Title: Improved apparatus for dividing a quantity of powdery material into equal portions and delivering each of the said equal portions into a respective container
IPC: B65B1/40
Filed: 1934-01-22
Abstract: 432,118. Packeting-machines. ROSE A. G., and ROSE BROS. (GAINSBOROUGH), Ltd., Albion Works, Gainsborough, Lincolnshire. Jan. 22, 1934, No. 2111. [Class 94 (i)] [See also Group II] Apparatus for feeding equal measured quantities of powder into containers comprises feeding means for feeding a continuous uniform stream of powder from a hopper at a regulated rate into a series of funnels moving in succession through the stream of powder so that each in turn receives the stream of powder for the same predetermined period and deposits it into a container in register with the lower end of the funnel while it moves through the stream of powder. A feed roller 11 seals the outlet from a hopper 10 except for the space 16 which is regulated by the slide 19. A spiked roller 24, geared to the feed roller, breaks up the material as it passes to the shoot 23. An annular ring of separate funnels 29 situated above a corresponding ring of holders 33 containing bags 35 rotates about a spindle 32 and the funnels pass under the shoot 23 in succession. Equal quantities of material are thus discharged into each funnel and thence into its corresponding bag, the quantity being determined by the speed of the funnels. A conveyer belt may carry the funnels and bags under the shoot 23. The material may be discharged from the hopper by a feed-screw.

Abstract: 865,870. Cold separation of gas mixtures. SULZER FRERES S. A. Jan. 20, 1959 [Feb. 1, 1958], No. 2122/59. Class 8(2). In cooling a gas mixture e.g., hydrogen containing deuterium prior to rectification in a column (not shown) thawing of impurities e.g., nitrogen condensed in the primary passage 13 or 35, Fig. 1, of whichever one of a pair of heat exchangers 14, 29 is off-stream is effected by a reverse flow through the secondary passage 22 or 28 of said off-stream exchanger of a portion of cold separated component in a duct 17 after leaving the warm end of the secondary passage of the on-stream exchanger ; the so liquefied impurities being discharged through a valved duct 47 or 36. As shown the crude gas mixture in ducts 11, 12 traverses the primary passage 13 of exchanger 14 and deposits solid nitrogen on the exterior of the secondary passage 22 traversed by cold separated hydrogen which is divided at a point 24 into a portion throttled at a valve 6 and into a portion which traverses a line 27 and the secondary passage 28 of the exchanger 29 being derimed, after which the hydrogen traverses a line 32, a valve 7, a line 33 and a throttle valve 8 to rejoin the first portion for use as reflux in the column. Between thawing of the off-stream exchanger and switching of the exchangers, a portion of cold returning hydrogen is bled from duct 17 through valves 2, 37 and a line 38 as shown in Fig. 2 to effect precooling of the exchanger next to the onstream.

Abstract: 810,161. Applying text to kinematograph films. ERTNAES, O. Jan. 21, 1957, No. 2179/57. Class 98(2) A strip of film 1 is moved by gripping member 16 intermittently between die 2 arranged for up and down movement and cliche carrying member 3 resting on pad 4, the member 3 having a number of cliches and being moved along from one cliche to the next after the desired number of frames have been impressed with the text. The pressure may be equal for texts of different lengths, and for this the cliche carrying member 3, Fig. 2, has shoulders 5, 6 raised to the height of the cliches 7, 10, 11, which shoulders carry the greater part of the pressure. Recesses 15 in shoulder 6 are used for moving the member 3. In operation a first-applied wax coating on the emulsion side of the film 1 is removed in text formation by the cliche, the bared emulsion surface is etched away and then remaining etching liquid and wax are removed; or the film may be moistened and the cliche member heated to remove text areas of emulsion without further operations.

Abstract: 620,887. Indicating faults. WIJK, H. VAN DER. Jan. 29, 1947, No. 2734. Convention date, Oct. 3, 1942. [Class 37] A fault indicator for a single conductor system, particularly for ships, comprises two lamps in series between the main conductor and earth and an auxiliary conductor adjacent to the main conductor connected to the junction of the lamps. In the system shown generators 1 have one pole earthed and the other connected to a bus-bar 5, from which are fed distribution boxes 10, 11 and a motor 13. Sub-distribution boxes 14, 15, 16 are supplied from the box 10 and a motor 17 is supplied from the box 11. An auxiliary conductor 18 is embedded in the insulation of the cables and may consist of a conductor wrapped spirally, with short pitch, around the insulated core or of a braided wrapping or an enveloping strip. The thickness of insulation is made sufficient for the whole voltage between the core and the auxiliary conductor as well as between the auxiliary conductor and earth. At each control point a pair of lamps 19, 20, each adapted for the normal voltage of the system, are connected in series between the conductor and earth, the auxiliary conductor 18 being connected to their junction. If a fault X occurs between the auxiliary conductor 18 and earth, the lamp 20 is short-circuited and the lamp 19 glows brightly. If a fault Y occurs between the main and auxiliary conductors, the lamp 19 is short-circuited and the lamp 20 glows at full voltage.
