Title: Abrasive blast treating system and method
IPC: B02C17/18
Filed: 1972-01-11
Abstract: 1385721 Abrasive blasting; removing foundry moulds CARBORUNDUM CO 11 Jan 1972 [21 Jan 1971] 1146/72 Headings B3D and B3F [Also in Division B2] An abrasive blast treating system, e.g. for breaking open and recovering sand from bonded foundry moulds, used for castings comprises means 32 for conveying lumpy used mould material 36 from a casting stripping chamber 18 to an abrasive blasting chamber 50, blasting means 80 for breaking up the material 36, and means 94 for receiving granular material so produced. Centrifugal throwing wheels 28 break up the moulds 12 of castings 22 entering the chamber 18, mould material, including rigidifying rods 20, falling on to the conveyer 36, oscillation of which transfers the material, over a screen 40 which removes fines, on to a second oscillating conveyer 48 (and Fig. 2, not shown). The material is led below the chamber 50, Fig. 3, where it is broken up by the abrasive blast, the resultant granules being raised by an elevator 92, while the rods 20 are discharged over a screen 88. The elevated material enters a separator 94, Fig. 1, where an air current deflects the reconditioned sand into an outlet 106, metal shot, which acts as the blasting medium being continuously re-cycled through a spout 102, with a magnetic drum separator 107 recovering any shot deflected towards the outlet 106. Fine material from the screen 40, including blast material cycling through the chamber 18, is raised by an elevator 46 into separating means 54, an air curtain supplied through an inlet 56 deflecting fine material through a conduit 64, while coarser material is deflected through polyurethane crushing rollers 66, along with the blasting material. Crushed material is deflected into a hopper 76 along with the material from the conduit 64, and flows through a conduit 78 to the blasting chamber 50, while the blasting material returns through a spout 72 to the throwing wheels 28. In a modification, Fig. 5 (not shown), material from the conduit 78 may be incorporated into the blast in the chamber 50, and the oscillating conveyer section below the blast chamber 50 may be stepped, Fig. 6, to counteract the tendency of the blast to drive material upstream. Alternatively, Figs. 7 and 8 (not shown), the material from the stripping chamber may be fed directly through a blasting chamber (138), elevator (134) and separating system (136), and in-addition, a second blasting chamber 156, Fig. 9, may be provided for increasing the scouring effect exerted on the recovered sand. The recovered sand may be fed through a separate scouring apparatus, Fig. 13, including a wheel 168 which throws the particles against plates 174, 176. Further, Fig. 17 (not shown), the recovered sand may be fed through a series of blasting wheels (198)-(202).

Abstract: 571,806. Toothed gearing. BIRMING- HAM SMALL ARMS CO., Ltd., and PERRY, C. A. Jan. 24, 1944, No. 1272. [Class 80 (ii)] [Also in Group XXI] A gun is elevated or trained by manuallyoperated mechanism incorporating a planetary train of gears and a lost-motion coupling, the arrangement being such that when the parts of the coupling are not in engagement the gear train is operative and produces a relatively slow movement of the gun, while when the lost motion is taken up, the gear train is ineffective and a direct coupling between the manual mechanism and gun is provided. In the construction shown, the cradle 1 of the gun is trunnioned in a bracket 7 formed with a spigot 10 which enters the gun support. The cradle is formed with a rack 3, and with this rack meshes an external ring of teeth 11 on a sleeve 9 rotatably mounted in the bracket. Within the sleeve 9 is a shaft 12 connected to the stem 15 of an elevating hand wheel 17, the stem being formed with a projection 19 adapted, by engaging with a projection 21 on the sleeve 9, to provide a direct drive between the hand wheel and the sleeve 9. In bracket 7 is also mounted a spring-loaded friction housing 23 carrying pinions 25, 29, the pinion 25 meshing with a pinion 27 on shaft 12 and also with the pinion 29, and the pinion 29 meshing with internal teeth 31 of sleeve 9. When the projections 19, 21 are out of engagement, the housing 23 is frictionally prevented from rotating and the pinions 25, 29 provide a reduction gear between the hand wheel and sleeve 9. With projections 19, 21 in contact, the sleeve and housing rotate as a unit. The sleeve may be locked in any adjusted position by a track brake shoe 33 pivoted at 35 and actuated by cam 39.

Title: Improvements in or relating to diaphragms for use with x-ray apparatus
Inventor: TILLING BASIL BOYLAND
IPC: G21K1/04
Filed: 1959-01-14
Abstract: 913,871. X-ray apparatus. GENERAL ELECTRIC CO. Ltd. Jan. 1, 1960 [Jan. 14, 1959], No. 1373/59. Class 98 (1). [Also in Group XXXVI] A diaphragm for X-ray apparatus is operated by electrical power means, which means is controlled by the balance point of one or more bridge networks to determine the diaphragm setting. The diaphragm (not shown) is in the usual form of two pairs of movable shutters, defining between them a rectangular aperture. They are operated by a reversible motor M. The bridge consists of two potentiometers 1 and 2 fed from a supply 3. The contact on 1 moves in synchronization with the shutters, while the contact on 2 is adjustable by hand. Between the contacts is connected a transistor amplifier circuit fed from a supply 5, 6; transistors 8 and 9 are cascaded to cause movement of motor M in one sense, and 10, 11 to cause movement in the opposite sense. In operation, the contact on potentiometer 2 is moved, which causes an outof-balance condition in the bridge circuit, thus rendering one pair of transistors more conducting than the other. This operates the motor to move the shutters, which at the same time moves the contact on potentiometer 1 till balance is restored, when the motor is de-energized. The control for moving the contact on 2 may be of such form as to give an indication of the degree of opening of the diaphragm. A rheostat 12 in series with potentiometer 2 can be varied so as to confine the X-ray beam within a safe margin of the screen size. In an alternative arrangement, the motor can be a reversible self-excited D.C. motor, and the transistor circuit replaced by a polarized relay connected between the movable contacts on the two potentiometers.

Title: Methods of reclaiming asphalt
Inventor: ROSTLER FRITZ S
IPC: C10C3/00
Filed: 1962-01-17
Abstract: Weathered asphalt, which may be in the form of a weathered asphaltic pavement containing asphalt and aggregate or oxidized asphalt, is reclaimed by applying an aqueous cationic or balanced emulsion of a specified type of petroleum fraction free from asphaltenes and containing 20-85% of a paraffin fraction, the residuum being unsaturated hydrocarbons and nitrogen bases. Various suitable petroleum fractions within the range specified above are disclosed. Preferably the paraffinic fraction should have a flash-point above 350 DEG  F. and the emulsion should contain a surface-active agent. The amount of emulsion added should be sufficient to penetrate the asphalt but insufficient to produce a free oil phase.  The emulsifier may be cationic or a mixture of cationic and anionic components, i.e. a "balanced" emulsifier; fatty quaternary ammonium salts (e.g. cetyl - pyridinium chloride), aliphatic fatty amines, fatty substituted aromatic amines, dodecyl phenol polyethoxyethanol and amidoamino-amine salts of lower fatty acids are specified components. A mixed cationic (0.5-1.5% by weight) nonionic (0.5-2.0% by weight) emulsification system is preferred which is spread, e.g. by spraying, in amounts 0.05 to 0.5 gallons per sq. yd. per inch depth of comminuted pavement.  Weathered asphalt compositions containing less than 10% paraffinic fractions are treated with a petroleum fraction to bring the paraffinic content above 10%. Penetration values may be used as a guide to the state of the weathered asphalt.  Thus an asphalt having a low penetration value in the range 30-300 is treated to give a penetration value substantially higher in the range 30-300. A method of analysing weathered asphalt compositions and the mode of reclaiming thereafter is disclosed together with a number of suitable treatment fractions which are described in association with various standard specifications controlling uses of asphalt.  The resistance of asphaltic pavements to weathering may be enhanced by spreading the emulsion in amounts 0.05-0.15 gal. per sq. yd. per in. depth, at a time not later than the first development of hair cracks.
