Abstract: 432,635. Kinematograph apparatus. BAIRD, J. L., and BAIRD TELEVISION, Ltd., 58, Victoria Street, Westminster. Jan. 22, 1934, No. 2171. [Class 97 (i)] Two lenses or lens portions are used in taking or projecting, one being stationary, and the other moving, while operative, in a direction corresponding to the direction of movement of the film, Fig. 1 shows a camera in which a fixed lens segment 1 produces an image in a film - frame 3 while the film is still, and a lenssegment 4, reciprocated by a cam 10, produces an image in a frame 5 while the film is being fed through the height of two frames. A shutter 8 is moved laterally by a cam 9 and springs 30 to cover the lenses alternately, and the lenses may be provided with rectangular masks so that the total lens area exposed remains constant during the shutter movement. The periods of film rest and movement may be equal, the lenses may be cut and arranged so that the line joining their optical centres is always parallel to the direction of movement of the film, and a stationary collimating lens may be used in conjunction with the lenses. A modification is described in which the shutter is moved by rotary strikers engaging arms on the shutter. The optical system used in a projector may comprise a condenser 34, Fig. 6, a field lens 36 producing an image of the condenser in the plane of the fixed and moving lenses 13, the image being large enough to cover the moving lens throughout its movement, and a collimating lens 12, the fixed and moving lenses being at their focal distance from the film 35, and the collimating lens being at its focal distance from the screen 26. Figs. 3 and 4 (ii) show details of construction of a projector comprising a stationary lens segment 38 and a lens segment 39 carried by a part-cylindrical mounting 42 on a slide 57 carrying a claw arm 44. A film-pressure pad 40 is carried by the slide, and a pad 41 having no vertical movement is also provided, the pads being respectively operative during the periods of rest and movement of the film. The slide is reciprocated vertically by a cam 63 which is mounted on a shaft 51 and engages a slide 62 carrying a pivot 64 engaging a lever 65 turning about a pivot 66 and jointed to the slide 57 by a slot and pivot 67. The position of the pivot 66 is adjustable by finger-screws 68, 69 to position the slide 57 relatively to the film and to vary the amplitude of movement of the slide 57. The shaft 51 is driven by a motor through worm gearing and carries a cam 55 moving the feed claw 43 into and out of the film, cams 45, 46, respectively causing the pads 40, 41 to engage and release the film, a cam 49 moving the shutter laterally, and gearing 52 driving film sprockets 37, 60. A field lens 71 is mounted on a pivoted carrier to facilitate threading. According to the Provisional Specification laterally separated lenses with prisms or mirrors may replace the lens segments. Specification 381,898, [Group XL], is referred to.

Title: Device for the selection and control of the transmission ratios
IPC: F16H63/20
Filed: 1972-01-17
Abstract: 1369266 Change speed gear selector SOC ANON DE VEHICULES INDUSTRIELS ET D'EQUIPEMENTS MECHANIQUES 17 Jan 1972 [18 Jan 1971] 2220/72 Heading F2D A gear selector shaft 1 is provided with cams 3, 3<SP>1</SP>, 4, 4<SP>1</SP> to engage the heads of gear engaging slides and is moved longitudinally to position the appropriate cam opposite the desired slide which is actuated by the cam as the shaft is turned. A pin 7 is provided to prevent engagement of the highest transmission ratio directly after engagement of one of the lowest ratios i.e. without engagement of an intermediate ratio between the engagements. The pin 7 co-operates with cam surfaces 8, 11, 11<SP>1</SP>. With the pin 7 in the position shown and the shaft 1 in the longitudinal position to engage the lowest ratios V or VI the shaft has to be slid in the direction S to engage a higher ratio and the pin 7 comes into engagement with the cam surface 8 which prevents further sliding of the shaft 1 until an intermediate ratio III or IV has been engaged by turning the shaft which action causes the cam surface 8 to force the pin across the shaft into engagement with the cam surface 11. Further sliding in the direction S can now take place to engage the highest transmission ratios I or II. From the highest ratio the shaft can be slid directly opposite to direction S to engage the lowest ratios since the surface 14 cams the pin 7 back into engagement with the surface 11 so that full direct movement is not prevented.

Patent GB-510320-A (GB)
Title: Process for the granulation of metals, alloys and other fusible materials
IPC: B22F9/10
Filed: 1938-01-26
Abstract: 510,320. Granulating materials. DEUTSCHE GOLD - UND SILBER - SCHEIDEANSTALT VORM. ROESSLER and TRUTHE. W. Jan. 26, 1938, No. 2548. [Class 82 (ii)] [Also in Group III] A method of comminuting molten materials, e.g., metals, metal alloys, metal compounds or slags by pouring them on to a rotating disc is characterised by subjecting the melt to as rapid a cooling as possible by directing a cooling agent as near as possible to the point of impingement of the melt upon the rotating disc, preferably directly on to the said point of impingement, so that the particles are quenched immediately after their formation. The cooling agent may be a stream of gas that serves to prevent too rapid a contact with the surrounding walls, which may be cooled, and the particles may be collected in various fractions in collecting chambers by the method of wind sifting. Examples of gas are nitrogen, carbon dioxide, hydrogen, producer gas, lighting gas or flue gas. Cooling liquids may also be used or cooling liquid and cooling gas may be used together. In certain kinds of melt, e.g., sodium, magnesium, or iron, inert cooling materials, e.g., benzol may be used, and the comminution may take place in an inert atmosphere. The cooling materials may react chemically with the melt. Gases such as oxygen, chlorine, or ammonia, or steam, mixed if desired with inert gas, can be used, and compounds such as oxide of iron or hydroxide of aluminium or zinc chloride or sodium amide can be produced. The reactionable gases, e.g., air, oxygen, steam, sulphurous acid, chlorine, ammonia, hydrogen, carbon dioxide, methane, producer and natural gas or a gas-steam mixture may take the form of an atmosphere in the comminuting chamber. Solid powdered substances such as coal dust, soot, salts, e.g., alkali chlorides may be introduced into the cooling gases and may also be introduced into the melt; or may be mixed with the comminuted material, e.g., metallurgical intermediary product, and the material further worked up. Sulphur or sulphur-containing substances such as sulphides may be introduced before or after comminution of the melt, preferably in quantities 3-10 per cent. The comminuted materials, e.g., oxides, may be collected in liquids to form compounds, e.g., salts. By the use of cooling liquids such as water, or neutral or acid or alkaline solutions the comminuted material may be obtained as a solution or suspension or leach. The comminuted material, if desired mixed with metalloids, carbon, silica, boron, oxides, carbides, sulphides, silicides, pumice, glass, porcelain, and phenol formaldehyde resins, can be pressed and sintered to form moulded bodies. In particular the invention is applicable to gold, silver and the noble metals, copper, iron, nickel, lead, aluminium, magnesium, sodium, alloys, lead glazes, sodium hydroxide, tin and zinc chlorides, ammonium nitrate and naphthalene, glazes, mattes and speiss.
