Title: Improvements in or relating to the manufacture of artificial textile fibres
IPC: D01F9/04
Filed: 1940-11-14
Abstract: 545,872. Beryllium alginate. SPEAKMAN, J. B., CHAMBERLAIN, N. H., and CEFOIL, Ltd. Nov. 14, 1940, No. 16503. [Class 1 (iii)] [Also in Groups IV and VIII] In the production of alkali-resistant alginate fibres, filaments, yarns or films, the alginate is converted partly or completely into beryllium alginate. In an example, a solution of basic beryllium acetate is obtained by suspending beryllium carbonate in water, mixing the suspen. sion with glacial acetic acid, warming on a steam bath till the carbonate is dissolved and most of the carbon dioxide expelled, cooling and diluting with a large quantity'of water. Yarns of calcium alginate are steeped in a dilute solution of the basic beryllium acetate at room temperature for two days. The yarns and liquor are then heated on a boiling water-bath for an hour and the yarns are then removed, washed, and dried. The yarns may originally be composed of calcium, aluminium or other alginate, or of alginic acid. They may be treated so that they consist of a mixed aluminium, chromium, and beryllium alginate by steeping in a solution containing aluminium triacetate, chromium acetate partly in the form of a basic salt, and basic beryllium acetate. In another example, a solution of sodium alginate is extruded into a solution of beryllium sulphate in water acidified with hydrochloric acid. Beryllium alginate fibres are obtained directly. Specification 541,847, [Group IV], is referred to.

Filed: 1953-06-16
Abstract: 739,011. Statistical apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 16, 1953, No. 16547/53. Class 106 (1). A control device for a record card controlled machine comprises a plurality of elements each containing a first relay operable on receipt of impulses from preselected parts of the machine, or the device, to prepare a circuit for operating a second relay, means for energizing the operating circuit periodically, and means for connecting contacts of the second relay so that preselected machine functions may be initiated therethrough. Fig. 1 shows the normal D.C. supply of a known machine represented by lines 1 and 2. The control device is made up of a plurality of elements each of which includes two relays. The first relays 11-16 are latch relays with release coils 21-26, 31-36 are the corresponding second relays of the several elements. When it is desired to control any of the units of the cycle count the appropriate hub c is connected to a hub emitting impulses, e.g. a reading brush, the corresponding relay, for example 12, picks up, and its armature remains latched until coil 22 is energized. When cam C1 contacts make, coil 22 is energized and the relay 12 is unlatched and contacts 12a, 12b, 12c return to their normal position. When the contacts of cam C5 make, emitting hubs J2 are energized through the closed contacts 32c-#. These hubs may cause energization of a selector, transfer from one counter to another or printing of results registered in a counter. If desired, a single impulse may initiate successive operation of several elements, or alternatively it is possible to control every element separately. In certain cases it may be required to control the functions assigned to several separate elements at the same time. For this, hubs B are connected together. For example, if elements 2 and 4 are to be controlled together hubs B2, B4 are connected. When contact C4 is made, relays 32 and 34 are energized in parallel through circuit C4, contact 11c, contact 12c, contact 39b, relay 32, line 2, contact 12b, hub B2, hub B4, contact 14b, contact 39d, relay 34, line 2.

Abstract: 219,324. Matthey, C. July 19, 1923, [Convention date]. Dynamos, driving and regulating.-In a portable lamp in which a spring-driven generator is employed, the driving spring is of coil form working by torsion about the axis of the coil and is housed between two coaxial tubes which enclose the generator and at least part of the driving members therefor. In the form shown, the generator 11 and driving-train 8 are contained in an inner tube 3 between which and an outer tube 2 is the spring 1. The spring is attached at its upper end to a ring 4 and at its lower end to an annular gear wheel 5 positioned between the tubes 2, 3 and retained by a cap 7 to which is secured an outer sleeve 14. A screw 15 in the plate 7 enables the train to be locked and a ratchet and pawl 16 on the lamp member 13 and ring 4 allow relative rotation between the tubes 2, 3 in one direction only for winding. To wind the spring without lighting the lamp, the train is locked by means of the screw 15 and the member 14 turned with respect to the tube 2, carrying with it the train, generator 10, 11, lamp member 13, wheel 5 and the lower end of the spring until the spring is tightly coiled against the tube 3. On release of the screw 15, the spring rotates the wheel 5 and drives the armature through the train. The unwinding of the spring is checked by its abutment on the tube 2 and as it is so arranged as still to be stressed when it lies against the tube, the dynamo speed is practically constant throughout the unwinding. The spring may be wound while the lamp is alight as its speed of winding is greater than its running-down speed. The cap 14 may be replaced by a key or other member and a reduction gear may be inserted between this member and the inner tube to facilitate winding. Also, the spring may be alternatively arranged so that it bears against the outer and inner tubes respectively when wound up and unwound. For regulating the dynamo, a flux shunt may be employed, this being governed by the variation in the diameter of the spring during unwinding.
