Abstract: 400,094. Washing granular materials. KRUPP GRUSONWERK AKT.-GES., F., Buckau, Magdeburg, Germany. April 7, 1933, No. 10507. Convention date, May 17, 1932. [Class 82 (ii).] Apparatus for separating solid substances of different specific gravities, particularly the kernels and husks of oleiferous fruits, comprises a tank containing the separating liquid, e.g. a suspension or solution of clay or salt, and a rotatable perforated drum dipping into the separating liquid, the perforations not being large enough to allow the heavier particles which sink to the bottom to pass through. The drum is provided with means to raise the heavier particles and discharge them through a central aperture in the front end of the drum, and with guiding and conveying means to pass the floating lighter particles to an outlet at the other end. A space is left between the drum and the bottom of the tank so that the drum does not dip into the sludge. The materials are fed through a shoot 1 into the interior of a perforated drum 2 rotated by a shaft 11 and dipping into separating liquid in a tank 2<1>. The drum is cylindrical at its inlet end and tapers to an outlet 2<11> at the other end. The heavy particles sink in the drum and are collected by pivoted scoops 3 with perforated bottoms 5 which are guided during rotation of the drum by arcuate guides 6, interrupted at the top to allow the scoops to tip and discharge their contents into a hopper 7 discharging through a central aperture in the front end of the drum into a trough 9 with a conveyer worm 8. The floating lighter particles, which are prevented from floating into the area in which the scoops 3 operate by a metal sheet 19 attached to a framework 21, are moved by guides 10 carried by a spider 10<1> on the shaft 11 towards the outlet 2<11> 'and are passed by conveying blades 12 through the outlet into a perforated drum 13 from which they are discharged by lifting pockets 14 and blades 15 into a hopper 16 leading to a perforated draining trough 18 with a conveyer worm 17. Perforated ribs 22 are attached to the periphery of the drum 2 to agitate the separating liquid.

Filed: 1924-04-29
Abstract: 237,362. Rushen, P. C., (Siemens- Schuckertwerke Ges.). April 29, 1924. Controllers with auxiliary switches; controllers with combinations of resistances.-In a controller for groups of resistances each of which is variable in steps, two switch members having lost motion relative to a handle or the like, when switching " off," change the order of the groups so as to differ from the reverse of the switching " on " order. In the arrangement shown, which represents a scheme of Ward Leonard control, two groups of variable resistances belong to the fieldwindings 2, 3 of two dynamos 12, 13 which excite respectively the field-windings of the working dynamo 32 and the working motor 33. In switching " on " from the " off " position shown, the handle 1 carries forward a sliding contact member 21 as far as the position shown in Fig. 4 and leaves it there. In further movement the handle carries round a previously stationary sliding contact member 31. When the handle is turned back, the contact 21 is moved back to its initial position before the contact 31 commences to return.

IPC: B30B15/16
Abstract: 106,653. Parsons, P. R., Clift, C. E., and Manganese Bronze & Brass Co. May 26, 1916. Presses, producing part of stroke of, hydraulically.-Hydraulic presses for the extrusion of metals and for like purposes are supplied by a set of pumps driven from an internal-combustion en. gine through a motor-generator fly-wheel set, the connexions and control being such that the non- effective part of the stroke takes place at relative. ly low pressure, and the effective part at high pressures varying according to the power required. The press consists of a main cylinder f and an auxiliary cylinder a, the ram of which is connected by a cross-head b and rods c, c<1> to the cross-head d of the main ram e. The main cylinder f is connected to the low-pressure supply tank through a non-return valve h, pipe i', and valve m. The main supply pipe k<1> from the pumps is provided with valves k, i for controlling the supply to the cylinders a, f and the retracting-cylinders g. The pumps are driven by a motor-generator iiy-wheel set of the Ilgner type. When the press is not working, the valves k, l, m are open, and water is circulated through the supply tank. By closing the valves i, m, water is supplied to the cylinders a, g, so that the ram is brought quickly up to its work, the area of the piston in the cylinder a being greater than the area of those in the cylinders g. During this movement, the cylinder f draws in water through the valve h from the tank. The valve l is then opened, so that pressure water is admitted to the cylinder f for the final portion of the stroke. At the end of the stroke, the valve m is opened and the valve k closed, so that the cylinders g only are under pressure, and the ram is retracted. No hydraulic accumulator is used in the system.

Title: Improvements in scanning head for color sorting apparatus
IPC: B07C5/342
Filed: 1951-05-07
Abstract: 699,263. Sorting photo-electrically. BICKLEY, E. H. May 7, 1951, No. 10700/51. Class 40 (iii). When sorting articles photo-electrically, those having only a small defective spot of a different colour from the rest of the article are detected by using two photo-cells in a normally balanced circuit, one responsive to the background colour and the other to the defect colour. The invention is described with reference to a system for rejecting peanut kernels which have a piece of skin adhering to them. As shown (Fig. 2), kernels are brought by a conveyer belt to a position immediately below the axis of a tube 11. There, light from a source (not shown) is reflected from the kernel and focused by lenses 21, 22 through an aperture in a mask 23. A second mask 24 cuts off stray light. After passing through mask 23 the beam strikes two photo-cells 14, 15 arranged side by side. Cell 14 is more sensitive to red rays, cell 15 to blue. The relative sensitivity of the two cells is determined by the position of a pivoted flap 31, polished on both sides and adjustable from outside the cell housing. The lamp is provided with a reflector and a shutter to adjust the total illumination. It is stated that the arrangement is applicable to control. ling the flow of liquid in transparent pipes. Circuit and operation (Fig. 3).-The red sensitive cell 14 is connected between the H.T. supply and grid of a triode 26 while the blue sensitive cell 15 is connected across the grid resistor 27 of the same tube. In the anode circuit is connected the primary coil 30 of transformer feeding a magnetic valve which controls a jet of air to eject defective kernels. The shutter is so adjusted that the presence of a piece of red skin operates the valve. Specification 615,996 is referred to.

Title: Improvements in and relating to electromagnetically controlled devices
IPC: H01F7/13
Filed: 1949-04-22
Abstract: 661,308. Valves controlled by auxiliary valves. UNITED AIRCRAFT PRODUCTS, Inc. April 22, 1949 [July 24, 1948] No. 10790/49. Class 135. [Also in Group XXXV] An electromagnet particularly of the type wherein a plunger has a relatively long travel, e.g. operating a valve or a switch, comprises a coil 38 within which reciprocate two axially aligned plungers 42, 43 separated by an air gap 44 which is maintained by a spring 32; but, when the coil 38 is energized, the spring pressure is overcome, the gap 44 closes, and the two plungers 42, 43 move together without being opposed by the spring 32. The figure shows an electromagnetically controlled valve to be inserted as a unit into a pump housing to which it is connected by threads 13. When the coil 38 is not energized, the plungers 42, 43 separated by the air gap 44 occupy the position shown, while the spring 32 pushes a rod 25 which passes through an opening 45 in the plunger 43. One end of the rod 25 abuts the plunger 42 and on the other end of this rod a needle valve 24 is formed. When the coil 38 is de-energized the needle valve 24 is open and relieves the fluid that might have passed in a chamber 23 from the pressure inlet 12 via a loose fit in the bore 11. Thus no pressure of the fluid is allowed to build up in the chamber 23 when the coil 38 is de-energized, otherwise the piston 14 is urged to open its valve 15 to the outlet port even against the main closing spring 17. When the coil 38 is energized, the plunger 42 moves first to close the gap 44, meanwhile the rod 25 is pushed by the plunger 42 and the valve 24 closes the relief fluid passage 21. The fluid pressure in the chamber 23 quickly rises and the piston assembly 20 moves leftwards to open the valve 15. Meanwhile the coil 38 remains energized and the plungers 42, 43 together with the spring 32 also move leftwards as a unit, thus leaving the valve 24 closed. When the coil 38 is de-energized, the spring 32 is effective to move the rod 25 towards the right and so opens the valve 24 with the result that the fluid pressure in the chamber 23 is relieved and the piston assembly 20 is returned in a direction to close the valve 15 by the spring 17.
