Patent DE-4122605-A1 (DE)
Inventor: ZUR STEEGE WOLF
IPC: F16K1/226
Filed: 1991-07-08
Abstract: The valve has a frame (1) which defines a passage opening (2). The latter can be closed by a flap (3). At the end of the closing movement, the edge of the flap runs up against a spring-steel strip (5) bent in the form of a U. In its interior, the latter is provided with a reinforcing device in the form of a sheet (7) matched to the U shape. The sheet holds the frame-side limb of the strip and prevents impermissible deformations of the latter, even if the edge of the flap engages in proximity to the centre of the bend of the spring-steel strip. The same applies if significant negative pressures are acting on the strip (5). <IMAGE>

Title: Sinking borehole with drill string contg. motor for rotary bit - includes equipment for data measurement and transmitting data to surface
Inventor: COMEAU LAURIER EMILE
IPC: E21B47/01
Filed: 1991-08-27
Abstract: Improved techniques are provided for drilling a deviated borehole through earth formations utilizing a rotary bit 22 powered by a drill motor 24, and for obtaining information regarding the borehole or earth formations while drilling. An accelerometer 60 is positioned below the drill motor 24 and within a sealed cavity of a housing 42 fixed to a drill motor sub, and a transmitter 62 within the sealed cavity transmits acoustic signals indicative of inclination determined by the accelerometer to a receiver 70 provided in a measurement-while-drilling tool 46. The MWD tool is provided within a non-magnetic portion of the drill string, and further houses accelerometers and magnetometers for determining borehole orientation. Both borehole inclination signals and borehole orientation signals are transmitted to the surface by the MWD tool, and the drilling trajectory may be altered in response to the signals where required. These techniques are advantageous as they provide monitoring of borehole inclination near the bit rather than at a distance of typically 20 to 100 feet from the bit as with conventional techniques. <IMAGE>

Patent DE-4205226-A1 (DE)
Title: Spinning frame for spinning brake operation - has easily accessible spindle brake which locks on for defined period
Inventor: MUELLER HEINZ DIPL ING
IPC: D01H7/22
Filed: 1992-02-20
Abstract: The brake is operated at the disc. The mechanism is supported on the plate to the spindle rail. The spindle is held in the house fixed to the rail by a nut. The belt is the tangential drive to the whorl. The mechanism may be driven by compressed air, fluid, or by electrical means. It is operated over a set time period, and then released. The disc is spring held. It presses a piston in a compressed air cylinder in a manner which presses a brake liner against the whorl. The spring returns the disc, gradually shutting off the compressed air to release the brake. USE/ADVANTAGE - To operate a spindle brake on a spinning frame by means of a control which transmits power, and which holds the control in the operating position. As an operator requires both hands to attend to the upper controls at the spinning position, a knee operated control is employed at the spindle brake. This keeps in position once depressed, for a set time, or until released.

They are also suitable for dyeing polyester fibres. The dyeing is grey-ruby to dark purple with satisfactory fastness and low toxicity. In an example a dyebath was prepd. from 0.5 g 4-amino-2-nitro-2'-methoxy -diphenylamino-6'-carboxylic acid (cpd. (I) where R3 is OMe, R7 is COOH and other substits. are H), 8 g Na2SO4.10H2O and 2 g Na2CO3 in 100 ml water at 60 deg.C. strips of textile were immersed in the dyebath, which was heated in 45 min and kept 1 h at 98 deg.C. The samples were then removed and given cold and hot rinses and a boiling wash, then rinsed and dried. The dyeing was dark brown with acetylcellulose (2.5 acetyl gps./monomer unit), red-brown with cotton and polyamide, grey-brown with polyester and polyacrylic fibres and dark magenta with wool.

Title: CMOS driver with transmission circuit for dynamic random access memories - reduces noise susceptibility of circuit by increasing voltage levels
Inventor: OH JONG HOON
IPC: G11C11/407
Filed: 1992-10-21
Abstract: The driver comprises several stages (B4) to drive the word-line of a dynamic random access memory (DRAM).
