Abstract: 614,274. Guards for engine air intakes. ELLIOTT, A. G. July 9, 1946, No. 20524. [Class 4] A guard grid for the inlet of an engine air intake is curved or bent to project forwardly from a pair of opposite edges of the intake. Fig. 1 shows a circular grid 14 for the intake of a gas turbine 12 mounted in a nacelle 10, the grid being of approximately spherical crosssection. The grid is mounted on lugs 16 leaving an annular space 17 for the admission of air in the event of the grid being obstructed by an accumulation of ice or snow. Fig. 3 shows an elongated grid 22 mounted on the leading edge of a wing 20 and curved to conform thereto, gaps 24 being provided at the upper and lower edges. The grid may be insulated from the aircraft structure and electric current passed through it, to heat the incoming air or to melt accumulated ice or snow.

Title: Improvements in switching devices
IPC: H01H51/28
Filed: 1923-08-14
Abstract: 224,940. Western Electric Co., Ltd., (Western Electric Co., Inc.). Aug. 14, 1923. Contact-making relays.-A vibratory switch contained in a sealed receptacle and especially intended for a relay, comprises a pair of apertured members and peg-like members projecting into or through the apertures. The switch is carried by a vibratory element, such as a diaphragm or reed, which actuates the switch in response to interrupted vibrations in a first circuit whereby control of vibrations in a second circuit is effected. As shown in Figs. 1 and 2, a sealed receptacle 16 is mounted on a diaphragm 10 by means of a socket 13. Leading, in terminals 17 at the ends of the. receptacle are connected with metal discs 15 having central holes 25 with which engage pegs 14 at the ends of a loose contact member 18. When the diaghragm vibrates, the contact member 18 is agitated and the second circuit is broken. With the circuit arrangement shown in Fig. 1, when a switch 33 in the first circuit is closed, alternating current from a source 35 passes through the windings 8 and vibrates the diaphragm 10, the second' circuit, which contains a source B of direct current and a relay 34, being thereby broken. When the train of vibrations in the first circuit is inerrupted by an impulse sender 36, corresponding direct current impulses are produced in the second circuit. Instead of a direct current source B, an alternating current source may be used. The loose contact may take, various forms, for instance, it may be tapered so that the ends, being of different weights, vibrate out of phase, or it may comprise two balls or cups of different weights connected by a flexible rod. In a modification, Figs. 4 and 4a, the vibratory switch opens the, circuit when it is still and closes it when it is vibrating. The loose contact comprises two weights 40 joined by a rod 43 and having projecting pegs 3 resting on insulated material 31 at the bottom of borings in cup-shaped contact pieces 30. A very slight clearance is provided between the pins 3 and the upper wall of the cups, so that the circuit is closed when the loose contact is agitated. Two vibratory switches may be mounted on the same diaphragm or reed so that a single primary circuit controls two secondary .circuits. In the construction shown in Fig. 12, the vibratory switch 120 is carried bv a reed 117 at each side of which is an adjustable stop 125. A modification employing a reed is shown in Fig. 17. A source of alternating current 143 is normally connected to the conductors 138 of the, winding 114, or to separate windings. the frequency being such that the vibrating reed does not operate the switch 121. For the purpose of actuating the switch, a sender S and switch 135 are employed to superimpose current from a second source 136 of a different frequency.

Abstract: 672,729. Two-way transmission. DEHN, S. G. (Automatic Electric Laboratories, Inc.). Aug. 11, 1949, No. 20929/49. Class 40 (iv). In a two-way carrier current terminal equipment a balanced modulator and an amplifier effect the transference of signals both from a low-frequency line 1 to a high-frequency line 73 and vice versa. In the arrangement shown, the audio signal from line 1 is applied to the centre taps of the modulator transformers 33 and 35 via transformers 11 and 19 and a resistor 17 which is of such a value as to absorb approximately half the signal so that the arrangement comprises a differential transformer. The modulated output, after amplification, is passed via a directional filter 63 to the H.F. line and the carrier is suppressed by a tuned circuit 58, 60. H.F. signals are also applied to the modulator through the transformer 19 via a directional filter 65, but the L.F. output is in this case selected by a low-pass filter 79 and applied to line 1 at the points 81 and 83 of the hybrid.

Title: Improvements in or relating to machine feeding arrangements
Inventor: GRAY FRANK
IPC: B21D43/02
Filed: 1957-07-03
Abstract: 829,962. Metal sheet feeds. STANDARD TELEPHONES & CABLES Ltd. July 3, 1957, No. 20961/57. Class 83 (4). [Also in Group XXX] Apparatus supplies stock to the feed device of an automatic machinetool in response to actuation of a detector in the machine-tool when the piece of stock being worked is used up or reaches scrap length. The apparatus feeds pairs of strips from magazines to a press and removes the scrap lengths from the press. When the detectors, e.g. photo-electric devices, are operated to indicate that both strips have reached scrap length the apparatus shown in plan in Figs. 1, 2, 3 is set in motion to release a pneumatically-actuated clutch to stop the press. Grippers 11, Figs. 1, 7, 8, on a carriage consisting of interconnected frames 5, 6, are pneumatically actuated by cylinders 12 to grip the scrap lengths in the press. Should the grippers fail in this, switches 22 actuated by complete closure of the grippers, stop the apparatus. The lowest strips 1 in each of two magazines shown in Figs. 14, 15, which are sections on lines FF, GG, Fig. 2, are pushed transversely into slots 65, 73 of four frames spaced along the feed path and having supports such as 74, 68 for holding the strips. The pushing is effected by blades 13 pivotally connected at each end to pneumatically-actuated pistons in cylinders 14. Pneumatic clamps 15 secure the strips 1 in the slots 65, 73 while a doubleacting pneumatic motor 17 returns the carriage, and the forward ends of the clamped strips 1 pass between guides in the rear frame 5 of the carriage. The grippers 11 release the scrap portions which drop into a container and pneumatic clamps 21 on the frame 6 engage the edges of the strips 1. The clamps 15 release and the carriage is returned to its forward position whereupon clamps 21 are released and the rear ends of the partially advanced strips are again secured in the slots 65, 73 by the clamps 15. The carriage is again reciprocated with interacting operation of the clamps 15, 21 and the grippers 11 to complete the feeding of the strips 1 to the press. The clamps are released and the press restarted to work on the strips 1. The cycle of operations is effected pneumatically under the control of valves 90, Fig. 3, actuated electromagnetically in response to switches adapted to be closed by cams 98 on a shaft 95 rotated once for each cycle. The cams consist of sectors held between discs 119 on the shaft 95 and are adjustable to cater for any requirements.

The adapter may comprise an auxiliary conductive member 6 to extend the effective length of the first battery or an insulating member to increase the effective diameter of the first cell or both. In the embodiment of Fig. 1 a Ni-Cd cell 2 has its length effectively increased by conductive member 6 supported in a tubular insulating body 7 of the same diameter as cell 2. Sufficient space is provided for finger insertion between the tip of member 6 and the body 7.
