Title: Eyeglasses catch
Inventor: MRAVINSKY IGOR
IPC: G02C3/04
Filed: 1996-10-31
Abstract: My invention relates to the eyeglasses protection device of that class which is employed for safeguarding the eyeglasses from damage, loss and forgetfulness of the owner. The object of the invention is to provide an eyeglasses protective device of this kind that shall be very light, strong, inconspicuous, easily attached and which prevents any accidental drop and damage. Another object of the invention is to provide a device that may be cheaply manufactured from a variety of different material (see specification) and which can be of colour of different shades to match the garments. With these and other objects in view, my invention relates to a novel construction that will hereinafter be fully described and claimed and illustrated in the accompanying drawing which forms a part hereof and in which like figures of reference refer to corresponding parts in all of the views, and it is understood that slight changes may be made without departing from the spirit of the invention. The idea is the result of a search for a solution to a notorious problem of frequent eyeglasses' loss and annoyance when attempting to find them but as "ill luck would have it they cannot be found anywhere...'' Such situations occur very often as a result of simple human forgetfulness and absentmindedness. A simple device that I invented does not allow the owner to leave the glasses unattended and provide the security from falling down and prevents them from damage and destruction. In contrast to the existing device called the ~EYEGLASSES' STRING'', the ~EYEGLASSES' CATCH~ provides a possibility to hold the eyeglasses tucked away in a pocket, they do not become a hindrance during any motion, especially when bending, neither becoming a personal safety hazard during any activity. Besides, such a device can be almost invisible and as a result not to interfere with whole dress arrangements. The main purpose of the ~Eyeglasses' Catch'' is that the owner not only never drops or damages the eyeglasses, he never forgets them. In our times when eyeglasses are very expensive item, this simple and cheap device can be a very good protective tool against damage and loss and to be a solution against frustration related to someone's forgetfulness and at the same time spare the owner from cumbersomeness and unwieldyness of having the eyeglasses sitting on the chest. On top of that, the device may not upset any dress arrangements and can be very inconspicuous if the wearer that desires. Thus, such a device rules out the eyeglasses' accidental plunging down and whereby their destruction, and also preventing them of being lost or being routinely searched for.

Title: Injection molding manifolds with melt connector bushing
Inventor: GELLERT JOBST ULRICH
IPC: B29C45/27
Filed: 1996-07-05
Abstract: Multi-cavity injection molding apparatus having two heated manifolds interconnected by a connector bushing all extending in a common plane. A threaded portion of the connector bushing is screwed into a threaded opening in one manifold and a nonthreaded portion of the connector bushing is received in a nonthreaded opening in the other manifold.          The nonthreaded portion of the connector bushing fits in the nonthreaded hole in the other manifold tightly enough to prevent melt  leakage,  but  is  still  able to  slide sufficiently  in  the  opening  to  accommodate  thermal expansion and contraction of the heated nozzles relative to the cooled mold in which they are mounted and located. In one embodiment, the connector bushing is made of a material such  as  a  beryllium  copper  alloy  having  a  greater coefficient of expansion than the steel manifolds so it can be easily installed and then expand to produce this fit when heated to the operating temperature.

Patent CA-2187189-A1 (CA)
Inventor: RUPPEL JOHN STEPHEN
IPC: H04W36/00
Filed: 1995-12-21
Abstract: A method for improved frequency assignment includes recording handoff statistics for subscriber units handing into and out of a base station (130). The handoff statistics include the IDs of the other base stations (240) involved in the handoff, along with the date and time of the handoff.     The statistics of the handoff count are applied based on the number of occurrences within a time period (450), and are used to accept or reject the potential frequency assignments obtained from an assignment algorithm. In one embodiment of this algorithm, using a Q estimate, obtained from residual powers recorded on each frequency (435), a candidate frequency is chosen based on the lowest Q value. This candidate is tested against the handoff statistics, and if rejected, a frequency with the next lowest Q level is tested.     This process is repeated until a frequency is assigned.

Title: Electron generating apparatus, image forming apparatus, and method of manufacturing and adjusting the same
Inventor: FUJII AKIRA
IPC: G09G3/22
Filed: 1996-11-01
Abstract: It is an object of this invention to provide an electron generating apparatus which is hardly influenced by variations in driving voltage, an image forming apparatus using the electron generating apparatus, and a method of manufacturing and adjusting the same.  The row wiring layers of a multi-electron-beam source (300) are sequentially selectively switched by a control circuit (302) and applied with a pulse voltage having a value about 1.05 to 1.5 times the maximum value of a normal driving voltage from a DC voltage source (301).  The characteristics of all surface conduction electron-emitting devices of the multi-electron-beam source (300) are shifted to the high potential side.  With this process, even when the driving voltage becomes high due to superposition of noise and the driving voltage, variations in electron-emitting characteristics caused by the voltage shift characteristics of the surface conduction electron-emitting devices can be prevented.

Title: Block decision feedback equalizer
Inventor: CROZIER STEWART N
IPC: H04L25/03
Filed: 1997-01-28
Abstract: A block decision feedback equalizer uses a Cholesky algorithm to factora channel impulse response correlation matrix in order to solve for data received over a dispersive communications channel. While the Cholesky algorithm increases the computational complexity of the initial data symbol estimate (the result of a linear block estimation), its use allows the use of a recursive update for computing successive data symbols with little additional computation. Further, the Cholesky algorithm is free of limitations that would limit detection to cases where the channel span or memory is smaller than the probe segment following the data block to be detected. Additional functions such as diversity combining, incorporation of a time-varying channel response model and fractional baud-period sampling are provided in the block detector.

Filed: 1995-08-10
Abstract: A controlled deflection roll (1) has a rod shell (2) which is hydrostatically radially supported by internally disposed hydrostatic shoes. In order to axially position the roll shell (2) a mechanical location link (23) is provided which is disposed externally of the roll shell (2). The link is coupled at one end to an element attached to the roll shell (2), and is coupled at an opposite end to a fixed support, such as a floor stand (7). The end of the roll at which the locating link (23) is disposed is thus axially fixed, while the opposite end of the roll remains free to float. The locating link (23) can be connected to an oscillator to oscillate the roll shell (2) axially during operation so as to distribute any non-uniformities in the roll shell (2) and thus to mitigate their effect on the sheet.

Inventor: BEREZA WILLIAM
IPC: H03L7/08
Filed: 1997-04-23
Abstract: A charge pump circuit includes a current mirror circuit of current-sourcing and current-sinking FETs and a current steering circuit of cross coupled differential pairs of FETs. Nominal current flowing in the current-sourcing and current-sinking FETs is set. The current is for charging and discharging a capacitor of an external filter. During charging of the capacitor, the current through the current-sourcing FET is directed to the capacitor and the current through the current-sinking FET is directed from a low impedance voltage source. During discharging of the filter capacitor, the current through the current-sourcing FET is directed to the low impedance voltage source and the current through the current-sinking FET is directed from the capacitor. The current flowing in the current-sourcing and current-sinking FETs is nominally constant, regardless of the tri-state condition, charging or discharging, with the result that noise is reduced. Current change in the power supply rails is reduced when switching from current-sourcing to current-sinking or vice versa. By using cascode FETs in both of the current-sourcing and current-sinking FET circuits, power supply noise rejection is improved.

Title: Process for the production of tocopherol and tocopherol/tocotrienol concentrates
Inventor: WILLIAMS HAMPTON LOYD CHIP III
IPC: C07D311/72
Filed: 1995-11-07
Abstract: Disclosed is an improved process for the preparation of tocopherol and tocopherol/tocotrienol concentrates from vegetable oil distillates. Tocopherol concentrates are obtained containing 20-80 % tocopherol by weight, with an overall recovery of tocopherol of 72 % to 97 %. The process is comprised first of an esterification reaction where the more volatile alcohols are converted to their less volatile fatty acid esters, followed by a series of distillation steps where components boiling higher and lower than the tocopherols are separated from tocopherols and other like boiling substances. Advantages of the process are that tocopherol and tocopherol/tocotrienol concentrates are produced efficiently and economically in a minimum number of steps without the use of solvents and with a relatively small capital investment.

Abstract: A hole  (30)  is drilled in a turbine blade  (10)  by laser drilling.    The  turbine  blade  (10)  comprises  a  superalloy substrate  (12),  a bond coating  (14)  and a ceramic thermal barrier coating (16).   The hole (30)  is produced by firstly focusing the laser beam (26)  such that the focal point  (28) is on the surface of the ceramic thermal barrier coating (16) to drill a small diameter hole (18)  through the turbine blade (10).   The laser beam (26)  is refocused such that the focal point (28)  is spaced from the surface of the ceramic thermal barrier coating (16).   The laser beam (26)  is pulsed on and off to drill a large diameter hole  (30)  coaxially with the small  diameter hole  (18).    The  small  diameter  hole  (18) allows the molten material and heat to be expelled from the hole  ( 18)  and reduces heating of the  superalloy substrate (12)  to reduce the thickness of the oxide layer and recast layer around the hole and prevent delamination of the ceramic thermal barrier coating (16).
