Patent DE-3325733-A1 (DE)
Title: Reheating furnace
Inventor: SCHATSCHNEIDER PETER
IPC: F27D3/02
Filed: 1983-07-16
Abstract: In reheating furnaces for establishing the rolling temperature of workpieces, with a furnace space within which are arranged cooled support tubes to receive the goods to be reheated and sliding devices being provided on the support tubes, the problem exists that strip-shaped cool shadows are formed in the goods to be reheated, since the goods to be reheated rest on the support tubes always with the same spot during their travel through the furnace, and thus heat does not reach these spots. Considerable losses of quality in the succeeding rolling stage are connected with this. To solve the resulting object, the support tubes are arranged obliquely with respect to the longitudinal axis of the reheating furnace. <IMAGE>

Patent DE-3336752-A1 (DE)
Title: Method for drawing off powdered or granular products
Inventor: SCHNABEL HELMUT
IPC: B65B1/46
Filed: 1983-10-08
Abstract: In the drawing off of powdered or granular products, metering by volume is frequently used. For this purpose, a predetermined measured volume is filled with the powdered material and then emptied into a container provided for reception and packaging. The fluctuations in the filling weight which occur in this process can be reduced if filling weight monitoring is carried out based on measuring the microwave absorption of the filled containers and using it as a measured value indicating the filling weight. Containers which are outside the predetermined filling weight tolerances can be automatically removed by a sorting apparatus controlled by the microwave signal. The microwave signal used is the quality factor alteration of a resonator into which the containers filled with the product are intermittently inserted. If higher levels of metering accuracy are required, the microwave absorption of the empty containers is measured before the material is metered in. These absorption values are then used as reference values on which measurement of the respective filled containers is based. This type of metering has proved its worth especially in the drawing off of powdered substances in pharmaceutical production operations. <IMAGE>

Title: Garden composter
Inventor: MATTHISS FRITZ
IPC: C05F17/02
Filed: 1984-03-20
Abstract: The invention relates to a reinforced-concrete garden and environmental composter having a rectangular basic outline with four profiled corner posts, horizontal lamellae and connection of both parts by means of brackets, there being one bracket per corner. The predetermined form of this garden composter (1) permits very good composting of all garden and household refuse since, as is the case with all concrete products of this type, it is highly resistant to all corrosive substances, in particular to household refuse, and, being set up in the open in most cases, it is also highly weather-resistant. By a symbiosis between the material and the design of the composter it is, on the one hand, very attractive and, on the other hand, the profilings can be used very advantageously and expediently for the garden composter (1) and the purposes it serves. For example, the lamellae (3) with their wavy profiles are very particularly suitable for producing variable ventilation openings which can be themselves the size of a lamella (3) or else only be round holes. In addition, a profiling of this type can produce other forms which go beyond composting refuse. In order to produce the type mentioned in the introduction, however, it is necessary that the posts (2) have brackets (4) on their side faces, which brackets effect connection to the lamella (3). The bracket (4) is fastened on the inner side of the lamella (3) and spaced apart from the end of the latter by the width of a post ... Original abstract incomplete. <IMAGE>
