Patent DE-3929242-A1 (DE)
Title: Interference-free processor pref. for ultrasonic echo ranging - compares frequency of received echoes with reference frequency for discrimination against short sequences of impulsive noise
Inventor: RUMP HANNS
IPC: G01S7/527
Filed: 1989-09-02
Abstract: Echoes aroused by transmission of an ultrasonic pulse sequence  are picked up by a microphone (1) and amplified (2) for frequency comparison (3) with a reference signal from an oscillator (4). Signals whose frequency exceeds that of the oscillator are forwarded (7) to processing logic (6). A portion of the amplified signal (10) is digitised (5) and applied (8) to the processor (6) which is caused to respond only to a stip-ulated min. number of successive impulses, not normally attained by any noise sequence. ADVANTAGE - Noise immunity is improved considerably by neglect of pulse sequences of less than min. length.

Title: Weighing vehicles while in motion - forming quotient from wt. signals derived independently from front and rear weighing cells
Inventor: HAEFNER HANS WILHELM
IPC: G01G19/03
Filed: 1989-09-06
Abstract: Front and rear weighing cells are spaced in the direction of travel of the vehicle about the middle position of a vehicle wheel to cover a certain measuring range. The resultant signals are detected and evaluated to ascertain the wt. The weighing signals (G1,G2) of the cells (2a,2b) are independently detected but set in relation by forming a quotient. When the latter approaches a first variable threshold value (V1), evaluation of the weighing signals follows for ascertaining the wt. until a second variable threshold value is attained. The threshold values are symmetrically arranged in relation to the measuring range. The first threshold carries the quotient of the weighing signals between 2 and 7, pref. 5. ADVANTAGE - Simpler and more accurate.
Patent DE-3934007-A1 (DE)
Inventor: CHLEBDA STANLEY
IPC: H04B3/54
Filed: 1989-10-11
Abstract: A DC powered transmitter, eg for fluid flow rate, temperature or pressure, gives a dc signal, in accordance with the sensed variable, supplied over a two-wire line W1, W2 to a receiver 13 in which a DC voltage supply is connected to the line through load resistor 12. Across resistor 12 is an output signal in a predetermined current range for operating an indicator. The same line supplies operating power to the power input terminals of the transmitter through a switching-type step down power regulator 17 that gives constant power under high voltage-low current as well as under low voltage-high current conditions, thereby making more power available to the transmitter and increasing its load drive capability. <IMAGE>
Patent DE-3937337-A1 (DE)
Inventor: HOELSCHER ANDREAS
IPC: A47B57/52
Filed: 1989-11-09
Abstract: The invention relates to a shelf with cantilever brackets for heavy loads, in particular long products made of wood, plastic or metal, with supports and cantilevers brackets (5) extending from these. In known shelf systems, hanging and removing the cantilever brackets, which can generally only be effected at a certain angle, is problematic. For replacing or adding a cantilever bracket, in the event that a long length and/or small distance between shelves is involved, the brackets above it, with the loads on them, must previously be removed, involving a corresponding amount of work and time. These problems are solved using the invention, in that the cantilever brackets (5) can be fixed in the supports by lowering after horizontal insertion, two hooks or claws (10) being provided for each cantilever bracket, which respectively comprise a catch (11) and a claw end (12), the claw ends (12) at least partially gripping the flange from behind after lowering. The claw ends (12) are expediently designed with trapezoidal cross-section and angled away from the catch (11) and the angles of the claw ends (12) of two hooks (10) attached to a cantilever bracket (5) are directed mirror symmetrically inwards. The design of the cantilever bracket shelf according to the invention makes it particularly easy to assemble and vary. <IMAGE>

Title: Ascertaining particle content in gases and liquids - registering light dispersion in bridging zone between Rayleigh and Mie dispersion
Inventor: TRINKAUS HELMUT DR
IPC: F02B3/06
Filed: 1990-08-10
Abstract: Four components, arranged rectangularly symmetrical with a common optical middle point, of an optical sensor system can be activated as a source and/or receiver. Dispersed and transmitted light measurement is made when one component is activated as a source and two as a receiver. A geometrical equal value measuring combination is achieved by changing the transmitting activity of the remaining fourth component. For two geometrical equal value measuring combinations, all four partial sections defined by the sensor system and crossing the optical paths twice in the same direction are used. Changes in prim. intensity, detector sensitivity and window cloudiness are eliminated by computation. Characteristic values for the dispersing medium are registered. USE/ADVANTAGE - Soot content in diesel exhaust gases while on the move. Exact reference values used to eliminate errors.

Title: Device for making hollow shapes from material which softens when hot - mould holders moving through cooling station each have drive unit which engages common drive shaft and turns mould about two or more axes
Inventor: BINDLER UWE DIPL ING
IPC: A23G1/21
Filed: 1990-11-07
Abstract: In a device for forming hollow shapes from a material which becomes liq. when heated, moulds move on a conveyor (T) from an entry station through a cooling station, in which they are rotated about a number of axes, to an exit station. Under this invention, the moulds are placed in sliding holders which each have a drive unit for producing the rotation movements. Each drive unit is connected by its input member to the output shaft of a rotating drive system which serves all of the holders. This shaft extends from the entry station to the exit station, and engages the input member of each holder drive unit at the entry station, and disengages from it at the exit station. This shaft may be in the form of a friction shaft by which the input members of the drive units, in the form of friction wheels, are rotated. Alternatively, the drive system shaft may be a toothed shaft by which the drive units, in the form of gear wheels, are driven. USE/ADVANTAGE - Used in moulding hollow shapes from materials which become liquid when heated, and especially from chocolate. The rotation of the moulds about a number of axes is made possible with the least possible mechanical effort of the conveyor, and a high rate of throughput is achieved.
