Patent DE-3328257-A1 (DE)
Title: Pressure-medium working cylinder
Inventor: ARNOLD DIETER
IPC: F15B15/14
Filed: 1983-08-04
Abstract: In pressure-medium working cylinders with a bushing and cylinder end parts closing its ends, at least one catch groove on the outer circumferential surface of each bushing end area, a skirt which forms a sleeve-like extension of each cylinder end part, is made in one piece with the cylinder end part, encloses the bushing and is locked to it in the catch grooves against axial relative movement, and also connections for the operating medium in the cylinder end parts, and seals between the ends of the bushing and the cylinder end parts, there is the problem of designing these pressure-medium working cylinders in such a way that they are not only easy to assemble but are also easy to dismantle in a non-destructive manner and of effectively distributing the forces acting on them during operation. To solve this problem, special locking elements (1) are utilised to lock the skirt (2) to the bushing (6), which locking elements (1) are held in recesses (11) of the skirt (2) and, with ribs (12), engage in the catch grooves (13) provided in the bushing end. The special locking elements (1) are conveniently designed as cylinder segments and are held in engagement by a clamping ring surrounding them. The bushing, the cylinder end parts and the locking elements can be made of glass-fibre-reinforced thermoplastic. <IMAGE>

Title: Carburettor for an internal combustion engine
Inventor: SCHMELZER GUENTER
IPC: F02M37/20
Filed: 1983-09-23
Abstract: In order to prevent hot starting and hot drive-away problems due to vaporising of fuel, a fuel reservoir chamber (9) is connected to the outlet side of the float chamber (6), from which former chamber fuel is fed to the intake pipe and the fuel volume of which chamber is considerably smaller than that of the float chamber (6). In connections (10, 11) between these two chambers (6, 9) solenoid valves (12, 13) are inserted, which only open during operation of the internal combustion engine, so that when the engine is shut down the intake pipe is connected only to the relatively small volume of fuel in the reservoir chamber (9) and consequently therefore only small amounts of fuel vapour can pass into the intake pipe. Immediately after starting of the engine, on the other hand, the quantity of fuel contained in the float chamber (6) and the reservoir chamber (9) is immediately available to the engine. <IMAGE>

Title: Clamping device
Inventor: STUEWE DETLEF
IPC: F16D1/091
Filed: 1984-01-20
Abstract: Pressure rings having external conical surfaces and clamping rings having corresponding internal conical surfaces are used for fixing component hubs on shafts. These parts can be braced with respect to one another with the aid of clamping screws, and the component hubs can hence be fixed on the shaft. Furthermore, it is known for pressure rings and clamping rings to be displaced hydraulically relative to one another and to be braced radially with respect to one another. However, special sealing elements are necessary for this purpose. The invention now provides hydraulic bracing which manages with simple O-rings 9, 17 as sealing elements. For this purpose, additional conical surfaces 15, 16, pointing in the same direction, are provided on a radial flange 10 of the pressure ring 3 and on an auxiliary clamping ring 12, in addition to the conical surfaces 8, 4 of the clamping ring 7 and pressure ring 3. Within the elastic deformation limits, the cone angle of these conical surfaces 15, 16 correspond to the cone angle of the conical surfaces 8, 4 of the clamping ring 7 and pressure ring 3. <IMAGE>

Title: Triangle for squaring the circle and doubling the cube
Inventor: SCHUETZENMEISTER OTTO
IPC: B43L13/00
Filed: 1984-12-14
Abstract: So far, there has been no possibility in the elementary geometry of a circle to solve the so-called squaring of the circle, i.e. to determine graphically with satisfactory accuracy the square with the same area as a given circular area and vice versa, and the same applies to doubling or halving the cube in a way that can be carried out graphically. With the aid of the triangle for squaring the circle and doubling the cube, which represents a right-angled triangle made from transparent material having the smaller angle  alpha  = 32 DEG  12' 33'' (tg alpha  APPROX 2"3/2> this can be achieved in a simple way with high measurement accuracy and without the use of additional drawing instruments and a calculation that has been necessary to date. If the diameter 2 of the circle is given, the lower radius of the circle is to be halved, and a perpendicular is to be raised at the point 3 of bisection. The next step is to apply the squaring triangle 1 with its apex 5 at the point 10 of intersection of the circle 7 in a manner coincident with the cathetus 6, the point 8 of intersection determining up to the point 10 of intersection the required side 9 of the square of equal area. <IMAGE>

IPC: G01N25/48
Filed: 1985-05-14
Abstract: For the purpose of dynamic output differential calorimetry, a single oven (10) is first used to subject the reference sample only to a temperature program which is supplied by a programmer (12). In the process, the values of the heat output supply to the reference sample are stored as a function of the temperature measured at the oven (10) by a temperature sensor (16). Then the sample is exposed in the same oven (10) used for generating the temperature program to the heat outputs which are stored with respect to the individual temperatures. The actual temperatures of the sample are measured by the temperature sensor (16). The sample is supplied with an additional compensating heat output which, in accordance with the difference between the stored, programmed temperature and the actual temperature, changes so as to correct said temperature. This additional compensating heat output is output to a plotter (42) or computer. <IMAGE>
