Title: Improvements in or relating to the treatment of flexible materials with powder, granu
Inventor: REED JOHN ALVA
IPC: B05C19/04
Filed: 1950-02-01
Abstract: 693,619. Powdering flexible materials. TOOTAL BROADHURST LEE CO., Ltd. Feb. 27, 1951 [Feb. 1, 1950; Feb. 3, 1950], Nos. 2561/50 and 570/53, (the second Provisional Specification being divided out of the first Provisional Specification). Class 42 (i). A method of treating flexible materials with powder, granular matter or the like comprises passing the material along a predetermined path and applying the powder or the like thereto during such passage, and subsequently moving the material through the same path in the same direction, except that, during its second passage, the material is moved out of the said path and returned thereto through a bight which by-passes a portion of the path, and the powder is removed, or largely removed, from the material whilst passing through the bight. The materials treated may be knitted or woven fabrics in the length, or articles of woven or knitted textile yarns, or paper or flexible non- fibrous material such as flexible film. Articles such as wearing apparel are preferably secured to a length of flexible backing or conveying material, as by stitching. The powder may be applied by passing the material 1 from a roll 2 over a feed roller 3, beneath a bar or roller 4, which can be moved to alternative positions 5a, 5b, over a scrimp bar or roller 7, beneath a hopper 8, and over a roller 13, the material being wound or batched at 14. The hopper 8 may be provided with a mechanical or electromagnetic agitator 9, and with a rotary agitator 10 for the contained powder. Two or more hoppers, which may or may not be vibrated in synchronism, may be arranged in series. The powdered material, after a period of storage if required, is replaced at 2, and passed through the same path, except that the roller 4 is in the position 5b, which brings the material into the path of a rotating beater 16, which may be a rotary brush or a cage or drum fitted with transverse bars. The machine may be enclosed in a casing 18, from which the liberated powder may be removed through a discharge connection 20, and recovered by filtration or electrostatic precipitation. The application and removal of the powder to and from the material may be assisted by electrostatic means. Besides heating and brushing, the powder may be removed by suction or blowing, or both, or by passage through a bath of suitable liquid at the bottom of the bight, or by a combination of such treatments. The process may be applied to the treatment of fabrics containing wool with bleaching powder or mixtures containing this, in order to reduce their tendency to felt. Specification 654,739, [Group IV (c)], is referred to.

Filed: 1939-01-28
Abstract: 524,359. Control of several motors. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and COOPER, V. J. Jan. 28, 1939, No. 2987. [Class 38 (iii)] [Also in Group XL] A radio transmitter is started up by automatically bringing circuits L1 C1 ; L2 C2 ; L3 C3 ; L4 C4 into tune successively with the frequency applied to the grid of the valve V1. Momentary closure of switch sl causes contacts e1 to lock closed and motor M1 to operate until circuit L1 Cl is in tune causing the current in relay coil A to pull and contacts a1 to open. Motor M2 runs slowly until contacts a2 close whereupon it runs quickly until contacts b1 open due to fall of current in relay coil B. Similar action occurs with motor M3 under control of relay D and contacts dl. Thereupon M5 tunes the aerial circuit until the current in relay C has risen sufficiently to open contacts c2. Motor M4 initially lightened the coupling between L3 L4 until limit switch mm was opened, but upon closure of contacts c7 resumes its motion until contacts d3 are opened by relay D which has been changed in its setting by the opening of contact c5. Opening of contact c4, d4 causes release of contacts e1
