(Also in Group X] Means for erecting building units for the construction of prefabricated buildings comprises metal plates 1 which are bent inwardly at their sides 2 to form slots 3 and screwed at desired intervals along the edges of the building units, interlocking spacing members, such as 7, Fig. 4, being provided with tongues 6 for entering horizontally corresponding slots along the adjacent edges of the building units to hold the latter at the desired predetermined spacing. Alternatively, the plates 1 may be replaced by channel section members each of which is fixed by screws passing through holes in flanges extending outwardly along the opposite edges of the channel with the open sides of the channels opposing the edge of the respective building unit to provide slots extending in the longitudinal direction. The spacing member 7, Fig. 4, is used to connect two building units in line with one another, the tongues on the spacing members used to connect two units disposed at right angles to each other being correspondingly arranged. Spacing members having three, or four, appropriately arranged tongues are employed respectively to connect one unit to two others arranged in line, and to connect two pairs of units disposed at right angles to each other. At the junction of four walls, where the adjacent edges of the units form a closed gap, the spacing members are inserted into the gap from the top by means of an assembly tool which may consist of a bar having a hooked end to engage in holes 10 in the spacing members.
Patent GB-277711-A (GB)
Abstract: 277,711. Armstrong, R. W., and McCabe, I. E. Sept. 20, 1926, [Convention date]. Mercury switches. - The two bulb-like containers 1, 2 are united by a restricted V-part 3 and provided with wells 9, 10 in which electrodes 11 are sealed and a quantity of mercury 12 is placed so as to form a seal between the two bulbs. Normally the pressure in the bulbs is equal but on an increase in that of the bulb 2, the mercury will be forced up the limb leading to bulb 1 and will so close the circuit between the electrodes. The increased pressure is brought about by a bulb 14 of light-sensitive medium which, when subjected to light rays, absorbs certain of them and converts them into heat. A coloured transparent medium is suitable for this purpose. The device may be adapted to open a circuit when subjected to light rays. In a modified form (Fig. 3, not shown) the bulb 2 is filled with broken coloured glass to increase the light-absorbing surface and capacity.

Title: Improvements in or relating to high speed cameras
IPC: H01J31/50
Filed: 1939-10-19
Abstract: 535,081. Image converters. SCOPHONY, Ltd., WALTON, G. W., and WIKKENHAUSER, G. Oct. 19, 1939, No. 28222. [Classes 39 (i) and 40 (iii)] [Also in Group XX] A high-speed camera, capable of taking at least fifty pictures at the rate of ten thousand a second, comprises an image intensifier, an optical system for producing an image of the object on the photo-cathode of the intensifier, a second optical system for forming an image of the fluorescent screen of the intensifier on a lightsensitive stationary surface, means for sweeping the electron image over the fluorescent screen along a path many times longer than the dimension of the image in the direction of motion, and means for periodically applying blanking pulses to an electrode of the intensifier to interrupt the incidence of the electrons on the screen. As shown, a lens 2 forms an image of the rapidlymoving object 1 on to the photo-cathode 3 of the tube 4. Electrostatic focusing rings 6 and an anode 6a focus the plane of the cathode on to a fluorescent screen 5, producing on it an image of the object 1, which image is scanned across the screen by potentials applied to deflecting coils 7, 8. Blanking pulses applied to the first ring 6 periodically interrupt the electron beam, the active periods of which are sufficiently short to avoid blurring of the separate images thus formed, either by the movement of the object or of the beam. The scanning movement of the beam may be uniform, or it may be stepped so that the beam is stationary for short periods, during which the images are formed. The deflection path may be circular, spiral, or a series of parallel paths. The electron beam may be amplified by one or more secondary emitting electrodes in its path.

Abstract: 1502101 Feeding webs IMPERIAL CHEMICAL INDUSTRIES Ltd 24 June 1975 [26 June 1974] 28346/74 Heading B8R [Also in Division F2] A seal device for a continuous web 9, such as used in the process of vacuum transfer colour printing, comprises an enclosed chamber provided with two ports 6, 7, Fig. 1, which when open permit the passage of the web and when closed form a seal around the web and prevent relative movement of the web and closed port, the opening and closing being synchronized such that a seal is maintained by at least one of the ports, Two such seal devices may be used to permit the passage of textile material and transfer paper into and out of an enclosed space at reduced pressure. In operation, the web 9 passes intermittently through a wall 8; when the port 7 is open the port 6 is closed and moves along with the web until the bellows 3, 4 are fully contracted, the port 7 then being closed while the port 6 is opened to permit the bellows to return to their fully extended position. In a second embodiment, Fig. 2 (not shown), the ports (6, 7) are disposed on the ends of respective bellows (3, 4) provided one each side of the wall (8) so that each port can alternately move along with the web. In a third embodiment, Fig. 3, the web 9 is gathered up in a side arm 12 by a roller movable from a position 23C to a position 23D. With the port 18 now closed a pair of jaws 26, 27 now open and a port 16 on a reciprocating unit 15 now closed the unit is moved from position 15A to position 15B and a portion of web is passed through the jaws 26, 27.

Title: Process for rendering textiles water-repellent
IPC: D06M13/248
Filed: 1937-03-31
Abstract: Textile materials of cotton, artificial silk, jute, linen or wool, in the form of loose fibres, yarns or woven material, are rendered water-repellent by treatment with high molecular thiocyanic methyl ethers of the general formula R.O.CH2.S.C­N where R is an alkyl, cycloalkyl or aralkyl radical containing a saturated alkyl radical of at least 10 carbon atoms or the saturated or unsaturated radical of an alcohol of the sterol series, followed by heating.  The ethers may be added to viscose spinning solutions.  Aqueous solutions of the quaternary ammonium compounds of the ethers may be used to impregnate the material, and water-soluble salts of alkalies or alkaline earths with weak acids, e.g. sodium acetate, sodium bicarbonate, potassium cyanate, may be added to the solution to prevent damage to the material when heated.  Crease-proof producing agents, e.g. formaldehyde, with or without urea, an artificial resin such as a urea resin or an initial condensation product thereof, may be added to the solution.  In examples: (1) the quaternary trimethylamine compound of octadecylthiocyanicmethyl ether is added to a viscose spinning solution; (2) a mercerized cotton raincoat material is impregnated at 50 DEG  C. with an aqueous solution of the quaternary pyridinium salt of the same ether, wrung out, dried and heated for a few hours at 90 DEG  C.
