Patent DE-3638347-A1 (DE)
Title: Control surface system for controlling aircraft
Inventor: HEINRICH ANDREAS
IPC: B64C5/10
Filed: 1986-11-10
Abstract: The control surfaces (3) and (4) are provided with a control surface incidence angle  alpha R corresponding to any control surface rotation angle  eta  (see Figure 1) by deflecting the control surface rotation shaft (2) through the angle  beta  with respect to the aircraft X-axis. In the case of a control surface rotation angle of eta  = 0@, the control surface incidence angle  alpha R3 consists of the sum of the wing incidence angle  alpha F and of the incidence angle of the control surface (3) with respect to the wing (1). As the control surface rotation angle  eta  becomes greater, the control surface incidence angle  alpha R3 is reduced by the amount  DELTA alpha 3 = tan  beta  x sin  eta , the incidence angle  alpha R4 of the control surface (4) at the same time increasing by a specific amount of  DELTA  alpha 4. The sum of the vertical components of the control surface loads Rz of the control surfaces (3) and (4) accordingly run from a maximum in the -Z direction at  eta  = 0@ to a maximum in the +Z direction at  eta  = 90@. In this "nose-up" flying attitude ( eta  = 90@ and maximum wing incidence angle  alpha Fmax or pull-out where n > 1), turning flight can also be initiated by control surface deflection, with an aileron effect. In this case, the control surface system on one side of the wing is rotated from  eta = 90@ to  eta  = 0@. The maximum vertical control surface load Rz is in this case rotated from +Rz to -Rz. The lift asymmetry on the wing produces the required moment Mx. At the same time, when  eta  = 0@, in comparison with  eta  = 90@, the high induced drag on the control surface (4) - because of the reduction in the incidence angle  alpha R4 - reduces, so that the total drag W of the control surface system at  eta  = ...

Title: Bearing body
Inventor: KASSNER KLAUS
IPC: B24B13/005
Filed: 1987-04-10
Abstract: A description is given of a bearing body for the surface treatment of thin, fragile shaped bodies, in particular for the grinding of spectacle lenses. The bearing body has, on its underside, recesses for the engagement of an adaptor mounting of a grinding machine and, on its upper side, a precision-manufactured support surface for the shaped body to be machined. The bearing body consists for example in its entirety, but in particular at least in the region of the support surface, of high-strength thermoplastic material with great hydrolysis resistance which can be machined in the  mu m range. This bearing body is on the one hand capable of dealing with the mechanical stresses, it is wear-resistant, pressure-resistant and insensitive to impact. As a result of the great hydrolysis resistance, the dimensional stability of the bearing body is extremely high, even when used in a moist surrounding medium, which is very important in particular in the grinding of spectacle lenses, it being possible further to increase the cost-effectiveness of the machinery of the shaped bodies.

Title: Laser-optical end element
Inventor: LINDNER FRIEDRICH DR
IPC: H01S3/034
Filed: 1987-09-03
Abstract: A laser-optical end element (15), which is inserted into an annular metal mount (18) and at the same time forms a sinter-glass solder connection, is to provide the required vacuum-tight connection with little outlay in terms of materials to be used and required processing steps. It has surprisingly be found that no particularly extensive temperature matching between the laser-conducting material of the end element (15) and the metal of the mount (18) is required if the end element (15) is formed with a cross-section cambered in the shape of a hood - according to the optical requirements with plane-parallel surfaces or with surfaces cambered in the shape of a lens in the central hood region (16) - and is radially connected to the metal mount (18) with a glass-solder sintered ring (23) being positioned in between, without the tensions which occur during cooling from the solder temperature to ambient temperature leading to inadmissible changes in the predetermined geometrical-optical properties of the end element (15). In this way, a metal which can be welded to the material for the resonator housing (11) without problems, such as in particular a conventional iron-nickel alloy, can be used for the metal mount (18). <IMAGE>

Title: Spin-stabilised bomblet cluster munition (carrier projectile) having bomblets which can be supported during ejection
Inventor: ALTENAU ERNST-WILHELM DIPL ING
IPC: F42B12/62
Filed: 1988-12-13
Abstract: In the case of spin-stabilised bomblet cluster munitions (10) which accommodate bomblets (14) (which are stacked as the payload) and have fillers (18) and drivers (19) for fixing of and transmission of spin to the bomblets, until now, the bomblets (14) have not been supported radially directly during ejection from the casing (16), so that, as a result of their centrifugal forces, the bomblets (14) can immediately kink with respect to adjacent bomblets during ejection and damage can be caused, for example to the bomblets' fuzes (48). The invention provides a remedy for this, in that the fillers (18) and drivers (19) still initially remain connected by means of a plug connection, which consists of a retaining pin (36) and a hole (38), after ejection from the bomblet cluster munition (10), and not until then are they gradually released from one another as a result of the decaying retention force and the existing radial force. In consequence, the bomblets (14) cannot kink immediately during ejection from the casing (16) of the cluster munition (10), but can initially be released from one another in the axial direction, and then increasingly in the radial direction. The plug connection is furthermore simple to produce and requires no additional space within the bomblet cluster munition (10). <IMAGE>

Title: Marking device with a printing unit
Inventor: TENZLER THOMAS
IPC: B42D5/04
Filed: 1989-02-28
Abstract: In known strip-like marking devices, one or two free ends must be folded over to the back so that a tab-like structure is produced which has to be applied to the printing unit by hand and is held there by clamping on a sheet or a bundle of sheets of the printing unit. The novel marking device is to be usable in a more cost-effective manner and to require no assembly costs if possible. A film section of electrostatically chargeable material is used, and the printing unit has a high electrical insulation resistance. The film section can also be designed as a film electret and can likewise be used in conjunction with a printing unit of a high electrical insulation resistance. In conjunction with a printing unit, the marking device can be manufactured in a simpler and more cost-effective manner because no assembly costs occur at all. <IMAGE>

Title: Pneumatically operated full-lining disc brake, in particular for heavy commercial vehicles
Inventor: KLAUE HERMANN DR ING
IPC: F16D65/54
Filed: 1989-03-30
Abstract: The invention described relates to full-lining disc brakes with direct application. In order to keep the operating volume as low as possible, the application of the brake is effected directly by the relevant brake-operating ring, only on one side. On the opposite side, the operating pressure is transmitted by mechanically acting, infinitely variable adjusting devices mounted distributed over the circumference, with clamping freewheels and play adjustment, during the releasing process. In order to ensure functional reliability of the readjusting devices, provision is made, as freewheel rolling members, for rollers which are supported, arranged on circles, on hexagon oblique faces with little Hertzian stress. As a result, perfect working of the brake and an appropriate service life are guaranteed. <IMAGE>
