Patent GB-488568-A (GB)
Title: Improvements in processes for roasting nickel matter
IPC: C22B23/02
Filed: 1937-01-08
Abstract: In roasting nickel matte in a rotary kiln, the unroasted matte is mixed with roasted matte to lower the sulphur content, say to about 8 per cent, so as to reduce the risk of partial melting. Roasting is effected at a temperature of about 1000 DEG  C. in the presence of a substantial excess of oxygen.  The roasted matte may be heated to 1100-1300 DEG  C. to remove residual sulphur, the heating being effected in the presence of only a small excess of oxygen.  The two stages may be effected in a single rotary kiln, the material to be roasted and the combustion gases being lead through the kiln in countercurrent.  The gases entering the kiln contain only a small excess of air, air being admitted at one or more points through the kiln shell.  The content of free oxygen in the gases leaving the kiln is between 10 and 15 per cent.  A statement of the art relates to a process wherein fine-grained nickel matte is heated in a furnace, cooled, the lumps reduced to a powder, and the material reintroduced into the furnace.

Title: Electrolytic metal plating
IPC: C25D7/04
Filed: 1962-01-08
Abstract: <PICT:0961251/C6-C7/1> A metal object is electroplated, e.g. with Ni or Cr, while removing gas bubbles from between the object and an anode by making the object cathodic, moving the anode relatively to it and passing an electrolyte between the anode and cathode in the same direction as the anode's relative movement, the anode being placed so that the space between it and the cathode widens in the direction of the anode's relative movement.  Reference is made to electroplating tubes internally or externally and to electroplating sheets.  As shown, a Cr-Ni steel tube 1 is electroplated with Ni by making it cathodic, raising a truncated cone shaped Ni anode 3 through it and pumping an electrolyte containing a Ni salt upwardly between the anode and cathode.  The anode is raised by a motor-driven drum 5 and held centrally of the tube by non-conducting projections 17, e.g. of hard rubber. The electrolyte is circulated via conduits 10, 12, 20, and 13 by gas from a jet 19 which carries the electrolyte upwardly to a container 21 from whence it falls through the conduit 13.  The electrolyte may be heated or cooled by a heat exchanger 14. Gas bubbles produced during electrolysis can escape from a container 11.

Title: Apparatus for fabricating wood structures
IPC: B27F7/15

Abstract: 1,218,001. Attaching spiked plates. HYDRO AIR ENG. Inc. 6 Jan., 1969 [8 Jan., 1968], No. 819/69. Heading B4C.  Apparatus for pushing spiked plates N1, N2 into wooden truss joints comprises a press 9 having an upper jaw 27 on a bracket 25 joined to a fluid cylinder 31 and a lower jaw 33 forming part of the piston of the cylinder 31, the press being floatingly mounted on a carriage 47 comprising rails 49 and having rollers 53 engaged in fixed rails 23 for horizontal reciprocation by a fluid cylinder 57 having its piston rod connected to the carriage 47 by brackets 67, 71. The timber T constituting the truss is clamped to rails 39 and the lower nail plate N1 rests on a tray 43. In one embodiment the press 9 is connected to the carriage 47 by a spring suspension means 45, the cylinder 31 and hence the upper jaw 27 resting, via a bracket 55 on springs 73, 77 separated by a washer 93, and the lower jaw being partially supported with the cylinder 31 by the springs 73, 77 and partially supported on the upper end of a tube 85, which has a washer 89, Fig. 6 (not shown), abutting the spring 77 at its lower end, the other end being held on the rail 49 of the carriage 47. A rod 79 extends through the tube 85 and is fixed to the lower jaw at its upper end and has a washer 84 supporting a further spring 75 and adjusting nuts 83 at its lower end. Fluid entering the lower part of the cylinder 31 initially causes the cylinder and upper jaw 27 to move downwards compressing springs 73, 77 until the washer 93 is acted on by the spring 75, then equal forces act on each jaw which converge at the same rate. If one side of the wood of the truss T is harder than the other then the jaw will be stopped on the harder side and will continue on the other until the forces on each jaw are again equal. The suspension arra ngement 45 can be rotated about rollers 53, orthe springs on one side can be compressed more than on the other to compensate for warping of the wood. In a second embodiment the spring arrangement is replaced by a pneumatic compensating arrangement 101, Fig. 9, comprising an expansible chamber 103 having a diaphragm (107), see Fig. 11 (not shown), joined by a rod 109 and pivot 111 to the bracket 25, the chamber 103 being itself joined to the carriage 47 by a bracket 115 and rods 117 passing through cylindrical guides 123 attached to the bracket 25. The chamber 103 is supplied with compressed air below the diaphragm and can be relieved through a line 131 by a valve 133, controlled by a button 141 operated by the upward movement of a bolt 137 joined to the lower jaw 33 by a bracket 135, so that upward movement of the lower jaw 33 permits downward movement of the upper jaw 27. The compressed air supply may be the same as that used for the cylinder 57. The apparatus may have castors 18, Fig. 3, for movement on rails 19 and may be locked in position by a clamp 21 or it may be moved on an air cushion contained in a dome-shaped chamber 165, Fig. 9, and may be held at any position by a suction cap 171 connected to a vacuum pump.

Title: Method of reading data off a rotating disk-shaped recording medium
Inventor: BAAS DIETER
IPC: G11B21/10
Filed: 1996-04-03
Abstract: A disc playback apparatus includes a system for scanning a disc and storing in memory, an address associated with every point on the disc where the scanning device mistracks. A modified regulating signal is calculated for guiding the scanning device back onto the desired data track, from the value of the regulating signal generated by the tracking regulation circuit prior to track loss. The modified regulating signal is also stored in the memory, and during every subsequent reading of the disc, upon encountering track areas associated with stored addresses, the tracking regulation circuit is provided a corresponding modified regulating signal in order to maintain the scanning device near the desired data track. In further scans of the disc successive modified track regulating signals are iteratively generated and tested for tracking response until a substantially optimum modified signal is generated. The optimum modified regulating signal is then stored in memory associated with the address of respective disc defects. The optimum regulating signal is determinable by monitoring the polarity of the tracking signal after application of the modified signal. The first occurrence of a polarity change is an indication that the respective iteration of generating a modified signal has produced the desired signal.

An initializing system calculates a diversified key (Sd) on the basis of a basic key (Sb) processed by a biunique combination transformation (T). The key (Sd) recorded in the memory (M3) of a user card (CU3) is authenticated by an exploitation system (4), which calculates a certificate on the basis of the basic key (Sb), while the card (CU3) calculates a certificate on the basis of its key (Sd). These certificates must be identical, taken into account the properties of the transformation (T). The invention is applicable in particular to the secret keys recorded in memory cards.

Title: Circuit for correcting coefficient of echo canceller
Inventor: KIHARA KOICHI
IPC: H04B3/23
Filed: 1988-01-06
Abstract: PURPOSE:To prevent the divergence of the coefficient of an echo canceller in one direction of positive or negative without increasing the scale and processing quantity of the hardware by periodically multiplying the coefficient by a damping constant. CONSTITUTION:This circuit for correcting coefficient of echo canceller is constituted of multipliers 5-8, adders 9 and 10, a received signal square-sum register 11, a reciprocal number circuit 12, a received signal register 13, a coefficient register 14, a switching circuit 15, and a counter 16. Then the coefficient of an echo canceller is periodically multiplied by a damping constant. Since the coefficient is periodically multiplied by the damping constant, the coefficient is periodically damped and updated and does not divert even when it tends to divert in one direction of positive or negative. Therefore, divergence of the coefficient in one direction can be prevented without increasing the scale of the hardware and processing quantity of the firmware.
