Title: Automatic means for controlling sliding members such as windows, doors, and the like
IPC: E05C17/08
Filed: 1941-11-10
Abstract: 553,985. Controlling and fastening sliding windows ; stays for hinged windows. O'CONNOR, J. P. Nov. 10, 1941, Nos. 14441 and 14442. Convention dates, March 5 and Oct. 16. [Classes 44 and 65 (i)] A device for controlling relative sliding movement of two members, allowing free movement in one direction and in the other allowing slow movement but arresting quick movement, comprises a gravityactuated pivoted member 6 mounted on one relatively slidable member 4 having one arm 6c normally held clear of the path of teeth 2 on a rack mounted on the other relatively slidable member 1, by weighted arm 6a, and another arm shaped as a cam 6b which is actuated by each passing tooth to swing arm 6c into the path of the teeth. With slow movement member 6 oscillates, arm 6c managing to swing clear of the teeth, but with quicker movement, arm 6c fails to clear and makes paw-like engagement with a tooth to prevent further movement. As shown, the rack is straight as used on sliding windows, adjustable ladders and the like, but the rack may be curved or the teeth disposed round a pinion wheel engaging a rack. In this case one arm 6b or 6c may co-operate with pinion teeth and the other with the rack teeth engaged by the pinion, or both arms may co-operate with the pinion. In one arrangement described the pinion has a set of teeth co-operating with the rocking member and another set meshing with a curved hinged rack used as a stay for a hinged fanlight. The device may be modified to control oblique or horizontal sliding movement.

Title: Improvements relating to machines for packing or wrapping powdered or like materials
IPC: B65B1/02
Filed: 1930-05-12
Abstract: 352,157. Packeting-machines. SOUTHALL & SMITH, Ltd. and SOUTHALL, C., Villa Street Works, Hockley, Birmingham. May 12, 1930, No. 14531. [Class 94 (i).] Relates to machines for packing or wrapping small quantities of powdered &c. material in pieces of paper &c., of the type comprising a hopper, means for ejecting the material in the hopper in measured quantities through a nozzle, means for delivering a small sheet of wrapping material beneath the nozzle, a folding die through which the wrapping material is forced by the nozzle while it is receiving the powder &c., and a moving conveyer or table on which the wrapper and its contents are received. The powdered &c. material contained in a fixed main hopper a is fed in a predetermined quantity through a tube b by the intermittent rotation of a screw c, or by the movement of a plunger, to a subsidiary hopper f formed with a nozzle e, the whole being vertically reciprocable by lever and cam mechanism and sliding on slides m between guides n. To prevent the continuous flow of material, the tube b is formed with a closure plate d which supports the superincumbent powder &c., the latter escaping through gaps at the sides. A blank o is fed by any known. mechanism over a die plate K, being pushed through the aperture thereof by the descending nozzle and formed into a packet surrounding the same, the charge being then run in. On the return stroke of the nozzle e, the upper edge of the packet will bear on the underside of the die plate and disengage itself from the nozzle. It then drops on to a moving band l, or a table, from which it is removed by the attendant who twists or folds the open end.

Title: Improvements relating to electric transformers
IPC: G01R19/20
Filed: 1941-11-12
Abstract: 552,815. Current and voltage measurements. BRITISH THOMSON-HOUSTON CO., Ltd., and DYSON, J. Nov. 12, 1941, No. 14580. Addition to 522,671. [Class 37] In a transformer as claimed in the parent Specification, the secondary windings are connected to the A.C. supply through half-wave rectifiers connected in such a way that the peaky negative half-waves pass through them, but the flat-topped positive half-waves are stopped and diverted through the burden so that substantially smooth direct current flows therethrough. Two cores of a material possessing a practically rectangular magnetization curve, each bearing a secondary winding S, Fig. 1, are connected in parallel opposition through half-wave rectifiers a, b to a source of A.C. voltage. The rings also bear primary windings P connected in direct series. These primary windings may consist of a single turn formed by a busbar passing through both rings, or a winding embracing both rings, or separate windings on each ring. The rectified output current may be passed through tertiary windings T, Fig. 7, on each core in such a direction that the ampere-turns oppose those due to the primary winding. Heating due to the high form factor of the current in the secondary windings S is thereby reduced. In a modification, Fig. 8, a second pair of rectifiers c, d, by-passed by a resistance R1, is provided between the secondary windings S and is connected so as to divert peaky negative half-waves through the resistance. The voltage drop caused thereby circulates a unidirectional current round the windings in such a direction that it opposes the primary direct current. Alternatively all the rectifiers may be connected at the same end of the windings as shown in Fig. 9 with the resistance R1 split into two, each half being connected across a half-wave rectifier. If the direction of the primary direct current be reversed, the flat and peaky half-waves will be reversed, the peaky half-waves flowing through the burden and the flat-topped half-waves through the rectifiers. Direction of flow of the primary current may be indicated by passing the rectified current through the primary of a transformer X, Fig. 10, with an airgap in its core, the secondary being connected to a relay W. Normally the rectified output current is smooth and no secondary voltage is induced, but if the primary current is reversed the output current becomes peaky and induces a voltage in the secondary which operates the relay and thereby actuates a signalling device.

Title: Improvements in or relating to the manufacture or treatment of products or articles made of or containing cellulose derivatives
IPC: C08J3/09
Filed: 1931-11-19
Abstract: Filaments, threads, and the like are produced by dry or wet spinning processes from solutions containing cellulose esters or ethers, for example, cellulose acetate of from 52 to 62,5 per cent acetyl content, and methylene ethylene ether.  The methylene ethylene ether may be the sole solvent, or may be present in conjunction with other low, medium, or high boiling solvents and/or diluents.  The solutions may contain other constituents, for example, dyestuffs, pigments, or substances reducing flammability.  In the production of filaments, films, &c. by wet spinning processes, the methylene ethylene ether may be present in the coagulating bath, preferably in high concentration, for example, as in the processes of Specifications 179,234, [Class 2 (ii), Cellulose &c.], 340,324, and 340,325. According to a modification, the methylene ethylene ether is used in the treatment of already formed filaments, threads, films, &c., for example, to diminish the tendency of fabrics to slip, split, or ladder as in Specification 280,990, [Class 2 (ii), Cellulose &c.], to improve the pliability, extension, or knotting properties of filaments or threads, e.g., by shrinking processes as described in Specification 389,823; and to assist in the absorption of various liquid and solid materials by filaments, fabrics, &c., for the purpose of dyeing, printing, discharging, loading, relustring (as in Specification 259,265, [Class 2 (ii), Cellulose &c.]), and delustring.  The methylene ethylene ether may be employed in making up sizes for textiles.  In examples, (1) cellulose acetate fabric is printed with a paste containing dyestuff or pigment, diethylene glycol, water, methylene ethylene ether, and gum arabic; (2) a solution of cellulose acetate in aqueous methylene p  ethylene ether is spun by dry-spinning methods; (3) a solution of cellulose acetate in aqueous methylene ethylene ether is spun into aqueous dioxane; (4) an acetone solution of cellulose acetate is spun into a solution of methylene ethylene ether. Specification 394,016 is also referred to.

Abstract: 457,110. Automatic control systems. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and COATES, H. J., and EMMS, S. A. G., c/o General Electric Co., Ltd., Witton, Birmingham. May 20, 1935, No. 14724. [Class 38 (iv)] [See also Group XL] Registration.-A plurality of members, which are simultaneously moved at speeds normally bearing a definite relation, operate impedances 1 ... 4 associated with electric relays 10, 11, 12, which, when the speed of the members departs from the normal relation, effects an indication or a control corresponding to the incorrect speed. The resistances 1 ... 4 form part of a bridge circuit, and a reversing switch 39 which reverses the polarity of the applied voltage 5, operates together with a device for controlling the direction of movement of the members. Each polarized relay is double acting. For example the relay 10 moves to one of the contacts 24, 25 when the slider 6 lags, and to the other contact when the slider 7 lags. The relays also stop the movement of the members by energizing a trip coil 34. The members may be four wedges, which are moved to and fro on rollers by doubleacting hydraulic rams of the oil-pressure type. Each wedge is operated by an individual ram, and the wedges are in pairs at the opposite ends of a rotating swing bridge and level the ends of the bridge with the roadway.
