Patent NO-175800-B (NO)
Inventor: SCHWENT DALE G
IPC: H04B1/04
Filed: 1990-06-20
Abstract: An integral phase shifting network (215,216,217) of a transmitter filter (104) provides a means to reduce the size and increase the efficiency of an antenna coupling network. The network to shift the phase of the transmitter filter (104) is printed by depositing conductive material directly on a ceramic block (230) using low-loss circuit elements and can be tuned easily by removing conductive material if required in certain applications. By utilizing an integral phase shifting network (215,216,217), either transmit filter (104) or receive filter (112) having a highly reactive and capacitive out-of-band impedance in the receive or transmit band, respectively, can be connected to a common antenna port without external transmission lines.

Abstract: 977,315. Gear pumps and motors. INTERNATIONAL HARVESTER CO. April 17, 1961 [June 17, 1960], No. 13736/61. Heading F1F. An hydraulic gear pump (or motor) comprises a casing including a main portion 1, Fig. 1, having an opening therethrough formed with intersecting parallel bores 3, 4, Fig. 2, housing a unit 40 comprising intermeshing gears 41, 42 flanked on either side by support members 49, 50 having counterbores 53 in each of which is pressed a roller bearing unit 51 forming the sole gear supporting means. Each support member 49, 50 has arcuate peripheral lands 60, 61 extending across the whole thickness of the member adjacent the pump inlet 59 and closely fitting its associated casing bore and lands 80 of lesser extent disposed opposite to the lands 60, 61 and adjacent the pump outlet 58. The driving gear 41 is formed with a bore 43 having splines 44 engaged by splines 45 on the end 29 of a driveshaft 17 which is solely supported on a double row taper roller bearing 18 mounted in a bore 20 in an end casing portion 7 to reduce excentricity on the shaft end 29. The splines 45 and the end 29 are respectively of lesser diameter than the bore 43 and splines 44 to allow spacedapart relationship between the shaft end 29 and the pre-assembled unit 40. The radii of the lands 60, 61 and of the gears 41, 42 are adjusted with respect to each other so that during pump operation the gears only lightly contact the casing bores, avoiding excessive bearing forces and "milling" of the casing. Pistons 86, 87 loaded by springs 108, 109 are sealingly received in bores 90, 91 in a casing end plate 5 and subjected on their rear faces to pump outlet pressure. Pump outlet pressure is also transmitted through spaces 75 between the lands 80, 60 and lands 80, 61 of the support member 49, axially through the gear teeth and similar spaces 75 between the lands of the support member 50. The rear piston faces are eccentric with respect to the gear axes so that the unit 40 is in substantial hydraulic balance with the springs 108, 109 providing the axial sealing forces. Pump pressure acting over sealing arcs S, S<SP>1</SP> is more than balanced by pump pressure acting on arcs subtended between the outer ends of the arcs S, S<SP>1</SP> and the common plane of the gear axes to provide resultant forces R, R directed towards each other which eliminate outwardly spreading forces acting on the gears.

Abstract: 1,078,829. Vocoders. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 29, 1965 [April 6, 1964], No. 13170/65. Heading H4R. In a vocoder system each spectrum channel is sampled once per cycle of the fundamental frequency of the speech signal and the resulting signals transmitted in digital form. Fig. 1 shows a preferred embodiment in which speech from a microphone M is divided into a number of frequency bands by band-pass filters BP the signals from which are rectified by rectifiers G and passed through low-pass filters TP 1  to form analogue signals corresponding to the variations in energy of the individual frequency bands of the original speech. The speech is also fed through a low-pass filter TP 2  to a zero crossing detector ND to develop a pulse at the fundamental frequency of the speech. The fundamental frequency pulse is fed through a delay unit VZ, comprising e.g. cascaded monostable switching circuits, to synchronize the signal with the spectrum signals, before the signal is applied to a data processing unit EDV. The data processing unit controls the sampling switch S so that each spectrum channel is sampled one per pitch pulse. The resulting samples are fed via an analogue digital converter to the data processing system EDV for storage and subsequent transmission. The fundamental frequency signal is also digitized in the data processing unit by a counter.

Title: Use of naphtha in carbo-metallic oil conversion
Inventor: MYERS G
IPC: C10G11/18
Filed: 1982-03-12
Abstract: A process is disclosed for the production of high octane gasoline and/or other valuable lower molecular weight products from carbo-metallic oils. Examples include crude oil, topped crude, reduced crude, residua, the extract from solvent deasphalting and other heavy hydrocarbon fractions. These carbo-metallic oils contain quantities of coke precursors and heavy metal catalyst poisons substantially in excess of what is normally considered acceptable for Fluid Catalytic Cracking (FCC) and substantial amounts of sulfur, nitrogen and other troublesome components may also be present. Such carbo-metallic oils are converted to the desired products in a catalytic conversion process where the oil feed is mixed with naphtha and brought together with a high-metal content cracking catalyst. Named "RCC" (Reduced Crude Conversion) after a particularly common or useful carbometallic feed, the present process is by no means restricted to reduced crude or to oils of petroleum origin, having utility in the processing of oils from coal, shale and other sources.

Title: Decorative laminate having core sheet impregnated with vinyl ester resin
Inventor: DION ANDREW
IPC: B32B27/04
Filed: 1991-07-16
Abstract: A heat and pressure consolidated decorative laminate is disclosed having at least one core sheet which is impregnated with a vinyl ester resin. The resin is preferably derived from an epoxide terminated resin and an ethylenically unsaturated carboxylic acid. A particularly preferred epoxide terminated resin is the reaction product of bisphenol A and epichlorohydrin. Particularly preferred as the ethylenically unsaturated carboxylic acid are acrylic and methacrylic acid. The color of the core sheet(s) of decorative laminates embodying the invention is relatively light and thus can match the color of the face of optional back layers of the laminate where these, as is usual, are of a relatively light color. The laminates exhibit high heat resistance, flexibility, and good resistance to cracking and tearing.

Title: Method of manufacturing a wall ironed can
Inventor: HEYES PETER JOHN
IPC: B21D51/26
Filed: 1991-07-22
Abstract: In a method of drawing and wall ironing a can body, a blank (1) is cut from a laminate of aluminium or alloy and a polyester film. The blank is lubricated and drawn to a cup (7) having a side wall (8), which is then wall ironed. A terminal margin (14) of the side wall (13) of the wall ironed can is heated to a temperature above 100 DEG C but below the crystalline melting point of the polyester film in order to prevent delamination of the polyester film from the side wall of the can during subsequent washing of the can. A benefit of the process is that the heating of the side wall margin (14) does not soften the aluminium or aluminium alloy body. <IMAGE>
