The batt may include as high-shrinkage-force fibres polypropylene fibres which are at least partially drawn, together with natural fibres or polyesters, polyamides or other synthetic fibres exhibiting low shrinkage at the treatment temperature envisaged and may further be treated with resinous or elastomeric bonding or filling agents before being coated as above. Specifications 787,900, 908,613 and 993,472 are referred to.ALSO:A process for the production of fibrous non-woven sheet materials comprises forming and then subjecting to a shrinkage treatment a batt of fibres which contains 20 to 50% by weight of fibres which have the property of shrinking by at least 10% of their original length when under a load of 0.005 grams per denier at 150 DEG C.  The fibres preferably are not embrittled by such heat treatment.  Suitable fibres are those of polypropylene which are at least partially drawn.  The batt may be needled to provide initial consolidation, then heated, e.g. by pressurised steam, to about 150 DEG C. to cause shrinkage of the fibres and thereby to consolidate the web further.  The batt may be impregnated with a resinous or elastomeric filling compound before or after shrinkage e.g. a butadiene-acrylonitrile copolymer may be applied to the impregnated batt which is then squeezed, dried and heated under pressure to provide a leather-like sheet.  Coagulation or curing of the filling compound may be effected simultaneously with shrinking of the batt. Other fibres which may be present in the batt include natural fibres or polyesters, polyamides or other synthetic fibres which exhibit low shrinkage at the treatment temperature envisaged.  The fabric may be further coated on one or both sides, patterned to resemble leather or further treated to simulate suede.  Known bonding or filling agents referred to include natural latex emulsions, polyester-urethanes, polyether-urethanes, copolymers of acrylonitrile with butadiene or certain acrylate esters, neoprene rubbers, rubbery polymers and copolymers derived from butadiene or isoprene, and plasticised polyvinyl chloride.

Title: An improved process for the manufacture of photo-electric cells
IPC: H01J40/06
Filed: 1921-03-23
Abstract: 178,300. Case, T. W. March 23, 1921. Vacuum tubes. - A method of producing an electronemitting cathode, such as the lightsensitive cathode of a photo-electric cell consists in depositing a layer of material on an element which forms part of the cathode, by means of a discharge, for which the element forms the anode, while another electrode, such as an incandescent filament, comprising the material to be deposited, forms the cathode. A filament is coated with the oxide of a metal, such as an alkaline earth metal, or superposed coatings of different oxides may be used. The corresponding nitrates may be deposited on the filament and reduced to oxides by heating the filament. Sodium and potassium may also be used in the coating. The coated filament 1 and a metal electrode 2 are mounted in a bulb which is exhausted of air and baked. The metal electrode is heated to redness to drive off remaining gases, by means of a discharge between the filament, heated by a battery 3, and the electrode 2 acting as an anode, for instance by connecting the electrode and the filament with the secondary of a transformer 4. The temperature of the electrode 2 is then reduced by regulating the potential, and the filament temperature is adjusted so that the discharge causes metal or metals to be emitted from the oxide coating and to be deposited as a layer on the electrode 2. The tube is connected with a pump so as to maintain the vacuum. The deposition process is stopped at intervals and the photoelectric qualities of the tube are tested. The electrode 2 forms the cathode in the completed cell, and the filament is used as an unheated electrode. An inert gas such as argon or helium mav be admitted to the tube to increase the conductivity.

Title: Electric alarm apparatus
Inventor: STEVENS JAMES REGINALD HERBERT
IPC: G08B13/22
Filed: 1960-03-15
Abstract: 911,925. Burglar and like alarms. ERICSSON TELEPHONES Ltd. March 1, 1961 [March 15, 1960], No. 9049/60. Class 118. In an electric alarm system the release of a normally operated relay A (Fig. 3), consequent upon the opening of detector contacts 10, 11, brings up the alarm relay AL (Fig. 1), which connects up one or more audible alarms (Fig. 4, not shown), and also energizes a thermal relay TH (Fig. 1), as a result of which the alarm relay AL is subsequently released to mute the audible alarms. The apparatus is brought into service by the manual operation of switch Z1 or Z2 (Fig. 2), which may be at different locations. Relay S pulls up and locks, and is followed by D and DA (Fig. 1), A (Fig. 3), F (Fig. 2), and DX (Fig. 1). The lamps 20, 21 (Fig. 2) are thus lit, and relay S is released. If the detector circuit is complete, A remains up and D is released followed by DA, thus extinguishing the lamps 20, 21. If the detector circuit is not complete, D holds up and the lamps remain lit. Assuming the detector circuit is complete, A, DX and F remain held. Breaking of the detector circuit releases A, whereupon AL pulls up and the audible alarms sound. Relay TH is energized during the release time of DX and upon operation removes a short circuit from DY which pulls up, locks, and brings up CK. The subsequent release of TH brings down DY which lights the lamps 20, 21 and short-circuits AL to mute the audible alarms. The apparatus remains in this condition with F and CK held until either Z1 or Z2 is operated. Specification 911,926 is referred to.

Abstract: 177,788. Flettner, A. March 30, 1921, [Convention date]. Steering-gear.-Relates to the steering gears for marine and aerial vessels of the kind in which positive actuation of an auxiliary rudder causes the main rudder to be moved by pressure of the fluid in which the craft is moving, and consists in providing a gear which, whilst uniformly actuated, moves the auxiliary rudder at different predetermined rates, and also in connecting the casing containing the gear with the main rudder so that when it swings under the action of the current, and particularly on the ship reversing, the auxiliary rudder also swings relatively thereto in a definite manner. The main gearing includes an interposed or auxiliary gear which provides for a quick or large movement of the auxiliary rudder for initial small movements of the main rudder. As shown in Fig. 2, the steering shaft x drives through gearing c, d and connecting-rod f a rack g which in turn actuates through a pinion crank h and connecting-rod i the auxiliary rudder b. In this case, the uniform motion of the shaft x results in a simple harmonic motion of the shaft y of the auxiliary rudder. In a modification wherein the shaft y remains stationary during the middle portion of the period when the main rudder swings through 180‹ on reversing, the main gearing comprises a worm drive R, s for the shaft x, Figs. 7 and 8, which is mounted above a casing containing the interposed gear, this casing being keyed to the hollow spindle H of the main rudder. The drive passes from the shaft x to the shaft y of the auxiliary rudder through spur wheels c, d, connecting rod f, crank lever p, through springs r, g to a quadrant k, thence to pinion l, and finally through rods n, o.
