Title: Strong shade-forming oxidn. hair-dye compsn. - contg. 4-hydroxy-indole or salt deriv. as coupler and standard developer
Inventor: KONRAD EUGEN
IPC: A61K8/49
Filed: 1980-08-22
Abstract: Oxidative hair-dye compsn. contains, as coupler, 0.01-4 (0.02-2) wt.% 4-hydroxy-indole, opt. as its salt with organic or inorganic bases or acids, in addn. to standard developers, opt. standard couplers, opt. other standard dye components and standard additives. An oxidising agent, esp. H2O2 is applied to the hair and left to act 10-45 min. at 15-50 deg.C. The hair is then rinsed, opt. washed and re-rinsed, and dried. 4-Hydroxy-indole and its derivs. are soluble in water, resist storage and cause less lipoid dissolution than 1-naphthol. Fast shades are obtd., ranging from blond via brown, ashen, purple, violet and blue to black, and including strong fashion-shades, e.g. glowing red and mahogany violet. The shades have higher strength and light-stability than those obtd. on using 1-naphthol as coupler.

Title: Panoramic dental diagnostic X=ray equipment - uses device to measure size of head, and give direct reading of voltage for radiation dosage required
Inventor: OHTA YUTAKA
IPC: A61B6/14
Filed: 1980-09-19
Abstract: Panoramic X-ray apparatus for dental diagnosis alters the intensity of the radiation to match the size of the patient's head. The degree of intensity is given by a device which measures the size of the patient's head (5). This device has an arm (1) with an extension (3) at right angles to it, carrying a slider (9) with another extension (4) projecting from it. The slider is moved along the arm until the two extensions are in contact with opposite sides of the head. This enables a reading to be taken from a scale with sections (2) spaced along it which directly indicate the voltage required, or in an alternative marking, the current required. The scale can be marked in staggered steps along the arm, across which the edge (10) of the slider passes, and can be transparent. An alternative design has a slider and a double scale so that both voltage and current can be read off.

Title: Road-sweeping machine
Inventor: SILVAN ECKHARD DIPL ING
IPC: E01H1/08
Filed: 1981-06-24
Abstract: The invention relates to the mounting of a change-over gear in a sweeping machine. By means of the solution according to the invention, a sweeping machine is produced, the special structure of which is with its drive system to a very great extent independent of the chassis. As a result, it is possible to mount the special structure easily and economically on the chassis of various manufacturers. The modification expenditure amounts only to the exchange of two universal joint shafts. Furthermore, the possibility of a technologically simple production sequence is created by the premounting of the drive system without chassis in a base frame.

Title: Supporting apparatus for the mould carrier of a plastics injection-moulding machine
Inventor: HEHL KARL
IPC: F16C33/50
Filed: 1981-10-14
Abstract: The supporting members (17) of the supporting apparatus, which can be adjusted vertically and laterally on a horizontal arm and a vertical arm, are each captured between the neighbouring rail (26) of the machine foot (25) by a receiving bearing (13) of the mould carrier (12).

Title: Method and machine for shaping a dough strand into a pretzel
Inventor: STRAUSS RAIMUND
IPC: A21C3/08
Filed: 1982-03-06
Abstract: A straight dough strand (10) is laid down on a holding body (30) which is curved in a semi-circular manner at the top, as a result of which the dough strand assumes a wave shape with strand ends (16) pointing away from one another. The strand ends are received between clamping jaw pairs (42) which are then moved towards one another so that the dough strand (10) is shaped into an  OMEGA -like shape. The clamping jaw arrangement (40) is then rotated through 360 DEG , as a result of which an entwinement (18) is achieved. Finally, the holding body (30) is pivoted forwards and simultaneously drawn back so that the transition sections (14) of the dough strand are displaced towards the rear side and the strand central part (12) towards the front side. The new method makes possible mechanical manufacture of pretzels. <IMAGE>

Filed: 1982-05-28
Abstract: A programmable logic array, constructed in emitter coupled logic technology, may be tested in its non-programmed condition. Diodes are located between all product terminal lines and first test terminals on the semiconductor chip as they are disposed between all sum term lines and a second test terminal. Furthermore, each input line of the sum matrix is respectively connected by way of a diode to the inverting output of a respective different input amplifier. When the sum matrix exhibits more input lines than there are input amplifiers, the connection is repeated cyclically. In this case, the sum matrix is divided into sub-matrices whose mutually corresponding sum term lines are linked by way of logic elements.

Title: Nuclear magnetic resonance spectroscopy method
Inventor: LEVITT MALCOLM HARRIS
IPC: G01R33/46
Filed: 1982-06-18
Abstract: In a method of heteronuclear decoupling in a pulsed nuclear magnetic resonance spectroscopy method operating at high resolution, an interfering nuclear species (e.g. protons) is irradiated by means of a number of composite pulses (R1, R2, R1, R2 etc.), each of which virtually inverts the longitudinal magnetisation, during the generation of signals originating from a nuclear species (e.g. carbon 13) to be observed. Two types of pulses (R1, R2 etc. and R1, R2 etc.) are used which have opposite high-frequency phases and the pulse series forms a repetitive train composed of 2<N> pulses of each type (where N is a positive integer), the pulse series having a form which is chosen in accordance with specific rules in order to ensure an effective decoupling. In a preferred form, the composite pulses are each composed of three individual pulses having a suitable duration, between which negligible intervals are present, the first and the third pulse having the same high-frequency phase, which differs from that of the second pulse by 90 DEG .
