Title: Apparatus for measuring rates of urine flow electrically
IPC: A61B5/20
Filed: 1976-01-05
Abstract: 1527671 Measuring fluid flow-rate RICHARD WOLF GmbH 5 Jan 1976 [3 Jan 1975] 00237/76 Heading G1N The rate of flow of urine into a measuring vessel 24 is determined by differentiation of the signal from a capacitor measuring the level of the urine 30 in the vessel. The capacitor has co-axial electrodes 27, 28 of which an inner electrode 28 is insulated from an outer electrode 27 and from the urine by a coating 29 of PTFE. A measuring circuit uses a pulse generator 13 providing pulses 13a of constant repetition frequency to a monostable circuit 14 wherein the pulse-durations are modulated as a function of the capacitance of the level-measuring capacitor 15. The resultant pulses 14a are fed to a sawtooth generator 16 providing a pulse-amplitude-modulated signal 16a. This is rectified and smoothed 18, 19 to provide a direct voltage proportional to instantaneous urine volume. The direct voltage is differentiated in circuit 21 and the resulting flow-representing signal is indicated 22 and recorded 23. Alternatively, Fig. 1 (not shown), the measuring capacitor (1) is energized with a constant amplitude A.C. by oscillator (2), the resulting current producing via transformer (3), amplifier (4), rectifier (7) and measuring instrument (8) an indication of volume which is differentiated at (10) to provide the flow-rate signal.

Abstract: 1,036,377. Fluid-pressure servomotor systems. A. S. THOMAS THS SABROE & CO. Jan 5,1965 [June 19,1964],No.383/65. Heading G3P. A valve 12 for automatically regulating the performance of a multi-cylinder compressor is actuated in a stepwise manner by a piston 24 inserted in the valve and acted upon at 15 by the suction pressure of the compressor and at 14 by a medium pressure greater than the suction pressure, the valve having ribs 45 and the piston recesses 46 for co-operation with members, such as balls 41, 42, which are stationary in relation to the valve housing. The balls are mounted in a cage 43 and the piston 24 which is loaded by a spring 36, is connected to the valve by a pair of springs 38, 39. A bellows 23 subjected through a line 19 to the suction pressure of the compressor regulates the position of a needle valve 22 controlling the pressure in a chamber 14 connected to a medium pressure line 18 and hence the position of the valve. As the latter moves to the right it isolates servomotors 32-... 35 in succession from the medium pressure line rendering suction valves of the compressor inoperative. The valve 22 may be controlled by the temperature in a refrigerated compartment and the medium pressure may be obtained from the lubricating oil pump of the compressor.

Title: Improvements in thread rolling tools
IPC: B21H3/04
Filed: 1954-01-07
Abstract: 753,845. Rolling. LANDIS MACHINE CO. Jan. 7, 1954 [March 30, 1953; Sept. 16, 1953], No. 468/54. Class 83 (4). In a device for rolling screw threads by means of an intergeared pair of threading rolls 20, 22, Fig. 1, fed laterally on to the workpiece the diameter of each roll is corrected to allow for the relative movement of the workpiece over the roll periphery resulting from the lateral feed so that both rolls may rotate at the same speed without imposing stresses on the work. With clockwise rotating rolls 20, 22 in a holder 24 attached to the tool slide of an automatic screw machine, the diameter of the upper roll is reduced and that of the lower roll increased above or below an integral multiple of the work diameter by an amount which compensates for the movement of the point of contact over the roll periphery from the initial point of engagement to the fully engaged position. The rolls are mounted in frame members 40, 42 pivoted on a shaft 30, Fig. 3, and bearing 38 in the holder 24 and adjustably held at the required distance apart by a strap 50 with slotted recesses for screws 54 in the frame members. Wedge blocks 58, 66 adjusted by a screw 62 permit fine adjustment of the frame members. Shafts 78, Fig. 5, for the rolls are mounted at one end in interchangeable bearings 80 with recesses 90 at different eccentricities for setting the rolls at the required skew angles. The rolls have helix angles determined by the corrected diameter and are skewed so that for any given thread pitch to be rolled the thread on the outer periphery of the rolls is brought parallel to the thread at the main diameter of the work. The bearings 80 are held against axial movement by screws 84 (not shown) engaging circumferential grooves 82 and are held against rotation by pins 88. The shafts 78 are located at the opposite ends in bearings 92 having slightly eccentric recesses 94, which permit adjustment of the distance between the shafts 78 to compensate for wear. Each bearing is located in either of two positions by a screw 98. The shafts 78 are held against rotation by flats 104 engaging correspondingly shaped slots in the frames 40, 42. The rolls 20, 22 are freely rotatable on the shafts 78 and coupled through dogs 110, 112 to gears 106 on the shafts 78. The gears 106, Fig. 10, engage idler gears 114, 116 so that the rolls are interconnected to rotate at the same speed. In a modification the gears 106 are replaced by gears 138, Figs. 13, 14, having projecting cylindrical spring wires 144 adapted to engage in the dog 112 of the rolls to permit flexing so that on withdrawal of the work from the rolls undue stresses resulting from the relative movement are prevented.

IPC: H01M6/24
Filed: 1917-01-17
Abstract: 111,383. Henry, H. D. Jan. 17, 1917. Electrodes; amalgamating.-Zinc is subjected to a preliminary treatment before amalgamation, which consists in placing it in an acid electrolyte with a fully charged lead peroxide plate and discharging the combination through a resistance. The zinc is then removed, washed, dried, and amalgamated by treatment with mercury or one of its salts such as the sulphate. In order further to prevent wasting of the zinc electrode in a battery consisting of zinc, lead peroxide, and an acid, the zinc is so arranged that the area exposed to the electrolyte is constant and about one fortieth of the area of the lead oxide plate. This may be obtained by enclosing the whole plate in a vulcanite &c. envelope with only the desired area of zinc exposed to the acid. Or the zinc may be in the form of a block covered except for a small portion with rubber &c. In order to allow the full current to pass as the electrolyte becomes weaker, the zinc may be slightly tapered so that the exposed area gradually increases as the zinc dissolves.

Abstract: The system uses a modified subscriber station to act as a simulated or emulated base station. This emulated base station essentially differs from the subscriber station only in being able to initiate the synchronization process, whereas the subscriber unit only acts to scan the RF signals sent out by the emulated base station until it finds the frequency and slot assigned to it. - The signal received from one station is separated into high band and low band energy frequencies. The high band energy output is substracted from the low band energy output to obtain a resultant signal, which is stripped of its sign determine only the amplitude. The stripped signal is accentuated while substantially filtering out noise, and fed to a voltage controlled crystal oscillator (VCXO) which provides the timing at the other station.
