IPC: G05D23/13
Filed: 1990-06-15
Abstract: To improve the mechanical loading capacity of a set point control device on a thermostatically controlled mixing valve for cold and hot water, in which the position of the thermostat element can be determined by means of a rotary member on a movement thread and the rotary member interacts with an adjustable stop ring to limit rotation, it is proposed that a fixed gripping sleeve be secured on the stop ring, essentially overlapping and encapsulating axially the movement thread and the adjusting nut, and that a cup-like gripping piece with an annular collar engage under the inner wall of the gripping sleeve, the gripping piece being connected to the adjusting nut in a manner which prevents relative rotation but allows axial displacement and can be clamped by at least one screw against a shoulder of the adjusting nut.

Title: Machine for finish machining of oval workpieces - has workpiece motion derived from gear train with simple linear and rotational movements
Inventor: OBERG HANS-JOACHIM DR
IPC: B23B5/24
Filed: 1990-06-21
Abstract: Oval sections are important in IC engine design and production. Sections of the form R=a(1-sin. sq.alpha)+b sin sq.  alpha where R is 'radius', a and b are the largest and smallest half axes, and < is the angle between R and one of the axes, can be generated by simple linear and rotational movements of the workpiece relative to the tool. This is achieved by the use of two fixed internal toothed gears (4,6) meshing with two pinions (3,9) which are held and driven by two cranks (2,8). An intermediate shaft (5) and output shaft (10) derive their motionn from two points (P1',P2') on ther circumference of the pinions (3,9). To the resulting linear motion of the output shaft and hence the workpiece (12) is added a rotational motion derived from shaft (17) and the gear pair (14,16). ADVANTAGE - Complex oval form can be generated by simple mechanical means.

Title: Display lighting esp. for cut glass objects in shop window or cabinet - uses optical fibres terminating in rear wall of display cabinet and at different angles for individual light beams
Inventor: SCHWAB KURT DR
IPC: A47F11/10
Filed: 1991-06-14
Abstract: A glass display cabinet is illuminated by light from a source via a number of optic fibres. These fibres terminate in the rear wall of the cabinet. The angles at which the light is emitted from the fibres at the terminations are different and arranged such that the net illumination is upon the display object. A lens at a fibre termination may be used to concentrate a particular light beam. Different spacings of the terminations give different illumination effects. The light is cold light so that no ventilation in the cabinet is necessary. This permits the cabinet to be airtight so that no dust can accrue. ADVANTAGE - Observer sees only illuminated object, not the light beams; no heating of the case. Individual light beams adjustable in direction and concn.

Patent DE-4131960-A1 (DE)
Title: Insulated pipe, esp. for transporting heating media underground - has inner steel pipe wrapped in glass or mineral fibre, and outer plastic jacket, with polyurethane foam in the space between
Inventor: HEINRICH FRIEDHELM
IPC: F16L59/13
Filed: 1991-09-25
Abstract: A heat-insulated pipe (I) for long-distance heating has an inner steel tube (A) for the heating medium and an outer plastic jacket (B) sepd. from (A) by spacers, with an insulating material (C) filling the space between (A) and (B). (C) consists of (C1) an annular layer of insulating material based on glass or mineral fibre (II) on the inner tube itself, and (C2) polyurethane (PU) foam which is expanded to fill the remaining space and keep layer (Cl) under compression. Layer (Cl) is bonded to the outside of tube (A). Specifically, (Cl) is bonded to (A) with an adhesive (III) which is stable to at least 250 deg C, pref. a phenolic resin adhesive. The thickness of (Cl) is such that, when the temp. in (A) is below 200 deg C, the temp. at the junction between (C1) and (C2) is below 130 (pref. below 120) deg. C.. The spacers are formed by annular layers of (II) sepd. from one another along the axis of the tube, which are compressed by straps encircling (C1) together with straps on the inside of tube (B). USE/ADVANTAGE - The method provides insulated piping for transporting a heating medium, e.g. at up to 200 deg C. The construction of (I) compensates better for the different thermal expansion of the inner tube and the outer jacket, so that the pipe can be laid at greater depths than prior-art pipes (as described, e.g. in DE-AS 2823051) with less likelihood of damage, esp. at expansion joints, due to cracking of the plastic followed by ingress of moisture.
