Title: Securing means for prefabricated saddleback-roof parts
Inventor: FABRITZ GERHARD
IPC: E04B7/24
Filed: 1988-04-21
Abstract: The invention relates to a securing means for prefabricated saddleback-roof parts which are connected to one another in an articulated manner at the ridge and comprise panels, between which rigid foam is introduced. The object of the invention is to provide a securing means for such prefabricated saddleback-roof parts which can itself be used as a prefabricated part and permits simple roof mounting which is tension-free and/or compression-free for the load-bearing walls of a building. In particular, the intention is to use prefabricated saddleback-roof parts of this type for retrofitting buildings with flat roofs which have become non-leaktight. In accordance with the exemplary embodiment shown in the drawing, the securing means comprises two identical, mutually opposite U-rails 1 with downwardly directed legs which are bent off at right angles. Tie rods 2 are guided through bores introduced in the legs, as a result of which the U-rails are connected to one another. Furthermore, identical gusset plates 3 with slopes which correspond to the roof form which is to be constructed, preferably at the same spacings from one another, are attached in a vertically upright manner on the horizontal, upwardly pointing base surfaces of the U-rails. Supporting bearings 4 for receiving the roof are fixedly positioned on the gusset plates 3. Furthermore, threads are provided at the ends of the tie rods 2 such that the U-rails 1 can be screw-connected at a predetermined spacing by means of nuts 5. The supporting bearings have the same length as the U-rails and comprise ... Original abstract incomplete. <IMAGE>

Title: Roof structure with integrated venting
Inventor: PEGLAU FERDINAND DIPL ING
IPC: E04D13/17
Filed: 1988-06-13
Abstract: A roof structure (1), which is suitable in particular for a lightweight flat roof for industrial buildings, is composed of a room-side covering (3), of a sheeting (7) which is arranged above this and is intended as a vapour barrier, of an insulating layer (9) and of an exterior covering. The exterior covering is made up of a plurality of covering webs (11) which form a joint region at their borders (13). In the joint region (15), the covering webs and the covering (3) are permeable with respect to hot gases, with the result that rising hot air can escape into the open in the event of a fire. Consequently, the stability of the building in the event of a fire is increased. A supporting element (23) between the borders (13) of the covering webs (11) bears the latter and keeps them at a defined spacing and, if appropriate, bears a covering moulding (15) in addition. <IMAGE>

Title: Fuel injection nozzle for internal combustion engines
Inventor: KOMAROFF IWAN
IPC: F02B3/06
Filed: 1988-06-16
Abstract: The object of the invention is to design injection nozzles with outwardly opening valve needle (18) so that the entry of fuel into the combustion chamber is distributed and phased in such a way that the power, the noise behaviour and the consumption and emission values of the engine are improved. The object is achieved by a valve sleeve (34), displaceably supported on the valve needle (18) and pressed against its closing head (20) by its own spring element (70), which valve sleeve is provided on the outer circumference with at least one longitudinal groove (76) for passage of the pre-injection fuel, which is closed by covering over at the end of the pre-injection lift. The arrangement is preferably designed so that a main injection duct leading by way of the valve sleeve (34) is opened only after closure of the longitudinal groove (76), so that pre-injection and main injection phase are separated from one another by a brief interruption of the injection. Injection nozzles for diesel engines with compression ignition are the preferred sphere of application (Fig. 1). <IMAGE>

Title: Circuit arrangement for producing pulses having a high edge gradient
Inventor: FROEHLICH WALTER DIPL ING
IPC: H03K17/0416
Filed: 1988-06-23
Abstract: It is known for pulses to be produced using push-pull circuits which contain two series-connected transistors of opposite conductance type. The emitters of the two transistors are connected to one another and this connection point forms the output of the circuit. Using the circuit according to the invention, it is intended to produce pulses with a high edge gradient and a low power loss. To this end, the collector circuits of two transistors (T1, T2) are connected. At least one of the two transistors is driven via a differentiating element (C1, R1, R2; C2, R3, R4) whose time constant is less than the pulse duration. The invention is used for producing drive pulses for the high-voltage (high-tension) cascades of television replay units, and for the cathode of video camera tubes. <IMAGE>

Patent DE-3826944-A1 (DE)
Title: Laterally sealed bearing bush
Inventor: GLOECKNER HERMAN
IPC: F16C29/06
Filed: 1988-08-09
Abstract: A laterally sealed bearing bush (1) which partially surrounds a shaft (2) and has a full-length longitudinal slot (4) has, in its bore, at least one groove recess (10) extending in the circumferential direction, in which a snap ring (12) is inserted loosely with radial play.

Title: Method and device for the controlled lubrication of pairs of friction locations
Inventor: SCHARNWEBER FRANZ DIPL ING
IPC: F16C33/66
Filed: 1988-11-17
Abstract: The invention can be employed wherever optimum operating conditions must be obtained as regards the lubrication of friction locations, especially in the case of spindles running at high speeds, where if, for example, lubrication were excessive, power loss would occur. According to the invention, this is achieved by virtue of the fact that micro oil-mist droplets can only settle on the points requiring lubrication. The remaining points or surfaces are electrically insulated, by oil-resistant coating layers for example. Any excess oil mist is taken up and returned by condensing and flinging discs. The air flow and the high-voltage field for the ionisation of the micro oil-mist droplets can furthermore be controlled as a function of loading, giving a self-regulating lubrication circuit. <IMAGE>
