Abstract: 848,241. Gripper mechanism. MASCHINENFABRIK AUGSBURG-NURNBERG A. G. Oct. 23, 1957 [Oct. 25, 1956; Dec. 20, 1956], No. 33092/57. Class 100(1) A gripper for use in a printing machine has a tongue urged by a spring into contact with an oscillatable support bracket disposed between the side walls of the gripper, the said gripper tongue being adjustable with respect to the bracket by means of a screw bolt which is arranged on the bracket between said gripper side walls. The bracket 6, Fig. 1, is fixed to a camoperated shaft 5 on a delivery cylinder 2 of a printing machine. The gripper 7, mainly of an inverted U-shaped cross-section, is arranged in a freely rotatable manner on the tube 5 so as to straddle the bracket 6 and rests on the head of a bolt 18 disposed in a tapped hole in a part 20 of the bracket 6, being biassed into contact therewith by a spring 8 disposed between the lower end of the bolt and a cross-piece uniting the legs of the gripper. The tongue of the gripper co-operates with an anvil 4 and the clearance between the two is variable to accommodate different thicknesses of paper at the same time keeping the length of the spring constant by screwing the bolt 18 up or down in the part 20, access to the bolt being provided by a hole 19 in the gripper. The bolt 18 is locked in set position by means of a bolt 22 which draws together the slotted ends of the part 20. In a modification Fig. 4, a bolt 9 having a wedge-shaped head 10 is disposed horizontally in a recess in the upper side of the bracket 6, passes through a hole in the bracket 6, and is engaged at the other side by a nut 11. The head 10 bears against an inclined surface 12 on the gripper and rotation of the nut 11 causes longitudinal displacement of the bolt and thereby varies the spacing between the gripper and the anvil. A spring 13 urges the bolt in the direction of the gripper tongue. In another form (Fig. 6, not shown) somewhat similar to that shown in Fig. 4 but without the parts 9, 10, 11, the part of the bracket against which the gripper 7 bears is separated by a slot from the main part of the bracket, and the width of the slot can be adjusted by a bolt, the head of which is accessible through a hole in the gripper.

Abstract: 619,080. Screw-thread gauges. BOOTH, C. H., and STOKES, C. Nov. 12, 1946, No. 33637. [Class 106 (ii)] In a screw-thread gauge of the kind in which a coil of wire is allowed to contract under its own resilience on to a thread to be tested, a cover is provided over one or each end of the coil with an access aperture in axial alignment with coil and through which a screw may be inserted into the latter, the aperture being such as to limit the maximum size of screw which can be inserted to that which will not give permanent deformation of the coil. As shown, a sector-shaped casing 1 has front and back plates 2, 3, a scale 6 on the plate 3, a window 4 in the plate 2, and a pointer 10, forming an extension of a coil spring. The coil has about 4“ turns and is positioned in a housing 8 formed in two parts 11, 12. One end 9 of the coil is anchored in the housing by a screw 17, and the other end passes through an aperture to form the pointer 10. The housing is rotatably mounted in the plates 2, 3 and has slots 15 therein for the reception of a key &c. The bore of the housing 8, wherein the coil is situated limits the maximum permissible expansion of the coil, and the end bores 19, 20 thereof one equal to the maximum diameter of a screw which it is permissible to measure. The coil can be expanded to facilitate insertion of a screw therein by depressing a lever 21. This lever is pivoted within the casing and extends through an aperture therein to provide a finger-piece 23 (not shown). On depressing the lever against the action of a spring 25 a lug 24 on the lever engages the pointer 10 to expand the coil. A master screw can then be inserted within the coil, the lever 21 released, and the pointer 10 adjusted to zero on the scale 6 by rotating the housing 8. The gauge can then, on removal of the master screw, be used to check other screws. The cross-section of the wire of the coil may be round or triangular. To check roundness of screws, part of the end turn of the coil may be inturned as described in Specification 619,079. In a modification, the means for rotating the housing 8 comprises a slot in the casing 1 around the housing through which a key may be inserted into a radial hole in the housing.

Abstract: 605,080. Gas turbine plant. ENGLISH ELECTRIC CO., Ltd., and STERLAND, E. G. Dec. 13, 1945, Nos. 33781/45 and 1298/46. [Class 110 (iii)] In a gas turbine plant comprising a useful power turbine and a turbine driving an axial flow or centrifugal compressor, each turbine being preceded by a combustion chamber and the turbines being arranged in respect of gas flow either in series or in parallel, a single control means controlling the fuel supply to both combustion chambers is arranged so that, on a diminishing load, the fuel supply to the power turbine combustion chamber is progressively reduced and that to the compressor turbine so controlled as to maintain substantially constant the inlet temperature to that turbine. Fig. 1 shows a plant with the turbines 5, 2 in series and in which fuel valves 4b, 3b a blow-off valve 8 and valves 9, 11 controlling direct admission of gas to the turbines are operated by cams on the shaft of a control lever 16. At full load, operating fuel is supplied only to the combustion chamber 4; fuel being supplied to the chamber 3 only in quantity sufficient to keep the burner alight. On a diminishing load down to about three quarters of full load, the flow through valve 4b is progressively diminished and the valve 3b remains closed. Further closing of the valve 4b is accompanied by an opening of the valve 3b until the valve 4b is shut. Further reduction in load is met by a closing of the valve 3b until the surging limit is approached and thereafter reduction in load is met by manipulation of the valves 8, 9, 11. In the parallel gas flow plant, the fuel supply to the combustion chamber of the compressor turbine is maintained whilst that to the power turbine combustion chamber is diminished. When the latter supply is at its minimum, further reduction of load is met by reducing the fuel supply to the compressor turbine and finally by means of the valves 8, 9, 11. There may be an additional thermostatic control of the fuel supply to the compressor turbine.
