Title: An arrangement for maintaining constant the tension of web material during winding and unwinding
Inventor: FAZIS HERMANN
IPC: B65H23/06
Filed: 1955-10-20
Abstract: 779,691. Winding and unwinding webs. ROTHSCHILD, D. Oct. 20, 1955, No. 29963/55. Class 100(1) An arrangement, for maintaining constant the tension of a web as it is being wound on to or unwound from a beam wherein the beam rests at one end on a support, has means for transforming at least a fraction of the thrust exerted by the weight of the beam on the support into an operative force acting on adustment means for adjusting the tension to maintain it substantially constant as the weight of the beam alters, control means being provided to permit variation if desired, of the magnitude of the fraction of the thrust so transformed. As shown, a beam 5 on which material may be wound or unwound from is carried by a U-shaped supporting member 4 on the end of a stub shaft 3 which rocks about the centre 7 of a self-aligning ball bearing 2. A handwheel 28 which can rock about an axis 29 into a vertical position retains the beam 5 in the recess 4a formed by the U-shaped cross-section of the member 4. The handwheel is moved to locking position manually or when the shaft 3 is rotated by an abutment lb. When it is required to remove the beam 5 the handwheel can be rocked into engagement with a bevelled face 1a when the beam is uppermost in the recess 4a. The shaft 3 extends through a carrier 9 within a casing 1, the carrier 9 having a curved surface engaged by a roller 11. The roller 11 is mounted in a fork 31 secured to an adjusting lever 12, the fork 31 being mounted on aligned pivots 35 fixed in the casing 1. The axis 13 of the pivots 35 crosses the axis of the shaft 3 which is journalled within the casing 9 by bearings 8 and 8a positioned on either side of a thrust bearing 19. The lever 12 may be locked in various positions about the pivots 35 by a spring pressed pin 15 which can engage notches 14 in the casing 1. The carrier 9 is urged upwardly by a spring 40 into engagement with the roller 11. As winding proceeds, the weight of the beam increases thus increasing the components V and H of a force P exerted by the carrier 9 on the roller 11. The vertical component V balances the part of the weight acting on the support 4, while the horizontal component H is transmitted through a screw 16 to a member 17 and through the bearings 9 and 8 to a member 21. The member 21 forces a slidable but non-rotatable plate 22 against a friction lining 24, thereby causing a wheel 25 to transmit a higher torque to a clutch plate 22a secured to the shaft 3. The wheel 25 is slidable on the shaft 3 and is driven from a chain wheel 26 by a pin 27. The wheel 25, plate 22a, wheel 26 and a plate 43 carry friction linings 24a, 24b, 24c respectively. In the case of unwinding material from the beam, the wheel 26 is held stationary such that the shaft 3 is braked according to the weight of the material on the beam 5. In both cases the adjustment of the driving or braking torque maintains the material tension substantially constant.

Title: Improvements in or relating to circuit-arrangements for automatic signalling systems
IPC: E06B3/34
Filed: 1956-10-02
Abstract: 828,168. Automatic exchange systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. Oct. 2, 1956 [Oct. 5, 1955], No. 29989/56. Class 40 (4). Subscribers' line circuits LC can be connected to connecting circuits VC over a gasdischarge network, one of the connecting circuits being marked idle by an associated trigger circuit in an active state, while by virtue of a lock-out arrangement all other connecting circuits are marked busy with their associated trigger circuits in a passive state, initiation of a call from a subscriber's line circuit setting up a discharge path to the connecting circuit marked idle which when seized is marked busy by setting its associated trigger circuit to a passive state. Each line circuit LC is connected over a gas-discharge tube B to each connecting circuit VC. In each connecting circuit VC a discharge tube BV is connected through a common resistor R4 to positive potential such that only one tube BV can conduct at any time. When a tube BV, say BV1, conducts a transistor TR1 in the connecting circuit also conducts and by means of the resistor chain R5, R6, R7, puts a priming potential on the trigger electrodes of the tubes B multipled to the connecting circuit. If a subscriber, say AB1, lifts his receiver, a pulse across transformer T1 is applied to the cathodes of the tubes B11, B12, &c. multipled to the subscriber's line circuit of which B11 is primed and in consequence fires. Current through B11 flows through and inductor L1 and a resistor R3 dropping the potential of the junction P between them and dropping the potential of the multipled point MV1 to guard the connecting circuit VC1 against intrusion. The drop in potential at junction P cause a negative pulse from capacitor C3 and rectifier G2 to be applied to the anode of tube BV1 which is thereby extinguished increasing the voltages from the chain R4, R8, R9 on the anodes and trigger electrodes of all other tubes BV one of which ignites. The trigger electrode f of tube BV1 is no longer primed due to the drop in potential at the point P which over the chain R10, R11, R12 cuts-off rectifier G1 and ensures that the tube BV1 cannot ignite until circuit VC1 is released. The subscriber's circuit is marked busy by current in resistor R2 putting a potential on the multipled point ML1.

Filed: 1938-10-18
Abstract: 519,472. Concentrating gold-bearing ores &c. NEVILL, P. W. Oct. 18, 1938, No. 30093. [Class 82 (ii)] Gold-bearing ores, slimes, residues, &c. are concentrated by subjecting a pulp of the ore &c. to treatment with the gaseous products of the incomplete combustion of a hydrocarbon or hydrocarbons in the presence of a soluble copper compound, and at the same time or subsequently subjecting the pulp to froth flotation. The soluble copper compound may be added to the pulp or it may be present naturally in the ore &c. or be formed from constituents present in the ore. Examples are given of the treatment of ores in which copper sulphate and common salt are added to the pulp which is then subjected to flotation concentration in the presence of the gaseous product of the incomplete combustion of kerosene. Flotation reagents are added, e.g. xanthate, tar, turpentine, and cresol. The copper present in the ore is concentrated with the gold.

Title: Protective treatment of zinc surfaces
Inventor: FRY HANNO
IPC: C25D11/00
Filed: 1955-10-21
Abstract: 813,994. Anodizing zinc and zinc alloys. BRITISH NON-FERROUS METALS RESEARCH ASSOCIATION. Jan. 17, 1957 [Oct. 21, 1955], No. 30168/55. Class 41. A protective surface coating is formed on zinc or zinc alloy by anodizing at 10 to 300 volts in a dilute aqueous solution of an oxide or hydroxide of an alkali metal or alkaline earth metal or of ammonia together with at least one alkali metal salt of an acid which forms a sparingly soluble or insoluble zinc salt, e.g. carbonic, silicic, boric, phosphoric, oxalic, or succinic acid, this first treatment being followed by a second treatment at elevated temperature and pressure, e.g. 150‹ C. and 50 1b./sq. inch, with a dilute solution of an alkali metal silicate and optionally of an alkali metal salt of another acid which forms a sparingly soluble or insoluble zinc salt. In a modification, the anodizing treatment is repeated substituting for the alkali metal salt used in the first treatment an alkali metal salt of a different acid which forms a sparingly soluble zinc salt, followed if desired by the said second treatment at elevated temperature and pressure. In examples zinc is anodized in a caustic soda-sodium carbonate solution at an applied potential rising from 15 to 110 volts and is then autoclaved in a sodium silicate solution made alkaline with caustic soda; for diecast zinc-base alloy the treatment is similar but the water-glass autoclaving solution contains no caustic soda; while in the modified process omitting the autoclaving treatment, for pure zinc a second anodizing is effected in a solution of sodium borate, water glass and caustic soda at a voltage rising rapidly to 120 volts and then more slowly to 200 volts with accompanying sparking, while for a zinc base-aluminium-magnesium alloy the second anodizing is effected at a voltage rising to 230 volts in a similar solution containing less caustic soda. The Provisional Specification describes also processes in which after the first anodizing treatment the treated surface is boiled in a dilute aqueous solution of an alkali metal, alkali earth metal, or ammonium silicate, sulphide, or chromate, followed if desired by stoving at atmospheric pressure. Similar solutions may be used for a second anodizing treatment or for the autoclaving treatment.

Abstract: 785,772. Controlling aircraft. BOEING AIRPLANE CO. Oct. 21, 1955, No. 30184/55. Class 4. [Also in Group XXIX] A control surface operating mechanism for an aircraft having a movable aerofoil connected by a generally spanwise hinge to a fixed aerofoil comprises fore and aft disposed actuators mounted adjacent the hinge axis on one of said aerofoils with their ends or a member secured thereto abutting the adjacent edge of the other aerofoil along a line, and means for equally and simultaneously moving all said actuators to move the control surface about the hinge axis. As shown, in Figs. 1 and 2, the control surface 22 is provided with a spar 23 hinged by bolts 29 to members 17, 18 bolted to ribs 19, 20 together with a cylinder block 16, which contains two sets of bores 28, 30. A piston 31 slides in each bore, and two sets of rods 40 extend from the pistons to abut a plate 44 recessed at 45. The cylinders are connected by ducts 62, 63, and 46, 47, to a hydraulic valve contained in a valve block 48 secured to the block 16. The valve is controlled through links 50, 83, 77 and 73 by a control element 74. A follow-up signal is applied to link 83 by links 90, 87 and 85, to recentre the valve element when the surface 22 attains the position determined by the control element displacement. To prevent flutter, the valve used is such that both pistons are subjected constantly to some hydraulic pressure and when, for example, the upper cylinders 28 are fed with fluid under full pressure to move the surface clockwise, the lower pistons are pushed back against a lesser hydraulic pressure in cylinders 30 (see Group XXIX). In Fig. 9, the heads of the piston rods 40 are T-shaped as at 111, to distributed stresses evenly over the plate 44. The cylinder block 16 is covered by flexible panels 26 and 27 which co-operate with the skin of the surface 22 so as to leave no slot between the wing and the surface. In the modification of Figs. 7 and 8 (not shown), the outer ends of each set of rods 40 are connected to a spanwise extending member which abuts plate 44.
