Inventor: VAN BEEK G S J JANSEN
IPC: B26B23/00
Filed: 1996-07-03
Abstract: A lightweight hatchet for use by firefighters and rescue workers is disclosed.  The hatchet includes a head (11) having a blade side (15) and a cutting side (17), both designed to rip and tear an obstruction, such as a roof, wall, door, etc., without becoming entangled in the obstruction. The blade (15) includes a blade having a beveled edge (23) with a relatively sharp radius of curvature that ends at rounded corners (25). The rounded corners (25) terminate at curve-back regions (27) that curve back toward the handle (13) of the hatchet. The cutting side (17) includes a pair of teeth (31, 33), one positioned outside the other. The outside tooth (31) is curved and its periphery is beveled to create a cutting edge. The slot (35) between the teeth (31, 33) is shaped such that sheets of metal and other strong materials can be cut by inserting the outer tooth (31) in a hole in the sheet and ratcheting the handle back and forth. Both the blade and cutting sides (15, 17) of the hatchet head (11) are relatively thin. Further, the blade and cutting sides (15, 17) are of substantially the same weight to balance the hatchet.

Title: Frame relay switched data service
Inventor: HOLMGREN STEPHEN L
IPC: H04L12/56
Filed: 1998-05-14
Abstract: A new type of data transport service which uses a frame relay layer 2 data link connection identifier (DLCI) to select among various service types, feature sets, and/or closed user groups (CUGs) . A layer 3 address may be extracted from a lay er 2 frame, and the layer 3 address information may be used to route a data packet over a packet-switched network according to the service classes, feature sets, and/or CUGs selected. At the destination, the layer 3 data packet may again be enclosed in a layer 2 frame with a DLCI indicating the service classes, features sets, and/or CUGs. Because the use of conventional permanent virtual circuits (PVCs) is not required in aspects of the invention, new methods of measuring and managing network traffic are presented.

Inventor: KUBSIK ROBERT H
IPC: B65G35/00
Filed: 1998-12-03
Abstract: An apparatus and method for reducing the noise generated by colliding conveyor carriers is disclosed which comprises urethane bumpers and a method of attaching same to portions of the carriers that do not make contact with other carriers when the carriers are accumulated. The bumpers extend from the carriers a sufficient distance to contact a similar bumper on an adjacent carrier when one carrier rolls up against another. The bumpers do not prevent the normally contacting portions of the carriers from coming into contact, but merely absorb a portion of the kinetic energy of the moving carrier to reduce the noise generated when the contacting portions of the trolleys do meet, and the presence of these bumpers does not adversely affect the spacing of the carriers in the accumulation line.

Filed: 1999-04-19
Abstract: The bracket is to be installed to the inner face of the peripheral rim of a bathtub, to attach the latter to the inner peripheral edge portion of a fixed casing.  The bracket has a rigid head portion which is fixedly attached to the inner rim of the bathtub, and a downwardly depending arcuate resilient foot which carries at its lower end a foot. When installing the bathtub inside the casing and more particularly inside the casing peripheral edge portion, the tub is downwardly displaced until its rim comes into downward abutment against the casing peripheral edge portion, the bracket slidingly abutting against the casing peripheral edge portion with a corresponding resilient foot deformation, allowing the foot to slide under the casing peripheral edge portion and to snap itself thereunder for preventing vertical displacement of the bathtub relative to the casing peripheral edge portion. Indeed, the casing peripheral edge portion is then wedged between the bracket foot and the bathtub rim.
