Title: A syphon unit for flushing cisterns
IPC: E03D1/08
Filed: 1979-02-09
Abstract: A discharge siphon unit for a w.c. cistern can be preset to give either single flush or dual flush action by rotatably positioning a cap 17 to close off (single flush) or open (dual flush) a siphon-breaking air vent cooperating with a valve member 21 on the flushing piston 7. When set for dual flush a full flush is obtained by holding piston 7 raised so that member 21 blocks the air vent; if the piston is not held raised then flushing ceases as soon as the water level falls to B. The piston 7 supports a flexible diaphragm 10 and is loaded by a gravity-assisting spring 11. <IMAGE>

Title: Sulphonation of alkylated aromatic hydrocarbons
IPC: C07C309/31
Filed: 1979-05-24
Abstract: In a process for the production of sulphonated alkyl aromatic hydrocarbons, wherein alkylated aromatic hydrocarbons are sulphonated with a gaseous sulphonating agent comprising SO3, an anhydrous low molecular weight carboxylic acid is added to the hydrocarbon before sulphonation. Such an addition can improve the colour and can lower the H2SO4 content of the sulphonic acid reaction product. Advantageously, the hydrocarbon is sulphonated in an atomized condition to provide a reaction mixture which is quenched by, and agglomerated in, cooled, recycled reaction product.

Title: Improvements in or Relating to Plate Heat Exchangers
IPC: C23F13/02
Filed: 1979-06-13
Abstract: The invention deals with the problem of fouling by marine growths in plate heat exchangers using seawater, or brackish water, by generating chlorine electrolytically in situ and allowing the chlorine to circulate through the flow spaces of the heat exchanger in which the seawater or brackish water circulates. It is preferred that the chlorine should be generated at an anode formed by the plates themselves, while the cathode is an elongated electrode supported in and extending along an inlet duct for the sea-water or brackish water formed by aligned holes in the plates.

Title: Liquid crystal display device
IPC: G02F1/139
Filed: 1979-07-30
Abstract: A liquid crystal display device comprises two electro-optic 90 DEG twist cells in tandem, between polarisers and with no interposed light affecting elements, the alignments in the upper cell U and lower cell L being one of the combinations 20-23, where the solid and dashed arrows respectively relate to the upper and lower surfaces of the liquid crystal layers, whereby the display exhibits maximum contrast when viewed from between the 4.30 and 7.30 directions. Both layers exhibit the same degree of contrast in the 6 o'clock direction, have the same twist sense and may be of the same material. When both layers are in the twisted state the polariser through which light is transmitted to cell U is arranged to provide a linear polarisation always at 90 DEG  to the long liquid crystal axis, to reduce light absorption. The two layers may be arranged to display different types of information. <IMAGE>
Patent GB-2056093-A (GB)
Title: Monitoring a number of voltage conditions
IPC: G01R19/165
Filed: 1979-08-07
Abstract: In e.g. a telecommunication exchange system it is frequently necessary to be able to test voltage conditions e.g. on any one of a number of subscriber's lines. To do this, the lines are connected via resistive networks to the inputs of a multiplexer, which may consist of two or more multiplexer units (1, 2, 3), which units are controlled by a selection circuit (17) to select one of the multiplexers. Address selection means then selects one of the lines served by the chosen multiplexer. Each of the resistive networks is a potential divider which, in effect, converts the line voltage from a high range (e.g. -64 + 64 volts) to a lower voltage range (0 to 5 volts) more suitable for an input to an integrated circuit. The output from the multiplexer, which is a voltage proportional to the analogue voltage on the line to be tested, is applied to an analog to digital converter (1) which produces as an output a parallel binary code which corresponds to the analogue voltage. This arrangement of selecting one line for monitoring can be replaced by a continuous scan process. <IMAGE>

Title: Detecting vehicles
Inventor: CUQ BERNARD
IPC: G08G1/04
Filed: 1979-10-19
Abstract: Apparatus for the detection of vehicles by infra-red detection of their exhaust comprises an infra-red detector (1) and processing means 6-18 for distinguishing a pulse (fig. 6a) in the detector output due to the presence of a vehicle from the varying background level. In one embodiment a low pass filter 8 provides a signal representing the background variations. This background signal is then boosted in level (10) and combined with a delayed version (6) of the detector output to provide a reference signal 13. The detector output will be greater than the reference only when a pulse occurs, the reference being such that the higher the background level on which the pulse is superimposed, the lower the pulse amplitude needs to be for it to exceed the reference. Another embodiment (fig. 8, not shown) multiplies the detector output by a function of the background level and then compares with a fixed threshold. <IMAGE>
