Patent GB-969039-A (GB)
Title: Water activator
IPC: D06F35/00
Filed: 1961-09-12
Abstract: Apparatus for activating water flowing through a line comprises a chamber having an ultra-violet lamp therein whereby the air in the chamber is ionized, and a unidirectional valve coupling the chamber to the line, so that as water flows through it the suction created draws in ionized air to mingle with the water.  In the embodiment shown, the invention is applied to the water inlet line 12, 11 of a washing-machine 10.  This line passes through a chamber 13 in which is mounted an ultra-violet lamp 18, the lamp ionizing the atmosphere within the chamber to produce negative ions and also free oxygen atoms which later will combine with the water to form hydrogen peroxide.  A quartz porthole 23 enables the lamp to irradiate the water in the line directly.  The charged atmosphere from the chamber is drawn into the water line through a valve member 24 in a lateral stub 15a .  The valve is formed by a cone-shaped element of flexible plastic material having at its apex two flattened lips which can be distended and opened by gas pressure.  As the water flows down the pipe, the vacuum caused by the Venturi action acts to suck charged gas in from <PICT:0969039/C1/1> <PICT:0969039/C1/2> chamber 13.  Fig. 5 shows an alternative form of valve, comprising a cylinder 26 within which a piston moves.  The piston consists of upper and lower sections 30, 32, spaced apart by bolts 34, 35, both sections having Venturi passages bored therein.  A side port 29 connects to the ionizing chamber 13.  When no water is flowing, the piston is urged by a spring 37 to the top end of the cylinder housing 26, access from the side port 29 then being shut off (Fig. 4, not shown). When water is flowing down the line, the pressure forces the piston down against the spring, as shown in Fig. 5, opening the side port entry and drawing in ionized air.  It is stated that this ionic activation of the water enables washing to be carried out at a lower temperature than usual, and without the use of soap or detergents.  Another application is to inhibit the growth of fungi in swimming pools.

Filed: 1920-11-22
Abstract: 171,621. Lorkin, W. L., Daglish, E. E., and Swift, H. B. Nov. 22, 1920. Reel and web apparatus.-Operating means for vehicle route indicators, of the type in which a band is wound from one to the other of two rollers, comprises a spindle E carrying two helically-cut toothed pinions J engaging helically-cut toothed pinions K on the rollers A. The spindle E may be turned by a handle F, which may be secured from longitudinal motion and the spindle E made slidable therein. Reversal of the direction of rotation of the spindle effects disengagement of one pair of pinions J, K, and engagement of the other pair, thus changing the operating roller and reversing the direction of motion of the band B. The spindle E works in two or more bearings H which act as thrust blocks to limit the longitudinal travel of the spindle. Each roller A is made detachable by having wings D' or the like at one end to engage, e.g. a central hole with cross-slots in the pinion K, and by mounting the other end C' in a spring or a spring-pressed plate N. Friction davices R may also be included.

Abstract: 1,190,094. Printing apparatus; transfer cylinder. MILLER PRINTING MACHINERY CO. 19 July, 1967 [16 Jan., 1967], No. 33091/67. Heading B6C. A transfer cylinder for a printing press comprises a pair of sheet-engaging means so arranged that a sheet may be transferred from one to the other wherein one of the sheet-engaging means is mounted on a tumbler shaft and is biased towards an outer or untumbled position and drive means connected via an actuator shaft to the tumbler shaft are operable to cause the sheet-engaging means to tumble or swing inwards, the torque to the tumbler shaft being imparted at a point intermediate the ends of the shaft. The transfer cylinder is especially applicable as the third transfer cylinder of a multi-colour and perfecting press as disclosed in U.K. Specification No. 735,477 in which the pair of sheet-engaging means are both gripper assemblies, one assembly being optionally used to engage the trailing edge of a sheet and reverse it for perfecting by transferring it to the second gripper assembly; when the press is being used for multi-colour printing, the first assembly is inactive (Fig. 1, not shown). Figure 4 illustrates the drive mechanisms for the tumbling of gripper assemblies 22, 24 carried on tumbler shafts 110; each drive shaft 64 is rotated by a cam roller (60), (Fig. 2, not shown), riding on a cam surface (62) at the end of the cylinder, and is connected to an actuator shaft 86, Fig. 6, by linkage 90. Shaft 86 carries at a point intermediate the ends of the cylinder, a gear segment 178 meshing with gear teeth 176 on a pinion 174 which rotates with shaft 110. Thus, rotation of drive shaft 64 in one direction tumbles the respective gripper assembly against the resilient bias of springs (158), (Fig. 5, not shown). The cam mechanisms (60, 62), are rendered inoperative when the press is not perfecting so that both assemblies remain in their untumbled position. The gripper assemblies are conventional cam-operated mechanisms.
