Abstract: AUTOMATIC TEMPERATURE MEASURING CIRCUITRY     Abstract of the Disclosure An AC temperature measurement  circuit  utilizing a standard platinum resistance thermometer (SPRT) which is supplied with a constant current through a precision resistance.  The voltage across the SPRT is multiplied by a fixed gain by means of a high gain AC feedback amplifier.  The ratio of the output of the fixed gain AC feedback amplifier to the AC reference voltage across the precision reference resistance is effectively determined using a digital-to-analog (D/A) transformer.  The resistance value of the SPRT is then determined as a function of the reference resistance value, the value of the fixed gain, and the value of such ratio.  Appropriate means are provided to determine the temperature represented by the resistance value of the SPRT.

Abstract: ABSTRACT OF THE DISCLOSURE      The refresh  logic of a dynamic  MOS memory subsystem of  a  data  processing  system  is  tested  by  providing apparatus  for  counting refresh  cycles and  generating a counter   output  signal   in  a   first  state   after  a predetermined number of  refresh cycles.  A microprocessor periodically tests the state  of the counter output signal and  keeps  a count  of  the number  of times  the counter output  signal was tested  and  found to  be in  a second state.   When  the  microprocessor  tests  and  finds  the counter output signal in a first state, the microprocessor compares  the  number of  times  it tested  and  found the counter output signal in a  second state and determines if that  count is  within a  predetermined range  for correct operation.

Abstract: ABSTRACT          The present invention provides, without the drawbacks accompanied by the use of hot melt adhesives, an attractive, easily recycled labelled container, the label, on its underside that is adjacent the container when applied, being provided with a finite area on its leading edge and a finite area on its trailing edge, by applying thereto a solvent for the polymer in each of the finite areas, the finite areas comprising a viscous tacky solution of the polymer in the solvent, the solidifying solution being sufficient to tack and bond the label to container during wrapping.        After the label is wrapped around the container, the bond between the container and label becomes weaker as the solidifying solution hardens so that later the label can be easily and cleanly stripped from the container for recycling.

Abstract: ABSTRACT OF THE DISCLOSURE     A popcorn package for shipping and popping pop-corn is described.  The package includes a bag formed from flexible sheet material having a pair of face panels and infolded gussets extending between them.  Top and bottom seals extend transversely at the ends of the bag and a charge of popcorn and fat is positioned within the bag between the gussets and one of the panels which is placed on the floor of a microwave oven when the corn is to be popped within the bag.  Between the charge and the lower surface of the pakcage is bonded a flexible and foldable inductive microwave pickup sheet that can be composed of a plastic film upon  which a thin layer of metal has been deposited.  During heating the in-ductive microwave pickup sheet absorbs heat from the microwave energy and transfers it by conduction to the overlying charge of popcorn thereby increasing the volume of the popped corn.

Abstract: A B S T R A C T         Apparatus for the separation and feeding of sheets to a line printer and for the collection of the printed sheets.          A sheet separating unit is provided which is removably attached to a sub-frame which, in turn, is removably attached to the line printer to be used.  Rotation of the platen of the line printer is used to rotate the separating rollers of the sheet supply apparatus.  Feed rollers are supplied on the sub-frame which transport the printed sheet to a receiving compartment located directly behind the feed rollers.  The provision of a sub-frame has the advantage that the sheet separating and feeding unit can be used with various makes of office equipment without modification as long as the sub-frame is adapted to fit the particular unit under consideration.          The particular arrangement of feed rollers in the sub-frame results in simplified drive mechanism.

Abstract: ABSTRACT           Unexploded shells are dangerous in that the projectile ma be detonated by the wrong handling or even simply by moving it.  Compressed springs (16, 35) in the fuse mechanism which may be disturbed and trigger ignition are particularly dangerous.  The present invention provides a fuse mechanism which uses two primer capsules (12, 13) with one of the primer capsules being carried on a slide member.          The firing pin for the second capsule passes through an opening in the slide member so that if the slide member is only partially displaced detonation of a second capsule can, nevertheless, be achieved.  This results in the detonation of both primer capsules although the shell itself does not explode.  It is then left in a safer condition for disassembly.

Abstract: A high efficiency edge-emitting LED is disclosed in which optical radiation produced in an active layer of the device leaves the device without being substantially absorbed by the material comprising the active layer. The device is constructed so that an optical waveguide is formed such that light produced in the active layer either leaves the device without any reflections or with a maximum of one reflection. The thickness of the active layer and the compositions of the active layer and confining layers are chosen so that electrical carriers are confined in the active layer while light produced in the active layer is not confined therein.

Abstract: Abstract of the Disclosure A chimney sweeping device is disclosed.  The device includes a frame which is mounted on the flue at the top of the chimney.  The top section of the frame is enclosed on its three sides and top and has a pair of trap doors hingably mounted on its bottom side.  The bottom section of the frame consists of four angle iron legs, at least two of which are hingably mounted to the flue so that the frame may be tipped or tilted away from the top of the flue.  A chimney sweeping brush and a weight for pushing the brush down the chimney are provided and are suspended inside the frame via a central pulley mounted at the apex of the top section. Apparatus responsive to the position of the block and brush is provided to open and close the trap doors so that when the block and brush are raised to their highest-most storage position inside the top section of the frame, the trap doors are pulled up closed to seal the top section, and so that when the block and brush are lowered the trap doors drop open to permit their passage therethrough and on down into the chimney flue for cleaning.  The cable suspending the block and brush travels through a pulley system across the roof and down the side of the house to a winch system whereby a chimney sweeping operation may be accomplished from the ground.

Abstract: ABSTRACT OF THE DISCLOSURE The present invention relates to a process for the preparation of sulphur granules, in which in a granulation zone a sulphur melt is with the aid of at least one feeding device supplied in upward direction into a bed of sulphur nuclei, which are kept separate from each other and are contacted with a gas, the process being characterized in that a sulphur melt having a temperature of at least 5°C above the crystallization temperature is introduced into a bed of sulphur nuclei having a temperature of 30-70°C, which bed is fluidized with a gas, the melt, after having left the feeding device, being contacted with a powerful gas stream having a temperature about equal to the temperature of the melt and a velocity of at least 100 m/sec, in such an amount that the mass ratio of the gas stream to the sulphur melt is between 0.1 : 1 and 0.6 : 1, and the sulphur granules formed are continuously discharged from the granulation zone.  The process provides a more energy efficient production of sulphur granules having improved properties and reduces agglomeration of granules in the bed.
