Abstract: 1,166,730. Controlling vehicles. P. PATIN. 30 June, 1967 [30 Aug., 1966], No. 30317/67. Heading B7H. [Also in Divisions F1, F2 and G3] Hydraulic transmission for a vehicle comprises a centrifugal pump 2 driven by an I.C. or gas turbine engine 1 and connected to at least one positive displacement motor 3 by supply and return lines 4, 5, the combination of centrifugal pump and positive displacement motor giving an inherently self-regulating transmission, and has a Venturi 26 in the return line 5, the Venturi throat and entry pressures being applied to opposite sides of the diaphragm 37 of a diaphragm-operated servo valve 21 which controls servo motors 22, 24 actuating the engine throttle and an output brake respectively, to maintain a selected motor 3 speed. In valve 21, a piston 29 secured to the diaphragm 37 is slidable in a sleeve 28 pivoted at 31 to a driver's pedal 32 and slidable in a cylinder 27. A wall 40 formed on the cylinder 27 is shaped so that movement of the piston 29 is a linear function of the fluid flow rate through the Venturi, due to the progressive engagement of the wall by the diaphragm as the latter moves leftwards. Cylinder ports 47, 48, connected to the throttle and brake servo-motors respectively, are aligned with respective ports 45, 46 in the sleeve 28. Ports 43, 44 in the piston 29 are connected via a passage 41, valve chamber 42 and a line 39, to the Venturi throat. Movement of the pedal 32 to increase or decrease speed slides sleeve 28 to align ports 43, 45 or 44, 46 to admit fluid to the throttle or brake servo motor. When the speed of motor 3 has reached the selected value, the pressures on diaphragm 37 move the piston 29 to close the ports. If the speed wanders, piston 29 is moved to cause a correcting servo action.

Title: Improvements in or relating to position plotting apparatus for use with radar or other positional information systems
Inventor: PARRISH JOSEPH REGINALD
IPC: G01S1/02
Filed: 1956-10-09
Abstract: 878,901. Radar. H. N. ELECTRICAL SUPPLIES Ltd. Nov. 12, 1957 [Oct. 9, 1956], No. 30748/56. Class 40(7) [Also in Groups XIX and XX] Apparatus for recording the course of an object shown on a radar screen relative to the radar and recording apparatus which may itself be moving (e.g. on a ship) and have its own course plotted consists of a casing A containing a movable recording sheet mounted on rollers 1 and a movable printer capable of effecting a series of elongated prints on the sheet at points corresponding to the position of the object from time to time as indicated on the radar screen. The sheet is driven from one roller to the other and a carriage 2 mounted on rails 4 is driven laterally underneath it in such a way that the combined movement causes the central point of the carriage, where there is a printing head, to follow, relative to the paper, a track corresponding to the course of the ship or the like carrying the apparatus. Movement of sheet and carriage are conveniently effected by the output of a computor fed manually or automatically with speed, course, and the direction the paper movement is to represent. Print operation may be effected at timed intervals and, when movement is small, a second print prevented until the printer is clear of the first print made. The sheet is sufficiently transparent for the prints to be seen when lit from behind and viewed through a glass panel over the sheet. To record the course of a radar detected object a rotatable arm 18 is mounted on the carriage and carries a printing head adjustable in position along the arm. Manually adjustable range and bearing markers are provided on the radar plan position indicator and the controls for these are coupled to the recorder to move the printer along the arm in correspondence with range and to rotate the arm in correspondence with bearing. When the markers are aligned with the representation of the object on the P.P.I. a button may be pressed to operate the printer to mark the corresponding position on the sheet in the recorder. The central printing head may be arranged to print at the same time if required. Chisel-shaped printers are used to produce a record of the kind shown in Fig. 4. Here 70 is the plot of the observing ship's track, 71 is the record of an observed ship on a collision course, and 72 the record of a ship that will pass astern. It should be noted that the line indications produced by the chisel printer are parallel when an observed ship is on a collision course but not otherwise. Time markings may be made on the record opposite the indications of the ship's own position.
