Title: Continuous and batchwise partitioning appliance for suspensions and bulk solids
Inventor: MUELLER HELMUT DIPL ING DR ING
IPC: G01N1/20
Filed: 1984-10-08
Abstract: The invention relates to an appliance for continuous and batchwise partitioning of suspensions and bulk solids for the purpose of accurate characterisation of the states of systems of materials. The purpose and the objective of the invention is to describe an apparatus which makes it possible to achieve the partitioning of suspensions and bulk solids without elaborate conversion work, to achieve high throughputs and to partition with high accuracy. To this end, the suspension is fed via a stirred vessel having an outlet orifice, or the solids to be tested are fed via a vibrating chute, to the rotating partitioning apparatus. The in-feed is effected by placing the sample material on to the cone tip located inside and moving with the partitioning crown. This is done to homogenise the sample material and to avoid any size reduction. Via a slip plane the material reaches the sample orifices located in the partitioning crown and, in the case of batchwise operation, drops into the 8 removable sampling containers arranged below these. After partitioning has been effected, the required sample can be withdrawn or further processing can be carried out in order to obtain the desired sample size. According to the same operational scheme, partitioning can also be carried out continuously. The partitioned sample flows directly into corresponding collection vessel with outlet orifices. The invention can be applied in process manufacturing laboratories and in chemical and food industry laboratories.
Patent DE-3438192-A1 (DE)
Title: Method and apparatus for producing an envelope for dispatch
IPC: B31B50/00
Filed: 1984-10-18
Abstract: In a method for producing an envelope for dispatch, a coloured glue is used. Once the glue has been applied to predetermined regions of the envelope blank, the said region is scanned by a photoelectric cell, which is sensitive to the wavelength range of the colour of the dye. If the measuring cell emits a signal, this indicates that sufficient glue has been applied. If there is no measuring signal, on the other hand, a warning signal is emitted, which stops the production machine.

Title: Motor fan unit, especially for vacuum cleaners
Inventor: MUELLER REINER DIPL ING
IPC: H02K7/14
Filed: 1984-11-29
Abstract: The invention is used during the production and assembly of the basic elements of a motor fan unit. The aim of the invention is to design the structural construction of a motor fan unit such that said construction complies with the requirements of automatic manufacture, without functional limitations, by means of a minimum number of assembly steps. The object of the invention is to create a detachable connection of the stationary framework parts of an electric motor, especially of a motor fan unit, which connection saves space and material and can be operated without using special assembly aids and without the corresponding technological cost. According to the invention, the object is achieved in that the completely installed housing and rotor assemblies are joined in the axial direction, are centred with respect to one another by means of an edge, and are connected to one another in a force-fitting and positively-locking manner such that overlapping elastic elements are arranged at the points at which the two assemblies abut. <IMAGE>

Title: Evaporator for a cooling device, in particular for a refrigerator
Inventor: BLANKEN DIETER ING GRAD
IPC: F25B39/02
Filed: 1985-02-02
Abstract: An evaporator for a refrigerator with a freezing compartment and a refrigerating compartment has a first and second evaporator part. The first evaporator part is U-shaped with two walls and a transverse wall which partially surround the freezing compartment. The first evaporator part is connected to the second evaporator part via a connecting web which is designed in one piece with the two evaporator parts and is a part which is partially separated from the first evaporator part. The evaporator parts have refrigerant ducts on the outside of the evaporator parts, which are manufactured together with the connecting web from a plate. The connecting web is partially separated from the lower wall of the first evaporator part so that the refrigerant ducts lie on the same side in relation to the original plate. As a result, the surface of the upper wall of the first evaporator part is not reduced in size by the separation of the connecting web so that, in the installation position, the freezing compartment can be cooled optimally in the region of the ceiling. Moreover, the original plate does not have to be used for arranging the refrigerant ducts so that the manufacture of the evaporator can be carried out in a considerably simplified and economical manner.

Patent DE-3523826-A1 (DE)
Inventor: GELLERT JOBST ULRICH
IPC: B23P15/00
Filed: 1985-07-03
Abstract: This invention relates to an improved heated nozzle for injection molding and an improved method of manufacturing it. The nozzle has an elongated body with a melt bore extending generally centrally through it. The cylindrical outer surface of the body has a variable pitched spiral channel extending around it along its length. A helical electric heating element is embedded in the channel to form an integral structure by which the temperature of the hot melt can be maintained within a narrow range as it flows through the bore. The nozzle is manufactured by forming the body with the channel and bore either by investment casting or machining. The heating element is wound in the channel and a bead of nickel brazing paste is run along the top of it. The nozzle is then heated in a vacuum furnace to braze the heating element in the channel. The highly conductive nickel completely covers the heating element and is fused to both the heating element and the walls of the channel. Thus, a low cost integral nozzle is provided which during use efficiently dissipates heat from the element to prolong its effective life, and applies the heat uniformly along the melt bore.

Patent DE-3529532-A1 (DE)
Title: Hagen twin-wheel marine propulsion
Inventor: HAGEN MARTINA
IPC: B63H1/08
Filed: 1985-08-17
Abstract: The twin-wheel marine propulsion is intended to replace the inefficient propellers and to fully apply the input energy. During a shaft revolution, 12 wheel blades convert the input energy without great losses and without turbulence into thrust force. Greater speeds are achieved at the same engine output as before or lower engine outputs are required at the same speed as before. The turning circle of the ships is optimally reduced, since the steering is effected by the two twin-wheel marine propulsion systems in combination with the rotatable bearing-block lining. The twin-wheel marine propulsion only rotates clockwise. Forward and astern travel is achieved by the adjustment of the reversal point of the twin-disc bodies, which reversal point can be rotated through 180 DEG  in the horizontal axis. The reversal of the individual blades through 90 DEG  is carried out via a twin-disc body which has 2 opposite reversal points.

Title: Automatic maritime search and rescue radio direction finder
Inventor: WAECHTLER MAXIMILIAN DR
IPC: G01S3/14
Filed: 1985-09-30
Abstract: The method for automatic emergency radio direction finding is used for continuously monitoring at least one of the maritime search and rescue frequencies and for automatically triggering a storage process when an emergency call is received. During this process, the bearing signals of the emergency call, detected in accordance with the dual-channel principle, are completely recorded and subsequently evaluated for determining the bearing direction. To record the complete bearing information means that the bearing signal is detected and stored during the entire period of transmission of the emergency call. This has the advantage that the entire transmission can be reproduced again at any time like a stored television transmission. During this process, the best results with respect to direction finding can be selected in each case for the evaluation of the bearing direction. Bearing results which, due to propagation conditions, can be used only incompletely or not at all for evaluation can be disregarded in this method.

Title: Device for controlling a hydraulic piston rail brake
Inventor: SCHMALL JUERGEN DIPL ING
IPC: B61K7/12
Filed: 1986-02-10
Abstract: In order to limit the pressure within the hydraulic system (HS) of a piston rail brake, a plurality of excess pressure valves (UV1, UV2, UV3) which are set to different pressures are provided. The valves, with the exception of the valve (UV3) which is set to the highest pressure, are located in series with hydraulic switches (SU1, SU2) which can be adjusted as required by a control device (SE1) in order to deactivate individual excess pressure valves (UV1, UV2). The limitation of pressure within the hydraulic system is necessary so that lightweight vehicles on the piston rail brake do not jump off the rails. In addition to the excess pressure valves, valves (V1, V2) which respond to different flow speeds of the hydraulic fluid may be provided, by means of which valves (V1, V2) the piston rail brake can be adjusted to different action speeds. In order to control these valves, hydraulic switches (S1, S2) are also provided, of which switches (S1, S2) only one may be activated in each case. The piston rail brake is to be deactivated as required by means of a further hydraulic switch (SR). <IMAGE>
