Abstract: An ink pump (40) for a high speed mailing machine is disclosed. The ink pump 40 pumps ink from an ink reservoir 41 to an ink pad of an ink pad device 36. The ink pump 40 comprises a deformable chamber and valves (232, 234) which cooperate to pump ink upon compression of the chamber and release of the compression. The pump (40) comprises an input and an output, and the valves comprises a one way valve 232, e.g. a duck bill valve, disposed at the pump input which closes upon compression of the chamber and opens upon release of the compression, and a one way valve 234, e.g. a duck bill valve, disposed at the pump output which opens upon compression of the chamber and closes upon release of the compression. Duck bill valves (232, 234) enable the pump (40) to be disposed in any attitude including horizontal. These valves (232, 234) may be disposed entirely within the deformable chamber, which may comprise a sleeve 230 of elastic material.

Abstract: A process for rehabilitation of internally reinforced concrete which comprises the temporary application of an adherent coating of an electrolytic material (12) to surface areas of the concrete. Distributed electrode (13) means, preferably a wire grid, is embedded in the adherent coating. Voltage sufficient to develop a current of about 1-5 amps/m² is applied between the reinforcement and the distributed electrode, to cause migration of chloride ions from the concrete into the electrolytic coating. A highly preferred material for the adherent electrolytic layer is cellulosic pulp, premixed with water or other solution (such as calcium hydroxide) in a nozzle and sprayed onto the surface of the area being treated. Desirably, the distributed electrode is formed of a ferrous material reactive with chlorine, to minimize the release of free chlorine gas into the ambient. Particularly for tensioned reinforcement, the process monitors polarization of the tensioned steel to prevent hydrogen embrittlement.

Filed: 1990-08-04
Abstract: To determine a predicted image taking into consideration an image movement, an object mask is processed which describes position and location of the moving image component for each image. After the image has been split into blocks, the motion vectors are determined block by block for the image coming before it in time. Using these motion vectors, a prediction of the current object mask is generated from the object mask coming before it in time. Using this current object mask, the predicted image is generated separated by object, background becoming free and other background, which prevents the background from also being displaced as occurs in conventional coders. Finally, the predicted current object mask is improved on the basis of the information contained in the residual error image transmitted.

Abstract: A device having a number of general registers (28,48) each allocated an input/output port (12,14) and a number of internal "buried" state registers (76). A user-controlled signal (84) permits observation of the contents of the buried state registers (76) at an input/output port (14) although these registers are not allocated an input/output port. Each register is connected to a logic circuit internal to the device by a dedicated feedback path (42,64,80) sothat all registers can be used to specify states in a state machine sequencer. A fuse-programmable XOR gate (38,70) permits a user to control generation of signals at the ports by permitting enabling and disabling of an inverting output buffer (34,60). Asynchronous reset and synchronous preset of the registers is provided (29b;29c). In addition to the dedicated feedback paths (42) programmable feedback paths (64) are provided. An output inverter can selectably be enabled from internal signals or from an external pin. The input/output circuit can be deployed in banks, each bank selectably receiving the same or a different clock. The registers can be preloaded via an internally-generated signal or from the external pins. In an alternative embodiment, a programmable AND array and a pair of programmable OR arrays, each serving one of the banks, provides a flexible programmable logic array device with observable buried states.

Abstract: In multimeters having a plurality of input connections there is a danger of the measuring conductors being incorrectly connected in such a manner that the setting of the measurement range switch does not correspond to the input connections to which contact is made. In order to avoid damage which may be caused by making an incorrect contact to the input connections, an electrically and/or mechanically acting disabling device is coupled to the measurement range switch for permitting a disabling of particular input connections. The disabling is carried out in such a manner that contact can always only be made to that input connection for receiving a test signal through the measuring conductors, to which a measurable variable is assigned that corresponds to the measurable variable set with the measurement range switch.

Abstract: The device is organised in memory cell array portions (10 to 13), each having respective data transfer buses (DB0 to DB3, /DB0 to /DB3) and sense amplifiers (270 to 273, 280 to 283; 390 to 393, 400 to 403) for sensing data of a selected memory cell of the memory cell array portions (10 to 13), each sense amplifier being connected to corresponding output gates (250 to 253). At least two of the sense amplifiers (270 to 273, 280 to 283; 390 to 393, 400 to 403) are connected to each of the memory cell array portions (10 to 13) through the data buses (DB0 to DB3, /DB0 to /DB3), respectively. The selection of the sense amplifiers (270 to 273, 280 to 283; 390 to 393, 400 to 403) is controlled to be activated or deactivated by control signals (R, Q), to thereby change the output organization. Therefore, a data transmission delay can be eliminated, and a high speed operation can be consequently achieved.
