Patent DE-3047360-A1 (DE)
Inventor: BOGNER ALBERT ING GRAD
IPC: H01H31/12
Filed: 1980-12-16
Abstract: A connecting block (1) having a block body on which pairs of contact pieces (3, 4) are arranged one behind the other in the longitudinal direction for holding in each case one NH fuse (6) has a plurality of switching flaps (9) which are used as support for in each case one of the NH fuses (6). Said switching flaps (9) are supported on the side walls (2) of the block body, the support, which interacts exclusively with one of the two end regions of the switching flap (9), having on the side walls (2) in each case one guide groove (19) in which a guide pin (18) of the switching flap (9) is guided during its pivoting movement, as well as in each case one rotating pin (16) which defines the position of the pivoting axis of the switching flap (9) on the side wall (2) and engages in a second guide groove (15). The rotating pin (16) is attached to the side wall (2), and the second guide groove (15) is constructed on the end region of the switching flap (9) with an extent which allows the distance between the NH fuse (6), which is attached to the switching flap (9), and the rotating pin (16) to be increased. Furthermore, the first guide groove (19) has a course which forces this increase in distance to occur during the pivoting movement of the switching flap (9) from the closed position into the open position. <IMAGE>

Patent DE-3107972-A1 (DE)
Title: Hygienic covering for the foot
Inventor: HERTEL REINHARD
IPC: A43B3/10
Filed: 1981-03-03
Abstract: Since, in hotel bedrooms, particularly in those with carpets, it is undesirable, for reasons of hygiene relating to the feet, to walk barefoot on the floor, and since travellers in many cases do not have slippers in their overnight baggage, a foot protection covering is proposed, which can be produced simply, and therefore inexpensively, and is intended for hotel bedrooms, and guest houses and the like. This hygienic foot protection covering consists essentially of a sole which is made of paper, plastic or the like and has, on the upper side in the area of the front of the foot, a strap consisting of two parts whose ends are displaceable relative to one another in the longitudinal direction of the strap. As a result of this, the foot protection cover can be packed away completely flat when not in use, without parts of the strap protruding laterally beyond the sole, while, in the use position, the strap is lifted up and thus lengthened. If, in addition, a cord of rubber-elastic material is guided through recesses in the parts and around these, the strap, in the use position, can be then lengthened counter to the spring effect of this cord and fits nicely on the foot.
Patent DE-3114262-A1 (DE)
Title: Earth collector of heat pumps and device for its manufacture
Inventor: WELTE ANTON
IPC: E02D7/16
Filed: 1981-04-09
Abstract: From a pit (22), earth probes (11-15) are driven in a stellar radial shape by a three-dimensional device which is guided longitudinally displaceably on a universally pivotably adjustable jib. Each earth probe (11-15) has an outer pipe (3) formed by individual screwed-together pipe lengths and an inner pipe (4) which is formed for example by a plastic tube and which in the case of the probes (11-13 and 15) is connected directly to the output distributor (19) of a heat pump (21), while the annular space between the two pipes is connected to the input distributor (18) by a connecting tube (6). The tubes (41, 42 and 61) make clear a series connection of the shorter and less deeply introduced earth probes (14, 15). Mounted at the free end of the outer pipes (3) is a displacement body (2) which has a slightly greater outer diameter than the outer pipe (3). The individual part lengths of the outer pipes (3) which are driven in by the three-dimensional device are connected by a slightly conical fine-pitch thread, the driving-in forces at one thread end being transmitted by a radial impact surface, while at the other end of the thread a contact is prevented and only a sealing ring is compressed in a given predetermined manner. <IMAGE>

Patent DE-3130621-A1 (DE)
Title: Fuel injection nozzle for internal combustion engines
Inventor: SEIFERT KURT
IPC: F02M61/18
Filed: 1981-08-01
Abstract: A fuel injection nozzle for internal combustion engines is proposed, which has a hollow needle (18), which is acted upon by the pressure of the fuel in its direction of flow and by a closing spring (60) in the other direction. In the hollow needle (18) a valve needle (70) is displaceably supported, which interacts with a valve seat (38) formed inside the hollow needle (18). A valve spring (84) and a stop (30) fixed to the housing are assigned to the valve needle (70), which stop restrains the valve needle (70) in relation to the hollow needle (18) moving in the opening direction, the valve thereby being opened. The closing movement of the hollow needle (18) is limited by a stop (58) on the nozzle body (10), which together with a counter shoulder (56) on the hollow needle suitably forms a seal on the combustion chamber side for the bearing gap between hollow needle (18) and nozzle body (10). This injection nozzle combines the advantages of a so-called I nozzle and a so-called A nozzle and has the further advantage that, due to the shielding of the bearing clearance between hollow needle and nozzle body, perfect guiding of the hollow needle is guaranteed for a long period. <IMAGE>

Title: Process for producing phosphoric acid
Inventor: ZOTOV BORIS GEORGIEVIC
IPC: C01B25/226
Filed: 1981-09-16
Abstract: The process for producing phosphoric acid provides for the decomposition of raw phosphate (rock phosphate) with sulphuric acid and phosphoric acid until a slurry is formed which contains the phosphoric acid and crystalline dihydrate or hemihydrate of the calcium sulphate, followed by the isolation of the end product from said slurry. According to the invention, the decomposition of raw phosphate is carried out with a mixture of sulphuric acid, phosphoric acid and part of the said slurry which is recycled to the decomposition stage, together with air in the form of a disperse system, the weight ratio of the disperse phase to the dispersant being from 1:0.09 to 1:0.16, or, to be fed in separately in the form of disperse systems, with a mixture of sulphuric acid and phosphoric acid with air, the weight ratio of the disperse phase to the dispersant being from 1:0.2 to 1:0.3, and said recycled slurry with air, its weight ratio being from 1:0.07 to 1:0.08, or with a mixture of sulphuric acid and phosphoric acid with air in the form of a disperse system, the weight ratio of the disperse phase to the dispersant being from 1:0.1 to 1:0.55.
Patent DE-3137349-A1 (DE)
Title: Device on vehicle trailers, in particular for the transportation of horses
Inventor: SIGG EDUARD
IPC: B60P1/43
Filed: 1981-09-19
Abstract: In the case of trailers for the transportation of horses, with a ramp (4) which can be swung down rearwards, there is the problem that the tension spring (2) for balancing the ramp weight, together with the rear end (13) of the side wall (9), bounds an opening (21) in which the hooves of the horses are easily caught. If a downwardly directed projection (3) is attached to the underside (6) of the ramp (4), a steeper position of the spring (2) with the dirt sleeve (15) results and the opening (21) becomes so narrow that accidents are ruled out. When partially raising the ramp (4), the lower attachment point (1) of the spring (2) being pivoted about the spindle (12), the lever arm of the spring (2) increases and hence also the action of relieving the spring of load increases and, as a result, the weight balancing of the ramp is improved. <IMAGE>

Title: Continuous process for applying a thin liquid layer and subsequently drying the latter
Inventor: GOTMAN ALEXANDER
IPC: B05C11/08
Filed: 1981-11-30
Abstract: In a process for applying a thin layer of a liquid material to a substrate, which is introduced into an atmosphere saturated with the vapour of a solvent for the coating material, the coating material is applied in the liquid state to the substrate and the latter is then rotated in order to distribute the coating material to form a thin layer, while the solvent atmosphere is retained. The substrate is then removed from the solvent vapour and heated in order to dry the coating. Equipment for carrying out the process comprises a drying chamber, a carrier for taking up the substrate, a rotary disc in the drying chamber for rotating the carrier with the substrate, means for generating the vapour atmosphere in the coating chamber and also a drying chamber which can be connected with and disconnected from the coating chamber, the chambers having openings through which they can be mutually connected. Means are provided for transferring the carrier from the coating chamber into the drying chamber and at the same time sealing the former tightly, so that, as far as possible, no solvent vapour can flow into the drying chamber. <IMAGE>

Patent DE-3210065-A1 (DE)
Title: Method and device for operating two slipring rotor machines
Inventor: LABER HANS DIPL ING
IPC: H02P5/56
Filed: 1982-03-19
Abstract: Two slipring rotor machines, whose running currents are in each case fed back into the supplying network via a six-pulse converter, generate intrinsically six-pulsed feedback effects on the network. However, a twelve-pulsed feedback effect is obtained in that the two machines are regulated via a speed regulator acting on the converter controller, in which the same desired speed value is input to each machine, but with an additional desired value to one of the two machines. The additional desired value is selected such that the slipring-side rectifiers of the two converters are operated with a relative phase shift of 30 DEG  electrical between them in each case. Preferably, an additional desired value is initially generated via a differential frequency regulator (26), which additional desired value forces identical speeds for the two machines. An angle differential regulator (16) is then switched on, to which the difference between the two rotor positions is applied and for which a desired value corresponding to the electrical phase difference of 30 DEG  is predetermined. The additional desired value ( DELTA n<'*>) formed by this angle differential regulator (16) forces phase-locked synchronous running of the two machines and hence the twelve-pulsed feedback effect. <IMAGE>

Title: Method and apparatus for testing and isolating rod-shaped articles in the tobacco processing industry
Inventor: WAHLE GUENTER
IPC: B07C5/36
Filed: 1982-03-26
Abstract: In the production of cigarettes, different characteristic properties are selectively tested in a test area (P2), i.e. different defect signals are generated, each corresponding to a type of defect. These defect signals are delayed until the cigarettes which have triggered them have reached an isolation area (A2). There, the defective cigarettes are removed from the path of the defect-free cigarettes and, at an isolation point - controlled by the defect signals - they are selectively, i.e. separately by defect types, transferred into collection receptacles, each of which is assigned to one type of defect. <IMAGE>

Title: Method and device for the technical use of solar energy
Inventor: PONTANI BERND
IPC: F24J2/00
Filed: 1982-10-04
Abstract: The invention relates to a method and a device for the technical use of solar energy. In the method, a primary energy transfer medium flows past a solar energy collector and absorbs energy from it. Subsequently, directly or indirectly, at least a part of the energy of the primary medium is transferred to a secondary medium. In order to manage, at least on the primary side, without auxiliary energies, e.g. by means of pump action, the air of the environment is used as primary medium. In terms of the device, this is achieved in that the air heated in the solar energy collector makes possible by its own convection a streaming after of colder air from a lower region.
