Title: Electromechanical impulse generator - is for electricity meter counting applications and uses bar magnet fixed to shaft and mechanical pickoff linkage
Inventor: LIEBSCHER ERICH
IPC: G01R11/02
Filed: 1975-09-02
Abstract: An electromechanical impulse generator is for application in electricity meters in which a bar magnet is used to generate impulses via a mechanical linkage, and which avoids the problems of false impulses. It consists basically of a bar magnet (1) fixed to a central shaft (2) which in turn is associated with the wattmeter or other similar equipment, so that the magnet rotates at a rate dependent on the electricity consumption. Mounted beneath the magnet is a spring loaded (3) eccentric cam (4) and a disc (8) carrying posts (13, 14) which are driven round by a matching mechanical contact on the magnet (9). The mechanism is arranged to push a plate (12) to and fro at a rate dependent on the consumption rate, and so to affect the closure of a magnetically operated switch (10) mounted in the repeatedly reversing magnetic field. This in turn produces the required impulses.

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.
