Title: Improvements in the manufacture of soap
IPC: C11D13/02
Filed: 1944-02-24
Abstract: 575,949. Soap manufacture. ELLIOTT, W. H., and BLACKMAN, J. Feb. 24, 1944, No. 3442. [Class 91] In the cold process of making soap, in order to accelerate the saponification and to render the product less brittle, a pre-formed mixture of rosin fat or oil, and caustic potash insuffic:ent to saponify all the rosin is added to the mixture of fat or oil and alkali from which the soap is being made in a crutching pan or equivalent vessel and the whole thoroughly mixed. The mixture is allowed to thicken in the vessel and to remain therein until the mass again becomes liquefied whereupon a further quantity of alkali is added to complete the saponification. The latter is therefore finished prior to discharge into the cooling or forming vessels. The fatty material in the rosin-oil-potash mixture may comprise crude fatty oils, acid oils, fatty acids, skin greases, tallows &c. In an example, the soap is made from palm kernel oil and caustic soda. Fillers, antiseptics, or medicinal substances, may be incorporated in the soap before its final discharge from the crutching pan. For making soap powder, soda ash and water are added to the soap in the crutching pan to obtain the consistency required for spraying and the mixture is then pumped directly to the spraying chamber. Specification 432,227 is referred to.

Abstract: 1428305 Sorting utilizing radiation detectors BORDEN Inc 25 Jan 1974 [26 Jan 1973] 03483/74 Heading G1A Containers are examined with x-rays, and those containing undesired solid bodies are rejected. In Fig. 1 containers 12 are carried on belt 14 to a screw drive 20 which is driven in synchronism with the mains A.C. supply by a motor 22. When a container reaches the region of x-ray source 26 the source is activated by a light source and detector 30, 32; the x-ray source is synchronized with the mains supply so that the container, whose position is determined by the A.C. driven screw, is opposite the x-ray source when emission occurs. After passing through the container the x-rays strike image intensifier 28, producing an image at 29. This is scanned by TV camera 34 and displayed on TV monitor 40 so that any solid body appears as a bright spot. Such a spot is detected by photo-multiplier 44 whose output, suitably  delayed, operates a rejector 48. Masks 36, 38, 42 control the various fields of view; further control is possible by processing the signals from the camera 34 so as to display only a part of its field of view at 40, Fig. 2 (not shown). This processing also includes pre-set thresholding so that the sensitivity may be controlled in different parts of the display.

Title: Improvements in or relating to tobacco feeding devices
IPC: A24C5/39
Filed: 1932-02-05
Abstract: 396,788. Cigarettemaking machines. MILLER, C. W., 2, Am Hochwald, Weisser Hirsch, and UNIVERSELLE CTGARETTENMASCHINEN FABRIK J. C. MILLER & CO., 48, Zwickauer-Strasse, both in Dresden, Germany. Feb. 5, 1932, No. 3520. [Class 130.] Tobacco is fed or placed in a number of containers, in which it is seasoned and stored, after which it is fed directly to a conveyer leading to a cigarette-making machine. As shown in Fig. 2, cut tobacco is taken from boxes 1 and spread uniformly in containers formed by walls 41, 42 and by conveyer belts 2, 3, 4 respectively.. The tobacco remains on the belts 2, 3 or 4 until it has assumed a uniform temperature or moisture content, and the containers may be provided with covers to facilitate the seasoning. After seasoning, the tobacco is fed to a cigarette-making machine which is located in a separate room. By closing a switch on the cigarette-making machine, a shaft 9 is set in rotation by an electric motor 15, and current is interrupted to solenoids which actuate slides 17 to close hoppers 16 ; also magnets 13 are energized which, through levers 11, close clutches 10 driving the shafts 6 over which the belts 2, 3, 4 pass. A star wheel and a brush assist the discharge of the tobacco into the hoppers 16, from which the tobacco is conveyed pneumatically to the cigarette-making machine. While tobacco is being fed from one belt, fresh tobacco is placed on another belt. In the arrangement shown in Figs. 4 and 5, tobacco is supplied through a pipe line 26 to a container 25 and is discharged through an airlock 27 on to a conveyer belt 29, dust and the air used for the conveyance of the tobacco passing through a conduit 28. The belt 29 is formed as an endless belt which can be driven in either direction, and is mounted on a sliding carriage so that the tobacco is discharged from the belt 29 into one of the containers formed by belts 35 .. 38 and side walls 30, which are lined with sheet zinc. After charging, the top of the container is covered until the tobacco is discharged by setting the belt 35, 36, 37 or 38 into motion and allowing the tobacco to fall on to a conveyer belt 31 leading to a distribution place 32, where operators throw the tobacco into hoppers 33 leading to the cigarette-making machines.

Abstract: 1326877 Gauging stops B & R PRODUCTS PTY Ltd 26 Jan 1972 [29 Jan 1971] 3560/72 Headings B3E and B3W The spacing of gauging stops 50, mounted for adjustment along rails 47 in a guillotine or press brake, is determined by punching holes in a metal strip 11 at the required intervals measured by an odometer 18 as the strip is fed through a guide 10. The strip is then applied to the stops 50 which are moved along the rails so that they engage in the punched holes. The strip is fed through the guide by manually rotating one roller of a pair of knurled rollers 35. The punch 23 is mounted in a hand-actuated holder 28 which also carries a blade 26 to sever the punched length of strip. Each rail 47, Fig. 5, is cruciform and has a brass conductor strip 48 on its underface and each stop 50 is upwardly spring-loaded in a block 57. The block is clamped to the rail flange 58 by a releasable lock screw 60. An insulating sleeve 54 and disc 55 respectively surround and surmount the stop so that  a metal workpiece can ride over a stop, depress-  ing it into the block 57 and only making electrical contact with a stop when it engages the side of the stop for energizing a solenoid valve to operate a clutch. To space the stops relative to the guillotine blade or bending beam a set up block 42 is mounted on the fixed blade or die with a depending pin (44), Figs. 4 and 6 (not shown), located in the end hole of the strip.

Title: Improvements in or relating to x-ray installations
IPC: H05G1/46
Filed: 1933-02-06
Abstract: 409,476. R÷ntgen-ray apparatus. MULLER AKT.-GES., C. H. F., 24, R÷ntgenstrasse, Hamburg, Germany. Feb. 6, 1933, No. 3603. Convention date, Feb. 8, 1932. [Class 39 (i).] In installations for making short photographic exposures and having control devices for adjusting the voltage across the X-ray tube and the time of the exposure, the current through the tube is controlled so that the average current during an exposure is greater if the time is adjusted to a smaller value at a definite voltage adjustment and if the voltage is adjusted to a lower value at a definite time adjustment. The power supplied to the tube is made independent of the particular voltage used and the tube may always be loaded up to the limit of its power and the exposure made in the shortest time. In one arrangement in which a time switch 24, Fig. 1, controls through a relay 25<1> the closure of the supply circuit to the high-tension transformer 4 for the X-ray tube 1, a short 25<11> across a resistance 26 in the cathode-heating circuit is removed, or the heating circuit is broken, when the transformer 4 is energized at the beginning of an exposure. The resulting decrease in cathode-heating current causes the cathode to cool and the current through the tube 1 to decrease during the exposure, the average current being thus less if the exposure is larger. The voltage applied to the transformer 4 is controlled by an autotransformer 7 with tappings selected by a control drum A. On this drum, or on a drum coupled thereto, are contacts controlling the amount of a resistance 22 in the cathodeheating circuit and so decreasing the current through the tube 1 as the voltage is increased. In a modification in which the current through the tube 1 is constant during the exposure, the coupled voltage and current controls A, 22 are retained and the adjusting shaft 29, Fig. 3, of a time-switch is coupled to a control 27 for an autotransformer determining the cathode-heating voltage so that the cathode current is decreased if the time of exposure is increased. The shaft 29 carries a pin 30 bearing against a pin 32 to turn the control 27. During the exposure, the pin 30 turns to the left but the control 27 is held stationary by a catch 33, the control 27 being returned to its normal position by a spring 35 when the catch 33 is released at the end of the exposure.
