Abstract: 250,403. Berkel, C. F. M. van, and Thomas, H. May 2, 1925. Addition to 225,342. Cutting slices in succession. - In a slicing- machine wherein the meat table is guided by a narrow guideway comprising two members, one of which is fixed and the other is movable relatively thereto, and a third member or guide disposed between the fixed and movable members, as claimed in the parent Specification, the movable member is arranged automatically to move laterally to tighten the guide during the feed movement and to loosen the guide during retraction. Means are also provided to loosen the guide positively for manipulation or removal of the meat table, the said means also lifting the feed-nut from the feed-screw. The meat table 1 is guided on the undercarriage 2 by a narrow guide comprising a flanged plate 5 secured to the meat table and engaging a groove 7 in the carriage 2, and a laterally movable member 10, slidable on bolts 12 and having a flange 11 adapted to engage a guide flange 9 on the carriage 2. The member 10 is provided with oblique recesses 15, 16 which are engaged by blocks 17, 18 carried by pins 19, 20 secured to the underside of a longitudinally movable slide member 21 guided between the plate 5 and a strip 22 which is engaged by adjusting-screws 23. The slide 21 is pressed continually in one direction by a spring 24. The positive release of the guideway is effected by a bar 27 which is mounted at one end on a crank arm 29 pivoted to the table 1 and at the other end is hook-shaped to engage a cam 44 which is rotated, to move the bar longitudinally, by a handle 37. The bar 27 is connected to the slide 21 by a pin 34. The handle 37 is associated with a register plate 41 which is shaped to retain the handle in one of these positions by a displaceable spring stop 43, the position A, Fig. 1, being the normal operative position, B being the position in which the guide is loosened and the feed nut 45 raised for adjustment of the meat table, and C being the position in which the member 10 is sufficiently displaced to permit removal of the meat table. The bar 27 is raised at one end by the crank 29 and is connected by a pin 50 and slot 51 to the feed nut carrier 46, which is pressed downwardly by a spring 49 and is slidable on guides 47<a>, 47<b>. The crank 29 has an eccentric pivot connection with the table 1 to permit adjustments consequent on the wearing of the feed nut. In operation, the frictional drag of the slide 21 between the plate 5 and the strip 22 tightens the guide during the feed, and vice-versa, in virtue of the oblique slots 15, 16 and co-operating blocks 17, 18.

Title: Polymeric phosphonitrilic derivatives
Inventor: COATES HAROLD
IPC: C08G79/025
Filed: 1962-03-27
Abstract: The invention comprises cyclic polymeric phosphonitrilic compounds of the general formula PnNnClx(OR)y wherein R is a fluoroaryl or fluoroalkaryl radical, n is an integer of at least 3 and x and y are integers (x may be zero) such that x + y = 2n, and mixtures of such polymers having different values of n. n is preferably 3 or 4 but may be up to 17.  They may be obtained by reacting a cyclic phosphonitrilic chloride polymer (PNCl2)n where n is an integer of at least 3 with a fluoroaryl- or fluoroalkaryl-hydroxy compound, preferably in the presence of an acid acceptor, e.g. a tertiary base such as triethylamine, or with an alkali metal salt of the fluoraryl- or fluoroalkaryl-hydroxy compound. The reaction is preferably carried out in a solvent especially a polar solvent e.g. acetone, tetrahydrofuran, diglyme or chloroform or a mixture of a polar solvent with a hydrocarbon e.g. toluene. The reaction is preferably effected by mixing the reactants at below 20 DEG  C. and then heating to reflux temperature, e.g. about 180 DEG  C., usually for from 2 to 24 hours.  The preferred fluoroaryl- or fluoro-alkaryl-hydroxy compound is a phenol or naphthol in which all the hydrogen atoms have been replaced by fluorine atoms or, at least 4 hydrogen atoms in the case of phenol and at least 6 in the case of naphthol have been replaced by fluorine atoms and the remaining hydrogen atom is replaced by an alkyl or perfluoroalkyl group such as methyl or perfluoromethyl. Examples are given for the production of P3N3(OC6F5)6 and P4N4(OC6F5)8.  The products are useful as high temperature fluids, e.g. as hydraulic fluids, transformer oils or heat transfer media and when they contain one or more chlorine atoms they can be cross linked with a fluorodiol, e.g. perfluorohydroquinone to give a resin.
