Title: Improvements in or relating to automatically controlled sheet feeding mechanism
IPC: B65H5/34
Filed: 1932-02-09
Abstract: 384,476. Feeding sheets ; folding paper. CAMCO (MACHINERY), Ltd., 63, Farringdon Street, and DAWSON, J. C., Lauriston, Vivian Avenue, Hendon, both in London. Feb. 9, 1932, No. 3875. [Classes 100 (i) and 100 (ii).] Sheets are fed to sheet-operating machines by mechanism which can by a suitable preadjustment be set to advance the sheets continuously in an untimed manner or to advance the sheets intermittently in a manner which is timed in accordance with the particular machines which are operating upon the same. The invention is especially applicable to mixed folders in which the sheets may pass to a buckling folder 10 with a plurality of fold plates 11 for producing one or more parallel folds, and additionally or alternatively to a reciprocating blade folder C with one of more knives for producing perpendicular folds. The sheets are fed from a pile 14 to a feed table B by means of a rotating and suction-head 16 which is operated as described in Specification 244,402, [Class 100 (i), Feeding and delivering webs &c.], to advance the sheets in succession when the suction-head is put in communication with a main suction pipe 21 by means of a valvecontrolled chest 20. The pipe 21 is connected to a suction pump 22, and the air pressure in the pipe 21 may be controlled by a handoperated relief valve 24, or by a valve 27 which is controlled by a cam 34 which is set to a predetermined position in order to control the feeding of the sheets. The cam 34 can be connected to or disconnected from the shaft 17 of the suction-head 16 by means of a spring- pressed plunger 36, mounted in an arm 35 on the shaft 17, and adapted to be engaged in one of three holes 38 in the cam 34 or to be held out of engagement with the cam. In the latter case the cam 34 permits the valve stem 28 of the valve 27 to be maintained continuously in raised position by a spring 30, and the sheets are advanced in untimed relation to the buckling folders only. If the sheets require to be folded by the blade folders C, the plunger 36 is engaged in one of the holes 38 and the cam 34 rotates with the shaft 17, and the sheets are then advanced in timed relation. The timing is varied in accordance with the number of buckle folders which are used before the knife folders act upon the sheets. The pile table 15 is raised automatically in known manner by means of screw-and-nut mechanism 40 controlled by a feeler on the pile and linkage 50 controlling a ratchet guard 43 which governs the action of a pawl 45 on a ratchet wheel which operates the screw-and-nut mechanism by means of bevel gearing. The pawl 45 is carried by a lever 44 and rod 46 oscillated by a crank 47 driven from the shaft 17 of the suction-head 16.

Title: Improvements in and relating to a process and apparatus for light-signalling by wireless radiations of short wavelength
IPC: G08C17/00
Filed: 1940-03-04
Abstract: 536,042. Radio signalling; discharge lamps. MOLINA, E., and DESMIDT, D. March 4, 1940, No. 4042. [Classes 39 (i) and 40 (v)] [Also in Groups XXXVIII and XI] Relates to a method of signalling in which wireless signals of predetermined wavelength bring a luminous signalling device into action. According to the invention, the signals are given by an electric discharge lampoperated by a lowtension battery and an induction coil, the coil being brought into action when a relay is energised by the increased output of the wireless receiver. A beacon for an aerodrome comprises a casing 1, Fig. 1, at the top of which is a helicoidal discharge tube 2 protected by a transparent dome 4 in a hinged cover 3. The casing contains a wireless receiver 6, Fig. 2, with a high-tension battery 7, a low-tension battery 8, and an aerial 9. A switch 10 puts the battery 8 into circuit. A relay, not shown, is energised by the increased current resulting from the reception by the receiver of a suitably tuned transmission, and connects the terminals 11, 111, to put a motor 12 into circuit with the battery 8. The motor rotates a suitable switch 17 which is in series with the primary winding of an induction coil 20 and a trembler or interrupter 18, the secondary coil being connected with the discharge tube 2. The switch 17 may be constructed to interrupt the circuit periodically into periods representing code letters, so that the tube 2 glows and is extinguished in conformity with the periods regulated by the switch 17. The switch may be short circuited by another switch 25 to cause the tube 2 to be illuminated continuously when required, or a Morse key may be used to enable the tube to be flashed to signal a message. The transmitter may be carried by an aircraft when the beacon is placed on the landing ground so that operation of the transmitter automatically produces a predetermined signal from the ground. Conversely, the receiver may be placed on an aircraft while the transmitter is used on the ground. The beacon also may be placed on a ship or used on a buoy. The discharge tube 2 contains a number of cylindrical or spherical bodies 5, Fig. 4, which are perforated, and the perforations of adjacent bodies are arranged out of alignment with one another to increase the distance from which the light is visible.

Title: A process for the preparation of acid-free aqueous hydrogen peroxide
IPC: B01J41/04
Filed: 1959-02-09
Abstract: Aqueous hydrogen peroxide solutions are rendered acid free by passage through an anion exchange resin in bicarbonate salt form. Aqueous solutions containing preferably not more than 50% wt. H2O2 and acid impurities e.g. phosphoric, sulphuric, nitric, tungstic, organic carboxylic say formic, acetic or peracetic, or organic sulphonic acids and especially those solutions which are 0.01N-0.1N with respect to the acid impurities, are contacted at a temperature below 80 DEG C., preferably between 10-25 DEG C. with an anion exchange resin preferably a strong base resin of the quaternary ammonium salt type e.g. trimethyl benzyl ammonium poly (styrenedivinyl benzene), in the bicarbonate salt form.  The resin may be slurried with the solution to be purified or may be used in particulate form as a bed through which the solution is passed by either upward or downward flow.  When employing a bed of resin, to avoid channelling caused by the upward passage of gases produced by the reaction of the solution with the resin e.g. CO2 and O2 the purification may be carried out at such a pressure that the CO2 remains dissolved in solution or the solution may be dispersed over the bed of resin as a down flowing stream using a gas inert under the reaction conditions e.g. air or N2 as a dispersing agent or the bed may be operated under flooded conditions using a rate of flow of solution such that gases present on the bed are swept down through the bed.  The pH of the solution as measured in the purified effluent from the resin slurry or bed is preferably maintained between 3-8 especially 4-6.5 and may be controlled by regulation of the partial pressure of CO2 in the system.  Such CO2 may be that evolved by the reaction of the resin with the acid impurities in the solution alone or preferably may be supplemented by addition of CO2 from other sources which may be bubbled through the resin slurry or mixed with the inert dispersing gas.  Contact times of 10 seconds to 1 hour are specified 1/2 -15 minutes being preferred.  The resin may be regenerated by treatment with a solution of a bicarbonate salt, by treatment with a base and thereafter with a solution of carbonic p  acid or preferably by treatment with a solution of sodium carbonate followed by washing with CO2 and water. Specifications 540,534, 654,706, 695,325 and 708,339 are referred to.
