As shown in Fig. 2, the track means comprises pairs of parallel rails 25, 26 and 27, 28 carried by rods 19, (20) which are movable to vary the spacing of the rails. When the mould is closed (Fig. 3, not shown), the rails 25-28 are received in recesses 36 in one mould part 7. Movement of the rails 25-28 and rods 19, (20) is effected by cam grooves 33, 34 in plates 35, the cam grooves being engaged by studs 29, 30 connected to the rods 19, (20). The ejector plate 12 is operated by rods 13 which engage bosses 14 when the mould is opened. A blower 52 operated when the mould is opened assists downward movement of moulded articles towards a slide 53 or conveyer. Fig. 8 shows a modification in which the rails 25-28 are carried by rings 41 which are rotatably mounted on the stripper plate coaxially around mould cores 10. The rails 25-28 are pivotally connected to the rings 42 by means of pivot pins 42 which also connect the inner rails 26, 27 to arms 43 operated by a piston cylinder unit 45, 46. On displacement of the piston 46 from the Fig. 8 position the rings 41 rotate in the direction of the arrows 47 and move the rails into operation position. In a modification the rails are mounted on a linkage operated by a solenoid. (For Figures see next page.)
Patent GB-905735-A (GB)
Title: A process for reducing the swellability of foils, filaments or fibres of regenerated cellulose
IPC: D01F11/02
Filed: 1961-03-29
Abstract: A reduction in the swellability of dry foils, filaments and fibres of regenerated cellulose may be effected by treatment with hot water at 60 DEG C.-100 DEG C. for at least 15 secs., after which the material is dried.  The preferred temperature range, requiring treatment for 15-60 secs., is 80 DEG C.-100 DEG C.  Although it is essential to dry the material before and after the hot water treatment, the swellability (or water-absorption capacity) of the product is determined by the temperature of the hot water used for the treatment.  Variations in duration of the treatment, and in drying temperatures have no significant effect on the properties of the product.  The invention is illustrated by experiments on foil made by the cuprammonium process.  Further experiments on regenerated cellulose film and yarn illustrate improvements in bursting pressure, strength value and elongation value achieved by the process.

Title: Improvements in and relating to carbon bleaching or filtering material and method of making the same
IPC: C01B31/08
Filed: 1921-04-21
Abstract: 167,740. Brown, H. E. Aug. 12, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Carbon for use as bleaching or filtering material, in granular form and capable of being pressed into a compact granular mass, is prepared in such manner that each granule consists of a dense hard carbon framework carrying a substantial amount of soft spongy carbon. The. result is stated to be obtained by briquetting a mixture of relatively soft carbon and hydrocarbon and then crushing or grinding the briquettes. In an example six parts of byeproduct coke oven pitch, and one part of byeproduct coke oven light oil are mixed with water, pumped through a filter press and dried until it contains only from ten to fifteen per cent of moisture. This material is briquetted, and the briquettes are broken up into granules and retorted at a temperature sufficiently high to crack and drive off the bulk of the volatile constituents. The mass is then broken up and sieved.

An endless conveyer has a conveying surface 1 provided by a pair of series of plates 2, 2 each of which is pivoted at 5 to a roller chain 4. The plates 2, 2 of each series have a lap joint 3, to provide continuity of the conveying surface in the operative run. As shown in full lines the plates 2, 2 are mutually inclined in a trough-like manner, so as to be able to convey material such as coal, the gap between the plates 2, 2 being closed by a spine 11. The roller chain 4 runs on a platform 15 which may be raised by hydraulic means (not shown). When the platform 15 is raised the two series of plates 2, 2 are mutually inclined in an outwardly downward direction so that side discharge of the conveyed material can take place as shown in dotted lines. Discharge may be obtained from one side only by having only one series of pivoted plates 2, the other series being fixed. Alternatively or additionally tracks 14 may be vertically operable either together or independently. All the plates 2 may be pivoted about a common central longitudinal axis, e.g. in a hinge-like manner, in which case a spine 11 is not required. In a further arrangement a single series of pivoted plates 2 may co-operate in the operative run with and travel relative to a fixed plate or like surface mutually inclined to the single series of plates 2 in the conveying condition (not shown).

Abstract: 423,700. Sheafing-machines. RAUSCH, M., 2, Grabenstrasse, Striegau, Silesia, Germany. April 18, 1934, No. 11689. Convention date, May 2, 1933. [Class 6 (iii)] A sheaf-carrier for a reaping and binding machine comprises a box-like receptacle 4 supported by two main wheels 1, 2, and by a front supporting wheel 3, the wheel 1 being adapted to be coupled intermittently to a sprocket wheel 11 driving an endless conveyer grid passing along the bottom of the receptacle 4 through a one-revolution clutch actuated by the attendant. The conveyer grid is inclined downwards in the longitudinal direction from the front to the rear and transversely from the side adjacent to the binder to the side remote therefrom, loss of grain due to sheaves rubbing against each other being thereby minimized. The transverse bars 9 of the grid are also higher near the binder side. The bars 9 first move over a metal plate 18 when discharging a load of sheaves and then over a grate composed of longitudinally arranged bars 19. Separated grain or weed seeds fall between the grate bars and are brushed by the returning bars 9 along the box bottom and over a ramp 20 into a collecting chamber 22 closed by a hinged lid 24. Leaves and broken stalks escape at the rear end of the conveyer run through an aperture 36. The rear end of the receptacle 4 is provided with a wall 26 which is held in the upright position while the receptacle is being loaded with sheaves, but is automatically lowered to the dotted line position 26<1> when the conveyer grid is set in motion, thus permitting the sheaves to be discharged : after the wall 26 has been withdrawn from below the discharged sheaves it is automatically raised to the receiving position again.

[Class 20(iv)] A compound reinforcement for concrete structures comprising a preformed unit having a hole extending between opposite sides of the unit, at least one tensioned wire or cable threaded through the hole and grouting which has set after being poured into the hole and around the wire or cable, said grouting maintaining the wire or cable in tension and applying the pull of the wire or cable to the unit to maintain it in compression. In one form the reinforcement is made by mounting a series of high quality concrete flanged tubes 1 in coaxial alignment and threading steel wires 4, of high tensile strength, through them, the wires being positioned by drilled washers 5 so that their gravity axis and that of the tubes coincide. The ends of the wires are carried through wood blocks 7 and, at one end of the reinforcement, are secured in an anchorage block 10 by a wedge 12 whilst at the other they pass first through a collar 9 and are then secured in a similar block. The wires are tensioned by a jack which forces the collar 9 and the adjacent block 10 apart, a distance piece being inserted between them when the required tension has been obtained. The jack is then removed. Grout is now poured into the tubes through the holes 20 and after it has set sufficiently, the anchorages 10 are removed by sawing through the wood blocks 7. The reinforcement is used in the same way as mild steel reinforcement, the outside of the tubes being roughened tc give high bonding with the in situ concrete of the structure.
