Title: Improvements in or relating to wrapping machines for confections, sweetmeats or likearticles
IPC: B65B35/20
Filed: 1933-02-28
Abstract: 399,392. Wrapping-machines. HESSER, MASCHINENFABRIK - AKT.- GES., F., 99, Olgastrasse, Cannstatt, Stuttgart, Germany. Feb. 28, 1933, No. 6024. Convention date, Feb. 29, 1932. [Class 94 (i).] ] In a machine for wrapping sweetmeats and like articles having curved surfaces, and in which a feeler locks the wrapper feed if no article is present, the feeler is formed with a guide surface extending in the direction of the feed of the articles, and serves to prevent displacement of the articles in the guide channel. The articles 1 are fed in troughs 3, shown in plan in Fig. 6, and are moved therefrom to the wrapping station in two steps by a forked pusher 4. The pusher 4 is mounted for horizontal and vertical movement and descends upon the article so that two downwardly projecting parts 41, 4<11> lie at each end of it, and then moves to the right, Figs. 1 and 3, to take the article with it. During this feed, the shoe 38 of the feeler 37 rests on the article and is kept in the .raised position shown in Fig. 1 at the same time acting as a guide to prevent the articles from being displaced. If no article is present, the shoe descends to the position shown in Fig. 3, being caused to rock about its pivot 35 by a spring 43. This causes a roller 42 to rock a lever 46 so that a detent 49 on the part 48 of the lever locks a bar 50 in its upper position and prevents the operation of the paper feed. A tappet 39 on the rod 20 which imparts the vertical motion to the pusher 4 releases the parts in readiness for the next cycle of operations. After having been brought to the middle position shown in Fig. 1, the article is pushed to the right-hand position shown in broken lines by the extensions 4<1>, and is then beneath a member 28 which pushes it into the folding mechanism.

Abstract: 640,596. Water-tube steam boilers. BABCOCK & WILCOX, Ltd., and SCHAAP, W. F. C. Feb. 27, 1948, No. 6034. [Class 123(ii] A steam boiler comprises a furnace chamber 1, a superjacent gas pass 6 locating a superheater 7, 8 screened by a bank 12 of steam-generating tubes, a superheater by-pass passage 15, and a lateral gas outlet passage 10 leading from the pass 6 to an outlet 67 locating economizer sections 68. The tube bank 12 is constituted by two rows 21 of tubes which extend from a lower header 20 to an upper steam-andwater drum 11 and further pairs of rows 22, 24 extending from a second header 23 to said drum 11. Further tubes 17 line the front wall 3 and roof 9 of the boiler from the header 20 to the drum 11, and, similarly, the rear and side walls 4. 5 respectively are lined with tubes 25 extending between headers 26, 28 and tubes 31 between headers 32, 33. The tubes 21 initially line the lower part of the wall 3, being disposed between the tubes 17, and are Dent parallel with the tubes 22, 24 to span the furnace chamber 5, and all these tubes are bent upwardly adjacent the rear wall 4, the tubes 24 in a common vertical plane to form a wall 13 between the gas pass 6 and bye-pass 15 and the tubes 21, 22, also in a common vertical plane, to form the rear wall 14 of said byepass. At about the level of the top of the superheater section 8 the byepass is closed to a greater or lesser extent by a row of removable tiles 66, and above the tiles the tubes of the walls 13, 14, in sets of four, are bent forwardly or rearwardly and into a common vertical plane, perpendicular to the axis of the drum 11, to extend through the roof 9, between the lining tubes 17 thereof, to said drum, opening into a lower compartment 40, defined by a longitudinal partition 41, within the latter. The drum 11 also locates two rows of centrifugal steam separators 43, in communication with the compartment 40, and steam scrubbers 46, 47. The separators 43 may be of the kind described in any of Specifications 530,325, 542,610, 547,413, 547,414, ..[all in Group II], and 573,879. Water is supplied to the several headers by downcomers which are disposed in three lateral rows 50, 51, 51/51, 51 and extend from the drum 11 at positions between the tubes 13 14, the partition 41 being fitted with radial nipples 45 projecting into the ends of said downcomers. The tubes 50 lead direct to the header 23 and the two rows 51 to a horizontal header 52 the latter being disposed above the wall 3 and connected at its ends to downwardly-extending manifolds 53 provided with distributers 54 leading to the other headers 20, 28, 33. The header 52 is supported by suspension means 54 and is' provided with supporting lugs 55 for the front wall tubes 17.

Abstract: 491,450. Converting. RADIOAKT.-GES. D. S. LOEWE. March 1, 1937, Nos. 6066 and 6067. Convention dates, March 3, 1936 and March 12, 1936. [Class 38 (ii)] [Also in Group XL] A sinusoidal potential 1 is applied directly to one valve 3, and through a phaseshifter 5 to another valve 2, which is in series with the same E.M.F. 6 as the first and tends to complete the circuit when the other tends to interrupt it under the influence of the applied potentials so that short impulses are produced through current only traversing the common circuit 7 during the difference in time due to the phase-shifter. The valves may he in a common high vacuum and comprise controlling grids 106, 105 which control in spatial succession an electronic stream from a common cathode. The grid 105 is connected through the phase-shifter 107, 108 to a potential in opposite phase to that applied to the grid 106. The phase shift is adjusted by varying the condenser 107 which is associated with the resistance 108. For frequency multiplication, the duration of the impulse is adjusted to be equal to half the desired period, and the anode circuit is tuned to the desired frequency, and two pentodes, arranged as above are preferably used in push-pull to double the impulses and thus decrease the decrement of amplitude, Fig. 4 (not shown).

Title: Constant-pressure hydraulic flow control apparatus
IPC: G05D16/10
Filed: 1962-02-16
Abstract: 954,412. Valves. J. KIRSCH. Feb. 16, 1962 [Feb. 20, 1961], No. 6078/62. Heading F2V. A main, movable closure member 46, Fig. 2, co-operates with a seat 16 to prevent fluid flow therethrough from an upstream chamber 30 to a downstream chamber 32. These chambers may also intercommunicate via both a passage 60, 62 through the member 46 under the control of a first spring-loaded movable closure member 66 having a projecting stop 65, and a further passage comprising an orifice 80, the spring chamber 64 at the back of the first member 66, a duct 82, a chamber 88, Fig. 3, and a port 102 controlled by a second spring- loaded movable closure member 120 embodying a central bore 112 whereby air may pass from the chambers at opposite ends of the bore in which slides the member 120 so avoiding interference with the functioning of the valve spring. With the upstream chamber 30 filled with fluid, some of the latter passes through orifice 80, to chamber 88 and some fills passage part 60. Should chamber 30 be subject to a given higher pressure then the first member 66 is lifted and passage 60, 62 is opened; due to the delay caused by the orifice 80, to this higher pressure being established in chamber 64, the upward movement of the first member 66 forces the fluid therein into chamber 88 and thereby moves the second member 120 against its spring-loading to connect chamber 88 to port 102. Concomitantly the pressure drops in chamber 64. Since interconnection of passages 60, 62 has reduced the pressure in chamber 30 the spring of the second member 120 acts to close the latter so that the pressures across the first member 66 tend to equalize and the latter is urged to close under the action of its spring. This throttling action continues with a " hunting " motion as the first member 66 seeks an equilibrium position, and the second member bleeds-off pressure through port 102 faster than it can flow through restriction 80. The pressure in chamber 10 is thus maintained constant. If the fluid flow is reversed the main closure member 46 is unseated in the manner of a check valve to interconnect the chambers 30, 32. The member 46 incorporates a through passage 124 with a burster disc therein which would rupture at high pressure such as might occur if the fluid leaked into the end chambers of the second member 120 and hydraulically locked the latter. In a modification, the first and second members 166, 192, Fig. 4, are installed in the head of a tubular piston 142 slidable in a cylinder 144, the piston 142 containing a free piston 146 and having a closure cap 148 the whole forming a reciprocable hydraulic motor 150, e.g. a die press. The space beneath the piston 146 is filled with compressed gas, e.g. nitrogen or a spring and the bursting disc is replaced by a ball check valve whereby the fluid may be transferred from one to the other chamber upon the suction stroke. Air and/or leakage oil from the end chambers of the second member 192 are vented through passage 204.

Abstract: 332,910. Stadtberger H³tte Akt.- Ges., and Feld, G. Feb. 26, 1929 Minerals oil, purifying.- Liquid hydrocarbons, e.g. toluene or benzene, are desulphurized by treatment, in the absence of steam or hydrogen, with finely divided copper prepared by precipitation from solutions of copper salts by iron or other base metal, and subsequently heating the precipitated metal above 100‹ C., without oxidation, in a reducing atmosphere if necessary, the said treatment with copper being preceded, if desired, by a partial removal of sulphur or sulphur compounds by known methods. The desulphurizer so prepared is used as such and is not deposited on a support. In a suitable apparatus the liquid hydrocarbon. which is preferably completely dehydrated, e.g. by calcium chloride, enters through an opening C at the base of a vertically disposed tube B and is forced up through the lower aperture of the trap E, surrounded by one or more heating coils 1, and through the desulphurizer supported on the said trap E. The desulphurized oil then rises through cooled tubes in a jacket K, and through a filter G which retains any particles of copper, and finally emerges at an aperture D. The desulphurizer is stirred by a device H. Fresh desulphurizer is introduced through a pipe A, and the exhausted material removed through a tube F. A plurality of such tubes B may be employed in counter current. In an example, 4 cubic metres of benzene are treated at 15‹ C. in 24. hours with 100 kgs. of the desulphurizer, during which period 4 batches of 6 kgs. of fresh desulphurizer are added, and similar quantities of the used material are removed.
