Title: Pipe welding - partic the alignment, fixing, and welding of pipe lengths to flanges or rings
IPC: B23K37/053
Filed: 1973-06-29
Abstract: Flanges and rings are welded onto the ends of lengths of pipe, after alignment and fixing, by using a chucking and centering appliance. The free ends are firstly fixed to the casing surface, and the loose flanges or rings are pushed horizontally against the front face of the pipe lengths by centering members. Finally, they are tack-welded to the free pipe ends and completely welded with the centering mandrel withdrawn while rotating the pipe lengths about the roller support.

Title: Control valve for vehicle shock absorber - spring washer lifts from annular seats to control two way flow
IPC: F16K17/18
Filed: 1974-07-03
Abstract: The valve forms part of the assembly of a shock absorber. The piston rod (1) is secured to a piston (2) which is provided with a valve seat (4). A spring washer (3) fits on a shoulder (5) on the rod (1).

IPC: C23C8/58
Filed: 1974-08-01
Abstract: Molten salt bath for heat treatment of metal pieces at 450-700 degrees C, (esp. to provide nitrogen by diffusion into the metal), the main component of which is the active cyanate ion, used in amt. 20-65 wt. % w.r.t. the total mass, is characterised in that it contains hydroxyl ions from a hydroxide of an alkali(ne earth) metal in amt. 2 wt. % w.r.t. the wt. of the bath. The degeneration of cyanates in the bath is reduces to 0.5% bg wt. per 24 hrs. at operating temp. in the presence of hydroxyl ions, thus reducing both cyanide pollution and the amount of salt needed to maintain the bath compsn.

Title: Electrographic copier document transport - carriage moves forwards and back below exposure window
IPC: G03B27/52
Filed: 1974-10-30
Abstract: The forwards movement of the document transport carriage causes an exposure of the document image via means conducting the image rays onto a receiving surface in the interior of the copier, and moved in the same sense in synchronism with the carriage. During the return movement of the carriage, the means conducting the image rays are modified such that a negative of the document can be obtained, with the receiving surface continuing being displaced in the same direction, or using a second receiving surface. An optical system (8, 9) using two sets of mirrors or prisms behind an objective (66) can be displaced relative to the image beam. The first mirror or prism set (8) has its edges perpendicular to the image aperture.

Title: Reducing flexion of printing cylinder - by mounting on floating bearings inside cylinder and spaced from ends
IPC: F16C13/00
Filed: 1974-11-13
Abstract: The printing cylinder is fitted over a support shaft using internal floating bearings in the cylinder. Each bearing has spherical support surfaces which maintain correct alignment of the bearing. Due to this arrangement the reaction forces are transmitted by the spherical support surfaces to the cylinder as vertical forces, so cancelling the forces tending to bend the cylinder in the other direction. The bearings are positioned sufficiently closely together that the cylinder flexion is a minimum.

Title: Dish washer with sheet metal inside container - has angled flanges along sheet metal parts allowing continuous seam welding
IPC: A47L15/42
Filed: 1975-02-05
Abstract: The dish washer machine comprises a fluid-tight chest-like container which is formed from two sheet metal parts, one forming the side walls and top and the other forming the back and base which are joined together along their edges by rolled seam resistance welding. To ensure a perfect fluid-tight seam, the flanges of the sheet metal parts which are designed to form the seam change, in the area where the side walls adjoin the back wall, form a plane at right angles to the back wall into a plane at right angles to the side walls so that the subsequent seam welding can be carried out in one step, with the result that a continuous seam is formed.

Title: High efficiency chimney plate - forms box heating air from outside and channelling it into room
IPC: F24B1/188
Filed: 1975-02-19
Abstract: The chimney plate forms a sort of box heating the air coming from outside. This air can be regulated and directed onto the hearth, and the hot air can be emitted to a living room. The incoming air can be controlled by a perforated slide. The feet of the plate can form fire dogs, stabilising it on the base of the fireplace. The design allows the efficiency even of old chimneys to be increased, particularly when burning waster wood.
Patent FR-2281136-A1 (FR)
Title: Monitoring head for human body - has twin electrodes and lugs for sliding along support tube grooves
IPC: A61B5/344
Filed: 1975-05-29
Abstract: The monitoring head has twin electrodes forming a loop, the head fitting into a support tube made from polyethylene with the control wires passing down. Radial lugs on the head permit sliding along exterior grooves on the tube, friction preventing it falling off. The assembly fits into an outer sheath, its other end being held in a handle by a lug. The support tube passes through and is similarly fixed lower down the handle. The outer sheath prevents damage to the assembly, this being positioned and released by rotating the handle and pulling with minimum pressure to over-come friction.

Title: Dissolving plutonium dioxide from used nuclear fuel elements - in nitric acid plutonium dioxide mixtures under oxidising conditions
Inventor: TALLENT OTHAR KIMMER
IPC: B01F1/00
Filed: 1976-04-30
Abstract: A method for dissolving plutonium dioxide completely in a dissolving mixt. comprising plutonium dioxide, nitric acid and a catalytically effective amt. of fluoride, is characterised in that oxidising conditions are provided to increase the speed of dissolution, electrolytically or by addn. of silver peroxide Ag2O2. The dissolving mixt. contains and retains dissolved ruthenium. Used in reclaiming radioactive plutonium dioxide from irradiated nuclear fuel elements.

Title: Radar beam concentrator using single primary radar source - uses deflectors inclined to axis of source and having grooves perpendicular to axis, forming secondary radiators
Inventor: DUPRESSOIR ALBERT
IPC: H01Q13/02
Filed: 1976-10-29
Abstract: Energy radiated by a primary radar is concentrated by a light mechanical structure of deflectors. Wave polarisation is maintained and is rectangular or circular in a circular sector.
