Abstract: This device for actuating a tip-up or sectional door comprises an elongated frame structure supporting a linearly movable member driven through a worm screw or a chain connected to the door to be driven, and secured at two upper points of which one is located at one end of the frame structure. This one end is secured to a fixed support formed with a vertical notch of which the bottom edge has a groove formed therein, the upper edge of this notch being limited by a surface located at a predetermined distance from the groove bottom. The frame structure comprises a support surface, for example in the form of a pin, and a locking surface, for example in the form of another pin, located at a distance from the first pin which corresponds to the predetermined distance. This frame structure can be fitted by a single person by anchoring the lower pin of the support and then raising the frame structure to a substantially horizontal position, so as to lock automatically the device in its operative position.

Abstract: In a water driven down-the-hole rock drill, the rearward end of an associated hammer is provided with a drive piston reciprocable in a cylinder located adjacent the rear of the drill. The front end of the hammer is guided for reciprocation in a bearing located adjacent an anvil of a drill bit. Between the cylinder and the bearing the hammer is elongated and enlarged diametrically relative to the piston. The enlarged hammer portion reciprocates freely in a chamber formed by an outer casing of the drill. Drive water is expelled from the cylinder and flushes the hole drilled by the bit. An open ended tubular valve reciprocates to control a duct connecting the interior of the valve to coaxial through-flushing channels in the hammer and the drill bit.

IPC: H04N1/387
Filed: 1991-12-30
Granted: 1996-06-25
Abstract: A signal processing system includes means for performing a logic function on a multi-dimensional array of information stored in a memory. Typically, the memory stores two-dimensional video information (pixels), and the logic function is a discrete cosine transform (DCT), or other linear operation. The logic function is performed on both rows and columns of the information. In the prior art, this has required two memory spaces, so that information could be written into one memory while being read out of another memory. In the present invention, a single memory space is used to transpose the information between row and column format,by performing a read-modify-write operation on each memory location in a specified sequence.
