Title: Candy dispenser having an increasable storage space/adaptable size
Inventor: HUBERT PAUL
IPC: G07F11/44
Filed: 1993-03-30
Abstract: ABSTRACT OF THE DISCLOSURE:      The  candy  dispenser  comprises  a  dispenser  housing having  an  upper  candy  compartment  and  a  lower money compartment  separated  from  one  another  by  a  forwardly declining partition wall.  The candy compartment has a rear upper  surface  provided  with  a  candy  inlet  adapted  to accommodate a mouth of an upside down candy jar with a shoulder of the jar resting on the upper surface.  The candy compartment also has a projecting first front portion in front of the candy inlet, the first front portion being provided with an upper candy access opening.   The money compartment has a money access opening and also a second front portion extending beyond the first front portion of the candy compartment.  The second front portion has a money slot on an upper surface thereof.  The dispenser housing is provided with a front flap for closing the candy access opening, and a lid for covering the candy inlet.  The lid is movable between a first position where the candy jar is positionable upside down with its shoulder in abutment on the upper surface and its mouth inserted in the candy inlet, and a second position where the candy inlet is closed by the lid.  The storage space of the candy dispenser is therefore increasable  by  appending  the  candy  jar  to  the  candy compartment.

Title: Method for the automatic insertion or removal of a calling number identification (cnid) blocking prefix from within a telephone number in a personal computer based telephone management system
Inventor: DETERING GREIG R
IPC: H04M1/27485
Filed: 1993-12-03
Abstract: With Calling Number Identification (CNID) service, Frequency Shift Keying (FSK) data is sent over the tele-phone lines to the telephone service customer. A tele-phone subscriber may prevent their name/number from being transmitted to the party they are calling on a per call basis by dialing a prefix before they dial the desired number. The present invention allows for the automatic insertion/removal of that prefix in the number stream when the called party's number is dialed. This feature is accomplished by inserting a $ character into the dial-ing sequence. If the blocking feature is enabled, the $ is translated to the numeric sequence necessary to pre-vent the transmittal of one's telephone number. In the alternative, the $ is translated to a meaningless delim-iter if the feature is disabled.
Patent CA-2116029-A1 (CA)
Title: Code Server
Inventor: PICKETT STEPHEN F B
IPC: G06F9/445
Filed: 1992-08-21
Abstract: A code server operates in a data processing system having an operating system or environment, such as OS/2 or Windows, which processes coded programs in discrete code modules. The code server maintains linkage information between the various code modules forming an association representing all the linkage data for the entire program. This information is gathered by way of searching through the files of the computer network or by direct insertion into the code module information table. Once the associative data has been gathered, a coded program may be retrieved quickly and efficiently without the need for repetitive on-line searching because the user need refer only to the code server which contains a look-up tables storing the data representing the. associative information.

Patent CA-2127151-A1 (CA)
Title: Spatially scalable video encoding and decoding
Inventor: PURI ATUL
IPC: H04N7/50
Filed: 1994-06-30
Abstract: SPATIALLY SCALABLE VIDEO ENCODING AND DECODING            Abstract of the Disclosure Video images of varying resolutions are derived from one video signal with high bandwidth efficiency, in accordance with the principles of the invention, by employing a new two-layer video coding technique using spatial scalability in which the prediction taken from one layer is combined with the prediction taken from the other layer, and the combined prediction is used to code one of the layers. In an illustrative example of the invention employing a base-layer and an enhancement-layer, the spatially interpolated base-layer is combined, by the selection of appropriate weights, with the motioncompensated temporal prediction of the enhancement layer to generate the prediction used to encode the enhancement-layer. Weights are selected based on a calculation of the sum of the absolute differences, or the sum of the squares of the differences between the prediction and reference macroblocks to produce the prediction giving the best bandwidth efficiency. This weighting process is called spatio-temporal weighting. (FIG. I )

Inventor: NISHIBORI SADAO
IPC: B29C48/07
Filed: 1994-11-07
Abstract: A synthetic wood meal in which a thermoplastic resin material of 25 to 80 wt% is mixed with a cellulose crushed material of 20 to 75 wt% that lies in the moisture content of within 15 wt% and the mean particle diameter of 20 mesh or less, the mixed material is kneaded so as to be set to gel, and the kneaded material is cooled and pulverized and regulated to a size that lies in a particle diameter of 10 mm or less.

Filed: 1995-04-20
Abstract: A method of regulating backpressure traffic in a packet switched network made up of a plurality of switching elements each having a local buffer memory identifies at least one switching element which succeeds at least one other switching element in a transmission path. The at least one succeeding switching element has a congested local buffer memory. A backpressure signal is transmitted to the at least one other switching element. Packets destined for the succeedingswitching element are queued in the local buffer memory of the at least one other switching element. Next, it is determined when the occupancy of the local buffermemory for the other switching element has exceeded a predetermined threshold. In response to the exceeded predetermined threshold, the other switching element ignores the backpressure signal transmitted from the succeeding switching element and transmits the queued packets to the succeeding switching element.
