Title: Method of synchronising press or like production lines
Inventor: GRIESINGER KARL
IPC: H02P5/50
Filed: 1967-08-31
Abstract: 1,138,034. Automatic control of speed. L. SCHULER G.m.b.H. Aug.31, 1967 [Sept.23, 1966], No. 39908/67. Heading G3R. In a system for keeping one or more machines 1, e.g. presses, in a production line in synchronism with a master machine or reference 2 by adjustment of its speed in a correcting sense when the phase deviation, detected at 5, reaches a first predetermined value, a further and smaller adjustment is made in the opposite sense when the deviation has dropped to a second, lower, value. Each machine is driven by a three phase commutator motor whose brushes are moved by a servomotor 11, which is energized for a finite time by a relay 9 (for positive errors) when a phase error great enough to close a relay 6 has persisted for a time determined by a delay switch 7. After a further time, determined by 12, the relay 6 is "tested" at 13 and if it is still energized (i.e. the error has persisted) a further adjustment in the same direction is made by relay 9. The relay 6 drops out when the phase error has dropped to half, when after a time 14 a relay 16 is closed for a short time to energize the servomotor 11 in the opposite direction. A similar arrangement corrects for negative errors, via relay 18, and the time intervals can be different from those pertaining to positive errors. It is stated that the adjustment made when the phase error has decreased may be in two stages, the second smaller than the first, and that the correcting servomotor may be run for a time proportional to the speed or phase deviation.

Title: Improvements in or relating to ion separation
Inventor: WISFELD WERNER
IPC: B01D15/04
Filed: 1965-09-23
Abstract: Heavy metal ions and alkali metal ions in neutral or acid solution are separated by loading a cation exchanger up to equilibrium (i.e. until the effluent has the same concentration as the feed) and eluting the alkali metal ions with dilute acid.  The exchangers is then loaded again and the process repeated.  During loading, the effluent is recycled with the feed.  Elution is continued until the effluent shows increased concentration of heavy metal ions.  The effluent (containing alkali metal ions and some heavy metal ions) is fed to a second cation exchanger in the H-form, which initially takes up all the metal ions and provides a dilute acid effluent which is fed back to elute the first exchanger; after breakthrough of alkali metal ions, the effluent is drawn off and the alkali metal salts recovered; at breakthrough of heavy metal ions, the feed is stopped, dilute acid is passed in (to remove alkali metal ions only) and the effluent added to the effluent from the first exchanger; finally the exchanger is regenerated with concentrated acid, giving an effluent (containing heavy metal ions) which is recycled as feed to the first exchanger, or may be collected in two fractions, the second of which is passed over the second exchanger with the dilute acid in the next cycle.  The exchangers should be highly acidic, preferably polystyrol base cross-linked with more than 10% divinyl benzene.  The eluting acid may be H2SO4.  The process may be operated in cycles, using 2 columns of the first exchanger, and 2 or 3 of the second.  The separation may be applied to solutions containing Zn and Na from the cellulose-xanthogenate process, and to Cu solutions from one leaching.ALSO:Heavy metal ions in neutral or acid solutions, which also contain alkali-metal ions, are loaded on to a strongly acid cation-exchanger until the concentration of ions in the effluent is equal to the concentration in the feed.  The alkali-metal ions are then discharged in the first stages of elution with a weak concentration of acid.

Title: Improvements in or relating to circuits for starting and operating electric discharge lamps
Inventor: DUNTHORNE DONALD
IPC: H05B41/232
Filed: 1958-12-18
Abstract: 895,970. Supply systems for space discharge apparatus. GENERAL ELECTRIC CO. Ltd. Dec. 3, 1959 [Dec. 18, 1958], No. 40905/58. Class 38 (4). A starting and operating circuit for two or more electric discharge lamps includes two branches connected in parallel between the input terminals 1, 2 of a D.C. supply for the discharge currents, each branch comprising a ballast resistor 4 or 8, a choke coil 3 or 7 and lamps such as L1 to L8 or L9 to L16, the choke coils 3, 7 being wound on a common magnetic core in opposite senses so that the discharge currents in the two branches produce equal and opposite magnetic fluxes in the core, and starting terminals 14, 17 to which an alternating voltage to facilitate starting can be applied. In operation, and as applied to a train lighting installation, the input terminals 1 and 2 are supplied from the D.C. track circuit and the A.C. starting terminals 14, 17 are supplied from a power transistor oscillator 13 fed from the train's batteries and provided with a further output terminal 15. Transformers 19, only two of which are shown, each having three secondary windings 20, 21, 22, provide electrode heating current for the lamps and are connected in parallel between the terminals 14, 15 with a resistor 23, of negative temperature coefficient of resistance, in circuit to limit the heating current at starting. A starting voltage comprising the direct voltage across terminals 1 and 2 together with the alternating voltage across terminals 14 and 17 appears across the lamps L1 to L8, and by way of the coupled coils 3 and 7, across the lamps L9 and L10. When the lamps have started the high inductance of the coils 3 and 7, resulting from the fact that the discharge currents flowing through them produce no net magnetizing flux, prevents current passing from the A.C. terminals 14 and 17 to the direct current source, and the amount of this current passing through the lamps is limited by a capacitor 18 connected between terminal 17 and a terminal 16 of the supply 13.

Title: Brakes
IPC: F16D65/84
Filed: 1971-09-03
Abstract: 1360848 Cooling of brakes SOC ANON FRANCAISE DU FERODO 3 Sept 1971 [4 Sept 1970] 41249/71 Heading F2E A brake having a rotatable component, e.g. a disc, has braking means, a heat-collecting shoe, and means for controlling the shoe to urge the shoe towards the rotatable component, the control means being different from control means of the braking means. Two such opposed heat-collecting shoes may be of aluminium, aluminium alloy or a composite material containing aluminium, e.g. alumina-ceramic, or similar materials employing copper or iron, and are supported in a fixed or floating caliper forward of the brake shoes in the direction of rotation. The shoes are held close to or permanently against the disc by magnets or loaded springs, or are held intermittently against the disc by either of two control devices described below: (a) Fig. 7 shows an electro-hydraulic control wherein, when the brakes are applied, fluid flows through an inlet 31 from the brake circuit to outlet 32 and then to the heat-collecting shoes until a pressure build-up closes valve 33, the shoes being applied. Upon valve closure, a rod 35 closes a contact 40B to excite an electromagnet 40 which holds the rod and valve in the downward position. The rod 35 also moves a lever 46 which releases a bellows 42 which expands slowly due to a small aperture inlet 56. After a predetermined time, the bellows expansion causes a finger 45 to break the electromagnet circuit, thus open the valve, and release the shoes. (b) Fig. 8 shows an hydraulic control circuit having an inlet 71 from the brake circuit, via a pressure restrictor 70 as in (a) above, a oneway valve 73 and an outlet 72 to the shoes. A variable capacity chamber 75 is controlled by a spring loaded piston 76 with a bleed by-pass 78 to a leakage return pipe-line. The predetermined time of shoe application is controlled by the fluid leakage past the piston 76 until it abuts a shoulder 761. The shoes may be solid, or have passageways for coolant flow, e.g. water. The shoes have a coefficient of friction of less than 0-3, heat conductivity greater than 0À2 cal. cm. see.‹ C., and a specific heat greater than 0À4 cal./‹ C./cm.<SP>3</SP> The heat-collecting shoes and their caliper may be movable with respect to the disc, and the shoes may also be used as a parking brake.
