Filed: 1971-11-02
Abstract: 1375831 Valves E J CLERK 2 Nov 1971 [9 Nov 1970] 53158/70 Heading F2V A valve for controlling the quantity of liquid discharged from a tank or cistern 1, comprises a ball or float 5 acting as a closure member for a discharge outlet 2 of the cistern, the float 5 having means for reducing its buoyancy so that, after opening, it automatically closes the outlet 2 earlier. The float has a lower aperture 10, and an upper aperture 8 closed by a valve element 17 to trap air within the float. A slotted tubular housing 11 fixed to the float 5 receives an actuating rod 18 for the element 17. The assembly of float 5, housing 11 and element 17 is associated with two independently-operable actuating levers 20, 26. Pivotal movement of lever 26 raises the whole assembly and allows a maximum quantity of liquid to flow from the cistern before the assembly automatically returns to its closed position. Alternatively, pivotal movement of lever 20 initially raises the element 17 until it abuts annular member 25, whereafter the whole assembly is raised by continued movement of lever 20. Thus the air is released from the float, resulting in earlier return of the float to the closed position.

Title: Converter circuits
IPC: H02M3/335
Filed: 1971-11-22
Abstract: 1366512 Pulse oscillator circuits HEWLETTPACKARD CO 22 Nov 1971 [14 Dec 1970] 54153/71 Heading H3T [Also in Division H2] An oscillator comprises an amplifier 9 having its output connected to a load 13 and to a feedback transformer 11 having a tertiary winding 25 connected to a saturation control circuit and a secondary winding connected to the input of the amplifier in series with a capacitor 22, a diode 18 being connected across the amplifier input to conduct for inputs of the reverse polarity to that which drives the transformer towards saturation. In operation, current builds up in transformer 11 until the core saturates and causes the amplifier to switch off. Reverse current then flows in secondary winding 17 and diode 18 and charges charge capacitor 22. The core is thus reset and the voltage across the capacitor turns on the amplifier to start a new cycle. The circuit is used to charge a capacitor 35 during the fly-back to provide a D.C. supply. The voltage of this supply is stabilized by comparing it at 27 with a reference and using the difference to control the reset level of the transformer core and thus the output pulse width.

IPC: B07B4/02
Filed: 1966-12-05
Abstract: 1,164,266. Separators. WHEELABRATOR CORP. 5 Dec., 1966 [17 Jan., 1966], No. 54342/66. Heading B2H. In an apparatus for separating, e.g. abrasive blasting particles from an abrasive-contaminant mixture, the mixture is fed to one end of a rotary screening drum 24 by means of a feed screw 32. The coarse material is discharged at the other end of the drum into a chute while the rest of the mixture which has passed through the drum falls into a hopper 38, 44 on to a bottom plate 40 which is provided with a lip 42 from which the mixture falls by gravity as a curtain. An adjustable baffle plate 46 and a swing gate 50 controlled by adjustable counter weights 56 ensure a uniform distribution of the mixture and regulate the flow thereof over the lip 42 to provide a curtain of falling mixture of uniform thickness, the mixture being urged forward by a helix 76 mounted exteriorly of the drum. An air stream 62 drawn or blown through a gap 64 between the lip 42 and a separator plate 58 passes through the curtain of falling mixture thereby removing therefrom the light contaminants which are discharged via a chute 68 into a passage 70, the air flowing through a passage 66a to an outlet 66. The air pressure may be varied by means of a damper in the passage 66a. The rest of the mixture falls into another hopper 80, 96 and overflows a lip 84 at the bottom thereof. A helix 98 mounted on a rotatable shaft 100 serves to urge the mixture forward while an adjustable baffle plate and a swing gate 86 perform the same functions as before. The curtain of material falling from the lip 84 across a gap 106 between the lip 84 and a further separator plate 104 is again subjected to a transverse stream of air, but at a pressure lower than that of the stream 62, for the removal of any remaining light contaminants which are discharged through a chute 106, the air flowing to an outlet 108 provided with a damper 109. The abrasive particles passing rearwardly of the separator plate 104 are directed by means of a diverter plate 120 into either a compartment 116 for storage and reuse or into a compartment 118 from which it can be recycled through the apparatus for further cleaning. In a modification, the helix 98 may be dispensed with. In a further modification, the plate 96 may be dispensed with, the falling material being received directly onto the plate 80 and lip 84.
