Title: Simple transistor drive for signal coupling transistor switch - consists of transistor pair with each transistor of opposite conductivity type (OE 15.10.77)
Inventor: MUEHLMANN ERNST
IPC: H03K17/04
Filed: 1977-08-29
Abstract: A simple transistor drive or control circuit for a signal coupling transistor switch is used. It consists of a PNP NPN transistor pair which allows rapid switching and consists basically of a single transistor amplifier. A PNP-NPN transistor pair (T2, T2') is connected between a signal input (E) and output (A) via capacitances (CE, CA), and the bases of the transistors are connected to the collector and base of the control transistor (T1). The biassing is dependent on an array of transistors, while an input switching waveform is applied to the base of the control transistor via a further resistance (R1).

Title: DC motor drive for diesel electric ship - has transformer between AC supply and rectifier whose windings can be switched at low speeds for high efficiency (NL 2.3.79)
Inventor: HOELZENBEIN GOTTFRIED DIPL ING
IPC: H02P7/293
Filed: 1977-08-31
Abstract: The DC motor driven ship has the motor speed controlled by a rectifier with thyristors and commutating chokes. Diesel or gas turbine engines drive alternators. In order to achieve an optimum efficiency at low motor speed a transformer is connected between the controlled rectifier and the a.c. supply. The primary and or secondary of the transformer is switched or shorted for the lower speeds. The system uses the full capacity of the rectifiers even at low motor speeds so that cable runs can be kept to an optimum thickness and an efficient performance assured. The transformer switching reduces the voltage applied to the rectifiers and increases the commutation reactance.

Title: Twin column elevating platform - has driven screw in one column with tensioned chain in other and spring loaded brake operated on chain breakage (SW 22.5.78)
IPC: B66F7/14
Filed: 1977-09-23
Abstract: The elevating platform is guided between two vertical columns, one having an electric motor at the top. This is directly coupled to an elevating screw driving the platform elevating nut. Underneath this is a follower nut, a side projection moving parallel to a vertical rod mounted between compensating springs. Rollers guide the platform and, at top or bottom of the travel, the projection tilts a stop washer which grips the rod and actuates microswitches. The other column has a chain under tension. If this breaks, a spring assembly operates a cable to tilt the lower washer and stop any movement.

Title: Slip=on rotary elements stamping on multi-stage press - uses rectangular plate stamping with subsequent removal of corners
Inventor: WASILEWSKI PRZEMYSLAW DR ING
IPC: B21D22/26
Filed: 1977-12-02
Abstract: The process is used for stamping slip-on rotary elements from rectangular strips on multi-stage presses. In the first working step a rectangular plate is cut off from the strip, and simultaneously a shaped piece (1) is punched out. This piece has a greater diameter than the finished product, but is of smaller height. In this step of the plate four corners (3), 90 deg. apart, waste pieces are left over. In the next step the flange formed by the four corners is first cut off and the final product is shaped, using an inner resilient counterholder. The process reduces material losses and number of production steps.

Title: Baking flat pastry e.g. crackers - with air admixed to specified dough density before continuous strip baking in conveyor oven
Inventor: ATHENSTAEDT DIETER DIPL ING
IPC: A21D8/00
Filed: 1978-01-07
Abstract: Flat pastry, such as crackers, is produced continuously by introducing air in controlled quantities into the dough, prepd. from flour, water and other additives, until the dough emerging from the kneading machine has a density of 0.44-0.55g/cm3. The dough is stretched and squeezed before it is applied to the belt of a continuous baking oven. Evapn. and cooling is prevented before the long strip is cut into squares with a moisture content of 3-10%. This prevents the scrap produced by the individual mfr. of square crackers. The prod. is of uniform quality, and throughput and productivity are greatly improved.

IPC: H01H9/52
Filed: 1978-01-09
Abstract: To ensure the best possible dissipation of the heat produced at the current-conducting parts, particularly at the contact points of its moving operating pin (8), the switch has a head housing (21) which is constructed in one piece with the metallic carrier (16) of a contact member (14) constructed as tulip contact. The cross-section of thermal conductivity only changes from the outside of the head housing, emitting heat, to the connection between contact carrier and fixed contact member by 20% at the most, referred to the smallest cross-section. In addition, the contact carrier (3) establishing the electrical connection to the lower part of the operating pin is preferably integral with the lower housing part (1). The corresponding cross section of thermal conductivity meets the same condition. <IMAGE>

Title: Acoustic wind velocity measurement appts. - sends acoustic signal into atmosphere, and wind velocity is calculated from its frequency spectrum and Doppler frequency shift
Inventor: PETERS GERHARD DIPL PHYS
IPC: G01S15/58
Filed: 1978-04-10
Abstract: Acoustic signals (A) with fixed frequency and duration are sent into the atmosphere, and the scattered signal returning from the atmosphere is received. The frequency spectrum and th wind velocity are calculated from its comparison with the sent out signal and the Doppler frequency shift. The received signal is split by filtering in a series of evaluation functions allocated to individual frequency ranges. A maximum amplitude function is selected from the evaluation functions of a propagation time interval. A frequency allocated to it is used for the Doppler difference formation.

Title: Knitting machine stitch-cam adjustment mechanism - providing individual or simultaneous action on all cams
Inventor: SCHINDELE ALFRED
IPC: D04B15/34
Filed: 1978-12-29
Abstract: A mechanism for adjusting the stitch cams of a circular knitting machine by which the cams can be adjusted individually or all together comprises a cranked lever, one end of which controls the height of the stitch cam, the other end being connected to a spiral groove in a setting dial, by rotation of which the corresponding stitch cam can be adjusted independently of the others. The setting dials are all mounted in a rotatable ring surrounding the needle cylinder, displacement of which effects simultaneous adjustments of all the stitch cams. The mechanism is simpler and cheaper than existing ones, and the principle can be applied equally to dial-needle stitch cams as well as to cylinder-needle cams.
