Abstract: 355,831. Self-closing valves. WILSON, N. B., 76, Rainsford Road, Chelmsford, Essex. May 31, 1930, No. 16900. [Class 135.] A valve 6 closing an aperture 5 is opened by rotating a handle 12, and remains open as long as the handle is rotated. The valve is carried by a piston 7 which is supported by links or chains 16 secured to a disc 15 to which the handle is pinned. After the handle has stopped, liquid passes from the inlet port 3 through an aperture 8 to the space above the piston, which, after a time determined by the size of the aperture, descends to replace the valve 6 on its seat.

IPC: D06B19/00
Filed: 1958-06-02
Abstract: A web, yarn or fabric of natural, artificial or synthetic fibres is treated with liquids by continuously drawing a length of the material <PICT:0889210/IV (c)/1> through a vertically disposed column containing a bed of solid discrete particles, which are fluidised by a current of the treating liquid, the liquid being brought to the required temperature by heating or cooling, the said current being in a direction opposite from the direction of feed of the material into the fluidized bed, and squeezing the excess liquid from the material. As shown, a web 1 is passed over a guide roller 2, downwards through a tall thin vertical column 3, under a roller 4 at the bottom of the column, up again through the column, and out between the squeeze rollers 5.  A bed of solid discrete particles, e.g. sand, glass beads or porcelain beads, in the column is fluidised by liquid from the storage tank 8, the liquid being pumped by the pump 7, through the heat exchanger 9, through openings 6 into the bottom of the column. Liquid from the top of the column, together with any solids carried over from the fluidized bed, may be returned to the storage tank and recirculated.  The example describes the dyeing of cotton fabrics by the method of the invention.  The method may also be used for scouring, bleaching, finishing or mercerising.

Apparatus for applying adhesive to a succession of workpieces comprises a chamber supplied with liquid adhesive composition, a generally cylindrical roll which in the operation of the apparatus rotates about its axis with its cylindrical curved surface in contact with adhesive in the chamber and which comprises a recess formed in its cylindrical curved surface extending parallel to the axis, and an adhesive applying blade which extends generally parallel to the axis and which is arranged to move through the recess transversely to the length thereof to pick up adhesive therefrom and then to apply the adhesive to a workpiece. As described with reference to a paper bag making machine, a rod of thermoplastic adhesive is fed into the apparatus where it is melted, the molten adhesive being conveyed to a chamber 4 and thence to the surface of a roll 6 having three radially equally spaced recesses 42 extending the length of the roll parallel to its axis. A bar 46 acts as doctor, wiping the surface of the roll clean while leaving adhesive in the recesses. The gearing is such that applying blade 12 in each rotation about axis 14 enters one of the recesses 42 and sweeps out the adhesive which is then applied to a bag blank.

Abstract: 1465563 A spectrophotometer  SENSORESEARCH CORP 23 April 1974 [23 April 1973] 17643/74 Heading G1A In a spectrophotometer employing neutral cell 20, a sample cell 21 and a reference cell 22 spaced equidistantly from a rotatable shaft 24, light from an incandescent lamp 1 passes via a vibrating double panelled filter, to form two different alternating spectral bands, 14 and a fixed filter 17 to a "periscope" optical arrangement, Fig. 4. On rotating the shaft, the alternating first and second spectral bands of light will pass through each of the cells in sequence to be received by a detector 26 supplying a recorder, an oscilloscope, or an electronic processor. The neutral cell contains a material having a substantially spectrally uniform absorbent over the first and second spectral bands. The reference cell contains a material having a negligible absorption in the first band and a known absorption in the second band. The sample cell which contains the sample, has a negligible absorption in the first band and an unknown absorption in the second band. The description discloses a suitable equation for processing the detector's output signal, wherein the two signals for each cell are ratioed and the result for the neutral absorption cell is compared with the result # for the reference cell and with the result # for the sample cell, the result of the two comparisons themselves also being compared, to arrive at a final result indicating the nature of the material in the sample, i.e. the concentration of a molecular species in a sample. The description also describes Figs. 2 and 4 (not shown) alternative "periscope optics" arrangements.

Abstract: 1,106,637. Semi-conductor devices. BROWN. BOVERI & CO. Ltd. 20 April, 1967 [22 April, 1966], No. 18203/67. Heading H1K. A controlled rectifier consists of a PNP structure in which one of the outer P zones, 2, has a P + region 6 incorporated in one part of its surface, an N<SP>+</SP> region 4 in another part of the same surface, and a common electrode 7 linking these two regions. The resulting structure thus comprises a PNPN + device shunted by a PNPP<SP>+</SP> device. In the N region common to both devices the dopant concentration is non- uniform, such that the inner N zone II of the PNPP<SP>+</SP> device is more highly doped than the inner N zone I of the PNPN<SP>+</SP> device. This ensures that breakdown occurs in the former in preference to the latter device, and the Specification establishes with respect to I-V diagrams (Figs. 2 to 4, not shown) that this property enhances the performance as a controlled rectifier of the structure as a whole. The device is made by: taking an N-type circular wafer in which, by zone refining, the dopant concentration has been made greater in the centre than at the periphery; diffusing P zones 2 and 3 into opposite surfaces; and alloying a circular ohmic contact and a surrounding annular rectifying contact to make the P<SP>+</SP> and N<SP>+</SP> regions 6 and 4 respectively.
