Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for producing laminated products, such as candy, is disclosed.  The method includes the steps of continuously forming a semifluid sheet of a first material on a longitudinally extending conveyor, depositing a semifluid second material on the sheet of the first material, continuously rolling the sheet from the edges thereof inwardly to form a double roll extending longitudinally along the conveyor, and flattening the roll into a laminated sheet product.  The method further includes the steps of forming the sheet into a "rope" of substantially smaller width than the sheet by folding the sheet over itself from the edges of the sheet and allowing the rope to move transverely across a slower moving conveyor so that the rope bunches up on the conveyor.  The rope is then flattened by a roller.  The method also includes the step of causing the sheet to longitudially fold over itself so as to form laminations.  Additionally, the method includes the steps of dividing the laminated sheet product into longitudinally extending strips and transversely dividing the strips into individual product pieces.  Apparatus for achieving the method is also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE       A reversible optical information recording medium which permits recording, reproducing, erasing and rewriting at high speeds by means of laser beams.  The reversible optical information recording medium has a recording thin film which is essentially constituted by Te-Au-O, and Ge or Se.  In the system which employs Ge, the recording thin film is formed by addition of at least one selected from a group consisting of Sn, In, Bi and Sb, such as to reduce the Au content in the film composition.          On the other hand, in the system which employs Se, a further improvement in the stability of the recorded signal is achievable by the addition of Ge, and an improvement in the recording/erasing sensitivities, parti-cularly erasing sensitivity, can be enhanced by addition of at least one element selected from a group consisting of Sn, In, Bi and Sb.  The recording/erasing mechanism in the reversible optical information recording medium of the invention mainly relies upon a change in the optical characteristic which in turn is caused mainly by a rever-sible phase change of Te.  The phase change in the recording medium of the invention can be effected by a laser beam of an extremely low light power density and short irradiation time as compared with that required by the conventional optical information recording medium.          This in turn permits much higher speed of recording and erasing of information over the conventional optical information recording medium.

Abstract: ABSTRACT           MACHINE FOR MAKING PAPER BOOKLETS      Apparatus  is  provided  in  which  booklets  of interleaved cigarette papers can be made from continuously moving strands of strip paper in which a cutting knife used to sever the paper strips precisely follows movement of the strip.  Movement of a driven input shaft (51) is brought onto the moving platform (25) and used to operate the cutting knife (29).  Paper from bobbins (10, 11) is converged by formers (15, 17, 18) and a spreader (16) into a strand advanced by nip rolls (21, 22) through cutting station (25).   The knife (29) in the station cuts a booklet from the strand while the station (25) moves with the strand.  A driven rotatory shaft (76) of non-circular section transmits its rotation to sleeve (81) that slides therealong as the station (25) reciprocates relative to shaft (76).  The sleeve (81) is operably connected e.g. by gearing or by a cam and follower to the knife (29) so that rotation thereof brings about the cutting movement.          (Figure 1 and 3)

Abstract: ABSTRACT   HOMOGENEOUS LOW MELTING TEMPERATURE BRAZING FILLER  METAL FOR JOINING FERROUS AND NON-FERROUS ALLOYS Most of the low melting brazing filler alloys for brazing of various steels and alloys in the range of 550°-850°C are silver-base.  These alloys (BAg-series according to the American Welding Society) contain from 30 to 93 wt% of silver and substantial amounts of melting temperature depressing elements like zinc and cadmium.  Both zinc and cadmium increase wettability and flow during brazing.  However, the presence of precious silver and carcinogenic cadmium in BAg-series alloys has always been a stimulus to develop new low-silver or silver and cadmium free alloys with brazing performance at least similar to those of BAg-series.     For these purposes, copper-base alloys particularly those derived from the Cu-Mn-Si system, seem to be a natural choice.  This system has a ternary eutectic with melting temperature in the vicinity of 800°C and it consists of elements which dissolve readily in both iron and copper.  Low melting temperature copper-base brazing filler metals, which have low silver concentration and are cadmium free, are disclosed here.  These filler metals contain (at%):0-10 silver, 4-16 manganese, 4-16 silicon, 0-20 zinc, 0-16 tin and 0-10 indium, the balance being copper and incidental impurities.  These alloys are produced in a homogeneous ductile, metastable foil shape or as a homogeneous metastable powder by rapid solidification processing.  A successful brazing is achieved for any combinations of steels, copper and its alloys, cemented carbides and various composite materials.

Abstract: SPECTACLES WITH FASTENING DEVICE ABSTRACT - This invention relates to spectacles in which the spectacle lens is connected to an individual component, for example a flange, by means of a fastening device.  In the spectacle lens  the two ends of a borehole are ex-panded into two borehole widenings which are engaged with a first protrusion on the flange and with a connecting element that is connected to a pin leading to the first protrusion.  In addition, the flange has two further protrusions supporting themselves on the border Or the spectacle lens, so that a four-point anchoring of the flange secured by the pin  against pulling and by the additional protrusions against rotating is furnished on the spectacle lens and vice versa.  A certain flange is suitable for given thicknesses and curvatures of the spectacle lens, because both on the front side and the back side of the spectacle lens it is not the front or back sides that define the gripping sur-faces for the connecting element and first protrusion, but the borehole wid-ening.

Abstract: ABSTRACT A dry sprinkler fire extinguishing system including a compressed gas pilot operated water valve between a water supply main and a dry sprinkler pipe, the valve having an input orifice connected to the water supply main, and a flow control disk which sets over the output orifice and is closed and held in a closed condition by water pressure from the water supply main.  The compressed gas pilot controls the flow of water from a chamber located above the flow control disk which is connected on its one side by a supply path from the water supply main.  When there is a preset minimum gas pressure in the dry sprinkler pipe, the pilot is held closed and blocks water flow out of the chamber, keeping the disk in a closed condition.  If the gas pressure in the dry sprinkler pipe drops below the preset minimum limit, the gas pilot opens permitting water to drain from the chamber faster than it can be replenished by the supply path from the water supply main, thereby permitting the flow control disk to open and flood the sprinkler piping.  Thus a dry sprinkler system is provided which eliminates the problems traditionally associated with dry sprinkler systems, including slow response times and false alarms due to "water hammer" in the water supply main.

Abstract: ABSTRACT:          A method and circuit employ digital techniques in processing an input signal of a first frequency to develop an output signal of a second frequency that is a multiple of the first frequency.  During each cycle of the input signal, a presettable down counter is decremented from its maximum value at a rate of 1/T1.  The digital word appearing at the output of the down counter at the end of the cycle is programmed into an up counter that is clocked at a rate of 1/T2.  The frequency of the signal developed at the overflow output of the up counter is divided by two by a flip-flop whose output provides a signal of a frequency which is T1/2T2 times that of the input signal.  The frequency of the output signal changes after one cycle of a change in frequency of the input signal.  The frequency multiplication factor can be a noninteger value.
