Title: A data processing system incorporating an automatic reset arrangement.
IPC: G06F1/00
Filed: 1984-08-10
Abstract: The data processing system includes a processor and at least one releasably attached program cartridge. The processor includes a reset circuit (28,27,41,42,43,44,45) and physical and electrical devices (3,17-28) for the releasable attachment to it of one or more program cartridges. The or each cartridge has two adjacent edge connectors replaced by a single connector (14) with a projection (29) which passes into the area in which the adjacent connector would normally be placed. - When the cartridge is inserted or removed from the connector socket (3) in the microcomputer, the projection transiently shorts a pair of associated socket contacts (27, 28).

Title: Method and apparatus for immunoassays.
IPC: C12Q1/00
Filed: 1985-05-11
Abstract: An apparatus and process for conducting ligand receptor assays. The apparatus comprises a first member which is a membrane or a filter (20) to which is bound a receptor for the ligand or which is capable of extracting cells carrying the ligand from a fluid sample. The apparatus further comprises a second member which is composed of absorbent material (22) which acts when in contact with the first member to induce flow through the first member (20) when a fluid sample is added to it. The apparatus is used to conduct assays by applying a sample to the upper surface of the first member (20) to bind ligand in the sample by means of receptor fixed to the first member or, in certain cases, by extracting cellular material which has ligand associated with it. Addition of the sample is typically followed by addition of labeled antibody against the antigen being assayed followed by a washing step to remove unbound labeled receptor. The presence of labeled antibody on the first member after washing is indicative of the presence of the antigen in the sample being assayed. In a preferred embodiment of the invention, the ligand is an antigen and the receptor is an antibody.

Patent IE-902122-A1 (IE)
Title: "Improved micropump"
Inventor: LINTEL HARALD T G VAN
IPC: F04B43/00
Filed: 1990-06-13
