Title: Improvements in or relating to miners' flame safety lamps and the like
Inventor: SMITH CLIFFORD NAYLOR
IPC: F21L23/00
Filed: 1950-05-30
Abstract: 691,922. Miners' lamps. NAYLOR, Ltd., J. H. Aug. 27, 1951 [May 30, 1950] No. 13425/50. Class 75(iv) In a miner's safety lamp in which an upper part having a glass 10 secured between upper and lower collars 11 connected by .spaced upright rods 12 is screwed on to a lower part including an oil vessel 13, unauthorized separation of the parts is prevented by a magnetically releasable concealed spring- loaded plunger 15 enclosed between the parts and disposed in line with one of the upright rods 12, this particular .rod 12a being of magnetic material. The lower collar 11 screws on to a. neck 13a of the vessel 13 and is provided with an aperture 14 which houses a spring-loaded locking plunger. 15 and into the top of which is screwed one 12a of the rods 12, this particular rod being of magnetic material e.g. steel. The reduced lower end of the plunger normally projects into a notch 17 in the vessel 13 to. prevent unscrewing of the parts, but may be retracted by electro-magnetic means. Movement of the plunger is limited by the engagement of a shoulder thereon with a lip at the bottom of the aperture. A de. pending flange 11a on the collar 11 surrounds the edge of the vessel 13 and thus prevents any insertion of a thin implement for tampering with the plunger. Alternatively, an upstanding flange on the vessel 13 may surround the lower end of the collar 11, or the abutting surfaces of the collar and vessel may be stepped to interengage with one another.

Patent GB-981472-A (GB)
Title: A method of forming bituminized sand
IPC: E02B3/12
Filed: 1963-04-05
Abstract: <PICT:0981472/C3/1> Bituminized sand is formed by partially immersing in water a tube or cylinder with its open lower end below the water level, forming and maintaining a movable bottom of bituminized sand in the lower region of the tube or cylinder, and supplying to the lower region, above the movable bottom, bituminous emulsion together with or followed by a slurry of sand and water.  As shown in the Figure, tube 1 may be suspended vertically, and may contain a ball float 4, which approximately fits the tube and which can move freely up and down therein.  The slurry acid emulsion may then be poured in, forming the movable bottom, and forcing the ball down until it becomes detached as at C.  The bituminized sand mass is, at hydrostatic equilibrium, arranged as in D, wherein, as the relative density of the bituminized sand is about 2, length b approximately equals length a.  At intervals an amount of bituminized sand becomes detached and sinks to the bottom 3. These intervals may be controlled by interrupting the supply of emulsion, whereupon a layer of non-bituminized sand forms, thus separating measured quantities of bituminized sand which become detached as they emerge from the bottom of the tube. Alternatively the tube may be closed with a valve to enable the movable bottom to be formed; or the upper end of the cylinder may be closed and the ingredients supplied by conduits.

Title: Improvements in or relating to the transport of aqueous emulsions of liquid explosives
IPC: F17D1/08
Filed: 1940-09-02
Abstract: 543,593. Water channels. BRYCE, G., WILLIAMS, V. H., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Sept. 2, 1940, Nos. 13716/40 and 8551/41. [Class 78 (i)] [Also in Group XXI] A method of transporting a liquid comprising an explosive nitric ester whereby a continuous line of explosive material between the sending and delivery stations is avoided, thus reducing the probability of communication of detonation, comprises timed intermittent syphoning operations from reservoirs disposed between the stations. The explosive runs by gravity from station A to a reservoir 2, where, after attaining a pre-determined level, it is syphoned by syphon 5 to a pipe 6 connecting the reservoir 2 to another reservoir 7. The rate of syphoning from reservoir 2 is arranged to be much greater than the rate of delivery to that reservoir so that a break of flow occurs at reservoir 2 and syphon 5 before the liquid explosive reaches the reservoir 7, whence it is syphoned to a delivery pipe 11 by a syphon 10 while the break still occurs in the reservoir 2, and pipe 6. The nitric ester may be in the form of an emulsion with an aqueous alkaline solution, and in this case the mixture is stirred by air bubbled through it from tubes 3 in the reservoirs, which are also provided with drainage taps 4.

Title: Improvements in or relating to methods of and apparatus for forming sheet glass
IPC: C03B13/04
Filed: 1926-05-31
Abstract: 261,627. Jackson, L. Mellersh-, (Hartford-Empire Co.). May 31, 1926. Rolling. - Relates to the method of making plate glass continuously in which a stream of glass from a spout 12 is flowed on to a receiving- roller 14 and against a sheet-forming roll 15, the spout being relatively narrow as compared with the finished sheet. According to the invention, the surface of the roll 14, instead of being cylindrical. is made convex with respect to its axis, and the surface of the roll 15 is correspondingly concaved. With this arrangement, the stream of glass spreads out more rapidly over the surface of the roll 14 instead of piling up against the middle of the roll 15, and the tendency to form ream and other defects in the finished sheet is reduced. The sheet 22 thus formed is curved in cross-section, and while still hot, it is passed between flattening rolls 23, 24. In a modification, the sheet is flattened by passing it over a table which is convex at its receiving end and gradually changes to a plane surface at its discharging end. A roller may be used to press the sheet against the plane portion of the flattening-table.

Title: Forage harvester
IPC: A01D43/08
Filed: 1971-05-07
Abstract: 1353646 Forage harvesters INTERNATIONAL HARVESTER CO 7 May 1971 [11 May 1970] 13774/71 Heading A1F Basic harvester unit 10 is adapted to support different removable attachment units by means of a linkage 59, 42 which serves as a parallel linkage in the attachment operating range but is arranged to tilt the attachment from the uppermost position of the operating range to a transport position. The unit 10 includes a torque tube 25 actuated by hydraulic jack 26 (Fig. 3) mounted in an operational unit 28 and actuated by a power source on a draft implement. Radial arm 36 (Fig. 3), pivotally connected to rod 34 of piston 32 of cylinder 30, is rigidly connected to torque tube 25 such that extension of jack 26 rotates rod 36 and torque tube 25 anticlockwise. Radial arms 86 (Fig. 6) rigidly secured to torque tube 25, and pivotally connected to links 88 are thus straightened with respect to one another, moving lift arms 42 in a corresponding direction thus lifting attachment unit 12. Lift arms 42 and link 59 are parallel, the links 59 being telescopic by means of slot pin 64, 66 but limited by engagement of edge 67c with pin 62 (Fig. 10). On exceeding a predetermined upward movement of attachment unit 12, the lower lifting link 42 (Fig. 6) engages with abutment surface 58 whereupon linkage 59, 42 no longer acts as a parallel linkage and lower links 42 swing about axis 54 with aid from adjustable springs 76 to tilt the units into a transport position. Springs 76 may be attached to various positions on the attachment unit 12 frame to provide for different harvester attachment unit weights by making use of different size lever arms. Jack 26 has a compression spring 40 (Fig. 3) providing a cushioning effect on lowering attachment unit 12, whilst on raising unit 12, an abutment arrangement provides for non- yielding jack extension. The spring and linkage arrangement provides a floating support for the attachment unit.

Title: Safety device for use with the steering gear of ships
IPC: B63H25/52
Filed: 1922-05-16
Abstract: 195,299. Tomlinson, A. V., (Sutphen, E. W.). May 16, 1922. No Patent granted (Sealing fee not paid). Steering-gear ; wrong movement, preventing. -Mechanism for automatically preventing wrong movements of the helm comprises a movable and a stationary surface co-operating with a wedging device, the movable surface being actuated by the signal transmitting gear. Means are provided whereby the helmsman may cut out this control when necessary. On the handwheel shaft 6 is keyed a disc 7, and there is also freely mounted on an eccentric boss 10 a member 11, Figs. 2 and 3. The member 11 carries a elotted extension 14 which engages a pin 15 whereby the member 11 is prevented from rotating. The opposed faces 12, 13 of the discs 7, 11, form a wedge race for a ball 19. The, eccentric boss 10 has a flanged rim 9 over which the telegraph cable 4 runs. On the actuation of the cable 4, the disc 11 takes an eccentric position relative to the disc 7 and the handwheel can only be turned, without wedging, in the desired direction. The wedge races may be shaped to give four-point contact with the ball, or the surfaces of the races and wedge may be ribbed or toothed. In a modification, wedge-shaped members are slidingly attached to one of the discs. In a further modification, a train of wheels carried by the eccentric disc brings a locking pinion into engagement with teeth on the shaft disc. Rotation in the correct direction acts to disengage the locking pinion but in the wrong direction the pinion is held hard.

Title: An improved safety device for use in connexion with sliding lattice gates
IPC: B66B13/24
Filed: 1936-05-15
Abstract: 464,171. Gates. SINCLAIR TOBACCO CO., Ltd., R., and FARRALL, W. May 15, 1936, No. 13845. [Class 45] [Also in Group XXX] To prevent a person's foot or other object from being trapped between the bars of the collapsable lattice gates of lifts, one or more plates are mounted pivotally on the gates to fill up the lower portion of the lattice when the gate is closed, and to turn up out of the way automatically as the gate is opened. Fig. 1 shows a single gate carrying two plates 3, each pivoted to a vertical member of the lattice at 2 and connected to each other at 5 by a pivot which carries roller bearings running in channelled guides 4 on a third vertical member of the lattice. Opening of the gate causes the two plates 3 to act as a toggle and force the pivot 5 upwards in the guides, thus folding the plates together. Two methods are described of applying the invention to gates having an even number of vertical lattice members. For example, if the gate in Fig. 1 is extended as shown in dotted lines to provide twelve vertical members instead of eleven, the plates would still be applied to the eleven members as shown, while the twelfth member would carry plates 8 slotted to pass over the pivots 2. In another construction for this purpose the channelled guide 4 is mounted between the two middle vertical members and carried by toggles connected to these members. Fig. 6 shows a modification in which a single member 13 pivoted at 14 is raised as the gate opens, by the engagement of a pin 15 on the gate with a slot 13a. For long gates two or more sets of plates may be used in the length of the gate. The weight of the plates may assist in closing the gate and maintaining it in the closed position.

Abstract: 310,204. Pothion, L. A. May 11, 1928. Re-railing devices ; mechanically operated by vehicle; spring control; point-tongues, mounting of.-To avoid derailment of vehicles through straddling the points, the heel of one tongue is spring-mounted and provided with a re-railing ramp, the tongue being forced home as soon-as the obstacle is removed. The tongue 3, Fig. 6, is engaged by a plunger 28 sliding in a bracket 27 under the action of a spring 26. Creep of the tongue is prevented by a bracket 30, Fig. 7, carried by the tongue and sliding between fixed plates 31, 31<1>, the lateral movement being limited by a stop 7, Fig. 1<b>. The ramp 8 is secured to the heel of the tongue and moves with it. The tongues 3, 4 are joined to scissor-bars 9 coupled by bars 11, 12 to a device 17. Bar 12 is guided by rollers 41, 42 which allow the bar to move towards tongue 3 on abnormal movement of the bars 9. Bar 12 is coupled to a crank 14, Fig. 4, carrying a roller 15 which engages a recess 16 and cam 22 on a plunger 17 provided with a spring-pressed nose 20 and two pawls 23 which lock the plunger in extended position. When a vehicle straddles the points, the heel of tongue 3 is moved in by the car wheels, which mount the ramp 8 and are guided on to the rail 5. This straightens the bars 9 which forces the plunger 17 towards the tongue 3. The following wheels will pursue the same path until the obstacle is removed when the nose 20 will force the tongue 3 home against its stock rail 1.
