Patent NO-174002-C (NO)
Inventor: WOLF BERND MICHAEL
IPC: B01D1/00
Filed: 1990-02-12
Abstract: According to a process for recovering reusable gas from waste through pyrolysis, the previously comminuted waste is transformed into fluff, granulates or pellets and introduced into a degassing drum (16), in which low temperature carbonization gas is generated and separated from the residual matter. The low temperature carbonization gas is decomposed into combustion gas in a gas converter (19) and cleaned in a subsequent gas washing installation (21-24 and 47-51) with circulating washing water. Part of the water of the circulation system of washing water is withdrawn and replaced with fresh water in order to limit its concentration of toxic substances. The pyrolysis residues to be withdrawn from the low temperature carbonization drum are withdrawn through a water bath (72). At least part of the quantity of liquid withdrawn from the circulation system of washing water of the gas washing installation (21-24) is introduced in the water bath (72).

Abstract: ABSTRACT OF  THE DISCLOSURE    A spinal restraint device consisting of a rigid elongate primary  support  whereby  a  spine  of  a  patient  may  be supported.   The primary support has a top surface, a bottom surface, a first end, a second end and opposed sides.   The primary support has a head portion adjacent the first end and a back portion adjacent the second end.  The head portion is parallel to and lower than the back portion.  A pair of flaps are provided each of which has a first edge secured to the opposed sides of the back portion of the primary support and a second edge.  Buckles are secured to the flaps adjacent the second end.  The flaps are flexible and pliable such that the flaps conform to the contours of a patient's body without regard to the size and build of the patient when the second edges of the flaps are overlapped and secured in position by the buckles.  Pads are detachably secured to the head portion of the support such that the pads may be adjusted as required to  suit  the  longitudinal  and  angular  positioning  of  the patients head in relation to the head portion of the primary support and the elevation of the patient's head may be placed in a substantially anatomically neutral position.  Crotch and shoulder  straps  are  secured  to  the  flaps  to  secure  the patient  against  longitudinal  movement  in  relation  to  the primary support.

Abstract: A method of forming a multi-color image, comprising image elements in a first color which along at least part of their circumference adjoin image elements of one or more following colors wherein separation images in the first, second, third and any following color are each built up from image dot patterns of colored toner powder.      The separation images are transferred to an intermediate support to collect said separate images to form a multi-color image. The multi-color image is then transferred from the intermediate support to an image receiving material. The second and each following generated separation image is generated so that the image elements, which on transfer onto the intermediate support are required to adjoin image elements of a separation image already transferred thereto previously, at least partially overlap said previously transferred image elements. The transfer of the second and each following separation image to the intermediate support is effected by pressing the element which bears the separation image against the intermediate support with a force of no more than 1000 N per linear meter, whereby the intermediate support has a resilient surface. The invention also relates to apparatus for performing the method.

Title: Steering skis for snowmobiles and similar vehicles
Inventor: CAMPBELL NORMAN A
IPC: B62B17/02
Filed: 1990-10-24
Granted: 1994-11-15
Abstract: Steering skis for snowmobiles and similar vehicles. The ski has a lower surface for contacting the snow and at least one upwardly curved lateral edge in a region of the ski used for support of the vehicle.  The curved lateral edge defines a convex curved snow-engaging surface which merges smoothly with the lower surface of the ski.  The curved edge generates lift during turning of the ski while minimizing drag characteristics of the ski.  The ski is less likely to result in tipping during turns at high speed in deep snow, which improves the safety of the vehicle.  The curved edge produces minimal drag while turning and this allows for more use of the lift generated by the ski.

Title: Valved discharge mechanism of a refrigerant compressor
Inventor: TAKAHASHI HAREO
IPC: F04B39/10
Filed: 1991-01-09
Granted: 1996-05-14
Abstract: The present invention is directed to an improved valved dis-charge mechanism of a refrigerant compressor, The compressor includes a compressor housing having at least one chamber in which successive strokes of sucking, compressing, and discharging a refrig-erant gas is repeatedly performed. The chamber is linked to an out-side chamber through a conduit formed in the compressor housing. A valved discharge mechanism is disposed at one end opening of the conduit which opens to the outside chamber. The valved discharge mechanism includes a discharge reed valve which by means of a bend-ing movement blocks and opens the one end opening of the conduit. The discharge reed valve has a predetermined value of elastic modulus which allows the discharge reed valve to keep blocking the one end opening of the conduit until the pressure in the chamber reaches a predetermined value. A stopper member is disposed in the outside chamber to limit the bending movement of the discharge reed valve toward the direction in which the refrigerant gas leaves from the one end opening of the conduit. An auxiliary discharge reed valve having a small curvature is proximately disposed on the discharge reed valve opposite to the one end opening of the conduit so as to enhance the value of the elastic modulus  of the discharge reed valve while the discharge reed valve is bent in the direction in which the refrigerant gas leaves from the one end opening of the conduit.

Title: Fault detection method and apparatus
Inventor: ZULASKI JOHN A
IPC: H02H7/26
Filed: 1991-09-24
Granted: 2000-10-31
Abstract: Method and apparatus are provided responsive to the circuit parameters at one or more locations of an electrical power transmission and/or distribution network for detecting protective device operation. The detection of the protective device operation is utilized to locate faults and also to ascertain the status of protective devices. This information is useful in automated power systems for desirable isolation and sectionalizing of faults for optimum restoration of the network. A fault detection unit of the present invention is responsive to sensed circuit parameters and provides at least first and second outputs indicative of protective device operations that open the circuit. The first output is provided upon the occurrence of an overcurrent followed by the loss of a circuit parameter, such as voltage, for a specified time duration. In a preferred arrangement, the timing for a specified time duration is started when the overcurrent ends. Thus, rapid detection is achieved since the specified time duration need not include the maximum operating time of the protective device. The second output is provided if the conditions for the first output are satisfied and the loss of the circuit parameter continues for a specified extended time interval corresponding to the sequence of operation of the upstream protective device so as to establish protective device operation.  For example, the first output in one illustrative arrangement corresponds to the opening of a recloser while the second output corresponds to the lockout of the recloser. In a preferred arrangement, a third output is provided upon the occurrence of an overcurrent for a specified time duration. A fourth output is provided upon the occurrence of an overcurrent for a specified time duration and the presence of voltage after the occurrence of the first output for purposes of detecting downstream fuse operation on power systems utilizing fuse-saving arrangements.
