Title: Method and device for detecting and locating ores by electromagnetic means
IPC: G01V3/10
Filed: 1925-04-28
Abstract: 251,429. Marks, E. C. R., (Aktiebolaget Elektrisk Malmletning). April 28, 1925. Locating conductors; magnetic tests. -Cores &c. are located by the disturbance they cause to an alternating magnetic field made to penetrate the ground, the ratio between the strength of the field at two points being determined by employing two test coils wound on frames I, II, and connected in opposition. In parallel with these frames is connected a telephone receiver or galvanometer T through an amplifier F. The frame I is placed at one of the points to be examined and its plane is varied until no sound is heard in the telephone T, indicating that the plane of the coil coincides with the direction of the field. The frame is then turned through a right-angle, so that its plane is at right-angles to the field. The frame II is then placed at the second point to be examined, connected in opposition to the frame I, and turned until no sound is given in the telephone T. The strength of the field is calculated from the angle between the plane of the frame II and the direction of the field. Instead of rotating the coil II, a variable inductance L may be connected in parallel or in series with the frame, and adjusted until no indication is given in the telephone. The ratio between the strengths of field at the positions of the two frames may then be calculated.

Patent GB-352100-A (GB)
Title: Improved process for the production of articles from water-insoluble albuminous substances of casein-like character
Filed: 1930-04-09
Abstract: Articles are cut or stamped from unhardened rods, sheets or bars of animal or vegetable casein and then partially hardened by treatment with hardening liquid for a limited time, after which they are superficially dried, softened by the action of dry heat and pressed while in this state to their final form, the hardening being completed during the latter process.  For example, the stamped articles are exposed to the action of formaldehyde as a hardening agent for about a week, then superficially dried by exposure to the air for about 24 hours, after which they are softened by dry heating to about 100 DEG  C.  As the amount of water present in the mixture affects the shrinkage in the final product, a constant water content is necessary to ensure uniformity of the finished article.  In all cases, however, the casein should have a moisture content of about 10 per cent, and the amount of water in any added matter such as dyes should be taken into account.  About 25 per cent of water is added before the mixture is worked up into the sheets, rods or bars.  The composition and strength of the liquid in the hardening bath should also be constant to ensure a standard size of finished article.

Abstract: 542,652. Treating textiles with liquids. LUMSDEN & MACKENZIE, Ltd., and GARRETT, C. July 19, 1940, No. 11931. [Class 15 (ii)] Textile fabrics of cotton, linen, or other vegetable fibres are subjected to a mercerizing treatment by dipping in caustic soda solution of about 54 degrees Twaddell and thereafter pulling back the shrunk fabrics to their original width. They are then impregnated with cellulose ethers or regenerated cellulose, impregnated with caustic alkali of 15-20 degrees Twaddell, stretched, and while in stretched condition treated with caustic alkali of greater than mercerizing strength, i.e. greater than 54 degrees Tw. If desire the mercerizing treatment may be carried out on the yarns before they are formed into fabrics and the fabrics are then subjected to the succeeding steps of the process. Cotton fabric in the grey state may be given a preliminary boil or scour in caustic soda, or sodium carbonate solution. The mercerized fabrics may be impregnated with a dilute solution of a cellulose ether in caustic soda and the cellulose ether is precipitated in the fabrics by treatment with a dilute solution of hydrochloric acid and salt. After the stretching and treatment with the strong solution of alkali the latter is washed out rapidly with boiling water, the fabrics being still in the stretched condition. The treated fabrics show good permanent lustre, pleasing handle, good wearing qualities, and reduced tendency to lint during laundering and in use.

Abstract: 1391905 Security alarm systems ALARM EQUIPMENT SUPPLIES Ltd 18 July 1972 [28 April 1971] 11932/71 Headings G4H and G4N In a security alarm system wherein a transponder A in protected premises (Fig. 1) and a control station transponder B (Fig. 2) exchange signals comprising bursts of pulses in turn along a transmission line, a genuine fault in the transmission line is detected in the transponders by the absence of an incoming signal comprising a predetermined number of bursts of pulses. In A, clock pulses pass via gate G1 to turn on a free-running multivibrator FF1 to cause an oscillator S1 to provide a signal in the form of pulse bursts which are applied to the line via a transformer T1 (a further gate G2 being blocked by the occurrence of an output from G1). Each signal is received via transformer T2 in B and passes via gate G3 to a pump P2 and level detector D2. On detection of the predetermined number of pulse bursts, D2 outputs a signal via gate G5 to clear a delay X3 which would otherwise trigger a line fault indicator LF. If a signal is received from A, then a gate G4 is opened by the termination thereof and by the output from D2; a timer and a multivibrator FF2 cause an oscillator S2 to generate an answer signal which is fed to the line via T2. Since the answer signal is transmitted from B between two signals transmitted from A, gate G2 is enabled and the answer signal passes to a pump P1 and detector D1 to clear a delay X1 and prevent the activation of indicator LF1. An alarm signal in A applied to G1 inhibits the clock so that FF1 and S1 remain turned-on and one long continuous burst of pulses is then transmitted along the line continuously; at B, these pass through G3, the output of D2 remains in its triggered state, and the sustained signal through G5 prevents clearing of an alarm delay X2 so that an alarm is energized.
