Patent GB-1370667-A (GB)
Title: Injection moulding apparatus
IPC: B29C45/06
Filed: 1971-10-01
Abstract: 1370667 Injection mould control BRITISH BATA SHOE CO Ltd 1 Oct 1971 [17 May 1971] 45889/71 Heading B5A The amount of material injected into each mould 3 on a turntable 2 is controlled by a switch 101 which is actuated to stop the injection by a rod 50 of adjustable length attached to the movable bottom of the mould being filled when the bottom has been depressed by a predetermined amount by the injected material; and variation in the amount of material in each injection, caused by tilting of the turn table, is reduced by a cam means acting between the rod and the switch to adjust the length of the rod immediately before injection to set the distance from the switch to the mould to the same value each time, In Fig. 1, a machine for moulding soles into lasted uppers comprises a base 1 on which is mounted a central column 8 carrying four last supports each having two lasts (not shown) attached to faces 12. The last supports are rotatable and slidable on column 8 so that they can be loaded in an upper position, then rotated to a lower position and lowered onto a mould bottom 3. The base 1 also carries turntable 2 and two injection moulding machines 4 feeding different coloured thermoplastics or uncured rubber into each mould. The bottom of each mould is supported on the turntable 2 by a double-acting pneumatic ram 22 (Fig. 2, not shown) which resists the depression of the mould bottom with an adjustable pressure. The switch 101, Figs. 3 and 4, for stopping the injection and two connected cam tracks 73, 74 are fixed to a carriage 85 vertically reciprocable against springs 96 within bracket 86 fixed to base 1. The upper part 52 of rod 50 is fixed to the mould bottom and to a sleeve 53. The lower part 54 of rod 50 carries rollers 70 on axle 71 and is slidable within sleeve 53 against the braking effect of plugs 61 biased against the sleeve by springs 59, within the range limited by pin 62 engaging slot 63. A cam following rod 65 carrying roller 68 is rigidly connected to the turntable by a bracket 58 connected to the cylinder of ram 22.  In use as the turntable rotates a mould into position for injection axle 70 engages upper cam track 74 and fully extends rod 50. Roller 68 then engages cam track 73 and forces it down from the dotted to the full line position of Fig. 3. The rollers 70 engage the depressed guide track 73 forcing rod 50 to contract to the correct length. The part of the guide track 73 engaged by rollers 70 is discontinued at 80 and thereafter rod 50 is free to descend with the mould bottom until it contacts switch 101. Tilting of the table after the length of rod 50 has been set will be transmitted through cam follower 65 to carriage 85 thus causing a similar compensating movement of switch 101.

In an embodiment (Fig. 1) the plug 12 and socket 14 have mounting holes 18, 62 respectively and may be moulded of phenolic resin. Each pin 30 has a support portion 32 with ribs 34, closely engaging the walls of hole 36 and secured thereto by epoxy resin and is connected to one of leads 37; a portion 40 allows twisting of the contact 42 on entering opening 92. The rigid sockets 80, each including a support portion 82 and ribs 84, are secured by epoxy resin in the holes 86. Each contact 42 is of a substantially flat form made of a single piece of wire bent in an elongated rectangle and is aligned along an axis which is at an angle, e.g. 10 to 50 degrees to the major transverse axis of throat portion 92. In a modification (Fig. 5, not shown) the plug pin (130) is a blade (142) which is twisted about a rod (140) as it enters opening 92. In an alternative embodiment (Fig. 7, not shown) the contact (242) is twisted along its length, with its lateral edges describing a partial helix, and its free end (243) may be aligned with the surface 22; in this case the contact (242) affords a cam action, and the socket may be formed with a slot opening replacing throat portion 92. The sockets may be provided with lateral shoulders along their respective longitudinal axes to aid assembly and longitudinal striations or knurls may be provided along the support portions on both the pins and sockets for improved rotational rigidity and the support portions may be mounted in the respective base members by press or spline fit.
Patent GB-1059949-A (GB)
Title: Method for concentrating salt water
IPC: C01F11/46
Filed: 1963-11-21
Abstract: The formation of scale on the heating surfaces during the boiling of salt water is prevented by adding about 0.1% of an amphoteric ion exchange material selected from natural or manufactured forms of silicic acid, silica, alumina or an p  alumino-silicate such as bentonite, kaolin or a zeolite.  Instead of separating the sodium ions as Na Cl, they may be separated as a double salt of Na2SO4 and CaSO4 by adding calcium chloride or calcium sulphate to the salt water.  The double salt may be broken down by electrolysis, and the calcium sulphate recycled.  Examples are given relating to the concentration of sea water in glass and iron vessels.

Title: Process for producing substantially ash-free coke from coal
IPC: C10B55/00
Filed: 1964-11-26
Abstract: Crushed coal and/or lignite is coked by the method described in Specification 964,574, but the aromatic solvent used has cut points (at 1 atmos.) of from 315 DEG  C. to 482 DEG  C. (i.e. 600 DEG  F. to 900 DEG  F.).  The preferred solvent includes phenanthrene (b.p. 340 DEG  C.), and its homologues but other polycyclic aromatic solvents derived from catalytic and thermal cracking of petroleum or from coal tar pitch may be used.  The flow diagram of the process is identical with that described in Specification 964,574, and apart from the solvent, the methods are the same except for minor temperature differences at which the coal &c. is mixed with the solvent. Two coking methods are referred to: (a) delayed coking as shown in the Figure, and (b) contact coking in which the feed flows downwardly with a particulate material.
