Patent GB-398947-A (GB)
Title: The manufacture of arylisothiazolones
Filed: 1932-05-03
Abstract: Arylisothiazolones are obtained by treating aryl - o - cyanosulphochlorides with metallic reducing agents in presence of a mineral acid and an organic solvent at temperatures below 60 DEG . The amount of reducing agent is such as to liberate four reactive hydrogen atoms per molecule of sulphochloride and the reaction is taken to such a point that a test fails to show the mercaptan reaction.  According to examples, 1 - methyl - 2-cyan - 5-chlor-benzene-3-sulphonic acid after conversion to the sulphochloride with phosphorus pentachloride gives 4-methyl-6-chloro-benz-isothiazolone-3, and 1-ethoxy-4-amino-benzene - 5 - sulphochloride (obtained by converting 1 - ethoxy - 4 - amino-benzene-5-sulphonic acid into the 4-cyano compound and treating with phosphorus pentachloride) gives 6 - ethoxy-benz-isothiazolone - 3, on treatment with zinc dust and hydrochloric or sulphuric acid respectively. Cyano-benzene-o-sulphochloride and naphthalene-2-cyano-1-sulphochloride are also specified and glacial acetic acid and other metallic reducing agents such as tin may be employed.  British Specification 319,075, [Class 2 (iii), Dyes &c.], and German Specification 216,269 are referred to.

Title: Improvement in method of making resin impregnated fabrics
IPC: B32B27/00
Filed: 1944-07-07
Abstract: 586,196. Resin coated sheets. UNITED STATES RUBBER CO. July 7, 1944, No. 12991. Convention date, Nov. 10, 1943. [Class 140] Woven or fibrous sheets or laminated sheets are impregnated with a reactive polymerizable resin which evolves heat exothermically on polymerization by applying the resin thereto, advancing the sheet between a set of spaced platens heated by circulating a liquid at controlled temperature therethrough to initiate polymerization and remove the heat evolved and then advancing the sheet between a second set of heated platens to harden the resin. The resins may be of the type described in Specification 540,938, [Group IV]. Other suitable resins of this type are referred to. As shown in Fig. 2 the sheets 10 the outer two comprising, if desired, woven fibre glass-cloth, are drawn over pulleys 13, 17 into a tank 14 containing the reactive resin 15 and a catalyst. The resultant sheet 16 passes by a wiper 19 to the curing apparatus shown In Fig. 1, paper sheets 28, 30 also moving through the apparatus to prevent contact of the tacky coating with the driven aprons 32, 33 of canvas or duck which move the sheets. The paper sheets 28, 30 pass to take up rolls 55, 58, the speed of movement being variable. The platens comprise fixed lower members 20<1>-23<1> and upper members 20-23 adjustable relative thereto by bolts 24 operated by hand-wheels 25 although the upper platens may rest directly on the lower. The platens are hollow and water at a temperature of about 200‹F. passes through the first two pairs of platens by means of inlets 43 and outlet 44 interconnecting pipes 49, 50 being provided. The pipes are connected to a thermostatically controlled water supply tank so that the platens, while initiating the polymerization are also maintained at contact temperature and in heatconducting contact with the sheet 16 to absorb the heat produced during the exothermic polymerization process. Platens 22, 22', 23, 23<1> are similarly heated to about 260‹F. by steam to hasten the first cure of the resin. Instead of a lamination, a single sheet may be impregnated with resin and passed through the apparatus.

Title: Hoist control mechanism
IPC: B66B1/52
Filed: 1947-05-14
Abstract: 627,788. Winding and paying-out apparatus. LOGAN, H. H. May 14, 1947, No. 13041. Convention date, May 17, 1946. [Class 78 (v)] A hoist control mechanism includes parts driven through reduction gearing from the hoist drum and provided with stops adapted to rotate a control drum only near the ends of the wind, rotation of the control drum from a predetermined position in either direction being arranged to operate controls for the hoisting drum. A shaft 17 is driven in accordance with the position of the hoist and, through gearing 22, 42 drives a pinion 45 on the shaft 40. Concentrically with the shaft 40 is rotatably mounted a drum 28 biassed by springs or weights to a preddetermined position and carrying cams 119, 120, 123, 124. The drum 28 carries internally a pinion 63 rotatable on a shaft 48 and meshing with the pinion 45. The pinion 63 is integral with a further pinion 64 meshing with a pinion 74 rotatable on an eccentric shaft 72 mounted within the drum 28. Thus on rotation of the shaft 17, the drum 28 is held stationary by its biassing means while the gears 45, 63, 74 rotate. When the hoist approaches one of the extreme stopping positions however, a corresponding stop 85 or 86 engages a bearing block 65 fixed to the drum, so that the drum and the gears 45, 63, 74 must rotate integrally with the shaft 40, so that the cams 119, 120, 123, 124 operate the motor and brakes. In moving away from the stopping place, the action of the cams is overruled by a manual control and when the hoist moves, the drum 28 returns to its normal position and is then held until the other extreme position is approached. The stops 85, 86 comprise shaped plates held by nuts on bolts the heads of which lie in a circumferential slot 82 of T-section in the gear 74 so that on loosening the nuts the position of the stops may be adjusted. An opening 84 permits the bolts to be inserted in the slots. The cams 119, 120 operate separate cam-followers which control the motor, each being effective at one of the stopping positions, while the cams 123, 124, operate a single follower to control the brake, each cam being effective at one of the stopping positions. All the cams comprise shaped plates adjustable on flanges 110, 112, 113 in a similar manner to the stops 85, 86 previously described. The drum 28 is biassed in the form shown by a cable secured to a yoke 95 on the drum and passing over pulleys (not shown) and supporting biassing weights. When the drum moves from its normal position the cable is wrapped about a groove 109 in the drum : the movement of the drum is less than a half revolution to either side of the normal position. Specification 501,933 is referred to.

Abstract: 1443479 Manufacturing semi-conductor devices SIEMENS AG 25 March 1974 [30 March 1973] 13071/74 Heading H1K An integrated circuit containing at least two F.E.T.'s having different conductivity states is produced by forming, on a surface of a semiconductor body containing a predetermined concentration of one type of doping impurity, a protective layer, e.g. of silicon nitride, having apertures formed therein by photoetching, covering the exposed surfaces of the body with a layer of a gettering material, e.g. thermally grown silicon oxide, and simultaneously and/or subsequently by selective gettering changing the concentration of the doping impurity below the gettering material but not below the protective layer, and forming an F.E.T. in a region of changed doping concentration and another F.E.T. in a region of unchanged doping concentration. The F.E.T.'s are of the insulated gate type and portions of the protective layer and the gettering layer may be used as masks in the diffusion process of forming the respective source and drain zones. The semi-conductor body may comprise a thick body of silicon doped with aluminium or boron; alternatively the body may comprise an epitaxial silicon layer on a silicon substrate or a silicon layer on a spinel or sapphire substrate. The thermally deposited silicon oxide getter layer serves to remove doping impurities from the underlying body, this process may be enhanced by subsequent heating.

In the construction shown in Fig. 2, the transducer elements 23<SP>1</SP> lie transverse and close to a flattened portion 22 of the line 21. They are joined together on one side of the line by a connection 23 which completes the secondary loop. The width of the ribbon 24 is equal to the diameter of the cylinder into which it is formed and the length 27 of the transition sections 26 is equal to half the width of the ribbon. The cylinder encloses a primary winding 32 on a ferrite core 31. In a modification (Fig. 4), the secondary is in the form of two semi-cylindrical loops 24<SP>1</SP> and the line 22 (not shown) is located on the axis of the cylinder. Transducer elements 23<SP>1</SP> are located transverse to and on either side of the line together with transitions 26<SP>1</SP>, the transducer elements separately complete the two loops of the secondary. The loops are insulated from each other by spacers 46 and the cylindrical secondary assembly is surrounded by an insulated primary winding. The secondary loops may be made by depositing copper on a flexible plastic strip, photo-etching the copper layer to obtain the required configuration and then bending the strip to a semi-cylindrical shape.

Title: A circuit arrangement permitting a check on the flow of current in semi-conductor rectifiers connected in parallel
IPC: H02H7/12
Filed: 1961-04-12
Abstract: 945,896. Transistor logic circuits. BROWN, BOVERI & CO. Ltd. April 12, 1961 [April 14, 1960], No. 13124/61. Heading H3T. [Also in Division H2] In a current converter including, for each phase, a number of semi-conductor rectifier elements 1 connected in parallel branches, the detection of non-conduction in a branch is determined by a first " and " circuit 4 which responds when current flows in every branch, this output being applied to a second " and " circuit 7 whose second input is derived from the total phase current, the output of the circuit 7 being zero only when the branches are all conductive. The inputs to the " and " circuit 4 are derived from current transformers 3 in the branches, these transformers having cores exhibiting a square hysteresis loop and D.C. windings to effect reversal of the magnetization. The transformers 3 provide a positive and negative pulse at the beginning and end respectively of the conducting pulse of the branches. The second input to the " and " circuit 7 is derived from a similar transformer 6. In one embodiment of the " and " circuit 4 (Fig. 4) transistors 8, one for each branch, are connected in parallel, have a common load 11 and have their bases biased by resistors 9, 10 connected between D.C. potentials +U 1  and - U 2 . The positive pulses from transformer winding 5 are applied to the bases rendering the transistors non-conductive. In the absence of any pulse due to failure of a rectifier element 1, the appropriate transistor conducts producing a pulse at the load 11. In another embodiment, a single transistor is used, the current transformer winding being connected in series with stopper diodes in parallel base circuits (Fig. 5, not shown). In a further embodiment, Fig. 6 (not shown), a series connection of transistors which is conductive when all the bases are pulsed is open-circuited should any base not receive a pulse from its transformer 3. The " and " circuit 7 may be similar to the circuit 4. In the event of a fault indication an automatic reduction in output current may be effected to avoid overloading the remaining elements. Since the arrangement requires a minimum operating current for satisfactory operation of the transformers 3, a minimum current relay may be included. To indicate which rectifier element has failed, glow discharge or incandescent lamps may be connected to each winding 5.
