Patent DE-4230250-A1 (DE)
Inventor: BAETHKE KLAUS
IPC: G01L25/00
Filed: 1992-09-10
Abstract: A hydraulic cylinder for a standard force measuring machine has a rotatably mounted cylinder ring (9) which is connected for drive purposes to a rotary drive (15) and has two elastically deformable sealing rings (10, 12). The first sealing ring (10) bears sealingly against a working piston (8) projecting into the cylinder ring (9); the second sealing ring (12) bears sealingly against a guide piston (11) projecting in an opposing fashion into the cylinder ring (9). The use of elastically deformable sealing rings (10, 12) avoids a sealing gap which would lead to a change in the effective piston area and to flow forces in the axial direction. Because of the rotary motion of the cylinder ring (9), the friction forces occurring on the sealing rings (10, 12) extend only in the circumferential direction and have no effect on the axial force. <IMAGE>

Title: Delivery pump for vehicle braking system - uses throttle responsive to opening pressure of by=pass valve which can overcome pre-set evacuation negative pressure at pump outlet
Inventor: PAHL ARNOLD
IPC: B60T13/16
Filed: 1992-10-15
Abstract: Delivery pump in which a bypass valve (30, 30') made as a check valve is switched parallel to an outlet valve (18) via a throttle (29). The opening pressure of the bypass valve is smaller than that of the outlet valve and so dimensioned that it can be overcome by a pre-set evacuation negative pressure at the pump outlet (12). The throttle is tuned to the opening pressure of the bypass valve. On the delivery stroke of the pump piston (13) the resulting pressure drop is greater than the pressure difference between the opening pressures of the outlet and bypass valves. ADVANTAGE - Ensures that the closure force of the outlet valve is sufficiently large to reduce the backflow of the hydraulic medium after a working stroke.

Inventor: BUTSCHEK UWE DIPL ING
IPC: C22B1/243
Filed: 1993-03-16
Abstract: The invention pertains to a process for producing slag-forming briquettes to be used in smelting furnaces, in particular in cupolas or other shaft furnaces, wherein the briquette is made from industrially generated dusts or sands, particularly filter dusts or foundry sands, and is characterized in that the appropriate dusts or sands, particularly dusts or sands containing SiO2, are collected, mixed and moistened, that 1 to 10 % by wt. sulfite liquor or a comparable substance is added as binder and that this entire mixture is compacted under pressure in molds, which is then followed by a structural hardening phase. This yields surprisingly stable briquettes that effectively produce slag in smelting furnaces.

Title: Device for damping vibrations on the steering bar of a hand-guided, motor-driven implement, and implement with such a device for damping vibrations
Inventor: WALZ JUERGEN DIPL ING
IPC: F16F15/04
Filed: 1993-05-12
Abstract: In a known implement, the steering bar is mounted on the implement by means of two bearing spindles running transversely to one another. The bearing spindles are located in elastic bearing elements of bearing parts in such a way that the bearing spindles are arranged in a T-shape or crosswise relative to one another so that the longitudinal centre axis of the one bearing spindle essentially intersects the longitudinal centre axis of the other bearing spindle in its centre area. The known damping device is too complicated and for cost reasons can only be used in larger implements. The novel device is to be constructed more compactly than hitherto and is to be capable of being produced and fitted more cost-effectively. Only a single bearing element (3) is provided between the implement (2) and the steering bar (4). The bearing element (3) is arranged at the instantaneous centre of rotation of the implement (2) and is inclined towards the motor-supporting plate (14) of the implement (2). The device is considerably smaller than hitherto known solutions. It can save considerable costs. An implement can be dismantled to a certain extent with effortless ease and stowed or transported in a space-saving manner. <IMAGE>

Patent DE-4326124-A1 (DE)
Title: Multiphase electrical machine having subdivided, single-phase sectors
Inventor: HILL WOLFGANG
IPC: H02K7/08
Filed: 1993-08-04
Abstract: In multiphase machines having mutually overlapping phase windings, the conductor insulation must be designed for twice the phase voltage, as a result of which the proportion of insulation to the machine volume rises. In order to achieve a high power and force density, the conductor length which does not contribute to producing torque in the winding overhangs must be as small as possible. According to the invention, the conductor design of a multiphase electrical machine is divided into a plurality of single-phase, multipole sectors which are arranged such that they are offset with respect to one another by the fraction of one pole pitch. Only the current of one phase flows in each sector, which results in conductors of different phases not passing over one another and it being necessary to design the conductor insulation only for a fraction of the terminal voltage. A conductor winding runs in a meandering shape within a sector and in layers which are parallel to the air gap, as a result of which the effective conductor proportion is very high, because of the small step widths. As a result of the modular design, electrical machines are composed of a small number of structural shapes, which are prefabricated completely automatically as a result of their simple design, and in large quantities.

Title: Rotary joint for adjusting the back rest of motor vehicle seats
Inventor: HOGE RALF
IPC: B60N2/235
Filed: 1993-08-12
Abstract: In this rotary joint 1 equipped with an eccentric planetary gear for pivoting and securing the back rest, the play in the toothing and the bearing positions of the roller elements, the pinion 2 and the internally toothed gear 3 are eliminated in order to achieve quieter running and to avoid juddering. In order to obtain a simple, durable and stable solution, an outer wedge segment 4 which lies eccentrically with respect to the bearing of the internally toothed gear 3 forms the bearing of the pinion 2. It interacts with an inner wedge segment 5 which has a spring force applied to it axially by the wedge faces 6 and 7, which are at a wedge angle  alpha  which is smaller than the friction angle, of both wedge segments 4, 5 in such a way that in the state of rest the pinion 2 is forced with its toothing into that of the internally toothed gear 3 as a result of which the bearing plays of these roller elements are also eliminated. During the rotation of the pinion for the adjustment of the back rest the inner wedge segment also moves outwards which cancels the elimination of play. <IMAGE>
