Patent DE-3613801-A1 (DE)
Title: Arrangement for cooling surfaces
Inventor: BUHL RAINER DR
IPC: F28F13/02
Filed: 1986-04-24
Abstract: In cooling thermally very highly stressed surfaces, for example the bottom side of the crucible bottom in an electron beam evaporator, the problem arises that at the hot surface to be cooled the coolant forms vapour bubbles, which severely hinder the cooling. In order to improve the heat removal in a known way by means of a turbulent coolant flow, previously eddy-forming sheet metal deflectors were frequently inserted in the cooling channel, whereby, however, the rate of flow was sharply reduced and consequently vapour bubble formation was promoted. According to the invention, the coolant is introduced at high speed through nozzles tangentially into the coolant space, which exhibits an essentially cylindrical jacket surface, whereby the coolant is set in rotation and removed again via a line arranged in the vicinity of the axis of rotation. The bubble formation is thereby largely suppressed. Application of the invention: especially for surfaces highly heated by corpuscular beam bombardment. <IMAGE>

Patent DE-3725153-A1 (DE)
Inventor: PINTSOV LEON A
IPC: G01G19/393
Filed: 1987-07-29
Abstract: The inserting machine optimises the final weight of a mailpiece in order to obtain the maximum value from a postal weight category. Each of the enclosure types which may be inserted within the mailpiece is assigned a level of priority eg specifying that it should only be included in mailpieces whose final weight would lie within postal weight categories of less than a specified maximum weight. In addition, each of the enclosure types is assigned a nominal maximum per enclosure weight. A processing unit calculates the nominal weight of the essential enclosures of the mailpiece and the processing unit then selects other enclosure types for insertion within the mailpiece based upon the priority level of the enclosure type and the maximum weight of the enclosure such that the final weight of the mailpiece is substantially equal to a maximum allowable weight threshold for a given postage category. The level of priority of an enclosure can be entered into the system by a variety of means and can further be changed online from one collation processed to the next. <IMAGE>

Title: Electronic selenium optical memory
IPC: B60Q1/00
Filed: 1987-11-16
Abstract: A device (electronic selenium optical memory) is proposed which electronically (10) switches on the necessary lighting of the vehicle for exposure control of the vehicle steering wheel when an extraneous light intensity and amount of light strikes (11) the selenium cell as an oncoming light or rearward-direction light (20). The electronic system can be adjusted to pure warning signals which are detectable by yellow/red light intervals on the electronic system, it is also possible to warn the driver by acoustic means. The lighting is automatically switched off in a timed fashion or when the vehicle light is no longer required, e.g. when travelling through a tunnel. When travelling in twilight, darkness, in a tunnel or under street lights this invention is of great significance. When the ignition key is withdrawn, the lights of the vehicle go out automatically so as not to discharge the battery. <IMAGE>

Title: Output mirror for three-colour lasers, having adjustable reflection
Inventor: SCHMIDT EBERHARD DIPL PHYS DR
IPC: H01S3/08
Filed: 1987-11-25
Abstract: An output mirror for three-colour lasers, layer stacks for the blue and red component of the spectrum, optical wedge effect of at least one layer for adjusting the transmissibility in the green band. Output mirror for three-colour lasers having adjustable reflection. The invention can be used especially in ion-gas lasers which simultaneously emit three different wavelengths in the visible spectrum. In order to achieve this object, a mirror is used which consists of two layer stacks arranged one above the other, each of which consists of dielectric layers which alternately have high and low refractive indeces and have the same optical thickness. The optical thickness of an individual layer in a stack is a quarter of one wavelength in the blue part of the spectrum, and in the other stack it is a quarter of one wavelength in the red part. One of the central layers of one or both stacks has an optical layer thickness change (wedge effect). In consequence, it is possible to adjust the transmissibility in the central part of the spectrum.

Filed: 1987-12-16
Abstract: In an eccentric disc grinder, the grinding disc unit (7), during the machining of the workpiece, preforms a movement revolving around the eccentric shaft (4) driving the grinding disc (8). In order to prevent the rotary speed of the grinding disc unit (7) from being able to increase up to the rotary speed of the eccentric shaft (4) during idling as a result of the friction occurring at the bearing (6) carrying the grinding disc unit (7), a magnetic or electro-magnetic coupling device with a coupling part (20) fixed to the housing and a coupling part (21) fixed to the grinding disc is arranged between the grinding disc unit (7) and the housing (3). The two coupling parts (20, 21) face one another in the axial direction. One of the coupling parts is a magnet part with a magnetic field extending to the other coupling part. This interacts with the other coupling part in such a way that a holding force is exerted on the coupling part (21) fixed to the grinding disc and is thus exerted on the grinding disc unit (7), which holding force is effective in the peripheral direction of the grinding disc unit (7). <IMAGE>

Title: Process for the sinter-roasting of sulphide ores
Inventor: ROESER GERHARD
IPC: C22B1/06
Filed: 1988-04-27
Abstract: In the process for the sinter-roasting of sulphide ores, in particular of iron, zinc and lead ores, with addition of limestone as slag former and with air-blowing, the limestone is wholly or partially replaced by flue gas desulphurisation products containing calcium sulphite with a low fly ash content and a low chloride content. It has proved to be particularly advantageous to use flue gas desulphurisation products from those processes which show a low conversion efficiency of the calcium carriers introduced. It is particularly advantageous to mix the flue gas desulphurisation product with the sludge from the cooling tower make-up water treatment for producing a readily conveyable product of high calcium carbonate content, which can replace the limestone in the sinter-roasting.
