IPC: A41B5/00
Filed: 1916-11-08
Abstract: 110,942. Jackson, W. J. Mellersh-, (Heusen, J. M. van). Nov. 8, 1916. Fashioned fabrics; fashioning, weaving to facilitate.-The outer fold of a double collar or cuff is woven under greater tension than the inner fold by means of parts g, h, Fig. 2, of different diameters on the forming- roll of the loom. The fabric is fed over the roll in strip form or as several meters on the forming, one sheet, the part b forming the outer fold and the part a the inner fold of each strip. At the line of fold, some of the warp threads of the intermediate or outer plies are omitted and those remaining are not interwoven with the weft. The outer or face side at the folded edge of a collar made from multiple-ply layers has the warp and weft threads interwoven with one another, and the weakening effected by manipulating the warps in the inner layer only. Collars or cuffs thus made retain their shapes without the use of a stiffening-agent.

Patent GB-322465-A (GB)
Title: Improvements in the production of valuable products from organised substances
IPC: C07J75/00
Filed: 1928-06-02
Abstract: 322,465. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). June 2, 1928. Sterols &c.-Valuable products such as sterols and degradation products of albumens are obtained from organized substances by degrading the bulk of the cell walls by autolysis or by a protracted enzymatic treatment, into water insoluble products, separating the water soluble from the water insoluble products and treating the latter with a practically anhydrous organic solvent, preferably after a treatment with an alkaline agent. The enzymes required may be produced by adding cultures of bacteria forming enzymes capable of degrading the cell walls of the initial material, which bacteria have been previously grown on the organized substances to be acted upon. Thus, the autolysis of the cells of yeast may be performed by mixing the yeast with cultures of bacillus subtiles, bacillus mycoides or bacillus mesentericus which have been grown on autolyzed yeast. By-products such as tyrosine, or purine derivatives such as xanthine and the like, may be recovered. In examples, (1) yeast is subjected to a fargoing autolysis which may be initiated by acetic ester and extracted with an excess of alcohol to obtain the ergosterol ester which is saponified and the ergosterol ethered out. (2) Yeast is autolyzed with a cell poison such as ethyl acetate or chloroform and mixed with a culture of bacillus subtilis grown on autolyzed yeast. Part of the liquified mass is separated mechanically and the residue is worked up as before for ergosterol. (3) Yeast is liquefied by ethyl acetate until tyrosine begins to separate out, and the liquid autolysate free from tyrosine is centrifuged to separate the undissolved fraction which contains the whole of the ergosterol ester. Other valuable substances such as leucine can be recovered by the usual methods and also all the usual cleavage products of yeast. The ergosterol may be recovered from the separated crude product by esterification with acetic anhydride and saponifying.

Title: Work-feeding mechanism for sewing machines
IPC: D05B73/12
Filed: 1943-04-14
Abstract: 565,668. Buttonhole sewing-machines. FAIRWEATHER, W. C. (Singer Manufacturing Co.). April 14, 1943, No. 16371/44. Divided out of 565,651. Drawings to Specification. [Class 112] The machine is fully described and illustrated in Specification 565,651 and deals with automatic means which are provided to vary the relative feed between the needle and the work to increase or decrease the number of stitches at the eye end of a buttonhole, and quicklyoperable manual means to vary the spacing of the stitches throughout the entire length of a buttonhole. The stitch-forming mechanism and other details are described in Specifications 100,990, 179,278, 183,873, 231,081, [all in Class 112],.and 507,318. The work is held by a workclamp 11 (Fig. 1 of Specification 565,651), of the travelling type, during the entire buttonholing operation, the clamp being rapidly moved over a bed 1, Fig. 3 (Specification 565,651), to carry the work forwardly from the buttonhole cutting position, to stitching position, then more slowly moved step-by-step to place the stitches about the buttonhole and then rapidly restored to initial position. The stitches around the eye of a buttonhole are not crowded but spaced evenly by a third-feeding mechanism which overdrives the slow step-by-step stitching feed, imparting to the feed-cam 10 step-by-step turning impulses of greater amplitude than those imparted by the normal slow-stitching feed. The third-feeding mechanism comprises a member 52 on a gear 20, a clutch-spider 54 formed with recesses 55, each containing a clutch element 57 engaged by a plunger 58 backed by a spring, the plunger forcing the element 57 towards the narrow end of the recess,55. The spider is oscillated continuously during the operation of the stitch-forming devices, by means of a lever 61 connected to a link 63 coupled to a vibratory lever 64 pivoted on a stud 65. The lever 64 is vibrated by an adjustable eccentric 67 on a shaft 44. The stud 65 is on an eccentric and may be moved by a handle 71 to vary the movements of the link 63 and thus the spacing of the stitches. A spring-pressed detent on the handle 71 enters one of a number of holes.

Abstract: 167,348. Schneider, L. J. May 31, 1920. Heating by electricity.-An electric waterheater in which a continuous flow of water is heated by the passage of a current therethrough, has a series of electrodes arranged in alignment the alternate electrodes 18, 19 being connected to the leads 20, 21 respectively of the circuit. The electrodes are contained in a chamber 1 formed of inner and outer metal shells 5, 4 separated by a layer of insulating material. Perforated plates 22 of insulating-material which bear against the sides of the heater support the electrodes and separate them into groups. The electrodes are formed with central apertures arranged in alignment. The main heating-circuit C' is completed through a switch 31 closed by an electromagnet 30 when a circuit C is completed. The circuit C contains a switch S which is closed when water is turned through the heater by the water raising a valve 9 in a chamber 8 against the pressure of a spring 12 and so lifting a pin 14 to bridge the gap between contacts 16. The valve has lateral apertures 10 and also a bypass 11. A thermostat 23 breaks the circuit when the temperature of the water rises too high.
