Patent EP-0044450-A1 (EP)
Inventor: HART PETER ANTHONY
IPC: G06F7/575
Filed: 1981-07-02
Abstract: A digital adder circuit for binary-coded-decimal operation, comprising a set of multiplexers (11) which are conditioned with a pattern of input bits causing them to form an intermediate result (IR) equal to the sum of the two operands (AO - A3, B0-B3) plus a correction value of six. The intermediate result is adjusted by subtracting the correction value if the intermediate result is less than sixteen. The circuit is also operable in a pure binary mode, or can be made to perform various logical operations.

Abstract: In control slides (5) for concrete pumps, there is a problem of sealing the connection point (7) of the pivoting slide, for example at the plate (17) on the pump cylinders, or the connection point to the discharge pipe. Use is made of a ring (8) made of an elastic wear-resistant material which is under the internal pressure in the tubular channel (4) of the control slide (5) and which, since it is under prestress, can compensate changes in length occurring as a result of the wear or elastic deformation and which seals off the connection point. At the connection point (7) to the pump cylinders, use is additionally made of a wearing ring (16) which is pressed by the annular face (10) of the elastic ring (8) by a sliding face (19) onto the plate (17). The wearing ring (16) is mounted especially rotatably, thereby ensuring as uniform a wear as possible. The construction is also capable, as a result of a non-uniform deformation of the ring (8), of compensating changes in angle of the surface of the plate (17). <IMAGE>

Abstract: A television ghost signal cancellation system is provided which compensates for the phase of the ghost carrier signal. A video signal containing a ghost signal component is applied to a variable delay line (10), which delays the video signal by an amount of time equal to the difference in time between the appearance of the direct video signal and its corresponding ghost signal components. The delayed video signal is modulated (12) by a carrier signal and demodulated (16) by a phase-shifted (18) version of the carrier signal. The carrier signal is phase-shifted for the demodulator (16) by an amount which compensates for the phase difference between the picture carriers of the direct and ghost signals. The demodulated signal is inverted and its amplitude adjusted (20) to produce a pseudo-ghost signal which is substantially equal in amplitude but opposite in polarity to the ghost signal components. The pseudo-ghost signal is summed (50) with the original video signal to cancel the ghost signal components, thereby producing a deghosted video output signal. For further removal of residual ghost components in the output signal, the latter may be substituted as the input to the delay line for a recursive ghost cancellation operation.

Filed: 1982-08-12
Abstract: A hot melt foam adhesive system including a gear pump (10) wherein gas is mixed under pressure into the molten adhesive and is driven into solution with the adhesive. The adhesive gas solution is supplied at a relatively high pressure to a valved dispenser (26) or gun from whence it is dispensed onto a substrate. As the adhesive/gas solution emerges from the dispenser (26). the gas comes out of solution but remains entrapped in the adhesive, thereby forming an adhesive foam. The system includes a recycle flow line or hose (26a) for returning adhesive/gas solution from the dispenser (26) to the pump (10). Within this recycle flow line (26a) there is a pressure regulator (28) responsive to flow changes or viscosity changes of the adhesive/gas solution for maintaining a fixed back pressure in the system, thereby enabling the system to maintain a fixed and uniform flow rate from the dispenser (26) during all operating conditions of the dispenser (26).
