Patent SE-8501603-L (SE)
Inventor: ROBINTON M A
IPC: G01R21/133
Filed: 1985-04-01
Abstract: The metering system and method provides an electronic power meter for simultaneously producing digital pulse trains proportional to power and to VARS or Q. In the preferred embodiment, the metering system employs delta-minus-sigma modulation of the voltage signal which produces a modulated output signal used for gating the analog current signal, multiplying voltage and current. The product of voltage and current is then supplied to another delta-minus-sigma modulator (90), which serves as a convertor outputting a pulse train. The converter (90) produces separate pulse trains for each polarity of the power being measured. VARS or Q readings are produced by delaying the output of the modulator (30) by a selected amount to produce the necessary voltage lag, after which the delayed modulated signal is supplied to another multiplying gate. A second converter (90) is used to output VARS and Q. A metering method is also disclosed, as well as an offset compensation system (70, C1) for use with metering systems.

Abstract: Mechanism for keeping clean the narrow gaps between the impeller of a pump, especially a sewage pump, and an object placed against the impeller in the direction of the rotational axis of the impeller, for example a pump casing. Keeping the gaps clean of solids contained in the wastewater has been found to be a very difficult problem. According to the invention, this problem has been solved by providing at least the side of the impeller facing the pump casing and the corresponding side of the pump casing with projections arranged eccentrically with respect to the axis of rotation of the impeller in such a way, that the mutually overlapping proportions of said projections alternately increase and decrease during the rotation of the impeller.

Abstract: A pneumatic or hydraulic cylinder with built-in velocity control has a connection port (1) for intake and removal of working medium to and from the respective cylinder chamber (3). A first inner part of said connection port facing towards the cylinder chamber is provided with a non-return valve means (2, 4, 5, 14), which is constructed such that on one hand it permits working medium inflow with small flow losses to the cylinder chamber from an outer part of the connection port situated outside said non-return valve means, and, on the other hand, it blocks outflow of the working medium from the cylinder chamber to said outer part of the connection port. A second inner part of said connection port, similarly facing towards the cylinder chamber, is provided with an adjustable constriction valve means (6, 6a), which is constructed to enable a variable degree of working medium outflow from the cylinder chamber to said outer part of the connection port depending on the desired working velocity of the cylinder.

Abstract: In a packet switch, which is intended for packets of constant length, and which, between switch ports, is divided into a number of nodes (12) and transmission links (14), where the nodes carry out space selection and the transmission links offer point-to-point transmission between the nodes, link grouping is carded out. More particularly, from multiple parallel physical links coming in the switch, link groups are produced, each in the form of a logical link with a bandwidth that is the sum of the bandwidths of the physical links included in the link group, said logical link being restored to outgoing parallel physical links from the switch. One or more link protocols (G1,G2) are used according to which a label in the packet's header is made to describe a route that holds together the grouped links through the entire switch, such that bits in the label describing the route over a certain transmission link are the same for packets belonging to the same link group.

Abstract: A cylinder head assembly for an internal combustion engine. The cylinder head assembly has a deck surface for engaging an opposed deck surface on an engine block. A combustion chamber is recessed in the cylinder head assembly for each cylinder, and the combustion chambers each have first and second wedge portions. A first valve port penetrates the first wedge portion, and a valve seat is provided in the first valve port. The first valve seat is disposed at a first angle relative to the deck surface. A second valve port penetrates the second wedge portion, and a valve seat is provided in the second valve port. Thesecond valve seat is disposed at a second angle relative to the mounting surface. The second angle is less than the first angle. Each valve seat has a valve element for controlling the ingress and egress of gas flowing to and from the chamber. The wedge portions permit a more erect valve orientation for the intake valve such that less scavenging of the fresh fuel/air charge will occur. The wedge portions also permit the exhaust valve and intake valve to moved to more advantageous locations relative to the combustion chamber. The relocation of the valves allows a more efficient placement of the spark plug, resulting in more even loading of the piston during the power stroke. The inlet passage which directs the fuel/air mixture to the combustion chamber has an independently unique configuration that improves atomization of the fuel/air mixture to achieve improved fuel economy and/or increased brake horsepower output.

Abstract: This application describes a way of providing emergency cooling of a room containing heat-emitting equipment. Emergency cooling is required in the event of a power failure in the room containing heat-emitting equipment even during a break in the power supply, when battery operation often comes into force. Then problems occur in that the battery capacity does not permit operation of the cooling equipment. This invention shows a way of obtaining emergency cooling of material with a high thermal capacity, thanks to phase changes. In this way the heat-emitting equipment can work without interruption in the event of a power failure without the equipment's maximum working temperature being reached, which would be the case without emergency cooling.
