Title: Improved servo controlled constant-pressure pump
IPC: F04B1/32

Abstract: 925,060. Fluid-pressure servomotor systems. BENDIX CORPORATION. Aug. 28, 1961 Aug. 30, 1960], No. 30980/61. Class 135. A constant pressure pump of the type having an inclined plate rotated by a drive shaft and acting to reciprocate a plurality of pistons in the cylinders cavities formed in the pump casing is provided with a pressureactuated piston acting on the plate to vary the inclination angle of the plate to a plane normal to the drive shaft axis thereby varying the amplitude of piston reciprocation and hence the pump delivery rate. The pressure acting on the piston is controlled by a valve member automatically displaceable to control the communication between a piston on the one hand and the pump output and a drain passage on the other hand, the valve member being positioned in accordance with the pump output pressure in such a way that a decrease in pump output pressure displaces a valve member in a direction to cause said piston to increase said plate inclination angle and hence increase the pump delivery rate and vice versa. The swash plate is adjusted by movements of a piston 52, the swash plate being loaded into contact with this piston by a spring. The control valve 66 is loaded by a spring 68 against the pump output pressure acting on the end of 70 and the land 72 controls the flow of output pressure to a passage 80 and the flow from this pressure through a groove 76, passage 74 to the drain passage 82. A permanent restricted leakage from passage 80 is provided by a restricted bleed passage 94 communicating with passage 74. In one modification this bleed passage is replaced by a chamfer or groove on the left-hand side of the land 72 and in a further modification by two open recesses on either side of a groove 78 communicating with passage 80. In a still further modification, the leakage is provided by a restricted passage through the piston 52.

Title: Improvements in the manufacture or treatment of yarns, threads, fabrics and other textile materials, and films, foils and the like
IPC: D01F2/28
Filed: 1934-11-02
Abstract: The tendency of yarns, films, fabrics, and the like to become charged with static electricity is reduced by depositing in or on such materials a salt of an organic base and a hydroxycarboxylic acid. Examples of such salts are salts of saccharic, mucic, gallic, tannic, salicylic, tartaric, lactic, or citric acid with alkylolamines, e.g. mono-, di-, and tri-ethanolamine, dipropanolamine, or hydroxy ethylaniline.  The de-electrifying substances may be used with lubricating agents such as blown olive oil, sulphonated castor oil, olive oil, mineral oils, rape seed oil, animal oils, glycol, glycerol, and the oleates and stearates of glycol and glycerol.  The process is of particular importance in the treatment of yarns, films, and fabrics formed of organic derivatives of cellulose, but may also be employed in the treatment of materials of regenerated cellulose, wool, cotton, silk, flax, or other fibres.  The de-electrifying substance may be applied from solution or dispersion, for example, in aliphatic polyhydric alcohols, or water and oil or modified oils. When the medium is hygroscopic, e.g. in the case of ethylene glycol and glycerol, water is preferably added.  The yarns or films may be treated with the agents by means of a wick, pad, drip-tube, or rollers, for example, the wick device of Specification 366,585. Fabrics are preferably treated by means of rollers, or by passing them through a bath of the agent.  In an example, filaments of an organic derivative of cellulose are passed in contact with a wick dipping into a solution containing blown olive oil and triethanolamine lactate, so that the filaments take up 2,5 per cent of the liquid.  The Specification as open to inspection under Sect. 91 relates to a process in which yarns, films, and fabrics are treated with an organic acid salt in which the basic and/or acidic radical contains a free hydroxy group.  Suitable acids which do not contain hydroxy groups are anisic, benzoic, succinic, maleic, and fumaric acids.  This subject-matter does not appear in the Specification as accepted.
