Title: Improvements in or relating to printing machines
IPC: B41L15/02
Filed: 1928-02-16
Abstract: 295,350. Hubbard, H. E., McCain, C. C., and Thompson, H. L. Aug. 10, 1927, [Convention date]. Ink-ribbon mechanism.-An office or like printing-machine for printing cards, envelopes, &c. from a forme and ink-ribbon is constructed with a bed 2, Figs. 1 and 4, on a main frame 1 and a skeleton ribbon frame 4 pivoted by means of ears 7 formed with angular slots 8 engaging a cross bar 5, the frame being normally held in operative position by a spring catch 6 engaging the frame 1. The frame 4 is turned to the dotted line position, Fig. 4, to allow of access to the forme or to change the ribbon. The ribbon passes over curved guides 17 at each end of the bed, and the frame 4 is held under tension by spring- pressed posts 20. In an office or like printing- machine, the ink-ribbon 10 is mounted on spools 11, 11<1>, Figs. 4 and 9, in a frame 4 detachably connected in the frame 1, each spool being detachably connected to a driving-ratchet 12, or 12<1>, and being held in operative position by a spring-pressed plate 14 with a projection 13 which engages the inside of the spool. To drive the spools, one of the ratchets 12, 12' is engaged by a dog 56, or 56<1>, mounted on a laterally movable slide carried by a plate 57 attached to the carriage 23. This slide is automatically moved alternately in opposite directions to reverse the feed by means of cam-surfaces 64<11>, 65<11>, on levers 64, 65 which are gravity-controlled and provided with rollers 64<1>, 65<1>, for engaging the spools. When one of the spools, e.g. 11<1>, is low and reversal of feed is necessary, the cam-surface 64" shifts the slide carrying the dogs laterally and the dog 56<1> is caused to engage ratchets 12<1> so that winding-up occurs on spool 11<1> instead of spool 11.

Title: Sewing machine
IPC: D05B71/00
Filed: 1939-02-16
Abstract: 514,232. Sewing-machines. SINGER MANUFACTURING CO. Feb. 16, 1939, No. 5075. Convention date, June 2, 1938. [Class 112] The feeding mechanism of a sewing machine is enclosed in an oil chamber in the machine frame except for a member which passes through an opening in the chamber to actuate the feed element, means being provided to effect an oiltight seal about the member where it passes through the opening. The feed mechanism is modified to give the feed dog a more nearly horizontal movement during its working stroke. Means are provided for cooling the mechanism by air currents. The presser-foot is tiliably adjustable on the presser-bar. Feed.-The feed-dog 27 is fixed to the end of a feed-bar 31 which extends longitudinally of the machine through an aperture 68, large enough to accommodate all its movements, in the wall of a closed oil-chamber 30 formed in the machine base and containing the feed-mechanism. The feed-bar 31 is clamped in a block 62 integral with a rod 58 which is slidable in a pivotally-mounted sleeve 59 and the strap of the feed-lift eccentric 55 on the looper shaft 21. The feed - bar also engages an eye on a rod 37 slidable in a member 38 pivoted at 40 and actuated from the feedadvance eccentric 44 on the shaft 21 through a pitman 43 and slotted arm 42. The length of the feed stroke is varied by shifting the lower end of the pitman 43 along the arm 42 by means of a link 52 and an arm on a rock-shaft 50 actuated by the usual adjusting lever in the standard of the machine. The tendency of the feed-dog to drop towards the end of the feed-stroke, due to the action of the eccentric 55, is counteracted by inclining the rod 58 so that the feed-bar rises as it moves forward. The feed-rocker 38 is provided with a balance weight 67 to reduce vibration. Lubrication.-The chamber 30 contains oil, as shown in Fig. 7, which is splashed over the mechanism by the arm 42 and counterweight 67. The oil is prevented from passing through the opening 68 in which the feed-bar operates by a sealing plate 69 carried on the feed-bar and spring-pressed against the inner side of the chamber wall and by an enlarged part 31' of the feed-bar bearing in an undercut recess 70 in the outer side of the wall; a wick-filled passage (not shown) is provided to drain oil from the recess 70 back into the chamber 30. Oil is prevented from passing along the bearing of the looper shaft 21 by a thrower ring 80 and an intercepting groove 82 draining back into the chamber 30. The oil and mechanism are cooled by a current of air induced by a fan 74 on the shaft 21, air inlet and outlet ducts being formed in the frame close to the fan. A dipstick 75 is provided. Presser-feet.-The presser-foot 12, Fig. 11, has a thin slotted shank clamped by a screw 11 in the slotted end of the presser-bar 10. In order to allow adjustment of the foot to cause the toe or heel to bear more heavily on the work the foot carries a pair of stop screws 13, the heads of which engage opposite sides of the presserbar 10.

Filed: 1942-04-17
Abstract: 556,764. Two-stroke engines. AKTIEBOLAGET GOTAVERKEN. April 17, 1942, No. 5163. Convention date, April 23, 1941. [Class 7 (ii)] In a single-acting twostroke engine in which each working piston 6 compresses scavenging and charging air in a compression chamber 17, one or more compression cylinders 20 are provided at the side of the engine cylinder 7 and air is discharged from the space 17 and the cylinders 20 into a chamber 28 surrounding the engine cylinders, which have piston-controlled inlet ports 10. As shown, the chamber 28 is formed by a rectangular casing 27 enclosing the cylinders 7, 20 and the chamber 17 is separated by a wall 18 from the crankcase 2. The lower end of the compressor cylinder 20 is open to the chamber 17 and air is discharged from the chamber 17 and the upper end of the cylinder 20 through valves 26, 29. The engine and compressor pistons are connected to a crosshead 8 moving on guides 9. A conduit 30 for supplying cooling medium to the piston 6 occupies one corner of the chamber 28. To prevent admission of air from the chamber 28 through the ports 10 to the chamber 17 when the piston 6 is in its upper dead-centre position, a sleeve 31 controlling the ports 10 is actuated by rods 14 connecting the valve levers 15 to cross-bars 13 carrying the exhaust valves 12.

Part of this light is reflected by mirror 19 to lens 20, and concave mirror 21, and back to screen 24 of observing device 23. Also light from the film passes back through lens 22 and is reflected by mirror 19 to screen 24. To dim the primary image on the screen to the same intensity as the second one coming from the film, the concave mirror 21 is preferably blackened. In other forms, the mirrors 19, 21 and lens 20 of Fig. 1 are replaced by a compound prism, of which various forms are shown.

Title: Improvements in or relating to the production of cross linked polyurethane syntheticmaterials
IPC: C08K3/38
Filed: 1958-02-19
Abstract: In a method for the production of cross-linked polyurethane synthetic materials by a poly addition reaction of a polyester and a polyisocyanate, phosphoric or boric acids obtained by condensation or polymerization, or salts of such acids are added to the polyester before the poly addition reaction and a cross-linking agent, such for example as a dihydric or polyhydric alcohol is added to the mixture to bring about the cross-linking reaction.  As the materials to be added there may be used glass-like polymeric bodies known as "borax or microcosmic salt beads" obtained by heating potassium metaphosphate or borates, for example borax.  A suitable polyester is that of glycol and adipic acid.  With it there may be mixed silicic acid, aluminium or calcium silicate, magnesium oxide, alumina gel, hydrophilic carbon black, cobalt, lead or zinc naphthenates, linoleates, compounds of resinic acid or octoates of synthetic isocarbonic acids.  The added fillers may contain up to about 12% of water. In an example (1) an adipic acid ethylene glycol polyester is melted at 120 degrees with polymeric potassium metaphosphate and zinc naphthenate and dehydrated.  Napthalene 1,5-diisocyanate is stirred in followed by butylene glycol and the mixture is poured into a mould and heated.  The products are useful as soling and heeling materials, linings and coverings and buffers.ALSO:In a method for the production of cross-linked polyurethane p  synthetic materials (which may be formed by a polyaddition reaction of a polyester and a polyisocyanate, phosphoric or boric acids obtained by condensation or polymerisation or salts of such acids are added to the polyester before the polyaddition reaction and a cross-linking agent, such for example as a dihydric or polyhydric alcohol is added to the mixture to bring about the cross-linking reaction.
