Inventor: HORNSCHU JOACHIM
IPC: A45C13/30
Filed: 1984-05-24
Abstract: In order to secure a carrying cord or carrying chain to optical devices such as binoculars or cameras, a plug connection is specified which consists of a sleeve which is sunk into the device and of a plug which is secured to the carrying cord or carrying chain. The plug is elastically deformable in its radial direction, and can thereby be inserted into the sleeve via a constriction. It can be moved freely in the radial direction inside the sleeve, and its axial movement can be fixed in the sleeve by a lock. <IMAGE>

Title: Rocket drive for space flights
Inventor: SCHMIDT GUENTHER DR
IPC: F02K9/97
Filed: 1984-07-24
Abstract: A rocket drive for space flights, having a ground thrust nozzle and an altitude thrust nozzle, which can be adjusted in the axial direction and is located in a drawn-forward position during launching and flight at low altitudes, but in contrast is connected to the rear end of the ground thrust nozzle during flight at high altitudes. The ground thrust nozzle is designed as an overexpansion nozzle up to an altitude of approximately 12 to 14 km, and produces an exhaust pressure of approximately 0.2 to 0.15 bar. Up to an altitude of approximately 12 to 14 km, the altitude thrust nozzle is located in such a drawn-forward position that a second, outer thrust circle is produced, and in this case the rear region of the altitude thrust nozzle together with the radially inner ground thrust nozzle as well as its drawn-in central thrust jet, which drives the outer thrust jet by means of an injector effect, forms a convergent-divergent supersonic annular nozzle for this outer thrust jet. At an altitude of approximately 12 to 14 km, the altitude thrust nozzle is moved back and axially connected to the ground thrust nozzle. The altitude thrust nozzle is designed as an overexpansion nozzle with respect to the environmental pressure prevailing at the altitude of approximately 12 to 14 km such that it produces an exhaust pressure of approximately 0.03 to 0.02 bar.

IPC: B02C17/10
Filed: 1985-01-05
Abstract: In order to provide a device for destroying an inner structure of materials, in particular for embrittling materials made of cellulose-containing fibres, having two elements which are driven by a motor and operate counter to one another and have mutually facing pressure surfaces by means of which a pressure which is adequate for embrittling can be exerted on the fibres lying therebetween, which device is of simple design and operates reliably independently of the surface condition of the fibres, it is proposed that the first element be a chamber which can be made to oscillate by means of an eccentric driven by the motor and has at least one impact surface which serves as a first pressure surface and extends essentially transversely with respect to one direction of oscillation of the chamber, that the second element be at least one impact body which can move in the chamber and has at least one crushing surface serving as a second pressure surface and that the impact body have a mass which, together with a stroke and a speed of rotation of the eccentric, can be selected in such a way that the impact body beats against the impact surface once during each oscillation cycle and, in this process, destroys the inner structure of the fibres lying between the impact surface and crushing surface.

Title: Evaluating electronics for differential capacitors for use in sensors
Inventor: HABERLAND RUEDIGER PROF DR ING
IPC: G01D5/241
Filed: 1985-05-06
Abstract: The stability of the measurement value of evaluating electronics for differential capacitors with a pulse-width-modulated squarewave output voltage, in which the individual capacitors are alternately loaded via 2 independent resistors, the capacitor not loaded in each case being connected to earth potential, depends, on the one hand, on a stable squarewave voltage amplitude and, on the other hand, especially on the equality and the drift characteristics of the two charging resistors. This instability caused by the resistors can be prevented in this invention by using only one charging resistor which is connected to the capacitor to be charged in each case by means of a change-over switch. It is also found that the stability of the circuit does not depend on the quality of the charging resistor.

Abstract: An adjustable stator shell for eccentric-screw pumps comprises an interior steel sheet insert and a sprayed-on shell sleeve which encompasses the steel sheet insert axially and radially on the outside and is made of hard plastic. The steel sheet insert and the shell sleeve have slots and form two parallel tensioning bars having tensioning bores. In the region of the tensioning bores, integrally moulded-on reinforcement ribs are fitted on the outside of the shell sleeve, to ensure uniformly circular deformation of the stator shell during retensioning and simple handling and low weight of the stator shell.

Title: Wind power system with a compressor and compressed air storage
Inventor: MUELLER WALTER
IPC: F03D80/70
Filed: 1985-08-03
Abstract: Arranged on the vane ends of the rotor are axial compressors which are driven by propellers. The air is compressed and pressed through the vane spars (rotor tubes) and the tower bend via a tower valve into the tower at approx. 2 bars, where it is stored. The tower is a tubular construction and serves at the same time as a compressed air store. The turbine with generator is located away from the tower and is connected to the lower end of the tower via a compressed air line having a shut-off valve. The expanded and thus cold exhaust air can be used for obtaining fresh water from damp air or for room cooling. A plurality of independent wind power systems can operate a central turbine set. The compressed air can also be used directly to drive pumps, pneumatic equipment and machines.

Filed: 1985-11-27
Abstract: A rotary internal combustion engine of trochoidal type is described, which essentially comprises a housing, which is formed from an outer casing 2 with multiple-arced inner surface and side parts 4. In addition an essentially triangular rotary piston 3 is provided, which is arranged pivotably mounted on an eccentric 8 of an eccentric shaft 7 and is connected to a gear transmission inserted between it and the housing in order to obtain a certain speed ratio between the rotary piston 3 and the eccentric shaft 7.

Title: Trolley, in particular shopping trolley
Inventor: EBERLEIN HERBERT DIPL ING
IPC: G07F7/06
Filed: 1986-02-18
Abstract: The invention describes a trolley, in particular a shopping trolley (1) which is equipped with a coupling part (5). With the aid of this coupling part (5), the trolley (1) can be coupled in such a manner to a positionally fixed collection point (43) or to an identical trolley (1) which is likewise equipped with a coupling part (5) and is situated in front so that the two trolleys (1) are pushed one into the other. A trolley (1) can only be uncoupled by depositing a coin which is inserted into the coupling part (5) of the rear trolley (1). On returning this trolley (1) the coin deposited earlier on is given back after the coupling procedure. It has proven disadvantageous that in known systems shearing forces which occur when pushing a line of such trolleys (1) are conducted over the coupling parts and hence damage may occur to the coupling parts (5). The present invention avoids this disadvantage in that there is provided on the coupling part (5) a locking bar (15) which can be changed in its position and, with two trolleys (1) coupled together, then engages behind part of the trolley (1) in front without making contact when the two trolleys (1) are fully pushed one into the other. <IMAGE>

In order to mount the cover housing on the reflector (2), provision is made for a securing part (7) which is constructed as a twist (rotary) lock. The securing part (7) has a retaining section (39) for connecting the lamp bracket (4) with the housing cover (6), and a closing section (40) for connection with the reflector (2). The securing section (40) is screwed into a centring attachment (11) of the reflector (2), on which the plug housing (3) and the lamp bracket (4) are centred. The securing part (7) can be used to mount the lamp bracket (4) and the plug housing (3) in a simple way on the reflector (2) without giving rise to the risk of damage to luminaire parts. <IMAGE>
