Title: Liquid metering apparatus
Inventor: CURTIS PETER EDWARD
IPC: G01F3/38
Filed: 1969-04-08
Abstract: 1,253,283. Dispensing measured quantities of liquids. ILFORD Ltd. 2 April, 1970 [8 April, 1969], No. 17827/69. Heading B8N. An apparatus for dispensing measured quantities of liquid comprises a vessel 1, liquid level sensors associated with the vessel, and an inlet including two branches, one permitting flow of liquid at one rate and the second permitting flow of liquid at a slower rate. As illustrated the sensors are electrical contact probes 3, 4, 5, and the second branch 12 of the inlet 13 includes a restriction 16. The probes through suitable control circuitry (not shown) control the inlet valves 14, 15 and an outlet valve 7. Initially the valves are closed. To dispense a measured quantity valve 14 is first opened and when the liquid contacts the probe 4 the valve 14 is closed and valve 15 is opened thus permitting flow of liquid into the vessel at a slower rate. When the probe 5 is contacted by the liquid the valve 15 is closed and after a preset time interval the outlet valve 7 is opened. Uncovering of probe 3 causes the valve 7 to close. The valve 7 upon closing may energize a relay which causes the inlet valve 14 to open if a number of volumes of liquid is required. A plurality of such apparatuses each having a vessel of different volume, e.g. 1 unit volume, 10 unit volumes and 100 unit volumes, may be included in a system for dispensing liquid quantities, the system including a control for effecting operation of each apparatus a required number of times in order to dispense a required quantity from the system. The apparatus may include an outlet having two branches for feeding liquid at one rate and at a slower rate, valves in the branches being controlled by the probe 3 and an additional probe (30) (Fig. 3, not shown) in a manner similar to that described above. Each sensor may comprise a light source and corresponding photo-cell placed outside the vessel which will then be transparent, or a geiger counter placed outside the vessel. In the latter case a radio-active source will be present on a float.

Filed: 1934-06-18
Abstract: 439,961. Preventing reverse movement. TALBOT, A. W., 1411, 4th Avenue, Seattle, Washington, U.S.A. June 18, 1934, No. 17975. [Class 103 (i)] A device for preventing reverse movement of a shaft, particularly for motor vehicles and which is rendered effective only in low-speed forward gear setting comprises a disc 33 secured to the drive shaft 19 and rollers 47 adapted to wedge in inclined recesses between the disc and a ring 41 supported on the disc by ball-bearings 45 at each side of the rollers. The ring is adapted to be locked by the engagement of external teeth 41<1> thereon with interior teeth 48<1> on an outer axially slidable ring 48 having splines 49 slidable in grooves in the casing 10. The splines are connected by a fork 51 to one of the gear shift rods 27 so that when the rod is moved by lever 32 to engage gear 23 with gear 52 for low-speed forward drive the rings 48, 41 are engaged and the device is effective while in neutral, reverse and other forward speed positions of the gear lever the rings are disengaged. The rings overlap in the disengaged position so that the lubricant in the annular, space between them acts as a drag on the ring 41 and facilitates meshing. The device is enclosed in a casing 10 bolted at 12 to the gear casing 9 and by removing cover 30, bolts 12 and 53, the casing 10 with the device and shaft 19 can be removed.

Title: Improvements in or relating to power transmission apparatus
IPC: F16H3/60
Filed: 1948-07-05
Abstract: 663,078. Controlling reversing gearing. MATHERS, J. H., (trading as MATHWAY MARINE). July 25, 1949 [July 5, 1948], No. 18066/48. Class 80 (ii) [Also in Group XXXIII] In a reversing gear for marine craft with a clutch 36, 47 for ahead drive and a brake 83 for astern drive as in Specification 690,378, and with a single central spindle 100, connected to the ship's telegraph, for both the gear and the engine throttle, alternative engagement of the clutch and brake is effected, via levers 85 and 119, by servomotor pistons 88 and 124 respectively, the supply of pressure oil from a chamber 109 fed by a pump 104 being controlled by a rotary valve 99 on the spindle 100, while the linkage between the spindle 100 and the throttle includes a lever 149 which is normally without a fulcrum so that the linkage is ineffective to actuate the throttle until one or other of the pistons 88, 124 has moved outwards to engage the clutch or brake and uncover a port 135 whereby pressure oil passes to a third servomotor to move its spring-loaded piston 137 outwards to engage a projection 152 on the lever 149 and thus constitute a fulcrum for the lever and render the linkage effective for opening the throttle on further rotation of the spindle 100. The three servomotor cylinders 89, 115 and 136 are formed in a single block 90, Figs. 7 and 9, carried by a casting 96 secured to the top of the gear casing 91, Fig. 1. The pump is driven by a shaft 105 within the output shaft 53 and driven from the input member 20. At the end of its outward movement, the piston 157 uncovers a port 140 whereby oil escapes into a tube 141 and thence through a pipe 142 into the ported hollow shaft 53 for lubricating the gearing. The port 140 also leads to the cylinder 89 so that, during ahead drive, oil passes also through ducts 94, 95 in the piston 88 and drains on to the reduction gearing 181, 182. The tube 141 contains a spring-loaded valve 161 for relieving excess pressure in the chamber 109. The valve 99 has ahead, neutral and astern positions, and the ports are such that when either of the servomotors 89, 115 is energised the other is exhausted. The cylinders 136 exhausts via port 135 and ducts 94, 95 or 125, 126 in piston 88 or 124 when the latter moves inwards on deenergisation. The throttle linkage comprises a spindle 147 connected to the throttle and having an arm 148 with a pin-and-slot connection 155 with one end of lever 149, the other end of which is pivoted on a block 151 slidable on the tube 141 and connected by rod 153 and arm 154 to the spindle 100. The clutch and brake may be engaged, independently of the spindle 100, by means of an external hand lever. In a modification, two servomotors 136 are provided, one associated with each of the servomotors 89, 115, the two pistons acting alternatively to form a fulcrum for a pair of spaced connected levers 149.

Abstract: 1390635 Aerials LIGNES TELEGRAPHIQUES ET TELEPHONIQUES 19 April 1972 [22 April 1971] 18102/72 Addition to 1352406 Heading H4A An aerial array comprises a plurality of ementary aerials of the kind claimed in Specification 1,352,406, each being fed through a variable phase shifter from a common source. Scanning is obtained by adjustment of said phase shifters, and the angular width of the beam from the array is controlled by adjustment of the currents in the magnetizing coils of the elementary aerials. As described, an array comprises a front current of twelve aerial elements 21 to 32, arranged in three rows and four columns. A similar rear curtain is spaced a quarter-wavelength behind the front curtain, and is fed 90 degrees out of phase therewith. Each aerial element comprises a ferri-magnetic spherical core with an associated magnetizing control winding, and an outer spherical shell of dielectric material. Radio frequency power is fed to a wave source at a point on the surface of said shell. The elements 21, 22, 25, 26, 29, 30 on the left-hand side of the array are fed co-phasally, and the elements 23, 24, 27, 28, 31, 32 on the right-hand side of the array are also fed co-phasally. Scanning may be effected by providing a phase difference between the two halves of the array. This is obtained by means of variable phase shifters 15, 16, 33, 34, 35, 36 which are interposed between a common source 19 and the various elements, and which are controlled by a circuit 37. Said control circuit also adjusts the currents to the magnetizing windings of the aerial elements to maintain, for example, a constant beam width for all scanning angles. As shown, the aerial elements are fed through waveguides, but coaxial or micro-strip lines may be used. In another embodiment, only two spherical aerial elements are used (Fig. 4, not shown). The arrays may comprise rod-type aerial elements, as described in the parent Specification, in place of spherical elements.
