Title: Improvements in or relating to printing presses
IPC: B65H3/08
Filed: 1946-03-25
Abstract: 609,891. Printing-machines. HOLMES, A. H., HOLMES. F.. and HOLMES. A. L March 25, 1946, No. 9051. [Class 100(i)] In a printing-machine of the kind in which sheets are fed to the impression cylinder by an oscillating suction bar and a transfer table, means are provided to enable the suction bar to feed a sheet at alternate operations of the press only, so as to permit of double inking of the forme. A flexible pipe 4 connected to the suction bar is connected to a pipe 3 leading to a vacuum pump by means of a box 2 and a valve plunger 10 which is pressed by a spring 12 towards open position. The valve can open only when permitted by the low part of a cam 14, but a star wheel 19 is rotated a quarter revolution by a pin 21 on the cam, and the arms 19, 20 which are long and short respectively are brought alternately into the path of the pin 23 on a lever 22 connected to the plunger 10. The arms 19 prevent the plunger 10 from moving to open position and so sheets are forwarded only on each alternate operation of the machine. When single inking is required the pin 21 is constructed so that it can be held in such a position that it does not rotate the star wheel 19, and the wheel 19 is set so that the valve opens at each rotation of the cam 14.

Title: Improvements in and relating to cellulose esters of dicarboxylic acid and composition containing these esters
IPC: C08B3/12
Filed: 1933-09-11
Abstract: Cellulose esters of dicarboxylic acids are made by directly reacting upon cellulose or an esterifiable cellulose derivative such as a cellulose acetate or acetate-propionate with a non-resinous acid dicarboxylic acid ester of a monohydroxy compound or of a non-saccharide polyhydroxy compound.  The acid esters employed may be derived from aliphatic, aromatic, saturated, unsaturated or substituted dicarboxylic acids on the one hand, and from mono-, di- or tri-hydroxy compounds on the other; they may be ethyl hydrogen adipate, the corresponding esters of succinic and maleic acids in particular methyl and benzyl acid succinate, and ethylene glycol acid diphthalate.  The esterification may be assisted by an impeller such as chlor- or alkoxy fatty acid anhydride, by heating say to 100--125 DEG  C., and by the presence of a catalyst such as magnesium perchlorate.  The reaction mixture containing a solvent may be spread out in the form of a film, and then brought to reaction subsequently. Similarly moulded articles may be obtained directly by mixing together the cellulose derivative, the acid ester and a plasticizer, and moulding under heat and pressure, the reaction taking place during the moulding operation.  Specification 429,915 is referred to. The Specification as open to inspection under Sect. 91 refers to the preparation of non-resinous dicarboxylic acid esters of a non-saccharide polyhydroxy compound by directly reacting on a polyhydroxy compound such as ethylene glycol with an acid monobasic alcohol ester of a dicarboxylic acid, for example, ethyl acid phthalate, the reaction being carried out at a temperature not sufficiently high to cause resin formation.  This subject-matter does not appear in the Specification as accepted.

Abstract: 678,703. Converting. BRISTOL'S INSTRUMENT CO., Ltd. (Bristol Co.). April 26, 1951, No. 9750/51. Class 38 (ii). In an inverting system wherein a reed bearing a contact 18 and excited by an A.C. winding 16 vibrates between the poles of a permanent magnet 11, so that contact 18 alternately engages fixed contacts 21, 22 to which the D,C. input is connected, these fixed contacts are connected respectively through resistances 30, 31 to one end 35 of the primary winding of output transformer 33, the other end 34 of this winding being connected to the vibrating reed. Such a system produces A.C. potentials of proportional magnitude and of phase position dependent on the input D.C. and is suitable for measuring and similar circuits. The output current flows alternately through resistances 30, 31 which may be made with equal impedances much more easily than can the halves of the output transformer in the more usual inverter circuit, so that any alternating component of synchronous frequency in the D.C. input is eliminated from the output. Also any contact potentials resulting from contact 18 being of different material from contacts 21, 22 produce a component of doubled frequency in the output, which is not objectionable.
