Title: Spacecraft equipment inertial platform protection - has rigid clamping that may be separated when in orbit to resume gimbal operation
Inventor: RAPP DIETER
IPC: B64G1/24
Filed: 1973-10-13
Abstract: In order to protect the gimbal mounted components of an inertial platform from the high 'g' forces during lift-off a technique is used to rigidly constrain the platform relative to a fixed base. Vertical strips of rigid material have a lip at the top edge that locates in a groove in the platform similarly at the bottom end of the strip a lip locates in a groove in the base plate. A wire band securely holds the strips to the platform to act as a rigid box structure. Once the spacecraft is in orbit the rigid structure can be dispensed with to allow the stabilising function. The retaining wire is of a fusable material that can be melted by applying low electrical power after which coil springs pull the rigid strips clear of the platform.

Title: Waste press with press blade swinging about an axis - has outlet with adjustable cross section
Inventor: SMOLKA KURT
IPC: B30B9/30
Filed: 1974-02-19
Abstract: The waste press consists of an inlet chamber into which a blade in the shape of a circle segment can swing. This blade presses the waste into a tapering, and slightly curved outlet section. One of the sides of the tapering outlet section can hinge about a point near the inlet so that the size of the outlet opening can be adjusted by means of an adjusting bolt. The size of the outlet opening is adjusted to keep the back pressure approximately constant for various types of waste. Side pieces are mounted in the inlet opening of the tapering section. These side pieces are placed at an angle and increase the taper of the outlet section locally. The cross section of the waste will therefore be reduced before it enters the outlet section and will not rub all the way along the sides of the outlet.

Patent DE-2445378-A1 (DE)
Title: Purification of gases - by washing or combustion with regenerative heat exchange between incoming and outgoing streams
Inventor: KRITZLER GERHARD DIPL ING
IPC: F23G7/06
Filed: 1974-09-23
Abstract: A plant for purifying gases has an inlet duct leading the incoming gas to one axial surface of a regenerative heat exchanger and an outlet duct collecting the outgoing gas from another part of the same surface of the heat exchanger. The plant incorporates means of bringing about relative motion between the surface of the heat exchanger and one or both of the ducts with means of making a gas tight joint between the surfaces. Beyond the other axial surface of the heat exchanger are the means of purifying the gas. The heat exchanger is divided into sectors by radial partitions. The sectors open to a common chamber. The gas can pass from the entry duct through the heat exchanger into the common chamber and return through the heat exchanger to the outlet duct, the purification process being carried out during its passage. Purification may be by washing with a liq. or by combustion to decompose or oxidise toxic matls. The proportion of the matl of construction which has to be in steel and to have a precisely machined surface is much less than in existing plants, because it is necessary to make a gas tight joint, between surfaces which rotate relatively, on only one of the two axial surfaces of the heat exchanger, instead of on two as in existing plants. The remainder of the structure can be in matl resistant to corrosion and high temps.

Title: Double twisting spindle with balloon limiter and improver feed - smooth limiter mantle surface, stoppages interrupt improver supply
Inventor: WAHLEN ANTONIUS
IPC: D01H13/30
Filed: 1975-02-08
Abstract: In the parent patent the balloon limiter of a double twisting spindle is provided with an outlet for an improving additive, so that each time the thread, sliding along the limiter, passes the outlet, it rubs against some of the improver liquid; the surface of the yarn on the one hand and the inside of the balloon limiter on the other, receiving a film of the additive. The additive for improving the double twisting operation, e.g. by reduing friction, or to impart characteristics necessary in subsequent processing is fed by a metering device with a nozzle directed towards the contact zone between the thread balloon and the limiter. The nozzles may be pivotted and/or axially displaced. A multispindle machine has a central control adjustable to allow a nominal feed of the additive, and thread detectors as well as spool diameter monitors control the power circuit of the metering pumps. Advantages are uniform treatment of all the threads being handled. The improving additive is not fed unnecessarily to a stationary spindle, and is fed always in a definite direction towards an accurately defined zone of the balloon limiter mantle.
