Abstract: This invention relates to a cutting mechanism and its method of operation in "cutting side-lock" portions from "green state" roofing tiles. The tiles are manufactured in a conventional concrete roofing tile making plant in which mortar fed to a hopper extruder (18) of conventional design is formed as a continuous ribbon (26) on a series of pallets (P) conveyed beneath the hopper extruder (18). The ribbon (26) is thereafter cut by a knife (30) into discrete tiles (T) on said pallets (P) with a "side-lock" portion of each tile being blanked out by extension portions (32) (34) of the knife (30). The blanked out portions are thereafter removed from the remainder of the tiles by a blade 90 of removal means 14 such that no damage is caused to the tiles (T) and little or no detritus remains on the tile or the conveyors of the tile making plant.

Abstract: Computer timing apparatus enables two redundant strobe or clock elements (11, 12) to produce a single stream of timing pulses (CLK*), without interruption, when both elements are operating normally, and when one element fails. The apparatus incorporates a multi-stable stage (21, 22, 23, 24) and an output logic stage (25, 26, 27). The multi-stable stage detects state transitions in the input signals (CLK1, CLK2) of each clock element and generates a corresponding clock-tracking signal (TRACK1, TRACK2) which can disable the output of the corresponding clock from propagating through the output logic. The output logic stage logically combines each clock signal (CLK1 or CLK2) with its corresponding clock-tracking signal (TRACK1 or TRACK2), and logically combines the resultant signal to produce a single stream of output signals (CLK*) responsive to a next transition produced by either of the two strobe or clock elements.

Abstract: A sorption bed, arranged as a moving-bed reactor with or without circulating fluidised layers or as a fixed-bed reactor, is used for dry decontamination of waste gas or exhaust air by passing, in the temperature range between 30 and 130@C, acidic and/or oxidisable toxic gases contained in a waste gas having an oxygen content of at least 2% through sorbents introduced in the dry state. The toxic gases can be SOx, HCl, HF, NOx CO and hydrocarbons. The mean residence time of the sorbents is at least 20 minutes, generally several hours or days, and the mean particle size is at most 125  mu m. Fresh sorbent is supplied in an approximately stoichiometric amount, and used sorbent is removed correspondingly. The sorbents used are chiefly cooking soda and Ca(OH)2 or Mg(OH)2. Chlorides, fluorides, sulphate-sulphite mixtures and nitrate-nitrite mixtures, and mixtures of all the compounds mentioned occur in used sorbents. In particular, the carbonated reaction product from the low temperature range is reactivated by being returned to the combustion chamber of the combustion process, so that it can be used in a preliminary stage chiefly for desulphuration, dechlorination or defluorination. On account of its low temperature characteristics, the process can also be used for purification of exhaust air, in particular tunnel exhaust air, carbon monoxide and hydrocarbon being oxidised. The used sorbent is thus carbonated, so that in this case it is completely reusable for high-temperature decontamination of combustion chamber gases in a combustion chamber.

Inventor: KIM BYOUNG Y
IPC: G02B6/28
Filed: 1988-04-28
Abstract: A birefringent single-mode optical fiber (200) which propagates light into orthogonal polarization modes is subjected to a series of second order traveling flexural waves for propagation within the fiber (200). An acoustic wave generator (202) applies a periodic lateral squeezing force to the fiber (200), thus causing a second order flexural wave to propagate within the fiber (200). The wavelength of the second order flexural wave is selected to cause light propagating in one polarization mode to be coupled to the orthogonal polarization mode. The optical signal in the second orthogonal propagation mode has a frequency which is equal to either the sum of or the difference between the frequency of the optical signal in the first propagation mode and the frequency of the traveling flexural wave. The frequency of the optical signal in the second orthogonal propagation mode is shifted upward of or downward from the frequency of the optical signal in the first propagation mode as determined by the direction of propagation of the first optical signal with respect to the direction of propagation of the traveling flexural wave, and as also determined by whether the phase propagation velocity of the optical signal in the first propagation mode is greater or less than the propagation velocity of the optical signal in the second propagation mode. The centripetal couple of squeezing forces is preferably oriented at an angle of substantially 45° with respect to the axes of birefringence of the fiber (200).

Abstract: In a method for producing hollow articles from thermoplastic material, a tube-like preform is formed by discharge from a die gap of an extrusion head and inflated in a blow mould. Furthermore, the position of the preform with respect to the blow mould is adjusted by open-loop and/or closed-loop control and finally the flash produced by the blow mould is separated from the article once it has left the blow mould. 
<??>In order on the one hand to achieve a correct position of the preform in critical cross-sectional areas with respect to the blow mould and on the other hand to achieve a correct weight of the hollow article to be produced, it is proposed that for controlling the position of the preform in accumulator head operation the weight of the cut-off bottom flash and/or the net weight of the hollow article be measured and, depending on a weight discrepancy in comparison with a set value, that the die gap be altered, and in continuous extruder head operation that either the net weight of the hollow article and the weight of the bottom flash be measured and compared with set values or the net weight of the hollow article and the position of marks in relation to particularly critical cross-sectional areas be compared with predetermined set values and the positional control derived therefrom.

Abstract: The present invention comprises a carrier signal generating unit (101), a modulation signal generating unit (102), a mixing controlling unit (103,104) and a waveform outputting unit (105,106). In the present invention, the characteristics of the carrier signal from the carrier signal generating unit (101) is determined such that the musical sound waveform generated by the waveform outputting unit (105,106) is a sine wave or a cosine wave with a single frequency, where the mixing ratio of the modulation signal is made 0 by the mixing controlling unit (103,104). Therefore, the mixing controlling unit (103,104) presets the mixing ratio of the modulation signal to be 0, making it possible to generate a musical sound waveform comprising only a sine wave or a cosine wave of a single frequency. During the performance, the mixing ratio can, for example, be determined at a high value immediately after the start of sound generation and threrafter reduced to near 0 with time. Thereby, the frequency characteristics of the musical sound waveform can be controlled such that the musical sound waveform is changed from one comprising a lot of higher harmonics to one comprising only a single sine wave component or a single cosine wave component.
