Abstract: ABSTRACT OF THE DISCLOSURE        An optical disk storage unit has an improved access and tracking system in which a low speed velocity signal is derived from a differentiated position error signal.  The output of the differentiator is applied to a blanking circuit which disconnects the steep slope portion of the position error signal from a sample and hold circuit.  A medium speed velocity signal is derived from the integral of motor current and a high speed velocity signal is derived by digitally counting the band crossings in the position error signal.

Abstract: ABSTRACT OF DISCLOSURE     In a container defining a flexible wall, means for sealingly receiving a puncture member through the wall which comprises an insert member positioned within the container.  The insert member defines an aperture for sealingly receiving the puncture member after penetration through the wall.  The aperture provides flow communication between the container interior and a puncture member received in the aperture.  Thus, access may be provided to a container which has no conventional tubular port carried on its exterior.  Optionally, tape means may be removably adhered to the flexible wall so that removal of the tape means exposes a clean surface through which the puncture member can penetrate.

Abstract: ABSTRACT         A ballcock assembly having an upright standpipe for delivery of flush water, a control valve assembly at the upper end of the standpipe, and a float and ballast assembly slidably mounted for up and down movement relative to the standpipe and connected to the control valve assembly. The control valve assembly operates to open the valve to flow of flush water from the standpipe assembly in response to downward movement of the float and ballast assembly.  When the float assembly is caused to rise by incoming flush water from the standpipe, it ultimately causes the control valve to shut off incoming flow of flush water from the standpipe.

Abstract: Abstract of the Disclosure Apparatus for connecting a grass collector to the discharge chute of a power lawn mower.  A lower front portion of a ring around the receiving mouth of the collector is hooked over a detent at the bottom side of the chute and pivoted upwardly until an upper portion of the ring rests in a nest formed by a pair of upper tabs and a lower tab extending outwardly from a pivoted safety door.  The door is biased toward a closed position across the discharge opening of the chute, and is opened by a hook extending from an over-center latch, between the upper tabs.  The hook extends around the nested upper portion of the ring, and when the latch is manually operated to its closed position the hook pulls against the ring portion to move it and the upper part of the door forwardly.  This clamps the collector mouth to the chute, at the same time opening the safety door.  The collector cannot be removed until the safety door has been returned to its closed position by manually operating the latch to its open position.

Abstract: ABSTRACT OF THE DISCLOSURE   The present invention relates to a process for the preparation of olefins by thecracking of hydrocarbons consisting in passing a mixture of hydrocarbons and steam flowing in a cracking tube disposed inside a radiation zone of a furnace. The process is characterized in that an increase of the cracking temperature of the mixture between the inlet and the outlet of the radiation zone is associated to a non - homogeneous distribution of the thermal power of the furnace, greater at the beginning of the cracking tube than at the end, and to a reaction volume which is greater in the second half of the length tube than in the first one.   The present invention relates also to a cracking furnace in which between the inlet and the outlet of the radiation zone the diameter of the cracking tube increasesand the thermal power of the heating means decreases.

Abstract: MODULATED LASER SOURCE FOR OPTICAL STORAGE                  Abstract of the Disclosure A time modulated source of frequency doubled laser radiation is described in which a non-linear crystal part of a stripline electrical circuit is mounted within a laser cavity so that the laser beam at a fundamental frequency impinges on and propagates through the non-linear crystal. A high bandwidth electrical data signal is coupled into the stripline electrical circuit to produce an electric field across the non-linear crystal so that an output beam is produced at a wavelength corresponding to the second harmonic of the fundamental frequency which represents a frequency doubled output beam modulated in accordance with the high bandwidth data signal.     An alternate embodiment for producing the time modulated source of frequency doubled laser radiation has the non-linear crystal placed in a resonant microwave cavity.  A high bandwidth electrical signal modulates the intensity of the microwave electric field across the non-linear crystal so that an output beam is produced at a wavelength corresponding to the second harmonic of the fundamental frequency which represents a frequency doubled output beam modulated in accordance with the high bandwidth data signal.

Date Feb. 14, 1985.In this pipe connection, the pipe end part (5) is pressed, as a result of cold-forming in zones, by means of a press ring (4) to be displaced axially, to form a positive leak-proof connection with a connection piece (1) inserted into the pipe end part and belonging to a pipe fitting (2). A sleeve (3) to be pushed onto the pipe end part is provided with an annular outer bead (7) and, when the press ring is pressed on, is deformed in such a way that the sleeve material is displaced radially inwards in the bead zone (8), the pipe end part and connection piece acquiring an annular recess (9). Moreover, the press ring (4) has at its rear end an annular inner bead (10) which at the same time displaces the sleeve material radially inwards at the rear sleeve end, as a result of which further pressing takes place at the end (12) of the connection piece (1). The gap between the pipe and connection piece is thus closed, so that no crevice corrosion can occur.

Abstract: Device for load-bearing members 2 in a chassis, such as a railway carriage 1. The device comprises two locking elements 5 situated at a distance from one another, which are each provided with a cylindrical locking pin 6 supported in a guide 9. The said pin has plane faces 10 converging towards the free end of the pin 6 and is connected to the other locking pin 6 by way of a connecting link 8. The pins are axially displaceable by means of an operating element 13 so that they engage or disengage with a recess 7 in the load-bearing member 2. The locking pins 6 are moveably connected to the operating element 13 by way of a torque arm 11 and a cross 12. This forms a bearing for the torque arm 11 parallel to the axial web of the locking pin and for the operating element 13 transversely to this web. The operating element 13 is fixed to the connecting link 8, which at a distance from the bearing point of the operating element on the cross 12 is rotatably connected to one end of a spacer arm 15. This is rotatably connected by the other end to the railway carriage 1, thereby forming a resistance for the latter, it being possible to angle the resistance slightly in relation to its longitudinal axis. <IMAGE>

Abstract: The sampling device for chemical, in particular biochemical process technics, consists of a sterilizable container in which a magnetic stirring system is accommodated whose agitator beam may be adjusted in height also in operation. Fluid flows through a tangential inlet near the bottom to be discharged through an outlet provided in the upper end wall. Beneath the filter membrane there is an extremely small dead space through which the filtrate gets to the filtrate outlet. The lower end of the agitator arm is designed as a pointed flow break-away edge which, in case of rotation, generates an alternating pressure field migrating over the membrane. The device is particularly characterized by short response times and by a long service life due to the fact that without a substantial shearing, the filter membrane is kept free from deposits.
