Title: Gas-valve for liquid-heaters
IPC: F24H9/20
Filed: 1931-03-20
Abstract: 366,777. Fluid-operated valves. WENDER, E., 62A, Leipzigerstrasse, Frankfort-on-Main, Germany. March 20, 1931, No. 8693. [Class 135.] A liquid-heater gas valve actuated by a diaphragm acted upon by the flowing water has several separately loaded steps placed one after the other. As shown a valve rod 8 controlled by pressure fluid on a diaphragm 3 carries a valve disc 17 loaded by a spring 20. The disc controls openings 16 in a valve member 15 slidable on the spindle 8 and covering an aperture 14 in the casing 9. The member 15 is loaded by a spring 19 and the springs 19, 20, are adjusted by screws 22, 21. For small pressures on the diaphragm 3 corresponding to a small amount of liquid drawn from the heater the smaller valve step 17 only is opened. As the amount of liquid drawn off increases the continued movement of the spindle 8 causes an adjustable cam 18 thereon to move the valve member 15 and uncover the aperture 14, the apertures 16 still remaining open. The openings 14, 16, are closed in the reverse order.

Abstract: 1,148,347. Sheave blocks. BYRON JACKSON Inc. 23 Feb., 1967 [5 Aug., 1966], No. 8745/67. Heading B8B. A travelling block assembly comprises a pair of sheave blocks 5, 6, an adaptor 4 U- shaped in the horizontal plane and each arm thereof engaging a sheave block, and devises 9, 10 coupling the adaptor to an elevator 2 for raising or lowering a well casing or the like 3. Each sheave block comprises one or more sheaves supported in roller bearings between guard plates. The latter are supported apart by spacers 30, 31 bolted to the plates. A lug on each arm of the adaptor 4 is received between the guard plates of the associated sheave block and is connected thereto by a bolt 38. A land 26 at the base of the inner guard plate mates with a land on the adaptor 4 to prevent relative pivoting between the block and adaptor about the bolt 38. Rubber deflectors 11, 12 on the insides of the sheave blocks act as bumpers and guides from the casing 3. Closure panels 39, pivoted to the guard plates shield the sheaves in use. In the embodiment of Figs. 7 to 10 (not shown) a third sheave block is mounted in similar fashion to the first said two, on the back of the U-shaped adaptor.

Title: Improvements in telemetering systems
IPC: G08C19/16
Filed: 1946-03-26
Abstract: 610,349. Telemetering systems. GENERAL ELECTRIC CO., Ltd., SMART, N. C., and CHUBB, A. A. March 26, 1946, No. 9248. [Class 40 (i)] In a telemetering system in which a device such as a rotating meter produces pulses at a rate proportional to the value of the quantity which is to be remotely indicated, a condenser is fully charged or discharged by a pulse and partly discharged or charged in the interval between two pulses, the residual charge, which is proportional to the time between the pulses and therefore to the pulse frequency being compared with a standard voltage on a D.C. potentiometer and the out-of-balance current being used to control an electromagnetic stepping switch to alter the potentiometer tapping until balance is obtained. As shown, the first operation of line relay A, which responds to impulses from the distant meter, energizes B which charges condenser Q1 rapidly and at the end of the impulse remains locked up in series with C which then connects Q to a high resistance R1 to discharge it slowly and locks up in series with another winding B, the initial circuits of both relays being broken. The next impulse shunts out B, but C remains locked until the end of the impulse and then connects Q via resistances R3, R4, to a point on a potential divider R7 selected by a switch WA. If any difference in potential exists, the resulting modification of the potential of the grids of gas-filled tubes V1, V2 connected to R3, R4 causes one or other of them to fire and so complete a self-interrupted stepping circuit to drive the switch in such a direction as to nullify the potential difference. Alternatively, vacuum tubes with relays for controlling the stepping circuits in their anode circuits may be used. A further alternative dispenses with tubes and provides a differential relay in place of resistance R3, R4. The switch shaft also carries an indicator or a wiper controlling voltage or current in an indicating circuit. The indicating circuits of several telemetering lines can be associated to give a grand total.

Convention date, April 20, 1934. [Class 55 (ii)] Carbonized briquettes are made by mixing a small amount of finely powdered dry amylaceous binder with a larger amount of very fine coal powder having coking properties, mixing the product with anthracite or similar close burning fines, slightly heating and briquetting the mixture and finally baking the briquettes at about 560-650‹ C. If the fines have a humidity of 10 per cent or less drying is unnecessary. The mixture may be worked up at about 70-80‹ C. in apparatus heated by superheated steam and briquetted in a continuous rotary press, afterwards being distilled at 550-650‹ C. in an oven of the type employing a rapidly circulating gas in contact with the briquettes. In an example 1À8 parts of rice starch are mixed with 30 parts of powdered coking coal having 27 per cent of volatiles and 19 per cent of ash, this mixture being added to 68À2 parts of fines and the whole heated by superheated steam to 80-100‹ C. and pressed. The briquettes are baked for 50-60 minutes up to 600‹ C. Other amylaceous binders include the starch of rye, corn, maize, potato and chestnut. High volatile coals, bituminous, flaming, cannel, &c., which fuse on heating but do not yield a good coke may be used as the coking powder.
