Title: Rotating probe device for determining form variation and positional variation on test specimens
Inventor: SOMMER HANS-JOACHIM
IPC: G01B5/20
Filed: 1981-01-12
Abstract: The invention relates to a rotating probe device for determining form variations and positional variations on test specimens, in particular for roundness measurements, with the aim of increasing the accuracy of the measurements and decreasing the outlay on correcting the measurement results. In this case, influencing of the measurement result by gravity is avoided even in the case of horizontal mounting of the axis of rotation of the probe device. In the invention, the probe is mounted in a probe receptacle, which is arranged on a horizontally mounted spindle, in a manner radially displaceable with respect to the spindle axis. The measured-value transmitter, which is operationally connected to the probe, is arranged in alignment with the probe longitudinal axis, in such a way that the probing direction, probe and measured-value transmitter lie in an axis extending radially with respect to the test specimen. The probe is mounted in the probe receptacle in low-friction or frictionless guide elements. <IMAGE>

Title: Method and arrangement for measuring absolute rotations
Inventor: ULRICH REINHARD DR PROF
IPC: G01C19/72
Filed: 1981-06-10
Abstract: The method, known per se, of a Sagnac ring interferometer for measuring rotation is modified in that a phase shifter is arranged at each end of the annular light path. These phase shifters are operated in push-pull mode. They thus simulate an imaginary rotation of the ring at a rate which is connected essentially linearly to the speed of change of the optical phases of the light rotating in the light path. This imaginary rotation is utilised in order to compensate the actual rotation to be measured. For an accurate evaluation of the actual rate of rotation, phase shifts which alternately rise linearly and drop linearly over time of in each case one such variable are produced by means of the phase shifters in such a way that essentially compensation always occurs. The difference in the time of the rising phase states and the falling phase states is strictly proportional to the actual rate of rotation.

Title: Heating and sprinkler system
Inventor: HOFMEISTER ARNO ING
IPC: A62C35/00
Filed: 1981-07-29
Abstract: In a heating and sprinkler system (10) consisting of a heating system (66) with a solar collector system (19) and a space-cooling system (21) which delivers waste heat, it is proposed for the purpose of saving a dedicated low-temperature store to use the sprinkler reservoir (12) as a low-temperature store which stores excess solar collector heat not required by the heating system (66) as well as excess waste heat for output during the colder season. In case of need, heat can be fed by the heat pumps (130 and 132) from the sprinkler reservoir (12) into the buffer reservoir (64) and thus into the heating system (66). <IMAGE>

Title: Heating installation using a heat pump for room heating with hot water
Inventor: STAMM GERHARD ING GRAD
IPC: F24D3/18
Filed: 1981-09-16
Abstract: The invention relates to a heat pump for room heating with hot water, without additional external heat. The mode of working of the heat pump is adequately known, see inter alia "Lueger Encyclopaedia of Technology, Volume 7 - Lexicon of energy technology and engines", in which the "left"-running Carnot cycle is described in detail, according to which the heating medium - hot water - is raised from a lower temperature to a higher one by a compression and expansion process with the aid of supplied energy. Normally, in this process, the heat contained in an available heat carrier, such as ambient air, ground heat or groundwater, is extracted and the heating medium - hot water - is brought to a higher temperature level. The performance number in these installations is between 2 and 3. Only with great technical power expenditure would it be possible to bridge a high temperature difference between an available heat carrier and the desired delivery temperature without reducing the performance number. The invention of the application is intended to avoid the abovementioned disadvantages and at the same time considerably reduce the technical outlay and the installation costs. Mode of operation: when the room temperature falls below a set value, the starting heating (5) is switched on via a room thermostat, the operating medium, e.g. Freon 12, is heated, drawn in by the compressor (1) which is now switched on and pressed into the liquefier (4). In this case, the operating medium which is now energetically charged delivers energy in the form of heat to the hot-water heating system during expansion (outlet from the expansion valve). At the same time, via a pipe coil in the liquefier, which is connected to an identical one (6) in the evaporator, the operating medium is kept at a temperature around 10 DEG C. As the performance number depends on the temperature gap between heat source and heat consumer, it will not become smaller even in the case of low outside temperatures. The compression which is controlled by the forward-run temperature is achieved via the thyristor-controlled motor or compressor. The aim is thus achieved of operating the heat-pump installation economically with a compact installation without calling on a separate external heat for the evaporator. <IMAGE>

Title: Process for the preparation of cinnamic acid and coumarin
Inventor: KERN RUDOLF DR
IPC: C07C51/353
Filed: 1981-10-08
Abstract: The free acetic acid formed in cinnamic acid synthesis by the method of Perkin delays the reaction sequence by repression of the reaction-favouring enol form of the acetic anhydride. The same is true of the reaction of acetic anhydride with salicylaldehyde to give coumarin. The interfering free acetic acid is neutralised by addition of, preferably, potassium carbonate with the formation of potassium acetate, which in turn acts as a reaction-favouring condensating agent, resulting in shortening of the reaction time and repression of resin formation.

Title: Arrangement for pulse measurement using a photoelectric useful signal sensor
Inventor: WILDEN ROLF
IPC: A61B5/024
Filed: 1981-12-23
Abstract: The invention relates to pulse measurement with the aid of a photoelectric useful signal sensor. If the pulse measurement is taken when a patient is under stress, e.g. from running, rhythmic interference signals can arise which negatively influence the pulse measurement. In order to avoid this, an interference signal sensor is arranged in the vicinity of the useful signal sensor, and a circuit is provided which matches the amplitude of the two signals to one another in such a way that after subtraction the interference component arising in the useful signal sensor is eliminated, or at least reduced. <IMAGE>

Title: Method for measuring rotational speed and angle on a rotating system
Inventor: HELWICH PETER-JUERGEN ING GRAD
IPC: G01P3/481
Filed: 1982-02-26
Abstract: The invention relates to a method for measuring rotation and angle on a rotating system, in which a number of pulses and, in addition, a zero position signal are transmitted per revolution. The toothed discs present in any case for maintenance work on each machine can be used as pulse generators. The rotational speed signal determined by the measuring device is used to govern the rotational speed of the main machine. The instantaneous angular position, referred to the inherent "zero point" is fed per the data line to the rotational speed governor of the other main machine. In this way, each governor can calculate the position of the two shafts with respect to one another and can also calculate the deviation from the set desired position and, if desired, output correction signals to the actuators of the main machines. <IMAGE>

Title: Sound pick-up for acoustic guitars with steel strings
Inventor: SOMMERFELD RALF
IPC: G10H3/18
Filed: 1982-09-21
Abstract: To radiate relatively large rooms with sound by means of electrically amplified acoustic guitars without reducing the quality of the natural sound of the instrument, the sound pick-up was fabricated of two low-resistance induction coils wound in the same direction and having one magnetic field in each case of opposite polarisation. By connecting the two coils in parallel via a controllable decoupling resistor, the intensity of the output signal which corresponds to the frequency of the fundamental tones of the strings can be adjusted, resonance phenomena such as string feedback, too strong a sound of the fundamental vibration and differently loud sounds of the strings being compensated for so that a linear frequency response is produced. At the same time, this extremely reduces the sensitivity of the sound pick-up to mechanical vibration.

Title: Phase shift keying/amplitude shift keying (PSK/ASK) system with any number of stages
Inventor: WEIDENFELLER HERMANN DIPL ING
IPC: H04L27/36
Filed: 1982-11-24
Abstract: The invention provides a general-purpose phase shift keying/amplitude shift keying (PSK/ASK) system with any number of stages, selectable both inside (m = 2<n>) and outside (I = 2<n>-k) a geometric progression (n = number of bits/transmission stage, k = integer). For this purpose, n parallel binary baseband signals with n sine-wave carriers gn(t), in each case phase-shifted by the angle @1...@n of the carrier frequency fc representing an integral multiple of the bit clock (fbit) or the line clock (fs), are amplitude-modulated in n ring modulators at the transmitting end and combined with one another in a hybrid coupler with n inputs to form an m = 2<n>-stage PSK/ASK transmission signal or, in the case of transmission-end coding and receiving-end decoding of the k non-unique signal states, to form an I = (2<n>-k)-stage PSK/ASK transmission signal. The carrier frequency fc for the sine-wave carriers gn(t) and the bit clock fbit or line clock fs are coupled in phase-locked fashion by means of a phase-locked loop. At the receiving end, the carrier frequency fc is recovered from the spectral line of the bit or line clock derived from the envelope of the received signal with the aid of a simple phase-locked loop. The mean effective carrier power and the maximum carrier power are particularly low in the I-PSK/ASK systems (e.g. 7 PSK/ASK). In a practically implemented n = 8-PSK/ASK system, compared with the ideal values ... Original abstract incomplete. <IMAGE>
