Title: Concave, convex safety razor
Inventor: HEGEMANN KENNETH J
IPC: B26B21/22
Filed: 1993-01-26
Abstract: A safety razor which conforms to both concave and convex body surfaces and has a handle (8) and a curved rotatable cartridge (2). Shaving blades (15) are positioned on both sides of the curved cartridge (2), thus, both concave and convex accurate cutting edges (11) are obtained in a single compact cartridge (2). The concave surface is used when shaving convex body surfaces. Rotating the cartridge (2) 180 degrees exposes the convex cutting surface for shaving concave body surfaces. The cartridge (2) is rotatably mounted to the handle (8) and is held in either concave or convex shaving positions with detents. When the alternate shaving position is desired, the cartridge (2) is rotated 180 degrees, either manually or remotely using a push button device (28) within the handle (8), which is also disclosed. The correct angular relationship of the handle (8) to the cutting surface of the cartridge (2) is set and maintained for both concave and convex settings by means of the detents since the amount of rotation between the two shaving settings is 180 degrees.

Abstract: A process for efficiently distributing processing between a mobile computing device having limited resources and at least one remote computing device having substantially greater resources than the mobile computing device, comprises establishing wireless communication between the mobile computing device and the remote computing device in response to a user's invoking of an application at the mobile device. The mobile computing device executes, in parallel, a first version of an algorithm for performing a function associated with the user-invoked application to obtain a first result, and the remote computing device executes a second version of an algorithm for performing the same function associated with the user-invoked application to obtain a second result. The results that are available first (generally the locally generated results) are presented to the invoked application on the mobile device. The application is thereafter updated with the most reliable results, which are determined by comparing the remotely-generated result with those locally generated at the mobile computing device and evaluating any difference therebetween.

Title: Amphoteric copolymer derived from vinylpyridine & acetoxystyrene
Inventor: BHATTACHARYA APURBA
IPC: C09K23/40
Filed: 1994-03-23
Abstract: A unique polymer was synthesized via copolymerization of vinylpyridine and acetoxystyrene under radical-initiated conditions followed by acidic or basic hydrolysis of the acetoxy group to afford the corresponding hydroxy group. The built-in acid-base dual functionality (phenolic and pyridyl units) in this polymer backbone gives rise to its unique solubility properties over a wide pH range in both aqueous and non-aqueous media. Due to its amphoteric nature, this polymer finds application as an anti-stat, viscosity modifier, and/or ion-exchange resin.

Title: Process for producing low-emission polyurethane moldings and composite bodies and their use
Inventor: HAAS PETER
IPC: C07C271/02
Filed: 1996-08-07
Abstract: A process is described for producing polyurethane moldings by the reaction of compounds of molecular weight 400 to 10,000 which contain at least 2 hydrogen atoms capable of reacting with isocyanates, and optionally chain extenders of molecular weight 32 to 399, with polyisocyanates, optionally in the presence of foaming agents, auxiliary materials and additives, in which defined carbamates are used as activators. The polyurethanes obtained by this process are particularly low in emissions, i.e. are stable in relation to diffusion and exhibit low fogging, and are thus particularly suitable for the production of composite bodies comprising a polyurethane core and at least one further plastic material as an outer layer. Also described is the use of these moldings and composite bodies which are stable in relation to diffusion and which cause low fogging, e.g. as dashboards or door trims in the construction of vehicles, furniture, machines or apparatus.

Inventor: JACOBSOHN DIETER
IPC: H04W88/18
Filed: 1996-11-06
Abstract: During data transmissions between a mobile radio network and a telecommunications network, in order to adapt the data signals to the protocols and modulation rates used by said networks, adaptation means, so-called interworkingfunctions are used which are either implemented in each mobile station of the mobile radio network, or which are implemented in a centralized interworking function that is connected to several mobile switching centers. A centralized interworking function (CIWF) is described for the simple construction of a mobile radio network, which contains different interworking functions (IWF1, ..., IWFn)for adapting data transmissions between several mobile switching centers (MSC) and different data transmission nodes (MOD, PH, PAD, ISDN) of a telecommunications network (PSTN), and contains a controlled switching network (SWT) which selectively connects the different interworking functions to the mobile switching centers. This technique provides a centralized installation in the mobile radio network, whereby each of the mobile switching centers has access toeach of the different interworking functions. In this way all the interworking functions need not to be repeatedly installed, but only as many as are needed for the average load of the available data services.
Patent CA-2190897-A1 (CA)
Inventor: GOLD DANNY
IPC: F16G11/10
Filed: 1996-11-21
Abstract: An article closure includes a crushable channel, a crushable portion, and a stretchable cord in the channel with a  protruding end.  A releasable closure restricts movement of the cord. Pressure on the end of the cord extends it, and moves a portion thereof  through the  closure.  Upon  release  the stretched portion of the cord within the channel crushes the channel as it contracts toward its unstretched length, thereby shortening the length of the channel and the crushable portion. On release of the closure, a portion of the cord moves back toward the channel and allows the channel and the portion of the article to which the channel is attached to return to their uncrushed dimensions.  Retaining straps hold the closure to the article proximate the opening in the channel so that the closure is restricted from moving away from the opening in the channel.

Abstract: Dispositif actionneur (20) à mouvement linéaire. Un premier mode de fonctionnement repose sur une technique de serrage selon laquelle un élément piézo-électrique est dilaté lentement, de telle manière qu'une force de blocage entre cet élément et sa base (38) le maintient en place. Ledit élément piézo-électrique est ensuite contracté très rapidement en taille, et l'inertie créée par ce mouvement dépasse la force de blocage et déplace l'élément par rapport à la base (38). Un second mode de fonctionnement repose sur une double technique de blocage selon laquelle l'arrière est d'abord bloqué et l'avant déplacé vers l'avant, et ensuite l'avant est bloqué et l'arrière déplacé vers l'avant. Tous ces modes de réalisation utilisent de préférence des matériaux semi-conducteurs, ce qui permet la formation de couches très minces et de petits dispositifs.
