Title: Improvements in and relating to magnetic cores
IPC: H01F27/245
Filed: 1948-11-22
Abstract: 649,627. Transformers. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 22, 1948, No. 30321. Convention date, Nov. 25, 1947. [Class 38 (ii)] Relates to a high reactance transformer for use with two fluorescent lamps and comprising laminated core members 1, 2. The section of the leg 1 between yoke-legs 5, 6 carries the transformer primary winding, those portions between legs 4, 5 and 3, 6 mounting separate secondary windings. having leading and lagging currents respectively. In order to obtain substantially equal flux densities in legs 5, 6, the latter has the greater area. Notches 7, 8 are formed in the winding-leg to provide air-gaps, notches 9 being cut out of the member 1 to form gaps which are bridged by shoulders 10. In a modification (Fig. 2, not shown), the notches formed in the left-hand end of the winding-leg are off-set towards the centre of the core so that the shoulders which bridge the gaps make butt contact with the outer portions of the yoke-legs. This tends to prevent fluxleakage, to the metal case of the transformer, for example. The two secondary windings may each carry leading currents, the intermediate yoke-legs being of equal width. Bridged gaps such as 9, 10 are provided on opposite sides of each of the two ends of the core (Fig. 3, not shown). A core, otherwise similar to that of Fig. 3, may be provided with gaps at each end arranged as in Fig. 2 (Fig. 4, not shown).

Title: Process for the manufacture of water soluble compounds of indigoid dyestuffs
IPC: C09B7/00
Filed: 1928-10-19
Abstract: 324,119. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). Oct. 19, 1928. Indigoid dyes. - Water-soluble derivatives of indigoid dyestuffs are made by condensing indigoid dyestuffs containing a replaceable hydrogen atom attached to at least one nitrogen atom with a monosulphohalide of benzoic acid. The condensation is advantageously effected in the presence of an organic base. The products appear to be carboxylic amides containing free sulphonic groups, and may be used for dyeing or printing since they are readily converted into the parent dyestuffs on the fibre by the action of saponifying agents particularly alkalies. In examples (1) indigo is heated with benzoic acid m-sulphochloride in dry pyridine, the pyridine is distilled off, and the condensation product salted out with ammonium sulphate; the product is reconverted to indigo by dilute caustic soda at ordinary temperatures, while weaker alkalies, such as sodium carbonate, produce an intermediate compound, probably the monoacyl derivative, and (2) the condensation product from dibromisatin chloride and alpha-naphthol (Specification 7819/09, example A), subsequently brominated, is similarly treated with benzoic acid m-sulphochloride in pyridine. Other indigold dyestuffs, such as 5-bromindigo and 7 : 7<1>-dimethylindigo may be similarly treated, and other monosulphohalides of benzoic acid, such as the p-sulphochloride, may be used.

Dynamometers, rotary-transmission.-Relates to apparatus of the kind in which a driving shaft is connected to a driven shaft through intermeshing gear wheels mounted on several shafts and indicating mechanism is operated by a member rotating by the piston of the driven mechanism, and consists in a construction whereby an indicating member is rotated by friction of the driven mechanism without causing any bodily displacement of the driving or driven shafts. The member or casing 18 is provided with ball bearings for the shafts 12, 14 and for a countershaft 20 to which are secured two planet wheels 22, 24 gearing with wheels 26, 28 on the shafts 12, 14 respectively. The wheels 24, 26 are of equal size while the wheels 22, 28 are of equal size and bigger than the first pair. A weight 40 may be moved along a radial screw 42 in a plane passing through the axis of the shafts 12, 14 and through the centre of gravity to raise and lower the latter. The centre of gravity can be varied laterally to bring the pointer 34 to zero on the fixed scale 36 by moving a weight 44 on a tangential screw 46. In use, the weight 44 is adjusted to bring the pointer to zero when the motor 10 is running at constant speed thus compensating for internal friction and other inaccuracies. A speedometer or other mechanism to be tested is then connected to the squared end 16 of the shaft 14 and the angular movement of the casing which is a function of the torque being measured is indicated by the pointer. The sensitiveness may be varied by moving the weight 40 or by selecting appropriate gear wheels.

Filed: 1976-07-22
Abstract: 1536436 Memory system INTERNATIONAL STANDARD ELECTRIC CORP 22 July 1976 [28 July 1975] 30603/76 Heading G4A A memory system for connection to one or more processors via respective buses includes a plurality of memory blocks each formed by a plurality of memory modules one of which is a spare, and a plurality of controllers, one for each memory block, each controller having means to store the address of a module and data indicating whether that module is to be replaced by the spare module and means responsive to a memory address and the stored data to select the addressed or the spare module as appropriate. As described the memory has 4 blocks (2 address bits), each of 16 modules (4 address bits), each storing 16 pages (4 address bits) each of 512 words (9 address bits). Each controller is accessed by the block address bits to store the access request, and a circuit selects the highest priority stored access request, the module and page address bits of which access a lock memory storing read and write memory protection keys (which may be different) for each page in the memory block. The address and the data supplied to or from the memory are parity checked, any error in either memory protection or parity causing the controller to send an error signal. The lock data may be accessed and modified by processor commands which can also cause a module address (4-bits) and a reconfiguration bit to be stored in a memory 61 when one of the modules is to be replaced by the spare module. The appropriate 4 bits of an incoming memory address AD15-AD18 are compared, 62, with the stored reconfiguration address and if the comparison is positive C, if the reconfiguration bit indicates replacement S, and if the memory is not undergoing refreshing SELR, the replacement module is selected, Sp. Otherwise the addressed module S00-S15 is selected. An arrangement is provided, 66, which in the presence of a command bit DI12, exchanges the two halves of an addressed module by selectively complementing the highest order page address bit A19.

Abstract: 1,086,058. Cable grips; screw and nut gearing. FAIRY ENGINEERING Ltd. July 31, 1964 [Aug. 2, 1963], No. 30837/63. Headings F2Q and F2X. Sample carriers 12, 15 oscillating in an exchangeable nuclear reactor core void are attached to double cable loops 13 releasably coupled to a single driving oscillating cable loop 18 by a coupling 19 comprising, a block 60 in the cable loops 13 having spring-opened jaws 63 and a block 61 in the cable driving loop 18 adapted to be held by the jaws 63, which have overlapping tails 67 depressed by the block 61 when it is inserted between the jaws 63 so that the jaws pivot to embrace and hold block 61. The block 61 has edge channels 65 axially held and gripped by jaws 63. The jaws 63 are sprung by leaf springs 68 and pivoted at 66. When the jaws have been closed by the entry of block 61, a bolt 70 is shot by springs 77 into aligned jaw-tail holes 71 locking the jaws. To release the jaws a key 80 pushes the bolt 70 out of holes 71 until its reduced centre portion 83 lies in holes 71 allowing the jaws 63 to spring open. Whilst jaws 63 are open the key, which also starts the main drive motor, may not be removed from block 60. A ball catch helps to retain the key 80 in the block 60. Blocks 60, 61 are pivotally attached to the eyed-ends of cables 13, 18. The cable loops 13, 18 have tensioners 14a, 20a, one of which 14a is sprung. The driving cable loop 18 is driven from a rotatably oscillated drum 21 fast on a rotatable but axially restrained recirculating-ball nut 34 engaged by a reciprocating non-rotatable lead screw 32 integral with an hydraulic ram 28. The nut 34 has two parts 34a, 34b preloaded by contra-rotation to take up backlash, and runs in a fixed housing race 35. The lead screw 32 has longitudinal grooves 38 engaging with a re-circulating ball keying sleeve 40, Fig. 5. The ram is operated from a pump-fed hydraulic accumulator 50 through an electric servo valve 29 receiving signals from a remote control panel. Valves 52 relieve the pump when the accumulator shut-off valve 51 is closed. The cable drum 21 is electromagnetically braked at 54 and has an angular-position feedback potentiometer 57. An auxiliary hand and/or electric motor driving cable loop 23 (Fig. 3) is provided having a coupling block 61 for selective coupling to the block 60 in cables 13. Cable 23 is wrapped around a drum 90 driven by a motor 92 or hand wheel 91 with a revolution counter 93. Limit switches 96, 97 triggered by block 61 on loop 23 stop the electric motor 92 so that the carriers 12, 15 may be hand driven to a loading position. Switches 98 triggered by the coupling 60, 61 signal the limits of carrier travel to the control panel. The double carrier cable loops 13 are carried by pulleys 14 and the vertical portion carrying carriers 12, 15 is hung from an arm so that it is adjustable angularly and radially.
