Title: Improvements in and relating to the wearing surfaces of heels of boots and shoes and the like
IPC: A43B21/39
Filed: 1930-02-13
Abstract: 348,683. Boot &c. protectors. BRISCOE, A., 130, Eighth Avenue, Bezuidenhout Valley, Johannesburg, South Africa. Feb. 13, 1930, Nos. 4841 and 6447. [Class 17 (iii).] A renewable wearing pad or heel lift 3, Fig. 8, for a boot &c. is formed with a groove 25 of complementary shape to a projecting plate or piece 22, preferably of metal with straight, rearwardly-converging undercut, dovetail, or rebated edges fixed to the underside of the heel 2, Fig. 9, of the shoe, whereby it may be attached by a forward sliding movement. Means, such as a screw engaging registering holes 13 in the pad 3 and heel 2, a spring-pressed bolt in the heel 2 engaging a recess in the pad 3, or an L-shaped nail fitting in a recess in the pad 3, are provided to lock the parts together. The plate 22 may be in two pieces with a dovetail groove between the two parts, if desired. Specification 9282/11, [Class 17 (iii), Boots and shoes, Protectors &c. for], is referred to.

Title: Improvements in or relating to instruments for measuring and indicating variables
IPC: G01R1/30
Filed: 1943-03-26
Abstract: 568,676. Meters; indicating-apparatus. FOSTER INSTRUMENT CO., Ltd., and FOSTER, C. E. March 26, 1943, No. 4926. [Class 106 (iv)] [Also in Group XXXVI] The invention relates to instruments of the type in which an unknown variable to be measured is opposed to a known variable, adjustable at will, a scale being positioned according to the value of the known variable, and a pointer according to the degree of out-of-balance of said two variables, whereby the relative positions of said pointer and scale indicates the value of the unknown variable. In Fig. 1, the potential developed by a pyrometer 1 is opposed by a potentiometer 3, secured to a scale 9, rotatable by rack-and-pinion mechanism, Fig. 4, to vary the value of the potentiometer resistance tapped off by a fixed slide 5. If the potentials of the pyrometer and the potentiometer are balanced or nearly so, the needle 7 of a galvanometer comes within a beam of light projected through an opening on to a screen to indicate on the magnified image of part of the movable scale 9 the temperature corresponding to the potential developed by the pyrometer. The plate 14 may carry stops for the needle 7 with coloured patches adjacent the stops to indicate the limits between which the needle must lie for accurate indications. The invention is also applicable to the measurement of resistance (Fig. 2, not shown) employing a ratiometer, or (Fig. 3, not shown) employing a Wheatstone bridge.

Title: Improvements in or relating to Power Transmission Mechanism.
IPC: B24B47/04
Filed: 1919-02-27
Abstract: 124,198. Norton Grinding Co., (Assignees of Alden, G. I.). March 22, 1918, [Convention date]. Reversing-gearing.-To avoid shocks in the reversing of a heavy member driven by worm- and-wheel gearing, such as the table of a grinding-machine or a lathe, the worm is movable axially on its shaft to enable the parts to come to rest slowly and gradually to gain speed. The worm 6 is movable axially on a shaft 3 driven in two directions under the control of a reversing- clutch 2, connecting it to a driving-shaft 1. The worm has a projection 20 engaging a. slot in a sleeve 9 loosely keyed to the shaft 3, and also a roller 23 working in a cam slot 24 in a sleeve 22, which is formed with friction surfaces 42, 43 engaging fixed friction surfaces 40, 41 under the thrust of the worm to act as a light brake, preventing the sleeve 22 from rotating when the roller 23 is moving in the slot 24. The clutch 2 is keyed to the shaft 3 with a considerable quantity of lost motion, as shown in Fig. 3, and during the period represented by this, in reversing, the parts slowly come to rest under friction. When the reverse drive is taken up, the roller 23 moves from one end to the other of the slot 24, moving the worm axially so that the worm-wheel 7 gains full speed gradually. To prevent the premature movement of the roller 23 along the slot 24 while the parts are coming to rest, the sleeve 22 is temporarily locked by springs 71, 72, Fig. 6, en. gaging grooves 77, 78 and operated by a finger 70 on the shaft 3 permitted to act by the lost motion between the key 16 and its groove 19 by which the sleeve 9 is secured to the shaft 3. The relative motion between the sleeves 9, 22 allowed by the springs corresponds to the lost motion in the clutch 2 as shown in Fig. 3. In a modification, the end thrust of the shaft 3 is taken by a ball bearing and the friction brake surfaces are replaced by a light band brake. Specification 105,973 is referred to.

Abstract: 491,020. Image dissectors. FERNSEH AKT.-GES. Feb. 24, 1937, No. 5562. Convention date, Feb. 24, 1936. [Class 39 (i)] The electron image is focused upon one or more plane secondary emitting electrodes before being focused in the plane of the apertured scanning electrode, and electrons passing through the aperture are electrostatically or electromagnetically deflected before being incident on the collecting electrode. The secondary emitting electrodes may be permeable and may be connected to wall coatings on the cylindrical envelope, and a focusing solenoid round the tube may be employed. As shown, electrons passing through the aperture 13 are deflected by an electrode 15, and the low velocity electrons from the last secondary electrode pass through a second aperture and fall upon the collector 14. The high velocity electrons which have missed multiplication at the last secondary electrode miss the second aperture. The secondary electrodes may be of mesh, foil or solid sheet and a magnetic field may separate the primary and secondary streams. The electron image may be enlarged or reduced.

Title: An improved process and apparatus for drying artificial silk in the form of cakes orloose packs or bundles
IPC: D01D10/04
Filed: 1931-02-23
Abstract: <PICT:0358847/IV/1> Artificial silk in the form of cakes, loose packs, or bundles is dried in such manner that the drying medium is led practically exclusively along the freely exposed inner walls of the middle apertures of the cakes, packs, or bundles.  As shown in the drawing a vertical drying duct 1 is provided on the bottom 2 with a number of openings 4 over which a number of cakes are arranged side by side with their central openings 5 exactly over the openings 4. The cakes are covered with a plate or container 6 provided with apertures corresponding to the openings 4.  Another layer of cakes is placed on the plate 6.  The cakes are thus built up into a number of columns with intervening plates between the superposed cakes.  The plates 6 may be removably secured to the wall of the duct 1.  Warm air is passed through the duct in either direction.  The process may be carried out continuously by providing the containers or plates 6 with chains or endless transport belts which are continuously passed through the duct 1. By adjustment of the temperature and velocity of the drying air, and the velocity of the plates carrying the cakes, the latter may be made to emerge from the duct in the dry state.  The cakes treated in this manner are dried from the inside outwardly so that the various layers of threads may shrink freely, and that after drying there are no differences in shrinkage between the inner and outer surfaces of the cakes.

Filed: 1924-03-06
Abstract: 227,013. Wildt & Co., Ltd., and Wildt, E. March 6, 1924. Winding-machines.-Relates to machines of the vertical spindle type for winding yarn upon conical or bottle bobbins and wherein the guide is traversed and fed upwards on its support to build the bobbin in a succession of conical layers. The disc 1, which is connected by a nut device 11 to the screwed rod 3 and controls the feed of the yarn guide, is operated by ratchet gearing 13, 14 during the fall of the reciprocating traverse bar 5 so that the guide is raised a distance slightly less than that necessary for the finest yam, and is further operated by contact with the yarn on the bobbin to complete the necessary movement of the guide corresponding to the thickness of the yarn. A lever 4 mounted on the bar 5 carries the disc 1 and the ratchet wheel 13, and is oscillated by a cam 7 so that movement is imparted to the wheel 13 by the pawl 14, which is carried by an arm 15 pivoted about the axis of the disc 1 and engaged by a stationary adjustable rod 16. The yarn guide 20 is carried by a wire or like finger 19 mounted on a collar, 18 fast on the pivot of the pawl, so that the tension of the yarn normally maintains the pawl in contact with the ratchet wheel, but upon breakage or running out the pawl runs idly. A pawl 22 prevents backward movement of the ratchet wheel. The disc 1 and the ratchet mechanism may be mounted on the traverse bar, and the pawl arm be operated by a rod on an oscillating lever or by an inclined rod.
