Title: Device for manufacturing a pre-impregnated oil-filled cable having a metal sheath
IPC: B21C23/26
Filed: 1964-11-12
Abstract: Apparatus for manufacturing a pre-impregnated oil-filled cable having an oversized sheath 16, e.g. of aluminium which is subsequently drawn or corrugated on to the cable core, has a double-walled tube 6 disposed within the extruding die 23 so as to allow impregnating oil 7 to act as a cooling medium between the cable core and the extruding die and the hot metal sheath. The cooling medium is formed partly by oil vapour 25 caused by the heat from the extrusion die and partly by a reverse flow of oil through an intermediate space 9 between the walls of tube 6. The oil vapour is prevented from entering the finished cable by a flow of oil 7 from the centre of tube 6 through slots 8 in the end of the tube into the intermediate space 9. The oil is obtained from an impregnating vessel 1 and is pumped from the space 9 through a cleaning and degassing system so as to return the oil to the impregnating vessel or to an oil reservoir. Water cooling is also applied at 24. To start the process, some sheath 16 is formed and the sheath, tubes 6 and 3 are evacuated by means of a vacuum pump 19 or 191 applied to an end cap 17 or to tube 3 respectively. A metal wire 22 is attached to the cap 17 and to the end of the cable core 21 so that the core is pulled through the extruding die as the sheathing process commences. In a modified extruder 2, Fig. 2 (not shown), which may fit a Schloemann aluminium press, the tube 6 is positioned so that oil leaving the intermediate space 9 passes between an outer water-cooled shield 27 and an inner tube before entering connecting tube 3.

Title: Apparatus for controlling the operation of fluid operated jacks required to be moved in synchronism
IPC: B66F7/20
Filed: 1965-07-17
Abstract: A hoisting apparatus comprises two hydraulic jacks V1, V2 whose pistons P1, P2 are fixed to the ground in a vertical position and whose cylinders C1, C2 are supplied with pressure liquid through pipes a1, a2. A load supporting platform is represented by a crossmember T attached to the cylinders C1, C2 by pin joints A1, A2. In order to cause the jacks to move together so as to keep the crossmember T horizontal each cylinder C1, C2 comprises a bleed pipe b1, b2, respectively, connected to a valve 1 fixed to the cylinder C1. The valve 1 consists of a body 6 with a bore 7 into which extend ducts 8, 9, 10, 101. A slide member 11 extended by a rod 12 is connected by a rod 3 and pivoted lever 4 to the cross-member T. If the jack V1 rises more rapidly than the jack V2 the lever 4 is pivoted clockwise by the tilting of the cross-member T so that the slide member 11 moves to the left to connect the bleed orifice b 1 to tank through the duets 8, 101 to slow down the jack V1. On descent the system operates in the same way, the bleed orifice of the lagging jack being connected to tank to accelerate its descent. The means sensitive to the relative movement of the jacks V1, V2 may be two micro-contactors (13), (14), Fig. 3 (not shown): a mercury contactor (15), Fig.4 (not shown) photo-sensitive cells (26), (27), Fig. 5 (not shown), or an arm (28), Fig. 6 (not shown), may act directly on micro-contactors. In a platform raised by four jacks (not shown) the horizontality of the platform may be maintained by combining the jacks in pairs, each jack being provided with two synchronizing devices, one of which controls the tilt of a transverse cross member, and the other the tilt of a longitudinal cross-member.

Title: Apparatus and method for manufacture of float glass with restricted lateral spread
IPC: C03B18/06
Filed: 1966-12-12
Abstract: In the manufacture of glass using the "float" technique such as described in Specifications 769,692 and 893,663 the configuration of a transverse cross-section of the glass ribbon is controlled by containing the glass when it initially arrives on the molten metal bath and thereby conserving the heat so that the glass is of low viscosity as a step precedent to establishing a layer on said bath, whereby the glass in the layer flowing laterally to the limit of its free flow is developed into a ribbon of glass of uniform thickness. Molten glass flows freely from a spout on to a molten metal bath and is contained between a pair of spaced refractory walls 15 (Fig. 2, not shown), which walls are parallel both to themselves and the longitudinal axis of the molten metal bath. These walls extend for a distance such as 2 1/2 ft. along the length of the tank. By being so confined between these walls the molten glass retains its heat longer than in previous methods and thereby acquires a uniform configuration and temperature. Further extension walls 19, pivoted to the ends of walls 15 remote from the spout 4 and floating on the molten metal bath and splayed at an angle to the walls 15 further restrict the ribbon formation by limiting the lateral extent of free flow of the molten glass. These extensions are formed of a material wetted by the glass but at their free ends have inlays 20 of a non-wetting material such as carbon. These extensions 19 are water-cooled, the cooling pipes 24a also being used to set the angle at which the extensions are splayed. This angle is preferably 25 degrees.

Title: Apparatus for producing continuous rows of sliding clasp fastener link members
IPC: B29D5/04
Filed: 1967-12-12
Abstract: Apparatus for forming a plastics thread into a continuous row of sliding clasp fastener link members comprises a toothed wheel 1, a thread guide 8 which moves axially across the circumference of the wheel and radially at one or both sides of the wheel and an anvil at one or both sides of the wheel level with the base of the teeth 2 in wheel 1. The wheel 1 is shown in cross-section in Figs. 5 and 6 and from above in Fig. 2, the formed fastener being also shown in this figure. The thread guide has a raised portion 9 around the outlet of the thread channel 8 and a finger 11 which fits between two teeth 2 on wheel 1. In operation the thread guide 8 moves from left to right laying a thread 3 between the teeth 2. The thread guide is lowered radially so that finger 11 is located between teeth 2 and the raised portion 9 stamps the thread against the anvil 4 forming a thickened portion 3c. At the same time, the finger 11 presses the thread against the raised portion 5 between the teeth and forms another dent in the thread. The thread guide is then moved radially and moved to the left to the position shown in Fig. 6, the flattened portion 3c forming the fastener member. The toothed wheel is advanced by one tooth and the process is repeated yielding a fastener of the type shown in Fig. 2. The thread 3 may be softened by heating during the process. In an alternative embodiment, the wheel 1 comprises two toothed sections with a space between them and an anvil is placed on both sides of the wheel, the resulting link member having the cross-section of a prone figure eight. The depression formed by raised portion 5 assists in fastening the fastener to a stringer.

Title: Method of and apparatus for making an interlaced yarn
IPC: D02J1/08
Filed: 1968-06-27
Abstract: A running multifilament bundle is formed into yarn by moving it laterally into and out of contact with a lateral interlacing, and perhaps heating, jet of fluid e.g. air, nitrogen, carbon dioxide, steam or water, the frequency and direction of the contact of the filaments and jet being such as to cause continuous interlacing of the yarn and the tension of the bundle being such as to prevent formation of crunodal loops in the filaments, although the tension may be abruptly intermittently relaxed in synchronism with the bundle making contact with the jet. In a converted ring-or capspinning machine, a running bundle, passing through a combined tubular guide and jet apparatus (located on the axis of a yarncollecting bobbin) to a ring-traveller or lower edge of a cap, generates a balloon which is deflected, say once in each cycle, by a projecting edge of a deflector plate inwardly of the balloon and released when a segment thereof is in the path of the jet.

Title: Apparatus and method for regulating the temperature of an electrical furnace
IPC: G05D23/22
Filed: 1968-06-28
Abstract: An automatic control system, particularly for a diffusion furnace for semi-conductor doping having a proportional + integral action has the integral action suppressed or reduced during an increase of the rate of change of the error signal. A furnace 1 has the output from a detecting thermocouple 4 compared with a reference in a difference amplifier 5 the output from which is passed through a further amplifier 3 to control the firing angle of a thyristor unit 2 controlling heater current. Integral action is provided by a circuit R1, C the latter being shunted by a N. T. C. thermistor R2 heated by a separate resistor 9 fed from a differentiating circuit 6, so that when the rate of change of error signal is large thermistor R2 has a low value thus shunting capacitor C. In an alternative arrangement Fig. 4 (not shown) the capacitor C is shuntable by a contact of a relay energized from differentiating circuit 6. The contact may have a series resistor (18) to reduce the shunting action. The arrangement is stated to reduce overshoot in automatic control systems having a large time lag, and may be applied to controlled path drives in machine tools. The system may be applied to a mechanical control arrangement, Fig. 5 (not shown).

Patent ES-434314-A1 (ES)
Title: High voltage protection circuit
IPC: H04N3/20
Filed: 1975-01-31
Abstract: An integrated thyristor-rectifier (ITR) replaces the conventional damper diode in a television deflection system. The damper diode function is performed by the rectifier portion of the ITR, the thyristor being reverse biased during the damping interval. The forward breakover voltage characteristic of the thyristor portion of the ITR insures that the cathode of the damper-rectifier portion of the ITR will not rise to a higher voltage than the thyristor's forward breakover voltage above the cathode of the thyristor during the remaining portion of the deflection cycle. If the cathode of the damper-rectifier rises above the thyristor forward breakover voltage, the thyristor begins to conduct heavily causing the deflection current to decay rapidly and rendering the television display unviewable while simultaneously limiting the generated high voltage.
