Abstract: ENVIRONMENTALLY ACCEPTABLE PROCESS AND APPARATUS     FOR VENTILATION OF CONTINUOUS PAINT LINES           ABSTRACT OF THE DISCLOSURE      Organic    vapor    and   particulate   matter resulting  from spray painting in continuous painting lines  are  separately collected and disposed of in closed  painting system that permits access for touch up.      The  painting  line  typically  includes  an automatic  painting  booth, a touch up booth, a flash off  tunnel,  and  a curing oven, and a conveyer that conveys  objects  to  be  painted through the line in that   order.      The   automatic   painting   booth recirculates  air  through  a  filter and through the booth  to maintain proper painting conditions, and is tightly  closed  except  for  the  conveyer entrance. The  touch  up  booth  has  an  opening through which workers  have  access  to  the painted  objects and through  which  a  makeup  flow  of  air  is drawn to prevent   particulate   and  organic  compounds  from escaping.    The  make  up air flows to the automatic painting   booth.      A   portion  of  the  flow  of organic-laden  air  is  withdrawn  from the automatic painting  booth  to maintain the air within the booth at a safe organic concentration level, and burned.

Title: Felt turning roll
IPC: D21F1/40
Filed: 1990-09-12
Abstract: ABSTRACT OF THE DISCLOSURE    A felt turning roll for use in the dryer section of a papermaking machine has a stationary shaft extending outwardly from at least one end of a perforated roll shell.          The stationary shaft extends inwardly from the end of the roll for only a short distance which is substantially less than half the length of the face width of the roll.  The stationary shaft is bored to permit a source of sub-atmospheric air pressure to be applied to its exterior portion.  The inner portion of the shaft has a valve, a seal near its inner end between it and the roll shell, and openings to permit the exposure of sub-atmospheric air pressure within the roll shell on either side of the seal.          The use of short stationary shafts eliminates the center shaft which otherwise would extend for the length of the roll.  The roll therefore has a higher first natural frequency, and the use of the seal between the bored shaft and the interior wall of the roll shell permits the roll to apply a strong vacuum pressure beneath an annular area of the roll face near at least one end of the roll to facilitate threading of the papermaking machine during the start-up procedure.

Title: Everhot system
Inventor: REPPO UNO R
IPC: H05B3/36
Filed: 1991-01-18
Abstract: ABSTRACT      The purpose of this invention is to provide almost instant hot water at all hot water taps in a dwelling or any other building with running hot water.  To accomplish this, insulated metal foil tape of suitable thickness and width is applied onto hot water piping from central hot water tank to all hot water outlets.  The piping is then covered with insulation.  An appropriate amount of low voltage electric current supplied by a transformer is passed through the foil tape to generate enough heat to compensate for the heat loss through the insulation, therefore maintaining the temperature of the hot water in the piping from the hot water tank to the taps.  The metal piping can be used as a return path for the heating current.

Title: Process and apparatus for the manufacture of optical modules
Inventor: LAUPRETRE JEAN-JACQUES
IPC: G02B6/44
Filed: 1990-07-23
Abstract: DESCRIPTIVE ABSTRACT     For the continuous manufacture of optical modules incorporating optical fibres placed within ametal tube and embedded in a sealing product, the fibres (F) are introduced into a rectilinear guide tube (10) and the metal tube (T) is progressively formed around said guide tube from a tape or ribbon (R).  The metal tube is then welded along the joint line slightly upstream of the front end of the guide tube (10).  In order to permanently check the length ratio between the fibres and the metal tube in the thus obtained optical module, the fibres are introduced into the guide tube at a speed determined in real time on the basis of the measured values of the tensile force exerted on the welded tube, the speed of movement and the temperature of said tube. The sealing product (G) is injected into the welded tube slightly down-stream of the front end of the guide tube (10) at a controlled flow rate so as to ensure a complete and non-excessive filling of the metal tube.

Title: Control device for a passenger retaining and/or protective system for vehicles
Inventor: EIGLER JUERGEN
IPC: B60R21/00
Filed: 1990-02-19
Abstract: A control device for a passenger retaining and/or protective system for vehicleswith a sensor which generates an analog output signal corresponding to the acceleration or deceleration acting on its point of installation in the vehicle, an evaluation circuit assessing the sensor output signal and a triggering circuit which triggers the system when the threshold is exceeded. The time cycle of the sensoroutput signal is subjected to several different evaluations (1, 2, 3, 4, 5) in that said sensor output signal is taken to an evaluation circuit operating in a complex manner or to several such circuits operating differently, which assess the cycle according to differing criteria and thus with several differently defined thresholds. At least one of these evaluation circuits (2) is so constructed and operated that it can differentiate: between at least two different kinds of accident (frontal and oblique) with differently defined thresholds depending on the seriousness of the accident. At least one of the evaluation circuits (3, 4) is constructed and operated in such a way that it establishes the seriousness of the type of accident allocated to it from the events and the threshold allocated to it. The outputs of the evaluation circuits are connected to the inputs of an interlink component (23, 24, 234, 1234) which transmits the result to the triggering circuit. The interlink function is selected so that the system is triggered only if the evaluations indicate both a defined type of accident and the exceeding of the threshold(s) specifically allocated to the type of accident concerned.
