Title: Improvements in electric meters
IPC: G01F1/50
Filed: 1925-12-07
Abstract: 267,583. Rogers, F. H., (Republic Flow Meters Co.). Dec. 7, 1925. Liquid-level pressure gauges.-The quantity to be measured, for instance the drop of pressure due to flow of a fluid through an orifice 18, causes variation of a mercury column 20 which varies a resistance 11. This is connected across an alternating current supply in series with coils 6, 7, which co-operate with a highly inductive pressure coil 1 to rotate a conducting disc 8. The edge of this disc is so shaped that a variable portion is acted on by the poles 12, 13 of a second magnetic system 2 wound with coils 4, 5, which are connected across the alternating current supply in series with a resistance 10, which may be varied by means of a mercury column 22 in accordance with the pressure or temperature of the fluid being metered. The coils 4, 5, in conjunction with the pressure coil 1, exert a torque on the disc 8 in a direction opposite to that due to the coils 6, 7, and varying according to the position of the disc, which takes up a position of rest in which the opposing torques are equal. The resistances 10, 11 may be interchanged. Variation in the supply pressure affects both torques equally, and consequently does not affect the reading. The instrument may be calibrated to indicate directly the velocity of flow of a fluid, corrected or not for temperature or pressure, or it may indicate at a distance the reading of a mercury thermometer or of a resistance thermometer, or the height of a liquid or pressure of a gas in a tank. The instrument may be arranged to record on a clock-driven chart.

Title: Improvements in indicating means for radio tuning devices
IPC: H03J1/02
Filed: 1950-12-19
Abstract: 692,054. Indicating-apparatus. WESTOVER, C. D. Dec. 19, 1950, No. 30942/50. Class 106 (iv). [Also in Group XL (c)] Indicating means suitable for use with radio tuning arrangements comprises a first dial bearing a spiral scale and a second masking dial having a spiral slot, and means for rotating the dials differentially so that the slot and scale coincide along a radial line. In Figs. 1 and 4, a window 30 is provided in plate 31 so that part of a spiral on disc 2, having approximately four revolutions, is visible through part of a spiral slot of approximately one revolution in disc 1. Rotation of shaft 40 by knob 4 rotates disc 2 through gears 41, 42, 45, 24, and rotates disc 1 by means of gears and arm 13 which engages a projection on disc 1. Disc 2 is arranged to rotate approximately four times for one revolution of disc 1, the viewed scale travelling up window 30 as knob 4 is rotated. The axis of rotation of disc 2 corresponds with the axis of shaft 40, and is slightly off-set from the line through index 3. Disc 1 is rotated about a bushing 51, the axis of which is off-set still further from the index line 3. This arrangement improves the correspondence between the slot and the scale in the viewing window and prevents a slanting effect.

Title: Improvements in rotary-piston pumps
IPC: F04C2/10
Filed: 1965-07-21
Abstract: 1,074,170. Rotary pumps and motors. J.H.P. CAMPBELL. July 21, 1965 [Sept. 24, 1964; Nov. 3, 1964], No.31035/65. Heading F1F. In a rotary-piston pump, or motor, a piston or rotor (3), Figs. 1 and 3 (not shown), revolves in a planetary manner within a stationary housing (4) and has five apex edges (2), which sequentially engage with four lobes (5) in the inner peripheralsurface of the housing to effect displacement of a fluid from a port (6) in one of said lobes to a port (7) in an adjacent lobe, channels (12) being formed in said surface between adjacent lobes except in the region of the ports. The planetary motion of the piston is controlled by gearing (16-20) situated externally of transverse walls (21, 22) in the housing. The gearing includes externally-toothed rings (19, 20) fixed to said walls and meshing with internally-toothed wheels (16, 17) attached to a shaft (9) carrying the piston, the ends of said shaft being rotatably and eccentrically mounted in wheels (25, 26) supported by coaxial rotatable shafts (10, 11). The shaft (10) is connected to driving means. Apertures (30, 31) in the walls (21, 22) may be sealed by rotatable discs. Counter-weights (25, 26) are attached to the wheels (25, 26) to effect balancing of the rotatable parts. In modifications, Figs. 4 and 5 (not shown), the piston has either three or four apex edges, the housing having lobes in its inner peripheral surface, which number one less than the apex edges. Alternatively, the planetary motion of the piston is controlled by an internallytoothed gear-wheel (62), Figs. 6 and 7 (not shown), which meshes with an externally-toothed ring (63) fixed to the housing and is attached to a shaft (59) carrying the piston (51), said shaft being rotatably and eccentrically mounted on a wheel (60) driven by a pulley (61) fixed thereon.

Title: Aerodynamic surface control feel augmenation system
IPC: G05D1/00
Filed: 1976-07-26
Abstract: 1516232 Fluid-pressure servomotor systems UNITED TECHNOLOGIES CORP 26 July 1976 [4 Aug 1975] 31063/76 Heading G3P An aircraft control surface positioning system, for example controlling collective pitch in a helicopter rotor 2, comprises a control lever 4 which when moved acts on a mechanical linkage 5 to actuate a pilot valve 22 and supply fluid to displace a piston 7 connected to position the control surface and also connected to the mechanical linkage 5 so as to restore the pilot valve 22 to its inactive position, an auxiliary valve 68 responsive to a signal, from a sensor 54, indicative of aero-  dynamic loading of the control surface, and means, such as a spring 40, connected to the linkage 5 to apply a force to the linkage 5 and hence to the control lever 4 when the piston moves on actuation by the valve 68 in response to the load signal. The signal from load sensor 54 is acted on by a function generator amplifier 60 to produce a signal when the load exceeds about 1/3 of the maximum permitted load, the value of this signal influencing the position of valve 68 and hence the pressure differential applied to the spool of the valve 22, causing it to move upwardly (as shown) and the piston 7 to move downwardly. This movement causes a force dependent on the constant of the spring 40 on the control lever 4, which must be opposed by the pilot (so that the movement of the piston 8 instead of moving the control lever 4 causes a force to be applied to the valve 22 in opposition to the pressure differential) if collective pitch is to be maintained. Measure also provided for maintaining a selected position of the control lever 4; a signal from potentiometer wiper 80 indicating the position of the lever 4 is fed via summing junctions 83 and line 85, amplified and added to the load signal to control the valve 68. If push button 93 on the control lever 4 is depressed, switch 90 is closed and integrator 92 produces a signal equal to that from the wiper 80, so that the signal on line 85 is zero; when the button 93 is released the integrator 92 continues to produce the same signal, so that if the lever 4 moves a signal is produced on line 85 to actuate the valve 68 and the valve 22 to act via the mechanical linkage to restore the selected position of the control lever 4.

Title: A Process for the Manufacture of Bituminous Layers and Plates Reinforced with Synthetic Threads
IPC: D06N5/00
Filed: 1968-06-28
Abstract: 1,179,376. Bitumastic laminates. ALGEMENE KUNSTZIJDE UNIE N.V. 28 June, 1968 [29 June, 1967], No. 31077/68. Heading B5N. [Also in Divisions B2 and E1] In a process for the manufacture of bituminous layers and plates reinforced with threads of synthetic linear polycondensation products the adhesion between the bitumen and the threads is improved by the use of a composition comprising tall resin. The threads are preferably of a relatively high denier such as 1000 or higher and a filament denier of from 3. The threads may be in the form of fabrics which may be knitted or woven, or bonded or non- bonded fibres. The threads may be twisted or untwisted continuous multi-filament yarns, monofilaments, spun yarns or fibres. The polycondensation product may be polyethylene terephthalate or polyamides obtained from lactams, such as caprolactam, or from diamines and dicarboxylic acids, such as hexamethylene diamine and adipic acid. In an exemplified process 7À25% of bitumen of penetration value 67 was mixed at 170‹Œ 5‹ C. with 45% of road metal, 39À75% of sand and 8% of a mediumgrade filler and compressed into tiles at 150‹ Œ 5‹ C. After cooling tall resin was sprinkled on the tiles and polyethylene terephthalate yarns stretched over the tiles at 2À5 cm. intervals. A top layer of the same asphalt mass was pressed on to the tiles at 145‹ Œ 5‹ C.

[Class 75 (iv)] [Also in Groups XX and XL] Apparatus for the production of photographic contact and reflex copies by artificial light comprises a main source of radiation and an auxiliary device which provides radiation not comprised in the direct emission of the main source. A mercury vapour lamp 1 and two electric glow lamps 2 are provided in a box-like casing 3 which is closed by a glass or quartz plate 4. The original 5 and the copying paper 6 are laid on the glass plate. The sensitive paper may be of the silver bromide type or the diazo type but must in each case be sensitive to light of long wave length. The lamps are connected to the source through a change-over switch and variable resistances so that the amounts of short wave light and long wave light can be adjusted. A short wave light source may be used alone and in this case a screen of luminescent material is applied to the glass or quartz plate 4 in the form of a line, stripe, grain, cross or surface screen. The luminescent screen may also be placed in front of the source of radiation and may be of convex or concave shape. It may also be used as a reflector behind the source.

Abstract: 1,060,760. Photo-electric position determination. J. HEIDENHAIN. Aug. 4, 1964 [Aug. 1, 1963], No.31579/64. Heading G1A. Apparatus for determining the position of an element 2, carrying a double set of parallel rulings as shown in Fig. 2 comprises a ruled scale 1 placed parallel to the element 2 and through which light is directed on to the element from a source and lens system. The light beams passing through the scale 1 and the upper and lower rulings of element 2 respectively are directed by lenses 4 and 3 to separate photodiodes P2 and P1. Amplifiers V 2  and V 1  block the D. C. component of the detector outputs and feed the amplified fundamental sine wave component (if any), to the stator windings of two motors M1 and M2. Motor M1 is a 20 pole motor and drives a mechanical counter Kl whilst M1 has only 2 poles and drives fine position indicator K2. When element 2 moves the output signals developed cause motor M1 to rotate in the appropriate direction so that the counter K1 is set to indicate the new position. If the movement is slow motor M2 will also rotate, at ten times the regular velocity, but if it is faster than the motor can follow it will oscillate, eventually taking up the correct position in either case to give the correct fine position reading.
