Title: Apparatus for splicing and cutting kinematographic films
IPC: G03D15/04
Filed: 1962-03-28
Abstract: 940,902. Film splicers. G. H. LAPERSONNE. March 28,1962 [March 31,1961; July 18, 1961], No. 11891/62. Heading G2C. A film splicer has a single control lever, the operating of which produces, in succession, the trimming to length by a cutter of the two film ends to be joined, the returning to co-planar relationship, after displacement by the cutter, of the said two ends, the application of an adhesive strip round the said ends, the cutting off of the adhesive strip from a supply roll, and the punching open of the perforation covered by the strip. In the form shown, the two films 6, 7 whose ends are to be joined are carried in channels 2, 3, and located between lugs 8 and on studs 4, 5. The channels form part of a base plate 1, to which is also secured a pillar 17. On the pillar is mounted, by spindle 18, a spool 15 of adhesive strip material 16. Also mounted on pillar 17, by a pivot 20, is a control lever 21, whose lower end has a slot 23. Adjacent this lower end is a slotted guideway member 27, and adjacent again is lever 28 which carries the knife 38 which trims the film ends. A spindle 26 passes through slot 23, and slot 25 in guide member 27, being finally secured to lever 28. This lever is also pivotally secured to a spindle 29 which can move in an extension 30 of slot 25,and also engages the end of a slider 31. This slider carries a small plate 33 which projects through a slot in the plate 1 to form a support for the film ends when they are trimmed. Fig. 2 shows the apparatus when ready for operation. The adhesive strip 16 is fed forward, and rests on a part 34 of the knife-carrying lever 28, held in this position by a spring-loaded blade 36. Depressing control lever 21 causes spindle 26 to move down guide slot 25, and hence pivots lever 28 downwards. This brings the knife 38 down to cut the film ends. At the end of this downward stroke, one arm of a V-shaped lever 39 pushes up the cut end of film 6 back to its original position. Further depression of lever 21 now causes spindle 26 to move along the horizontal portion of slot 25, so that both lever 28 and slider 31 move back together. As the plate part 33 of the slider moves back, it folds the end of the strip 16 round under the film, so that the strip now extends both above and below the film (Fig. 13). Further depression of lever 21 into its lowermost position (Fig. 7), when it is now acting against a spring 45, brings down a small knife 44 attached to it which cuts through the adhesive strip 16, severing it from the remainder of the reel, while at the same time a pin 47 punches open the film perforation where it has been covered over. Figs. (not shown) 17-19 illustrate an alternative means, instead of lever 39,for pushing up again the cut end of film 6.

Title: Manufacture of organic hydroperoxides
Inventor: HALL REGINALD HAROLD
IPC: C07C409/12
Filed: 1954-04-24
Abstract: The process of the parent Specification is modified in that the feed of diisopropylbenzenes which is oxidized to the dihydroperoxides, is substantially free from trimethylindane and o-diisopropylbenzene, and is produced by the alkylation of benzene or cumene, or by the disproportionation of o-diisopropylbenzene or poly-isopropylbenzenes, in the presence of aluminium chloride as catalyst, and under reaction conditions whereby substantially no trimethylindane or o-diisopropylbenzene is produced.  The interrelated factors required to achieve, either by alkylation or disproportionation, a feed as defined above, are reaction temperature and amount and type of catalyst.  The specified temperature range is about 40-115 DEG  C., the reaction time and amount and type of catalyst being adjusted accordingly.  The specified amount of catalyst is between 0.1 and 12 mols. per mol. of benzenoid material.  The aluminium chloride catalyst may be activated by treatment with hydrogen chloride or isopropyl chloride.  A liquid ternary complex alkylation catalyst, prepared for example by agitating a mixture of 1 mol. of mono- or poly-isopropylbenzene and 1 mol. of aluminium chloride while adding half a mol of isopropyl chloride, is preferred.  The alkylation is carried out on benzene or cumene using as alkylating agent n- or iso-propanol, isopropyl chloride, or preferably propylene.  In examples: (1) cumene was alkylated with propylene at 60 DEG  C. using unactivated aluminium chloride as catalyst, to give a feed consisting of m- and p-diisopropylbenzenes and almost free of trimethylindane, and this feed was oxidized by the process of the parent Specification, the result being compared with that obtained with a feed containing 11 per cent of trimethylindane; (2) benzene was alkylated with propylene at 60 DEG  C., using a catalyst prepared by passing hydrogen chloride through a mixture of aluminium chloride and cumene, and the product analysed; (3) benzene was alkylated with propylene at 80 DEG  C. using unactivated aluminium chloride as catalyst and a mixture containing mono-, di- and poly-isopropylbenzenes was obtained, the di-isopropylbenzene fraction being free of the o-isomer and trimethylindane.  A table is given showing the effect of various reaction temperatures on the composition of the alkylate, when using the procedure of (1).

[Also in Groups XXVIII and XXXIII] In a system of controls in which each of at least two tension links includes a disengageable connector including two mating parts which lie alongside one another and are held together by a surrounding member, the adjacent surfaces of the mating parts being formed with projections and recesses interengaging to prevent relative longitudinal movement, the distribution of projections and recesses of one connector is different from that of any other so that the controls cannot be interchanged. In part of a control linkage for an aircraft, two oppositely acting tension cables A, B, Fig. 1, are respectively connected by separable connectors A<SP>1</SP>, B<SP>1</SP> to chains A<SP>2</SP>, B<SP>2</SP>. Referring to Fig. 2, the mating parts C, D of each connector are generally semi-cylindrical so that when mated form a substantially cylindrical surface. The interengaging surfaces C<SP>1</SP>, D<SP>1</SP> mate in an axial plane of the connector. Rectangular ribs and grooves formed on one surface mate with corresponding grooves and ribs on the other surface. A shackle E on the part C is pivotally connected to its chain whilst the part D has a bore D<SP>5</SP> to receive its cable which is then secured by a pin locatable in a hole D<SP>6</SP>. A surrounding sleeve F for the connector A<SP>1</SP> is provided with an internal thread H to engage a thread G, Fig. 2. A modified sleeve J for the connector B<SP>1</SP> is slidably mounted on the part D and is urged to its operative position by a spring K. Alternatively the sleeve may be held in place by a spring ball catch or by a pin passing through it and one of the mating parts. The spacing of the ribs and grooves is different for the two connectors so that the part D of one connector cannot be mated with the part C of the other connector and thus interchanging of the control cables is prevented. Other forms of projections and recesses may be provided on the mating parts in lieu of those shown. The connector parts may be swaged to the cables and chains.
