Abstract: 1,054,919. Siphon-discharged water wastepreventers; ventilating closets; closet seats. D. C. BAKER. April 12, 1965 [Jan. 12, 1964], No. 49219/63. Heading E1C. A siphon for a flushing cistern 1 has an outlet leg 7 connected with the flush water outlet 29, a branch duct 9 from the leg 7 connected to a water overflow hole at 13, to which an exhaust fan 10 in the cistern 1 is connected to draw polluted air from a water-closet bowl to expel it via the water overflow hole. Excess water passes through an inlet in a pipe 16 to the overflow hole. A pipe 32 connected to the outlet 29 leads to a closet bowl and within it is a pipe 35 separated from it by a gap and connected to the leg 7, the gap being connected by radial apertures 30 to the duct 9 to conduct such air thereto. The fan 10 is driven by an electric motor actuated by a switch 18 which is operable through pneumatic connection to the water-closet seat so that the fan 10 is started when the seat is depressed. Between the bowl and the seat, to which it is attached, is a container the internal volume of which can be reduced by pressing the seat down and communicating with a pneumatic operating chamber of the switch 18 through a conduit. The container is formed in a flexible rib, under and around the seat of hard plastics material and approximately constantly spaced from the bowl on occuping the seat. The conduit may be within the rib or may be a tube around it.
Patent GB-1069947-A (GB)
Abstract: 1,069,947. Counter units. CSF-COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Sept. 16, 1965 [Sept. 23, 1964], No. 39530/65. Heading G4D. [Also in Division G3] A counter unit comprises a board on which are metal studs, successively contacted by a brush carried on a shaft which is rotated when an electromagnet is energized by each input pulse. In the form shown the shaft (51, Fig. 4, not shown) is rotated by a paddle mechanism when an electromagnet 57 is energized by a switch 63 (Fig. 8) being closed by a cam wheel 64. The shaft 51, to which the brush is fixed rotates through one step when the magnet is energized and a second step when the magnet is de-energized so that one of the arms 46-49 of the brush engages first a stud (32) Fig. 1 (not shown), and then one of the number studs which are connected to the cathodes of an indicator tube. On the pulse after the arm rests on the ninth stud, one arm passes on to stud 33 which feeds a transfer pulse to the next decade. On the termination of this pulse the first arm leaves the stud 33 and a further arm engages the zero stud. A counter may be zeroized by "self-rotation" studs 20-28 by pressing a button 62 (Fig. 8) to by-pass the switch 63 so that the brush advances until an arm settles on the zero stud. An adaptation of the counting unit to form a clock is described in which, in the stage representing the tens of minutes, the studs 6-9 are interconnected. The stages counting the hours are also modified in that a transfer pulse is transmitted to the tens of hours unit not only at the tenth pulse but also at the fourth pulse. When a 1 is indicated in the tens of hours unit the latter pulse has no effect since the second transfer stud 87 is unconnected, but when a 2 is indicated one arm of the brush is on stud 87 so that a closed circuit is formed and the brush rotates past the studs representing 4 to 9 on the hour stage to zeroize it. The counting unit may be adapted to form a preselection counter in which the desired count, e.g. four, is entered on a keyboard (104, Fig. 10, not shown), the studs 20-28 being disconnected from each other and connected to the numbers of the keyboard. When a desired number is depressed, the corresponding stud (25) becomes isolated and one of the arms of the brush rides over the self-rotation studs until it contacts the stud (25) when it stops. Pulses are then fed to a counter until, on the fourth pulse one arm finishes its sweep of the number studs and a further arm leaves the ground area 102 so that a pulse is applied to a servo-mechanism 105. Several units may be used for preselecting a multi-digit number. A similar circuit may be used for the remote control of switches.

The piston may be a ball of rubber, plastics or metal and the duct may be of polyethylene, nylon, copper, steel or stainless steel. The liquid is preferably fed from a supply via a coil disposed in a refrigeration unit 1 to the inlet port, and the duet is also preferably within the unit. The duct, if remote from the unit, may be insulated in an insulated container, or it may be coaxial with and within a further duct with refrigerant gas being passed between the ducts. The tap 10 may be operated manually (as shown) pneumatically or electrically. A locking device 16 forced towards the valve member by liquid flowing through the inlet 11 engages with one or the other passage in the valve member to prevent operation of the tap during liquid flow. Disengagement of the locking device may be effected by the piston operating a switch or photo-electric cell. The piston when made of rubber or plastics may be filled with air, liquid, gas or sponge. Alternatively the piston may include a foam rubber body (19) with two rubber end seals (20, 21) (Fig. 4a, not shown), or a double ball (24) (Fig. 4c).
