Abstract: 1,162,169. Rollers. SAMUEL BINGHAM CO. 22 Nov., 1967 [7 Dec., 1966], No. 53272/67. Heading F2U. A steel mill roller, for use in sheet pickling solutions, tin plating &c., comprises a metal core 12, a layer of hard reinforced plastics, and a rubber or synthetic rubber cover 16. As shown, a protective layer of reinforced plastics 13, hard, rigid, mineral acid resistant and cut or crack growth non-propagating and of “ to # inch thickness, is formed on the metal core by winding thereon fibrous glass rovings, woven tapes or fabrics, or other fibrous materials such as nylon, asbestos or mineral wool, soaked in acid-resistant polyester or phenolic resin, or melamine, or a resin based on Bisphenol A, the layer then being surface ground with a 0À002 inch/inch longitudinal taper. The layer 13 covers any acid throw rings forming part of the core and leaves only the roller journals clear. The cover 16 is preformed by winding, to a 1/16 to # inch thickness, the same reinforced plastics as the layer 13 on a mandrel having the same taper as said layer to provide a lining 18, applying to said lining a thin coat of cement, building on calendered rubber or synthetic rubber to provide a sleeve 19 of ¢ to 1 inch thickness, winding webbing around the covered mandrel, vulcanizing, surface grinding, end trimming, and removing the cover from the mandrel. To mount the cover on the core, the latter is suspended above the cover vertically positioned, both larger diameter ends uppermost, a reservoir-forming collar (21) is temporarily mounted on the cover upper end, and, as the core is slowly lowered into the cover, a quantity of the same resin as used to make the layer 13 and the lining 18 is continuously poured into the mouth of the collar. After trimming-off in a lathe a light coating of waxcontaining resin is applied to all exposed portions of the reinforced resin. To re-cover a roller thus formed, it is necessary merely to strip the damaged cover 16, re-grind the thus exposed surface of the layer 13, and apply a new cover 16. For light use, the layer 13 may be dispensed with and the lined cover 16 held on the cover by end clamps.

Filed: 1976-12-22
Abstract: 1536040 Automatic fine tuning SONY CORP 22 Dec 1976 [26 Dec 1975 (2)] 53562/76 Heading H3A  In an automatic fine tuning circuit of a TV receiver having a comparator 21 which compares the average voltage level of the output of the video detector 6 with a reference to provide a first detecting signal P 1  and a frequency discriminator 17 connected to the video I.F. amplifier to provide a second detecting signal P 2 , a circuit 18 is responsive to the output of the video I.F. amplifier to select the second signal P 2  for control of the tuner 1 when the frequency to which the tuner is tuned is within a predetermined frequency band that includes a TV channel signal and to select the first signal P 1  for control of the tuner when the tuner is tuned to a frequency outside the frequency band. The average level is detected at 19 and a peak detector 20 provides the reference to the comparator 21. A sum signal determined by an envelope detector 23, amplifier 24 and detector 25 controls switching circuit 18 to connect the discriminator output P 2  so as to control the oscillator 4 when the tuner is tuned to a frequency close to the desired frequency such as f 0   50 kHz to f 0   1 mHz. When the tuner is tuned to a frequency f 0   1 mHz to  4 mHz the switching circuit 18 connects the signal P 1  to control the A.F.T. voltage V f  so as to bring the tuning within the range of the control provided by the discriminator. If the tuner is tuned to a frequency beyond f 0   4 mHz noise detected at 27 provides a signal P 4  to disconnect at 26 the fine tuning signal from the tuner. The receiver shown has a mechanical channel selector. In an alternative (Fig. 5, not shown) tuning is obtained by an up/down counter 35 the count of which is determined by up/down switches (37U, 37D) or selectively by a memory 32 so as to provide via a D/A converter 31, 51, 52 a tuning voltage to an electronic tuner 1. Automatic fine tuning by a transistor circuit (50) disclosed in detail (Fig. 8, not shown) controls via (EU, ED) the fine up/ down count of the counter. Circuit (50) has transistors (64 and 65) which function as the switch 18 and a transistor (81) which conducts in response to the presence of the noise signal P 4  to provide the function of circuit 26. Specifications 1,518,712 and 1,526,880 are referred to.

[Also in Divisions H2 and H3] In a supervisory circuit for traffic light signalling for preventing two green signal lamps from operating simultaneously two green signal lamps V 1 , V 2  are connected across a supply via separate switching devices S 1 , S 2 , two diodes D 1  and D 2  are connected in series opposition between the lamps and a relay R is connected between the supply and the interconnection of the diodes. With both lamps V 1 , V 2  OFF current flows via the diodes D 1 , D 2  to the relay R which maintains the supply I, II connected. When switch S 1  or S 2 , which may be thyristors, are closed to light either lamp V 1  or V 2  one of the diodes D 1  or D 2  cuts OFF. However, current is maintained to the relay winding R, via the other diode D 2  or D 1 , so as to maintain the supply to the lamp which is on. If both switches were closed together the relay R is de-energized and disconnects the supply from the lamps and switches on yellow or orange flashing lights. If one of the green signal lamps or fuses connected in series with these lamps becomes defective then the relay R is also de-energized or an alarm will also be operative when the other green signal lamp is switched in. Also the circuit responds to an interruption of the supply to the relay. The supply I, II may be A.C. or D.C.

Abstract: 1,176,199. Wave-energy position finding. R. D. EVANS. 4 Dec., 1967, No. 55106/67. Heading H4D. In an aircraft guidance system three waveenergy detectors are located at different positions on the aircraft, the outputs of the detectors are paired to produce two intensity ratio measurements, and the measurements are utilized to determine the range and bearing of the aircraft from the source of the waves. The waves may be radio waves, compressional waves, invisible or visible light, gamma rays etc.; a laser may be employed. The " source " may be self-emitting or a transponder. In an embodiment, detectors Ia, Ib, Ir on an aircraft are connected to ratio circuits 3, 5, the outputs from which are fed to an X-Y plotter 2 to afford range and bearing information. By applying the output of a subtracting circuit 11 to the ordinate of the plotter and the output of a summing circuit 13, a convenient measure of range and bearing is obtained. A conventional computer may be added to give range and bearing indications on respective meters 15, 17. Elevation angle data is derived utilizing a fourth detector 14 spaced below the plane defined by detectors Ia, Ib, Ic. Differentiation may be added to give rate information. The law of wave attenuation may not be known: it may be computed from a quoted equation when detectors Ia, Ib, Ic are made almost collinear or correction for attenuation may be made by utilizing a further detector. Extraneous background or noise effects can be removed utilizing a further detector. In the above the detectors are fixed on the aircraft, they may be movable as illustrated to afford a check on position data measurement or for correcting the effect of extraneous waves. Source strength may also be measured.
