Title: Improvements in or relating to ball point pens
IPC: B43K7/02
Filed: 1950-01-17
Abstract: 730,951. Reservoir pens. GILLEN, R. Jan. 10, 1951 [Jan. 17, 1950; May 3, 1950], Nos. 1192/50 and 10884/50. Class 146(3). In a ball-point pen a capillary conduit is open at one end to atmosphere and at the other end opens into the ink reservoir, and a plunger which closes the end of the reservoir remote from the writing point can be manually adjusted along the reservoir to cause ink to flow from the reservoir into the capillary conduit. As shown in Fig. 1, the pen barrel 1 forms the reservoir 1A the open end of which is sealed by a piston 11 adjustable along the reservoir by a screw 12. A capillary passage 5, integral with the barrel 1, is open to atmosphere at the upper end through a hole 8 in a screw cap 7, and its lower end 5A is slightly above the inlet to the ink feed passage 2 which leads to the writing ball 3. When the reservoir 1A and passage 5 are filled with ink the ink in the passage is used first, and this is then replaced by moving the plunger 11 downwardly. The opening 5A may be so small that the capillary pull of the meniscus of the ink when the passage 5 is almost exhausted will be greater than that exerted in writing and so prevent ink reaching the ball 3 and warn the writer that the plunger 11 should be depressed. In a modification (Fig. 4, not shown), the capillary conduit comprises a separate central tube having screw-threaded engagement with the plunger in the reservoir, the upper end of the tube extending beyond the plunger and serving to move the latter on being rotated. In Fig. 2 a central capillary tube 13 is secured at the lower end to a plunger 14 having screw-thread engagement with the barrel 1. When the ink in the tube 13 is used up, the tube is rotated to move down the plunger and so refill the tube. In modifications of this construction, the plunger may have purely frictional engagement with the inside of the reservoir and comprise two annular discs spaced apart by a rubber disc, and the lower end of the capillary tube may have its bore reduced, say by the insertion of a perforated plug therein, to cause cessation of ink flow to the ball when the tube is almost exhausted.

Title: Improvements in or relating to the loading and regeneration of ion exchangers used in ion exchange processes
IPC: B01J47/02
Filed: 1953-01-15
Abstract: <PICT:0725660/III/1> <PICT:0725660/III/2> A method of loading and regenerating an ion exchange system comprising a set of columns arranged in a series packed with ion exchanger to be loaded and another series of columns containing ion exchanger to be regenerated, is characterized in that the series to be loaded is divided into two groups, the loading solution is passed through the two groups in succession, the solution discharged from the last column of the second group is freed by crystallization from a large part of the compound formed during loading, the mother lye is concentrated and returned to the first column of the second group.  The regenerating solution passes through the regenerating series of columns in such amount that regeneration is incomplete but a virtually pure regenerated solution leaves the last column.  In Fig. 1 the columns C1 to Cm and D1 to Dn constitute the first and second groups of the loading series.  The loading solution B2A2 is passed through the columns in succession and the solution leaving the last column of the second group is freed from the B1A2 compounds formed, by crystallization at Cr, and the residual lye is evaporated at Ev and returned to the first column of the second group, that is, D1.  The regeneration is shown in Fig. 2 where columns E1 to Ep are arranged in series and are transversed by the regenerating solution B1A1 the amount thereof being such that a virtually pure B2A1 solution leaves the last column.  Periodically the columns are disconnected and switched over so that the first column E1 in the regenerating group becomes the last column of the first loading group; at the same time column C1 is added to the end of the regeneration group and column D1 becomes column Cm, the cycle is then repeated.  The invention is illustrated by the production of potassium nitrate crystals and calcium chloride solution from calcium nitrate solution and potassium chloride solution, six columns in two groups of three being employed for loading and a single group of three for regenerating.  During loading the columns, saturated with potassium ions, are treated with a calcium nitrate solution passed therethrough, until the final column of the first group is 100 per cent. saturated with calcium ions.  After leaving the last column potassium nitrate is crystallized out and the residual lye returned to column D1. Regeneration is effected with potassium chloride solution to such an extent that the regenerated column is only 80 per cent. saturated with potassium ions.

Abstract: 554,735. Control systems for welding &c. WHITEHOUSE, H. Feb. 4, 1942, No. 1464. [Class 38 (iv)] Capacitative switching Control.-To . time the application of current in spot welding and for other purposes a sensitive relay SR in parallel with condensers 6 is energized and the condensers charged by the operation of a pushbutton switch 3. The relay controls a contactor R3 which closes the welding circuit. The relay SR de-energizes and causes interruption of the welding circuit when the condensers have discharged. The switch 3 energizes a relay R1 to establish at R1a the circuit through a condenser 4, of a relay R2 which thereby closes the circuit of the relay SR and condenser 6 until the condenser 4 has charged which normally occurs before the contactor R3 has opened a switch R3b. The operation cannot repeat during closure of switch 3 owing to the charge on condenser 4, which is eliminated only on release of the push button by closure of contacts R1a. The relay R2 has a back contact R2b which controls a high resistance discharge circuit for the condenser 6. The time of the weld &c. is the sum of the charging and discharging times of condensers 6, which is determined by adjustable resistance 5.

Title: Improvements in or relating to roll film cameras
IPC: G03B19/04
Filed: 1943-02-03
Abstract: 563,307. Roll-film cameras. KODAK, Ltd., and NAGEL, H. Feb. 3, 1943, No. 1797. [Classes 97 (i) and 98 (i)] A roll-film camera is provided with a resilient film-guiding member which-is secured at one end adjacent a fixed film guide and at the other end forms together with the film take-up core a narrow passage extending partly round the core which guides the leading end of the film so that, when the core is rotated, projections on it engage marginal perforations in the film and attach it to the core. As the film is wound on to the core, the adjacent free end of the resilient member yields outwardly. The invention is described as applied to a camera as described in Specification 563,304, the exposed film being wound into a detachable magazine formed by a cylindrical casing 13 with fixed and removable end walls 14, 15 respectively which is housed in a chamber D in the camera. The magazine contains a film core 24 having a serrated aperture in which engages. a square-section driving-spindle 11 forming part of the filmfeeding mechanism of the camera..The film F passes from the sprocket 4 between fixed guide plates 5, 6 and through a slot in the wall of the chamber D and a slot 27 in the wall of the magazine. In the latter it is guided by a resilient member formed by a pair of spring fingers 39 extending from adjacent one edge of the slot 27 and connected by a cross-member 39<1>. The ends of these fingers are curved to form a narrow passage round part of the core, in which teeth 42 on the core engage marginal perforations on the film, so automatically attaching it to the core. A second pair of spring fingers 43 extending from the other side of the slot 27 prevents the film coiling on itself and so failing to become connected to the core. The slot 27 is closable by a plate 28 slidably mounted between the wall of the magazine and a cover-plate 29, and operated by a projection 33. When the magazine is inserted in the camera the projection 33 slides into a groove 35 in the wall of the chamber D. The magazine is then locked by a partial rotation, which causes tongues 38 secured to it to engage under pins extending radially from the wall of the chamber D. During this movement the plate 28 is prevented from moving with the magazine by the projection 33 engaging the groove 35, so that the slot 27 is uncovered. Prior to removing the magazine the film is severed by means not shown, and partial rotation of the magazine to unlock it then causes the plate 28 to seal the slot 27 before withdrawal. Specification 563,308, in which film-severing means are described, is referred to.
