Title: Improvements in inking apparatus for printing or like machines
IPC: B41F1/40
Filed: 1933-10-23
Abstract: 417,914. Printing-machines. PATIENT, J., Woodcote, Elm Park Road, Pinner Green, Middlesex. Oct. 23, 1933, No. 11063/34. Divided out of 417,897. [Class 100 (ii).] Inking - apparatus.-An improved inking- mechanism for printing and like machines employing a reciprocating type or die-carrying beam, particularly of the type described in Specification 417,897, comprises an inking roller mounted on a pivoted lever connected to the die or type beam to be oscillated thereby and adapted to move over the face of the type and over an arcuate ink-distributing member which is oscillated in fixed guides transversely of the path of the inking-roller. A die beam 90 reciprocates vertically over a counterpart 63 on which the sheet is placed against a fence 64. A lever 93 carrying two rollers 94, 95 is pivoted to the die beam and to a member 96 which is horizontally slidable in the frame. Reciprocation of the die beam 90 therefore oscillates the lever 93 and in consequence the roller 94 transfers ink from a fount roller 98 to an arcuate distributing member 99, whence it is carried by the roller 95 to the die or type. The distributing member, whose arc is preferably circular, is mounted on transverse guides and reciprocated by an eccentric pin 100. The pin 100 is carried by a shaft 101 which is rotated through pawl and ratchet mechanism by a spring-pressed slidable rod 106. The rod 106 is operated by a bell-crank lever 107 and link 91, connected to an arm 76<a>, which is operated by a cam on the main shaft 2 of the machine.

Title: Improvements relating to stapling artificial fibres
IPC: D01G1/10
Filed: 1939-04-12
Abstract: 528,045. Stapling filaments. HADDAN, R. (Phrix-Arbeitsgemeinschaft). April 12, 1939, No. 11101. [Class 120 (iii)] Artificial fibres in the form of a sliver or ribbon are passed through a cutter adapted to make oblique cuts across the ribbon at intervals corresponding to the staple length and then through a drawing frame wherein the rollers are so spaced that in the course of passing through the frame each of the cut sections is gripped simultaneously by at least two pairs of draft rollers. The effect is that the tips of cut filaments are subjected to a drawing action not extending to such filaments as are not yet nipped by the second pair of rollers so that the drawn filaments slide along the sides of those not drawn, breaking down adhesion. The cuts may be of V-shape and may be produced by rotating cylinders having a sharp-edged worm composed of a right and left hand part, as shown in Fig. 6. In the machine shown in Fig. 8, slivers from several spools 2 are passed beneath a spring-loaded cutter cylinder 9, shown in detail in Fig. 5, and the obliquely-cut strips are then led through a drawing frame containing pairs of rollers 13, 14, 15 spaced apart so as to produce the drawing effect referred to above. Specifications 434,250 and 514,564 are referred to.

[Also in Division A5] The invention comprises tetracycline antibiotics which carry as a substituent at the 2- amide nitrogen atom, a cycloheptatrienyl group which may be substituted by tertiary alkyl of C 4 -C 10  carbon atoms, carboxyl, halogen or aromatic acylamino, which may be substituted by nitro or halogen. The tetracycline antibiotic may be tetracycline, 5-oxytetracycline, 7- chlorotetracycline, 7 - bromotetracycline, 5- oxy - 7 - chlorotetracycline, 6 - deoxy - 5 - oxytetracycline, 6 - deoxytetracycline, 6 - deoxy-6- demethyltetracycline, 6 - demethyltetracycline, 6 - demethyl - 7 chlorotetracycline, 6 - methylene tetracycline, 6 - methylene - 5 - oxytetracycline, 7 - dimethylamino - 6 - demethyl-6- deoxy tetracycline, 5 - oxy - 6 - demethyltetracycline or a 4-epi or anhydro compound thereof. Aminomethylation products of tetracyclines in which the 2-carbonamide group is set free under the reaction conditions may also be used as starting materials. Salts may be formed with inorganic and organic acids and also with bases. Typical compounds are N- cycloheplatrienyl tetracycline and N-(carboxycycloheptatrienyl) - 5 - oxytetracycline. The compounds are prepared by reacting in a solvent a tetracycline antibiotic or a salt thereof, with a tropilium (cycloheptatriene) salt which may be substituted as hereinbefore mentioned, and, if desired, converting the N-cycloheptatrienyl tetracycline into a physiologically tolerable salt. The reaction is preferably carried out at a pH higher than 3 especially higher than 6À5 at temperatures of 20 to 50 C. The compounds are antibacterials active against tetracycline resistant microorganisms and are used in pharmaceutical compositions (see Division A5).

Abstract: 430,116. Motors for reciprocating conveyers. FINLAY, R. P., Lincombe, Llanwern, near Newport, and FINLAY CONVEYOR CO., Ltd., Transporter Bridge, Newport, Monmouthshire. April 13, 1934, No. 11124. [Classes 122 (ii) and 122 (iii)] A double - acting, fluid - pressure motor for operating reciprocating- conveyers is convertible into a singleacting motor by closure of a valve 23 controlling the supply of pressure fluid to one end of the cylinder, and by the removal of a cover plate 24 therein. The fluid distribution is controlled by a piston valve arranged rearwardly of the piston with its axis offset from and parallel to the piston rod. The valve is moved rearwardly by compression in the main cylinder, and forwardly by fluidpressure supplied from the cylinder to the rear of the valve when the piston passes one or more ports 10, 11, 12 put into communication with an auxiliary passage 14. Fluid passes to the ends of the main cylinder by passages 4, 6, 8, 9 and 4, 17, 18, 19 respectively, and exhaust through passages 19 and 21 respectively, around the valve, to the outlet 16. The sudden admission of fluid to the left of the piston effects the displacement of the coal. Specifications 171,297, 328,883, [both in Class 122 (ii)], and 393,696 are referred to.

Material to be spin-dried passes from a hopper 7 into a member 8 which rotates at high speed to centrifugally project it into a first centrifugal drying compartment 9 of inverted frusto-conical form, the liquid being upwardly projected through a sieve 10 into a circular collecting chamber 11 while the material is fed by conveyer worms 13, 14 over a sill 15 to be projected centrifugally into a second inverted frusto-conical drying compartment 16 cooperating with a sieve 17. The compartment 16 is of larger diameter than compartment 9 and has a conveyer worm 18 to ensure downward progression of the solid material under a sill 19 to a third drying compartment 26 co-operating with a sieve 27 and conveyer worms 28. The compartment is of larger diameter again and the dried material is projected from the sill to a collecting tank 30 in which a yielding deflector 31 is mounted to prevent disintegration of the material particles. During passage through the second compartment, the material may be washed or chemically treated by any suitable liquid entering at 20 into the drier and passing through an annulus 22 and passages 23, 24 for countercurrent flow up the compartment 16 with respect to the material. A neutral or other gas atmosphere may be maintained in the spindrier by the provision of a fluid-tight joint between the fixed casing and rotary parts of the machine.

Each duct 14, 15 has three parallel passages similar to 14a, 14b, 14c, shown, and at intervals sets of dampers similar to 25, 26, 27, are provided, being disposed preferably just prior to a heating means 20 in the direction of gaseous flow. The dampers are relatively staggered and are supported on spindles similar to 28, 29, 30 each of which is journalled at one end in the passage wall associated with its damper and at the other end passes from the ducting through spacing bushes 31, 32, 33, to the outer wall of the oven. The protruding ends of the spindles are provided with handles 28a, 29a, 30a, comprising spring-loaded studs 28b, 29b, 30b which engage recesses in the oven wall marked to indicate the angular position of the damper within the passage. The facial area of each damper is substantially equal to the crosssectional area of the passage in which it is disposed and to prevent complete closure of the passage the damper is prevented from taking up a vertical position by a stop on the oven wall coacting with the adjusting handle.
