Title: Sludge dewatering device for e.g. sewage works, comprises mantle with perforated drainage tube, discharge valve for dewatered sludge, and press piston with cleaning nozzle
Inventor: LARSSON GUNNAR
IPC: C02F11/121
Filed: 1994-12-19
Abstract: Sludge is dewatered in a mantle (1) connected to a sludge tank (18) via a discharge valve (3), and to suction pipes (17, 21). A vertical perforated drainage tube (4) is centrally positioned inside the mantle and at its top end there is a beam (7) supporting a cylinder (8) with a piston rod (12) for operating a press cap (13) with an integral rinse water nozzle (15). A drainage pipe (24) removes water from the bottom of the mantle.  A dewatering device for sludge separated in an effluent purification plant comprises a mantle connected to a sludge tank, and between the bottom of the mantle and the tank there are suction pipes connected to pumps (16, 20). An inlet pipe (19) is connected to the conical inlet (2) of the mantle, this inlet being sealed at the bottom end by an adjustable discharge valve for the dewatered sludge, and communicating at the top end with a vertical perforated drainage tube centrally positioned inside the mantle. A beam mounted on the top end of the drainage tube is used to support a twin-action cylinder (8) with end positions (9-11) indicating piston rod positions. A press cap with a coating (14) is mounted at the end of the piston rod and includes an integral rinse water nozzle. A drainage pipe connected to the bottom part of the mantle is used to remove water used during rinsing and removed from the sludge.

Abstract: A device and a method for repairing of posts, in particular lamp posts, in which the lamp post (1) is cut off in the area of the damaged portion, which is then removed from the two parts (2, 7) of the post. Subsequently, the post parts (2, 7) are jointed by means of a jointing device comprising a jointing pipe (8) exhibiting a longitudinal slit (9), which pipe is made of an elastically deformable and resilient material. When being inserted into the post parts (2, 7), the jointing pipe is squeezed together, and the squeezing ceases after the insertion into the post parts in order for the jointing pipe to spring back elastically. Subsequently, the post parts are pushed together essentially end to end so as to form a stable joint between the two parts of the post.

Abstract: A particle and photon detector includes a body having a beam-incident surface (8) capable of releasing secondary electrons in numbers proportional to the number of particles incident on the surface, and a plurality of secondary electron multiplier channels (4) whose inlet openings are disposed in the beam-incident surface, therewith to amplify the number of secondary electrons. A center channel (2) extends from the beam-incident surface (8) through the detector body and enables a beam of particles or photons to pass through the body. The inlet openings of the secondary electron multipliers are conveniently disposed in the beam-incident surface in a ring around the center channel for receiving secondary electrons. The method applied in the detection of charged particles, such as ions and electrons, in a beam that contains charged and charge-free particles comprises the steps of subjecting the charged particles to the effect of an electric field so as to collect the charged particles in an outer tubular layer or beam which surrounds the residual beam of charge-free particles, such as to form two mutually, coaxial beams, wherein the outer tubular particle beam is captured by a plurality of secondary electron multipliers and wherein signals delivered by the electron multipliers are read-off.

Abstract: Internal combustion engine with fuel injection directly into the combustion chamber of the engine. The engine has inlet channels, the angle of incidence (valve angle) (alpha) of which is greater than 20° relative to the longitudinal axis of the cylinder chamber. The piston tops are made, firstly, with a surface portion inclined relative to a plane normal to the longitudinal axis of the cylinder chamber by an angle (gamma) equal to or less than the angle of incidence of the inlet channel, and, secondly, with a cavity connected to the inclined surface portion. By interaction between the angle of incidence of the inlet channels and the shape of the piston tops, there is generated in the combustion chambers a primary vortical movement in the inlet air about an axis perpendicular to the longitudinal axis of the cylinder chamber. The primary vortical movement generates a secondary vortical movement in the opposite direction in the piston cavity.

Abstract: The present invention relates to a method and a system for electronic commerce as well as a method for checking that a buyer has electronically registered a purchase before delivery of a purchased merchandise. A problem is to secure who the buyer (SBS) is without him or her having established a relationship in advance with the seller. The invention solves the problem by letting the seller offer his/her merchandise from an application (AP1-AP3) in an internal packet data network (CSN). The packet data network is connected to a GSM-network. The buyer (SBS) is provided with a mobile terminal (MS). A session with the application can be set up only from a mobile terminal, and the application then receives information about the identity of the terminal. With reference to this identity, the application sends an order back to the GSM-network. According to one embodiment, the order means that a payment order shall be registered in a payment node, which is controlled by the operator of the GSM-network, for later charging of the buyer. According to another embodiment, a given account number is checked.

Abstract: A stroke-action valve has on both sides of a narrow duct cross-section F preferably an annular groove connected with one of the connection chambers 2 a first and a second valve seat 6, 7. A closure element 8 co-operates with both valve seats 6, 7 and contains openings 18 which provide communication between zones 16, 17. The two zones 16, 17 ie next to the side of the two valve seats 6, 7 opposite to the narrow duct cross-section F are connected with the other connection chamber 3. In this way, even small lengths of stroke of the stroke-action valve permit the passage of relatively large flow quantities. Seal 13 has lips 14, 15 which co-operate with the seats and the seats may be offset for non-simultaneous closure. A further embodiment (figure 2) includes a leakage detection device in the form of a rotor (130) and an electro-optical pulse measuring component (133) and a device which measures the stroke of the valve closure element (108).

Abstract: FIELD: video equipment. SUBSTANCE: non-linear video signal processing provides gamma correction in order to improve displaying of picture details about black regions. In addition, image brightness is improved, when amplification depends on brightness and frequency characteristics. In each channel, respective color signal (R, G, B) is separated in stages (18) into low amplitude level constituent (V 2) and high amplitude level constituent (V 3). Said high amplitude level constituent (V3) is subjected to high-pass filtration (20). Said low amplitude level constituent V2 and part of high amplitude level constituent subjected to high-pass filtration V4 are mixed (R1, R2, R4) to initial linear video signal (V1 or R) in order to produce total signal (i5), which is applied to kinescope (12). Part of low amplitude level constituent V2 is bound to linear signal V1 using constant constituent R2. Part of high amplitude level constituent V2 is bound to linear signal V1 using variable constituent C2. EFFECT: improved image contrast using non-linear processing of video signal. 8 cl, 8 dwg

All the return pipes from the stop valves can lead to a collector, from which a common pipe leads back to the hopper. The valves can consist of deflectors movable between two positions. In one of these, all pipes to the shares are open, while in the other they are connected to the return pipe.
