Patent FI-20041118-A (FI)
Inventor: HUAH JIM J
IPC: H04B1/40
Filed: 2004-08-26
Abstract: A subscriber unit of a time division multiple access (TDMA) radiotelephone system is, from a power consumption standpoint, reconfigured in each time slot of a TDMA frame to a power consumption tessellation in which subscriber unit circuit components not needed for communication signal processing in that time slot are powered down, and other components are powered up.Some circuit components are powered down by switching their power supply circuits. In order to minimize the extent of circuitry that must be provided to distribute power consumption control signals, other techniques (which utilize circuitry provided for other purposes), such as clock frequency control or power down commands, also are utilized to modify controlled circuit component power consumption without actually controlling power supply circuits. Loop connection length between the subscriber unit and the subscriber's telephone set, or other terminal equipment, is limited to a length which is much less than the length of a radio link on which the subscriber unit operates. Programmable ring frequency logic controls the frequency of a ringing signal generator, and a high frequency ring control signal is switched on and off in the cadence of ringing operation. Also an expansion header is provided to enable serving plural subscriber loop circuits with the same radio equipment for reducing per line power consumption.

Abstract: 1,227,476. Welding by pressure. BENDIX CORP. 18 Dec., 1968 [25 Jan., 1968], No. 60222/68. Heading B3R. In joining two metal bodies surface oxides are removed therefrom by a process including the final operation of eliminating the penultimate preparing agent with alcohol, the oxide free surfaces are covered, before the alcohol is evaporated, with a substance capable of complete evaporation under solid state diffusion bonding conditions, the covered surfaces are mated and are placed in a chamber where reduced pressure, neutral atmosphere or reducing atmosphere is present to vaporize the substance completely and solid state diffusion bond the bodies. Examples of suitable substances are alcohols, glycerine, glycols, polybutenes, acrylic resins, lacquers and polystyrenes. In making a fluidic device a lamina 10, Fig. 2, of aluminium, beryllium, chromium, titanium, alloys based on these metals, stainless steel, super alloys based on iron, cobalt or nickel, refractory alloys based on chromium, molybdenum, tungsten, niobium, tantalum, manganese, vanadium, zirconium or alloys based on magnesium, silicon, cobalt, nickel, yttrium, cerium, thorium and zirconium and having a flow passage 12 therein has its oxide coating 16 removed chemically. The oxide free and alcohol coated body is then immersed in a bath of alcohol and several similarly oxide free and alcohol coated laminµ are assembled while immersed in the alcohol in a jig or fixture and preferably clamped. The clamped assembly is removed from the bath and placed in a vacuum furnace (or a furnace using neutral or reducing atmosphere) where the assembly (in the case of aluminium alloy) is heated at 1050 F. for two hours or at 880 F. for five hours. The alcohol evaporates and solid state diffusion occurs to produce an assembly 23, Fig. 6, bonded by alloy 24 at the interfaces. In a modification the cleaned laminµ are coated with glycerine, glycols, polybutenes, acrylic resins, lacquers or polystyrenes, assembled and then placed in the bonding furnace where the substance evaporates and solid state diffusion is effected.

Abstract: 1,227,890. Warp let-off motion. RUTI MACHINERY WORKS Ltd. 4 Dec., 1969 [4 Dec., 1968], No. 59371/69. Heading DIE. A warp let-off motion comprises a brake 26 for a warp beam 11, a tensioning roller 14 urged towards the warp 12 by first biassing means 25, second biassing means 29 which tends to apply the brake and linkage coupling the roller 14 to the brake and arranged to release the brake against the action of the biassing means 29 and to allow the biassing means 29 to apply the brake, alternately, depending on the position of the roller 14. In operation of the loom as the warp 12 is used up and with the brake applied the roller 14 moves to the left carried by arms 16 which pivot about an axis 17 and, through a link 20 and on 21, pivot a lever 22, 23 compressing the spring 25 and moving the lever arm 23 into engagement with an abutment 30. Further roller movement pulls down the abutment 30, and a rod 31 and releases the brake. The roller 14 is then moved to the right by the spring 25 as warp is let off and the lever arm 23 pivots clockwise, rising from the abutment 30 and permitting the spring 29 to reapply the brake. To provide a more uniform warp tension the roller 14 is arranged to move to the left of the vertical through the pivot 17 thereby producing a force counteracting the increased tension in the spring 25 as it is compressed by the moving roller.

Abstract: 1,228,130. Fluid-pressure servomotor systems. GPE CONTROLS Inc. Aug. 21, 1969, No.41803/69. Heading G3P. A tank venting valve has a main closure member 10 which is-moved off seat 12 when either one of a pair of pilot valves 30, 40 is opened by excess under or over pressure in the tank. Pilot valve 30 is mounted in fixed plate 16, and has a loose ball 26 seated by a permanent magnet 24, whilst pilot valve 40, which is mounted in closure member 10, has a single beat closure member 38 loaded by both a magnet 36 and a spring 46. Check valves 18, 20, each having a flow capacity less than that of the pilot valves, are also mounted in the closure member 10 and plate 16. In operation, an over pressure in the tank opens valve 18, admitting pressure to the interior of bellows 15 and so opening valve 30 which allows the pressure in the tank to open the main closure member 10. With an under pressure condition valve 18 remains closed whilst valve 20 opens to connect the bellows to atmosphere whereby the lower pressure in the tank opens valve 40 so that fluid can flow from the bellows to the tank faster than the bellows can be refilled through valve 20, and main closure member 10 therefore opens.

[Also in Division B4] A method of transversely shearing a bar workpiece comprises laying the bar workpiece in a locating groove in a support and shearing it while at least the part of the workpiece engaged by the shear is restrained from movement in the axial direction. As shown, Fig. 7, a bar 6 located in groove 14 in base 1<SP>1</SP> is sheared by a blade 3 moving in a slot 9 whilst pressure is applied to the bar by members 10 and 11. The groove 14 may be stepped so that the outer edge of either or both of the pressure members partially shears the bar before the shearing stroke proper to increase axial restraint, Figs. 8 and 12-14 (not shown). The bar may be restrained between a fixed (2) and an adjustable end stop (5), Fig. 6 (not shown), with a member (7) mounted over the bar adjacent the blade to prevent upward bowing of the bar. One fixed end stop may be used in conjunction with one pressure member such as member 10, Fig. 10 (not shown), or a pressure member which also partially shears the bar, Fig. 11 (not shown). The single blade 4 may be replaced by an assembly 12 of blades 12<SP>1</SP>, Figs. 15 and 16. In a modification of the method of the invention, the blade assembly 12 is used without separate means for restraining axial movement of the bar, the blades constituting these means for the portion of the bar inwardly of the outermost blades 12<SP>1</SP>, the rest of the bar being unrestrained (Fig. 9, not shown). Alternatively restraining means such as an end stop may be provided at one end only of the blade assembly, Fig. 17 (not shown).
