Title: Viscometer
IPC: G01N11/14
Filed: 1980-03-27
Abstract: A viscometer comprises a bob (3) which is positioned in the liquid whose viscosity is to be measured and is rotated at constant speed by a motor (1) and drive assembly (2, 26).

Title: A switching arrangement for the digital remote transmission of signals
IPC: H04L25/20
Filed: 1981-03-04
Abstract: A switching arrangement is described by which a digital electrical signal is produced in response to a change in magnetic field occurring at a location (3), and is conveyed to a remotely- situated indication point (4) by way of an electrical conduction loop (1), in which a constant direct voltage (6) or a constant direct current is connected. The magnetic field sensor is a bistable magnetic element (8) which alters its direction of magnetisation abruptly under the influence of the change in magnetic field e.g. due to movement of a magnet (10). The abrupt change in magnetic field thus produced induces an electrical voltage pulse in an electrical winding (7) connected in the base circuit of a transistor (5), the collector and emitter of which is connected in the conduction loop (1) leading to the indication point (4). A pulse occurring in the winding (7) makes the transistor (5) conductive, whereby the latter transmits a pulse signal via the conduction loop to the indication point (4). <IMAGE>

Patent GB-2103848-A (GB)
Title: PCM system
Inventor: WADDELL MICHAEL ROBERT RICHARD
IPC: G06F7/49
Filed: 1981-08-20
Abstract: Summating of PCM words, e.g. for tone injection into an existing conversation is effected without conversion from the usual CCITT A Law format to linear representation. The method relies on the fact that for satisfactory results, only the four bits for the step value within a segment need to be added, with adjustment to the segment code if needed. The embodiment uses a set of PROM's, of which PROM 1 indicates whether the device is to add or subtract (done by two's complementing the diminuend and adding) and indicates the maximum segment. Each of the PROM's 2 does the shifting needed so that binary bits of corresponding numerical significance are aligned to allow correct addition, plus the complementing of one or other value, as called for. The summator adds the two four bit codes, and PR0M 3 and PROM 4 attach the sign and segment codes to the step-within-segment codes, with such shifting as needed. <IMAGE>
