Title: Reciprocating piston engine
Inventor: GOLDIN RUDOLF DIPL ING
IPC: F15B15/02
Filed: 1987-02-06
Abstract: The invention relates to a reciprocating piston engine for a liquid or gaseous working medium, with at least one piston performing a straight-line reciprocating movement in a cylinder, which piston in the cylinder separates a first piston chamber from a second piston chamber, and with a reversing device which, in the two limit positions of the piston, alternately connects a feed line for the working medium to the first or second piston chamber. In order to simplify the construction and improve the functioning, the following features are proposed:   a) the first piston chamber is connected to a first control chamber by way of a first flow line, whilst the second piston chamber is connected to a second control chamber by way of a second flow line; b) the two control chambers have a reversing valve, which in its one limit position in the first control chamber connects the said feed line to the first flow line and in the second control chamber connects the second flow line to a discharge line for the working medium at zero pressure, and which in its other limit position in the first control chamber interrupts the said connection between feed line and first flow line and at the same time connects the first flow line to the said discharge line and in the second control chamber interrupts the said connection between second flow line and discharge line and at the same time ...

Title: Device for skinning pigs
Inventor: BUCHNER DIETER
IPC: A22B5/16
Filed: 1987-05-14
Abstract: The invention relates to a device for skinning pigs which is of vertical design and is intended to be used in the slaughtering lines of slaughtering systems. The aim of the invention is to separate good-quality skin from the carcass while being able to cope with any skin thickness. The object of the invention is to develop a device which makes it unnecessary to adjust the distance between the cutting knife and the cutting roller on a constant or periodic basis and ensures that the adhesion of fat and the cracking of skin are avoided. According to the invention, the object is achieved in that the cutting knife is pivotably mounted on a mounting, four of which are arranged on a crossmember, and that below the cutting knife there is situated a knife which is for the subsequent removal of bacon and can be adjusted, together with the cutting knife, to set the cutting distance from the cutting roller, but which can also be adjusted independently. <IMAGE>

Title: Opto-sensor control of the lights of a motor vehicle
Inventor: WIEGAND FRANK
IPC: B60Q1/14
Filed: 1987-11-04
Abstract: The dipped headlights of motor vehicles are still switched on today manually which involves a certain hazard for traffic and inconvenience for the driver of the motor vehicle. The invention presents an automatic system which assumes the function of switching the travel lights on and off as a function of the external light, in particular sunlight. For this purpose, the external light is tested by means of a photodetector for the presence of a specific wavelength which hardly occurs in artificial light. If the intensity of this light drops below a specific value, a switch-on delay is actuated which itself switches on the dipped headlights after approximately 5 seconds by means of a relay. If the intensity rises again above a value, the light is switched off with a delay of approximately 28 seconds. The delay is necessary to avoid the electronic system switching erratically on and off. The invention is intended as a new item of basic equipment for series production in the car industry.

Title: Electrical absorption circuit for influencing the electrical climates in high buildings with respect to building biology
Inventor: ROSKE ERICH
IPC: H03H5/02
Filed: 1987-11-27
Abstract: In a spherical cavity resonator between the earth's surface and ionosphere having the natural frequency of about 7.8 Hz, resonant electromagnetic oscillations occur which have a spectrum of harmonics up to about 20 Hz. These so-called atmospherics are excited by thunderstorm discharges and electron currents from the surface of the sun. They generate bioelectrical reactions in humans by synchronising the alternating brain currents. According to the invention, a damped electrical absorption circuit having a resonant frequency of 13 Hz and a bandwidth b3db = 500 Hz is specified, the wire loop of which is run on the top floor of a house and which results in significant attenuation of the atmospherics.

Title: Process for removing iron(III) from acid zinc salt solutions by solvent extraction
Inventor: POPPE WILHELM DR RER NAT
IPC: C01G49/00
Filed: 1988-01-20
Abstract: Iron(III)-containing acid zinc liquors are, to separate the iron(III) ions from aqueous acid zinc liquors, treated with primary aliphatic amines and an organophosphonic monoester which functions as extraction agent. The solvent loaded with iron(III) ions is subsequently freed of accompanying metallic impurities and of iron(III) ions in two re-extraction steps by treatment with mineral acids or with aqueous solutions of the salts of such mineral acids. The organic phase purified of iron(III) ions is then again used for extraction. From the iron(III)-enriched re-extraction solution, an iron(III) compound can be obtained by a drying process or hydrolysis reaction, with the solution freed of the iron(III) compound being regenerated for multiple use in the re-extraction.

Title: Supporting bearing arrangement of a gear unit in a ship
Inventor: MERK KARL-HEINZ ING GRAD
IPC: B63H21/30
Filed: 1988-06-09
Abstract: Supporting elements (24, 26), which are effective in parallel but one after the other, have different spring rigidity. Here, the supporting element (24) with the higher spring rigidity only comes into effect when the supporting element (22) with the smaller spring rigidity has already been compressed by a certain amount of travel by the gear unit, due to the weight of the gear unit and a minimum of resulting torque of the gear unit which is transmitted by the gear unit (4) to the ship's foundation (20). Thus a considerable reduction in impact sound preferably in the lower torque range and at the same time positional stability of the drive shaft (8) and the output shaft (12) of the gear unit (4) in the higher torque range are achieved. <IMAGE>
