Patent FI-19992248-A (FI)
Inventor: ODENWALDER JOSEPH P
IPC: H04B1/707
Filed: 1999-10-18
Abstract: A set of individually gain adjusted subscriber channels (402, 404, 411, 415) are formed via the use of a set of orthogonal subchannel codes (Wc, Ws, Wf) having a small number of PN spreading chips per orthogonal waveform period. Data to be transmitted via one of the transmit channels is low code rate error correction encoded and sequence repeated before being modulated with one of the subchannel codes, gain adjusted, and summed with data modulated using the other subchannel codes. The resulting summed data (410, 420) is modulated using a user long code and a pseudorandom spreading code (PN code) and upconverted for transmission. The use of the short orthogonal codes provides interference suppression while still allowing extensive error correction coding and repetition for time diversity to overcome the Raleigh fading commonly experienced in terrestrial wireless systems. The set of sub-channel codes may comprise four Walsh codes, each orthogonal to the remaining codes of the set. The use of four sub-channels is preferred as it allows shorter orthogonal codes to be used, however, the use of a greater number of channels and therefore longer codes is acceptable. Preferably, pilot data is transmitted via a first one of the transmit channels and power control data transmitted via a second transmit channel. The length, or number of chips, in each channel code may be different to further reduce the peak-to-average transmit power for higher rate data transmission.

The catalyst is activated by a first pretreatment with air at 250 DEG  to 400 DEG C for 1 to 20 hours, followed by a second pretreatment with the gaseous reaction mixture at 350 DEG  to 450 DEG C for from 1 to 10 hours.  Other oxides which may be present are those of Cu, Ag, Au, Ca, Sr, Ba, Mg, Zn, Cd, B, Ti, Zr, Si, Ge, Sn, P, As, Sb, Bi, Cr, W, U, Se, Te, Mn, Fe, Co, Ni, the total amount of such oxides normally being less than 10% based on the weight of MoO3.

IPC: H01F27/14
Abstract: 1,084,337. Regenerating transformer oil. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 26, 1964 [July 9, 1963], No. 27172/63. Heading C5E. A circulating system for directly absorbing moisture and other electrically deleterious substances from transformer oil comprises an arrangement of pipes in a circuit which allows the oil from the transformer tank to pass continuously through a pair of driers containing molecular sieve desiccant material, and permits the isolation or removal of one drier for reactivation while the other drier remains in use. The molecular sieve is preferably a 3-5 Š sieve.
Patent GB-1095391-A (GB)
IPC: B23Q1/01
Abstract: 1,095,391. Machine guideways. DEAN, SMITH & GRACE Ltd. Nov. 10, 1964 [Nov. 3, 1963], No. 43361/63. Heading B3B. Means for guiding a saddle in a horizontal plane on a bed of a lathe or other machine tool in which the bed has a top horizontal surface 1, a surface 3 at right angles to the top surface and an opposed inclined surface 4 at an acute angle to the top surface. The co-operating saddle 5 is provided with a wedge-shaped pad or pads 6 which act(s) as a guide bar when the saddle 5 is moved relative to the bed. Screw means 7 are provided in association with the guide bar to facilitate vertical adjustment of the guide bar to reduce lateral clearance between the bed and saddle. The above guide means may be incorporated with other known forms of guides on machine tool beds.
Patent GB-1144742-A (GB)
Abstract: 1,144,742. Ovens; heat-distribution therein. MOORWOOD VULCAN Ltd. 7 Nov., 1966 [9 Nov., 1965], No. 49787/66. Heading A2A. In a hot air oven, Figs. 1, 3 and 4, through which air, which has been heated indirectly by gas burners, is circulated by a rotating fan 38 to maintain uniform heating throughout the substantially rectangular baking or heating chamber 23, this chamber is bounded by upper and lower, horizontal, inner walls, two vertical, inner side walls 27 perforated by holes or slots 27<SP>1</SP>, and a vertical, inner rear wall 36, provided with a central, circular opening 37 leading to the fan 38, and with upper and lower openings 51 and 52. The oven is provided with a heat-insulating jacket comprising outer walls 18, heat-insulating material 20 and intermediate walls 19. The walls 27 and 36 and the adjacent intermediate walls 19, define two heat-exchange chambers 26, and a connecting, air-distributing chamber 35. A plurality of openended vertical, e.g. aligned, tubes 30, constituting heat-radiators or exchangers, pass through each chamber 26. The tubes 30 may be spaced uniformly or non-uniformly apart. The lower ends of the tubes 30 are connected to housings 29 receiving flames and gaseous combustion products from horizontal tubular gas burners 28. The waste combustion products are discharged from the upper ends of the tubes 30 into a flue 31 leading into a chimney 32. The holes or slots 27<SP>1</SP> are equal in size and their distribution, e.g. in groups, over the walls 27 varies, as shown in Fig 1, to compensate for fall in temperature from bottom to top of the tubes 30, and between the back and the front of the chamber 23. Access to the chamber 23 can be obtained through a front doorway 21, provided with hinged doors 22.
