Title: Improvements in or relating to machines for coating workpieces
IPC: A43D25/18
Filed: 1950-08-03
Abstract: <PICT:0703163/III/1> <PICT:0703163/III/2> A machine for coating workpieces comprises a pair of co-operating feed rolls which are adapted to direct workpieces to a separate coating-applying roll supplied with coating material from a receptacle, the machine being so organised as to cause coating material to be applied to one side of a workpiece as the latter is fed to the coating-applying roll by the feed rolls, wherein one of the feed rolls is supported, with its axis parallel with the axis of the applying roll and with the axis of the other feed roll, by a supporting member which is pivotally mounted for movement about an axis parallel with the axis of the feed rolls, in a carrier which is tiltable about the axis of said other feed roll, the arrangement being such that tilting movement of the carrier about the axis of said other feed roll is effective adjustably to determine the angle of presentation of the workpiece to the applying roll while pivotal movement of the supporting member with respect to the carrier is effective to vary the spacing between the feed rolls, any such movement of the carrier and supporting member being made without disturbing the driving means for the feed rolls.  A workpiece is presented to the feed rolls 28 and 30 (Fig. 8) on a table 32, the feed rolls being held in a carrier 180 tiltable about the axis of a shaft 102 carrying the lower feed roll 28.  The upper feed roll 30 is carried on a shaft 194 between the arms of a yoke 196, which is tiltably mounted in the carrier 180 to rotate about a shaft 197 journalled in the end members of the carrier, allowing variation in spacing between the feed rolls.  The carrier may be tilted forward to hold limp workpieces in firmer contact with the applying roll 24 or may be tilted in a clockwise direction from the position in Fig. 8 to one where the rolls are more nearly above one another.  Gears are arranged to allow adjustment of the carrier without disturbing the driving means for the feed rolls and without affecting the spacing between them.  The applying roll 24 picks up cement from a tray 50, which has a cup-like portion 58 (Fig. 3) above which is a cage 60 holding a cement bottle having a barometric feed type valve 64 at its mouth 62, which maintains a constant level in tray 50.  The cage 60 is secured to a block 66 pivoted for tilting movement about a screw stud 70.  The cage may be tilted to the position shown in broken lines in Fig. 3 to remove tray 50 for cleaning. When a relatively large quantity of cement is to be applied the applying roll 24 (Fig. 8) rotates so that its upper surface moves counter to the work; a stripper roll 26 rotates on the upgoing side of the roll controlling the amount of cement carried by the roll. When less cement is to be applied the roll rotates with the direction of movement of the work, and stripper roll 26 is swung to the other side of the applying roll, gear changes being made to drive roll 26 in the opposite direction to the applying roll. Specification 544,487 is referred to.

Title: Improved process and apparatus for generating motive fluid, particularly designed for the heating apparatus of torpedo engines
IPC: F22G1/00
Filed: 1920-07-08
Abstract: 147,518. Whitehead & Co., Akt.-Ges. Feb. 18, 1915, [Convention date]. Furnace gases and the like, mixing steam with. -In a steam generator for torpedoes, in which highly superheated steam is combined with combustion gases and employed for driving the engines, the water, after passing around the sides of the combustion chamber is led through water tubes extending across the latter at the end opposite the flame entrance into an annular collecting chamber arranged inside and passes out through perforations towards the flame. The burner t is situated in the cover f and air enters through holes h in the perforated diaphragm arranged in the cover. The water enters under a pressure at the inlet g into an annular space in the cover, before passing through the ring of holes r into the helical passages w formed by ribs c on the inner casing n. During its passage through the helical passage w the water is heated to the vaporising temperature corresponding to the pressure, and is converted partly into saturated steam. This steam, together with any liquid which has not been vaporised, flows through tubes z where it is superheated. This superheated steam collects in the annular space o, and flows out through the nozzleapertures of the annular belt u in the form of a conical sheaf concentric to the flame t and is converted into highly superheated steam which becomes intimately mixed with the heated air and products of combustion, and is conveyed together with the latter through the outlet opposite the burner t.

Title: Lacquers that produce photo-polymerisable coatings
Inventor: PIETSCH HERWARD
IPC: C08F8/00
Filed: 1966-05-03
Abstract: A lacquer which produces photo-polymerizable coatings has a film-forming base consisting essentially of polyvinyl alcohol of which at least 20% of the hydroxyl groups are etherified with ethylenically unsaturated organic radicals and any remaining hydroxyl groups are free or wholly or partly esterified and/or acetalized with saturated or unsaturated alkyl or aralkyl groups. Suitable groups for the esterification or acetalization are residues of crotonic, acetic, cinnamic, benzoic, and substituted benzoic acids, crotonaldehyde, acrolein, benzaldehyde and substituted benzaldehyde. In Examples 1 and 2 polyvinyl allyl ether is prepared by adding a solution of metallic sodium in ammonia to a solution of polyvinyl alcohol in ammonia and reacting the sodium polyvinyl alcoholate with allyl bromide. In Example 3 polyvinyl cinnamyl ether is prepared by adding a solution of sodium ethoxide in dimethyl sulphoxide to a solution of polyvinyl alcohol in dimethyl sulphoxide and treating the sodium derivative with cinnamyl bromide in dimethyl sulphoxide.  The polymers are dissolved in glacial acetic acid or ethanol and Nichler's ketone may be added. Coatings made from the lacquers are hardened by exposure to light.

Abstract: 389,706. Cameras mounted on moving vehicles. THUN, S., Schloss Weissenau, near Wolfsberg, Corinthia, Austria. July 2, 1932, No. 19574. Convention date, July 14, 1931. [Class 98 (i).] Relates to devices for taking photographs from a moving vehicle. According to the invention, the releasing and controlling mechanism for taking a picture, and for feeding the film after exposure, is actuated automatically when the braking mechanism of the vehicle is quickly applied. In one construction, the camera A, Fig. 2, is pivotally mounted in a forked member 7 which is carried by a bracket 3 secured to the frame 1 of the windscreen. The camera and bracket are locked in the required positions by nuts 10, 8. As shown diagrammatically in Fig. 4, the lens cap 11 and film winding spool 23 are connected by links 19, 20, 21 to the armature 18 of a solenoid 17. When the circuit of the solenoid is closed the armature is moved to the position 18<1>. During this movement the lens cap 11 is raised clear of the lens 12, a ratchet wheel 22 on the shaft of the spool 23 is rotated by the link 21, and the link 20 moves a further link 27 to actuate the shutter 28. Upon opening the circuit the parts of the mechanism are returned to the position shown by a coiled spring T, and during the return movement a fresh film is fed into position by the engagement of a ratchet tooth 24 on the spool 23 with the ratchet wheel 22. The circuit of the solenoid is closed, according to one construction, by a member 32, Fig. 5, connected to governor balls 31 mounted on a shaft which is connected by gearing to the brake 30 of the vehicle. The member 32 is so arranged that is closes the circuit only upon a sudden application of the brakes. In a modification, a spring-actuated, weighted lever swings forward to close the circuit when the vehicle is suddenly retarded. The Specification as open to inspection under Sect. 91 describes an arrangement wherein the circuit is closed manually by push buttons mounted on the dashboard. In a modified arrangement the electric circuit is dispensed with and the camera mechanism is actuated by a manually operated flexible wire. This subjectmatter does not appear in the Specification as accepted.
