Patent DE-4319066-A1 (DE)
Title: Circuit arrangement for a controllable oscillator
Inventor: POWELL WILLIAM EDWARD
IPC: H04L7/033
Filed: 1993-06-09
Abstract: Oscillators having high quality and reliability for a long time are required in order to ensure interference-free transmission of digital information. Voltage-controlled oscillators are used for this purpose, which are tuned via a microprocessor and a digital to analog converter and are a component of a phase locked loop. In the case of these arrangements, a compromise must be found between the control range and stability, the control characteristic is non-linear, and the resolution is limited by the step width of the digital to analog converter. An oscillator whose frequency can be varied linearly over a large control range without the stability of the oscillator being influenced is specified by the circuit arrangement according to the invention. The circuit is supplied with a conventional 5 V operating voltage. To this end, the frequency of a fixed-frequency generator (1) is divided down to the desired frequency by means of a frequency divider (2) whose division ratio can be varied in very small steps, and jitter produced in this case is filtered out using a simple phase locked loop (3). The oscillator can be used universally as a clock generator in any digital circuit arrangement. <IMAGE>
Patent DE-4321439-A1 (DE)
Title: Domestic fire and oven firing system - uses reaction chamber lined with catalytic material producing carbon-dioxide and water and preventing secondary reaction with nitrogen in air
Inventor: HUNCK HEINRICH
IPC: B01J19/12
Filed: 1993-06-28
Abstract: The reaction chamber for hydrocarbons with oxygen is lined with catalytic material. This maintains the reaction-energy process of combustion in an elevated exothermal state of equilibrium reaction such that the product of reaction between hydrocarbons and oxygen in the chamber is mainly carbon-dioxide and water. Secondary reaction with the nitrogen in the air is prevented. The oxygen in the air can be so delivered to the material as to give best possible chemical reaction. ADVANTAGE - Allows variation of oxygen supply.

Title: Drying installation
Inventor: SCHWARZ JOACHIM DIPL ING
IPC: F26B11/18
Filed: 1993-09-10
Abstract: An installation for drying workpieces wetted with liquid has a drying chamber (11) with inlet openings (13) and outlet openings (14). Within the drying chamber (11) a workpiece carrier (21, 22, 23, 25, 26, 27, 31, 34, 35, 36) is mounted such that it can swivel and be driven via a drive shaft (41) which axially penetrates the end side of the drying chamber (11). This makes it possible to impart a non-stationary swivelling and rotating movement to the workpiece carrier. The drying air is extracted from the drying chamber (11) by means of a flow machine (51), a negative pressure within the drying chamber (11) of 0.90 to 0.97 bar absolute being set. The drying air is heated by a radiator (55) and within the drying chamber (11) set to a temperature of 20 to 70 DEG C. The non-stationary swivelling and rotating movement, on the one hand, and the extraction of heated drying air, on the other hand, make an extremely efficient drying process possible. The required outlay on energy, based on the drying power, is extremely low compared to conventional dryers because of the low, required electrical connected loads possible herewith. <IMAGE>

Title: Computerised rotary actuator for synchronised displacement of glass bottles
Inventor: DUTTO FANTINI IVO
IPC: G05B19/042
Filed: 1994-04-21
Abstract: The glass vessels are displaced synchronously by a series of stations made up of a mechanical installation actuated by asynchronous motors. Each of the motors ensures execution of a cyclic process.The cyclic process (Fi) is controlled from a detector that emits an impulse on each cycle. The impulse is sent to a central computer which is programmed to process these impulses. The processing algorithm determines the difference between the number of bottles processed at any instant since the last synchronisation, and the difference between the numbers of bottles transported between two process stages (Fi,Fj). The difference is used to control the frequency of the alternating supply to the asynchronous drive motors.

Patent DE-4434653-A1 (DE)
Inventor: HEHL KARL
IPC: B29C45/76
Filed: 1994-09-28
Abstract: The invention concerns a method and device for influencing machine setting values. After characteristic properties of the products manufactured in the test phase have been determined by tests and a plurality of process curve shapes have simultaneously been determined, a relationship is established between process characteristic numbers characterizing the process curve shapes and the characteristic properties of the parts. Corresponding process characteristic numbers are also determined during production. As a result of this signal analysis, when a given desired characteristic property (QMsoll) is stipulated, the process characteristic numbers (PKZ) which are decisive for this characteristic property can be determined in order to ascertain the machine setting values (MG) which are decisive for the characteristic property. During production, the characteristic property to be expected (SQMber) can then be calculated such that, on the basis of a nominal value - actual value comparison, a differential value QM can be determined which can be set at a minimum by influencing the decisive machine setting value (MG) which is likewise calculated. The quality of the injection-moulded parts can thus be improved.
