Title: Precious stone or diamond cutting machine - uses relative displacement cutter and stone with control effected by detecting resistance to cut
Inventor: BLONDEEL ERIC JOSEPH
IPC: B28D5/02
Filed: 1980-10-15
Abstract: The machine includes a stone-holder (14) and a cutter-holder (11) which are capable of relative displacement, utilising a motor or similar to effect the displacement and, thus, effect the cutting of the stone. Cutting is controlled by monitoring the resistance encountered by the cutter (10) in making contact with the stone (12), with the data collected being used to regulate cutting forces applied through the motor. Monitoring can be effected by direct detection of the resistance to cutting, by detecting a component of the resistance, or by detecting a related operational parameter. Detection may be applied to the force resisting the cutter feed, or to a related parameter, or to the resultant of a feed resistance vector and a cutting force vector.

Title: CCD picture scanning double photodiode lines - have alternate red and blue sensitive diodes in one line and green in other plus appropriate delay and demultiplex
Inventor: STEMME OTTO DIPL PHYS DR
IPC: H04N1/23
Filed: 1980-10-18
Abstract: The CCD bucket brigade scanner comprises two lines of the same length and containing the same number, 512, of photodiodes. The 512 green sensitive photodiodes match in proportion to their length the sensitivity of the red and blue sensitive diodes in their reduced length line the sum of red and blues equalling the total of greens. The spacing of the two separate line of sensitised photodiodes is related to the scanning rate and picture width and height of the video picture. The red and blue photodiode line supplies an analogue shift register and then into a delay line equal to one line scan period. The delay line feeds into a demultiplexer which separates the red and blue signals.

Title: Process for the packaging of material to be packaged
Inventor: LEUPOLDT FRANZ
IPC: B65D75/52
Filed: 1981-04-03
Abstract: Process for the packaging of material to be packaged, especially foodstuffs, in foils, in which, particularly in the case of a packaging in the form of tubular bags, the lateral portions are laid round to form at least one folding line, that is to say one bend. The folding line or the bend is to be located in front of the welding seam of the open ends, so that, during a subsequent heating of the packaging together with the material to be packaged, an internal pressure which is generated cannot act or can act only slightly on the welding seams. According to a preferred embodiment, more than one folding line or more than one bend can be provided in front of the respective welding seam, as seen from the material to be packaged, in the side portions of the packaging, with the result that there is little likelihood that an internal pressure which is generated will act on the welding seams during a preserving operation, for example heat treatment. <IMAGE>

Title: Drift conveyor for underground mining enterprises
Inventor: PAURAT FRIEDRICH WILHELM
IPC: B65G21/22
Filed: 1981-06-30
Abstract: The invention relates to a drift conveyor for underground mining enterprises. In its basic structure, the drift conveyer consists of a conveyor frame, traction means and a supporting means. The supporting means is designed as a conveyor belt and fixed to two traction means which for their part are guided via drives. The traction means are connected to the lengthwise edges of the supporting means. They are guided in or on guide rails of the conveyor frame arranged along the conveying path. The guide rails are guided, in areas equipped for the reception of conveyed material and if appropriate in straight sections of the conveying path, at a distance apart so that the supporting means suspended on the traction means forms an open conveyor trough. In curved sections of the conveying path, however, the guide rails are guided adjacently or virtually adjacently to each other so that the supporting means suspended on the traction means forms a closed or virtually closed conveyor pipe. In this manner, differences in travel for the traction means and hence for the lengthwise edges of the supporting means in curved sections of the conveying path are virtually avoided. Consequently, the drift conveyor can negotiate curves without problems, even in the case of curves with a small radius of curvature, the more so since the guide rails can also be arranged to lie one above the other in such curved sections. <IMAGE>

Title: Apparatus for measuring the surface tension using the stalagmometer principle
Inventor: LESSNIG WERNER
IPC: G01N13/02
Filed: 1981-07-01
Abstract: The apparatus essentially comprises a pipette (1) which contains a test volume (3) and has at its lower end a drainage surface (2). The drainage surface (2) is situated in a quasi-sealed drop chamber (7). The drop chamber (7) adjoins the stalagmometer pipette (1) above the drainage surface (2) and merges into an outlet tube (9) of narrower cross section at its lower end. In addition, a closable venting pipe (12) is mounted at the side. In this way, the surface tension is measured in an atmosphere which is saturated with the vapour of the sample liquid. This increases the reproducibility of the measurement and, in particular, substantially eliminates measurement errors due to evaporation in the case of readily volatile substances. <IMAGE>

Title: Arrangement for preheating feed water in a power station
Inventor: NGHIEM XUAN LUONG DR
IPC: F22D1/32
Filed: 1981-08-13
Abstract: The invention relates to an arrangement for preheating feed water in a power station with a power station boiler installation and a steam turbine installation. The steam turbine installation is provided with a large number n of removal points for bleed steam with the steam pressure pn as well as the saturation steam temperature Tn (pn<pn+1; Tn<Tn+1). The power station boiler installation has for each removal point a feed-water preheater which has a bleed-steam supply for the bleed steam pn, Tn of the assigned nth removal point. Arranged between an nth and an (n+1)th feed-water preheater is a supplementary feed-water preheater. This can be supplied, via a part-flow line with a pump branched off from the bleed-steam supply leading to the nth feed-water preheater, with bleed steam of the nth bleed point with a steam pressure pm which is raised in relation to pn and a temperature which is raised in relation to Tn (at pm<pn+1; Tm<Tn+1). Situated between such an nth and an (n+1)th feed-water preheater is according to the invention a large number of j, j>1, supplementary feed-water preheaters. These are connected in series with regard to the feed-water preheating. These j supplementary feed-water preheaters can all be provided with bleed steam of the nth bleed point via pumps in the form of mechanical compressors. The mechanical compressors are designed for a compression of the part flows in each case supplied to them to a temperature greater than Tn with stages of approximately (Tn+1-Tn)/(j+1), at corresponding pressures. <IMAGE>
Patent DE-3132253-A1 (DE)
Title: Arrangement for cancelling ghost signals in a television signal
Inventor: HOLMES DAVID DUNLAP
IPC: H04N5/21
Filed: 1981-08-14
Abstract: This arrangement contains a delay line (52) which receives at its input video signals which exhibit a component which can be used as control signal. The delay line imparts to the video signals a delay which, when a ghost signal is present, is essentially identical to the delay of the ghost version of the control signal compared with the control signal itself. Due to this delay, a delayed control signal appears at the output of the delay line at the same time as the ghost version of the control signal at the input of the delay line. The delayed signal from the output of the delay line is applied to a control amplifier (46) which is arranged with an amplitude comparator (42) and a sample-and-hold circuit (44) in a feedback loop (40). The amplitude comparator compares the delayed control signal with its ghost version at the input of the delay line and generates an error signal which indicates the amplitude differences between the two signals. The error signal is stored by the sample-and-hold circuit and used for developing a control signal for the control amplifier so that this amplifier generates a pseudo ghost signal which has the same amplitude and opposite plurality as the ghost version of the control signal during the sampling interval. The pseudo ghost signal is combined with the original video signal in order to generate an output signal which is free of ghost signals. <IMAGE>
