Title: Immunomodulating bryostatins
IPC: A61K38/00
Filed: 1989-01-10
Abstract: Low concentrations of the protein kinase C activators, bryostatins 1 and 2 synergized with rBSF-1 are useful in triggering differentiation (granule enzyme expression) and CTL development in naive, resting lymph node T-cells. Bryostatin greatly enhances efficiency of rIL-2 in triggering development of in vivo primed CTL during in vitro incubation, thereby providing evidence for the use of lower concentrations of rIL-2 for in vivo tumor rejection. Both bryostatin 1 and 2, trigger cytotoxicity of CTL clones against Ag-non-bearing target cells and inhibit CTL cytotoxicity against Ag-specific target cells. Bryostatin 1 and 2 synergize with Ca<+><+> ionophores in triggering the exocytosis of cytolytic granules from CTL at very low concentrations. Because of the lack of tumor promoting activity in the bryostatins, they are useful per se as immunomodulating drugs and as potentiators for rIL-2 in adoptive immunotherapy. <CHEM> y

Patent EP-0333687-A3 (EP)
IPC: F01P7/16
Filed: 1989-03-10
Abstract: A fail-safe thermostat for vehicular cooling systems 
is positioned in a junction (13) leading to an internal 
coolant passageway, a radiator passageway and a bypass 
passageway (19). An open housing seated in the junction 
supports a fixed central rod (44) extending into the wax 
filled interior of a movable cylindrical member (36) which 
controls the position of the interior segment (32) of a main 
valve (30). Expansion of the wax forces the cylindrical mem­
ber in a first direction against a compression spring (62). 
Fusible alloy is disposed in the coupling between the 
cylindrical member and the main valve, and melts at a 
specific temperature range in excess of the normal range. 
When this occurs the coupling is released in such a way 
that the spring forces the valve member to a second limit 
position opposite to the direction of expansion. A bypass 
closure member (64) at one end of the cylindrical member 
may be used to close the bypass passageway concurrently with 
increased temperature.

Title: Integrated circuit
IPC: G06K19/077
Filed: 1990-08-20
Abstract: In data carriers, particularly portable data carriers such as cheque cards, with integrated circuits, secret data are contained which must not be accessible from the outside. To prevent the integrated circuit in a data carrier from being mechanically exposed and then taken into operation and the signals on the conductor tracks being recorded by means of electron beams, the integrated circuit is covered with a metal layer which is applied in the same manner as the conductor tracks located underneath. Since this metal layer can be removed with a certain effort for the unauthorised investigation of the signals of the integrated circuit, this metal layer itself is preferably used as conductor track in that it is used for supplying various circuit sections with a reference potential. When the metal layer is removed, the integrated circuit and thus the data carrier is then no longer operable. <IMAGE>
