Patent CA-2207314-A1 (CA)
Title: Cam operated timer
Inventor: BURGIN HENRY EARL
IPC: H01H43/10
Filed: 1997-05-28
Abstract: An appliance timer has features to facilitate automated assembly or manual assembly. A timer housing base accepts timer components from two directions, and installation of components in either direction is along a straight axis. A motor in the timer engages a gear train which runs a drive cam. The drive cam imparts motion to a camstack which then engages timer blade switches, and the blade switches operate the appliance. A subinterval is also supplied on the timer to allow periodic operation of a switch without the use of the camstack. The timer also features a quiet manual advance which removes the blade switches from communication with the camstack to allow an operator to select various timer programs without any of the clicking noises that are usually associated with timer program selection. Furthermore, a detent slider is positioned in communication with the camstack to provide a tactile feel for the operator of the timer when selecting between various timer programs.

Filed: 1996-01-23
Abstract: A network computer system providing for the fault tolerant storage and retrieval of data files includes a client system connected to a data communication network that may source a first data transfer request to said data communication network for the transfer or retrieval of data. A first server system, including first medium for storing data files, is connected to the data communication network so as to be responsive to first data transfer requests.  A second server system, including second medium for storing data files is also connected to said data communication network to also be responsive to first data transfer requests. A control protocol, established between the first and second server systems, coordinates an asymmetric response by the first and second server systems to a first data transfer request, such that file data transferred by the client with the first data transfer request is replicated to the first and second storing mediums and such that file data transferred to the client system in response to the first data transfer is non-replicatively provided to the client system by either the first or second server system.

Title: Cutting inserts for a side milling cutter and a side milling cutter comprising such cutting inserts
Inventor: ROMAN STEFAN
IPC: B23C5/20
Filed: 1998-04-08
Abstract: A cutting insert for milling cutter tools, primarily for side milling cutters and slotting cutters, has upper and lower, mutually opposed surfaces (17,18), of which at least the lower one (17) is substantially planar in order to form a bottom surface that may bear against a cooperating support surface on the milling cutter tool. Further, the cutting insert comprises mutually opposed first and second side surfaces (20) and mutually opposed third and fourth side or gable surfaces (30,31), which either forms a main cutting edge (23,25) at an edge line distal from the bottom surface (17). The cutting insert may be rotated half a revolution in order to indexate the one and the other main cutting edge, respectively. One of the main cutting edges (25) is more distant than the other main cutting edge (23) from the center axis of the screw hole, the more distant cutting edge being shorter than the nearer cutting edge (23) and located substantially symmetrically relative to the middle of said side or gable surface (30) in this way, when the cutting inserts are mounted into alternate directions in the side milling cutter, a chip partition is obtained, and thereby an improved chip-flow.

Title: Low torque threaded fastener and mine roof support system using such a fastener
Inventor: TREMBLAY RICHARD
IPC: E21D21/00
Filed: 1998-06-10
Abstract: A mine roof support system which includes a steel anchor rod and a threaded fastener.  The rod has a threaded end portion, and which is adapted for positioning in a bore hole so that the threaded end portion projects outwardly from a rock face.  The threaded fastener includes a body having a pair of opposing end portions and a bore which extends  along  its  central  axis.     Internal  threads complimentary to those on the rod are formed along part of the axial length of the bore, whereby the relative rotation of the fastener and rod moves the rod axially through the bore.   A cap member is detachably coupled to one end portion of the fastener covering part of the bore.  When coupled,  the cap member acts as a positive stop which limits relative movement of the rod axially through the fastener bore, and which when detached allows the fastener to run freely along the threaded portion of the rod.

Abstract: The invention relates to a device for measuring the surface hardness of rolls (2) of paper or other material. Said device comprises at least one hardness measuring head (12) with at least one rotatably mounted contact roll to rest, under radial pressure, on the revolving roll (2) of paper or the like. The hardness measuring head (12) can be moved on a rail (11) substantially parallel to the winding axis of the roll (2) or the like and has means for evaluating the measuring signals of the hardness measuring head (12). It is proposed to provide first and second means to monitor and, optionally, influence parameters of a material strip wound to form the roll, such as roll hardness, strip tension, uniformity of roll diameter along the roll width and the like, during winding. Said means can be used to hold at least one of the contact rolls (126, 127; 126', 126'', 127'') in position on the roll (2) with a first force and to cause at least one of the contact rolls (126, 127; 127', 127'') to penetrate with a second force deeper into the surface than with the first force.
