Title: A method and apparatus for unclogging clogged up conduits
IPC: B08B9/04
Filed: 1979-08-28
Abstract: A curved conduit 5 in concrete 6 is intended to receive pre-stress cables. It is clogged by a plug 6' of concrete. The problem is to remove the plug 6' without damaging the relatively fragile wall of the conduit 5. This is done in a cycle of three steps. In a first step a chain of articulated shafts 7 convey a rotary drive from a motor 1 to a tool holder including a cutting tool 3. The shafts and the tool holder are guided in the conduit by guide-discs 9 in which they are free to rotate. A short hole of relatively small diameter is drilled in the plug, the length and the diameter being chosen as a function of the curvature of the conduit and its inside diameter to avoid piercing the conduit wall. In a second step the ring of concrete around the hole is blasted away by a jet of water. In a third step the chain is advanced (and lengthened if necessary) and the cycle repeats. <IMAGE>

Title: Measurement of increase of bacteria
IPC: C12Q1/02
Filed: 1980-10-27
Abstract: The degree of increase of bacteria is detected as a change in oxidation-reduction potential of a liquid nutrient medium inoculated with bacteria. This change in potential is measured as a potential difference between a carbon electrode and a metallic electrode. Identification of the population and species of bacteria initially present in the liquid nutrient medium, the screening of bacteria present in samples, and investigation of the resistance of bacteria to medicines can be conducted on the basis of the time required until the potential difference changes markedly. Curves 2 and 3 of the drawing show the variation of the potential difference with respect to time. The abrupt rises in potential difference correspond to the concentration of bacteria reaching a certain level. <IMAGE>

Title: Semiconductor devices
IPC: H01L21/268
Filed: 1980-11-19
Abstract: A semiconductor device having one or more regions of reduced minority carrier lifetime is produced in a process in which a substrate of semiconductor material (1) having a transparent film (9) covering a high melting point material is irradiated with an intense radiant flux, either pulsed or continuous. The flux density and the duration of irradiation are selected so that the minority carrier lifetime of the semiconductor material (1) is reduced. The flux may be radiant energy from a laser source (5). The substrate material may be silicon or doped silicon material and the film may be of silicon dioxide or silicon nitride. The flux may be scanned over the substrate so that an extensive area may be irradiated; the scan may be continuous or stepped. Other regions of the substrate may be left uncovered by film (9) but irradiated to enhance the minority carrier lifetime in those regions. The process may be used to produce fast switched storage devices such as switched charge coupled device correlation or random access digital memory circuits, or for enabling production of MOS and bipolar components on a common chip. <IMAGE>

Patent GB-2076536-A (GB)
Title: Method of Detecting a Body of Liquid
IPC: G01F23/296
Filed: 1981-05-21
Abstract: A method of detecting the whereabouts of level I1 of liquid L in a container having a solid homogeneous wall 4 in which a less dense fluid is above the liquid. An ultrasonic signal is emitted into wall 4 from transducer Tx and is internally reflected at surface 2, at interface I3 between the wall and the less dense fluid and at interface I2 between the liquid and the wall. But since there is greater acoustic coupling at interface I2 some of the signal is emitted into the liquid. Thus the strength of the signal received at transducer Rx is a function of the extent of interface I2 between the transducers, which in turn is a function of the position of liquid level I1. Accordingly the strength of the acoustic signal received at Rx is a measure of the height of I1 above Rx. <IMAGE>

Patent GB-819881-A (GB)
Abstract: 819,881. Calculating-apparatus. ATVIDABERG-FACIT A.G. Dec. 12, 1956 [Dec. 13, 1955], No. 37995/56. Class 106 (1). In a cam-disc and pin-wheel calculating machine, the discs are set to positions spaced from zero positions by amounts proportional to the digits of a number to be entered but are initially in positions mid-way between the positions for the highest and lowest digits. Thus, the maximum movement necessary in the setting of the digits is reduced and the effort required in setting the different digits, especially by means of a single-bank keyboard, is less variable. The invention is applied to a tenkey machine in which the keys, in known manner, rock arm 14 clockwise or arm 15 counter-clockwise so that the ends of these arms engage slots 12 or 13 respectively in that camdisc 4 in setting position to rotate it varying amounts in one direction or the other. In the present machine, the discs are initially mid-way between the " 4 " and " 5 " positions as shown in Fig. 2, i.e. mid-way between " 0 " and " 9," each being located in that position by a detent pawl 17 carried by the associated pin-wheel and engaging a notch 20 in the cam-disc. They are set to this position by a pair of bails 29, 30 (see also Fig. 9), passing through arcuate slots in all the discs and moved apart by an arm 38. During the setting of a number, the complete actuator steps leftward across the machine and a rod 24 forming part of the rotary assembly enters teeth 25 of the set discs to lock them in set positions. In certain operations, e.g. division, when the rotor is to be moved to its leftmost position, it is desirable that the camdiscs may be set initially to " 0 " and, for this purpose, a partly toothed drum 26 is rotated and engages teeth 27 on each cam-disc which has not yet been set by the keys. These camdiscs are then held in the true " 0 " position by the engagement of their pawls 17 behind shoulders 28. Specification 351,276 is referred to.

Patent GB-2099994-A (GB)
Title: Determining coating thickness
IPC: G01B15/02
Filed: 1982-05-28
Abstract: The thickness of coating layers 1,3 deposited on both sides of paper, cardboard or equivalent material 2 is measured in the case in which both coating layers 1,3 contain the same component emitting characteristic fluorescent radiation. Typically both coating layers consist of the same material. Two functionally mutually independent radiation source/detector pairs are used, between which the coated paper or equivalent is passed. Excitation of fluorescent radiation is effected in both coating layers under measurement and the total intensity of the excited radiation present at each detector is measured. If the base weight of the paper or equivalent is known, the coating thickness is calculated from the results of the measurements obtained. The said base weight is preferably measured before applying the coating with the aid of a separate source of radiation and a transmission detector. <IMAGE>
