Title: Scrap chopper
Inventor: O'BRIEN JEREMIAH WAGNER
IPC: B23D31/04
Filed: 1963-08-02
Abstract: 1,090,136. Shearing. UNITED ENGINEERING & FOUNDRY CO. July 22, 1964 [Aug. 2, 1963], No. 30705/63. Heading B3W. A shear for cutting up scrap resulting from an edge trimming operation comprises support means for a pair of co-operative knife holders, one of which is arranged closer than the other to the strip which is being edge-trimmed, at least one knife holder being movable to effect a cut, the axis of the holder closest to the said strip being arranged so that a continuation thereof forms an angle of less than 90 degrees with a plane perpendicular to the path of movement of the said strip. The shear comprises the following units. Edge trimming shear.-Two identical units 10 and 11 each comprise a pair of disc cutters 13 mounted on shafts 12 supported in housings 17. Each pair of shafts is interconnected and driven from a common unit 18. Each unit is mounted in guides on the base 23 and has a nut 25 which engages a lead screw 26, with left- and right-hand threads. so that the distance between the units may be adjusted by a drive unit 27. Scrap-cutter shears.-Two identical units 31 and 32 each comprise a housing 33 secured to a housing 17 and each supporting a pair of shafts 34 on which are mounted roller cutters 37 and 38, driven through gearing by a motor 42. The axes of the shafts 34 are arranged at an acute angle to the plane containing the axes of the disc-cutters 13. In a first modification Fig. 3, the scrap-cutters 53 and 54 have an orbital motion achieved by a double-crank construction comprising eccentrics 55, on which are mounted crank-arms 56 and 57 which are also connected to links 58 and 59 which are pivoted on the housing. The relative position of the cutters is adjusted by a hand operated worm 61 which rotates an eccentric on which the link 58 is mounted. In a second modification the scrap-cutter comprises a fixed blade and a roller cutter having two blades spaced 180 degrees apart.

Title: Improvements in time base generators
IPC: H03K4/32
Filed: 1946-10-15
Abstract: 632,434. Saw-tooth generating circuits. LAWS, C. A., and BUCKINGHAM, J. Oct. 15, 1946, No. 30715. [Class 40 (vi)] In a time-base generator for a magneticallydeflected cathode-ray tube, the deflecting coils are connected in series with the anode-cathode path of a valve to the control grid of which a rectangular voltage pulse is applied after amplification in a previous stage. The linearity of the saw-tooth current through the coils is improved by feeding back to the amplifier a voltage proportional to that across the deflecting coils. In the Figure a rectangular positive going pulse is applied to the grid of the amplifying valve V1 the pulse at its anode A2 being applied to the cathode follower stage V2 in the cathode of which the deflecting coils L are connected, the negative feed-back path through capacitor C2 correcting for non- linearity of the saw-tooth current through the deflecting coils. Diodes D1 and D2 limit the voltage swing in a negative direction of the grids of valve V1 and V2. The time constant of network C1, R6 is made very long and that of network 'C2, R3 short compared with that of the deflecting coil circuit in order to produce a steadily rising voltage across the coil. The effective feed-back voltage may be reduced by connecting the capacitor C2 to the junction point of two resistors R4, R5 connected across coil L. In a modification, Fig. 2 (not shown), the deflecting coils are connected in the anode circuit of the associated valve, thus preventing their being shunted by the low output impedance of the valve V2 during the flyback period. A negative going input pulse is used and the output of the amplifier is taken from the anode circuit of the first triode valve.

Abstract: 867,421. Controlling furnace operation. INSTITUT FUR WARMETECHNIK UND AUTOMATISIERUNG DER SILIKATHUTTENINDUSTRIE, W.T.I. Oct. 3,1957 [Oct. 3, 1956], No. 31061/57. Drawings to Specification. Class 51 (1). In an automatic regulating system for a furnace, all the variables required are measured in a model furnace proportionate with the main furnace in respect of size and specific thermal capacity which is fed through branch lines from the fuel and air supplies of the main furnace and the gas outlet of which leads into that of the main furnace, and the variables are kept constant in the model furnace by known regulators, and corresponding adjustments are made to the main furnace by devices controlled by the known regulators. The fuel and air supplies to the model and main furnace are maintained at a preset ratio, which may be automatically varied to compensate for minor disorders in the main furnace indicated by an additional measurement and control device, which may provide an alarm signal if serious disorders occur. Measuring devices in the gas outlets, particularly in the outlet from the model furnace, control the regulators to restore any deviations from an ideal value.

Abstract: 946,908. Dressing grinding wheels. ZAHNRADFABRIK FRIEDRICHSHAFEN A.G. Aug. 16, 1962 [Sept. 2, 1961], No. 31499/62. Heading B3D. The grinding wheel of a machine for splinegrinding is dressed by a device comprising a guide member pivotable through the spline angle and a diamond holder displaceable on the guide member in a radial direction parallel to the spline flanks wherein the same diamond is used for trueing the " base " curvature and the flanks of the wheel and is mounted so as to rotate and pivot respectively about two parallel axes spaced apart by a distance of R - b/2, (R being the " base " or bottom curvature radius and b the width of the splines), the trueing device and the tailstock of the grinding machine beng so disposed on a common base that the centre of the " base " trueing arc lies on the extension of the tailstock centre axis, whereby the flanks of the wheel and the " base " curvature can be trued in one operation centered on the longitudinal axis of the workpiece. Fig. 1 shows the sequence of operations of a diamond holder 102 for trueing the peripheral surface 2 and coned edge surfaces 3, 4 of a grinding wheel 1 for grinding the cylindrical and end surfaces of a spline; the successive positions of the holder 102 are shown by the numerals I, II, III, IV and V, the holder being swung through 90 degrees of positions II and IV for the correct positioning of the diamond 101. A somewhat similar sequence is employed for trueing two grinding wheels used in a spline grinding operation, each of the wheels thus having only one coned edge. The operating mechanism of the trueing tools is shown in Fig. 4, whilst Figs. 7 and 8 show a tool in positions II and III of Fig. 1 at the extremes of wheel-flank dressing movements. Rough and fine diamond tools 101, 101a, Fig. 3, are provided on a holder 102 for rough and fine trueing respectively, the complete unit being axially movable on a slide 140 between stops 138, 139 to bring the tools successively into the plane of the wheel. The cam-plate 115 is rotatable on a shaft 118 carried within a sleeve 119 in a support 120 capable of radial displacement by an adjusting spindle 123 whereby the radius R, Fig. 1, relative to the axis H is determined. The movements of the levers 111, 112, Fig. 4, are effected by the rotation of a plate 105 having shoulders 106, 107 which, striking a stop 108 in the plate 129 to which the tool-holder 102 is secured, permit a 90 degree rotation of the diamond to either side of the vertical. A spring-loaded plunger 117 maintains pressure on the rollers 116, 116a to hold them in alignment. A hand lever 135 is connected to a gear-wheel 133 which meshes with a pinion 132 on the end of the shaft 118 through which the device is operated.

The discharge may be through air-channels in and near the rotor blade roots, or at the periphery through oblique holes which direct the air downstream. Open-sided centrifugal impeller blades 22 formed on the shaft flange deliver part of their discharge within an annular lip 23 and so to the holes 21. The other part of the discharge passes outside the lip. Cooling passages in the blade roots are provided by slots 32, Fig. 4, closed by strips 33 or closed by deformation as in Fig. 6. The strips 3 are locked against endwise movement. According to the Provisional Specification the strips 3 may be wedge-shaped to assist, under centrifugal force, in tightening the blade root fastenings. Specification 628,036 is referred to.
