Patent DE-3536155-A1 (DE)
Title: Chamber furnace with gas circulation
Inventor: SCHMETZ PETER
IPC: F27D7/04
Filed: 1985-10-10
Abstract: The chamber furnace serves for the heat treatment of metal workpieces by means of convection. In order to avoid if possible, especially in a treatment space of relatively great length, temperature differences between its ends, the gas flow in the treatment space is from time to time reversed. To generate the gas flow, there is provided at each end of the chamber furnace at least one blower (12, 12a), which blowers alternately give rise to gas flows in opposite directions. To this end, shut-off and regulating members (15, 16 or 15a, 16a) are provided, with which in each case one of the two blowers (12 or 12a) can be connected into the flow circuit. The blower (12 or 12a) which in each case is excluded from the circuit remains in operation during the entire treatment time so that by merely actuating the shut-off and regulating members (15, 16 or 15a, 16a) the flow direction inside the treatment space (7) can be reversed in a very short time. Additionally, with the aid of the shut-off and regulating members (15 or 15a), the flow speed in the treatment space (7) can be changed. <IMAGE>

Title: Deep fat fryer
Inventor: GEROLD CHRISTIAN
IPC: A47J37/12
Filed: 1985-12-04
Abstract: It is proposed to construct a container for deep fat frying products, which container can be lowered into a deep fat frying bath and can be raised above the latter, as a filter pan, its upper edge extending in the fully lowered position over the surface of the deep fat frying bath. As a result, it is achieved with little production expenditure that crumbs dropping from the deep fat frying products do not pass into the bath surrounding the deep fat frying container and contaminate it. In particular, there are few parts to handle and clean. <IMAGE>

Title: Device for electrical indication and limit-value-monitoring of a non-electrical quantity
Inventor: HARTMANN RALF
IPC: G01P1/10
Filed: 1986-02-08
Abstract: In a device for the electrical indication and limit-value-monitoring of a non-electrical quantity having rotational-speed-dependent limit values, particularly for indicating and monitoring the oil pressure of an internal combustion engine of a motor vehicle, a transmitter connected to a crossed-coil measurement value (1), particularly a resistance-type oil pressure transmitter (2) outputs a transmitter voltage signal (UA(p)). This transmitter voltage signal is compared with a rotational-speed-dependent electrical signal (f(n)) in a comparator (3) in order to trigger a warning signal when the values drop below the rotational-speed-dependent limit values which are stored in the comparator. The rotational-speed-dependent signal (f(n)) is fed into the comparator (3) via a transmission element or a transducer (17) having a non-linear transfer characteristic. The transfer characteristic of the transducer matches a non-linear output characteristic of the transmitter (2) connected to the crossed-coil measuring mechanism (1).

Patent DE-3614636-A1 (DE)
Title: Winch arrangement
Inventor: KUPCZIK GUENTER DIPL ING
IPC: B66D1/74
Filed: 1986-04-30
Abstract: A winch arrangement on a frame has a driven storage drum and a two-sheaved capstan system, of whose sheaves one is driven and from which the rope is fed to the storage drum via a displaceably arranged deflection-pulley arrangement (14-16). The storage drum (5) and the capstan system (4) are arranged in regions next to each other. The displacement for the deflection-pulley arrangement with regard to the storage drum is effected on the winch arrangement in such a way that the rope is fed to the storage drum (5) with an approach angle which causes the windings to be automatically placed against one another without squeezing from rim to rim of the storage drum. For the displacement, the deflection-pulley arrangement is extended and fixed in the extended state in order to set, among other things, the distance between storage drum (5) and deflection pulleys (15, 16), guide passages (10, 11) being arranged on the frame (1) for this purpose. <IMAGE>

Title: Spray gun for liquids, in particular paints
Inventor: SULZ HANS
IPC: B05B9/01
Filed: 1986-07-01
Abstract: A spray gun for liquids, in particular paints, is proposed, which has a supply tank (13), a housing (10), a conveying device pumping the liquid from the supply tank (13), via a spring-loaded outlet valve (17), to a spray nozzle (21) and a return line connecting the outlet of the outlet valve (17) to the supply tank (13) and having a further adjustable valve (23). The conveying operation can be initiated by means of a switch-on device (12) arranged on a handle (11). For adjusting the further valve (23), an adjusting element (24) which is decoupled from the switch-on device (12) and automatically locks, infinitely variably, in any position is provided in the front spraying region of the spray gun. By this means, the spray jet can be easily varied as required during the spraying operation, a uniform spray cone still being obtained even with very low spraying densities. <IMAGE>

Title: Exchangeable heating beaker
Inventor: BEHR JUERGEN
IPC: B01L7/00
Filed: 1986-08-21
Abstract: In this invention, the bores of the commercially introduced heating blocks were developed for reasons of service improvement as "exchangeable holes". These heating beakers preferably consist of aluminium, are cylindrically elongate with the preferred diameters 41, 42 and 65 mm, have four different edge shapes depending on use, four preferred holding systems (base A, B, C and D) and two different basic base shapes, namely on the one hand the flat base and on the other hand the hemispherical round base (shape A and shape B). As a result, in the event of the glass breaking, it is possible to continue using the utensil, whereas previously it was sent in to the manufacturer for repair. The "hole" damaged by leaking acid is unscrewed, and a new heating beaker inserted. <IMAGE>

Title: Process and equipment for controlling the crystallisation process of fats
Inventor: REUNANEN OSMO ANTERO
IPC: B01D9/00
Filed: 1987-02-10
Abstract: The invention relates to a process for controlling the crystallisation process of fats, the crystallisation of, for example, margarine fats, butter fats, or chocolate fats generally beginning suddenly, after a high degree of supercooling, at a "defined" temperature, and at least one cooler (3) belonging to the crystallisation process in order to reduce the temperature of the fat and to begin the crystallisation process. The invention also relates to a plant system for carrying out the process. The crystallisation process of fat can be automated with the aid of the invention. By a process according to the invention the initial stage of crystallisation is directed principally into the uncooled flow section (10) downstream of the cooler (3) so that the temperature directly after the cooler (3) is established as the said "defined" temperature, so that this temperature or a corresponding parameter is measured, from which the cooling effect of the cooler (3) is controlled. Temperature measurement directly in the main stream after the cooler is difficult. Most advantageously, this temperature measurement, or measurement of a corresponding parameter, is performed with a measuring instrument (9) downstream of the cooler (3) already mentioned in a side stream (13) which is allowed to flow back to the main stream. <IMAGE>

Title: Method and arrangement for winding by means of a winding cassette the excess lengths of optical waveguides which are connected to one another
Inventor: DEUSSER PETER
IPC: G02B6/44
Filed: 1987-02-28
Abstract: The invention relates to a method for winding up the excess lengths of optical waveguides (LWL), which are connected to one another, by means of a winding cassette whose winding element is divided up by means of a laying duct in which the part of the optical waveguide which has the connection point is laid so as to extend essentially in an S shape. Orderly storage of the excess lengths is possible in a simple and space-saving manner in that excess lengths, starting from fixed points (1, 2), of the optical waveguides (3, 4) to be connected are dimensioned to be of approximately equal lengths, that the connection point (5) of the said optical waveguides is inserted into the laying duct (7), and in that, subsequently, with the excess lengths held in an extended position, the cassette (6) is rotated in order to simultaneously wind up the said excess lengths and, finally, the said cassette (6) is fixed in a predetermined position with respect to the fixed points (1, 2). <IMAGE>

Title: Tube with detachable continuous connection
Inventor: MAHLING ROLF DIPL CHEM
