Patent DE-2601625-A1 (DE)
Title: Quenching tempering large thin-walled tubes - in straightening rolling mill stands between cooling nozzles
Inventor: KUSAKABE TAKASHI
IPC: C21D9/08
Filed: 1976-01-17
Abstract: Thin-walled steel tubes of large diameters are quenched and tempered by passing them through a straightening rolling mill stand during their quenching down to a temperature of 400 to 600 degrees C. Both the inlet and the exit side of the mill stand is fitted with cooling nozzles. Another straightening rolling mill stand can follow to ensure the final contours. Thin-walled steel tubes with a dia. of 38 - 152 cm and a wall thickness of 6 - 38 mm can be produced with very accurate dimensions. The tubes have a higher strength and a better low-temp. toughness without the necessity of expensive alloys.

Patent DE-2625370-A1 (DE)
Inventor: KOPP WALTER
IPC: B42C3/00
Filed: 1976-06-04
Abstract: In high-speed printers, an edge-perforated paper web (PB) is guided with the aid of advance means through the printing machine. In the process, driving pins engage in the transport holes (TL) and enlarge them. In order to improve the stackability of such a paper web (PB), devices are provided past which the paper web (PB) is guided before deposition with pressing, so that the enlargements at the transport holes (TL) are pressed down. Such devices can consist of two rolls (RL1, RL2) between which the paper web (PB) runs through. <IMAGE>

Title: Force measurement cell with compression body - includes bulging compensation borings requiring no electronic linearisation for strain gauges
Inventor: NUERNBERGER WILHELM DIPL ING
IPC: G01L1/22
Filed: 1976-06-09
Abstract: A force measurement cell with a compression body (3) having reduced cross-section in the measurement zone (4) and strain gauges (5, 6) attached to the side surfaces is designed to produce a linear relation between measurement signal and load without requiring an electronic linearising circuit. To compensate for non-linearities caused by bulging of the body under load, holes (7, 8) are bored in it in the measurement zone. The borings are perpendicular to the longitudinal axis and parallel to the sides on which the gauges are mounted. The strain gauges thus measure the body compression without suffering a bending effect. Transverse extension may be measured by a further gauge (9) with associated boring (10).

Title: Gas distributor fitted under a ladle - to form a gas screen protecting molten metal from oxidn. as it flows into a mould
Inventor: HILDEBRANDT PETER DIPL ING DR
IPC: B22D11/106
Filed: 1976-12-09
Abstract: Casting plant has a gas distributor located between a ladle and a chilled mould to form a screen of inert gas round the stream of molten metal; the distributor is made of a refractory material permeable to gas. The refractory material is pref. a ceramic, esp. a clay contg. particles of a combustible substance and calcined so the particles burn despite the absence of air; or the material may be a porous concrete. The distributor may be a ring located concentrically round the molten stream; or may only partly surround the stream; in either case a laminar gas stream is obtd. The distributor may be located on the base of a bottom-pour ladle; or on the top of the chilled mould. The gas distributor is simple and therefore less expensive than existing designs.

Title: Water heating system combined with refrigerator condenser - has solenoid valve draining excess hot water to protect water heater
Inventor: HACKNER HERBERT ING GRAD
IPC: F25B29/00
Filed: 1977-01-22
Abstract: The plant for using heat generated by domestic refrigerator has a condenser situated within a hot water heating tank which is heated electrically. This heat recovery system ensures that condensation energy is diverted if temporarily no hot water is demanded or if hot water demand is very low. A hot water flow control solenoid valve (13) is actuated by a regulator (11). This regulator responds to a specified temperature to which it is set. The solenoid valve (13) is switched in relation to the temperature of the storage vessel content or the liquefaction temperature of the refrigerating circuit (5). The water tank has also electrical heating element (8). The solenoid valve ensures that excess hot water is drained away for example when heater is switched off but refrigerator continues to work.

Title: Rigid strand tension members anchoring assembly - has anchor unit of binding material closely following member and socket deformations
Inventor: FOERSTER ROLF DR
IPC: E04C5/12
Filed: 1977-02-10
Abstract: The combined anchor unit and anchor socket, is for anchoring a tension member made up from rods, strands or cables of high rigid material, such as fibre-glass-reinforced plastics, as used for spanning wide gaps of withstanding heavy loading. The rods or strands pass through the anchor unit. The anchor unit takes up force from the tension member (3) and conveys it to the encompassing, supporting anchor socket (8). A bonding member with deformative and rigidity characteristics attuned to these of the tension member, allow it to follow the latter's varying lengthways deformations and those of the socket so that close adhesion to both is maintained. The anchor unit can be made of networked reaction resin containing filler.

Title: Standardising arrangement for twin beam photometer - deflects reference beam to measuring photocell for initial arrangement and includes shutter to interrupt either beam
Inventor: KIEWEL WERNER DIPL PHYS
IPC: G01J1/16
Filed: 1977-05-14
Abstract: In a twin-beam photo-meter, a light source (1) radiates a beam of light to a beam splitter (2) at which it is divided into a measuring beam (4) and a reference beam (5). The measuring beam is reflected by a device such as a mirror (3) and passes through a cuvette (6) which contains the sample to be measured. The transmitted beam (4') impinges on a photocell (8). The reference beam (5) pases through a cuvette (7) containing the reference standard to a second beam splitter (9). The transmitted reference beam (5') impinges on a second photocell (12). The deflected reference beam passes to the first photocell (8) by way of a second mirror (10). A shutter device (11) pivots to interrupt either the beam from the measuring cell or the beam from the reference cell to permit the two photocells to be set up initially.
