Title: Doppler laser anemometric flow analysis system - uses rotating prism for scanning, with opto-electronic signal evaluation
Inventor: SCHNETTLER ARMIN DIPL ING
IPC: G01P5/26
Filed: 1980-03-12
Abstract: The measuring device rapid flow rate profile evaluation uses a rotating pism to provide deflection of the Doppler laser measuring vol. along a line through the measuring range of the measuring object e.g. an acetylene oxygem flame. The dispersed light from the measuring vol is fed via a lens and an aperture plate to an optoelectronic evaluation circuit. Pref. the latter has a Bragg cell which causes deflection of the laser light through an angle proportional to the measured value. The laser light is then fed through the rotating prism once again to obtain deflection in the perpendicular direction with the obtained profile recorded on a film or photomatrix. The device allows the flow rate profile to be recorded in a time of less than 1/600 sec.

Title: Conifer protection against beetles - by collared plastic sheath with pockets for fertiliser
Inventor: JONSSON GERTH
IPC: A01G13/10
Filed: 1980-04-16
Abstract: Plants, esp. pine plantations, are protected against wood boring insects and at the same time receive metered amounts of a fertiliser by a hose, made of plastic foil (polyethylene polystyrene). The sheath is made of two foil stampings, welded together on the sides and with a turnup at the top to form a protruding collar over which the beetles cannot crawl. The bottom of the hose is also turned up and perforated at the outside to form pockets for a certain amount of a granulated fertiliser. This prevents the drastic rise in timber loss due to beetles since the use of DTT has been banned. It saves the risky and more random method of scattering fertiliser from aircraft.

Title: Centrally controlled lighting installation for public buildings - has switches for individual lights allowing their operation independently of central switch
Inventor: CHRISTIANSEN DIETER
IPC: H05B39/04
Filed: 1980-08-01
Abstract: The lighting installation includes a normally-closed central switch (2) which can be opened against the action of a spring, to break the circuit to the lights (3,5,7). A first individual light switch (4) for the light (3) can be operated locally by an operating lever (12) in addition to being operable by attraction of a lever arm (11) by an electromagnet (11). If the central switch is opened briefly, the interruption of the magnetic field of the electromagnet causes the switch (4) to open due to gravitational force on the arm (11). Once the central switch is closed again, the switch contact (10) is opened so the switch (4) does not close again unless the lever (12) is used to close the contact (10). On the other hand, the switch (4) can be opened, even if the central switch is closed, by operating the operating lever (12) to pivot the arm (11) away from the electromagnet. A second individual switch (6) for lights (5) acts similarly to the first but uses an external lever arm (15) and a spring-urged normally-closed switch element (17) connected in series with the electromagnet (14).

Title: Welding bar for wide thermoplastics foil - has radial adjustments to welding blade for compensating thermal distortions
Inventor: SCHULZE EHRHART
IPC: B29C65/18
Filed: 1980-11-14
Abstract: A machine for producing transverse welded seams in two or more layers of thermoplastic foil comprises a rotatable support (sealing roller 1), in which a sealing blade is mounted. The roller applies the blade intermittently against a counter-support on the opposite side of the sheets. The blade is mounted in the roller by a number of radially adjustable straps or bars, located at intervals along the length of the roller and blade. Preferably, the roller contains inside it two parallel plates on either side of its axis, and the radially adjustable bars can slide radially by adjustment screws between these plates. In particular for the seal welding of thermoplastic sheets of great width, where the great distance between the end supports of the roller results in thermal and other deformations of the tip of the welding blade. The radially adjustable mountings enable individual adjustments to be made to the position of the welding tip along the length of the blade, so that an absolutely straight edge can be maintained.

Title: Escherichia coli hydride prodn. with enhanced mutation rates - by incorporation of a palindromic DNA sequence into plasmid or bacteriophage DNA
Inventor: COLLINS JOHN DR
IPC: C12N15/00
Filed: 1980-11-24
Abstract: In the prodn. of Escherichia coli mutants in which plasmid or bacteriophage DNA is produced contg. a transposone, (A) (i) the non-symmetrical region of the tranposone is completely exercised from the resulting tranposone-contg. DNA by means of a restriction endonuclease and (ii) the transposone ends of the resulting DNA are linked with a ligase and DNA is produced having a mirror-image symmetrical region, or (B) (i) by means of one or more restriction endonucleases, the non-symmetrical region of the transposone is completely excised from the transposone-contg. DNA and, in addition, either one DNA fragment with one of the two transposone ends is excised, the other transposone and remaining on the shortened plasmid or bacteriophage DNA, or two DNA fragments each comprising one of the transposone ends are excised and (ii) the resulting DNA fragment(s) comprising transposone ends are linked with a plasmid or bacteriophage DNA having two transposone ends with the aid of one or more ligases to produce DNA having a mirror-image symmetrical region (the plasmid or bacteriophage DNA with transposone ends having been produced by the procedure of step B(i); (C) the resulting DNA is transformed or transduced into Escherichia coli to form E.coli hybrids; and (D) the E. coli mutants formed as a consequence of the unstable DNA mirror-image symmetry in the E.coli hybrids are cultivated and selectively tested, individual mutants opt. being isolated. The procedure gives enhanced mutation rates (increasing the probability of obtaining useful mutants) because not only the mirror-image symmetrical region of the DNA but also neighbouring regions are rendered unstable by the mirror-image symmetry.

Title: Device for correcting the tool position on multi-spindle machine tools
Inventor: PREIS JOSEF DIPL ING
IPC: B23Q1/60
Filed: 1981-03-19
Abstract: In multi-spindle lathes in which several tool holders are arranged on a cross slide, the problem occurs that, during a cross slide adjustment for the purpose of correcting a tool, all the other tools will be adjusted along with this tool. This makes it necessary to provide guides and adjusting devices at the tool holders. In the invention, this adjustment of the tool carriers is effected by slides (2, 12) which are arranged on the cross slide between two components to be adjusted relative to one another and can be adjusted by motor. These slides (2) are each inserted in a positive-locking manner into a guide (3, 14) of the components to be adjusted. They have guide grooves (4, 15) in which in each case a guide strip (8, 13) of the component engages. The component does not guide the respective slide on the outside. The guide grooves and the outside guides of the slides (2, 12) are offset at an angle to one another. A relatively large displacement of the slides thereby leads to a small adjustment of the tool holder. <IMAGE>
