summed linear code is converted to non-linear form at 9 and transmitted to the subscriber. An attenuation/noise suppression circuit may be located between the circuit 2 and the input and output buffers 1 and 30, Fig. 7 (not shown). This circuit attenuates both the codes at the input of those subscribers who are not speaking, and also the added codes at the output of those subscribers who are speaking.

Abstract: 478,714. Colour photography. LASSUS ST. GENIES, A. H. J. DE. July 23, 1936, No. 20432. Convention date, Aug. 1, 1935. Addition to 457,656. [Class 98 (ii)] In a modification of the lenticular film projection - printing apparatus described in the parent Specification, there is arranged, in order to permit of the original film facing the light source, beyond the original with respect to the objective, a screen identical to that specified in claim 4 of the parent Specification and constituting a uniformly luminous area, the screen being displaced with the original film and a shutter being arranged between the screen and the original film having a slot maintained, during the homothetic movement of the two films on the line joining their centres. As shown, AB, A<1>B<1> are the original and copy films and O the copying optical system. The auxiliary lens T alters the angular aperture of the elementary beams recorded on the copy film, the lenticulations of which may differ from those of the original. Another auxiliary lens may be placed between the optical system O and the copy film. The auxiliary lenses may be convergent or divergent. Where the lenticulations of the two films are not parallel, the relative linear movement is parallel to one of the bisectrices of the angle between the lenticulations. Where the lenticulations face the light-source, a diaphragm is arranged between the light source and the original film, with or without an additional spherical or cylindrical lens. Another additional lens is arranged near the other side of the original film to bring the zone of natural convergence into the plane of the diaphragm of the copying optical system. A moving slot is provided between the diaphragm and the original film. An additional lens may be placed near the copy film to modify the distance of natural convergence. With transversely lenticulated kinematograph films moving parallel the main and additional optical systems and the light-source are maintained stationary and the films are fed continuously with a speed ratio equal to the required enlargement. Opaque partitions may be disposed perpendicular to the diaphragms. If the distance of convergence is infinite, the moving diaphragms may be replaced by fixed diaphragms. An arrangement is described in which the main optical system comprises two coaxial members of variable spacing. The supporting frames of the two films and the objective effect synchronous angular oscillating movements of the same amplitude. Guides connected to the two objective members engage cam discs having their centres on the axes of the film frames. The light-source may be fixed or moved under control of a cam disc.
