Title: Improvements in lifeguards and obstruction removers for road and other vehicles
IPC: B60R21/34
Filed: 1934-05-11
Abstract: 438,055. Vehicle lifeguards. SAFETY BUMPERS, Ltd., CLIFFORD, V. J., and GEORGE, S. V., 15, Princes Row, Westminster. May 11, 1934, No. 14326. [Class 103 (ii)] In a roller lifeguard for a vehicle an end portion oi the roller is resiliently connected to the main portion so that it may flex in any direction away from its normal position, in alignment with the main portion, on encountering a kerb or like obstacle, and return automatically to its normal position on leaving the obstacle. As shown a tubular driving-shaft 10 forming part of the main portion of the roller, projects beyond a bearing housing 11 and supports externally a bush 12 and internally a tube 14 which are secured together by screws 13. A mass 16 of sponge rubber keyed to the bush 12 and enclosed by a tough rubber or other sheath 17 extending over the bush, is reinforced by a spring 15 wound on the tube 14 in such a manner that rotation of the shaft 10 tends to tighten the spring. In a modification the spring is tapered towards its free end and is held against the tube 14 by undercutting the bush 12. In further constructions (not shown), the end portion of the roller is formed (a) entirely by a closely-wound helical spring and (b) of rubber &c. reinforced by flat metal springs or resilient rods. The roller may be resilient throughout the major portion of its length. The invention may be applied to the lower roller of the double roller arrangement described in Specification 427,127. Specification 5585/01, [Class 103], also is referred to.

Patent GB-625407-A (GB)
Title: Improvements in or relating to radio transmitters
IPC: H04L27/04
Filed: 1938-05-13
Abstract: 625,407. Pulsing carrier frequencies. DODDS, J. M., LUDLOW, J. H., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. May 13, 1938, No. 14374. [Class 40 (v)] In a radio transmitter arranged to transmit rapid changes in carrier level, e.g. for " marks " and " spaces," signal distortion due to exponential growth 2, Fig. 2, and/or decay 3 of the transmitted pulse is reduced by applying additional pulses 4, 5 to increase the rate of growth 8 and/or decay 10 of the signal waveform. This is accomplished as shown in Fig. 3, by two amplifiers 5, 6 connected in anti-phase with the carrier source 1 and grid-controlled by a signal controlling device 9 which receives the original signals on terminals 13. The arrangement is such that on the arrival of the signal front, the impulse 4 is generated in the device 9 by a condenser-resistance switching device, Fig. 4 (not shown), which at the termination of the signal pulse also produces the anti-phase pulse 5. The parallel output connection of the amplifiers 5, 6 ensures that no energy of carrier frequency reaches the final amplifier 12 of the transmitter during " space " periods.

Title: Improvements in stopping and starting arrangements for weaving looms
IPC: D03D51/00
Filed: 1932-05-23
Abstract: 392,740. Loom stopping and starting mechanism. CAMPS, J. P., 80, Colomer Street, Sabadell, Spain. May 23, 1932, No. 14555. [Class 142 (i).] A cone clutch on the driving-shaft and an internal expanding brake in a brake drum are normally under control of the usual stop-rod dagger and frog or stop, so that when a shutter is not properly boxed, the clutch is disconnected and the brake is applied simultaneously when the lay beats up. A hand-wheel is provided for disconnecting the clutch and, at the same time releasing a normally-idle dagger loose on the stop-rod into the path of the frog, so that, at the beat-up, the brake is then applied. To re-start the loom, the hand-wheel is turned to raise the idle dagger and put the clutch in. When the shuttle is not properly boxed, the usual dagger Q engages the frog T and moves it against the action of a spring X to turn a lever Z to apply a brake E by the mechanism shown while, at the same time, a cam surface T<1> on the frog T engages and depresses a stop S on an arm b pivoted to the loom frame and engaging a vertically-movable rod U controlling the clutch mechanism and adapted to be operated independently by the hand-wheel V. When the hand-wheel is turned to stop the loom, a guide surface R carried by the rod U is lowered and a dagger P (shown in dotted lines) loose on the stop-rod is allowed to fall into position to engage the frog T and to apply the brake at the beat-up. On turning the wheel V to re-start the loom, the surface R again raises the dagger P out of the path of the frog, and the spring X turns the lever Z to remove the brake from the brake drum. To lessen the shock on stopping the loom, the frog T is connected by a spring X<1> with a sliding part Y connected to the lever Z.

Abstract: 489,091. Knitting machines. DEHN, F. B. (Textile Machine Works) Oct. 14, 1936, No. 14855 /38. Divided out of 487,148. [Class 74 (ii)] In a straight-bar machine, yarn carriers are selectively engaged by means carried by the friction-box, and actuated by cams on the friction box always in engagement with driving means not movable longitudinally of the machine. A friction-box 173, Fig. 5, on friction rod 172, carries a bracket with shaft 178 on which is mounted a rocking member 166, in which slides a rod 183 on which is mounted a member 182 with tongues 185, 186, for engaging dogs 187, 188, 189, on yarn carrier rods 102, 103, 105. The rod 183 is manipulated by a handle 184 and held in or out of operative position by a spring detent 190. The member 166 has rollers 179, 180 bearing on cams 164, 165 splined to a shaft 163, and moving with the friction-box. Rotation of the cams 164, 165 to rock the member 166, and move one of the tongues 185, 186 from one carrier-rod dog to another, is effected by a ratchet 235, Fig. 9, fast on the shaft 163, and stepped round by a pawl 233 on an arm 230 reciprocated by a cam on the main cam-shaft. On a transverse shift of the main cam-shaft for narrowing, the cam actuating the arm 230 is moved out of the path of its follower, which now rides on a roller, and the selective operation is suspended. The cams shown in Fig. 5, ensure positive operation in both directions, and traverse three carriers in sequence, transferring at the end' of each course. Other forms of cam are described. To enable the transfer to be made at every second course, a second ratchet 270, Fig. 17, is freely mounted on the shaft 163, alongside the ratchet 235, and held by a pawl 271. Ratchet 270 has alternate deep and shallow teeth, so that the pawl 233 can only enter the teeth of the ratchet 235 at every second reciprocation of the arm 230. Details include a friction disc on the end of the shaft 163 to prevent overrunning, spring detents to prevent rebound of the yarn-carrier rods, a screw abutment for adjusting the end position of the friction-box, and a latch for holding the friction-box out of action.

May 24, 1933, No. 15024. [Class 8 (i)] Air compressors with two or more cylinders interconnected by a valve-controlled passage for unloading when a predetermined pressure is attained, are provided with a valve the movable element of which forms parts of the connecting passage. An oscillatory Corlisstype valve or a rotary or axially movable valve may be employed and alternatively a solid valve with passages thereon may be used. The valve axis may be parallel with the axis of the crankshaft and the valve may be disposed substantially tangentially to the cylinder bores. Cylinders 1, 2 have ports 3, 4 adapted to be connected to a transfer passage 5 by a valve 7. The valve carries an arm 8 which engages a control valve 9 movable in the cylinder 10 under the action of pressure in pipes 13, 14 connected to a control casing 11. When a definite pressure is reached the pilot valve 12 is lifted, the member 9 is moved and the valve 7 turned to the unloading position. Simultaneously pressure air flows through the port 18 and acts upon the control of the prime mover. An adjustable needle valve 19 is provided for varying the rate of flow from the pipe 13. In addition the inlet air suction port can be closed simultaneously with the opening of the unloading valve. Instead of unloading all the cylinders simultaneously, they may be unloaded in stages by providing additional pilot valves to operate at pressures other than the normal unloading pressure.

Abstract: 594,531. Aerials. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 8, 1944, No. 15096. Convention date, June 3, 1942. [Class 40 (v)] Relates to '' end-fire " arrays comprising three dipoles 11, 12 and 13 with a spacing of #/4 energized from a centre-fed transmission line 15 with a transposition 9 so that the end dipoles are energized in anti-phase and the centre dipole is energized in phase quadrature with respect to the end dipoles. According to the invention, such an array is arranged with its plane normal or parallel to a conductive sheet, e.g. the fuselage or wing of an aircraft, with the longitudinal axis of the array parallel, to the sheet, the spacing of the array from the sheet and its distance from the edge of the sheet in the direction of the longitudinal axis being such that the line of maximum directivity forms an angle of the order of 20 degrees with the longitudinal axis. The characteristic impedance of the transmission line 15 is made twice the impedance of the centre dipole so that the current in the centre dipole is twice the current in the end dipoles and this reduces the formation of secondary lobes ; since the end dipoles are spaced #/4 from the feed point, the current in these dipoles is substantially independent of their impedance and the directivity of the array is therefore unaffected by variations of this impedance caused by weather. When mounted normal to the conductive sheet, two arrays 10 and 10<1> may be arranged in parallel planes and energized in phase from the transmission line TL, the variation of the gain with the spacing S being given in Fig. 4 (not shown).
