Abstract: 686,984. Discharging ball &c. mills. ACHESON COLLOIDS, Ltd. June 21, 1950 [June 24, 1949], No. 16803/49. Class 59 [Also in Group XXX] A method of discharging or unloading a batch of treated material from a ball or rod mill in motion comprises withdrawing the material pneumatically (preferably by suction) radially from the interior of the mill through the cylindrical wall thereof and conveying it along an enclosed path externally of the mill interior, part of which path rotates with the mill and part of which is stationary, into a suitable receiver which is vented (preferably to an evacuating source such as a centrifugal fan or a pump) through an air pervious filter, cyclone or other separator. To manholes 3 of a ball mill are detachably secured, after grinding has been completed, boxes 4 communicating with. the interior of the mill through grids 5 and being connected by pipes 6 to a hollow trunnion 2. The pipes 6 may be built into the wall of the mill. A hollow cylindrical plug 12 closed at one end, its inner end, and formed with a port 16 is inserted into the hollow trunnion 2 and is secured to the stationary trunnion-bearing member. The open end of the plug 12 is connected by a pipe 10 to receiving vessel 11 in connection, through an, air-pervious filter 84, with a suction device 17. The arrangement is such that as the mill is rotated air and comminuted material is drawn through a grid 5, when a box 4 is in its lower position, through the box 4, its associated pipe 6, the port 16 in the plug 12 to the receiving vessel 11 where powder falls into a container 80. Air is allowed to enter the mill through its other hollow trunnion 1. For a mill having a solid trunnion 50, Fig. 9, the pipes 6 are connected to a bore 51 in the trunnion heading to a stationary hollow member 52 secured to the bearing member and being in sealed connection with the trunnion, the member 52 then being connected to the suction and receiving device. The powder may be delivered to a vented mixer, the vent being connected, through a filter,. with a suction source. In normal grinding, operation the boxes 4 and pipes 6 are removed and manhole covers replaced, the ported hollow plug 12 replaced by a closing plug, and the other trunnion 1 closed. Alternatively, permanent boxes may be provided having a valve-member to close the grids when the mill is grinding. Warm air may be supplied to the mill. The mill may be charged by the means described in co-pending Specification 686,983, to which reference is made.

Filed: 1963-04-29
Abstract: 972,426. Fuel-ignition pumps. SULZER FRERES S.A. April 29, 1963 [May 25, 1962], No. 16810/63. Heading F1A. In a diesel engine fuel injection system comprising an injection pump 2 delivering to a valved injector via a pipe 7, pressure waves in pipe 7 produced at the end of the delivery stroke are damped by connecting pipe 7 to a chamber 30 via a valve 34 controlled by the pump such that valve 34 is closed during injection and opens when injection terminates. In the embodiment shown, valve 34 is actuated by the pump piston through rods 36, 37, the timing of actuation being determined by the setting of an eccentric 35. Damping is assisted by a spring-loaded piston 32 and a throttle 38. The quantity of fuel injected is regulated by the pump piston acting through rods 22 to open a suction valve 20 during delivery, according to the setting of an eccentric 21. Alternatively, suction valve 20 and damping valve 34 may be interconnected and actuated simultaneously through linkage 22, or the damping valve may be connected to the delivery valve so as to open when the delivery valve closes. In place of piston 32, chamber 30 may have an air cushion or be filled with fuel.

Title: Method of and apparatus for maintaining an ecological balance in a closed water system
IPC: A01K63/04
Filed: 1975-04-23
Abstract: 1495764 Biological water treatment P HAFSLUND and K HAGQUIST 23 April 1975 [25 April 1974] 16869/75 Heading C1C [Also in Divisions Al and B1] A closed water system, e.g. aquarium or swimming-pool, is maintained in ecological balance by passing the water through a layer 4 of material chosen according to the environment which is to be simulated, e.g. for a sea environment, sea-bed material is used. This layer 4 is supported on a perforated calcareous screening-plate 3 and it filters the water biochemically and converts nitrogenous waste to inorganic salts, any excess of which is removed in turn by green algae which are encouraged to grow by using lights 5. Thus no waste matter need be removed from the system. After passing through the material 4, some of the water then flows via a perforated pipe 9, through a heat exchanger coil 10 surrounded by a cooling medium 7, which is cooled by element 8, compressor 16 and radiator 17. The water may then pass around the radiator 17, depending on the watertemperature required in the tank 1. The water circulates either by slow mechanical pumps (not shown) or by introducing air, by a pump 13, into a chamber 12, thus raising the water into pipe 15 and aerating it, while this flow causes suction of water down through the material 4 and then up through a pipe 22 and into the pipe 15. Both methods for water circulation avoid mechanical destruction of plankton which further aids maintenance of an ecological balance. A panel 18 controls thermostats 19, 20, periodic switching of the lights 5 and provides automatic control means for the system. Several aquaria may be interconnected using level regulating pipes 23, so as to be served by a single master tank.

Abstract: 1,036,351. Radio receiving circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. April 23, 1964 [April 26, 1963], No. 16871/64. Heading H3Q. The invention relates to a television tuner of the type comprising a Lecher line 6 divided into sections 1-4, switching from one V.H.F. channel to another being effected by displacement of a short-circuiting contact 8 from one section to another and fine tuning being performed inductively by displacement of the contact 8 on a section. According to the invention, each of the sections 1-4 is connected in a first resonant circuit, comprising inductors 9-12 respectively, and capacitor 13, which in turn is connected to the oscillator valve 7 via a second resonant circuit comprising inductor 14 and capacitor 15; the inductance and capacitance of the first resonant circuit are made respectively smaller and greater than those of the second. Portion 5 of the Lecher line serves for continuous tuning on a U.H.F. band, inductor 14 acting as a choke for these frequencies. Automatic fine tuning may be effected by using as capacitor 15 a voltage variable capacitor diode. In a modification (Fig. 3, not shown) the tuning range so realised is equalized between the U.H.F. and V.H.F. bands by connecting line portion 5 to the anode of the valve via a series capacitor and shunting the end of the line with a further capacitor. These capacitors form with the valve capacities a bridge circuit which may be utilized to allow a variable capacitor, connected between the end of the line and earth, to be used for trimming the U.H.F. circuit without affecting the V.H.F. circuits.
