Title: Yacht steering systems
IPC: B63H25/04
Filed: 1974-12-06
Abstract: 1485380 Reciprocating pumps: Hydraulic accumulators INDUSTRY SECRETARY OF STATE FOR 6 Dec 1974 [20 Dec 1973] 59252/73 Headings F1A and F1D [Also in Divisions B7 and G3]  A self-steering arrangement for a yacht comprises a hydraulic system to operate the helm in response to error signals, and the power for the system is derived from force variations that occur in a rope attached to the sail of the yacht. A pump 1 is pivotally connected to the yacht at 82, and has a piston 9 with a hollow connecting rod 4 connected to the rope at 5. The pump includes a reservoir 6, and a non-return valve 18. Outward reciprocation of the rod 4 and piston 9 due to tension in the rope cause fluid to be pumped from the cylinder 12 via a conduit 3 and non-return valve 18, to accumulator 21. The pressure fluid is augmented by flow from the cylinder space 11 via port 20, hollow stem 13 and non-return valve 15. When the rope slackens, pressure from the accumulator forces piston 9 backwards, and closes valve 18. The pressure drop in the space 11 causes fluid to flow from the reservoir 6 to the space 11  via non-return valve 15 and hollow stem 13. The sensing device comprises a wind vane 23, which is rotatable about a shaft 26 to actuate poppet valves 45, 46 and (47), (48), Fig. 4 (not shown) and control flow from an inlet 37, connected with the accumulator 21 to outlets (39), Fig. 4, and 40 connected with a double-acting ram on the yacht tiller. When a course correction has been made, the vane 23 is returned to its mid-position, and the poppet valves are allowed to close. Two pumps can be used.

Patent GB-681822-A (GB)
Abstract: 681,822. Hydraulic machines. ADROLIC ENGINEERING CO., Ltd., and McGADY, P. Jan. 1, 1951 [Jan. 5, 1950], No. 321/50. Class 69 (ii). In an hydraulically-operated power lift for tractorhauled agricultural implements comprising a piston 3, Fig. 2, and cylinder 1 a manually-operated main control valve 17, a pump driven by the tractor mover delivering oil under pressure to the control valve, and means 4, 5, 6 operated by the piston 3 by which an implement connected thereto can be raised, an auxiliary valve 31, Fig. 5, is manually operable so that the oil supplied thereto can be directed to operate another hydraulic appliance. The cylinder 1 is screwed into a block 2 having an inlet 9, a spring- loaded relief valve 11, passages 10, 12 and 13, bores 8 and 8a housing the main and auxiliary valves 17 and 31 respectively, and a chamber 14 housing a spring-loaded valve 14a and having connections 15 and 16 to the bore 8 and cylinder 1 respectively. The main valve 17, normally held in its neutral position by a spring 14b, has passages 18 and 19, and is secured to a stirrup 26 having rods 25 guided by a bracket 24 and carrying discs 23 overhanging the open end of the cylinder 1. The auxiliary valve 31 has passages 33, 34, 35, 36, and 37, and reduced portions 38, 39 forming egress passages for oil. On opposite sides of the valve are chambers 40 and 41 having non-return valves 40a and 41a and provided with passages 42 and 43 communicating with the bore 8a and ports 44 and 45 for connection to the two sides of a double-acting hydraulic appliance. When both valves 17 and 31 are in the neutral position (Fig. 5) oil flows from the inlet 9 through to passage 13 and out into the sump. When the main valve 17 is manually moved to the left, oil will flow from inlet 9 to passages 10, 18, 15, and past the valve 14a to connection 16 and into the cylinder 1 to move the piston 3 to the right until it contacts the discs 23 to move the valve 17 back to neutral. To retract the piston a spindle 28 is depressed to hold the valve 14a off its seat so that oil in the cylinder flows from connection 16 to passage 15 and through a slot 51 to a passage leading back to the sump. When it is desired to operate the appliance connected to the ports 44 and 45 the valve 31 is moved manually so that the passage 34 thereof is brought into register with the passage 42 or 43. For example, if the passage 34 is brought into register with the passage 43 oil will flow from passages 33, 34, 43, past valve 41a into port 45, and since a spindle 46 is depressed by a lug 48 to hold the valve 40a open, oil from the port 44 will flow past the valve 40a into passage 42 and through the egress 38 to the sump. In a modification the valve chamber 40 is connected to an additional non- return valve so that two non-return valves can be simultaneously held open to allow the ram or piston of the double-acting hydraulic appliance to float in its cylinder.

Abstract: 720,995. Electrolytic condensers. WESTERN ELECTRIC CO., Inc. June 16, 1953 [June 20 1952], No. 16553/53. Class 37. A condenser employs an electrolyte which contains from 2- 10 per cent of a stable nitrosoorganic compound to reduce deterioration of electrical properties with use. One embodiment of the invention is a rolled-foil type condenser, the foils of tantalum, aluminium, magnesium or beryllium, with terminals of the same material protruding from the ends of the roll have anodically formed oxide films on their surfaces and are spaced by a double layer of low density paper. The unit after impregnation with electrolyte containing nitroso-organic compounds is housed in a silver or silver-plated copper cylinder, the ends of which are closed by insulating spacers and cylindrical rubbery plugs held in place by crimping the ends of the cylinder, any free space in the housing being filled with electrolyte. In the other embodiment (Fig. 3) the cathode consists of a silver can 17, which is closed by a base-plate 16 and insulating washer 20, the joint being sealed by a gasket 19 of rubbery insulating material. The anode is a porous body 14 of tantalum powder sintered around a central pin 15, welded to the base-plate, and the whole container is filled with a fluid electrolyte such as an aqueous solution of lithium chloride, while a viscous type such as aqueous or non-aqueous glycol borate is preferred in the former embodiment. The nitroso-organic compound which must be stable against reaction with the electrolyte and decomposition by heat, is preferably a nitroso-aromatic compound. A list of suitable substances is given in the Specification.

Title: Jam-proof actuator structure
IPC: F16J10/02
Filed: 1978-07-12
Abstract: An actuator, and a system employing the same, which will continue to operate after deformation of a portion thereof, which deformation would normally restrict movement between the piston and cylinder of the actuator. The piston (50,52) or gland of the actuator is constructed so as to include segmented flanges (56,58) which will fracture responsive to forces applied to them upon engagement of the deformation. Slots (60) defining the segments are filled with a rubber-like material which is bonded to the piston or gland thus providing a solid structure to enable appropriate sealing while not interfering with the fracturability of the segments. <IMAGE>

Title: Monitoring movement and direction of movement of a member
IPC: G01D5/14
Filed: 1978-10-06
Abstract: Sensors (11, 12) which are flux gate magnetometers (Fig. 9, not shown) detect alternating magnetic poles on a rope (7) arranged in a mine shaft and derive electrical signal indicative of the passage of the poles and thus the speed of a mine cage associated with the rope. The signals are protected from common channel interference by circuitry (15, 16) and the speed and direction of the cage are determined by a logic unit (20). Error detection means (17, 18, 19) detect circuit faults which could give rise to misleading positional data. If the sensed speed is too high an alarm is given. The rope may support the mine cage or from a guide rope therefor (Fig. 7, not shown). Should either of the sensor circuits fail an alarm is triggered. <IMAGE>
