Abstract: ABSTRACT         The invention relates to a device for the cyclic rearrangement of a pile of substantially rectangular sheets, e.g. a pile of photographic prints.  It has a first and a second frame part which may be reciprocated relative to one another.  Upon reciprocation of the frame parts an individual sheet is removed from one end of the pile and added to the other end of the pile again.  For this purpose, there are provided (a) separating elements for separating the individual sheet from the pile, (b) feeding elements for feeding sheets to the separating elements, (c) a first retainer for holding the individual sheet in the first frame part and a second retainer for holding the remainder of the pile in the second frame part, and (d) guide elements for guiding the separated individual sheet for the purpose of returning it to the other end of the remainder of the pile.  The feeding elements on the first frame part include a contact face engaging under spring bias a transverse edge of the pile at the end from which a sheet is to be separated.  Upon withdrawal of the frame parts, a force is exerted by the pile to the contact face which yields against the spring bias in direction transverse to the reciprocation direction.

Abstract: ABSTRACT      A transaction system enables a portable token to co-operate with a fixed terminal.  The token is inductively coupled to the terminal, and receives data from the terminal via a frequency modulated carrier signal.          Data is sent from the token to the terminal by amplitude modulation of the carrier signal from the terminal, i.e. by modulating the power drawn by the token from the termimal.  The power needed to energise the on-board processing capability of the token is also obtained from the terminal via the inductive coupling.  The token includes an arrangement for commencing processor operation in an orderly manner when it is brought into the proximity of a terminal, and for providing an orderly shut down when the token is withdrawn.

Abstract: PROCESS OF MAKING SILICON, IRON AND FERROALLOYS          ABSTRACT     The  present  invention relates to the use of  self-reducing compacts  as  a  feed material for a  submerged  electric  arc furnace.  The compacts are comprised of finely-divided carbon-reducible  oxide materials,  such as,  the oxides of  silicon, iron, manganese, chromium or nickel, or mixtures thereof, and a carbonaceous source material.  The compacts may also contain a slag-forming additive.  The particle size of the components is less  than about  0.2  mm.     The  particles  are  mixed  in appropriate  weight ratios to yield the desired  product,  for example,  silicon, iron, or iron alloy.  Water is incorporated into  the  mixture  by alternately stirring  and  pressing  to produce  densified agglomerates.    Sufficient water is  added that  the  subsequent compaction step squeezes  out  at  least about  1%  of the incorporated water.   The  agglomerates  are compacted,  suitably  by means of double rolls,  which exert a maximum momentary pressure of from about 300 to about 4000  kg per linear cm of roll width, to form a compacted product.  The resultant  compacted product is eminently suited to use as  a feed material for a submerged arc furnace.

Abstract: DETERMINATION OF BEST FOCUS FOR STEP AND REPEAT            PROJECTION ALIGNERS                ABSTRACT OF THE DISCLOSURE      A reticle design is provided for step and repeat projection aligners which, when patterned on a wafer (10), allows quick macroscopic evaluation of best focus for used in fabricating integrated circuits.  The reticle pattern consists of opaque lines and spaces of widths slightly above the resolution limit of the resist/aligner system.     The macroscopic determination of best focus, being macroscopically visible,  eliminates the need for micro-scopic determination, thereby providing a quick and easy method.  The best focus determination is made by forming an array (22) of resist fields (14') on the wafer, sub-jecting each field to a different focus and exposure. Upon development, those fields away from the best focus and at the larger exposure doses will be removed, leaving a parabola  (24) of fields whose apex (26) is at high exposure.  Best focus is the focus setting used to print the row of fields (B) containing the apex.  The procedure may be used at different lens locations and reticle orien-tations to quantify lens aberrations and field tilt.     The method of the invention is also suitably used to qualitatively and quantitatively diagnose and characterize the lens, by printing full fields (34) with varying focus. In this manner,  lens astigmatism and curvature and field tilt can be mapped, measured, and understood.

Abstract: For efficient utilization of the capacity of a freezing tunnel it is desirable that the items for freezing 4 be introduced in close proximity but not so close, however, that they cannot be effectively frozen. It is usual for the items 4 to be delivered on a continuously moving belt 2 from an operations unit, in which they are deposited on the belt 2 at irregular intervals, and must be conveyed to a delivery belt 12, from whence after each row filling of this belt they are pushed off sideways in a row onto carrying trays on an underlying, transverse tunnel conveyor 14. According to the invention, the items are brought from the feeder belt 2 via a collecting belt 6 and an acceleration belt 8 to the delivery belt 12, and these belts are controlled in such a way that they produce spacings between the items, which due to the stopping of the belts during successive transfers from the delivery belt 12 are brought very close together, and that, by separate starting/stopping of the delivery belt 12 or both the acceleration belt and the delivery belt as a function of a detected excess distance between successive items, they produce separated items with a small interval between them. The items are fed without any significant queue pressure being built up underway. <IMAGE>

Abstract: The synthesis-gas plant is operated in a number of successive operating periods such that during the first operating period an excess of fresh water is supplied to the synthesis gas plant and the waste water from the resulting mixture is separated in a condenser and supplied to a storage container. During the subsequent operating periods, the waste water stored in the container is used as the feed water for the synthesis gas plant and the waste water obtained on each occasion is stored in the container with increasing deuterium concentration. The waste water obtained during the last operating period and having the highest deuterium concentration is used to feed a plant for producing heavy water. This process, when used in a synthesis gas plant for producing hydrogen, can be used to obtain deuterium-enriched water as a feedstock for a heavy-water plant without expensive additional energy-consuming devices.

Abstract: An apparatus for dispensing viscous pastes, creams and the like substances (12) that are not free-flowing under gravity comprises a container (10) and a charge-dispensing pump (120) at the bottom thereof. The pump comprises a cylinder (122) and a piston (130) consisting of an inner member (132) and an outer member (134). The piston (130) is reciprocated by a piston rod (126). In non-operated position, stem (133) of inner piston member (132) closes and seals a dispensing nozzle (146) at the outer end of the piston rod. When the piston rod is actuated downwardly, the nozzle (146) moves away from the stem (133) until shoulders (152) on the piston rod engage fins (148) on the stem and pull the inner piston member (132) down until it seats on the top of outer piston member (134) closing apertures (33) therein. Substance (12) is then expelled by piston (130) from cylinder (22) through outlet port (129) between the top of the piston rod and the inner member (132), the annular passage (152) through the piston and nozzle (146). When after dispensing the contents of the cylinder the piston rod is actuated upwardly nozzle (146) moves onto stem (133) and is thereby sealed, and port (129) closes. The inner piston member (132) is then lifted through outer piston member (134), opening apertures 33. A rib (27) on inner member (132) then entrains the outer member (134) and the piston (130) moves back to its non-operated position causing a vacuum in cylinder (122) which thus refills with substance (12) through apertures (33).
