Abstract: Beads of molten glass fall successively into a scoop channel (8) which supplies one after another with beads a number of channel systems (3) e.g. of an I.S. glass making machine and which is pivotable about a vertical axis. The bead moves along a movement path (13) from the scoop channel (8) in free flight onto a sliding body (9), from this in free flight into a long channel (10) and from this again in free flight into an end channel (11) which is curved downwards. The end channel (11) delivers the bead in such a manner that its longitudinal axis runs coaxially with the longitudinal axis (31) of a mould (4) to be charged. The sliding body (9) is supported rigidly on the machine. The long channel (10) is supported with its upper end (18) on the sliding body (9) via a universal joint (38). The lower end (23) of the long channel (10) is guided in a vertical shaft (42) of the end channel (11) and can be raised and lowered by an adjusting device (43). <IMAGE>

Inventor: HOGAN PATRICK J
IPC: F02B61/04
Filed: 1993-07-09
Abstract: ABSTRACT OF THE DISCLOSURE      A method of coupling steering movement of two outboard motors is described.  Firstly, mount a first end of a flexible push-pull control cable to a boat adjacent a primary outboard motor.  The first end has a protruding first push-pull rod. Secondly, mount a second end of the flexible push-pull control cable to the boat adjacent an auxiliary outboard motor.  The second end has a protruding second push-pull rod.  Thirdly, connect the first push-pull rod to the primary outboard motor. The first push-pull rod moves inwardly and outwardly relative to the first end of the flexible push-pull control cable with the motion of the primary outboard motor thereby resulting in an equal and opposite movement of the second push-pull rod which is coupled with the first push-pull rod through a flexible interior cable extending through the flexible push-pull control cable.  Fourthly, connect the second push-pull rod to the auxiliary outboard motor.   As the second push pull rod moves inwardly and outwardly relative to the second end of the flexible push-pull cable the auxiliary outboard motor is moved as a slave to the primary outboard motor.

Title: Apparatus for reducing magnetic field-induced bias errors in a fiber optic gyroscope
Inventor: HUANG SIDNEY X
IPC: G02B6/00
Filed: 1993-09-07
Abstract: ABSTRACT         Apparatus for suppressing the bias errors induced by the Faraday effect in the output of a sensor coil exposed to a magnetic field.  Arrangements are formed at two leads of the sensor coil for compensating the bias shifts.  One of such arrangements comprises at least one loop of optical fiber for compensating the effect induced by the magnetic field component oriented transverse to the axis of the sensor coil while the other comprises at least one loop oriented at a predetermined pitch angle for compensating the effect induced by a magnetic field component along the axis.  In each case, a predetermined degree of twist of a preselected fiber twist mode is imposed upon the compensator loop for creating a counteracting, corrective Faraday effect.   Cross-coupling does not occur between the two compensators as their twist rate perodicities are unequal.

Title: A bale, an apparatus and a method for the wrapping of a bale in two crossing wrapping layers applied in overlapping helical turns
Inventor: SOEDERBERG STAFFAN
IPC: B65B41/16
Filed: 1992-04-08
Abstract: A method for packaging bales with strips of plastic packaging film, in which a bale is rotated about a generally horizontal axis and, when appropriate, about a generally vertical axis, and wherein film is taken from a film magazine spaced from the bale and wrapped around the bale in successive turns while maintaining the film under tension, and wherein the film in each turn of film around the bale extends generally parallel with and transversely to the horizontal axis. The method is mainly characterized in that the bale is then wrapped with a further wrapping of film, and in that successive turns of this further wrapping cross-over those parts of the turns of the underlying film which extend generally parallel with the horizontal axis, in a manner to retain the underlying turns. This film material is held under tension while being applied. The invention also relates to an arrangement for carrying out the method, and to a bale.

Title: Steering bearing assembly for a bicycle
Inventor: CHIANG DOUGLAS
IPC: B62K21/06
Filed: 1994-01-14
Abstract: A steering bearing assembly includes a head tube, a steerer tube that has a first end which is connected to a front fork of a bicycle and which extends through the head tube, and a bearing assembly disposed between the head tube and the steerer tube.  A truncated cone-shaped inserter is disposed in  a second end of the steerer tube and has an axially extending threaded bore formed therethrough.

Title: Human cancer inhibitory pentapeptide amides
Inventor: PETTIT GEORGE R
IPC: C07K5/02
Filed: 1994-01-19
Abstract: ABSTRACT        The synthesis of useful peptides presents a promising approach to new therapeutic agents. The Dolastatins, a series of linear and cyclic antineoplastic and/or cytostatic peptides isolated from Indian Ocean sea hare Dolabella auricularia represent excellent leads for synthetic modification.        In the present invention, the corresponding amine was allowed to react with Boc-L-phenylalanine.    Synthesis of amides led to excellent yields; The protecting group of amides was removed with hydrogen chloride in acetic acid to afford the hydrochloride salt, The correspondent deprotected N-tert-butyloxycarbonyl-L-phenylalanineamide was coupled with dolaproine in the presence of diethyl phosphorocyanidate and triethylamine thereby yielding dipeptideamides. The protecting groups of amides was removed with trifluoroacetic acid to afford the trifluoroacetate salt. Diethyl phosphorocyanidate was used again with excellent results for coupling tripeptide trifluoroacetate with each of the amide salts to yield Dolastatin 10 structural modifications.        The extraordinary inhibition of cell growth shown by the pentapeptideamides against six major types of human cancer has been presented. The intermediates of these reaction also show anticancer activity against the murine P388 lymphocytic leukemia cell line.

Filed: 1992-07-29
Abstract: A method for assaying for the presence of analyze in a sample based on differential binding affinity involves detecting dissociation of a complex of receptor and ligand in the presence of analyte, The receptor binds the analyte with high affinity and with the ligand with low affinity. The receptor-ligand complex may be formed in situ or may be preformed. In the presence of free analyte, the receptor releases from the receptor-ligand complex and binds free analyte. Release of the receptor-ligand complex is detectable. A kit for performing release assays to detect the presence of analyte is also provided.

Filed: 1994-02-08
Abstract: On encoding with a smallest possible number of bits LPC parameters produced by an LPC analyzer (19) from at least one of subframe signals of each frame signal of an input speech signal, a divider (21) divides the LPC parameters into several parameter regions.  Using vector code books (25(1m), 25(2m)) loaded for each parameter region with code vectors, a vector quantizer (23) quantizes the LPC parameters into, for use as quantized codes, indexes of selected vectors which are selected from the code vectors and of which a linear combination minimizes a quantization distortion.
Patent CA-2116990-A1 (CA)
Title: Robotic Gripper Mechanism
Inventor: SCHAUER FRANK
IPC: B25J15/10
Filed: 1994-03-04
Abstract: A robotic gripper module, which can be fitted to a robotic arm or other support means, houses a rotor which is rotatable relative to the frame of the module. The rotor has at least two equiangularly positioned slots, each extending at the same relative angle to a radius of the rotor. A cam follower mounted on radially-moveable slide members is positioned in each of those slots and also in a respective radial slot in the module frame, and rotation of the rotor causes the cam followers and slide members, on which finger assemblies may be mounted, to move together radially inwardly or outwardly on the frame. An arcuate gear segment on the periphery of the rotor meshes with a gear rack on one end of a rod; the other end of the rod connects to a piston-and-cylinder actuator. In one form of the module two rotors rotate on a single axle, one on each side of the module. The two rods associated with the two rotors extend from opposite sides of the cylindrical space between the rotors, and the pair of associated actuators are positioned outside that space. This arrangement allows for a thin module with a significant space saving over other robotic modules.
