Title: Improvements in or relating to drilling and like machines
IPC: B23B39/00
Filed: 1927-11-18
Abstract: 292,411. Rawnsley, R. V. Nov. 18, 1927. Drilling-machines. - In a drilling or like machine wherein the spindle is rotatably mounted on the feed screw which is rotated intermittently from the main driving shaft, means are provided for locking the spindle and screw together so that when the intermittent feed is thrown out of gear the two may be rotated as a unit from the main drive in order to advance or withdraw the spindle rapidly. The machine may be hand or power operated and may be portable or of the bench type. In a machine of the latter type, the spindle 7 is driven by bevel gearing 15 from a hand wheel 13 and is rotatably mounted within a screwed feeding sleeve 6 which engages a screwed bearing 4 on the frame 3. Axial movement of the spindle in the sleeve is prevented by nuts 11 and the thrust is transmitted through a ball bearing 10. An eccentric cam 16 on the main driving shaft 9 oscillates a lever 17 pivoted at 18 on the frame and causes a pawl 19 thereon to impart an intermittent feed to the sleeve 6 through a ratchet wheel 20. A hand wheel 21 keyed to the sleeve provides for hand rotation and locking to the spindle is effected by a nut 22 engaging a screwed extremity 7<x> on the spindle and pressing against the hand wheel. The intermittent feed may be thrown out of gear by swinging the pawl out of contact with its ratchet wheel or by moving the lever axially on its pivot, and clutch means other than the nut 22 may be provided for locking the spindle and feed screw together.

Abstract: 957,167. Door fastenings. WILMOTBREEDEN Ltd. Sept. 9, 1960 [Sept. 11, 1959], No. 30996/59. Heading E2A. A "no-torque" door fastening for rail vehicles comprises a G-shaped striker plate 10 which is stepped to provide surfaces in three parallel planes and co-operates with a rotary cam bolt having two surfaces 22, 23 projecting for different distances in the axial direction so as to complement two of the striker plate surfaces. On closing, initial contact between the trailing lobe 22 of the bolt and the bulge 15 of the striker upper jaw 14 aligns the bolt for entry. The upstanding surfaces 18, 24 on the striker and bolt respectively then engage as shown in Fig. 6 and rotate the bolt into the coupling position, Fig. 7, in which the upstanding surfaces 21, 25 engage; the reaction between them is substantially through the rotational axis X-X of the bolt, Figs. 6 and 7. Should the door be slammed with insufficient force to engage the catch a position of safety lock is provided, Fig. 8, when the trailing lobe 22 of the bolt engages behind the bulge 15 while the leading lobe 23 rests on the tail 19; spring loading of the bolt acts to retain the lobe and tail 23, 19 in contact while the reaction at 15, 22 passes through the rotational axis of the bolt so that there is no disengaging torque. Specifications 864,305 and 871,895 are referred to.

Abstract: 230,019. Naamlooze Vennootschap Werktuigenfabriek Rotator. Feb. 27, 1924, [Convention date]. Void [Published under Sect. 91 of the Act]. Blowpipe burners.-Combustible gas is introduced into the inner tube 3 of the burner, the oxidizing and aspiring gas passing into the surrounding passage 6. The relative position of the gases is reversed before they are mixed, the flow of oxidizing gas through a central pipe 7 inducing a flow of combustible gas into an annular space 8. By this means the relative proportion of the gases remains substantially constant notwithstanding heating of the burner. The mixing space 9 is surrounded by heat-insulating material 11. The two gas cocks are coupled together by a stirrup 12 having a bracket 13 through which a shaft 14 is journaled. By turning a milled head 15, a worm wheel 17 fixed on a square on one of the cocks is rotated, thus allowing for the adjustment of one cock independently of the other.

Title: Improvements in the manufacture of colour printed fabrics
IPC: B41F17/00
Filed: 1927-11-22
Abstract: 292,415. Morton, J. Nov. 22, 1927. Discharge and like printing ; resist printing.- Fabrics are. woven with a design by means of jacquard or like selecting-mechanism and are then printed to produce a coloured pattern by rollers or blocks which serve, only to apply the colours and not to form a particular design, the yarns or threads of the fabric having been so treated that the ground or other part obscures, neutralizes, or changes the colours applied. The ground may be woven in dark-coloured threads and the pattern left white, so that when printed, the white design will be coloured but the dark back ground will mask the colours applied; alternatively the threads can be chemically or mechanically treated. The printing rollers or blocks are not cut or etched with a particular design to be applied, but with some simple design adapted only to take up and then apply and distribute the colours. Fabrics with mixed fibres may be made with one coloured design on one fibre and a different coloured design on the other fibre.

Steam - - pressure sprayers. - Apparatus for purifying, moistening, disinfecting, or perfuming air comprises a steam-jet apparatus supplied from an electrically - heated boiler and a nozzle directed toward the path of the steam for suction and emission of a liquid to be atomized. The boiler comprises two concentric water-containers 1, 2 with an air space between them and connected by pipes 4, 5 respectively above and below the water level. Steam is generated in the inner vessel 1 and escapes through an upwardly-turned jet 12 mounted above a nozzle 13 on a tube which is immersed in the liquid to be atomized in an annular vessel 6 surrounding the boiler. The water in the boiler is heated electrically by a coil 10, the apparatus being so arranged that the circuit is broken when the level of water in the boiler falls below a predetermined level.

An inert filler, a solid fatty acid having at least 10 carbon atoms and an emulsifying agent for said acid may be included.  The tablet slowly disintegrates as it passes through the gastro-intestinal tract, the rate of disintegration being controlled by the proportion of aluminium hydroxide gel, which may range from 10 to 30% by weight and by inclusion of a saturated fatty acid having at least 10 carbon atoms in the proportion of 10 to 30% by weight.  The binder may be, for example, a sugar syrup, a gum, carboxymethyl cellulose in the proportion of 10 to 20% by weight; the inert filler may be, for example, di- or tri-calcium phosphate, kaolin or calcium sulphate. The emulsifying agent, advantageously added in the proportion of 3 to 10% by weight when a fatty acid is included, may be sodium taurocholate or sodium glycocholate.  Examples of the composition and preparation of various tablets are given which show disintegration times in synthetic gastric juice ranging from 9 to 29 hours.
