Title: Liquid-carrying tubes
Inventor: BARTON RICHARD
IPC: B60K15/04
Filed: 1988-08-08
Abstract: A tube (3a) for the passage of liquid such as derv into a tank comprises a grill (5) positioned within the tube. The grill extends throughout the cross-section of the tube, and has a number of apertures (9). The sizes of the apertures are such that when liquids are fed through the tube at working pressures they are emitted from the grill in the form of jets (11). This reduces the tendency of the liquid to foam or atomise as it passes through thr grill, and the grill prevents the passage of foreign bodies through the tube. The radial dimension of an aperture may be 4mm. <IMAGE>

Title: Communication circuit fault detector
Inventor: YAMADA YOSHIKO
IPC: H04L69/40
Filed: 1990-05-30
Abstract: A communication circuit fault detector tests a communication circuit (11) by using a sequence generator (15) to generate a test signal (B), a memory circuit (17) to temporarily store the test signal, and a multiplexer (19) to multiplex the test signal and an input data signal (A) into the communication circuit. A timing generator (13) drives the communication circuit at a rate higher than the normal communication rate, thus enabling the data signal and test signal to be sent through the communication circuit simultaneously. A demultiplexer (21) demultiplexes the output signal (F) from the communication circuit into an output data signal (H) and a returned test signal (I). A comparator (23) compares the returned test signal with the test signal stored in the memory circuit and generates a result signal indicating whether they match. <IMAGE>
