Patent CA-2035955-A1 (CA)
Inventor: STARK IVAN L
IPC: E05C17/64
Filed: 1991-02-07
Abstract: A sash balance apparatus for vertically slidable window installations, in which a friction shoe is disposed in a channel formed by a jamb liner extending along each side of the slidable sash and a connecting member extends between the sash and the friction shoe in a manner such that the weight of the sash when applied to the shoe tends to pivot the latter at least slightly within the jamb liner channel and thereby bring predetermined surfaces of the shoe into frictional contact with corresponding surfaces of the jamb liner channel, preferably including elongated rib-like intermediate walls which extend into the channel from its sides.  The channel thus provides a plurality of different longitudinally-extending friction surfaces which may be selectably engaged by the friction shoe as a function of its particular configuration, dimensions, and the degree of tilt introduced by the applied weight of the sash.  In a preferred form, the connector extending between the sash and the shoe comprises a rigid member disposed at an acute angle with respect to the shoe and its channel to promote tilting, and in the most preferred form the connector comprises a particularly bent section of metal wire or rod which is press-fitted or otherwise frictionally attached to the shoe.          Also, the jamb liner has laterally offset tab portions which provide integral stops for limiting allowable vertical travel of the shoe.

Title: Protective device for temporary system overvoltages
Inventor: TAHILIANI VASU H
IPC: H02H9/04
Filed: 1991-04-10
Abstract: ABSTRACT        An apparatus and method for a power overvoltage protection system for limiting sudden transition line overvoltages. the apparatus and method include a voltage divider having a first varistor block and a second varistor block electrically connected in series.    The first block and the second block each having a plurality of varistors. The first block  exists in a non conductive mode during normal operation of the power system.   A thyristor circuit having a voltage sensor and a pair of oppositely coupled thyristors, is electrically connected between the first and second blocks and ground.  The voltage sensor continuously senses line voltage Vo, and a trigger mechanism continu-ously compares the sensed voltage Vo with a predetermined critical voltage of magnitude Vp to form a ratio. When the voltage Vo exceeds a predetermined threshold value of approximately 1.1 or 1.2 PU, the thyristor is activated into a conductive mode so that the line voltage Vo is entirely absorbed by the first block of the remaining voltage Vo through the oppositely coupled thyristor pair to ground.  The thyristor is reset into non-conductive mode when the Vo/Vp ratio falls below the predetermined value.            A-43490/AJT/JAS                 June 15, 1990

Filed: 1991-04-11
Abstract: ABSTRACT "Modular Blasting System"     Modular components including donor units, relay units, and detonator units create a variety of blasting systems.  A donor unit is formed from a signal transmission tube having donor mini-caps attached to each end thereof.  A relay unit is a device having a receptacle at one end to receive a donor mini-cap in operative association and engaging means to operatively engage a point along another donor unit such that the detonator contained within the relay unit will initiate the transmission lines passing through the donor unit. A detonator unit is provided for the initiation of explosives such as boosters and primers and comprises a shell for receiving explosives and a receptacle at one end suitable for receiving a donor mini-cap at the other end. Relay units allow for the simultaneous initiation of several donor units.  Each donor unit can be attached to either additional relay units or to detonator units.  Detonators can instantaneously explode or be fitted with delay elements.  Thus, complex detonation patterns can be constructed with relatively few, easily assembled modular components.

Inventor: HOLM FRANK P
IPC: B25B13/12
Filed: 1992-07-21
Abstract: In an adjustable box wrench for gripping hexagonal nuts and bolt heads, the wrench consists of three movable parts. The first part consists of a hexagonally shaped head, open top and bottom, permanently attached to a hollow tubular shaft which is attached to a handle.  The extremity of the head has two gripping surfaces at 120° to one another, forming the fixed jaw of the wrench.  The second part is a movable jaw with simi-lar oppositely placed gripping surfaces permanently attached to a rod which passes through the tubular shaft and is threaded on the end where it leaves the tubular shaft and enters the handle. The third movable part is a knurled adjustment nut which is restricted in its forward and backward movement but which engages the threaded end of the rod and thus can advance and retract the movable jaw.  The invention places the adjustment screw in the handle instead of in the head of the wrench, thus reducing the bulkiness in the head while also allowing the user to operate the wrench with one hand.  The adjustment nut can be manipulated by the thumb and forefinger while firmly gripping the handle with the rest of the hand.  Since the parallel lateral surfaces of the movable jaw are slidably confined by the two parallel inner surfaces of the sides of the head, the jaws of the wrench can be extended downward to engage a hexagonal nut or bolt head which is recessed.
