Title: Filamentous mat and method of making such mat
IPC: D04H3/07
Filed: 1961-03-23
Abstract: 906,811. Filamentous mats. AMERICAN AIR FILTER CO. Inc. March 23, 1961 [March 30, 1960], No. 10638/61. Class 140. A method of making a filamentous mat comprises forming a condensed filamentous planar mat of a series of overlying layers, each layer including substantially straight, transversely spaced, continuous filaments, with the filaments of adjacent layers lying in a crossing relationship, stretching said mat in a transverse direction relative to the general lay of said filaments to simultaneously elongate said mat and expand it in thickness, and then selectively severing the filaments forming said elongated expanded thickness mat at laterally and longitudinallyspaced intervals as the mat is advanced, and flattening and applying a binder to said selectively severed mat. As shown (Fig. 1) a cylindrical condensed mat is made by feeding a plurality of glass fibre filaments 2 issuing from a glass furnace 4 on to the surface of a rotating drum 6. The furnace 4 and fibre grouping means 8 are driven in a reciprocating path axially back and forth between the ends of the drum whereby successive layers of mat are built up. Some of the fibres are gathered by means 8 to form ribbons for deposition on the drum. The completed mat is slit axially, removed from the drum and laid upon a flat surface to form a planar mat 10 (Figs. 3 and 4) which is then stretched to form an expanded thickness web 14 of reduced width. Web 14 then passes between superposed mat piercing rollers comprising upper toothed roller 16 and lower smooth roller 18 and thence passes over flat inclined support 20 on to endless conveyer 22 on which it is carried into bath 24 of binder liquid, passing under roller 26. Upon emerging from the bath at 28 it passes over suction device 30 whereby excess binder is removed, and then through oven 32 wherein the binder is cured and is finally wound on roll 34. Roller 16 is provided with spaced teeth 36 extending in axial rows along the rolls and in circumferential rows around the roller. Flat metal bands 38, supported at each end, are disposed in downwardlybowed fashion through the gap between the axially-spaced rows of teeth to prevent fibres from winding on to roller 16. Rotating wire brush roller 40 wipes from roller 16 any fibres which may escape bands 38.

Title: Controlling and indicating apparatus for physical magnitudes
IPC: G05D23/22
Filed: 1940-06-22
Abstract: 542,962. Automatic control systems for variables in general; correspondence control systems. STEGHART, F. L. June 22, 1940, No. 10763. [Class 38 (iv)] [Also in Group XXXVIII] Temperature &c.-The value of any physical magnitude is controlled and indicated by causmg it to generate or regulate an electric current or voltage which is amplified by a thermionic valve and fed to a measuring instrument, the moving element (coil or iron) of which operates an indicator or recording pen and actuates means controlling the magnitude. As shown a thermocouple 1 co-operates with a galvanometer 3 and photo-electric cell 16 to vary the phase and magnitude of the potential of the grid of gas filled valve 10 energized by A.C. The rectified output of the valve passes unsmoothed through a resistance 7 common to input and output circuits to oppose the thermocouple e.m.f. and stabilize the amplifier to proportional output. After smoothing, the output current passes through a moving coil instrument 11 driving a recording pen 13. A spring controlled contact flapper 29 engages an adjustable contact 34 until the temperature has reached a predetermined value whereupon a Ferraris motor coil 38 is de-energised to reverse the drive to a friction coupling 39 and tilt a mercury switch 40 whereby a switch 69 is opened to interrupt the current supply to the furnace. A resistance thermometer 26, in a bridge circuit comprising a resistance 4a in series with the thermocouple, may correct for variations in temperature of the cold function. Modifications are described in which the arm 29 cooperates with the nozzle of a standard fluidpressure control system and in which the mercury switch is operated by an electromagnet controlled by disc contacts rotated by the instrument with a retaining circuit controlled either by an auxiliary disc contact set to open at a slightly different temperature or by an intermittently operating interrupter. A slide wire may take the place of the resistance 7 and the thermocouple circuit may include a potentiometer resistance whereby the controlled temperature may be adjusted. A disc contact rotated by the measuring instrument may control the electromagnet to cause cessation of furnace heating if the thermocouple should break and under excess temperature. conditions. The controller may move an iron element in a magnetic field to work a relay. Specification 537,784, [Group XL], is referred to.

Abstract: 1,128,019. Rotary-piston internal combustion engines. YANMAR DIESEL ENGINE CO. Ltd. March 11, 1966 [March 13, 1965], No. 10823/66. Heading F1F. A rotary-piston I.C. engine of the type comprising a casing having a two-lobed epitrochoidal inner peripheral profile and a rotary three-sided piston planetary rotatable therein and having apex seals at its corners controlling the opening and closing of peripheral suction and exhaust ports, includes a regulating valve 1, Fig. 1 of part circular cross-section in the suction port 7 which at low engine speeds partially closes the suction port on that side thereof adjacent the exhaust port 9 thereby reduce the period of overlap between the suction and exhaust ports. At high engine speeds the valve is retracted into a recess in the engine casing to fully open the suction port. The regulating valve which is jointly operable with the engine throttle reduces under low speed operating conditions the amount of overlap in the opening of the suction and discharge ports to prevent the back-flow of exhaust gases into the suction port and the development of negative pressure in the exhaust port, which negative pressure in the case of an engine used for marine propulsion could induce water into the engine.

Title: Production of photographic plates for use in the manufacture of electrical circuits
Inventor: MASSEY PETER GRAHAM
IPC: G03F7/20
Filed: 1968-03-07
Abstract: 1,254,544. Fascimile apparatus. JOSEPH LUCAS (INDUSTRIES) Ltd. 3 Feb., 1969 [7 March, 1968], No. 11089/68. Heading H4F. [Also in Division G2] In the production of a photographic plate for use in the manufacture of electrical circuits, a sheet of material is divided into rectangles and the pattern 18 to be imaged on to photographic material 19 is drawn by filling in the appropriate rectangles. These rectangles are scanned in turn by a light source 25 which projects a beam of light at one rectangle after another. If the rectangle is not filled in reflected light falls on a photo-cell 26, the output of which will prevent the energization of an exposing lamp 21. If the rectangle is filled in, there is no output from the photo-cell 26, so the lamp 21 is energized and light therefrom passes through a rectangular aperture 22, and thence via a mirror 23 and lens 24 on to the photographic material 19. The pattern 18 need not be drawn with great accuracy for if part of an adjacent rectangle is filled in inadvertently when filling a particular rectangle, the partial filling will be ignored because there will still be sufficient light reflected from the partially filled in rectangle to obtain an output from the photocell 26, and hence no energization of the lamp 21. The members 21-24 are carried by a block 15 positioned above the photographic material 19, and the members 25, 26 by a block 16 above the pattern 18. The material 19 and pattern 18 are carried by a rotatable drum 12 which is stepwise rotated in response to signals from an encoder 13. The blocks 15, 16 are interconnected by a sleeve 17 and are moved axially as the drum 12 rotates. This means that there is relative helical movement between the blocks 15, 16 and the drum 12, so the rectangles must be drawn so that when mounted on the drum, they extend in the required helical path in order to ensure their scanning in turn. The timing of signals from the encoder 13 is controlled to allow for the relative helical movement.
