Title: Improvements in photographic film packs
IPC: G03B17/34
Filed: 1929-12-31
Abstract: 352,429. Photographic film - packs. GEVAERT PHOTO-PRODUCTEN NAAMLOOZE VENNOOTSCHAP, Oude God, near Antwerp, Belgium. Dec. 31, 1929, No. 39883. Convention date, Dec. 31, 1928. Void [Published under Sect. 91 of the Acts]. [Class 98 (i).] A pack of the kind in which films provided with pulling-tabs of different shapes are drawn individually, by pulling on these tabs, from a front exposure compartment, round the end of a partition plate, into a rear storage compartment is characterized mainly in that the grip points of all the tabs lie in the central transverse plane of the pack. In a preferred form, the tabs are alternately of different colours, the number of each is impressed thereon more than once, and a portion of each tab is cut away, preferably in such a position as to disclose one of the numbers on the tab next below it, the object in view being to minimize the risk of pulling two tabs at the same time. As shown in Fig. 9, tabs having a central grip point are cut away as at 3, alternately on the left and right. Each tab bears its number twice, and one of the numbers is so printed that it is visible through the cut-away part of the tab above it. The numbers on the tabs may be printed in colours which differ or alternate from tab to tab. Fig. 8 shows a pack in which alternate tabs having a central grip point are cut to distinctive shapes.

Title: Improvements in or relating to the formation of metal coatings
Inventor: JENKINS WALTER NORMAN
IPC: C25D13/02
Filed: 1961-11-08
Abstract: <PICT:0945907/C3/1> In coating metal sheet or strip with metal powder electrophoretically from a suspension of the finely divided coating metal and then heating the deposit under pressure to render the coating adherent, e.g. as described in Specification 884,797, the thickness of the coating is in inverse proportion to the thickness gauge of the substrate metal, whereby a uniform thickness is obtained on compaction in the subsequent heating and rolling stage.  The variation in the thickness of the deposit may be effected by forming a series of strip anodes 16 hinged together into a curved surface as presented to the substrate strip 11.  The position of the anode strips is determined by control rods 18.  In other forms, (a) the anode strips are insulated individually, and are connected to separate power sources which can be varied, e.g. by an automatic control operated by photo-cells scanning the thickness of the deposit, (b) a screen in the form of strips is interposed between the anode and the strip, the position of which strips may be adjusted.

A multiplication device forms all the partial products of the several pairs of digits in the multiplier and multiplicand and collects the relevant partial products to form the final product, use being made of electric selectors and printed circuits. First embodiment. In a wage calculator the number of hours is set up on levers 16, 17, Figs. 1, 2, which rotate plunger boards 14, 15. The rate per hour is set up on a bank of switches 19 by push-buttons 20. Spring-loaded plungers on boards 14, 15 bear against printed circuit boards 12, 13, one line of plungers for each sectoral region, Fig. 6. The contacts of the collector are printed as shown in Fig. 4. The collector has a rotary switch for each digit, the pence switch being shown in Fig. 8. The pence coil of the register is energized each time circuit is made between slip ring 44 and a contact 31-41. Pin 62 effects carry, Fig. 10, by causing a metal stud to bridge two contacts 64. The carry levers 59 are restored between successive collector cycles. Second embodiment. Each partial product is computed by a double-sided printed circuit. Figs. 21, 22 show the units and tens sides of a circuit for multiplying digits up to 5. Depression of a button 82, Fig. 20, permits spring- pressed balls 90, Fig. 23, to make electrical contact in the related column.

Title: Fluoro-organic acid catalyzed condensation process for producing organosilicon polymers
IPC: C08G77/00
Filed: 1960-12-06
Abstract: In making an organopolysiloxane by condensing a compound of the formula: <FORM:0943607/C3/1> wherein each R is a monovalent hydrocarbon radical (saturated or unsaturated) with or without halogen, hydroxyl, cyano, alkoxy or aryloxy substituents, R1 is H or an alkyl radical and n is at least 1, a fluorine-substituted aliphatic acid is used as the condensation catalyst.  Catalysts specified are mono-, di-, tri- and chlorodifluoroacetic acids; 2-fluoropropanoic, 2-fluorobutanoic, 2,3-difluoropentanoic, fluoromalonic, perfluorosuccinic and perfluoroglutaric acids. The process, which may be effected in an inert organic liquid, is generally conducted at 25 DEG  to 170 DEG C., and the by-produced water or water and alcohol is preferably continuously removed, the catalyst being removed from the end-product, if desired, as by washing with water.  The linear products may be end-blocked by reaction with a trihydrocarbon halosilane.  In a modification, alkoxysilanes RrSi(OR1)4-r, where r is 1, 2 or 3, and R1 and R are defined above, and in addition, R may be gamma hydroxypropyl, are co-condensed with the starting organosilicon compound to yield diorganosiloxanes containing functional radicals uniformly spaced throughout or at the ends of the siloxane chain.  In a typical example (1) HO[(CH3)2SiO]20H was heated with CF3. COOH to yield a siloxane gum free of low molecular weight cyclics. The products may be cyclic siloxanes, siloxane gums or siloxane oils.

In an atomizing nozzle, in which a spring- loaded needle 6 displaceable axially of the nozzle and connected to a piston 9 is mounted in so as to close a central opening m of a central opening of the nozzle outlet surrounded by an annular opening n, and in which the opening stroke of the needle is effected by fluid under pressure acting on the piston, there is an elastic tubular partition 14 loosely surrounding the upper shank 6a of the needle 6 and being arranged to effectively seal a chamber conveying the material to be atomized from a chamber receiving the gas under pressure for actuation of the piston. The partition 14 makes a sealed connection with piston 9 and with member 15, and is stretched or compressed on movement of the needle 6. Medium to be sprayed enters at connection 4 to chamber a then into annular space b in the interior of bushing 3 to the outlet orifice m. Compressed air for atomization enters at connection 5, passes via chamber c to annular opening n. Compressed air, to actuate the piston and open the needle valve against the closing pressure of spring 10, enters at connection 13 and passes via opening 12 to chamber e. Adjustment of threaded stud 18 determines the extent of the backward movement of the needle and regulation of the gas pressure on the piston determines the position of the needle point relative to opening m. Inlets 11 communicate the space behind the piston to the atmosphere. One purpose of the needle is to clean the outlet orifice. Alternatively the spring 10 may be omitted and the resiliency of the partition may provide the closing force.

As shown, there are five screens fixed in a steel shell 4 one below the other arranged in order of diminishing mesh size. The shell is suspended by coil springs 5 and is vibrated by two out-of-balance electric motors 18. The bed of particles produced on the strand 2 finally passes under a cut-off plate 28.
