Title: Storage Means for Receiving Rolled Material
Inventor: HEIN EWALD
IPC: B21C47/14
Filed: 1967-09-20
Abstract: 1,154,280. Winding and unwinding wire. SIEMAG SIEGENER MASCHINENBAU G.m.b.H. 20 Sept., 1967, No. 42790/67. Heading B3E. A storage means for receiving rolled material comprises a rotatable coiling arm and a receiving drum on to which the arm can lay the material and is characterized by run-out means whereby the rolled material is taken off the drum in a direction tangential to the drum surface and in that the coiling arm and the drum are rotatable in opposite directions. The material is wound on to a drum 1 by a rotating arm 2 which rotates about an axis coaxial with the drum axis, and is driven by means 5. The coiling arm 2 rotates with the coiling head 3 and sweeps round the conical wall of a cover, the large end of which is adjacent the drum. The material is withdrawn tangentially from the drum through an outlet 8, which has one side parallel to the conical wall of the cover and the other side in the plane of the end of the drum remote from the laying arm. The wire is drawn off by a unit 6 and is guided under a roller 9, the rotation of the drum being due to the pull of the wire. If the speed of the coiling arm exceeds the rotary speed of the drum then material accumulates on the drum. The capacity of the drum is such that a complete length of rolled material can be accumulated on the drum, which is surrounded by a casing 7 for heating or cooling the material.

Abstract: 1,102,462. Ion sources. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 27 Oct., 1964 [31 Oct., 1963], No. 43063/63. Heading HID. In a mass spectrometer ion source arrangements for controllably cooling the metal walls of the ionization chamber in which sample material is present in vapour form include supporting the chamber 1, Fig. 1, by means of heat conducting plates 3, 4 on a cooling block or heat sink 5 into which cooling ducts 11,12 extend, or the ducts 11, 12 may extend through the block 5 into the ionization chamber. The cooling ducts may be in thermal contact with the chamber walls. In an alternative embodiment a thermo-electric cooling device is mounted in thermal contact with a heat sink supporting the ionization chamber or against a wall of the ionization chamber. In a further embodiment, Fig. 4, the ionization chamber 20 is mounted for ready removal on a sliding bar 21 and a heat sink in the form of a block 23 with an arcuate surface may be moved by means of a lever and cam mechanism 28, 29 into or out of contact with the bar 21.

Abstract: 1,119,830. Two-part couplings. HACKBRIDGE-FARADAY ELECTRICS Ltd., J. D. MORTON, and B. J. DIXON. 22 Oct., 1965 [23, Oct., 1964], No. 43233/64. Heading H2E. A housing 1 of a cable coupling device contains a plurality of contacts 6 with terminals 7, each housed and retained within a separate insulating sleeve 8 and further shielded from all other contacts by a metal barrier 10 extending longitudinally in the housing, and having a web to locate the sleeves 8. The barrier is earthed to ensure that any damage can result only in an earth fault. A Y-shaped barrier 11 may be employed for three contacts, fin portions 14 and 17 extending either side of a transverse web portion 12 adapted to slide within the housing. The fins 14 have securing bosses 15 such that retaining screws 16 clamp the metal barrier 10 and the sleeves 8 in the body. The fins 17 have an insulating jacket 18 where the terminals 7 extend beyond the sleeves 8, and terminals 19 to which the metal sheath 20 of the cable is connected. The contacts 6 are secured to the terminals 7 using a spider-shaped fixing ring 5c. A filling plug 22 and a vent 23 facilitate insertion of a sealing compound when a cable gland or end cover is secured to a flange 4. Alternatively, Figs. 4 and 5 (not shown), the metal barrier may be formed as a block of metal with holes to accommodate the sleeves 8. An earthed plate 26, suitably apertured, retains the sleeves and the contacts in the sleeves, and has terminals 19 for the cable screens. The plug contacts of the mating device has a shroud 29 and the two devices may be secured together by a retaining ring 2a. A shorter pair of contacts connected in a control circuit engage only when the other contacts are properly mated. Polarizing earthing pins 30, Fig. 5 (not shown), may also be employed.

Abstract: 1446044 Automatic control of temperature HENSBY INVESTMENTS PTY Ltd 14 Sept 1973 [24 Nov 1972] 43270/73 Heading G3R An electric soldering iron includes an electric heating element and a resistive temperature sensing element both wound around a barrel and an automatic temperature control circuit which may be contained within the iron handle. In Fig. 1, the heater element 8 and SCR 9 are connected across an A.C. supply. The sensor 11  and a desired temperature setting resistor 12 form a voltage divider arranged to trigger the SCR 9 when the sensed temperature falls below a predetermined value. A capacitor 18 causes the divider current to lead the supply voltage S whereby the SCR will conduct when the voltage across it is relatively low - thereby to minimize radio inter-  ference. Diodes 16, 17 provide ambient temperature compensation. In another embodiment Fig. 3 the sensor and setting resistor are connected in a bridge circuit. A diode 24 balances bias voltage inherent in the SCR. A diode 23 balances the effect on the bridge of the diode 24. Diodes 24 and 26 limit current through the sensor 11 when SCR 9 is ON.

The flaps are shaped so as to define a convergent nozzle portion terminating in a throat when the fan blades are in the normal forward thrust position. Antiswirl guide vanes 24 are disposed in the fan duct downstream of the inlet to the core engine. The nozzle flaps 26 are movable to an outward position in which they define a bell-mouth air inlet when the fan blades are moved to the reverse pitch position.

A spark arrester for an internal combustion engine comprises a chamber 10, Fig. 1, having a coaxial outlet conduit 13 and a closed coaxial member 15 which project into the chamber and co-operate with the walls of the chamber to form an upper and lower annulus. An inlet pipe 17 from the engine exhaust header 20 tangentially intersects the chamber and member 15 and extends the vertical height of the lower annulus and a helical plate 24 forms a floor for the lower annulus which deflects the incoming exhaust products for abrading or combustion against the walls of the chamber. A transverse concave baffle 29 may be placed at the outlet of the conduit to further deflect the products and a drain 33 for heavy combustible liquids may be placed in the bottom of the pipe adjacent the lower end 25 of the helical plate. In a modification a conduit 131, Fig. 5, is provided in the chamber having perforations 35 intermediate its length for the exhaustion of gaseous and small particles of solid products.
