Title: Improvements in or relating to apparatus for operating needles for repairing runs infabrics
IPC: D04B17/04
Filed: 1936-11-03
Abstract: 471,704. Darning. GOSTKOWSKI, B. H. Nov. 3, 1936, No. 29925. Convention date, Nov. 8, 1935. [Class 712] Relates to a machine for repairing runs in fabrics. The crank 3 reciprocates a runrepairing needle sliding in a tube 21, by means of a flexible wire 20 and is driven by a motor 2 through a clutch 10, 11, which is engaged and disengaged by means of an electromagnet 18, substantially simultaneously with the switching on and off of the motor, a spring 36 acting on the cranks so as always and immediately to bring it to rest at the dead centre remote from the end of the tube 21. The electromagnet armature may be arranged to engage or to disengage the clutch when the electromagnet is energized, the spring 19 effecting the opposite movement of the armature. The apparatus may be adjusted to engage and disengage the clutch just before the motor is switched on, and just after it is switched off, respectively; it is possible to arrange that the engagement and disengagement of the clutch shall occur just after and before the switching on and off respectively of the motor. The spring 36 and the end 33 of the sleeve 21 are fastened to opposite ends of a member 32 which can rock about the axis of the disc 4 carrying the crank 3, the other end of the spring being connected to the crank. The crank 3 can be adjusted radially on the disc 4 to vary the amplitude of oscillation of the needle. The end of the wire 20 is secured through a threaded sleeve 41, so as to be adjustable in length, to a member 30, articulated at 31 to the crank 3. A spring 39, compressed by a screw 40, exerts a frictional resistance to the rocking of the member 32 in its bearing 38. When the motor is switched off and the clutch disengaged, the inertia of the needle, wire, and crank being small, the spring 36 immediately arrests the apparatus with the crank at the dead centre remote from the end 33 of the sleeve, so that the initial movement of the needle when restarting will be a forward one, thus minimizing risk of damage to the fabric. The points of fixation 37 of the spring 36, and that of the end 33 of the tube could be fixed points. The length of the wire 21 is adjusted so that when the sleeve 41 is nearest the end 33 there is no bare wire, so minimizing the length exposed to buckling. The needle is preferably that described in Specification 468,178. Working speeds of about 2500 stitches per minute may be obtained.

Title: Improved process for testing the physical properties of individual fibres
IPC: G01N3/16
Filed: 1937-11-02
Abstract: 506,729. Testing physical qualities of fibres. ZELLWOLLE - ARBEITSGEMEINSCHAFT GES. Nov. 2, 1937, No. 30005. Convention date, Nov. 14, 1936. [Class 106 (ii)] For determining the properties of fibrous substances, particularly the curling properties, the individual fibre is connected on the one hand to a balance b having a very fine range of measurement and serving simultaneously as measuring and loading instrument, and on the other hand to a clamping device c, adapted to move longitudinally and transversely relative to the fibre. The fibre to be tested is clamped in the curled state between clips a c. The arm b of the balance is balanced by a counterweight, not shown. An increasing load is applied successively at the balance either by ordinary taring in the case of a micro-analytical balance or by tensioning the spring in the case of a torsion balance, and after each loading the carriage g is moved down by rotating the screw d until the balance arm returns to zero, and then the scale K is read. A microscope is arranged horizontally and laterally of the device and the light passing through is projected on to a screen by means of an optical system, the screen having two scales movable with respect to each other. The boundary lines in the microscopic field are adjusted to engage tangentially with the image of the curled fibre and the distance between them measured. The load imparted and lengthening of fibre may be plotted and after the uncurling point is reached a load-extension curve may be plotted. The angle piece h carrying the clip c is shaped to allow a glass vessel f to be raised and'receive the specimen which may be tested under different conditions, for instance while immersed in a liquid in the vessel. The fineness is determined by cutting out the fibre between the clamps and weighing. After uncurling the fibre may be immersed in water and any swelling measured.

Abstract: 192,793. Schlotter, G. A. Nov. 11, 1921. Current m o t o r s ; combined-flow type working-fluid supply. -Relates to a turbine adapted to be operated by eddy currents set up in a current by the turbine casing. A turbine wheel is arranged inside a casing consisting of a hemi-spherical or similar head portion k and a number of rings r decreasing in diameter and so arranged as to form a number of annular nozzles d which increase in length o towards the tail portions s, wherein the rings r and head piece k form a stream-line body. The outer edge of each ring r has a bulge w increasing towards the tail portion s and the rings themselves are thickened at i. The tail portion and one or more rings may be adjusted longitudinally. The head piece deflects the fluid current and sets up eddies therein which give a suction effect on the nozzles d and cause a current flow therethrough from an opening u shown in the head piece k in Fig. 1. Similarly as shown in Fig. 7, the eddy currents formed by a head piece k<1> set up a suction in annular nozzles d' and cause a current flow from openings u<1> through a turbine wheel n; an annular ring z maintains the eddies in a stable condition. Fig. 8 shows a combination of the two arrangements where a wheel n is operated by a current from an opening u in the head piece and a wheel n' is operated by eddies set up by a part x. The lower half of Fig. 8 shows the wheel n' formed with a double blade ring, the portion n<1>w<1> utilizing the eddies set up by the rear head piece x, and the portion n's' utilizing the suction in the casing by the eddies generated by the front head piece. The two turbines may be coupled together to drive a dynamo m on a common shaft.
