IPC: B65H31/32
Filed: 1949-05-11
Abstract: 666,515. Sheet-delivery apparatus. BATTERSBY, J. E., and MASSON, SCOTT & CO., Ltd. April 28, 1950 [May 11, 1949], No. 12588/49. Class 100 (i). Apparatus for stacking sheets of paper board, cardboard, pulp board and like material delivered by a conveyer includes a sheet support comprising rotatable winding means on which can be coiled elongated flexible means such as cables, tapes or the like, anchored at one end, and means for displacing the winding means horizontally beneath the delivered sheets, so that the sheets can be stacked on the support during the removal of previously stacked sheets, the flexible means remaining stationary relative to the sheets resting on it during displacement of the winding means. Sheets are passed from a conveyor comprising travelling tapes 9 and controlling tapes 10 to laying-apparatus comprising a table 14 and an endless band 15 passing over a roller 16 and a jockey roller 17 supported pivotally from a member 18. The bands 15 and tapes 9 are driven by a chain 20. The laying-apparatus is carried on a frame 6 vertically slidable on posts 4 in a hollow column 1. The frame 6 is raised by means of a chain 36 anchored at 39 and operated by a hydraulic cylinder 41, so that as the stack rises, each sheet is delivered to the top. The delivery end of the conveyor 9, 10 is pivoted to the frame 6 by links 8. The sheets are arrested by a plate 21 extending between heads 22 supported by rods 23, 24 from the frame 6. The inner face of the stack is controlled by a plate 25 joggled by means of an eccentric 29. Lateral guide plates, which can also be joggled, may also be provided. In order to allow the stack to be removed without stopping the machine, a temporary support for the sheets is provided. A rotatable winding drum 42 is mounted in heads 44 slidable on the rods 23, 24, and is formed with helical grooves, a plurality of wire cables or like flexible members 45 being anchored to the drum at one end, being coilable in the grooves, and are anchored at the other end to the frame 6 at 46. The drum is rotatable by an endless chain 49 which can be driven from a motor. A pinion on the drum shaft engages a rack 54 formed on one of the rods 24, so that as the drum rotates it also moves horizontally. The cables 45 can thus be moved into position to support the sheets without relative movement between the cables and sheets, the stack below the cables being then removed. With the drum returned to its right-hand position, within the frame 6, while the latter is in its lowest position, the sheets are allowed to rest on the floor to start a new stack. A plurality of bars 57 are carried on brackets 56 slidable on the rods 24, and on the drum is unwound, links 58 passing through apertures in the bars 57 cause the bars to take up spaced positions beneath the cables to provide intermediate support therefor.

Title: Process of producing colour separation record utilizing electro- luminescent material
IPC: G03F3/04
Filed: 1975-03-26
Abstract: 1463935 Producing colour separation records DAINIPPON SCREEN SEIZO KK 26 March 1975 12624/75 Headings G2C and G2X A colour separation record is produced by projecting a colour image on to a photo-sensitive material through a colour separation filter, projecting the colour image on to an electroluminescent member through a colour and contrast compensating filter and energizing the electroluminescent member to project the luminescent image thereof on to the photo-sensitive material in alignment with the colour image. An electrical potential may be applied to the electroluminescent member while it is exposed through the compensating filter. The electroluminescent member may be contacted with the photo-sensitive material before being exposed through the compensating filter. The colour image may be projected on to the electroluminescent member through the colour separation filter before it is projected on to the member through the compensating filter. An electrical potential of a first polarity may be applied to the member while it is exposed through the compensating filter and an electrical potential of the opposite polarity applied to the member while it is exposed through the colour separation filter. Colour separation records of high quality are produced quickly and inexpensively by this process.

Inventor: HOLLINGS CHARLES HENRY
IPC: B24C3/32
Filed: 1918-08-02
Abstract: 130,737. Hollings, C. H. Aug. 2, 1918. Sand-blast.-A hollow article c to be cleaned, such as a shell, is supported on an open rotating carrier b, and means are provided for both raising and lowering the jet nozzle d, Fig. 4, and also for swinging it about an axis d<2>. Two work-supporting carriers b are mounted upon a rotatable platfoim a<2>, which is fitted with ball bearings on a standard a' and is driven bv chain and bevel gearing a<4>, a<5>, a<6> from a main shaft a'. Each carrier b is driven by bevel-gearing b<2>, b<3>, b<4> from the shaft a' during the cleansing operation; the platform a<2> is held stationary, meanwhile, by the engagement of a catch i in a recess i*, the consequent movement of a rod i<2> being transmitted to a clutch i<4> and throwing the gear-wheel a<5> out of connexion with the shaft a<7>. When the article has been cleansed, the catch i is withdrawn and the clutch i<4> thrown into gear by means of a hand-lever i. The platform a<2> then rotates and brings the other carrier into position over the nozzle, where it is locked by means of the catch i engaging a similar recess to i*; or, alternatively, the nozzle d could be swung about d<2> into line with the second carrier b. The nozzle d is carried by a ring-like member d<5> sliding in a frame consisting of a pair of rods d<1>, which, at their upper ends, are pivotally mounted at d<2> to a sliding frame e mounted on rollers e<3> on the main frame, and at their lower ends are carried by the side cheeks d<3> of a bridgepiece d<4>, which also constitutes a coned delivery mouth leading to a hopper h<1> through a flexible connexion h. A hand-lever d<13> working in a quadrant d<14> serves to swing the frame d<1> about the axis d<2>, whilst another lever d<15> working in a quadrant g operates the lazy-tongs series of levers g<1> - - g<12> and d<7>, so as to raise or lower the carrier member d<5>, and thereby the nozzle d. The used sand &c. falls into a hopper j<2>, and thence to a hopper j<3> and through the bellows surrounding the nozzle d into the collecting-hopper h<1>, the upper part of which is slidably mounted on the lower. From here, it passes through a rotary sifter h<2>, where the coarser particles are discharged, whilst the finer material is passed into a hopper f shown in detail in Fig. 5. Air pressure is supplied from a main f<3>, Fig. 2, through a chamber or valve f<2> to the hopper f by means of a pipe f<1>, and the sand &c. is carried under air pressure from the pipe d<9> to the nozzle d. The pipes k<7>, k<8> serve to operate the upper and lower valves k<6>, Fig. 5. of the hopper, the air pressure being so controlled by any suitable mechanism from the shaft a<7> through the chamber f<2> as to open and close these valves alternately and maintain a constant supply of sand to the lowest section, from which it is fed through a valve k<9> also actuated from the main shaft a<7> to the pipe d<9> supplying the nozzle.

Title: Improvements in valve amplifying circuits
IPC: H03F3/66
Filed: 1939-04-28
Abstract: 528,151. Valve amplifying circuits. STANDARD TELEPHONES & CABLES, Ltd. April 28, 1939, No. 12783. Convention date, May 27, 1938. [Class 40 (v)] In an amplifier employing feed-back and preferably of the broad-band type (e.g. 12-60 kc.) the amplitude of undesired oscillations outside the desired frequency band is reduced by a frequency-selective limiter. The invention aims mainly at the reduction of the " singing " amplitude occurring e.g. at 100 or 1,000 kc in negative feedback amplifiers and thus to prevent overloading of the amplifier valves. In the Figure the forward transmitting path comprises a resistance bridge 6 and a chain of amplifiers such as G, P, the negative feedback path f being coupled to the input and output sides of the forward path over hybrid transformers 2, 3. One arm of the bridge 6 is constituted by a limiting device comprising a filter 7 which suppresses the band 12-60 kc, and a non-linear resistance 4 such as Thyrite, a copper oxide rectifier or a valve. For the ranges 0-12 kc, and 60 kc upwards the bridge 6 is balanced at an input amplitude determined and variable by the values of the other arms of the bridge; the output for these frequencies is thus reduced or suppressed while the signal band of 12-60 kc, is unaffected. Low-pass filters 8, 9 may be provided to exclude the " singing " frequencies from the incoming and outgoing circuits. Alternatively instead of a band filter high and low pass filters with separate amplitude limiting devices may be used. In a modification, Fig. 2 (not shown), the limiter device 4, 7 may be connected across the plate circuit of the last amplifier. U.S.A. Specification 1,993,758 is referred to.
