Title: Improvements relating to folding windows
IPC: E05D15/26
Filed: 1939-05-19
Abstract: 529,003. Windows. BACHTOLD, M. May 19, 1939, No. 14954. [Class 20 (iii)] A suspension means for the sashes of windows of the folding-leaf type shown in Fig. 2, comprises a right angled strap 11, Fig. 4, which is attached to an upper corner of a sash, e.g., 3, by screws, and has a lug 12, to which is pivotally attached an angle-piece 16, 17 carrying a roller 10, which runs on a track fixed horizontally along the upper edge of the window frame. The lug 12 is bored vertically to two diameters 13, 14, the larger bore 14 being lowermost. A bolt 18 passes through the lug, the head of the bolt being contained in the bore 14 and bearing against the shoulder formed by the two bores 13, 14, and the threaded portion of the bolt engages in a tapped hole in the horizontal part 17 of the angle-piece. The vertical part 16 of the angle-piece carries a pin 15 on which is mounted the roller 10. The bolt 18 allows for vertical adjustment of the sash and acts also as a pivot, the angle-piece 16, 17 turning on the thread of the bolt when the window is opened or closed. Rotation of the bolt 18 is prevented by a cottarpin 19. The vertical adjustment of the window sash is thus prevented from being disturbed accidentally. Such suspension fittings are attached to the sashes at alternate hinge lines. e.g. at the junctions of sashes 2, 3 and 4, 5, Fig. 2.

Title: Improvements in and relating to thin magnetic film elements
IPC: H03K17/84
Filed: 1961-04-26
Abstract: A thin magnetic film element comprises a first zone I, Fig. 3, surrounded, at least where the periphery of the zone I is not parallel to <PICT:0966613/C6-C7/1> <PICT:0966613/C6-C7/2> <PICT:0966613/C6-C7/3> the direction of easy magnetization a, by a second zone III, the coercive force required for wall motion being greater in the second zone than in the first zone.  The element may have a third zone II wherein the said coercive force is less than that in the second zone.  In the arrangement shown in Fig. 3 the zone III comprises gold or copper vaporized on and diffused by heat treatment into the nickel-iron film comprising zones I and II. The copper or gold may also be electrodeposited. In a similar arrangement, Fig. 4 (not shown), the element is made by first applying a ring shaped aluminium layer to a glass substrate, or by etching, grinding or electron bombardment of the substrate and then applying a nickel-iron film by evaporation.  Uniaxial anisotropy is obtained by magnetizing the element parallel to the plane of the film. In an alternative arrangement, Fig. 5, the difference in coercive force between the three zones is achieved by varying the layer thicknesses.  In this 80:20 Ni:Fe element the thickness of the zone II is less than 700<\>rA and the thickness of layer I is greater than 1500<\>rA. In the single "delayed" switching element shown in Fig. 7 having two zone II regions A, B "read in" produced by the field H2 of the coil 4 results in rotational switching of zone II at A.  The domain wall which then appears at the left hand end of middle region C of zone I is caused to travel along this region by a field H1 at a speed depending on the magnitude of this field.  When the domain wall reaches the transition from region C of zone I to region B of zone I it is accelerated by the coil 6 which produces a field insufficient to switch region B of zone I by domain rotation but large enough to produce high speed wall motion.  Region B of zone I is then quickly switched and an output signal is produced in winding 7.

Filed: 1942-11-04
Abstract: 559,438. Manual exchange systems. GRAHAM & CO., Ltd., A., and VAUGHAN C. H. Nov. 4,1942, No. 15553. [Class 40 (iv)] In a system having a manual switchboard of the cordless type, each outstation is arranged like B in Specification 552,215 with a rectifier which normally opposes the flow of line current and is cut out when the subscriber lifts his receiver to make a call, and a subscriber is called by reversal of the battery connections to the line to operate a buzzer in series with the rectifier. Whenever the operator's instrument is connected to a line tone current is injected thereinto as a warning to subscribers who may not wish their conversation to be overheard. Each line is led by way of a terminal board TB and fuse board FB, Fig. 3, to a line unit, Fig. 2, which is provided with keys AK .. FK, one for each connecting link, and a reversing key CLK for calling the outstation. A calling and supervisory lamp CL is controlled by a relay R, which also controls high note and low note buzzers HN, LN and associated receivers HNR, LNR, Fig. 1 serving respectively as calling and clearing devices. Lamps A .. F for indicating the idle or busy condition of the links are controlled by chain circuits over corresponding keys in the line units. The operator's set OS is connected to any line by plugging into a jack J, the springs of which control a starting circuit for the tone generator TG, Fig. 3. The latter comprises a motor M which generates a tone or ticking sound by slowly interrupting a circuit coupled to the operator's set by a transformer TR. A connection between two or more subscribers is established by the operation of corresponding keys AK .. FK in the line units to connect the lines through condensers K to the same link. The capacity of the exchange may be increased by providing a number of sections similar to the switchboard described with a number of junctions interconnecting them, a junction key being associated with each link on each section. The switchboard may take the form of a shallow box-like structure with a front panel which is hinged to open face downwards.

Title: Improvements in and relating to protective devices for liquid immersed electrical apparatus
IPC: H02H5/06
Filed: 1949-06-14
Abstract: 665,216. Thermal switches; pneumatic actuation of switches; protective cut-out systems. BRITISH THOMSON-HOUSTON CO., Ltd. June 14, 1949. [June 18, 1948] No. 15805/49. Class 38 (v). Liquid-immersed electric apparatus 1, e.g. transformers or reactors are protected against fault by a switch 27 actuated by means 7 responsive to the pressure and temperature of the liquid. A diaphragm 8 responsive to pressure is connected by a rod 10 to a strap 25 surrounding, and connected to one end of, a thermally responsive bellows 9, the other end of which is fixed. Normally the two devices are arranged to counter-balance each other so that with normal pressure increases accompanied by normal temperature increases, the switch 27 is not actuated. If however, the pressure increases rapidly due to a fault in the apparatus and there is therefore substantially no temperature increase, the diaphragm overpowers the bellows and operates the switch. The latter is of the type having two "on" positions and a central "off" position which it normally occupies, so that increase of pressure moves the switch to one "on" position to energise a trip coil 29. The switch is moved to its other "on" position to energise a signal 30 as a result of a fall in pressure due to leakage. The surface area of the diaphragm may be varied by changing the size of gaskets 12 and/or 13.

Title: Improvements in effecting chemical reactions in gases by means of electrical discharges
IPC: C07C2/80
Filed: 1928-05-31
Abstract: 317,558. Hull, P. H., and Imperial Chemical Industries, Ltd. May 31, 1928. Gases, treating with electric discharge.-In the production of acetylene by the passage of gaseous hydrocarbons through an electric discharge, the gases are passed into the discharge zone with a velocity of 800-900 feet per second so that a high degree of turbulence is produced. The treated gases are rapidly conducted from the discharge zone. The arc is struck between the hollow electrode 2 and the rod electrode 1. The gases are introduced through a tube 3 arranged co-axially with the electrode 2 and pass through the arc into the chamber 4. The gases may return through the arc and pass away through the annular space between the tube and electrode 2. The electrodes are of carbon and the hollow arc may be rotated. The chamber 4 may be of aluminium. Coke oven gas freed from sulphur compounds and containing 25-35 per cent of methane is passed through an arc operating at 4000 volts and 40 cycles and yields 3-5 per cent of acetylene which passes to an absorption tower as described in Specification 302,515, [Class 2 (iii), Dyes &c.].
