Abstract: 1487476 Two way transmission SOC NATIONALE INDUSTRIELLE AEROSPATIALE 24 Jan 1975 [18 Fob 1974] 3209/75 Heading H4R A peripheral unit is connected to a two wire line or to the wires of a four wire line for the transmission and reception of data in PCM form by a first circuit including a threshold circuit which provides a low impedance connection to the line during transmission, and a second circuit which provides a relatively high impedance for use during reception. As desscribed the peripheral unit is connected via transformer 33 and two parallel circuits to the two wire line 2, 3. One circuit includes parallel reverse poled rectifiers 5 which present a low impedance to signals transmitted by the peripheral unit, and a high impedance to signals of a level received from the line while the other circuit includes resistors 34, 35 which present negligible impedance shunt to the line but pass sufficient signals from the line to activate the receiver. The coupling circuit is enclosed in a screened box 45. In an alternative arrangement Fig. 4 (not shown) independent transmitters and receivers are coupled to the respective wires of a four wire line, the transmitter via parallel reverse poled rectifiers and the receiver via resistors.

Abstract: 114,023. Craig & Co., A. F., and Morfitt, F. March 14, 1917. Hulling, husking, and decorticating. - Relates to apparatus for depericarping palm nuts, olives, &c., and of the kind in which the nuts are fed on to a rotary drum or barrel, the pericarp being rubbed off and ejected by centrifugal force through surrounding members composed of a number of rectangular scraping bars mounted and supported in position between end rings so as to form a rotatable slotted casing or cage. The invention consists in the arrangement of a barrel provided with grooves in combination with a cage comprising an open framework provided with scraper blades. In the apparatus as shown in Fig. 1, the nuts are fed by a worm k from a hopper j to the rotary barrel a provided with grooves b which may be straight, angularly stepped, or helical as shown in Fig. 6. The nuts are thereby carried round in contact with scraper bars d secured to sectional rings i on a casing or open framework formed of annular and longitudinal ribs h, the pericarp being ejected centrifugally between the scraper blades and collected in a hopper under the machine. The cage or casing and barrel may both be driven manually or by power. The shaft l may be hollow to enable steam or other heating fluid to be introduced into the barrel a.

Title: Reproduction of sound
IPC: H04S3/02
Filed: 1971-02-02
Abstract: 1369813 Multi-channel stereo systems NATIONAL RESEARCH DEVELOPMENT CORP 11 Jan 1972 [2 Feb 1971] 3698/71 Heading H4R In a multi-channel sound reproduction system having two transmission channels and at least three outputs the signals in the two transmission channels are of equal amplitude and frequency but of phase difference related to the angle between the direction from which the sound represented by the audio signals is intended to be heard and a reference direction. As described the signals can be generated using three microphones located at one point. One microphone is omnidirectional and generates the first channel. The other two microphones have figure of eight directional characteristics, with their sensitivities following cosine law and oriented at right angles and their outputs are combined via a circuit giving 90 degrees relative phase shift, the resulting signal being of constant amplitude sensitivity but phase dependent on the direction of the source. At the reproducer the two signals are combined, and applied to four loud-speakers 49-52, Fig. 5, after applying relative phase shifts differing by 90 degrees between adjacent speakers. Additional speakers can be placed between any pair of speakers of the four fed with inputs derived from the signals fed to the adjacent speakers via networks (82, 86) Fig. 10 (not shown) which multiply the signals by cos and sin functions of the angle between the extra speaker and one of the adjacent speakers. An alternative circuit which gives better cancellation of signals originating from a direction at 180 degrees to the additional speaker is described with respect to Fig. 11 (not shown). Also described Fig. 12 (not shown) is an arrangement where the signals transmitted are the sum and difference of the signals used in the previous embodiments, which are said to be usable as left and right signals in a conventional stereophonic reproducer. An alternative transmitter arrangement, Fig. 3, uses a number of microphones 30-33 arranged around a sound stage, 34, and each feeding both channels via phase shifting networks providing a phase difference between channels dependent on the location of the particular microphone from which the signals are derived relative a reference direction.
