Title: Sealing in hydraulic presses
Inventor: CLAASEN KARL HERMANN DIPL ING
IPC: B30B15/00
Filed: 1986-09-30
Abstract: The invention relates to the sealing of the cavity, subject to operating pressure, between the piston and cylinder of a piston/cylinder unit, particularly one for hydraulic presses or the like, in which the operation of the piston/cylinder unit is maintained when the axes of the piston and the cylinder are inclined and/or offset relative to one another. In order to avoid the disadvantages of complex construction and limited application and to provide a simple and universal seal for the cavity between the piston and the cylinder which allows inclination and/or offsetting of the axes of the piston and the cylinder caused by the press drive without impairing the functioning of the piston/cylinder unit, it is proposed that at least one seal (8) should be arranged on the inner surface (16), the surface facing the piston (2), of a cylindrical ring (7) with mutually parallel covering surfaces (22) perpendicular to the axis, the ring (7) surrounding the piston (2) and being radially displaceable in a corresponding recess (9) (annular groove) in the cylinder bore, the radial extent of which recess is at least twice as great as the maximum radial offset of the axes of the piston (2) and the cylinder (3), and the ring (7) being sealed off relative to the recess (9) and that the inside diameter of the ring (7, 7') should be enlarged continuously from the central area accommodating the seal (8) towards the covering surfaces (22). <IMAGE>

Patent DE-3704605-A1 (DE)
Title: Continuous soap production
Inventor: EERTINK JAN HENDRIK
IPC: C11D13/04
Filed: 1987-02-13
Abstract: A continuous process for soap production is provided by direct saponification of oil or fat in a dynamic mixer of the rotor/stator type with an alkaline saponifying agent and recirculation of the saponified mixture. The dynamic mixer additionally has a pump function which brings about the flow-through and the recirculation, which makes an external pump unnecessary. If the glycerol produced in the saponification is left in the mixture, and if free fatty acids are added to the oil or fat which is to be saponified, it is easy to produce transparent soaps.

Patent DE-3713438-A1 (DE)
Title: Heel
Inventor: VOGELSANG JOERG
IPC: A43B21/36
Filed: 1987-04-22
Abstract: It is known to stabilise plastic heels 2 by means of steel support sleeves. Such support sleeves have previously been cylindrical internally and externally. The support sleeves also serve for driving in heel-piece pins 4, with the aid of which covering heel pieces 5 made of leather or plastic are fixed on the free end of the heel 2. To increase the stability of the heel 2 at every height, the support sleeve 3 is now designed conically externally and cylindrically internally. In this manner, the cross-section of the support sleeve 3 can to a great extent be adapted to the cross-section of the heel 2 at every height. <IMAGE>

Patent DE-3715820-A1 (DE)
Inventor: SCHROEDER PETER DIPL ING
IPC: B64F1/32
Filed: 1987-05-12
Abstract: A lifting vehicle (2) for loading containers into aircraft has a pantograph-type linkage (36) mounted on a series-produced lorry chassis (4), by means of which linkage a case (8) or a loading platform can be raised. Arranged at the rear region of the case (8) or of the loading platform is an auxiliary driver's stand (18) which is occupied when manoeuvring the vehicle (2) up to an aeroplane (40) and by means of which the lifting vehicle (2) can be remote-controlled. By this means, the substantial advantage results that the lifting vehicle (2) can be controlled extremely precisely in the manner of a vehicle with rear axle steering and is at the same time very manoeuvrable. The loading and unloading of the aeroplane or of the case (8) or loading platform occurs exclusively by means of a loading gate (10) arranged at the rear end. Measures for converting the series-produced chassis (4) in the region of a driver's cabin (6) are thus avoided completely. <IMAGE>

Patent DE-3728868-A1 (DE)
Title: Small electric motor
Inventor: ALBRECHT KLAUS
IPC: H02K41/03
Filed: 1987-08-29
Abstract: The invention relates to a stepping motor which has a further excitation system in addition to the excitation system for rotating the rotor step by step. By the indirect or direct action of the magnetic field produced by the second excitation system on the rotor, which is supported such that it can be displaced relative to the stator in the axial direction, it becomes possible to carry out a movement at right angles to the rotational movement, in addition to said step by step rotational movement. The two excitation systems can be controlled independently of one another, so that the step by step rotational movement can be carried out in any axial position of the rotor, and an axial displacement of the rotor can also be carried out during the rotational movement or when the rotor is stationary.

Title: Vibration-isolated, vacuum-tight flange connection which can move to all sides to a limited extent and is intended for hollow bodies, and use of the same
Inventor: GREGORIUS KLAUS DIPL PHYS
IPC: H01L31/024
Filed: 1987-11-18
Abstract: The intention is to provide a flange connection, in particular for pipes, connection stubs or housings, by virtue of which the use of metal bellows is rendered superfluous and which can be produced and mounted in a simpler and less expensive manner. The two coupling ends (1 and 2), which are to be connected and are located opposite one another at a distance (a1), and/or a coupling sleeve (4), overlapping the two coupling ends (1, 2), are provided, within the two overlapping regions, with at least one encircling groove (1.2, 2.2) in each case, encircling grooves which are arranged on the coupling ends (1, 2) being directed towards the coupling sleeve (4), and encircling grooves which are arranged on the coupling sleeve (4) being directed towards the coupling ends (1, 2). Inserted into the encircling grooves (1.2, 2.2) is in each case at least one elastically deformable sealing ring (3a, 3b) in the form of a round cord ring or O-ring of such a ring thickness that, in the state in which it has not yet been compressed, it projects beyond the groove depth with a considerable part of its cross-sectional diameter (DR). In the mounted state, then, the following relationship applies: <IMAGE> where DKE is the diameter of the encircling ring seat surfaces (5) of the coupling ends (1, 2), DKH is the diameter of the encircling ring seat surfaces (6) of the coupling sleeve (4), and k is a dimensionless flattening factor, where, furthermore, k < 1.

Patent DE-3739311-A1 (DE)
Title: Wooden rotor blade for model aircraft
Inventor: HAEHNLE VOLKER
IPC: A63H27/133
Filed: 1987-11-20
Abstract: The manufacture of rotor blades for model aircraft is exacerbated in that, in order to ensure that the static centre of gravity line is in the vicinity of the leading edge of the rotor blade, a groove must be milled out there, a lead strip inserted and fastened, and the groove must then be closed again. In order to avoid this work, and at the same time to displace the rotor blade centre of gravity towards its tip, it is proposed according to the invention at least partially to replace the rotor blade leading edge material by a weight-increasing material whose relative density is considerably higher than that of the normal leading edge material. <IMAGE>
Patent DE-3742635-A1 (DE)
Title: Stroke-controlled wiper system for motor vehicles
Inventor: LEBERSHAUSEN KLAUS DR ING
IPC: B60S1/36
Filed: 1987-12-16
Abstract: In the case of known wiper systems with a stroke-controlled rotary motion the forward motion and return motion of the wiper take place on the same paths of motion. A higher wiping frequency can, as a result, only be achieved by increasing the driving power. This leads to higher load moments and to higher stresses on the mechanical parts. The intention with the novel wiper system is to obtain a higher wiping frequency without also increasing the driving power. A non-uniformly transmitting gear mechanism causes different paths of motion for the forward motion and return motion of the wiper. In particular, the forward motion can take place on a stroke-controlled wiping path and the return motion on a central wiping path.
