Title: Wire stripping device
Inventor: LEWIS ROBERT WILLIAM
IPC: H02G1/12
Filed: 1963-11-19
Abstract: 1,060,669. Stripping conductors. STANDARD TELEPHONES & CABLES Ltd. Nov. 13, 1964 [Nov. 19, 1963], No. 45597/63. Heading H2C. A tool for parting portions of insulating covering, e.g. of P.V.C., from a conductor includes jaws 3, 4 of which at least one is movable, to crush and thereby split the insulating material along the length of a portion and members at the ends of the jaws for facilitating the parting of the insulating material at the ends of the portion after the crushing operation. In the tool shown in Fig. 1, after the insulation has been split, blades 11, 12 are moved outwardly, against the action of spring 16, by rods 15 to stretch and remove the insulation. The blades may be operated manually, hydraulically or pneumatically as are the jaws. By using suitable width jaws, a number of insulated conductors can be operated on simultaneously. In one modification (Fig. 3, not shown), more than two jaws are used. In another modification (Fig. 4, not shown), the blades have cutaway portions to fit round a conductor and are moved towards the centre of the conductor instead of along it.

Title: Process for the production of epoxide resins
IPC: C08G59/08
Filed: 1964-11-10
Abstract: Shaped articles of hardened epoxy resins are produced by curing with a curing agent a polyglycidyl ether prepared by (1) reacting a phenol or an etherified phenol containing at least one free phenolic hydroxyl group per molecule and a halogenated paraffin containing at least 2 halogen atoms and 10 to 40 carbon atoms and having a halogen content from 10 to 50% by weight at 120 DEG  to 200 DEG  C. in the presence of zinc or an acid catalys, and (2) reacting the resultant haloalkylation product with an epihalohydrin or dihalohydrin at 80 DEG  to 120 DEG  C. in the presence of a basic catalyst. The halo-paraffins specified are the chlorination or bromination products of Fischer-Tropsch synthesis hydrocarbons or of hydrocarbons extracted from petroleum fractions by the urea process.  Phenols specified are phenol, alkylated phenols, naphthals, dihydroxybenzenes and dihydroxydiphenylalkanes.  The phenol-halo-alkylation products may be partially etherified with bis-halogen compounds, condensed with formaldehyde, or, if they still contain halogen, reacted with mono- or polyphenol, before condensation with the halohydrin. Acid catalysts specified are Al,Cl3, SnCl4, ZnCl2 or acid fuller's earth. The specified basic catalysts are alkali metal hydroxides. If desired, the halohydrin ethers may be first formed by reaction with the epi-ordi-halohydrin in the presence of a quartenary ammonium salt, a thioether or a sulphonium compound, and then converted to the glycidyl ether by reaction with the base.  The haloalkylation products may also be mixed with conventional polyphenols before epoxylation.  The glycidyl ethers may also be mixed with other polyepoxides before curing.  Many conventional curing agents for epoxy resins are specified. The curable compositions may also contain aminoplasts, phenoplasts, bitumen, glass fibres, sand, gravel or asbestos.  Some of the glycidyl ethers are benzine soluble.  Articles specified are moulds, drop-hammer dies, patterns, templates, coatings, sealants, linings for tubes and vessels, laminate and road surfaces.  The glycidyl polyethers of the haloalkylation products are also useful as softeners, plasticizers, adhesion promoters or stabilizers for polyvinyl chloride and copolymers of vinyl chloride and vinylidene chloride.

Filed: 1968-10-04
Abstract: 1,206,060. Power steering mechanism. HELICOIL CORP. CONTROLS DIVISION. 4 Oct., 1968 [12 Oct., 1967], No. 47684/68. Heading B7H. [Also in Divisions F2 and G3] A servo-valve for the power steering mechanism of a vehicle comprises a spool valve 14, and a ceramic bimorf 42. The pressure on the spool 14 is controlled on the one side by the spring 28 and on the other by the size of the orifice 26. An electrical input impressed on the piezo-electric bimorf 42 causes a displacement of part 44 and hence a displacement of the spool 14. The fluid input 36 is then connected to either of the output ports 38 or 40. The displacement of the spool 14 can be increased by the addition of a bellows-type hydraulic transformer (66), Fig. 2 (not shown), in which case the spool may respond via a rod (55) or a change in orifice size as in the embodiment of Fig. 1.

Title: Injection moulding or die casting machine

Filed: 1971-10-12
Abstract: 1371199 Die casting machines K HEHL 12 Oct 1971 [17 Oct 1970 6 Feb 1971] 47377/71 Heading B3F [Also in Division B5] In the hydraulic drive system of a mould clamping unit for injection moulding plastics or die casting metals comprising fixed and rigid mould carriers 15, 16 moved relatively by hydraulic cylinders 17, 19 fed by a pump system 1, 2, 3 with hydraulic fluid alternatingly in a high pressure range and in a low pressure range, a line 26 leading to the cylinders is connected via a slide valve 9 to a pressure relief valve 25 connected to a reservoir 4, the slide valve being open during the closing stroke so that the pressure relief valve 25 prevents damage to the mould halves if a foreign body is caught between them. As shown the mouldcarrier 15 is attached to cylinders 19 and the movable mould carrier 16 to piston-rods 22. Cylinders 17 are coaxially fixed to cylinders 19, their pistons 21 forming larger diameter extensions of piston-rods 22. To open the mould slide valve 7 is moved to the right so that low pressure fluid is pumped through line 31 to cylinders 17. As the pistons 20 of cylinders 19 are moved to the left fluid is forced from chambers 36 to chambers 29 through line 30 and valve 23. Due to the smaller crosssection of chambers 29 the excess fluid from chambers 36 is discharged through line 26 via valve 14 which is only closed when a mould guard is in place. In one mode of operation valve 8 is positioned as shown and fluid flows from line 26 through valves 7 and 8 to reservoir 4. In a second mode of operation valve 8 is moved to the right and the displaced fluid is directed via line 39 to assist in filling cylinders 17. . To close the mould valves 7 and 8 are moved to the left so that fluid is pumped at low pressure through line 26 into the connected chambers 36 and 29 and discharged from cylinders 17. Due to the difference in the working area of the opposite faces of pistons 20 they are displaced to the right. When the mould is closed the pump pressure increases and valve 23 is operated to close the exit from chambers 36 and to direct the fluid from chambers 29 to reservoir 4. Once the mould is closed the pump 2 can be used to operate the injection process. The pressure relief valve 25, which opens at a pressure below the low pressure range, is connected to line 26 during the last phase of the closing stroke by operation of slide valve 9, thus reducing the pressure in chambers 36 and slowing the stroke. The speed of opening and closing is otherwise controlled by valves 12 and 10 respectively. In the second embodiment (Fig. 2, not shown) the slide valve 9 is omitted and the pressure relief valve (35) is permanently connected by a branch line (34) to line 30. Thus the pressure relief valve is connected to chambers 36 during the opening and closing strokes but is disconnected by valve 23 when higher pressure is required during mould clamping. The low pressure range is set a little below the opening pressure of the pressure relief valve (35). Reference is made to Specification 1,371,198.
