Title: An improved apparatus for the delivery of measured lengths of filamentary material
IPC: B65H61/00
Filed: 1944-06-02
Abstract: 586,163. Measuring thread &c. LANDIS & GYR SOC. ANON. June 2, 1944, No. 10646. Convention date, June 11, 1943. [Class 120 (iii)] [Also in Group XIX] Apparatus for the delivery of measured lengths of thread, wire &c. and provided with a measuring wheel and a counter, is characterized in that, between the measuring wheel and the lowest calibrated numeral wheel of the counter, there is provided transmission means including one or more tens-transfer mechanisms of the stepby-step type. The measuring wheel 2 drives the tens-transfer wheels 4, 7, 8 through reduction gearing 3, the wheels 4, 7, 8, in turn, driving numeral wheels 9, 10 of the tens-transfer type, the numerals thereon being visible through an inspection opening in a casing provided with a multiplying factor whereby the true length of material may be computed. The wheels are each provided with a zeroising heart 11 whereby they may all be set at zero by a hand lever 12. The numeral wheels 9, 10, having been set to the desired length, rotate in a subtracting sense until depressions 14 therein come beneath feeler rollers 15, attached to a shaft 16, to allow the rollers to fall thus turning the shaft 16 and hence a further shaft 18 so that a detent 19 is moved to release a lever system 22, 23 which operates a pivoted razor blade 24 to cut the filament. The rollers 15 and razor blade 24 are reset from cams 28, 29 operated by the hand lever 12.

Abstract: 1497972 Packing stacks of flat flexible articles in enveloping bags; stacking sheets WINDMOLLER & HOLSCHER 17 March 1976 [20 March 1975] 10758/76 Headings B8C and B8R An apparatus, for packaging flat flexible workpieces, particularly sacks, which may be folded, or packets of sacks 2 which are stacked in a shaft 28 and in an enveloping bag 53 inverted over the shaft 28 and comprising a slidable carriage 23 reciprocable in the shaft 28 and a backing member 43 disposed above the shaft, is characterized in that the slidable carriage 23 consists of supporting bars 19-22 of upwardly U-section steel, and that retaining bars 42À1 are provided at the top of the shaft 28 and insertable therein the retaining bars 42À1 being insertable in the U-sections of the supporting bars 19-22 when the slidable carriage 23 is extended and being, together with their driving and supporting means 42 as well as the supporting means 48, 49 of the backing member 43, fixed to a shaft 45 which is pivotally mounted on a frame 26 for the apparatus. The sacks are advanced on a belt conveyer 1, on to the carriage 23 and up against a stop 29 which can be raised for the discharge of an unsuitable stack formation, the conveyer being guided over rollers 17-18. The carriage 23, is raised by a pressure unit 25 to form an intermediate cassette of bags 2 above plates 31 mounted on levers 35 which are oscillated, toward, and away from, the shaft 28, in correspondence with the sequential raising and lowering of the carriage 23, the plates 31 being mounted for upward swinging movement to allow for a failure of a pressure drive unit 39 for the levers 35. The enveloping bag 53 is placed over the shaft 28 and the stack of bags is inserted therein by the carriage 23, the plate 43 exerting a constant counter pressure through a pressure unit 44. Cylinder units 42, mounted upon a rotable shaft 45, are then energized to extend their piston rods 42.1  which pierce through the bag walls 53 beneath the stack as they pass through slots 41 and the U-section supporting bars 19-22. As the carriage 23 is retracted to its lowermost position the shaft 45 is rotated, by a pressure unit 47 and link 46, to swing the package through 90 degrees, pull it off the tongues 27, and support it upon a guide plate 51 which is mounted upon a support 48 for the pressure unit 44 the support 48 being fixed to the shaft 45. After reaching the horizontal position the bag is closed and pushed further along the guide plate 57 for removal from the apparatus.

Title: Determination of ionizable fluorides in gases
Filed: 1959-04-01
Abstract: The preparation of a reaction product of dimethylaminoazophenylarsonic acid and zirconium oxychloride in equimolar proportions is described.ALSO:<PICT:0851270/III/1> Dimethylaminoazophenylarsonic acid (DAAPA) is reacted with an excess of zirconium oxychloride over 1:1 molar ratio in aqueous hydrochloric acid and the reaction product applied to an inert porous material to provide a detector for ionisable fluoride in a gas to be tested, which produces a deep pink to brown coloration. The reaction product may be prepared by dissolving DAAPA in a mixture of glycerin, ethanol and hydrochloric acid and adding a solution of zirconium oxychloride in hydrochloric acid.  The glycerin may be reduced or omitted or replaced by sugar.  The fine suspension produced may be applied to a filter paper or a glass fibre cloth.  As shown in the Figure, the suspension may be applied through an opening 4 in a transparent cover 3 to a filter paper 5 having holes 6 supported on a flanged funnel 1 and held in position by clamps 7.  The gas to be tested is drawn over the impregnated filter paper by means of bulb 8.  Under standardised conditions quantitative results may be achieved.  The air flow may be varied by adjusting the position of a screw 13 in a nipple 11.

Abstract: 706,239. Concrete piles. VAN HATTUM EN BLANKEVOORT, N. V. May 2, 1952 [May 2, 1951], No. 11182/52. Class 68(2) A method of introducing a pile such as a foundation pile into the ground as well as the ascertaining of the carrying capacity thereof, comprises driving an open ended tube 1, Fig. 2, into the ground, removing the earth therefrom, placing a prefabricated concrete pile 2 having an enlarged bottom end 3 in the tube 1 the diameter of the pile shaft being so much  smaller than the internal diameter of the tube that the shaft is spaced from the tube throughout its length, charging filling material 5 such as sand between the pile shaft and the tube and subsequently operating a jack 8 so as to press the pile downwardly and pull the tube upwardly. In the lower portion of the tube 1 a number of vibrating means 6 are provided, which are lowered through tubes 7, in order to compact -the filling material 5 below and around the end 3 of the pile. The tubes 7 may also be used to remove soil water which is freed during the compacting. In a modification the compacting is effected by vibrating the tube 1 by means of large capacity vibrators. The jack 8 presses against the top of the pile and also against a beam 9 bearing against projections 10 secured to the tube 1. After the jack has been fully projected the beam 9 is secured at a lower position in the tube I or the tube is removed by means of tackles not shown. In order to increase the loading of the pile during extraction of the tube, the latter may have weights or heavy objects attached thereto such as the installations employed in driving the tube into the ground and placing the pile 2 in position.
