Patent EP-0263532-A2 (EP)
Inventor: GUERTIN RAYMOND J
IPC: B24B47/04
Filed: 1983-08-26
Abstract: A surface grinding machine (10) capable of being computer operated and having a multi-function capability for performing conventional slot and surface, plunge, side wheel, creep feed and short stroke grinding in any desired combination or sequence. A table (18) containing a workpiece (90) is driven by a highly tensioned, circulating primary belt drive system (50) capable of providing a desired grind with a desired length and speed upon command. The base (12) is preferably formed as a unitary body, and the table (18) travels on ways (20) which are formed integrally with the base (12). The column (14) containing the grinding wheel (40) moves with respect to the workpiece (90) along cross ways (16) transverse to the table ways (20) which are supported along their length by the base (12). The column drive (100) is coupled to the column (14) by a mechanically and thermally isolated ball screw nut mount (118, 120, 122 and 124) which eliminates screw nut shoulder weave and reduces thermal   conduction into the column (14). A housing (22) containing the grinding wheel (40) assembly moves vertically along ways (24) in the column (14) and a magnetic brake (156) is utilised in the vertical drive (154) for the wheel housing (22) to prevent damage to the workpiece (90) during power interruption. Both the vertical ways (24) for the wheel housing (22) and the horizontal cross ways (16) for the column (14) are self-aligning. A computer terminal (26 and 258) may be provided for automatic control of the machine, and a manual control panel (28) may also be provided, which is slidable across the front of the machine (10) for convenience of oepration thereof.

Abstract: A pulse train divider circuit comprises a first flip-flop (1) whose Q output is connected to the D input of a second flip-flop (2) whose Q output is connected to the D input of the first flip-flop (1). A pulse train to be divided is applied via an input (3) directly to the clock input C of the first flip-flop (1) and via a circuit (4) which delays the pulse train applied to the clock input C of the flip-flop (2) to provide a given phase relationship between the pulse trains at the two clock inputs. The circuit divides-by-two and the resulting divided pulse trains available at the various outputs have phase relationships depending on the phase relationship of the applied pulse trains at the clock inputs.

Abstract: The pile-to-ground warp yarn ratio of terry cloth is controlled during the weaving operation by sensing both the tension imposed on the pile warp and the amount of pile warp yarn dispensed from the supply beam (12). The sensed information is used to control the speed of a pile warp let-off motor (24) which dispenses the pile warp yarn from its beam. Additionally, the sensed information is employed to selectively alter the displacement of a rocking bar (18) to vary the height of the terry loop formed in the cloth.

Abstract: A method of recognizing (distinguishing) a radiation field is provided for radiation image recording and reproducing systems that utilize stimulable phosphor sheets. With respect to the process of reproducing radiation image information stored on the phosphor sheet by scanning it with stimulating rays, such as laser light, the present method allows the radiation field on the sheet to be precisely distinguished, reducing the influence of undesirable stored image energy emissions from outside the prescribed region. This enables radiation images to be obtained that are more effective for diagnostic purposes. The method can also be applied for the recognition of irregularly shaped radiation fields, which hitherto has been extremely difficult.

Abstract: The pump comprises a pump body (1) and a volute, mutually complementary with respect to one another, which once assembled form a waterproof container within which a permanent magnet rotor (5) and an impeller (4) are contained respectively in a first (2) and in a second chamber. The stator part of the electric motor is provided externally to said waterproof container, and thus can never be affected by the liquid. The introduced improvements relate to the coupling between impeller and rotor and to the means adapted to make the rotor chamber waterproof, so that there cannot enter therein foreign matter, and in particular metallic dust, which by remaining associated with the permanent magnet of the rotor would prevent the rotation thereof, blocking its operation.

Abstract: A reduced redundancy error correction and detection code is shown for memory organized with several bits of the data word on each chip. This package error correction and detection will correct all errors on any one chip and detect errors on more than one chip. A certain arrangement of an ECC matrix is first created for a symbol size code greater than the number of bits per chip. Thereafter certain columns of the matrix are removed to create the final code having a symbol size the same as the number of bits per chip. A specific example of an 80 bit code word is shown having 66 data bits and 14 check bits for a 4-bit-per-chip memory.

Abstract: In a method for the thermal treatment of wastes, in particular of special wastes, the waste is conveyed to a combustion chamber and combusted giving rise to slag, waste gas and flying dust, the flying dust conducted out with the waste gas being separated off subsequently. In order that considerably smaller quantities of flying dust contaminated with heavy metals arise and the possibility is afforded of recovering the heavy metals, the flying dust is divided into a fine dust fraction and only the coarse dust fraction is conducted back and bound into the liquid slag with evaporation of the adherent volatile harmful substances, while the harmful substances adherent to the fine dust fraction are recovered.

Abstract: The invention proposes a pneumatic shock absorber with a piston (10) displaceable in a cylinder (11) and having a piston rod (14) which projects from the latter. Via a non-return valve (25) which forms an inlet, a pressure space (12) situated in the cylinder (11) and bounded by the piston (10) is connected to an external pressure source (P). An outlet valve (19) which releases the compressed air during a damping movement of the piston has a valve piston (41) which is guided in a sealed manner in a valve chamber (29) and divides the latter into two sub-chambers (32, 33). The first sub-chamber (32) connects a passage (20) leading to the pressure space (12) to an outlet passage (35), the connection being interruptable by means of a valve seat which can be closed by an end face of the valve piston (41) subjected at least in part to the pressure of the pressure space (12). The second sub-chamber (33) is connected to the pressure space (12) or to the pressure source (P). Finally, a spring (39) which presses the valve piston (41) against the valve seat (36) is provided. As a result, no pressure losses occur in either of the two stop positions, the piston returns automatically to the first stop position in the unloaded condition and the damping performance during the damping process is very uniform and continuous. <IMAGE>

Abstract: There is disclosed a signal scrambling transmission system in which the data (34) is scrambled at the transmit end by logically combining (20) the data with a pseudo random sequence (38) generated by a ROM (18) prior to transmission. The data is recovered at the receive end by logically combining the scrambled data with the same pseudo random sequence generated by a ROM. The ROM at the transmit end is divided into frames with a synchronization word and a frame count (index) word imbedded in each frame. The synchronization word and index word are transmitted with each frame of data and are used to synchronize the ROM at the receive end with the incoming scrambled data. The transmit end ROM (18) is divided into 32 frames each being 4,096 bits long. Each frame has a 27-bit synchronization word, a 5-bit index word, and 4,064 bits of pseudo random sequence.

This enables the surface potential to be precisely controlled without necessiting a frequent calibration of the surface potential detecting device (7). In addition, the potential of the reference potential measure section (6) is appropriately set depending on a developing condition so as to prevent toner (from  being fixed thereonto), when the reference portion passes at a developing unit (10).
