Patent GB-289267-A (GB)
Title: Improvements in apparatus relating to aerial observation or navigation
IPC: F41G9/02
Filed: 1923-07-28
Abstract: 289,267. Bygrave, L. C. July 28, 1923. Teaching aviators.-Instruction apparatus for air pilots and bombers comprises opticalprojection apparatus 11, Fig. 1, which throws a map-picture on a ground-screen 10 and moves it to simulate the effect of straight flying, drift, turning, &c. to an observer looking through a sight 14. Movement of a rudder-bar causes the projection-plate 18 to turn round an axis 16 eccentric to the optical axis so that the groundpicture turns round a point T below the sight. The plate 18 can be traversed along two axes at right angles, a motion corresponding to windspeed being given along one axis and air-speed being resolved along both axes, the resolution being varied automatically as the plate turns. If a course-setting bomb-sight is used, the needle is turned in synchronism with the plate by means of a permanent magnet. The closing of a " bomb-release " switch stops the plate after a delay representing the time of fall of the bomb, and the bomber's error is then represented by the distance on the ground-screen between the trail-point T and the target. The projector may be arranged to imitate the effects of banking, pitching, rolling and yawing. The plate 18 is carried by a rectangular frame 20, Fig. 6, having racks on its four sides engaged by long pinions (one shown at 23) mounted at right angles on a rotatable frame 9. This frame is turned, through gearing 44, 43, by a reversible motor 42 governed by the rudder bar 15, Fig. 9. The pinion 23 is geared to a square shaft driven from a disc 29 by a friction-wheel 28, which is carried by a frame 31 and can be given an initial radial adjustment (corresponding to wind-speed) along the disc 29 by a setting-shaft 32. As the frame 9 rotates, this adjustment is varied by radial movement of the frame 31, which has a pin 34 engaging a camgroove in the fixed casing 11. The disc 29 and a similar disc for driving the other long pinion through similar gearing are driven at constant speed by a second motor 40, Fig. 9. Closure of the bomb-release switch 53 energizes a magnet 54 to release a friction-driven wheel 56 which, after an interval, opens the main circuit at 60 ; on release of the switch 53 the circuit is re-closed at 61.
Patent GB-1222585-A (GB)
Title: Improved code generator
IPC: H03M7/14
Filed: 1968-04-24
Abstract: 1,222,585. Morse code generators. GENERAL PRECISION SYSTEMS Inc. 24 April, 1968 [24 April, 1967], No. 19503/68. Heading G4H. A system for repetitively generating Morse Code comprises a clock generator 21 producing pulses at a prescribed rate, a counter, 31-34 driven by the pulses, gates 35 connected to the outputs of the counter stages to provide a repeated sequence of time-spaced pulses on a number of outputs 1-13, means 23 for combining these outputs in combinations of one or more pulse lengths to form code pulses of varying length to represent the described information. The clock generator 21 produces pulses at 10 c/s. which are applied to the first stage 31 of the counter. The outputs of the four stages of the counter are combined in 13 groups representing counts 0-12 by gates in block 35 (Fig. 2, not shown) the pulse on each lead in turn being one tenth of a second in duration, with no interval between pulses. In the Morse code the dots are one pulse long and the dashes are three pulses long. The pulses of a letter group are separated by intervals of one pulse length and letters are separated by three pulse lengths. In block 23 the pulses on the leads 1-13 are combined in NOR gates to form 26 sequences of dots and dashes representing the alphabet. These are applied each on a separate lead to three selector switches (Fig. 4, not shown) which are manually set to select the required letters to be sent. In addition a direct connection may be made to one of the letter leads, e.g. the lead " I ". The selected letters on leads 14, 15, 16 and the " I "lead are applied to four gates which are opened in turn by a counter (Fig. 5, not shown) so that the selected letters are transmitted in sequence. Since some morse code letters are shorter than others (E is one pulse long and 0 is eleven pulses long) means are provided for resetting counter 31-34 at the end of a letter, and, after a pause of three pulses, to start the next cycle. Switches may be provided in selector 26 (Fig. 6, not shown) for changing the mode of operation. The apparatus may be used for repetitively generating code identifications of radio transmitters used in an aircraft navigational system.

Title: Improvements in and relating to methods of rendering materials waterproof or water-repellent
IPC: D06M15/643
Filed: 1943-11-25
Abstract: Oily products, useful for waterproofing, are obtained by hydrolysing a compound having the formula CH3SiHX2, where X is a halogen atom such as chlorine or bromine, by pouring an ether solution of the compound into a mixture of ice and water. The product is washed with water to remove the acid products of hydrolysis and dissolved in toluene, carbon tetrachloride, benzene, ether, or liquid aliphatic hydrocarbons.  Accelerated ageing and improved water-repellence are obtained by adding catalysts such as lead, zinc, or iron resinate or naphthenate, lead nitrate, or a hydrolysable borate such as ethyl borate.

Patent GB-666199-A (GB)
Title: Improvements in or relating to the manufacture of threads and fibres from molten polymeric organic compounds
IPC: D01D4/02
Filed: 1949-07-27
Abstract: Artificial filaments, fibres, or threads, are obtained by extruding a molten polymeric organic compound through metal spinnerets which have been coated with a thin film of a thermo-resistant organic compound of silicon.  The coating prevents the formation of deposits of the filament-forming compound on the surface of the spinnerets.  The silicon compound may be a polyorganosiloxane or a polysilazine.  It may be a poly-methylsiloxane, a cyclic siloxane such as a poly-octamethyl-cyclotetrasiloxane, or a reaction product of an organo-siliconhalide with water-free ammonia.  In an example, a molten polyamide obtained from hexamethylene diamine and adipic acid is extruded through a chrome-nickel-steel spinneret which has previously been exposed to the vapour of dimethyl-dichloro-silane. In another example, a molten polycaproicamide is extruded through a chrome-nickel-steel spinneret which has previously been coated by immersion in a benzene solution of a reaction product of dimethyl-dichloro-silane and water-free ammonia.  The treated spinnerets may be used in the melt-spinning of polyamides, polyesters, polyesteramides, and polyurethanes including condensation products of glycols with di-isocyanates. Specifications 572,740, [Group VIII], 593,727 and 625,748, are referred to.
