Filed: 1950-01-16
Abstract: 689,840. Lubricating. PAGE, V. J. April 16, 1951 [Jan. 16, 1950], No. 1034/50. Class 12 (iii). A lubricator for a pneumatic tool or other appliance operates when the pressure in the tool is cut off or lowered beyond a predetermined amount, and comprises a reservoir 1, a duct 8 having one end in communication with an air passage 6 in the tool and the other end 9 open in the reservoir, and an air vent 12 in the duct above a permissible oil level in the reservoir. In operation, air under pressure enters through vent 12 into the space 13 to equalize the pressure inside and outside the reservoir. When the air supply is cut off or lowered beyond a pre-arranged amount the air in the reservoir exerts pressure on the oil to force some of it into the tool through a porous plug 14 of felt &c. The plug may be one of a number each having different degrees of liquid permeability. In a modification, the reservoir is vertically instead of horizontally mounted on the tool, and the duct is of inverted U-shape with the vent in the bend of the U.

Title: An improved advertising device
IPC: G09F11/26
Filed: 1933-01-12
Abstract: 392,128. Changing-signs. FOWLER'S AUTOMATIC ADVERTISING, Ltd., 43, High Street, Auckland, New Zealand. Jan. 12, 1933, No. 1124. Convention date, Feb. 20, 1932. [Class 3 (i).] An endless display band 3 accumulating in folds is moved at each pull of a paper roll 11 by mechanism which ensures that only one new complete section shall be brought into view at each pull. The paper roll 11 is fixedly mounted in a frame 13 swinging about stub shafts 14 and connected through a one-way ball clutch to a gear wheel 18 meshing through an idle wheel 19 with a wheel 20 on a banddriving roller 5. A pin 30, Fig. 4, on a spring-pressed bell-crank 29 engages a catch 28 on a disc 27 fixed to the roller 5 to limit the rotation of the roller 5 to one revolution at each pull of the paper 11. A projection 31 on the shaft 14 normally holds the bell-crank 29 raised to allow the roller 5 to start. The projection 31 bears against a spring 33 during the latter part of its rotation to slow down the roller 5. A serrated edge 13a on the frame 13 facilitates the tearing off of the paper 11, and a spiral spring subsequently returns the frame 13 to its original position, the clutch allowing this to take place without turning the wheel 18. The roller 5 has teeth 5a to engage perforations in the band 3, and a spring- pressed jockey roller 9 ensures contact. The paper roll 11 is mounted on a diamondsectioned core 11 a, which is removably held in the frame 13 by swinging recessed plates 22, Fig. 9, and spring-pressed recessed plates 23 sliding on pins 24.

Title: Improvements relating to electro-hydraulic control systems
Inventor: FAKE GEORGE
IPC: G05B11/50
Filed: 1957-01-11
Abstract: 875,815. Automatic speed and position control systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 22, 1958 [Jan. 11, 1957], No. 1163/57. Class 38 (4). [Also in Groups XXIX and XXXVIII] In an electro-hydraulic control system the delivery of an hydraulic pump is controlled by an electro-strictive device responsive to an electric voltage representing the difference between a reference voltage and a voltage proportional to the speed of an hydraulic motor driven by the pump or dependent on the position of a movable member driven by the motor. As shown, an hydraulic pump 1, driven by a constant-speed electric motor 3, supplies fluid under pressure to an hydraulic motor 2 through a balanced-piston valve 17 in which the position of a piston 18, controlling the flow from the pump, is determined by varying the pressure across restrictions 15, 16 by altering the flow from nozzles 13, 14. The output from a tachogenerator 7 is compared with a reference voltage obtained from a tapping 8 of a potentiometer 13 at the input to an amplifier 9. The output of the amplifier is applied to outer electrodes 10 of an electro-strictive member 11 comprising two plates of barium titanate separated by a control electrode at zero potential. Under the amplified difference voltage one plate expands while the other contracts causing the member to bend and vary the flow from the nozzles 13, 14 to cause a displacement of the piston 18 to vary the flow from the pump 1 so as to maintain the speed of the motor 2 constant. In a modification, a tool of an automatic machine tool is maintained in a desired position by positioning the tool by the hydraulic motor 2 and energizing the electrostrictive member 11 by the difference between a reference voltage and the output voltage of a displacement transducer connected to the tool.

Abstract: Azo dyes are made on the fibre by coupling a diazotized unsulphonated o - aminoarylcarboxylic acid ester with an arylide derived from a b -ketomonocarboxylic acid (2 mols.) and a diamine of the diphenyl series (1 mol.).  Fast greenish-yellow to orange dyeings are obtained.  In an example, cotton is impregnated with diacetoacetyl-o : o<1>-tolidine and developed with diazotized 2-aminobenzoic acid ethyl or methyl ester or the 4- or 5-chloro derivative of the latter. Specification 210,217, [Class 2 (iii)], is referred to.  The Specification as open to inspection under Sect. 91 comprises the manufacture of unsulphonated azo dyes in substance, on a substratum or on the fibre by coupling an arylide of a carboxylic acid, which is capable of being coupled owing to the presence of two --CO.CH2-- groups with the above diazo components.  In an example, the condensation product from 1-(3<1>-carboxyphenyl)-3-methyl-5-pyrazolone (2 mols.) and benzidine (1 mol.) is coupled with diazotized 2-aminobenzoic acid ethyl ester. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,123,471. Control of D.C. motors. MULLARD Ltd. 26 Sept., 1966 [11 Jan., 1966], No. 1231/66. Heading H2J. [Also in Division G3] A series motor 1 is supplied from A.C. terminals 3 through thyristor 4. When the speed of the motor tends to deviate from the value set by adjustment of potentiometer 15, the smoothed and rectified voltage derived from tachometer-coil 17 changes to alter the potential applied to the base of transistor 8. The rate of charging of capacitor 9 is thus varied together with the period at which bi-stable trigger circuit 7 changes-over and supplies a conduction pulse to the gate of thyristor 4. The speed of the motor thus reverts to its previous value.

Abstract: 621,375. Phase changing. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). Jan. 19, 1945, No. 1604. [Class 38 (ii)] In a phase converter interconnecting single and polyphase circuits, a transformer has n sets of inductively coupled windings, n windings, one from each set being connected in series across a single-phase circuit and n other windings, one from each set being connected symetrically to the polyphase circuit, the turns ratios being so arranged, and reactances being so connected to the polyphase windings that the polyphase load is balanced for a given load on the single-phase circuit. Three-phase, similar, input, transformer windings 1, 2, 3 are meshconnected, and the corresponding output windings 11, 21, 3<SP>1</SP> of which 3<SP>1</SP> has only half the turns of equal windings 1<SP>1</SP>, 2<SP>1</SP>, are connected in series with 3<SP>1</SP> reversed to a single-phase circuit 4. To equalize the currents of inputs phases 1, 2 with the current in phase 3, and to bring them into phase with their respective line voltages, assuming unity P.F. of the single-phase load, capacitor 7 and inductance 6 are connected across phases 1, 2, respectively. The winding 1 may be wound as an auto-transformer to supply a higher voltage to capacitor 7, Fig. 3 (not shown), while to provide inductance in phase 2 this may be wound on a core having an air-gap. A suitable three-phase core is described, Fig. 4 (not shown), of F-shaped stampings placed opposite each other, with a variable air-gap between the two projections forming the middle leg. With variation in load the values of capacitor 7 and inductance 6 must be suitably altered to maintain the supply in balance, while with variation in power factor, the turns ratio must be altered in addition. The transformer works equally well supplying a three-phase load from a single-phase supply.
