Filed: 1936-10-24
Abstract: 463,778. Viewing-apparatus. BUSCH AKT.-GES., E., and MARTIN, K. Oct. 24, 1936, No. 28980. [Class 97 (i)] [Also in Group XI] In a combined pocket torch and magnifier the magnifying lens is arranged on one side of the instrument between the battery and reflector of the torch, allowing observation through a corresponding opening on the opposite side of the casing. As shown the torch consists of the bulb e, the reflector f, and lens g. For illumination with the magnifier the bulb h is used. The switch contact p is operated by the knob k. When the catch o is engaged with the notch l the current is fed to the bulb e ; when engaged with the notch n it is fed through the strip r to the bulb h. When the magnifier lens b is in use the instrument is placed on the object c which is observed through the opening d.

Abstract: 694,802. Electrical tests and measurements. GENERAL ELECTRIC CO., Ltd., and THOMPSON, G. T. Nov. 27, 1951 [Nov. 27, 1950], No. 28980/50. Class 37. An A.C. impedance bridge comprises two ratio arms 1, 2 having substantially the same phase angle, and at least one of which is variable, the unknown impedance 8 with a parallel variable condenser 7, and the fourth arm comprising a resistor 5 in parallel with another variable condenser 6. The apparatus is contained in a box 32, the variable ratio n being controlled by a knob 34 also moving a pointer 35 over a scale 37 calibrated in terms of the ratio. Control wheels 38, 39 associated with calibrations 43, 44 enable condensers 6, 7 respectively to be adjusted for balance. The capacitance C 1  of condenser 6 is adjusted by wheel 38 so that C 1 /n is constant, as determined by a second scale 47 associated with pointer 35, giving the required reading for calibration 43. Balance is then remade by adjusting condenser 7 only, and the shunt capacitance of the unknown impedance 8 may be read directly on calibration 44. An additional scale 48 may be used to cover a different range of values. Specification 694,801 is referred to.

Abstract: 362,567. Treating sewage. RADERMACHER, W. and DELKESKAMP, C., 14, Sonnenbergerstrasse, Wiesbaden, Germany. Sept. 27, 1930, No. 29033. [Class 111.] In fresh-water clarification plants floating substances are removed prior to entering the settling chambers, the effluent being passed through a guide trough g provided with a slot or outlet o which is overlapped by an oblique longitudinal wall w or roof. The plant comprises settling chambers a', a<2>, sediment chamber f and fore-chamber v. The trough g is housed in the fore-chamber and its ends communicate with the chambers a<1>, a2. An inlet pipe k<1> conveys the fluid to the pipe g from which the floating substances escape through the slot o and are prevented from returning thereto by the oblique shield w. The scum &c. descends the sloping base of the fore-chamber and enters the sediment chamber f. The clarified liquid passes over a discharge baffle to the outlet pipe k<2>. The fore-chamber may be separated from the sediment chamber by a partition s provided with a valve r. A V-shaped hood may replace the oblique shield w.

A process for continuous counter-current treatment of granular solids with liquid of lower specific gravity by feeding them through a solids inlet 1 down a vertical column 2, up which liquid flows, and into a discharge tube 9 through a solids outlet 8, above which is situated an inlet 4 through which the liquid is fed into the column 2, which has outlets 7, 24, 25 through which part of the liquid is withdrawn and which can give a total withdrawal rate greater than that for feeding liquid into the column 2, the remaining liquid passing through the outlet 8 to propel the solids along the tube 9. In the form shown the tube 9 leads to a point above the outlet 8 and above the inlet 1 and to a solids separator (e.g. a screw conveyer 11 with a perforated tube), the liquid then being recycled to the inlet 4 through a pipe 14, the solids being carried to a pipe 12 leading to the next working stage. The column 2 may have a jacket 17 to heat or cool to maintain it at a specific temperature. The liquid outlet 6 has a pump or valve 7 therein to make it adjustable and the outlet(s) 22 and/or 23 may be adjustable.

Title: Improvements relating to "brush" bristles and to the treatment of nylon and other artificial monofilaments for producing said "bristles"
IPC: D06M13/152
Filed: 1953-10-23
Abstract: Synthetic filaments, particularly nylon, are roughened by treatment with a reagent which attacks the material of the filaments, the reaction being limited so as to produce a surface roughening only by subsequent treatment with a neutralizing agent, with or without washing by water.  Preferred roughening agents are nitric, hydrochloric, sulphuric or formic acid, or a phenol. Hydrochloric acid may be used in the vapour phase by passing the filaments through a chamber containing hydrogen chloride.  The filaments are dyed before or after the roughening and cut lengths then assembled for use in paint and like brushes.  The roughening treatment delustres the filaments, improves their paint-holding properties, and facilitates their dyeing with manganese dioxide, which may be used in various concentrations to produce colours ranging from off-white, and through varying shades of brown to black.  Differently-coloured cut lengths of filaments may be blended to imitate more closely a real bristle brush.  The roughening treatment may be carried out on cut lengths of filaments, or on a continuous filament, preferably after stretching. Several filaments collected on one reel may be simultaneously treated, the bundle being passed through a comb-guide to separate them prior to entering the treating bath. In an example, nylon filaments are withdrawn from a reel, separated and guided by rollers through a sulphuric acid bath diluted to a specific gravity of 1.3, at room temperature for 1 minute.  The bath is constantly agitated. The filaments then pass through plastic covered squeeze rollers, through a bath of running water, into a bath containing 5 per cent sodium carbonate for 5 minutes and again washed in running water.

Abstract: 722,493. Making contact springs. TELEFONAKTIEBOLAGET L. M. ERICSSON. Nov. 20, 1952 [Nov. 28, 1951], No. 29361/52. Classes 83 (2) and 83 (4). Bending.-In a method of bending spring contacts for electromagnetic relays the springs are bent between dies &c. controlled by regulating linkage which applies greater pressure to a thin spring than a thick one. In order to obtain a constant pressure P in straightening springs of the same material but of different thicknesses a greater deflection has to be applied, the thinner the spring, Fig. 4, not shown. To bend the springs dies 15, 16, Fig. 7, or shaped rollers may be used. The die 15 is adjustably fixed and the die 16 is moved by pressure controlled by linkage, Fig. 10. Both dies may be formed with surface indentations 17 on parts of varying or equal curvature. To regulate the pressure applied to a spring the die 16 is moved by a lever 28 on a fulcrum 29 and actuated by a member 35 controlled by flexed conical discs 33, 34 adjusted by screws 42 to apply pressure over a range R of displacement of the discs where the pressure q applied decreases with the displacement. In order to apply an additional constant pressure to the lower die 16 a sliding mass m may be adjusted on an arm 40 connected to the end of the lever 28. The lower die is lowered by a cam 46 which lifts the arm 40. A cam 45 moves laterally a sliding wedge 43 for releasing the top die 15. In a modification, Fig. 13 (not shown), a spring-urged toggle replaces the discs 33, 34. Shaped rollers may be substituted for the dies. The springs may be bent before detachment from the strip, Fig. 11 (not shown), or fed after detachment by pins on an endless band, Fig. 12 (not shown).
