Abstract: 1524767 Secure data transmission INTERNATIONAL BUSINESS MACHINES CORP 25 March 1977 [26 April 1976] 12736/77 Heading H4P For secure transmission, in cycles of operation wherein a plurality of "n" blocks, each block comprising "b" bits are enciphered or deciphered in each cycle, a first block X, of clear bits is enciphered in dependence upon a set K of cipher bits, each succeeding block, e.g., the i th being similarly enciphered with cipher bits derived according to the modulo-2 addition algorithm K i =K i-1 (+) X i-1  (+) Y i-1 , the blocks X i being clear data, Y, the enciphered data. The encipherment, taking the form Y i =f(K i , X i ), of each block thus depends on the preceding ciphering operations in the cycle. The same cipher bit algorithm is used for deciphering, the inverse operation X i  =f(K i , Y i ) being used for deciphering, see Figs. 4, 5. Since both the enciphering and deciphering, at each stage of the cycle are dependent upon the preceding operations in the cycle, a message of B+nb bits can be authenticated by means of authentication bytes at the beginning and ending of the message as a whole, see Fig. 3 (not shown). This is compared with disadvantageous block ciphering, Fig. 2 (not shown) wherein authentication is required at the beginning and ending of each block. Enciphering /deciphering apparatus is disclosed in relation to Figs. 6A, 6B (not shown).

Title: Process for the manufacture of unsaturated optionally haloge nated hydrocarbon polymers with reactive silyl sidegroups
IPC: C08L101/10
Filed: 1974-03-22
Abstract: 1461531 Poly(silylalkenamer) preparation CHEMISCHE WERKE HULS AG 22 March 1974 [23 March 1973] 12776/74 Heading C3P A polymer containing silylalkenamer groups is obtained by subjecting to ring-opening, with a catalyst containing a niobium, tantalum, molybdenum, tungsten and/or rhenium compound, a polymerizable material comprising a hydrolysable silyl substituted, optionally halogenated, cyclic olefin or a mixture thereof with another optionally halogenated cyclic olefin and/or with an optionally halogenated hydrocarbon polymer containing double bonds. In an alternative procedure the monomeric silylsubstituted material is replaced by the corresponding polymeric silylalkenamer, obtained in a previous batch. Where polymeric starting materials are employed, they undergo an analogous rupture at the double bonds with interchange of the resulting alkenylidene groups with the polymer being formed, to produce analogous silyl alkenamer/other alkenamer copolymeric materials. Where the polymeric silyl alkenamer alone is treated with the catalyst the resulting rearrangement of the mers leads to molecular weight regulation. Where appropriate, the electron-donor functions of the hydrolysable groups on the silyl group may be compensated by addition of a Lewis acid, typically constituted by an aluminium alkyl or halide such as is employed as cocatalyst with the transition metal compounds. In the examples, 5-methyldichlorosilylnorbornene is homopolymerized or 5-trichlorosilyl norbornene is copolymerized with cyclopentene, cyclopentene and cis,cis-cyclooctadiene-1,5 or cycloctane are copolymerized with 5-(trichlorosilylethyl) norbornene, 5-trimethoxysilylnorbornene or 3-(diethoxymethylsilyl)propyl - cyclooctene - 1 and cyclopentene are copolymerized and 5-(trichlorosilyl ethyl) norbornene or 1-trichlorosilyl cyclododecadiene-4,8 are reacted in the presence of cis - 1,4 - polybutadiene, the catalysts being WCl 6 -AlEtCl 2 -EtOH together with regulators such as octene-1, vinyl acetate, and 1,10 - bis(methyl - dichlorosilyl) - decene - (4). The silylpolyalkenamers may be hydrolysed and cross-linked via the silanol groups formed, or cross-linked via the double bonds using the usual sulphur and peroxy curing.

Abstract: 1384478 Splicing record tapes HAMA HAMAPHOT KG HANKE & THOMAS 16 March 1973 12811/73 Heading G5R [Also in Division G2]  Apparatus for splicing strips includes parts for aligning the strip ends with slight overlap, for cutting the overlapped ends to produce an accurate abutment of the strips and for applying an adhesive splicing tab which is wrapped to form a U-shape around the abutted ends. As shown cine films or tapes 1, 2 are aligned by pins 42, 43 and cut by an edge 26 which is drawn across the overlapped ends of strips 1, 2 by pulling on handle 25<SP>1</SP>. The edge 26 and handle 251 are on a carriage 21 which can remain in the Fig. 3 position, after cutting, because detent bar 27 engages depression 29 (see Fig. 5, which shows a subsequent position) and thus acts against tension spring 24<SP>1</SP>. Closing lid 33 permits pins 36, 37 to enter holes 31, 32 to depress detent bar 27 and, on raising the lid 33, the carriage 21 moves to the Fig. 5 position where the detent bar 27 engages shoulder 39. The adhesive splicing tab 3 is held by its backing strips 7, 8 above teeth 54 of applicator 45. The applicator 45 is pivoted about its hinge 48 (see Fig. 5) to strip off the tab 3 from its strips 7, 8 and apply a half of its surface to the upper faces of the strips 1, 2. The teeth 54 are retracted during this application by compression, during the application, of the resilient block 52. Simultaneously pins 65, 66 on the applicator 45 enter holes 31, 32 and release the detent bar 27 so that, when the applicator returns to the Fig. 3 position, the carriage 21 moves towards hinge 34 and roll 68 wraps the other half of the tab 3 on to the lower faces of the strips 1, 2. This wrapping is aided by the partial adhering of the other half of the tab 3 to the edge of platform 63 of the carriage 21. Thus the carriage 21 pivots the other half about the first half of the tab and places it clearly in the path of roll 68.
