Title: High speed printing mechanism
IPC: B41J9/32
Filed: 1963-08-22
Abstract: 968,185. Selective printers. NATIONAL CASH REGISTER CO. Aug. 22, 1963 [Sept. 14, 1962], No. 33205/63. Heading B6F. A high-speed printer comprises a plurality of continuously rotatable type wheels 11, Fig. 1, a corresponding plurality of hammers 25. associated with interposers 40 adjacent the hammers and lying out of a path of a plurality of hammer drives 20, mounted on hammer drive assemblies rotating in synchronism with the type wheels and a selectively operable electromagnet 36 rendered effective to cause the interposers 40 to be positioned in the path of the next available hammer drivers 20 to be struck thereby to actuate the associated printing hammers 25. In operation when a character to be printed has been selected the electromagnet 36, having a number of coils, has a dropout coil (not shown) energized to counteract the magnetic force of a holding coil so that the magnetic field will decay and allow a spring 43 to move the armature 37 counter-clockwise against a stop-bar 35 and bring the interposer 40 into the path of a selected hammer driver 20. The driver 20, which is pivotally mounted between a pair of discs 18 mounted on a shaft 17, rotating synchronously with the type wheels, rests on a stop surface 24a of a radial lobe 21 and engages the lower interposer 40, Fig. 4. The energy from the driver 20 is then transferred to the printing manner 25 through the interposer carrier 30 to drive the hammer into impression position (Fig. 5, not shown). The impact of the hammer can be adjusted by an eccentrically mounted impact control stop-bar 49. As the hammer driver 20 proceeds in its circular path about the shaft 17, it is pivoted clockwise about its pin 23 until it comes to rest against a second stop surface 24b in which position it has moved the interposer 40, upwardly (Fig. 6, not shown), causing the armature 37 to be lifted against a stop-bar 47 so that the re-established magnetic field of the magnet 36 may restrain the armature 37. Simultaneously the hammer is restored under the action of spring 27, which also moves indirectly the interposer carrier 30 against the stop surface of the bar 35. As the hammer driver 20 leaves the bifurcated end of the hammer 25, the driver 20 is restored under the action of centrifugal force to the original position in which it rests against the stop surface 24a.

Title: Materials with complexing functions
Inventor: JONES JOHN IDRIS
IPC: C08B31/08
Filed: 1958-10-20
Abstract: Materials having a complexing function are made by reacting an organic compound containing one or more chelating groups and which is capable of forming complexes with metal ions and which contains a reactive halogen atom, with a polyhydroxy compound so that the organic compound is bound to the polyhydroxy compound through an ether (oxygen) linkage. The reaction may be so effected that only a limited number of the hydroxy groups of the polyhydroxy compound are converted into ether linkages.  A metal derivative of the polyhydroxy compound, especially an alkali metal derivative, may be used in the reaction. Specified polyhydroxy compounds include cellulose, polyvinyl alcohol, sugars, and starch. Compounds described include those of the structural formulae:- <FORM:0934571/IV(a)/1> <FORM:0934571/IV(a)/2> <FORM:0934571/IV(a)/3> <FORM:0934571/IV(a)/4> <FORM:0934571/IV(a)/5> <FORM:0934571/IV(a)/6> <FORM:0934571/IV(a)/7> <FORM:0934571/IV(a)/8> Compounds so made may be water-soluble or water-insoluble.  They may be used for the extraction, concentration, and purification of metal ions from solution under either static or dynamic conditions, e.g. for the removal of harmful metal ions from the body; for the adjustment of metal ion concentrations in the body; for the control of biological systems by controlling the concentration of or removal of trace metals; and, in the form of their metal complexes, as agents toxic towards micro-organisms.

Title: Improvements in automatic weighing mechanisms particularly for filling and closing machines
IPC: B65B1/32
Filed: 1932-11-26
Abstract: 397,348. Weighing- apparatus. HESSER MASCHINENFABRIK AKT.- GES., F., 99, Olgastrasse, Cannstatt, Stuttgart, Germany. Nov. 26, 1932, No. 33500. Convention date, Dec. 12, 1931. [Class 143.] An automatic weighing- mechanism, more particularly for filling and closing machines is provided, above the load pan of the weighing apparatus and separately from the conveyer mechanism, with a support arranged in the level of the feeding track of the packages, and the support is adapted to be operatively lowered and raised to place the package to be weighed from the feeding track freely upon the balance and to raise again the package off the balance up to the level of the feed track after the weighing process has been finished. The package p, Fig. 1, partially filled, is conveyed in known manner to a grid-like support 2 moved downwardly by an eccentric 15 so as to deposit the package on a scale pan 61 counterbalanced by a weights pan 62, Fig. 6. A second eccentric operating through a rod 20 rotates a vertical shaft 23, connected to a pair of pivoted feed gates 43 by means of a helical torsion spring and by a loose-motion pin-and-slot arrangement. The feed gates are thus opened and the material enters the package. A pawl 45 engaging the armature of an electromagnet 51 retains the feed gates in the open position. During the descent of the grid-like support 2 to deposit the package on the scale pan, an arm 71 actuated by the support raises a locking device 67, Fig. 6, to release the scale beam 60<1>. When the package has attained its correct weight, the weights pan 62 rises and a trip 101 liberates a spring-pressed arm 87 to close the circuit of the electromagnet 51 which then releases the pawl 45 and permits the feed gates to close under the action of the torsion spring. The grid-like support 2 rises again to lift the filled package off the scale pan, and the package is carried away for sealing and labelling. The rise of the support 2 again engages the locking device 67 with the scale beam, and an arm 80 on the locking device pushes back an arm 83 to reset the arm 87 and open the circuit of the electromagnet 51. If no empty packet reaches the filling station a catch, normally depressed by the presence of a packet, prevents the rotation of the shaft 23 and the feed gates remain closed.

Title: Improvements in the permanent deformation of live human hair and other keratinous fibres
Filed: 1958-10-21
Abstract: In a process for the permanent deformation of live human hair and other keratinous fibres, the hair or fibres are impregnated with a freshly prepared aqueous solution obtained by adding, to an aqueous stock solution having a pH of 8-9,5 of a N- mono substituted or N- unsubstituted mercapto alkanoic acid amide, an acid or acidic buffer composition in a quantity sufficient to ensure a pH of 5-7,5 in the resulting solution; the hair or fibres are then constrained in a desired configuration and fixed in known manner while held in such a configuration.  Mercapto alkanoic acid amides preferably used are those having the general formula:  <FORM:0859347/IV (c)/1> in which R and R1 are hydrogen atoms or alkyl groups containing not more than 4 carbon atoms and R11 is a hydrogen atom or an alkyl or hydroxy alkyl group containing not more than 4 carbon atoms.  The concentration of amide in the amide solution is preferably 0,5-1,5 molar and the alkalinity may be adjusted to a pH of 8-9,5 by the addition of weak bases, e.g. ammonia or organic bases such as mono-, di- or triethanolamine. The acid or acidic buffer composition may contain weak acids, e.g. acetic, citric or lactic acid, or salts possessing marked buffering properties and giving acid solutions on hydrolysis, e.g. sodium, potassium or ammonium salts of phosphoric, citric or phthalic acid, which may be in the form of an aqueous solution or a powder.

Title: Improvements in or relating to the starting of impression cylinders of cylinder printing machines
IPC: B41F3/46
Filed: 1965-08-09
Abstract: 1,115,526. Stop-cylinder presses. ADAMOVSKE STROJIRNY NARODNI PODNIK. 9 Aug., 1965 [4 Sept., 1964], No. 33977/65. Heading B6C. The impression cylinder 1 of a stop-cylinder printing press is rotated during the printing stroke of the forme carriage through the engagement of a rack 4 reciprocable with the carriage and a gear-wheel 3 which is mounted on the cylinder shaft and drivingly engages a disc 2 fast to the cylinder through a latch 5 pivotally mounted on the cylinder by a pivot bolt 6. The actuation of the latch into its operative position depends upon the functioning of a lever arrangement which is mounted on the cylinder and includes an operating spring 14. The positive engagement of the latch 5 and the disc 2 by the spring 14 is ensured by the provision of a lever arrangement 19 and 15 actuated through the engagement of a follower 21 with a cam 22 fixedly mounted on the shaft of the cylinder. Both the spring 14 and the cam-operated lever arrangement 15, 19 acts on an arm part 10 of a bell-crank 10, 8 which is pivotally mounted on the cylinder at 9. The bell-crank part 8 is segment shaped and incorporates a groove for the reception of a roller 7 carried by the latch 5. Through the provision of a spring-loaded pivoted flap 11 in a slot of the arm part 10 the latter may not be moved by either the spring or the lever arrangement unless the flap 11 is clear of an obstruction 16 mounted on the cylinder. Such clearance is only possible if the sheet feed to the machine is correct. When this is so a pneumatic electrical or mechanical device operated by the delivery of a paper sheet deflects the flap 11 from the path of the obstruction, thus allowing the arm part 10 to function.
