Title: Method and device for manipulating bottles during filling and sealing
Inventor: SCHOTT HELMUT
IPC: B67C7/00
Filed: 1981-05-09
Abstract: A method and a device for implementing the method for manipulating upright bottles (11), which are conveyed one behind the other, during filling and sealing are proposed. In this process, a predetermined number of bottles (11) are removed from a bottle-feeding device (12) and moved into the region of a filling device (18). While these bottles (11) are being filled, previously filled bottles (11) are individually fed to a sealing machine (25). Empty bottles which are to be filled are moved up in accordance with the way in which the bottles (11) are fed in time with the sealing machine (25). When the filling process has been completed, the previously filled bottles are also fed to the sealing machine, and empty bottles which are to be filled stand on the bottle-feeding device (12) ready to be displaced into the region of the filling device (18). The filling device (18) is also displaced in a corresponding fashion, so that the filling process is carried out once on the right-hand side of the bottle-feeding device (12) and then on the left-hand side of the bottle-feeding device (12), looking in the direction in which the bottles are conveyed. The efficiency of such machines is considerably increased by this corresponding device, gentle treatment of the bottles (11) to be filled and, in particular of the bottles (11) which have been filled, being ensured. <IMAGE>

Title: Canopy comprising prefabricated parts
Inventor: JACOBSEN ROLF
IPC: E04F10/08
Filed: 1981-05-11
Abstract: The invention relates to a canopy comprising prefabricated parts with a plurality of mitred, identically profiled canopy-frame profiles consisting of lightweight metal, with corner connections, wall-fastening means, a canopy skin and a visible-underside directed towards the canopy-frame profile being provided, on its inner side directed towards the canopy skin, with an upwardly open and essentially U-shaped water channel, and with integrally formed protrusions so that supplementary profiles can be latched in. The object of the invention is to provide a canopy of the abovementioned generic type which, on the one hand, is distinguished by a stable, durable and sealed corner connection of its mitred canopy-frame profiles and, on the other hand, nevertheless ensures an aesthetically pleasing form, even if the visible-underside facing is transparent. This object is achieved according to the invention in that each corner connection comprises a shaped angle piece with two legs which enclose an angle of 90 DEG , can be introduced in each case into a cavity of the two adjoining canopy-frame profiles and then, by means of positively locking and/or frictionally locking connecting means which can be attached from outside, brace the end sides of the two canopy-frame profiles, at their common mitre joint, in a clamp-like manner with respect to one another. It is particularly advantageous if the corner connection is produced in two parts and comprises an upper and lower corner connection. In addition to the purpose for which it is intended, the invention can also be used anywhere where it is intended to brace cross-sectionally identically profiled lightweight-metal profiles to form as rigid and watertight a frame as possible.

Patent DE-3128243-A1 (DE)
Title: Pressure control in an installation for storing and dispensing very cold liquid media
Inventor: HESSE JUERGEN DIPL ING
IPC: G05D16/20
Filed: 1981-07-17
Abstract: In containers for storing and dispensing low-boiling liquefied gases, the pressure in the vessel drops when portions of the liquefied gas are dispensed. For the purpose of pressure compensation a small amount of the liquefied gas is therefore evaporated in an auxiliary pressuriser, is warmed to approximately ambient temperature and returned into the vessel. This measure, however, results in heat being supplied to the vessel at the same time, which leads, particularly in the case of a vessel which has already been largely emptied, to discernible heating of the remaining liquid. Depending on the internal pressure of the vessel, some of the liquid evaporates. In order to avoid these losses, the amount of liquid gas which has been evaporated in the auxiliary pressuriser (5) is not warmed to ambient temperature, but is returned, while very cold and in the saturation state, to the vessel (1). This is achieved expediently by arranging the servo valve (6) in the auxiliary pressuriser upstream of the evaporator (7) and by it being driven by the pressure in the vessel by mean of a controller. <IMAGE>

Title: Microwave orientation system for blind persons
Inventor: KLIR VILEM
IPC: A61H3/06
Filed: 1981-08-26
Abstract: The reliable orientation of blind persons in their environment has not yet been solved to date. Ultrasonic orientation systems are on offer, but they have a few defects:   a) low resolution, with the result that the range has to be limited to approximately 3 m; b) these systems are not noise immune, particularly in road traffic, which is subject to harmonics which fall in the ultrasonic range. Other methods have (so far as known) not yet gone beyond the trial stage. These problems have been solved according to the invention by applying a microwave system of high operating frequency (e.g. 24.1 GHz) for the orientation of blind persons. Fig. 1 shows the possible design of the system. The measurement of distance operates on the known monopulse principle. The microwave oscillations (e.g. 24.1 GHz) are produced in the microwave generator (2), modulated by the modulator (3) and emitted via the antenna (1). The echo from an obstacle is evaluated in the demodulator (4) and in the evaluation device (5), and converted in the VCO (6) into a tone. The pitch corresponds to the distance (e.g. 30 Hz = 0.3 m, 15 KHz = 15 m), with the result that the blind person can obtain a picture (up to 15 m) of his environment by swivelling the device. <IMAGE>

Title: Extruder for processing polymer materials
Inventor: KLOCKOV VLADIMIR IVANOVIC
IPC: B29C48/395
Filed: 1981-08-26
Abstract: The extruder for processing polymer materials contains a heated cylindrical barrel with a filling hopper, in the hollow space of which cylindrical barrel there are accommodated, coaxially, a rotating helical screw with, arranged one after the other in the flow direction of the material, a feed zone, compression zone and metering zone and a bush which surrounds the screw in the feed zone and has parallel helical grooves formed on its inner surface, in which grooves the direction of the turn of the helical lines is opposite to the direction of the helical line of the screw, the pitch of the helical line of the screw differing from the pitch of the helical line of the grooves. According to the invention, the pitch of the helical line of the bush grooves is less than the pitch of the helical line of the screw and is calculated according to the following relationship: <IMAGE> in which t2 represents the pitch of the helical line of the helical grooves on the inner surface of the bush; t1 represents the pitch of the helical line of @ the screw;  phi  represents the pitch angle of the helical line of the screw; K represents the ratio of the specific weight of the melt to the bulk density of the starting material; epsilon represents the degree of pressure loading of the screw.

Title: Piston internal combustion engine with variable compression ratio
Inventor: NOLTEMEYER FRIEDRICH
IPC: F01M1/08
Filed: 1981-12-05
Abstract: The compression ratio of a piston internal combustion engine is varied for adjustment to the instantaneous load during operation. For this purpose the piston pin of each piston is supported on a single- arm control lever, one end of which is supported in the small end bearing and the other end of which is acted upon by an articulated rod, which is connected to the control piston of a control cylinder formed by the connecting rod shank. The control piston is designed as a hollow body to which oil diverted from the lubricating oil duct of the connecting rod is fed. On the base of the control piston a non- return valve is arranged through which oil can overflow into the control cylinder. From this oil can flow out through a pressure regulating valve. The interaction of pressure relief valve and pressure regulating valve as a function of the load determines the volume of oil in the control cylinder, which in turn determines the position of the control lever and hence the compression ratio. An increase in the compression ratio improves the thermal efficiency, especially in the partial load range of spark ignition engines.
