Title: Method for making metallic structures from two or more selectively bonded sheets
IPC: B23P15/26
Filed: 1975-10-17
Abstract: In this metallic laminar structure, preferably comprising sheets of titanium or titanium compounds, the sheets are connected to one another in selected areas by welding, preferably diffusion welding, and superplastically strained in the other areas. For this purpose, layered sheets (10, 12, 14) are treated in the other areas (30, 32, 34) in such a way that welding cannot take place. Connection points for lines (72, 74) for feeding in an inert pressurised gas are formed by means of recesses (76, 77) and cut-outs (78, 79). After the welding process, air is extracted by means of lines (52, 60) from the cavities of the mould (44, 46) heated to the welding temperature and pressurised gas is forced into the laminar structure (10, 12, 14). The pressure in the laminar structure can be equalised by means of holes (96). This makes possible the welding and superplastic forming. Due to the fact that only one apparatus (44, 46) is used for both operations, the production time is shortened and equipment costs can be reduced. <IMAGE>

Title: Electrical synchronizing arrangements
IPC: H04L7/033
Filed: 1960-12-19
Abstract: 966,310. Automatic synchronizing systems. HASLER A.G. Dec. 19, 1960 [Dec. 19, 1959], No. 43644/60. Heading G3R. [Also in Divisions H2 and H3] Relates to a system for matching a periodic signal with another in phase, the system comprising a source E furnishing on line 11 a periodic signal, and an indicating device F for comparing and indicating phase difference between that signal and an output signal on line 10. The system also comprises switches Tb, Tc, which may be replaced by a phase discriminator comparing the phases in lines 10 and 11, and providing an error signal to gate G1 or gate G2 in accordance with the sense of the error. An impulse generator A produces two periodic sequences of pulse groups on lines 1, 2, said sequences having the same frequency but being offset in phase. The generator also produces separate sequences of periodic signal pulses-on lines 3, 4, having a predetermined time relationship with respect to the pulse groups on lines 1, 2. When switches Tb, Tc, are in the positions shown, gates G3, G4, are conductive so that the pulses on lines 1, 2, are fed to the flip-flop devices F3, F4, respectively, the output signals on lines 9, 10, taking a rectangular form at one-half the frequency of the pulse groups on lines 1, 2. To obtain synchronism when the signal on line 10 trails the reference signal E, switch Tb is actuated to render gate G1 conductive and the following pulse on line 3 switches a flip-flop device F1, F2, to its other stable condition. Gates G3, G4, are thereby rendered non-conductive whilst gates G5, G6, are rendered conductive to change-over the connections between -lines 1, 2, and devices F3, F4. The periods of the output pulses are thus shortened and adjusted towards phase equality with the reference signal on line 10. When the output signal leads the reference signal, the switch Tc is actuated to render gate G2 effective so that the following pulse on line 4 restores the flip-flop device F1, F2, to its former stable condition. This again restores synchronism.

Filed: 1969-09-04
Abstract: 1275098 Programme controlled exchanges STANDARD TELEPHONES & CABLES Ltd 25 Aug 1970 [4 Sept 1969] 43784/69 Heading H4K [Also in Division G4] The invention relates to a checking system for a memory e.g. used in a telephone exchange. Telecommunication system has a data processor provided with a memory subdivided into smaller memory blocks 1 - n, the number of blocks being greater than the number needed to meet the requirements of the system. The system has a logic block 1 forming control circuitry for the system, a programme store 3 and a memory failure control unit 4. Checks are performed during operation of the system and in the event of a fault a signal from the logic block 1 causes the control unit 4 to signal store 3 to cause diagnostic programmes to be successively fed to the memory blocks. The results of each programme are fed to logic block 1 and to control unit 4. If a number of blocks equal to the number required for operation of the system are diagnosed to be correctly working then these groups are selected and operation of the system recommences. If insufficient blocks are working correctly an alarm is given. If logic block 1 is faulty the diagnosed programmes will indicate that no memory blocks operate correctly.

Title: Process for the preparation of pure 1-nitroanthraquinone
IPC: C07C/
Filed: 1975-10-24
Abstract: Anthraquinone is nitrated with at least 85% strength nitric acid at temperatures of between -20 and +65 DEG C and molar ratios of nitric acid to anthraquinone of over 20:1. When over 50% of the anthraquinone has been reacted, the reaction is stopped by lowering the temperature to a value of below 20 DEG C and/or adjusting the mol fraction of the nitric acid to below 0.86. When the mol fraction is brought to a value of between 0.4 and 0.7 and/or the temperature to below 20 DEG C, 1-nitroanthraquinone precipitates and is filtered off and subsequently distilled in vacuo. In this manner, 1-nitroanthraquinone is obtained in a purity of over 99% without any particular process or safety aspects having to be considered.

Title: Nuclear reactor motor
Inventor: MOORE RICHARD L
IPC: G21D5/02
Filed: 1970-09-15
Abstract: 1,249,430. Controlling reactors. R. L. MOORE. 15 Sept., 1970, No. 43946/70. Heading G6C. In a cyclically pulsed nuclear reactor, mechanical power is produced directly by the generation of steam in the liquid fuel, the operation being simple harmonic. Cyclic operation is effected by formation of steam voids in the fuel which expand the fuel columns. After expansion, reactivity falls, the void volume decreases and the fuel volume contracts. A further reactivity control is introduced by control rods, the degree of insertion of which is determined by a centrifugal governor associated with the mechanical output shaft. The governor serves load charges, through the shaft angular velocity, but prevents the reactor pulsation drifting. The uranium sulphate fuel, dissolved in light water, is contained in the chamber 12<SP>1</SP> and the steam voids generated therein urge the piston 35 downwards, against the spring 48, to produce mechanical power at the shaft, 60. The piston is moved upwards by 48 as the voids collapse. The control rods 26, 27 are adjusted by the governor 63 coupled to the power take-off 60.

Filter rod elements supplied in a plurality of rows moving in an axial direction are manipulated so that the leading element of each row is removed from the row in a direction transverse to its axis and axially spaced from the leading elements of the other rows to form a new row consisting of the leading elements of each of the first rows. As shown in Fig. 1, filter rods of a first sort are cut on a drum 26 into three double length filter elements by cutters 30 and 31. These elements are removed axially from the drum, the elements from three adjacent grooves of the drum 26 being removed simultaneously, by one of a plurality of three-pronged projections on an endless chain 36, the three prongs engaging the three groves. The chain runs obliquely to the axis of the drum so as to take account of rotation of the drum during removal of the filter elements which are delivered to flexible tubes 44-46 connected to a transfer unit 42 (Fig. 3). During delivery of the elements the transfer unit 42 is moved by cam means to keep in register with the three grooves being emptied, after which it is returned to be adjacent to, and to move with, the next succeeding three grooves. The filter units in the tubes 44-46 pass to friction disc units 48-50 which deliver them to grooved discs 52-54 having different diameters. The discs 52-54 have a common delivery point to a drum 20 such that at this point the leading elements taken by the discs 52-54 from the tubes 44-46 are delivered in spaced axial alignment. These elements are combined on the drum 20 with elements of a second sort from a drum 17 and all the elements are aligned by guides 56 to 57. Tipping material from a drum 58 is applied and the composite rod assemblages are wrapped on a drum 70. In a second embodiment (Fig. 13, not shown) the cut elements of the first sort are delivered by the drum 26 into a fixed guide from which they are removed from one row at a time by a single pronged rake element to one of the tubes 44-46. In this case the transfer unit 42 is controlled by a cam so that each tube 44-46 is successively brought into communication with the fixed guides before the unit is returned to its original position.

Abstract: 441,974. Rolling. MEYER, E., 36, Aktienstrasse, Mulheim, Ruhr, Germany. May 13, 1935, No. 13951. [Class 83 (iv)] The pass of a rolling- mill 3 is kept constant automatically by a piston 1 under fluid pressure 4, so that if the rolling pressure increases, the fluid raises a piston valve 5 until outside pressure fluid is supplied through the valve 5 and bore 12 to the piston 1 which moves down thereby pulling down the rod 7 attached thereto and compressing the spring 6 which thereby depresses the piston valve 5 and restores it to equilibrium position between the ports 10 and 11. The initial compression of the spring is set by the nut 8. When the rolling pressure decreases the piston valve 5 moves down to open to exit port 11 so that escape of fluid therethrough allows the piston 1 to rise until the rod 7 diminishes the compression of the spring 6 on the valve 5 and allows it to rise again to restore equilibrium.

Abstract: 1496480 Splitting semi-conductors INTERNATIONAL BUSINESS MACHINES CORP 26 Oct 1976 [24 Nov 1975] 44530/76 Heading B5E [Also in Division B3] An apparatus for holding a semi-conductive wafer 11 to permit dicing of the wafer into chips 12 without dislocation of the sliced chips comprises a base member 15 having a surface upon which the wafer is received in use, an array of apertures 14 arranged in mutually perpendicular rows opening on to the surface, means for supplying a vacuum to the apertures, a coverplate 25 for pressing a wafer against the surface and having a plurality of parallel slots 28, means 30, 31 for precisely locating the cover-plate with respect to the base member, the spatial periodicity of the slots and the location of the cover being such that each slot extends intermediate two adjacent rows of apertures, the rib-like portions 27 intermediate the slots having resiliently compressible material 29 on the side facing the wafer receiving surface. The base member 15 is mounted on a bottom plate 17 and formed with a central cavity 18 which can be connected by a port 18a to a vacuum source and which communicates with the apertures 14 arranged in mutually perpendicular rows in a pedestal 16, the upper surface of which receives the wafer 11 to be sliced and is held on the surface by the vacuum acting in the apertures 14. The cover plate 25 can be accurately positioned on the base member by engagement of lugs 30, 31 thereon with holes 30A, 31A so that the ribs 27 between the slots 28 lie between the rows of apertures. Screws 34 secure the cover plate to the base member so that the resiliently compressible material 29, such as rubber, on the underside of the ribs is compressed to hold the wafer, and the chips formed when the wafer is diced, on the surface of the pedestal. Dicing may be effective by a saw 35 or scoring effected first with the cover plate in one position and then with the cover plate rotated through 90 degrees and positioned by the lugs 30, 31 engaging holes 30B, 31B. If the chips are not square but rectangular, a different cover plate may be used for the second dicing direction. In another embodiment, the wafer 11, Fig. 5, may be precisely located in the apparatus by engagement of a notch 11A in the wafer with a pin 61 on the base member 50 extending through an aperture 62 in the wafer mounting plate 53, the wafer being pressed against the pin by a pair of pins 65, 66 projecting from a manually rotatable axle 64 and extending through slots 65B, 66B in the plate 53. The wafer mounting plate 52 is positioned accurately on the base member by a plunger 60 on the base member engaging a side 52A of the plate to engage notches 58, 59 in the plate with lugs 56, 57 on the base member. The cover plate 20 is positioned on the base member by lugs 71, 72 engaging apertures 71A, 72A or 71B, 72B.

Abstract: 1,165,735. Photographic apparatus. NIPPON KOGAKUK.K. Oct. 10,1966, No.45111/66. Heading G2A. A camera shutter control comprises a drive means which is moved to a first position on activation and is delayed there by an electronic circuit, then, on moving to a second position, the drive means causes the shutter to open and after a delay determined by the circuit causes the drive means to move from the second position and close the shutter. As shown, the drive means is a spring-driven rotating cam-plate having upper and lower cams 10a, 10b and carrying a pin 11, which before activation holds open a switch S, in an electronic circuit. On release by a lever 14, the cam-plate turns and the switch S, closes, thereby energizing an electromagnet M which holds a stop-lever 26 in the path of the pin 11. A condenser in the circuit charges through a resistor and after a delay determined by the resistor passes a signal current to a transistor arrangement which de-energizes the magnet M, allowing the cam-plate to turn. Cam cob then abuts a roller 20 or a biased switch lever 17 thereby momentarily closing a swich S2 which causes the condense to discharge and the electromagnet to be re-energized. The roller 20 then moves along the edge of the cam-plate and closes switch S3 which causes the condense to recharge through a second resistor e.g. a manually variable or photo-resistor, to determine the exposure time, and simultaneously the cam 10a lifts a biased stop lever 22 which releases a lever 4 connected to the front blind of a roller blind shutter. The rear blind is also released but is held in position by a pin 8 which abuts the stop lever 26. When the condenser has again charged, the electromagnet M is de -energized, and the pin 8, and thus the rear blind, is released. The self-timer may be disengaged by operating a locking member 30 having a projection 30a which holds the switch S3 closed, thereby by-passing the delay resistor.
