Title: Masking with photo lacquer - uses second layer of photo lacquer with enlarged holes and reduced islands
Inventor: POTYKA SIEGFRID DIPL ING
IPC: G03F7/00
Filed: 1980-04-23
Abstract: In order to eliminate errors due to dust particles etc., it is usual to use two layers of photolacquer followed by masking. However precise alignment of the two masks is difficult, resulting in high reject rate. This problem is overcome by enlarging the holes and reducing the islands during the second masking process by an amount equal to the greatest possible mis-alignment. An error (6) in the photolacquer layer (3) is eliminated by the second layer (4). A hole (9) from the first masking is covered by the corresponding larger hole (10) from the second masking, allowing a misalignment (12). The pattern produced by the first masking is not affected.

Title: Fabric laying unit - has moving gripper to draw cut lengths on table and reduce moving mass (NL 9.12.80)
Inventor: PUIJENBROEK MARNIX JOSEF VAN
IPC: D06H7/02
Filed: 1980-06-03
Abstract: The equipment to lay out strips of textile, or other flexible material, has the support for the fabric beam, the fabric feed and cutter arranged as a flow line with the laying table. There is a reciprocating gripper mechanism moving over the table to draw the fabric strips along, by grasping one fabric edge. Between the cutter and the gripper, there is a pressure unit which moves away from the table after it. As only the gripper mechanism moves, the moving mass is reduced so that operating cycles can be accelerated, and the dimensions of the fabric beam can be increased.
Patent DE-3022917-A1 (DE)
Inventor: TANAKA YUTAKA
IPC: B23H7/04
Filed: 1980-06-19
Abstract: An error voltage (-Ee) which is an output signal of the comparator (46) is applied to an integrator (56). The comparator (46) is used for comparing a gap voltage (Eg) with a reference voltage (Eo). The integrated output signal is used as a table displacement speed signal (F). The integrator comprises an operational amplifier (58), an integrating resistor (60) and an integrating capacitor (62). The gap voltage (Eg) is controlled such that it is completely constant. For this reason, it is possible to eliminate the occurrence of a rise in the cutting-groove width caused by excess energy from the power supply (32). Electrical charge processing is possible with extremely high accuracy. <IMAGE>

Patent DE-3036766-A1 (DE)
IPC: C09J7/02
Filed: 1980-03-11
Abstract: The fluidic oscillator (14) includes a resonant fluid circuit having a fluid inertance and a dynamic fluid compliance. The inertance is a conduit (4) interconnecting two locations (16a, 16b) of a chamber on each side of a working fluid jet issuing into one end of the chamber (3), the inertance conduit transfers working fluid between the two locations. Through one or more output orifices (10), located at the opposite end of chamber (3), the fluid exits from an exit region (11) which is shaped to facilitate formation of a vortex (the dynamic compliance) from the entering fluid. The flow pattern in chamber (3), specially the vortex in exit region (11) provide flow aspiration on one side and surplus of flow on the opposite side of chamber (3), which effects accelerate and respectively decelerate the fluid in the inertance conduit (4) such as to cause reversal of the vortex after a time delay given by the inertance. The vortex in the exit region will cyclically alternate in velocity and direction of rotation to direct outflow through the output orifice such as to produce a cyclically repetitive side-to-side sweeping stream whose direction is determined, at any instant in time, as a function of the vectorial sum, at the output orifice, of the tangential vortex flow spin velocity vector and the static pressure vector and the dynamic pressure component, both directed radially from the vortex. By changing these parameters and by appropriately configuring the oscillator, sweep angle, oscillation frequency, distribution, outflow velocity, break up into droplets, etc. can be controlled over large ranges.

Patent DE-3106864-A1 (DE)
Title: Balancing pulse suppression circuit
Inventor: TAGUCHI SHINICHIRO
IPC: H04N5/10
Filed: 1981-02-24
Abstract: In the balancing pulse suppression circuit, circuits are provided to eliminate the equivalent pulses from the video signal. An assembled sync signal separated from a video signal is applied to an output gate circuit with an NAND element (18) so that only horizontal sync pulses are drawn out or removed. The gate control pulse applied to the gate circuit is formed as follows: clock pulses with a frequency of e.g. 175/4 fH (fH = horizontal sampling frequency of around 15734 kHz) are subjected by a frequency divider with D-flip-flops (FF1 to FF6) to a frequency division to form one signal with a frequency of 175/256 fH. A reset circuit with NAND elements (16, 17) processes the frequency-separated output signal, the delayed assembled sync signal from the shift register (15) and the inverted assembled sync signal which is emitted at the second output terminal of the gate circuit (14) on the input side in order to form pulses synchronised with the horizontal sync pulses. The pulses formed in this way effect the resetting of the frequency divider. In time with the pulse generation by the reset circuit, a circuit with a D-flip-flop (FF7) which generates a gate control pulse supplies pulses with a broader pulse width than those of horizontal pulses which in turn are applied as gate control pulses to the gate circuit on the output side. <IMAGE>

Title: Pillow with neck roll
Inventor: JAECKLE STEFAN
IPC: A47G9/10
Filed: 1981-09-26
Abstract: A pillow possesses a pillowcase in which are located at least one softer pillow part and a roll-shaped neck support which is somewhat harder by comparison with the latter. A characteristic feature is that the pillowcase has two separate compartments of different sizes, a roll-shaped neck support being located in the smaller compartment and a pillow part and a head support in the larger compartment. The result is the creation of a pillow which has three different regions, specifically a softer pillow part and relatively harder, substantially roll-shaped head and neck supports. The result achieved is that the entire cushion, in the position of use, has a soft, yielding base in the central region, that is to say in the pillow part, while in the region of the neck and in the upper end of the head a harder neck and head support, respectively, support the head and neck regions respectively in such a manner that the spine of the recumbent person is not undesirably angled or twisted.

Title: Process and device for hardening the inside of a two-ply steel pipe
Inventor: ESSER ALEXANDER
IPC: C21D9/08
Filed: 1981-10-15
Abstract: Two-ply steel pipes have hitherto been heated by means of disc-type burners on the inside and quenched by a circular shower following the disc-type burner at a short distance, so that the inner ply is hardened. The inaccuracies, caused by this application method, of the two pipe plies, in conjunction with the rapid heating by the disc-type burner, have the consequence that the inner ply does not uniformly bear against the outer ply. This results in a non-uniform hardness due to an irregular distribution of coarse grain and fine grain. In addition, cracks occur. The invention eliminates these disadvantages by heating the inner ply (2) slowly and uniformly by long burner strips (5) extending in the longitudinal direction of the steel pipe (1). As a result, the inner ply (2) adapts itself to the outer ply (3) by means of thermal expansion. Uniform heat transfer from the inner ply (2) to the outer ply (3) takes place. More uniform hardening without the risk of cracking is thus possible. In addition, the radial flanges (4) are not welded on until after hardening and after the cutting-off of the end sections of the steel pipe (1). <IMAGE>

Title: Pressure valve for a fuel injection pump
Inventor: KAWASE KOUICHI
IPC: F02B3/06
Filed: 1981-10-22
Abstract: This relates to a so-called pressure valve for a fuel injection pump, preferably for diesel. The closing element (7) has a collar (2a), which serves as so-called trunk piston and relieves the pressure line (to the injection valve) at the end of the injection process, in order to prevent trickling. This collar (2a) is provided with a first recess (c1), which extends parallel to the valve longitudinal axis (X), and with at least one second recess (c2), the cut surface of which, as shown, runs at an angle to this longitudinal axis. The outflow edge (2a') of the collar (2a) lies at least approximately in the same plane (a) as a corresponding outflow sealing edge of the guide recess (4a), when the closing element (7) is seated on the seating surface (4b) of the valve carrier (4). In this way an improved injection quantity characteristic is obtained at low speeds without the values being impaired at high speeds. <IMAGE>

Title: Method for detecting echoes in a noisy received signal and circuit arrangement for carrying out the method
Inventor: HELBERG HORST ING GRAD
IPC: G01S7/527
Filed: 1981-11-06
Abstract: A method for detecting echoes in a noisy acoustic received signal is specified in which the amplitude of the received signal is subjected to a threshold/time criterion and is detected on an echo when the criterion is met. For the purpose of reducing the error response rate in echo detection which, in particular, is due to reverberation, the rate of increase in the received signal amplitude is introduced as additional criterion for the echo detection. For this purpose, the received signal amplitude and/or the threshold is influenced in dependence in such a manner that rates of increase in the received signal amplitude which are less than a predetermined rate result in a reduction in the received signal amplitude and/or an increase in the threshold and the influencing of the received signal amplitude and/or threshold is essentially cancelled for the duration that this threshold is exceeded. A circuit arrangement relating to this is given.
