Title: Tubular insulating currain
IPC: A47H23/00
Filed: 1979-03-14
Abstract: A selectively collapsible and expandable insulating curtain and the method of making same, the curtain having a plurality of collapsible tubes, preferably of plastics material, extending longitudinally for its width and superimposed one on top of the other in a row in the direction of curtain height. Each tube has an upper wall and a lower wall secured together by bands A, B or adhering contact. Additional bands of adhering contact secure superimposed tubes to each other. The side bands of contact define fold lines allowing collapse and expansion of the tubes as the curtain is raised and lowered. In making the curtain, a plurality of thin film strips 82, 92 are wound about the periphery of a forming member F with bands A, B of adhering material interlaminated between adjacent strips, bands A, B between successive adjoining layers being in a staggered relationship. After winding is complete, the superimposed strips are cut transversely, removed from the forming member and straightened to form the curtain. The strips may also be cut longitudinally to provide a plurality of curtains. <IMAGE>

Title: Improvements Relating to Electrolytic Cells
IPC: H01M6/18
Filed: 1979-03-22
Abstract: A solid-state electrolytic cell having a pair of electrodes, e.g. of silver and gold, has these electrodes in contact with opposite faces of a body of electrolyte, e.g. silver iodide, in the form of a thin film of randomly- oriented polycrystalline structure having a grain size of 0.5 microns or less. All the components are produced by successive stages of deposition in vacuo, the conditions of deposition being controlled to give the required grain size. In the example, the silver electrode 2 is first deposited on a glass substrate 1 and the electrolyte 3 is deposited on top of the electrode 2. By starting the deposition of silver iodide before the deposition of silver is stopped, the two layers are dispersed each within the other to form a boundary layer 4. The gold electrode 5 is subsequently deposited on top of the electrolyte layer 3, the deposition conditions being so controlled as to yield a dispersed boundary layer 6. <IMAGE>

Patent GB-2070878-A (GB)
Title: Range finding apparatus
IPC: G01C3/10
Filed: 1980-03-04
Abstract: Conventional binocular range finding equipment designed to scan a field of view is, because of the movement associated with the scanning action, susceptible to detection by hostile radar systems. This problem is avoided in the apparatus of Figure 3 which receives infra-red radiation through apertures 2 and 3 in a tubular housing 19. Scanning in azimuth is achieved by rotating the housing about its axis of symmetry x, this movement being undetectable by hostile radar. Scanning in elevation is performed by rotating a polygonal mirrored drum 11 which deflects images as viewed from 2 and 3 across a detector 14. The spacing of the two images of an object, and therefore the time interval between the detections of these images at 14, is dependent on the range of the object. The aforementioned time interval is therefore measured to give an indication of range. <IMAGE>

Title: Device and method for feeding annular workpieces
IPC: B65G47/14
Filed: 1980-11-20
Abstract: A device for feeding annular workpieces, such as piston rings K, comprises a conveyor belt having hook-shape engagement elements 8. A container for the workpieces is laterally bounded by two discs 2. The conveyor belt forms the bottom of the container and travels upwardly therefrom and about two other discs 3 between which is disposed a funnel for collecting the workpieces dropping from the elements 8 of the belt.

Title: Method of and apparatus for determining angular and transverse displacements of tunnelling machine
IPC: G01C7/06
Filed: 1981-03-26
Abstract: A pipe-jacking tunnelling apparatus and method employed in constructing a tunnel using a shield digging machine enable angular and transverse displacements of the machine and a pipe immediately behind the machine to be determined relative to the predetermined scheduled or central axis of the tunnel to be constructed.

Title: Storage battery electrode of improved specific output and a process and apparatus for the production of the box plate or casing for such electrode
IPC: H01M4/76
Filed: 1982-03-17
Abstract: A boxed plate lead battery electrode characterized in that it is closed on two sides by a respective planar wall 31, 32 continuously bounding all separator compartments between the side walls 38 connecting the two planar walls. The side walls 3 of the compartments are arranged in parallel with the side walls 38 so that they form diaphragms made from strips or threads. The process according to the invention may use fabric or web material. In the case of a fabric-based product the thread walls forming the diaphragms are woven 'in space' into the two continuous walls 31, 32 while the latter are maintained at a height difference corresponding to the thickness of the plate, while in the case of a web or tissue-based product, the two continuous walls are laid one upon another and the side walls 3 corresponding to the compartments are formed by stitching together the two continuous walls with loose stitches employing excess thread of a length chosen in accordance with the desired air gaps in the diaphragm. <IMAGE>

Title: Universal die bolster device
Inventor: MARKIN REGINALD HUGH
IPC: B21D28/04
Filed: 1982-08-25
Abstract: A universal die bolster device comprises a die-holding base, 12, and a back stop 23 and a side stop 16 movable in relation to the base and preferably at right angles to one another. At least one of the back and side stops is vertically adjustable to be movable to at least a position over the centre of the base. Both stops may have provision for vertical adjustment, and adjustment of the shelf member 23B of the back stop and of a shelf member of the side stop allows for trimming-off the surface of a worn die which can then be reused rather than discarded. An ejector sleeve provided under the die or die holder in the base facilitates the removal of the die (holder) by, for example, a tapered drift. A punch carrying a relatively heavily spring-loaded plastics or like pad ensures that the punch is satisfactorily retracted after each operation. An optical measuring arrangement including a reflector removably mounted at the centre of the die holder base, may be provided to translate light transmission times into distances from X and Y axis bases, so that the areas to be punched can be accurately and rapidly positioned. A bridge stripper may be provided for stripping material of the workpiece from the punch. <IMAGE>
