Abstract: 1418203 Treating sewage ATLAS AS 24 April 1973 [28 Aug 1972] 19352/73 Heading B1D [Also in Division Cl] An apparatus for the treatment of domestic and industrial sewage in order to reduce its biological oxygen demand, in which apparatus the sewage is separated by mechanical separating means into a solid phase and a liquid phase and the liquid phase is treated with a chemical precipitant, is characterised in that the mechanical separating means is an inclined strainer (2), the upper edge (3) of which is adjacent a raw sewage inlet and from the lower edge (5) of which a passage (4) to a sump tank (30) leads, the area below the strainer being part of a mixing tank (16) comprising a mixer (8) and dosage means (10) for the chemical precipitant, the lower part of the mixing tank being connected to an inclined, sedimentation tank (19) having an outlet (24) for purified water with pumping means (21) and a connection (28) from the lower part to the sump tank. The strainer is preferably a curved strainer and the mixing tank may be divided into 2 compartments connected through a small opening (15) near the bottom, the first compartment, placed below the strainer, containing the dosage means for the chemical precipitant and the mixer, and the second compartment (16) being connected with the sedimentation tank. An overflow (17) may be provided in the wall (14) between the 2 compartments to deal with peak loadings. In the embodiment shown, which has parallel flow in the sedimentation tank, the second compartment is connected with the sedimentation tank by a channel 18 and the sedimentation tank has inclined baffle plates (27) to improve sedimentation. Air is excluded from the tank by means of an air trap at the top of the tank connected to the pumping means (21). Water under pressure may be supplied by the pumping means (21) to the bottom of the tank (19) at (31) and to the connection (28) at (32) in order to adjust the viscosity of the precipitated matter for easy transfer. In a second embodiment, Figure 2, (not shown), countercurrent flow in the sedimentation tank is obtained by having the tank connected directly to the second compartment (16) and having the top of the tank connected to the pumping means (21).

Title: Means for feeding flat articles to several packing machines
IPC: B65B57/14
Filed: 1964-05-08
Abstract: 1,043,904. Endless conveyer. " SAPAL"  S. A. DES PLIEUSES AUTOMATIQUES. May 8, 1964 [May 9, 1963], No. 19375/64. Heading B8A. Chocolate tablets on a conveyer belt 2a are conveyed to a transversely disposed conveyer belt 4a or to a continuation 2b of the belt 2a, according to the position of an endless belt 6. The latter is movable between its two positions by a piston 10 controlled by a solenoid-operated valve 11. Switches 13 and 14 in series between power terminals 12 and the solenoids of the valve 11 are in the position shown, when photoelectric gates 16 and 17 are both unobstructed by a row of tablets. When the gate 16 is obstructed, switch 13 is thereby moved from its lower contact (shown) to an upper contact. This connects the power supply to the respective coil on one or other side of the valve 11 according to position of a series switch x. If the gate 17 is unobstructed, the switch 14 will be connected to its lower contact corresponding to movement of the solenoid valve in a sense to lifting the belt 6 to its upper position. Thus the belt 6 will remain in the upper position, if already there, or will move to this position if initially in the lower position, i.e. in either case the row of tablets obstructing the gate 16 will be delivered to the belt 4a. If, however, the gate 17 is obstructed, the row will be delivered to the belt 2b. A further gate 40 ensures that the belt 4a is momentarily stationary when a row of tablets is delivered to it. The belt 2b leads to a series of devices identical with that above described for feeding to respective packing machines. In a modification (Figs. 12-16, not shown), the switches 13, 14 are replaced by a single switch associated with a solenoid valve having a single solenoid.

Title: Fluid flow control valve mechanism
Inventor: BOTT WILLIAM J
IPC: B64D39/00
Filed: 1957-06-21
Abstract: 865,716. Fluid-pressure servomotor control systems. PARKER-HANNIFIN CORPORATION. June 21, 1957, No. 19540/57. Class 135. A pilot-operated diaphragm shut-off valve for controlling the supply of liquid, e.g. fuel, under pressure into a tank or reservoir to a predetermined level therein that will still operate in the event of one of its two diaphragms or its two pilot valves becoming inoperative, comprises, Fig. 1, two diaphragms 28, 30 clamped peripherally between housing parts 26, 27, 29 and attached centrally to a bolt 35 which carries a valve member 31 that controls the inlet 21 and is biased by a compression spring 41 to the closed position. Pressure chambers 45, 46 formed between the diaphragms and the upper diaphragm and the casing respectively are each in communication with the inlet 21 via restricted passages 44, 43 in the bolt 35 and the outlets ducts 51, 55 from the pressure chambers are controlled by float-actuated pilot valves 11 and 12 pivoted in a casing 56 attached to the upper side of the tank. Fuel is delivered under pressure to the inlet 21 to open to valve member 31 against the spring 41 to fill the tank and when the fuel reaches a predetermined level the pilot valves 11, 12 close and pressure builds up in chambers 45, 46 resulting in a nett downward pressure on diaphragm 28 to close the main valve. In the event of either of the diaphragms being ruptured, Figs. 3, 4 (not shown), the pressure acting on the unruptured diaphragm after the closure of the pilot valves is effective in closing the main valve. Should the float of the pilot valve 11 become logged and fail to operate, the main valve will still operate as if diaphragm 28 had ruptured, also, if the float of the pilot valve 12 becomes logged and fails to operate, Fig. 5 (not shown), the pressure in chamber 45 will cause the portion of diaphragm 30 which is not supported by a support plate 38 to seat on the housing part 29 and reduce the upward force on the valve member so that the valve can close in the normal way. In a modification, the pilot valve 11 may be omitted without interfering with the protection against diaphragm failure and in this case the passage 44 may or may not be omitted. In a further modification, the pilot valves may be of the pressure-sensitive electrically operated type.

Filed: 1936-07-15
Abstract: 460,499. Winding yarns &c. HEINITZ, W. July 15, 1936, No. 19681. [Class 120 (ii)] In a quick-traverse winding frame for yarns and threads in which the winding spindle is driven by friction gearing controlled from the thread guide, the centrifugal force exerted by the driving disc is.prevented from influencing the thread guide by a ball which is mounted between the jaws of a detent. As shown, the ball 56 is mounted between an arcuate grooved member 54 fixed to the machine frame and forming one jaw of the detent and a surface 55 forming the other jaw of the detent on a member 49 carried by a rock-shaft 48 and connected by pivoted links 51, 54 with an extension 43 on one member 38 of the swinging thread guide frame 36 ; the shaft 48 also carries a lever 59 controlling the movement of the friction driving disc 8 along the shaft 9 and face of the disc 7 on the winding spindle 4. As the frame 36 moves from the winding spindle 4 with the growth of the cheese 6, the extension 43 moves the link 51 and causes an arm 58 thereon to urge the ball 56 out of its locking position between the members 54, 55 against the return of a spring 57 and allows the controlling member 59 and consequently the driving disc 8 to move ; the disc moves outwardly over the disc 7 to reduce the speed of the winding spindle, but excessive movement due to centrifugal action is prevented by the movement of the member 49 which urges the ball 56 into the locking position again. The spindle disc 7 is forced against the driving disc 8 by a spring 12 and is moved away from the disc 8 when it is desired to stop the spindle by jaws 14 on a sliding rod 13 which is moved by a spring 20 when a catch 22 is disengaged from a pivoted latch, 25 ; the catch 22 is carried bv an arm pivoted to the rod 13 and actuated by a hand lever 16. The thread guide frame 36 is held against the cheese by counterweights 41, 42, the weight 42 being pivoted to the weight 41 and connected to an adjustable link so that it is rocked as the diameter of the cheese increases to balance the weight of the thread guide frame and its associated parts.
