Title: Mouth gag for large animals
Inventor: WEINGART HANS DR
IPC: A61D15/00
Filed: 1987-09-19
Abstract: A mouth gag (11) for large animals comprises a maxillary bracket (12) and a mandibular bracket (13) which are articulated to one another and each have a cross-strut (16 and 19, respectively) by means of which the mouth of the animal can be opened by pivoting one of the two brackets (12, 13). In order to adjust the opening height of the mouth gag (11) at least one of the cross-struts (15, 19) is adjustably held in their longitudinal struts (bars 14, 15) extending in parallel with one another. Due to this design the mouth gag (11) can be used without any problems for different sizes of animal, and the mouth gag (11) is non-displaceably held in the oral cavity of the animal. Furthermore, the mouth gag is easy to produce and injuries to the oral cavity of the animal are virtually ruled out. <IMAGE>
Patent DE-3733554-A1 (DE)
Inventor: LOFGREN KARL M J
IPC: H03K5/13
Filed: 1987-10-03
Abstract: A circuit for providing precise delays includes a phase-locked loop driven by a reference frequency source such as a crystal oscillator 10 and including a variable delay circuit 12. The output of the oscillator 10 is applied to the delay circuit 12 and the non-delayed and delayed signals are compared in a phase comparator 16. An error signal representative of phase error is developed and applied to vary the amount of delay until the phase error is eliminated. A precise delay referenced to the oscillator frequency is therefore achieved. The delay line 12 is formed of series-connected CMOS inverter pairs. <IMAGE>

Title: Device provided for the connection of pipes or the like
Inventor: SUNNANVAEDER LARS
IPC: F16L27/08
Filed: 1987-11-06
Abstract: A description is given of a device which is provided for the connection of first pipes (1) to second pipes and is arranged, in the form of a union nut (9) with internal thread (14), rotatably and, via a radial outer protrusion (5), captively on the first pipe (1) and engages, by means of the thread (14), over at least one protrusion which projects radially outwardly at the end of the second pipe in the form of a female Luer cone. In order that the first and second pipes, which are interconnected in a sealed manner, can be rotated as required for the positioning of fittings, and the sealing connection is not released, even during rotation, the invention provides that a male Luer cone (15) is fitted concentrically on the inside of the union nut (9), the inner end of which cone opens in the perforated disc (10) at the base of the union nut (9), and that a securing means (11), which engages over the first pipe (1) with its radial, outer protrusion (5), extends from the perforated disc (10) in the direction counter to the Luer cone (15). <IMAGE>
Patent DE-3739289-A1 (DE)
Title: Device for injecting fuel into combustion chambers of internal combustion engines
Inventor: KOMAROFF IWAN
IPC: F23Q7/00
Filed: 1987-11-20
Abstract: With devices, the injection nozzles of which have a glow element in the form of a glow coil arranged at their outlets, through which the injection jets pass without making contact and, in the process, draw in air from the combustion chamber, there is the problem that materials for the glow coil wire which can withstand high thermal stresses and corrosive influences have only a limited mechanical strength and it may thus be necessary to support the glow coil in the case of high thermal and mechanical stresses. In order to make the glow coil (60) more rigid than an embodiment with a glow coil wire wound into the shape of a helical spring, the proposal is that the glow coil wire (62) should form a meander (64, 64a) which is shaped into a sleeve-shaped configuration. The preferred areas of application are in injection systems for diesel engines (Abstract Figure 2). <IMAGE>
Patent DE-3740670-A1 (DE)
Title: Pneumatic shock absorber
Inventor: STOLL KURT
IPC: F16F9/02
Filed: 1987-12-01
Abstract: A pneumatic shock absorber with a piston (10), which is displaceable in a cylinder (11) and has a piston rod (14) projecting therefrom, is proposed. Via a non-return valve (25) forming an inlet, a pressure space (12) in the cylinder (11), which is delimited by the piston (10), is connected to an external pressure source (P). An outlet duct (18) guided through the piston (10) connects the pressure space (12) to a second cylinder space (13) which is likewise delimited by the piston (10) and is connected to the outside air via at least one further duct (23). A seal (22) serves for interrupting the connection between the outlet duct (18) and the further duct (23) in a first stop position of the piston (10) which occurs at maximum pressure space volume. As a result, there are no pressure losses in the first stop position and in the opposite second stop position, the piston returns automatically to the first stop position in the unloaded state and the absorbing behaviour during the absorbing process is to a great extent continuous as a result of the flow cross-section in the outlet duct which is always the same. <IMAGE>
Patent DE-3801508-A1 (DE)
Title: Lubricant transfer from the machine spindle to the tool
Inventor: MILLER HERMANN
IPC: B23Q1/00
Filed: 1988-01-20
Abstract: The lubricant transmission or transmission of other media from the machine spindle to the tools is effected through the wall of the machine spindle, via the screw indentations of the driving blocks, to the tools, as the drawing shows. The driving blocks project beyond the machine spindle, with the result that the medium drips off in front of the spindle during the tool change and neither the tool receptacle of the spindle nor the receiving cone of the tool is soiled.
Patent DE-3801931-A1 (DE)
Title: Method and circuit for operating a shearer loader hauled by roadway winches
Inventor: WEBER KARL-HEINZ DIPL ING
IPC: H02P5/50
Filed: 1988-01-23
Abstract: Shearer loaders which are hauled back and forth over the face length by means of a hauling member of roadway winches move at a non-uniform feed rate on account of the change in the extension of the hauling member caused by the constantly changing travel resistance. Not only the cutting tools of the cutting drums but also the drive motor and reduction gearing of the two winches as well as of the shearer loader are therefore subjected constantly to shock-like loads. The novel method is intended to compensate for these fluctuations in the travelling speed of the shearer loader. It is proposed to determine the acceleration of the travelling movement of the shearer loader (1) exceeding a limit value and to utilise an electric signal corresponding to the acceleration for regulating the speed of the drive motor (10) of the respectively hauling roadway winch (9) and of the drive motor (4) of the cutting drums (3) of the shearer loader (1) in order to reduce the acceleration of the travelling movement of the shearer loader (1). <IMAGE>

Title: Paraglider formed from flexible material
Inventor: GLOECKL HANS
IPC: B64D17/02
Filed: 1988-02-24
Abstract: A paraglider (1) which is formed from flexible material, has upper and lower sails and ram-air chambers, also called cells, which are formed between these sails and are open to the incident flow. In regions which are important to shape stabilisation, for example along the front upper air inlet edge (5), along the central ram-air chamber between the cell wall and the upper sail (6), and along the lower edge of the side stabilisers (7), the paraglider is provided with inflatable, flexible mouldings. These flexible mouldings are inserted into cavities formed by the parachute material, can be replaced when necessary and can normally be inflated before takeoff. When the hoses are empty, the parachute can be compressed into its normal packing volume. <IMAGE>
Patent DE-3809748-A1 (DE)
Title: Toggle connection for the add-on parts of conveyor troughs
Inventor: NOECKER GUENTER
IPC: B65G19/28
Filed: 1988-03-23
Abstract: Chain scraper conveyors are used in underground mining and tunnelling for conveying away the material to be conveyed, above all in the coal face and roadway region. These conveyor troughs, which are composed of individual trough lengths, are connected to one another in the connection region in each case via coupling bolts having centring heads at the trough lengths and via toggle joints at the add-on parts, in such a manner that a reliable transmission of the tensile forces is also ensured in the case of horizontally and vertically angled-off trough sections. In this arrangement, the toggles cover the coupling bolts, the toggles themselves being protected by a securing plate which covers the introduction and bearing channel of the toggle receptacle and prevents the toggle from falling out of the toggle receptacle and also prevents the penetration of dirt. It is also possible for holding pieces to be used instead of the securing plate. Long service lives and an advantageously convenient assembly with corresponding preassembly above ground are ensured in the case of corresponding construction of the toggle connection. <IMAGE>
Patent DE-3810178-A1 (DE)
Title: Broadcast receiver, particularly vehicle receiver
Inventor: MARDUS CLAUS
IPC: H04H40/18
Filed: 1988-03-25
Abstract: In vehicle receivers having a decoder for decoding traffic messages received digitally coded, storage devices are provided which contain route-specific features. An especially large amount of storage capacity is taken up by place names since, for example, 65,536 place names must be stored for the region of the Federal Republic of Germany. Since these place names appear several times, for example in the case of common routing or intersections and triangular junctions, the storage requirement can rise drastically if all place names are stored with each routing name. According to the invention, it is proposed to store place names in each case only once under the route-specific features and to combine other route-specific features only with the single storage location for this place name even in the case of a multiple allocation to one of the place names. <IMAGE>
Patent DE-3811001-A1 (DE)
Title: Apparatus for spraying mortar in a sheet-like manner
IPC: E04F21/02
Filed: 1988-03-31
Abstract: For spraying cement-based mortar in a sheet-like manner, use is made of a platform (2) on which devices (6) for treating the mortar are arranged and which bears an extension arm (3) on which a spray head (11) is held such that it can be displaced longitudinally in a reciprocating manner. The platform (2) is configured such that it can be fitted on a vehicle, e.g. the fork of a forklift truck. The spray head (11) is held adjustably on a linkage (10). Lines (12) for the mortar which is to be sprayed lead to the spray head. By means of this apparatus, it is possible not only to give a uniform mortar coating to horizontal surfaces on a planar backing, but also to give a uniform mortar coating to surfaces which are inclined up to the vertical, and even to spray overhead, movement of the platform causing a movement in one direction of a right-angled coordinate system and displacement of the carriage (9) causing a movement of the spray head in the other direction of the coordinate system.
Patent DE-3816841-A1 (DE)
Inventor: KIELGAS HANS DIPL ING
IPC: B60M1/18
Filed: 1988-05-18
Abstract: In electrical tracks with overhead wire operation, the traction line is divided up into individual traction line sections by section insulators. So that they can be passed over, the section insulators are provided with contact skids. If there is different electrical potential between two traction line sections, the current collector discharges a power arc which destroys the section insulator. Attempts have been made to extinguish the arc by bypassing via a switch. The drive coil of the switch is connected between an auxiliary electrode which extends into the second traction line section and is insulated with respect to it, and the second traction line section, so that the arc current flows through the drive coil. This arc current fluctuates in such a way that actuation of the switch is not ensured so that damage nevertheless occurs. The intention is now to ensure that the switch switches reliably and namely with a specific delay (e.g. 80 ms) and opens with a considerably longer fall-delay time of e.g. 200 ms. According to the invention, the drive coil of the switch is connected to the auxiliary electrode and the second traction line section directly via a saturation converter, the secondary voltage of which, connected to the drive coil, is constant and independent of the level of the arc current flowing in the primary winding. A rectifier for rectifying the output alternating voltage can be connected to the secondary winding of the saturation current converter and the drive coil of the switch can be constructed as a direct current drive coil.   Section insulators are used for the electrical isolation of a first and of a second section of an electrical traction line for traction vehicles having an insulating body which electrically isolates the sections. <IMAGE>
