Title: Conversion of penicillins and cephalosporins to 1-(s)-sulfoxides
Inventor: NIEUWENHUIS PAULUS G J
IPC: C07D499/04
Filed: 1990-09-27
Abstract: The present application discloses a process for the conversion of penicillin-1-(R)-sulfoxide(s) and/or cephalosporin-1-(R)-sulfoxides in solution, to their corresponding 1-(S)-sulfoxides comprising the step of treating said 1-(R)-sulfoxide with a sufficient amount of an acid anhydride to convert at least some of said 1-(R)-sulfoxide to its corresponding 1-(S)-sulfoxide. Also disclosed is a process for the production of 1-(S)-sulfoxide from penicillin and/or cephalosporin by oxidizing the penicillin or cephalosporin with an oxidizing agent and simultaneously or subsequently adding a sufficient amount of an acid anhydride to convert at least some 1-(R)-sulfoxide to its corresponding 1-(S)-sulfoxide over a time period of from 5 minutes to 2 hours so as to maintain the pH  above 3.5 and produce a solution of the corresponding 1-(S)-oxide.

Title: Process and device for the gasification of materials and/or for reforming a gas, plus a high-temperature heat-exchanger for carrying out the process
Inventor: MANOLESCU MIRCEA TUDOR
IPC: C10J/
Filed: 1991-09-10
Abstract: Abstract (Figure 1) PROCESS AND APPARATUS FOR GASIFYING GASIFICATION SUBSTANCES AND/OR FOR PERFORMING A GAS AND HIGH TEMPERATURE HEAT EXCHANGER FOR CARRYING OUT THIS PROCESS         The  invention  relates  to  a  process  and  an  apparatus  for gasifying liquid and/or fine grain solid gasification substances and/or for reforming a gas, using a gasification agent, in a reactor (1). In the process the process heat is supplied by heat collier particles which are heated within a substantially closed circuit in a heater (5) by combustion gases which are produced in a combustion chamber (3), and passed through the reactor (1) in counter-flow relationship with the gasification substance or the gas to be reformed and the gasification agent,  and then returned to the heater (5) for renewed heating. In accordance with the invention the particles and the combustion gas form a fluidised bed above at least one grid (34, 34a, 34b, 34c, 34d, 34e) arranged in the heater (5). The particles flow out of the heater (5) into  the  adjoining  combustion  chamber  (3)  in  which  they  form  a fluidised bed with the combustion gas and pass by way of a flow transfer pipe (7, 7') out of the combustion chamber (3) into an upper region of the reactor (1). m e throughput of particles through the flow transfer pipe (7,  7')  forms a seal which prevents a throughflow of product gas which is generated in the reactor (1). The particles form one or more fluidised beds in the reactor (1) with the gasification substance and/or the gas to be reformed.

Patent CA-2075686-A1 (CA)
Title: Stack type evaporator
Inventor: OKUDA NOBUYUKI
IPC: F25B39/02
Filed: 1992-08-10
Abstract: A stack type evaporator comprises tubular elements 1 each having a plurality of inwardly protruding recessed ribs 7 which extend from an upper header portion 1a of the element to a lower header portion 1b, with the ribs serving as straight drain canals 7a. A hydrophilic resin coating of a specific composition covers the outer surfaces of the tubular elements 1 and fins 2 each interposed between two adjacent tubular elements. The combination of straight drain canals with the specific hydrophilic resin coating is effective to facilitate the drainage of condensed water so that the waterdrops are perfectly prevented from flying out of the evaporator, and that any stinking mold or mildew is not permitted to grow within a reduced amount of remaining adherent water. Also, the hydrophilic coating itself does not emit any unpleasant smell which has been inevitable to the prior art water glass coating, thus an air-conditioned environment always remains comfortable.

Abstract: ABSTRACT    A flexible wound dressing and related method for the application thereof.  The dressing comprises a pad which contacts the wound without adhering thereto and absorbs wound exudate, a substrate adhered to the pad which is impermeable to both bacteria and liquid water, the substrate allowing the extent of wound exudate absorption by the pad to be observed therethrough, and   a cover sheet adhered to the substrate and having an opening therethrough, the substrate and pad being dimensioned such that they extend beyond the dimensions of the cover opening while allowing a portion of adhesive on the cover sheet to remain uncovered to permit the dressing to be adhered to a patient's skin around the wound and so no adhesive contacts the wound.  A method for the application of the aforedescribed dressing is also contemplated which comprises applying the dressing onto the wound.   38255.APP

Title: Multi room telephone transmitter
Inventor: LYNCH DAVID N
IPC: H04M11/04
Filed: 1992-11-10
Abstract: Abstract The invention is called, "Multi Room Telephone Transmitter". It allows the user to monitor a remote area, or several rooms in a building via the telephone line. It incorporate means for switching from one monitored room to the next, from the calling telephone.                              Specification Room monitors, or infinity transmitters as they are often called have been available to the public since the nineteen sixties. The only Canadian Patent, number 766,330 for an infinity transmitter was issued to a German designer on the 29/8/67, it enables a home owner, for example, to monitor his or her home from any where in the city, province, or globe through direct dialling. There are various electronic designs of infinity transmitters but their main function is the same, that is, to transmit audio from a monitored space, or room, via the telephone line, to the caller. A basic room monitor can be constructed with a ring detector, a timer, and a audio amplifier. The ring detector triggers the timer as soon as it detects the first ring signal. The timer activates an associate circuit to simulate an off hook condition. The audio amplifier then transmits audio from the monitored area to the telephone line. When the timer's time limit expires, (which could be a few seconds, or minutes) the monitor is deactivated, and the telephone line is restored to an on hook status. This type of monitor has several undesirable features in its design. It is activated by all telephone calls; determines the monitoring time limit; prone to false triggering, and like all other monitors on the market is only suitable for one room monitoring. There are other versions of one room transmitters that may have the following improvements in their design: (1) The ring detector amy be configured to be activated after several ring signals. This is desirable for the benefit of line connected devices such as call display, which require at least one ring signal before they can perform their function. (2) An access code may be required to activate the monitor. (3) After the access code has been decoded, a timer may be activated to control the monitoring time limit. Or preferably a latch circuit may be activated which will allow the caller to listen to the monitored area indefinitely. Deactivation occurs when the caller enters the off digit or replace the telephone receiver on hook.

Title: Method and apparatus for converting pressurized low continuous flow to high flow in pulses
Inventor: RUTTENBERG GIDEON
IPC: B05C11/10
Filed: 1990-09-10
Abstract: This invention relates to a device and method for converting low continuous flow to a high intermittent and pulsating flow arid is especially adapted for operating sprinklers, showerheads etc. at low flow. Fluid is introduced at a controlled low flow, such as by the use of a dripper (5, 24) in a supply line (7), into a container (1, 22) having expandable chamber (2). The outflow of li-quid from the chamber (2) is restricted until pressure created by the introduction of the liquid is sufficient to force the valve to open, and in response to a resistance to the flow, the fluid intermittently ejects at a higher flow. This is achieved by utilizing a preset pressure responsive valve (8, 28), designed for quick response, to create a water hammer effect. The invention describes pulsating valves and other devices operating in response to deformation created in elastic membranes in response to pressure changes.
