Title: Leak testing piping
IPC: E21B47/10
Filed: 1980-08-08
Abstract: The invention relates to a method of testing leaks in piping and to apparatus for carrying out the method. The method comprises placing within the pipe (90) to be tested a tool (100) having spaced seals (102) arranged on opposite sides of the joint (92) to be tested and actuated so as to maintain constant pressure against the internal surface of the pipe (90). The seals do not need to be fluid-tight A search fluid such as 1 to 2% helium in air is then passed through the tool under pressure and into the annular space between the outside surface of the tool and the inside surface of the pipe between the two seals. The presence of any helium is detected by means of a mass spectrometer for example which has a probe extending into a gas trap (109) surrounding the joint to be tested. <IMAGE>

Patent GB-2086184-A (GB)
Title: Dialled digit receiver
IPC: H04Q3/42
Filed: 1980-09-30
Abstract: In a processor-controlled telephone exchange, each of a number of blocks of, for instance 32, lines is served by an interface which includes a dialled digit receiver (1) formed by an uncommitted logic array. There is also a microprocessor (4) and a RAM (3) in which there are two data bytes per line served. One data byte is a make byte and the other a break byte. When a line is scanned its two bytes are read out from the RAM (3) to the receiver (1) so that one or other is amended. This amendment includes updating a set of counter bits which define the number of scans for which the line has been in the same state. Any change of state is noted by stopping one count and starting another count. However, the counter bits for the stopped count are not automatically cleared when a change of state is detected. Such clearance is only effected when the change of state is such as to necessitate a further use of that counter. Thus the Make and Break bytes can store information as to the previous and present states of a subscriber's line, thus reducing the frequency at which the microprocessor has to scan the RAM contents. This releases the microprocessor for other work. The microprocessor can notify the main control equipment of such changes as that main equipment needs. When a byte is updated or amended, it is returned to the RAM <IMAGE>

Title: Apparatus and method for annealing non-ferrous strip material in a continuous drawing or rolling process
IPC: C21D9/60
Filed: 1981-01-14
Abstract: In a method for annealing non- ferrous strip material in a continuous drawing or rolling process wherein the strip material, subsequent to drawing or rolling is continuously fed around a pair of spaced pulleys, an induction coil is placed in the run between the pulleys and powered by a variable supply of suitable frequency. One of the pulleys has a double grooved electrically conducting rim which electrically short circuits the incoming to the outgoing strip material thus creating a single turn short circuit around the pulleys thereby forming a movable, short circuited secondary winding of the induction coil serving to heat the strip. The required annealing temperature is controlled by controlling the power to the induction coil. A combined quenching and annealing apparatus is also disclosed for quenching the annealed strip material after annealing. The quenching apparatus employs means for maintaining the level of the quenching fluid constant. <IMAGE>

Title: Seed storage and planting
Inventor: BRITTON JOHN CHARLES
IPC: A01C1/04
Filed: 1982-01-04
Abstract: A seed carrier comprises an elongate rope-like member (1) formed of a number of strands (2, 3, 4) made of fibrous material such as sisal hemp or one or more grasses. The rope is subjected to a slight reverse twisting action so that the strands separate slightly, and seeds (5) are introduced between the strands at intervals along the rope. The seeds may be attached to the strands by adhesive. The reverse twisting is then discontinued, so that the strands return to their normal tight-wound state, but with the seeds trapped therebetween. The seeds are planted by laying the carrier in contact with the soil. The strand material decomposes, and the seedlings grow in a row with a predetermined spacing therebetween. The number (1) provides the seeds with protection against consumption by animals, insects and birds, and also protects the seeds from the wind and rain. <IMAGE>

Title: Flow box
Inventor: EYNON DAVID LESLIE
IPC: D21F1/02
Filed: 1982-07-02
Abstract: The flow box comprises an explosion chamber, having a base wall, top wall and two side walls. An outlet at the bottom of one side wall communicates with a slice chamber extending parallel to the base wall, and the number of inlet pipes connect the explosion chamber to a distribution chamber. The inlet pipes communicate with two rows of openings in the top wall of the explosion chamber and have an axial direction directed towards the base wall. A fist deflector has an upper surface which extends across the axial direction of the pipes of a first row of openings to form a divergent passage with the top wall. A second deflector extends from the other side wall across the axial direction of the pipes of the second row of openings. The second deflector has an upper surface forming a convergent flow passage with at least a part of the lower surface of the first deflector. - The flow box or head box is used to supply paper stock to a forming wire during the papermaking process. It provides a more uniform distribution of the stock across the width of the wire giving reduced variation of basis weight of the final web in the cross-direction.
Patent GB-2142757-A (GB)
Title: Improvements in and relating to fire and explosion detection and suppression
Inventor: ALLEN NICHOLAS SIDNEY
IPC: G08B17/12
Filed: 1983-05-21
Abstract: A fire and explosion detection system for responding to certain fires and explosion (e.g. hydrocarbon fires) but discriminating against other fires and explosions (such as an exploding ammunition round which does not cause a hydrocarbon fire) is described, such as for use in a military vehicle. A unit 5 sends signal A HIGH both in response to a hydrocarbon fire and also in response to the flash from an exploding ammunition round. This triggers a 100 mS monostable 52 and holds gate 56 closed through inverter 54. If the ammunition round ruptures the vehicle fuel tank a pressure or similar transducer 65 sends signal H HIGH and produces a fire alarm signal I which passes through OR gate 58 to an output 80. If the round does not rupture the fuel tank, gate 64 is held closed and no alarm is produced. However, if fire persists for more than 100 mS, even if the fuel tank has not been ruptured, a HIGH signal A causes a HIGH fire alarm signal F through gate 56 and thence to output 80. <IMAGE>
