Patent DE-3303907-A1 (DE)
Title: Apparatus for afterburning of flue gases
Inventor: SCHLEWITZ ARMIN
IPC: F24H1/28
Filed: 1983-02-05
Abstract: The apparatus of the invention is especially for lean gases from under-stoichiometric firings, such as wood gasifiers and combustion plants mainly fed with waste materials, a vortex chamber being fitted between the gasifier and the boiler (heat exchanger) for drawing in, vortexing, conveying and igniting the gases.

Title: Sports and/or playing field, in particular tennis court, a method for manufacture, and a powder mixture for producing a covering layer for such a court
Inventor: SCHRENK EBERHARD DIPL ING
IPC: C04B14/14
Filed: 1983-02-18
Abstract: The covering layer of a sports and/or playing field, in particular tennis court, is produced from a powder mixture which consists essentially of 5 to 25 % by weight of plaster binder and 75 to 95 % by weight of coloured naturally occurring stone, namely diabase (greenstones) and/or prasinite (green slate) as well as related facies, 5 to 20 % by weight of the powder mixture having an average grain size of less than 20  mu m. The stone preferably contains 5 to 30 % by weight talcum. The powder mixture is applied to a prepared superstructure, saturated with water and the water-saturated powder mixture layer is rolled. The sport-physiological properties, in particular however the ball bounce behaviour, correspond to those of conventional tennis coatings with brick-dust covering layer.

Title: Child-resistant protective cap for aerosol spray cans
Inventor: BOEH BERND
IPC: B65D83/14
Filed: 1983-11-26
Abstract: A child-resistant protective cap for aerosol spray cans is fitted integrally with two blocking strips which run diametrically and on both sides of the valve shaft below the spraying valve, supporting the latter. By pressure exerted on both sides of the protective cap in the direction of the blocking strips, the blocking strips can be spread apart and thus expose the spraying valve which projects upwards with a length which is sufficient for actuation through an opening formed in the protective cap. Additionally, the protective cap is provided with a lateral opening for the spray jet emerging from the spraying valve.

Title: Control device for a building board production plant
Inventor: SCHRELL GUENTER
IPC: B28B15/00
Filed: 1983-12-31
Abstract: There is a control device for a building board production plant, in which a feed device (2) for setting agent has an adjustable throughflow element (24) and a moulding device for forming a board structure from a mixture containing the setting agent is provided. The control device desired here is one which continuously measures the setting behaviour of the mixture for the board structure in a precise manner and without prejudicing the board structure and actuates the throughflow element for the setting agent as a function of this measurement. This is achieved by virtue of the fact that a first heat-radiation measuring head (11) at the moulding device (9) is assigned to the board structure, a further heat-radiation measuring head (12) is arranged at a distance behind the first measuring head, the two measuring heads act on a control unit (19) and this adjusts the throughflow element (24). The measuring heads operate continuously and non-destructively and the metering of the setting agent is continuously monitored and correctly set. <IMAGE>

Abstract: A process for the production of fried fish rolls from deep frozen sticks of herring fillets which are freed from the packaging casing at minus 3 degrees C, then sliced into uniform portions and fed in this state to wet and dry bread coating stations and frying stations and packaging stations. In this case the sliced portions or rolls are fed to a bath containing liquid multipurpose bread coating, composed of water, bread coating powder, dextrose and seasonings, are fed from there, after a residence time of 3-5 seconds to a vessel connected downstream and are coated in this with a multipurpose dry bread coating composed of water, starch, crude fibre, protein, minerals, table salt and spices. The rolls thus prepared are then fed to a thermostatically controllable oil bath designed for the frying phase, and are passed through the high-temperature oil bath by means of a link chain conveyor continuously circulating in an oil bath. The oil bath is equipped with a control thermostat for the oil temperature and a level controller for the particular desired oil level in the oil bath.

IPC: E06B3/48
Filed: 1984-03-29
Abstract: An intermediate profile (1) is arranged between in each case two adjacent folding-wall wings (20) or their vertical frame profiles (2) of a folding wall and is connected in a hinge-like manner to the frame profiles, the intermediate profile (1) serving at least for receiving hinge pins (14), cooperating with a respective hinge plate (15) on the respective frame profile (2), and either running rollers (10, 11) or locking means (7, 8). The intermediate profiles (1) are correspondingly at least approximately box-shaped hollow profiles which have, on their two narrow sides, inner profile projections (5%) for forming a respective hinge groove (5), receiving the hinge pins (14), and a central inner profile projection (6%) for forming a guide groove (6) receiving the carriers (11) of the running rollers (10) or the rods (7) of the locking means. These measures make it possible to have a folding wall which can be produced and assembled especially efficiently and therefore cost-effectively, can easily be folded together and unfolded, allows accident-free handling and, in the unfolded state, guarantees a high joint sealing even under the effect of pressure, for example caused by wind. <IMAGE>
