Title: Improvements in and relating to hydraulic press operators
IPC: D06F71/06
Filed: 1950-09-13
Abstract: 689,653. Hydraulic presses. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 13, 1950 [Sept. 28, 1949], No. 22529/50. Class 69 (ii). The speed of a hydraulic piston 6 during its working and return stroke in a cylinder 7 is varied by a fluid control valve at the cylinder head comprising two telescoping sleeves 60, 63 the first of which is secured to the piston head 32 and the second has a lost motion connection with the first to delay its movement until after a predetermined piston movement ; the  sleeves 60, 63 project into a well 58 at the beginning and end of the working and return strokes respectively, and fluid passes through ports 67 in the sleeve 63 to the annular space between the well 58 and the sleeves 60, 63 and thence to the cylinder space beneath the piston head 32. The working fluid is pressurised by an impeller 41 located in the piston head and driven by an electric motor 35, and the return stroke is effected by gravity assisted by springs. At the start of the working stroke the throttling annulus and hence the piston speed remains constant at a low value until the sleeve 60 emerges from the well whereupon the speed assumes a slightly higher constant value. When the sleeve 63 is picked up by the sleeve 60, the ports 67 deliver directly into the cylinder space and the piston rapidly assumes its maximum speed. The finish of the return stroke is cushioned at a uniform rate when the sleeve 63 enters the well 58. The apparatus is applicable to domestic ironing machinery of conventional construction.

Low-pressure metallic-vapour apparatus.- The vapour of an alkali metal such as caesium or rubidium is introduced into a discharge tube for use as a lamp; rectifier, or lightning-arrester, the starting voltage being lowered thereby. The gas filling consists of neon at pressures varying from 2 mm. to 3 cm. of mercury, or of krypton, or of mixtures of neon, helium, and argon. It is stated that such a lamp containing neon at a pressure of 2.7 cm. starts at 76 volts continuous and 60 volts alternating. The lamp shown in Fig. 1 comprises two electrodes 2, 3 of iron, nickel, molybdenum, aluminium, or other material having a neglible vapour pressure at the operating temperature, separated by a sheet 4 of glass. Conductors 8, 9 are connected by screws with the electrodes, the conductor 8 being insulated from the electrode 2 by mica 12. Anchors 13 connected with and insulated from the electrodes are held loosely in projections 15 on the tube. A distillation bulb 18, Fig. 5, having two or more purification bulbs 19, 20, is attached to the tube, and the tube and bulb are baked out at 450‹ C., and exhausted, care being taken to remove, water vapour, for instance, by means of a liquid air trap. When the apparatus has cooled to air temperature a mixture of calcium turnings with an excess of caesium chloride is admitted into the bulb 18, which is then sealed and heated with the tube while on the pump to 250‹ to remove water vapour. Heat is applied to the bulb 18 to distil caesium successively into the bulbs 19, 20 and into the tube, which is then sealed off. The connection 23 to the pump is closed and gas admitted through a tube 22. In another form of lamp the electrodes consist of closely adjacent helices. In the rectifier shown in Fig. 2, the cathode 28, which has a surface at least 300 times as great as that of the anode 29, is mounted on an insulating stem 32, the anode consisting of tungsten, iron, nickel or carbon.
