Abstract: SELF MONITORING DOUBLE VALVE            ABSTRACT OF THE DISCLOSURE     A double valve of the safety type for the control of equipment such as the clutch/brake of a press. The double valve comprises two four-way valves each having two supply and two working ports and an exhaust port. The valves are shiftable by fluid controlled means through a shuttle check valve. The arrangement is such that when either main valve is faulted, pressure will be removed from the clutch/brake motor and the fluid controlled shifting means will be disenabled due to the lack of synchronism between the main valves. This self monitor-ing function will prevent repressurization of the clutch/brake motor regardless of whether the unfaulted main valve continues to operate. The main valves are of the open center crossover type to prevent trapping of air at the working port for the clutch/brake motor in intermediate positions of the valves. The self monitoring function is accomplished by connecting both sides of the shuttle check valve, which supplies the fluid controlled shifting means, to exhaust whenever a discrepant main valve position exists, thus insuring that both main valves can no longer be simultaneously shifted to their open positions until the fault is cured. A lockout and reset valve is also shown between the outlet of the shuttle valve and the pilot valves, which further inhibits operation after the system is disenabled until there is a manual reset.

Abstract: IMPROVEMENTS RELATING TO THE            TREATMENT OF FLAT GLASS          ABSTRACT OF THE DISCLOSURE      A method of treating flat glass to reduce its vulnerability to scratching, e.g. during storage and/or transit, wherein a transparent film of a cationic surface active agent is adsorbed on the glass by applying an aqueous solution of the surface active agent to the glass on the production line and drying the glass.  The treatment may be effected prior to processing such as toughening, bending or laminating of the glass.  The solution may be applied to the glass after it has been washed, near the end of the production line, using for example an anionic surface active agent as detergent.  Alternatively, a solution containing both a cationic surface active agent and an anionic surface active agent as detergent may be applied to the glass to wash it, followed by rinsing with water and drying.  The cationic surface active agent is preferably one which is positively charged in the aqueous solution e.g. a quaternary ammonium salt such as an alkyl dimethyl benzyl ammonium chloride.  A concentration of 0.001% to 2%, pref-erably of the order of 0.02%, of the cationic surface active agent may be used.  Apparatus for carrying out the treatment on the production line comprises means for sup-plying a solution of treatment agent to at least one major surface of the glass, a collector for collecting solution flowing from the glass, means for recycling at least a proportion of solution from the collector to the supply means and a reservoir arranged for connection to the supply means for holding fresh treatment solution and supplying it to the supply means.

Abstract: Kidney dialysis filters, or artificial kidneys, which contain a dialysis membrane mounted inside a housing and separating the housing into a blood side compartment and dialysate side compartment are washed for reuse by a process in which washing water is supplied to the blood side through an inlet hose, and exists through a remote, resiliently expandable and contractable outlet hose to a drain. After flushing of the blood side by water flow in this manner, the outlet is closed whilst continuing washing fluid feed, to build up fluid pressure inside the blood compartment, and then the fluid feed is interrupted. A drain in the inlet conduit is then opened to cause brief reversal of flow of fluid within the blood side, due to relaxation of the membrane and the outlet hose to relieve the fluid pressure. Then steady flow of fluid is resumed. This brief reversal of flow causes a fluid action to dislodge contaminating blood particles from the membrane and elsewhere, but without risk of depositing these blood particles in a portion of the apparatus where they could later contaminate an artificial kidney subsequently washed using the apparatus. The rate of pressure drop in the blood compartment can be measured and used to determine the extent of obstruction of the blood compartment.
