Title: Methods and apparatus for relieving stress in metal parts
IPC: C21D7/04
Filed: 1949-03-14
Abstract: 676,295. Making saws; mechanically altering physical structure. HINDMARCH, T. May 19, 1950 [March 14, 1949], No. 6938/49. Classes 83 (ii) and 83 (iv). Hammering; power-hammers; rolling.-Stress in saws and other articles is relieved by mechanically hammering or pressing at spaced regions over an area with enough energy to relieve the stress without appreciable change in dimensions. A saw blade 4 may be fed by rollers 2 over an anvil 3 while acted on by a row of spring hammers 5. The operation may be repeated or the blade may be fed back and forward a number of times. The saw-teeth are not hammered. Each of the hammers may be operated by a cam 16, Fig. 3, which acts through a spring 18 to withdraw the head 5 against the action of a spring 20 which gives the blow when the cam passes its highest point. For softer materials rollers 25, Fig. 4, may be pressed against the work by fluid at the same or different pressures in cylinders 28. In another modification a circular saw 4, Fig. 5, is rotated with an anvil 3 by gearing 38 and operated on by spring hammers 5 as in Fig. 3, driven through gearing 43. If desired, the speed of rotation may be such as to prestress the work and thus assist the hammers in removing that undesired. In some cases the work is first heated and instead of using a series of rollers or hammers the material is pressed by means of a flat object, suitably heated if required. In other modifications one or more hammer heads and one or more roller heads may operate on the same piece of work simultaneously or successively.

Inking-apparatus.-Ink is removed from the wiping-strips of an intaglio printing-machine by means of a pad of absorbent material held in contact with the strip as it passes over a roller. The pad 32, Fig. 3, supplied with an ink-solvent from a container 55, is carried by a pair of arms 34 loose upon a sleeve 35 and is pressed against the wiping strip as it passes round the feed drum 27, by a spring 38 anchored to the sleeve and engaging a cross rod 40 between the arms 34. The sleeve 35 is reciprocated upon a shaft 36 by a crank and connecting rod receiving motion from a suitable part of the press. A roller 59 provided with ink-solvent from the container 55 may engage the strip in advance of the pad to effect a preliminary softening of the ink. Solvent and ink particles remaining on the strip as it leaves the pad 32 may be removed by a scraper 65 provided with a trough 6 leading by a pipe 67 to a container. This scraper is carried by pivoted arms 77 and normally pressed against the strip by a spring 78. To facilitate threading of a wiping-strip through the machine, a pair of bell crank levers 75 are provided on a shaft 70 provided with an operating handle 72. The forward ends of the levers 75 lie above a rod 76 connecting the arms 77 and a rod 73 connecting the rear ends of the levers lies adjacent the arms 34 carrying the pad 32. By turning the shaft 70, the scraper 65 and pad 32 can be moved clear of the drum 27. Adjustable side guides 88 guide the strip to the drum 27 and prevent lateral movement of the strip as the pad 32 reciprocates.

Title: Actuating device for oxygen regulator valve
IPC: A62B9/02
Filed: 1956-03-06
Abstract: 801,788. Valves. BENDIX AVIATION CORPORATION. March 6, 1956 [March 11, 1955], No. 7047/56. Class 135. A bellows 18, which has its ends soldered to an end cover 11 of an oxygen regulator body 10 and a slidable plate 19 in the latter, encloses a stop cylinder 45 and a spring 22 abutting the plate 19; a stem 25 fixed to the plate 19 and passing through the cover 11 embodies locking and setting flanges 26, 28 and, for setting purposes, is in two parts joined by a screw 29. Locking means in the form of a fork 32 hold the stem 25 and plate 19 in the inoperative position by straddling the stem 25, the outer ends of the fork 32 being lobe-shaped to facilitate insertion between the cover 11 and flange 26; in the locked position a stop 36 on the fork engages the edge of the flange 26. A locking pin extends through the fork arms and the stem. The fork is withdrawn from the locking position by a flexible metal cable 38. In operation, the locking pin is withdrawn and if necessary the fork 32 is shifted round the stem 25 to the most convenient position whereupon the cable 38 is then either pulled manually from any angle, or if attached to an aircraft is actuated upon operation of a pilot ejector seat, to withdraw the fork 32; the spring 22 then moves the plate 19 to open a conventional oxygen regulator valve 44, via a pin 43, the bellows 18 merely serving as a seal between a pressure chamber 40, intermediate the valve 44 and plate 19, and atmosphere. If the valve is a pressure regulator the oxygen released upon opening the valve 44 fills the chamber 40 and the interior of the body 10 and when the pressure rises to a given value the bellows 18 contract and release pin 43 allowing the valve 44 to close, the bellows being open to atmosphere by the clearance between the stem 25 and cover 11. The apparatus is returned to the inoperative position upon retracting the stem 25 by inserting a lever to engage the flange 28 and then replacing the fork. Retraction of the stem may also be effected by loosening screw 29, inserting the fork and then tightening the screw. The bellows may be omitted or replaced by some other pressure responsive element.

Filed: 1925-03-17
Abstract: 249,316. Siemens Bros. & Co., Ltd., and Berry, J. March 17, 1925. Automatic and semi-automatic exchange systems.-A clearing indicator at a manual operator's position is operated when an automatic subscriber hangs up by the application of alternating current for an interval determined by a mechanical timing device, comprising a rotating cam 10 controlling springs 11, 12, 13. Fig. 1 shows a trunk from a manual exchange terminating in a group selector at an automatic exchange, and having a special dialling jack JJ. Upon release by the called subscriber, relay Y falls back and prepares a circuit for a relay Z, which is completed over spring 12. The relay S locks over winding 2, connects up alternating current RG to operate the indicator RO, and prepares a circuit for a relay Z, which is completed over spring 13 and winding 3 of relay S. Relay Z locks and opens the holding circuit of relay S, so that it is subsequently released at spring 13. Line relay A is held at front contact s' to prevent release during this operation. Fig. 2 shows a trunk accessible from automatic switches and leading to a manual exchange. Relay N operates when the trunk is seized and connects its high resistance left winding to the test wire c. Ringing current RG is transmitted to operate the calling signal CL, a ringing signal being sent back from transformer RS, and when the distant operator plugs in, ring cut-off relay TR energizes, locks and connects up relay E. When the calling subscriber hangs up, relays N, TR fall back, and relay E is now held over the trunk loop. Relays S, Z energize in turn under control of the cam 10, as in Fig. 1, to operate the clearing indicator RO by alternating current RG<1>. Relay E marks the trunk busy during this time at open contact e<1>. Specification 233,859 is referred to.

Title: Handling machinery
IPC: B65B23/12
Filed: 1972-02-16
Abstract: 1394581 Packing machines J HANDLEY 7 May 1973 [16 Feb 1972] 7264/72 Heading B8C In a machine, for handling finger biscuits and other articles of pillar form suitable for multiple conveyance and packaging, and arranged to convey said articles in a succession of controlled groupings, each successive grouping is controlled, throughout its passage, by respective positioning equipment and positive transfer means is provided for transferring articles from each successive grouping to the next. As shown, in a machine for packaging finger biscuits the latter are advanced, side-by-side in a row, by a conveyer through an enrober which pours hot chocolate over them and then through a cooler, not shown, each leading set of biscuits, as shown, dropping from a spinner shaft, not shown, and into a compartment tray 1 which is in its raised position between the spaced chains of a conveyer 7, spring fingers 6 moving downwards to urge the biscuits into their respective compartments. The tray 1, which is axially slidably, but non-rotatively, mounted by arms 2, 3 upon a shaft 5, is moved quickly to the left as the spring fingers ascend, the biscuits being transferred from the tray 1 to the conveyer 1 immediately behind the last biscuit of the previously deposited row as the tray 1 descends below the conveyer C at the end of the transfer movement and the speed of the tray 1 being reduced, as it approaches its biscuit delivering position, to that of the conveyer C. An electronic-eye detector L signals to a counter E the actual number of biscuit fingers passing the detector L which initiates the downward rotational movement of a pusher arm F behind the last counted biscuit to move the picked set of biscuits over a dead plate G, on to two plates on a pair of pivoted arms H of a hatchway, and over a box I on a conveyer K. The two arms H are then swung outwardly so that the biscuits, assisted by the spaced wires on a spring-loaded pusher J as the latter is simultaneously swung downward, are positively placed in the box I. The hatchway arms H remain closed over the inserted biscuits while the pusher b is raised again so that the hatchway plates act to detach any biscuit sticking to the wires of the pusher J as the latter is withdrawn. The conveyer K is then stepped forward to bring the next box I to be filled beneath the hatchway H.

Title: Improvements in means for effecting the absorption of gases by liquids, or solutions, or suspensions, of solids in liquids
IPC: B01D53/18
Filed: 1924-03-21
Abstract: 233,490. Golding, H. D., Pritchard, J. W., and United Alkali Co., Ltd. March 21, 1924. Gases, treating with liquids.-In an apparatus for absorbing gases in liquids, the gas is supplied to a liquidcontainer beneath an open-ended cylinder arranged therein, and the pressure due to unabsorbed gas is utilized to control the supply of gas to the liquid-container. As shown in Fig. 1, an open-ended cylinder 11 is arranged within an open liquid-container 1 at the bottom of which gas from a cylinder 18 is introduced through a pipe 9, the gas being finely divided by a porous plate 7. An inverted hood 12 is arranged above the cylinder 11 and is carried by a rod 13 capable of vertical movement in guides 14, the rod 13 being connected to a lever 20 connected in turn to the valve 17 controlling the admission of gas, so that accumulation of unabsorbed gas in the hood 12 causes the rod 13 to rise and the supply of gas to be restricted. The gas supply pipe may be arranged to surround the cylinder 11, as at 9<a>, the expansion of gas within the pipe serving to cool the liquid. In a modified construction, as shown in Fig. 2, the container 1 is closed and is in communication with a chamber 30 through a pipe 31 which dips into the liquid in the vessel 1. A float 29 is arranged in the chamber 30 and is adapted to actuate the gas supply valve 17 when it is raised by liquid forced into the chamber 30 by the accumulation of unabsorbed gas in the chamber 1. With either of the constructions described a device may be combined adapted to prevent the entry of liquid into the cylinder 18 when the latter is exhausted. As shown in Fig. 3, this device comprises a vessel 23 containing an indifferent liquid and having a connection 9<c> to the gas supply pipe and a connection 24 to a chamber 25 containing a float 26. The float 26 carries a valve 27 adapted to close the air-inlet 28 to the chamber 25, the arrangement being such that air is drawn into the pipe 9<c> as soon as the pressure of gas in the cylinder 18 falls sufficiently to cause the float 26 to drop.
