Inventor: RAUBE WOLFHARD
IPC: F25B47/02
Filed: 1983-02-23
Abstract: According to the invention, the hot, gaseous refrigerant compressed by a compressor is fed to the evaporator, bypassing a condenser arranged in the refrigerant circuit and an expansion element situated between the condenser and the evaporator. According to the invention, the high pressure side of the compressor is connected to a duct which can be shut off, which bypasses the condenser, and which opens, after the condenser, into the duct connecting the condenser to the evaporator. Moreover a bypass duct, which can likewise be shut off, is provided for the expansion element, the shut-off valves provided in these ducts being opened for the defrosting operation.

Title: System for transporting solid materials in pipelines by means of liquid or gas transport media
Inventor: BOJAK KURT DIPL ING
IPC: B65G51/02
Filed: 1983-03-05
Abstract: For transporting in pipelines using a liquid transport medium, for example water, or a gaseous transport medium, for example air, the solid materials, for example coal or ore, occurring in the form of lumps, are first crushed and then combined, preferably by means of pressing using a binding agent, into uniform compact units of material, for example in the shape of balls or cylindrical bodies. The streamlined shaped bodies are introduced into the transport pipe by means of special devices and are moved forward in the pipe by the transport medium with a relatively low expenditure of energy in a rolling, sliding or floating manner. It is then a simple matter to separate the solid material from the transport medium at the destination and output station.

Title: Device for cooling film webs, in particular for plastics processing machines
Inventor: DOEKE ROLF DIPL ING
IPC: B29C48/08
Filed: 1983-04-06
Abstract: The invention relates to a device for cooling, such as are used as downstream devices on calenders and extruders. The aim of the invention is to reduce the outlay for apparatus and to improve the quality of the film produced. The invention is based on the object of providing a device with which the film is cooled slowly and uniformly and the operating temperature is already present in the start-up phase. This object is achieved in that the cooling rolls are arranged on the cooling fluid side individually or in pairs both within a roll group and between the roll groups such that all consecutively counted even-numbered cooling rolls and all odd-numbered cooling rolls are connected to one another in series by cooling-fluid pipe connections and a connection pipe. For preheating before start-up of the system, heating-up lines which can be sealed off are arranged between the cooling-fluid supply pipe and the cooling-fluid discharge pipe. The device according to the invention is used for cooling film webs, in particular for plastics processing machines.

Title: Maize chopper having a friction floor
Inventor: REBER ERWIN
IPC: A01F29/09
Filed: 1983-05-04
Abstract: The diagrammatically illustrated cutting unit of a drum-type chopper for silo maize harvesting has a chopping drum 3 which is driven to rotate in a housing 1 and the cutters 2 of which cooperate with a countercutter 4 fixed to the housing. For a fine comminution of the maize grains supplied, a friction floor 7 consisting of a plurality of identical parts 7', 7'' and 7''' is arranged in the chopper housing. The friction-floor parts 7', 7'' and 7''' are interchangeable in their installed position and can also be installed rotated through 180 DEG . It is thereby possible to bring the friction-floor parts which are at the front in the conveying direction of the stream of material to be chopped and which are subject to high wear into a position not impairing the comminuting work and to replace them with friction-floor parts which are not yet worn. <IMAGE>

Title: Control device for computer flashguns in the macro range
Inventor: LEYH GUENTER ING GRAD
IPC: G03B15/05
Filed: 1983-06-21
Abstract: The control device consists in principle of filters which are connected upstream of the measuring cell of the flashgun and which attenuate the measuring beam reflected from the object. As a result, the computer makes more light available and thus balances out the higher light requirement caused by the lengthening of the extension or otherwise. The shooting aperture selected in the computer flashgun and set on the camera is either maintained or can instead be modified as required. Moreover, the parallax between the flashgun reflector and measuring cell is balanced out by means of an upstream positive lens. The flash control of any computer flashgun can also be used in the macro range with the aid of this control device.

Title: Binary material window cage for antifriction bearings, especially roller bearings
Inventor: ALBERT MATHIAS DIPL ING DR
IPC: F16C33/56
Filed: 1983-06-24
Abstract: In the case of a binary material window cage for antifriction bearings, especially roller bearings, with a cylindrical sheet metal shell equipped with windows in which the rolling elements are arranged, which engage between the rolling elements and are composed of a material with sliding characteristics superior to those of the sheet metal shell, it is proposed in each case to provide two webs (5) lying opposite one another at an axial interval and to join the webs (5) on each side by a ring (4) which is either inserted on the end face into the sheet metal shell (1) or encloses this. The rings with the webs can be simply manufactured, for example from plastic. This results in a completely symmetrical cage without any risk of fracture for the webs and a good roller guide. <IMAGE>

Title: Device for fixing assemblies

Patent DE-3336741-A1 (DE)
Title: Edge sensor
Inventor: KRAUTH WOLFGANG
IPC: B65H23/02
Filed: 1983-10-08
Abstract: The invention relates to an edge sensor for scanning the edge of a web of material, having a pivotable sensor arm which is connected to a switching device which can be actuated for the emission of at least one signal when the sensor arm is deflected. In known mechanical edge sensors, the sensor arm actuates electrical contacts or pilot valves through which signals are then generated. This is disadvantageous in that the sensor arm must exert a certain amount of force if the switching devices are to be actuated and in addition there is reduction or exaggeration of the stroke or force between the region in which the sensor arm rests against the edge and the region in which it actuates the switching device, unless the sensor arm is extended a very long way beyond its pivoting axis, which is also unfavourable. According to the invention, this is avoided by making the sensor arm support a metal element and giving the switching device an electrical proximity initiator which is arranged next to the path of motion of the element and works with the element in a contact-free manner.

Patent DE-3347833-A1 (DE)
Title: Device for continuous polarimetric measurement of the angle of roll of a movable machine part
Inventor: SCHUESSLER HANS-H DR ING
IPC: G01B11/30
Filed: 1983-06-24
Abstract: The invention relates to a device for continuous polarimetric measurement of the angle of roll of movable machine parts which are moved along a preferably rectilinear line of movement. Specifically, polarised light having a defined direction of polarisation is emitted in the direction towards the machine part. Arranged on the movable machine part is the analyser, which also executes the rolling movements of the machine part. Arranged behind said analyser is either a light detector or a reflector, which retroreflects the analysed light onto the light source; in the latter case, the light detector is activated via an inclined, partially transmitting mirror which can form a module together with the light source. The direction of polarisation of the emitted light beam can be varied by a Faraday modulator in order to compensate the angle of roll which occurs. For the rest, the direction of polarisation can be caused to oscillate at high frequency about a central position in order to increase the measurement accuracy, the output signal at the light detector being evaluated in terms of its harmonic components. In order also to carry out a straightness measurement together with the measurement of the angle of roll, the photodiode is designed so as to be sensitive to the beam position in terms of elevation and azimuth.
