IPC: H05K7/20
Filed: 1990-01-26
Abstract: COOLING HEAD FOR INTEGRATED CIRCUIT                 ABSTRACT OF THE DISCLOSURE       A cooling head projected from an underside of a cooling plate (11), wherein a heat-conductive plate (17) is fixed on the free end of the cooling head and a nozzle (19) is fixed in the interior of the cooling head.  A cooling medium is fed to the heat-conductive plate (17) through the nozzle (19), to thereby circulate within the interior of the cooling head and quench heat generated by an integrated circuit element (4), by a heat exchange through the heat-conductive plate (17). An inwardly extending baffle (20a) is provided in the interior of the cooling head above the heat-conductive plate (17), to cover the peripheral area of the heat-conductive plate (17) so that a rising current of the cooling medium derived from a primary jet (S) fed from the nozzle (19) and impinging on the heat-conductive plate (17) is converted to vortices (W) circulating between the central area and the peripheral area of the heat-conductive plate (17).  According to this structure, the cooling efficiency of the cooling head is improved over the entire surface of the heat-conductive plate (17).

Title: Heat-sensitive recording paper
Inventor: OKUDA KATSUMI
IPC: B41M5/42
Filed: 1990-01-30
Abstract: A  heat-sensitive  recording  paper  comprising  a  sheet substrate, a heat-sensitive developing layer formed on the top surface of the sheet substrate that develops when heated, and a covering layer formed on the heat-sensitive developing layer which includes a pigment prepared by coating the surface of natural mica with at least one of titanium oxide and iron oxide.  The area of the heat-sensitive developing layer that develops appears in a colour different from that of the undeveloped heat-sensitive developing layer due to the regular multiple reflection of light which  takes  place  in  the  covering  layer.    Moreover,  the undeveloped part of the heat-sensitive developing layer has a pearl lustre which is also due to the regular multiple reflection of light in the covering layer.

Abstract: There  is  disclosed  an  improved  tamper-proof hanger having interchangeable shoulder cups.   The tamper proof hanger is provided with gripping arms which move in the vertical plane of  the hanger to clamp down on  the hanger arms.  The shoulder cups attach to the ends of the gripping arms, and a garment is secured to the hanger by clamping it between the shoulder cups and hanger arms.  A locking mechanism locks the gripping arms in the clamping position  and locks the hanger to a rod to prevent theft. The shoulder cups have a U-shaped cross-section and may slide onto the ends of the gripping arms by means of a tongue and groove arrangement.   They are lined on their underside  with  an  anti-slip  material.    This  material preferably consists of a rubber pad having a central band extending away from the bottom of the cup to leave a gap in between.  In this way, the band may conform to the size of the shoulders of the garnment being secured,  so that the garnment is best gripped and secured.

Title: Process for preparing polyarylene sulfides
Inventor: MIYOSHI AKIRA
IPC: C08G75/02
Filed: 1990-06-29
Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed is a process  for preparing a polyarylene sulfide, which involves polycondensing a dihalogenated aromatic compound with a source of sulfur in an organic polar solvent while  dehydrating  at  pressure  under  which  polycondensation is  performed.

Title: Beverage dispensing device
Inventor: TURNER CHARLES S
IPC: G07F13/02
Filed: 1990-07-20
Abstract: ABSTRACT   A  beverage  dispenser  (10)  includes  a  housing  (12)  for a pressurized beverage  container,  a  flow  meter (18) connected between the pressurized container  and  a  faucet (22).  A valve assembly (66,68,80) is attached to the   faucet   for   opening  and  closing  the  faucet  responsive  to  an electromechanical  actuator  (104,106,108).  A programmable controller (30) in  response  to  differential  pressure indicating signals produced by the flow  meter  determines  the  flow  rate  incrementally and the incremental quantities  are  accumulated  for  comparison with a preselected programmed quantity  for  pouring  a preselected quantity of the beverage and actuates the  electromechanical actuator for the time necessary to pour the selected amount  of beverage.  The flow meter includes a line segment (111) of known length,  size  and  material.    The  known  length  provides  a measurable pressure  difference owing to the drag therein as opposed to the measurable pressure  difference  obtained  from  the  head  of  a  manometer type flow meter.    Thus,  a  substantially larger difference pressure measurement is obtainable.    A  differential  pressure  transducer  (126) is connected to passageways  (124,126) connected to line segment ports (128,130) located at beginning  and ending points of the line segment for measuring the pressure differential  and outputting electrical signs indicative thereof for use by the  programmable controller in determining continuously during the pouring time  the  quantities  for a preselected amount of the beverage.  The valve assembly  includes  a  valve  stem  sleeve (82) attached between the faucet end.    The  sleeve  includes  at  the  end  adjacent  to the faucet a seal expander  (92)  for wiping clean the portion of the valve stem (96) exposed to  the  beverage  during  valve  opening.    This  prevents seepage of the beverage into the valve sleeve where it can solidify to stick the valve.

Abstract: DOWNHOLE ULTRASONIC TRANSIT-TIME FLOWMETERING MEANS AND METHOD                        (D#78,939 F) ABSTRACT OF THE DISCLOSURE           A  sonde  in a well  logging  system of the present invention includes caliper means providing a diameter signal corresponding to the diameter of a borehole traversing an earth formation.   First  and  second  transducers  which,  when  so controlled, transmit an ultrasonic acoustical pulse into fluid flowing in the borehole or provides an electrical pulse  in accordance with a received acoustical pulse from the fluid.  A control network controls both transducers so that during one part  of  a  measurement  the  first  transducer  transmits  an acoustical pulse into the fluid while the second transducer receives an acoustical pulse after it has passed through the fluid.   During  another part  of  the  measurement  the  second transducer is controlled to transmit an acoustical pulse into the fluid while the first transducer is controlled to receive the acoustical pulse after it has passed through the fluid and provides a signal in accordance with the received acoustical pulse.  A signal circuit connected to both transducers provides a travel time signal corresponding to the travel times of the acoustical  pulses  for  both  parts  of  the  measurement.   A conventional well logging cable carries control signals from the surface to the control network and the travel time signal and the diameter signal to surface electronics.  The surface electronics includes processing apparatus which provides the control signal to the cable and which derives the flow rate of the fluid flowing in the borehole in accordance with the travel time signal and the diameter signal.

Title: Method for introducing a treatment medium into the waste gas flow in combustion processes
Inventor: MARTIN JOHANNES J E
IPC: B01D53/34
Filed: 1990-10-24
Abstract: The method of supplying a treating agent to the exhaust gas stream in combustion processes provides for mixing a carrier medium with a treating agent, these media being brought before mixing to a pressure level necessary for atomization in a single-component nozzle. The ratio of the quantities of treating agent and carrier medium is infinitely adjustable and is adjusted as a function of the NOx gas concentration in the treated gas stream or as a function of the gas rate. The essential fact in this process is that a plurality of atomization nozzles are arranged in different planes and that the flame evolution in the firing space is monitored by flame detectors. When the flame front reaches the lowest nozzle plane, the feed of treating agent to these nozzles is shut off and the nozzles which are located above and in which there are as yet no flames, are controlled with respect to the throughput of treating agent as a function of the NOx gas concentration or of the exhaust gas rate. As soon as the flame front forms again in the region of the lowest nozzles, these atomization nozzles are fed again with treating agent. Even without treating agent, the lower atomization nozzles can be fed with carrier medium in order to cool the nozzles, if the carrier medium is water. <IMAGE>
