Title: Improved printing block for printing in colours
IPC: B41M1/14
Filed: 1937-02-17
Abstract: 495,863. Platen machines ; inking- apparatus. GRUN, C. Feb. 17, 1937, No. 4783. Void. Convention date, Feb. 18, 1936. [Class 100 (ii)] Platen machines; inking - apparatus.-A block 1, for printing in different colours is combined " with a ribbon or like element 2 comprising apertures in such conditions that the ribbon covers the characters during the whole duration of the normal printing and uncovers the latter at the moment of printing in predetermined different colours, the ribbon constituting for this purpose an inking ribbon and coming normally into contact with an inking-roller 5." The inking-roller is preferably geared to a ratchet-wheel 9 cooperating with a detent 7 and pawl 8 on a spring-actuated lever 6 which " during its shifting movement in the printing-machine is met by the inking-rollers and thus becomes depressed." The block and guides 3, 4 for the ribbon may be supported by " elastic elements." The lever 6 may be replaced by a pair of " levers " for driving alternately two mutilated pinions which drive the inking- roller 5 in the same direction. To prevent the levers from printing lines or dots on the paper, they may be coated with ink-repelling material, or they may be actuated by auxiliary levers.

The conveyer moves through a distance equal to the length of the centre ram block 17, or to a fraction of it. In the latter case the ram assembly or part of it may be rockable to distribute the pressure over several adjacent portions of material progressively reduced in thickness by the successive pressings. The portion of the conveyer below the ram block 17 is supported by a fixed grid structure 46 below which is a liquid-collecting pan 48 from which extends a duct 49. To the left of the ram the conveyer is scraped by a scraper 53. The lower surface of each of the ram blocks 17, 18 is covered by an endless band 19 of rubber or the like which is driven in the direction of the arrow 21, when the ram assembly has been lifted clear of the conveyer 25, by engagement of a free-wheel chain sprocket 41 on the driving roller 20 with a length of roller chain 43 secured to the framework. Preliminary drainagepans 54, 55 may be provided. In Fig. 3 (not shown) a preliminary pressing ram of simpler construction is suspended from a lever articulated at one end to the ram assembly and hinged at the other end to upward extensions of the right-hand uprights 3. A single band 19 may be provided which passes around both the main and preliminary rams.

[Class 112.] In a machine with differential feed dogs, the feed rocker has a projecting boss which operates the main and auxiliary feed bars. The invention is shown as applied to an overseaming machine. The feed rocker 5 is fixed on the rock shaft 4 and has two lateral spaced arms 6 and 7, each arm having an aperture to receive a pivot pin 8. The rocker 5 is rocked by the main shaft 2 through an arm 12 pitman 9 and eccentric 10. The pivot pin 8 carries the enlarged apertured end 14 of the auxiliary feed bar 15 which carries the auxiliary feed dog 17. The main feed bar 18 is slidably carried on the auxiliary feedbar and is provided with a rib 19 which enters a channel 20 in the auxiliary bar, and a longitudinal aperture 21 which receives a stud 22 carried by the auxiliary bar. This connection permits the main feed bar to be reciprocated independently of the auxiliary bar. The main feed bar carries the main dog 23, in rear of and in alignment with, the auxiliary dog. The auxiliary bar 15 overhangs the usual feed lift eccentric on the main shaft and a short pitman 25 embracing this eccentric is pivoted to the bar 15 by the stud 26. This connection gives both bars their rising and falling movement. To vary the throw of the main dog relatively to the auxiliary dog, the main feed bar is connected to an adjustable sliding member 27 by a link 28. A boss 31 can be adjustably secured in any position in a slot 29 in the member 27.

Abstract: 555,656. Cathode-ray tubes. STANDARD TELEPHONES & CABLES, Ltd. May 1, 1942, No. 5890. Convention date, Feb. 14, 1941. [Classes 39 (i) and 40 (iii)] In facsimile printing apparatus using a cathode ray tube 10 a flat beam from a cathode 11 after passing through a diaphragm 12 and accelerator 14 is deflected electromagnetically or by plates 15 over a number of discontinuous loops 18 carried on a rod 23 of insulating material ; the inner sides of the loops are within the tube 10 but their outer ends 25 are outside and an electrosensitive tape 35 passes over one set of these ends 25, an electrode 37 bearing on the tape opposite the ends. The impact of the beam on the loops 18 causes secondary emission, which is collected either by an auxiliary electrode 19 or by a conductor 27 housed in a recess 28 in the rod 23. The auxiliary electrode may be a plate or as shown is a carbon coating on the tube ; it is connected through a biasing source 45 to a signal receiving circuit comprising a resistance 51, an amplifier 47 and a resistance 46. The variation of potential of the auxiliary electrode corresponding to the received signal results in variation of flow of the secondary emission ; with no signal current all the secondaries emitted are collected by the electrode 19 but when a signal is impressed on the impedance 51 and the potential of the auxiliary electrode is sufficiently low all primary electron flow is to the output circuit and a signal is received on the tape. This is moistened with a suitable electrolyte. The spaces between the loops on the rod 23 may carry fluorescent material to enable the working to be observed. The accelerator electrode 14 is at the same potential as the coating 19, which may be divided into two or more sections. In a modified system of working, flow to the electrode 37 may be arranged when no signal current is applied to the impedance 37, the flow stopping as a signal is received.
