Abstract: 473,178. Splitting fibres, hairs, or the like for brushes. BAYER, L. March 3, 1937, No. 6327. Convention date, Dec. 5, 1936. [Class 19] A machine for splitting horse-hair, vegetable fibre, or the like, by means of needles mounted on a rotatable carrier, is characterized in that the needles are arranged more densely at those places where they meet the outer strands of the bundle of hair, &c., than towards the centre of the bundle. In the example shown the needles are formed in rows on plates d which are mounted on the end of a rotatable cylinder e. The rows of needles are slightly inclined to the longitudinal axes of the plates d. The needles are more densely arranged at the ends d<1> of the plates. The needles may also be more densely arranged at those ends of the plates which are nearer the centre of the cylinder than at the other ends. The plate d may be flat or may be curved, as shown, to fit the ball-like form of the end of a bunch of fibres. The fibres K are held in pincers i during the slitting process, a support h being provided for the process. The driving means is preferably arranged so that the direction of rotation of the cylinder e is reversible. The plates d may be mounted on the cylindrical portion of a rotatable carrier instead of on the end. The needles may be arranged directly on a carrier instead of on separate plates and the density of their distribution need not change in a continuous manner.

Title: Radiation measurement by means of a glow discharge counter
IPC: G01T1/18
Filed: 1954-03-08
Abstract: 779,455. Measuring radiation. SIEMENS & HALSKE AKT.-GES. March 8, 1954 [March 6, 1953], No. 6629/54. Class 40 (3). In a method of measuring electro-magnetic radiation of wavelength equal to or less than that of ultra-violet light a voltage in excess of the ignition voltage is applied to a pair of electrodes in a gaseous atmosphere or as to produce a discharge, the glow discharge is extinguished by an extinction circuit and the ignition voltage is not re-applied until the " after-effect " period has elapsed. The " aftereffect " period is the time elapsing after a first ignition during which the period of delay of re-ignition is affected by the first discharge. Hence, if the ignition voltage is not re-applied until this after-effect has died away, the ignition delay in the absence of after-effect is then a measure of radiation intensity. The Specification states that a number of electrode materials have been discovered which exhibit only a very small after-effect. Such electrodes may be of silver steel, V2A steel, or nickel and may be purified by heating by high frequency in a high vacuum for several hours at 500‹ C. The gas filling of the tubes should be inert gases such as neon or argon of maximum purity. An example of a suitable arrangement is shown in Fig. 1 in which a supply voltage from a battery 5 in excess of the ignition voltage is applied to the electrode between which a glow discharge is produced by radiation when condenser 4 discharges through the tube until the potential across the tube falls and it extinguishes. The operating voltage is not again sufficient to trigger the tube until the after-effect period has elapsed and the delay is determined by the time constant of resistor 3 and condenser 4. Once the necessary voltage has been re-established the delay in ignition depends only on radiation intensity. The voltage pulses developed at condenser 4 are tapped through condenser 7. In the modification of Fig. 3 (not shown), an alternating supply is used, the frequency of which is such as to extinguish the tube and not to re-apply the igniting voltage until after the delay period has elapsed. Fig. 4 (not shown) uses the arrangement of Fig. 3 to trigger an A.C. fed valve with an integrating circuit and its anode load while in Fig. 5 (also not shown), the output pulse discharged by the firing of the glow-discharge tube triggers further glow-discharge tubes through which a condenser discharges operating a relay or integrating device.
