Abstract: 672,967. Photographic time recording. BECKMAN, J. C., and WHITLEY, E. M. July 27, 1948 [Aug. 11, 1947], No. 20014/48. Class 98 (i). [Also in Group XIX] Apparatus for photographically recording accumulated time on a continuously moving film in a camera wherein the film is continuously exposed through a narrow vertical slit, comprises a motor driving a counting device to effect the display thereon of numerals corresponding to successive time intervals, means for projecting images of the numerals on to said moving film, and means for-illunlinating the numerals for very short lengths of time at a frequency greater than 100 times per second to prevent distortion of the successive numeral images on the film. As shown, a counter 14 of known type is driven by a constant-speed motor 15 through a shaft 19 with a ten-lobed cam 18 which closes contacts 17 which connect a lamp 16 in parallel with a condenser 20, thereby causing each successive number to be illuminated by a brief flash of light as it appears. The apparatus is mounted in the casing of a camera in which the film 11 moves continuously past a slit 12 in a mask 10, such as a camera for timing races. Light from the numbers, when illuminated by a flash, is reflected by mirrors 22, 26 on to the film 11, whereon an image is formed by a lens system 24, 25. To allow for the time taken for the motor to run up to speed, the numbers may be projected through an opening 27 before the slit 12. Alternatively the opening 27 is abreast of, or a continuation of, slit 12, and the counter starts from a given number, set permanently or by a hand wheel 36 on shaft 19. The motor may be started by a switch 32 operated by electrical means for starting the race. When the contestants approach the finishing line, the film is started and a switch 34 in the lamp circuit is closed. The images of the contestants are recorded on the film in the usual manner together with the numbers which indicate the time in <SP>1</SP>/ 100  sec. intervals for each contestant to complete the course. After recording the finish, motor 15 and the film are stopped, and counter 15 returned to zero, or the number at which it started, in known manner by a lever 35. Specification 537,253 is referred to.

Television apparatus. -An exploring device for a television system comprises two coaxial slotted discs rotated at different speeds and characterized by (1) straight slots in one disc and curved slots in the other disc all extending inwards from the peripheries of the discs or (2) straight slots at different angles in the two discs extending inwards from the peripheries, or (3) the slots in the two discs being such that when their inner ends are superposed, the outer ends meet at or near the peripheries without the slots crossing each other. Fig. 1 shows an arrangement corresponding to conditions (1) and (3). The rapidly rotated disc is provided with curved slots B and the other disc, rotated slowly in the same or the opposite direction, is provided with straight radial slots A. Fig. 3 shows similarly an arrangement cor. responding to conditions (2) and (3). The lightsensitive device at the transmitting station may be in the form of strips of light-sensitive material covering the slots A in the slowly-rotated disc. The strips covering the different slots are interconnected at their inner ends X<1>, and each is provided at its outer end X with a contact cooperating with a segmental collecting contact. If the image to be transmitted covers more than one sector between the straight slots, a corresponding number of collecting contacts, each in a separate transmitting channel, is provided. The discs may be formed of thin opaque material fixed to thin sheet celluloid or other transparent material. Transmission may be effected by the use of infra-red and ultra-violet rays instead of light. An intermediate record of the image may be obtained by converting the fluctuating current into sound impulses and recording these phonographically. A purely local reproduction of the image may be obtained by using different areas of the same pair of discs for the transmitting and re - constituting explorations. Specifications 5339/98 and 218,766 are referred to.
Patent GB-336219-A (GB)
Title: Improvements in or relating to the application of gelatinous films to glass and the like
IPC: B32B17/10
Filed: 1929-07-02
Abstract: 336,219. Barratt, S. July 2, 1929. Coating-machines.-Glass or other material is coated with a gelatinous film, by applying a gelatine-containing liquid by means of a soft bristle brush, uniform relative movement being maintained between the glass &c. and the brush and the latter being continously and uniformly replenished, and drying the film so applied Either the brush or the glass &c. may move. A suitable gelatine solution is one containing about 2¢ per cent of gelatine dissolved in equal parts of alcohol and water. A small quantity of a substance, such as saponin, to reduce surface tension may be added. An apparatus for carrying out the process comprises a number of brass &c. chains 10, stretched on a frame 11 and carried by sprockets 12, so forming a conveyer for the glass sheets 14. The sheets 14 enter a washing chamber 15 where they are washed by jets 16 of hot water, ammonia and steam. A rubber squeegee 17 removes superfluous moisture from the sheets after washing. The dry heated sheets then pass to a coating chamber 18, where a camel hair brush 19 applies the gelatine solution. The brush 19 is fed continuously by capillaries 20 which extend from a tank 21. The gelatine solution in the tank 21 is kept at a constant level bv means of a bird-fountain supply from a reservoir 23, and is maintained at a suitable temperature, e.g. 25-30‹ C. by hot-water pipes 24. The plates then pass to a drying chamber 25 where the gelatine film is rendered hard and dry. In order to maintain the brush 19 free from congealed gelatine when sheets are absent from the conveyer for any considerable interval, the chains are carried around rollers 26, 27. 28 to provide a bight 29 in the conveyer. A roller 30 mounted on an arm 31, which is pivoted at 32 and carries a counter-balance weight 33, projects its periphery slightly above the conveyer level, so as to touch the brush 19 when a glass sheet is absent. The roller 30 is rotated so that its linear speed equals that of the conveyer. The gelatine is thus continuously removed from the brush 19, is scraped off the roller 30 by a. scraper 34, and falls into a trough 35 for subsequent reuse. In order to lower the roller 30 when a glass sheet is present, the glass sheet presses down a light roller 45 which closes a switch 44 thereby actuating a solenoid 43. The armature of the solenoid then pulls the arm 31 (and thus the roller 30) down by means of a link 47. If the roller 30 and its attachments are sufficiently light, no mechanism for removing it from the path of the glass sheets is necessary. The apparatus is particularly of value for coating glass with gelatine films as a preliminary to the manufacture of reinforced glass. Such a manufacture is described in Specification 335,890, [Class 20 (iii), Doors &c.].

Apparatus for carrying out the process is shown in Fig. 1, and comprises a tank 10 of coating material 11, pick-up and doctor rollers 12, 14, transfer and applying rollers 15, 16, and a work-supporting roller 23 dipping into a moistening or adhesive medium 25.  Sheets are delivered from a feeder 33, adhere to the moistened surface of the roller 23 while being coated by the roller 16, are stripped by the stripper 28, and may pass through a drying device 30.  The rollers 14, 15 and 16 are adjustable, and an adjustable flexible scraper blade 27 is provided.  The adherence of the work to the roller 23 may be enhanced by providing its surface with minute depressions 34 which act as vacuum cups, or by providing apertures 36 which successively engage a passage 40, 38, 39 connected with a suction device.  For "strip coating," a number of spaced narrow applying rollers may be provided instead of the single roller 16.  Fig. 6 shows a modification, in which the coating material is supplied to the applying roller 59 from a tank 57, an adjustable roller 60 controlling the size of the puddle 61, while Fig. 7 shows a device in which the coating material is directly sprayed on to the work from a nozzle 71, compressed air from apertures in the chamber 73 producing a very fine spray and also pressing the work against the moistened roller 74.
