In modifications, the guide pins 8 may be carried by the support member I the jaws 13, 14 being pivotally mounted on the member 7 or the jaws may be slidably mounted on the member 1 or 7 the movement of each thereof being controlled by two guide pins and two slots; the two members may be provided with co-operating locking cams to resist relative turning of the members.
Patent GB-268268-A (GB)
Title: A new or improved method of and means for moulding or shaping teacups and the like articles provided with handles
IPC: B28B11/02
Filed: 1927-01-14
Abstract: 268,268. Bailey, J., and Furnivals (1913), Ltd. Jan. 14, 1927. Moulding hollow-ware.-For moulding or shaping tea-cups and like articles with integral handles in one casting or moulding operation, a one-piece mould is used having a small detachable handle portion formed in two or more parts. Thus, a roughly-shaped clay handle may be inserted in the recess of the separate mould member B before it is pushed into position in the main mould A. After the body of the article has been produced by jolleying, the article and the member B are removed from the main mould as a unit and the member B afterwards freed from the handle by a lateral movement. In some cases the whole article may be cast at one operation instead of being jollied, but the method of manipulating the mould parts remains unaltered in this case. For making cups with block handles, the handle recess can be in the centre of the member B instead of at one side, in which case the handle is tapered sufficiently in thickness to permit the member B to be detached therefrom. In a furher modification the separate mould member is divided vertically into two parts, each containing half of the handle-forming recess.

Title: Single station glass-to-metal fusion machine
IPC: H01J5/26
Filed: 1960-01-12
Abstract: 937,868. Glass-to-metal seals; tweezers. PACIFIC SEMICONDUCTORS Inc. Jan. 12, 1960 [Jan. 12, 1959], No. 1145/60. Classes 56 and 61. An envelope G, for a semi-conductor device, comprises metal sleeves 11a and 11b sealed into the ends of a glass cylinder 10, and is made by assembling the three parts together, placing one sleeve on to the end of a mandrel, engaging an axially aligned mandrel with the other sleeve, bringing the assembly G into a heating zone by axial movement of the mandrels and, after fusion, separating the mandrels to release the fused assembly. The mandrels are shaped and dimensioned to determine the finished length of the fused assembly. An apparatus, Fig. 3, comprises two mandrels 15 and 16 with ends of reduced diameter to fit into the metal sleeves, the mandrel tips being formed with a pin and a recess respectively for interengagement when the mandrels are brought together. The mandrels are slidable within bearings 42 and are moved by pistons 53, 63 in double-acting air cylinders 50, 62 operated by solenoids controlled by an electric circuit, a suitable type of circuit being described in detail. Spring plates 54 are positioned so that when both mandrels are fully separated and withdrawn into their bearings the assembly G will be stripped off whichever mandrel it may have remained attached to. A H.F. induction heating coil 30 is supported horizontally with its axis aligned with that of the mandrels. In operation the lower mandrel 16 is in the position shown and the unfused assembly G is placed upon it. Closing of the electrical circuit results in the upper piston depressing the upper mandrel 15 until the reduced portion of the mandrel is engaged within the sleeve 11a. The mandrel continues its downward stroke taking the assembly G and the lower mandrel with it against the action of a spring within the lower air cylinder 50, until the assembly G is at the centre of heating coil 30 which is energized to soften the glass 10 around the ends of the metal cylinders 11a, 11b. The pressure of the mandrels, due to the spring, causes the softened glass sleeve to shorten until the ends of the mandrel abut and thus determine the final length of the assembly G. The coil 30 is then de-energized and, when the assembly has had time to cool, the mandrels separate and the assembly G is stripped off. A pair of tweezers (Fig. 8, not shown) for picking up the assembly G and placing it on the lower mandrel has each of the holding ends split into two fingers, these fingers being spaced apart by an amount equal to the length of the glass cylinder 10 so that when the tweezers are used to pick up the assembly G the metal sleeves 11a, 11b will be gripped by the fingers which are curved to a radius matching that of the sleeves. U.S.A. Specification 2,815,474 is referred to.

In a rolling mill according to the parent Specification, each single backing-roll is replaced by a pair of backing-rolls, each of which comprises a plurality of roll sections arranged along an axle with spacing elements therebetween, each of said sections comprising an inner ring fixed to the axle and an outer ring rotatably mounted on said inner ring, the peripheral surfaces of some of said inner rings being concentric and some eccentric to the axle. Each working roll 16 is linked to an annular roller cage 34 by a pivoted lever 36 which carries bearings 98 for the roll 16 and carrier elements 99 to support one of the backing-rolls 25 of a pair. The lever 36 has a tension-spring 109 to ensure continuous abutment between the working and the backing rolls and a counterweight 110 to counter the centrifugal force tending to lift said rolls due to the rotation of the roller cage 34. Each backing roll comprises concentric inner rings 105, alternate with eccentric inner rings 106, such that the outer rings 102 mounted on rings 106 support the working rolls and the outer rings 101 mounted on rings 105 bear on a supporting body 20. The rings 102 are wider than the rings 101 and in each pair of backing rolls the wider rings 102 are offset, thereby reducing the tendency to form grooves in the working roll face.

Title: Method of reducing the coefficient of friction of elastomer surfaces
IPC: C08J7/12
Filed: 1965-01-13
Abstract: A method of reducing the coefficient of friction at surfaces of cured elastomeric products consists substantially of contacting the surfaces to be treated with at least one compound capable of addition polymerization and either (a) subjecting the contacted surfaces to ultra-violet or gamma radiation, or (b) incorporating a thermal polymerization initiator into the contacting compound and subjecting the contacted surfaces to the action of heat, the steps (a) or (b) being carried out in a manner to cause chemical combination and/or physical integration at the said surfaces of the contacting compounds with the elastomeric material and to cause polymerization of the contacting compounds. The elastomeric materials, e.g. elastomers containing residual unsaturation such as natural rubber, neoprene, nitrile rubber, SBR and polybutadienes and virtually saturated elastomers such as butyl rubber, silicone rubber, ethylene-propylene rubbers, and polyurethanes are treated with vinyl and vinylidene monomers or oligomers.  The unsaturated elastomers may be treated with fluorine- or chlorine-containing monomers.  In the examples, slabs of the elastomers are washed with soap and water and rinsed with acetone prior to being soaked in monomer or monomer solution and exposed to U.V. light or heated.  The elastomers, monomers, solvents and catalysts used are as follows: (1) natural rubber and styrene, (2) neoprene and methyl methacrylate, (3) SBR and n-butyl acrylate, (4) natural rubber, ethyl acrylate and benzoyl peroxide, (5) acrylonitrile rubber, acrylic acid and benzoyl peroxide, (6) natural rubber, methyl acrylate and azobisisobutyronitrile, (7) natural rubber, n-perfluorobutyl acrylate and benzene, (8) natural rubber, perfluoropropylene and toluene, (9) acrylonitrile rubber, perfluoropropylene, toluene and benzoyl peroxide, (10) natural rubber, n-perfluorobutyl acrylate, toluene and benzoyl peroxide, (11) acrylonitrile rubber, n-perfluorobutyl acrylate, toluene and azobisisobutyronitrile, (12) neoprene, perfluoropropylene, toluene and azobisisobutyronitrile, (13) to (15) natural rubbers acrylonitrile rubber or neoprene and perchloroethylene and (16) to (18) natural rubber, neoprene or SBR and trichloroethylene.  In Examples 13 to 18, the soaking of the slab in monomer and exposure to U.V. light are repeated.
