Title: Improvements relating to the production of artificial silk
IPC: D01D5/06
Filed: 1930-12-15
Abstract: <PICT:0363505/IV/1> <PICT:0363505/IV/2> In the wet spinning of artificial silk each thread is passed through a trough arranged in the spinning bath over a part of its travel through the bath so that any individual filaments which become loosened are carried back to their own thread.  Where a number of threads are passed through the same spinning bath, the arrangement of the trough prevents filaments of different threads from becoming entangled with one another.  The trough is preferably perforated and carried on the same member which supports the thread guide.  It may be pivotally mounted so that it may be turned to suit the new direction of the thread when the thread guide is displaced in order to alter the length of thread in the bath.  As shown in the drawings, the precipitating liquid is contained in a bath 1 and the spinning nozzles 2 are placed so that the threads 3 pass obliquely across the bath, around the respective thread guides, and then to winding devices.  The thread guides 4 are supported on holders 5 which can slide along a cross-bar 6 which may be moved to alter the length of thread in the bath.  Troughs 7 of channelled section are carried from the same holders 5 which support the thread guides 4, and are pivotally mounted at 8.  The side walls of the troughs 7 are perforated to give the precipitating liquid ready access to the threads 3.  One or both sides of the troughs may project above the surface of the liquid.  The troughs may be made of lead or aluminium with or without a varnish coating, ebonite, rubber-coated metal, or artificial resin.

Title: Apparatus for and method of determining rotational or linear stiffness
IPC: B25B23/14
Filed: 1975-09-19
Abstract: 1526948 Torque control of wrenches STANDARD PRESSED STEEL CO 19 Sept 1975 [19 Sept 1974] 38575/75 Heading G1N [Also in Divisions B3 and G3]  Apparatus for measuring the stiffness of a bolt comprises means for determining the gradient of the torque/angle of rotation relationship, and is used to stop the tightening of the bolt when the gradient falls to half the maximum gradient, indicating that the bolt is approaching its yield point. In one embodiment, Fig. 2, a bolt is rotated by a tool 2 driven by a motor 10 through a spring coupling 11. The torque is measured by the difference between the rotation ° 1  at the input end, measured by a first toothed wheel encoder 9, and the rotation ° 2  at the output end, measured by a second toothed wheel encoder 6. The angular difference is continuously determined in a comparator 22, Fig. 3, where it is divided by ° 2  to obtain the torque curve gradient. The maximum value is stored at 24 and compared at 23 with the instantaneous gradient. When the latter falls to half the former a signal is produced to stop the motor 10. The output from the motor may be converted to a linear movement to determine the yield point of tensile samples.  In another embodiment, Fig. 7, a wrench 50 comprises a driver bit 59 coupled to a motor 52 by a flexible part 64 carrying strain gauges 72 which measure the instantaneous torque. The angular rotation is measured by a pick-up 74 associated with a toothed member on the shaft, or the vanes 76 of the air motor 52. The rotation signals are used to sample the torque at equal intervals, the difference being determined at 94 and representing the torque/rotation gradient. The maximum value of the gradient signal is stored at 102 and a pre-set proportion, e.g. half, determined at 106 for comparison at 98 with the instantaneous gradient signal. When the former exceeds the latter the motor 52 is stopped.

Abstract: 859,956. Spark producing apparatus. NAPIER & SON Ltd., D. Dec. 10, 1958 [Dec. 12, 1957], No. 38686/57. Class 7(4). Spark producing apparatus comprises a main condenser, a charging system for the main condenser and means for simultaneously connecting the main condenser when charged to at least two parallel connected branches which are inductively isolated from one another and each of which includes a sparking plug and each of the branches has capacitance and inductance which form a low-loss time delay circuit connected to the plug and the delay period of which is approximately the same as the time required to ionise the slowest of the various plugs which are connected to the spark generator. In Fig. 1 a condenser 17 is charged by way of a rectifier 16. The condenser is associated by way of a spark gap 18 with an external circuit 20. The circuit 20 comprises a number of parallel connected branches each containing a lead 21 to a sparking plug. In Fig. 2 the inductances 24 and the condensers 25 are in parallel with one another. Other arrangements of the parts are disclosed in the Specification. Circuit component valves are quoted. Suitable materials for the core are those commonly used in high frequency circuits where high permeability and low eddy current loss are important for instance compressed powdered iron or a magnetic ferrite such as "Ferroxcube". Circuits using auto transformers may be tuned to resonance by the addition of extra capacitance for instance by connecting an additional condenser in parallel with the plug. If shielded plug leads are used their natural capacity may in some cases provide sufficient additional capacitance to replace some of the condensers. Open gap plugs may be employed as well as surface leakage plugs. Suitable existing systems can be modified by means of an adapter.
