Patent FI-971422-A (FI)
Inventor: HOLCMAN ALEJANDRO RAUL
IPC: H04B7/26
Filed: 1997-04-04
Abstract: The filter of the present invention pre-processes signaling messages transmitted by the base station while the radiotelephone is in the idle mode. The radiotelephone informs the filter of the roam status and idle status and identity of the radiotelephone. The filter then intercepts the incoming signaling messages while the processor is in the sleep mode conserving power. When the filter detects a message requiring further processing by the processor, the filter interrupts the processor to process the message.

Abstract: 1,031,470. Semi-conductor monostable circuits. JOSEPH LUCAS (INDUSTRIES) Ltd. Dec. 12, 1963 [Dec. 21, 1962], No. 48290/62. Addition to 1,031,458. Heading H3T. In a monostable circuit comprising a semiconductor controlled rectifier of the kind which can be switched from the conducting to the non-conducting condition by the application of a suitable pulse to its gate electrode, the application of a positive triggering pulse from pulse source 9 renders the semi-conductor controlled rectifier 10 conducting whereupon capacitor 16 charges through resistor 17 towards the voltage established across load 11 until the break down voltage of the fourlayer diode 15 is exceeded, whereupon the discharge of the capacitor through the diode 15 and cathode-gate path of the rectifier 10 switches the latter off. Diode 18 provides a low impedance discharge path for the capacitor after the rectifier 10 has been switched-off. In a modified circuit. Fig. 2 (not shown), the capacitor 16 is charged through a charging resistor from the voltage established across a Zener diode connected, together with a dropping resistor, in parallel with the load. The charging rate and hence the " on " time of the circuit is thus made independent of supply-voltage variations.

Abstract: 851,410. Agglutinated fibrous materials; paper. DRELICH, A. H. Jan. 11, 1957 [Jan. 11, 1956], No. 1187/57. Classes 96 and 140. A washable non-woven fabric comprises a layer of overlapping, intersecting fibres in positions generally parallel to the general plane of the fabric and extending in a plurality of diverse directions parallel to the said plane, the fibres being closely assembled through the thickness of the fabric and loosely assembled (relative to their spacing through the thickness) parallel to the median section of the fabric forming myriad small interstices between them, and a multiplicity of randomly but substantially uniformly distributed heat-fused granules of bonding material uniting the fibres and having an average cross-dimension in the order of 14 to 70 times the average diameter of the fibres, each fibre being bonded by a granule at least two or three times along its length. By the term " median section " is meant the locus of all points located midway between the fabric surfaces. Specified fibres are regenerated cellulose, nylon, viscose rayon, cotton and wood. Specified binder materials are plasticized cellulose acetate, plasticized ethyl cellulose, nylon, polyvinyl chloride, polyethylene, polymethane, polystyrene, polyvinylidene chloride and polyvinylidene cyanide. The binder granules may be distributed among the fibres during or after the formation of the layer. The layer may be formed by carding or by air-laying or papermaking techniques. The bonds may be formed by distributing the binder granules in the fibrous layer and applying heat and pressure to cause the binder to flow slightly and pass substantially through the web and embed the fibres. The binder content may range from 10 to 35% of the weight of the fabric. The binder granules may be distributed amongst the structural fibres during or after formation of the fibrous layer. The layer may be formed by air-laying or paper-making methods. Fibres of normal textile length may be used. Heat and pressure may be applied to the granule containing layer by placing it between heated platens in a press, passing it between heated rollers or between pressure rollers in an oven or first heating the layer and then running it while hot between unheated calender rollers. As shown, Fig. 1 is an enlarged schematic plan view of a portion of a fabric according to the invention and Fig. 2 is an enlarged schematic sectional view along the line 2-2 in Fig. 1. Fibres 11, extending in a plurality of diverse directions in planes generally parallel to the medium section of the fabric are bonded by a multiplicity of spaced solid granule bonds 12 extending through the thickness of the fabric substantially from one surface to the other. The fibre segments between the bonds provide a multiplicity of fluffy web areas 14. Examples disclose the making, by paper-making techniques, of layers comprising viscose rayon fibres and binder particles of ethyl cellulose or nylon followed by subjection to heat and pressure.

Title: Axial piston machine
IPC: F01B3/00
Filed: 1972-01-12
Abstract: 1355002 Axial piston pumps ROBERT BOSCH GmbH 12 Jan 1972 [12 Jan 1971] 1515/72 Heading F1A An axial piston pump includes a fluid inlet 41, fluid outlet 42 (or vice versa), and pistons 9 which slide in bores 8 in a rotating cylinder drum 7, driven by a shaft 3. The ends of the pistons are supported by sliding pads 10 which slide around the surface 11 of a control plate 12, the tilt of which may be varied by rod 20 and piston 19 to adjust the stroke of the pistons 9. A recess 15 in each of the pads 10 communicates with its associated bore 8, so that fluid to be pumped may form a hydrostatic bearing between the pad 10 and the surface 11. Lubricating ducts 48 extend from that part of the surface 11 traversed by the sliding pads 10 to grooves in the back bearing surface 18 of control plate 12, so that fluidpressure zones will be periodically created and subsequently decay at the back bearing surface as the fluid filled recesses 15 sweep over the lubricating duct inlets in surface 11. This allows easy adjustment of the control plate 12. In modifications adjacent pairs of lubricating ducts may be provided Fig. 3 (not shown), the lubricating duct may include a non-return valve and a reservoir containing a spring piston whereby the life of the pressure zone may be prolonged, Fig. 4 (not shown), or the control plate back bearing surface may include flattened portions Figs. 5a, 5b (not shown). In pump constructions in which a flat tilting control plate 95, Fig. 8 mounted on bearing trunions 96, 99 is utilized, the lubricating ducts 103, 104 extend through the plate to form the pressure zones on the trunion peripheries. As shown each duct feeds at least one pressure zone on each trunion, the arrangement preferably being such that the duct e.g. 104 aligned with the pump delivery side communicates with a pressure zone of higher capacity on the trunion on the delivery side of the pump and with lower capacity zone(s) on the other trunion. In a modification Fig. 9 (not shown) for use in a non- reversible pump, the lubricating duct inlets are so located in the sliding surface of the control plate as to be simultaneously covered for a time by a single sliding pad, the duct inlet feeding the delivery side trunion being covered however for longer than the other duct inlet.
