Title: System for reciprocally driving a structural element
Inventor: SKEHAN B J
IPC: G05D3/14
Filed: 1970-07-03
Abstract: 1317932 Automatic control of oscillations HUGHES AIRCRAFT CO 3 July 1970 [24 July 1969] 32448/70 Heading G3R [Also in Division H2] A system for reciprocally driving a member through a defined scan angle comprises a motor 22 coupled to the member (a reflector 10) and energized in accordance with the difference between an actual instantaneous position signal and a reference signal of triangular waveform, produced by means responsive to the position signal. The motor is a "torque motor" whose acceleration is proportional to current input and this is described as having a "double integration" effect. The reference voltage is produced by an integrator 88 which is switched between a steadily increasing and a steadily decreasing output voltage by the signal from the position pick-off and this determines the limits of the scan. The pick-off is of selsyn type energized from an oscillator 34; its output is passed through a phase detector 38 and a filter 40 which removes the oscillator component. The signal at C is thus a D.C. voltage representative of instantaneous angular position and this is fed to a summing junction 46 and to an impedance network 56. This is switchable between two values, for wide and narrow scan angles respectively. Its output is connected to a pair of differential amplifiers 72, 74, on the other inputs to which are connected reference voltages which determine the scan angle, since when the angle is such that the reference is exceeded the amplifiers cause a flip-flop 80 to change over. The flip-flop is connected to an operational amplifier 82 which thus produces either a negative or a positive output voltage which, via the integrator 86, produces the sawtooth position reference waveform at the junction 46 where it is compared with the angular position voltage from point C. The resulting error signal is given a phase lead to compensate for the lag inherent in filter 40 and controls a power amplifier 50 energizing the motor 22. To compensate for variations in the magnitude of the output of oscillator 34 this output is also supplied to the integrator 86.

Title: Improvements relating to stereophonic sound transmission systems
Inventor: FRANKLIN KENNETH VINCENT
IPC: H04H20/88
Filed: 1958-10-11
Abstract: 931,422. Stereophonic systems. ELECTRIC & MUSICAL INDUSTRIES Ltd. Oct. 12, 1959 [Oct. 11, 1958; Nov. 8, 1958], Nos. 32522/58 and 35920/58. Class 40 (4). [Also in Group XL (c)] In a stereophonic system two directional signals VL and VR derived from sound are linearly combined to form two signals A and B each of which is compatible (viz. such that A and B are never zero for any non-negative values of VL and VR, excluding the case where VL and VR are both zero), from which signals the directional signals VL and VR may be regenerated. As described, the signals A and B are broadcast and the directional signals VL and VR are regenerated at a receiver to effect stereophonic reproduction. Apparatus for deriving two compatible signals.-The left and right signals VL and VR, which may be derived from crossed directional microphones, appear in channels 1 and 2, respectively (Fig. 1). ). VL is applied to two summing circuits 3 and 4, directly in the case of 4 but through an amplifier of gain two in the case of 3, while VR is applied directly to 3 and 4. The output of 3 is therefore 2VL + VR and that of 4 is VL + VR. These two signals, which constitute the signals A and B, amplitude modulate a carrier wave from oscillator 8 in modulators 6 and 7, the filters 9 and 10 suppressing the lower and upper sidebands respectively, and the remaining sidebands being mixed at 11. Stereophonic reproduction from signals A and B.-The received signals are applied to filters 14 and 15 (Fig. 2), corresponding to 9 and 10 (Fig. 1), which select the upper and lower sidebands respectively and apply them to demodulators 16 and 17 to derive signals A and B. Signals A and B are applied to the differencing circuit 18 which produces A-B, namely VL Signal B is also applied via an amplifier 19 of gain two to the differencing circuit 20 where A is subtracted to produce 2B-A, namely VR. The signals VL and VR are amplified at 21, 22 and fed to spaced loud-speakers 24, 25. Modified arrangements.-In the arrangement of Fig. 3 (not shown) the signals VL and VR are applied to a circuit which produces a relative phase shift of 90 degrees between them to produce VL and jVR. These signals are added to produce A and subtracted to produce B. At the receiver (Fig. 4, not shown) the signals A and B derived by filtering and demodulating the sidebands are summed to produce 2VL and differenced to produce 2jVR, these signals then being passed through a circuit which produces a relative phase shift of 90 degrees between them to derive signals representative of VL and VR which are fed to the loud-speakers.

Title: Improvements in and relating to timing devices, more particularly for electric motor starting and controlling mechanism
IPC: H01H50/88
Filed: 1933-11-22
Abstract: 417,086. Actuating and retarding controllers. BRITISH THOMSONHOUSTON CO., Ltd., Crown House, Aldwych, London. Nov. 22, 1933, Nos. 32628 and 32629. Convention dates, Nov. 23, 1932. [Class 38 (iii).] A timing device, particularly for delaying the closure of electric contacts (13-15) in a motor starter, comprises an anchor 48 coacting with a scape wheel 45, an oscillating mass 49, whose pivotal axis is parallel to that of the anchor, and a driving connection (bolt 56) between an arm 50 on the anchor and the mass (slot 55) which connection is adjustable radially in the arm 50 and slot 55 to vary the periodicity of the mass 49. When the solenoid 18 of the motor starter 10 is energized, plunger 20 rises and rocks a member 23 clockwise, Fig. 5, to close contacts 11, 12. An initially stressed spring 28 connects member 23 to a shaft 26 and its action is retarded by the timedelay device 45, 48, 56, 49 which is marked generally at 19, 41, 40 in Fig. 1. The end 25 of shaft 26 carries the contact arms of accelerating contacts 13-15, which latter close in time sequence. Subsequently, a part 34<a> connected to the outer end of spring 28 and to shaft 26, opens the contacts 11 to reduce the energization of the motor field winding.

Title: Improvements in resilient joints
IPC: F16D3/76
Filed: 1935-11-25
Abstract: 445,255. flexibleunjointed hinges. HOUDAILLE, M., 50, Rue Raspail, and LECLER, C., 3, Rue Trezel, both in Levallois- Perret, Seine, France. Nov. 25, 1935, No. 32658. Convention date, Dec. 26, 1934. [Class 65 (ii)] A resilient joint comprises a rubber strip 3 wound in a spiral between two co - axial sleeves 1, 2, the rubber being slightly compressed, and bonded if necessary, with inextensible threads 5 glued to the rubber strip transversely to the length thereof, to prevent extension of the rubber in the direction of the axis of the joint. The threads are preferably of textile material, so as not to resist distortion of the rubber other than extension transverse to the strip, and they may be connected together initially by fragile threads running longitudinally of the strip, forming a large mesh fabric which is gummed to the surface of the rubber strip, the longitudinal threads being broken by the slightest longitudinal elongation of the rubber strip to leave only the transverse threads effective. This construction of joint provides considerable resilience under radial load without the danger of breaking the bonding at the upper side of the joint, since the rubber compressed at the lower side, being prevented from flowing endways, flows up at the sides of the joint to fill the increased space at the top.
Patent GB-655537-A (GB)
Title: Press for compressing and extruding granular material
IPC: B29C43/00
Filed: 1948-12-17
Abstract: 655,537. Extruding carbon electrodes &c. LOEWY ENGINEERING CO., Ltd. (Loraut, H.). Dec. 17, 1948, No. 32662. [Class 87 (ii)] Granular material, e.g. carbon and a binder, is fed from a hopper 15 through a conduit 16 mounted on a movable cross-head 4 into the axial bore 13 of a piston 5. The material is pushed towards a plate 12 by a reciprocating plunger 36. Several strokes of the plunger 36 are made to push several charges of material towards the plate 12 and to fill a container 8 with the material. The piston 5 is gradually moved back out of the container by the pressure of the material acting against a predetermined hydraulic pressure in cylinders mounted in a fixed cross-head 1. When the amount of material necessary to fill the container equals the amount of material in the bore, the plunger 36 is moved forwardly until a shoulder 45, Fig. 4, engages the cross-head 4. The plate 12 is raised and the piston 5 and the plunger 36 are moved forwardly to extrude the evenly-com. pacted mass of material 47 through a die 10. The cross-head 4 moves with the plunger 5. Alternatively, both the container and the bore may be filled, and then the plunger 36 need not be moved forwardly until the shoulder 45 engages the cross-head 4. The plunger 36 is so controlled that its forward strokes are of the same length regardless of the position of the cross-head 4. Passages 29, 30, 31 and 32 are provided for heating or cooling fluid.

Title: Improvements in or relating to a flutter damper
IPC: B64C13/00
Filed: 1952-12-24
Abstract: 743,788. Rotary hydraulic dampers. HOUDAILLE-HERSHEY CORPORATION. Dec. 24, 1952 [Feb. 9, 1952], No. 32745/52. Class 108 (3). A damper for preventing flutter of aircraft ailerons, flaps, &c. comprises a rotary piston 15 co-operating with pressure reacting members 44 rigid with a housing 14 to define at least a pair of working chambers 39, 40, ports 72, 79 leading from the chambers to accommodate fluid displacement between the chambers 39, 40 on relative movement between the piston 15 and the housing 14, and a movable device A providing fluid inertia, connecting together the fluid displacement ports 72, 79. As shown, there are two chambers 39 and two chambers 40. The working chambers 40, 40 are connected by ports 72 with a chamber 65 in the shaft 15. Members 74, 76 in the chamber 65 form the housing of a fluid motor A having a rotor 96 carried by a shaft 97. Sliding vanes 99 carried by the rotor 96 engage a spreader ring 100 at their inner ends. The outer ends of the vanes engage the inner periphery of a ring 101, the outer periphery of which is toothed and is eccentrically disposed relative to its inner periphery. The performance of the motor A is varied by rotation of the ring 101 by means of an adjustment rod 105 having an indicating pointer 106. The motor A is disposed between a passage 110 leading to the chamber 65 and a passage 109 leading to the hollow bore of a plug 77. The arrangement is such that flow from the passage 110 to the passage 109 or vice versa, through the motor, will result in movement of the rotor in one or other direction of rotation respectively. The plug 77 is formed with a chordal slit-shaped orifice 85 which intersects its bore, and connects the latter with a chordal slit-shaped orifice 83 in a member 82. An annular channel 81 connects the orifice 83 with ports 79 which lead to the chambers 39, 39. The plug 77 may be rotated by means of an adjustment rod 86 having an indicating pointer 90 to vary the restriction offered by the co-operating orifices 83 and 85. Between the rod 86 and the plug 77 is a thermostatic element 89 which compensates for the effect of temperature change on viscosity. The system is maintained charged with liquid by the action of a spring- loaded piston 21 in a chamber 20, which is connected by passages 38 with the working chambers. The chamber 20 is replenished by a valve (Fig. 3, not shown), which is tangentially-disposed to the periphery of the chamber, and includes a spring-loaded valve element and a resilient sealing member secured by a threaded plug. The radial wall members 44 are secured at the ends by pins 61, and to the barrel by screws 63. In operation, the fluid motor A produces an inertia effect similar to that of a long fluid passageway, and together with the orifices 83, 85 develops a resonant frequency within a selected frequency range. The arrangement compensates for the elasticity of the device and the working liquid. Specifications 712,321 and 719,827 are referred to.

Filed: 1953-11-26
Abstract: 753,528. Floors. SEMTEX, Ltd. Oct. 11, 1954 [Nov. 26, 1953.], No. 32796/53. Class 20(4) In the production of jointless floors a concrete supporting floor is provided with a coating of resinous or quasi-resinous material by first applying to the supporting floor a priming layer containing an aqueous rubber dispersion and afterwards applying, while the priming layer is still wet, a top layer containing a hydraulic cement and an aqueous emulsion of resinous or quasi-resinous material. Preferably the priming layer also contains a hydraulic element and possibly a proportion of filling material such as sand or crushed stone. The rubber dispersion may contain curing agents, accelerators, anti-oxidants or a stabilizer and preferably contains 35-60 per cent by weight of solids. The hydraulic cement may be Portland or aluminous cement or a mixture of the two. Suitable aqueous emulsions of resinous or quasi-resinous materials are those based on asphalt or bitumen, a natural or synthetic resin, e. g. polyvinyl chloride, polystyrene, coumaroneindene and coumarone-styrene resins, a natural or synthetic rubber, a solid grade of aromatic petroleum residue, a blend of polyvinyl acetate with pitch, a residual pitch of the kind obtainable from the distillation of animal and vegetable oils and fats, or a blend of such a pitch with a vinyl resin or with a rubber or other elastomeric material. The proportion of hydraulic cement in the top layer is varied as necessary and mineral aggregates, filler and numeral pigments can be incorporated therein as desired. In an example a priming mixture containing 20 lbs Portland cement and 25 lbs fine washed sand mixed with 7 lbs. stabilized rubber latex and 2 1bs. water was prepared. This mixture was brushed firmly over the surface of the concrete at a rate of about ¥ lb. of mixture per square yard of concrete. The compound to be applied as top layer had a composition: bitumen emulsion 16 lb. ; Portland cement 14 lb. ; iron oxide pigment 1À5 lb. ; granite chippings 48 lb. ; sharp sand 24 1b. This composition was applied about ten minutes after the priming layer had been applied.
