Abstract: An automatic injector comprises a housing, a tubular cartridge disposed in the housing, the cartridge having a rearward portion thereof with a predetermined inner diameter and an inwardly extending shoulder connecting a forward portion of the cartridge with a smaller inner diameter than the predetermined diameter. A charge of liquid medicament is normally disposed in the cartridge, and a needle is disposed within the housing and adapted to communicate with the medicament through a forward end of the cartridge to dispense the medicament therethrough. A plunger disposed within the cartridge and rearwardly confines the medicament and has a rearward portion with a diameter sized to form a seal with the predetermined inner diameter of the rearward portion of the cartridge. The plunger is movable forwardly through the cartridge in slidingly sealed relation with respect thereto to displace the medicament through the needle. The plunger has a forward portion thereof being of a relatively reduced diameter than the rearward portion of the plunger and shaped i) to enter the forward portion of the cartridge to displace medicament therefrom through the needle and ii) to maintain fluid communication between the forward end of the cartridge through which the needle communicates with the medicament and a space within the cartridge between the plunger and the inwardly extending shoulder of the cartridge so as to dispense medicament from the cartridge until the plunger engages the shoulder and/or the forward end of the cartridge. A releasable energy source moves the plunger forwardly through the cartridge to dispense the medicament through the needle.

Abstract: Biomolecule analysis using anodic oxidation of aqueous sodium 9, 10- diphenylanthracene-2-sulfonate (DPAS) and 1- and 2-thianthrenecarboxylic aci d (1-THCOOH and 2-THCOOH) in the presence of tri-n- propylamine (TPrA) as a coreactant in aqueous solution produces electrogenerated chemiluminescence (ECL). In addition, the cathodic reduction of DPAS in the presence of peroxydisulfate (S2O82-) as a coreactant also produces ECL in an acetonitril e (MeCN)-water solution (1:1 by volume). The oxidation of chlorpromazine (CPZ) produces an ECL emission in the absence of an added coreactant following an unprecedented "self-annihilation" mechanism.

Title: Device with at least one hydraulic axis
Inventor: TRUNINGER ROLF
IPC: B29C45/50
Filed: 1996-05-17
Granted: 2005-03-15
Abstract: The new invention proposes control of the power of hydraulic axes on the electrical side, using the power electronics, and no longer on the hydraulic side. This makes it possib le to operate the hydraulics as an open circuit system, and, in particular to use one signal pump to drive and number of axes sequentially. The main advantage is that, on one hand, the feedback control quality of purely electro-motorically driven axes can be achieved, and, above all, that the energy loss sustained in the previous mode no longer arises. One particular advantageous effect of the ne w drive is produced when it interacts with a potential energy source which defines the return force acting on the drive. A particularly preferred form is a gear pump with internal gears. Although t he system as a whole is a four quadrant drive system, it operates as a two quadrant drive system on the pump drive side. The new invention has made it possible to apply the known "control philosophy" used in electrical engineering, and in particular the control of power and feedback control of power, to hydraulic power systems.
