A feed mechanism for a press of the type which includes a feed arm reciprocable between a pick-up point and a delivering point includes primary fluid-operated means adapted to reciprocate the feed arm, secondary fluidoperated means adapted to control the lifting and lowering of the feed arm at each of said points, control means being provided whereby the press is actuated to perform a working stroke upon the feed arm having effected a predetermined movement. The feed mechanism includes a mounting plate 10 located on or adjacent to the press so that the feed arm 11 may be reciprocated between the press tools and a feed table or magazine. The feed arm 11 is pivoted on a pivot head 12 which accommodates a spring 13 for urging the feed arm towards its lower or pick-up position. The feed arm may be provided at its operative end with a suction cup, a pair of gripper fingers or an electromagnet. The other end of the feed arm is adjustably secured to a link 15 attached to a main slide block 17 by means of a spring- loaded adjustable abutment 18. The slide block 17 is actuated to feed a workpiece to the press tools by a pneumatic double-acting motor 26 controlled through a valve 30 operated by a cam on the crank-shaft of the press. When the feed arm reaches its delivery position a cam 31 on the slide actuates the valve 30 to return the slide and feed arm to their initial positions. During the return movement of the slide a pivoted trigger cam 32 on the slide operates the press trip valve 33 controlling the clutch pedal of the press. A second air motor 35 is associated with the pivot head of the feed arm to raise the feed arm as it moves from the pick-up to the delivery positions. This motor is operated by a double-ended cam on the slide 17. The suction cup on the feed arm is operated from a vacuum producer 40 controlled through a valve 41 operated by stops 42 on the slide 17. A cam 46 on the slide 17 operates a valve 45 for controlling the movement of the magazine feed or rotation of the feed table in timed relationship with the movement of the feed arm. A manually-controlled master valve ensures that the feed arm comes to rest in the pick-up position. In a modification, the feed arm is provided with a pinion 50 (Fig. 6), which is operated by a rack 51 resiliently attached to the slide 17.

Filed: 1923-04-04
Abstract: 215,166. Fairweather, W. C., (Underwood Typewriter Co.). April 4, 1923. Paper-carriages. - Supporting and guiding rollers for the front or other parts of typewriter carriages, of the kind comprising a peripheral roller 1 supported by balls 5 on two cones 3, 4 mounted on a stud 12, are retained as units for attachment to or detachment from the carriage by a collar 14 of lead or other soft metal received completely in a recess 16 in one cone 4. The collar 14 is originally of thickness equal to the depth of the recess 16 and slides into the recess over the stem 12, the collar being pressed into engagement with the abrupt side walls of the recess 16 and with the screw-threaded stem 12, and being then of thickness less than the depth of the recess. The head 9 of the stud 12 is received in a recess 6 in the cone 3 not co-operating with the collar 14, and the stud 12 projects through the cones 3. 4 and through a cone-spacer 13 and the collar 14, and is screwed into a threaded hole in the carriage. Accidental displacement of the cone, 3, 4 during attachment of the roller to the carriage, liable to occur when a temporary nut on the stem 12 is used to prevent this displacement prior to the attachment, is thus prevented. The spacer 13 is of soft metal or other deformable material, but is preferably of harder material than the collar 14. Play of the balls 5 in the raceway formed by the cones 3, 4 and by an interior groove 2 in the roller 1 is taken up by tightening the stud 12 on the carriage and compressing the spacer 13, the collar 14 allowing this tightening.

Abstract: 374,979. Cables. BEAVER, C. J., Bell Place, Stamford Road, FAIRFIELD, T. J., Newlands, Talbot Road, both in Bowdon, Cheshire, and GLOVER & CO., Ltd., W. T., Trafford Park, Manchester. March 26, 1931, No. 9280. [Class 36.] In an impregnated cable having disposed within it a series of circumferentially corrugated cylindrical or prismatic gas-filled pressure compensators, over-compression of the compensators is prevented by b nding the wall of each ring of corrugations through an angle greater than 180‹. Fig. 1 shows a compensator comprising a corrugated thin walled cylinder 1 closed at its ends by caps 2, each provided with a hook 7 for connection to an adjacent compensator. The corrugations on the cylinder 1 may be separate from each other or may be in the form of one or more continuous helices of short pitch. Each complete corrugation consists of an inner ring 3 and an outer ring 4, as shown in Fig. 2, which are formed by bending the metal through an angle 6 greater than 180‹. so that the rings 3, 4 overlap in a longitudinal direction. The angle 6 is so chosen that full compression of the compensator, as shown in Fig. 3, does not cause the elastic limit of the material to be exceeded. The compensators may be arranged in cages. Correct spacing of the corrugations, prior to the insertion of a compensator within a cable, may be obtained by stretching the compensator to a length exceeding the maximum of that which it attains in the cable under working conditions and then subjecting it to an external fluid pressure sufficient to produce full compression of the compensator, whereon the pressure is released.

[Also in Divisions B5 and C3] Reinforcing materials such as silica cloth and carbon cloth are impregnated with a composition comprising a mixture of a polyfunctional diene prepolymer having at least 50% of its olefinic unsaturation in the form of pendant vinyl groups on alternate carbon atoms of an elongate backbone chain, a polyfunctional organic chain extender capable of reacting therewith, and a peroxide free radical initiator capable of curing the mixture to a hard resin. Suitable diene prepolymers are from 1,2-polybutadiene, 1,2-polyisoprene, and 3,4-polyisoprene. The functional groups on the prepolymer are hydroxyl, amino, or carboxyl groups and the chain extender is a polyisocyanate, polybasic acid, anhydride, or acid chloride, epoxy compound, imine, or imide. The first reaction is chain extension to form an elastomeric matrix having the peroxide dispersed therethrough. On further heating the mixture cures, perhaps by cyclization. The two reactions may occur simultaneously.

Abstract: 513,001. Fluid-pressure relays. ASKANIAWERKE AKT.-GES. VORM. CENTRALWERKSTATT DESSAU UND C. BAMBERGFRIEDENAU. March 28, 1938, No. 9502. Convention date, April 12, 1937. [Class 135] A fluid-pressure relay has a main conduit 1 fed by an auxiliary pressure fluid the flow of which is influenced solely by throttling means, e.g., the baffle plate 4, operated by control or regulating impulses, and a constriction 7 in the main conduit in front of the throttling means, a control conduit branching from the main conduit in the region of lowest pressure therein the pressure in the-branch conduit being dependent on the flow in the main conduit and acting on a servomotor 8 which operates a regulating device. As shown in Fig. 4, the constriction is in the form of a Venturi tube 7 and the control conduit 9 leading to the servomotor 8 branches off, at its narrowest point. The outlet from the main conduit 1 is controlled by a baffle plate 4 carried by a lever 6 actuated by changes in impulse in a chamber 5. The control pressure in the conduit 9 acts on a membrance 10 to counterbalance the effect of the primary impulse on the baffle plate 4. The membrance 10 may however be omitted. The baffle plate 4 may be replaced by a sliding gate closure, and the constriction may be formed as an orifice plate. Fig. 2 demonstrates the pressure conditions in front of and behind the constriction. The ratio p1<1>/p2 of the manometer readings before the constriction and at a point C removed from the constriction tends to a minimum valve as the stroke h of the baffle 4 increases but the same ratio p1/p2 for a point B adjacent the constriction decreases to zero and even assumes negative valves so that the operating range of the relay is thereby increased. Fig. 7 shows a differential arrangement for remote control systems such as tele-compass systems. An eccentric disc 12 coupled to a compass needle 13 differentially controls outlet ports 3a, 3b in two main conduits 1a, 1b having constrictions 7a, 7b near which branch control conduits 9a, 9b.

Abstract: 308,649. Soc. Anon. des Etablissements Industriels de E. C. Grammont et de A. Grammont. March 24, 1928, [Convention date]. Vacuum tubes.-Cathodes are prepared by coating a wire with a metal, such as gold, with which mercury will amalgamate, depositing electrolytically thereon one or more of the alkali or alkaline-earth metals, and finally, when the wire so treated is to be stored, providing a protective coating. The electrolyte may be constituted by a saturated solution of a chloride of. for example, barium, strontium, caesium or rubidium, or by a mixture of such salts, and the anode may be formed by a precious metal such as platinum or iridium or a mixture thereof. By heating the wire in a vacuum or in an atmosphere of hydrogen, the mercury is driven off and an alloy of the metal support and the emissive material is obtained, or the wire mav be heated in the valve envelope by radiation, by direct or eddy currents, or by electron bombardment. In the apparatus shown, the process is carried out continuously, gold or gold-coated wire 1 being drawn from a reel 2 through a mercury bath 3 which is covered by a scouring solution 4, consisting, for example, of aqua-regia, over a reel 6 and through the electrolyte 7, the electrode 8 of which is connected to a source of current 9 and to the mercury 3. A protective coating is applied by a liquid 12, of less density than the electrolyte, which may be a solution of cellulose acetate or celluloid and is contained in a receptacle 11 communicating with the electrolyte container. It is stated that the wire may be passed successively through different electrolytes. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of other metals having a high electron-emitting capacity.
