Title: Manufacture of threads resembling wool
IPC: D01G99/00
Filed: 1933-11-29
Abstract: 418,263. Artificial wool. WACKER GES. FUR ELEKTROCHEMISCHE INDUSTRIE GES., DR. A., 20, Prinzregentenstrasse, Munich, Germany. Nov. 29, 1933, Nos. 33469 and 33470. Convention dates, Dec. 1, 1932 and Oct. 25, 1933. [Class 120 (iii).] Artificial wool is made by twisting two or more bundles of artificial threads on a ring frame under unequal tensions whereby a looped yarn is obtained, which is then further twisted and the loops fractured. The free ends thus obtained may be caused to curl either by boiling the finished yarn in a solution of a soap, salt or acid, e.g. for ¢-2 hours, or by using for the preliminary loop yarn threads which have been previously moistened, reeled under low draught and dried, and which consequently curl. The loops of the preliminary yarn are conveniently fractured by twisting the yarn in a ring frame having a heavy traveller. The thread bundles used for making the loop yarn may comprise artificial threads of different origins, or some artificial threads and some natural threads. The solution used for spinning the artificial threads may contain a substance which is wholly or in part soluble in water, e.g. glycol, glycerine, or an ester thereof, or triacetin ; there may also be present a pigment, dyestuff, or softening agent. Specification 318,201, [Class 120 (ii)], is referred to.

Title: An improved arrangement or apparatus for use in measuring distances and indicating routes on maps
IPC: G01B3/10
Filed: 1934-11-21
Abstract: 447,288. Maps. McGREGOR, O. E., 9, Holland Road, West Kensington, and GEOGRAPHIA, Ltd., 55, Fleet Street, both in London. Nov. 21, 1934, Nos. 33482/34 and 26477 /35. [Class 146 (ii)] Apparatus for measuring distances and indicating routes upon a map comprises a plurality of guiding abutments fixed to and indicating predetermined places on the map and a flexible ligature extensible from a predetermined starting point on the map, the abutments forming guides for the ligature whereby a desired route can be marked by carrying the ligature under tension into engagement with such of the abutments as are contained in the selected route, means also being provided for indicating the approximate mileage of the route marked by the ligature. A ligature or cord 11 is passed from the back of the map 1 through an aperture 12 at the place from which the route to be traversed commences and a ring attached to the end of the cord is pulled so that the cord is drawn out. Pins 3 are mounted on the map at the main points along the routes and the cord is passed round the pins, the ring being finally passed over the pin situated at the destination. By this means, the cord 11 marks out the desired route and the distance is indicated either by graduations on the cord or by an indicator 4 which is operated by the movement of the cord. The indicator may be of the dial type having one or two hands and in the latter case the two hands are geared together so that one indicates units while the other indicates tens of miles. The cord is in this construction normally wound on a spring drum situated in a casing and in the form shown in Fig. 8 means are provided for maintaining the position of the length of cord from the drum 10 to the opening in the casing constant during unwinding. For this purpose, the drum is mounted on a screw-threaded rod 15 so that as the cord is unwound, the drum travels along the rod in the appropriate direction. Motion is imparted to the hands 7, 8 by a crank arm 16 connected to the spindle of the hand 7 and engaging in an opening 18 in the drum. The re-winding of the cord is effected by a spring 18<a> carried by the spindle of the hand 8. Alternatively, the part of the cord at the rear side of the map may carry a pointer which frictionally engages a slot in the map support and moves over a scale thereon or the pointer may be situated in a loop formed in the cord which is shortened as the cord is drawn out, thus moving the pointer over a scale. A length of elastic or a spring attached to the pointer effects the return movement. The scale may be corrected for the general curvature of the routes and a pair of spring blades or a rubber bush may be used to retard the movement of the cord so that the return is not too rapid. A number of apertures 12 may be provided at given centres of the map so that the cord may be passed through any selected one, the indicator being set to zero where necessary.
