Patent DE-3141542-A1 (DE)
Title: Method for frequency calibration of piezoelectric resonators
Inventor: MUELLER SIEGFRIED DR RER NAT
IPC: H03H3/04
Filed: 1981-10-20
Abstract: Piezoelectric resonators can be tuned to a particular resonant frequency due to the fact that metal is applied to the electrode areas until the required resonant frequency is reached. This has hitherto been done by vapour-depositing metal in a vacuum whilst at the same time measuring the frequency. The metal deposition can be carried out in a much simpler manner by galvanic deposition with little expenditure on material and time and with lower losses of the metal to be applied. If the deposition occurs with a constant current intensity, the duration of deposition is directly proportional to the decrease in resonant frequency. In this manner, for example thickness-mode transducers of piezoceramic material can be calibrated in that gold is deposited on the electrode area on one side of the transducer.
Patent DE-3141974-A1 (DE)
Title: Turret head with horizontal axis and retractable tool carriers for lathes or the like
Inventor: BOFFELLI PIER CARLO
IPC: B23B29/24
Filed: 1981-10-22
Abstract: The invention relates to a turret head with horizontal axis and a plurality of tool carriers, of which some are parallel to the axis of rotation of the turret head are displaceable and in the turret head so as to be able to occupy an outer working position and a withdrawn rest position in the turret head when the machining is complete. The tool carriers are generally suitable for internal machining and in the working position in the turret-head housing are locked as close to the contact point of the tool cutting edge as possible in order to reduce the projecting length which is exposed to the cutting forces. This is achieved in that each tool carrier has its own hydraulic circuit which is independent of and separate from the others, only operates when the tool carrier has reached its working position and actuates the locking means, which consist of radial pistons, so that a lateral pressure force is produced which securely clamps the tool carrier in its bearing sleeve.

Title: Elastic mount, in particular for the engine in motor vehicles
Inventor: HEITZIG JUERGEN DIPL ING
IPC: F16F13/10
Filed: 1981-10-28
Abstract: An elastic engine mount with hydraulic damping, the effect of which is controlled by a flexible diaphragm in conjunction with rigid stop elements. According to the invention, the ability of the diaphragm to move is influenced in such a way that it responds only to relatively large vibration amplitudes and cancels the restriction of the compensating flow, yet is indifferent to relatively small amplitudes and, with the retention of its free travel, consequently maintains the restricting effect.
Patent DE-3143545-A1 (DE)
Title: Method and device for controlling the speed of revolution of guide roller drives on through-running webs
Inventor: VORWERK JOACHIM ING GRAD
IPC: B65H23/188
Filed: 1981-11-03
Abstract: In multimotor drives for through-running webs, guide rollers have the function of guiding the web in the free area between the clamping points whilst maintaining specific properties such as length, extension or tensile stress. So that no significant forces are exerted on the webs by the guide rollers, the speeds of rotation of the guide rollers are controlled. In this process, the static amplification of the control, in the region of small control deviations in the speed of rotation, is set at a high value and, in the case of relatively large control deviations in the speed of rotation, at a higher value. The transition point from large to small amplification can be optionally predetermined. <IMAGE>

Title: Connecting piece for lighting fixtures having rail-shaped parts
Inventor: BAETZ RUDI
IPC: F21V21/005
Filed: 1982-04-20
Abstract: The invention relates to a connecting piece for lighting fixtures having rail-shaped parts and, e.g., a fluorescent lamp, which are juxtaposed to form long rows of luminaires. The connecting pieces used to date for this purpose are fittingly inserted into the rail-shaped parts of the lighting fixtures to be connected and connected thereto by numerous clamping screws. However, the preassembly of the numerous clamping screws and tightening them at the installation site is complicated. The invention substantially facilitates the work of assembly by providing as connecting piece for in each case two lighting fixtures a profiled rail piece (14) on which two gripping levers (19) having eccentrically shaped projections (20) are pivotably mounted. When these gripping levers (19) are pivoted beyond their dead-point position into their active position, the projections bear in a clamping fashion against the rail-shaped parts (12) of the lighting fixtures given elastic deformation of these rail-shaped parts and/or the profiled rail piece. The invention is principally used in the production of long rows of luminaires made from lighting fixtures having fluorescent lamps. <IMAGE>

Title: Method and device for generating circuital vector fields
Inventor: CROSTACK HORST-ARTUR PROF DR I
IPC: G01D18/00
Filed: 1982-05-10
Abstract: The invention relates to a method and a device for generating circuital vector fields, in particular in nondestructive materials testing, using eddy-current engineering, in which a circuital vector field, the formation of whose current is measured and evaluated, is induced in the test specimen via means of a coil excited by an electric pulse. The main field of application of the invention is nondestructive materials testing, but the invention can also be applied in other fields in which the generation of a circuital vector field is required. The invention consists in that the coil which serves to generate the magnetic field inducing the circuital vector field is excited by a prescribable monofrequency oscillation (test frequency oscillation) or by a plurality of such prescribable monofrequency oscillations, as well as by an enveloping function that is superimposed in a multiplicative fashion on said frequency or frequencies and has a prescribable length and shape. According to a further inventive concept, an eddy current pulse generated in this way can be fed as a test pulse to the coil with a faultless workpiece located therein and after passing through the workpiece be received, analyzed and compared to a desired value, after which the pulse parameters are corrected with the aid of the difference established. <IMAGE>
