Title: Improvements in the manufacture of fabrics on twist-lace machines
IPC: D04C1/00
Filed: 1919-03-26
Abstract: 140,210. Cutts, J. March 26, 1919. Lace.-Bands of cloth fabric are made of any desired width, with fast selvedges, either plain or ornamented and with or without an ornamental design, one class of threads, e.g. tinsel silk or artificial silk, being all disposed at the front to form the face of the fabric, while the remainder, situated at the back, form the foundation. When tinsel threads are used, a gold or silver faced fabric is obtained. In the preferred set-out, a reverse twist thread B, a weaving-thread C, and three facing-threads D are employed in connexion with each bobbin thread A, but other numbers of weaving and facing threads can be used, and the reverse twist thread may be omitted. In a twelve-motion repeat fabric, the foundation threads are disposed, as indicated in Fig. 1. The threads B twist with the same bobbin threads A throughout. Each weaving-thread C is moved over four or other number of bobbin threads A and twists with each in succession and returns. Fig. 2 shows the facing-threads D, the first and second sets being secured to the foundation by the bobbin threads A on the first and seventh motions respectively, while the third set is secured on the fifth and eleventh motions. The procedure can be modified to admit of two weaving or two facing threads being used to each bobbin. In a ten or eight motion fabric made with two facing-threads D to each bobbin, the weaving- threads C are moved over three bobbins instead of four. A double-faced fabric is obtained by employing facing-threads D at both front and back.

Title: Improvements in and relating to means for indicating, recording or registering the content of a substance present in a liquid
IPC: G01N21/78
Filed: 1939-03-15
Abstract: 517,462. Photo-electric testing apparatus. HOLGATE, J. March 15, 1939, No. 8050/38. [Class 40 (iii)] The content of a substance present in a Jiquid, such as the content of chlorine in water, is measured by causing predetermined quantities of the liquid to be introduced successively into an inspection chamber f, Fig. 1, causing each quantity in passing to said chamber to absorb or take up by suction from a source of constant head a determined quantity of a reagent which in proportion to the content of the substance gives to the liquid a corresponding depth of colour or transparency, traversing the inspection chamber by rays falling on a photo-electric cell or like sensitive element, and indicating, recording or registering the variations of current caused in the cell and representing the proportion of the substance in the liquid. As shown, the liquid, e.g. water, comes from a pipe a to a tank b having an overflow pipe b<1> leading to a tank c with a drain pipe c<1>. From tank b the liquid passes through regulating cock d<1> and pipe d to tank e, from which predetermined quantities are successively passed to the inspection chamber f by a syphon g. An overflow pipe e<1> leads from tank e to tank c. The reagent e.g. orthotoluidine is stored in a closed-tank h and passes therefrom through regulating cock h<4> and pipe h<3> to tank i, the two tanks being also connected by a pipe which determines the level of reagent in the tank i. Each time a quantity of liquid is syphoned from tank e, it sucks a given quantity of reagent through pipe i<1> from tank i, and level in said tank falling below bottom of pipe allows reagent to flow from tank h until level in tank i is restored. The inspection chamber f, as shown in Fig. 2, comprises baffles #2 providing a circuitous passage giving time for the reaction of the reagent between the pipe g and transparent windows f<1> through which the rays are passed. The chamber is also provided with an outlet #<3>, #<4>, #<5>, and with cleaning plugs #<6>. As shown in Fig. 5, the cell l is fed from a battery m through a resistance n and is connected by a resistance o to grid p<1> of a valve p, the cathode p<2> of which is connected to a tapping m<1> of the battery. The cathode is heated by a battery p<3>, and the circuit of the anode p<4> includes battery q<4> and measuring instrument r.

Filed: 1941-06-30
Abstract: 550,779. Repeating compass readings. BENDIX AVIATION CORPORATION. June 30, 1941, No. 8233. Convention date, June 29, 1940. [Class 40 (i)] [Also in Group XXXVI] The readings of a magnetic compass or other navigational instrument are represented by a radial trace on the screen of a cathode ray tube by the use of a pick-up device of the kind described in Specification 549,528, which comprises as shown a four-limbed core 30 of permeable material having saturating windings 32 fed with A.C. and output windings 34 connected in pairs by way of two transformers 38, 39 to the deflecting plates 48, 49 of the cathode ray tube 50. A compass magnet 29 is mounted above the pick-up, and the voltages induced in the windings 34 deflect the beam along a radial line 60, 61 dependent upon the angular position of the magnet in relation to the pick-up. On account of the alternate saturation and desaturation of the core, the deflection of the beam is greater on one side of the centre than on the other and hence an ambiguity of 180 degrees is eliminated. In a modification, the windings 34 are connected to pairs of external deflecting coils 72, 73 and 74, 75, and the cathode ray tube is operated through a phase-adjusting network 80 and a tapped transformer 82 from the A.C. source 33 that supplies the saturating windings 32. The deflecting coils are carried by a yoke member 96 which may be rotated by a knob 93 to bring the trace along lubber lines 104, 105, an angular scale 89 being rotated at the same time. Instead of employing the compass magnet 29, the pick-up may be mounted as in Specification 549,528 to act as an earth inductor. Specification 550,399 also is referred to.

[Class 40 (v)] [Also in Group XXXIX] The signal receiver described in the parent Specification is modified to improve its response to modulated or interrupted signal currents e.g. 1000 Î 17 c.p.s. by tuning to the interruption frequency the anode inductance which sets up an effective operating voltage when a signal with a steep wave front is received. One arrangement, Fig. 1 (not shown) is identical with the corresponding Figure of the parent Specification except that the inductance is tuned. In another arrangement as shown, the rectifier 15 which operates relay SR1 in response to a voltage surge due to inductance L2 tuned by condenser C2, is poled so that anode current passing through the relay is determined solely by resistance 16. The relay is made sluggish by rectifier 17. The pulses applied to the valve may be positive or negative. Resistance R2 may be set so that the circuit responds only if the modulation is sufficiently deep thus providing a further discrimination between signals and fortuitous voltages.

Abstract: 604,676. Reciprocating motors ; electromagnets. CRAMER, S. S. April 5, 1945, No. 8439. Convention date, March 28, 1944. [Class 35] An electromagnet or oscillating motor with a single winding has an arcuately-shaped armature on a sleeve carried by the shaft to be driven, the sleeve being coupled to the shaft during the working stroke and then released by inertia responsive means. In the form shown, the load shaft 6, e.g. of a rivet-setting machine, has a reduced end 7 carrying a disc 16 from which projects a pin 17 which engages a projection on a plate 19 as soon as the armature 9 begins to move, the armature then being coupled to the shaft 6, since the plate 19 is pivoted on disc 12 on the armature-carrying sleeve 8. When the armature is fully attracted its arm strikes the field structure, but the plate moves a little further, due to its inertia, whereby the pin 17 is disengaged and the armature returned by a spring 13. The shaft 6 may be returned to its initial position by a spring 28. The circuit-breaker may be actuated by the armature of separately e.g. manually. Specification 600,717, and U.S.A.
