Title: Snow vehicle
Inventor: PERTILE LIANO
IPC: B62M27/02
Filed: 1994-09-14
Abstract: ABSTRACT      A snow vehicle comprises at least one runner (20, 20'; 54) by way of a ski which is mounted in such a way that it can be  tilted and/or steered by means of manual tilting and/or steering members (5) connected actively to actuators (17, 18, 22, 17', 18', 22'; 153) for tilting and/or steering the runner (20, 20'; 54). In order to ensure greater ease, accuracy and reliability of steering, the invention provides that  the  manual  tilting  and/or  steering  Member  (5)  is connected  to  the  runner  (20,  20',  54)  tilting  and/or steering actuator (17, 18, 22, 17', 18', 22'; 153) by means of a transmission system (30, 26, 27, 126, 127, 26', 27', 126',  127';  60,  61,  60', 65, 66, 67, 67') constructed in such a way as to be mechanically rigid, i.e. with little or no play relative to the position of tilting and/or steering. The vehicle may be of the so-called snowmobile kind, or else a vehicle with no means of propulsion and adapted only to descent,  similar to a skibob. The invention also includes further improvements to the structure of the frame of a snow vehicle.

Title: Spring mounted tracklaying tractor chassis
Inventor: URBANEK HENRICH
IPC: B62D11/10
Filed: 1993-04-06
Abstract: When using a self-supporting wheel tractor body to build a tracklaying tractor, it is necessary to supplement the body of the tractor with a massive frame for spring mounting the running wheels.  This frame has the disadvantage of considerably increasing the weight of the tractor and of making access to the tractor body difficult. It is proposed that the journal (49) of a tensioning wheel (50) carries a double-armed balance beam (51) whose lower arm (52) is mounted on a main arm (2) of the chassis and whose upper arm (53) is rotatively linked to a tension jack (54) arranged on the main arm (2). The running wheels (67, 68, 69, 70) are secured to the main arm (2) by means of rockers (3, 59) with primary springs (4) inserted between the rockers (3, 59) and the main arm (2).  A secondary spring (5) is supported from above on the main arm (2) and secured to a console (6) arranged on the body (82) of the tractor. The axis of a drive wheel (7) is downwardly and backwardly oriented with respect to the axis of a countershaft (8) of the portalgear (9), and the axis of the countershaft (8) is downwardly and backwardly oriented with respect to the axis of a ring gear (10) of the bevel gear.

Title: Temperature-resistant and/or nonwetting coatings of cured, silicon-containing polymers
Inventor: BLUM YIGAL D
IPC: C08L83/16
Filed: 1993-11-18
Abstract: Surfaces of various types of substrates, including glass, ceramics, metals and fabrics, are rendered thermally stable by treatment with a silicon-containing polymer which may be a polysilazane, a polysiloxane, or a polysiloxazane.

Patent CA-2156190-A1 (CA)
Inventor: WILLIS KENNETH E
IPC: F42C19/12
Filed: 1994-02-23
Abstract: This invention discloses a method of fabricating an electroexplosive, device which utilizes a semiconductor bridge (292) as an ignition element. The semiconductor bridge (292) is electrically connected to a metal header (100) by a small, low resistance contact to the extension of bridge material and through an insulating silicon substrate (270) to a eutectic bond (260) created by gold plating (350) on the metal header (100) and the silicon. The second electrode (360) of the bridge circuit is connected via wire bonds (130) to one or two conducting pins (110) which penetrate the metal header (100) and are insulated by surrounding glass (120). The design allows the use of standard semiconductor assembly methods. Since small pads of electrical material are used for electrical contact, the die size is small. A redundant connection via two conducting pins (110) insulated from the header (100) to one electrode (360) of the semiconductor bridge allows a post assembly test of the integrity of the wire bonds.

Abstract: In a telecommunications call a different charge is incurred for intervals of noncommunication than for intervals during which communication may take place. For example, a period of hold is one during which the party on hold cannot communicate with the other end of a connection. Such intervals are accumulated for a call and the charge for the call is adjusted in accordance with the total length of the noncommunicating intervals. Advantageously customers ate charged primarily for the period of time during which they can actually communicate, without having todisconnect and later reestablish a call.
