Title: Method to manufacture continuous timbers by dovetail jointing - supplies extra heat to boards before/after gluing, uses displaceable press section producing gluing pressure by friction
IPC: B27M3/00
Filed: 1992-03-24
Abstract: Warm timbers to be glued are moved from the drying chamber via the dovetailing machine, planed, cut to length, and fed via the glue supplier to the laminating press. If the boards are too cold, they may be heated by e.g. warm air, contact air, etc. The glue may also be heated. The press section is connected to an energy-supplying part. The counter stop is displaceable, while maintaining the gluing pressure. The press section may be switched on and off, and it produces the required gluing pressure by friction. The stop (2) remains in active position, until the boards have sufficient initial rigidity, so that press section (31) and boards do not deform. USE/ADVANTAGE - The method is used to produce glued laminated girders. Space-saving, easy and simple gluing without waiting periods.

Title: Remote measurement device of temp. and other physical parameters - has sensor units connected to central evaluation device via central signal highway enabling selective sensor unit operation
Inventor: HEIER-ZIMMER ANGELIKA
IPC: G08C19/24
Filed: 1992-03-30
Abstract: The measurement device has one or more sensors (3) connected in a combined unit to a central evaluation unit via a bidirectional signal bus (2) which also serves for voltage supply. The evaluation unit contains an encoder for producing a binary coded signal contg. at least two pulses as a synchronising signal for each sensor unit. Each sensor unit has a microprocessor (8) with temp-independent clock frequency which produces a time window of defined length in which the start pulse from a frequency divider (19) falls.  After a defined time it generates a second time window of defined length in which the stop pulse of the divider falls. ADVANTAGE - Enables multiple sensors of temp. and other physical parameters to be connected to a central evaluation unit via central signal highway enabling selective grouping and stimulation of sensor units to form measurement cycles.

Title: Dry and wet recovery of unconsolidated material - using floating and dry dredgers, and central conveyor, which is moved by face width
Inventor: WEHRSIG HARTMUT DR ING
IPC: E02F7/02
Filed: 1992-04-16

Title: Mutation detection in bio-polymers such as DNA and RNA with PCR - using specific, labelled primers, immobilising prods. after one cycle, adding enzyme-active antibodies and detecting primers by chemiluminescence
Inventor: SCHOENFELS CHRISTOPH
IPC: C12Q1/6858
Filed: 1992-04-18
Abstract: A method for direct qualitative and quantitative detection of mutations in biopolymers (e.g. NDA, RNA) is claimed comprising (i) prodn. of specifically lablelled prods. by an allele specific PCR (ii) sepg. (i) by solid phase techniques, (iii) incubating (ii) with enzymatically labelled antibodies (ABs), and (iv) detection of (iii) by chemiluminescence. Pref., the primer for the opposite strand is biotin-labelled and the mutant primer is labelled with fluorescein or vice versa. USE/ADVANTAGE - The method is more sensitive and cheaper than known methods (1 mutant can be detected in a pool of 1000 DNA probes). The PCR prods. from a reaction which is only specific for one allele are coupled to a solid phase and indirectly detected by the labelled primer. This is in contrast to prior art methods where PCR prods. are not detectable after the first PCR reaction.
Patent DE-4214067-A1 (DE)
Inventor: WANKO HEINRICH
IPC: G08G1/127
Filed: 1992-04-29
Abstract: Method for monitoring the transportation of goods to predetermined removal stations by means of transport vehicles within a spatially extended region, for example a state, with automatic determination of the distance travelled in each case and detection of this distance in an on-board computer. In a monitoring station, an individual route, containing removal stations, is stored as tour schedule with regard to the relevant route segments, travelling and standstill times for each transport vehicle in a central computer, which schedule is transmitted to the respective on-board computer, stored in it as nominal tour and compared with the actual values forming the actual tour, which are determined as actual route segments and actual times by means of the travel of the transport vehicle and a clock, a difference value being determined from the continuous comparison of the nominal values of the nominal tour with the actual values, which difference value, when a particular limit value is exceeded, conveys to the central computer via a radio data link between the transport vehicle and central station a limit value signal which contains the location established in the transport vehicle and the relevant time, whereupon the central computer, using the relevant tour schedule as a basis, modifies the latter into a replacement tour schedule and transmits it via the radio data link to the on-board computer, which replacement tour schedule is monitored with respect to nominal and actual values in the same manner as the original tour schedule. <IMAGE>
Patent DE-4215358-A1 (DE)
Inventor: BOUSACK HERBERT DR
IPC: G01N27/82
Filed: 1992-05-14
Abstract: The invention relates to a process and a device for the non-destructive testing of steel reinforcements in structures, especially to determine the position of individual prestressing reinforcements of unknown orientation and/or cracking in individual stressed reinforcements. The purpose of the invention is to provide a process and device of the aforementioned kind which makes it possible to determine with improved accuracy of measurement and sensitivity the position of steel reinforcements in structures and check for cracking in individual prestressed reinforcements in cases where individual prestressed reinforcements are fitted inside the structure with several others in a metal tube. This aim is achieved by a process in which a measuring head fitted with a pick-up coil detects a periodic change in field caused by the permeability of the steel reinforcement to be examined without any active previous magnetisation of the latter. The signal received at the measuring head is transmitted to a SQUID system behind which is connected an electronic evaluation system. Here, in the case of a stationary field, especially in the case of the natural remanent field of the steel reinforcement, the field alteration in time can be generated by the relative movement of the measuring head.

C, (c) in column C-3 the vapours from F-6, opt. with fatty acids vapours from a straight distn. C-6 and vapours from a unit arranged below this, are fed upwards in counter-current to condensate through a one- or two-stage reinforcement unit C-3/2 and C-3/1, (d) the vapours rising from C-3/2 and C-3/1 are washed in a condenser C-5, in countercurrent with condensate, and (e) the fatty acid stream taken off from the circulation-condensation stream of C-5 is treated by distillative purification, using stripping steam, in a stripper C-4 at 180-200 (190) deg. C, giving a fatty acid with purity above 99%. ADVANTAGE - The oil or fat recovered after the refining has less than 0.04% of residual fatty acid. Distribution of liq. over the cross-section of the falling-film distn. unit is uniform. Less steam is needed (0.224% in oil refining), reducing the operating costs.
