Disk apparatus. - Consists of a cylindrical grinding machine having two heads with work-driving spindles, between which is carried the work, such as the crank-shaft of a motorcar. The heads 13 are each longitudinally adjustable on a swivelling table 12 mounted on a slide 10 that is movable along a bed 11. Each spindle is supported in its head by bearings of large area on each side of a toothed driving-wheel 21. The spindle is preferably of hard material, or has a sleeve of hard material, and the upper halves of the bearings, which are subject to wear, are provided with liners 32 of hard material, such as hardened steel, and are rigidly secured to the heads so that they form permanent guides adapted to hold the spindle in correct alinement when it is maintained in close contact with them. The lower halves of the bearings, which take the wear, are provided with liners 33<a> of soft material and are adjustable vertically by wedges 36 and screws 38, their movement being guided by slots taking over the square heads of screws 35. The adjusting-screws 38 may be locked by set screws 39 and plungers 40. Truly concentric collars 45 of the same diameter are formed on each end of the spinde; these may be used in conjunction with a gauge and the surface of the table 12 in setting the lower halves of the bearings. The spindles are driven from a shaft 26 extending along the table 12; at each end of this shaft is a wheel 25 in gear with a wheel 24 mounted on a feather on a short shaft 23 in each head and carrying a pinion in gear with the wheel 21. To take up wear of the teeth, the wheel 21 has secured to it, by pin-and-slot connexion, a correspondingly-toothed ring 31, which may be turned in relation to the wheel.

Title: Improvements in electron discharge valve amplifiers for pulses
IPC: H03K5/07
Filed: 1944-06-07
Abstract: 590,781. Pulse amplifying circuits. GENERAL ELECTRIC CO., Ltd., and ESPLEY, D. C. June 7, 1944, No. 10954. [Clasa, 40 (v)] In a circuit for amplifying negative pulses, the anode current of the amplifying valve is reduced over a major part of the interval between pulses by control means, compensating means being provided for reducing components introduced by the control means. A pulse generator 11, fed from a sine wave oscillator 10, delivers positive pulses to an amplifier V1, negative pulses from the anode being applied over a coupling condenser to the grid of valve V2. The phase-shifter 17, also fed from the oscillator 10, supplies a sine wave, together with a bias voltage to the potentiometer 16 from which a suitable potential is tapped off to a tuned circuit 14, 15 in the grid circuit of valve V2. The anode current 12 follows the sine wave of the grid input voltage, the phasing of the grid voltage being adjusted so that the negative pulse from valve VI occurs at the maximum of the anode current. The amplitude of the sine wave and the bias voltage may be increased, valve V2 then only conducting for a part of the cycle. To remove the components introduced by the sine wave, a series circuit 18, 19 is connected to the output of valve V2, or a more complex filter may be used. In a modification Fig. 4, (not shown), a potential from potentiometer 16 is applied to a biassed rectifier, the output of which is fed over an isolating resistance to the output load of valve V2, a further resistance connecting the load to the valve. The components introduced into the load of valve V2 due to the wave applied to the grid are cancelled by equal and opposite potentials applied through the auxiliary circuit. The control voltage applied to valve V2 may be of square or other waveform.

Abstract: 1,150,042. Sheet clamping; rotary duplicators. G. RITZERFELD. 9 March, 1967 [19 April, 1966], No. 11116/67. Heading B6C. A sheet-clamping arrangement in a rotary duplicating machine comprises two sheetclamping devices carried by the printing cylinder, each device having a clamp release member, and an actuating member movable between a first position for actuating one of the release members and a second position for actuating both release members. Fig. 2 illustrates a printing cylinder 1 having a set of clamping jaws 2-7; one clamp release member comprises a plate 28 carried on a shaft 8, which co-operates with jaws 4-7, the other clamp release member comprises a plate 29 carried on a sleeve 9 coaxial with shaft 8, this plate cooperating with jaws 2 and 3; the shaft 8 and sleeve 9 are individually rockable under the action of levers 26, 27 which carry rollers 24, 25. In use, an operating lever (17) (Fig. 2, not shown) causes actuating lever 23 to contact both rollers 24, 25 which through levers 26, 27 and plates 28, 29, open the clamp jaws 2-7 and allow a master sheet 16 to be inserted and placed on the cylinder 1; return springs (15) then close the jaws on the sheet. If a second sheet 31 is to be inserted, lever 23 is displaced axially on shaft 22 by means of lever 33 and is latched in this position so that when lever (17) is again operated, only roller 24 is contacted, and hence only clamp jaws 4-7 are opened, while jaws 2 and 3 remain closed on master sheet 16.
