Title: Processes for manufacturing lace fringes or other ornaments and articles produced by such processes
IPC: D04D5/00
Filed: 1926-07-16
Abstract: 264,399. Soc. Anon. Rodier. June 3, 1926, [Convention date]. Fringes.-A method of manufacturing a lace fringe, such as is shown in Fig. 5, comprising a series of undulated tubular cords consists in first weaving a temporary fabric with selvedges 1<1> and 1<2> as shown in Fig. 2 using an auxiliary thread 3. Subsequently the thread is removed from the whole of the fabric and One selvedge 1<2> whereupon the tubular cords 2 remain as undulated fringes supported by the selvedge 1'. The temporary fabric may be immersed in liquid such as a dye bath or water or may be subjected to steam action, thereby increasing the undulatory appearance of the threads. The temporary fabric may be printed, which results in a more regular action on the tubular cords than printing on the cords without forming a temporary fabric.

Title: Process of refining oils and the like by steam treatment
IPC: B01D11/04
Filed: 1931-06-23
Abstract: <PICT:0386993/III/1> Oils, coal pastes, &c. are treated with steam at 200 atmospheres and a temperature exceeding 500 DEG  C. in a reaction chamber, the major portion of the steam being condensed into water under pressure by the transference of heat to the oil.  Gases, such as air, hydrogen, ammonia, coal gas, &c., may be supplied and the coal paste may be treated with hydrogen-containing bodies such as formates or hydrides.  Steam at 200 atmospheres and superheated to 500 DEG  C. or more is led to a reaction vessel 1 from which it passes by a pipe 14 into a dephlegmator 3.  Oil is fed to the dephlegmator by a pipe 13 and passes therefrom to the reaction chamber by a pipe 15, the lower part of the dephlegmator being occupied by condensed steam 4 above which is a layer of oil 5. The condensed steam passes to a chamber 6 and thence by a pump 11 to the generator or it may pass through a preheater 7 for the feedwater.  A lower temperature may be produced in the dephlegmator by throttling the entering steam or by passing the feedwater through a coil 10 in the top of the dephlegmator.  The oil vapours formed leave by a pipe 16.

A motor drives a gear 16 and, through other gears 15, 14, 9, the drum and the sprocket. The magnetic drive to the drum from the gear 14 is as described in Specification 316,320, [Class 97 (i)]. The rollers 23, 24 are carried on spring- urged arms 42, 65, the former being axially adjustable on its pivot. Members 47, 63 on the base-plate have bent-up ends to limit the movement of the roller arms. A device 35 projects images of indicia, set at 38, through a lens 39 on to the film for identification purposes. A film punch is operated by a solenoid 34. A footage indicator is provided at 31. The Specification as open to inspection under Sect. 91 describes a modification in which the idler rollers are replaced by a single sprocket spring-urged away from the drum and engaging the film passing to and from the drum. In a further modification, two sprockets, geared together, engage these two film portions and one is mounted on an arm pivoted at the axis of the other and spring-urged away from the drum. In these modifications, the drum is film driven. This subject-matter does not appear in the Specification as accepted.

Candles, imitation. - A bulb having a contour closely approximating to that of the flame of a wick candle is mounted at the tip of a candle-like body portion, the bulb at the point of connection with the body being constricted to the diameter of a candle wick. Alternatively, the candle-like impression may be obtained by enclosing a small bulb 45, Fig. 6, in a wrapper 46 shaped as shown at 30, Fig. 4, and comprising paper or like material dipped in a binder of shellac or other varnish, or comprising a shell formed of two parts 47, 48, Fig. 11, adapted to be placed around the bulb and cemented together. The division between the parts 47, 48 may be horizontal or vertical. The candle body may comprise a paper tube 14, Fig. 3, coated with paraffin, or a wooden core 27, Fig. 4, inside a tube 28 or paraffin. The wires from the bulb pass into the candle body in the form of a wick, and may extend directly to the securing means at the bottom of the candle, as shown in Fig. 3. A form wherein the bulb may be renewed without renewing the candle body is shown in Fig. 6, the wires from the bulb being connected to metal rings 38, 39 on a plug adapted to be inserted in a tube 36 mounted in the top of the candle body. The rings 38, 39 connect with rings 43, 44 mounted on the tube 36 and connected with the leads 40.
