Patent GB-1414099-A (GB)
Title: Power transmission having a multiple plate friction clutch
IPC: F16D48/02
Filed: 1973-12-31
Abstract: 1414099 Friction clutches; clutch control TWIN DISC Inc 31 Dec 1973 [2 Jan 1973] 60262/73 Headings F2C and F2L An hydraulic actuator for a friction clutch in a marine transmission comprises a clutch engaging piston 10 which together with a piston 11, 12 forms a chamber 15 that is divided into two compartments 16, 17 by a freely axially slidable ring 18, the two compartments being supplied simultaneously with pressure liquid from separate pumps P, P1 through a valve 25 for full clutch engagement. In the event of failure of one of the pumps, the supply from the other pump is sufficient to maintain full clutch engagement. When the valve 25 is moved to the position shown in which it cuts the supply from the pumps P, P1 to the compartments 16, 17, pressure liquid may be supplied to the compartment 16 alone through a manually controlled modulating valve MV and a centrifugally controlled valve CV for slipping clutch engagement. The valve CV is carried by the clutch output shaft 8 and meters pressure liquid to the compartment 16 to control the slipping engagement of the clutch and maintain the speed of the output shaft 8 constant for a predetermined setting of the modulating valve MV. The valve MV supplies pressure liquid from the pump P to the valve CV at a pressure responsive to the setting of a manually adjusted control spool 52. By adjusting the pressure supplied to the valve CV, the speed at which the output shaft is maintained constant is correspondingly adjusted. The valves CV and MV may be of the type described in Specifications 1,133,698 and 1,310,625. When the valve 25 supplies both compartments 16, 17 for full clutch engagement, the pressure in the compartment 16 acts through a duct 93 on the lower end of the spool 72 of the valve CV to hold the latter closed. The compartments 16, 17 have bleed orifices 36, 37. The size of the orifices 36, 37 is such that, in the event of failure of both pumps P, P1, the centrifugal pressure in the compartments 16, 17 maintains the clutch engaged for 33 seconds. The shaft 8 contains diametrically opposed pairs of supply ducts 21, 21; 28, 28; 64, 64 to the compartments 16, 17 and valve CV, the pairs of ducts maintaining dynamic balance of the shaft 8. The pressure supplied by the pumps P, P1 is regulated by valves (33, 41), Fig. 1 (not shown) and the exhaust from the regulating valves is supplied through ducts (44, 45, 46, 47, 48, 8a, 8b, 8c) to cool and lubricate the clutch plates. The clutch may be a multi-disc clutch between a gas turbine engine and a ship's propeller.

Patent GB-769624-A (GB)
IPC: C06F1/08
Abstract: 769,624. Making matches. ZILVER, E. April 4, 1955 [April 7, 1954]. No. 9802/55. Glass 50. A splint-carrier for a match-making machine. comprises a rigid plate or plates to which is secured a resilient means which grips the splints presented through holes or spaces in the plate. In Fig. 2, the resilient means is of rubber or the like and is formed with holes 6 which register with larger flared holes 4, 5 in the top and bottom plates 1, 2. The plates 1, 2 are connected by rivets 7 passing through spacers 8 which at one end of the carrier, are recessed at 9 to accommodate a roller 10 on a pin 11. This roller, and the convex shape of the other end of the carrier, Fig. 5, prevent the carrier from sticking in its guides. In a modification, the bottom plate 2 is dispensed with, the upper plate being bent around at its ends to. hold a spacer 8 in which the roller 10 is accommodated. In another construction, the resilient grippers may consist of lengths of rubber tube, each registering with perforations in the plates 1, 2. In all cases, the plates may be of hard rubber vulcanized to the soft rubber grippers, and the shapes of the holes accord with the sections of the splints. In Fig. 5, the plates 1, 2 are replaced by strips 24 having intermediate spaces 25 through which the splints are presented to be gripped between transverse rubber or like strips 27. In Fig. 6, the rubber grippers are replaced by spring strips 29 or by coiled springs 30. In the first case, the splints presented through the top plate 1 (not shown) are held in the spaces between bent-out parts 33, 34 of the strips; and in the second case, the splints are held between the spring coils. The recesses at the ends of the sides of the carrier co-operate with driving- means for the carriers.

Patent GB-2038428-A (GB)
Title: Piston Rod Seal
IPC: F02G1/053
Filed: 1979-12-07
Abstract: Piston rod sealing means of the type in which oil is applied through a passage 16 to the low pressure side (5) of the seal and used to prevent escape of high pressure gas between the piston rod (6) surface and a surrounding surface of a plastic material gland (12) are improved by providing the gland (12) with a tubular extension (15) of slightly increasing inner diameter in the direction towards the high pressure side (4) of the seal. The gland (12) is forced against the piston rod surface by a spring (14) acting through a ring (13), but the tubular extension (15) is not influenced by the force on the gland (12). In use, as the rod reciprocates, the extension effects a pumping action to force back oil towards the low pressure side. <IMAGE>
