Title: Improvements in or relating to the reproduction of images from lenticulated films
IPC: G03C7/14
Filed: 1930-04-02
Abstract: 343,369. Colour kinematography. TECHNICOLOR MOTION PICTURE CORPORATION, 110, Brookline Avenue, Boston, U.S.A.-(Assignees of Kalmus, H. T. and Ball, J. A.; 110, Brookline Avenue, Boston, U.S.A.) April 2, 1930, No. 10469. Convention date, April 3, 1929. [Class 98 (ii).] Kinematograph films, each bearing a series of colour record images of one colour, are produced from a lenticular screen film by separately reproducing each colour record in a distinct layer of emulsion, which may be treated, e.g. to produce a printing matrix, independently of the records of the other colours. The original film N is projected on to a blank film P by means of a lens O having an effective aperture at least as small as that of the taking lens and a rear focal distance equal to the front focal distance of the lenticulations 1, a mask 3 being provided to cover all except the record of the colour to be reproduced. It is stated that the records may be produced in separate layers of the same emulsion or a tripack used without the mask.

Title: Improvements in and relating to vulcanizing processes and apparatus for the manufacture of high pressure expanded vulcanized rubber and like substances
Filed: 1920-04-15
Abstract: 162,176. Marshall, C. L. April 15, 1920. Porous or spongy india-rubber, etc.; vulcanizing-chambers; plastic compositions containing india-rubber and resins, waxes, &c. - In the manufacture of porous expanded india-rubber by vulcanization in an inert gas under high pressure, a wax or resinous substance, such as ceresin is added to the ingredients to minimize the diffusion of gas from the spongy mass. The wax or resin may be omitted from the outer layer, which then gradually loses its gas and forms a resilient skin which prevents excessive expansion of the interior mass. The ingredients are placed in a shell 1 surrounded by an outer vessel 8, which is provided with a heating-jacket 15. Compressed gas is admitted to the vessel 8, and when a certain pressure is attained adjustable automatic valves in the passages 6 admit the gas to the inner shell. Heat is then applied, and temperature and pressure are gradually increased to the maximum values of about 305‹ F. and 75 atmospheres. When vulcanization is complete, the temperature is first somewhat reduced and then the vessel 8 is rapidly exhausted. The automatic valves at 6 retain a pressure of about 100 lb. in the shell 1, which is allowed to remain until the product has cooled and is then released. A mixture of rubber and balata may be substituted for pure rubber if desired, but the proportion of rubber should not be less than onethird.

Title: Dual price selective bottled beverage vending apparatus
IPC: G07F9/00
Filed: 1972-03-08
Abstract: 1327916 Coin freed vending apparatus VENDO CO 8 March 1972 [9 Nov 1971] 10681/72 Heading G4V Vending apparatus which has a set of article vending stations 26 with corresponding article retaining means 12 for normally blocking vend ing therefrom includes master locking means for locking all of the retaining means in their blocking positions and subordinate locking means associated with only those of a sub-set of the retaining means for normally preventing shifting of the retaining means into a vending position, even when the master locking means are released. As described the articles are bottles fed by inclined shelves 14 to openings 26 in panel 24 through which the bottles may be manually withdrawn when article retaining gates 12, having rollers 30 riding on the necks of the bottles, are freed for rotation. The master locking means are released upon the deposition of a certain value of coinage and the subordinate locking means on the deposition of further coinage, thus enabling the apparatus to vend bottles at two prices. A spreader 36 is fixed to a pivot pin of each gate 12 and on shifting of the gate when a bottle is withdrawn the arms of the spreader engage surface 72 on the lower adjacent captive link 38 and a surface 86 on the higher adjacent link 38. The lowermost link (42) (Fig. 1, not shown) is normally prevented from downwards movement by a bolt (44) but is freed by means of a solenoid (52) when the required lower value of coinage is deposited. Simultaneous rotation of two spreaders is prevented by means of the engagement of the lower spreader with the surface 86 of the link 38 above it, and sequential vending of more than one bottle from a single coinage deposit is prevented by a common bar 50 having concavities 88 for receiving the left end of any spreader rotated, and which is moved downwardly by the first spreader rotated. The subordinate locking means comprises an element 100 pivoted about a vertical axis which carries releasably attached members 118 with turned in tabs 122 (see also Fig. 3, not shown), the element 100 normally being urged such that the tabs 122 engage the right ends of the spreaders 36 with which they are respectively associated. A solenoid 124 is energized on the deposition of the required further coinage to move the element 100 from its blocking position, thus allowing vending from those stations with which the members 118 are associated. U.S. Specification Nos. 2,766,906 and 2,898,001 are referred to.
