Abstract: CROSSOVER ARRANGEMENT FOR OPTICAL CONDUCTORS            Abstract of the Disclosure A crossover arrangement for optical conductors, each in the form of a rod of light-transmissive material, includes a multifaceted, e.g. polyhedral member having pairs of mutually parallel opposed facets.  Each pair of facets extend in a direction transverse, preferably perpendicular, to that in which a second pair of facets extend.  The end face of each optical conductor is abutted against one of the facets of the polyhedron.  Each facet has a coating of a material having a lower refractive index than that of the polyhedron or the optical conductors.  Light entering the polyhedron from one conductor passes across the polyhedron and into the opposite conductor, being constrained to stay within the polyhedron by the coatings on the side facets.  Preferably the polyhedron member is a cube and the optical conductors are of square cross-sectional shape.

Abstract: Abstract of the Disclosure A high-frequency heating apparatus includes an inner casing defining a heating chamber therein, and an outer casing surrounding the inner case.  A fixed wave-guide is fixed on a top wall of the inner casing to guide high-frequency waves fed from a magnetron to an excitation opening.  The waveguide has a step portion facing the excitation opening and located closer to the top wall than the other portion of the fixed waveguide.          A motor is mounted on the step portion and has a driving shaft extending through the excitation opening into the heating chamber.  A rotating waveguide, for diffusing the high-frequency waves delivered to the excitation opening and radiating the waves into the heating chamber, is disposed in the heating chamber and coupled to the driving shaft to be rotated thereby.

Title: Stirling-cycle, reciprocating, thermal machines

Granted: 1987-09-08
Abstract: ABSTRACT      Mechanical arrangements with primary application to single-acting, multiple-piston, Stirling-cycle machines pro-viding a dramatic reduction in mechanical complexity and production cost.  Two specific new machines are disclosed in detail, a single-acting, two-piston "ducted axle" machine and a quasi double-acting, four-piston, "drum cam" machine.  A power level control subsystem inherent in the ducted axle machine permits engine output to vary from maximum positive through zero to maximum negative under full load conditions by means of the simple rotation of a single moving part.  New thermodynamic working fluids are disclosed which have a higher dynamic heat transfer coefficient than either hydrogen or helium and are both chemically inert and easily liquefied.          A different power level control subsystem for Stirling-cycle prime movers based on the thermophysical properties of these fluids greatly simplifies changing the average system working pressure.  A new construction of the Stirling regenerator employs the anisotropic properties of materials such as pyro-lytic graphite to achieve superior performance.  Advantageous specific applications of copper matrix composites, manganese-copper alloys, and structural ceramics are disclosed.

Abstract: SUMMARY          The invention refers to a washing device for impression cylinders which is equipped with a roller-type washing brush extending over the entire width of the impression cylinder,  which  can  be  set  by  means  of  a  pneumatic setting  device  against  the  jacket  surface  of  the impression cylinder.  The washing brush can be sprayed with cleaning solution. It rotates at a higher speed than that  of  the  impression  cylinder.  Its  direction  of rotation is opposite to that of the impression cylinder. In  the  area  of  the  gripper  bridge of  the  impression cylinder, due to the flexibility of the pneumatic brush setting  device  and  in  conjunction  with  adjustment facilities,  the washing brush  can be  raised  from  the jacket surface of the cylinder. The washing procedure can be  initiated  automatically by means  of  an  electronic control system. The number of impression cylinders to be cleaned can be preselected.

Abstract: ABSTRACT OF THE DISCLOSURE            In this equipment the calls entered by means of call registering devices (4) at a main stop for desired destination floors are assigned to the next arriving or already present car, so that no doubts can arise  for passengers, whose calls had been acknowledged, in the choice of the correct car.  For this a locking circuit (28) is provided, which has the effect, that in presence of several cars at the main stop always only the doors of one elevator can be opened, where the  entered calls are assigned to this elevator.  The call registering devices (4) are blocked at a time dependent on the start of the door closure or after the entering of a certain number of calls, by means of an inhibiting circuit (25) and released again at the departure of the respective car.  During the retention cycle an indicator element, arranged in an indicator panel of the call re-gistering devices (4), signaling the blocking is activated.

Abstract: Abstract A pressure limiter and pump for use in a testing string.          The pressure limiter has an outer case and an inner mandrel which form an enclosure defining an annulus therebetween.          The inlet and outlet check valves in the annulus define a pumping chamber therebetween which opens toward the pump.          Fluid in the pumping chamber is never vented to the well annulus.  In a first embodiment, a transversely mounted pressure limiter piston provides communication between the pumping chamber and a lower portion of the testing string when actuated.  In the second and third embodiments, a pressure limiter piston is reciprocably disposed in the annulus between the case and mandrel; at a predetermined pressure differential, the pressure limiter piston recipro-cates such that the volume in the pumping chamber is increased.  A fourth embodiment simply uses a pumping chamber of predetermined volume such that the efficiency of the pump drops to essentially zero when the pressure in the pumping chamber reaches a predetermined level; no pressure limiter piston is used.

Abstract: In an item of workshop furniture 1 having a plurality of workstations 7, 8, which are separated by partitions 6, the workstations 7, 8 are fitted around a column 6 in such a way that the base area of each workstation 7, 8 on each of two sides is defined by one of the walls 6, the sides forming an angle with an apex in the column 2. This affords the facility for leading cables, pipes and hoses in the column 2 to provide connection points 12, 13 at all the workstations 7, 8. This provides great flexibility in creating or modifying multiple screened-off workstations 7, 8 each requiring multiple installations, it being merely necessary to set up or move one item of workshop furniture 1 in order to establish or move five workstations 7, 8, for example. The angular space together occupied by the workstations 7, 8 may be selected according to circumstances. It may therefore be 360 degrees, if the column 2 is free- standing, 180 degrees if the column 2 is fitted up against a wall; and 90 degrees if the column 2 is fitted in a right-angled corner. Over the workstations 7, 8, an extraction hood 4, through which all workstations 7, 8 of the furniture 1 can share a common extraction facility, may be fitted concentrically with the column 2. <IMAGE>

Abstract: The invention concerns a method and an arrangement for generating smoke for smoke treatment of foodstuffs. The smoke is developed by means of a technique in which combustion takes place from above, the smoke being used only when there is a charcoal layer of 0.5 to 100 mm on the fuel stack, which has arisen during combustion of the fuel. The charcoal layer acts as a regulator of the combustion air flow, the combustion being allowed to take place at a temperature which is advantageous as regards the development of odours and hazardous substances.
