Title: Joints for concrete tubes for lining tunnels - prevents leakage while metal reinforcement is being welded
IPC: E21D11/38
Filed: 1976-09-15
Abstract: The method of joining applies to concrete tubes (1) with a metal reinforcement (5, 6), used to line tunnels. The end section (1a) of the concrete tube is reduced in dia. and has a ci rcumferential groove (1b) to receive an 0 ring (2). A metal sleeve (3) is fitted over the 0-ring of one section of tube and the next section is then fitted into position. The sleeve (3) then forms a seal with the 0 rings (2) and enables an inner metal sleeve to be fitted which overlaps the ends of the reinforcing tubes (6a) and is then welded in position to make a permanent joint. The use of the outer sleeve (3) and 0-rings (2) avoids the risk of the welding of the inner sleeve being hampered by leakage.

Title: Surface type heat exchanger - has fins cast in rigid sole plate with embedded depth greater than fin thickness
Inventor: COUTURIER GEORGES LE
IPC: F28F21/08
Filed: 1976-10-27
Abstract: The surface type heat exchanger has parallel closely spaced fins (1) projecting from a sole plate (4). The fins and the sole plate are respectively of aluminium sheet and aluminium alloy, and the fins are cast into the sole plate. The assembly is made in a foundry and by pouring molten aluminium alloy into a recessed sole plate. The fins project in on one major face, and as a result the outer sectors of the fin are simply embedded and the inner sectors are fused with the sole plate. The depth of fin embedded may be not less than the fin thickness and the fused depth may depend on the relative thermoconductive properties of the constituent material of the fin and the sole plate.

Title: Rotating temp. raising device for liq. and gases - generating heat by shaft in PTFE bearing
IPC: F16C33/20
Filed: 1976-10-29
Abstract: Temp. raising device, capable of dealing with liqs. or gases either corrosive or not, comprises a shaft rotating in a PTFE bearing; heat is produced without seizing and may be used for the generation of steam or for distn. The shaft rotates in the bearing which is mounted in a rigid steel bushing. The shaft has turbines at each end; a pump, which may be on he same shaft, sends the liq. under pressure between the shaft and the bearing and a packing seals the front part of the appts. The heat generated by the friction of the shaft in the bearingg is carried by the liq. which is evacuated at the outlet where a valve adjusts the output accoding to the temp. required; this can vary between 30 and 200 degrees. This temp. is limited only by the characteristics of the PTFE used. This simple system for transforming work into heat can be used for pasteurisation, sterilisation or vapourisation of the liq. treated. The small turbine renews the pressure of the liq. at the outlet. For distn., this turbine communicates with the hollow portion of the shaft whilst the larger turbine creates a reduced pressure in the shaft; the valve is adjusted so that the liq. boils. The vapours rise and are sucked out by the larger turbine; the shaft then acts as a heat exchanger the hot vapour condenses and heats the entering liq. Device is of a novel conception and is simple but robust. The yield is high because PTFE is an excellent insulator; there is practically no wear.

Title: Water closet for animals - uses weight of animal on platform to cause operation of flushing syphon with discharge to reservoir which may be emptied by pump
IPC: A01K1/01
Filed: 1977-03-21
Abstract: A support (1) for the animal is made in two halves which are removable to facilitate cleaning. Sand or sawdust to attract the animal is released on to the support from openings (16) in reservoirs (17) arranged on either side so as also to guide the animal into the correct position for releiving itself in the receiver (4). The support has openings over a compartment (3) in which the sand or sawdust accumulates. The weight of the animal causes the opening of a valve to admit water at (6) to flush away the excrement and urine to a reservoir. A float switch activates a pump for evacuating the reservoir.

Title: Providing tube with welded fins - by applying successively electric current to fins located on the tubes
Inventor: SIMOEN IVAN
IPC: B23K11/08
Filed: 1978-01-13
Abstract: A process for welding elements such as fins on workpieces such as tubes, involves providing slots by cutting on a position of the length of a strip so as to provide on the length of the strip a cut portion and a non-cut portion. The strip is folded so that the fold is approximately parallel to at least one of the edges of the strip. The strip is rolled around a tube to be provided with fins, the non-cut part of the strip being applied at the workpiece periphery to constitute the base of the fin so that the cut part is opened in the form of a fan so as to form segmented fins. A roll is supported on the base of a fin so as to impart successively to the base of each fin and to the tube an electric current from a generator. Another roll is supported on the base of another fin in contact with the tube so as to close the circuit to the generator. The rolls and tube are rotated relative to each other so that the heat produced in each successive contact of the fin and tube provides welding of the fin on the tube. The invention avoids the formation of a deposit of copper on the tube.
