Title: Separating photoconductive layer from carrier - directing water jet at high pressure at one end
Inventor: TIETZE WOLFGANG ING GRAD
IPC: G03G13/00
Filed: 1979-03-30
Abstract: A water jet is ejected under high pressure from a jet onto a photo-conductive layer to separate it from its carrier. By this method a photo-conductive layer based on selenium is quickly and simply removed from a metallic support. Neither is smeared or otherwise affected so that they can be used again as a layer support and photo-conductor for an electro-photographic recording material without further cleaning or processing. The jet can be directed vertically or at an angle less than 90 degress, pref. 50 degress. A valve in the water circuit opens as soon as the jet (2) reaches the edge of the drum (5). A high pressure jet (7) is then directed onto the rotating drum, the power deriving from a high pressure pump (12) outside the container (1). The valve is closed again when the jet reaches the end proper of the drum.

Patent DE-2928069-A1 (DE)
Title: Arc welding process - involves vibrating the free end of a consumable electrode, within the space between two metal workpieces to be welded
Inventor: ROEN RICHARD ALAN
IPC: B23K9/30
Filed: 1979-07-11
Abstract: A weld is formed in a space between the walls of two metal pieces to be welded, the process involving moving a consumable electrode in a torch and subsequently into the space while the two workpieces and the welding torch are moved relative to each other so that the torch is moved along or reciprocated within the space. A sufficiently high voltage is applied between the workpieces and the consumable electrode to form an arc to melt the electrode and at least a portion of the walls of the workpieces, the electrode reciprocating across the space. The reciprocation frequency is >=6H2, during welding, the free end of the electrode is located within the space while at the ends of each reciprocating cycle of the electrode, an impact force is applied to interrupt the electrode movement towards the wall in the direction of which it has moved before the application of the force and immediately after the application of the impact force, the electrode is moved away from the wall to approach the opposite wall so that the molten metal at the free end of the electrode is projected against the wall. The process is suitable for use in nuclear reactor pipes since the weld obtd. is spread out and the penetration is not excessively deep. The process is advantageous for surface hardening since penetration is slight.

Title: Expanding winding-reel for yarn balls - has outer sleeve with serrated end and inwardly-projecting pins
Inventor: OBST INGO
IPC: B65H75/24
Filed: 1979-09-08
Abstract: An expanding reel for automatic winding of balls of yarn has a spindle sleeve with a serrated end and inwardly-projecting pins which hold the yarn end during doffing. The serrations comprise an odd number of teeth, whereby each is diametrically opposite an inter-tooth gap. The pins extend radially from the tips of the teeth almost to the centre of the sleeve. The reel is opened and closed by longitudinal movement of an axial rod to which the inner reel arms are affixed. The middle reel arms have a cranked end to avoid trapping yarn when the reel is folded. The reel is simple and inexpensive to construct, and ensures tucking-in of the yarn end to the centre of the ball during doffing without the use of additional complicated mechanisms, and without any projecting parts to hinder the doffing process.
Patent DE-2940200-A1 (DE)
Inventor: WITTMER MARC DR
IPC: H01L23/482
Filed: 1979-10-04
Abstract: If the known contact arrangements for semiconductor components are heated to a relatively high temperature for a prolonged period during manufacture or while in use, the electrical resistance increases and the outer metal layer or layers becomes/become brittle, which reduces the mechanical strength. The reason for this is the diffusion of silicon into the metal layer or layers from the semiconductor body. To prevent this diffusion, a layer (13) is proposed which is effective as a diffusion barrier for silicon and which is situated between the semiconductor body (10) or the first layer (12) of the contact arrangement and the outer metal layer (14). This diffusion barrier is composed of the boride, carbide or nitride of a transition metal from one of the groups IVb, Vb or VIb of the periodic system of the elements. It has been shown that this layer prevents the diffusion of silicon even at those temperatures which are far above the temperatures necessary during the manufacture of the semiconductor component. <IMAGE>

Title: Noise suppression circuit for VHF stereo radio receiver - controls audio cross-talk attenuation according to amplitude of HF carrier and of LF signal
Inventor: HANSEN JENS DIPL ING
IPC: H04B1/16
Filed: 1979-11-29
Abstract: The noise suppression circuit has stages (8-11) to vary the crosstalk attenuation between the two sound channels in accordance with the magnitude of the LF signal taken from the FM demodulator (3). The crosstalk attenuation is reduced as the LF signal reduces in amplitude. The normal control signal for the cross talk attenuation is obtained from the HF carrier amplitude and passed to the stereo decoder (4) via an amplifier (8). The amplifier's gain is controlled by a voltage obtained from the FM demodulator (3) via a rectifier (9).

Title: Photothermoplastic recording process giving half tone picture - uses photoconductor and thermoplastic layer, which are heated, charged, exposed and cooled
Inventor: PANASJUK LEV M
IPC: G03G16/00
Filed: 1980-03-29
Abstract: Photothermoplastic recording process for optical information uses an information carrier with a semiconductor sensitive to actinic radiation and a thermoplastic storage layer. The process involves charging, exposure, thermal development and cooling of the carrier to fix a visible image. The thermoplastic layer is preheated to a temp. between its Tg and flow temp., which is maintained until the end of thermal development, then the carrier is charged to potentials ensuring an electric field strength producing pondermotive forces in the thermoplastic layer ca. 5-10% below the shear modulus of this material at the recording temp. At the same time, the optical information is exposed at a strength of illumination which changes the resistance of the semiconductor layer by 10-15 times at the points with max. exposure. The charging and exposure times are determined from the formula ts=tm(tau)(In k)/(k-1) (in which ts is the charging time and tm the exposure time. tau is the dark relaxation time for a charge on a carrier. k is a multiple of a photosignal on a semiconductor layer at a max. exposure point). Half tone pictures can be produced without special rastering with a great signal-to-noise ratio for small exposure times.

Title: Adjusting eddy current test equipment - using calibration piece and conductivity reference trace on storage oscilloscope screen
Inventor: WAHODE PETER DIPL ING
IPC: G01N27/90
Filed: 1980-08-07
Abstract: A method of adjusting eddy current test equipment enables the test object positioning problems due to eddy circuit heating, and consequent expansion, to be overcome. A test-piece is first passed through the test coil. This test-piece has two adjacent conductivity monialies, one of which has an additional material deficiency, e.g. a small drilled hole. As a result reference points corresp. to points outside the conductivity and dimension tolerance range are included in the oscilloscope trace. The imaginary line joining the points corresp. to the dimensional direction in the impedance plane. The trace image is rotated until the joining line is parallel to one axis of the c.r.t. The conductivity is then easily read from the distances of subsequent traces from the stored line. This method is suitable for testing containers and pipelines, e.g. in heat exchangers used in nuclear reactors.

Title: Electromagnetic pump with built-in EM valve - has pump actuating coil and valve operating coil with magnetic paths sepd. from each other by non-magnetic portion
Inventor: TOYODA AKIRA
IPC: F04B17/04
Filed: 1980-09-23
Abstract: The electromagnetic pump includes an electromagnetic plunger actuating electromagnetic coil (4) and an electromagnetic valve operating electromagnetic coil (5) disposed coaxially in adjacent relationship and having magnetic paths of their own separated from each other by a non-magnetic portion, to obtain a desired magnetic flux distribution. The two electromagnetic coils have the same direction of windings to obtain an improved magnetic flux distribution, providing improved pump operation. By passing a half-wave rectified current or a pulse current of a predetermined cycle to the two electromagnetic coils connected in series with each other, a magnetic flud can be produced in each electromagnetic coil and made to flow in the magnetic path exclusive to each electromagnetic coil, so that mutual interference of the magnetic fluxes produced by the two electromagnetic coils can be avoided.
