Title: Fluorination in tubular reactor system
Inventor: FALL DAVID J
IPC: B01J19/24
Filed: 1994-09-06
Abstract: FLUORINATION IN TUBULAR REACTOR SYSTEM                ABSTRACT OF THE DISCLOSURE Direct fluorination of organics such as 1,8-dichlorooctane in tubular reactor. Inert liquid containing organic feed is circulated through tubular reactor with fluorine gas for a time and at a temperature sufficient to yield fluorinated organic. Preferably, liquid and gas phases are separated from reactor product stream containing inert liquid, fluorinated organic, and any unreacted organic is recycled to turbulent mixing zone upstream of reactor in which fresh organic feed is added; and fluorine is added to recycle stream at end of mixing zone. Flow in tubular reactor is turbulent. Rate of organic feed and fluorine addition to process are independent of each other. Among process advantages are: Freon solvents not required; good control of reaction exotherm; and HF scavengers not required. Process useful for partial or complete fluorination.

Patent CA-2140029-A1 (CA)
Title: Method and apparatus for conveying a field of data in a communication system
Inventor: FELIX KENNETH A
IPC: H04B7/26
Filed: 1994-05-02
Abstract: A communication system (100) segments a field of data such that segments of data are transmitted in their own timeslot with their own control field. The communication system (100) segments the field of data into segments of data, adds control to the timeslot in a field designated for user information, and transmits the segmented data and control during the timeslots to a receiving unit. A receiving unit receives the timeslot, stores the segment of data representing a segment of the field, and recombines the segments to produce the field of data. If a retransmission is requested by a receiving unit, the transmitting unit need only retransmit the single timeslot containing the segment of data received in error. There is never a need to retransmit multiple timeslots since, in effect, each timeslot contains a discrete segment of the field of data.

Title: Respiratory mask and microphone mount for use therein
Inventor: BERLIN FLORENCE
IPC: A62B18/08
Filed: 1995-06-01
Abstract: Described is a respiratory mask (10) with an inner mask (22) for covering mouth and nose, wherein the inner mask (22) includes at least an inhalation valve (24), an exhalation valve (38) and a voice aperture (34) which is intended to be placed opposite the mouth. In the inner mask (22) a microphone mount (48) is removably attached above the voice aperture (34). On the inside of the microphone mount (48) two directional microphones (50, 52) are so attached that, when the respiratory mask (10) is put on, one of the microphones (50) is positioned opposite the mouth and is oriented substantially toward it and that the other microphone (52) is oriented substantially toward the inhalation valve (24). The directional pattern of the first microphone (50) is perpendicular and the directional pattern of the second microphone (52) is parallel to the inside of the microphone mount (48). The microphone mount (48) takes the form of a rigid printed circuit board and replaces the currently conventional voice diaphragm of the respiratory mask (10). In this manner there is obtained excellent voice reproduction and a reliable switching signal for voice activation, in order to turn on the voice communication only when speaking is actually taking place. Sealing problems due to a microphone connecting lead (16) which has to be led to the outside are avoided because it is preferably led through a voice channel (30) and a grille (32) which covers same.

Filed: 1993-12-13
Abstract: A cleaning composition contains (a) a detersive surfactant and (b) a poly(amino acid) compound or a precursor thereof, the said component (b) being protected from contact with a level of alkalinity as would cause degradation thereof. The component (b) may be stabilised by, for example, coating it with an organic acid compound or with a film-forming polymer; by agglomerating it with a controlled level of alkaline or alkaline-reacting compound (e.g. sodium carbonate); by spray-granulating it in admixture with a nonionic surfactant; by encapsulating it with a silicone-based resin; or by incorporating it in a composition that is non-alkaline. The storage stability of the compositions is thereby improved.

Title: Process for the manufacture of a profile part
Inventor: BUCHHOLZ HANS-VOLKER
IPC: B60J10/248
Filed: 1994-03-19
Abstract: A compound profile (43) consists of a fastening section (33) of a thermoplastic plastics material as well as profile sections (30,31) of elastomeric material, namely a profile section (30) of expanded rubber and a profile section (31) of soft rubber. All sections (30, 31, 33) are fixed to one another by co-extrusion and co-vulcanisation. The plastics material fastening section (33) assumes the function of the conventional metallic reinforcement of the compound profile (43). The compound profile (43) can be three-dimensionally shaped in that it is heated up to the plasticisation temperature of the fastening section (33), then is brought to the desired shape in a shaping tool, and in that shape is cooled until the fastening section (33) has again returned to its non-plastic state. One thus creates a profile part which is stable in shape.
