Patent GB-869590-A (GB)
Title: Improvements in or relating to control arrangements for use with marine or stationary engines
IPC: B63H21/22
Filed: 1959-05-28
Abstract: 869,590. Electric selective signalling systems. SHARP & CO. Ltd., and FLORY, H. E. May 28, 1959, No. 18233/59. Class 40 (1). [Also in Group XXIV] A control arrangement for a marine or stationary engine comprises a hand lever movable on either side of a neutral position to engage forward or reverse, further movement of the lever progressively opening the engine throttle or fuel control member. As shown, a crank roller 6 engages a slot 5, 5a in a gear lever 2 and a slot 8 in a throttle control lever 9. In the neutral position, the roller 6 is at the top of slots 5a, 8, and rotation of the crank in either direction moves the roller down the slots, rotating the lever 2 to engage forward or reverse until the roller reaches the bottom of slot 8 and the top of slot 5 which is triangular in shape. Further rotation of the crank moves lever 9 downwardly to open the throttle, gear lever 2 remaining stationary as the roller moves idly in slot 5. The crank is rotated by an electric motor (not shown) under the control of an electric seeking arrangement, comprising a receiver 22 and a transmitter 23. The receiver comprises a series of outer contacts (e.g. 46, 41, 47) connected to corresponding contacts of the transmitter, an inner ring 48 connected to the electric supply, and a wiper arm 30 driven by the electric motor which connects the ring 48 to a selected one of the outer contacts. The transmitter assembly comprises, besides the said contacts, arcuate contacts 31a, 31b rotatable by means of a hand lever (not shown) so as to bring a selected contact, such as the neutral contact 53, opposite the gap between the arcuate contacts. This energizes an appropriate one of two relays which completes a circuit to the electric motor which is driven in the appropriate direction to close the throttle and return the gear lever to neutral at the same time rotating the wiper arm 30 until it co-operates with the " dead " contact 41 and de-energizes the relay. If the crank should continue to rotate due to inertia, the wiper arm will engage a contact 29 energizing the second relay via contacts of the transmitter and the electric motor will be reversed so that the wiper arm will re-engage the dead contact. In a similar way subsequent movement of the hand lever will result in operation of the electric motor until the wiper arm contacts the " dead " contact, thus engaging forward or reverse and opening the throttle by a selected amount. If the wiper arm overshoots its end positions it engages a contact 44 or 45 directly connected to a relay so that the motor is reversed. Several transmitters may be employed to enable the engine to be controlled from a number of remote stations.

Abstract: 351,235. Switching systems for consuming devices. SIEMENS-SCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. June 17, 1930, No. 18538. Convention date, Jan. 18, 1929. Addition to 347,516. [Class 38 (iv).] The means by which a consumption resistance is switched in during the high-tariff period in an arrangement described in the parent Specification is automatically returned by the clock to the switched out position at the end of the high-tariff period. The clock mechanism 28 actuates a member 195, coupled to a member 193 controlled by a dead-centre spring 194, so as to rock the mercury switches 16 to the left to close the circuit of the consumption resistance 3, and to byepass the rebate meter 14, in the high-tariff period. By operating the hand-controlled element 203 to the left the closing of this circuit may be permitted. According to the invention the member 203 is returned to the position shown in the Figure by a spring 204 when the clock rocks the switches 16 to the right into the low-tariff position. The pin 1810 engages a cam 209 to hold the member 203 during the high-tariff period, but this cam is so shaped as to enable the consuming resistance 3 to be switched off at any time against the holding action of the pin 1810.

Abstract: 704,902. Compressors. RICARDO & CO., ENGINEERS (1927) Ltd., and RICARDO, H. R. July 16, 1952 [Aug. 8, 1951], No. 18655/51. Class 8 (1). A reciprocating compressor has a cylindrical valve member and housing arranged for relative rotation for controlling admission and delivery ports in their cooperating cylindrical walls, and also for relative axial movement for varying the points of opening of both the admission and delivery ports without changing their points of closing, said axial movement being effected automatically by variations in the relationship between the admission and delivery pressure. The compressor comprises a pair of cylinder blocks A, A<SP>1</SP> each having a plurality of parallel cylinders A<SP>2</SP> disposed around a rotary distributing valve K and containing double-acting pistons G connected in pairs by piston rods G' passing through elongated guides F in the ends of the cylinders and actuated by a wobble plate H<SP>1</SP>. The latter is journaled on bearings H<SP>2</SP> carried by a member H<SP>3</SP> secured to a main driving shaft H<SP>4</SP>. The piston rods each have a cylindrical housing G' for a rockable member G<SP>3</SP> bored to receive a pin H projecting from the wobble plate. One of the housings G<SP>4</SP> has end caps to prevent its member G' from sliding axially therein and so prevent the wobble plate from rotating; the other housings are open-ended to allow free transverse movement of their inner members. Combined inlet and discharge ports J are disposed at each end of the cylinders and cooperate with inlet ports K<SP>6</SP> K' and discharge ports K<SP>4</SP>, K<SP>5</SP> in the rotary valve. The inlet ports in each valve communicate permanently with an inlet passage L and the discharge ports with a discharge passage D'. The valves which are driven from the shaft H<SP>4</SP> are slidable axially thereon and are biased outwardly by springs M. If the discharge pressure in the passages D' increases, the valves are moved axially against their springs and the co-operating ports in the cylinders and the valves are so shaped that the opening of the ports is retarded and hence the discharge pressure from the cylinders is increased. The piston rods G<SP>1</SP> are a close sliding fit in the guides F which maintain the pistons G substantially out of contact with their cylinders. Annular grooves are provided on the pistons and on the surface of the rotary valves to form a labyrinth packing. An annular cham- .ber F<SP>6</SP> is provided in each of the guides F to which lubricant-laden air has access through passages F<SP>5</SP>. Balancing members N<SP>2</SP> are provided on the main shaft to counteract the effect of the wobble plate. Specifications 704,903 and 704,935 are referred to.
