Patent GB-936076-A (GB)
Title: Improvements in and relating to means for determining angular displacement
Inventor: PYLE CLIFFORD MARTIN
IPC: H02P3/06
Filed: 1960-01-25
Abstract: 936,076. Control of A.C. motors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 18, 1961 [Jan. 25, 1960], No. 2656/60. Class 38 (3). A feed motor in a machine tool is caused to rotate a predetermined amount by coupling to it a D.C. tacho-generator GN connected to a saturable reactor Tr arranged to stop the motor when saturation is reached. It is stated that this will occur due to the integration of the tacho-generator voltage with respect to time, and hence the feed motor will move a constant amount regardless of its speed. The amount may be regulated either by adjusting the output of the tacho-generator by a field rheostat EPOT or by connecting it to the reactor Tr via a potentiometer. Alternatively, or in addition, the reactor winding W1 may be tapped. Upon saturation of the reactor a relay I 1  is operated by the resultant increase in current through the winding W1, either directly or after amplification ; to increase sensitivity the relay may have a separately energized premagnetizing winding I 2 . The reactor is reset after each operation by an additional winding W2. An embodiment is described (Fig. 7, not shown) in which the feed motor is that of a planing machine and comprises a three-phase induction motor. This is energized at the beginning of each working stroke of the planer and operation of the relay disconnects the motor windings from the A.C. supply and connects them either to a source of D.C. or to capacitors for braking purposes. A push-button enables an operator to repeat the feed cycle. Specification 665,380 is referred to.

Abstract: 379,974. Valve amplifying circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London. -(Assignees of Braden, R. A. ; 310, Plymouth Place, Merchantville, New Jersey, U.S.A.) Jan. 30, 1932, No. 2869. Convention date, Feb. 20, 1931. [Class 40 (v).] In order to correctthefrequency response characteristic of a moving coil loudspeaker 5 associ ated with a pentode output valve 1, a reactive impedance L is connected in the screen grid circuit of the amplifier. By this means the tendency of the pentode to emphasize the higher frequencies, due to its practically constant current output combined with increase of loud-speaker coil impedance with frequency, is obviated. The inductance L may be variable, constituting a tone control ; or a circuit comprising an inductance and condenser in parallel may be substituted for the inductance to reduce amplification at the resonant frequency, Fig. 3 (not shown).

Solids are separated by passing a stream of liquid of constant density with the solids in suspension therein, in constant volume per unit time and without deposition, down a chute from which the liquid is discharged in a lamellar stream, the position of the outlet of the chute relative to a series of baffles being movable in response to variations in the total weight of the suspended solids in the chute, so that, provided the concentration of solids is constant, such solids are separated or collected by the baffles according to their density. The chute 1 is pivoted at 2, the outlet end being suspended by tension spring means 4 so as to be movable relative to the baffles 3. Alternatively, compression springs or counterweights may be used instead of the tension spring means 4 and the pivot 2 may be located below the chute; or, the baffles may be variable in position or both baffles and chute; or the resistance of the spring 4 may itself be variable; or the position of the pivot 2 may be variable.

A continuous flow jetpropulsion engine comprising an open-ended pipe for the circulation of a gas according to a thermodynamic cycle, in which the gas is heated and it is only after expansion that the gas is compressed from the low to the high-pressure part of the cycle and is cooled during flow at the low pressure, has the gas flow circuit folded back on itself so that the gas after expansion is cooled by the gas flow at the high pressure before it is heated. Air entering the intake 2 of the casing 1 passes at constant velocity to the burners 21. During its passage, the air is heated by the exhaust gases of the turbine 4 passing through the tubes 6. After further heating by the burners 21, the air is expanded in the passage formed between the casing 1 and the division wall 20 and then passed through the guide blades 5 and turbine 4. The turbine exhaust gases pass through the tubes 6, which are provided with cooling ribs 7 to the throat 10 of a diffuser 11 where its pressure is again raised to atmospheric. A longitudinally adjustable bullet 13 allows the amount of diffusion to be controlled. The turbine 4 drives through a shaft 18 speed-reduction gearing and control gear contained in a housing 17. In a modification, the turbine 4 is omitted and a diffuser leading into the intake 2, provided.

Abstract: 779,617. Electrically heated coffee percolators &c. HOCHMAYR, F. Feb. 7, 1955, No. 3597/55. Class 129 [Also in Group XI] An electrically heated coffee or tea percolator comprises a steam boiler 1 and a water reservoir 2 connected by two ducts. 4, 5 leading through a fitting plate 3, a third duct 6 connecting duct 5 to a filter attachment on plate 3, and a valve plate 17 slidably mounted within the reservoir 2 on a bar 21 extending upwardly from plate 3, the plate 17 being biased by spring 22 away from the position where it closes ducts 4 and 5 and opens duct 6 and moved to such position by a manually operated lever device connected to the upper end of a tubular member 24 mounted on plate 17 and enclosing bar 21. Duct 5 extends nearly to the bottom of boiler 1 and duct 4 terminates just below the top. Duct 6 has bores 8 leading into a space 7 encircled by a connection 13 carrying parts of a bayonet joint whose complementary parts are on a filter fitting 14 having a coffee inset and an outlet 15. The lever device shown in Fig. 1 comprises a lever 26 pivoted at one end to a fixed rod 27, pivoted between its ends to tube 24 and engaged at its other end by a cam 30 secured to a hand lever 32. The stem 44 of a valve plate 11 spring pressed against a seating in duct 6 extends into duct 5. When lever 32 is pressed down it locks in position, packings 19, 18 on plate 17 close ducts 4 and 5 and a rod 42 extending from plate 17 into duct 5 engages stem 44 to lift plate 11 off seating 12. In operation, water is poured into reservoir 2 and hence through ducts 4 and 5 to boiler 1 and coffee or tea is placed in fitting 14. Heater 23 for boiler 1 is switched on and plate 17 is pressed down to the closed position by handle 32 so that steam generated in boiler 1 forces water out through ducts 5, 6 to the filter fitting 14 which delivers the coffee to a container beneath outlet 15. In a modification, Fig. 2 (not shown), lever 26 is replaced by a slide which is pivoted: to a link pivoted to plate 3 and has a cam edge to engage a transverse in on top of tube 24.
