Abstract: 442,157. Conveyers; loading-platforms. ORD, L. C., 19, Adam Street, Adelphi, London. Aug. 3, 1934, No. 22639. [Classes 78 (i), 78 (iv), and 104 (ii)] In a conveyer system particularly for transferring goods from railway waggons w to a fleet of lorries g serving different districts. The conveyer moves as a whole in a closed path and is formed of a numbers of sections a each of which partakes of the general movement of the conveyer but is capable of independent movement so that any section can be moved to any particular lorry and unloaded without delaying the remainder. The independent movement of the sections is derived from a towing " mule " e which is independent of the main conveyer driving means and traverses independent tracks in either direction. The " mule " is coupled to and uncoupled from the appropriate section of conveyer and is driven by an electric motor under the control of an attendant. After passing the lorries, the unloaded sections are returned to the loading end by the general movement of the conveyer. In the form shown two conveyer assemblages are provided, and to facilitate the transfer of the goods from the rail waggons to the sections of the conveyer, an unloading conveyer i is arranged transversely of the distributing conveyers, is movable longitudinally in its bed l, and is provided with a loading plate at one end.

Title: Process for preventing the adherence of cementitious materials to a moulding surface
IPC: B28B7/36
Filed: 1952-09-10
Abstract: Cementitious material is prevented from sticking to a moulding surface by applying a layer of a water-soluble silicate, e.g. waterglass, to the surface, drying the layer, without impairing its solubility, by heating e.g. at 60 DEG C. applying the cementitious material, and then allowing the water in the cementitious material to resoften the layer.  The material and the surface may be immersed in water to facilitate removal of the material.  By p  adjusting the temperatures of the drying of the layer and the setting of the material, the resoftening may be arranged to occur before, during or after setting.  The layer may contain mineral powders, e.g. calcium carbonate, iron or zinc oxide or barium sulphate.  The cementitious material may contain fibrous material. It is stated that it is known to use solutions of water-soluble zinc or copper salts or a mixture of sodium chloride and potassium carbonate.

Patent GB-368193-A (GB)
Title: Improvements in or relating to the preservation of rubber latex
IPC: C08C1/06
Filed: 1931-08-12
Abstract: Latex is preserved by adding a small amount of formaldehyde, allowing to stand, and then adding a small amount of ammonia or its equivalent such as trimethylamine tetra ethyl ammonium compounds &c.  The amount of formaldehyde added should be small, e.g. 0,2 parts, such that it is completely absorbed by the latex, producing a tanning effect on the proteins and giving a non-water absorptive rubber.  Since no combination of formaldehyde and ammonia can take place, no accelerator is produced to interfere with the subsequent treatment of the rubber.  The preserved latex remains mobile, and retains its mechanical stability for long periods.  In an example 100 parts of latex is treated with 0,2 parts of formaldehyde, allowed to stand for twenty-four hours and then 0,5 part ammonia added.

Title: Improvements in fisherman's reels
IPC: A01K89/015
Filed: 1946-08-03
Abstract: 614,837. Fishing-reels. BARNSLEY, H. B. Aug. 3, 1946. No. 23198. [Class 48] The reel handle axis is in line with the spool axis, or parallel thereto, and is parallel to, or substantially so, to the fishing rod. The reel is contained within a casing which is secured by a T-shaped clamp to the rod. The reel G has a bush g which is free on the spindle d<1> as shown in the figure. When a knob N is screwed along the spindle a spring M is compressed and presses a washer K into frictional hold on the spool through a washer K<1> which cannot turn on the spindle. The spool is pressed against friction material j on a washer J. The spool can turn only wi h considerable friction while the handle is held or turned, but can turn freely if the handle is released. Further screwing of the knob N locks the spool on the spindle. The disc J rotates with the spindle when the handle is turned to wind in the line, making a stud j<1> travel around a slanting face b<1> on a head b causing the spool and spindle to be intermittently moved to and fro axially to lay the line evenly on the spool. When casting the line, it is disengaged from the pick-up R and unwinds from the spool without turning it. The fixed cam face b<1> is secured against the casing A by a nut C. A set-screw P prevents the nut N from being screwed off the spindle. The line-pick-up hook R may be screwed into either of two lugs Q.

Title: Improvements in and relating to electric welding machines
IPC: B23K11/06
Filed: 1919-09-22
Abstract: 155,899. British Thomson - Houston Co., Ltd., (General Electric Co.). Sept. 22, 1919. Welding.-In an electric resistance line-welding apparatus, a number of electrodes are arranged in tandem so as to move alcng the seam, and thus effect a longer weld with a given stroke of the electrodes. The movable electrodes are preferably connected in series, the weld. ing circuit being completed through a stationary electrode on the other side of the work so as to maintain a substantially constant impedance. Two series of electrodes 8, 9 mounted in turrets are respectively carried by arms 10, 11 insulated from each other at 20, 21 and connected to each other by a slot 13 and bolt and nut 12. The arm 11 is connected at 18 to one end of the secondary 15 of a transfcrmer 14, Fig. 1, the other end of which is connected at 17 to a shoe 16 in contact with the arm 10. The arms are provided at each side with uprights connected to cross bars 26 and through the uprights pass the shafts of rollers 27, 27 so as to form a carriage. The ends of the roll shafts are received in plungers 31 cushioned by springs in cylinders 32 on the cross-bars, the tension of the springs being adjustable to vary the pressure, of the electrodes on the work. The transformer moves with the carriage and may serve to exert pressure on the work. The rollers run on a pair of arms 35 connected together at 36, and pivoted to the frame at 37. The arms 35 are attached at the other end to levers 48 connected by a rocker arm 39 and lever 41 to a cam 42 which is operated by a handle 43 so as to raise the arms 35 and thereby raise the electrodes from contact with the work after welding or prior to changing the electrodes. This motion is assisted by a counterweight 45 connected by a cable 46 to a lever 44 pivoted to the shaft carrying the arm 39. The electrodes are positively rotated during their traverse by worm and spur gear, the wormwheel being mounted on the same shaft as a spur-wheel which engages spur gears on the roll shafts. The turret is prevented from rotating during operation by a worm-wheel 60 pressing a wcrm 57 against a shoulder 59. On reverse rotation of the carriage, the worm-wheel 60 pushes the worm 57 axially to the left and in so doing is rotated so as to remove the electrodes out of contact with the work as shown in Fig. 3. When the next piece of work is placed in position, the turret is rotated, after raising the arms 35, by a handle 61 so as to place the next electrode into working position. The work is placed on the adjustable stationary electrode 7. Specification 135,244 is referred to.

Abstract: 506,122. Discharge apparatus. PATENTVERWERTUNGS-GES. HERMES. Aug. 8, 1938, No. 23403. Convention date, Aug. 7, 1937. [Class 39 (i)] In a high voltage gas or vapour filled electric discharge device in which there are one or more intermediate electrodes between anode and cathode, a conductive screen 12, maintained approximately at the anode voltage, is arranged between the anode 8 and the wall 1 of the vessel, and a part of an intermediate electrode 3 projects at 15 into the gap between the screen and the anode. The anode arm is of glass or a number of ceramic sections soldered together at their metallized ends. The intermediate electrodes, each comprising stepped concentric tubes 4, 5, 6, 7 are supported by rings between the tube section 1, and are maintained, e.g. by a capacitative potential divider, at such potentials as to give a uniform potential drop along the anode arm and to act as de-ionizing screens. The anode 8 is carried by a lead 9 on a metal plate 10 which closes the end of the anode arm and on which is mounted a graphite block 11 and cylindrical screen 12. The concave anodo may thus be adjusted without altering its distance from the block 11. The plate 10 and anode may be connected by a high resistance 14 or by the insulating block 13 which may have the desired resistance of say 10<4> ohms. A spherical screen 16 is provided. Specification 499,579 is referred to.

Title: Method and machinery for electrifying pile fabrics
IPC: D06C19/00
Filed: 1974-05-24
Abstract: 1421880 Finishing fabrics D FRISHMAN 24 May 1974 23423/74 Heading D1S A continuous length of pile fabric is electrified, i.e. polished, by passing the fabric 11 withthe pile side exposed over a cylinder 10 and electrifying the pile of the fabric by heated electrifying cylinders 12 disposed in planetary arrangement over at least one third of the length of the circumference of the cylinder 10, the cylinders 12 being driven to throw the pile forwards and backwards to. eliminate the possibility of lengthwise streaks on the fabric, the initial cylinders 12 contacted by the fabric 11 having spiral grooves which cross-over and the final cylinders 12 have grooves with no crossovers. In one embodiment, Fig. 1, the fabric 11 is guided about the cylinder 10 by rolls 14, 15 and each cylinder 12 rotates in the direction opposite to that of the adjacent cylinders. However, it may be advantageous to have, for example, the first four cylinders 12 alternating their direction of rotation and the last four rotating in the same direction to form a laiddown finish. The cylinders 12 are heated either internally by electrical units or externally by radiant heaters 21. In the event of a stoppage, the fabric 11 is removed from the cylinders 12 by removal of the cylinder 10 by an electrical and/or pneumatic device 20. Before electrification, the fabric 11 sprayed at 16 with water, an aqueous alcohol solution, a textile softener or a silicone solution. During electrification, the pile of the fabric is raised and lint is removed therefrom by a suction system 17 having heads 18. The initial cylinders 12 are formed with grooves in the form of oppositely wound spirals which cross each other, see 12B, 12C, Fig. 3, the cross-over points on each cylinder falling at different positions than on the other cylinders along the length of the cylinder. The final cylinders 12A, Fig. 3, have spiral grooves which do not cross. In another embodiment, Fig. 2, the number of cylinders 12 is increased and, in the event of a stoppage, the cylinders 12 are moved away from the fabric 11 by electrical and/or pneumatic cylinders 13. Each cylinder 12 is adjustable with respect to its distance from the cylinder 10, e.g. by rotation of threaded couplings 13A. In a modification (not shown), devices to remove the cylinders 12 from the cylinder 10 as in Fig. 2 are incorporated in the embodiment of Fig. 1.
