Filed: 1935-11-27
Abstract: 444,683. Ink. MILLAR, C. F. P., Craigmillar, High Street, Chorlton-on-Medlock, Manchester. Nov. 27, 1935, No. 32951. [Class 146 (iii)] Printing-inks or vehicles therefore are prepared by heating vulcanized rubber, such as old motor car tyres, preferably with agitation, to a temperature and for a sufficient time to decompose the rubber and destroy any fabric which is present, and treating the product to remove pungent matter ; one or more vegetable or mineral oils may be added. The mass is preferably subjected to a distilling-operation up to a temperature of approximately 525‹ F. continued until the condensate is practically free from water. The product is then treated to remove pungent matter by blowing superheated steam at 475‹ F. through the mass. The cooled product, which contains 25-35 per cent of pigment, is milled and ground to form a printing-ink or may be mixed with oils, pigments, gums, varnishes, siccatives, toning- materials, or the like.

Title: Frequency measuring circuits
IPC: G01R27/32
Filed: 1971-07-14
Abstract: 1320620 Analogue to digital converter SIEMENS AG 14 July 1971 [22 July 1970] 33004/71 Heading G4H [Also in Division G1] A variable frequency oscillator is controlled to generate an upward and downward sweep repetitively, and to measure the frequency at a selectable point in the upward scan and at the corresponding point in the downward scan, an adjustable voltage representing the desired point is compared with the voltage controlling the oscillator frequency and upon a predetermined condition, e.g. equality, during both the upward and downward paths of the sweep the oscillator output is gated to a counter for a predetermined period, the sums of the two accumulated counts representing the frequency. In the application shown in Fig. 1 the frequency sweep of an oscillator 1, controlled by a saw-tooth voltage Us, is fed to a four-terminal network X whose frequency transmission characteristics are under investigation and whose output after amplification (16) and rectification (17) controls the deflection plates of a CRT 19, with the control voltage Us providing the time base. Alternatively the four-terminal output may be digitised in an analyzer 25. The voltage U1, representing the point in the upward and downward sweep at which the frequency is desired, is compared in a comparator 4 with the control voltage Us and upon the two instances of equality a timing pulse 5 operates a pulse circuit 6 to generate a pulse 7 of predetermined length which opens a gate 8 to feed the oscillator signal Uv to the counter 9. The counter adds the two counts and the sum is read out for display, or alternatively storage, upon a pulse Uz from circuit 6. The comparator pulse 5 occurring on the upward sweep is sent via line 10 to generate a mark on the CRT to indicate the point on the CRT display to which the measured frequency responds. Circuit 6 (Fig. 2, not shown) includes a further counter which begins to count clock pulses in response to each comparator pulse until a predetermined count is reached, the period of counting defining the gating pulse 7.

Filed: 1936-12-07
Abstract: 486,856. Measuring capacities. O'DELL, A. E. (Haardt & Co. Akt.-Ges.) Dec. 7, 1936, No. 33533. [Class 37] A process for observing changes occurring in a material while an external influence acts upon it, whether for determining the properties &c. of the material or of the influence, by measuring the dielectric constant of a substance forming the dielectric of a condenser, is characterized by the material to be tested being placed in stationary thin flat form in contact with an electrode of the condenser and being covered by an apertured plate through which the external influence gains access to it. The material to be observed may be films, foil, fabric or other sheets and in one form which is suitable for testing wood for drying and impregnation, a thin sheet of wood is clamped between two metal plates, one of which is apertured. The dielectric constant of the wood is measured during a period of time and from the variations in its value the progress of the treatment can be determined. In a modification, the permeability of a foil S to fluid is determined by mounting the foil between apertured plates H, P<1>, the lower of which with the plate P<2> constitutes a condenser having a dielectric O, also formed of thin foil, whose dielectric constant varies with the fluid it absorbs. The spacing between the condenser plates may be determined by insulating pieces J. In a further form for measuring absorption of gases, the condenser is mounted in a pipeline and comprises a pair of apertured plates between which is clamped a foil adapted to take up gaseous ingredients. The influences acting on the test material may be temperature, pressure or the surrounding gas or liquid and the test material may be a film supported on a thin flat insulating carrier. Examples of such materials are given. Specification 276,468, [Class 37], is referred to.
