Patent DE-3426111-A1 (DE)
Title: Injection device for intramuscular injection of, in particular, insulin
Inventor: LINSS WALTER DIPL ING
IPC: A61M5/20
Filed: 1984-07-16
Abstract: It is the aim and object of the invention to design the slide which is displaceable in the longitudinal direction in the handle part of the pistol-shaped injection device such that reliable radial clamping and fixing of the axial position as a function of the injection syringe to be used are ensured. This makes it possible to use injection syringes adapted to suit the special requirements of the users and to permit exchangeability of different injection syringes having the nominal volumes required by diabetics. The object is achieved, according to the invention, in that tensioning jaws with prismatic clamping surfaces which have cams integrally formed below the axis are mounted on a common axis in the slide. A leaf spring presses against these cams and generates the radial clamping. At the front end of the slide there is located a stop and in the rear part there is located a stop angle displaceable in the longitudinal direction and lockable. This arrangement permits use of injection syringes having a diameter range from 8 to 12 mm and a length range from 55 to 65 mm.

Title: Adaptor for receiving double-grooved hammer drills in a toolholder, designed for triple-grooved hammer drills, of a hammer-drilling machine
Inventor: GEIS WILHELM DIPL ING
IPC: B23B45/16
Filed: 1984-09-15
Abstract: The subject of the invention is an adaptor for receiving double-grooved hammer drills, having a constant shank diameter irrespective of their helical diameter, in a toolholder (three-jaw chuck), designed for triple-grooved hammer drills, of a hammer-drilling machine. The object on which the invention is based is to find a way of using double-grooved hammer drills in a hammer-drilling machine equipped with a toolholder for triple-grooved hammer drills, which is simple and involves little cost and which does not adversely affect the functioning and/or handiness of the hammer-drilling machine. To achieve this object, the invention provides an adaptor which is designed as a sleeve (1) which can be pushed onto the respective shank of a double-grooved drill and is provided with three longitudinal recesses (2, 3, 4) distributed uniformly on the circumference and cooperating with the clamping jaws of the toolholder and which contains, at least in one groove, a radially resilient take-up element (7) fitting with an engaging effect into a groove (8, 8') of the double-grooved hammer drill. <IMAGE>
Patent DE-3437248-A1 (DE)
Title: Rail joint connection
Inventor: WETTSTEIN RENE
IPC: E01B11/54
Filed: 1984-10-11
Abstract: When rail or track sections are to be incorporated into an electric signalling circuit, these sections must be electrically separated by means of an insulated joint connection. The rail joint connection contains an essentially conical bolt (8), a cone sleeve (10), fixing nuts (12, 14, 16) and thrust washers (17). These elements are insulated in relation to one another and to the rail by intermediate insulating layers. The bolt (8) is guided through the conical bores (9, 11) in the fishplates (6, 7) and bores (5) in the rail web. The cone sleeve (10) lies over the thinner bolt section and a nut (12) fixes the bolt (8) and the cone sleeve (10) so that the fishplates (6, 7) form a rigid connection between the rail sections to be connected. Thrust washers (17) and nuts (14) bring about an increased stability of the joint connection. The cone-shaped sections of the bolt (8) and the cone sleeve (10) prevent play of the parts in relation to one another so that only a little wear arises. <IMAGE>
Patent DE-3440425-A1 (DE)
Title: Mast foot for a sailboard
Inventor: FLEMMING JOERG
IPC: B63B35/79
Filed: 1984-11-06
Abstract: The mast foot pivotably connects the rig to the sailboard about all three spatial axes. According to the prior art it is not possible to obtain quantitative statements about the spatial position of the rig relative to the hull. This object is achieved according to the invention in that the mast foot separates the spatial movement of the rig into the angular change about one to three of the spatial axes and in each case feeds it to an angle transducer. The angle transducers conveniently supply a voltage change, proportional to the angle, as an output signal for electrical data processing. The knowledge of the spatial position of the rig relative to the sailboard enables the Lilienthal polar diagram of the hull and the maximum total sail force to be determined by a new procedure, the reconstruction method (simulation of the total sail force during sailing in a land test). The knowledge of these two factors enables favourable underwater board geometry (in particular centreboard and fin surfaces) to be determined and the maximum board speed on the intended course to be estimated.

Title: Ashlar
IPC: E04C1/39
Filed: 1985-01-16
Abstract: The invention relates to an ashlar for erecting walls in which plants may be cultivated if required, which ashlar has elevations and/or depressions for locking to laterally adjoining neighbouring ashlars located thereabove or therebeneath. In order to achieve a longitudinal and lateral bonding, which can be highly loaded, of the ashlars, to permit handling by laypersons and to avoid accumulations of water or effects of drying out when cultivating plants, the ashlar according to the invention is shaped as a prismatic body having a U-shaped cross-section. The U-back is designed to be rounded and in the shape of a flat roof and has, halfway along its length on the inside, an eye-shaped projection with a central circular hole, while the U-legs which are rounded at the ends on the inside have, on the outside near the ends, a semicircular recess which runs from approximately halfway along their length to the vicinity of the U-back and is bisected in the longitudinal direction.

Filed: 1985-02-07
Abstract: Two sliding sleeves (14) are displaceably mounted on a long profiled tube (10), one of which is gradually adjustable along the rail (10) by means of latch pins, while the other is continuously adjusted by means of a screw spindle turned by a handle. Both sliding sleeves (14) carry transversely running clamping jaws and the latter are pivotable parallel to the profiled tube (10) in the plane defined by them. The novel screw clamp ensures that the clamping jaws set themselves as regards the angular adjustment and that they bear uniformly against the workpiece. Workpieces with boundary surfaces lying at an acute angle to one another can also be clamped. <IMAGE>
Patent DE-3507030-A1 (DE)
Title: Energy converter
Inventor: STROEBELE FRIEDRICH
IPC: F01B29/00
Filed: 1985-02-28
Abstract: Attempting to research the energy economy of environmentally friendly technologies, the basic principles were discovered in the science of statics. In order to set in motion a body at rest, points of support naturally absorbing two fundamental forces had to be determined and accommodated by the technology. In the present case these points of support are in a housing, which accommodated the part to be set in motion. The points of support rotate about the centre point and the centre of rotation - M -, which is also the centre of rotation of the rotating body (piston plate), and describe the same path as the body (piston plate) about - M - 360 DEG  and thereby attain their path to the starting point without having performed any reciprocal movement or having been exposed to any sliding friction resistance. The body (piston plate) is the object of a force field, which moves freely. Due to the action of stored hydromatic energy which occurs on the piston plate due to kinetically acting natural laws, a rotary movement is produced, thereby overcoming the moment of inertia and producing a translational energy.

Title: Electrohydraulic control device
Inventor: LEUTNER VOLKMAR DIPL ING
IPC: F15B13/04
Filed: 1985-03-01
Abstract: An electrohydraulic control device (10) is proposed in which two reciprocating drives (35, 39) uncoupled from one another act on a control spool (13) in such a way that, in a safety situation, the control spool (13) reaches a safety position (68) from the positions (63, 64, 65) allocated to a normal function without passing through intermediate positions. The control spool (13) has control grooves (24, 25, 27, 28) lying in a first plane (29) running through its longitudinal spool and fixed control ports (21, 22) which form first control windows (66) allocated to the normal function, whereas longitudinal grooves (31, 32) lie in a second plane (33) rotated relative to the first plane (29), which longitudinal grooves (31, 32) are allocated to the second control windows (67) for the safety function. The mechanism (38) converts the stroke movement of the releasing solenoid (39) into a rotary movement at the control spool (13) so that the second control windows (67) come into effect. Undesirable regulating movements caused by intermediate positions are therefore avoided when approaching the safety position (68). <IMAGE>

Title: Wind power stations and motors
Inventor: SCHMOLS KARL-HEINZ
IPC: F03D13/20
Filed: 1985-03-08
Abstract: So that wind and wind gusts are better utilised and do not destroy the stations, the stations are flexibly mounted on pendulum bearings. The wind roller mounting structure is fixed on a mounting mast on a base structure which is of immovable or even oscillating and rotatable construction, in such a way that the upper section leans back in the wind. As a result the station automatically turns to the wind. In the lower section, the movements of the wind roller mounting structure are controlled by weights, springs or by other devices. Owing to floating bodies in non-freezing liquids, can also be used in damp areas and also transportably. If compressed-air collecting vessels are used, compressors and also motors are needed which convert the compressed air back into torques. A chambered disc crank machine is ideal for achieving this, or a bellows-type piston machine, the joint-connected side plates folding into the pressure chamber and thereby improving the efficiency. The principle of these machines can also be used for internal combustion engines, if appropriate materials and additional ignition, fuel, lubrication etc. and cooling devices are used. Two or more motors of the same type should be combined to form one unit.

Title: Method for utilising the waste energy when milling cereal
Inventor: STEIN HERMANN
IPC: B02C11/08
Filed: 1985-05-28
Abstract: The invention relates to a method for effectively utilising the waste energy of the preprocessing and processing system of cereals, especially the heated air of the ventilators and pneumatic system of a cereal mill for the optimum preheating of the cereal and for partial feeding back of the mains water to the cereal in order to perfect a selective migration of water on and in the cereal grain, for better loosening of the husk from the seed and for mellowing of the endosperm. For this purpose, known devices are used, the warm air flowing directly around the cereal and, in this process, a conduction of heat and a compensation of moisture occurring without the known heat exchanger, heat pumps or heat pipes for energy recovery having to be used.

Title: Anti-skid chain for vehicle tyres
Inventor: HOHMANN WOLFGANG DIPL ING
IPC: B60C27/10
Filed: 1985-07-20
Abstract: The anti-skid chain is constructed as a quick-fit chain with a spring-elastic retaining bar (1a) as an inner holder (1) and a tensioning chain (4) which spans an intermediate space between the ends of the inner holder (1) according to the pulley principle. At the two ends of the retaining bar (1a), two deflectors (6, 7) are movably mounted, the second deflector (7) of which, guiding the tensioning chain (4) over the tread of the tyre, is mounted at the end of the retaining bar (1a) so as to be swivelable only in a stop-limited fashion in the plane of the bar whilst the rotary movement of the first deflector (6), lying opposite, about the axis (11), lying in the plane of the bar, of the retaining bar (1a) is stop-limited towards both sides. By means of this stop-limiting of the two deflectors (6, 7), the deflectors (6, 7), and thus also the tensioning chain (4) and the chain sections (3), which adjoin in the region of the ends of the retaining bar (1a), of the tread-covering network of the anti-skid chain cannot rotate beyond a predetermined swivel area when the chain is fitted over the vehicle tyre, as a result of which it is ensured in a simple and reliable manner that, after the retaining bar (1a) comes to rest against the inner edge of the tyre, both deflectors (6, 7) also rest flush against the tyre edge and as a result simultaneously cause the tensioning chain (4) also to be... from its attachment end (4b) at the second deflector (7) via the first deflector (6) and then back to the second ...
