Title: A polishing machine for the metal powders known as bronze colours
IPC: B41G1/00
Filed: 1929-10-22
Abstract: 341,562. Polishing metal powders. HARTSTOFF-METALL AKT.-GES., HAMETAG, 39, Kaiser Wilhelm Strasse, C÷penick, Berlin. Oct. 22, 1929, No. 32108. Convention date, Oct. 22, 1928. [Class 60.] Agitating articles for polishing by mutual rubbing. -A machine for polishing the metal powders known as bronze colours, and, if necessary, coating the particles with grease or oil, comprises a cylindrical drum provided with inlet and outlet openings for the powder, which is acted on by a rotary polishing-brush as the powder travels from the inlet to the outlet. As shown, powder from a container 18 passes through a charging-device 17 to an inlet 8 in the end wall 1 of a drum 3 made of ribbed or corrugated metal, and is subsequently discharged through an outlet 10 in the other end wall 2 into a receptacle 19. A rotary shaft 4 mounted in the walls 1, 2 carries arms 5 supporting one or more brushes 6, which may be partly or wholly inclined to the shaft 4 so as to retard the progress of the powder. Grease, such as stearic acid or lard, may be injected through a branch 25 into the inlet pipe or through a pipe 22 directly into the drum ; alternatively, the grease may be mixed with the powder. At the commencement, olive oil may be added followed, at a later stage, by a different material, such as stearine or stearine oil. To avoid oxidation of the powder by contact with air, the apparatus may be filled with a non- reacting gas, stop-cocks 23, 24 being provided to allow the receptacles 18, 19 to be changed without allowing air to enter. A fan 13 connected to the ends of the drum produces a current opposing the movement of the powder and serving to cool it and retard its progress : a propeller 13 fixed on the shaft 4 serves the same purpose. A sieve 16 separates powder from the air returning to the fan. The machine may have an intermittent action, the cocks 23, 24 being closed after a sufficient quantity of powder has entered the machine and reopened after a suitable lapse of time.

Patent GB-793362-A (GB)
Title: Improvements in or relating to carburettor controls
IPC: F02M19/12
Filed: 1954-11-08
Abstract: 793,362. Carburetters. BURGESS. P. Nov. 7. 1955 [Nov 8. 1954; March 25 1955] Nos 32303/54 and 8667/55. Class 7(3) A control mechanism for a throttle valve of an induction system for an internal combustion engine comprises an operator actuated member arranged for connection to the valve through a resiliently yielding connection and means responsive to changes in load on the engine adapted so to actuate the throttle valve that with increase of load the responsive means applies a closing force direct to the valve or to a part moving therewith overriding any force which can be applied by the operator actuated member through the yielding connection in the opposite sense but with decrease in load the responsive means permits the operator actuated member to open the valve at a rate dependent on the rate of decrease of load. As shown a suction controlled diaphragm 6 operates a stop 12 which co-operates with an arm 18 on the throttle valve spindle 30. The throttle valve is operated by an operator controlled member 27 which is freely mounted on the spindle 30 but connected to this spindle by a spiral spring 26. A dust cover 28 is fixed to the spindle 30 and a pin 31 co-operates with a slot 32 in the cover. The pin striking one end of the slot provides throttle valve closing means when the lever is moved in an anti-clockwise direction. Member 33 co-operates with a lug 34 to form a full throttle stop. The maximum position of opening of the throttle may be limited by limiting movement of the stop 12. The stop 12 can be moved away from the arm 18 by a control cable 24. In an alternative arrangement the means responsive to suction in the induction system may comprise the throttle valve itself which may be of the butterfly type and so mounted as to rock about an axis to one side of the centre of pressure of the valve so that decrease in suction on the engine side of the valve applies a force to it tending to close it whereas increase in suction tends to open it. In another alternate arrangement the means responsive to changes in load on the engine, may comprise a solenoid energized by the electric generator driven by the engine the output of which generator varies with the speed of the engine. In a further alternative arrangement the means responsive to the load on the engine may comprise means responsive to changes in pressure in the engine lubricating system.

Abstract: Thioindigoid dyes of the indirubin series are prepared by condensing 2 : 3-naphthoxythiophene, or a nuclear substitution product thereof, with polynuclear o-diketones such as an isatin or a homologue or halogen derivative thereof, or acenaphthenequinone. The products may subsequently be halogenated or further halogenated; they dye cotton in claret-red shades fast to chlorine and kier-boiling.  An example is given in which 2 : 3-naphthoxythiophene is condensed with dibromisatin and the product filtered, dissolved in sulphuric acid and precipitated by water.  In other examples the dyestuffs from 2 : 3-naphthoxylthiophene and the following components are brominated in nitrobenzene:-dibromisatin, isatin, and 5-brom-7-methylisatin.  The Specification as open to inspection under Sect. 91 (3) (a) refers to the use of homologues of 2 : 3-naphthoxythiophene in the above process, and describes also the bromination of the dyestuff from 2 : 3-naphthoxythiophene and acenaphthenequinone.  This subject-matter does not appear in the Specification as accepted.  Substitution products of 2 : 3-naphthoxythiophene.-1-Halogen derivatives may be obtained from 2 : 3-aminonaphthoic acid by the method described in Specification 231,567.  Other derivatives may be obtained by converting a 2-aminonaphthalene containing a substituent in the 1-position into the 2-mercaptan, condensing with monochloracetic acid, converting the thioglycollic acid into the acid chloride by means of thionyl chloride, and finally closing the oxythiophene ring by treatment with aluminium chloride in the manner described in Specification 14191/06.

In order to mask the line structure of the scanning raster of a cathode-ray tube, the scanning spot is elongated in a direction perpendicular to the lines by means of diametrically oppositely disposed two pairs of magnets 8, 9, Fig. 2, magnetized in a direction parallel with the beam axis laminations 14 constituting polepieces. The magnets are mounted in cylindrical cavities in a non-magnetic yoke 7 which may be clipped on the neck of the tube. A spring strip 12 is embedded by injection or casting into the yoke 7. More than two cavities may be provided, as shown, so that varying degrees of elongation may be obtained as desired by varying the number of magnets used. Alternatively, an electromagnet may be used comprising a winding (not shown) and a ferromagnetic casing 16, Fig. 3, formed of two halves, each having cut-away regions 17 to leave, effectively, polepieces 19 formed by the flanges on both halves of the casing, an airgap left between the flanges when the casing is assembled giving the required field. The airgap need not be central but located nearer the screen end of the tube, or the air-gap may be helical rather than circular. Springy tongues of insulating material are mounted on one of the halves of the casing to hold the assembly in position on the tube neck. The Specification describes a switching circuit for use with a cathode-ray tube to give either normal operation or to include the auxiliary magnetic system for giving an ellipsoidal scanning spot.
