Abstract: ABSTRACT      An array of overlapped, interlocking horizontal cladding panels is secured to a wall by parallel vertical stringers having vertically spaced resilient clips for holding the top margins of the panels.   The top margins of the panels and stringer clips cooperatively provide a double locking arrangement such that as a panel is mounted on the stringers, it is moved into a first position in which its top margin engages clips of the stringers and then is moved upwardly into a second position in which it simultaneously further engages the clips and interlocks with the next lower panel in the array.   To this end, the top margin of each panel has a locking projection above the conventional lip provided for interlocking with the bottom margin of the adjacent higher panel, and each clip has two vertically spaced locking surfaces for successively engaging this locking projection as the panel top margin is pushed upwardly undr the clip.   In some embodiments, each panel also has a central flange projecting inwardly and upwardly for engagement with retaining tabs formed in the stringers.

Abstract: WELL SLIP UNIT          Abstract of the Disclosure A slip unit for releasably supporting a well pipe, including a support structure to be positioned on and turn with a rotary table and preferably taking the form of a slip bowl, and a vertically movable slip carrier structure suspending a number of pipe-gripping slips and adapted to be releasably retained by latch means in a lower active position, with the carrier and slips being yieldingly urged upwardly to inactive positions when the latch means are  released.  The support structure and carrier structure are both desirably formed of complementary sections hinged for relative swinging movement between closed positions about the pipe and open positions permitting movement of the unit laterally relative to the pipe, and with an additional latch being provided for retaining the structures in their closed positions.  The carrier structure and slips are urged upwardly by spring cartridges which are removable as units from the slip assembly in a condition maintaining the actuating springs under compression and preventing injury or damage by release of the spring force during removal.  Vertical guides are provided circularly between the slips for centering a well pipe in a manner preventing damage to the slips by engagement with enlargements on the pipe.

Abstract: ABSTRACT OF THE DISCLOSURE        A fixed contact element and a movable contact element can be brought into and out of engagement with each other within a switching chamber.  The switching chamber communicates, on the one hand, by means of a blast nozzle closed by the movable contact element in the "on" position of the gas-blast switch, with an expansion chamber and, on the other hand, communicates by means of a check or a non-return valve which opens in the direction of the switching chamber, with a pressure chamber of a pump cylinder arranged in the expansion chamber.          Operatively associated with the pump cylinder is a movable pump piston which pressurizes the pump cylinder during a cut-off stroke with a time-delay.  To reduce the structural expenditure and to increase operational reliability, the pump piston is rigidly connected with the movable contact element, while the length of the pump cylinder is less than the switching stroke of the movable contact element, so that the pump piston is located externally of the pump cylinder at the region of the cut-on position of the gas-blast switch.

Abstract: ABSTRACT A method  of fabricating a series-connected combination of two-terminal semiconductor devices on a common substrate in which active areas for the devices are provided by the deposition of a layer of high quality semiconductor on the surface of a temporary substrate.  A first region of contact pattern conductors is formed on the free surface of the high quality semiconductor layer to provide a separate first contact to this layer, an insulating support substrate is bonded to the first contact pattern and the temporary substrate is removed to provide a second free surface of the high quality layer.  A second region of contact pattern conductors is formed on the second free surface of the high quality semiconductor to provide a separate second contact to this layer for each of the devices.  Active areas for the devices are defined by removal of regions of the high quality layer at any stage after beginning the formation of the first contact pattern so that parts of the first contact pattern are exposed when both the temporary substrate and such regions of the high quality layer have been removed.  Series connection of the devices is then achieved by interconnecting the exposed parts of the first contact pattern with the appropriate parts of the second contact pattern.

Abstract: (59-13 C.I.P.) ABSTRACT           A device for tensioning the endless drive belt for vehicle accessories.  A housing is mounted in a fixed position adjacent the drive belt. A shaft assembly is slidably mounted in an axial bore formed in the housing and includes a stub shaft portion extending outwardly from the housing through a slot formed in one of the housing walls.  An idler pulley is rotat-ably mounted on the stub shaft and is moved into tensioning engagement with the drive belt by a compression coil spring which is adjustably mounted in the housing bore by a spring guide.  The spring slidably moves the shaft assembly in a belt tensioning direction within the housing bore.  Concavely curved surfaces are formed in certain areas of the shaft assembly within the housing.  Roller means are interposed between and are biased by a spring into a wedging relationship within curved shaft surfaces and adjacent housing walls.  The roller means permits free movement of the shaft assembly and idler pulley in the belt tensioning direction while preventing move-ment of the shaft assembly in the opposite nontensioning direc-tion because of the wedging acting of the roller means. In another embodiment the shaft is operatively connected to a pivotally mounted, vehicle accessory whereupon sliding movement of the shaft pivots the accessory to tension the drive belt which is engaged with the accessory pulley.
