Title: Improvements in or relating to processes for separating mixtures of solid particles of different porosities
IPC: B03B5/30
Filed: 1955-06-28
Abstract: Particles of different porosities and the same or practically the same skeletal densities are separated by filling the pores of the particles with gas before separation and contacting the particles with the separating liquid for a sufficiently short length of time to allow the pores to remain filled with the gas. A cyclone separator is used and a true liquid or a suspension may be used for the separating liquid.  The solid particles are introduced to the cyclone by the gas to be used to fill the pores which may be at 1 to 5 atmospheres pressure.  Multi-cyclones are preferably used.  In an example two cyclones having a diameter of 1 cm. and a length 3 and 6 cms. respectively, are used.

IPC: B25D9/12
Filed: 1970-04-20
Abstract: 1302759 Rock drills INGERSOLL-RAND CO 20 April 1970 [22 May 1969] 18799/70 Heading B3C [Also in Division B4] In a percussive tool including a tool bit 15, and a hammer piston 10 reciprocable in a cylinder liquid, e.g. oil, is supplied alternately to chambers 8a, 8b (Fig. 3) to effect reciprocation of the piston and via each chamber to a respective accumulator 90, 91. The supply of liquid is controlled by grooves in the piston coacting with ports in the cylinder during reciprocation of the former. Liquid under pressure initially passes into a tank 100, and, with the hammer piston in the position illustrated in Fig. 2, passes via pipe 111, and grooves 68 into the chamber 8a and acts on shoulder 11a of the piston to urge the piston on a return stroke. At the same time liquid passes from chamber 8a via annular passage 54 and bore 94 into the accumulator 90, and chamber 8b communicates with an outlet pipe 121, which leads into an outlet tank (101) (Fig. 1, not shown), via grooves 66 and annular passage 53. As the piston moves on its return stroke, communication between inlet pipe 111 and chamber 8a, and between chamber 8b and outlet pipe 121 is terminated. Energy of the liquid accumulator 90 is then released into chamber 8a to continue the piston return, and liquid in chamber 8b will be compressed and forced into accumulator 91. As the piston continues its return motion grooves 65 will open communication between liquid inlet pipe 110 and chamber 8b so that the chamber 8b and accumulator 91 will be charged with liquid. Simultaneously chamber 8a communicates with the outlet pipe 121 via grooves 67. Return motion of the piston is then terminated and a drive stroke commences. The liquid stored in accumulator 91 will effect continuation of the piston's drive stroke when the liquid supply to chamber 8b is terminated. Communication between the inlet pipe 111 and chamber 8a via grooves 68 is effected before the piston impacts the tool bit 15. The force acting on the piston on its drive stroke is supplemented by air or hydraulic fluid compressed in chamber 131 at the end of the return stroke. A motor 20 via gearing and chuck 27 effects rotation of the bit which receives air for blowing cuttings out of a bore hole.

Abstract: 1427922 Food additives UNILEVER LTD 1 March 1973 [3 March 1972 24 April 1972] 9976/72 and 18813/72 Heading A2B An edible composition for addition to foods for humans or animals comprises a stabilised additive, for example, a flavour, enzyme, vitamin amino acid or gassing agent, which is polar or water-soluble and hence tends to be leached out during cooking, or is non- polar and volatile and hence difficult to retain. The additive is stabilized by being dispersed in a paste comprising an edible oily material and a finely divided filler consisting of an edible salt of a fatty acid. The paste is prepared in particulate form, preferably as spheres of diameter 0.3 to 5 mms. These may be coated with filler or filler plus oily material. The oily material may be mineral or vegetable waxes, etherified sugars, ester waxes or a silicone oil or grease, but edible triglycerides are preferred. The filler is a water-repellant oil compatible solid material; calcium stearate is preferred but calcium palmitate or oleate or aluminium stearate, palmitate or oleate are satisfactory. The product may be prepared by forming a paste of the components, extruding, dividing into segments which are formed into spheres and coating the spheres with filler at a temperature near to or above the melting point of the fat or oil. The stabilized additives may be incorporated in reformed meats, sausages meat balls, pasta products, animal foods &c. Additive release occurs on cooking or chewing.

Abstract: 1494901 Character recognition systems; digital calculators SOC SUISSE POUR L'INDUSTRIE HORLOGERE MANAGEMENT SERVICES SA 21 April 1975 [30 April 1974] 18902/74 Headings G4R and G4A Characters are written by a conductive stylus on a surface which is divided into conductive zones. The zones feed logic circuitry which develops a binary signal indicative of the order in which the zones were contacted and which decodes the signal to identify the character. The surface may form part of a digital wristwatch which incorporates a calculator, the identified character being displayed and controlling the calculator. The surface may be divided into 4 conductive zones 1-4 as shown in Fig. 2 or may carry a number of conductive strips (Fig. 5, not shown). When a signal is injected into a zone, e.g. by contact with a stylus connected to the watch case by an electrical path through the body of the user, a corresponding bi-stable M1-M4 is set and subsequently a corresponding 2-bit signal is fed to a shift register R. When the next zone is contacted the corresponding bi-stable is set as before, and the previously set bi-stable is reset via a gate 01-04. A short time after the first zone was contacted, during which period the whole character has been assumed to be written, the signal in register R is read to decoder D which gives an output on a lead corresponding to the character written, or corresponding to a function selected by contacting a single zone. The character or function is displayed and fed to the calculator circuit. If the character is incorrectly written an error signal is displayed or the display flashes repeatedly.

Abstract: 237,915. Oil Engine Development Co., (Assignees of Cummins, C. L.). July 30, 1924, [Convention date]. Cylinders receiving liquid fuel.-Fuel is supplied during the suction stroke of the working piston 7 through a valve 14 to an annular space 20, where it is highly heated, and whence it passes through grooves 19 to a central space 17 below a plunger 11. The central space 17 communicates with the working cylinder through fine orifices 21. While the fuel is being supplied to the space 17, the plunger 11 is slowly retracted so as to prevent drip through the orifices 21. During the compression stroke, the fuel is mixed with and vaporized by hot air from the cylinder entering through the orifices 21, and at the beginning of the working stroke the resulting mixture of vaporized fuel and air is injected into the cylinder by the descent of the plunger 11. The plunger has a conical end which fits within a corresponding seating when the plunger is fully depressed, so as to ensure the complete evacuation of the air and fuel from the space below the plunger. In a modified construction, the plunger 11 is formed with a concave spherical or conical end,. and the lower face of the chamber is provided with a corresponding conical or spherical projection, through a central orifice in which the fuel is admitted from the valve 14. The spraying orifices 21 are formed in the periphery of the lower end of the cylinder within which the plunger works, and are preferably tangential to this cylinder. The fuel may be supplied through the valve 14 either by gravity or by a pump.
