Title: Process for producing moulded parts from plastic
Inventor: KUISS KURT
IPC: B29C43/52
Filed: 1988-12-23
Abstract: The invention relates to a process for producing thick moulded parts or moulded parts with regions of varyingly thick cross-section from thermoplastic material, in which a preform or parts of such a preform produced in a prior operation is or are placed in a compression mould in order to compress the preform into the finished moulded part under pressure and heat. To make such a process more cost-effective, before it is placed into the compression mould, the preform is gradually cooled or allowed to cool externally from the production temperature to as low a temperature as possible, at which the preform can however still be deformed under the pressing pressure of the compression mould, then the compressing into the final shape of the finished moulded part is performed and the moulded part is finally cooled or allowed to cool to ambient temperature.

Abstract: An elastic mounting comprises an elastic rubber spring member (3) located between two connecting members (1,2) in order to support a vibrating load, whose vibration spectrum includes both low frequency and high frequency vibrations, in particular motor vehicle engine mountings. In parallel with the spring member (3) is fitted with an electrostrictive or magnetostrictive actuator (4) in such a way that one face thereof (4.1) is rigidly coupled to a connecting member (1 and 2) of the spring member (3) and its other face (4.1) is rigidly attached to a seismic mass (9). A sensor which detects the alternating forces, alternating accelerations or vibrational displacements due to the vibrating load (L) is provided and is connected to the actuator (4) via an amplitude and phase regular and amplifier, wherein the regulation is so designed that the actuator (4) minimises the alternating forces, alternating accelerations and vibrational displacements applied to the sensor.

Filed: 1989-03-08
Abstract: With the device (2), two parts (5 and 8, 10) of different expansion behaviour which can be joined to each other are to be bonded. For releasing this bond, in particular a heating apparatus (12) is provided. At an assembly temperature (Tm), above an operating temperature (Tb), a small assembly gap (19) is formed between the parts to be bonded. According to the invention, an insert (8) is to be introduced in a recess (7) of an outer bonding part (5) of relatively great coefficient of expansion ( alpha 1). This insert can be cooled to the operating temperature (Tb) and contains an inner part (10) of a material of a comparatively much lower coefficient of expansion ( alpha 2) and also an intermediate element (9) of good thermal conductivity, bounding the assembly on one side. This intermediate element is deformed during the cooling phase from the assembly temperature (Tm) to the operating temperature (Tb) and thus forms a thermal contact with respect to the outer bonding part (5). This bonding part is provided with the heating apparatus (12). <IMAGE>

Title: Regeneration of carbon filters for Diesel IC engine - using reference airflow to monitor pressure build=up on filters to determine regeneration point
Inventor: BRESSLER HARALD DIPL ING
IPC: F02B3/06
Filed: 1990-03-14
Abstract: The Diesel exhaust passes alternately through two filters (7.1,7.2) via control valves (4.1,4.2). The non-operating filter is tested by applying a fixed airflow (15) and measuring the pressure build-up via pressure sensors (6.1,6.2). When the pressure build-up reaches a set level the filter is regenerated by passing through it a heated airstream. If the filter does not require regeneration then the valves switch the exhaust back through it. A processor control monitors the operating filter at set time intervals. These intervals are shortened as the pressure rises i.e. as the filter starts to clog. No interruption in the engine is required. ADVANTAGE - Fully automatic regeneration of the filters, optimum regeneration times.
