IPC: B25B23/145
Abstract: 1,095,495. Nut runner. DESOUTTER BROS. Ltd. July 21, 1966 [Sept. 10, 1965], No, 38682/65. Heading B3N. A pneumatic nut runner forming part of a multiple nut runner head, comprises a body 1, a head 2 fixed to the body and rotatable therewith in a manifold 8 due to the reaction to the applied torque, and a base 3 which is fixed to a baseplate 6 for the nut runners. The base comprises a lower part 13, Fig. 3, and an upper part 9 rotatable relative to part 13. An adjustable valve 26, Figs. 2, 4, is slidable in a sleeve 23 carried in a projection of lower part 13, and the valve is actuated by a screw 44 carried in a projection 38 of the upper part 9. Air is supplied to the motor in the body from conduits 50, 46, via a valve 54, Fig. 3, and valve 26 is supplied with air from conduit 46 through a pipe 35. In operation, the supply of air to conduit 50 is controlled by a master valve, so that the nut runners start together. The reaction to the torque applied to a nut by drive shaft 20, causes relative movement between member 9, 13. A spring 43, Fig. 2, is compressed, and valve 27 is moved so that air passes from pipe 35 into a pipe 33, and valve 54 is actuated so as to shut off the air supply to the motor. Each tool has an electric switch 60 operated by a spring 57, Fig. 3, which actuates a light on a control panel when the tool stops. The base may have two or more valves, so that they are opened at different values of torque.

[Also in Division C3] Coatings are produced on substrates, e.g. metal articles, by coating the article with a mixture of olefinically unsaturated monomers containing 10-90% by weight of at least one ester derived from an α, #-olefinically unsaturated monocarboxylic acid and a chlorinated and/or brominated monohydric alcohol, and polymerising the coating by irradiating with high-energy radiation at atmospheric pressure. Preferably, polymerisation is effected in the absence of solvents. The substrate can be coated by spraying, brushing, pouring, rolling, knife-coating, flooding or dipping. The specified ester monomer is preferably a chloro (or bromo) alkyl ester of acrylic, methacrylic, crotonic or cinnamic acid; the alcohol moiety may additionally contain a double bond or nitro group and the acid moiety may be halosubstituted (including, e.g. bromoundecenoic acid). The other component(s) of the monomer mixture may be, for example, (meth)acrylate esters, vinylbenzenes, unsaturated nitriles; vinyl esters, olefins, halogen-containing compounds such as halogen-containing unsaturated acids, unsaturated acyl halides and halogen-containing unsaturated amides, and compounds containing two or more polymerisable double bonds.

Abstract: 1,233,166. Washing gutted fish. H. F. H. SCHEIDING. 7 Feb., 1969 [9 Feb., 1968], No. 6891/69. Heading A2U. Gutted fish are first precleaned by being washed in a stream of water in a duct 16, which extends from an entry end 17 under a washing drum 10 and is then reversed through 180 degrees to terminate at the side of the drum at a wider but shallower zone 18, the fish on arrival at the zone 18 being elevated by an inclined endless conveyer belt 46 of wire mesh for transfer via a shoot 11 into the washing drum 10 where they are washed by sprays of fresh water from jets within the drum while the drum is rotated. The water leaving the drum is collected in a trough 27 and forms the source of supply of water to the duct 16, passing via an outlet 28 and side channels 30 to the entry end 17 of the duct. In addition, some of the water leaving the termination of the duct is recirculated by being collected in a trough having a weir 33, over which the main part of the water containing dirt particles and impurities flows, while the cleaner water is recycled by a pump (32, Fig. 1, not shown) and fed back to the entry end 17 via a pipe 35, an expanding duct containing diffuser plates (37, Figs. 5-7, not shown), and a strainer 38. The fish are introduced into the duct 16 via a shoot 23, and are agitated during their transport along the duct by inclined plates 42, preferably curved at 43, guides 44 being provided for vertical adjustment of the plates 42 to suitable positions in which they are fixed by screws 45.

Abstract: 1,250,438. Photo-electric measurement of temperature. UNITED STATES ATOMIC ENERGY COMMISSION. March 23, 1970 [May 26, 1969], No. 14006/70. Heading G1A. The temperature of a medium is measured by positioning a sealed transparent container partially filled with volatile liquid in heat exchange relationship with the medium, photo-electrically measuring the absorbance of the vapor in the container and obtaining the temperature measurement by reference to a calibration curve for the container of absorbance against temperature. The method depends on the fact that the vapour pressure within the container, and correspondingly the absorbance, changes with temperature, particularly with such volatile liquids as bromine, benzene, toluene and nitrogen dioxide. In the arrangement of Fig. 1, an incandescent lamp 10, provided with a reflector 9, prism 11 or fitter, and aperture plates 12 produces a collimated, mono-chromatic beam of light to illuminate container 3 located in contact with heat transfer medium 2. A photo-multiplier 13 and meter 14 measure the intensity transmitted by the vapour 6. In the arrangement of Fig. (not shown) the temperature inside a rotating centrifuge rotor is measured using a photo-electric system similar to that of Fig. 1, and by replacing one or more sample cuvettes by container(s) of volatile liquid. An individual calibration is required for each container or ampule and an example of such a calibration procedure is described. Liquid bromine is added to an ampule and is freezed during evacuation and sealing. Reference ampules are prepared, one evacuated and one containing phenol red dye solution. A static system calibration is performed and this verified in a spinning rotor using the dye-containing reference ampule as well. The output of the photomultiplier is monitored on an oscilloscope and recorded photographically. A calibration curve of log 10  absorbance against 1/T, Fig. 3 (not shown) is produced.

Abstract: 1,257,530. Insufflation apparatus. R. L. HESSE. 7 July, 1969 [8 July, 1968], No. 34111/ 69. Heading AST. An insufflation apparatus for artificial respiration or narcosis comprises a manually compressible pumping means including inlet and outlet connections 3, 4 with check valves 5, 6, the outlet being for connection to the air ducts of a patient, and a thin, gas tight, resilient membrane 1 forming part of the outer wall of the pumping means, the membrane being such that below a predetermined threshold pressure within the pumping means, the membrane does not expand, whereas a pressure above the threshold, possibly caused by a blockage in the patients ducts, causes the membrane to expand sufficient to prevent an increase in pressure above the threshold value. In the embodiment shown the membrane may expand to the line 11 to prevent increased pressure, the region 2 being thickwalled and resilient. Further pressure increase would cause further expansion in the directions. In a further embodiment the membrane covers a channelled insert, which insert is self-restoring, and provides a return to the reservoir capacity following compression. The membrane is free of the insert at points corresponding to the channels in the insert, and expands in these regions due to pressure increases above the threshold value. The maintainance of the pressure at or below the threshold value prevents damage to the patient which might otherwise be caused by high pressures.

The timer 118 is a monostable circuit whose unstable state may be adjusted by potentiometer 120 in accordance with the frequency to which the oscillator is to be set. In a first modification, Fig. 3 (not shown), the delay 117 of Fig. 1 is replaced by another monostable (325) and the timer comprises two monostables (318, 328) both with adjustable periods. This arrangement also has provision for the operating frequency to be given a sawtooth sweep by switching in a sawtooth generator (334). In a further modification, Fig. 5 (not shown), for applying a sweep to a C.R.T. in a frequency sweep test arrangement, the two limits of the frequency sweep are set by additional digital selectors (512A, 512B) which may be switched to the coincidence circuit (511).

Comparator 437 then resets bi-stable 436 to restore the circuit to its initial state.
