Title: Improvements in apparatus for facilitating blind flying
IPC: B64D45/00
Filed: 1935-06-21
Abstract: 458,812. Apparatus for facilitating blind flying. FLOREZ, L. DE, 19, Rector Street, New York, U.S.A. June 21, 1935, No. 17893. Convention date, July 5, 1934. [Class 4] Apparatus for facilitating blind flying comprises binaural signal receivers, means for generating a signal for these receivers, and means responsive to changes from a normal flight attitude for selectively directing the signal to the receivers. As shown a gyroscopic turn indicator 7 is adapted to produce signals in one or other of headphones 5, 6 on deviation of the craft from a straight course. Arm 8 of the indicator as it swings from its neutral position engages one or other of variable resistance elements 9, 10 in each instance gradually cutting out resistance as deflection increases. The outer ends of resistances 9, 10 are connected by wires 11, 12 with left and right headphones 5, 6, respectively. The signal source consists of a winddriven generator 13 mounted on a wing clear of the airscrew slip stream. The generator is connected by wire 14 to arm 8 and by wire 15 to a point 16 intermediate of the headphones. If a turn is initiated the pilot thus receives a signal in one headphone, the strength of the signal being dependent on the rate of turn. In a modified form the pilot receives an equal signal in both ears whilst the aircraft continues on a straight course and is apprised of a turn by the cessation of the signal in one headphone. An indication of whether the craft is diving or climbing is conveyed to the pilot by the change of signal note received as the generator is speeded up or slowed down. Provision may be made in the arrangement of Fig. 1 for the pilot to receive a low signal even when the craft is on its course ; this is effected by bridging resistances 9, 10 by a relatively high resistance 18. Lateral tilting is indicated to the pilot by modulating the turn or pitch signals or by superimposing a distinguishable signal. As shown a pendulum bank indicator arm 19 provided with a damping device 31, is pivoted to swing into engagement with one or other resistance 20, 21 connected by wiring 22, 11 and 23, 12 with left and right headphones respectively, and thus to produce a series of clicks varying in intensity with the degree of bank. Abnormal banking causes engagement of arm 19 with one or other of contact segments 24, 25 connected on to telephone line 15 by wiring 26 including a battery or the like 27 in parallel with a current interrupter 28. The headphones 5, 6 may be connected through switch 34 with a radio receiving set. The generator 13 may be substituted by means for receiving a radio signal from the ground which is selectively directed to the headphones in accordance with changes in flight attitude.

Abstract: 681,046. Packeting-machines. ESSELTE FORPACKING AKTIEBOLAG. July 18, 1950, No. 17911/50. Class 94 (i)  In a packeting-machine, collapsed cartons a are fed from a magazine i by a reciprocating member k which is formed with an abutment o which moves each carton to an intermediate position and a spring-loaded tooth p (see Fig. 4, not shown) which moves it from the intermediate position into one of a series of rectangular pockets h in an intermittently-rotated carrier g. The carton is positioned obliquely in the recess and is temporarily held therein by a spring-loaded finger 2 pivoted to a bracket q so that on movement of the carrier to position a<SP>1</SP> it passes beneath a segmental guide 4. At position a<SP>1</SP> its leading edge is engaged by a serrated roller 9 mounted on a lever 6 which is pivoted in the guide 4 and adjustable by a screw 7 against the action of a spring 8 whereby the next movement of the carrier causes the carton to be erected and pressed into the recess. The action of the roller is assisted by a blade spring 12. As the carton is moved to the intermediate position, fingers w pivoted to adjustable guide bars u on the bracket q pass beneath the end flaps b of the carton, whereby on the subsequent movement of the carton into the recess, the guide bars bend the flaps through a right angle into the position shown. The guide 4 is fitted with segmental side plates 5 forming channels in which the flaps are guided as the carton is moved with the carrier.

An electroluminescent lamp comprises a pair of spaced conductive electrodes side by side on an insulating support with the electroluminescent material disposed between them. In Fig. 1 (not shown), the conductors form a two-start helix on a glass rod and the conductors may have a coating of insulating varnish. In Fig. 2 two wires 11, 12 coated with insulation 18 are mounted on a flat plate 19 with fine-powdered luminescent material 15 over and between the wires. In Fig. 3 the electrodes are intermeshed grids 16, 17 printed on an insulating plate or deposited by sputtering or electrodeposition. A layer of dielectric is formed thereover, followed by the phosphor layer 15. The spacing of the wires is a few thousandths of an inch, and dielectric material may be mixed with the phosphor to prevent flash-over. Nitrocellulose, polyvinyl chloride or polyethylacrylate may be mixedwith the phosphor and applied in layers 0.005 inch thick. The phosphors may be zinc oxide alone or zinc sulphide containing 25 per cent zinc oxide and 0.001-1 per cent of halide, e.g. chloride or bromide added as acid, ammonium, zinc, cadmium, alkali or organic halides, with activators copper 0.00001-0.005 per cent, and lead 0.1-5 per cent introduced as sulphates. Cadmium compounds may be combined with the zinc oxide and zinc sulphide phosphors. Suitable organic phosphors are petroleum jelly, anthracene or phenanthrene and they should be in intimate contact with the conductors.

Abstract: 1,208,959. Electro-plating fibres. ROLLSROYCE Ltd. July 14, 1969 [April 17, 1968], No.18256/68. Heading C7B. Individual conductive fibres, e.g. of carbon or graphite, in a tour or tape are electro -plated with a metal or an alloy e.g. Ni by passing the tow or tape as cathode through a plating (e.g. nickel sulphamate) bath containing an anode and directing at least one jet of electrolyte at the tow or tape within the bath to force electrolyte to circulate between the individual fibres of the tow or tape. Current may be supplied to the tow or tape at a point prior to its entry into the bath and at a point after its emergence from the bath, the magnitude of the current supplied at the latter point being the greater. The tow or tape may be wetted and passed over a shaped guide prior to its entry into the bath, being continuously wound through the bath by at least one driven drum. The electrolyte is preferably continuously filtered. The plated fibres may be compacted, e.g. by electro-forming or hotpressing, to form a composite material.

[Also in Group I] The press (for separating liquids from solids) shown may be used for the separation of the liquid content from pulpy material such as crushed grapes by fermentation, with or without prior extraction of liquid by compression (see Group I). The container is closed in a pressure or air-tight manner. The contained pulp is then allowed to ferment and the gas thereby generated rises upwardly, carrying with it the suspended solids and permitting the purer liquid to accumulate at the bottom of the chamber. After the liquid has been drained off the solids remaining may be treated with a leaching liquid such as a lowquality wine, spent wash or water. Several presses and a reservoir tank for the leaching liquid may be arranged in series and the leaching liquid pumped therethrough in a closed circuit (Fig. 2, not shown). The presses may be connected in parallel instead of in series; the direction of flow of the leaching liquid may be reversed.

Abstract: 164,627. Unione Italiana fra Consumatori e Fabbricani di Concimi e Prodotti Chemici, and Sonneck, A. July 5, 1920. Sulphuric acid chambers are constructed so that their height is great compared with their horizontal cross-section, and they are connected by means of junction pipes only at their lower ends. To avoid the possibility of the gases passing directly through the chamber without rising to the upper part, the inlet is placed a little higher than the outlet, as shown. The chambers may be any shape provided they are tall, and they may be connected in series or in parallel. In their passage through the chamber A, the gases come in contact with the water from the sprinklers S and with the condensed acid in the vessels B.
