Patent CA-2086289-A1 (CA)
Inventor: NODA KAZUO
IPC: G11B7/0045
Filed: 1992-12-24
Abstract: In  an  optical  information  recording  and reproducing  apparatus,  the  recording  operation  is interrupted  when  an  information  pit, dust,  scratch, stain, etc.  is present on an optical recording medium. However,  the  recording  operation  is  resumed  and  kept continued when a dust,  scratch,  stain,  etc.  other than the  information  pit  is  present  on  the  medium.    The apparatus comprises a double recording detecting circuit for detecting a pseudo double recording signal generated by a dust, scratch, stain, etc. on the medium at a period of a recording operation; and a recording signal supply circuit for interrupting the recording operation when the double  recording  detecting  circuit  detects  the  pseudo double recording signal to switch the recording period to a monitor period, for maintaining the interruption of the recording operation when a real double recording signal generated  by  an  information  pit  is  detected  at  the monitor period, and for resuming the recording operation when the real double recording signal generated by an information pit is not detected at the monitor period. After  the  recording  operation  has  been  resumed  and further when the pseudo double recording signal generated by a dust, scratch, stain, etc.  still remaining on the medium is detected, the monitor and recording periods are repeated  alternately.    However,  after  the  medium has become free from a dust, scratch, stain, etc. finally and therefore the real and pseudo double  recording signals are not both generated, the recording operation is kept continued normally.
Patent CA-2090393-A1 (CA)
Inventor: GARTNER MICHAEL L
IPC: E21B47/10
Filed: 1993-02-25
Abstract: There is described a system for determining the existence of stratified flow in the gas phase of well  fluids  produced  in  a  cased well  borehole  and flowing upwardly through a metal casing. The system includes a source of relatively low energy gamma rays, the energy thereof being chosen such that there is a small probability that a gamma ray from this source could penetrate a metal casing and be scattered back through  the  metal  casing  by  material  outside  the casing.  The system should be capable of collimating gamma rays from the source of low energy gamma rays selectively along an azimuthal direction with respect to the axis of the well casing and of generating a signal indicative of the azimuthal direction. Also provided are a scintillation detector of gamma radiation and a cooperative shielding device for preventing direct irradiation of the detector by the source while allowing the placement of the detector in close proximity to the source to allow detection of gamma rays emitted by the source and scattered by materials inside the metal casing. The system should count gamma rays detected by the detector and store count rate signals indicative  thereof.   The  count  rate  signals  are processed according to a predetermined relationship to derive  a measurement  signal  indicative  of  the  gas holdup phase of well  fluid in the vicinity of  the source.  Finally the gas holdup signal is displayed as a function  of  the  azimuthal  signal  to  provide  an indication of stratified fluid flow.

Abstract: The process of the present invention operates on the voice codewords transmitted in a digital cellular radiotele-phone environment.  The process first determines if a voice is active (201) on the communications path from the base station to the radiotelephone.  If a voice is present, a threshold is calculated (202).  Any signals on the reverse path from the radiotelephone to the base station that are below this threshold (203) are replaced by noise that is at the same level as the ambient noise (204).

Inventor: KLEEBERG HUBERTUS
IPC: A61K36/58
Filed: 1992-03-14
Abstract: Thorough efficiency studies (in relation to the azadirachtin concentration) show, that the biological activity of the active substances obtained by the methods according to the invention corresponds to that of pure azadirachtin.        The proceedures described have the advantage that only very few extraction steps and a very limited number of non-aqueous solvents are necessary and that inspite of this the oil content of the products is very low. From the residues obtained by the described proceedures the neem oil and/or other constituents of the neem kernels may easily be extracted according to known methods.        The described proceedures open the way to the simple and (economically) efficient production of a botanical, environmentally sound insecticide.

IPC: H01L23/50
Filed: 1994-02-15
Abstract: A packaged device with a lead frame, a lead frame and an article of manufacture comprising a base metal, a layer of nickel on the base metal, and a protective composite of metal layers on the nickel. The composite includes, in succession from the nickel layer, a layer of palladium or soft gold strike, a layer of palladium-nickel alloy, a layer of palladium and a layer of gold. The palladium or soft gold strike layer acts primarily as a bonding (an adhesive) layer between the Ni and Pd-Ni alloy layers and as a layer that enhances reduction in porosity of subsequent layers, Pd-Ni alloy layer acts as a trap for base metal ions, Pd layer acts as a trap for Ni ions from the Pd-Ni alloy layer, and the outer gold layer synergistically enhances the quality to the Pd layer. The various layers are in thickness sufficient to effectively accomplish each of their designated roles, depending on the processing and use conditions. Pd on soft Au strike layer may be 1-5 microinches thick, Pd-Ni alloy layer from 4 to 100 microinches, Pd layer from I to 100 micrinches and the outer gold layer from 1 to 100 microinches in thickness.

Title: Rotary locking cylinder for a safety lock
Inventor: KELLER ERNST
IPC: E05B9/04
Filed: 1994-05-25
Abstract: ABSTRACT OF THE DISCLOSURE     A rotary locking cylinder for a safety lock has a housing and a crosspiece.  A recess is incorporated in the crosspiece from the top, a locking element being inserted into this recess.  The recess connects an upper outer side of the crosspiece with a transverse bore hole in an arm of the crosspiece.  In the assembled state, the crosspiece is inserted into a recess of the cylinder pocket and connected with a transverse pin.  In order to secure the transverse pin against longitudinal displacement in the cylinder pocket, this transverse pin has a circumferential groove in which the locking element engages from above.  In order to exchange the crosspiece, the rotary locking cylinder is rotated about its longitudinal axis in such a way that the cylinder pocket is on top.  During rotation, the locking element falls downward due to the force of gravity and releases the transverse pin.  The rotary locking cylinder can be lengthened or shortened at the installation site without a reduction in strength by exchanging the crosspiece.

Inventor: BRUNELLI ROBERTO
IPC: G06T13/80
Filed: 1993-01-08
Abstract: A memory-based computer graphic animation system generates desired images and image sequences from 2-D views. The 2-D views provide sparse data from which intermediate views are generated based on a generalization and interpolation technique of the invention.  This technique is called a Hyper Basis function network and provides a smooth mapping between the given set of 2-D views and a resulting image sequence for animating a subject in a desired movement. A multilayer network provides learning of such mappings and is based on Hyper Basis Functions (HBF's). A special case of the HBFs) is the radial basis function technique used in a preferred embodiment. The invention generalization/integration technique involves establishing working axes along which different views of the subject are taken. Different points along the working axes define different positions (geometrical and/or graphical) of the subject. For each of these points, control points for defining a view of the subject are either given or calculated by interpolation/generalization of the present invention.
