Title: Improvements in and relating to devices for producing and/or amplifying high frequency electrical signals
IPC: H03B9/12
Filed: 1967-06-07
Abstract: 1192066 Semi-conductor devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 7 June 1967 [10 June 1966] 26300/67 Headings H3U UN U22 U30 U28 U34 U29Y and U29B [Also in Division H3] High frequency electrical signals are generated or amplified in a device comprising a single crystal 1 of a Piezo-electric semi-conductor material which is capable of exhibiting a bulk negative resistance effect (Gunn effect). The crystal includes a first transducer which converts supplied electrical energy into high frequency acoustic oscillations, a region of material across which is applied a strong electric field such that the acoustic oscillations transmitted from the first transducer in a direction parallel to the field are amplified, and a second transducer which converts the amplified acoustic oscillations back into high frequency electrical oscillations. The embodiment shown comprises a (110) orientated crystal of GaAs having Gunn diodes at both ends constituted by evaporated electrodes 2, 4 and 5, 7 respectively. The electrodes, which may be of binary or ternary alloys of Ag, Sn, Im, Ni or Au, are disposed perpendicular to the (100) axes of the crystal. The transverse acoustic wave propogated along the central region 12 is amplified by interaction with a D.C. field applied between electrodes 4, 5, and initiates Gunn effect oscillations in the second transducer, the output being taken from electrodes 5, 7. If the device is used as an amplifier the input signal is applied capacitively to the electrode 2. Several transducers, each comprising a Gunn diode (41-49), Fig. 4 (not shown), may be provided in series in a single crystal of GaAs, coupled by Piezo-electric amplification regions (50-57) in each of which the amplification may be just sufficient to counter the power lost in coupling the acoustic wave into the corresponding receiving transducer. The output from this device comprises a sequence of signal trains, produced by an initial pulsed signal train. In a further embodiment the crystal has three branches; one relatively short branch (64), Fig. 5 (not shown), lying in a (100) direction and containing only a single input Gunn amplifier or oscillator, and two mutually perpendicular (110) orientated branches (62, 63), each including an output Gunn diode (analogous to the diode 5, 6, 7 Fig. 1) and a Piezo-electric amplification region (68), (72) respectively. The regions (68), (72) are of different lengths so that the output signals produced at the two output Gunn diodes have differing phases. An alternative form of electrode consists of spaced pairs of diffused N-type regions (22, 23 and 24, 25), Fig. 2 (not shown), e.g. containing Te, Se or Si, on which are deposited electrodes (30-33), the electrodes being connected in pairs (30, 31 and 32, 33) to correspond to the electrodes 2, 4 shown in Fig. 1.

Abstract: 634,891. Seaming non-metallic sheet material. SHELLMAR PRODUCTS CORPORATION. Oct. 6, 1947, No. 26786. Convention date, May 3, 1943. [Class 42 (i)] [Also in Group XVII] The seams of a bag made from fibrous sheet material coated with heat-sealing or pressuresensitive adhesive are produced by piercing marginal areas to form openings containing numerous fibrous tentacles and by heat and/or pressure sealing together said areas when in face-to-face relationship, so that the adhesive binds the tentacles together and is dispersed throughout the aligned openings in the marginal areas and also between said areas. As shown, a web 11 of paper is adhesively laminated to a web 13 of grease-proof non-fibrous material to the lower surface of which marginal and spaced transverse stripes of any suitable adhesive are applied. The laminated web is passed between a pair of rolls 15, 16 which make numerous punctures in the areas coated with adhesive, and the web is then severed by knives 17 into blanks 18. Each of the latter is folded upon itself and the side edges are sealed to form a bag. In a modification the web 13 is dispensed with and the sealing adhesive is applied directly to the web 11. In a further modification the web 13 consists wholly or in part of rubber hydrochloride, in which case the application of sealing adhesive is not necessary.

Abstract: 702,838. Change-speed gear; frictiom clutches. BROCKHOUSE ENGINEERING (SOUTHPORT), Ltd. Nov. 5. 1951 [Nov. 3, 1950], No. 26829/50. Class 80 (2) To permit rapid disengagement of a friction clutch 26 or other apparatus engaged by oil pressure supplied through a line 30 to a rotating pressure space 28 containing an annular clutchactuating piston 27, in spite of the delay effect of residual centrifugal pressure, a pressure-responsive local exhaust-valve 35 is arranged in the supply line 30 to control supply and exhaust ports 32, 34, the valve-piston 35 being disposed in an axial bore forming a continuation of the outer periphery of the pressure space 28, exhaust from which does not therefore oppose centrifugal force. Application of pressure to the line 30 by a main torque-speed sensitive control valve 24 (as described in Specification 630, 675) moves the valve-piston 35 to the left against a light spring 37 closing the exhaust 34 and opening the supply port 32 to engage the clutch 26. On removal of pressure the valve-piston 35 moves back to the exhausting position shown, this movement being unopposed by virtue of a bleed 38 which relieves centrifugal pressure in the supply line 30. The change-speed gear shown, which incorporates the clutch 26, is that described, in Specification 639,675, wherein an output sun 23, which drives the load 25 through the torque-speed sensitive valve 24, is driven by way of a torqueconverter 10 of the overrun-reactor type, the turbine 12 of which is connected to a smaller sun 16 through an inner shaft 15. Both suns mesh stepped planets in a one-way detained planetcarrier 19, which for split-torque direct drive is driven from the input impeller 10 through the automatically engaged clutch 26. The gear and torque-speed sensitive valve may alternatively be as described respectively in Specifications 702,839 and 702,840 also referred to.

Title: 2-halogencycloheptene-(1)-carboxylic acid-(1) esters and their production
Inventor: MOELL HANS
Filed: 1959-08-06
Abstract: Esters of 2-chloro-cyclohept-1-ene-1-carboxylic acid and of the corresponding bromo compound are prepared by the action of an alcoholic solution of an alkali metal alcoholate on 2, 2, 8-trichlorcyclo-octan-1-one or the corresponding tribromo compound.  In Example 1, chlorine is led into a solution of cyclo-octanone in carbon tetrachloride; and 2, 2, 8-trichloro-cyclo-octanone is separated from the product by fractional distillation.  This trichloro compound is introduced into a solution of sodium methylate in methanol, and the mixture is boiled under reflux for 6 hours.  After acidifying the mixture with sulphuric acid, two layers are formed; and the upper oily layer is taken up in ether.  After removal of ether by distillation, the liquid is distilled under reduced pressure to give, first, suberone (by-product) and then the methyl ester of 2-chlorocyclohept-1-ene-1-carboxylic acid.  Example 2 describes the preparation of 2, 2, 8-tribromocyclo-octanone, and its conversion into the n-octyl ester of 2-bromo-cyclo hept-1-ene-1-carboxylic acid. Examples 3, 5, 6 and 7 relate to the preparation of the phenyl, benzyl, cyclohexyl and cyclo-octyl esters of the same bromo acid. Examples 4 and 7 relate to the preparation of the butyl and cyclo-octyle sters of 2-chloro-cyclohept-1-ene-1-carbcxylic aeid. The specification briefly refers to the conversion of suberone, by oximation and Beckmann rearrangement, into zeta-oenantho-lactam.

Title: A method of etching the surface of germanium
IPC: C23F3/04
Filed: 1957-08-30
Abstract: In a method of etching a surface of germanium the etchant consists of hypochlorite and an inhibitor in the form of germanium dioxide at a concentration between 0.1g and 0.6g/100c.c. and/or of carbon dioxide dissolved to its saturation point, for inhibiting the dissolution of the oxidized germanium and thus decreasing the preferential etching rate of differently oriented crystals at the surface.  Preferably the etchant contains from 0.01-5% of sodium hypochlorite, or enough of another hypochlorite to give an equivalent concentration of hypochlorite ions.  When carbon dioxide is used as the inhibitor, the pH of the solution is preferably 6.5 to 6.6.  As described, a constantly agitated 5% water solution of sodium chloride is electrolyzed by a D.C. of 5A. two graphite electrodes being immersed in the solution, to produce sodium hypochlorite, and carbon dioxide is bubbled into the solution at a rate of 1 litre or more a minute. The lapped germanium bodies are immersed in the solution during the electrolysis.  An etching rate of 0.6 m /min. is achieved at 40 DEG C. with a solution comprising 0.15% sodium hypochlorite and saturated with carbon dioxide.

Abstract: 1316462 Fig. 2 transmission systems LICENTIA PATENTVERWALTUNGS GmbH 5 June 1970 [6 June 1969 23 May 1970] 27389/70 Heading H4P Groups of binary signals are checked for error which if found in any group, causes that group to be inverted, then reinverted, either before or after transmission. The groups are transmitted in parallel. Incoming information is stored and circuits may be arranged for destructive or non-destructive read-out. Transmission channel 4 comprises a plurality of parallel paths, one for each bit, selectively connected to a store 1 directly or indirectly through an inverter 2 by a switch 3. The inverter may be omitted if a store giving anti-valent outputs is utilized. At the receiver an error checking device 6 causes switches 3, 9 to reverse on an error being detected, hence information which is still at present at the transmitter will be inverted, retransmitted and reinverted at the receiver. The method assumes that any error is one of accidental inversion hence by inverting incorrect information such errors are corrected and individual errors need not be traced. In an alternative arrangement, Fig. 2 (not shown), the groups are checked at the output of the transmitter and in the event of an error are inverted and reinverted before transmission by means of a circulating store of the non-destructive type. The arrangement illustrated in Fig. 3 (not shown) employs destructive read-out and has only one inverter but the groups are circulated twice. The storage arrangements are described in detail in the Specification.
