Abstract: 1,051,759. Dynamometers. J.B. GARNETT. Aug.26, 1965 [July 29, 1964], No.30068/64. Heading G1W. A device for the measurement of stress in a structure made of a mouldable material such as cement concrete, comprises a rod 1 sandwiched between two blocks 2, 3 subjected to external forces of stress within the moulded structure, means for moving the rod 1 relative to the blocks 2, 3 and a device for measuring the force required to effect the relative movement, whereby the stress in the structure may be calculated. Two screws 8 hold the rod 1 between the blocks 2, 3 with a stress that can be predetermined and a jacket 12 of thin plastic sheet material prevents ingress of concrete from closing the gap between the blocks 2, 3. With the surfaces 4, 5 in direct contact with the concrete, the rod 1 is turned relative to the blocks 2, 3 by a torque spanner attached to an external extension 9 encased in a sheath 10 with inner U-shaped collar 11. In other embodiments a short rod is turned between plates by a wire wrapped round and attached to the rod and passing out of the structure through a sheath for connection to a tension meter or a sliding plate between static plates is pulled by a rod connected to a tension meter. In all embodiments the rod and blocks or plates may be of phosphor bronze or high strength steel and a lubricant with constant characteristics may be used between the rubbing surfaces. The co-efficient of limiting friction is constant over the range of pressures for which the device is designed so that the average concrete stress is proportional to the torque or tension measured allowance being made for any initial stress.

Abstract: 1,052,548. Friction clutches. DANA CORPORATION. March 15, 1965 [April 15, 1964], No. 10948/65. Heading F2C. In a spring engaged friction clutch comprising a driven plate 10 clamped between a driving flywheel 22 and a presser plate 28 by helical compression springs 54 acting through radial levers 42 pivoted at 44 to a back plate 24, the line of action of the springs 54 varies as the presser plate moves axially so that the resultant engaging force on the presser plate remains substantially constant throughout the stroke of the latter, to automatically maintain constant engaging force as the friction faces wear. Two parallel springs 54 act on each lever 42, each spring pivoting at the lever end on a triangular tab 70 bent out from the lever and engaging a cup 64 on the spring end, and at the reaction end on a diametrically opposite pair of projections 60 on a cup 58 received by the back plate 24. The outer end of each lever 42 is connected by a spring clip 50 to the head of an adjustment screw 36 in a lug 30 of the presser plate. A thrust sleeve (not shown) acts on the inner ends 56 of the levers for clutch disengagement. As the levers 42 turn clockwise, Fig. 2, the lines of action of the spring 54 recede from the pivots 42 so that the decreasing spring forces are compensated by increasing moment arms to give a substantially constant engaging load. In Fig. 5 (not shown) the lever positions A, B, C, represent the unworn engaged position, a worn engaged position, and the disengaged position respectively, the corresponding lines of action of the springs being E, D, and F respectively.

Feb. 28, 1968 [Dec.19, 1967], No. 9699/68. Heading G1A. Apparatus for analyzing liquids and gases by investigation of their absorption, fluorescence or scattering properties uses references and test photo-resistors and automatic zeroing using a reference sample. In the arrangement of Fig. 2 for absorption tests, ultraviolet radiation from a mercury vapour or deuterium lamp 21 is formed into a beam by condenser 22 and passed through an interference filter to beam-splitter 24. Part of the beam is reflected through adjustable diaphragm 27 to a photo-resistor 28 and the other part passes through, an absorption cell through which flows the liquid or gas under test, is reflected at mirror 26 back through the cell and is reflected from beam-splitter 24 to a further photo-cell 29, associated with a fixed diaphragm. The photoresistors are connected in a servo-controlled A. C. supplied Wheatstone bridge circuit as described in Specification 1, 057, 442. In an alternative arrangement, the mirror 26 is removed and replaced by the second photo-cell. In the arrangement of Fig.3, for fluorescence or scattering tests, the radiation transmitted by the beamsplitter is passed to a measurement cell which is provided with a window 40, through which passes either light scattered within the sample fluid or fluorescent light produced by the excitation of the sample by the indicent ultraviolet radn. This radiation is focused by lens 40 (through a filter 41, if fluorescent light is being monitored) to a photo-resistor 29a in a diaphragm. The photoresistors are connected to an A. C. bridge as before. Examples of substances which may be analyzed are given.

Abstract: 1,232,751. Sample loading device for liquid chromatography columns. TECHNICON INSTRUMENTS CORP. 15 Jan., 1969 [19 Jan., 1968], No. 2359/69. Heading B1X. Samples loaded in containers 10 located in concentric rows of apertures in rotatable table 12 are eluted successively therefrom on to chromatography columns (300, 302) (see Figs. 5 and 6, not shown) by causing the table 12 to rotate intermittently so as to bring two containers at a time between eluent inlet fittings 36, 38 and column inlet fittings 32, 34. When in place, the table 12 is lowered and push rods 94 bear down on blind bores 108, pressing the spring-biassed eluent inlets 36, 38 down on containers 10, and containers 10 in turn down on column inlets 32, 34. Eluent then passes through inlet 128, along bore 126, and into and through container 10, thereby eluting the sample which passes to columns (300, 302) along bores 134, 144. When elution is complete, push rods 94 are retracted, allowing inlets 36, 38 to rise, table 12 is raised and rotated until the next pair of containers 10 is located in place, whereupon the cycle is repeated. Sample containers 10 (see Fig. 7, (not shown) comprise ion-exchange resin (22) or other flow retarding material laden with sample located between porous discs (20, 24) surmounted, if desired or necessary, by insert rod (26) which allows a narrow annular space (27) for the passage of eluent. Details are also provided of the mechanical means whereby the indexing and rotation of the table 12, and the location in place of the containers 10 for elution of their, contents are achieved (see Figs. 1 and 3, not shown).

Abstract: 1,232,895. Injection moulding machines; extrusion machines. P. PONCET. 10 May, 1969, No. 23938/69. Heading B5A. [Also in Division B1] In apparatus for exposing plastic, granular or liquid material to a vacuum or treating gas, and for degassing and/or plasticizing it, the material is fed from a hopper 3 to the right hand end of a feeding screw 2 which compresses it, forming a gas-tight plug and feeds it through a passage 1g to the main degassing screw 4 where it is decompressed and stirred. The bores 1b, 1d have longitudinal slots communicating with a bore 1e which is evacuated or supplied with treating gas through conduit 8. Any material leaving screw 4 for bores 1d, 1e is collected by a circulating screw 7 and returned to the inlet end of screw 4. After treatment the material is recompressed by screw 4 and fed through passage lh to screw 5 where it is further compressed and discharged through radial bore 5d and ball valve 6. The outlet 1i may be open, or be fitted with an injection moulding nozzle in which case the screw 5 may be axially slidable and attached to the piston of an hydraulic ram which is gradually pushed back by the pressure of the material build-up between the nozzle and the outlet 1i, the ram being periodically actuated to discharge the material; the head 5c of screw 5 then acts as a piston. There may be two such discharge screws acting alternately. The screw 4 and/or its bore may be heated, and there may be cooling tubes in the bore le (9, Figs. 3 and 14, Fig. 5, not shown) or surrounding it (10, Figs. 4 and 5, not shown); the bore 1e may have rotating scrapers (12, Fig. 4 and 15, Fig. 5); and screw 4 may be cylindrical throughout, sealing being effected by screws 2, 5. In modifications for liquids fed and extracted by rotary valves or pumps, bore 1b has a lip (1k, Fig. 6, not shown), and bore 1e may be enlarged and have two recirculating screws (16, 17, Fig. 7, not shown). In other modifications, bore le becomes a chamber with a partition (1n, Fig. 8, not shown) and the slot between 1b and 1e is replaced by two passages (1o, 1p); the bore 1e may be reduced to vestigial nozzles (1q, 1r, Fig. 9, not shown); and the recycling screws may also be reduced to vestigial proportions co-operating with the nozzles (see Figs. 10 and 11, not shown).

Abstract: 1,233,232. Fuel elements. SOC. INDUSTRIELLE DE COMBUSTIBLE NUCLEAIRE. 14 Oct., 1968 [6 May, 1968], No. 48621/68. Heading G6C. A fuel assembly comprising a bundle of fuel rods 2 housed within a casing 1 and supported between two end grids 4, 6 has, within the casing 1, spacer grids 18 mounted at uniform intervals on the fuel rods 2. The spacer grids 18 are maintained in spaced relationship by suitable means on certain fuel rods 20. Each spacer grid 18 has a square frame formed by four plates 23 joined together by rounded corner brackets and provided with axial and transverse elongated slots 24 so as to permit free flow of the cooling fluid. Each pair of opposite plates 23 support, e.g. as by welding, two layers of parallel helical springs 28 to 31 which are tangent to the fuel rods 2. Adjacent layers extend in directions at right-angles to each other, the layers 28, 30 and 29, 31 extending in the same direction are relatively displaced by one half pitch, and the layers are relatively displaced along the fuel rods 2 in order that the springs are well separated from each other. In one embodiment, the helix of each spring has a pitch equal to the distance between the axes of adjacent fuel rods and is placed such as to be tangent at the summits to one row of fuel rods and at two intermediate points to the adjacent row. Each fuel rod is thus in contact with each layer of springs at three points. The force exerted on the fuel rods by the springs is sufficient to absorb the vibrations induced by the circulation of the coolant and also provides effective resistance to deformation caused by irradiation. The helices of the springs may alternatively have a pitch which is double the distance between the axes of adjacent fuel rods and have either a single point of contact with each fuel rod of the two rows of rods between which they pass or a point of contact with one fuel rod out of two.

The rotor comprises for equiangularly spaced tubes 15 arranged around a central horizontal tubular shaft 10 carrying stub shafts for drive purposes. A series of equispaced flanges 14 are welded to the shaft 10 and the tubes 15, and spacers 16 are located on the tubes 15 midway between alternate pairs of flanges. Flails 17 are fitted on the tubes 15 so that they follow a helical path around the rotor, each flail being mounted between a flange 14 and a spacer 16. Four cylindrical rods 18, each located parallel to a tube 15, serve as securing means for the flails 17, the rods passing through apertures 19 on the flanges 14 from one end of the rotor to the other. The rods 18 are lockable when a plate 20 engages a groove 21 in the rods, the plate being held in place by a nut and bolt 24, 22. The flails 17 are in the form of plates, having a blade portion 27 and a shank portion 26, the latter being in the form of an open loop fitting closely on a nylon sleeve 25 on the tube 15. When the rods 18 are locked, the flails 17 are free to pivot from position 17a to 17b (Fig. 3) through the normal operating position 17c radial to the axis of the shaft 10. The flails, the blade portions 27 of which are shaped as shown in Fig. 3, are arranged to have the cutting edges 29 of adjacent flails overlapping to avoid gaps, thus some of the flails are as shown in Fig. 2 and some have a stepped edge to one side. In other embodiments, the rods 18 can be omitted, making the tubes 15 removable to detach the flails, or the shaft 10 can be omitted.

At the start of the work cycle, the pair of wires 6a<SP>1</SP> are already in the position shown following a previous cycle, Fig. 2. The operator inserts wire pairs 4a, 4d in wire holders 100 and places a connector 28 in the pocket 120 of an arm 116, Fig. 4. The holders 100 are then rotated 90 degrees by an electric motor (72) via a chain (76) and sprocket (75), (78), drive, Fig. 5 (not shown), and the ends of the wires are trimmed by cutting edges 113 on a stationary cutter bar 126 cooperating with plates 108, 108<SP>1</SP>, mounted for rotation with the holders 100. As rotation continues, wire stuffer members 134a and shafts 158a are pivoted by cam follower rollers 170a engaging cam tracks (172) in end plates 64, 66, Fig. 7 (not shown). Thus wire separators 132a are advanced relatively to the stuffer members, thereby separating the wires and aligning them with the slits in the connector 28, Fig. 8A (not shown). The stuffer members 60, 62 are then advanced by a further camming action to force the wires through the slits into the slots of the connecting means 30, 32. The arm 116 pivots in the cutter bar 126 during the work cycle as the ends of arms 112a bear on the connector. The wires are trimmed and stuffed during the first 45 degrees of rotation and further rotation of the arms 112a eject the connector from the pocket 120, whereupon the arm 116 is returned by a spring (124), secured at one end to an ear 122 of the arm, Fig. 9B (not shown).
