Title: High frequency electric wave power amplifiers
IPC: H05B6/50
Filed: 1944-07-11
Abstract: 605,315. Valve amplifying circuits. COMMUNICATIONS PATENTS, Ltd., and ROGERS, E. W. July 11, 1944, No. 13252. [Class 40 (vi)] In a power amplifier an indication of the loading of the valve is obtained by comparing the P.D. across a resistor 6, this depending on the anode current, with the P.D. developed across a resistor such as 8, 9, which is dependent on the H.T. voltage. An upper and lower indication level may be obtained with the arrangement shown. When the P.D. across resistor 6 becomes greater than that obtained by the tapping on resistor 9, current flows through the rectifier 13 and operates the relay 12, whose contacts 15 open to extinguish the lamp 18, this being normally fed by a battery 16. If the P.D. rises further to such a point that current flows through relay 10, rectifier 11 and tapping on resistor 8, the relay 10 operates and closes contacts 14 to light lamp 17. Thus, the tappings can be so arranged to indicate when the valve is operating within its optimum limits, by having both lamps extinguished. Instead of lighting indicator lamps the relay contacts may be connected to a reversible motor 19, which may automatically vary the tuning &c. of the load 5 so as to keep it within desired limits.

Filed: 1930-01-29
Abstract: 348,707. Ordnance. IMEX, Ltd. and PAPELLO, K., 29, Martin Lane, Cannon Street, London. Jan. 29, 1930, No. 13292/29. [Class 92 (ii).] Sights and methods of sighting.-Relates to apparatus for continuously sighting a moving aerial or other target and for transmitting the required setting and correcting data to the gun such as the vertical and horizontal deflections for speed and the fuse number. The invention particularly relates to such apparatus wherein the sight 3 is moved in elevation and azimuth by cranks 7, 7<1> to follow the target, and wherein cams 51, 52 for time of flight, cam 83 for tangent elevation, and cam 98 for fuze number, are simultaneously rotated by a shaft 55 after a preliminary endwise combined adjustment of such cams by a gear 56 to suit the height of the target. According to the invention, additional cams 63 for vertical and horizontal deflection are employed, and reversible electric motors 26 are used to cause the sight to follow the target automatically after the sight has been directed on the target by hand. Considering first the sight elevating-mechanism on the left of the Figure which is duplicated on the right for training. Electric contacts 24, 25 cause the motor 26 to operate in one direction or the other according to the setting of a roller 21 with reference to a uniformly rotating friction disc 23 effected by engaging a clutch 10 with the hand-gear 7, the clutch being disconnected when the motor takes up the drive of the sight through the shaft 32 and differential gear 5. The setting of the roller 21 through a screw gear 19 on shaft 17 is a measure of the angular velocity of the target in elevation and this is conveyed to a screw gear 40 for inclining a lever 80 in accordance with the angular acceleration. One end of the lever carries a roller riding on a uniformly rotating drum 44 the other end engaging between electric contacts 78, 79. A rod 53, moved horizontally by one of two rods 60, 61 engaging alternative time cams 51, 52, and vertically by the deflection snailcam 63, carries the electric contacts 78, 79 which control a reversible motor 76 for rotating the deflection cam through a worm gear 73 the worm of which receives a correcting movement for tangent elevation through cam 83 and bell-crank lever 85. The resultant corrections in elevation are conveyed through a shaft 94 and differential gear 89 to the elevation transmitter 112. Similar apparatus actuates the training transmitter 111. The fuse number is obtained from the cam 98 bv known mechanism including a reversible motor 105 for actuating a transmitter 107. In place of the reversible motors 26, 76, 105, hand actuation is provided for by cranks 33, 70, 110 respectively. The cams are constructed so that they provide a larger scale for the smaller heights of the target and the smaller angles of gun elevation and a logarithmic time cam 52 is provided as an alternative to the time cam 51.

Title: Improvements in or relating to rivets
IPC: F16B19/12
Filed: 1943-08-17
Abstract: 567,666. Rivets. JAKOSKY, J. J. Aug. 17, 1943, No. 13389. [Class 89 (i)] Relates to rivets of the kind described in Specifications 567,664 and 567,665, [Group XXII], and consists in providing within the. rivet a rigid member that fills the greater part of the cavity and is adapted to resist shear. A solid pin 22 is introduced into the rivet 10 prior to forging the head to form the restricted opening 14. The rivet has a slight clearance 30 in the hole in the plates 15, 16 and has thinner walls than in the previous forms, thus reducing the pressure required to effect expansion. As the rivet expands to fill the holes and join the bulbous head sufficient clearance develops between the pin 22 and the walls of the rivet to allow the setting fluid to pass. This fluid is self-hardening, such as a lacquer or thermoplastic material. In modifications, the rivet is a tight fit in the hole and the pin is a tight fit in the rivet, being provided with flutes or a central bore to pass the setting liquid. In a further modification the bore of the rivet is uniform throughout the preformed head and the pin is retained by the setting fluid. Where the rivet is subject to electrolytic corrosion the pin should have an electric potential equal to that of the rivet or should be formed of inert material.

Title: Improvements in the pulping of fibrous cellulosic material
IPC: D21C3/18
Filed: 1943-08-18
Abstract: Hemp, jute, seed flax straw and other bast fibre materials are subjected to the action of an acid aqueous solution of an inorganic chlorite, e.g. an acidified solution of sodium or calcium chlorite, in order to obtain a pulp suitable for the production of paper, e.g. bank-note paper, condenser tissue, carbon paper, electrical-insulating paper, or sand-paper.  Bast fibre materials containing large amounts of shive or pith may be treated.  The chlorite may be used in a concentration of 8-10 per cent based on the dry weight of the stock, and the pH value may be adjusted to 1.5-4.5 by the addition of acetic, hydrochloric, or other acid.  The treatment may be carried out at elevated temperature.  Prior to the treatment with chlorite, the cellulose material may be treated with caustic soda, sodium carbonate, chlorine, hypochlorite, or a mixture of caustic soda and sodium sulphide.  In an example, hemp fibre is immersed in a warm solution of 20 per cent nitric acid for an hour. The liquid is decanted and the fibre is allowed to rest for several hours.  It is then washed and boiled for an hour in dilute sodium carbonate solution.  The material is washed and then treated for several hours with a hot acid solution of calcium chlorite.  The treated material is washed and milled to form a pulp of good quality free from shives.  In other examples, the hemp or flax straw is pretreated with water, sodium carbonate solution, caustic soda solution, a mixture of caustic soda and sodium sulphide, chlorine, or hypochlorite.  The treatment with chlorite may be effected at boiling temperature.  The acidity may be adjusted at intervals during the treatment by the addition of acid.
