Abstract: 281,961. Briggs, G. E. June 21, 1927. Bookbinding.-Relates to apparatus for use in conjunction with a wire-stapling machine for binding folded sheets or sections into book form upon a number of tapes disposed transversely to the backs thereof. The tapes p, Figs. 1 and 2, are stretched between the two tubular limbs t of a rectangular frame e which is slidable upon a pair of parallel rods b supported by end spreaders c, the ends of the tubular members t being connected by transverse braces f, l. The spreaders c are secured by clamping-bolts to end brackets m provided with slots to enable the level of the tapes to be adjusted to the height of the saddle of a stapling-machine which is disposed between the rods b. The saddle is arranged in the longitudinal direction of the machine so that when a. book section is placed over it and the frame e moved along to align one of the tapes in its correct position at either the top or bottom of the back edge of the section, the staples can be applied transversely across the tapes and enter the folds of the sheets without perforating the tapes. After the application of the first staple the frame is moved along on the bars b for the application of the next staple, which may be secured at the. other end of the back of the book section or in an intermediate position. Adjustable stops g secured by thumbscrews are provided, on the bars b to restrict the travel of the sliding frame to a distance corresponding to the length of the sections being bound. The stapling being completed the. section is drawn from the saddle and towards the front bar b and is' suspended by the tapes while the next subsequent sections are stapled, until, the complete book having been assembled, the tapes are cut close to the bars b and the book is removed for the application of the cover. The tapes may be secured across the sliding frame by pins or spikes h projecting from the tubular members t, the spikes at the front of the machine being protected by resilient covers i, or alternatively, weights may be attached to the front ends of the tapes to serve as tensioning means. The end brace l of the sliding frame is bowed downwardly below the plane of the supporting frame b, c to form a " knocker up " for the book sections when they are on the saddle, thereby ensuring their correct alignment. A handle o for operating the sliding frame is provided on the end brace f.

Abstract: 1,260,188. Transistor oscillating circuits. RCA CORPORATION. 31 March, 1969 [2 April, 1968], No. 16716/69. Heading H3T. In a transistor self oscillating inverter, the secondary winding 46 of a saturable transformer 48 is connected to the bases of a series-connected complementary pair of transistors 34, 36 connected at a given point to the primary 52 of the transformer, the secondary being both coupled to the primary 52 and also connected to be driven independently of the primary, from the given point such as by C54. The transistors operate in push-pull, and energy stored in the leakage inductance of the transformer flows through whichever transistor is conductive, thus preventing the non-conductive transistor suffering reverse bias second breakdown. The resistor chain 38-44 ensures that the single ended inverter will start. The secondary winding 46 may be connected to earth instead of to the emitters of transistors 34, 36 (Fig. 2, not shown), a two potential supply being used, and a resistor chain (92-98, Fig. 7, not shown) may be provided to ensure that the inverter will start. A separate linear output transformer may be used in place of a third winding in the saturable transformer.

Abstract: 1,103,785. Bottling; capping bottles. GRAHAM-ENOCK MANUFACTURING CO. Ltd. 3 April, 1967 [18 April, 1966], No. 16924/66. Heading B8T. Sterilized. liquid, e.g. milk, is supplied to a pre-washed bottle &c., which has been placed upon a pedestal 1 and enclosed within a tubelike container 2 raised by a servo 3 to seat its mouth 4 against the frame of a filling machine, the container and bottle then being evacuated through a passage 7. Next, steam is admitted through the passage 7 to sterilize the bottle &c., and also a bottle cap in a holder 26. The steam is evacuated, and the bottle raised by the pedestal 1 to seat against a filling nozzle seal 18 and open a filling valve 12, thus allowing flow of milk into the bottle. The filled bottle is lowered, and the cap holder 26 slidden inwards to hold the cap over the bottle. The bottle is again raised, to pick up the cap, and then lowered. The tube-like container 2 is lowered to admit atmospheric pressure, which holds the cap on the bottle. Filling nozzles as described are arranged around the usual tank of a revolving table bottling machine. The valve head 12 of each nozzle is fixed and is surrounded by inner and outer telescopic tubes 8, 14, spring-biased downwardly to close the filling valve. The nozzle seal 18 is carried by the outer tube 14. Axial grooves 22 along the inner surface of the outer tube 14 and oppositely-directed U-crosssectioned seal rings 20, 21 coact to prevent the valve being opened by steam pressure and to prevent air from being drawn into the container 2. In the valve-closed position, Fig. 3 (not shown), the lower seal ring 21 surrounds the fixed valve head 12. As the bottle is raised, first lost-motion between the inner and outer tubes 8, 14 is taken up by the outer sleeve abutting a shoulder 25 on the inner tube. With continued upward movement, the inner tube 8 is lifted against the bias of a spring 19, the seal ring 21 is raised above the fixed valve head 12, and the valve is thus opened, to allow flow of liquid from the tank through ports 10 into the bottle.

Filed: 1924-07-17
Abstract: 239,971. Blackburn Aeroplane & Motor Co., Ltd., and Bumpus, F. A. July 17, 1924. Planes, arrangement of.-In monoplanes in which folding wings are divided centrally or are divided from a fixed central portion, the wings are mounted upon fixed oblique axes so disposed that the wings can be turned about such axes from their normal flying positions rearwardly into positions parallel to the fuselage and with their chords vertical, the wings being detachably locked together or to the central fixed portion when iu their flying position. A member 1 supported at its lower end in the fuselage extends upwardly and rearwardly away from the fuselage and is supported at its upper end by stays 2, 3. The upper end of the member is journaled in the wing A which is detachably connected to the wing B along the central longitudinal plane of the fuselage when in its flying position. The front portion of the wing is connected by stays 4, 5 to a bracket pivoted around the lower end of the member 1. The wing may thus be swung about the axis of the member 1 from its flying position to the position shown. Where the wings are carried at the lower part of the fuselage, the member 1 extends downwardly, outwardly and rearwardly from the upper part of the fuselage to the upper surface of the plane. According to the Provisional Specification, the invention may be applied to a biplane having its lower wings smaller than the upper wings. Forwardly-folding wings also are referred to, the member 1 in this case being sloped forwardly instead of rearwardly.

Filed: 1965-04-23
Abstract: 1,085,547. Valves. ACF INDUSTRIES Inc. April 23, 1965 [May 5, 1964; Aug. 10, 1964], No. 17183/65. Heading F2V. A gate valve 10 for underwater use has a bonnet 44 which supports a yoke tube 54 with a filling fitting 55 and a valve-stem packing 72. The tube 54 provides a mounting for an electric or fluid motor driving the valve stem 66 through a worm gear and a nut threaded on the shaft 66. Mounted above the drive mechanism 86 is a pressure-balancing unit incorporating a chamber 104 with a drain fitting 106, a filling means 110 and one or more apertures 114 initially closed by plugs 116. The chamber 104 prevents pressure locking of the valve. With the gate in the closed position the tube 54, mechanism 86 and chamber 104 are filled with a liquid, e.g. transformer oil, which has a lower specific gravity than the surrounding water; the valve is then submerged and the gate opened. Movement of the stem 66 into the chamber 104 increases the pressure therein until at a given level above the hydrostatic pressure of the surrounding water the plugs 114 are blown out and some of the transformer oil is discharged and upon rising to the surface of the surrounding water indicates that the valve has opened. Any subsequent closing of the gate will cause some of the surrounding water to enter the chamber 104 to maintain the pressure in the latter at the same level as the hydrostatic pressure of the surrounding water. Any leakage of controlled fluid past the packing 72 would result in displacement of more transformer oil the appearance of which on the surface of the surrounding water would indicate that leakage had occurred. In a modification (Fig. 3, not shown) the valve stem is disposed horizontally. In another modification, the chamber apertures are replaced by a tube depending into the chamber, the other end of which is outside the chamber and open to the surrounding water and adapted to receive a blow-out plug. This valve may function in conditions in which the outer end of the tube becomes exposed above the surrounding water.

Title: Improvements in or relating to circuit arrangements for automatically terminating x-ray exposures
IPC: H05G1/44
Filed: 1954-06-11
Abstract: 792,051. Photo-electric control of X-ray exposure times. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 11, 1954 [June 16, 1953], No. 17220/54. Addition to 751,786. Class 40 (3). In a circuit arrangement for automatically terminating an X-ray exposure a radiationsensitive indicator disposed behind the subject comprises a number of radiation cells individually responsive to radiation passing through different parts of the subject. The output current of each cell alters the charge on a capacitor connected in the grid circuit of a corresponding discharge tube and the summated anode currents of the discharge tubes operates to cut off the X-rays when it attains a preset value. The invention resides in so arranging the circuit that when the intensity of X-rays on any of the cells exceeds a predetermined average value the corresponding discharge tube is driven to cut off or saturation before the summated currents attain the preset value. X-rays from tube 3 supplied by the mains 20, fall on film 5 after passage through the subject 4 under examination and then produce a light pattern on fluorescent screen 2 corresponding to the local variations of X-ray intensity on the film. The photo-cells 1 are each responsive to light from different parts of the fluorescent screen 2. Immediately prior to an exposure the normally closed switch 16 is opened to charge capacitors 7 to the voltage of battery 10. When the exposure is started the switch is closed but the triodes are cut off by the high negative bias. The resistances of photo-cells 1 are reduced by the fluorescence from the screen in response to X-rays incident on the film 5, thereby allowing current to flow from battery 6 to reduce the charge on associated capacitors 7. The anode current in the triodes 8 rises until when the summated currents exceed a predetermined level relay 13 operates to open the energizing circuit of the X-ray tube. If the intensity of illumination of the film is markedly uneven certain of the capacitors become discharged well before the others but the effect of this high local illumination in the exposure time is reduced by the fact that grid current limits the current in the associated valve so that it is the illumination of the least illuminated parts of the film which ultimately determines the exposure time. In an alternative arrangement the capacitors are uncharged at the start of an exposure and a relay corresponding to 13 is energized to close the supply circuit. On exposure the capacitors are charged to drive the grids negative so that when the total current falls to a preset level the relay releases to open-circuit the X-ray tube supply. In this case the effect of excessive illumination of individual cells is reduced by their being driven to cut-off. The fluorescent screen may be dispersed and cells giving a response to X-rays used instead of the photo -cells.
