Filed: 1921-02-04
Abstract: 178,969. Kern, R. Feb. 4, 1921. Currycombs.-The bristles b of a wire brush, instead of being approximately at right angles to the base d, as shown, may be inclined towards one side, the brush functioning as a combined brush and currycomb. The same brush may be used to curry both coarse and soft-haired horses according to the direction in which the brush is applied. The bristles consist of a number of slightly divergent U-shaped wires inserted to form an oval surface in a base of rubber-cloth so that they cause the lower side of the rubber-cloth to be tensioned and arched. The cloth is backed by a sheet of felt e and is held in position within the curved edge c of a metal plate a, an air cushion being formed between the sheet of felt and the metal plate. After each depression of the brush in use, the air cushion is re-formed owing to the resiliency of the wires.

Title: Process for the dressing od accumulator scrap
IPC: B03B9/06
Filed: 1972-01-28
Abstract: 1364018 Recovering lead from accumulator scrap KLOCKNER - HUMBOLDT - DEUTZ AG 28 Jan 1972 [29 Jan 1971] 4216/72 Heading B2H [Also in Division H1] A process for recovering lead from old accumulators comprises crushing the accumulators to produce a mixture of fine material and coarse material, removing the coarse material, e.g. by sieving, desuldging the fine material, feeding the fine material to a further crushing apparatus, and then feeding it to a grading apparatus. The fine material obtained after the first crushing operation comprises a mixture of lead oxide, lead sulphate, metallic lead, and a small quantity of synthetic plastics material from the accumulator housing. The second crushing operation only deforms the metallic lead and synthetic plastics material but completely pulverises the lead sulphate and lead oxide present, thus permitting separation by wet or dry sieving or by using cyclones, spiral grades or rapid percussion tables. The coarse material obtained after the first crushing operation is fed to a sink-float installation and the sinking material, after removal of iron using magnets, subjected to a crushing and grading process to separate the metallic lead from any lead oxide or sulphate present.

Abstract: 1440897 Glass mixtures LICENTIA PATENT-VERWALTUNGS GmbH 30 Jan 1974 [31 Jan 1973] 04244/74 Heading C1M [Also in Division H1] In a method of producing resistors by applying a layer 4 of resistive parts (e.g. glass frit and metal and/or metal oxide) to a substrate 1, an absorbing layer 5 is also applied which selectively absorbs part of the paste constituents (e.g. the glass frit). Layer 5 is of insulating material, e.g. barium titanate, and by varying the amount applied, the resistance between electrodes 2, 3 is correspondingly determined. Layers 4, 5 may be applied in any order, and may be fired individually or together. After firing, the resistance may be adjusted by partial etching or abrasion and a protective layer may then be applied. A capacitor 6, 7, 8 may be produced simultaneously with a resistor, layer 5 serving as the capacitor dielectric.

Title: Improvements in and relating to transmitters for wireless telegraphy and telephony
IPC: H04L27/04
Filed: 1920-02-11
Abstract: 166,300. Macrorie, A. K., and Shearing, G. Feb. 11, 1920. Thermionic oscillation generators.-In systems in which the plate circuit of a thermionic generating-valve K, Fig. 3, is connected to the aerial circuit through a blocking condenser L, and is supplied with low-frequency alternating current by the secondary A of a supply transformer, for the purpose of generating tonic trains or groups of oscillations, resonance is liable to occur in a circuit from earth through part of the aerial inductance M, the anode tapping-connection, and the stray capacity of the transformer winding A. Energy is thus diverted from the aerial circuit, and the current in the aerial falls to a low value for wave-lengths in the neighbourhood of this resonance frequency. The choking inductance F may be varied to alter the frequency at which this disturbing resonance occurs, or a condenser Q of small capacity may be connected across the winding A, thereby securing uniformity of the aerial current for the entire range of wave-lengths used in practice. In the arrangement shown in Fig. 2, thermionic rectifiers D, E are provided in the anode circuit of the valve K, and the group frequency of the oscillations is either the same as or twice the supply frequency accordingly as a switch T is open or closed. By closing a switch P as well as the switch T, so as to introduce a smoothing condenser B, continuous waves may be produced instead of groups of oscillations. In this arrangement shunt resonance may occur through the stray capacity of the secondary R of the transformer supplying the rectifier filaments, and may be similarly obviated by means of a condenser Q.
