Patent DE-3726433-A1 (DE)
Title: Hinge fitting for seats, in particular motor-vehicle seats with an adjustable backrest
Inventor: BERGHOF HANS-JOACHIM
IPC: B60N2/22
Filed: 1987-08-08
Abstract: The hinge parts, movable relative to one another, of a hinge fitting are connected via a spindle, there being provided an adjustment and fixing device which determines the position of the hinge parts relative to one another and is designed as a gear mechanism, the spindle having a motive element which can be moved by a driving element. A frictional braking device fixes the hinge parts in their adjusted position. A braking device of this kind can be realised, for example, by a brake spring coupling connected between a hinge part and the spindle. Apart from the overall width of the hinge fitting needing to be large for this, high demands are placed on the accuracy of manufacture since alignment errors in the bearings and tolerances in the toothings can lead to constraining forces which increase the adjusting torque. The mentioned disadvantages can be avoided by the spindle having a support ring, which fits over areas on the outside of one hinge part, whilst on the spindle portion which projects away from the other hinge part there is held a spring arrangement which compresses the hinge parts in the axial direction. This spring arrangement on the one hand causes the hinge parts to be compressed to produce a braking torque and, on the other hand, shows the tendency of the spindle constantly to try to adopt a tilt-free central position of its longitudinal axis parallel to the bearing axis. The [lacuna] acting counter to the spring force ... Original abstract incomplete.

Patent DE-3733955-A1 (DE)
Inventor: GAMBERINI ANTONIO
IPC: B65B19/32
Filed: 1987-10-08
Abstract: On a conveyor leading to a cigarette packing machine, the presence and completeness of the cigarettes (4) forming a group (3) of cigarettes are sensed by a number of pin feelers (18) equal in number to the cigarettes (4) in the group (3) and each designed to traverse axially to and from one end of a respective cigarette (4) in the group (3), between an operating position, wherein the pin (18) contacts the respective cigarette (4), and a idle position; each pin (18) being connected to a sensor (25) designed to emit control signals as a function of the position of the respective pin (18) subsequent to moving into both the operating and idle positions. The sensors 25 thus operate to stop the machine if a pin (18) fails to contract a cigarette due to absence of the cigarette, absence of filter or incomplete filling, and also to stop the machine if a pin (18) fails to return to its correct idle position. <IMAGE>

Title: Jacking apparatus for the pipe jacking method
Inventor: KRAEMER-WASSERKA THOMAS DR
IPC: E21B7/20
Filed: 1987-10-13
Abstract: The invention relates to a jacking apparatus for the pipe jacking method, with a thrust ring and hydraulic jacks, acting on the thrust ring and supported on an abutment, for the jacking of the pipe run, characterised in that the hydraulic jacks are double-piston cylinders (12, 12') which are alternately connected to a front abutment (9, 9') and rear abutment (10) in order to act sometimes as pushing means and sometimes as pulling means. By the arrangement of the double-piston cylinders (12, 12') at the side parallel to the pipe section (5') to be jacked, the jacking pit (1) can be constructed with the smallest possible cross-section. According to the invention, the hitherto necessary awkward and time-consuming shifting of the jacks or the coupling elements for the thrust ring can be dispensed with. The jacking apparatus according to the invention can be easily automated by accompanying, known measures. <IMAGE>

Title: Non-reversing mechanism for pipe advances in compressed air
Inventor: SCHERLE MAX DIPL ING
IPC: E21B7/20
Filed: 1987-12-19
Abstract: In pipe advances in compressed air and with a liquid-supported rock face, the tunnel shield and the following advance pipes are acted upon by a rearwardly directed force as a result of the air or water pressure. During the advance, this force is taken up by the advance presses. In the case of the installation of new pipes and advance presses retracted for this purpose, the rearwardly directed force must reliably be taken up in another manner in order to prevent the dangerous return movement. In the case of small shield diameters and low air or water pressures, the return movement can be prevented with auxiliary devices customary on building sites. With increasing diameter and pressures, however, auxiliary devices customary on a building site no longer suffice for this purpose. The novel apparatus makes possible, in conjunction with the novel method, reliable and economical taking-up of the rearwardly directed forces for any shield diameter and any air or water pressure and thus prevention of the return movement of the shield and the following pipes. It comprises, according to the enclosed drawing, a preferably two-part blocking ring (8), a supporting ring (9), a clamping ring (10) fixedly connected to the latter, the hydraulic supporting presses (11) and the supports (12). The rearwardly directed force is ... via an annular groove (13), the blocking ring (8), the supporting ring (9), the hydraulic supporting presses (11) and the supports (12) onto the rear wall of the pressing shaft ... by the pipe advanced last ...

Abstract: The invention relates to an electrophotographic image generation process, in which an electrostatic (latent) image is generated on an image reception element containing a base or substrate on which a photosensitive layer essentially consisting of an amorphous hydrogenated and/or halogenated silicon is arranged. The electrostatic image is developed by means of a developer, consisting of a toner and an excipient, in an oscillating electric field, which is characterized in that the photosensitive layer comprises a surface-enhancing or surface-modifying layer consisting of an amorphous hydrogenated and/or halogenated silicon containing at least one atom each from the group comprising carbon, nitrogen and oxygen, and a charge-blocking or charge-barrier layer which adjoins the substrate and consists of an amorphous hydrogenated and/or halogenated silicon containing at least one atom from the group comprising carbon, nitrogen and oxygen and is doped with an element from the group IIIA or group VA of the Periodic Table of the Elements. The toner image generated (electrophotographically) according to this process is improved inasmuch as it has a high resolution and constantly high quality. <IMAGE>

Inventor: KAYS RUEDIGER DR ING
IPC: H04N11/12
Filed: 1989-04-14
Abstract: Owing to transmission with meshing spectra, crosstalk interference occurs in colour television systems which to some extent rather adversely affect the image quality. It is known to undertake three-diemsional filtering on the transmission and reception sides of colour television systems in order to obtain the lowest possible crosstalk inteference in the form of cross-colour and cross-luminance. The new colour television system contains a coding device in which the chrominance and high-frequency luminance are sub-scanned in time. In the decoding device the high-frequency of the colour television signal of the first and second half-images (whence elimination of cross-luminance) and the demodulated, low-frequency colour difference signals (whence cross-colour elimination) are added. In the new colour television system any modulation method may be used and it is compatible with conventional receivers operating on the PAL, NTSC, or SECAM standards.

Title: Consolidating cracks in marble slabs - by resin impregnation in vacuum
Inventor: TONCELLI DARIO
IPC: C04B41/48
Filed: 1989-09-11
Abstract: Slabs of marble and similar rocks, with cracks and splits are consolidated by impregnation in a vacuum with a low-viscosity resin with several additives. The resin is finally catalysed in an oven. Pref., the slabs are first completely dewatered by heat input and their rear is plaster coated to close any through holes. The cool slab is introduced in a vacuum chamber where it is dipped into the resin. After the vacuum has been lifted, the slab is left for a few minutes before extraction and cleaning. The final catalysing operation only lasts a few minutes. ADVANTAGE - This finds a valuable replacement for 100% sound marble which is becoming increasingly scarce.
