Filed: 1950-07-14
Abstract: 677,380. Endless conveyers. EICKHOFF, MASCHINENFABRIK UND EISENGIESSEREI, GEB. July 14, 1950. [Aug. 4, 1949] No. 17631/50. Class 78 (i). The driving rotor of an endless band or chain conveyer is driven by a rotary engine through reversible fluid power drive mechanism provided with regulating means for continuously varying the speed of the rotor. As shown, the electric motor 2 drives a pump 8 which supplies fluid to two motors 9, 12 which drive respectively the drums 1, 7. The end drum 1 of the band is driven by the more powerful motor 9, the band running from this drum to the second drum 7. The fluid supply from pump 8 is regulated by a wheel valve. In an alternative form, not shown a single drum is driven from a single fluid motor which is housed in the same casing as pump driven by the motor 2. This drive, at one end of a conveyer band, may be supplemented by a second electric motor driving a drum at the other end of the band through positive gearing, and disengageable from this drum.

Abstract: 1465103 Automatic current control UNION CARBIDE CORP 23 April 1974 [24 April 1973] 17631/74 Heading G3R A power supply arrangement for regulating the current in an electric arc includes a magnetic control element with a D.C. control winding. The D.C. control current is supplied through a gated rectifier bridge in accordance with a comparison of a feedback signal, a sawtooth signal, a D.C. reference voltage and a control pulse signal. As shown, a magnetic amplifier or saturable reactor 12 has a main winding connected in series with a power source 10 and an arc working electrode E. The arc current is determined by the current in control winding 14 which is connected in series with a current measuring resistor RF across an SCR bridge 18 supplied from an A.C. source 16. The SCR's are gated during each half cycle at the instant when the output of a differential amplifier 28 changes from negative to positive polarity. The amplifier 28 receives a filtered feedback signal from resistor RF, and a sawtooth signal synchronized with the source 16 from a conventional ramp generator 22. A D.C. reference level is provided by a source 24, and the level of the arc working current is switched between low and high levels by a pulse circuit 26 including PUT switching circuits and NAND logic; Fig. 3 (not shown), at a variable frequency between 1 and 20 c.p.s. which is asynchronous with the source 16.

Title: Improvements in or relating to methods of, and apparatus for, forming accurately shaped outer surfaces on glass tubes
IPC: C03B23/07
Filed: 1953-06-26
Abstract: 734,461. Glass manufacture. GENERAL ELECTRIC CO., Ltd., DAVIDSON, T. R. N., and SCRUTON, A. H. June 25, 1954 [June 26, 1953], No. 17824/53. Class 56. A part of the external surface of a glass tube is accurately shaped and dimensioned, as a surface of revolution, by rotating the tube about its axis, softening the glass over the part to be shaped, creating an excess pressure within the tube so as to force the softened glass outwardly into contact with a roller or rollers which impart the final shape to the glass. As shown in plan in Fig. 1, the glass tube 3 is closed by end bungs 1, 2, the latter having a connection 4 with an air pump. The tube is held in two opposed rotary chucks (not shown), one of which is displaceable along the axis of rotation for insertion and removal of the tubes. The glass is softened by a gas burner 5 with jets 6, and cylindrical iron rollers 7 are accurately positioned, by a right- and lefthanded screw adjustment 14, 15 on each side of the tube. The screw 14, 15 is mounted in a central stationary bearing on the base 11 and the blocks 10, which carry the rollers, slide on the base on which stops are adjustably secured to limit the inward movement of the rollers. The chilling effect of the rollers reduces the temperature of the glass to below its softening point, the gas flames then being lowered to reduce the strains in the glass. The air pressure is then released. A conical part of a glass tube may be accurately shaped by using cylindrical rollers with their axes inclined to the axis of rotation, or by using frusto-conical rollers. The neck portion of a cathode-ray tube may be accurately formed, either before or after it is secured to the bulb portion of the envelope.

Abstract: 750,879. Roller conveyers. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. June 18, 1954, No. 17897/54. Class 78 (1). One of the bearing pivots 4 of a roller 2 is provided with a cylindrical boring 5 which is heated to permit the insertion of an extension 6 of the shaft of the driving motor 1. When the bearing cools, the shaft is held firmly. A duct 7 closed by a threaded plug 8 connects the boring 5 to the outside of the bearing. During heating by a torch flame the plug is removed to allow the combustion gases to escape. When the parts 4, 6 are to be disconnected, the shaft 6 is forced out of the boring by high pressure oil supplied to the duct 7 through a pipe-line. A stop member 9 fixed to the motor 1 is inserted in a yieldable intermediate member 10 mounted in a sleeve 11 fixed to the bearing pedestal 3.

Title: Improvements in and relating to photographic contact printing apparatus
IPC: G03B27/20
Filed: 1925-06-16
Abstract: 258,212. Sack, W. June 16, 1925. Elastic valves; closure members. - In photographic apparatus in which air is exhausted from between a glass plate and a rubber cover enclosing a negative or sensitized sheet between them, automatic valve means is provided for cutting off the suction and admitting air between the plate and cover when the frames are separated. The rubber sheet, Fig. 1, is in a frame 5 which has a limited vertical movement relatively to the frame 4, and is supported centrally by a board supported by springs on the frame 4. The glass plate 16 with an aperture 23 is mounted on a frame 15 which can be moved to and from the frame 4 by screwed spindles 8. The suction pipe 25 passes through the trunnion 14 of the frame 15, and communicates with the opening 23 in the glass plate 16 through a valve comprising a bell shaped piece of rubber 27, Fig. 6, having an inner bell shaped valve port 29 and mounted centrally over the opening 23. The valve is encased in a metal cover 32 over which is a metal dome 36 pressed down by a screw 35<1> in a bracket 35" on the frame 15. A central squared rod 35 has a head 30 within the valve, passes through an aperture 28 thereof, and is attached to an arm 42 on a rod 41 sliding through the frame 15 and adapted when the frames are closed for printing to engage the bracket 3. When this happens the rod 35 is raised, thereby raising the head 30 and the inner valve part 29 away from the glass, sealing the valve from admission of air through the openings 33 and the aperture 28, and putting the suction pipe 25 into communication with the opening 23. When the frames 15 and 4 are separated the rubber sheet and frame 5 are first raised with the glass, but the rod 35 and the head 30 fall, allowing the part 29 to return to normal position against the glass, thereby cutting off the suction from the opening 23. Also air enters through the openings 33, the aperture 20 and channels 40 in the head 30, to the opening 23. thereby releasing the rubber sheet and frame 5. The valve part 29 may have an inturned lip 39 on which the head 30 normally presses.

Abstract: 497,605. Television. FARNSWORTH TELEVISION, Inc. June 30, 1937, No. 18150. Convention date, July 11, 1936. [Class 40 (iii)] Line synchronizing signals are interrupted by the frame synchronizing signals, as in Fig. 2, and are transmitted on a carrier separate from that transmitting the picture signals but of the same frequency. The train of synchronizing signals is preferably produced by applying the line synchronizing signals positively to a valve biassed to cut-off while the frame synchronizing signals are applied negatively. According to the Specification as open to inspection under Sect. 91, the carriers may be of different frequency. A circuit for separating the line and frame synchronizing signals is shown in Fig. 5 (Cancelled), the line impulses being taken from 41 and the frame impulses from 44, the line impulses being integrated by condenser 39, so that an interruption is effective at 44. This subjectmatter does not appear in the Specification as accepted.
