Title: Induction heat treatment of steel tube - using brief surface quenching to above martensite transformation point, then slow cooling
IPC: C21D9/08
Filed: 1976-01-31
Abstract: A steel workpiece, esp. a tubular piece, is heat treated by austenizing and quenching, where the workpiece travels at a prescribed speed through heating and quenching zones. In the quenching zone, the workpiece is briefly quenched from its outer surface continuously to above the martensite transformation point, and the heat remaining in the workpiece is used for the formation of intermediate structures; the workpiece then cools to room temp. After brief quenching, heat is pref. used to assist in forming the desired structure. The pref. plant includes a brief quenching zone of adjustable length. (In an example, an induction heating coil is followed by water quenching coils, and then by a short induction coil used to supply heat during the cooling of the workpiece). Used for the quasi-isothermal transformation of steel tubes. Reduces the cost of plant required for the hardening and tempering of tubes, esp. thick-walled tubes.

Title: Multicolour diazo copying by subtractive process - using impermeable transparent film carrier for each diazo prepn.
Inventor: MEYER REINHOLD DIPL CHEM DR
IPC: G03C1/52
Filed: 1976-06-05
Abstract: In prodn. of multicolour diazo copies by subtractive colour mixing using partial colour images, the first colour image on a carrier is covered with a diazo prepn. on a transparent intermediate carrier. This is exposed to light and developed to form a second colour image of the original, exactly superimposed on the first image. The process may be repeated, using a diazo prepn. each time which couples to give a different colour. The intermediate carrier is impermeable to the diazo prepn. and developer. It is pref. a polyester film. Use of a separate, impermeable carrier for each diazo prepn. prevents diffusion of developer residues, esp. ammonia, left from development of preceding colour images, causing premature coupling.

Title: Clamp holding sand lime bricks - which prevents damage when moving green bricks from a press to a hardening plant
Inventor: BRAND HEINZ
IPC: B65G49/08
Filed: 1976-07-16
Abstract: Device for clamping pressed stone blanks during the mfg. of bricks, esp. lime sand bricks. The clamp has a traverse fitted with actuators for two outer clamping jaws (1, 2) which are located on the outside surfaces of two blanks. Between the inside surface of the two blanks is a pair or clamping jaws (3, 3') fitted on a pivot shaft and held together by a tension springs. The inside surfaces of jaws (3, 3') have a wedge-shaped profile mating with the two tapering surface of a wedge mounted on two rods attached to pivots. When the wedge is raised, e.g. by a work cylinder, jaws (3, 3') are forced outwards away from each other, thus clamping the two stone blanks against jaws (1, 2). After pressing sand lime bricks, the green bricks must be transferred to a hardening trolley or a conveyor while they are still weal. The invention provides a clamp which can pick up two bricks while there is a gap between the bricks. i.e. the latter do not have to be pressed together and can thus be transferred to a hardening appts. without damage.
Patent DE-2638450-A1 (DE)
Title: Picker of thermoplastic material with carbon fibres - with increased heat resistance without increasing hardness
IPC: D03D49/36
Filed: 1976-08-26
Abstract: Picker for loom is made of thermoplastic material with C fibres which pref. have a staple length of 4-10 mm. and comprises 5-10 wt. % of the mixt. Alternatively, the picker has an insert, and only the insert contains C fibres. Although the C fibres have a very high modulus of elasticity, the tensile and bending elasticity modulus i.e., the hardness of the picker is only slightly increased with 10% of short C fibres added to flexible polyamide, while heat resistance is increased. Due to the good slip properties of the C fibres and their thermal conductivity, wear properties are improved. With normal pointed shuttles, the good slip properties allow only slight heating of the shuttle tip.

Title: Surface oxidising stainless steel - to form spinel layer which is easily removed by pickling
Inventor: BOGGS WILLIAM EUGENE
IPC: C23G1/08
Filed: 1978-02-27
Abstract: Stainless contg. >=11% Cr is surface conditioned to form an oxide layer which can easily be removed by conventional pickling, by heating to between 1700 degrees F and the liquation temp. in an atmos. of oxygen potential such that the log of the oxygen partial pressure (log PO2) is in the range (-29280/T) + 5.6 to (-27840/T + 8.1 (where T is the absolute temp., degree K) to form a surface oxide layer primarily of FeCR2O4 spinel, cooling and pickling in a conventional carbon steel acid pickling soln. to remove the spinel. The spinel is less of a barrier to further oxidation than CR2O3 so that slivers, scabs and other surface defects can be oxidised for removal by pickling. Additionally surface peaks are preferentially oxidised to provide a flat dull finish beneath the spinel. Process can be used in continuous annealing lines to provide an oxide film which can be removed more quickly, in slab or billet reheating or hot rolled strip annealing to remove surface defects before hot rolling, etc.
