Abstract: 558,992. Hydraulic clutches. FREDERICKSON, C. E. July 27, 1942, No. 10495. [Class 69 (ii)] A hydraulic clutch for transmitting motion at a variable ratio comprises a driven rotor comprising a casing 10 filled with oil and connected to the flange 9 of the driving shaft 7, a steel inclined track 17 being secured in a recess 16 in the casing 10 to control a wobbler ring 39 connected by connecting-rods 57 and universal joints to pistons 52 which may reciprocate in cylinders 51 fitted to an inner rotary member 31 formed with a sleeve 27 to which the shaft 8 is splined. The wobbler plate is controlled by a ball raceway 86 interposed between a groove in the track 17 and a steel ring 41, and the connecting-rods 57 are secured to the pistons and the wobbler ring by means of plugs 53, 44 screwed into sockets having spherical bearing segments. The spherical head 62, Fig. 8, is secured to the rod 57 by means of a screw 59 and a riveted head 61 on a shank 60. The plugs 44, 53 may be held from unscrewing by means of latch springs engaging grooves in the plugs. The cylinders 51 are formed with inlets 63 and outlets 64 for the liquid, and the outlets 64 are controlled by a valve 73 which is slidable inside the member 31 owing to a connection of its stem 75 with a sliding sleeve 80 operated by a lever 83, which operates a fork 82 and is held in its extreme positions by a spring catch. In the one extreme position shown the liquid can pass freely out of the cylinders 51 which are in compression and freely into the other cylinders which are in suction and in this case no motion is transmitted. In the other extreme position the valve 73 closes the ports 64 and the members 12, 31 are hydraulically locked and a direct drive results. In intermediate positions a variable transmission ratio takes place depending upon the position of the lever 83. The wobbler is mounted for universal movement about pivots 36, 38, and the pivot 36 is mounted in bearing blocks 34 in a hub 32 of the member 31 in which is a pressurerelieving spring 35. The pressure in the member 31 may be increased if it falls below that in the rotor 10 by liquid admitted through valves to ports 65, and liquid can pass into the cylinders through valved ports 67. Excess fluid pressure in member 31 is relieved by a valve 77 at the end of duct 76. The whole mechanism is fitted in a casing 85, and the rotating parts are mounted in ball bearings 4, 5, 20, 26, 6 and oil seals 29, 72 are provided. The casing 10 is formed with cooling fins, and with a starting gear 13.

Abstract: 838,895. Vertical steam boilers. MARCUS, I. D. April 2, 1958 [April 9, 1957], No. 10704/58. Class 123(2) A vertical boiler comprises a box-like casing surmounted by a smoke hood 8 having a stack outlet 14, the casing being divided internally by a crown sheet 15 into a lower furnace chamber 17 and an upper steam and water chamber 16. Vertical flues 35 extend from the chamber 17 through the chamber 16 into the hood 8. The chamber 16 is divided into three sections by partitions 28, 29 to provide a centre steam section 33 flanked by water sections 31, 32. The upper and lower edges of the partitions 28, 29 which extend from end to end of the casing are spaced inwardly from the side walls to allow for the circulation of the working medium. In operation, feedwater is pumped into the boiler through pipes 41, 42 and passes under the baffles 28, 29 into the steam section 33 wherein it is partially evaporated, the steam-water mixture rising through the restricted centre section 30. Steam separates in the enlarged space above the partitions 28, 29 and discharges through outlet pipes to the point of use. Water returns to the water spaces 21, 32, over the upper edges of the baffles 28, 29. By maintaining a low water level in the boiler superheated steam can be produced whilst if saturated or wet steam is required the level is suitably increased. Removable baffles can be inserted in the gas flues to increase the amount of heat absorbed.

Title: Improvements in or relating to fluid flow limiting device
IPC: G05D7/01
Filed: 1955-04-15
Abstract: 793,798. Fluid-pressure servomotor control systems; valves. GARRETT CORPORATION. April 15, 1955 [April 28, 1954], No. 10887/55. Class 135. A fluid flow limiting device, more especially for controlling the outlet from an expansion turbine which feeds a pressurized aircraft cabin, comprises a valve in the form of a resilient, helical tube 61 situated at the outlet from the turbine 11 and controlling the escape of fluid through outlets 35, the tube being compressed to close the outlets by a diaphragm 53 under the control of a pilot valve 77 which is actuated by a pressure-responsive diaphragm 73 subject on its upper surface to pressure at the throat of a venturi 42 and on its lower surface to a reference pressure derived from a point upstream of a venturi 30 in a branch passage 25 and passing through a valve 104 which is actuated by an evacuated bellows 108 so as to compensate for variations of density of the controlled fluid. The pilot valve 77 controls the supply to a chamber 52, which has a restricted outlet 101, of fluid tapped from the inlet 12 to the turbine and pressure-controlled by a valve 116. Flow in the passage 25 is also controlled by a butterfly valve 28 which is actuated by a diaphragm 138 under the control of a pilot valve 128 which is operated by a diaphragm 12 0  subject on its upper surface to pressure at the throat of the venturi 30 and on its lower surface to the pressure from the valve 104. An adjustable restriction 126 interconnects the two sides of diaphragm 120. The arrangement is such that an increased flow through the branch 25 causes the butterfly valve 28 to be moved towards closure whilst an increased flow in the passage 18 causes the helical valve 61 to open to spill fluid through the outlets 35. In a modification, the reference pressure which acts below the diaphragm 73 is taken from a point upstream of the throat of the venturi 42.

Title: Improvements in or relating to code error detection arrangements
Inventor: REED JOHN
IPC: H04L1/00
Filed: 1959-03-31
Abstract: 861,333. Code telegraphy. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. Oct. 1, 1959 [March 31, 1959], No. 10923/59. Class 40(3) An arrangement for detecting an error in code combinations of elements having a predetermined relationship between the elements comprises a number of bistable switchable devices corresponding to the number of acceptable code combinations each device being appropriate to a different acceptable code combination and capable of being switched to one predetermined state, and means responsive to the pulses indicative of the nature and relationship of a received code combination for switching selected ones of the said devices to the other predetermined state, and the arrangement is such that all the devices not corresponding to the said code combination are so switched and error-indicating means responds to the absence of said one predetermined state in any one of the said devices for indicating an error. In one arrangement, Fig. 3, arranged to detect an error in a 3-unit combination of marks and spaces having only one mark, one of the bistable devices X, Y, Z is not switched when an acceptable code combination is received. For example, the reception of the combination M1S2S3 leaves the device Z unswitched so that the application of a sensing pulse to the three devices X, Y, Z produces a pulse from the device Z and the error-indicating device is not brought into operation. In the arrangement, Fig. 4, for operation in response to 3-unit code combinations, having solely one marking element, the output from the receiver 2 is applied to an arrangement 3 of cores which have been restored to a predetermined "O" condition by a pulse over a connection 5 from a pulse generator 4. Subsequently a sensing pulse is applied from the generator 4 over conductor 6, and if the received code combination is without error, a pulse is applied over the appropriate line a, b, c, to a gate and pulse-shaper 7 opened by the sensing pulse on the conductor 6. If the received code combination is without error it is passed from the gate device 7 over the lines a<SP>1</SP>, b<SP>1</SP>, c' to a receiver device 14 which may be a teleprinter. Prior to the sensing pulse over connection 6, a pulse is passed from a generator 9 to set a detecting device 8, constituted by a ferro-magnetic core, into the zero condition. A subsequent sensing pulse from the generator 9 over a conductor 11 produces a pulse from the device 8 if an impulse has not been received from the gate device 7, i.e. the occurrence of an error, and this pulse passes through a gate 12 opened by the sensing pulse over the conductor 11 to operate an error indicating device 13. If no error has occurred, the device 8 is set to the "1" condition by the pulse from the device 7, and a pulse is not generated in response to the sensing pulse over conductor 11. The system described can be expanded to be used in connection with a 7-unit equal-ratio code having three marks and four spaces.
