Title: Improvements in or relating to control devices for marine propulsion
IPC: F16H3/00
Filed: 1963-06-28
Abstract: 969,189. Reverse-gear control. ZAHNRADFABRIK FRIEDRICHSHAFEN A.G. June 28, 1963 [July 14, 1962], No. 25833/63. Heading F2D. Means reducing the pressure applied to direction-establishing hydraulically-actuated clutches during drive reversal in a water craft reversing gear, comprises a regulator valve 16 in a line 17 between a first pump and a Forward- Neutral-Reverse control valve 27, a doubleacting cylinder 43 having a spring-centred piston 44 connected, by a rod 24, to the valve 16 to vary the loading of the loading spring 25 of the latter, a second pump belt-driven by the propeller shaft 1 and feeding a line 14 or 15 depending on pump rotational direction, and a second control valve 33 connected, by a rod 42, to the valve 27 and arranged to connect the lines 14, 15 to opposite chambers 47, 48 of the cylinder 43. On leftward movement of the valve 27, the valve 33 connects the line 14 to the chamber 47 of the cylinder 43 so that increasing pressure in the line 14 due to increasing propeller shaft speed leftwardly shifts a piston 44 to increase the loading of the regulator valve spring and increase the clutch pressure. On reversal, rightward movement of the valve 27 first effects stoppage of the propeller shaft with the valve 33 exhausting the chamber 47 so that the piston 44 is centred and the loading of the spring 25 and, hence, the clutch pressure are reduced. On completion of the rightward movement of the valve 27 the appropriate clutch is engaged for rotation of the propeller shaft in the reverse direction, and increasing pressure in the line 15 through the valve 33 rightwardly shifts the piston 44 to increase the clutch pressure. The pump 3 suction and delivery lines are respectively provided with non-return valves 7, 8 and relief valves 9, 10 the latter allowing a sufficiently high pressure to displace the piston 44 against its spring-centring. The valve 27 may be manually controlled. The valves 9, 10 may relieve to a transmission lubricating line.

Filed: 1974-06-12
Abstract: 1479718 Data processing system H B DITMORE 12 June 1974 [2 Aug 1973] 25997/74 Headings G4M and G4R A data processing system has sets of class cards or films and object cards, or films, the class cards having markings relating to statistical data about the class and the object card acting as a mask to examine selected parts of the data. The class cards may, for instance, relate to diseases and carry statistical information relating to symptoms associated with the diseases, e.g. markings in specific locations on a card or film have openings 24, 28, 32 the area of which indicates the percentage of people known to have had the disease who have had the particular symptom and further openings 26, 30, 34 indicating the percentage of people who have not had the symptom. Light passing through the class card or film may pass through further openings which modify the values to produce a logarithmic variation or the openings in the class card or film may themselves be shaped to provide a logarithmic variation. A patient receives a card having areas aligning with the class card markings and removes selected areas according to whether he has the symptom or not. Light passing through the class and object card is sensed and decoded to indicate the probability the patient has the disease. The symptom and answer cards may have markings arranged on a branching system (Fig. 8) with a YES or NO working position depending on the response to a prior symptom in the chain. The cards may be used for game theory, to calculate statistical probabilities, for information theory or for character or picture recognition. In the latter case patterns are produced using Fourier or Fraunhofer transformations and the pattern is scanned to produce a yes, no response to the question, "is this area dark?"  The results produced are compared with class cards carrying data indicating the probability of dark spots at the locations for a picture or character.

Title: Improvements in or relating to ice detectors
IPC: G08B19/02
Filed: 1964-06-25
Abstract: 1,049,109. Icing detectors. ROSEMOUNT ENGINEERING CO. June 25, 1964 [Nov. 19, 1963], No. 26387/64. Heading B7W. [Also in Divisions G1 and G3] An icing detector has a probe comprising a mandrel of insulating material, heating means automatically controlled to maintain the temperature of the probe above the freezing point of water, and means for detecting and indicating the presence of water on the probe. In one embodiment (Fig. 1, not shown), a pair 16, 17 of wires are wound on a mandrel 15 and are connected via transformers, 23, 24 (Fig. 3, not shown) to opposite sides of a bridge circuit 25 arranged to be balanced when the probe temperature is 2 C. The output of the bridge circuit is fed to a detector 31 which, when the bridge imbalance (due to resistance variation with temperature) is in the sense of reduced probe temperature, transmits a signal to a power amplifier 33 which transmits power by leads 35, 36 to the bridge circuit, and hence the wires 16, 17 to heat the probe, and also generates a signal in the secondary winding 49 of a transformer 42. A D.C. voltage is applied by a source 44 between the wires 16, 17, and when water is present on the probe current flows between the wires and through a relay 45 or equivalent electronic means closing a switch 47 and allowing any signal from the transformer 49 to be transmitted to an indicator, or to suitable de-icing equipment. In another embodiment, a pair of wires wound round the mandrel are used solely for water detection, a separate temperature sending wire is used, and a heating element is embedded in the mandrel. The temperature sensing wire 66 (Fig. 6, not shown) is connected, via a transformer 68, in a bridge circuit 70, the output of which is fed to a detector 73, which, when the probe temperature falls, supplies a signal to an amplifier 75 connected to the heating element 62 and a transformer 80. The water detecting wires 63, 64 are connected to a D.C. source 90 and a relay 87, so that when water is present, current flows between them and the relay operates to close a switch 86, and any signal from the transformer 80 is transmitted via terminals 84, 85, to an indicator.

Abstract: 447,468. Heating by circulation of fluids. MUSGRAVE, J. L., LEWIS, D. G., and CRITTALL & CO., Ltd., R., 43, Bloomsbury Square, London. Sept. 19, 1934, No. 26927. [Class 64 (ii)] [See also Group XXIX] In a hot-water circulating system, an electrically driven time-switch A first opens the circuit a<1> closing the main valve F or stopping the pump, then closes circuit a<2> closing the circuits to the solenoid valves B, D, E, next closes circuit a<1> restoring the circulation, and then opens circuit a<2> breaking the solenoid valve circuits to save current. The cycle is repeated at predetermined intervals. Should the temperature of a room be above the setting of its thermostat H, its valve B during the period of interruption of its electric supply would be retained closed by the pressure of the water. Should the temperature be below the thermostat setting, the electric circuit would be open at the thermostat, and the valve B, having fallen open on the previous closure of the main valve F or stoppage of the pump, will remain open until the thermostat is in a closed position at the operation of a cycle. The second step, closing the valvecircuits, may be repeated before proceeding to the third step, restoring the circulation.
