Title: Coupling and head-guiding foil for manual ultrasonic tests
IPC: G01N29/28
Filed: 1984-07-03
Abstract: From the point of view of physical parameters, ultrasonic testing is one of the methods that can be applied in the widest areas of non-destructive material testing. Manual ultrasonic testing of workpieces is, however, severely limited due to a range of factors. First and foremost, these are:     - the conditions of propagation of ultrasound,   - the reflection conditions of the sound ray at the flaws, - the coupling conditions of the sound generator or sound receiver,    - the indirect display of the echo pulses, and   - the high psychic and physical burden on the test personnel.   All these conditions reduce the usefulness, but in particular the reliability of the manual methods. The present invention is intended largely to eliminate these restrictions by a simple and reliable positive guidance of the test head, as well as to ease the coupling and keep it constant. The guidance, and thus also the positioning, of the test head can be carried out exactly by means of the coupling and guiding foil in such a way that it is also possible to evaluate the echo pulse displays statistically using simple means.

Patent DE-3427350-A1 (DE)
Title: Ring network for single-chip computers
Inventor: SCHWARZ SIEGFRIED
IPC: H04L12/433
Filed: 1984-07-25
Abstract: A single-chip computer with its serial transmitter, receiver can be coupled to a ring network by means of only one network driver in such a manner that the single-chip computer operates as local computer and interrupt-software controlled as network controller in accordance with the rules of the CSMA/CD and/or the token-passing method. Due to the directional data transmission in the ring network and the regeneration of the signals in each network driver, the transmission distance is increased and it becomes possible to use optical fibres. The network driver closes the network to form a ring and amplifies the signals when the single-chip computer is not transmitting or receiving. If the single-chip computer is transmitting or receiving, the network closes to form a ring over it. This switch-over in the network is utilised in the forwarding of the transmit authorisation in such a manner that only the next single-chip computer following, which is to transmit, receives the transmit authorisation.

Patent DE-3432484-A1 (DE)
Title: Grinding wheel
Inventor: KODANI TAKAHIDE
IPC: B24D3/06
Filed: 1984-09-04
Abstract: The grinding wheel according to the invention has a wheel body, a metal bonding layer and a layer of abrasive material in particle form. The wheel body has the form of a circular wheel and is produced from an electrically conductive synthetic resin or plastic. The metal bonding layer is deposited so as to be bonded fast to the outer annular surface of the wheel body, to be precise on one side of the latter, to be precise by using the customary electroplating process. Instead of the electroplating process, other processes may also be used to produce the metal bonding layer, such as the vacuum depositing process, the chemical plating process, the powder metallising process or the like. Typically, very fine diamond is used as the abrasive material. The grains or granules in the layer of abrasive material in granular form are fixed immovably to the metal bonding layer by a great part of the granules or grains being embedded in the metal bonding layer. A layer of granular abrasive material may be deposited on each of the two sides of the wheel body, to be precise depending on the area of application of the grinding wheel. In the middle part of the wheel body there is formed a through-hole, and a shaft extends through the hole in order to set the grinding wheel in rotation.

Title: Intake angle valve for controlling the stratified charge of the spark ignition engine
Inventor: BECKER ULRICH
IPC: F02B31/00
Filed: 1984-09-12
Abstract: The intake angle valve is built into the cylinder head in addition to the intake valve. The piston draws fresh air free of fuel through the intake angle valve and fuel-rich mixture through the intake valve. The intake angle valve comprises an angular mushroom valve with guide sleeve and rotary mechanism (Fig. 1), by means of which the intake angle valve, after opening, is turned about its shank axis. On closing, it is turned back into its starting position. The fresh air flows through the angular valve disc at a tangent into the cylinder and the mixture flows through the intake valve into the centre of the cylinder. A concentric stratification is produced by swirling of static mixture with rotating fresh air. The thermal stressing of cylinder wall and piston decreases and the energy dissipation by way of these parts is reduced to the benefit of the mechanically utilisable energy. Combustion occurs continuously from the centre of the combustion chamber outwards and reduces the wear even at high compression ratios. From the outset the formation of nitrogen oxides is reduced by this method of combustion. <IMAGE>

Patent DE-3444317-A1 (DE)
Title: Reactance switch
Inventor: RUOSS ERICH DIPL ING
IPC: H01H33/16
Filed: 1984-12-05
Abstract: The reactance switch has a switching point (for example 1) which is arranged between a high-voltage reactance (4) and a high-voltage line (3). The occurrence of flashback oscillations with unacceptably high voltage changes is intended to be prevented when this switch is being switched off, in a simple and reliable manner. This is achieved in that the switching point (for example 1) is connected in parallel with a voltage-dependent resistor (5). This resistor (for example 5), which preferably contains a metal oxide, such as zinc oxide, has a current/voltage characteristic which limits the returning voltage via the switching point (for example 1) in such a manner that the gradient of the voltage change of a high-frequency flashback oscillation occurring during a flashback of the switching point (for example 1) on the reactance (4) is always less than a limiting value.   <IMAGE>

Title: Method for the two-dimensional machining of workpieces with a tool, in particular for the form cutting of saw blades with a laser beam
Inventor: MUELLER ALFRED DIPL ING DR
IPC: B23K26/08
Filed: 1984-12-08
Abstract: In order to cut out workpieces (14) with the laser beam (12), which workpieces (14) can preferably be described in polar coordinates , it is proposed according to the invention to move the tool (11, 12, 13) in a linear axis and to rotate the workpiece (14) about an axis (18) of rotation, the form cut resulting through the simultaneous interaction of linear and rotary movement (17, 20). Advantageously only a small amount of space as well as half a stroke of the cutting machine are necessary due to the simultaneous interaction of linear and rotary movement. <IMAGE>
Patent DE-3503625-A1 (DE)
Title: Apparatus for metering bulk materials
Inventor: BUBENZER WILFRIED
IPC: G01F11/20
Filed: 1985-02-02
Abstract: Conventional apparatuses for metering bulk materials, especially foodstuffs, semi-luxuries and drugs, essentially comprise a supply container, a filling hopper and a metering chamber which can reciprocate between the outlet aperture of the supply container and the inlet aperture of the filling hopper and which meters out and transports the bulk materials. In this process, the metering chamber is moved in a linear fashion and as a result of this, the bulk material is subjected to considerable changes of direction and speed which encourage caking of the said material on the components. These disadvantages are eliminated according to the invention by arranging the metering chamber (1) on the free end of a pivot arm which is pivotable about a pivot spindle and by transporting the bulk material on a curved path. <IMAGE>
Patent DE-3506205-A1 (DE)
Title: Transport cart
IPC: B62B1/12
Filed: 1985-02-22
Abstract: The transport cart for the manual transport of objects comprises an undercarriage bow which serves at the same time as a carrier for a wheel set. On the undercarriage bow, at a medium height, a carrying bow, which forms the deposition surface for an object to be transported, is arranged such that it can be swivelled out of the undercarriage-bow plane. The carrying bow, for its part, is provided with a stand bow which can automatically be swivelled out by means of a scissors-type guide. On the undercarriage bow of the transport cart, on the side which is remote from the carrying bow, a roller support is arranged such that it can swivel out, the support bow of which is supported by means of a slotted rail against the undercarriage bow or the wheel bow arranged thereon and the wheels of the roller support, in the swivelled-in position of the roller support, lie in terms of position and diameter within the roller circumference of the wheels of the wheel set. A flat carrier is provided, which spans, on the one hand, the upper, free transverse strut of the undercarriage bow and, on the other hand, the outer, free transverse strut of the swivelled-out carrying bow, serves as a standing surface for an object to be transported and is provided with bearing bows which are supported on the two transverse struts, the bearing bows being of such a length that they compensate for the difference in height between the transverse struts when the transport cart is put down onto its two pairs of wheels.
Patent DE-3507488-A1 (DE)
Title: Hydraulic brake system
Inventor: BELART JUAN
IPC: B60T8/44
Filed: 1985-03-02
Abstract: In a hydraulic brake system with a master cylinder (30) coupled to the brake pedal (46) a hydraulic booster (31) with a booster piston (91) and a booster chamber (35) is provided, a servo pressure proportional to the foot force (F) being established in the booster chamber (35) during the braking process by way of a brake valve (6) actuated by the brake pedal (46). If the booster (31) is intact the servo pressure prevailing in the booster chamber (35) acts by way of a pressure line (85, 87) on the two-stage piston (20) of a filling stage cylinder (18), the small stage (95) of which immerses in a filling chamber (22) and in the braking process forces the pressure medium present in the filling chamber (22) by way of a pressure line (33) into the one brake line (37) connected to the working chamber (34) of the master cylinder (30). Should the booster fail, the two-stage piston (20) of the filling stage cylinder (18) remains in its starting position so that only the piston (92) of the master cylinder (30), moved by the brake pedal (46) by way of the actuating rod (11) and the piston rod (8), causes the pressure build-up in the two brake circuits (36, 37). <IMAGE>

Title: Internal combustion engine designed as (reciprocating or rotary) piston engine
Inventor: LEISTRITZ HANS KARL DR
IPC: F01N3/26
Filed: 1985-07-04
Abstract: The patent application bearing the title >>Internal combustion engine designed as (reciprocating or rotary) piston engine<< is an improvement of an exhaust process in which the extension of the charge cycle of the piston engine working process into a controlled double explosion for the purpose of high-grade emission control was briefly described. The present application proceeds from the application P3511941 of the same name and otherwise in the meantime developed prior art, especially our own applications P3516029.2 and P3522653.6, and on the basis of these develops the manifold design for multicylinder reciprocating piston and multiple disc rotary piston engines. In addition to the existing conversion of the individual piston travel discharge into a multiple jet unit by means of interposed spray tube bundles, this new development describes a method of conversion to be distinguished from this, which is termed compression divergence.
