Title: Demineralization of water by reverse osmosis
IPC: C02F1/00
Filed: 1980-03-27
Abstract: A process for the demineralization or partial demineralization of water containing salt, for example sea water, in which untreated water containing salt is compressed and fed to reverse osmosis apparatus (u/o) which separates the water into a concentrate stream (B) rich in salt and a permeate stream (P) poor in salt. The concentrate is fed through an expansion turbine (T) to recover pressure energy. When treating water with a salt content of more than 13 g/kg, the initial pressure (P11) of the untreated water is above 80 bar and the proportion of permeate to untreated water is above 0.4. When treating water with a salt content of less than 13 g/kg the initial pressure (P11) of the untreated water is above 60 bar and the proportion of permeate to untreated water is above 0.7. <IMAGE>

Title: Signalling system
IPC: H04Q3/545
Filed: 1980-05-01
Abstract: A data processing system, for use in a stored-programme-controlled telephone exchange, consists of a number of controlling units (MEM, CPU) which in the case of a telephone exchange control the establishment of calls in a telephone switching network (TSN). The controlling units include an operating system (OS) the main part of which is a message handling system (MH) with which finite message machines (FMM1, FMM2) are associated. The messages interchanged between the various units of the system include messages each of which does not include the address of the destination unit, routing of these messages being controlled by routing tables each of which is associated with (or is included in) the originating unit. Each finite message machine in the system has a predetermined set of input messages and a predetermined set of output messages, and a sequence of at least one output message is sent only in response to the receipt of an appropriate sequence of at least one input message.   Two types of message are used: (a) system basic messages wherein the destination unit is not specified anywhere in the message, and (b) directed messages wherein the destination unit is specified in or by the data of the message. <IMAGE>

Title: Improvements in the cooling of wire rod
IPC: B21B43/00
Filed: 1980-07-08
Abstract: The first portion (3) of a cooling path for cooling hot-rolled wire rod or wire (2) slopes downwardly from a likewise inclined rolling finishing block (1) at an angle ??? of at least 3 DEG  so that the wire rod or wire is subject to little or no compressive stress due to the friction between the wire rod or wire and the tube through which the latter passes in order to be subjected to cooling liquid. The wire rod or wire can be placed under tension if the angle of slope alpha  is sufficiently large and, in an extreme case the first portion of the cooling path can descend vertically. A loop layer (4) deposits the wire rod or wire in overlapping loops (5) on conveying means (6) where the wire rod or wire is air- cooled. The avoidance or minimizing of compressive stresses in the first cooling section makes the wire rod or wire less prone to buckle. <IMAGE>

Title: Automatic control of fuel supply in i.c. engines
IPC: F02D41/02
Filed: 1980-10-13
Abstract: The fuel injectors 1, 2, 3, 4 of an i.c. engine are operated by pulses on line A and, in conditions of deceleration, when the throttle is closed, as signalled by a potential on line B, all or some of the injectors are rendered inoperative depending on the speed of the engine, signalled as a voltage on line C, and the values of reference voltages V2 V3. When rapid deceleration occurs the output of the differentiating circuit 30 causes comparator 24 to disable gates 18, 22 thus removing the ground from transistors 12, 14 which respond again to pulses on line A and thus prevent the engine stalling. <IMAGE>

Patent GB-2073158-A (GB)
Title: Outlet Connection
IPC: F16K31/18
Filed: 1981-01-26
Abstract: An outlet connection comprises two telescopically interconnected pieces of pipe 2 and 4. The connection can be used to connect a supply container to a receptacle to be filled. The weight of the supply container moves the pipe 2 into the pipe 4, against the action of a spring 16, opening a closure valve 13 and permitting fluid to flow through the connection. One or more floats 17 cause the valve 13 to act as a float valve so that flow is cut off when the level in the receptacle reaches a predetermined height. The supply container can be removed before it is emptied, and the spring 16 will cause the valve to close automatically. <IMAGE>

Title: Optical information record and a method of reversibly recording and erasing information thereon
IPC: G11B7/0055
Filed: 1981-05-13
Abstract: The record comprises an absorptive layer (22) with a capping layer (24) overlying it to inhibit irreversible recording in the absorptive layer, and possibly a reflective layer (18) and a transparent spacer layer (20). An information track in the absorptive layer (22) comprises a sequence of regions in the absorptive layer whose optical properties have been reversibly changed for instance by a change in their crystallinity, thereby changing the reflectivity of the information record in these regions. Information may be recorded by exposing the information recording medium to a modulated light beam so that its optical properties in exposed regions of the absorptive layer (22) are reversibly switched to a second state. Erasure is effected by exposing the recording medium to a light beam so that the optical properties of the switched regions are reversibly returned to about their original values, permitting further recording. <IMAGE>

Title: Expansion of tobacco
Inventor: STEINBERG IRA H
IPC: A24B3/10
Filed: 1983-06-10
Abstract: Tobacco is expanded by cooling the same to a temperature of about 30 DEG  F. or less and subjecting such cooled tobacco to a subatmospheric pressure in a vessel. CO2 gas is then introduced into the vessel and contacts the cooled tobacco to impregnate the tobacco with CO2 gas as pressure in the vessel is brought to substantially atmospheric pressure. Subsequently, the cooled CO2 impregnated tobacco is subjected to conditions whereby the CO2 in the tobacco is removed and the tobacco is expanded. Typically, the CO2 impregnated tobacco is introduced into an expansion tower wherein it is heated to increase the volume of the CO2 and to expand the tobacco in size.
