Title: Improvements in or relating to transistors
IPC: H01L21/00
Filed: 1954-04-28
Abstract: 783,520. Transistors. PHILIPS ELECTRICAL INDUSTRIES, Ltd. April 28, 1954 [May 1, 1953], No. 12319/54. Class 37. A transistor comprises a semi-conductor body with a base electrode on one face and emittor(s) and collector(s) formed of impurity materials which are partly diffused into the opposite face to form PN junctions, wherein at least one of the emitters or collectors is in electrical contact with the body only at its periphery. Body 1 of N-type Ge (Fig. 3) with a base electrode 2 is formed with parallel saw-cuts 8 in its upper face upon which strips 9 of In, which in the complete transistor are alternately connected as emitter and collector respectively are melted. The cuts are partly filled with solid insulating material, e.g. SiO 2 , to prevent the In from filling then, PN junctions being formed on each side of the cut as shown (Fig. 4). Alternatively the In strips are fused to the surface on lines parallel to a series of long holes drilled just beneath the surface. In another modification a series of holes perpendicular to the base may be drilled downwards to extend as far as or right through the base electrode, and a blob of In fused to and around the top of each hole, the blobs being alternately connected as emitters and collectors. In all cases where the holes or saw-cuts open on the external surface of the completed device the junctions may be cleared by etching.

Abstract: 790,097. Friction clutches. ETABLISSE. MENTS E. JAEGER. April 27, 1956 [April 28, 1955], No. 12958/56. Class 80 (2). [Also in Groups XXXIV and XXXV] A magnetically engaged clutch or brake has a magnetic circuit including a shunt for the flux so that when the magnetic means is not energized and the clutch or brake is thereby disengaged, any residual flux passes through the shunt. The clutch &c. may be of the magnetic fluid, eddy current or friction type. A driving shaft 2a carries an iron ring 1a to which is attached by non-magnetic bolts 18a an annulus 5a with a non-magnetic washer 6a interposed between. A coil 3a is carried by the ring 1a. An iron disc 12a rotates with but slides axially on, a driven shaft 14a. On energization of the coil 3a, the disc 12a is drawn into frictional engagement with the ring 1a &c. The ring 5a is formed integrally with an outwardly directed flange 10a comprising the shunt. When energization of the coil 3a is low, i.e. less than that required for transmission of a substantial torque, the majority of the flux passes through the shunt. Thus any residual torque is reduced.

Abstract: 378,071. Melting cheese. SUTTER, E., 21, Oberburgstrasse, Berthoud, Switzerland. May 1, 1931, No. 12960. Convention date, May 28, 1930. [Class 84.] Soft cheese is melted gradually for moulding by placing it in a hopper 3 and feeding it by means of a worm 28 through a series of communicating chambers furnished with rotary stirring blades 20 and regulatable nozzles 23 for supplying steam, the chambers being interconnected by apertures, the size and number of which are varied in accordance with the fluidity of the mass so as to maintain a regular flow. A perforated cover-plate 33 of the hit- and-miss type is adjusted by a hand-lever 36 to regulate the delivery from the hopper. The temperature of the cheese gradually increases, as it traverses the compartments in succession, and finally it flows in liquid from down a shoot 37 to the moulds. The worm and stirring devices are driven from the gearing 7 in the base of the apparatus, which is actuated from a power shaft 4. The heating by direct admission of steam may be replaced by steam or hot water coils or other suitable appliances, also the material could be introduced radially through the side of the first chamber instead of axially from the hopper. The perforated plates between the chambers could be arranged to rotate, also the whole apparatus could be arranged horizontally instead of vertically.

Title: Improvements relating to methods and apparatus for reducing random variations in periodicity in a pulse signal
Inventor: BANDAT KURT
IPC: G10L25/90
Filed: 1965-03-29
Abstract: 1,093,102. Vocoder excitation function generator; pulse modulation systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 29, 1965 [April 6, 1964], No. 13166/65. Headings H4L and H4R. In a vocoder the excitation function, which is a series of pulses corresponding to unidirectional zero crossings of the fundamental frequency of the speech, is treated to reduce the effect of noise on the speech by deriving from the pulse train the mean value of the pulse spacing over a predetermined time interval and transmitting a pulse at this pulse spacing. The process is repeated for successive time intervals, each time interval commencing at a time after the commencement of the preceding time interval which is equal to the pulse spacing derived during the preceding time interval. The mean pulse spacing may be obtained by weighting each pulse spacing in the incoming signal in accordance with the time of occurrence of the pulse after the commencement of the interval, adding the weighted pulse spacings, and dividing the sum by a suitable factor. The Figure shows an excitation function generator for a vocoder in which the incoming speech is applied via a non-linear circuit NLG and a filter BP to a zero crossing detector ND and a pulse shaper IF to produce a pulse at every zero crossing in one direction of the fundamental frequency of the speech. The speech is also applied to a voiced-unvoiced detector D the output of which operates gates T1 and T2 so that during unvoiced sounds, when the excitation pulses are randomly spaced, the excitation pulses are fed direct to the output ANK<SP>1</SP> while during voiced sounds the pulses are fed to the units 1 to IV in order to derive the mean pulse spacings in accordance with the invention. The unit I comprises a device which measures the spacing between each pair of excitation pulses and stores these measured pulse spacings. The unit II then sums these pulse spacings over a measured interval, weighted in accordance with the time of occurrence after the start of the time interval if required, and divides them by the number of pulses, or some function thereof, to obtain the mean pulse spacing which is used in unit IV to generate the output excitation function pulse train. It is stated that the arrangement introduces some degradation into speech signals but may be advantageous under noisy conditions.
