Title: Total de-salting of water
IPC: B01J47/14
Filed: 1953-05-12
Abstract: 738,876. Purifying water. SULZER FRERES SOC. ANON. May 12,1953 [June 11, 1952], No. 13197/53. Class 46. A method of reducing the effect of transitory temperature fluctuations in the water supply to a plant performing total de-salting of water comprises mixing the water supply with the contents of a water reservoir and feeding the plant from the reservoir. The invention includes apparatus comprising a reservoir to which the water to be totally de-salted is supplied, a mixing device in the reservoir and a plant for total desalting which is supplied from the reservoir. In one embodiment (not shown) the water. being supplied to the de-salting plant through a reservoir (having a mixing device) passes first through a valve controlled by a temperaturesensitive element located between the reservoir and the plant. As shown, water entering at 3 is cooled at 4 by heat exchange with cooler water leaving the plant 2 before passing to a reservoir 1 having a mixer 6. More cold water from a pipe 5 may be added either to the water from pipe 3 entering the reservoir (pipe 7) or directly to the reservoir (pipe 8) or between the reservoir and the plant 2. A valve 11 in the pipe 3 may be controlled by a heat-sensitive element 10. In Fig. 3 (not shown) condensate derived from the exhaust steam of a turbine is first cooled by heat exchange with cooler water from the de-salting plant and is then further cooled in a second heat exchanger before passing to the reservoir, where it is mixed with the contents, and thence to the de-salting plant.

Abstract: 135,212. Schroder, E. June 8, 1918, [Convention date]. Addition to 133,700. Welding.-In a modification of the) electric seam-welding machine described in the parent Specification, the tube is fed between a fixed mandrel electrode and an external roller electrode by a step-by-step motion so connected with a switch that the current is on only during the period of rest of the tube or a portion of that period. The seam is open behind the carrier 11 of the mandrel electrode and is closed in front thereof by pressing rollers. The tube is gripped by tongs 5 on a moving rack 4 fed step-by-step by a pawl lever 3 operated by a cam 2 on the shaft 1. The shaft 1 carries an adjustable segmental switch to put on the current during the period of rest. The upper electrode A is freely mounted on a pivoted arm which is operated by the cam 2 so that pressure is on only during the period of rest. A roller 9 carried by a pivoted arm is raised by the cam 2 or a second cam so as to raise the tube from the mandrel during the feed motion. The tube is raised into contact with the roller electrode so as to rotate it to provide a fresh point of contact for the next weld. The mandrel may be internally cooled. The Specification as open to inspection under Sect. 91 (3) (a) describe modifications in which the seam is closed when fed into the machine. As shown in Fig. 3, (Cancelled), the tube moves over a short hardened-steel mandrel 16, not connected to the welding circuit, and is supported by a roller 23, and current is conveyed by electrodes 14, 15, the electrode 15 performing the welding operation. In a moification, the electrodes mav be arranged' at opposite sides of the seam and a third roller of steel &c. along the seam to complete the weld. In a further modification, the rolls on opposite sides of the seam may be connected to one pole and the seam roll to the other pole. The seam in this case has upstanding edges. The mandrel in these forms is mounted on a long rod of length equal to that of the tube, and may be made of good conducting material surrounded with an in. sulating layer. It is also stated that in all formsthe external rolls may be replaced by contact jaws which grip and release the tube in time with the step-by-step motion. The mandrel used in the first form is also stated to be rotatably mounted and also to be movable longitudinally to bring a fresh portion under the welding point. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the production of cartoon motion picture films
IPC: G03B15/08
Filed: 1940-05-03
Abstract: 541,773. Cartoon kinematograph films. GABOR, D. May 3, 1940, No. 14092/41. Divided out of 541,752. [Class 97 (i) and 98 (ii)] Cartoon films on lenticular bases, capable of giving a stereoscopic effect when projected on to screens such as are described in Specification 541,751, are produced by the use of apparatus as hereinafter described; the films may have half-tone or multi-coloured images. As shown in Fig. 7, a light source 83 and condenser 84 project a beam through a colour filter 82 covering a slit 81, the beam being reflected by a semitransparent mirror 80 on to a lenticular plate 77 having light-sensitive material glued to its back. A filter plate 78 having a small hole 79 is connected by a pantograph or the like to a pencil or handle usable by an artist operating as an " animator". The fan-shaped beam passing through the hole 79 blackens the sensitive material and thus serves as a "pencil" to produce a cartoon picture thereon ; the directions of the lenticular axes and of the fan-shaped spread of the beam form an acute angle so that images of the nature described in Specification 541,752 are formed. These images are binocularly viewed by the animator through a slit 75 having a lens 76. The filters 82, 78 are coloured so that the light passed by the filter 82 is stopped by the filter 78, and the material on the plate 77 is sensitive to the light passing through the hole 79 and insensitive to light providing the illumination behind the plate 77 to render the image visible to the animator. The action pictures alone may be produced on the plate 77, previously drawn background pictures being provided on a lenticular plate 85 viewed simultaneously with the plate 77, by means of a mirror 86 and the mirror 80; masks for the overlapping parts of the two pictures may be provided. The drawn pictures may be photographed through the slit 75 by a camera having lenses as described in Specification 541,752. Half tones may be rendered in the pictures by the use of a narrow slit parallel to the lenticules in place of a small circular hole 79, the depth of tone being controlled by speed of drawing and by the intensity of the light source. Alternatively, the sensitive material may be such that when exposed to light action it will take greasy paint, and the area boundaries alone may be drawn, the areas being filled in with water colours. Similar methods are described for the production of multi-coloured pictures. According to the Provisional Specification an additional mirror may be provided, e.g. parallel to the mirror 80, since the visible background image is a mirror image of the background picture, and the background may be drawn with the same apparatus.

Abstract: 1,108,806. Communication systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. 5 April, 1965 [I Sept., 1964 (2)], No. 14260/65. Heading G4A. A communication system for linking a computer with input/output devices (e.g. punched card, magnetic tape, real time devices) comprises a first and a plurality of second information handling terminals, the first terminal (associated with the computer) including means for providing addresses, commands and data to out lines connected to the second terminals, each second terminal (associated with input/output devices) including means for providing addresses, status information and data to a plurality of in lines connected to the first terminal, and the out and in lines having at least one associated tag line energizable to indicate the nature of the information currently being provided to the associated lines. The particular embodiment is similar to those of Specifications 1,108,804 and 1,108,805 which are referred to, but the description is more detailed regarding mode of operation and Figs. 4A-4K (not shown) provide detailed flow drawings of the mode of operation. Delays are provided during (parallel) information transfer for deskewing purposes. The first terminal selects a second terminal by providing its address. If no second terminal recognises this address as its own, an error indication is given (Fig. 4D, not shown). All input/output devices are reset when both an " operational out " line (otherwise used for interlocking purposes) and a " suppress out " line are down. If " suppress out " is up when " operational out " drops, only the input/output device in operation on the system resets. Presentation of status information to the first terminal is prevented if the " suppress out " line is up, as is data transfer involving non-cyclic input/output devices, i.e. those that can wait for transfer without overrun (e.g. buffered devices). The " supress out " line is also used for indicating " command chaining," i.e. a succession of operations initiated by the first terminal at the same second terminal. Input/output devices may be time-divisionmultiplexed on to the lines communicating with the first terminal, each device allowing another device to acquire the lines after dealing with one unit of data only (" multiplex mode "), or alternatively an input/output device may deal with a block of data before losing the use of the lines (" burst mode ").
