Abstract: 541,122. Testing hardness of materials. CRADICK, M. J., DUNTON, A. R., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. June 11, 1940, No. 10174. [Class 106 (ii)] Comprises a scratch test in which the specimen is reciprocated in the same track under a loaded stylus and the extent of movement of the stylus after a time or the time to make a predetermined movement being taken as a measure of the hardness. The specimen 3 is clamped between upper and lower plates constituting a table 3 supported by pillars 10 from a plate 9 oscillated about a vertical axis by pin and slot 7, 8 from a gravity returned slide 6 reciprocated by a cam 5 driven by a motor 4. A stylus 11 carried by an arm 12 having pan 13 for loading weights and and pivoted about an horizontal axis 14 and pillar 15 extends downward to engage the specimen 3 through an arcuate slot 19 in the upper clamping plate. The pillar has secured to it a radial arm 16 along which a clamp 17 can be adjusted the clamp being attached to a spring 18 anchored to a fixed point. As the specimen is oscillated under the stylus the friction increases and the pillar 15 is increasingly deflected about its axis against the influence of the spring 18. When the deflection, reaches a predetermined amount, the arm 12 engages a stop 20 and trips a switch to stop the motor. The time taken to reach this deflection is a measure of hardness.

Title: Process and apparatus for reducing metal oxides without melting
IPC: C21B13/08
Filed: 1960-03-24
Abstract: 894,348. Production of sponge metals. FREEMAN CORPORATION. March 24, 1960 [April 8, 1959], No. 10531/60. Classes 72 and 82(1). [Also in Group XII] The process for the production without melting of sponge metal, especially iron, cobalt, nickel and copper, by reduction of metal oxide pellets with finely divided reducing agents in a rotating kiln or reducing furnace (A), cooling the reduced product in a rotating tube (R) and separating the sponge metal from the residue, is characterized by the step which comprises transferring the hot reduced product from the interior of the bed of reduced product with the contained reducing gases directly from within the kiln to the cooling tube by a scoop (K) on the kiln end of the tube to avoid admission of oxidising gases, e.g. from the chimney (N), to the product. Preferably the hot mass is continuously withdrawn from the kiln and continuously discharged from the cooling tube at the discharge orifice (S). For sponge iron, the kiln may be charged through (E) with 100 parts by weight of porous iron ore pellets, at least 40 parts of coke passing # inch mesh and at least 10 parts of limestone or dolomite; a reducing temperature of 900-1050‹C. is provided by burning oil or gas fuel supplied through inlet (F).

Title: Odd mark detector for radio printing telegraph systems
Inventor: BERWIN TED W
IPC: H04L1/00
Filed: 1955-04-13
Abstract: 774,943. Code telegraphy. COLLINS RADIO CO. April 13, 1955, No. 10592/55. Class 40 (3). A telegraph transmitter arrangement employing the five-unit code of marks and spaces includes a detector circuit for determining whether the number of marks is odd or even and a check signal element is sent at the beginning of the corresponding code combination. Relays 17 ... 21 controlled by the perforations of the tape passing through the transmitter 10 control armatures A1 ... A5, connected in the detector circuit, and additional armatures D1 ... D5 connected in parallel to the winding of a relay 59 and associated with upper contacts E1 ... E5 connected to segments 2 ... 6 of a distributer 44 operated by an oscillator 43. Relays 52, 53 are controlled by the positions of the pairs of armatures A2, A3 and A4, A5 and a further relay 57 is under the joint control of the positions of the armatures A6, A7 of the relays 52, 53. If the armatures A2, A3 are in opposite positions relay 52 is operated and similarly, relay 53 is energized solely when A4, A5 are in opposite positions. The relay 57 is operated when the armatures A6, A7 are oppositely positioned, indicating an odd number of marks recorded on relays 18 ... 21. Relay 57 remaining unoperated with the armature A8 against contact B8 indicates an even number of marks in the elements two to five of the code combination. With relay 57 operated for an odd number of marks and a space on relay 17 moving armature A1 against contact B1, a pulse from the oscillator 43 through segment 1, contacts B1, C8 operates a relay 59 moving the armature 62 to contact 63 so that a frequency F1 representing a mark is passed from the oscillator 66 to the transmitter 76. If the element on relay 17 had been a mark, a circuit is not completed for the relay 59 and a frequency F2 is passed from an oscillator 67 denoting a space, since the total number of marks is even. If relay 57 is unoperated, i.e. A8 engaging B8, denoting an even number of marks on relays 18 ... 21, a mark on relay 17 energizes relay 59 to send frequency F1, whilst a space leaves relay unoperated and the spacing frequency F2 is transmitted. The sequential pulses through segments 46 to 50 of the distributer 44 selectively operate relay 59 to effect the transmission of the marking frequency F1 in accordance with the operated positions of the armatures D1 ... D5 of the relays 17 ... 21. The impulse applied to the segment 51 operates relay 68 so that the synchronizing frequency F3 from the oscillator 74 is applied to the transmitter 76. The pulse applied to the segment 51 is also fed to the transmitter 10 to step the tape for sensing the subsequent group of perforations.

Title: Process for the continuous dyeing of cellulosic fibre webs with sulphur dyes and derivatives thereof
IPC: D06P1/30
Filed: 1976-03-17
Abstract: Web-form cellulose fibre textile goods are padded on a padder with a small liquor trough using an aqueous liquor of these dyestuffs in leuco or thiolsulphato form heated to a temperature of 90 to 95 DEG C. In this process, a padding liquor is used to which a sodium polysulphide of the formula Na2Sx, in which x denotes a number from 2 to 5, has been added before use. The padded cellulose fibre textile goods are passed, after an air passage lasting at least 10 seconds, through a full-width washer, in which the padded dyestuff is converted into its disulphide form again by reoxidation. The sodium polysulphide added to the padding liquor in the form of an aqueous solution prevents the spontaneous oxidation of leuco or thiosulphato dyestuff and thus a bronzing of the dyeing during the air passage of the cellulose fibre textile goods.

Filed: 1943-07-02
Abstract: 569,255. Steam turbine plants. SULZER FRERES SOC. ANON. July 2, 1943, No. 10750. Convention date, July 16, 1942. [Classes 110 (iii) and 122 (iii)] Two or more feed-water tanks 17, 18, each has one or more independent supply pumps 19-22 which delivers into a supply pipe 26 or 29 past a non-return valve 33-36. Preferably a changeover device is provided by means of which the delivery pipe of the supply pumps of one tank can be shut off from the feed pipe and can be connected to the tank so that the tank contents are circulated. High - pressure boilers 1, supply steam through mains 2 to high-pressure turbines 3. Exhaust stearr passes through pipes 5 to low-pressure turbines 8 by way of superheaters 6, heated by steam from the boilers 1, and pressure. equalising chambers connected by pipes 7. Condensate from condensers 10 passes through pumps 11 into pipes 12, 13. Extracted steam is led through pipes 14 into pre-heaters 15 and mixers with the condensate. The pumps 19-22 are slow-speed, double-inlet centrifugal pumps. Coolers 37, to which colder condensate may be added, are provided, to prevent temperature and pressure fluctuation in the tanks. The pumps 19-22 supply pipes 26, 29, leading to high-pressure pumps 23, which deliver feed to the boilers 1, through an equalising system 31. All main piping is duplicated to facilitate disconnecting components for servicing, without the necessity for closing down the plant. Piping 38 leads liquid and wet steam from the boilers when they are started up, to the tanks 17, 18. The latter can be used as steam accummulators with pipe 39 connected with the pipes 5, the pressures in the tanks varying in accordance with the steam demand. The pumps 11 may deliver into one tank only, e.g., 17 by opening valves 40, 42, and closing valves 41, 43. To obviate cooling in the tank 18, a valve 45 is opened to allow pumps 21, 22, to circulate water from the bottom of the tank 18 through pipe 13 into the top of the tank. A change-over device whereby the delivery pipe of one of the supply pumps can be connected to the other tank is obtained by closing valves 40, 41, 42, 43, 44, 45, in the by-pass pipes, and 49. Valve 48 is left open so that water can pass from the tank 17, through pipe 50, and into the tank 18. Preferably, valves 48, 49, are automatically controlled by the water levels in the tanks. When the tanks are used as steam accummulators, a delivery pressure regulating device is provided for the H.P. turbines 3, and the L.P. turbines 8 are regulated by governors. The turbines 3 may also have governors. The boilers are preferably of the H.P. tubular type, and may be used in conjunction with L.P. boilers. The tanks 17, 18, may be designed as fire-tube boilers.
