Title: Nut runner with reverse rotation brake
IPC: B25B23/145
Filed: 1966-10-07
Abstract: 1,127,962. Slip clutches; one-way brakes. CHICAGO PNEUMATIC TOOL CO. 7 Oct., 1966 [16 Nov., 1965], No. 44914/66. Headings F2C and F2E. [Also in Division B3] A rotary nut runner comprises a sliding vane air motor 23, Figs. 1, 1A, which drives the output spindle 38 through a double reduction gear 24 and a torque releasable clutch 25, 26, the member 26 being spring urged so that rollers 41 on part 25 are normally held in engagement with cam means 40 on member 26, and a brake means 68 to prevent the spindle 38 from rotating in the unscrewing direction. The stem 29 of lower clutch member 26 has a ball spline connection 33 with a hollow spindle 34, and the latter is splined to spindle 38 at 37. Brake means 68 comprises a one-way clutch which includes sleeve 69, Fig. 7, surrounding spindle 34 and held between a spacer 71 carried by the spindle, and a washer 72, spindle 34 being splined at 73 to sleeve 69. Grooves 74 are formed in the periphery of sleeve 69, and each is defined by a pair of arcuate shoulders 75, 76, Fig. 9, the former being of greater depth than the latter. A roller 77 is disposed in each groove, and registering with each groove is a radial opening 80 in sleeve 69, and a ball 78 is loosely disposed in each opening. A thin flexible split band 79 separates the balls from the rollers, and the balls are seated between a pair of opposed caned surfaces of rings 82, 83, Fig. 7, loaded by a spring 85. In operation, with clutch 25, 26 engaged so as to screw up a nut, sleeve 69 is rotated by spindle 34 with the balls and rollers 78, 77 in the Fig. 10 position wherein the rollers roll over the wall of a fixed bush 87. As the resistance of the work increases, rollers 41 of the main clutch move to the points M on cam 40, Fig. 6, and then ride over the crests 45 on to the back slopes 46. The residual energy of the motor following shut off is dissipated, and clutch spring 32 moves clutch member 26 axially to clutched condition and at the same time slopes 46 co-operate with the rollers, to rotate clutch member 26 in a reverse direction. This counter rotation is then transmitted to sleeve 69 until the rollers 77 are wedged against bush 87 in the Fig. 9 position, and the drive is braked.

Title: High vacuum metalling apparatus
Inventor: NORCROSS ERIC STANLEY
IPC: C23C14/56
Filed: 1963-11-15
Abstract: <PICT:1115601/C6-C7/1> Substrates of paper, plastics or fabric of natural or synthetic materials are coated by vapour deposition in vacuum apparatus comprising a housing containing a framework carrying pay-off, take-up, guide and drive rollers such that strip passes over two vapour sources 11, 12 whereby a coating is applied to each side or two coatings are deposited on one side.  The arrangement of the coatings depends on the path over the rollers, alternatively the strip may be twisted through 180 degrees.  The vapour sources comprise heating elements of graphite either rectangular or in the form of a trough, set within a cooled screening trough and other screens to limit the area of discharge, and supported between spaced cooled electrodes.  Tungsten coating material in wire form is fed to the heater, the wire end in contact with the heater being reciprocated along the length of the heater as described in Specification 1,101,072.  The strip can be moved at constant speed, its direction may be reversed, tension may be applied by braking the pay-off roller and to prevent creases the pay-off and take-up rollers are mounted on pivoting arms and maintained in spring-loaded contact with other fixed rollers.  In another embodiment the housing is divided into a coating chamber or chambers containing the heating elements and a main chamber containing the framework and strip which passes over exposure apertures in the dividing wall via rollers and a water cooled backing plate covering each aperture, alternatively the strip may pass on a large drum close to the aperture.  In either case the coating chamber alone is evacuated and the strip, forming only a partial seal between the chambers, permits the main chamber to be maintained at a reduced pressure.  A continuous or intermittent coating can be formed and by masking the aperture with bars the coating may comprise several strips.  The electric resistance and the dielectric strength of the strip may be measured using specially adapted rollers.  In the production of electric capacitor material a potential of 500v is applied to certain rollers which burns or removes any metal covering pin holes in the strip as it passes over these rollers.

Title: Improvements in or relating to programme controlled data-processing systems
IPC: H04M3/24
Filed: 1968-09-27
Abstract: 1,202,957. Data processing system. SIEMENS A.G. 27 Sept., 1968 [29 Sept., 1967], No. 45884/68. Heading G4A. A program-controlled data processing system is programmed such that in the event of failure of a functional unit, as a consequence of which a command in a control program can no longer be implemented the control program is modified to produce an equivalent command capable of being carried out by properly operating functional units. Instructions, having an address section capable of being modified by the contents of index registers are determined by an address held in command counter normally incremented by 1, are called to a command word buffer register and are applied to a decoder which, e.g. controls a multiplier for a specific control word. An automatic monitoring device detects whether any unit is malfunctioning and, if necessary, causes an interrupt condition to diagnose the fault. An interruption program then marks all commands referring to the faulty unit e.g. multiplication commands on the basis of the diagnosis. The main program is then returned to and when a marked instruction is reached an auxiliary program is jumped to which causes the command to be performed in an alternate manner, e.g. if the multiplier is faulty multiplication is performed by repeated addition, or if a register is faulty an alternate address referring to a different register is supplied, or a rapid operation requiring a small number of steps can be carried out on other units requiring a larger number of steps. At the end of the auxiliary program a return to the main program is initiated. The system is described as being used in a telephone exchange system.

Abstract: 1,131,325. Electro-chemical analysis. SVENSKA ACKUMULATOR A. B. JUNGNER. Nov. 2,1965 May 5, 1965 ] , No.46400/65. Heading G1N. In order to effect coulometric titration of a flowing medium the medium is vigorously agitated and caused to flow in an approximately helical path along the curved wall of a chamber first past the anode, then past an indicator electrode and a reference electrode, then through an outlet at the far end of the chamber and finally into contact with the cathode. In one embodiment liquid entering at 20 is forced by a rotating impeller 28 and helical baffle 26 to flow along the cylindrical wall of the chamber 18 towards the anode 36, and a combined indicator and reference electrode 41 before passing through a plug of glass wool 24 (or sintered glass discs, Fig. 3 (not shown) or ion-exchange diaphragms with by-pass passages, Fig. 4 (not shown) to the cathode 38 and outlet 22c. The volume of the chamber 18 is about 30 times larger than the volume of liquid passing through it per minute. In a modification, Fig. 6 (not shown) the cross-section of the chamber 18 is elliptical. In another modification, Fig. 7 (not shown), for analyzing sulphur dioxide in the form of a suspension of small bubbles in sodium sulphate solution, the chamber is separated from the cathode by a pair of ion-exchange diaphragms extending in parallel right across the cell. The anode and cathode may be made of platinum, gold, or silver, or the anode may be a platinum coil in a jet of sodium sulphate. The indicator - electrode may be of glass or of silver and the reference electrode may be of silver/silver chloride, or calomel, or of mercury sulphate and platinum. The power supply to the cell is automatically controlled as in Specification 1,131, 324 in which the working current is proportional to the difference between measured pH value and the butput of the reference electrode, hence, provided the flow rate is not too high the current varies in the proportion to the momentary concentration of reducible and oxidizable components in flowing medium.

Abstract: 1494914 Cultivating edible fungi LICENCIA TALALMANYOKAT ERTEKESITO VALLALAT 29 Oct 1974 [2 Nov 1973] 46721/74 Heading A1E A process for cultivating edible fungi comprises providing a comminuted growth medium of conventional composition, filling it into a cultivation unit having a wall of flexible organic material, the growth medium being inoculated either before or after filling step, with the mycelium of the desired fungus, allowing the mycelium to propagate throughout the growth medium which is held in the unit with limited access to air, then making at least one opening of sufficient size in said wall to create the usual growth conditions of the fungus. The cultivation unit may be tubular, about 20 cm. diameter and 80 cm. long, of transparent plastics, textiles or linenbacked rubber material which may be perforated for limited aeration. Mycelium inoculation is either by admixing the growth substrate and cereal grain germs before filling the unit, or, after filling, by placing a perforated tube in the growth medium, sterilising the whole unit above 100‹C, and threading through the tube a mycelium imprgenated organic filament, or by positioning an unperforated tube threaded through by such a filament heat-treating between 50‹ and 70‹C and removing the unperforated tube to leave the filament in the growth medium, or again a filament is pulled through the growth medium by a wire placed in the growth medium during the heat-treatment. The filled and inoculated units are sprayed with insecticide and stacked with their ends closed for mycelium propagation during about 32 days. Slits of 4-5 cm. are then made in the units wall to allow growth of the fungus.

Title: Write circuit for a phase modulation system
IPC: G11B20/10
Filed: 1966-10-20
Abstract: 1,137,572. Data storage. SPERRY RAND CORP. 20 Oct., 1966 [21 Oct., 1965], No. 47016/66. Heading G4C. In phase modulated recording e.g. when a change from positive level to negative level indicates a "0" and from negative to positive indicates a "1", two frequencies are recorded on tape. A lower frequency for a succession of alternating digits (101010 . . .) and a higher frequency for identical digits (1111111 or 00000) since the recording level has to alter in the middle of a digit period to allow the change indicating the digit to pass from positive to negative or vice versa. This causes bunching of some recorded signals and spreading of others depending on the digits either side of the one being considered. To overcome this the invention causes the signals that are read spread to be recorded bunched, and viceversa. Data to be recorded is applied to a 3 bit shift register 12. A decoder 14 comprising 4 AND gates samples the data contained and gives an output to OR gate 18 if the register contains 011 or 100 and an output to OR gate 16 if the register contains 110 or 001. The outputs from OR gates 16, 18 are applied to AND gates 28, 30 respectively and each to AND gate 20 via inverters 23, 21 respectively such that AND gate 20 is enabled if none of the signals 011, 100, 110, 001 is contained in register 12. The output of AND gate 20 is applied to AND gate 32. The AND gates 28, 30, 32 enable delay circuits 22, 24, 26 respectively which in turn enable AND gates 35, 40 to which the middle bit in register 12 is applied, via delay circuits 37, 39. AND gate 38 is enabled if the bit is a "1" and 40 enabled if the bit is "0". Thus a flip-flop 42 can be set and reset to apply the write signal to the recording head 44. Further AND gates 87, 83 are fed by the middle bit of register 1 and by a non significant clock (having pulses midway between the significant clock pulses) to change the recording level for series of identical digit recordings.
