Title: Process for manufacturing footwear from curable materials
IPC: B29C43/12
Filed: 1960-08-11
Abstract: 932,216. Making boots &c. G. MONDELLO, and T. BOCCOLI. Aug. 11, 1960 [Aug. 11, 1959; Aug. 14, 1959], No. 27884/60. Class 17 (2). [Also in Group V] A process for manufacturing articles of footwear comprises forming a sole having a flange extending laterally from the top edge of the sole, inserting the sole into a mould such that the flange forms a seal between adjacent mould pieces and subsequently moulding the upper on to the sole using a heat-curable material. The sole 18 with the flange 16 is prepared in an auxiliary mould and partly or wholly prevulcanized, though not necessarily pressed to exactly its correct proportions. An inflatable mould core 8 has a rigid plug 4 and a valve 5, and is reinforced at the base with woven fabric with the threads at 45 degrees to the longitudinal axis of the sole. The core is covered with fabric and/or reinforcing elements-i.e. felted, non-slip rubber-and a heat-curable material. This material has a higher sulphur content than that of the sole so that the diffusion from the upper to the sole ensures a good bond between the two. The sole and core are placed in the mould and the latter is inflated. The upper is heated for about five minutes depending on the materials used &c., or the mould may be preheated. Excess material is expelled from the top of the boot. A welt may be imitated by having corresponding indentations in the base of the upper mould piece. The flange 16 can be removed by machining while the top edge can be cut round to give the correct height or inclination. The upper may be partly formed of non heat-curable material, e.g. heat resistant leather which may have had a special surface treatment. The sole may be thicker at the edge than at the centre. The thickness of the upper may be varied a little, e.g. between 1¢ and 3 mm., by providing cavities in the outer mould pieces. The colour of the sole and upper may be different.

Abstract: 1,130,964. Accumulators. W. GREUTERT. 23 June, 1966 [23 June, 1965], No. 28093/66. Heading H1B. In an accumulator comprising a housing 1 with an opening 2, a negative electrode composed of layers 3 and 4 and a positive electrode 5 facing each other without a separator being therebetween, components 3, 4, 5 being impregnated with electrolyte, e.g. aqueous KOH, when in the discharge stage layer 4 consists of a metal compound which does not conduct an electric current and is capable of being changed to a conductive mass when the accumulator is charged and of being rechanged again when the accumulator is discharged, the layer 4 making contact at least over a part of its surface with electrode 5. Layer 3 consists of a metal carrier frame, e.g. sintered Ni, into which is embedded a part of the active mass, e.g. Cd(OH) 2 . Layer 4 can be Cd(OH) 2 , in the form of loose or compressed powder with or without a binder, and may contain brightening agents, e.g. glycerine, boric acid, silicates, phosphates, gelatine and coumarin. Electrode 5 may also comprise a metal frame in which is embedded a positive electrode mass, e.g. Ni(OH) 2  or NiO, or be formed entirely of compressed NiO, with or without Ni or graphite. During charging Cd(OH) 2  in metal frame 3 is changed to Cd whilst NiO in 5 is oxidized to Ni 2 O 3 , then Cd(OH) 2  in 4 changes progressively to Cd and the boundary layer 8 in contact with 5 has been changed to Cd so that a short-circuit occurs, an automatic contact-breaking device in the external circuit can be used for terminating charging, and the particles in contact along the boundary surface neutralize their opposite charges with immediate formation of Cd(OH) 2  and cessation of the inner short-circuit. If desired electrode 5 may be composed of two layers, and the electrodes can be composed of other substances, e.g. the negative electrode can contain Zn, Fe or other base metals or compounds, and the positive electrode can contain Ag, Cu, Co or Hg or their compounds. Other metals and non-aqueous electrolytes are mentioned.

IPC: G01H3/10
Filed: 1962-07-24
Abstract: 1,003,985. Photo-electric indicating devices. UNITED BRISTOL HOSPITALS. July 24, 1963 [July 24, 1962], No.28410/62. Heading G1A. [Also in Division H4] In an arrangement for measuring the intensity of the radiation produced by an ultrasonic transducer the radiation from the latter 10, (Fig. 1) which is immersed in a water filled tank 12, is directed by reflection at 16 towards a radiationpressure sensitive member 18 carried by an arm 24 mounted on the moving coil 20 of a moving coil instrument 22. Movement of arm 24 caused by radiation pressure on member 18 is arranged to vary the amount of light falling on a photo-transistor 30 (Fig. 2) which together with a second phototransistor 32 subjected to constant light from the same source (Fig. 3, not shown) form two arms of a bridge circuit the output of which is supplied via a D.C. transistor amplifier 48 to one side of the coil 20 and other side of which is supplied from a D. C. source of opposite polarity via a circuit including a milliampermeter 52. Thus, as the bridge goes out of balance due to movement of arm 24, the output of transistor 48 is reduced and current flows via the circuit including milliampermeter 52 which acts to rotate coil 20 in a direction which returns the arm 24 (and member 18) to the initial position. The current indicated by meter 52 is thus a measure of the radiation pressure and this may be determined directly by suitable calibration. In the well position the member 18 is arranged to hang with a slight inclination to the vertical in order to avoid errors due to buoyancy forces caused by bubbles sticking to it and to reduce the effect of standing waves This inclination may be set by adjustment of potentiometer 60 which thus allows compensation to be effected for departure from the horizontal of the surface on which the instrument rests.

Class 109 In a method of manufacture of a multi-core electric cable, the cable cores are progressively advanced to an assembly point where they are assembled together to form a group of parallel cores, and the group of cores is progressively fed towards and coiled down on a support surface to cause the cores to become helically laid up about the central axis of the group, the support surfaces being rotatable about an axis passing through the coil thereon and being maintained stationary or .rotated at constant or varying speed to determine the length of lay imparted to the group of cores. Multi-core electric cable is made from cores assembled in parallel relationship by coiling down the group of cores on a rotatable turntable, the coiling down action imparting twist to the group of cores. Stranded conductor 3, Fig. 1, drawn by a capstan 4 from a stranding machine 1 passes through a storage device 5 comprising two sets 7, 8 of grooved pulleys one of which 7, is movable towards and away from the other, and is coiled down on a power-driven turntabel 2 which may be rotated or not according to the amount of twist reauired in the conductor 3. As shown in Fig. 2, - the conductor 3 is drawn off the turntable 2 and passed through an insulating machine 10 where is it lapped with screening tapes, impregnated paper tapes and metal, plastic or water-proofed paper. A capstan 12 draws the core 3 from the machine 10 and passes it to a storage device 13 similar to the device 5 of Fig. 1, hence it is coiled down on a turntable 15. Several lengths of core are simultaneously withdrawn from turntables e.g. 14, 15, Fig. 4, with padding threads 26 from reels 25 and pass through a closing die 21 where they are assembled in parallel relationship. A double capstan drive 29 passes the group 27 of cores, taped by a taping head 28, to a storage device 30 similar to the device 13 of Fig. 2 and thence to a lead press 31 through which it is drawn by an overdriven caterpillar haul. off 35 coiling down action inserting the twist to and coiled down on a turntable 34, the lay-up the sheathed group 32 of cores. This twist may be augmented by suitably rotating the turntable 34 and the drive of the turntable may be variable to correspond to the varying diameter of the coil on the turntable. Alternatively, the cores such as 18, 19 may be fed to the die 21 from the core-making apparatus and the laying-up of the cores carried out as a continuous process. Specification 706,726 is referred to.
