Patent NO-168298-C (NO)
Inventor: O'NEILL BRIAN T
IPC: C07C69/63
Filed: 1988-08-05
Abstract: The present process produces the meso dialkyl 2,5-dihaloadipate from a mixture of the racemic dialkyl 2,5-dihaloadipate and meso 2,5-dihaloadipate. In the disclosed process, a 2,5-dihaloadipoyl halide is formed under conditions which result in the formation of an acidic compound. The 2,5-dihaloadipoyl halide is then esterified under conditions wherein the ester of the dihaloadipoyl halide is allowed to remain in contact with the acidic compound, thus allowing the racemic diester to epimerize in the presence of the acidic compound to the meso form and then the meso diester spontaneously crystallizes. In the last stage, the meso diester produced is removed.

Abstract: The invention provides an improved system for masking the free edge of a window gasket in preparation for re-painting or re-finishing a vehicle. The system includes a method of painting a vehicle which comprises introducing a flexible plastics strip beneath a window sealing gasket in the vicinity of a part of the vehicle to be painted, the plastics strips having a tapered profile in cross-section so that as the strip is pressed beneath the gasket, the latter is lifted and held in the raised position, masking the edge of the raised gasket and applying paint to the vehicle so that paint reaches the area normally covered by the edge of the gasket. Generally, the strip is a plasticised polymer in the form of a triangular cross-section having one side longer than the other two. An applicator is also described which comprises a handle and a pointed end for lifting the free edge of a window sealing gasket, the applicator having a recess or aperture adjacent to the pointed end, said recess or aperture being shaped to correspond approximately with the cross-section of the flexible, plastics strip. <IMAGE>

Title: Joining and connecting component for corrugated pipes
Inventor: SCHWARZ ERNST
IPC: F16L33/28
Filed: 1998-02-11
Granted: 2001-07-19
Abstract: The connecting component or the connecting fitting (1) comprises at least one locking element which can be shifted-in and shifted-out radially to the longitudinal axis (14) of the fitting (1). The locking element is, for example, connected as a wing (7) via a hinge (22) with the fitting (1) or forms an additional element. On the inside face (10) of the locking element (7) are disposed a multiplicity of locking splice-clips (12) which are resilient. When a pipe end is slid into the fitting (1) with the locking elements (7) closed, these locking splice-clips (12) can be deflected. When load is applied against the insertion direction they become clawed in the pipe jacket. This embodiment permits the shifting-in or dosing of the locking elements (7) in a preassembly step and yet ensures a secure connection. The release of the connection through the radial shifting-out of the locking elements (7) is possible at any time.

Title: Adaptive interframe prediction coded video communications system
Inventor: TANOI TOSHIYUKI
IPC: H04N7/32
Filed: 1990-05-11
Granted: 1995-07-11
Abstract: At the transmit end of a video communications system, a first motion vector is derived from successive frames during a frame transmit mode and a second motion vector is derived during or immediately following a frame discard mode. An interframe predicted error signal is generated which is representative of the difference between each input frame and a motion-compensated, previous frame during the frame transmit mode, the difference being zero during the frame discard mode. The predicted error signal and the vectors are transmitted to the receive end of the system. In a first embodiment, the second motion vector is derived at the transmit end from frames spaced apart by a discarded frame, and at the receive end, original frames are recovered from the predicted error signal as well as from the first and second motion vectors, and the second motion vector is down-scaled and evaluated whether it is valid or not. During frame discard mode, motion compensation is performed on the recovered frame using the down-scaled vector in response to a valid evaluation, but no compensation is performed if invalid evaluation is made. In a second embodiment, the second motion vector is derived at the transmit end from successive frames using a larger block size than that used in the first motion vector. At the receive end, the first motion vector as well as the error signal are used in recovering original frames. During the frame discard mode, the second vector is simply used for motion compensation.

Abstract: PERSONAL COMPUTER MEMORY BANK PARITY ERROR INDICATOR      ABSTRACT       A personal computer has two memory banks respectively connected to two parity check units operative to detect parity errors.  Upon doing so, each unit feeds a parity error  signal  to  a  separate  latch.   The  latches  are connected to a logic circuit which is in turn connected to an interrupt controller that initiates an interrupt when a parity error occurs.  One latch is further connected to a check bit of a register of an I/O port and the check bit is set by said one latch.  An interrupt handler reads the register  and provides messages  indicating which memory bank caused the parity error.

Title: Method and an arrangement for accurate digital determination of the time or phase position of a signal pulse train
Inventor: DENT PAUL WILKINSON
IPC: G01R25/00
Filed: 1990-03-28
Granted: 1998-07-07
Abstract: The invention relates to a method and an apparatus for accurate digital determination of the time or phase position of a signal pulse train in relation to a fixed time or frequency reference. The arrangement generates and produces directly on the output a digital word corresponding to the measuring value current at that time.            The pulse train is compared in a plurality of EXCLUSIVE-OR gates (OR0-OR3) with a number of reference clock signals (RCL0-RCL3) which are mutually displaced in time. There is produced on the output of each gate a signal (MS0-MS3) which is dependent on the input signals of the gates with respect to frequency and pulse ratio. The output signals from the gates are sent to a comparison circuit (CO) in which a MIN of MAX operation is carried out, the pulse ratio of the output signals (MSO-MS3) being compared and the output signal which lies nearest to a predetermined pulse-ratio value being  subjected to  analogue/digital  conversion  in  a converter (AD). The pulse train, in digital form, is thereafter code-converted in a code converter (CC) together with the three most significant bits taken from the pulse train prior to the AD-conversion process. The thus produced binary code can be corrected for systematic deviations resulting from frequency differences between the  frequency,  reference  frequency  and/or sampling frequency of the pulse train, by the addition/subtraction of a predetermined numeric sequence.
