Title: Improvements in steady-rests for lathes or screw-cutting machines
IPC: B23Q1/76
Filed: 1923-10-06
Abstract: 226,753. Stenman, P. L. Oct. 6, 1923. Steady rests. - A steady rest for supporting a screw while being turned in a lathe comprises a support threaded to correspond to the size and pitch of the thread being cut and adapted to bear on the bottom of the thread so as to resist the thrust of the cutting-tools. The screw 100 is supported by two rollers 102 threaded at 103 and which, preferably, are positively driven at the same peripheral speed as the work by means of gears 104 rotated from some part of the lathe. As the cutting-tools increase the depth of the thread the support is moved nearer the workaxis by means of a cam or wedge.

Title: Improvements in or relating to automatic rewinding devices for webs of paper and thelike
IPC: B65H19/22
Filed: 1960-06-01
Abstract: 902,203. Winding webs. CHAMBON Ltd. June 1, 1960 [June 29, 1959; Aug. 4, 1959], No. 19380/60. Class 100 (1). [Also in Group VIII] A web 3 is wound on a mandrel 36 to form a roll 37, the mandrel 36 being supported in guide channels 34. The mandrel 36 closes a switch 46 when the roll 37 reaches a predetermined size. The switch 46 permits energization of a solenoid 18 upon closure of relay contacts 55b, Fig. 3 (not shown). The solenoid 18, Fig. 1, rocks a detent 16 to release a knife 9 which is rocked upwardly towards a rotary knife 8, thereby cutting the web 3. The leading end of the web is then fed by rollers 21, 22 to a drum 19 having perforations 19a. The end of the web is held to the drum by suction, within the drum, until it engages a mandrel 35 coated with glue and previously held apart from the drum 19 by a hub 38. Suction to the drum 19 is shut-off by a valve, not shown. The web then winds around the mandrel 35 driven by the drum 19. The mandrel 36 carrying the completed roll 37 is removed and replaced by an empty mandrel 36. When the roll on the mandrel 35 is complete the mandrel closes a switch 45 to permit energization of the solenoid 18 to initiate cutting the web by the knives 8, 9. Solenoids 43, 44 effect rocking of hubs 38, 39 to permit lowering of mandrels 35, 36 into contact with the drum 19. The solenoids 43, 44, 18 and a solenoid actuating a valve (not shown) connecting the drum 19 to suction are energized at the appropriate times through a control circuit, Fig. 3 (not shown). In another embodiment, Fig. 4 (not shown), two webs 73, 74 formed by longitudinally slitting a web 70 are wound into rolls on mandrels 75, 76 engaging separate perforated drums 79, 80 connected to suction.

Title: Improvements in methods of constructing concrete floorings and like surfaces
IPC: E04F15/12
Filed: 1938-07-01
Abstract: 516,401. Hardening concrete. BOULT, L. G. July 1, 1938, No. 19617. [Class 22] [Also in Group X] A method of constructing monolithic concrete floors and like surfaces consists in constructing a concrete base layer, adding to said layer, prior to the setting thereof, a liquid hardening-agent adapted to improve the wearing property of the concrete and a topping layer including cement, with or without an aggregate, and causing the topping to unite with or penetrate the surface of the base layer so as to form a monolithic structure. The base concrete may be applied to a bedding layer of graded rock or like material, with or without a layer of waterproof paper, felt or like material between the bedding layer and the base concrete. The liquid hardener may be that known by the trade name C.C. Premix." The topping layer may be applied to the treated base layer in dry form and may include granite or stone chippings, sand, or gravel. The liquid hardener is adapted to penetrate the upper stratum of the base concrete and also to hydrate the topping mix. The topping layer is treated by manual tamping or smoothing with suitable appliances until the mix is compacted integrally and uniformly with, or caused to penetrate, the surface of the base concrete. The base concrete may be tamped, prior to application of the topping layer, so as to facilitate the passage of water therefrom to the surface. After the surface has been treated in the above manner, the topped surface may be further treated, prior to setting of the topping layer, with a liquid hardening-agent. In some cases, the liquid hardening-agent is not applied prior to the application of the topping layer, but after the application of the topping layer ; the hardening-agent is; however, applied before the base concrete has set.

Title: Electrical counting circuits
Inventor: SHORT ALAN DONALD
IPC: H03K29/00
Filed: 1958-06-23
Abstract: 850,715. Electronic counters. NATIONAL RESEARCH DEVELOPMENT CORPORATION June 19, 1959 [June 23, 1958], No. 19998/58. Class 106 (1). A bi-directional multi-stage decade counting circuit includes a first gate between the nought recording element of a first stage and a second stage which passes a signal to increase the count of a second stage by unity, and a second gate between the nine recording element of the first stage and the second stage which passes a signal to decrease the count of the second stage by unity, and gate control means which opens the first gate only when the first stage reaches a count of nine and the second gate only when the first stage reaches a count of nought, the gates being closed when the first stage reaches a count of one or eight. As shown the stages of the counting circuit comprise decade cold cathode counting tubes P1, P2, each having cathodes K1 to K8, K9 and KO and two sets T1, T2 of transfer electrodes. Of the triodes shown, V1a, V2a and V2b, V3a are connected as trigger pairs and V1b and V3b comprise the first and second gates respectively. The cathodes Kl to K8 of counting tube P1 are coupled by resistors R1, R2 to the grid of V1a, and by resistors R11, R12 to the grid of V2b. The cathode K9 is connected by resistors R7, R8 to the grid of V2a and by capacitor C1 and resistor R9 to the grid of V3b. Cathode KO is connected by resistors R11, R12 to the grid of V2b and by capacitor C2 and resistor R14 to the grid of V1b. The anodes of V1b and V3b feed through capacitors C3, C4, a guide control circuit of the kind described in Electronic Engineering, Volume 28, No. 339 (May 1956) at pages 190 to 192, and which feeds the electrodes T1, T2 of counting tube P2. The gate valves V1b, V3b have common cathode loads with trigger circuit valves V1a, V3a respectively. When counting positively V1a is rendered non-conducting when a discharge invests cathode K9 of tube P1, which allows the gate valve Vlb to become conductive. V1a remains non-conductive until a discharge invests K1. When a discharge invests K0 the voltage output of the cathode is differentiated by C2, R14 and applied to the grid of V1b and thus through the anode to C3. The guide control circuit produces a negativegoing waveform at T1 of P2 and a delayed negative-going waveform at T2 of P2 thus shifting the discharge in the tube in a positive direction. In a similar manner when the counter is operating negatively, V3b is rendered conductive by the discharge at cathode K0 of tube P1 and transmits the differentiated output of the discharge at cathode K9 to C4.
