Title: Articles having hydrophilic surfaces and methods of preparing them
IPC: B41N3/03
Filed: 1958-06-19
Abstract: The surface of an article is rendered hydrophilic by applying thereto a silane of the formula CH2=CH.SiR3, wherein R is an alkoxy or aryloxy radical or a halogen atom, and acrylic or methacrylic acid or a water-soluble salt thereof, acrylamide or methacrylamide, and copolymerizing these reactants (see Group IV(a)).  The silane and acrylic compound may be applied to the surface either simultaneously or successively and then copolymerized.  In Examples (1) a zinc plate, (2) an aluminium p  roller, (4) a copper plate, and (5) an aluminium sheet, are coated as above.  Other metals specified are tin, lead, chromium, steel, magnesium and anodized aluminium.ALSO:A copolymer is formed in situ, as a hydrophilic coating on the surface of a roller or other article (see Groups III and VIII), by copolymerizing acrylic acid, methacrylic acid, a water-soluble salt of these acids, acrylamide or methacrylamide, and a silane of the formula CH2 = CHSiR3, wherein R is an alkoxy or aryloxy radical or a halogen atom.  The silane and acrylic compound may be simultaneously applied to the surface as a mixture in a solvent and then co-polymerized.  Preferably the silane (in solution in e.g. toluene, benzene, xylene, pentane, hexane, heptane, octane, carbon tetrachloride or chloroform with or without a condensation catalyst, e.g. ethanolamine) is first applied to the surface and heat is applied to remove solvent and promote formation of a polysiloxane through hydrolysis by surface and/or atmospheric moisture; the acrylic compound is then applied as a solution in e.g. benzene, toluene, xylene, pyridine, petroleum ether, methanol, ethanol, butanol, monoalkylethers of ethylene glycol, chloroform or carbon tetrachloride, together with a polymerization catalyst, e.g. benzoyl, acetyl, urea- or hydrogenperoxide, cumene hydroperoxide or potassium persulphate, and the assembly is then heated at 120 DEG -300 DEG  C. for from 10 minutes to 12 hours.

IPC: B66B1/08
Filed: 1923-08-01
Abstract: 221,063. Hamilton, W. L. Aug. 1, 1923. Systems controlling travel for a fixed distance and for controlling reciprocating motion.-Relates to the control of electric motors which are required to make forward and return movements as in cable haulage, and consists in improvements in automatic-control gear of the kind described in Specification 9152/14, wherein a motor is started, stopped, and reversed by switches actuated by the fall cf weights which are periodically raised by motor-actuated mechanism. According to the invention, chain and sprocket mechanism is used for raising the weights and for removing resistance from the motor circuit. In the apparatus shown, the weights G are raised on travelling platforms E<2> which receive motion from endless chains E, E<1> driven by sprocket-wheels 5. The extent of lift and consequently the distance run by the motor can be varied by varying the position of engagement between the chain and the platform. Other similarly-driven chains B, B' actuate a motor resistance switch C which removes resistance from the motor circuit at the beginning of a forward movement and reinserts it at the completion of a return movement.

Title: Improvements in or relating to time delay switches
IPC: B60R16/00
Filed: 1947-07-24
Abstract: 625,001. Time switches. LUCAS, Ltd., J., and ALLEN, A. M. July 24, 1947, No. 19862. [Class 38(v)] A switch for controlling a direction indicator on a vehicle is closed by rotating a spindle which simultaneously winds a clockwork mechanism. When the spindle is released the clockwork unwinds but the switch remains closed for an interval of time due to a lost-motion device between the clockwork and switch actuator. Fig. 5, is a plan of a part of the switch in which 2 and 3 are the moving and fixed contacts and 7 the winding spindle of the clockwork The upper end of the spindle carries an insulating cylindrical member 8 formed with a sector-shaped slot 9 in which a lever 10 is pivoted at 11. If two indicators are to be operated a second slot 9 and pivoted lever 10 are provided to actuate a second moving contact 4 into and out of engagement with a second fixed contact (not shown). Each lever 10 can oscillate about its pivot 11 through an arc bounded by the walls of the slot 9. In the position shown in Fig. 5 the spindle 7 has been rotated counterclockwise to wind the clockwork and cause the lever 10 to press the contact arm 2 into engagement with the contact 3, the lever riding up and engaging behind a cam-shaped projection 12 formed on the arm 2. As the clockwork unwinds, the member 8 rotates clockwise while the lever 10 remains stationary against the projection 12 until it is engaged by the wall of the slot 9. The lever then rotates with the member 8 and rides over the projection 12 causing the arms 2, 3 to separate. The switch arm 4 is similarly closed against its fixed contact and opened automatically after an interval of time by rotating the spindle 7 in a clockwise direction. Fig. 7 shows a modification in which a second lever 13 in the form of a ramp is pivoted on the pin 11 and engages the moving contact before the lever 10 so that a more gradual movement of the contact is produced. The clockwork is wound up by a rotation of the spindle 7 in either direction by the arrangement shown in Fig. 2. The spindle carries a symmetrically-shaped cam 14 which co-operates with a pin 15 projecting from a plate 16 pivoted at 16a. The plate carries a rack engaging a pinion 18 of the clockwork train the speed of which as it runs down is controlled by an escapement. The main spring 17 is connected to the plate 16 and to the casing of the apparatus. Rotation of the cam 14 in either direction moves the pin 15 and plate 16 to strain the spring 17.
