Title: Improvements in or relating to loading apparatus more particularly for vehicles
Inventor: WARD FREDERICK SYDNEY
IPC: B60P1/36
Filed: 1949-11-11
Abstract: 693,560. Loading vehicles. WARD, F. S. Feb. 12, 1951. [Nov. 11, 1949] No. 29006/49. Class 78 (iv). Apparatus for facilitating the loading of articles into vehicles, aircraft and storage chambers comprises a pair of load-carrying rails disposed near the top of the vehicle, &c., a cross-bar supported by and movable along the rails from which the goods are suspended, and means for lowering the cross-bar when it is at the back of the vehicle, &c. to facilitate the attachment of the goods and for raising it to the level of the rails. A pair of storage rails is provided above the load-carrying rails on to which the cross-bars are run when not in use. The goods are hung on hooks 31, Fig. 3, mounted on a cross-bar 26 which is supported at each end in a wheeled carriage 27. The hooks may be secured to the cross-bars by screws or slidable thereon. The rollers of the carriage run in channels 18 mounted on the loadcarrying rails 16. Pivoted extensions 24, Fig. 2, of these rails bridge the gap between them and a pair of lifting rails 39 which are raised and lowered by hydraulic rams 37. A rod depending from each rail 39 is slidably mounted in the corresponding ram and is forced upwards by a spring, the strength of which is such that when an unloaded cross-bar is carried, the member 39 is forced upwardly as far as it will go. This upward movement is limited by a pair of rods 41, the upper ends of which are secured to the member 39 and the lower ends of which pass through brackets on the ram head 38 and carry stop members 44. Springs 45 may be provided to reduce shock. Each rail 39 can be locked in contact with the head 38 by a pivoted latch 46, The rods are of such length that when the ram is in its fully extended position and the latch is released, the rail 39 will be in the same plane as the storage rail 17 and its pivoted extension 25. In addition to the doors at the rear, the vehicle is provided with a sliding inner door, which may be of the flexible metal type, to exclude dust during transit. The door slides in channels 20, 21 which are connected by curved sections 22. These sections are hinged to the vehicle at 23 so that they can be swung to a position 22a which permits the extensions 24, 25 to be swung into position in line with the rails 16, 17.
Patent GB-290436-A (GB)
Abstract: 290,436. Thornton, W. M. May 5, 1927. Pressure gauges.-An electrical instrument has a conductor heated preferably electrically and operating by reason of the cooling effect of a unidirectional or alternating electrostatic field in which it is placed. The cooling effect depends on the pressure of the gas surrounding the heated conductor, the instrument therefore serving to measure gaseous pressures. This effect is probably due to the movement of electrically charged molecules of air at the surface of the treated conductor. In the construction shown in Fig. 1, a high-tension electrode is formed by a rod A contained in an insulating sheath B and terminating at its upper end in a knob or terminal to which connection mav be made. The sheathed electrode is supported on a hollow insulator C- mounted on a base D, the lower portion of the insulator C forming a chamber containing a small filament E, having a high temperature coefficient, which is enclosed in a bulb filled with air or gas at any desired pressure and connected to terminals F. Fig. 2 shows the connections for measuring an alternating-current voltage. The high-tension electrode A is connected through a switch L to one end of the secondary winding G of a transformer supplying a load M connected to earth through a switch L<1>. The heated conductor E is earthed and forms one arm of a Wheatstone bridge. The conductor E is heated to a dull.red when no voltage is applied to the electrode A and the resistance H<1> adjusted until the galvanometer K reads zero. When voltage is applied to the electrode A the conductor E is cooled, causing a deflection of the galvanometer K, which may be calibrated in voltages. Alternatively the variable resistance H<1> may be adjusted to give a zero indication, and may be calibrated in voltages. The electrode A may be a dished member partly surrounding the filament E and not sheathed with insulating material. The heated conductor E, instead of forming one electrode of the electrostatic field, may be placed between the two electrodes of that field. The high-tension electrode may be formed by the end of the high-tension cable, which is sealed into an insulating container and supported in the insulator C, Fig. 1. The chamber at the bottom of the insulator C may be made gas-tight and the bulb enclosing the heated conductor E omitted.

Title: Apparatus for controlling gas pressures
IPC: H01J61/28
Filed: 1936-10-26
Abstract: 481,918. Discharge lamps; discharge apparatus. BARKON TUBE LIGHTING CORPORATION. Oct. 26, 1936, No. 29045. Convention date, Oct. 25, 1935. [Class 39 (i)] [Also in Group XXXV] A supply of gas for regulating the pressure in an electric discharge lamp or other gasfilled apparatus is controlled by the current passing between two electrodes through a gas filled chamber in communication with the apparatus. The Figure shows an arrangement suitable for supplying carbon dioxide to a lamp containing that gas, which may be mixed with helium ; lamps containing carbon monoxide are also mentioned. With the body 1 of the lamp communicates a chamber 24 containing cadmium carbonate and a chamber formed by two concentric cylindrical walls 20, 21 on the outer sides of which are electrodes 25, 25a. These electrodes are connected through a condenser 57 and the secondary 28 of a transformer 29. To the primary 40 of the transformer are connected the cathode 56 and anode 50 of a valve 51, the grid 52 of which is connected to the circuit through the electrodes 25, 25a. As long as the pressure in the lamp 1 is normal the current between the electrodes 25, 25a, raises the grid 52 to a potential which inhibits discharge through the valve 51, but if the pressure falls too low the resistance between the electrodes increases and the potential of the grid -52 falls until current passes, heating the cadmium carbonate by means of a heater 32 and causing it to give off gas until the pressure is restored. Several arrangements of the electrodes 25, 25a both inside and outside the discharge space, are described.

Substantially tubular housings 11 (see also Fig. 2, not shown) are applied to electrical connectors such as wire terminals (1) (Fig. 1, not shown) by dispensing the housings into bed member 20 wherein a housing is held against axial movement by tongue 22, supporting the terminal between arms 15 and a spring-biased arm 17 (see also Fig. 4, not shown) with its base against shoulders 16 so that it can only move axially to the right, moving bed member 20 towards the supported terminal, as shown by piston 24 so that when surface 20a pushes surface 17a of arm 17 against the bias, the terminal engages in the housing and is retained therein on retraction of member 20 by a stop (5) (Fig. 2, not shown). In a modification (Fig. 6), insertion of terminal 6 into feed station 62 on block 56 actuates a microswitch causing piston 98 to move to the left and piston 36 to move to .the right. Feed fingers 48 secured by means of block 44 to piston 36 bring terminal 6 into engagement with housing 11 supported in a shoe 97 secured to piston 98. A micro-switch actuated by piston 36 reverses the movement of the piston and the housing plus terminal is ejected from shoe 97 by contact with the edge of next housing 11a. The housing has an internal rib (13), (Fig. 2, not shown), for stabilizing the terminal therein.

Title: Method of making reproductions of mushrooms by moulding
IPC: A41G1/00
Filed: 1936-10-28
Abstract: In making reproductions of mushrooms wherein the mushroom is enclosed in refractory material, calcined, and the ash removed, and the mould so obtained is used for making the reproduction, the refractory material is applied in two layers, the first being finely-grained. The layers may be formed of a composition of one-third plaster and two-thirds silica or quartz sand together with water.  The mould is maintained at a temperature equal to or greater than the melting point of the material to form the pattern or reproduction which is cast or pressed into the mould.  The refractory cover or mould may be placed in a metal casing.  A vent is left for the escape of steam or volatile products from the mushroom.  The material for forming the pattern may be metal such as lead, synthetic resin, or gelatine.  It may be poured while molten into the mould and subjected to centrifugal action.  The pattern may be coloured and used as a reproduction or it may be used for making reproductions in other ways in gelatine, synthetic resin, or ebonite.

Title: Improvements in and relating to electronic impulse counters
Inventor: BRADY THOMAS WILLIAM
IPC: H03K29/00
Filed: 1951-12-17
Abstract: 704,816. Electronic counting-apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 12, 1952 [Dec. 17, 1951], No. 29484/51. Class 106 (1) In an electric impulse counter having one or more stages each including a multi-cathode counter tube in which a discharge is stepped from one cathode in succession to adjacent cathodes in response to a succession of impulses applied to transfer electrodes, the cathodes in the or each stage are connected to a selector switch which is pre-set to a predetermined member whereby the counter is restored to zero after a predetermined count. As shown, the first counter stage comprises a decimal tube T, having ten cathodes 1 ... 9, 0 and ten pairs of transfer or guide electrodes 12, 13 to which negative impulses are applied in succession in response to a positive input pulse at 14 applied to a " flip-flop " (one-stable-state) circuit V1, V2 and network 20 arranged as described in Specification 691,623, [Group XL (c)]. The cathode 0 is connected through valve V3 (corresponding to V), to the next higher stage (not shown) for tens carry. The cathodes of T1 (except 0) are connected to correspondingly numbered contacts of selector switch 16, similar switches being provided for the higher stages. When the discharges in all the tubes reach the pre-selected cathodes (6 for T1), positive pulses are applied simultaneously from the switches through a resistancerectifier coincidence circuit to line 25, and the resultant signal triggers a flip-flop 19 comprising valves V4, V5, thus producing a wide negative pulse at the anode of V4 which is applied via line 22 to the cathode 9 in each tube to bring the discharge to this cathode. Alternatively all the cathodes other than 9 may be driven positive by the anode output of V5. The pulse from V4 is also differentiated by a circuit including condenser 23 so as to produce a delayed positivegoing pulse which is applied to the counter input thus stepping the counter from 99 to zero. The flip-ftop 19 may be used also to set the counter to zero initially.

Abstract: 627,056. Fluid-pressure gauging-apparatus. RUPLEY, F. L. Oct. 3, 1946, No. 29532. [Class 106 (ii)] In fluid-pressure gauging-apparatus a stabilizing chamber communicates with the source of fluid and also with the gauge head which has an orifice with a variable effective outlet area, this chamber having associated therewith a discharge valve adapted in response to a predetermined pressure in the chamber to discharge fluid therefrom into a damping chamber, the latter communicating with a fluid flow responsive instrument. As shown, a housing 47 forming a fluid-tight reservoir has an inner structure in which two restricting devices 49 are arranged. The first device is supplied with fluid, such as air, under controlled pressure through a conduit 48, and communicates by a passage 53 with the second device which is connected by passages 57, 58, 59, 62 with a feeler gauge head 66. Also communicating with the passage 57 is one end of a Bourdon tube 78 acting as a stabilizing chamber, the free end of which has an exhaust aperture controlled by a valve 83 pivotally carried by a block 85. The block 85 is urged by a spring into engagement with an adjusting- screw 88 by which the exhaust of fluid from the tube 78 is regulated. The fluid is exhausted into a damping chamber formed by the housing 47 and passes through a pipe 95 to the bore 96 in a fluid-flow pressure gauge 93 of the type comprising a tapered tube 101 in which is a light bobbin 104, the fluid passing to atmosphere through the upper open end of the tube. The restricting-devices 49 each include thimbleshaped members 50, each with an orifice 51. The fluid on passing through these devices is alternately throttled and expanded, resulting in the elimination of moisture and dirt ; the fluid temperature is also to some extent controlled. The gauge head 66 is secured to the housing 47 by a screw connection, and comprises a discharge port 68 in a member 69, Fig. 6, disposed radially of the head, and a feeler button 70 disposed opposite the port 68 and carried by a spring 71 secured to the head 66. For internal gauging, the head 66 may be cut away at 109 to provide a three-point contact. In a modification a single restricting orifice may be incorporated at the junction of the passages 58, 59. In operation, the discharge of fluid through the port 68 in the head 66 is controlled by a work-piece and this variation affects the pressure in the passage 57. The pressure in the latter controls the bending of the Bourdon tube 78 and the rate of exhaust therefrom to the pressure gauge 93. To avoid the constant use of master gauges for checking purposes, the port 68 is closed and the fluid pressure adjusted so that the bobbin 104 registers at a set point in the tube 101 corresponding to a predetermined work-piece dimension. In a further modification, the stabilizing chamber communicates separately with a discharge chamber having a discharge opening which communicates with a damping chamber, and with a cylinder in which is a piston secured to a valve controlling the discharge in the discharge chamber.

A method for making an oval cast iron pipe circular in cross-section over at least a portion of its length is characterized in that whilst the pipe is within the temperature range 1000 to 1400 F. a transverse force is applied to a region of the pipe as the pipe is rotated in support means said force being sufficient to deflect the pipe in different regions of its surface in succession until the pipe cross-section conforms to a circular shape. The pipe is supported in rollers 2 one or both of which are driven. The transverse force is appled by a roller 3 actuated by an hydraulic cylinder 6 a stop 7 limiting the movement of the pivoted roller arm 4. The rollers 2, 3 extend over the whole length of the pipe and may comprise a single roller or a series of rollers arranged side by side. The single roller 3 may be replaced by two or more rollers arranged side by side and pressing upon circumferentially spaced portions of the pipe. In another embodiment (Fig. 2) the deflecting force is applied to the inner surface of the pipe by a cantilever roller mounted on a pivoted arm 14.

IPC: C13K13/00
Filed: 1956-09-28
Abstract: 1:4-glucosaccharolactone is extracted from an admixture thereof with 3:6-gluco-saccharolactone by contacting the admixture of said lactones with an aliphatic alcohol, preferably anhydrous, having 2 to 5 carbon atoms in the molecule, at normal or slightly elevated temperature, separating the alcohol solution from the residual solids and recovering the said 1:4 lactone from the solution by crystallisation, preferably by evaporating the alcoholic solution, after dilution with water, under reduced pressure.  The solution is preferably seeded with a crystal of the 1:4-lactone.  The residual lactone in solution, after removal of the crystals, can be recovered and dissolved in water with residual 3:6 lactone, the solution being heated whereby equilibration takes place, whereafter the aqueous solution is evaporated to dryness and the mixed lactones are recycled to the process.  The admixture of lactones for starting material may be produced by passing an aqueous solution of a water-soluble glucosaccharate through a cation exchange resin, collecting the effluent and concentrating it and, after standing, seeding the solution with 1:4 lactone.
