Patent GB-316921-A (GB)
Abstract: 316,921. Wellington, R. N. May 5, 1928. Grounding aerials ; undesired signals, climinating; receiving-sets, construction of.-An accessory unit for wireless receiving apparatus comprises a lead-in tube and earthing-switch structurally combined with a condenser, the capacity of which is varied as the switch is operated. The unit may also carry coils which in association with the condenser act as an adjustable wavetrap for undesired waves, or as the tuning-circuit of a crystal receiver. Figs. 1 and 2 show the lead-in and switch, and Fig. 3 the removable coils. The insulating lead-in tube F carries a terminal A at one end for the attachment of the aerial, and an insulating-plate I at the other end for securing it in position. The terminal A makes contact through a spring B with a pistonblock C slidable in the bore of the tube I and normally pressed into contact with earthed radial pins E, or an internal ring. To bring the set into use, an axial screwed rod G is advanced by rotating the knob L until its pointed end engages the block C, and removes it from the earthed contacts E. The rod G is threaded in a nut H, which is in conductive connection with a socket P and a screw terminal O, Fig. 2. The rod G carries a conductive plate K which is associated with a fixed plate J to form a variable capacity. The plate J is connected to a socket Q and to a screw terminal N. The condenser J, K forms a variable series capacity between the aerial and the receiving-set, the plate J being connected to the aerial terminal of the set. This series capacity is increased in value as the rod G is screwed in, and eventually is short-circuited by contact of the plates J, K. To employ the device as a wave trap for undesired signals, it is shunted by a coil or coils plugged into the sockets P, Q and the condenser is adjusted to tune the rejector circuit thus formed. When using the device as a crystal receiver, the coil is plugged in the sockets P, Q. and a crystal detector in series with head-phones is connected across the terminals O, N, the latter of which is earthed. A suitable tapped coil is shown in Fig. 3, comprising a longwave coil 4 wound on a cruciform frame and connected in series with a short-wave coil 2 wound round pins 3. The axes of the coils are at right angles. Their extreme ends are taken to plugs 7, 8 for insertion in the sockets P, Q, Fig. 2, whilst intermediate taps are taken to sockets 9, any one of which may be selected by a loose plug 6 so as to short-circuit more or less of the turns.

Title: Production of ketoximes
Filed: 1962-08-20
Abstract: Ketoximes are made by reacting a normally liquid cyclic paraffinic compound with a mixture of nitrosyl chloride and hydrogen chloride, to give the ketoxime directly in the form of its hydrochloride, while irradiating with light which has been passed through a filter which cuts out substantially all light of wavelengths less than 2800 <\>pA. The preferred light source is a mercury vapour lamp, but electric arcs, incandescent lamps and sunlight may also be used.  Liquid or solid filters may be employed, e.g. certain types of glass, aqueous salt solutions or an organic liquid.  When a solid filter is used it may comprise part or all of a wall of the reaction zone, e.g. a mercury vapour lamp immersed in a coolant liquid contained in a glass vessel inside the reaction zone.  Suitable paraffins are those containing 5-20-membered rings.  An inert solvent may be used. The examples relate to the preparation of cyclohexanone oxime. Specification 788,436 is referred to.

Title: Improvements in or relating to anti-negative g valve mechanism for respiratory appliances
Inventor: WILKENING WALTER OTTO
IPC: A62B7/14
Filed: 1955-11-08
Abstract: 788,339. Respiratory appliances. ARO EQUIPMENT CORPORATION. Nov. 8, 1955, No. 31910/55. Class 81 (2). A respiratory control unit, for use in aircraft, has means which, when subjected to an upward acceleration, interrupts the oxygen supply and admits air at relatively high pressure to the breathing mask. Oxygen, at normal breathing pressure, is supplied through a pipe 110e and non-return valve 34 to a chamber 20 from which it passes through a port in a diaphragm 14a to a space 16, connected by pipe 110c to the breathing mask. When the aircraft is manoeuvred in such a way that the body is subjected to an upward acceleration a weight 28, attached to diaphragm 14a, lifts the diaphragm to close the port against a seating 24b, thereby cutting off the oxygen supply, and continues thereafter to lift the rod 24 against spring 24e, and open a valve 24h. The latter valve allows high pressure air, admitted through pipe 110d by pressure regulator 22, to pass into chamber 16 and thence to the user. When the acceleration is discontinued, the diaphragm 14a is returned to its lower position and the valve 24h is closed, the excess air pressure in the space 16 and the face mask passing in the reverse direction through the port in the diaphragm and escaping to atmosphere through a balanced valve 30. An adjustable spring-loaded valve 36 prevents the air pressure in the chamber 16 from reaching excessive values.

Patent GB-825511-A (GB)
Title: Improvements in or relating to moulded or cast products, and the making of moulds therefor
Inventor: DAVIS FREDERICK LEWIS
IPC: B29C41/14
Filed: 1956-10-24
Abstract: A mould is produced by forming a thin flexible envelope having the shape of the mould cavity, filling the envelope with an easily removable material, coating the filled envelope with an electrically conductive lacquer, and electroplating the coated envelope with metal to form the mould, the filling material and envelope being then removed.  The metal mould may be of nickel or chromium alone or backed by electroplating with copper. Preferably the flexible envelope is produced by dipping a master former into rubber latex, chemically roughening the latex coating and then vulcanizing it, dipping the coated former in rubber latex, vulcanising the second coating, stripping the second coating from the coated former, and turning it inside out.  The metal mould is used to make formers for dipping as by casting into the mould a vinyl plastic of sufficient flexibility and elasticity to allow its removal on setting with the aid of an anchor member secured in the former during casting, removal preferably being effected while the former is still warm.  If desired the vinyl plastic forms only a shell as by use of slush moulding or rotational casting techniques, the shell after removal from the mould being filled with a cheaper material.  As described the invention is applied to formers for making rubber gloves with roughened surfaces by dipping and the removable filling for the envelope (of glove shape) is wax.

Title: Improvements in and relating to laundry folding machinery
IPC: D06F89/00
Filed: 1947-12-09
Abstract: 651,340. Folding fabrics. MANLOVE, ALLIOTT & CO., Ltd., BOAM, H., and SIBERT, V. S. Dec. 9, 1947, No. 32467. [Class 42 (ii)] A machine for folding laundered articles comprises a conveyer 14 for the articles, an electric switch 38 controlled by operating means arranged in the path of the article so as to be closed by the leading edge of the article and opened by the trailing edge, arresting means 44 which are situated ahead of the switch-operating means and which, in response to the closing of the switch, lift the leading edge and maintain it lifted and, in response to the opening of the switch, release the leading edge, and means for delaying the responses of the arresting means to the closing and opening of the switch for an interval of time substantially equal to that taken by the article to move from the switch operating means to the arresting means. As shown, conveyer 14 comprises a number of endless tapes 18 spaced apart and supported along their upper run on a plate 22. An article 34 from an ironing-machine 10 passes beneath a nipping device 24 comprising tapes 28 lying above tapes 18 and similarly spaced apart. Levers 32 fixed to a rotatable bar 30 and normally projecting between tapes 18 and 28 are depressed by the leading edge of the article to close switch 38. The arresting means 44 consists of a series of clips depending into the spaces between tapes 18; each clip has jaws 47, 48 controlled by a solenoid 54, and the clips can be swung up about a shaft 46 by the action of a solenoid 66. The closing of switch 38 operates time-delay relays 40, 42 set to energize solenoids 54, 56 as the leading edge of the article reaches the clips 44 so that the leading edge is gripped between jaws 47, 48 and raised while the trailing part of the article is fed forward. As the trailing edge of the article passes levers 32, switch 38 opens and de-energizes solenoids 54, 56 after time delays of the same magnitude as those imposed on the closing of the switch; jaws 47, 48 are thus opened to release the leading edge of the article so that it drops close to the trailing edge, as at 34A, and clips 44 thereafter drop back to their original position. The folded edge of the article is ironed in a nipping device 24a associated with a second folding apparatus, similar to the first, which folds the article 34A a second time, as at 34B. The folded articles may be discharged on to a conveyer running transversely to conveyer 14, whereon they are folded at right-angles to the first folds. The machine may be adapted to deal with two side-by-side lanes of articles from the ironing machine by duplicating the folding and control mechanisms at the two sides of the conveyor 14. The switches, instead of being mechanically controlled, may be controlled by light-sensitive cells, the intensity of incident light on which is varied by the passage of the article. Specification 618,157 is referred to.
