Abstract: 1501803 Monitoring bio-electrical activity SIEMENS AG 2 Feb 1976 [24 April 1975] 04056/76 Heading A5R [Also in Division G1] In a device for measuring the bio-potential of subject, the output of each "measurement" electrode 110 (Fig. 13) is compared with the average output of its immediate neighbouring electrodes, 111, 112, 113 and 114. As shown in Fig. 13, the measurement electrode is fed to one input of a differential amplifier 115. The other input is connected to the "star point" 116 of a resistance network 117, 118, 119 and 120 associated with the "neighbouring" electrodes. The differential amplifier 115's output drives an "ink-jet" recorder. A more complicated system involving 20 electrodes is disclosed (Fig. 14 not shewn) only in this case, there are two amplifying stages. In the first stage, each electrode output is fed to a corresponding differential amplifier which also receives the output of a common electrode.

Abstract: 945,144. Sliding clasp fasteners. NOVI PATENTVERWERTUNGS-G.m.b.H. Feb. 5, 1960 [Feb 21, 1959; March 19, 1959; July 8, 1959 (2)], No. 4194/60. Heading E2S. [Also in Division D1] A method of making lengths of material from which sliding clasp fastener stringers may subsequently be cut, comprises weaving together synthetic thread material and textile thread material, the synthetic thread material forming the coupling elements and having preformed deformations at which the synthetic thread material bends during weaving. Fig. 1 shows a length of material in which the synthetic thread material 3 bends at the deformations 23 to a "regular meander" form so that loops 13 carrying the coupling heads and loops 11 within the width of the length are formed; alternate deformations form the coupling heads, and the loops 11 are alternatively located on opposite sides of the length. The thread material 3 at this edge of the length is passed over a wire or mandrel (not shown) and the spacing of the loops between the sides is determined by a cord 2. A textile weft thread 18 and textile warp threads are also used to form the length. The warp threads 16, 17 connect the loops 11 on one side of the length and the warp threads 19, 20 the loops 11 on the other side. The loops 11 form guides for a slider. Fig. 2 shows two lengths which are simultaneously woven so that the coupling heads of the synthetic material threads 3a, 3b are interlocked. A mandrel or wire 32 is used around which the threads 3a, 3b bend, at alternate deformations. In this method the wires 3a, 3b bend inside the widths of the lengths so that flattened coils are formed, the textile warp and weft threads securing the coils in place.

[Also in Group XXXVI] A surface of a semi-conductive device is mounted on a matching surface of a heat sink by means of a heat-transmitting adhesive containing a single layer of particles which determine accurately the spacing of the device from the mounting. The particles may be electrically insulating abrasive powders and it is stated that if the largest of the particles have a diameter of about 8Á, a 15/100 volumetric ratio of particles to adhesive is convenient; if the maximum dimension is 4Á a ratio of 5/100 is suggested.

Abstract: 535,466. Sulphonium compounds. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. March 8, 1940, No. 4359. Convention date, March 28, 1939. [Class 2 (iii)] Sulphonium compounds are freed from admixture with an excess of thio-ethers by treatment with lower boiling liquid hydrocarbons or with lower boiling ethers. It is preferred that the sulphonium compounds should be dissolved in water prior to the extraction. The sulphonium compounds may also be extracted with two mutually immiscible. solvents in countercurrent, one solvent of which dissolves the sulphonium compounds, and the other dissolves the thio-ethers. The treatment may be carried out under raised pressure. This will always be the case when solvents are used which have boiling points below room temperature under atmospheric pressure. The mixture of thio-ethers and sulphonium compounds usually treated by the process of the invention comprises the reaction products of thio-ethers and sulphuric acid esters in which.a molecular excess of thioethers in present. Solvents specified include the hydrocarbons butane, pentane, hexane, a lower boiling gasoline, and benzene, and the ethers di-ethyl, di-isopropyl-, and methyl propyl ether. In an example the reaction product of dimethyl sulphate and dodecyl ethyl sulphide was allowed to stand and separate into two layers, whereupon the lower layer was washed 3 times with pentane. Evaporation of the pentane yielded pure thioethers, while the residue comprised sulphonium compound. Specification 509,871 is referred to.
