Abstract: An apparatus for applying decalcomania to a curved  surface of  a  container  is  provided.    The apparatus includes a base, first and second curved rigid support members pivotally connected with respect to each other, a band mounted to the end portion of each support member, a heater assembly supported within the band, and a handle linkage adapted to open and close the support members with respect to each other.   Movement of the handle linkage causes one support member to close with respect to the other support member, thereby tightening the band and heater assembly about a container for application of the decalcomania.   A turn-buckle type adjustment is provided for adjusting pressure applied by the handle linkage.

Title: Anti-vibration adaptor
Inventor: BARNES GEORGE EDWARD
IPC: B25B23/00
Filed: 1994-12-29
Granted: 2005-03-22
Abstract: An anti-vibration adaptor having a wear resistant, vibration absorbing sleeve which mounts over the conventional releasable connection between a socket wrench and drive wrench. The adaptor substantially reduces run-out which is typical to conventional relatively loose mating socket connections and which are prone to excessive vibration and losses in torque. Consequently, the adaptor substantially increases torque imparted to a fastener and significantly decreases vibration experienced by an operator, thereby improving the quality of the driven fasteners and decreasing the chance of operator injury.

Granted: 2004-02-17
Abstract: In a method and apparatus for making two-component fibers, a polymer (B) which is supplied laterally with respect to a further polymer (A) and a die (12), is at first distributed inside cross-channels (23) provided in a pre-die (14), and then being redirected, through holes (16), in the extruding direction. The channels (23) operate to re-arrange the polymeric mass with the new distribution above the die, so as to eliminate possible discontinuities of the values of the chemical-physical parameters of this mass and which are due to the direction variation the mass is subjected to as it is switched from the side channels (20, 22) to the cross channels (23). Thus, a constant value of the mentioned parameters through the polymer mass being supplied to the extruder is assured.

Title: Synchronization of communication devices connected over an asynchronous link
Inventor: WOOD ROBERT
IPC: H04L12/70
Filed: 1997-03-11
Granted: 2004-01-27
Abstract: In a method of establishing communication between synchronous devices over an asynchronous communications channel, each device samples a signal to be transmitted at a rate determined by a local clock. The rate of transmission of samples over the channel is determined by the local clock in each device. At least one of the devices is periodically adjusted to match the rates of transmission and arrival of samples over the channel, for example, by adjusting the frequency of the local clock or by dropping or duplicating samples. With this arrangement there is no need to exchange explicit timing information.

Abstract: When switching to a forward running is made while a vehicle is running in a reverse direction, a switching to the forward running condition is made at an early time to thereby prevent the deterioration of the durability of the hydraulic engaging element due to slipping. For that purpose, when a vehicle speed (V) has exceeded a predetermined value (YVa) in a reverse range (R) and also when the vehicle speed (V) has never fallen below the predetermined value (YVa) in a neutral range (N), a reverse signal (FREV = 1) is outputted. If FREV = 1 at the time of switching to the forward range, the relationship between the vehicle speed and the speed stage (speed change map) is set to one (a reverse-running-measure speed change map) which is different from that at an ordinary time, to thereby determine the speed stage to be established. Then, a low speed stage is established even at a relatively high vehicle speed. Switching is thus made at an early time to the forward running condition with a large torque to be transmitted via the low speed stage. By using a sensor that can detect the, actual direction of running of the vehicle whether it is in the forward direction or reverse direction, the reverse-running-measure speed change map is selected as the speed change map when the direction of running of the vehicle to be detected in the forward range is in the reverse direction.
Patent CA-2221217-C (CA)
Inventor: ALLPRESS STEPHEN ALAN
IPC: G06F17/14
Filed: 1997-11-17
Granted: 2001-10-30
Abstract: Polyphase channelizing transmitters convert multiple signal channels into a single stream for transmission and corresponding polyphase channelizing receivers process the received stream to recover signals corresponding to the original signal channels. The filter transfer functions for both the transmitters and receivers are designed to have non-recursive numerators and recursive denominators. Such filters can be realized using non-recursive (e.g., finite impulse response (FIR)) filters and recursive (e.g., infinite impulse response) filters on opposite sides of a Fourier transform. For a given application, polyphase structures of the present invention may require fewer coefficients to implement than conventional (e.g., FIR-based) solutions and will therefore be less complex and less expensive.

Title: Analog-to-digital transition: selecting the optimal cellular radio mix
Inventor: BENVENISTE MATHILDE
IPC: H04W16/06
Filed: 1998-04-08
Granted: 2002-07-09
Abstract: In a transition phase of a cellular cell from analog-to-digital radio service it must be determined how many of the base station radios in a cell must be changed over from analog to digital, given the proportion of mobile phones with dual-mode capability to analog phones. A dual-mode mobile phone has the capability to interface with both analog and digital radios. In determining the radio mix, it is desirable to maximize the call handling capacity of a cell, or minimize the blocking experienced by the mobile subscribers. To address these questions, an analytical model is developed to compute the blocking rate experienced by mobilecallers in a cell, given the cell's offered load, the mix of analog and dual-mode mobiles, and the analog-digital split of the RF channels available to the cell. The model's results enable selection of the channel split that gives the lowest blocking rate, and to compile charts that show the relationship between the proportion ofdual-mode mobiles, the number of digital radios in a cell, and the maximum offered load that can be served at a specified blocking rate.
