Title: Mould clamping mechanisms for injection moulding machines
IPC: B29C45/67
Filed: 1971-04-19
Abstract: 1318009 Injection mould closing devices K AOKI 19 April 1971 [22 April 1970] 26917/71 Heading B5A An injection mould is closed by means of a high speed low pressure piston 5 and cylinder 2, fluid being displaced by the piston 5 through an opening 7 into a cylinder 1 containing a clamping ram 4, and high pressure clamping is effected by moving a piston 6 so as to close the opening 7 and admitting fluid to the cylinder 1 through a passage 10 in the piston 6. In operating a valve A is changed to the position seen in Fig. 2 (not shown) so that pressure is supplied from P to a chamber 13 to move piston 5 to the right. Fluid is thus transferred from a chamber 8 to a chamber 9 and ram 4 moved rapidly to the right. When the mould is lightly closed a valve B is changed over thereby opening a check valve 16 supplying pressure to a chamber 11. Piston 6 is thus moved to the right to close the opening 7. Pressure in chamber 11 then increases, and opens a check valve 17, and pressure is transmitted through passage 10 to ram 4 to tightly clamp the mould. In Figs. 4 to 7 (not shown) the clamping mechanism is simplified by eliminating check valves 15, 16. In a further modification, Fig. 8 (not shown), the piston 5 is moved by a pair of plungers (30).

Abstract: 1,224,648. Internal shoe drum brakes. ERNEST A. WEBB Ltd. 6 Aug., 1969 [7 June, 1968], No. 27183/68. Heading F2E. An internal shoe drum brake especially for an industrial tractor has a diametrically-split backing plate, each half of the plate carrying upstanding flanges which can be bolted together in pairs to secure the two halves together; the thus-assembled backing plate has a central hole of smaller diameter than that of the coupling flange on the half shaft of the tractor; the brake also comprises a ring, split diametrically, and having on each half an attachment plate adapted to be bolted to a square portion of the axle arm by bolts external to the axle arm, the ring and the backing plate being bolted together in use in a position such that the divisions in the ring and in the backing plate extend in different planes. The splitting of the backing plate obviates the need for applying it endwise over the coupling flange (which in this case is larger than the plate hole). To install the brake shown, the tractor wheel 15, Fig. 13, is removed. The upper half of the split ring 25, with the upper half of the backing plate 17 bolted to it, is disposed so that its attachment plate 26 lies on top of the (squaresection) inner portion 10 of the axle arm, Fig. 3. Similarly, the lower half of split ring 25, with the lower half of backing plate 17 bolted to it, is disposed so that its attachment plate 26 is underneath portion 10 of the axle arm. Securing bolts 28 are then applied. The attachment flanges 23 on the backing plate halves are bolted together, and a brake adjuster is fitted between the brake shoes (one shoe being shown at 18, Fig. 3). Then a brake drum 16 is fitted over wheel studs 14 protruding from a coupling flange 13 carried on the half shaft located in the hollow axle arm 10, 11, and the wheel 15 is replaced. The upper half of backing plate 17 carries the brake shoes, pivots and return springs 19, while the lower half carries spindle 24, return spring 22 and cam 20. The lower attachment plate 26 carries a lug 33 in which is journalled the spindle 34 to which is attached the brake arm 21. After a brake has been fitted to each of the two driving wheels a cranked and braced cross-bar 30 is connected to the two brake arms 21, a bracket (32), (Figs. 1 and 2, not shown) is attached to the centre of the crossbar 30 and a rod (31) pivoted to the end of hand brake lever (29) is attached by an adjustable threaded connection to the bracket (32).

Title: A vehicle for railway and road service
IPC: B60F1/04
Filed: 1935-10-03
Abstract: 463,951. Rail - and road vehicles. CAPO, E. Oct. 3, 1935, No. 27372. Convention date, Oct. 3, 1934. [Class 108 (ii)] In a convertible rail-and-road vehicle of the kind in which the wheels of one character are mounted on spindles capable of being displaced eccentrically by an angular or planetary movement, the movement of the spindles 3, e.g. of the road wheels 10, Fig. 4, is effected by the rotation of the wheels 10 themselves acting through pinions 6 which engage internal teeth 8 arranged on a relatively fixed member such as the transverse axle casing 1. In the arrangement shown, the vehicle has two pairs of rail wheels 100 and three pairs of road wheels 10, of which two pairs at the ends of the vehicle are adapted to swivel for steering purposes, while the central pair are non- swivelling but spring-supported. To provide for the necessary freedom of movement of the extreme road wheels, the casings 1 are pivoted about horizontal pins 27 in yokes 29 which in turn are associated with drums 33 and are rotatable relatively to a support 30. A cable 32 passing around the front and rear drums ensures symmetry of movement. For the purpose of raising and lowering the wheels 10, one element 4 of a clutch is arranged on the spindle 3 and coacts with a second element 5 which is associated with the pinion 6. Springs 15 acting through rods 11 and fork members 7 tend to uncouple the elements 4, 5, but normally such uncoupling is prevented by the cooperation of a cam 16 on an internally toothed drum 9 and a roller 17 on the fork 7. At two extreme positions, corresponding with the fully raised or fully lowered condition of the wheels 10, the cam 16 permits the springs 15 to separate the elements 4, 5 and to withdraw the nave of the piniori 6 into a locked position within one or other of opposite slots 9<1>, 9<11>, Fig. 7, of the drum 9. In effecting a transfer from rail to road use or vice versa, i.e. by a lowering or raising of the wheels 10, the rails 19 are arranged to slope gradually into a slot 18,and the necessary rotation of the wheels 10 is derived from their forward movement in contact with the ground. Prior to this, the pinions 6 will have been disengaged from the slots 9<1>, 9<11> by movement of the rods 11 through the medium of a cam 13 operated by a key 14. A brake disc carrying brake shoes is adapted for an eccentric but non-pivotal movement corresponding with the eccentric movement of the road wheels.

Abstract: 378,249. Protective pads. YATES, E. D., 93, Stockport Road, Cheadle Heath, Stockport. Oct. 3, 1931, No. 27503. [Class 141.] A protective pad for use in playing games and for other purposes, is provided with one or more attachment members (for example, springs or cards) connected, or adapted to be connected, at two or more points to the same edge of the pad and connected, or adapted to be connected, to itself or to one another at one or more points between the points of conne ction to the same edge of the pad. As shown in Fig. 2, applied to a cricket pad, a coil spring 6 sheathed in rubber or leather is connected to one edge of the pad by tabs 1, 9, 8 and carries by means of slidable hoops 11, 12, a similar spring 13 terminating in eyes 14, 15 and slidable in a central loop 20 carrying an eye 21. In attaching the pad, the eyes 14, 15, 21 are engaged with hooks 19 carried by tabs 16, 17, 18 on the other edge, of the pad, and adjustment is made by sliding the loops 11, 12 along the springs. In modifications, additional adjustment is afforded by replacing the tab 16 and eye 14 by a strap and buckle fastening, or by providing a short spring extension between the tab 16 and eye 14. In a further modification, the two springs 7, 13 are continuous at the upper ends so as to form a single spring. In a further modification, Fig. 7, a cord is employed instead of a spring and the fastenings are tightened up by pulling a portion of the cord through an additional loop 36. In a modification, Fig. 8, the springs 42, 43 are attached to the sides of the pad and are connected by buckles 55. Instead of buckles 55, a sliding fastener of the kind known as a zip fastener may be used. In a further modification, Fig. 11, the two springs 98, 103 after being hooked to tabs 93 .. 96 are tightened up by a strap and buckle 107. A modification where three springs are used is shown in Fig. 12. The upper spring 110 may be in two portions to provide a slidable adjustment for tightening the pad. The pad may be modified for use as a shin guard, an arm pad or a body pad.

Title: Improvements in the treatment of materials with binders and in briquetting said material
IPC: C10L5/14
Filed: 1926-11-03
Abstract: 286,336. Lessing, R. Nov. 3, 1926. Materials and compositions for making coke.- In briquetting anthracite, bituminous, or other coal prior to coking, the material is coated with coal tar or other liquid containing pitch-like and oily fractions. An oil solvent containing little or no aromatic constituents, such as distillates from petroleum, shale or primary coal tar, is then used to extract the oil portion and precipitate the pitch as a homogeneous coating on the coal &c. particles. The oil solution may be removed by draining, filtering, or centrifuging, assisted by pressure or vacuum and may be distilled to recover the solvent and obtain tar oils which may be distilled for the preparation of the tar fractions, the bituminous residue obtained being added to the briquetting mixture. A current of superheated steam may be passed through the mass before briquetting to recover remaining traces of the solvent. Extraction of the tar oil is facilitated by the addition of sulphuric acid, an acid solution of iron sulphate or chloride, or the spent liquor from pickling steel. In an example, 100 parts of washed and dried anthracite duff are mixed with 20 parts of dehydrated coal tar (containing 50 per cent of pitch) and 1 part of sulphuric acid which may be diluted with an equal volume of water is added. Petroleum spirit of boiling point 100-120‹ C. is then caused to percolate through the mixture and clean spirit is superimposed and allowed to descend as a continuous unbroken body to enable the solution to be withdrawn with the least possible dilution. That part of the solvent with an oil concentration of less than ten per cent may be used with a fresh mixture prior to the final extraction with neat solvent; the other part containing up to 30 per oent of oil is distilled. Petroleum fractions free from aromatic constituents and boiling at 60-80‹ C. may be employed as solvent. Catalysts may be added during the mixing of the materials so as to be present mainly on the coal particles or on the pitch film. Specification 130,362 is referred to.
