Title: Negative resist prodn. using vinyl]-phenol] vinyl-silane copolymer - developed by aq. alkali, giving high resolution and reactive ionic etching resistance
Inventor: SEZI RECAI DIPL CHEM DR
IPC: G03F7/075
Filed: 1987-03-11
Abstract: Resist structures based on negative resists contg. Si are produced using actinic radiation, opt. in the presence of photoreactive components (I), by using a vinylphenol-vinyl silane copolymer of structure (II) as resist material: m+n=1 and n= ma.0.55; X=H or halogen (i.e. F, Cl, Br or I); R1=H, halogen alkyl (i.e. Me or Et) or haloalkyl; R2=H, Me, Et, Pr or Ph; the X, R1 and R2 gps. can be the same or different. USE/ADVANTAGE - The resist can be developed with aq. alkali, is not swollen by the developer, gives high resolution and is resistant to reactive ionic etching in oxygen plasma. It is esp. useful as top resist in the 2-coat technique, which is much simpler and hence cheaper than the image reversal process. Vertical sides can be obtd., allowing wide line width tolerances, and structurisation can be carried out in the deep UV region, which is important for sub-micron technology. It is also possible to use dark field masks to reduce scattered light.

Title: Valve actuating arrangement for internal combustion engines with a plurality of valves of the same type for each cylinder
Inventor: SEIDL JIRI
IPC: F01L1/18
Filed: 1987-03-17
Abstract: In a valve actuating arrangement for internal combustion engines with a plurality of valves of the same type for each cylinder a cross member is provided for the common actuation of all valves of the same type. The cross member has a number of separate sliding pieces corresponding to the number of valves, which pieces on the one hand directly interact with a respective control cam and on the other hand interact directly with the valves by way of a hydraulic clearance adjusting element arranged in the cross member. Due to this direct valve operating mechanism the cross member may advantageously be designed as part of a fork lever formed from a light alloy material.

Title: Method and apparatus for determining water content in liquids based on oil and in similar liquids
Inventor: HORTTONEN KALEVI
IPC: G01N21/31
Filed: 1987-04-15
Abstract: The invention relates to a method for determining water content in liquids based on oil and in similar liquids, in which, without need for a reference liquid and as an essentially continuous operation, the flowing liquid to be analysed is passed through and the light absorption of the liquid serves as a measure of the water content in the liquid. To be able to continuously and automatically determine the water content in these liquids, it is characteristic of the method that the light beams are passed through at least two filter/detector pairs (7, 9 and 8, 10), of which filters the one (7) transmits only one wavelength in a region in which the absorption by water is great and the other (8) transmits only one wavelength in a region in which there is essentially no absorption by water, and are introduced into an apparatus (2) which, on the basis of the relative difference in the light intensities of the beams (11, 12) coming from the filter/detector pairs, determines the water content in the liquid to be analysed. <IMAGE>

Title: Tearable individual package for a sanitary article
IPC: B65D75/12
Filed: 1987-06-24
Abstract: In tearable individual packages, an upper and a lower pouch are formed by folding over a one-piece laminated film, the edge parts of which pouches are welded (inner inner seams). The upper pouch overlaps the lower one and is likewise welded in the edge part of the overlapping region (inner outer seams). The holding forces of the inner inner seams have to be greater than those of the inner outer seams or those of an adhesive strip sealing the upper pouch. The weakening of the seams has previously been achieved by surface treatment, such as corona discharging treatment or printer's black coating. The object consists in designing a package having an untreated laminated film to be more easily tearable along the centre bonding line and the inner outer seams than the inner inner seams. The object is achieved by a dual-layer laminated film which has, as the outer layer, a thin layer film made of a material such as polyethylene and, as the inner layer, a peelable film. Intermediate treatment is not required. Packagings for articles used for sanitary purposes. <IMAGE>

Filed: 1987-07-04
Abstract: The actuator is developed in such a way that, if desired, the two pistons (7, 8) automatically return to a certain centre position and remain in this position by shifting a control valve (21). For this purpose, a valve (10 to 18) depending on the piston position is installed in each of the cylinders (7, 8). The valve (10 to 18) blocks a pressure line (20) and a pressureless outlet line (23) in the centre position of the piston, connects the pressure line (20) to the cylinder (6) and blocks the outlet line (23) between the centre position and the retracted end position, and connects the outlet line (23) to the cylinder (5) and blocks the pressure line (20) between the centre position and the extended position. The said valves are designed as slide valves with a fixed control piston (10) and a control bore (9) in the piston (7). <IMAGE>

Title: Water meter with inlet rotor
Inventor: WAWRETSCHKA GUENTER
IPC: G01F1/10
Filed: 1987-08-31
Abstract: The water meter with is provided with a (star-shaped) inlet rotor (3), sitting on the rapidly running shaft of the counter mechanism, for the photoelectric sampling of the rotational movement of the inlet rotor from without. The inlet rotor (3) is designed as a transparent light-conducting body, which carries on its upper side a central light entry section (13) for the transmitter and a plurality of external light exit sections (14) for the receiver of the photoelectric sampler (17). By means of first, central, sloping deflection faces (15) arranged on the underside of the inlet rotor (3) and interacting with the light exit sections (14) and of second, external, sloping deflection faces (16), a 2 . 90@ deflection of the light from the light entry section (13) to the light exit sections (14) is produced. Above the inlet rotor (3), a stationary cover plate (21) is provided, which has a central opening (22) for light entry and, in the region of the light exit sections (14), a plurality of corresponding light conducting slits (23) for light exit with light-covering tongues (24) lying between them. By means of this light deflection at the inlet rotor (3), much more light is available for the pulse generation than previously. A pronounced light-dark effect occurs as a result of the upper cover plate (21). <IMAGE>

Patent DE-3739440-A1 (DE)
Inventor: BREED DAVID S
IPC: G01P15/00
Filed: 1987-11-20
Abstract: The indicator indicates if an airbag inflator for a vehicle was set off in an accident. In one embodiment, the indicator records the movement of a ball 30 in an enclosed tube 20. The record is made when the tube 20 is collapsed around the ball 30 in response to pressure or heat from the activated primer. If the ball is trapped in a position along the tube, then airbag inflation was caused in response to excessive deceleration which caused the ball to move along the tube. However, if it is trapped in its rest position, then airbag inflation was initiated in error. Alternatively, a pressure response device or a temperature sensor, placed in the primer chamber, is used in combination with an accelerometer and circuitry is provided to respond to signals from those devices to indicate whether deceleration or initiation of primer occurred first. <IMAGE>

Title: Circuit arrangement for the hydraulic corner cylinder of a shield-type support assembly
Inventor: WEIRICH WALTER
IPC: E21D23/26
Filed: 1988-02-10
Abstract: The invention relates to a circuit arrangement for the hydraulic corner cylinder of a shield-type support assembly of known type. The corner cylinder (1), which can be specifically retracted or extended by means of a hydraulic control device (4), is hydraulically locked by means of a stop valve (13) which is constructed as a double-release non-return valve. The arrangement is made in such a way that the stop valve (13) is closed in the set state of the shield-type support assembly and thus the hydraulic corner cylinder (1) is hydraulically locked. During the setting phase, however, the stop valve (13) is open so that the pressure space (5) of the corner cylinder (1) is connected to a pressure-relief valve (11) which is set to an opening pressure of, for example, 60 to 100 bar in such a way that the corner cylinder (1) can be bridged during the setting phase. Furthermore, the invention is directed towards a double-release nonreturn valve. <IMAGE>
