Title: Process for the manufacture of fashioned articles from fabrics containing artificial filaments, threads, straws and the like
IPC: A41B17/00
Filed: 1936-04-17
Abstract: Three dimensional fashioned articles of wearing-apparel, e.g brassieres, suspensories, hat shapes, caps, girdles, and surgical slings, are made by fashioning fabrics of thermoplastic derivatives of cellulose by distortion of the yarns of the fabrics under such conditions that they are rendered at least partially plastic, and thereafter stitching the articles so as to fix the shape in the articles.  The fashioning may take place before or after the articles are cut from the length of fabric.  The yarns are rendered plastic by heat treatment, if desired in the presence of water or steam, the necessary temperature being lower when water or steam is used. Plasticizers may also be present.  The fashioned article may be stiffened by using such high temperatures during the fashioning as to cause coalescence of the yarns, or there may be applied to the fabric a solvent, a solution of a cellulose derivative, or sizes such as dammar resin, copal resin, elemi resin, or gelatine.  The stitching may comprise only hemming, taping, or sewing on of decorations in the case of small articles.

Title: Improvements in or relating to rolling motion generating gearings for grinding machines and testing apparatus for bevel wheels
IPC: B23F5/02
Filed: 1943-07-13
Abstract: 572,205. Gauges. AEPPLI, A. July 13, 1943, No. 11384. Convention date, July 4, 1942. [Class 106 (ii)] [Also in Group XXII] In a machine for grinding or testing toothed bevel gears, the gear is caused to roll on an imaginary crown wheel by rotation on its own axis and about the.axis of the crown wheel, each rotational movement being imparted to the gear by a shaft extending perpendicular to its respective axis of rotation so that the two shafts lie parallel to each other and are connected by steel tape gearing. The bevel gear 1, Figs. 3 and 9, is mounted on a shaft 25 carried by a frame 9 which is angularly adjustable, to suit the cone angle a of the gear, about trunnions 23 carried by a pillar 8, arcuate slots 27 in the pillar providing for securing of the frame by means of nuts and studs 28. A drum 2 on the shaft 25 is connected by crossed tapes 4 to a drum 6 on a shaft 5 which is perpendicular to the shaft 25 and further tapes 15 connect the shaft 5 to a parallel shaft 10 carrying a drum 12 which is connected by crossed tapes 31 to a drum 7 secured to 'a pivot 21 attached to the machine base 20. On rotation of the pillar 8 about the pivot 21, whose axis passes through the apex x of the bevel gear cone, by means of a worm drive 30 and further gearing (not shown), the tapes 31 cause the gear 1 to be rotated with a rolling motion about the pitch plane p ... p of the crown wheel, the gear ratio of the parallel shafts 5, 10 being equal to the sine of the angle a. The long straight parts of the tape 15 may be stiffened at 15<1> to prevent stretching thereof. When grinding a bevel gear the grinding discs 32 are given the necessary feed movements relatively to the rolling blank 1, and after the generation of a tooth flank the blank is indexed, whilst the discs are withdrawn. During a reverse rotation the discs may re-grind the same tooth flank or grind an adjacent flank. For testing gears a feeler is substituted for the grinding disc and is displaced if the tooth flank differs from the correct shape. The feeler movements may be registered on a recording drum. In a modified construction the drive 15 between the shafts 5, 10 is replaced by tapes 114, Fig. 4, connected to the drums 112, 113 and to an arcuate member 16 pivoted on the trunnions 23, or the tapes 114 may be connected to an inclined slide 34, Fig. 6. In another modification the work shaft 25 is.connected to the shaft 5 by spur gears 17, 18, Fig. 8, and a reciprocable rack 19 which is toothed along two adjacent sides, and a similar connection may be made between the shaft 10 and pivot 21.

IPC: B01D3/42
Filed: 1957-04-11
Abstract: 842,335. Automatic control systems. ESSO RESEARCH & ENGINEERING CO. Jan. 17, 1958 [April 11, 1957], No. 11923/57. Class 38(4). A still is maintained at its optimum temperature just below that which will precede flooding of the fractionating column by measuring the rate of reflux and controlling the temperature accordingly. As shown, a syphon near the base of the column alternately fills and empties and so alters the capacitance between foil sheets 6, 7. The capacity change causes an oscillator to start or stop oscillating, the change in oscillator current operating a relay to produce square pulses. The positive pulses obtained by differentiating these pulses trigger a monostable circuit the output of which thus consists of pulses of equal amplitude and duration and a frequency equal to the frequency of operation of the siphon. These pulses after smoothing produce a voltage representative of the rate of reflux and this controls the heat supplied to an immersion heater and a jacket heater by comparison with a pre-set voltage modified by a feed-back voltage from one of the heater supply circuits.
