Title: Bore mapping and surface time measurement system
Inventor: NOTTINGHAM LAWRENCE D
IPC: G01N29/04
Filed: 1987-06-16
Granted: 1992-06-23
Abstract: 53,449 ABSTRACT OF THE DISCLOSURE            The present invention includes a bore mapping system that includes one or more high resolution ultrasonic mapping transducers that are used to measure the diameter of a bore. The travel time for a normally incident pulse to reach the bore surface and return for each transducer is used with a reference reflection time measured diameter from a mechanically measured reference diameter using a known velocity of the ultrasonic pulse in an immersion fluid.  The diameter measured by each of the transducers is averaged to obtain an average measured diameter which is produced for plural axial rotor positions.  The present invention also includes a surface time measurement system that uses at least one ranging transducer measuring the ranging time required for a ranging beam to reach and return from the bore surface.  The measured ranging time is used with a calibrated ranging time obtained in the calibration bore to modify a calibrated inspection beam surface time for an inspection transducer to obtain a current inspection beam surface time.  The ranging time can also be used to obtain a correction time curve that provides correction time for the inspection beam surface time versus circumferential bore position.  The calibrated inspection beam surface time or the correction time curve, are used to correct positions of flaws in the rotor material.

Title: Assembly of tightly adjacent eye needles
Inventor: BERGER JOHANN
IPC: D04B27/24
Filed: 1987-06-29
Granted: 1991-10-01
Abstract: ABSTRACT         The invention concerns an assembly of sets of lightly adjacent eye needles (12) for filling-yarn knitting machinery.  One set each of eye needles (12 is anchored by injection molding in supports (8,9) at mutually equidistant positions, the needles being mutually parallel by their main planes.  Two supports (8,9) each with a set of eye needles (12) form one segment of eye needles.  The heads (22) of the eye needles (12) of the first set (24) of needles alternatingly enter centrally between every two heads of the eye needles of the second set (25) of needles. The two sets of needles are fixed within the segments and are oblique in such a manner that a conceptual plane from one of the sets(24) of needles (plane (5) of the set) extending along the eye needles and through the heads of this set of needles intersects the plane (5') of the set of the other needle-set (25) in the region  of the heads.  As a result, very fine ribbons or tapes may be manufactured that require minute separations between the heads of the eye needles, while eye needles having comparatively thick stems nevertheless can be used and these stems furthermore can be anchored by injection-molding them in each support.  A segment of eye needles also can be formed by more than two mutually oblique sets (24,26, 26) of needles.

Title: Apparatus for use in plant growth promotion and flower development
Inventor: LONGSTAFF ERIC
IPC: A01G13/02
Filed: 1987-10-14
Granted: 1992-11-10
Abstract: ABSTRACT OF DISCLOSURE            Method and apparatus for encouraging maximal  plant growth which method and apparatus comprise a light filter which prevents the natural decay of plant growth stimulating materials by absorption of UV radiation while permitting photosynthesis to occur with blue light in the absence of attendant heat generating and dehydrating radi-ations caused by green, yellow and infra-red light.  The objective is made possible according to the preferred embodiment of the invention by interposing separately, continuously, or discontinuously, a com-bination of filters made of solid material between the sun and the growing plants which block out radiation in those wave lengths which are either physiologically harmful or which retard growth, but do not inhibit those wavelengths which are necessary for photosynthesis, metabolism, differentiation and development.

Title: Child resistant closure with deformable panel
Inventor: WILSON WOODROW S
IPC: B65D47/08
Filed: 1988-04-28
Granted: 1991-03-26
Abstract: ABSTRACT         A child resistant dispensing closure characterized by a closure member and a lid member which is mounted on the closure member for movement between closed and open positions.  A peripheral edge of the lid member abuts an annular shoulder provided on the closure member in the closed position, the point of abutment being concealed by an annular ring provided on the closure member.  In the closed position, thickened portions provided on the peripheral edge of the lid member engage in recesses formed in the annular shoulder.  The lid member is adapted to be moved upwardly from the closed to an open position when a user applies with one hand a manual compressive force to a panel provided on the exterior skirt of the closure member.  This manual force results in deformation of the panel inwardly into a slot formed clearly through an enlarged portion of the shoulder.  As a result, a slight separation occurs between the peripheral edge of the lid member and the shoulder so as to allow the user, with the other hand and while continuing to compress the panel, to engage the peripheral edge of the lid member for moving the lid member to the open position.

Title: Method for generating a correction signal in a digital clock recovery device
Inventor: SARKOEZI IMRE
IPC: H04L25/40
Filed: 1988-10-25
Granted: 1991-11-19
Abstract: Abstract Disclosed is a method for generating a correction signal in a digital clock recovery device.  A digital clock recovery system according to a prior proposal contains in a phase sensor a delay device.  This cannot be implemented with the required accuracy in integrated circuit technology.  It is therefore intended to develop a method which does not need any delay device for its implementation.  In this method, the phase sensor does not compare the phase relationship of the active edges of the pulses of a digital signal with a first auxiliary data clock which acts as clock recovered from the digital signal.  Instead, the phase sensor compares the phase relationship of the active edges of the pulses of the digital signal and of a second auxiliary data clock which exhibits a defined phase difference with respect to the first auxiliary data clock.  If the comparison does not result in a phase difference, a correction signal is generated which causes a phase correction of both auxiliary data clocks producing the defined phase difference.  Digital clock recovery devices are used in digital signal multiplexing devices and distributor multiplexors between, in particular, higher levels of a digital signal hierarchy.

Title: Ball bearing retainer for drawer slides
Inventor: BAXTER ALAN R
IPC: F16C29/04

Granted: 1992-08-11
Abstract: ABSTRACT         A unique ball-bearing retainer is disclosed for use with two or three part drawer slides for filing cabinets and the like.  The retainer uses a standard channel member with upturned side flanges.  The flanges are equipped with round apertures and then bent at the approximate mid-point thereby creating an elliptical aperture providing a seat for rotation of a common steel ball.  The ball comes in contact with the aperture at the base and the top of the same such that during operation of the drawer slide the portions of the ball having maximum rotation or movement do not contact the retainer thereby reducing friction, and increasing the life of the drawer slide.
