Title: Improvements in or relating to Electrical Signal Modifying Circuits
IPC: H03K3/353
Filed: 1968-06-11
Abstract: 1,156,270. Charging capacitors. HONEYWELL Inc. 11 June, 1968 [12 June, 1967], No. 27603/68. Heading H2H. [Also in Division H3] An electrical signal modifying circuit comprises capacitance which is arranged to become gradually charged following the applications of of an alternating input signal to the circuit, and to produce a gradual change in an output signal from the circuit, the gradual change being consequent upon the gradual charging of the capacitance, comprising switching means which is operable to repeatedly switch the capacitance into and out of a current path in the circuit. In one embodiment a square wave from terminal 12, Fig. 1, is applied to output terminal 18 via series resistance 16. Terminal 18 can be connected to the common earth terminal 14, either via the emitter to collector path of field-effect transistor 22 or via capacitor 26 and the emitter to collector path of field-effect transistor 24. The bases of the transistors 22, 24 are driven respectively in phase and out of phase with the signal: it is shown in the specfication that this results in a suddenly applied signal producing an output signal which commences at zero and rises at a rate the time. constant of which is 4RC, where R is the value of resistance 16 and C the value of capacitance 26. In a second embodiment a square wave from terminal 12, Fig. 2a, is transferred to output terminal 18, which is connected to the common earth terminal 14 by way of resistor 16, via capacitor 20 and either the emitter to collector path of transistor 22 or capacitor 26 and the emitter collector path of transistor 24. The bases of the transistors 22, 24 are driven respectively in phase and out of phase with the signal: it is shown in the specification that this results in the output at terminal 18, on the sudden application of a signal to terminal 14, commencing at full amplitude and diminishing exponentially with a time-constant given by 4RC where R is the value of resistance 14 and C the value of capacitance 26. In an alternative arrangement (Fig. 2b, not shown) a switch is used, operating in synchronism with the input signal, to switch a capacitor in and out of the series signal path.

Title: Improvements in thermostatic devices
IPC: G01K9/00
Filed: 1930-09-16
Abstract: 361,475. Valves actuated by tipping tanks. LAMBERT, F. T., 49, Park Road, East Hill, Wandsworth, London. Sept. 16, 1930, No. 27647. [Class 135.] A device for controlling electric or gas-heated cookers or like apparatus, includes a weighted lever or balance in which liquid flows out of a reservoir on one side of the balance until the latter tilts to operate a switch or gas-cock connected thereto, the rate of liquid flow being regulated by a thermostatic - device actuated by the heating applied to the apparatus. In one form, a piston valve g for controlling the rate of flow of the liquid is situated in an axial bore in a pivotally mounted cylinder b and is actuated by a bimetallic expansion device h. Portions b<1>, b<2> of the cylinder b carry reservoirs c, c<1> respectively, which are connected through a byepass l and two ports f, f<1> situated on either side of a semicircular or other groove in the valve g. A U-shaped member j mounted on the reservoir c normally connects two electrical contacts k, k<1>, the electric circuit, being. broken when the apparatus tilts. The period of time before the reservoirs tilt can be further controlled by an adjustable jockey weight m<1> and the tilting of the apparatus is limited by a pin d engaging the end of a groove in the cylinder b. The apparatus is reset by being turned into a vertical position and allowing the oil to run back through the byepass An air vessel with a movable piston or diaphragm may replace the bimetallic device and a needle valve may replace the piston valve.,

Filed: 1976-07-05
Abstract: 1495922 Driving spinning rings SPURMACH ESPANA SL 5 July 1976 [4 June 1976] 27893/76 Heading DID A ring spinning system with driven rings is arranged so that rotation of the rings is stopped prior to stoppage of the remainder of the machine as determined by the controller of the final stroke before the end of 'that stroke, and when the machine is started the ring rotation is started after the start of the machine as determined by an adjustable time delay. Drive is taken to the rings from a drive belt 3 via pulleys 6 with cylindrical extensions 7 about which belts 11 run to carry drive to the ring rails 13. The first two rings 14 of the ring rail are driven by a belt about their upper periphery. The ring mountings then drive a tangential belt 15 within the ring rail which transmits drive to the remaining rings. The belt 11 which takes drive into the ring rail has a tensioning roller 12 which allows for the slight movement of the ring rail while the rings are not rotating at the beginning and end of spinning. The main drive belt 3 has rollers 9 which support its lower edge.

Abstract: 854,767. Cleaning metals. OSBORN MANUFACTURING CO. Sept. 6, 1957 [June 18, 1957], Nc. 28250/57. Class 82(2) A mechanism for sharply flexing travelling elongated d metal articles comprises a pair of large diameter work rolls arranged to flex the article over a smaller diameter, indirectly driven work roll without reducing the thickness of the article, the smaller roll being located between the two larger rolls with its surface lying wholly between the two common parallel tangents to the larger rolls. As shown, a metal strip S is led under a large roll 25 and over a small roll 21 situated between the roll 25 and a second roll 24 under which the strip passes. The small roll 21 is supported by an intermediate back-up roll 20 and a large power driven back-up roll 7, the roll 21 being driven frictionally by the back-up rolls. Rotary brushes 38, 39 clean the surfaces of the large back-up roll 7 and the large work rolls 24, 25 respectively, a shoe 40 being inserted between rolls 24, 25 to prevent any pieces of scale or dirt removed by the brushes from falling on to the strip. The rolls 7, 20 and 21 may be moved downwardly and the rolls 24, 25 as a group may be moved upwardly to allow access to the small roll 21 The large roll 25 which first makes contact with the strip may be of slightly smaller diameter than the roll 24. The small diameter roll 21 may be mounted in a floating bearing by resiliently deformable members. Two mechanisms may be used in series with the smaller work roll in the second located on the opposite side of the strip from that of the first. Other modifications of the arrangement of back-up rolls are described, the intermediate and small roll off-set.

Abstract: 1,100,811. Winding stators. FORT WAYNE TOOL & DIE Inc. 6 July, 1965, No. 28561/65. Heading B3A. In a stator winding machine for winding at least two concentric coils and provided with a reciprocating and oscillating gun 22 having wire dispensing needles 24 corresponding to the number of pole groups to be wound, shroud members 30 are secured to the stator core members 26 by a pin-ring 45 and roll-out finger assemblies 32, 34 are provided to hold the end turns of the coils outwardly away from the bore of the core members. The assembly 32 comprises a nest plate 36 removably supported on a platen 38 and a group of roll-out fingers 40 pivotally mounted on the plate 36. The assembly 34 comprises a clamp-ring 44 with fingers 46 pivotally mounted therein and the assembly is reciprocable. As the assembly 34 is lowered, the inner fingers 124, 124a are depending to clear the shrouds 30 and they are cammed into an upstanding position against spring loaded detents 156 by the pin ring 45. The outer fingers (126) (126a) are spring loaded into an upstanding position Fig. 6 (not shown). As the coils are wound, the enlarged bulbs on the shrouds 30 guide the wire into the fingers, thereby preventing the wire extending chordwise across the stator, (Fig. 9, not shown), When winding is completed, the end turns 170 of the coils are located in the hooks of the fingers and as the assembly 34 is withdrawn, the coils act as cams on the fingers and cam them through approximately 90 degrees. The inner fingers 124 are retained by the detents to clear the bulb and the outer fingers (126) are returned by their springs when clear of the coils. The stator 26 is removed manually from the assembly 34, the fingers 124a, (126a) acting as in the assembly 32. As the next stator is positioned for winding, the end fase 78 of the core 26 re-sets the inner fingers against the action of their detents.
