Title: Handle assembly for a toilet seat
Inventor: MILLER CHRISTOPHER
IPC: A47K13/10
Filed: 2009-05-18
Abstract: A handle assembly for a toilet seat comprises a base member 1 securable to the underside of a toilet seat, for example by adhesive or screws, and a handle 4 having a mounting member 7 projecting therefrom. The mounting member is engageable with holding means 6 on the base member, the mounting member and holding means co-operating to hold the handle in position during normal use, but permitting separation one from the other when sufficient force is applied to the handle.

Title: Determining the access rights of a wireless communication unit to use a selected internet protocol traffic offload route
Inventor: GUTTMAN ERIK
IPC: H04L45/24
Filed: 2009-08-21
Abstract: A method for identifying whether a selected Internet protocol traffic offload (SIPTO) route is allowed to be used by a wireless communication unit. Subscription profile data associated with the wireless communication unit is stored in a home subscriber server (HSS) database, where the subscription profile data comprises an indication of whether the wireless communication unit has access rights to use a SIPTO route. Then, a SIPTO indicator is generated for informing a network element that the wireless communication unit is allowed to use the SIPTO route. Hence, if a wireless communication unit (UE) 315 is in the coverage area of a radio access node, e.g. evolved Node B (eNB) or Home eNB (H(e)NB), 320 that offers SIPTO support, the network 310 may offload traffic from the core network by providing an IP data flow between the UE 315 and an external packet data network (PDN) server 345 via the radio access node 320.

Title: Electrically operable fluid valve means
IPC: F16K31/06
Filed: 1971-05-11
Abstract: 1357552 Valves VYZKUMNY USTAV AUTOMATIZACNICH PROSTREDKU 11  May 1971 [12 May 1970] 10144/73 Divided out of 1357551 Heading F2V An electrically-actuated fluid valve includes an inlet bore, an armature and a valve seat, all having a common axis. The armature has a valve part which seals against the valve seat when an associated solenoid is not energized and which is raised from the seat to allow fluid to flow when the solenoid is energized. The valve may be used in an assembly as described in Specification 1,357,551. As disclosed, the valve has an inlet bore 21 and an axially movable armature 27 with an axial bore 28. The end of bore 28 is sealed by plug 33, the plug being pressed against a valve seat, forming one end of an outlet bore 32, by a spring 35 which urges the armature downwards. The other end of the spring presses against a sealing disc 34. When solenoid coil 26 is energized the armature rises so that air, passing via bore 21, bore 28, and radially extending holes in the armature, is discharged via the bore 32. Armature 27 and the end of bore 21 are prevented from abutting by a brass cylinder 25 to avoid magnetic sticktion effects. There is no member between the armature and the former 24 of the solenoid. The valve may be secured with its axis perpendicular to a base-plate by means of a nut 30.

Title: Improvements in or relating to the recovery of normally gaseous solvents used in oil extraction
IPC: C10G21/00
Filed: 1943-06-28
Abstract: Normally gaseous, water-insoluble solvents maintained in the liquid state by means of pressure, are recovered from oleaginous materials by heating the mixture under a pressure sufficiently high to allow condensation of the solvent at ordinary cooling-water temperatures, to a temperature at which the major proportion of the solvent is vaporised; the remainder of the solvent is then recovered by reducing the pressure, passing steam through the mixture, separating steam from the evolved mixed vapours by condensation, and absorbing the solvent vapours in untreated oleaginous material.  The process is applicable to the recovery of propane and butane used in the deasphalting, deresining and dewaxing of hydrocarbon oils.  The oil to be deasphalted is fed through line 1 into tower 2, where it absorbs low pressure propane vapours, introduced through line 3 and coming from the steam separation step (see below).  The oil then flows to mixer 8, where it is mixed with liquid propane, withdrawn from tank 9.  The mixture passes to a settling chamber 14, maintained at a pressure between 350 and 500 lbs. per sq. inch, in which the asphalt and resins separate out.  The deasphalted solution is introduced into tower 18, heated at 300 DEG  to 350 DEG  F., where from 90 to 98 <PICT:0583171/III/1> per cent. of the propane is vaporised and leaves the tower by line 20.  The asphalt from settling chamber 14 also contains propane, the major proportion of which is vaporised in drum 22 and leaves via line 24.  The two streams of high-pressure propane vapours are united in line 25, condensed, and returned to tank 9.  Deasphalted oil, withdrawn from the base of tower 18, is stripped of remaining propane by means of live steam in tower 32.  The asphalt withdrawn from drum 22 is similarly stripped in tower 37.  The vapours from towers 32 and 37 are united, and introduced into jet condenser 41, where the steam is condensed but not the propane; the latter passes on to the absorbtion tower 2.

Abstract: 944,947. Photoelectric densiometers. CARL ZEISS JENA VEB. March 25,1960, No. 10719/60. Heading G1A. The mass of an organic cell is measured by preparing a highly magnified outline drawing of the cell, and using this to control the photo-electric point-by-point scanning of the cell to produce signals which are integrated. The cell containing tissue 7 is viewed through a microscope 8, 9, having a lens 10 which may be moved perpendicular to the optical axis so that an eyepiece graticule may be traced round the cell or the part thereof of interest. Movements of the lens 10 are transmitted by a pantograph 11 to a metal stylus 12 which produces an outline drawing 14 of the cell. The area within the outline is made conducting and outside insulating. The stylus is then made to traverse the outline in parallel lines, having its direction reversed and being shifted to the next line each time the stylus meets the insulation. During scanning the photo-cell output is fed to an integrator. Further styli may be provided to blank the photo-cell signal in unwanted parts of the cell.

Title: Arrangement for the automatic regulation of the degree of transmission of transmission systems, particularly of high frequency transmission systems
IPC: H04B7/005
Filed: 1928-04-11
Abstract: 291,083. Siemens & Halske Akt.-Ges. May 28, 1927, [Convention date], Fading, preventing ;-Relates to an improved method of automatically regulating the strength of received signals to compensate for fading effects, of the kind described in the Specification 289,050, wherein a control frequency lying outside the signal frequencies is applied at the receiving end to shift the effective grid-bias of a valve receiving both signal and control frequencies. As shown in the Figure, the output circuit of the first valve or rectifier g comprises two filter circuits c, s, the first of which passes the useful signalling frequencies to an amplifier n, whilst the second separates the special control frequency and passes it to the grid of an auxiliary valve h. A resistance r in the output circuit of the latter is also included in the grid circuit of the valve g, and raises or lowers the effective grid potential of this valve in accordance with fluctuation in the received signals due to fading &c. The auxiliary valve h may similarly control the effective grid bias of an amplifier valve inserted before the detector g. When used for a picture transmission, the usual synchronizing frequency may also serve as the gain-control frequency. Alternatively the grid or anode currents of the valve h can be used to control the grid bias of the first amplifier valve, or to operate the mechanical form of control relay described in Specification 289,050.

Abstract: 542,145. Producing nickel-iron powder for magnetic cores. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and ROSEBY, P. N. June 25, 1940, No. 10838. [Class 38 (ii)] Nickel-iron powder for use in the manufacture of dust cores for loading coils &c. is prepared by mixing nickel powder, produced for example by the carbonyl process, with iron oxide or iron oxalate, heating the mixture to 600‹-1200‹ C. in a reducing atmosphere such as hydrogen, and crushing the sintered mass. The final particle size may be determined by the size of the particles of the nickel powder if the particles of the oxide or oxalate are much smaller than the nickel particles so as to form a coating thereon. The final powder may, however, be ground in a ball mill if accurate determination of particle size is required.
