Title: Improved method of and means for making bricks and such like
IPC: B28B5/04
Filed: 1929-12-14
Abstract: 341,670. Making bricks by combined moulding and re-pressing. PLATT BROS. & CO., Ltd., Hartford Works, and JENKINSON, T., 80, Wrigley Street, both in Oldham. Dec. 14, 1929, No. 38317. [Class 87 (ii).] In a combined moulding and re-pressing machine each brick is given a dead-weight blow prior to each of the double-pressing operations. In the illustrated form for making two bricks at each operation, two charges of clay are delivered simultaneously from the hopper 11 to the reciprocating slide 5 and are thus delivered to the first pair of parallel moulds 2. On the succeeding stroke the pressed bricks are delivered to the moulds 3 for re-pressing, and on the third stroke they are ejected past the anti-friction roller 4 for delivery. The slide is operated by cams 18, 19, Fig. 7, on the shaft 20, which co-operate with guided members 13 linked by a lever 28 to the central arm 9 of the slide and are set so that the slide is stationary for about three-quarters of the revolution of the cam shaft and performs the advancing and retracting movements in the remaining quarter revolution. During the pressing operations the material is subjected first to the dead-weight pressure of the upper rams by raising the ram-carrying frame 47 through the medium of the cam 49 and then allowing it to drop suddenly. A further pressing is then accomplished through the medium of the cams 40, 42 acting on the upper rams 33, 34 in conjunction with similarly-actuated lower rams actuated by the cams 55, 57. Separate cams 62 act on the lower rams at the completion of the pressing operation to raise the moulded brick for transition to the next stage. A strickle adjustable by hand-actuated bevel-gear trims excess material from the slide on the forward stroke.

Abstract: 1308993 Making valve cores; rolling A E BISHOP 18 Feb 1970 [26 Feb 1969] 38691/72 Divided out of 1308992 Headings B3A and B3M A valve is made by the steps of turning a valve core having an arcuate external surface with a longitudinally extending slot and impressing a contour design of irregular configuration on at least one side of the slot by introducing a tool member bearing the contour design generally radially into the core. As shown in Fig. 1, rolling apparatus comprises a collet 20 which, carried by a sleeve 21 and reacting against a chuck 22, grasps a valve core 10. Six equally spaced rolling dies 25 are each carried in a block 27 pivotal about a fulcrum 28 secured to the carrying block 29. Clockwise pivotal motion is given to blocks 27 by means of a piston 30 carrying cam projections 31 which co-operate with pivot pins 27a. Piston 30 simultaneously carries chuck 22 and workpice 10 with it. Return movement of the die blocks is accomplished by retractor 35 which is moved to the right by means of sleeve 34 carrying cam 38 which pivots retractor 39. The rolling dies have an arcuate surface 26 shaped to modify the valve core groove to its final desired form. Final grinding removes upset material from the periphery of the valve core. As an alternative to the rolling technique the longitudinally extending groove may be modified to the desired contour by an electrical spark gap apparatus or an end mill of extremely small radius.

Abstract: 1,125,956. Cellulosic pulps; paper. FIDES TREUHAND-VEREINIGUNG. 13 Sept., 1965 [14 Sept.. 1964], No. 39005/65. Headings D2B and D2W. Paper having a low dielectric loss is obtained by treating an aqueous dispersion of finelydivided cellulose comprising at least 80% of alpha-cellulose with an aqueous solution of a water-soluble salt, oxide or hydroxide of lead, mercury, nickel, beryllium, aluminium, germanium, cadmium, tin, zinc or zirconium, washing the treated cellulose with water and converting the washed cellulose into paper the washed cellulose comprising substantially the sole cellulose constituent of the paper. The aqueous suspension may be placed in an electrolytic tank having an anode, which may be a wall of the tank of a separate anode, of one of the metals listed, and the water-soluble salt, oxide or hydroxide formed therein. The cathode may then be in a compartment separated from the reaction compartment by a cation-exchange diaphragm. The water in which the salt is dissolved, and that used to wash the treated pulp may be deionized. The pulp to be treated may be first washed with an acid to remove ashforming constituents, and in this case the watersoluble salt, oxide or hydroxide may serve to neutralize excess acid.

Filed: 1959-11-17
Abstract: 918,465. Loading material into vehicles. WALKERS & COUNTY CARS Ltd. Feb. 17, 1961 [Nov. 17, 1959; April 8, 1960 (3)], Nos. 39009/59, 12529/60, 12593/60 and 12636/60. Class 78 (4). Refuse to be charged into a vehicle is first swept off a charging floor 13 (Fig. 1) into a cylinder 11 containing a piston by which the refuse is first compressed and then pushed through an end gate 25 into the vehicle. In the arangement of Fig. 1, vehicles are guided up ramps 26 into engagement with cylinders 11 by roller guides 27, and are then secured by latches. A wall 22 around the floor 13 confines material so that it can only discharge through a hole 24. The charging aperture in the cylinder is closed by a hollow plug 47 (Fig. 4) pivoted at 58 and moved through a linkage by a ram 54. The plug 47 may, however, be replaced by a hinged shutter, which may confine the material when it is open so that the wall 20 (Fig. 1) can be omitted, or by a gate sliding circumferentially. The open gate may also serve as a bridge between the charging floor and the cylinder. With the latter arrangement the cylinder 11 extends partly above the floor 13. In still a further arrangement the charging aperture may be closed by a skirt fixed to the piston, or moved axially relatively to it by a ram. The compressing cylinder 11 may be inclined, as shown in Fig. 2, and may be carried by trunnions 34 so that a weighing cell 39 can indicate its weight at 43. A spring 7 may bias the cylinder about its trunnions. The compressing piston may include two portions 62, refuse trapped between these portions escaping through an aperture 64. Alternatively the piston may be of dumb-bell shape. The cylinder 11 may terminate in a portion 100 (Fig. 15) slid axially by a ram 103, to ensure sealing engagement with the vehicle, and the end gate 112, guided by rollers 94, may be moved by rams 96 mounted in either of the two alternative ways illustrated in Fig. 15. A cat walk 28 (Fig. 1) is provided above the compressing cylinders, and vehicles to be discharged can reach the floor 15 by way of ramps 15, 18. Specification 910,158 is referred to.

In a spring retraction reel device for vehicle and workmen's safety belts a pawl 17 pivotally mounted on an end plate of the reel casing is biased by a spring 22 to the position of Fig. 2 in which the rounded limb 21 slides over the teeth of a ratchet wheel 18 mounted on the reel spindle (6), Figs. 4 and 5 (not shown), during gentle withdrawal of the belt from the reel. At a sharp pull on the belt the limb 21 is knocked outwardly against the action of the spring 22 causing a pawl tooth 23 to engage a tooth of the ratchet wheel and lock the reel. The wheel 18 is mounted on a threaded portion (19) of the spindle, Fig. 4 (not shown), and located between it and a belt retaining plate 9 is a disc (20) of malleable metal or plastics. Immediately the pawl tooth 23 engages a tooth of the ratchet wheel 18 the latter is screwed along the spindle and compressively deforms the disc with consequent absorption of the energy of e.g. the collision which caused the rapid pull on the belt. The limb 21 may be associated with an adjusting screw to vary the reaction time of the pawl and ratchet locking mechanism.
