Title: Improvements in or relating to radio beacons
IPC: G01S1/02
Filed: 1944-01-28
Abstract: 581,576. Radio direction-finding. BUTEMENT, W. A. S., and BEDFORD, L. H. Jan. 28, 1944, No. 1684. [Class 40 (v)] In a radio-beacon system in which a field of the equi-signal overlapping-beam type is continuously rotated, the alternate switching of the beam is effected at an audio-frequency producing at a receiver a tone signal which disappears when the receiver is on the equisignal line, the disappearance of the tone permitting an indication of the orientation of the equi-signal line at that instant to be received. As shown, the orientation indications are given by modulating the transmission with a speech record 4, driven by the motor 3 in synchronism with the aerial system 2, the record comprising the numbers 0 to 90, 0 to 180, or 0 to 360. To give indications up to 180 degrees the numbers 0 to 90 may be recorded twice in male and female voices. The aerial system comprises two dipoles 5 arranged symmetrically in an angular reflector 6 and connected to the transmitter 1 through a forked coaxial line 7. Each-branch contains a short-circuited stub 8 at a quarter-wave distance from the junction, the stubs containing diodes 9 which are rendered operative alter- - nately by a 1500 c.p.s. supply 11. Gaps 10 in the outer conductors of the stubs permit biassing voltages to be applied to the diodes. Alternatively, the stubs with diodes may be replaced by variable capacities formed by rotating a disc of dielectric material between stationary electrodes, the disc being slotted or carrying conducting segments so that the capacities of the branches are oscillated alternately between maximum and minimum values. Since the second harmonic of the tone signal will not disappear on the equi-signal line, the co-operating receiver should have a cut-off slightly below this second harmonic frequency.

Title: Improvements in or relating to test pick-up devices for use in connection with aircraft and other screened internal-combustion ignition systems
IPC: F02P17/12
Filed: 1948-01-20
Abstract: 635,803. Testing ignition. MARCONI'S WIRELESS. TELEGRAPH CO., Ltd., and STEVENS, J. W. SANGER-. Jan. 20, 1948, No. 1762. [Class 7 (iv)] In a tester pick-up arrangement for an aircraft or other screened internal - combustion engine, comprising a pick-up device 4 in the form of a metal sleeve 4a, wholly or partly sheathed in rubber or other suitable insulating material 4b and having means, such as a boss 4c, for making connections thereto, the sheathed sleeve is adapted to pass an ignition lead so that the metal sleeve 4a thereof is electrostatically coupled to the conductor in the ignition lead, the pick-up device 4 is adapted to fit between a nipple 7 or like member on the harness member 6 of the screening system and a ferrule 1b adapted to receive a flexible conduit member 5 of the screening system, and clamping means 2 are adapted to clamp together the ferrule 1b, the pick-up device 4 and the nipple 7 as a mechanically rigid structure out of which the connection means 4c project. The pick-up device 4 may be positioned in the clamping means 2 in either the normal or inverted position, and a waterproof rubber-like sheath may cover the flexible conduit 5 as well as the joint between the conduit and the ferrule 1b. The pick-up is used in connection with an oscillograph ignition tester.

Title: Improvements in or relating to ultra high frequency electron discharge apparatus
IPC: H01J25/30
Filed: 1944-01-31
Abstract: 588,293. Velocity modulated tubes. SPERRY GYROSCOPE CO., Inc. Jan. 31, 1944, No. 1819. Convention date, Feb. 9, 1943. [Class 39 (i)] In a reflex oscillator the input and output gaps are separate and have different spacings ; preferably, but not essentially, the output gap is made narrower than the input gap. This enables the effective voltage at the output gap to be made higher than that at the input gap, with a resulting increase in efticiency. In. the form shown, the beam from cathode 21, focused by shield 22, passes through resonator 11 by way of grids 14, 17, forming the input gap. The modulated beam is reflected by electrode 25 to pass again through the resonator by way of grids 16, 14 forming the narrower output gap. After delivering energy to the resonator, the beam falls on collector 23. Many modifications of this form are described, some of which are generated by rotating its cross-section about various axes or by translating it longitudinally. The grids may be mesh, or rods of different lengths projecting radially inwards. The refiector may be dished or curved or may be replaced by a magnetic deflecting system, Fig. 12 (not shown). The collector electrode may be an extension of the cathode or part of the resonator wall, and may be provided with cooling coils, Fig. 16 (not shown). Tuning means for the cavity resonator are provided. Specifications 523,712 and 535,767 are referred to.

Abstract: 1,161,041. Cartridge-actuated tools. OLIN MATHIESON CHEMICAL CORP. 13 Jan., 1967 [20 Jan., 1966], No. 1998/67. Heading B4C. A cartridge-actuated tool comprises a sleeve 86 slidably mounted in a housing 4 between a firing and neutral position and a fastener 140 and a cartridge mounted in a disposable tube adapted to be inserted into the sleeve and releasably secured therein. The sleeve 86 is provided with a breech plug 88 and is loaded by a spring 94 to the position shown wherein the end of a slot 106 in a splinter-shield assembly 98 abuts a spring-loaded plug 108. A firing pin assembly 22 is mounted in the rear end of the housing and is cocked and fired by a lever 64. The cartridge 132 is secured in the end of the tube 130 by a suitable synthetic plastics material and upon insertion of the fastener into the tube, the latter is closed by a cap 144 which may be colour-coded to indicate the power level of the cartridge. In operation, the firing pin is cocked as shown and a loaded fastener tube 130 inserted into the sleeve. The shield, together with the end cap 144, are pushed against a workpiece thereby causing the sleeve to be moved rearwardly so that the breech plug 88 is in the firing position. The lever is then operated causing the firing pin to fire the cartridge.

Abstract: 1,026,970. Making electrical connections. AMP Inc. Jan. 22, 1965 [Feb. 12, 1964], No. 2826/65. Heading B3A. In apparatus for effecting an electrical connection between a wire and a terminal post by means of a connector or clip 2, Fig. 15 (not shown), the leading clip is held between surfaces 114, 118 or stops 80, 82 respectively and as the halves of an operating handle are squeezed together a cam surface 106 on a lever 88 abuts a pin 108, thereby depressing the stop 80. A clip pusher 72 moves the strip of clips forwardly and after the pin 108 has moved past the cam surface 106 the spring 86 resets the stop 80 so that the following clip abuts the surface 114. Further pressure on the handle separates the leading clip from the strip, pushes it on to a mandrel portion 136 and the clip severs the insulation of the wire in the opening 124. When the clip overhangs the mandrel head 130 the tool is placed over a post 12 (Fig. 4, not shown) so that it abuts a surface 134 of the head 130. The tool is then pressed downwardly causing the clip pusher 72 to move forwardly relative to the mandrel, thereby forcing the clip along the post with the bared wire trapped therebetween.

Abstract: 485,781. Amusement apparatus. HANDS, F. C. Jan. 30, 1937, No. 2833. [Class 132 (i)] An amusement apparatus comprises a number of vehicles or trucks accommodating the feet of the passengers, who are carried in a substantially erect position by holding hand-gripping means located a suitable distance above said vehicles. The trucks 11 are drawn along an undulating track or platform 10 by means of links 17 connecting the trucks to vertical rods 16 which are propelled, preferably in a closed circuit, by any suitable means. An overhead revolving structure supported on a central driven shaft is described for carrying the rods 16. Passengers hold hand grips 19 rigid with the rods 16. Each truck lags behind its hand grip when ascending a slope and overtakes it in the descent, giving to the passengers a skidding sensation. The path of the trucks may also be sinuous in plan. In modifications, the trucks may be formed to represent skis and the feet of the passengers may be accommodated by individual trucks loosely linked together, and the connections between the trucks and the propelling means may have universal joints.
