Title: Improvements relating to underground cryogenic storage reservoirs, and their operation
IPC: F17C3/00
Filed: 1978-10-24
Abstract: An underground storage reservoir for LNG or other fluids at cryogenic temperatures comprises an underground cavern (10), usually insulated, an inner circulation system surrounding the cavern and comprising a plurality of passages (18 to 22) and an outer circulation system comprising a plurality of ducts (11 to 15). A heat exchange gas is circulated through the inner circulation system so that the temperature of the cavern wall and the ground immediately surrounding the wall is maintained within a predetermined temperature range higher than the temperature of the stored fluid and the critical temperature at which the ground cracks. A heat exchange gas is also circulated through the outer circulation system so that a frozen zone is established and maintained in the ground encircling the inner circulation system. The invention then involves adjusting the pressures in the inner and outer circulation systems so that gas is caused to diffuse outwards through the ground towards the outer circulation system in counterflow to water vapour migrating inwards, so that the movement of water vapour is halted or reversed. <IMAGE>

Title: A barrier opening device
IPC: E05F15/08
Filed: 1979-05-31
Abstract: A remotely controlled piston (12) and cylinder (10) is used to open a garage door. The cylinder (10) is fixed to a foundation and the piston rod connected by pulleys to the door. The pressure in a direct mains water supply drives the piston (12) into the cylinder (10) when it is in the closed position to open the door. The supply of water to the cylinder is controlled by a solenoid valve (54) in the supply conduit (32), the valve being opened on receipt of an opening signal from a transmitter and closed when the piston is in the open position by a reed limit switch (40) operated by a magnet (38 not shown) carried on the piston (12). On receipt of a closing signal, a solenoid valve (58) in a bleed conduit (60) opens and the water is led to waste, travel of the piston (12) to closure being again controlled by a second reed switch (41) closing the solenoid valve (58) in the bleed conduit (60). <IMAGE>

Title: Security alarm systems
IPC: G08B29/12
Filed: 1979-06-07
Abstract: For fault monitoring in a multi- line security alarm system, a circuit (46 and 52) detects high frequency bursts of pulses received by the transponder (36) in an out-station (or transmitted by the transponder) to light an indicator lamp (48). The test circuit may be in a probe or mounted permanently in the out- station with switch means (38) for supplying either the output signals from the receiver or the signals from the transponder output to the circuit. Logic circuit means (64, Fig. 5) may generate a pulse corresponding to the period between the end of a received call signal and the beginning of a transmitted reply signal to flash a lamp (68), and second circuit means inhibit a second lamp (86) when the transponder is producing output signals. <IMAGE>
Patent GB-2023607-A (GB)
Title: Specific Binding Assay Method With a Prosthetic Group as a Label Component
Inventor: HORNBY WILLIAM E
IPC: G01N33/542
Filed: 1979-06-21
Abstract: A specific binding assay for determining a ligand in a liquid medium employing an organic prosthetic group residue, such as a residue of flavin adenine dinucleotide, flavin mononucleotide, or heme, as a label component in the labeled conjugate, Preferably, the label component is the prosthetic group residue alone or is a holoenzyme residue comprising such prosthetic group residue combined with an apoenzyme in the form of a holoenzyme complex. In the former case, the label component preferably is monitored in the assay by adding an apoenzyme after the binding reaction has been initiated and measuring the resultant holoenzyme activity. In the latter case, the label component is monitored simply by measuring holoenzyme activity. The assay method may follow conventional homogeneous and heterogeneous schemes. Preferred apoenzymes for use in the assay are apoglucose oxidase and apoperoxidase. The assay offers the advantages of colorimetric read-out and of being readily adaptable to automated techniques. Also disclosed are prosthetic group- labeled and enzyme-labeled conjugates for use in the assay, as well as a method for preparing the latter conjugates.

Title: Apparatus for Producing Axial Movement
IPC: F16H25/24
Filed: 1980-01-04
Abstract: In apparatus which includes a rotatable member 1 and a relatively fixed or non rotatable member, the two members are coupled by a thread type arrangement whereby one of the two members is moved linearly relative to the other when the rotatable member is rotated. The rotatable member 1 includes a cylinder 3 and a plurality of rollers 5 attached to the outer periphery of the cylinder. The rollers are arranged in a helical line and extend radially outwardly from the cylinder. The fixed member includes a semicylindrical wall having a plurality of slots or channels formed in it, the channels also following a helical line that is similar to the line followed by the rollers. When the rotatable member is turned on its axis, the rollers move through the channels and cause relative linear movement of the two members. <IMAGE>

Patent GB-2041023-A (GB)
Title: Yarn Winding Machine
IPC: B65H54/28
Filed: 1980-01-22
Abstract: A yarn winding machine includes a driven spindle 14 for a package 12 and traversing mechanism for yarn 6 which includes a pair of contra- rotating, slightly eccentric discs 2,2'. Each disc is formed with a pair of slot- like yarn-driving guides and the yarn is transferred from a guide on one disc to a guide on the other disc at one end of the traverse and back again to the first disc at the other end of the traverse. In addition, the yarn path between the discs 2, 2' and an upstream yarn positioning guide is lengthened by the inclusion of a member 10 constituting a yarn guiding surface. This member is so shaped and arranged that the path length travelled by the yarn as it approaches each end of the traverse does not increase further during the last part of the movement to the transfer point, whereby the tension in the yarn has no component tending to move the yarn inwardly along the general line of traverse prior to transfer, thus facilitating smooth transfer of the yarn from one disc to the other. <IMAGE>

Title: Filling accumulator batteries
IPC: H01M50/609
Filed: 1980-04-15
Abstract: Apparatus 1, for feeding distilled water into individual cells of an accumulator battery, comprises a casing connected to an inward flow conduit by a connecting pipe connected in turn to a borehole 142 opening into an annular channel 154 in turn connected to a valve chamber 17 through a duct 155. Distilled water is fed under high pressure through the inward flow conduit into the borehole 142, which reduces the pressure, and then into valve chamber 17. It passes through a valve opening 153 into a syphon 112. Pressure caused by a difference D in level P of electrolyte E outside, and level Q of distilled water inside an attachment 111 causes housing 13 to move upward inside the casing 2 until a valve washer 16 closes the valve opening 153. <IMAGE>
