Title: Method of producing steel-strip cutters for use as one-way cutters in planing machines
Inventor: BARKE HEINER DIPL KFM
IPC: B23P15/28
Filed: 1983-01-04
Abstract: A method of producing steel-strip cutters for use as one-way cutters in planing machines, with mating holes for mating pins of a cutter holder, is to be improved in such a way that not only is the manufacturing process simplified but the strip-steel cutters produced by the method no longer have any curvature, can thus be used in any length and can no longer fracture, and the holes can be made exactly. This is achieved in that the endless strip steel is hardened only in the subsequent cutting-edge area to be ground, that cutting edges are ground on one or both sides of the strip steel after the hardening, that the individual cutters are cut to length from the endless strip steel, and that the mating holes are made in the part of the strip-steel cutters which is not hardened.

Patent DE-3310612-A1 (DE)
Title: Boxing glove
Inventor: CASS GEORGE RODNEY
IPC: A63B71/14
Filed: 1983-03-23
Abstract: The invention relates to a boxing glove having a finger region and a thumb region. Since abduction of the thumb may lead to injury of the thumb, while it may also adversely affect the opponent, for example by injuring the opponent's eye, it is desirable to prevent such abduction. Furthermore, this aspect is to take account of the possibility of cramps due to the permanent clenching of the fist. For this purpose, there is provided a strip, preferably made of leather, which connects the thumb region with the finger region. The resultant limitation of movements of the thumb region relative to the finger region reduces both the probability of an injury to the thumb of the boxer and at the same time the risk of injury to the opponent and, in particular, injury of the opponent's eyes.

Patent DE-3429851-A1 (DE)
Title: Test device for pressure-limiting valves
IPC: F16K37/00
Filed: 1984-08-14
Abstract: A test device is used for determining the opening and closing pressure of, in particular, pressure-limiting valves, in the case of which test device a closed hydraulic circuit having a pump, a supply container and a control valve is allocated to the pressure transmitter and in the case of which the pressure-valve connection holder is connected to the pressure side of the pressure transmitter in a second closed water circuit. The closed water circuit, or even water in an oil-emulsion circuit, permits environmentally friendly and safe operation of the test device, because the return of the pressurised water can be supplied as an unpressurised medium to the compression-piston housing, and hence to the compression piston again. Via a rapid-emptying valve, care is taken to ensure that a rapid movement sequence takes place when the piston and the differential piston move back, which is ensured by low differential-pressure-area differences. <IMAGE>

Patent DE-3437965-A1 (DE)
Inventor: HUELLER ROLF
IPC: B01D53/34
Filed: 1984-10-17
Abstract: The removal of SO3, sulphuric acid and sulphuric acid mists from flue gases of wet desulphurisation plants in the combustion of sulphur-rich coals is improved by spraying at least one separator layer of a demister system with a quantity of caustic soda, soda, aqueous ammonia or mixtures thereof, which is in excess relative to the total residual quantity of sulphuric acid in the gas. About 95% of the residual sulphuric acid in the pure gas can thus be removed. The alkali solutions flowing back into the reaction vessel do not interfere with the remainder of the desulphurisation process and the formation of large gypsum crystals.

Title: Lateral laying device
Inventor: DREHER ANTON
IPC: B65H54/28
Filed: 1984-10-18
Abstract: A lateral laying device (SV) is proposed which has a linear drive (1) for a guiding device (2). The guiding device (2) essentially consists of two vertically upright guide rollers (3, 4), one of which is mounted so as to be stationary in relation to the guiding device (2) and the other is mounted on the guiding device (2) so as to be laterally displaceable. Material which is to be wound up can be guided between the two guide rollers (3, 4) to a winding head. So that the individual coils of the wound-up material are situated close together, lateral displacement of the guiding device (2) is accordingly monitored by a control system. The lateral laying device can be used for different winding heads and material to be wound of different diameters by the input of corresponding data. <IMAGE>

Title: Arrangement for the cross-connection of bar-shaped profiles
Inventor: FIVIAN MARTIN DANIEL
IPC: F16B3/00
Filed: 1984-11-29
Abstract: In order to construct structures which can be easily assembled and are in the form of a framework, the present arrangement exhibits a joint element (2) via which a first round profile rod (6) can be connected in a cross-shaped manner to a second round profile rod (6'). In order to effect the actual connection, corresponding recesses (8, 8') are provided on both round profile rods, the actual connecting point being located in the interior of the joint element. During assembly, the first round profile rod (6) is inserted into a first bore (4) of the joint element (2) such that the second round profile rod (6') can be guided, via a second bore (10), far enough through the recess (8) of the first profile rod (6) to permit the two recesses (8, 8') to engage in each other. To ensure against unintentional detachment from the assembled position, the two connected round profile rods (6, 6') are then braced in the joint element (2) via a wedge element (12). <IMAGE>
Patent DE-3444020-A1 (DE)
Title: Chimney top
Inventor: KRECKL SEN ANTON
IPC: F23L17/02
Filed: 1984-12-03
Abstract: The invention relates to a chimney top with a hood or plate covering the chimney opening. As the free space between the upper edge of the chimney top, which consists of four side walls, and the chimney hood is not sufficient for cleaning the chimney, the hood usually has to be removed or pivoted away with the aid of a hinge for cleaning. As the chimney hood constitutes a large application surface for the wind, folding away the hood is problematic. The invention therefore proposes to design not the hood (2) but a side wall (1) of the chimney top to fold down. So as not to weaken the structure of the chimney top by this measure, the invention envisages, in addition to a pivoting device (10), a locking device (12) which makes possible a three-dimensional anchoring of the fold-away side wall (1) with the ends of the adjacent side walls (2, 4). <IMAGE>
