Title: Method for phase-locked frequency conversion
Inventor: SCHMITZ GUENTER DR ING
IPC: H03L7/183
Filed: 1988-03-30
Abstract: Methods for phase-locked frequency multiplication or, respectively, frequency division in which, from an input frequency, an output frequency is generated which is in a fixed rational relationship to the input frequency, are often used in measuring technology, particularly in the measuring technology of internal combustion engines. The invention is based on the object of improving methods of this type in such a manner that the required conversion of the input frequency follows faster and, in particular, no settling times or only very short settling times are required. In a method of the said type, this is achieved by the output phase (T2) being synchronised mathematically with the input phase (T1) by means of a controller. In this arrangement, the phase angle of the output signal can be synchronised by the input signal. It is possible, in particular, for the phase angle of the output signal to be set with the aid of a phase shifter or settable divider at the frequency output (Figure 1).   <IMAGE>

Title: Method and device for utilising coldness in a manner which is independent of time and for utilising the heated-up condition of a cold medium
Inventor: REICHSTEIN VOLKMAR DIPL ING
IPC: F17C9/04
Filed: 1988-05-27
Abstract: The invention relates to a method and a device for utilising, independently of time, the coldness of a medium available in a cold condition and utilisation of the medium itself in a heated-up condition. It is frequently the case that a cold medium is used in the same operation to supply coldness and is otherwise used as a processing medium in a heated-up condition, without the requirement for coldness and the requirement for processing medium occurring at the same time. This results in the problem that the coldness of a cold medium often remains unused. This problem is solved according to the invention in that at least some of the cold medium brought into use is used to cool a cold storage unit, from which coldness can then be independently taken. <IMAGE>

Title: Method for a program-controlled telephone switching system with a central controller which performs all switching functions
Inventor: LONCKE BERNARD
IPC: H04Q3/62
Filed: 1988-07-08
Abstract: The invention relates to a method for a program-controlled telephone switching system with a central controller which performs all switching functions and which has access to storage arrangements in which all the information required to perform the switching functions is stored. In a central memory SP, separate memory areas (e.g. TS, QS) are provided for each traffic type (e.g. internal traffic, exchange traffic) in which the tones or times required for a call set-up are in each case stored in a suitable manner. When a request for tones or times is received from the system, it is automatically assigned to the corresponding memory area (e.g. TS, QS) on the basis of its origin and is used there to activate the required tone or time. Centrally different tones and times which are dependent on the traffic type can thus be activated in simple fashion. <IMAGE>

Patent DE-3839546-A1 (DE)
Title: Slate-dressing machine
Inventor: HOPPEN EWALD A
IPC: B28D1/32
Filed: 1988-11-24
Abstract: With the slate-dressing machine, cover slates of any desired pattern contour are cut out of raw slate tablets in a punch-like cutting operation without the slate breaking in the process. This is because the raw slate tablet (7) is clamped on both sides with clamping elements (8, 11, 13) in such a way that only a narrow band area (11, 13) with pattern contour leaves space for the passage of the form cutter (1) configured in a channel shape or tubular shape with the cross-section of the pattern. Unrolled in a plane, the form cutter (1) forms one or more isosceles triangles or, in another embodiment, one or more right-angled triangles, the sides or the catheti of which represent the cutter blades of the form cutter. These measures enable large cutting angles to be used and enable the cutting pressure to be decisively reduced and made uniform, all without cutter tips which are too acute. With the combination of the measures according to the invention, high working speeds and at least ten times the number of pieces per unit of time as hitherto can be achieved. <IMAGE>
