Title: Improvements relating to flashing apparatus for navigational and other lights
IPC: G08B5/40
Filed: 1933-03-27
Abstract: 417,261. Fluid - actuated valves. CHANCE BROS. & CO., Ltd., and SLIM, T. H., Glass Works, Smethwick, Birmingham. March 27, 1933, No. 9123. [Class 135.] In flashing-apparatus for navigational and other lights, the flashing mechanism is arranged in two chambers i, j closed respectively by diaphragms f, g, operatively connected to the mechanism, the chambers being superposed one over the other and over a third chamber h closed by a diaphragm e operatively connected to a pressure regulator for incoming gas. An open chamber k between the chambers i, j contains springs 2, 9 controlling the diaphragms f, g respectively. A spring o in the chamber o<1> controls the diaphragm e. The pressure regulator comprises a valve l loaded by a spring m and linked by a lever n and link p to the diaphragm e. The diaphragm f carries a tappet u, the upper or lower shoulder of which, when the pressure in the chamber 2 rises or falls sufficiently, engages a projection t on a member 24, which is pivoted at 25 and is engaged at opposite ends by pointed pressure pieces 26 acted on by springs 27. The lower shoulder acts through a slidable wedge v, adjusted by a screw w. When the projection t is engaged and the member 24 has been moved past the equilibrium position shown in the figures, the springs 27 cause it to snap over. During this movement, a screw 29 on one of a pair of arms 28 on the part 24 will strike a peg 30, and so will cause a member 20 (not shown), mounted similarly to the member 24 under the action of springs, to rock about its pivot 21. Hence one of the inlet and outlet valves r, s carried by the member 20 will be moved onto its seating r<1> or s<1>, and the other moved off its seating. The seatings r<1>, s<1> are at the open ends of passages leading into and out of the chamber i. Gas passes from the chamber h, through a passage and a choke in an enlargement in the casing b, into the chamber i, under the control of the valve r. Gas passes out of the chamber i, under control of the valve s, through a choke into the chamber j. The passage of gas from this chamber to the burners 5 is controlled by the diaphragm g, which is connected by a tappet 7 with a magnetized and pivoted bar 6, normally held close to its seating by magnetic attraction. The tappet 7 passes through a hollow part 11, and is adjustable by a lever 13 acting on a screw device 12. Long dark periods between flashes, and the total amount of gas for the flashing period, are controlled by the apparatus associated with the chamber i, and the frequency and duration of the short flashes are determined by the apparatus associated with the chamber j.

Title: Improvements in and relating to Projectile Fuzes.
IPC: F42C15/26
Filed: 1916-06-29
Abstract: 125,400. Rudge - Whitworth, Ltd., Pugh, J. V., and Pountney, F. June 29, 1916 Projectile fuses.-Relates to percussion fuses of the type comprising centrifugal safety means normally retained by a weighted tape which is held in place before the projectile is discharged, by a removable cover, and also comprising a firing- needle which on impact is forced to shear a retaining-pin. According to the invention, fusemechanism of the type set forth is combined with an adapter b which screws into the fuse-body and which consists of a one-piece cylindrical member having an external flange d, between which and the head i of the firing-needle f the centrifugal safety-device (consisting, in the constructions shown, of a split collar o) is retained by a tape p, the flange d supporting the shear-pin k and also making a damp-tight joint with the screwed cover r. The detonating-cap e may be mounted in a part separately screwed into the fuse-body. In the modification shown in Fig. 4, the cap e is carried by an inertia pellet t, which has a tubular extension t<1> slidable in the adapter. The pellet is normally locked by a centrifugal 'bolt u, which may be of the form described in Specification 125,401, co-operating with an inertia detent u' of known construction. In a further modification, a spring-pressed inertia pellet carrying a detonating- cap is slidably connected with the adapter by guide-rods. The ends of the rods pass through the adapter and abut against the centrifugal split collar, which thus controls both the direct-action striker and the inertia pellet.

Inventor: FORBES IAN STUART
IPC: G05B11/01
Filed: 1951-04-19
Abstract: 706,499. Automatic control systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 16, 1952 [April 19, 1951], No. 9211/51. Class 38 (4) As shown, in a closed sequence automatic control system, e.g. for maintaining the radio receiving aerial of a navigational aid continuously trained on a transmitter, a D.C. voltage, corresponding in polarity and magnitude to the sense and magnitude of error, is applied to terminals IN and controls, through thermionic amplifier valves 5, 7 and 8, the energization of a field winding 9 of a velodyne-type D.C. servomotor (not shown), the armature of which is constantly excited and runs in the appropriate direction to correct error. The output of valve 5 is also applied to the control grid of a valve 13 forming with a valve 14 a multivibrator circuit which takes up one or other of its stable states according to the polarity of the error voltage. Valves 13, 14 control the conductivity of gas-filled valves 18, 19 respectively so that a second field winding 10 of the servomotor is energized in a sense corresponding to the sense of error but to an extent which is independent of the magnitude of error. This second field winding is arranged to overcome servomotor stiction. A potentiometer 16 in the multivibrator circuit may be set to give unequal or unequal energizations of field winding 10 for' the two directions of rotation of the servomotor. The following modifications are referred to : (a) An additional armature input instead of or in addition to the additional field input. (b) Temporary increase of the additional servomotor input in accordance with armature current or speed. (c) Automatic elimination of the additional servomotor input when the servomotor reaches a predetermined speed or the error signal reaches a predetermined value.

As shown, applied to a variable speed gear, a pair of such sheaves are connected by a belt 26. Each disc 28 is mounted on a normally stationary shaft 29 which is threaded in a pair of spaced sleeves 40, 41. The two shafts 29 are interconnected by belts 49 and counter shaft 51 and one of the shafts 29 has an adjusting wheel 55. By means of the latter one pair of discs 27, 28, can be separated and the other pair can be moved towards one another whereby the speed ratio is varied. The counter shaft 51 is screwed at 57 to its support so that it moves axially with the shafts 29. Slackness occurring at the sleeves 40, 41, may be taken up by turning one of the sleeves relatively to the other. Removal of the driving belt may be accomplished by separating both sets of sheaves 27, 28, sufficiently to enable the belt to pass therebetween. Removable means, such as a rod 63, may engage the discs 27, 28, to prevent mutual relative rotation. The frame of the gear may comprise two identical members 8, 9, channel-shaped in cross-section and secured together by screws 11. The frame is mounted on posts 7 on a base A by bolts 10; rubber washers 12, 13, and a spacing sleeve 13a being used to keep the bolts from metallic contact with the frame.

Title: Treatment of porous bodies
Inventor: CHAMBERS HUBERT HAROLD
IPC: C23C16/04
Filed: 1959-03-20
Abstract: A porous sintered body is coated with a layer of reduced permeability by a vapour diffusion process in which the heated body is treated with the vapour of a volatile compound of the element to be deposited and the process is so controlled to give a point-to-point variation in the permeability of the outer layer. The material to be coated may be Ni, Co, Fe, Cr and their alloys, Mo and ceramics and the coating materials may be Si, B, Cr, Al or Zr in the form of halides or carbonyls.  The variation in the permeability of the outer layer is effected by screening part of the body to be coated by either packing part of the body in alumina or painting a part of the body with a slurry of alumina. The process is carried out in a non-oxidizing atmosphere such as hydrogen, argon or nitrogen.  In an example, a 80/20 Ni/Cr alloy is siliconized by heating to 1050 DEG C. in a vapour consisting of 2 parts volume SiCl4 and 98 parts volume hydrogen.  The process may be repeated so that two layers are deposited. Specification 783,710 is referred to.

Abstract: 195,527. Armstrong & Co., Ltd., J., and Lane, R. F. April 7, 1922. Ironing-machines with relatively-sliding flat surfaces.-In garment presses of the kind em. ploying a work-support 12 and a head 13 mounted on a lever 14, the head slides upon the work, after it has been brought into contact, owing to lost motion and other connections between the head and its supporting lever. In the form shown in Fig. 1, the head is attached to the lever by bolts 17 passing through slots 18. After the head has descended upon the work the lever can continue its downward movement and in so doing it slides the head toward the front of the machine by means of a pair of radius rods 20 pivoted to the head and lever. The final pressure takes place through the coacting surfaces 22, 23. In a similar arrangement the head is slid sideways instead of forwardly and rearwardly. In a further modification, Fig. 3, the head is mounted on its lever by slotted links 30 and the sliding motion is produced by the action of the wedge-shaped pressure surfaces 31, 32.
