Title: Dehydrogenation catalyst
Inventor: LEWIS GREGG E
IPC: B01J27/232
Filed: 1988-08-15
Granted: 1993-06-01
Abstract: ABSTRACT       This invention relates to a dehydrogenation catalyst containing iron and promoted with potassium and cerium which has been shown to have improved activity when a copper compound is added thereto as a component.  The improvement in activity is obtained without substantially sacrificing selectivity.  While copper has been employed as a stabilizer in some iron dehydrogenation catalysts, its combination with cerium in the presently disclosed catalyst composition is novel.

Title: Repetitive arc cutting of continuous sheeting
Inventor: LANDECK HARRY A
IPC: B26F3/00
Filed: 1988-09-09
Granted: 1993-02-09
Abstract: D-15,568 ABSTRACT OF THE DISCLOSURE   A process and apparatus for making a repetitive arc cut in a continuous manner in a continuous supply of sheeting possessing edges, which involves providing a moving sheeting across a cutting area and passing through the area an arc-directed omnidirec-tional cutting means at and across an edge, in the general direction of the sheeting, to puncture a portion of the moving sheeting, maintaining the arc directed velocity of the omnidirectional cutting means at a rate equal to or less than that of the directional velocity of the sheeting such that the puncture is enlarged to a lineal cut. The most favorable application of the invention involves the use of waterjet cutting to cut holes, especially primarily round holes, in multi-wall plastic constructions.

Title: Continuous casting apparatus and method
Inventor: GERDING CHARLES C
IPC: B22D11/06
Filed: 1988-10-12
Granted: 1993-07-20
Abstract: Continuous Casting Apparatus and Method Abstract  of the Disclosure Apparatus for continuously casting strip material comprising a casting drum rotatable about a first axis, a pair of cheek members including portions slidably engageable with sides of the casting drum mounted for rotation about a second axis spaced from said first axis and a casting belt wrapped around a portion of the cheek members together defining a converging casting arc.  The cheek members include peripheral surfaces engageable by marginal edges of the casting belt which maintain a variable casting gap between a casting surface on the belt and a casting surface on the drum. The eccentric mounting of the cheek members with respect to the casting drum cause the spacing between the belt and the drum to decrease as the end of the casting arc is reached.  The cheek members each include tapered side surfaces which together with the casting drum define ear receiving recesses that increase in a radial direc-tion as the end of the casting arc is approached.  The ear receiving recesses thus defined permit a liquid metal pool to exist which is of considerably greater depth than the height of the ears cast by the machine. The principles of the invention are also disclosed in connection with an in-the-ring (ITR) type machine, a bessemer type machine and a converging belt type machine.

Abstract: GUIDING AN END CONDUCTION STRIP OF A WEB FORWARDLY FROM A ROLL     ABSTRACT OF THE DISCLOSURE          Method and apparatus for guiding and directing an end conduction strip of a web from a smooth-surfaced roll, such as a paper web in a press.  The end conduction strip is detached from the smooth surface of the roll and further guided by utilizing a guide plate and air blowing actions.  An air jet having sufficiently great impulse is directed against the end conduction strip on the roll surface.  The end conduction strip is cut with the aid of this air jet and a leading edge thereof is detached by this air jet from the roll surface.  The detached end conduction strip is further guided and conveyed forwardly by a transfer blowing action.  This transfer blowing action is directed along the guide plate.  An under-pressure field is produced in conjunction with the guide plate, by effect of the blowing action.  The effect of this under-pressure field causes the end conduction strip to be further guided in a direction determined by the guide plate.

Abstract: The polarizable electrode in an electrolyte comprises an electrically conductive conductor, advantageously metal or carbon, which is surrounded by an inner layer made of an electrically conductive plastic, which has a high stability to action by the electrolyte and does not lose its closed structure on insertion of the electrode so that protection of the electri-cally highly conductive conductor against electrochemical or chemical action is guaranteed.  The inner layer is enclosed by an outer layer made of electrically conductive plastic, which loses its closed structure by the electrochemical processes occurring and which expands to a large volume so that the active working surface of the electrode is increased by the desired porosity.

Abstract: A printing mechanism is described comprising a plurality of type carriers (12, 34) which on their outer peripheral face carry in one region printing types and in another region indicator types (44). The printing types can be brought by turning the type carriers (12, 34) into a printing position. A setting means (32, 20, 24) including an actuating knob (32) can be brought into a drive connection with each of the type carriers (12, 34) for rotation thereof. Stop means (100, 102, 104, 106, 110) limit the turning travel of the type carriers (12, 34). With a detent moment governed by their spring hardness resilient detent elements (96) hold the actuating knob (32) against a rotation relatively to the type carrier (12, 34) in drive connection with the setting means (32, 20, 24), the detent moment being greater than the torque necessary to rotate the type carriers (12, 34). A setting member (112) for influencing the spring hardness of the detent elements (96) can be brought into engagement with said detent elements (96).

Abstract: PCT No. PCT/EP85/00160 Sec. 371 Date Dec. 5, 1985 Sec. 102(e) Date Dec. 5, 1985 PCT Filed Apr. 9, 1985 PCT Pub. No. WO85/04548 PCT Pub. Date Oct. 24, 1985.In a cutting head for an electric-motor-driven filament-type cutter the automatic adjustment of the length of the filament is effected in that intermittently a rotational movement occurs between a filament spool (36) and a sleeve (24) mounting said spool for axial displacement. The sleeve (24) is provided on the outside with locking cams and the filament spool on the inside with cams cooperating therewith. The sleeve (24) can be pushed in by hand against spring pressure to cancel the intermittent locking. For automatic filament adjustment a centrifugal adjustment is provided. For this purpose at least two radial ball slots (40) are provided between the housing portion (14) and a radial extension (48) of the sleeve (24) and in the ball slots balls (44) are guided which are adapted to be urged outwardly by centrifugal force. Since the height of the ball slot varies over an inclined plane (42), when the balls (44) move radially outwardly a spreading of the two parts (48, 14) takes place so that intermittent unlocking results. The individual rotational angle portions are limited by lower and upper cams which cooperate with a counter cam which is controlled by the displacement movement and cooperates alternately with the one or other cam, the sectionwise or intermittent angular displacement taking place by repeated switching on and off of the motor.

Abstract: A method of introducing supply air into a lower portion of a room space (3) directly to an occupied zone (7) by means of at least one elongated air distribution means (1) provided with a plurality of outflow openings (2) for supply air. In order to blow supply air into the occupied zone without draught and without drawing impurities from the upper portion of the room space, supply air is blown from the air distribution means at a high speed but through outflow openings so small that the speed of the air jets (A) from the openings is reduced essentially over a short distance (X) and the entrance of secondary air (B) from the room space into the air jets is prevented in the vertical direction of the room space over said distance (X) and at least at one end of the air distribution means. The air distribution means (1) is provided with a plurality of small outflow openings (2) the distance of which from each other in the longitudinal direction of the air distribution means is great as compared with the size of the outflow opening for enabling secondary air to flow from the room space in between the outflow openings, and to mix with the air jets from all sides.
