Patent GB-2082817-A (GB)
Title: A monitoring circuit
IPC: G08B29/12
Filed: 1980-08-18
Abstract: A monitoring circuit particularly adapted for monitoring a liquid level such as the level in a bilge of a vessel has a float-switch (11) connected between a power supply (12) and a pair of parallel connected visual indicators (19, 20) which are arranged to flash when energised. In parallel with the visual indicators (19, 20) is an audible indicator (21) connected in circuit with the float-switch (11) via the normally closed contacts 15b, c of a latching relay the coil of which can be energised via a first set of contacts 14a, c of a push button switch (14) connected between the coil and the float-switch (11). A second set of contacts 14b, d of the push-button switch (14) by-passes the float-switch (11) and connects the power supply (12) directly with the visual indicators (19, 20) to provide a test facility. Testing does not energise the relay because the float-switch (11) is normally open. When the float-switch (11) is closed, depression of the push- button switch (14) causes energisation of the relay coil to silence the audible indicator (21).   <IMAGE>

Title: Improved echo recognition system
IPC: G01S7/527
Filed: 1980-10-03
Abstract: An echo type rangefinding a system, preferably using ultrasonic energy bursts, includes a transducer for transmitting and receiving the energy burst and signal processing means for identifying a true echo of the energy burst (54) from a selected target. The signal processing means discriminates against spurious signals and electronic noise, some of which may be generated by the rangefinding system itself, by rejecting signals that do not persist for at least a predetermined period. Preferably, the system recognizes the leading edge of a true echo signal by sampling the integrated signal (156) at sampling intervals (158) which are small compared with the said predetermined period (for example 0.6 milliseconds). If the samples integrated signal voltage (Vc) steadily increases at at least a given minimum rate for at least the predetermined period then the signal processing means provides an "object detect" signal. The accuracy of the rangefinding system is improved firstly because of the improved signal discrimination, and secondly because the object detect signal is always produced at the same time after the beginning of the true echo signal. <IMAGE>

Title: Coffee maker
IPC: A47J31/057
Filed: 1980-10-31
Abstract: An automatic electric coffee maker has a tubular heating chamber (8) carrying an electrical resistance wire winding (9) for heating water flowing through the tube between a water reservoir (2) and discharge pipe (5). To promote an even boiling process throughout the length of the chamber (8), the winding (9) turns are arranged so as to dissipate more power at the inlet than at the outlet end of the chamber. To achieve this the spacing of the turns may vary or the diameter of the wire may vary. <IMAGE>

Title: Determining optical transmission of fluid samples
IPC: G01N21/59
Filed: 1981-03-02
Abstract: A system for determining optical transmission of fluid samples, in particular for determining the concentration of haemoglobin and other parameters in blood by colour reaction, uses a double light-ray technique in which one ray only is passed through the fluid and each ray impinges on one of two photosensitive elements 6, 7, the two resulting signals each being passed to one of two signal converters 8, 9, the outputs of which are sent to a signal processing, storage and control unit 10, 11 which inter alia converts the analogue signals to digital signals and forms a ratio of the two signals. The control unit also monitors the whole system and performs, for example, error estimation, averaging of measurements and linearising; controls a pneumatic sampler 15 and displays results on a digital display unit 13. <IMAGE>

Patent GB-2084438-A (GB)
Title: Channel induction furnaces
IPC: H05B6/20
Filed: 1981-09-23
Abstract: A channel induction furnace, particularly for melting aluminium has a pair of U-shaped channels (11, 12) extending downwardly from a bath (10). Each channel has a radial width, measured outwardly from the axis of the core (13), which is several times the penetration depth in the molten metal of a current of the energising frequency and, below the level of the core, the channel section is tapered so that the channel is wider, in a direction parallel to the core axis, near the core and narrower away from the core. The channels are skewed about an axis of skewing normal to the axis of the core. The large radial width gives a non-uniform current distribution resulting in flow patterns across the channel. The tapering provides an unbalanced electromagnetic pressure between the base of the channel and the bath and generates a further flow pattern whilst the skewing produces unidirectional flow through the channel. The combined effect enables high power to be put into the inductor without causing any pinch effect resulting in breaking of the metal path along the channel. <IMAGE>

Title: Device for contactless gauging of surface roughness
Inventor: LEONHARDT KLAUS
IPC: G01B11/30
Filed: 1983-11-11
Abstract: The invention further develops the device known from the Federal German Republic Patent specification No. O/S 30 20 044. In addition to the vertical surface roughness parameter, the correlation length, which represents a horizontal surface roughness parameter, is also determined. This is achieved in that the mirror 9 is divided and has different degrees of reflection and in that the detector 15 is formed as a detector pair 15a, 15b. It is preferable for one mirror half to be reflective and for the other mirror half to be non-reflective. It may be advantageous in this respect for the reflective mirror half to be made of the same material as the surface to be tested. The effects of the constant light superimposed by the mirror 9a, 9b may also be produced by superimposing corresponding equal fluxes on the detector fluxes or by adding corresponding computer values to the evaluation computer. <IMAGE>
