Title: Furnace control
Inventor: HOFFMANN HEINFRIED DR ING
IPC: F23N3/04
Filed: 1981-08-05
Abstract: The furnace control serves for controlling the forward-run temperature of heating boilers with an expansion thermostat (30) which can be influenced by the boiler temperature and which, via a lever linkage (8, 8') and a chain (9), actuates the air flap (10) of the furnace of the heating boiler (111) against the action of a weight or spring force. Superimposed on this thermostatically controlled actuation movement of the air flap (10) is a further actuation movement which is controlled by an electric servomotor (12) depending upon another influencing variable, e.g. the setting in operation of an additional auxiliary boiler. <IMAGE>

Title: Process for producing a flour additive from maize or related cereals
Inventor: FRITZE HARTWIG DIPL ING
IPC: A23L5/20
Filed: 1981-08-25
Abstract: A flavour- and colour-neutral flour additive is produced from maize or related cereals, which additive can be added in particular to wheat flour in substantial proportions. In the process, the milled raw material is suspended in a polar solvent, preferably ethanol or isopropanol. In this case, an extraction takes place at a temperature in the region of the boiling point of the solvent, by which proteins and lipids are extracted from the material and the prolamine component is completely extracted. The treatment also simultaneously adjusts the dough-formation properties of the flour additive to those of the wheat flour.

Patent DE-3203446-A1 (DE)
Title: Quick-acting clamping device for workpieces
Inventor: LUTZ EUGEN
IPC: B23D47/04
Filed: 1982-02-02
Abstract: The invention describes a quick-acting clamping device for workpieces, in particular for plastic or light-alloy sections, which are to be drilled, sawn, milled or punched, by means of which pressing cylinders actuated by pressure medium can be set against the workpiece. According to the invention, the retaining bars to which the pressing cylinders are fastened are passed through between two clamping shells which can be held in a freely movable manner on a fastening bolt next to the work rest and can be pressed against one another via a pressing device. It is thus possible to set the retaining bars against the workpiece in various locations with only one manipulation by pivoting the clamping shells relative to the fastening bolt and by varying their height relative to the clamping discs, which previously required at least two manipulations at two clamping devices. The relatively large amount of material and the relatively high material and manufacturing cost associated with this as well as the time needed for setting the pressing cylinders are thus considerably reduced.

Title: Influencing the boundary layer of fluid-dynamic active surfaces
Inventor: RAEHMER HANS
IPC: B63H1/28
Filed: 1982-03-23
Abstract: In order to reduce the induced resistance of fluid-dynamic active surfaces (1) such as wings or propeller blades, laminarised (= stabilised) fluid flows (10) are ejected at their surfaces, preferably at their trailing edges, e.g. alternatively at the top side and underside of a wing (1). The method and device produce laminarised and undulating enveloping and/or outward flows (5), by means of which the boundary layers, which are otherwise presently usually turbulent and separating from the surfaces, are applied in a laminar fashion to the surfaces enveloped by the flow. The efficiency of such an arrangement is improved by devices for laminarising flow media, including CAONDA surfaces. <IMAGE>

Title: View-blocking noise protection wall
Inventor: BRUENEMANN HELMUT
IPC: E01F8/02
Filed: 1982-09-30
Abstract: View-blocking noise protection walls in areas requiring protection against noise are mostly cast from concrete. Not only are these walls expensive in terms of construction but they also destroy the landscape since they are simultaneously intended to form boundaries for pieces of land. The view-blocking noise protection wall according to the invention consists of individual structural elements which are formed by two plastics mouldings which are spaced apart from one another. To form a connection between two spaced, parallel mouldings and also a connection between two superposed mouldings, use is made of a metal plug-in connection made in two parts, as a result of which a connection between the two parts of the plug-in connection and a connection between the superposed moulded elements are possible without using a tool. Angular webs are integrally formed on the longitudinal sides of each moulded element for the purpose of forming a channel in which plants can be placed. To compensate for the moisture content in the soil-filled gap between two moulded elements, apertures are provided in the wall of each moulded element. The view-blocking noise protection wall according to the invention is intrinsically still capable of sustaining vegetation even when the space between the moulded elements is filled with concrete, since appropriate plants can be placed in the spaces formed by the angular webs. <IMAGE>

Title: Device for the examination of the interior of body cavities with ultrasonic waves
Inventor: NAKADA AKIO
IPC: A61B8/00
Filed: 1983-03-15
Abstract: The invention discloses a device for the examination of the interior of body cavities with ultrasonic waves with which the operations necessary for introduction of an insert part into a body cavity and bending of a bending part (4) can be easily carried out by one operator. In an ultrasonic probe (1) an ultrasonic probe head (3) for emitting and receiving ultrasonic waves and a bending part (4) for bending the ultrasonic probe head (3) are connected to each other on the outer side of an elongate insert part (2) to be introduced into a body cavity, and a holding part (68) and an angle knob (122) for the bending part (4) are provided on the hand side in the back of the insert part (2), it usually being difficult to insert the insert part (2) into a body cavity when the holding part (68) and the angle knob (122) are provided in positions separate from the axis of the insert part (2) unless the insert part (68) is retained, so that bending is difficult. Therefore, in the invention the insert part (2) is designed in a position in the proximity of the axial direction of the insert part (2) and the angle knob (122) on the side face of the holding part (68) in such a way that it improves the bending function. <IMAGE>

Title: Control lever for caterpillar track vehicles
Inventor: WARDENIER WILHELM
IPC: B62D11/00
Filed: 1983-04-30
Abstract: The invention relates to a control lever for single-hand control of caterpillar-track vehicles, which lever can be swivelled forwards and backwards to vary the speed and in the transverse direction in order to drive around bends. Instead of the linkage guide which was usually customary hitherto, said lever has a connection to the actuation elements of the left-hand or right-hand drive which acts on one side only in the case of transverse swivelling, such that the swivelling effects in each case only affect the left-hand or the right-hand drive. As a result, the vehicle can be steered more precisely and the risk of incorrect operation and the resulting high degree of wear is eliminated.

Title: Accessory for an injection device
Inventor: DENT HUGH ROBERT
IPC: A61M5/31
Filed: 1983-05-14
Abstract: In order to keep the risk of infection at a minimum when a large number of animals are injected with the same needle, an injection gun having a sleeve surrounding the needle is provided. The sleeve comprises two telescopic pipes. A releasable plastic cap in which a sponge impregnated with a sterilizing substance is located is fixed on the free end of the sleeve. The cap is provided with a screw-off section which is connected with the remaining part of the cap via a thin-walled annular neck. This section is separated from the remaining part of the cap by unscrewing, so that an opening is formed in the end wall of the cap. This is followed by an injection procedure in which the end of the cap is put on the intended injection site, the two tubes being pushed into one another, so that the needle tip moves through the sponge and penetrates through the opening into the injection site. <IMAGE>
