Title: Apparatus for the treatment of waste water
Inventor: JERVSTRAT G
IPC: C02F3/08
Filed: 1975-02-12
Abstract: 1480126 Waste water treating apparatus PARCA-NORRAHAMMAR AB 12 Feb 1975 [14 Feb 1974] 5909/75 Heading B1C Apparatus for treating waste water comprises a shell 5 with inlets for air and water at one end and an outlet 28 at the other, and discs 14, 15 having alternate central 19 and peripheral 20 openings so that the air and water take a sinuous course through the shell and the surfaces of the discs are alternately exposed to air and water whereby a biological fuzz is built up in them. As shown the shell 5 is a drum rotating with the discs but it may be stationary. Air is introduced by a pump 32 and water by a pump or by entry through openings 27 when they are immersed. It is thence conducted to the centre of the drum by one or more spiral surfaces 24 and enters through opening 19, surplus water returning to the basin through an outlet 29. The level in the drum is determined by the size of the outlet 28. The discs may have parallel straight corrugations and be assembled with the corrugations mutually inclined to provide a diamond-pattern of generally radial channels 16 between them (see Figs 4 and 5, not shown). In another arrangement (see Fig. 6, not shown) the discs 14, 15 may be separated by discs (37) having both central and peripheral openings. The apparatus may be supported by a float (12, Fig. I not shown) on the surface of the waste water.

Title: Improvements in or relating to apparatus for lifting or transferring a liquid to a receptacle wherein it maintains a constant level
IPC: F02M37/02
Filed: 1919-03-11
Abstract: 142,245. Neate, P. J. March 11, 1919. Feed-water, supplying and controlling.-Apparatus for lifting or transferring a liquid to a receptacle wherein it maintains a constant level comprises a feed chamber 2 connected by a pipe 4 to a liquid reservoir and by a valved pipe 34 to the constant-level chamber 1 placed below it. The chamber 2 is connected to a suction device by a passage 16 controlled by a valve 17 carried by a float 6, and to the vessel 1 by a pipe 21 controlled by a valve 26. When the liquid rises in the chamber 2, the float 6 rises and, by means of pins 30 and a plate 31 carrying a projection 33, opens the valve 26 before the valve 17 closes the suction passage. Air &c. then flows from the chamber 1 into the chamber 2, and the liquid passes from the chamber 2 to the chamber 1. When the liquid seals the end of the pipe 21, communication between the chambers is cut off and the float sinks and opens the valve 17 and closes the valve 16. The chamber 2 fills again, but no flow to the vessel 1 occurs until the level of liquid falls below the end of the pipe 21. The non-return valve 42 on the pipe 4 may be engaged by a pivoted member 37, so that, when the apparatus is mounbed on a vehicle going downhill, the closing pressure on the valve is increased. The vessel 1 is connected by pipes 36 to a carburettor &c.
Patent GB-1425991-A (GB)
Title: Heat-recoverable closure member
IPC: B65D39/02
Filed: 1973-02-07
Abstract: 1425991 Heat recoverable closure members RAYCHEM CORP 7 Feb 1973 [4 Jan 1973] 6083/73 Heading B3A [Also in Divisions C2 and C7] A method of closing an aperture 2, Fig. 1, wherein a heat-recoverable disc 1 made from a memory metal which has been deformed from a flat configuration and which is capable of recover-  ing towards its flat configuration on being warmed above the transition temperature of the memory metal is inserted into the aperture and then warmed above the transition temperature to close the aperture. The disc 1, is made of Ni-Ti alloy containing 47À1% Ni, 49À4% Ti and 3À5% Fe and has a transition temperature of about -125 C. The disc is cooled to -196 C. in liquid nitrogen and deformed in a press. When warmed to room temperature the disc material undergoes transition from a martensitic to an austenitic phase and the dished disc attempts to revert to its original flat configuration, thus expanding in diameter. Since the aperture 2 in plate 3 is of smaller diameter than the disc in its flat configuration, the aperture is completely sealed. The outer edge (10), Fig. 2 (not shown), of the disc may be provided with grooves, ridges or teeth by machining to aid the sealing. A forming die 5, Fig. 3, made of plastics or metal, can be removably attached, e.g. using glue, to the disc 4, and has a lip 6 to aid in accurate locating within the aperture 2. After insertion into the aperture of the deformed disc and warming the disc the die is removed. A member (8), Fig. 5 (not shown), may be removably attached to a disc (7), a lip (9) aiding accurate positioning in the aperture. A lip on die 5 and member (8) may be dispensed with by counterboring or countersinking the aperture to produce a continuous or discontinuous lip (11) on the aperture. When the disc is inserted in the aperture of a pressure vessel the convex surface of the disc faces the interior of the vessel so that the sealing forces will increase with the application of pressure as well as the forces due to thermal recovery of the disc. The disc may be perforated and/or of irregular configuration.

Title: Improvements in collapsible perambulators or push-chairs
IPC: B62B7/10
Filed: 1944-04-03
Abstract: 577,051. Collapsable push-chairs. BLANEY, A. M., and GROGAN, H. O. April 3, 1944, No. 6159. [Class 108 (i)] In a push chair collapsable to a box-like structure resembling a suit-case, the seat framework of the chassis comprises two side bearers 1 integral with a well 44 for storing an apron and hood. Links 2, 3 are pivoted to the bearers 1, and 4, 5 to the links 2, 3, while a link 6 connects the pairs of upper and lower links. A link 45 connects link 5 to the bearer 1, and a wheel support 8 is pivoted to the links 4, 5. Slotted extensions 9 of the support 8 receive wheel axles 10. Arms 12 pivoted to the bearer 1 are slotted at 13 to receive the axles 10 and are connected by a tension spring 14. Links 15 pivoted on the arms 12 are adapted to slide along bearers 1 under the action of compression springs 16. A bell crank lever 19, 21 pivoted to the frame has its short arm 19 connected by a link 20 to the common pivot of links 2, 4, 6, while the long arm 21 supports the main back rest 22 which is in two parts hinged together. An additional back rest 24 is hinged at 48 to the back rest 22 and depends downwardly over it. The arm 21 is pivoted to a U-shaped handle 25 held in extended position by a catch having a hook 33 engaging a projection 34 on the upholstered side member 35 which is pivoted to the bearer 1. The side members 35 are maintained in opened position by arms 36 pivoted at 38. A step 41 is supported by bars 39, 40, 42, the latter having a straight end portion adapted to slide parallel to the bearer 1, and provided with a hook which is engaged by arm 19 in the closed position of the chair. The collapse of the push chair is effected by disengaging the hook 33 and pressing the handle 25 rearwardly to actuate links 20, 6 forwardly. The links 2, 3 and 4, 5 are caused to close together and draw up the wheel support 8, the wheel axles 10 moving in the slots 13 in arms 12, which remain materially in the same position relatively to the frame. The axles 10 move along slots 9 till the wheels touch, when the arm 21 is pointing downwards. The rigid connection between arm 21 and handle 25 is then released, and handle 25 rotated through a right angle. The back rests 22, 24 follow arm 21 into the collapsed position and form two sides of a container for the push chair. Bar 42 is pushed rearwardly until the step 41 is pulled against bar 39 and forms a third side of the container. The two sides of the body are swung down in their own planes to form a fourth and fifth side of the container, and the sixth side is formed by the seat.

Title: Improvements in electric motors and switchgear therefor
IPC: H02P7/18
Filed: 1924-03-11
Abstract: 234,566. Stirk, J. G. March 11, 1924. Travelling a fixed distance.-To obtain definite intermittent movements through fractional parts of a revolution, a motor has its armature C tapped at two points and the tappings connected to slip-rings and brushes H, which are connected to the commutator brushes I in definite angularpositions by a rotary brush switch D, F in combination with an electromagnet switch G. The effect is that when the operator closes a hand switch A, the motor armature receives current from the power lines M and proceeds to revolve in the usual manner, but on reaching the determined angular position converts itself into an electromagnet which comes to rest opposite one of the poles of the field magnet Y. When the operator opens the switch A, the switch G breaks connection between the commutator brushes and the tapping slip-rings, so that on the reclosure of the operator's switch, the motor moves on a further step.

Title: Improvements in or relating to cut-out or unloading valves
Inventor: GROVES WALTER ROBERT
IPC: F16K17/04
Filed: 1949-03-07
Abstract: 670,178. Fluid-actuated valves. BRITISH INDUSTRIAL PLASTICS, Ltd. March 2, 1950 [March 7, 1949], No. 6197/49. Class 135. In a relief valve of the kind described in Specification 567,645 the pressure fluid,after passing the partially open main valve to act on the larger of the two pistons and effect wide and quick opening of the valve, acts directly on this piston, instead of first passing through a tubular member, to effect a speedier unloading of the pump. As shown, the main valve 7 coacting with a seat 8 to control a port 4 is connected by a stem 10 to a small piston 12 of diameter equal to that of the port 4 and abuts a large piston 15 loaded by a spring 16 and slidable in a cylinder 14. An exhaust duct 24 having a valve 21 loaded by a light spring and having a leak aperture 23 therethrough has a connection 25 to the underside of the piston 15. Pressure fluid from the pump enters the casing through a connection 2 and passes a non- return valve 5 to supply the system through a connection 3 and act on the upper face of the piston 12 through a passage 13. When the pressure in the system exceeds a value determined by the spring 16, the piston 12 is urged down to partially open the main valve 7 causing a fall of pressure on the upstream side of the valve 5 which then closes and allows pressure fluid to act on the piston 15 which instantaneously effects full opening of the valve 7. As soon as the system pressure falls below its predetermined minimum value, the spring 16 overcomes the system pressure acting on the upper face of the piston 12 and the differential pressure acting on the piston 15 to close the valve 7. In a modification, the spring acting on the valve 21 is replaced by an adjustment screw to permit a fixed but adjustable throttling past the valve 21.

Title: Improvements in or relating to protective systems for groups of rotary electrical machines
IPC: H02H7/06
Filed: 1926-03-05
Abstract: 270,043. General Electric Co., Ltd., and Angold, A. E. March 5, 1926. Protective arrangements for a number of generators supplying a load in parallel serve, on overload on any generator, to insert a limiting resistance simultaneously in the individual circuits of all the generators, such resistances being removed, simultaneously, only when\ the overload has disappeared from all the generators. The invention is shown as applied to two D.C. generators 1, 2 supplying the bus-bars 6, 7 in parallel through main switches 3, 4 and 8, 9 and through limiting resistances 11, 12 and 13, 14, one in each pole adapted to be short-circuited, simultaneously, by the contact-members 35 - - 38 when the winding 16 is energized. When the main switches 3, 4, 6, 7 are closed auxiliary switches 19 - - 22 are freed, and under the action of springs 27 these switches closely slowly due to the retardation of dashpots and an energizing circuit is completed through each pair of auxiliary switches from the bus-bars to a relay 18 through a resistance 30. When this relay closes it completes the supply circuit for the operating winding 16. If an overload appears on either generator circuit an overload relay 33 or 34 operates to short-circuit the winding 18, whereupon the operating winding 16 is de-energixed and all the limiting resistances are inserted. Since an overload on either generator serves to short-circuit the relav 18. the overload must disappear from both before the limiting resistances are again short-circuited.

Abstract: 886,775. Valves. U.S. INDUSTRIES Inc. Feb. 23, 1960, No. 6324/60. Class 135. An automatic shut - off valve has a plunger 28, Fig. 2, movable into a space 26, Fig. 1, laterally of a flow passage 4, 5 to move a valve 8 of the space into the passage where it closes on seats 6 or 7, the plunger having one end exposed to pressure in the space urging it out of the space, an oppositely facing surface, at the top of piston 33, of area equal to the exposed end and means, e.g. plunger passage 39 for applying the space pressure to the oppositely facing surface to balance the plunger, and a second oppositely facing surface, at the top of plunger 28 in chamber 42 to receive an actuating force for moving the plunger into the space. The ball valve 8 is moved to open the valve by hand wheel 24 and screwed spindle 14 until it is gripped by fingers 27. An external control pressure at 40, 42 acts on the second surface. The plunger 28 is also balanced with respect to a control pressure at 40, 42 acting on the second surface and via plunger passage 43 on an equal area surface at the bottom of piston 33. Should the control pressure fall below a predetermined value, spring 53 moves a plunger 48 having one end exposed to the control pressure in chamber 42, downwards to push the valve, via plunger 28, into closed position. Should the control pressure rise above a predetermined value, plunger 48 is moved up against stop 50, and the pressure acts via a second plunger passage 68 on top of a piston 59 to move the second plunger down against spring 65 to close the valve. In a second embodiment in Fig. 3, in addition to the previous action of plunger 28, should the pressure in the valve space 28 increase above a certain value, it acts via a passage 175 on a shoulder 152 on a plunger 151 exposed at its lower end to the space pressure and moves down against spring 176, entraining plunger 128 through members 181, 183 to close valve 108. In a third embodiment (Fig. 4, not shown), the plunger 151 closes the valve if the space pressure decreases below a certain value. In a fourth embodiment (Fig. 5, not shown), the plunger and springs are arranged so that the valve closes when the control pressure at 40 decreases and when the space pressure decreases or increases above predetermined values, and in a fifth embodiment (Fig. 6, not shown), the valve closes for an increase in control pressure and for increase or decrease in space pressure.
