Patent GB-349298-A (GB)
Title: Improvements relating to lifts associated with conveyors
IPC: B65G47/57
Filed: 1930-05-22
Abstract: 349,298. Endless belt conveyers; roller-way conveyers ; lifts. REED, E., of Newcastle Breweries, Haymarket, Newcastle-on-Tyne. May 22, 1930, No. 15788. [Classes 78 (i) and 78 (iii).] In automatically operated means for transferring goods from one conveyer, track, or runway to another at a different level of the kind including a vertically travelling cage provided with a tilting floor, the floor is hinged adjacent to that end of the cage at which the goods enter. When the cage is in its upper position, the floor m, Fig. 1, forms an extension of the roller-way conveyer a and is supported by the pivot n and a cross beam q. As the cage nears the lower limit of its travel, the floor m strikes a spring buffer w, Fig. 3, and the floor tilts about the pivot n into alignment with the roller-way conveyer a<1>. The tilting of the floor is limited by the engagement of a projection x on the buffer r with a stop y. In this position the box s slides out of the cage on to the conveyer. When the cage is empty, the weight v returns it to the upper position. The entrance to the cage is guarded by a gate c which is raised automatically by contact with a rod j on the cage as the latter approaches its upper limit of travel. In a modification the gate is raised by a spring trigger on the cage which is released by the incoming box striking the buffer r so that the gate falls and prevents the entrance of another box. The passage of the boxes down the conveyer a is controlled by a catch device. The cage may be provided with a pivoted lever which on contact with a stop strikes the box and starts its sliding movement on to the lower runway. The lift may be power-operated when it is desired to convey goods from a lower station to an upper one, and the free end of the floor may be suspended by links from a rocker arm pivoted on a shaft mounted at the top of the cage. The floor is tilted when the free end of the rocker arm strikes a projection at the upper station.

Patent GB-687017-A (GB)
Title: A wrong gas detector for use with an anaesthetic apparatus
Inventor: CARTER GEORGE
IPC: A61M16/10
Filed: 1950-06-28
Abstract: 687,017. Anaesthetic apparatus. EDMONDSON, W., and JONES, W. June 12, 1951 [June 28, 1950], No. 16082/50. Class 81 (ii). A wrong gas detector for use with anaesthetic apparatus is provided with means for differentiating qualitatively nitrous oxide and carbon dioxide from oxygen by means of pressure differences caused by diffusion, temporary pressure differences causing a permanent effect. In one form of the invention, Fig. 1, in which a visible warning is given, gas in the oxygen line flows into the detector through a nipple D, filter E and restriction F to surround a porous pot H containing silica gel. The interior of the porous pot H is connected with a compartment B fitted with a tube T communicating with a chamber C all of which contain-a deep-coloured liquid. If nitrous oxide or carbon dioxide is inadvertently connected with the oxygen line, the porous pot H becomes surrounded with nitrous oxide or carbon dioxide. Oxygen within the pot H diffuses out more quickly than nitrous oxide or carbon dioxides diffuses into the pot H so that a negative pressure is created within the pot H and the container B. This causes a rise of liquid in the pot B and a fall of liquid in the chamber C which exposes the words " wrong gas " on sleeve U. In another form of the invention, Fig. 2, in which an audible warning is given, a hollow structure is divided into five compartments, the top one x of which communicates with the interior of a porous pot 2 which may contain silica gel. This top compartment x is separated by a diaphragm W<SP>6</SP> from a compartment W<SP>8</SP> which is in communication through a duct V with the lowermost compartment A<SP>1</SP>, through a normally open valve W<SP>3</SP>, with the exterior of the porous pot 2 and through an opening W<SP>7</SP> with a compartment W beneath. The latter compartment W is separated from a whistle compartment S provided with a whistle-connecting nipple S<SP>3</SP> by a diaphragm S' which controls a normally closed valve A'. Gas entering the lowest compartment A<SP>1</SP> passes by way of duct V, opening W<SP>7</SP> and the normally open valve W<SP>3</SP> to surround the porous pot 2. If the gas is nitrous oxide or carbon dioxide a negative pressure is produced, by diffusion, within the porous pot 2 and the upper chamber x thus causing the raising of diaphragm W<SP>6 </SP>and the closing the valve W<SP>3</SP>. The resultant increase of pressure within the middle compartment W depresses the other diaphragm S<SP>1</SP> to open the normally closed valve A<SP>3</SP> so that gas can flow to the whistle compartment S to give an audible warning.

Title: Improvements relating to cutting or abrading tools
Inventor: OXFORD LEONARD GEORGE
IPC: B23D71/00
Filed: 1957-05-21
Abstract: 836,242. Making cutting-elements; forging; shearing; milling-cutters. SIMMONDS AEROCESSORIES Ltd. July 4, 1958 [May 21, 1957], No. 16093/57. Classes 83 (2), 83 (3) and 83 (4). [Also in Group XXIII] In a method of making cutting-elements, e.g. for cutting or abrading-tools of the kind formed from sheet-material by slitting the material transversely to the intended direction of cut and deforming it to bring one edge at each slit above the general level of the element, to provide a cutting-edge, each cutting-edge is formed by a punch which enters the material from the side opposite that which is to have the edges, and in a direction preferably perpendicular to its surface, whereby the rake-face of the cutting-edge is produced by a face of the punch inclined to its direction of movement. A strip of mild-steel 1 is thinned locally by a punch 2, the sheet being backed-up by a planesurface 3 and held down by pads 5, Fig. 1. The area 7, which is severely work-hardened, is then located over an inclined surface 15 of a die 12, Fig. 2, and is formed with a cutting- edge 16 by a punch 8, the inclined surface 11 of which hammers out the rake-surface 18 of the cutting-edge, while the front-face 10 shearsout a portion of the sheet. A number of cutting-edges with small projections, e.g. 0.005 or 0.01 inch, are produced in staggered relation by pairs of punches 2, 8 mounted on a single punch-holder, the sheet being fed a distance equal to twice the spacing of the edges before each working-movement. The material may be presented obliquely to the punches 2, 8. Punches with symmetrical-inclined surfaces may be used to obviate lateral forces, two edges then being produced, one of which is displaced back towards the strip (Fig. 7, not shown). Alternatively, punches and dies with two slightly asymmetric-inclined surfaces may be used so that one edge projects beyond the other, e.g. by 0.005 inch. The cutting-edge of Fig. 4 may be provided with depth-of-cut control surfaces as disclosed in Specification 836,051. The cutting-elements are subsequently hardened, e.g. mild-steel elements are casehardened by cyanide treatment. The cutting- elements may be flat for use with a backing- member for a hand-file, rasp, or plane. Elements may also be cylindrical or part-cylindrical, or of disc or conical form for use in rotary tools.

Title: A method and apparatus for testing the deflection of tyres for vehicles
IPC: G01L17/00
Filed: 1939-06-01
Abstract: 529,471. Gauging deflection of pneumatic tyres. DUNLOP RUBBER CO., Ltd., and DAW, R. F. June 1, 1939, No. 16146. [Class 106 (ii)] Comprises a device securable to a vehicle wheel for indicating the deflection of a pneumatic tyre, wherein said deflection is indicated by the displacement between the indicating members, one of which is operatively positioned by a ground contact and the other by a contact movable into register with an undeflected portion of the tyre tread. The device is secured to the vehicle rim by cam rollers 8, 9 carried by brackets 7 which may be slid along a bar 6 by turning a right-and-left handed screw 11 so that the rollers 8, 9 engage the parts of the rim as shown. The bar 6 is force fitted into lugs 13 formed upon the rear surface of a disc 14 the centre of which coincides with the axis of the wheel. The shaft 11 is rotatably centred between the lugs 13 by a sleeve 10 preventing lengthwise movement. To the front surface of the disc 14 is secured at 34 the vertical arm 15 of a triangular structure completed by a radial arm 17 and an interconnecting arm 16. The arm 17 has guides 20 for a round rod 21 bent at right angles at the end to form a tread contact 22. The other end of the rod 21 is connected by cable 24 passing over a pulley 25 to the top end of a rod 26 sliding in flanges 27 on the arm 15. A spring 28 is compressed between the lower flange 27 and a collar 29 threaded on the spindle 26. A scale plate 30 is secured to the rod 26 over which moves an index 32 attached to a rod 18 weighted with a knob 33 adapted to engage the ground, the scale 30 has a datum mark registering with the index 32 when the tread contact 22 registers with a correctly inflated tyre before the load is applied. In use the pressure is brought first to the correct inflation pressure. The structure is then clamped to the wheel and the contact 22 pulled out and rotated to contact under spring pressure with the tyre. The scale is thus moved correspondingly to a position representing an undeflected tyre. The knob 33 contacts with the ground while the pointer 32 moves along the scale when the deflection is read as a percentage of the undeflected height of the tyre. The device may also be used to enable any desired contact pressure to be obtained by varying the inflation until the correct deflection is reached.

Title: Improvements in or relating to buffing and draw gear for railway vehicles
IPC: B61G9/04
Filed: 1961-05-08
Abstract: 950,356. Railway vehicle combined buffer and draw gear. K. G. EMPSON. April 27, 1962 [May 8, 1961], No. 16666/61. Heading B7T. [Also in Division F2] A draft and buffing gear comprises a closed hydraulic cylinder 52, Figs. 2, 3, arms 44, 46 extending forwardly and rearwardly of the cylinder, rubber/metal sandwich buff and draw springs 74, 76 and movable compression plates 48, 50 supporting piston rods 56, 58 and a central main piston. In operation, the arms 44, 46 abut against end stops 16, 18, Fig. 1 (not shown), and hold the unit immovable within the vehicle centre sill so that on buff or draw loads one of the springs is compressed and the piston moves within the cylinder 52, which cylinder may have an internal surface which tapers from its centre towards the ends. In a modification, Fig. 4, the piston is provided with poppet valves 124, 126 carried by a sleeve 134 slidable within a cylinder 132, and a ring-shaped flange 136 on the sleeve, of slightly less surface area than the area of the end of one of the valves, moves as a piston within a cylinder 138 connected by ducts 140, 142 to the main piston faces. As the main piston moves in the cylinder under buff or draw load, the pressurized hydraulic fluid in advance of the piston acts on the poppet valve and moves it towards a closed or throttling position. At the same time, however, the pressurized fluid is conducted to the rear of the flange 136 to provide a nearly counterbalancing force in opposition to the force tending to close the valve. The sleeve is normally maintained in a centralized position by means of springs 139. The buff spring 74, Figs. 7, 8, comprises spacer plates 100, and concentric spaced rings of rubber moulded through holes in a mounting plate 90. The spring may, however, be formed without spacer plates and with rubber on one side only of the plate 90. Figs. 5 and 6 (not shown) illustrate a similarly constructed but stiffer draw spring. Shear pins 146, Fig. 3, which break off when the gear is first operated, are provided to hold the unit in a pre-compressed condition for initial fitting into the yoke.
