Abstract: 1405179 Controlling oxygen steelmaking USS ENGS & CONSULTANTS Inc 18 July 1972 [27 July 1971] 33650/72 Heading C7D To obtain a desired final carbon content and temperature the hot metal and scrap components of the charge, and the amount of oxygen required, are determined in accordance with a mathematical model which has been developed by identifying the factors which influence the process and mathematically relating them to the bath carbon content. From the model there is obtained the relevant value of the constant (K) in an expression relating both carbon to oxygen blown in, e.g. of the form: whereby as the volume of oxygen blown in is continuously monitored the resultant carbon content is calculated and blowing stopped when the desired level is reached. Preferably the initially calculated value of the constant is revised when the precise composition of the hot metal, and the weights of all inputs, are known. Among the factors that may be taken into account in developing the model are oxygen, manganese and phosphorus contents of the bath, iron content of the slag, amount of fluorspar addition, steel recovery, and ratio of CO:CO 2  evolved during : refining. The model may indicate the need for addition of exothermic material such as calcium carbide, ferro-silicon, ferromanganese or silico manganese.

Title: Improvements in television systems
IPC: H04N7/12
Filed: 1938-11-21
Abstract: 521,477. Television. MAGUIRE, I. L. Nov. 21, 1938, No. 33836. Convention date, Dec. 3, 1937. [Classes 39 (i) and 40(iii)] Pictures are reproduced by signals or cathode rays EG1 which differ in phase and are derived from a single video signal generated by the progressive exposure of individual successive zones of the subject TF. The film TF is illuminated by a spot of light on the screen of a cathode-ray tube CR, and the spot has a length and breadth equal to a single scanning- line and is oscillated across the screen in the direction of the scanning-line. Alternatively light from the film passes through arcuate slots in a disc, Figs. 3-6 (not shown). Received signals are applied to two parallel networks- B1, B2. A direct signal is taken from the resistance VR, and a signal, which is delayed by the time for scanning an individual element of the picture, is taken from the capacitive or inductive branch of the network B2, Figs. 10 and 11 (not shown). Alternatively the branch B2 consists of a single capacitive or inductive branch, Figs. 12 and 13 (not shown). A signal which depends on the difference of the two derived signals is obtained by a differential amplifier RA2 and applied to a cathode-ray tube CR1. This signal is equivalent to a differentiation of the transmitted signal and is therefore equivalent to the brightness of the element of the picture which is being freshly exposed or occulted at the transmitter. According to a modification of the receiver, three cathode-rays EG1, Figs. 7, 8 form on a fluorescent screen three elongated spots of light Z, Z1, Z2, which are relatively out of phase by one element and are superposed as at ZO. The spots are elongated by a high-frequency oscillation applied to line-deflecting plates LS. The line Z1 is modulated positively and is twice as bright as the lines Z, Z2 which are modulated negatively.

Title: Controls for variable pumps or motors
IPC: F04B49/00
Filed: 1972-07-19
Abstract: 1401798 Fluid-pressure servomotor systems ADVANCED PRODUCTS PTY Ltd 19 July 1972 [28 July 1971] 33842/72 Heading G3P [Also in Division F2]  In a hydrostatic transmission control circuit wherein pump and motor displacement adjusting follow-up servomotors 10 are each controlled by a pilot valve 11 which is normally positioned by a manual control 23 acting through a further followup servomotor 18 on the pilot valve 11, over-ride means automatically adjust the pump and/or motor displacement when the pressure in the working circuit or the driving torque exceed predetermined values and the over-ride means is rendered inoperative during over-run of the motor. As shown the manual control 23 positions a pilot valve 24 of the follow-up servomotor 18. Pressure liquid supplied by a make-up pump 6 to a chamber 19A moves the servo-piston 18 against the bias of spring 21 to follow the movement of the pilot valve 24. If the make-up pump 6 fails, the spring 21 moves the servo-piston 18 left to reduce pump or increase motor displacement. Adjustably loaded normally closed over-ride valves 25, 26 are respectively loaded by working circuit high pressure 13 and a driving torque responsive pressure 17 which may be the hydrostatic pressure balancing the journal loading at the pump. When the pressure 13 or 17 exceeds a predetermined value the valve 25 or 26 is opened to vent the chamber 19A and thus reduce pump or increase motor displacement. The working circuit return line pressure 14 is supplied to an adjustably loaded normally open valve 27 which is closed by the increased pressure in the line 14 during motor over-run to block a vent duct 15 and thus render the over-ride valves 25, 26 of ineffective. Additional over-ride valve responsive to temperature or engine speed may be provided. In Fig. 3 (not shown) the overrun pressure (14) acts on a piston (28) connected directly to the servo-piston (18) to prevent leftward movement of the latter on opening of the valves (25, 26) and thus render the over-ride valves (25, 26) ineffective.

Filed: 1961-09-25
Abstract: 999,961. Apparatus for making tea and like beverages. J. STONE & CO. (DEPTFORD) Ltd. Sept. 25, 1962 [Sept. 25, 1961], No. 34312/61. Heading A4D. [Also in Division B8] Dry tea-leaves or like particles are dispensed to a brewing compartment in beverage-making apparatus, e.g. that described in Specification 870,763, by a reciprocatable slide comprising one or more measuring chambers 18 whereby two or more different amounts of tea-leaves or like material can be dispensed to the said compartment as required. The slide comprises plates 10, 11 and a measuring chamber 18 mounted for movement between fixed plates 13, 14 by a connecting rod 16 and a geared electric motor energized to automatically produce one or more reciprocatory movements of the slide. The chamber 18, which is shown in an intermediate rest position I is charged from hopper 1 at position II and discharged to a brewing compartment through an opening 21 in the fixed plate 14 at position III. To vary the amount of tea used, several reciprocations of the slide may be made to charge the brewing compartment, or a slide can be used with several transversely disposed chambers of differing capacity and a selector plate may be provided to prevent one or more of the chambers from being filled or discharged. The dispensing device is insulated from the rest of the apparatus and to prevent access of steam to the chamber 18 it is either moved to position I after discharge of its contents or an additional shutter closes opening 21. The lower side of the slide is heated to prevent condensed steam from making it too wet to operate and cooling 'air is circulated to cool the dry tea leaf. The hopper 1 is counterbalanced by a spring 26 which, if the weight of the hopper falls below a predetermined limit, operates a switch 28 which can switch off the apparatus or actuate a warning device. To prevent the slide from jamming, plate 13 may have slight free vertical movement on bolts 30 or may be spring loaded towards the slide; also to prevent dry leaf from penetrating between plates 10 and 13 a scraper ring and washer may be inserted around opening 20. The scraper ring may be associated with a telescopic measuring chamber. Specifications 999,962 and 999,966 also are referred to.
