Title: Tape storing and feeding mechanism for mailing machines
Inventor: BUCKLEY FRANKLIN J
IPC: G07B17/00
Filed: 1999-05-05
Abstract: A high speed, high volume mailing machine which utilizes ink jet technology for the printing of postage indicia on envelopes being fed through the mailing machine and on discrete portions of tape fed past the printing device of the mailing machine includes a tape storing and feeding mechanism which stores a roll of tape in the form of a web of indefinite length for feeding a discrete portion of the tape past the feeding device for each printing operation of the mailing machine, and feeds the tape forward to bring the printed portion thereof past and then reverses the movement of the tape to bring the new leading edge thereof to the beginning of the printing area. The tape storing and feeding mechanism provides a fixed support for the portion of the tape being printed on so as to maintain a critical gap between the surface of the tape and the plane of the jet nozzles to achieve a high printing quality. The tape storing and feeding mechanism also provides a feeding device which maintains effective control over the movement of the tape without contacting any part of the printed portion thereof, and further provides ample shock absorbing for the roll of tape so that sudden acceleration of the tape strip does not tear the tape in the printing area.

Inventor: ACS GABRIEL
IPC: B65D23/10
Filed: 1999-08-23
Abstract: A soft drink bottle holder for attachment to a soft drink large diameter bottle compromise: a top snap ring, a hand grip element distant from annular surface of the bottle with an integrated finger stopper supported by a web with a rib and a loose fitted body supporting ring. The holder is "slide-on" type, so lifting the bottle for putting the holder on the bottle is unnecessary. A finger stopper on a hand grip element of the bottle allowing use of a person's thumb giving the leverage for manipulating and pouring the liquid from the bottle. For the convenience of packaging and storing, the holder could be made of two pieces from thermoplastic; material. In this case the holder, before it usage, would need some simple assembly. A soft drink bottle holder is designed, so it will fit brand name and common design bottles.

Patent CA-2287625-A1 (CA)
Title: Method of patching downhole casing
Inventor: VLOEDMAN JACK
IPC: E21B29/10
Filed: 1999-10-22
Abstract: A method for lining a portion of a casing affixed within a well bore a distance below an upper end of the well bore with a viscoelastic pipe having an upper end, a lower end, and an outer diameter greater than the inner diameter of the casing is provided.        The outer diameter of the pipe is reduced so that the outer diameter of the pipe is less than the inner diameter of the casing.        The reduced pipe is then lowered into the casing to a predetermined depth where the upper end of the reduced pipe is positioned a distance below the upper end of the well bore. The reduced pipe is then allowed to expand against the internal wall of the casing, thereby forming a fluid tight seal with the casing and effectively sealing any breaches in the casing. So that the outer diameter of the reduced pipe remains less than the inner diameter of the casing as the viscoelastic pipe is being passed down the casing, the reduced pipe is maintained in tension as the reduced pipe is being passed down the casing. Tension is maintained on the reduced pipe by suspending an amount of weight from the lower end of the pipe prior to passing the pipe down the casing. The amount of weight is sufficient to maintain the pipe in tension as it is being passed down the casing so that the outer diameter of the pipe remains less than the inner diameter of the casing as the pipe is being passed down the casing.

Title: A coding/modulation scheme selection technique
Inventor: BUDKA KENNETH C
IPC: H04W28/18
Filed: 2000-01-14
Abstract: In a wireless data network, such as a General Packet Radio Service (GPRS) network, a transmitter uses one of k coding/modulation schemes for transmitting data. The transmitter initially selects a coding/modulation scheme, C, as a function of carrier-to-interference ratio (C/I) measurements. The transmitter then calculates the number of blocks, B, required to transmit a number of data packets, D, using the coding/modulation scheme C. In addition, the transmitter calculates the number of blocks required to transmit the number of data packets, D, for each coding/modulation scheme that is stronger than the selected coding/modulation scheme C. The transmitter finally selects that coding/modulation scheme that results in transmitting the number of data packets D in B blocks using the strongest coding/modulation scheme. As a result, each block is transmitted using the strongest coding/modulation scheme available.
