Title: Tea filter pack for automatic brewers
Inventor: GRUENBACHER DANA PAUL
IPC: B65D81/00
Filed: 1994-05-16
Abstract: A conformable, self-aligning, high extraction efficiency tea filter pack (1) capable of flavor extraction efficiencies comparable to those obtained using an identical quantity of bulk tea leaves and a paper filter  under identical brewing conditions, but which exhibits substantially consistent pot-to-pot brew strength for any given automatic drip coffee maker. The preferred filter pack is formed from two layers (10, 20) of flexible material which are secured to one another about their outermost periphery with a predetermined quantity of tea leaves (50) housed within a brew chamber (40) formed between the two layers (10, 20). The brew chamber (40) exhibits a maximum volume between about 100 percent and about 400 percent greater than the volume of the dry tea leaves contained therein. The discharge flow rate (F3) from the brew chamber is slower than the inlet flow rate (F1) into the brew chamber to permit a buildup of water and flooding of the brew chamber (40). The flexible conformable side wall surrounding the brew chamber (40) extends upwardly a vertical distance which is at least sufficient to capture enough hot water to totally immerse the brew chamber (40) when the brew chamber (40) is in its fully expanded condition. This causes the tea leaves (50) within the chamber (40) to expand and float throughout the remaining portions of the brew cycle, thereby establishing a steady state brewing condition which is highly effective in maximizing tea/water contact as the hot water passes through the brew chamber (40) on its way to the pot.

Patent CA-2170417-A1 (CA)
Inventor: IKI NAOHIRO
IPC: H04Q3/54
Filed: 1991-03-28
Abstract: In a reconfigurable communications system, circuit status bits are stored in a first matrix of rows associated respectively with predefined network configurations and columns associated respectively with predefined circuit configurations. Destination status codes are stored in a second matrix of rows associated respectively with the circuit configurations and columns associated respectively with switching nodes of the system. Each circuit configuration comprises one or more transmission links and each circuit status bit stored in each column of the first matrix pattern indicates the presence or absence of the circuit configuration associated with that column. Each destination status code indicates the presence or absence of transmission links from each switching node to possible destination nodes. In response to a manual command, the circuit status bits stored in one of the rows of the first matrix are respectively multiplied with the destination status codes stored in each column of the second matrix, and the multiplied binary values are summed so that network configuration data is derived with respect to a desired network configuration, which is then transmitted to the switching nodes to reconfigure the system. A difference is detected between the network configuration data successively derived with respect to previous and most recent network configurations, and transmitted as network configuration signals to those switching nodes requiring reconfiguration.

IPC: E21B10/38
Filed: 1997-02-26
Abstract: A percussion drill bit includes a drill body having a fluid passage formed therein for conducting flushing fluid to a front drilling face of the drill bit.      The fluid passage includes a main portion extending from a rear end of the bit and terminating short of the drilling face, and a plurality of branch lines extending from a front end of the main portion to the drilling face. Front and rear axially spaced seats are disposed in the main portion of the fluid passage. A check valve in the form of a ball is freely movable within the main portion of the fluid passage between contact with the front and rear seats. When the drill bit is oriented upwardly and no flushing fluid is supplied, the ball gravitates rearwardly into sealing contact with the rear seat so that no fluid can flow rearwardly past the rear seat. When flushing fluid is conducted, the flushing fluid pushes the ball forwardly, into non-sealing contact with the front seat and travels past the ball into the branch lines. During downwards drilling, if the density of the ball is less than that of backflowing fluid, the ball will float upwardly upon the back-flowing fluid and into sealing contact with the rear seat.
