Inventor: SHIKAMA TOSHIHIRO
IPC: H04L47/52
Filed: 1994-08-09
Abstract: ABSTRACT OF THE DISCLOSURE    This invention provides a frame relay apparatus and a relay method with an efficient transfer time, regardless of the transmitting rates of the input signal and the output signal.  A route control table which corresponds the transmitting line number to the transmitting logical link number by using the receiving line number and the received logical link number of the header of the received frame is provided as is a line attribute table which stores the transmitting rates of the input signal and output signal.  Furthermore, the line attribute table to store the transmitting rates of the input signal and the output signal and a comparison control mechanism to calculate the necessary buffering amount of the sending buffer based on the frame length of the concerning received frame which is gotten at or before the receiving time of the data of the received frame are provided.  Additionally, a transmitting handler mechanism is provided to start a transmission immediately when the transmission rate of the designated transmitting line is equal to or lower than the transmitting rate of the input signal, and to start a transmission after storing the transmission data up to the required buffering amount when the transmitting rate of the input signal is higher than the transmitting rate of the output signal.

Title: Pivot bearing for a chop saw
Inventor: GARUGLIERI ANDREA
IPC: B27B5/20
Filed: 1994-08-10
Abstract: ABSTRACT OF THE DISCLOSURE PIVOT BEARING FOR A CHOP SAW    A saw (10) has a saw assembly (20) pivoted about pivot axis (28) to a pivot member (26).  The pivot member is pivoted to a pivot block (27) about a bevel axis (92).  The pivot block is fixed to a table (16) in a frame (12).  Pivoting of the pivot member about axis (92) permits bevel cuts to be made in workpieces (now shown) supported on the table (16) against fence (17) when the assembly (20)  (which includes a motor driven blade (36)) is pivoted down about the axis.   Between the pivot block and pivot member is disposed a bearing plate (46)  which serves several functions.  It reduces friction and wear between the pivot block and member and the need for machining of those parts.  It serves to hold resiliently the bevel pivot axis bearing surfaces (88, 90, 130, 132) in position.  It provides index notches (61) to locate the bevel position of the pivot member relative to the pivot block.  It provides a rack 50 for a bevel position indicating pinion (52) to engage.

Patent CA-2139268-A1 (CA)
Inventor: KAKU TOMOYA
IPC: H04J13/00
Filed: 1994-12-29
Abstract: In a sync acquisition and tracking circuit for a DS/CDMA receiver, phase position signals are sequentially and cyclically selected at a specified rate higher than the rate at which Rayleigh fading occurs. The selected signal is used to control the phase of PN sequences. Correlation is taken between spread pilot signals and the orthogonal PN sequences at a chip rate to produce despread pilot signals, which are integrated to produce a correlation value. A set of accumulators are provided, which are sequentially and cyclically selected at the specified rate. The correlation value is applied to the selected accumulator to produce a total sum of correlation values. The highest total sums are selected from the outputs of all accumulators, and corresponding phase position signals are identified. A set of orthogonal despreading sequences are generated corresponding to the identified phase position signals for application to the receiver.

Patent CA-2157068-A1 (CA)
Inventor: ALDERMESHIAN HRAIR
IPC: H04M3/54
Filed: 1995-08-28
Abstract: One communications device (called the "impersonating" device) can selectively impersonate another communications device (called the "impersonated" device) by arranging the impersonating device to take over and/or use the same network identification number (typically stored in an identification number memory and used to control selection of incoming calls to which the device responds) normally associated with the impersonated device. As a result of impersonation, there is a hand-off between the devices, with the impersonated device becoming dormant and the impersonatingdevice becoming active, such that calls normally received by the impersonated device are received by the impersonating device, and such that calls originating in theimpersonating device get the identical network treatment as would be accorded to calls originated by the impersonated device, all of this without any need to adjust or update profiles stored in a network database. Impersonation can be triggered automatically, as by the physical proximity of one terminal device to the other, or manually, such as by pushing a button on one of the devices.

Title: Vertical vaporizer for halide-free, silicon-containing compounds
Inventor: WILLIAMS RICHARD REED
IPC: C03B8/04
Filed: 1995-12-06
Abstract: A vaporizer for halide-free, silicon-containing liquid reactants used in producing preforms is provided. The vaporizer includes a heated, vertically-oriented expansion chamber (20) and a vertical hollow shaft (42) which extends into the chamber and has a plurality of orifices (45) at its upper end (44). Preheated reactant is supplied to the vertical shaft (42) at an elevated pressure and is sprayed onto the chamber's heated wall (22) by the orifices (45).  A portion of the liquid reactant vaporizes upon entering the internal volume (24) of the chamber (20) due to the pressure drop between the inside of the shaft and the inside of the chamber.  The remainder of the liquid reactant vaporizes by being heated through contact with the chamber's wall (22).  Higher molecular weight species present in the raw material or generated by the vaporization process are collected in the bottom portion of the chamber where they can be periodically removed.

Abstract: An improved footed cooking utensil is provided whereby the cooking utensil may be removed from a hot oven and placed directly on a counter-top or other surface without the need for a hot pad, cutting board, or similar device. The cooking utensil of the present invention includes foot supports which suspend the lower surface of the cooking utensil above the counter-top thereby eliminating contact between the counter-top and hot metal. The low heat capacity footings do not retain heat and any heat absorbed during the baking process is quickly dissipated upon removal of the utensil from the oven. One or more footings may be applied to metal cookware, ceramic cookware or cookware fabricated from other materials.
