Title: Automatic device for machining buttons on both faces - has turrets with clamping jaws at right angles to rotational axis
Inventor: GIUSI GIUSEPPE
IPC: B23Q16/06
Filed: 1980-02-14
Abstract: Two turrets assembled on the frame of a button processing machine turn through circles which are equal and parallel to each other. Each turret has a number of chucks which grip the buttons and have their axes at right angles to those of the turrets. One of the turrets has a mechanism occupying a central position inside it which transfers each button between the stops of two turret chucks facing each other, one after the other. Pref. the two turrets do not only have parallel axes but also have the same number of radial chucks at a minimal spacing. At each step made by the turrets, two chucks face each other near enough, and the mechanism positioned centrally inside the first turret can transfer a button from one chuck to the other, so that the work having been carried out on the one face can be continued on the other. In the new machine all the operating details are fully visible. Transport takes place between the two chucks at controlled speed, so that the buttons cannot fall out. Double turning of the surfaces of the buttons is carried out so that the tools last longer and prodn. speeds can be increased.

Title: Four-stroke reciprocal IC engine operation - reduces combustion fuel charge when there is danger of pinking or during actual pinking
Inventor: MAY MICHAEL G DIPL ING
IPC: F02D35/02
Filed: 1980-06-20
Abstract: The operation of a four-stroke, reciprocating ic engine with external ignition uses automatic detection of the approach to an instantaneous pinking limit and/or exceeding of this limit. On sensing the danger of pinking, or of pinking proper, the fuel volume is temporarily reduced in the charge for at least one combustion chamber of the engine. The fuel reduction is preferably carried out in a single step. Alternatively the reduction may be continuous, or stepwise, until the pinking stops. Then normal fuel supply is resumed, possibly after a short time delay. The fuel reduction may be attained by admixture of inactive gas, e.g. the engine exhaust gas, or a mixture of the same with air. Pure air may be also used.

Title: Gas blast circuit breaker with closing resistor - has common operating mechanism for gas compression and resistor switching
Inventor: KONRAD MARCEL CELESTIN
IPC: H01H33/91
Filed: 1980-06-27
Abstract: Mechanical operation of the circuit breaker is simplified by eliminating a separate linkage for moving the contacts associated with the switching resistor. One end of the resistor (18) has a sliding contact (22) permanently in contact with the current carrying cylinder (6) which forms part of the main moving contact (4). The main current path (14) between the cylinder and the fixed part of the circuit breaker (16) has an interruption (14b). In this area the main sliding contact (20) is open. Inside the cylinder is a piston (8) which generates the gas blast when the contacts part. When the contacts close the main path is open (14b) and current flows through the resistor until the main contacts (2,4) are almost in the finally closed position when the main sliding contact (20) again comes into contact with the main current path (14c).

The tower is then rotated to move the ladle above the casting plant. The wagon can pref. be driven in any horizontal direction; and the hoist pref. consists of a jib arm raised and lowered by a cable winch. Low cost and high safety. If the hoist should fail the jib arm is automatically clamped on its guide pillar.
Patent DE-3041607-A1 (DE)
Title: Optimum cooling of continuously cast slabs to avoid defects - where eddy current search coils monitor defects while slab is still in diamagnetic state and adjust cooling rate of slab
Inventor: CHRISTMANN BURKHARD DR
IPC: B22D11/22
Filed: 1980-11-01
Abstract: While the hot slab is still in a diamagnetic state, it travels past a row of eddy current search coils, which detect bulges and/or cracks in the surface of the slab. The measurements made by the search coils are used to adjust the vol. of cooling water sprayed onto the surface of the slab and the speed at which the slab is extracted from the mould. The search coils pref. consist of a row which is aligned at 90 deg. w.r.t. the longitudinal axis of the moving slab, esp. using one coil in the middle of the row, and one coil near the edges of the width of the slab. The control of slab quality by temp. sensors used to adjust the cooling rate is not satisfactory due to the severe operating conditions and scale on the slab surface. The eddy current search coils are not sensitive to the arduous conditions and by making measurements while the steel slab is in a diamagnetic state, the disturbing influences of scale and permeability variations are elimnated.

Title: Method and device for the wave analysis of an object using a laser Doppler vibrometer
Inventor: STOFFREGEN BERND DIPL PHYS DR
IPC: G01H9/00
Filed: 1981-04-01
Abstract: For the purpose of a planar recording of a prescribed object region using the laser Dopper effect, in which a primary laser beam is applied to the object in a punctiform way, the radiation back-scattered at the object is superimposed with a reference beam and the beat frequency of the radiation thereby obtained is evaluated, a raster-type scanning of the object region is performed by means of a mirror (9) which can be swivelled in steps about two mutually perpendicular axes. A laser Doppler optical system (6) is used in conjunction with electronic devices including a computer (21) and a memory (22) to determine characteristics for the vibrations of the individual object points, for example the wave velocity, and to store them together with local information, and a spatial image of the object vibrations is reproduced on a monitor (23). An image of the object obtained by means of a television camera (24) is laid below this vibration image. <IMAGE>

Title: Machine for folding and laying flat folding-box blanks
Inventor: KECK JUERGEN K
IPC: B31B50/58
Filed: 1981-05-13
Abstract: In a machine for folding and laying flat folding-box blanks, provision is made for only a central pair of conveyor belts to be used in order to convey the folding-box blanks through the folding station. By contrast, the folding of the lateral sections of the folding-box blanks is effected by conveyor belts running to the side of the central pair of conveyor belts and engaging under the folding box, these advantageously being supported at the rear by guide plates. To facilitate the folding operation, folding blades are provided in the intake region (up to about a folding angle of 120 DEG ) pressing from above on the folding edges, the sections of the folding-box blanks which are to be bent downwards being bent around the bottom edge of the folding blades by the increasing constriction of the folding belts. The special advantages of this machine, which is of very simple structural design, are its low production price and the fact that it can be operated and converted to various folding-box formats in a very short time even by unskilled labour.

Title: Mangle for the smoothing of damp laundry articles
Inventor: WALLBOTT MANFRED
IPC: D06F67/00
Filed: 1981-07-18
Abstract: By means of a mangle, especially damp laundry articles in the form of flat laundry are smoothed, these at the same time being dried. For this purpose, the mangle has rotatably mounted wound rollers in the form of perforated hollow cylinders connected to a suction device and fixed work surfaces in the form of bowls which can be brought into contact with these hollow cylinders and which are heated by high-pressure steam. For the purpose of saving energy, the hot spent air occurring inside the rollers is used for heating a rotatably mounted hollow cylinder (18) which precedes the rollers (12-14) in the working direction and which serves for the predrying of the laundry articles by the contact method. For the purpose of improving the drying capacity of the hollow cylinder (18), provision is made for the spent air of the rollers (12-14), before being introduced into the hollow cylinder (18), to be heated to a higher temperature by means of a heat exchanger (70) heated by the condensate of the bowls (15-17) and by the deflection bridges (54-56) or the re-evaporation of this condensate. <IMAGE>

Title: Deflection member for seatbelts in a car
Inventor: FRITSCH WALTER
IPC: B60R22/24
Filed: 1981-07-23
Abstract: In the case of three-point seatbelts for the occupants of cars, the upper belt (shoulder belt), which rolls up in a storage device, is guided by a deflection member attached to the vehicle body. It is the aim of the invention to spare the belt by substantially reducing the friction of the belt when passing through the deflection member by sheathing the metal body of said member with a plastic of a low sliding-friction coefficient. In addition, it is the aim of the invention to be able to attach the plastic sheathing subsequently to the metal part, independently of the production of the latter, and, in addition, to dimension the structure of the plastic sheathing in such a manner that in the event of an accident it is permanently deformed, allowing the functioning of the belt system to be checked thereby. The sheath is composed of a plastic moulding which can be combined with a part of the same design in a mirror-inverted fashion to form a firmly closed sheath.
