Patent GB-399967-A (GB)
Title: Improvements in or relating to the manufacture of high ohmic resistances
IPC: H01B1/24
Filed: 1932-09-02
Abstract: In a process for manufacturing electrical resistances of high ohmic value by the deposition of carbon on an insulating carrier from a gaseous carbon compound, deposition of amorphous carbon at relatively low temperatures is prevented by employing such carbon compounds as have a high temperature of decomposition (i.e. above 600 DEG  C., but preferably between 800-900 DEG  C.), such as methane and others members of the homologous series.  The process may be hastened by admitting more readily dissociable compounds when the temperature has reached a sufficiently high value to prevent the formation of amorphous carbon.  Excess carbon deposited on the carrier is removed by admitting carbon dioxide at a temperature sufficiently low to prevent dissociation of the carbon monoxide formed.

Title: Electroscopic method and apparatus for testing the genuineness of woollen and silk materials
IPC: G01N33/36
Filed: 1922-09-14
Abstract: 198,320. Bernini, A. May 27, 1922, [Convention date]. Testing. - To test the genuineness of wool or silk, or the degree to which they are mixed with cotton or treated with other non-conducting dressing, an electroscope 1 is used. Gold leaves 3, earthed through the metal case 1 stand up as shown in Fig. 2 when the insulated plate 5 is charged by touching the head 7 with an ebonite rod rubbed with wool. The material to be tested is then brought into contact with the head 7 when, if it is pure wool or silk and therefore non-conducting, no discharge will take place and the leaves will remain upstanding. If the material is mixed with cotton or other conducting material the leaves will fall. The rate of fall gives some indication of the proportion of conducting to non-conduct. ing material, but a number of leaves preferably of different size and weight would give a better indication. The ebonite rod may be rubbed with the material to be treated and then applied to the electroscope to see if it will charge it. For carrying, the head 7 slides in flat against the case and the leaves lie flat on the partition 4. Another design has a fixed discharge head and gold leave? mounted on movable plates.

Abstract: 259,952. National Malleable & Steel Castings Co., (Assignees of Knorr-Brense Akt.-Ges.). Oct. 16, 1925, [Convention date]. Couplings, automatic.-In a railway vehicle provided with automatic rigid central butler couplers the air brake conduits s are connected by coupling members e, each of which is mounted upon a pipe member d guided in a sleeve b secured to a member a carried by the head of the vehicle coupler. Each coupling member e is provided with the usual sealing ring g and a pair of wing members f, while the pipe d is connected to a bayonet locking member n, which co-operates with the usued hose coupling member c., by a conical junction piece c which seats in a similar mouth piece. k on the pipe member d. The junction c is normally retained in the mouthpiece k by a spring h, which surrounds the pipe member and is interposed between the coupling e and sleeve b, and is prevented from rotating by a nose l thereon engaging a seat i formed in the said mouth piece k. In operation, during the coupling of the buffer couplers, adjacent coupling members e contact and disengage the junction pieces c and mouth pieces k against the action of the springs h, thus releasing the locking noses l and enabling the couplings e to rotate, after which the wings f on the members e interengage with one another. The internal diameter of the wings f is equal to the diameter of the couplings, e, so that when the couplings engage the wings embrace them to prevent any relative side movement.

Title: Improvements in platen presses
IPC: B41F1/54
Filed: 1924-10-21
Abstract: 223,915. Rockstroh, M. Oct. 22, 1923, [Convention date]. Platen machines. - In platen presses having automatic sheet feeding and delivery mechanism and a device associated with the platen-actuating mechanism to throw off the impression automatically when no sheet is fed, means are provided actuated by the impression throw-off device to interrupt also the ink supply and the inking of the forme. The platen 1 is reciprocated along guides 2 by a crank 4 and rods 3 in the ends of which are engaged eccentrics 14 on a shaft 13 on which the platen is mounted. Sheets are taken from a feed table 49 and conveyed through and delivered from the machine by grippers 10, 11, 12 on two rings 9 revolving round the platen. Tripping-arrangements. - Tripping of the impression is effected automatically by rotation of the shaft 13 if no sheet is fed to the front stops 50 in the following manner. An arm 15 on the shaft 13 is connected by a rod 16 to a bell crank lever 17 pivoted at 18 to the platen 1, the other arm 19 of the bell crank being connected by a rod 20 to a cross-head 21 which normally is prevented from sliding along a guide 22 bv a pawl 23. If no sheet is fed to the front stops 50, a finger device of known construction disengages the pawl 23, and the cross-head 21 moves to the right, thereby actuating the bell crank 17, rod 16, and arm 15 so as to turn the shaft 13 and throw off the impression. Inking-apparatus.-Ink supplied from a fountain 26 is transferred by a messenger roller 25 to a cylinder 24 and thence applied to the forme by rollers 27 reciprocating along guide rails 28 having wedge-shaped blocks 29 engaging corresponding recesses in bars 30. A spindle 31 carries slotted levers 22 engaging studs 33 on the rails 28, and is adjustable by means of a lever arm 34, rod 35, spring 36, and nut 37 to move the rails 28 higher or lower in known manner. The spindle 31 also carries an arm 38 connected by a link 39 to a lever 41 pivoted at 40. When the cross-head 21 moves to the right and actuates the platen throw-off shaft 13, a roller 43 on the cross-head engages the lever 41 and depresses it, causing the guide rails 28 to move downwardly and outwardly by reason of the wedges 29, so that the inking rollers 27 on their next downward movement do not contact with the forme. At the same time the messenger roller 25 is prevented from contacting with the ink cylinder 24 by a pivoted lever 46 connected with the guide rails and engaging an arm 47 on the carrier 48 of the messenger roller. When the throw-off shaft 13 is actuated to restore the impression, an abutment 44 on the platen strikes the lever 41, thus raising the guide rails 28 and rendering the inking rollers operative.

Abstract: 994,223. Finishing fabrics. SUCCESSEURS DE GROSSELIN & DEHAITRE. July 2,1962 [July 21,1961], No. 25204/62. Heading D1S. A fabric pile cutting machine of the type in which fabric passes over a bed having associated therewith a rotatable cylinder fitted with cutting blades is characterized in that the input end of the machine is fitted with a back movement roll, over which the fabric passes continuously and which has driving means which can rotate it when desired in the direction of reverse motion of the fabric, and also with means adapted to hold the fabric under tension both in the forward and reverse directions of motion. Preferably the operating mechanism controlling the back movement of the roll is synchronized with an operating mechanism for disengagement of the cutting cylinder with respect to the bed. The coupling between the back movement roll and the driving mechanism preferably comprises a free wheel which is brought into engagement in the direction of reverse motion whereas in the forward direction the free wheel is automatically disengaged from the back movement roll which is then caused to rotate freely by the forward motion of the fabric. The means for applying tension conveniently consists of a friction brake mounted on the back movement roll. Fig. 1 illustrates diagrammatically a pile cutting machine 1 consisting of two superposed cutting units 2 and 5. The fabric 11 to be cut is fed into the lower rear portion of the machine passes successively into the two cutting units and passes out at the top portion to which is fitted a folding device 12. When it is desired to check the quality of the cutting, operating lever 78 is moved into the back movement position. Automatically the two beds 4 and 7 move away from the cutting cylinders 3 and 6 while the back movement roll 15 is driven in the direction of arrow R to reverse the fabric.

Abstract: 1311154 Felt-pen ink T YOSHIDA 26 May 1970 [27 May 1969] 25207/70 Headings C3F C3P and C3R A felt-pen ink is made by: mixing together 0À1-10% wt. of a polymer, 0À1-10% wt. of a hygroscopic inorganic salt, a dye chemically compatible therewith, and a solvent for these ingredients; and stirring. The polymer has polymerization degree # 150; a 1% wt. solution thereof has a viscosity # 100 cp. at 20‹ C.; this 1% wt. solution is not coagulated even when > 3% wt. water is added thereto. The polymer may be ethylcellulose, methylcellulose, carboxymethylcellulose, acetylbutyl cellulose, a methoxymethylated polyamide, a butylal resin, or a polyvinyl alcohol. The salt may be LiCl, CaCl 2  or Ca(NO 3 ) 2 . The ink may also contain a non- solvent for the polymer; this non-solvent may have a b.p. higher than that of the solvent. The non-solvent may be water absorbed from the air during evaporation of the solvent, or n-butanol. The solvent may have b.p. < 100‹ C. It may be ethyl acetate or methanol. Other, optional, ingredients include a solution of ammonium acetate in methanol as gelling agent, and isopropyl alcohol, n-butanol, and butyl acetate as anti-drying agents. Dyes include fuschin, Varifast Red, Victoria Blue B, Vari-fast Blue, Malachite Green, or Methanyl Yellow. The ink is used on an enamelled writing-board, which may be white. The ink leaves a brittle film on the board, which can easily be erased. The ink also forms a brittle film at the forward end of the felt-pen, thus preventing the ink drying on the pen.
