Patent CA-2097443-A1 (CA)
Inventor: HAAB KARL
IPC: E01B11/32
Filed: 1993-06-01
Abstract: Two mutually adjoining profile pieces (1a) of equal cross-section are connected by means of a coupling piece (16) which overlaps both of them and is situated in a coupling groove (15). The convexly arched floor of the latter is formed by the underside of a crossbar (5), the top side of which forms a running surface (6) for bearing rollers of running mechanisms. In the downward. direction, the coupling groove (15) is limited by lateral holding strips (18a,b) exhibiting flat, inwardly inclined holding surfaces (19a,b), which point towards the floor of the said coupling groove and against which are pressed corresponding contact strips (20a,b) of the coupling piece (16), which coupling piece is braced against the holding strips (18a,b) of each of the profile pieces (1a), by meaner of, in each case, two tapping screws (17b) pressing against the floor of the coupling groove (15).      At the bottom, the coupling groove (15) is adjoined by a guide groove (9) for receiving guide rollers.      For the purpose of enabling a particularly stable connection of the profile pieces - for example in the case of a rail supported only punctually by means of sliding blocks, which are disposed in a fastening groove and in which threaded bolts engage - the profile pieces can be provided with two coupling grooves disposed at a distance apart one above the other.

IPC: G06M7/06
Filed: 1994-01-11
Abstract: A sheet counter system having feeding section,  carrying section; counting section and stacking section, has a control section such that in the case where the length of a sheet or the like is less than a length reference value, the control section starts braking of the feeding section when the front end of an n-th sheet (n is a predetermined set value)  which has been fed out is detected by the counting section, while in the case where the length of said sheet is greater than the length reference value, the control section starts braking of the feeding section when a carrying distance after the front end of the n-th sheet which has been fed out is detected by the counting section reaches a predetermined distance to thereby stop feeding by the feeding section when the counted result of the counting section reaches a predetermined number of sheets. In order to improve counting accuracy, controlling can be performed by taking feeding speed into consideration.

Inventor: WALTER DAVID T
IPC: F16D55/32
Filed: 1993-02-11
Abstract: A brake device (10) has a housing of which the two parts (11,15) are releasably connected together by bolts (25). Co-operating pressure fluid passages in the two housing parts communicate pressure fluid from a source to actuators within the housing, and include separable plug and socket connectors (30, 31) located on the respective housing parts so that separation of the parts effects disconnection of the actuators from the pressure fluid source. A non-return valve is arranged to close on separation of the housing parts and to be opened again by the plug connector. An electrical connection to an electrically powered cooling fan can be similarly broken when the housing parts are separated.

IPC: B60R21/26
Filed: 1994-10-19
Abstract: An apparatus (10) for inflating an air bag includes a container (12) for holding a stored supply of gas under pressure.  A body (20) of gas generating material is disposed in a housing (22).  A cup shaped closure member (24) blocks a flow of gas through an annular array of passages (28) formed in an end wall (58) of the container (12).  The cup shaped closure member (24) has a frangible section (176).  Upon ignition of the body (20) of gas generating material, the gas applies pressure against an end wall (166) of the closure member (24) to break the frangible section (176) of the closure member.  The pressure applied by the gas against the end wall (166) of the cup shaped closure member (24) moves the closure member toward an opposite end of the container (12).  Gas flows from the container (12) through the openings (28) in the end wall of the container into a diffuser (36).  The diffuser (36), closure member (24) and housing (22) which holds the body (20) of gas generating material are all connected to the end wall (58) of the container (12).

Filed: 1994-07-11
Abstract: A system and method are disclosed for controlling a shift even in a transmission (14) wherein a shift actuator (30,48) develops a force to effect the engagement of a clutch collar and a gear. The method comprises detecting when a non-fully engaged condition of the clutch collar and the gear occurs, indicating either a tooth butt or torque lock condition, and then pulsing the shift actuator (30,48), when the non-fully engaged condition is detected, between a relatively low force and a relatively high force to disturb the clutch collar and the gear out of the non-fully engaged condition, The detecting step comprises examining either the axial position of the clutch collar or the axial position of a shift rail operatively connected to the clutch collar with a rail position sensor (43). Preferably, a signal having a modulated pulse width and a frequency of between about 5 and 20 Hertz is sent to the shift actuator. The system which embodies this method is disclosed in the forms of an automated mechanical transmission having sliding clutch collars (122,124,126) and a transmission system having a standard friction master clutch interposed between the engine and the transmission.
