Title: Improvements in or relating to clampable integrating circuit arrangements
Inventor: MACDONALD JOHN BURNET
IPC: H03K17/68
Filed: 1962-10-16
Abstract: 984,348. Clampable integrating circuits. MARCONI CO. Ltd. Sept. 23, 1963 [Oct. 16, 1962], No. 39052/62. Heading G4G. A conventional integrating circuit including an input resistor 2 and a condenser 1 in series, with a D.C. amplifier 3 connected across the condenser, is provided with a clamping circuit consisting of two transistors, 6 and 61, of opposite type, connected in shunt across the condenser. To the bases of these transistors clamping voltage waveforms of opposite instantaneous polarity are applied. Clamping is utilised to short out the condenser when the integrator is not in use so that integration will start from a known reference point, and this particular circuit eliminates voltage steps at the amplifier input when the clamping voltage cuts off the single switching transistor of a conventional clamping circuit. It also provides fast clamping in both directions. Specifications 984,347 and 984,349 are referred to.

IPC: B23G9/00
Filed: 1958-12-09
Abstract: 853,650. Automatic lathes. HOLO-KROME SCREW CORPORATION. Dec. 9, 1958, No. 39621/58. Class 83 (3). A machine for trimming the opposite ends of rotating elongated workpieces such as sockethead screw-blanks, has workpiece-transfer and reversing-devices between the two chucks and between the second chuck and a point of discharge, a work-loader registering with the first chuck when the reversing-device is registering with the second chuck, a pusher-device for injecting the workpieces into the chucks, and ejectors for pushing the workpieces out of the chucks. Blanks are fed to a feed-collar 22, Figs. 1 and 3, through a gravity feed-tube 23, and are transferred one at a time from the collar by a transfer-arm B, with a pivoted gripping- member 12, to the first chuck C. A camoperated pusher E moves the blank into the chuck C and loads an ejector 86, Fig. 4, in the chuck spindle. A tool F, Fig. 3, on a lever holder 152, is then moved by cam-and-lever mechanism to turn the end of the blank now gripped by the chuck C. At the completion of this operation, a second transfer-arm 104 with gripping-fingers 107 is swung by rack-andpinion gearing to bring it into line with the chuck C. The preloaded ejector pushes the blank out of the released chuck-jaws into the fingers 107, and the transfer member 104 is turned back through 180 degrees to present the blank with its ends reversed to the chuck Cl. At the same time a new blank is delivered to the chuck C. The first blank facing the chuck C<1> is pushed therein by a pusher E<1> operated simultaneously with the pusher E, and this chuck is closed to rotate the work 20 for a turning- operation by the tool F<1>, this tool being movable by cam-mechanism, longitudinally as well as transversely. A third transfer arm 104<1>, identical with the arm 104 and moved by the same rack-device 105, removes the work from the chuck C<1> and turns through 180 degrees to bring it against a fixed ejector 111, from where it is collected. All the parts are driven synchronously by cams on a single cam-shaft G, Fig. 1, driven independently by a sprocket 181. The spindles 41 carrying the chucks are driven by belts 40, 401, and the chuck-opening and closing is effected by a single cam-operated crosshead 73 engaging grooves 72, 721, in the chuck-operating collars 64, 64<1>. The latter have a tapered bore 67, Fig. 4, which forces balls 63 down between a fixed collar 60 and a longitudinally-movable collar 61 secured to the collet-closing sleeve 58. The ejector 85, 86 is carried within the hollow chuck-spindle and has an adjustable loading-spring 90, which is compressed when the blanks are pushed into the chuck jaws.

An hydraulic shock absorber which has a substiantially linear energy absorbtion/ velocity characteristic and which is temperature independent comprises one or more through-flow valves 9, 10 for damping a fluid in which the, or each, valve comprises a seat 11 of very small annular width, e.g. less than 10% of the diameter of the valve seat opening 9, against which seat a valve body 11 is arranged to be pressed by a resilient member, and in which the valve seat opening forms a substantial constriction in the through flow duet and has a cross-sectional area so dimensioned that, at the highest calculated working speed of the shock absorber in normal operation the dynamic pressure drop in the gap between the valve body and the valve seat is between 75 and 99%, and preferably between 85 and 95%, of the total pressure drop in the throughflow valve. In this manner the, or each, through valve is provided in which the length of the through-flow valve gap in the direction of flow and the width perpendicular to this direction is as small as possible while the lift of the valve body is relatively great so that the energy absorbtion due to viscosity, which is temperature dependent, can be substantially disregarded and by far the largest part of the total resistance of the valve is due to the dynamic flow resistance in the valve gap. A suitable blow-off valve may be provided for exceptionally high flow velocities due to extreme overloading. Preferably as shown only one through flow valve should be provided for each direction of fluid flow. The valve body, in the form of a resilient plate 12 as shown, or comprising a spring-loaded ball, bears against the narrow ring-shaped seat 11 which is less than 1 mm. in width and is formed by providing a ring-shaped groove which is concentric with the valve opening.
