Title: Power unit, particularly for windscreen wipers
IPC: B60S1/26
Filed: 1946-09-04
Abstract: 621,582. Windscreen-cleaners. O'SHEI, W. E. Sept. 4. 1946, No. 26584. [Class 138(i)]  [Also in Groups XXVI, XXXV and XXXVII] A power unit for actuating windscreencleaners comprises electric driving means and vacuum driving means for simultane-- ously driving the wiper blade or blades. The unit may take the form of a suction motor acting as a booster for the electric driving means which maintain the unit running during those periods when the suction is insufficient to drive the suction motor. As shown in Fig. 1, a suction motor 1 and electric motor 2 are provided with a common driving shaft 3, and the control valve 4 for the motor 1 is mechanically coupled with the switch 5 controlling the motor 2; if desired, the operation of the valve 4 to stop the motor 1 may apply suction to one side of this motor for the purpose of parking the blade. In a modification, the valve 4 and switch 5 are not directly coupled, but the shaft 3 carries a cam for operating the switch 5 so that the latter is opened when the valve 4 is operated to stop the motor 1 and move the blade to parking position; the coupling between the motor 2 and shaft 3 includes a lost-motion connection whereby the movement of the shaft to parking position does not affect the motor 2. In a further modification, the cleaner is driven by a combined suction and electric motor as shown in Fig. 3, the central cylindrical section 29 of which is a fluid motor constructed as described in Specification 557,232, [Group XXVI], and provided with tubular extensions 31, 32 co-operating with solenoids 35, 36 ; these solenoids are controlled by switches 37, 38 associated with the ears 39, 40 of the valve 41 of the fluid motor. The application of suction to opposite ends of the suction motor energizes the corresponding solenoid so as to assist the action of the suction, and, in the event of the suction falling, the motor continues to operate under the action of the solenoids. In an alternative construction, two cleaners 50, 51, Fig. 4, are driven through pinions 52, 53 from a rack 54 which is driven by an electric motor 55 and a suction motor 57 ; the motor 57 is remotely controlled by a valve 59 associated with a switch 60 for controlling the motor 57 so that, when the switch 60 is opened, suction is fed to one side of the motor 57 in order to park the blades. Specifications 535,419, 546,483 and 557,377, [all in Group XXVI], are referred to.

In the arrangement of Fig. 2 (not shown), two concentric conductors are provided each with its own polyamide sheath. The ends of the polyamide sleeves may be anchored to insulating sleeves on the cable terminals to stop them moving back with respect to the braided conductor.

Title: Improvements in or relating to the adsorption of bromine from aqueous brines
IPC: B01J41/04
Filed: 1961-07-24
Abstract: Bromine is adsorbed on a strong base anion-exchange resin from a bromine-containing aqueous brine in the presence of 0.2 to 2.0 mols. of excess free chlorine per mol. Br2.  The process may be applied to natural or synthetic brines.  Natural brines may contain 50-7,000 p.p.m. bromide and have a chloride : bromide ratio of 20 : 1 to 500 : 1.  Synthetic brines may contain HCl or chloride of Li, Na, K, Rb, Cs, Mg, Ca, Sr or Ba.  A temperature between the freezing point of the solution and 60 DEG  C. is chosen. The incoming brine is settled, screened and brought to a pH less than 7, e.g. less than 5, by a strong acid, e.g. hydrochloric, hydrobromic, sulphuric, phosphoric, nitric or trifluoracetic acid or mixtures of the same. Chlorine is added, in excess to the quantity required to liberate the Br2, as a solution in brine or as a hypochlorite or chlorate solution. The solution thus obtained is passed through a resin bed (countercurrent process) or mixed with resin (cocurrent process).  In the latter case the brine, acid, resin and Cl2 solution may be mixed separately or together in any order. The free halogen molecules are adsorbed on the resin as monovalent anious BrnXmwhere X is Br or Cl and n and m are small integers whose sum is odd.  When the flow has been stopped the adsorbed halogen is reduced by SO2 and the resin is drained. Adsorbed bromide ions are removed by passage of a saturated aqueous NaCl solution through the resin and these washings are added to the SO2-reduced solution.  Oxidation by Cl2 liberates Br2 which is stripped from the solution by known means. The residual solution contains HCl and H2SO4 and is used to acidify fresh incoming solutions. Typical resins used in this process are based on the polystyrene backbone with divinyl benzene cross-linkages.  The fixed cationic sites are quaternary ammonium groups of the formula <FORM:0991610/C1/1> where R1, R2 and R3 are alkyl, alkylol or form a heterocyyclic radical based on the N atom. Electrical neutrality is conferred by one of a large number of specified acid radicals. The resin has a particle size of 16-400 mesh. Specifications 654,706, 679,850, 679,852, 679,853, 683,400 and 718,308 are referred to.

Abstract: 965,296. Fluid-pressure servomotor systems. JOSEPH LUCAS (INDUSTRIES) Ltd. July 19, 1962 [July 27, 1961], No. 27213/61. Heading G3P. [Also in Division F2] Each of a pair of vehicle wheels 3, 4, are driven by variable-stroke hydraulic swash-plate motors 1, 2 fed by an engine driven pump 5, which may also be of the swash-plate type. The motor swash-plates 15, 16 are each adjusted by a separate ram 13, 14 connected to the pump supply or return 5 under the control of valves 18,19, respectively. The valves are urged in one direction by springs 20, 21 acting through wedges 22, 23, each of the latter being connected to the swash-plate of its associated motor to provide a follow-up action; the valves are movable in opposition to the springs by a piston 25 subjected to pump output pressure and acting upon a plate 24 against which both valves abut. If the load on the wheels increases both valves are lifted to vent the rams and increase the strokes of the motors the wedges being moved outwardly to restore the valves to their original lapped positions. The converse applies should the load at the wheels be reduced. If the stroke of one motor differs from the other then the associated wedge is moved laterally to alter the position of its valve so rocking the plate 24 and adjusting the other valve until both motors again have the same stroke.

Title: Improvements in and relating to electromagnetic counting means

IPC: G06M1/10
Filed: 1956-09-06
Abstract: 789,506. Counting-apparatus. ERICSSON TELEPHONES, Ltd. Sept. 6, 1956, No. 27276/56. Class 106 (1). In an electromagnetic counting apparatus comprising at least two electromagnetic step-by-step switching devices means are provided for summing separately signals indicative of two conditions and differencing the totals. An embodiment for counts up to value 4 is shown in Fig. 1. Closure of contacts X causes a pulse, which is to be added, to operate the relay PA. Contacts PA1 close, causing relay A to be energized whereupon contact A2 energizes the driving magnet ADDM of the selecting switch AD. This causes the interrupting springs ADdm, if contacts X have opened, to release the relay PA, whereupon contacts PA1 open releasing relay A and the original state is regained, the wipers on the five banks a to e of the switch AD having moved forward one place. Similarly closure of contacts Y cause a pulse which is to be subtracted, to actuate the relay PS, and wiper of switch SB to move forward one place. The connections of lamps L0 to L4 are arranged so that the appropriate lamp is illuminated to indicate the difference between the number of X-pulses and the number of Y-pulses. The connection of the similar arrangement of Fig. 2 by joining 6 to 7 and 8 to 9 and the addition of further relay contacts as shown A3, S3, enable counts up to 24 to be dealt with. When L4 is illuminated a further pulse from X causes contacts A3 to close and send a pulse via 8 and 9 to the relay JK which corresponds to the relay PA, and when L0 is illuminated a further pulse from Y causes contacts S3 to send a pulse via 6 and 7 to the relay GH which corresponds to PS. The connection of relays V and T as shown enables an alarm bell ALB to be rung and a lamp ALP to be illuminated when a predetermined difference total is attained. The pulses to be counted may be of different polarity indicative respectively of the two conditions and applied to particular relays by asymmetrical conducting elements. Switches with other pluralities of bank contacts may be employed. The apparatus will indicate the correct difference total whether this be positive or negative. The apparatus may be employed for counting the number of persons both entering and leaving an enclosure, and for displaying visually the net total of persons within the enclosure.
