Title: Improvements relating to electrical computing instruments
IPC: G06G7/16
Filed: 1947-02-27
Abstract: 621,665. Modulating apparatus. FERRANTI, Ltd., and TAYLOR. M. K. Feb. 27, 1947, No. 5665. [Class 40 (v)] [Also in Groups XXXVIII and XXXIX]. A computing instrument for obtaining the product z of two quantities x and y, at least one of which is represented by an alternating current or voltage, is constructed as a dynamometer whose moving coil is attached to a piezoelectric crystal so that the product appears as a strain on the crystal, thereby producing an alternating voltage between two faces of the crystal. In one embodiment, Fig. 1, the moving coil 1 of a dynamometer movement which is capable of limited vibration only, is attached to one end of a piezo-electric crystal 10 responsive to torsion, the other end being held by a clamp 11. The x and y currents of the same frequency are fed to the fixed and moving coils producing an oscillatory mechanical force on coil 1, which in turn supplies an oscillatory torque to the free end of the crystal 10, resulting in a voltage z across its faces which is proportional to the product of x and y. The polarity of the poles 6, 7 of the electromagnet 8 may be such as to produce a twisting effect on the moving coil 1, or may make it vibrate bodily. The moving member may be mechanically adjusted to resonate with the frequency of x and y. If resonance is not required, the instrument may be damped by immersion in oil. In another embodiment, Fig. 3, two electromagnetic systems 20, 20<1> are set up facing each other, with moving coils 29, 29<1> attached to a crystal 21 so that the crystal is subjected to an alternating compressive stress or tensile stress or alternate tensile and compressive stress. When x and y quantities are both alternating currents or voltages, the A.C. output z is independent of any phase difference between them. The instrument may be used as a modulator.

Title: Improvements in machines for making seamless tubing of metal, pulp or other material
IPC: B21C25/04
Filed: 1919-03-11
Abstract: 137,672. Neuberth, G. E. March 11, 1919. Squirting.-An extrusion press for forming seamless tubes is formed with a slightly tapered core which is adapted to facilitate the extrusion process. Means are provided for centring this core, which may be formed with more than one degree of taper. As shown, a hollow metal billet L is extruded from a cylinder A by means of an hydraulic ram B, preferably provided with a dummy block or ring K of hard heat-resisting steel or other material, and formed at its forward end with a recess R adapted to form a guide for a conical head F fitted to the steel or other core C, which is tapered and acts in conjunction with a die G to shape the tube being formed. At the commencement of the extrusion process, metal is forced into the space between the rounded end of the recess in the block K and the core C, and as this becomes cool and sets, it retards the forward motion of the core C, and increases the length of tube which can be formed by the press. At the end of the operation, the end of the formed tube is cut by the action of the head F and the die G.

Title: Improvements in or relating to screwthread gauging devices
IPC: G01B3/40
Filed: 1951-03-16
Abstract: 711,540. Gauging screw-threads. WILLS, S. A., GATHERCOLE, E. F. J., and TOLIMIT GAUGES, Ltd. March 4, 1952 [March 16, 1951], No. 6402/51. Class 106 (2) A screw-thread gauge has at least two gauging members and at least one of these is in the form of a rotatable roller having a circumferential rib affording a thread formation for engaging the screw-thread to be gauged and each roller has in it at least two circumferentially spaced holes and there is a locating member arranged selectively to engage these holes in order to locate the roller positively in any one of two or more predetermined rotational positions. The invention is shown applied to the gauge described in Specification 711,541. For holding each of the "go" gauging rollers 14 against rotation a locating needle 22 is provided which passes through any one of three holes 23, 23A and 23B circumferentially spaced around the roller midway along its length. The tip of the needle enters a bore 24 in the pin 18. To allow for endwise adjustment of the rollers 14 each pin 18 has a longitudinal slot 25, Fig. 3, and each needle 22 is supported in the body 10 by a screw formation 26 at its outer end so that it is sufficiently flexible to permit limited movement of the other end. The wide portions 16 of the rollers 14 are provided with three longitudinal cut away parts each having one radial surface 27 and one approximately tangential surface 28. The holes 23, 23A, 23B enable any one of the radial surfaces 27 to be located in the plane containing the centre lines of the rollers 14. The surfaces 27 afford scraping edges for removing dirt from the article to be gauged while, where the surfaces 28 cut the thread formation 15 of the rollers they form a lead to facilitate the insertion of the article. There are three distinct gauging portions on each roller 14 which may be arranged, e.g. for gauging articles having the same thread formation but allowing for different tolerances or the three portions may be identical and used successively as they become worn or the three portions may have different thread formations for gauging different characteristics of the same screw-thread. If the end faces of the rollers are machined strictly at right angles to the axis of the rollers endwise adjustment will be unnecessary when new gauging portions are brought into operation. The term roller as used includes any member having one or more arcuate surface portions of generally cylindrical form about an axis and with a thread formation thereon, irrespective of the angle subtended at the axis by the arcuate surface or surfaces.
