Title: Improvements in or relating to high tension gas blast switches
Inventor: BIELIG HORST
IPC: H01H33/82
Filed: 1963-08-14
Abstract: 1,056,424. Gas blast switches. TRANSFORMATORENWERK KARL LIEBKNECHT VEB. Aug. 14, 1963, No. 32179/63. Heading H2B. A gas blast switch has main contacts 1, 2 arranged on a common axis with isolating contacts 3, 4, the circuit being initially broken by separation of main contacts 1, 2 and the isolating gap being established by the main contacts reclosing, a spring 11 being compressed by the opening movement of the main contacts and expanding to separate the isolating contacts. The switch housing 10 is filled with compressed gas; to open the contaets, spaces 6, 7 are vented through contact 4. Being nearest, space 6 is vented first so that piston 5 first moves downwards compressing spring 11; contact 2 follows to open the main contacts, a blast of gas proceeding through nozzle contact 1. Movement of piston 5 and thus contact 3 drives contact 4 downwards. Venting is then stopped and pressure reestablished in spaces 6, 7. Contact 3 first moves rapidly upwards under spring 11 to open the isolating contacts, followed more slowly by contact 2 returning to its closed position. In a second embodiment (Fig. 2, not shown) contact 2 is linked with piston 5 by a lost motion coupling comprising a piston 12; only space 6 is vented to open the contacts. Contact 3 initially moves down until the lost motion is taken up and then it draws contact 2 downwards. When pressure is returned to space 6 contact 3 moves upwards under spring 11 until piston 5 engages contact 2 and recloses it. In a third embodiment (Fig. 3, not shown) a strong spring is arranged between the small piston 12 and contact 3 the contacts being opened by drawing contact 3 downwards by means of a gripping contact 4 and then releasing it.

Abstract: 625,848. Sextants. CATRAVAS, S. J. Oct. 30, 1946, No. 32283. [Class 97 (ii)] In a sextant wherein the altitude of an object is read off on the image of a scale adapted to be moved automatically within the field of view of a viewing telescope, the scale is mounted upon a gravity-controlled pendulum member. The object n whose altitude is to be determined is viewed in a telescope a mounted in a casing b together with the image of a scale e mounted on a pendulum c pivoted on anti-friction pivots d secured to the casing. The scale may be translucent, and the portion viewed in the telescope a by the mirrors i, k, m may be illuminated by a lamp f. A further mirror j may be mounted in the optical system and carried on a small pendulum swinging on pivots o so that any displacement of the sextant from a vertical plane containing the viewing axis may be indicated to the observer. An embodiment is described in which the pendulum is mounted to pivot on knife edge bearings during an observation, but is provided with means to lift the knife edge from its pivot surface when not in use and to transfer the weight of the pendulum through two pairs of conical rollers to a pair of guide rails mounted in the casing, the control knob for this means also serving to control the current to the scale-illuminating lamp and to start or stop a clockwork mechanism which imparts vibratory movement to two rods designed to impact periodically the sides of the pendulum and thus dampen its vibration and also locking means are provided to cage the pendulum and to lock the control mechanism above referred to. Specification 588,290 is referred to.

Title: Improvements in iris diaphragms

Abstract: 912,017. Iris diaphragms. WRAY (OPTICAL WORKS) Ltd. June 24, 1960 [Sept. 25, 1959], No. 32736/59. Class 97 (1). An iris diaphragm in which the two plates on which are mounted the leaves forms the adjustable substantially circular aperture of the diaphragm are moved relatively to one another, to adjust the aperture, by means of an operating member, the rotation of which to enlarge the aperture causes movement first in one direction and then in the opposite direction of a gear member which is coupled to one of the plates and so first decreases and then increases the rate at which the aperture opens. Preferably, the angular movements of the operating member between all consecutive standard apertures are substantially equal. As shown in Fig. 1, the diaphragm leaves 5 are each pivoted to a plate 2 and a plate 7. The plate 2 is rotated by a sleeve 1 which surrounds the lens mount 4 and is connected to the plate 2 by a pin 3 extending through a circumferential slot in the lens mount 4. The plate 7 is also rotated relative to the lens mount 4, this plate having rigidly mounted thereon a hollow cylinder 12 with teeth 14 which mesh with a gear 16 on a shaft 17 terminating in a pinion 18 that engages with a rack 19 carrying a pin 20 which extends through a slot 21 in the sleeve 1. This slot 21 is such that as sleeve 1 is rotated to adjust the diaphragm aperture, the rack 19 will be moved axially first in one direction and then the other so as to produce a corresponding movement in plate 7. In a second form, one of the plates is fixed and the other plate is rotated by a gear segment which is pivoted to the rotatable sleeve 1 and carries a pin engaging a fixed cam on the lens mount 4, this cam being designed to alter the rate of movement of the movable plate with respect to the sleeve 1.

Title: Improvements in or relating to distant control mechanism
IPC: F03B15/00
Filed: 1919-12-31
Abstract: 137,321. Englesson, J. E. Dec. 31, 1918, [Convention date]. Transmitting-mechanism; fluid relays.-A device for operating the starting and stopping gear of a water or other turbine is controlled automatically by clockwork or electrically from a distant point, and may be connected with a centrifugal governor acting through a fluid relay. It is actuated, in the movement which stops the turbine, by oil under pressure from a turbine-driven pump, and in that movement raises a weight, compresses a spring; or otherwise stores up energy for its own actuation in the movement which restarts the turbine. A valve 6 can be turned through an angle by means of electro-magnets 17, 18, which are energized in turn. When one is energized, the valve is turned to connect the pressure oil pipe 8 with a cylinder 1 and a piston 2 is lifted and. the spring 4 compressed. In the movement the piston-rod 19 engages a weight 14 by means of the parts 39, 40 and raises it and a latch 25 snaps over the top of a sleeve 28 on the turbine starting lever. When the second electro-magnet is actuated, the valve rod 7 is turned in the opposite direction and the cylinder 1 is connected to the outlet 10. The weight also is turned with the valve rod, is released from the part 40 and, in falling upon a latch 37, removes it and permits the spring 4 to drive the piston 2 downwards. The piston-rod is at first coupled to the sleeve 28 by the latch 25, and the sleeve is therefore moved downwards and the turbine started. Later, the plate 27 engages the end 26 of the latch and it is withdrawn. As shown in Fig. 3, a centrifugal governor controls a valve 41 in a piston 33 subject to fluid pressure. The piston is connected, as shown, to a spindle 31, controlling the throttle valve. When the speed rises above the normal, the valve 41 is opened and pressure fluid passes to the upper side of the piston 33 and depresses it to close the throttle valve. The lever 42 is pivoted to the rod of a piston which is pressed upwards by a piston in a cylinder, the upper end of which is connected by a pipe 49 to the lower end of the cylinder 1.
