Title: Electrodeposition and etching process for patterning plates having insulating ring zones in the mouth region of bores
Inventor: TRAUSCH GUENTER DIPL ING
IPC: H05K3/00
Filed: 1982-01-26
Abstract: When photoform glass is used as a base for control levels in flat plasma image panels, the bore walls have also to be metallised. The metallisation has, however, to be interrupted at a specified point at a short distance compared with the depth of the bore. This ring insulator should, as a rule, contain the narrowest bore cross section. The main application deals with a process for enabling insulated zones to be reliably produced in the vicinity of the mouth of the bore. According to the addition, the quantity of resist introduced into the bores in the hole field and at the hole field edges is, on the one hand, kept constant and, on the other hand, the insulating ring is displaced completely into the bore and its height is kept exactly constant.

Title: Feeder for bulk materials of the type of a star wheel feeder
Inventor: OETZEL HERBERT
IPC: B65G65/48
Filed: 1983-04-12
Abstract: In a feeder for bulk materials of the type of a star wheel feeder, an internally approximately cylindrical housing with an upper inlet nozzle and a lower outlet nozzle is provided. A star wheel provided with pockets is mounted in the housing so as to be rotatable. Sealing elements extend between the pockets to the interior wall in order to separate the pockets from one another. In order to make the separation as complete as possible and to permit only a slight leakage of air from the feeder to a filter connected thereto, the star wheel is designed drum-shaped with at least one lateral surface extending to the interior wall of the housing. At least one pocket insert is inserted in the lateral surface, the opening of which insert has a smaller cross-section than the lateral surface. The lateral surface thus forms a large surface-area sealing element.

Abstract: In the invention, the patient determines his/her visual acuity himself/herself. The illuminated object is located on the rear side of the front plate. The object is imaged with a displaceable mirror on the retina via stepped dioptres. At the same time, the mirror distance is recorded in reduced form by means of a chart recorder, whereas the selected dioptre is entered via the other coordinate. After subjective detection of the optimum visual acuity a marking is placed. Fig. 1 shows a front view: the stepped dioptres are located in a vertical slide. The optical system can be used for control observation outside the device. Fig. 2 shows a side view: the deflection mirror is fastened on the fifth member of a "lazy tongs". The chart recorder is driven by the first member. The visual acuity is determined as point of intersection of two coordinates. Several devices can be placed next to one another. After use, the device can be pushed together to the size of a suitcase. <IMAGE>

Abstract: An infrared detector includes a vacuum tube containing a photo sensitive layer comprised of densely packed needles arranged vertically on a substrate and having been grown as metal whiskers in a porous portion of the substrate. The substrate includes a metallic layer either in contact with or insulated from the needles depending upon the mode of the detecting system. The needles may face the incoming radiation, or may face away therefrom, in which case at least part of the substrate has to be transparent to infrared radiation. The radiation is either acquired directly or through an infrared optic or through a raster or line-scanning system. Photo emission from the needles can be used either directly for the production of an image or indirectly through a scanning process. The diameter and distance of the needles is significantly smaller than the radiation band to be detected.

Title: Spot-type disc brake, in particular for motor vehicles
Inventor: BIEKER DIETER
IPC: F16D55/2255
Filed: 1983-05-13
Abstract: The spot-disc brake, in particular for motor vehicles, has a brake calliper (3) partially surrounding a brake disc (2) and a central application member (13) arranged on one side in the brake calliper. The brake shoe (24), which can be moved by the application member, is guided in a manner which allows it to be displaced parallel to the axis (1) of the brake disc but prevents it from being rotated about axes parallel to the said axis. The application member with its essentially cylindrical screw-type or piston construction, has a pressure part (16) through which there protrudes, in an eccentric cut-out (17), a prismatic pressure bar (19). The pressure bar extends over almost the entire width of the brake shoe, which rests against it with a rolling-contact surface (23). The line of action (32) of the force parallel to the axis (1) of the brake disc and passing through the centre (31) of friction of the brake lining (27) is offset radially inwards by a distance (a) to the point (33) of intersection of the axis (29) of the application member (13) with the friction surface (18). Near to one end, the pressure bar (19) is pivoted to the brake shoe (24) by means of a pin (35). The application member (13) is arranged at a large distance from the axis (1) of the brake disc, leaving the installation space required for other components of the vehicle free. The guidance of the pressure part (16) in a manner largely free from rotary play avoids dead travel in the application member (13). A large application stroke of the application member (13) is possible with uniform wear of the brake linings. The readjustment of the entire... Original abstract incomplete. <IMAGE>
