Abstract: Retinoid-like compounds which act as agonists of the RXR retinoid receptor sites induce apoptosis of tumor cells in cell cultures, and are used as drugs to treat tumors in mammals including humans. Compounds which are specific agonists of RXR receptors and also compounds which are agonists of both RAR and RXR agonist (pan-agonists) induce apoptosis, although the RXR agonist compounds are preferred as drugs to avoid undesirable side effects associated with RAR agonist activity. The RXR agonists compounds are administered to mammals afflicted with tumors in pharmaceutical adapted for systemic topical or for intralesional administration. The range of concentration of the active ingredient RXR agonist compound in the pharmaceutical compositions is approximately between 0.001 and 5 percent by weight, and such that the composition delivers approximately 0.1 mg to 100 mg of the active ingredient per kg body weight of the patient, per day of treatment.

Title: Video signal processing
Inventor: THOMSON ROD
IPC: H04N7/26
Filed: 1995-03-03
Abstract: Cuts in a video signal are detected by first measuring a correlation parameter between successive images; this can be the sum of the maximum peak heights for each of 16 to 100 or more blocks in a block-based phase correlation procedure. An averaged value of this correlation parameter is maintained and the current measurement of the correlation parameter is compared with the averaged value. The presence of a cut is inferred where the current measurement drops beneath, say, 50 % of the average value.

Title: Process for the preparation of camphene by the rearrangement of .alpha.-pinene
Inventor: GSCHEIDMEIER MANFRED
IPC: C07C5/29
Filed: 1996-11-26
Abstract: A process for the preparation of camphene by the rearrangement of .alpha.-pinene in the presence of a titanium oxide hydrate catalyst under the action of heat, wherein .alpha.-pinene is refluxed until the content of .alpha.-pinene in the reaction mixture is still at least 3% by weight, and the rearrangement is then brought to completion in a secondary reaction at a temperature below 160°C. By carrying out the process in this way - refluxing to a relatively high residual content of .alpha.-pinene and performing a secondary reaction at a lower temperature - the formation of polymeric by-products is reduced. This process moreover increases the yield of camphene in that recycled tricyclene, concentrated in the distillation of the crude product, is partially rearranged to camphene or the formation of more tricyclene is reduced.

Title: Auto-calibrated digital-to-analog converter for a video display
Inventor: DINGWALL ANDREW GORDON FRANCIS
IPC: H03M1/10
Filed: 1996-11-28
Abstract: Each of N current summation type digital-to-analog (D/A) converters of a liquid crystal display driver generates an analog signal which provides pixel video information. In an error sampling interval of the D/A converter, the output signal of the D/A converter developed when the data to be converted is at full scale is compared in a comparator with a reference voltage. An error signal is sampled and is used for varying a control voltage developed in a capacitor. The control voltage controls the current sources of the D/A converter in a current mirror manner. The reference voltage is coupled in common to each of the comparators of the D/A converters. In this way, matching among the D/A converters and the accuracy of each are enhanced.
