Title: Eccentric drive for keyhole saw - has cross stroke imparted via rotary plate adjusted support roller on sprung lifting arm
Inventor: BERGLER OTTO
IPC: B23D49/16
Filed: 1976-11-04
Abstract: The keyhole saw has an eccentric drive for the blade which executes an additional, adjustable cross stroke via support roller arranged on a spring loaded lifting arm. The roller moves backwards and forwards and is controlled via an adjuster. The adjuster comprises a rotary plate (20) to which the swivel point (19) of an arm (18) with a lift arm (24) control cam (23) is fitted. The cam is so formed that according to the position of the rotary plate (20), it is movable to an adjustable extent over a hypothetical circle, the centre of which is the plate (20) rotary axis. The radius corresponds to the distance of the rotary axis (21) from the lift arm (24) in its outgoing position. The support roller (27) imparts small adjusting movements to the saw blade in this position.

Title: Deasphalting of oils with carbon black - followed by solvent extraction
Inventor: SOYEZ WERNER DIPL PHYS DR
IPC: C10G21/00
Filed: 1977-05-09
Abstract: Mineral oils and/or oil residues, or their substitutes from coal, oil shales or tar sand are de-asphalted by solvent extraction in pressure of carbon black obtd. from partial gasification or combustion processes. The black is pref. used in the form of pellets, as obtd. when black is removed from the waste water from gasification or combustion processes by treatment with sol. Yields up to 95% can be obtd. compared with 40-60% by known processes e.g. distn., Vacuum distn. or solvent extraction. Higher boiling solvents esp. those with 5C atoms or more, can be used without increasing the metal content of the extracted oil. The used black pellets can be burnt in boilers or re-processed.

Title: Carton sheet cutting waste removal device - uses pins attached to links of endless chain and brush for removing engaged waste pieces
IPC: B26D7/18
Filed: 1977-06-02
Abstract: The machine for removing waste pieces is used in carton sheet cutting. Pointed pins are inserted into waste pieces and tilting pins remove waste from cut pieces. The arrangement operates accurately and with sheets of different sizes. The pins (2) are moved parallel to the precut carton sheet (1) travel. Pins and sheet move at exactly the same speed and pins are tilted away when the piercing is completed. The pins are arranged on links (3) of an endless chain. The pins engage with waste pieces and these are swept away from the pins by a rotating brush. The latter is arranged under lower span of the chain after the links have left return roller (23). Hence the pins are cleared before they reach the other drive roller (24).

Title: Blast cleaning of austenitic steel surfaces - involves removal of ferritic contamination with mixture of corundum and a carrier fluid (OE 15.5.78)
IPC: B24C1/00
Filed: 1977-07-14
Abstract: Ferritic contamination of the surface of austenitic steel is removed by means of a blast of a mixt. of corundum and a carrier fluid, the pressure being provided by compressed air. The fluid/corundum mixt. contains from 40-90 vol. % corundum particles, the particles being triangular in facet and varying in size between 0.2-0.6 mm. The air pressure is 2.5-5.5 atmospheres. A minimum of 0.8-3 kg. of corundum particles are required per 100 cm2 of surface to be cleaned. The blasting is followed immediately by washing with a cleaning fluid, pref. a soln. of salt-peter acid, to prevent the re-adhesion of the ferritic particles. The corundum particles can be recycled up to 50 times with no detriment to the cleaning process. The method is of particular value in cleaning the surface of the stainless steel sheaths used in the production of atomic power. The procedure using a lower blasting pressure yields a clean surface with no need for further mechanical cleaning. The washing leaves a surface in which any remaining ferritic material is readily visible. Cracks remain open so that they are also revealed by a visual inspection.

Title: Single-lever mixer valve assembly - has slotted valve piston shank with retaining cap for easy dismantling
Inventor: GROH GUENTHER
IPC: F16K11/078
Filed: 1977-08-12
Abstract: The mixer valve comprises a housing (1) with a swivel bearing for the operating lever (3)(4)(5). The valve piston moves vertically (7) and is fitted with O-rings for sealing in the cylinder of the mixer mechanism (8). The upper shank of the piston is formed into a fork whose arms are slotted horizontally (14). The slots extend over half the width of the shank. A cross pin (15) which passes through the inner end of the operating lever, engages with the slotted recess in the arms. To prevent the pin from being dislodged from the slot, a retaining cap is pushed over the upper end of the piston. The sides of the cap have key-hole slots to accommodate the projecting ends of the cross bolt and a vertical slot to allow for movement of the operating lever.

Title: Improving the texture of continuously cast steel - by feeding solid steel wires into solidifying mould contents
Inventor: BAUER KARL HEINZ DIPL ING
IPC: B22D11/112
Filed: 1978-02-06
Abstract: The texture of a continuously cast strand of steel is improved by the addition of solid iron in the mould where it melts before the metal in the latter solidifies. The solid iron is introduced in the form of wire in the mould at a higher velocity than the extraction rate of teh strand. This reduces the segregation of the strand by widening the globular zone (from 10 to 52% of the strand thickness) through using up heat from a superheated melt. The quality of the cast steel strand is improved and the casting rate can be raised.

Abstract: The system for fighting of ground targets uses a guided missile with final phase control ensuring almost vertical approach to the ground target. This missile is used for fighting targets outside vision range. The missile approaches the target over long distance with low level flight. I flies upwards in the direct target area, and after reaching sufficient height for final phase it reverses its flight direction and approaches the target vertically. The projectile is precision controlled during its end phase of diving on the ground target.

Title: Dental and medical X=ray appts. - has X=ray absorbing shield extending forwardly above and below, and rearwardly of beam target
Inventor: WEISS MORTIMER E
IPC: A61B6/14
Filed: 1978-06-20
Abstract: The dental X-ray apparatus comprises an X-ray tube providing an electron beam, and a beam target carried by the tube and located axially rearwardly of it to be received rearwardly into a patient's mouth. The target is angled relative to the axis to produce a radiation pattern that extends forwardly of the target and also rearwardly and sidewardly of the target. The X-ray tube includes a structure to cause the electron beam to form a beam impingement spot on the target of sufficiently small size that radiation emanating from the spot and directed toward a tooth and film produce a sharp boundary tooth image on the film. An X-ray absorbing shield adjacent the target rearwardly of it and extends forwardly at the side of the target. The shield defines a probe that projects rearwardly for reception into the patient's mouth.

Title: Essential oil containing stick - coated by metal film preventing discoloration from wooden or plastic shell
IPC: A45D40/20
Filed: 1978-08-05
Abstract: A stick of fatty substance containing essential oils or other components such as perfumes in embedded in a wooden or plastic outer sleeve. The stick has been coated before insertion with a layer which is impermeable to the liq. as well as the gaseous phase; the sheath can be applied by vapour deposition of a metal or in the form of a metal foil. This prevents the essential oils from migrating from the stick into the wood and dissolving substances in the wood, thereby causing a disolcouration. The same may occur with plastic sleeves.
