Title: Circuit de reglage et procede pour compteur d'energie electrique a semi-conducteurs
Inventor: COOPER DAVID M
IPC: G01R19/00
Filed: 1989-07-13
Abstract: Un circuit d'étalonnage pour un compteur d'électricité à semi-conducteurs comprend une pluralité de résistances formées sur un circuit intégré. Les résistances sont connectées par un réseau intégré sur circuit de commutateurs commandés électriquement, tels que des MOSFET, à un circuit de traitement de signaux commandant le compteur. Les résistances établissent des réseaux diviseurs de tension variable compensant le compteur en phase, gain et erreurs de décalage réparties dans le circuit de traitement de signaux. On peut établir automatiquement les valeurs du réseau diviseur de tension variable pendant le test du compteur, à l'aide d'un ordinateur numérique, ou semi-automatiquement par l'intermédiaire d'un technicien, afin d'établir les états ''en circuit'' et ''hors circuit'' des divers transistors du réseau.

Inventor: STEPHENSON JOHN MICHAEL
IPC: H02K9/22
Filed: 1990-08-21
Abstract: An electric reluctance machine has a rotor 12 and a stator core 10 and a set of coils 18 embracing stator poles to energise them. In between the stator poles are spaces in which adjacent lengths of the embracing coils lie. Between adjacent coils sharing a common space the stator core is formed into a projection 22 extending radially towards the rotor. The projection increases the contact area between the coil and the stator. This has the effect of reducing the thermal resistance between the two. Consequently, the coil current can be increased, giving a greater maximum motor output. Furthermore, the overall stiffness of the stator core is increased by the presence of the projections.

Title: Lipid excipient for nasal delivery and topical application.
Inventor: WEINER ALAN L
IPC: A61K9/00
Filed: 1990-02-14
Abstract: Methods and compositions are described for liquid or gel forms of a lipid excipient to be used in pharmaceutical or cosmetic preparations. The lipid excipient comprises a phospholipid such as a lysophospholipid, for example, mono-oleoyl-phosphatidylethanolamine ("MOPE"). Relatively low concentrations of the lipid can be employed in forming the gel, e.g., about 1-2%. The invention discloses the use of a lipid delivery system at a relatively low lipid concentration as a non-toxic, non-irritating carrier or excipient alone or in combination with other agents, for both drugs and cosmetics. For example, the lipid excipient in sprayable or droppable form has special utility in the non-irritating delivery of peptides (e.g., calcitonin and insulin) to the nasal mucosa, due to the ability of the excipient to enhance absorption across nasal membranes. As a cosmetic, it can be used alone or in combination with biologically active agents.
