Title: Phase-modulated interferometer II
Inventor: BAUER JUERGEN
IPC: G01J9/04
Filed: 1993-03-05
Abstract: The invention relates to a phase-modulated interferometer with a novel drive and signal conditioning. The object, of achieving overlay signals which are capable of evaluation in the case of a phase-modulated interferometer without complicated driving of the phase modulator, is achieved according to the invention in that the known phase modulator (2) is fed with a sinusoidal drive signal having a modulation frequency ( omega 0) and an amplitude ( phi 0), a multiplicative mixing is carried out of the overlay signal, generated in the interferometer, from the measurement and reference arm by a sine-wave signal which is rigidly coupled in terms of phase and frequency with reference to the drive signal and has a specific mixing frequency ( omega M), and, in an electronic bandpass filter (9), at whose filter frequency ( omega F) the sum frequency and difference frequency of two harmonics of the modulation frequency ( omega 0) and of the mixing frequency ( omega M) assume equal values, a cosine signal is filtered out in a conventional way for evaluating the phase shift, if the amplitude ( phi 0) of the drive signal fulfils the condition for a suitable operating point of the phase modulator (2). The invention is applied in phase-modulated interferometers, in particular for precision length measuring devices having a preferably heterodyne evaluation method. <IMAGE>

Title: Thermostatic frost protection for solar installations
Inventor: MEUCHT BERNHARD
IPC: F24D19/00
Filed: 1993-06-03
Abstract: For all-year operation of solar installations with water as heat medium, protection against freezing-up is absolutely necessary. In moderate regions, such as Germany, the solar circuit is materially separated from the domestic hot water circuit. By adding antifreezing compound, protection against freezing-up is then provided. The heat exchanger reduces the efficiency of the installation considerably. A new possibility is to empty the collector automatically when there is a risk of frost. To this end, a thermostatic valve, which already finds application in radiators and has a frost-protection position, is installed below the collector against the flow direction. The collector circuit is shut off from the domestic hot water by a non-return valve in the return and a solenoid valve in the flow. The solenoid valve is operated via the pump control. At the highest point of the installation, a ventilation valve must also be installed. When there is risk of frost, the thermostatic valve opens and empties the collector into the open. The latter can no longer freeze up. Since the heat exchanger can now be dispensed with, the costs for solar installations are halved. <IMAGE>

Patent DE-4330156-A1 (DE)
Title: Manifold
Inventor: REISERER WERNER
IPC: F24D3/10
Filed: 1993-09-07
Abstract: The invention relates to a manifold which comprises two housing halves, between which there is arranged a horizontal partition wall which subdivides the housing into a flow chamber and a return chamber, and the invention is used preferably in the case of heating-circuit distributors in hot-water-based heating systems. According to the invention, the two housing halves (1, 2) and the partition wall (3) are each formed from a U-profile. In this arrangement, the partition wall (3) is dimensioned such that it rests, with its outer surfaces (4, 5) of the mutually opposite legs of the U-profile, against the inner surfaces (6, 7, 8, 9) of the mutually opposite legs of the two housing halves (1, 2). This configuration of the manifold achieves, over the entire length thereof, a uniform weld joint on both sides and thus ensures uniform weld seams. The size of the flow and return chambers may, in a simple and sophisticated manner, be configured to be variable by virtue of a vertical adjustment of the partition wall (3) before connection to housing halves (1, 2). <IMAGE>

Title: Hand pliers for assembly purposes
Inventor: NEUMANN RAINER
IPC: B25B7/04
Filed: 1993-09-25
Abstract: The hand pliers are especially suitable for sliding sleeve type pipe-connecting systems for metallic and non-metallic pipes. They comprise essentially two pliers parts which are held together by a first hinge joint (1), each part of which is formed from a front limb for holding in each case one assembly jaw (17 and 18 respectively) and a rear handle limb (2 and 3 respectively) which is many times longer. In this arrangement, one of the two handle limbs (2 and 3 respectively) is divided into an inner, shorter handle part (19) and an outer, longer handle part (20). This outer handle part (20) forms, with a chain wheel (24) and a tension chain (27), a link mechanism for the purpose of achieving a greater assembly force. To turn the chain wheel (24) and thus tighten the hand pliers, use is made of a ratchet wheel (25) with ratchet teeth. Furthermore, a pawl (39) engages in the ratchet teeth (38) and prevents the handle limbs (2, 3) from springing back during the gripping operation. To release the pawl (39), a sliding plate (46) movable to and fro is provided. <IMAGE>
