Title: Improvements in or relating to the separation of parts
Inventor: BONIFACE FREDERICK GEORGE
IPC: B03C1/06
Filed: 1964-01-15
Abstract: Ferrous metala workpieces, contained in a vibratory container with a mass of processing media, e.g. loose chips of rock, for finishing the workpieces by abrasive action, are separated from the media by means of a magnetic separator mounted above the surface of the media so as to act on the top layer of the media and extract workpieces which are brought into the magnetic field by circulation of the media about a generally horizontal axis as a result of the vibrations imparted to the container.  The separator may be in the form of a magnetic drum 6; Fig. 1 (not shown), journalled at one end of a pair of arms 7 which at their other end support an electric motor 8 for rotatining the drum through a belt 9.  The arms are pivotably and slidably mounted on a bar 11 to allow for swinging of the drum towards or away from its working position and for traversing of the drum by means of a drive chain 12 suitably coupled to the arms.  A shoot 14 discharges the workpieces 4 into a hopper 15 surrounded by a demagnetizing coil 16.  In a modification, Fig. 3 (not shown), the arms 7 are secured to ball bearings 17 mounted on a screwed rod 18 rotated in alternate directions by a motor 19.  In another modification, the magnetic drum extends the full length of the container so that no traversing means are required.  In a further modification, the magnetic drum is mounted at one end of the container transversely thereof.  In Fig. 6 (not shown), the separator comprises a magnetic pully 21, a non-magnetic pulley 22, a jockey pully 23 and a belt 24 for conveing the workpieces from the pulley 22 for discharge after passing through a demagnetizing coil 26.  A magnet 17 assists in retaining the workpieces on the belt.  In a last embodiment, the separator takes the form of an electromagnet arranged to be selectively energized to extract the workpieces and mounted on slides or runners to allow it to be moved clear of the container when it is de-energized to release the workpieces.  A guiding tube of rounded triangular cross-section may be disposed along the axis of the carrier in any of the embodiments described to assist in the circulation of the media in an annular path.

Title: Method and apparatus for the preparation of coffee
IPC: A47J31/24
Filed: 1960-01-19
Abstract: 870,477. Valves. RENEKA S.A. Jan. 19, 1960, No. 1823/60. Class 135. [Also in Group VI] Coffee-making apparatus comprises a cylinder 1 with a valve controlled inlet 10 through which hot water may be fed regardless of the position -of an expulsion piston 2 to which pressure can be applied. As shown, a control piston 4 operating in a pressure cylinder 5 is connected by a rod 3 to piston 2 beneath which is secured a cup-shaped member 9 carrying a strainer 7 for ground coffee. The pipe 10 is controlled by a valve 11 normally urged closed by a spring 12. The apparatus is started by pushing a button 13 to move a shaft 14 until a spring-loaded ball 24 in a cavity therein engages in a cavity 26 to hold the shaft 14 in this position. The shaft end 14a meanwhile engages a lever 15 to rotate a cam-shaft 16 and hence a cam 16a to open, through plate. 17 and stem 18, valve 11 and to hold it open to allow hot water to enter cylinder 1. The hot water flows in between piston 2 and a sprinkler 21 and is cooled a little before it passes through sprinkler 21 on to coffee 6. The water pressure is sufficient to raise piston 2, and hence piston 4, but is insufficient to force the water through the coffee 6. Cylinder 5 has a combined inlet and outlet pipe leading to a three-way union 22 whose arms are connected to a mains water supply inlet and to a discharge pipe controlled respectively by valves 31, 32 operated by cams on shaft 16. When ball 24 enters cavity 26, it pushes a ball 27 against a rod 28 so that its end engages a slot 29 in connecting rod 3. Slot 29 diminishes in depth towards the lower end so that, as the pistons rise, rod 28 is gradually pushed out until shaft 14 is released and pushed back to its original position by the action of a spring 43 on shaft 16. This rotation of shaft 16 opens the mains supply valve 31 and cold water enters cylinder 5, thus forcing the pistons down and forcing the hot water through coffee 6, strainer 7 and outlets 32, 32a. A second similar arrangement is provided having a push-button 33 and a slot 40 corresponding to slot 29 but of different length so that a different quantity of coffee can be made. Operation may be halted at any time by depressing a rod 41 or 42 which engages ball 27 or ball 38 to release press-button 13 or 33.

Abstract: 178,524. Crompton & Co., Ltd., A. G. :E. Electric Motors, Ltd., Jones, W. F., and Waters, H. C. Jan. 12, 1921. Lighting and heating systems; systems of charging and discharging galvanic batteries; starting prime-movers, dynamo-electric machines and control circuits for.-An electric supply svstem comprising a petrol engine and a dynamo-electric machine adapted to operate as a starting-motor and as a generator, is provided with voltage balance relay and a control relay having two windings which are open-circuited when the engine is being started. To start the system, a knob G, Fig. 1, is depressed to open the circuit of the relays V, X at the switch H, to render the ignition system operative by lowering the switch K, to energize the starting-relay T through the switch J, and to place the armature L, slidably mounted on the spindle E, in contact with a holdon magnet M. The operation of the relay T places the armature A and series field winding B of the dynamo-electric machine across the battery O, and the machine runs as a series motor to start the engine. When the engine starts the knob G is released and the switch J is opened to deenergize the relay T, thereby disconnecting the machine from the batterv, the switch H is closed, and the switch K is held open since the magnet M in the shunt field circuit C of the machine or in a separate circuit is energized. The balanced voltage relay V comprises a coil v<1> connected across the dynamo, a coil v<2> connected across the battery, a pivoted armature w, and an adjustable weight w<1>. When the voltage of the dynamo rises above that of the battery to a determined extent, the relay V operates to close at its contacts W the circuit of the switch U, thereby connecting the dynamo to the battery 0 through the winding x of a relay X and connecting the coil x<1> of the relav X across the dynamo at the contacts u, u<1>. When the current in the charging-circuit is reduced to a predetermined value, the relay X operates to short-circuit at the contact Y the hold-on magnet M and the switch K is closed to stop the engine. A switch Z operated by the armature of the relay X is operated to break the circuit of the coil v<1> of the relay V and the switch U is de-energized to disconnect the dynamo from the battery. When it is not desired to stop the engine, the contact Y of the relay X is omitted or a switch is inserted in the circuit of the switch K to prevent the switch from rendering the ignition circuit inoperative.
