Patent SE-300035-B (SE)
Inventor: WOLPERT T
IPC: H04M19/08
Filed: 1967-06-30
Abstract: 1,227,234. Battery charging systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. 28 June, 1968 [30 June, 1967], No. 31126/68. Heading H2H. A system for charging a battery comprises means whereby the battery may be charged at one or other of two rates in dependence upon the charging current. A battery A is charged from a D.C. source E<SP>1</SP> by way of a transductor T, which transductor comprises windings supplied from an A.C. source V1 and which are arranged to energize the operating coil of a relay R by way of a bridge rectifier, the contacts of the relay R being arranged to connect the battery to points on a potentiometer across the D.C. source E<SP>1</SP> which have different potentials. The transductor T is further supplied with a bias winding fed from a D.C. source V2. Initially, when the battery is discharged the charging current is effective to cause the output of the transductor to energize the relay R sufficiently to change its contact to the higher voltage point. As the charging current falls the output of the transductor falls until the relay contact once more assumes its lower voltage point, the battery then charging at a lower rate. The transductor T has a characteristic having three sections the middle section of which is steep relatively to the other sections and the arrangement is such that the relay operates only when the transductor is operating in the steep section of the characteristic.

Title: Doppler catheter
Inventor: MILLAR HUNTLY D
IPC: A61B8/06
Filed: 1986-09-15
Abstract: A steerable catheter having a Doppler crystal at the tip to measure the velocity of blood in vivo-and inferentially the blood flow. The catheter includes two passageways, one passageway being exposed to the blood stream with the other passageway containing the electrical leads to the Doppler crystal. The one passageway is dimensioned for receiving a wire guide for accurately manipulating the catheter.

Title: Method of and apparatus for the interchanging of troughs in interchangeable-trough tipping wagons
Inventor: KLUSMANN GERHARD
IPC: B60P1/34
Filed: 1988-09-14
Abstract: The invention relates to a method and device for changing troughs of dumpers with interchangeable troughs. In underground mining it is problematical to carry out a trough change because of the laterally restricted conditions since the troughs cannot be put down next to each other. According to the invention, the empty trough (2) is therefore initially raised from the transport vehicle (1) to such an extent that a full trough (3) can be pulled onto the transport vehicle in place of the empty trough. Subsequently, the empty trough is let down and put in place of the full trough. While the full trough is transported away, the empty trough left at the site can be loaded so that a quasi-continuous transport is obtained. <IMAGE>

Abstract: PCT No. PCT/SE93/00558 Sec. 371 Date Feb. 24, 1994 Sec. 102(e) Date Feb. 24, 1994 PCT Filed Jun. 23, 1993 PCT Pub. No. WO94/01150 PCT Pub. Date Jan. 20, 1994.A method for manufacturing an injectable preparation of a pharmaceutically active agent suitable for storage in a dual-chamber injection cartridge. A dual chamber injection cartridge is provided, including: a barrel; a front chamber for a solid component; a rear chamber for a liquid component; a displaceable front piston separating the front and rear chambers; a closure sealing the front end of the barrel; and a constriction between the front and rear ends of the barrel. The constriction has a non-circular cross-section and an openable bypass connection permitting passage of liquid between the rear and front chambers. Prior to opening the bypass connection, the front piston is positioned between the constriction and the rear end of the barrel. The constriction resists displacement of the front piston in a direction of the front end of the barrel when the piston is in the vicinity of the constriction. The constriction prevents displacement of the front piston toward the front end of the barrel when a vacuum exists in the front chamber. A pressure in the vicinity of atmospheric pressure exists in the rear chamber. The front piston is deformed while being displaced through the constriction in the direction of the front end of the barrel while overcoming the resistance. The deformation establishes the liquid bypass connection. The rear chamber is filled with the liquid component. The rear chamber is sealed. A solution of the pharmaceutically active agent is charged in the front chamber. The front chamber is sealed.

Filed: 2002-11-22
Granted: 2006-06-28
Abstract: A fuel cell assembly supplies water and water vapour by-product to a cooling water circuit delivered to a thermal storage tank from which it can be recycled to the fuel cell stack as direct input to the membrane electrode assemblies, for use as fuel/oxidant preheat and/or direct water injection to the membrane electrode assembly. The purity of water delivered to the membrane is thereby assured. The thermal storage tank allows for a decoupling of the thermal and electrical loads on the fuel cell stack in a combined heat and electrical power delivery unit. Under low external electrical loads, the fuel cell stack and its cooling circuit may be used at high capacity to provide hot water.

Title: Method and arrangement for guiding a user along a target path
Inventor: HULL RICHARD
IPC: H04L12/28
Filed: 2003-07-24
Granted: 2006-04-12
Abstract: An audio-based guide arrangement is provided for guiding a user along a target path by the use of virtual audio beacons. The user's current location is sensed and compared to the target path. Sounds are fed to the user, for example through stereo headphones, to simulate one or more audio beacons appearing to be located in a direction at least approximating the direction of the target path onward from the user's current position. Preferably, each successive location of the audio beacon is determined by determining a segment onward from the user's current position of a piecewise linear approximation to the target path, and setting the apparent location of the beacon at or relative to the end of this segment.
