Title: Improvements in automatic measuring systems
IPC: G01R17/04
Filed: 1942-05-13
Abstract: 556,134. Automatic control systems. KEINATH, G. May 13, 1942, No. 6512. Convention date, March 21, 1941. [Class 38 (iv)] [Also in Groups XXXVIII, XXXVI and XL] In a system in which an indicating or controlling effect is brought about by balancing a voltage or force produced at the transmitter by a voltage or force varied at the receiver, the latter voltage or force is varied continuously, an effect being produced at the moment of balance. In all the arrangements described a condenser is charged during the out-of-balance period and discharged at the instant of balance to produce the desired effect. In a system, Fig. 6, for keeping a furnace at a predetermined temperature, the voltage of a sensitive element 521 in the furnace is periodically balanced by a potentiometer 545. A wiper arm 511 driven synchronously with the potentiometer co-operates with a manually or automatically adjustable gapped ring, the arrangement being such that unless the point of balance occurs when the wiper is in the gap, a discharge from condenser 116 occurs through a coil 561 or 562 to cause the heat supplied to the furnace to be increased or decreased. Specification 193,841, [Class 37], is referred to.

Filed: 1973-02-09
Abstract: 1431861 Controlling nuclear reactors UNITED KINGDOM ATOMIC ENERGY AUTHORITY 16 Jan 1974 [9 Feb 1973] 6579/73 Heading G6C A nuclear reactor, e.g. a high-temperature gas-cooled reactor with downflow cooling, embodies a control system including a flexible or filamentary neutron-absorbing member 8 which, when lowered with the core 2, piles up against stop means so as to increase its neutronabsorbing effect on the reaction. As shown (Fig. 1) the chain 8, e.g. of boron steel, piles up within core channel 10 thereby simulating a bottom-entry control rod. The channel is cooled by gas throughflow from upper plenum 5 to lower plenum 6. Links of chain 8 may comprise boron powder-filled metal tubes bent to shape. As an alternative to a chain, the member may comprise articulated plates, or bodies threaded on a cable.  Means for lowering and raising the member 8 comprise (Fig. 3) a stepping motor 25 which drives a wheel 9 and a storage drum 22. A weight 23 compresses a spring 34 when the member 8 is fully raised, as shown; the weight and spring provide forces additional to those provided by member 8 with its end-weight 21, for accelerating the member 8 into the core for rapid shut-down when control of motor 25 is removed. Weight 23 is stopped by shockabsorber 40 and member 8 is stopped by, and piles up against, shock-absorber 11.

Abstract: 764,729. Television. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 7, 1955 [March 10, 1954], No. 6624/55. Class 40 (3). A colour television picture reproducing unit comprises three projection units 13, 14, 15 (Fig. 2) individually associated with respective component colours and each comprised (as shown in Fig. 2) of an arrangement of projection tube 1, spherical mirror 6, plane mirror 7 and correction plate 9. The units are positioned with the axis of the tubes parallel to each other and the tube screen ends facing the same direction, a beam splitter consisting of dichroic elements 25, 26 arranged at an angle of 90 degrees to one another and having the common edge l parallel to the axes of the tubes acting as a colour selective image combining means for producing a composite colour image on a projection screen 27. An advantage of this arrangement is that variations in brightness of each component image due to the fact that the plane mirrors 7 are at an angle with the axis of the associated cathode-ray tube are distributed over the whole of screen 27 in identical manner. By arranging the projection units 32, 33, 34 and the associated dichroic elements 30, 31 as shown in Fig. 3, a more compact arrangement is realized. Fig. 4 shows a further arrangement of the projection units (comprising the tubes 38, 39, 40, spherical mirrors 41, 42, 42, plane mirrors 45, 46, 47 and correction plates 35, 36, 37) and the dichroic elements 30, 31 also resulting in a compact arrangement.

Title: Improvements in or relating to textile throwing machines
IPC: B65H59/06
Filed: 1955-03-08
Abstract: 774,827. Devices for controlling unwinding yarn. RATTI, M. March 8, 1955 [March 24, 1954], No. 6720/55. Class 120 (2). A device adapted for mounting upon an unwinding spindle of a textile throwing machine and to prevent snarling of the threads unwinding from said spindle when the machine is stopped comprises two substantially annular shells, one of which is provided with a tubular extension adapted to receive the other shell in such a way as to leave a narrow opening therebetween, a generally annular block mounted upon said tubular extension and carrying a spring, one end of which is secured in said block and the other end is free and constitutes a projection which in the rest or stop position on the spindle extends outwardly from the opening between the two shells to exert on the thread a tension sufficient to prevent it from snarling, while during the rotation of the spindle, it is centrifugally retracted into the interior of the two shells so that it does not touch the thread. In the arrangement shown a device according to the invention is mounted on the end of a spindle V and includes two shells 1 and 2 the first of which has a tubular extension 4 over which the second is slipped and held in the desired position by a clip 3 such that a space 9 remains between the shells 1 and 2. A small block 5 is mounted loosely, but subject to friction due to contact with the shells 1 and 2, on the tubular extension 4 and carries a spring 6 one end of which is engaged in the hole 7 in the block 5 whilst its other end forms a long projection 8 which in the position of rest of the spindle extends outwardly from the opening 9 to contact the thread. When the spindle V reaches its rated speed centrifugal force acting on the spring 6 overcomes the action of the spring and moves it generally radially outwards so as to cause the projection 8 to retract into the opening 9 thus leaving the thread F free to unwind. Conversely when the spindle stops the projection 8 moves outwards under the action of the spring to contact the thread and prevent it snarling.

Abstract: 382,518. R÷ntgen-ray apparatus. MœLLER AKT.-GES. C. H. F., 24, Rontgenstrasse, Hamburg, Germany. March 7, 1932, No. 6802. Convention date, March 11, 1931. [Class 98 (i).] A device for X-ray examination of small quantities of material, especially a liquid or powder, comprises a hollow metal body which is attachable, as by a screw thread, to a mounting formed round the window portion of an X-ray tube, and which serves to receive a container enclosing the material. The body may house, at the end remote from the ray tube, a ray-measuring device such as an ionization chamber. It is stated that the device may be used for determining the ash content of various kinds of coal. As shown in Fig. 1, a ray tube 1 has a metal middle portion 2 which is fixed by a clasp 3 to a stand, and which has a screwed flange 5 round the emission window adapted to receive the screwed end of a tubular metal casing 6 having a hinged door 7 through which a container 9 enclosing the material to be examined may be inserted. An apertured chamber 10 at the end of the casing remote from the tube 1 serves to house the raymeasuring device. The casing 6 consists preferably of a metal having a high atomic weight so that it is impervious to X-rays. The container 9 consists of paper, celluloid or other ray-pervious material, and may be graduated. In a modification, the door 7 is not provided, and the casing 6 must be screwed off the ray tube for loading. In this form the container 9 is introduced through a window 18, Fig. 3. into an open-ended metal tube 16 which is loaded into the casing 6 through its upper end.

Title: Improvements in the treatment of filamentary textile materials
Inventor: GREENWOOD ERNEST LESLIE
IPC: D06B1/12
Filed: 1932-03-07
Abstract: Liquid is applied to travelling artificial filamentary material continuously with its production by a wick through which the liquid is flowing continuously past the point of contact of the yarn with the wick.  Such filamentary material includes yarns, threads, straws, tapes, bristles and like materials, the liquid including dyes, sizes, conditioning and solvent liquide and may, if a solvent, contain a small percentage, e.g. 0.1 per cent of the substances of which the filaments consist.  The continuous flow of liquid through the wick may be created by siphon action, or the liquid may drip steadily on to the wick.  The wick may be arranged as in Specification 366,585. The applied liquid may be used once only, or be circulated repeatedly through the wick, with, if desired, adjustment of composition of the liquid replacing that taken up by the yarn to allow for the constituents taken up by the yarn.  The filamentary materials may be yarns or staple fibres of reconstituted cellulose, or cellulose derivatives.  As shown in Fig. 1, a number of threads 4 are drawn from bobbins 5 through a spacing reed 7 and over and under rods 8 to form a ribbon, which is passed over a device 10 which applies a solvent.  By passage round knife edges 11, 12 and roller 13 and through nipping rollers 15 the softened filaments unite to form a flattened ribbon.  The <PICT:0398191/IV/1> <PICT:0398191/IV/2> device 10, Fig. 2, contains a wick 19 dipping into a reservoir 20 with an overflow hole 22.  The wick hangs over an extension 23 of the reservoir wall, liquid thus siphoning from 20 into 24 from which it is drawn off at intervals.  The cover 27 and dome 28 minimize loss of solvent material by evaporation.

Filed: 1929-03-04
Abstract: 307,746. Compagnie Francaise d'Exploitation des ProcÚdÚs. Plinatus, (Assignees of Plinatus. W.). March 12, 1928, [Convention date]. Mother of pearl, artificial.-An iridescent sheen is imparted to a mass of casein, by subjecting it to stress while in a cold or lukewarm state and then heating under pressure, and maintaining the stress while setting by cooling under pressure. The stress may be produced by an extrusion press, or by passing the material between rollers mixing at different speeds or merely by pressure. Freshly prepared masses, and hard masses show the effect most strongly. Variegated effects may be produced by mixing masses of different hardness, colour, &c., or by the addition of crystals, bronzes. The sheen is not destroyed by treatment with hardening substances such as aldehydes and ketones or their dihalogen or thio compounds.
