Patent DE-3738765-A1 (DE)
Title: Letter-box arrangement
Inventor: KUHN FRANK
IPC: A47G29/12
Filed: 1987-11-14
Abstract: The letter-box arrangement comprises a box-shaped housing (11) having an end wall (19) running around like a frame. A single letter box or a letter-box block (12) consisting of a number of individual letter boxes is inserted into the housing (11). Fitted in between the housing (11) and the letter-box block (12) parallel to the top (17) is an eaves moulding (25) and, parallel to the bottom (14) and the two side walls, a trim frame of the same thickness. The trim frame and the eaves moulding are sections of the same profile body. This profile body comprises a base body with an approximately rectangular outline. Closed smooth wall surfaces are present on the two narrow sides. The eaves moulding (25) adjoins the one narrow side of the base body with the eaves edge as a profile part. In the region of the top, the profile-body section is inserted with outwardly projecting eaves moulding (25), whereas in the remaining sections the eaves moulding (25) reaches into the inside of the housing (11) and the smooth wall surfaces are directed outwards and form the trim frame. <IMAGE>

Title: Actuator
Inventor: WOLF FRANZ JOSEF
IPC: F16J3/06
Filed: 1987-12-10
Abstract: The actuator with a rolling diaphragm clamped between a lid and a pressure-chamber part is characterised in that the rolling diaphragm is designed as a trough which is open at the top, is completely stress-free, is in the installation condition and in the installation position and in the side wall of which there is constructed an annular shoulder which runs in the form of a conical funnel sloping axially and radially inwards and merges via gently rounded-off transition contours into the diaphragm wall portions. The axially and radially inner one of these two transition contours is used as a preformed rolling fold in the already relaxed diaphragm.

IPC: F01P3/22
Filed: 1988-03-19
Abstract: In order to adjust the respective cooling temperature to the optimum temperature for the operating mode of the internal combustion engine (1) at any given time, a coolant mixture comprising water and an antifreeze possessing an essentially higher boiling temperature is used; due to evaporation of the water in the cooling chambers of the internal combustion engine (1) the antifreeze there is concentrated, thereby increasing the cooling temperature which, by purposely introducing coolant from the condenser (7) through corresponding actuation of a coolant pump (10), is adjusted to the respective operating mode of the internal combustion engine (1). <IMAGE>

Patent DE-3828033-A1 (DE)
Inventor: BOHMHOLDT GERD DR
IPC: C07C263/04
Filed: 1988-08-18
Abstract: In the preparation of diisocyanates from diamines, urea and alcohols with thermal cracking of the biscarbamate formed, it has hitherto been impossible to utilise the by-products formed in the cracking stage, and thus to arrive at a technically practicable and economical process. It was therefore the object of the invention to search for an appropriate way which avoids the said disadvantages. 
<??>The object was achieved when a cyclic process for the preparation of (cyclo)aliphatic diisocyanates was found wherein, starting from diamines, by-products from the thermal cracking, urea and alcohol, the biscarbamate is produced in the presence of N-unsubstituted carbamates and dialkyl carbonates and with removal of NH3, the subsequent cracking of the biscarbamate is carried out in the liquid phase without solvent, the diisocyanate and alcohol are condensed, the diisocyanate is subjected to a final distillation and a part of the reaction mixture from the cracking with the by-products formed is purged and, after first being reacted with raw alcohol arising, is recycled to the biscarbamate preparation stage.

Title: Control valve
Inventor: PHILLIPS EDWIN D
IPC: F16K41/10
Filed: 1988-09-29
Abstract: The invention relates to a control valve with a bellows seal for valve parts, connecting sections of conduits and the like, the bellows seal having an elongate bellows folded in the form of an accordion with a first and a second end and a multiplicity of reinforcing rings arranged at an axial distance apart. The bellows is produced from a solid blank in the form of an elongate thin-walled tube, on the outer surface of which the reinforcing rings are arranged and which is then compressed axially to give it the accordion-like configuration. According to an exemplary embodiment, the bellows extends coaxially around an actuating part of a valve so as to seal off the actuating part relative to the valve body. Threaded sections on the opposite ends of the bellows along corresponding sections of the actuating part engage in one another in such a way that a backwards and forwards motion of a regulating element is achieved when the actuating part is rotated. The direction of the threaded sections can differ in order to double the rate of displacement of the regulating element for a given rotation of the actuating part. In another exemplary embodiment, the actuating part can be provided with a pressurised piston instead of threaded sections to move the actuating part and the regulating element carried by the latter. <IMAGE>

Title: Fuel injection nozzle for internal combustion engines
Inventor: AUWAERTER GERHARD
IPC: F02B3/06
Filed: 1988-12-08
Abstract: In injection nozzles of the generic type the object is to design and arrange the control slide valve (50) so that the valve needle (28) temporarily moves into the closed position between pilot injection and main injection. To achieve the object, it is proposed to arrange the control slide valve (50) parallel with the valve needle (28) in the nozzle body (10) and to provide fixed wall breaches (70, 80) in the nozzle holder (10) between the control opening cross-sections (72, 82) in the control slide valve (50) and the control passages (74-78) in the valve needle (78) or the pressure chamber (40). Diesel engines with direct fuel injection are the preferred sphere of application. <IMAGE>
Patent DE-3901065-A1 (DE)
Inventor: VEMMER REINER DIPL ING
IPC: B66F7/00
Filed: 1989-01-16
Abstract: Said device includes, on a moving base frame (1), two lifting frames (5/6) carrying a platform (4) for receiving the bogie to be changed; the height of these two lifting frames can be separately adjusted by lifting units (2/3). One of the lifting frames (6) can be linked with the platform (4), so as to move together with it, via pillars (7) mounted on said frame, which are movable between an operational position and an inactivated position, thus ensuring the lifting movement over the other lifting frame (5). The base frame (1) includes a vertically and horizontally movable device (10) for dismantling and mounting track crossmembers which receives a track crossmember (8) in the area of the bogie to be changed for mounting and dismantling from the elevated rails. The lifting gear formed by the two tie-bar-like lifting frames (5, 6) and the platform (4) is of small outer dimensions and, in the retracted (lowered) position, has a reduced structural height and, since the lifting movement is effected in two stages, it achieves a relatively large lifting height despite its reduced height. Pantograph-type systems (14) ensure that the platform extends is a stable manner, without reaching its overturning moment, when it is being raised so that the load can be taken up even from an off-centre position.

Title: Method for the determination of thermal conductivity
Inventor: MEYER GERHARD DR ING
IPC: G01N25/18
Filed: 1989-01-19
Abstract: Method for the determination of thermal conductivity, in which the Peltier or Seebeck effect is used. In the first mode of operation, a thermal flow is generated in the material to be examined by means of the electronic changeover switch (2) and the constant current source (5), via the Peltier element (1). By means of the control (6) and the changeover switch (2), the thermal conductivity meter is switched over. In this second mode of operation, the voltage, which is proportional to the differential temperature, is produced by means of the Seebeck effect on the Peltier element (1) and represents a measure of the thermal conductivity, is picked up by a sample-and-hold amplifier (3) and converted into values capable of further processing by means of the analog-digital converter (4). The method for the determination of the thermal conductivity is distinguished by the ability to be easily realised. A statement about the thermal conductivity is possible in a short space of time, since almost no transient behaviour is to be recorded. Since the same system is used both for the generation and for the measurement of the differential temperature, quasi-point-like measurements can also be undertaken. <IMAGE>
