Title: Electronic circuit for quartz wrist watch - allows second hand to be set by electromagnet which can be switched out by minute signal
Inventor: MEIER THOMAS
IPC: G04R20/08
Filed: 1990-02-02
Abstract: The circuit serves for fire adjustment of the second hand of an economically mfd. wrist watch  with max. deviation of plus or minus 45 seconds per year.  If necessary it is possible to snyc. the watch wirelessly with an externally prepared DCF77 signal. The second hand is put into fast forward mode  until it reaches the 60 second mark by a freq. higher than the normal one step per second, tapped from the oscillator's freq. divider.  Also continuing at a high rate from the same source after finishing adjustment  using a minute pulse derived from the DCF77 signal.  The second hand is set and the 60 second memory of the watch circuit is reset using the same switch. USE/ADVANTAGE - RE-adjustment of precision watch without mechanical resetter.  Independent of reaction time of adjusting person.

Patent DE-4030854-A1 (DE)
IPC: G01V8/12
Filed: 1990-09-29
Abstract: To detect the edge (W) of a layer (N1) of the workpiece to be stitched, before the stitch-forming site of a sewing machine (1), the detection point is illuminated and the intensity of the fraction of the light reflected at the detection point and the intensity of the fraction of the light transmitted at the detection point  are measured separately from each other. In each case, the measurement for which the measured value of the intensity would be expected to make the more distinct jump if the edge (W) of the workpiece to be stitched appears at the detection point is selected in order to generate a signal for detecting the edge (W) of the workpiece to be stitched. Preferably, the measurement selected is that the measured value of which has the higher amplitude before the edge (W) of the workpiece to be stitched has appeared.

Title: Respirator control using sensor to measure breath vol. or flow - and supplying signal processor also receiving resistance, inverse compliance and any leakage vol. values as well as threshold values to control breathing pressure
Inventor: SCHALLER PETER DR SC TECHN
IPC: A61H31/02
Filed: 1990-12-03
Abstract: A volume flow sensor (11) measures the flow to the patient.

If the voltage, UV', becomes negative during exspiration, it is extended to a further input of the integrator via a diode (3). The signal, UV grenz. is set in advance by another potentiometer (15). The signal UV' is also applied to the input of a multiplier (6) and the input of a double path rectifier (4) where it reaches the other input of the multiplier via a resistance network (5). ADVANTAGE - Keeps patient breathing over long period despite low natural breathing flower while avoiding disadvantages of controlled breathing machine.

Abstract: The prepn. of 2,2,5,5-tetramethyl cyclopentane carboxylic acid (I) comprises gas phase rearrangement of 2-isocyano-1,1,3,3-tetramethyl cyclopentane (II) to 2-cyano-1,1,3,3-tetramethylcyclopentane (III) which is then hydrolysed to (I). The rearrangement is at 550-650 (esp. 570-620) deg.C and 10 power (-4) to 30 mbar. USE/ADVANTAGE - (I) can be used in the prepn. of a N-L-aspartyl-N'- (alkylcarbonyl)-1,1-diamino ethane deriv. of formula (IV) which is a water soluble sweetener which has no bitter after taste and is 1000 times sweeter than sucrose. In (IV), R = 2,2,5,5-tetramethylcyclopentane carbonyl (II) can be easily prepd. from 2,2,5,5-tetramethylcyclopentanone. The gas phase rearrangement of (II) to (III) avoids the occurrence of disruptive side reactions. In contrast to known prepns. of (I), no transition metal reagent is necessary, and no protective gas need be used. There are no sepn. problems resulting from the formation of unwanted prods.

IPC: E04C2/52
Filed: 1991-04-29
Abstract: The wall- or ceiling cladding is in plate sections, with passages at the side furthest from the room, connected to feed and return pipes, and through which a heating or cooling medium flows. Between the feed and return pipes (5) and the passages or pipes of the plate section (1) a pipe joint (7, 8) is formed, and which is relieved of the plate-section weight by a link (10) between the section and the supporting structure. The hinge axis of the pipe joint can be coaxial to that of the link. The joint can be formed by a pipe end turning in a socket. The pipe end can be enclosed by a bush so as to leave a radial clearance. The bush engages in a bearing bore in the supporting structure, and is fixed to the plate section. ADVANTAGE - The individual plate-sections are removable for a distance sufficient to allow maintenance work behind them, without having to shut the heating or cooling system down.

Title: Resonator control for two-mode high pressure pulsed gas laser e.g. of TE carbon di:oxide type - converts optical output signal into electrical pulses, and evaluates them to adjust resonator length and to stabilise pulses via piezo-regulator
Inventor: ALBRECHT HANNES DR
IPC: H01S3/139
Filed: 1991-07-17
Abstract: The resonator control uses a reception module to convert the optical signal comprising one or two frequencies provided by the laser into a proportional electrical signal. The latter is fed to an integrator (6) which extracts and integrates the HF component resulting from the hovering between 2 frequencies. A time difference value, defining the difference between a laser pulse and a stimulation pulse, is fed with the integral value to a processor (11). The processor compares the two values with corresp. stored values for preceding laser pulses, to obtain control pulses fed to the pize-regulator (1), via a D/A converter (10). The piezo-regulator varies the laser resonating cavity to maximise the integral value. ADVANTAGE - Rapid tuning of laser wavelength.
