Filed: 1936-12-12
Abstract: 486,893. Hydraulic c brakes. HYDRAULIC BRAKE CO. Dec. 12, 1936, No. 34173. Convention date, Dec. 14, 1935. [Class 103 (i)] [Also in Group XXIX] Connecting means between the reservoir and a master cylinder suitable for hydraulic brakes comprises an annular space concentric with the discharge passage of the cylinder and communicating with the reservoir and a valve adapted to close communication of the annular space with the cylinder when the cylinder is operated to apply pressure to the system. In the Figure, the cylinder head 26 has an extension 30 provided with passages 36 normally affording communication between the reservoir 10 and the cylinder through passage 24 and annular space 34. A valve 72 for closing the passages 36 is normally unseated by the head 78<1> of a rod 68 secured to the piston 60 which is retracted by a spring 80 bearing on a washer 82. When the piston is moved forwardly to force liquid through the outlet 28, the valve is seated by a spring 78 disposed between the valve and piston. If, during the retraction stroke of the piston, a vacuum tends to form in the system, the valve unseats against the action of spring 78 to admit liquid from the reservoir to the cylinder. A flexible washer 38 forms the valve seat. In a modification, the valve is seated by a spring disposed between it and the washer 82 and the retracting spring 80 bears on a metal cup to which the valve rod is secured and which bears on the cup 70.

Title: Improvements in or relating to the production of artificial textile yarns or threads
IPC: D01F2/30
Filed: 1928-11-21
Abstract: 325,823. British Celanese, Ltd., and Taylor, W. I. Nov. 21, 1928. Yarns and thrcads.-A substance having a solvent, restricted solvent, or softening action is applied at intervals along the length of a number of artificial filaments causing them to adhere in such a manner as to form a yarn or thread consisting of alternating lengths of independent filaments separated by lengths of filaments united together as a single filament. The filaments may be employed in the form of one or more twisted or untwisted threads, and two or more groups of filaments may be given the same or different arrangements of united and independent filaments which are then associated as a thread with or without twisting. The solvent or softener is preferably applied in quantities just sufficient to secure adhesion of the filaments. Other yarns, filaments, or threads, or metallic wires or tapes may be associated with the filaments to be treated, and incorporated in the yarns produced. After receiving the solvent or softener, the united filaments may be subjected to pressure with or without crinkling or embossing so as to give them a flattened cross-section. The filaments may be treated at the time of their production or during a bobbin-to-bobbin or other winding operation. In the case of cellulose acetate, suitable solvents or softening agents are acetone, triacetin, ethyl lactate, diacetone alcohol, and mixtures of diacetone alcohol with water or alcohol. Filaments of esters or ethers of cellulose to which the treatment is particularly applicable are cellulose acetate, formate, propionate, butyrate, nitrate, methyl-, ethyl-, and benzyl-cellulose, and the condensation products of cellulose with glycols or other polyhydric alcohols. Dyes or metallic powders may be added to the solvent and applied therewith to the filaments. A bundle of filaments 7, produced in a spinning cell 8, is led round a feed roller 9 and proceeds to a wick 10 which is' moistened with solvent from a container 12. Arranged between the roller 9 and the wick 10 is a device 13 having radial arms which rotate and lift the filaments 7 from the wick 10. The length and speed of rotation of the radial arms determines the arrangement of free and united portions of the filaments 7. By having a plurality of devices 13, rotating at different speeds, the arrangement of free and united portions of the filaments 7 may be varied in any desired manner. A wick 17 supplied with olive oil intercepts the filaments on their way to a winding device 18 so as to remove any residual stickiness. Instead of the wick 10, a roller rotating partly in a trough containing the solvent mav be used, and instead of the wick 10, and the device 13, a number of wicks 24, supplied with solvent and radially mounted on a shaft 22 may be employed. Other threads may be withdrawn from a bobbin 28 and treated with the filaments 7. Specifications 306,050, 326,462 and 328,312 are referred to.

Title: Improvements in or relating to steam boilers
Inventor: MITCHINSON STANLEY THOMAS
IPC: G05D16/20
Filed: 1964-08-25
Abstract: 1, 084, 519. Automatic control of boilers. EDWIN DANKS & CO. (OLDBURY) Ltd. Aug. 25, 1965 [Aug. 25, 1964], No. 34742/64. Heading G3R. [Also in Division F4] In a boiler control system in which rate of firing is automatically varied in dependence on steam demand, water in the boiler is automatically maintained at one level for boiler pressures above a predetermined value and at a lower level for boiler pressures below that value. A system of switches and electromagnetic relays for controlling boiler firing, feedwater supply, and a flue damper is described. At normal boiler pressures the rate of boiler firing is controlled in accordance with load demand in an unspecified manner. Under these conditions a switch responsive to level of water in the boiler controls a solenoid-operated feedwater supply valve to maintain a predetermined high level of water in the boiler. If, owing to heavy load when the rate of firing is a maximum, boiler pressure falls, a pressure responsive switch substitutes another switch responsive to level of water in the boiler so that a lower level of water is maintained until pressure is restored. If a predetermined high boiler pressure is exceeded, boiler firing is cut-off. If water level in the boiler exceeds a predetermined level, an alarm is operated.
