A fuel briquette comprises a solid particulate fuel and as a binder a polymer of an olefinically unsaturated hydrocarbon or a mixture of two or more such polymers. Suitable polymers are polyethylene, polypropylene, polybutyrene, polystyrene, and copolymers of ethylene and propylene or butylene, propylene and butylene and butadiene and styrene. The polymer may be added to the fuel particles in the form of a fine powder, a solution or a suspension and in an amount up to 4% and preferably between 1 and 2% by weight of the fuel particles. The fuel briquetted preferably has a content of volatile matter less than 14% by weight and may suitably be a mixture of low- and mediumvolatile coals. The fuel particles are preferably smaller than 3 mm. and with 50% > 1 mm. and 90% > 0.1 mm. When the polymer is added to the fuel to be briquetted in particle form the mixture is heated to e.g. 220‹ C. when the polymer is polyethylene and then compressed. When the polymer is added to the fuel to be briquetted as a solution, e.g. polystyrene dissolved in benzene, toluene or xylene, the mixture is cold compressed and subsequently heated in a current of hot air to recover the solvent. Polystyrene may also be added to the fuel to be briquetted as a suspension, preferably after the fuel has been mixed with a quantity not exceeding 5% by weight of the fuel of a tar-oil distillate. The amount of tar-oil distillate preferably does not exceed 3% by weight of the fuel and may suitably be the fractions distilling at 140- 200‹ C. or 230-300‹ C.

Filed: 1961-02-20
Abstract: 938,598. Hydraulic apparatus. RHEINMETALL G.m.b.H. Feb. 20, 1961 [Feb. 26, 1960], No. 6214/61. Class 69 (2). Electro-hydraulic apparatus for converting rotary movement into linear movement comprises a piston 2, Fig. 1, reciprocatably mounted in a cylinder 1 and subjected to the pressure of an operating medium consisting of a metal or metal alloy, which is in a fluent condition at least during the operation of the apparatus. The operating medium may have a melting or solidifying point below about 200‹ C., the metal being brought into a liquid state when, or just before, the apparatus is operated. An electric motor 6 is connected by a telescopic rod 5, 5a to a pump 4 which passes the metal, when liquefied by the effect of a heating coil 15, through passages 19 from above to below the piston which is thus raised and, by means of a surface 20, at the same time raises the pump. The piston is lowered by gravity-springs or other restoring means and separates from the pump at the surface 20 to permit easy flow of the liquid metal from below to above the piston. The piston can be locked in a desired position by cooling and solidifying the metal. The heating means may be of the induction, resistance or eddy-current type and controlled by a thermostat. Oxidation of the liquid metal may be prevented by a protective gas. In another embodiment, the electric motor 25, Fig. 2, is connected to the cylinder 27 which has a heating coil 28 and a piston 34 having a seal 35 and connected by a ball-bearing 38 to a piston-rod 37. Rotation of the cylinder also effects rotation of the piston and the metal, when liquefied, is urged outwardly by centrifugal force to act beneath the piston which is thus urged upwardly in the cylinder. A storage chamber may rotate with the cylinder and flow therebetween be controlled by throttle means. The piston may be stopped in a desired position by providing control valves in the wall of the cylinder to direct the liquid metal back to the storage chamber. Rotation of the metal may be effected by a rotating or moving electric field operating on the metal. The piston may be replaced by a bellows, diaphragm or a similar element which may be connected by a stepping or stroke-multiplying mechanism to an output member. The apparatus may be disposed in a horizontal position. In another embodiment, the operating medium consists of a metal powder capable of flowing at room temperature and has liquid-like properties. The powder may consist of ferromagnetic particles.

Abstract: 1516074 Automatic control of gyroscopes BODENSEEWERK GERATETECHNIK GmbH 15 Feb 1977 [5 March 1976] 06279/77 Heading G3R The spin axis 14 of a gyro 12 is driven to and maintained in a north direction by a servomotor 36 which rotates a horizontal platform 10 on which the gyro is mounted. A pick-off and counter torquer produce a signal proportional to the size of the angular deviation from north, which is stored in digital form 22. A circuit 28 forms the corresponding inverse sine, and a sign signal from a second orthogonal gyro 16 resolves the ambiguity of whether the deviation is greater or less than 90 degrees. The actual deviation or a limit angle of 60 degrees, whichever is less, is entered into a counter 44 which is then counted down to zero by pulses from a generator 48 driven by the platform 10. The motor 36 then stops, and the process is repeated if there is still a deviation from north, e.g. if the initial deviation was greater than 60 degrees. In a second embodiment, Fig. 4 (not shown), the second gyro 16 is omitted, and the inverse sine ambiguity is not resolved, but if the correcting rotation has been made in the wrong direction, a comparator (105) detects this and the operation is repeated.
