Title: Improvements in or relating to aerial systems
Inventor: JOHNSON WILLIAM ARTHUR
IPC: H01Q1/28
Filed: 1948-02-24
Abstract: 655,436. Aerials. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 24, 1948, No. 5434. [Classes 40 (v) and 40 (vii)] An aircraft aerial system comprises a coil coupled to a transmitter and receiver and housed in a channel formed in or on the metal skin of the aircraft, and having an opening which is narrower than the channel itself, whereby the coil is coupled magnetically to the skin of the aircraft which forms a surface-aerial member. In Fig. 5 a toroidal coil 2a is situated within the channel formed by the fairing 4b between the wing 7 and the fuselage. The fairing is formed partly of an insulating material so as to provide a gap 5b. In Figs. 6 and 8, the coil is situated in a channel 4c extending around the leading edge of the wing. Owing to the position of the spar 8, the channel is made external to the wing underneath the wing while it is fully recessed above the wing. The channel is constructed of moulded plastic material and covered, except for a narrow gap, with thin sheet metal. The coil is earthed at its lower end, while the other end is earthed through a variable condenser housed within the fuselage. A tapping is taken off to a receiver within the fuselage through the cable 12. Additional tappings and means to short-circuit out part of the coil may be provided to enable the aerial to operate on a number of wave-bands. In a further modification, the coil extends around the trailing edge of the wing. Fig. 11 illustrates an arrangement comprising a coil set in a recess formed in the leading edge of the wing. The recess is closed by a plastic insulating cover 15e on to which is sprayed metal to leave a narrow insulating gap 5e. The recess is shown as having continuous metallic walls; however, these may be omitted and the openwork structure of spars and stringers within the wing arranged to function as walls for the recess. The arrangement of Fig. 11, which operates on higher frequencies than the other arrangements and covers a wide frequency-band, may be used for either transmission or reception. Specification 607,159 is referred to.

Title: Speedometer or tachometer
IPC: G01P3/20
Filed: 1929-02-21
Abstract: 307,066. Becker, R. E. March 2, 1928, [Convention date]. Centrifugal speed indicators. - A speedometer of the type in which loose balls, thrown outwardly by centrifugal force from the axis of rotation, lift a pressure body to operate an indicator is constructed so that the balls travel outwardly on a curved path and the underside of the pressure body resting on the balls is curved or dish-shaped. In a, tubular part 3 of a bearing frame 1 is disposed a rotating shaft 4, carried by a ball bearing 5 and prevented from being displaced in an axial direction by an adjustable ring 6. Fixed to the upper extremity of the shaft 4 and rotating with it are spherically curved and grooved guides 7 for steel balls 8 which mount in the guides 7 under the action of centrifugal force and which force up the closed box 9 which slides with little friction in the casing 2 and which is prevented from rotating by balls 10 which run in grooves. The box 9 in rising presses against the flexible membrane 13, which is firmly clamped in an air-tight manner between the casing 2 and the lid 12, thus forming an air-tight chamber and which is stiffened by a light helical spring 14 the tension of which can be adjusted by an air-tight regulating screw 15 fitted with a lock nut 16. The pressure m the air-tight chamber is shown by a pressure gauge connected to the air-tight tube 17. Air may be let into or out of the a.ir-tight chamber by means of the valve 18. The shaft 4 is lubricated by an oil chamber 11 with cotton cord. Another form of the invention is shown in Fig. 2 in which the apparatus does not act by means of air pressure but by means of a displaceable pressure pin 19 which is guided on the screw 15 and is pressed upwards by the moving box 9, the upper extremity of the pin mechanically driving an indicator. The pressure of the pin 19, or the air pressure above the membrane 13 can be utilized for operating apparatus for the regulation of fuel in engines or the regulation of steam in steam engines, and when the apparatus is used on cars, the above pressure can operate a sound alarm when the maximum speed is reached.

Title: Improvements in or relating to apparatus for topping-up electric batteries
Inventor: FENNELL CYRIL HENRY
IPC: H01M50/673
Filed: 1950-03-07
Abstract: 682,532. Batteries. CONCORDIA ELECTRIC SAFETY LAMP CO., Ltd. March 7, 1951 [March 7, 1950], No. 5694/50. Class 53. [Also in Group XVII] A device for topping-up accumulators and automatically withdrawing any surplus liquid which may flow into the accumulator and cause it to rise above the required level comprises a trolley 12 carrying pillars 15, 16 supporting a platform 17 on which the batteries to be filled may be placed. One of the pillars, 15, is hollow and forms a storage receptacle for the topping-up liquid and is provided with a delivery tube 37 connected to a flexible pipe 38 which terminates in the filling nozzle, Fig. 4. The receptacle 15 communicates through openings 23 with a pump chamber 20 closed by a flexible diaphragm 25 which can be raised and depressed by a lever 28, Fig. 1, connected by a link 30 to a lever 31 carrying a pedal 33, Fig. 2. When the pedal is depressed the diaphragm 25 moves downwards and liquid is discharged from the receptacle 15 through the tube 37. The nozzle through which the liquid is discharged into the battery consists of a metal tube 45 covered with insulation 46 and carried in an insulating block 43, a metal member 40 and a transparent chamber 48, the parts being held together by a screw 44 and nut 50. The tube 45 communicates through holes 55 with a tube 42 passing through a wood handle 64 and connected to the pipe 38. A metal contact 58 is clamped to the insulation 46 and connected to a conductor 61, a second conductor 62 being connected by a nut 63 to the tube 45. The conductors 61, 62 are clipped at 65 to the pipe 38. When a battery is to be topped up the tube 45 and contact 58 are lowered through the filling opening till the block 43 abuts against the battery cover. Liquid is discharged into the battery so long as the pedal 33 is depressed and when the level of the electrolyte in the battery reaches the lower end of the tube 45 and contact 58 it completes a circuit through the conductors 61, 62 which are connected to a source of current, a relay, and a signalling device such as a bell or buzzer. When the signal is given the operator releases the pedal 33 and the link 30 is pulled downwardly by a spring 34, Fig. 1. The diaphragm 25 is thus forcibly raised and the pressure in the receptacle 15 is reduced. If the liquid in the battery has risen above the lower end of tube 45 the excess liquid is drawn up the tube and through the holes 55 into the tubes 42 and 38 and so passes back into the receptacle 15. The end of the operation can be observed through the transparent chamber 48. The apparatus is shown mounted on a movable trolley. A modification is shown in Figs. 5 and 6 (not shown), in which the apparatus is constructed for attachement to a wall. In this construction the pump chamber is situated at the lower end of the receptacle 15 and the foot lever is attached directly to the diaphragm.
