Title: Seal for use in control system positioning devices
IPC: F16J15/32
Filed: 1971-12-29
Abstract: 1405410 Fluid-pressure servomotor systems HORNE ENG CO Ltd 29 Nov 1972 [29 Dec 1971] 60591/71 Heading G3P [Also in Division F2] An arrangement, e.g. for controlling the flow of high pressure steam into a heat exchanger chamber, comprises a thermostatic pilot valve 14 associated with a valve 1 including steam inlet and outlet bores 3, 4 and a closure disc 6. With the valve 14 open, steam flows through a bore 12 around a spindle 11 to a cylinder chamber 13a, further flowing through conduits 15, 16 to a chamber 13b, so that equalized pressures on a piston 9 allow the steam pressure to raise the disc 6 from its seat. When the temperature in the chamber has reached a predetermined value a thermostatic element 24 acts to close the valve 14, pressure escaping from the chamber 13b through a bleed orifice 28, so that the pressure in the chamber 13a closes the valve 1.

IPC: E05B3/06
Filed: 1968-12-20
Abstract: 1285448 Handle assemblies EATON YALE & TOWNE Inc 17 Oct 1969 [20 Dec 1968] 60796/68 Heading E2A  A spring loaded handle assembly comprises a handle 10 having an internal annular recess 11 surrounding a central spigot 12, the spigot having the hole 13 which receives a latch operating spindle 14 the. handle being rotatable with respect to a spring housing 16 mounted in the recess, a spring 18 within the spring housing, a mounting member 22 non- rotatably engaged with the spring housing, the mounting member being non-rotatably securable to a door, a part 27 disposed between the spring housing and said mounting member, the part being non-rotatably retained on the spigot of the handle against axial movement and restraining axial movement of the spring housing, said part having a projection 28 engaged with one end of the spring and forming a spring abutment, stop means 19 which limits relative rotatation between the part and the spring housing, and the handle carrying retaining means 32 which retain the spindle therein. In the construction shown the spring housing has three lobes 21 which are received in three spaced recesses in the mounting member 22 to prevent rotation between the housing and the mounting member. The part 27 in addition to the projection 28 which is engaged by one end of the spring has three ears 30, faces of which can be engaged by the stop means 19 which is in the form of a steel pin 19 carried by the spring housing; the part 27 is symmetrical about its centre line so that rotation of the handle in alternative directions is controlled by the engagement of the pin with alternative pairs of faces of the ears 30. The spring housing and the part 27 are retained on the spigot 12 against axial movement by spreading the end portion of the spigot outwardly to overlie the edges of the hole 29 in the part 27. The mounting member 22 shown has the same external diameter as the handle boss and it is held to the door by four screws 23, the correct position of the mounting member on the door being determined by first inserting the spindle 14 into the latch and then placing a piece (not shown) on the spindle, the piece having a square hole for engaging the spindle and a non-circular periphery which fits a non-circular hole 26 in the centre of the mounting member. When the mounting member has been secured to the door the piece is removed and the remainder of the assembly secured in place. In a modification a plate can be disposed between the mounting member 22 and the door the screws 23 passing through both the mounting member and the plate.

Core sampling apparatus for use for example on the sea floor comprises a frame, a core tube 3 extending through the frame, a vibrator to move the tube into the soil, and core tube hoisting means on the frame. The frame comprises hollow columns 8 and 9, and support arms 19 pivoted at 20 to the base of the frame and movable by hydraulic cylinders 21 between a retracted position with the arms parallel to the columns and the extended position illustrated. The tube 3 is connected to the tube 6 of the vibrator which is so mounted in a housing 7 that the housing does not vibrate. The housing 7 has guide rollers 18 engaging the columns, and is supported and moved vertically by chains 13 and 14 extending through the columns and driven by a hydraulic motor through sprockets at the bottom of the columns. The vibrator may comprise a pair of weights eccentrically mounted on rotating shafts. Alternatively (Figure 4 not shown) each weight may be replaced by a pair of spheres of different weights and mounted by arms at adjustable distances from the axis of a shaft. A suction pump (Figure 9 not shown) may be mounted inside the top of the core tube and may comprise a housing for a ball valve allowing air to pass upwardly from the tube and a piston mounted above the housing and connected thereto by a spring, and also allowing air only to pass upwardly. In a modification the core tube extends through the vibrator and is alternately gripped by means (Figures 5-8 not shown) on the vibrator and at the foot of the column so that the tube can be held while the vibrator moves relatively thereto to feed an additional length into the ground.

Patent GB-777526-A (GB)
Abstract: 777,526. Spinning frame driving means; control arrangements. BREMATEX. June 17, 1955 [July 1, 1954], No. 17613/55. Class 120 (2). A ring spinning frame having variable speed driving means and means for controlling the ring rail in such a manner that it reaches relatively to the spindles an end position at the end of winding up of yarn on the cops, is characterized in that it includes means arranged so that, when the ring rail reaches this end position, the speed at which the spinning frame is driven is automatically reduced from its normal running value to a given lower value suitable for the subsequent under-winding of the finished cops. In the arrangement shown the spinning frame is driven by an electric motor 1 the speed of which can be adjusted by displacement of the brushes thereof by the shaft 8. To slow down the speed of motor 1 from its normal running speed to a given lower speed suitable for the under-winding operation when the ring rail 5 reaches its uppermost position with respect to spindles 4 the control shaft 8 is connected to a spindle 10 by means of a chain 11. Spindle 10 is connected with a fixed pin 12 rigid with a plate 6 through a spiral spring 13 which tends to rotate the spindle 10 in the direction corresponding to a reduction of the speed of the motor down to a position determined by an abutment 14 corresponding to the lower speed required. A ratchet wheel 15 adapted to co-operate with a pawl 16 is fixed to the spindle 10, the pawl 16 being carried by lever 17 the other end of which carries a finger 18 located across the path of movement of an adjustable abutment 19 carried by the ring rail. The arrangement is such that when this abutment 19 contacts the finger 18 the pawl 16 is disengaged from the ratchet wheel 15 such that the latter is released and the spindle 10 is rotated by the spring 13 until stopped by abutment 14 the motor thus being caused to slow down to its lower speed. A hand wheel 9 is provided on spindle 10 for resetting purposes. A push button 20 which controls the starting of the motor 1 is arranged so as to be masked by hand wheel 9 such that it can only be operated when the wheel 9 is in a position corresponding to the lower speed of the motor.

Title: Simulator for Doppler VOR signals
IPC: G01S1/40
Filed: 1980-01-31
Abstract: A simulator for Doppler VOR signals includes sources for carrier frequency (1), 30 Hz reference frequency (2), variable phase 30 Hz frequency (3) and baseband frequency (4). Programmable read only memories (PROM's) (8a, 8b) control up/down counters (5a, 5b) to generate antenna phase jump functions which in turn drive sinusoid function generating PROM's (6a, 6b) the outputs of which modulate a proportion of the carrier frequency to generate simulated upper and lower sidebands. The sidebands are further modulated by outputs by PROM's (20a, 20b) which impose blending laws on the sidebands before the sidebands are combined (25) with the rest of the carrier and the 30 Hz reference signal. The variable phase 30 Hz signal controls a phase locked loop including counters (17a, 17b) from which stepping control signals are derived for the phase jump PROM's. <IMAGE>
