Title: Stabilized cellulose esters
IPC: C08L1/12
Filed: 1964-02-21
Abstract: Neopentyl phosphites having the formula <FORM:0996254/C2/1> where R is an alkyl, phenyl or alkylphenyl radical, e.g. phenyl, decyl, p-tert-butylphenyl, and p-methylphenyl neopentyl phosphites, are obtained by an ester exchange reaction, e.g. using triphenyl phosphite or trialkylphenyl phosphite and neopentyl glycol as starting materials.  The preparation of p-methylphenyl neopentyl phosphite from neopentyl glycol and tricresyl phosphite in the presence of finely-divided sodium is described.  The neopentyl phosphites are used for stabilization of cellulose esters (see Division C3).ALSO:A cellulose ester composition comprises a cellulose ester of a fatty acid containing 2 to 4 carbon atoms, and a neopentyl phosphite of <FORM:0996254/C3/1> where R is an alkyl, phenyl or alkyl phenyl radical.  The cellulose ester is thereby stabilized against colour and molecular weight deterioration. Specified phosphites, which are made by ester-exchange reactions (see Division C2) are p-methyl phenyl, p-tert-butyl phenyl, decyl, and phenyl neopentyl phosphites.  The composition, which may contain plasticizers and other stabilizers, preferably contains at least 0.01 parts of neopentyl phosphite e.g. 0.01-0.5 parts, per 100 parts of cellulose esters. Specified compositions contain (1) cellulose acetate butyrate, dibutyl sebacate, strontium, naphthenate, epoxidized soy-bean oil, phenyl neopentyl phosphite and decyl neopentyl phosphite; (2) cellulose acetate propionate, dibutyl sebacate, strontium naphthenate, epoxidized soy-bean oil, and phenyl neopentyl phosphite.

Title: Improvements in or relating to the transmission system in movements for measuring instruments
IPC: F16H55/00
Filed: 1944-04-22
Abstract: 583,901. Movements for measuring instruments. WEINGART, R. I. N. April 22, 1944, No. 7509. Convention date, April 24, 1943. [Classes 106 (ii) and 106 (iv)] In movements for measuring instruments wherein a temperature or pressure responsive element 10 operates a sector 18 which drives a helical member 28 on the pointer shaft 26, as described in Specifications 557,617 and 557,639, friction is reduced by supporting the member 28 against axial thrust by a non-driving supporting sector 35 moving with the sector 18 and having rolling contact with a cone 39 secured to the shaft 26. The taper of thrust surface 39 should be sufficient to provide point contact with the edge 36 of sector 35. Calibration may be effected by bending the edge 35 as shown at 40, or by varying the radius of the sector 35 to cause axial displacement of the helix 28 as it rotates. Preferably, however, both driving edges 21, 36 will lie on the same cylindrical surface. The sector 35 may be fitted with a non-metallic driving edge to reduce wear. The sectors 18, 35 may be formed from a single piece of metal. Fig. 5 shows a supporting sector 62 contacting two thrust -faces 61 to restrain axial movement of the driven spindle in either direction.

Title: Printing mechanisms
IPC: B41F17/02
Filed: 1967-02-20
Abstract: 1,143,063. Printing labels; cutting continuous strips delivering. W. KRAUT, [trading as BIZERBA-WERKE WILHELM KRAUT K.G.]. 20 Feb., 1967 [25 Feb., 1966], No. 7913/67. Headings B6C and B6H. A mechanism for printing either on a continuous strip or on individual labels carried by a support strip comprises a printing block and/or type wheels, feed means for drawing a continuous strip from a magazine cell, and delivering it, after printing, to a cutter which separates portions of the continuous strip, and a readily removable draw-off device which operates to feed a support strip past the printing means and past means for stripping individual labels therefrom. The mechanism also includes means for changing from continuous strip to label printing which disengages the feed means for the continuous strip and immobilizes the cutter. A particular application is the printing of prices and weights on labels for commodities. Printing on continuous strip (Fig. 3).-Continuous paper strip 60 is drawn off from magazine reel 59; variable details, e.g. prices and weights, are printed on the strip by means of a printing hammer 57 co-operating with a printing block 56 and type wheels 55 through ink ribbon 74. The strip is also printed with non-varying details e.g. the name of the supplier, by means of a further printing block 21 which is inked by inking roller 24. The strip is fed by feed roller 20, the feed roller 20 and printing block 21 cooperating with counter-pressure rollers 28 and 29 which are carried on angle arms 26, 27 connected by a toggle linkage 33, 34 and displaceable pivot pin 34. The drive mechanism comprises two Maltese crosses (10), (11) (Figs. 1 and 2, not shown), rotatable independently of each other on a common shaft 12, and driven by a drive arm (9) carrying two pins (7), (8), the shorter pin being engageable only in the Maltese cross (10) which drives the printing block 21, the longer pin engaging both Maltese crosses to drive both the block 21 and the feed roller 20. Cutting and delivering.-After printing, the continuous strip 60 is severed by a cutter 47, and the thus-produced labels drop into delivery tray 70. Printing on labels (Fig. 3).-A magazine for support strip 64 carrying self-adhesive labels replaces magazine 59. These labels already have some matter pre-printed, so feed roller 20 and block 21 are rendered immobile by displacing the drive pins (7), (8) out of engagement with Maltese crosses (10), (11) by means of a change-over lever (38). Type wheels 55 and/ or printing block 56 provide the variable details on the labels; and support strip 64 is drawn off by means of the detachable draw-off device 61, in particular by means of feed rollers 66, 67. The self-adhesive labels 100 are peeled-off by deflector pins 65, and the tray 70 may contain a heating device in the ease of labels having heat-sensitive coatings for application to commodities.
