Title: Loading very long tubes sideways into reheating furnace - using reciprocating drum feeder mounted on inlet wall of furnace
Inventor: JOUR J M
IPC: F27D3/00
Filed: 1975-07-23
Abstract: Loading device is for a furnace employed to heat treat metal tubes. A long horizontal opening is provided in the inlet wall of the furnace, and closed by a drum mounted on a swivel shaft so the drum can be reciprocated between two positions. In one position, the tubes can be fed one at a time into a V-groove on the drum periphery, and, in the other position, the tube rolls sideways into the furnace. A curved shield is pref. mounted on the inlet wall above the drum to limite the escape of fumes from the furnace. Device is used for side loading of very long tubes (e.g. over 30 metres long), esp. seamless tubes which are reheated before travelling to a sinking or reducing mill. High loading speeds can be used, but heat losses are kept to a min.

Title: Immersion type liq. cooler - has spiral pipe delivering coolant from compressor in contact with evaporator external wall
IPC: F25B39/02
Filed: 1976-09-13
Abstract: The immersion cooler has an evaporator for immersion in a liquid and shaped so as to enclose a central space for the liquid, through which a current is generated by an agitator. A pipe delivers coolant from the output of a refrigerating compressor via a condenser to the evaporator, which is connected at the top to the compressor intake. The pipe (5) runs in a spiral pattern inside the evaporator (3) for its entire length, being in contact, for heat transfer, with the evaporator wall furthest from the central space, thus preventing ice formation on the outside of this wall in service. The evaporator itself can be a spiral tube.

Title: Axle changing system for different gauge railways - has gantry crane to position axles after wagon body is hoisted clear
Inventor: GENTIL MARC LOUIS
IPC: B66C19/00
Filed: 1977-01-27
Abstract: At the frontier between countries with different railway gauges, the axles of railway wagons are changed with wheels to suit the railway gauge as this is more efficient than transferring the contents of the wagons. A travelling gantry train can be used to facilitate this changeover. The wagons (21) are hauled into the shed (20) on rails (22) with rails on either side supporting axles of both gauges. The axles are disconnected from a wagon which is then hoisted clear, allowing the travelling gantry (24) to pick up the discarded axle and transfer it to the storage rails. A replacement axle of the required gauge is then picked up from a storage rail and placed on the track ready to receive a wagon.

Title: Structural analysis appts. for monocrystal - utilises processor control of crystal rotation for recording reflected ray indices and intensity
Inventor: GALY JEAN
IPC: G01N23/207
Filed: 1977-02-07
Abstract: Detailed structural analysis of a fragile crystal such as protein is performed by measuring diffraction of X-rays to obtain reflections as the crystal is rotated. The reflections are detected for recording. A crystal (2) is subjected to bombardment of X-rays through a collimator (3). Two linear position detectors (4) are located on a turntable (5) moved by step motors (6, 7). A third step motor (8) rotates about a vertical axis (mu). Optical benches (9) permit movement of the detectors relative to the crystal. The crystal is rotated under processor control to accumulate detector data of reflected X rays on storage discs. The indices and intensities of the reflexions are calculated for each plane.

Title: Liquid quenching large steel parts - using pressurised gas above liquid bath to increase cooling rate
IPC: C21D1/63
Filed: 1977-03-03
Abstract: Metal parts are heated to a specified temp. and then quenched in a liq., where the surface of the liq. is subjected to a pressure above atmos. press., pref. up to 2.5 bars, esp. using a closed system and 1.2-2.0 bars. The pref. process consists of quenching parts made of ball bearing steel in oil which is stirred and subjected to a surface press. of 1.2 bars, esp. raising the press. so the oil remains below its b.pt. The pref. plant consists of a vacuum furnace with a quenching chamber fed with pressurised inert gas and fitted with a safety valve; the quenching medium is pref. provided with stirrers. Used e.g. in the hardening of 300 kg ball bearing races. The cooling speed of the steel is increased (e.g. by 30%) so that variations in hardening efficiency are completely eliminated.
Patent FR-2386705-A1 (FR)
Title: Pump for washing machine or dishwasher - has by=pass pipe to prevent surging when inlet flow ceases
Inventor: PETOUILLAT DANIEL
IPC: F04D15/02
Filed: 1977-04-06
Abstract: the pump of a washing machine or dishwasher has an impeller (10) driven by an electric motor (2). Water enters by the inlet (8) and flows into the impeller chamber (5) and is expelled through the delivery pipe (9). When the flow of water to the inlet ceases, air is drawn in. The presence of air reduces the delivery pressure of the impeller so that the column of water in the delivery pipe flows back into the pump causing an oscillating or surging flow which creates undesirable noise. This surging can be eliminated by connecting the inlet (5) to the impeller chamber (6) to a point (12) upstream on the delivery pipe (9) by a by-pass pipe (11). This allows the water to circulate in a closed circuit when the flow from the machine to the pump ceases.
