Title: Method of cooling and condensing the crude reaction product of a synthesis of vinyl acetate by the vapour phase reaction of acetate acid with excess acetylene
IPC: B01J19/24
Filed: 1960-06-14
Abstract: <PICT:0892368/IV (b)/1> In a process for the synthesis of vinyl acetate by the vapour phase reaction of acetic acid with excess acetylene, the crude reaction products are cooled and condensed by direct contact with reaction products or a part or component of such products which have been previously cooled.  A preferred apparatus is a conventional cooling tower with countercurrent flow of the coolant which is cooled by usual methods to between -15 DEG C. and 10 DEG C. In an example the crude products containing from 60 to 85 volume per cent. of acetylene at from 200 DEG C. to 50 DEG C. are passed through the cooling tower 2, cooled by a portion of the effluent 4, which is at 30 DEG C. to 80 DEG C. and is further cooled in tower 10 to -15 DEG C. to 10 DEG C. and recycled.  The remaining product 6, is passed to a distillation step for purification and the gas from the top of the tower 3, is recycled to the synthesis stage of the process.

Title: Image reproducing device
IPC: G09F9/37
Filed: 1966-05-11
Abstract: 1,145,877. Monogrammic signs. H. F. RYDSTROM. 11 May, 1966, No. 20840/66. Heading G5C. [Also in Division H4] A contrast signal obtained by scanning or tracing an original pattern is reproduced on the screen of an image reproducing device by moving an air jet nozzle concomitantly with the transmitter stylus over the screen, the screen comprising a plurality of pressure-sensitive devices arranged in a mosaic of recesses in the front surface of the screen. Each of said devices comprises a movable non-black contrast element arranged so as to be movable into two positions, i.e. a bright position in which the contrast element is located adjacent the screen surface and is visible at the front surface, and a dark position in which the contrast element is more remote from the screen surface and is invisible at the front surface. In one embodiment each contrast element comprises an elastic bellows 27, Fig. 2, having a bright coloured front surface, and is arranged in a dark recess which extends through wall 29 of chamber 30 which forms the screen. When a contrast signal is received magnetically controlled valve 18 is actuated and a jet of pressurized air from source 24 leaves nozzle 22 moving bellows 27 from its dark position to its bright position. The image is reproduced in this manner by scanning nozzle 22 over the screen in synchronism with the control signal obtained by scanning an original, and to erase the image an erasing signal is transmitted which in the receiver actuates a magnet coil of erasing valve 20 which connects the chamber to a source 31 of a pressure below atmospheric pressure causing all the contrast elements to return to their dark positions. Instead of a plurality of separate bellows each being airtight secured in a tubular, open-ended recess with dark walls, a thin foil of elastic material (34, Fig. 5, not shown), may be employed which has a plurality of projections and extends between a pair of grids (35) and (36). An external element may be connected to each bellows to protect the bellows against weathering influences. The bellows may comprise a tapered part (39, Fig. 7, not shown), and a spherical part (40) of thinner material, and with this construction multicolour presentation may be provided in that any one of a plurality of differently coloured bellows 41, 42, Fig. 8, may in their bright position entirely fill up the aperture of the contrast device, while in the dark position the plurality of contrast elements accommodate themselves adjacent each other within one and the same contrast device. In such a multicolour system in order that only one bellows is supplied with an air jet a movable plate covers the rear side of the screen having one hole for each contrast device. In a further embodiment, Fig. 9 (not shown), the contrast element comprises a piston or ball.

Title: Improvements in apparatus for regulating electric circuits
IPC: H01F29/10
Filed: 1925-08-22
Abstract: 254,899. Raimondi, F. Aug. 22, 1925. Regulation, automatic; protective arrangements. -An inductance device for limiting currents consists of one or more inductive windings on a core on which is another winding or windings normally neutralizing the inductance of the first winding and adapted. when the current exceeds a predetermined value, to be moved on the core in unison with magnetizable members which are physically independent of the windings and cause a deviation of the flux in the core so that the inductance of the first winding becomes effective and the current is cut down. The Figure shows the device used as a starter between the main switch S and a three-phase motor M. The motor mains 1, 2, 3 are wound on a threelimbed core on which a triple short-circuited loop 8 moves freely. The loop is embraced by two curved, freely movable magnetizable members 9, 9<1> having notched flanges engaging pins 11 in the core limbs so that under the action of the flux at high current values and the simultaneous repulsion between the coils 1, 2, 3 and 8 these members rock from the position shown to that indicated in dotted lines, carrying the short-circuited coils with them. In switching on, the proximity of the coils 8 renders the coils 1, 2, 3 practically non-inductive and there is an initial current which moves the parts to the position shown in dotted lines. The members 9, 9<1> make a flux shunt across the core limbs below the short-circuited coils and this re-establishes the inductance of the coils 1, 2, 3, until the current decreases sufficiently to enable the parts 8, 8, 9<1> to fall. For single-phase use, only the coil 2 and the central short-circuited coil are retained.

A curtain suspension device comprises a track 51 through which slide runners 53 and a drawcord 118 attached to a master runner 56 which is completely contained in the track and is detachably coupled to a runner 53 at the moveable end of a curtain. The curtain is preferably accordion pleated Figs. 1 to 3 (not shown) the depth of the pleats being maintained by flexible spacers (54) of one piece moulded plastics which connect adjacent runners. The master runner 56 which is of rectangular configuration has an internal wall 69 which together with the end-wall 67 forms a compartment within which rides the head of a runner 53. A pulley housing 55 which is situated at each end of the track 51 and engages the head of the runner at the fixed end of the curtain has a cord guide (55) and a pulley wheel (100). The drawcord, an end of which is friction locked about lands 117 in the master runner, passes horizontally as run 118 to the right hand housing where it loops about pulley (100) and returns as run 119 to the left hand housing. The cord 119 drops vertically through slot 113 to a desired operating level and returns through slot 111 to the master runner where the other end of the cord is friction locked about lands 122. The loop for operating the curtains may be moved to the right hand side of the track by catching the loop about the right pulley, slipping this loop through the cord slots 113 and 111 and pulling until the desired operating level is reached. The length of the loop on the left hand side automatically shortens until it is looped about the left hand pulley. The hem (130) Figs. 28 and 29 (not shown) of the curtain contains a flexible sleeve (131) in which a plurality of stiffeners (132), of metal may be placed in an endwise spaced relation.

Abstract: In a process for drying material by centrifuging, the material is subjected to the heating effect of a high frequency electric or magnetic field to facilitate the removal of liquid from the material. A cake of wet rayon is centrifuged in a metal drum, and during the early stages of the process an electrode is introduced into the drum. A high frequency electric current is established between the electrode and the drum to reduce the interfacial tension between the liquid and the rayon to facilitate removal of the liquid by centrifuging or by centrifuging combined with a flow of drying gas. The electrode may be a fixture in the drum, and the circumferential wall of the drum may be perforated and vaned.
