Title: Multiple heat exchanger appts. for wood fire - has ducts between hearth and hood with underfloor entry and discharge
IPC: F24B1/188
Filed: 1974-12-12
Abstract: An open wood fire associated with a multiple heat recuperation system, has a duct under the hearth, which passes air upwards past a serpentine coil also under the hearth, and alongside which is another duct which discharges heated air downwards. Also located below floor level is a blower fan which forces air upwards through a recuperator duct behind the fire, finishing just below a ventilator blade inside the hood at the top. A bundle of heat exchanger tubes with zig-zag baffles inside is positioned immediately above the hearth. Further heat exchange ducts are placed either side of this heat exchanger, and these two exchangers also terminate below the hood. The heated air passing through selected ducts is then drawn downwards through the underfloor discharge duct and used to heat a desired area.

The collar is made of semi-flexible plastics sheet (2), and is cut through by a slot (3). It is drilled with concentric holes (4) enabling the two parts (5, 6) to be fastened together with studs (7) when they are overlapped. The central aperture can be provided with flaps so as to ensure that the collar fits the trunk snugly, so that the rodents cannot squeeze between the collar and the trunk of the tree.

Title: Leak detection system for space between two walls - monitors controlled flow of nitrogen and argon mixture around space
IPC: G01N15/08
Filed: 1975-07-10
Abstract: A process or analysis system uses a method of simultaneously controlling porosity variations, to detect the onset of leakage or sealing faults, in each of the walls of a system with a continuous space surrounded by two walls. Two different fluids are kept in conact with the surfaces of the walls at opposite ends of the intermediate space. A constant flow current is set up, using a third fluid, across the intermediate space which is dept at a lower pressure than each of the spaces defined by the wall surfaces and occupied by the first and second fluids respectively. The contents of each of the fluids is measured in the current of the third fluid as it leaves the intermediate space. The contents are measured using conventional gas analysis equipment when the fluids are in the gaseous state.

Title: Feeding fibre bales across a mechanical plucker - withparallel guide ways holding bales in spaces of similar dimension
IPC: D01G7/00
Filed: 1975-12-29
Abstract: Fibres are fed from bales of fibres to the hopper of a fibre feeding machine, by defining a bale assembly area adjacent and extending longitudinally from the hopper and determining a precise location in the assembly area for each individual bale, which is supported and mechanically confined within its individual space. The location of the confined bales is co-ordinated with the operation of the automatic machine for plucking fibres from them. The plucking machine is repeatedly, automatically and selectively moved above the bales where a given amount of fibre is removed and deposited in the hopper. Process is for uniformly positioning fibre bales within bale assembly area of a mechanical fibre plucker. Each bale is so accurately confined, fibre plucker descends into its central portion.

Title: Mandrel for internal chilling of extruded pipe - to produce stress-free (polyolefin) walls
IPC: B29C48/90
Filed: 1976-05-31
Abstract: Mandrel head for cooling extruded thermoplastic pipe by passing the extrudate over a hollow, double walled mandrel incorporating circulating liquid coolant and recirculating air passing between the surface of the mandrel and the inner surface of the pipe. The liquid and the air move countercurrent to the extrusion direction: the air being recirculated through the interior of the mandrel by a fan powerful enough to ensure turbulent flow conditions. The chilled mandrel is thermally insulated from the extrusion die. The outside of the pipe is chilled by an external jacket. Used for mfr. of pipe of medium or large internal bore from high density polysethylene or polypropylene. Balanced internal and external cooling produces pipe walls relatively free from internal stresses. The air acts as a heat transfer medium between the pipe and the chilled mandrel, avoiding drag by contact with the mandrel surface.

Title: Orthogonal cursor lines generation on CRT screen - involves logging of scanning beam trajectory and comparison with stored coordinates
Inventor: LATU JEAN-CLAUDE
IPC: G09G1/14
Filed: 1976-06-17
Abstract: A method and circuit for generating horizontal and vertical cursar lines on a cathook ray tube is defined. A user selects triplets of coordinates (ZO, X1, X2) or (YO, Y1, Y2) which define the location and length of the cursors. As the screen is scanned in a raster pattern of lines (4) a memory logs beam progress. Upon reaching beginning of a horizontal cursar (2) at point (5) defined (X1, Y0) the video signal is boosted to trace the cursar until point (6) defined (X2, Y0) is attained. The vertical cursar is written by pulsed boosts of the video in each scan line between points (7) and (8) when it crosses the (X0) abscisser.

Title: Branch tee connection for pipe - has brazed on saddle piece providing alignment for boring hole in main pipe
IPC: F16L41/08
Filed: 1976-07-22
Abstract: The saddle piece (1) is used to make a T-connection between the main pipe (2) and the branch pipe (3). The saddle piece has a tubular section (5) joined a portion (4) forming part of a cylinder which is a spring fit on the pipe. The saddle is brazed to the pipe (2) and a hole (7) is then made which is aligned with the bore of the tubular section (5). The pipe (3) is then brazed in the bore of the section (5). Alternatively a coupling nut can be fitted to saddle (1) and retained by a flange formed on the tubular section (5). This type of pipe joint eliminates the need of cutting a section out of the pipe (2) to fit a screwed T piece.

Title: High pressure fired steam generator system - with 2: stage air flow control for high part: load efficiency
IPC: F01K13/02
Filed: 1976-08-20
Abstract: Generally conventional pressure fired steam generator operates at a pressure of 9 bar or more, produced by a blower driven by a gas turbine powered only by exhaust gas from the generator. Generator output is controlled by a steam pressure sensor actuated servo-system which regulates fuel flow directly and matches air flow indirectly. At high power this is done via a sleeve valve whose movement varies the discharge flow from a secondary servo-system. This in turn alters the system pressure and thence the setting of the spring-loaded servo which controls gas turbine speed by way of the gas temperature at exit from the generator. A mechanical governor maintains the selected speed in the same way. To reduce air flow at lower power further than is possible using blower speed, without a striking loss of efficiency, a further servo come into action when the speed control unit reaches a bottom limit stop. This servo alters blower stator and possibly rotor blade angles.

Title: Coil-in-shell steam generator - incorporates counter-current and parallel transfer in single-phase and two-phase flow sections respectively, reducing stresses
Inventor: SUZUOKI AKIRA
IPC: F22B1/06
Filed: 1976-11-30
Abstract: The steam generator is of the type incorporating a shell through which a heating fluid passes and a tube or coil, in the shell, through which a fluid being heated passes, partic. a steam generator using liq. sodium as heating agent, for use in a nuclear reaction power station. Counter-current heat transfer takes place in the regions of single-phase flow in which the liq. being heated, e.g. water is preheated in the liq. phase and in which it is superheated in the gaseous phase, while parallel flow heat transfer takes place in a region of two-phase flow in which the water is evaporated. The steam generator is free from the disadvantages of existing generators which use a counter-current heat exchanger. These disadvantages are that large fluctuations of temp. occur in a region where the boiling changes from nuclear boiling to film boiling, and these result in thermal stresses on the tube, leading to fatigue and to damage.
