Title: Improvements in butterfly valves
Inventor: MASHEDER HENRY ALBERT
IPC: F16K1/226
Filed: 1957-01-16
Abstract: 824,569. Valves. GORDON & CO. Ltd., J. Jan. 15, 1958 [Jan. 16, 1957; March 12, 1957; Aug. 20, 1957], Nos. 1708/57, 8165/57 and 26322/57. Class 135. A butterfly valve in which the wings of the valve are carried on a spindle has the spindle braced between its ends by at least one bearing carried on a member fixed within the valve body in a manner permitting the valve to open. At intervals across its diameter the valve plate 6 is formed with cutaway portions exposing arcuate sections 8 of the valve spindle 5. Bearing pads 9 supporting the spindle through the cut-away positions 8 are mounted on webbed members 10 fixed at 11 to the valve casing. A bridge piece in the form of a narrow web 12 parallel to the spindle 5 interconnects the webs 10 and is itself fixed to the valve casing 1. In another embodiment a horizontal bridge member is welded with the casing and carries a number of bearings in the form of complete rings. These rings intermesh with similar bearing rings integral with the valve plate and the valve spindle is passed through the rings in the manner of a pin in a butt hinge. The spindle may be supported at its ends in bearings in the wall of the valve casing or may be shorter in length than the diameter of the valve casing and be supported entirely by the bridge member. When a spindle shorter than the internal diameter of the casing is used a spindle carrying a cranked arm connected by a link to the valve plate may be used to actuate the valve. Alternatively, a rack and pinion may be employed. Where complete rings are employed as bearings for the spindle the supporting bridge may be located either upstream or downstream of the valve.

Patent GB-1516961-A (GB)
Title: Guide device for a drawer
IPC: A47B88/493
Filed: 1977-01-17
Abstract: This device has a U-shaped guide rail (1), to be fastened in the item of furniture, and a roller cage (3) which can be moved along in said rail. A receiving rail (4), to be fastened on the drawer, is guided between the rollers (2) of the cage (3). The roller cage (3) is produced in one piece from a visco-elastic polymer by injection moulding. Between two rigid legs (31, 32) there are provided two spaced-apart, flexible tongues (33, 34) which are formed by a reduction in cross-section and of which one (34) is corrugated and acts as a resilient tension member on the rigid cage legs (31, 32). The cage is fitted with projecting pins (35), while the receiving rails (4) have recesses (41) for the engagement of the pins (35). In the depicted end position, the roller cage (3) is thus automatically locked to the receiving rail (4), before the drawer with receiving rail (4) is pulled out, if the roller (2) runs beyond the front edge (12) of the upper leg of the guide rail (1). When the receiving rail is inserted, the roller cage (3) is automatically released again. <IMAGE>

Title: Television transmitting system
IPC: H04N9/07
Filed: 1942-02-11
Abstract: 555,213. Cathode-ray tubes. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 11, 1942, No. 1827. Convention date, Feb. 11, 1941. [Classes 39 (i) and 40 (iii)] In colour television transmission tubes the mosaic is flooded after each scan with low velocity electrons from a source independent of the electron gun used for scanning, the flooding taking place during a portion only of the fly back period of the beam. Signals are not generated during the fly back period. Pictures are projected on the mosaic 20 through colour screens 48, which may consist (i) of a disc divided into sections R, G, B, Fig. 2a, or (ii) of segments R, G, B, Fig. 2b, separated by opaque parts 54 ; with the second form the mosaic is scanned in darkness. To flood the mosaic one or a number of separate cathodes 56 are used, each with a control electrode 60, whose potential is sufficiently negative to prevent electron flow from the associated cathode. The impulse generator 36 controls the vertical deflection of the scanning ray and has means associated therewith for giving during a portion only of the fly back period a positive impulse to the control electrodes 60 whereby electron flow is allowed ; also associated with this generator and with the generator 32 for the horizontal deflection are means to apply negative impulses to the control electrode 14 of the gun to prevent electron flow during the whole of the fly back periods from the main cathode 12. In a modification the control electrodes 60 are dispensed with, the cathodes being held normally at a potential positive to the accelerator electrode 18 ; for the flooding period a short negative potential period of the cathode is obtained. The flooding means may be used with arrangements using different lenses for each colour or with moving picture films, where successive frame images are of different colour. Specification 434,942 is referred to. The Specification as open to inspection under Sect. 91 also states that the flooding means may be used in other forms of television transmitting tubes and also where a residual charge on the mosaic is eliminated only after two or more scanning cycles. This subject-matter does not appear in the Specification as accepted.

Title: Inverter circuit
IPC: H02M7/523
Filed: 1976-01-21
Abstract: 1532273 Inverting RCA CORPORATION 21 Jan 1976 [5 Feb 1975] 02308/76 Heading H2F In an inverter of the type comprising a pair of switching devices 24, 28 connected in series across supply terminals 10, 12 and having a load, such as an induction heating coil 14 connected between the junction of switching devices 24, 28 and that of a pair of capacitors 16, 18, the central circuit is responsive to the load current and is arranged to delay turn-on of either device 24, 28 until after the turn-off time of the other device. Provision is also preferably made for interrupting operation if the load current is excessive. As described, the load coil 14 is a flat spiral of an induction cooker. When thyristor 24 is turned on, capacitor 18 is charged resonantly via coil 14 un. til the current reverses and is taken over by diode 22, turning off 24, at the end of the turnoff time, thyristor 28 is turned on, so that 18 discharges and 16 charges, both via coil 14. A sine wave at 18 kHz thus flows in coil 14. Control circuit (Fig. 2).-The voltage at the secondary of transformer 20 is squared and differentiated at 40-46 and the resulting pulses (corresponding to each passage through zero of the load current) trigger a monostable 50 which increases the duration, at least to the turn-off time of the thyristors. After immersion at 154, a bistable 54 provides complementary square vanes for triggering the thyristors 24, 28 Simultaneous conduction of the thyristors is thus prevented.  Over-current protection and time ratio control.- The heat produced by the induction coil 14 is variable by control of the duty cycle of pulses from control 66 which determines the number of ultrasonic cycles in each burst. A low frequency astable multivibrator (Fig. 5, not shown) feeding a sawtooth generator having a manually controllable slope. The sawtooth is converted into a low frequency variable duty cycle wave for controlling a bistable 64 which inhibits triggering of the inverter in one of its states. A rectifier 60 is responsive to load current and, if successive (e.g. due to removal of the pan from the coil 14, breaks down zener diode 104 and resets bistable 64 so as to inhibit the inverter or to reduce its duty cycle. The heating output may also be increased by closing switch S1.

In the latter case the operation may be performed in another mill, or in the same mill by setting the rolls 19, 20 closer together. Preferably the strip 15 is crushed in alternate spaces only. This may be effected by making alternate ribs 21 of the roll 20 with projecting rounded peripheries 22. Preferably the edges of the ribbons are grooved to receive the crushed metal. The ribbons are finally secured by welding or brazing, preferably by copper brazing in presence of hydrogen.
