Title: Descaling hot rolled round stock using cross rolling unit - having work rolls with concave surface and rugose annular region to frictionally engage stock
Inventor: ABRAMSEN FINN B
IPC: B21B45/04
Filed: 1979-09-26
Abstract: Appts for forming cold finished bar from hot rolled round comprises a primary scale remover having a cross-rolling unit with a pair of work rolls each having a concave surface. A rugulose surface extends in an annular ring around each work roll on the concave surface and is used to dislodge scale from the round and to import rotary motion to the round. A pair of black up rolls have convex surface which about the concave surfaces of the work rolls. Each back up roll has a relief portion positioned opposite to the rugulose surface and is recessed so that the back up roll does not contact the mgulose surface. The combination of a cross-rolling unit as a primary scale remover and a descaling machine as a secondary scale remover provides an efficient descaling operation with increased prodn. The additn. of rolling units provides a surface finish to the bar that permits coating of the bar without further surface treatment. The absence of contact of the work roll surface with rugulose surface present wear of the rugulose surface.

Title: Storing waste heat in liquefied sodium sulphate - for delivery to user who extracts the heat
Inventor: GATTYS FRANZ JOSEF
IPC: F28D20/00
Filed: 1979-11-22
Abstract: Heat energy for solar panels, heat pumps or any waste-heat source is stored in sodium sulphate (glaubers salt) in the decahydrate form, which is dissolved in its own water of crystallisation at a temp. up to 100 deg.C. The resulting hot fluid is delivered to the user by pipe-line (for short distances) or by tanker vehicle (e.g. up to 10 km), and at the users is subjected in scaled-down appts. to the reverse process, emitting heat and returning to the crystallised condition, being then taken back to the source for re-cycling. The crystallisation process is assisted by preventing supercooling, e.g. by adding borax for nucleation. Fused silica prevents dehydration. The glauber's salt soln. stores about seven times as much heat as the corresp. amt. of pure water.

Title: Cleansing system for water treatment filter - with brief flushing treatments between longer full treatment
Inventor: KRETZSCHMAR WOLFGANG DIPL ING
IPC: B01D24/46
Filed: 1980-04-03
Abstract: A single or multilayer filter bed used for treating water is periodically flushed by water and possibly air passing through in counterflow in order to remove suspended particles, gas bubbles etc. Between the periodic treatment for completely cleaning the filter, which follow gradual clogging throughout the body of the filter, are interposed briefer flushing programmes, normally initiated by a specific drop in pressure measured at the filter surface. Cleaning of the filter surface, which is readily clogged by larger particles, means the deeper flushing of the whole filter can be postponed. The surface flushing only takes up to about 20% of the time for complete flushing. Consumption of power, water and air is correspondingly less. The flushing programme may be initiated by factors other than pressure drop, e.g. by turbidity.

Title: Mag arc welding gun using both argon and carbon di:oxide - where the proportion of argon can be reduced, thereby decreasing welding costs
Inventor: SCHMIDTKE WOLFGANG
IPC: B23K9/173
Filed: 1980-05-21
Abstract: The two gases are fed separately through the nozzle of a welding gun, the argon flowing through an annular tube surrounding a tube through which the electrode wire travels. Tube is surrounded by an outer nozzle forming a ring cavity through which CO2 flows to surround the Ar just above the welding zone. The ratio of CO2:Ar is pref. between 1:1 and 10:1, esp. using 6-7:1, or CO2 contg. 10-50% argon. The pref. gun nozzle contains two axial tubes used for the feeding of the electrode wire and the Ar. Similar conventional practice uses Ar and CO2 which are mixed together before being fed to the gun; and conventional mixts. contain up to 80% Ar, which is a very expensive gas. The invention eliminates mixing the gases outside the tube, and greatly reduces the amt. of Ar required, thus reducing cost.

Title: Stabilising device for a remotely adjustable vehicle outside rear view mirror
Inventor: HISCOX MARTYN J
IPC: B60R1/06
Filed: 1981-02-11
Abstract: The invention relates to a stabilising device for a mirror plate or mirror supporting plate of a remotely adjustable vehicle outside rear view mirror, in the case of which the plate is held in a universal joint bearing in the casing so as to be adjustable in any direction, a resiliently prestressed friction element which is movable with the plate and with respect to the casing being connected to the said plate. In known mirrors of this type, the friction element is formed by a spring clip which is inserted in expensive bearings of the plate and rests against the adjacent casing wall. It is expensive to manufacture and mount this spring clip, and the measures to which the plate must be subjected if the clip is to be mounted also involve considerable outlay. The amount of friction which can be achieved to provide stabilisation is small. Furthermore, to the extent that a plurality of friction elements are distributed around the circumference of the plate, the resilient and frictional effects of such elements must be matched to one another, as they would otherwise twist the plate about the bearing. According to the invention, the friction element is mounted on the end of a pressing rod, which is situated parallel to the plane of the plate and exhibits an inherent resilient force which is aligned in the longitudinal direction of the pressing rod, the pressing rod being longitudinally guided in at least one bearing of the plate. If this design is used, the resilient force is accurately directed towards and acts upon the contact surface between the friction element and the casing. As one friction element is advantageously mounted at each end of a pressing rod in each case and the reaction forces are balanced out by the resilient installation of the friction elements in the pressing rod itself, the plate cannot twist in an impermissible fashion by the action of the stabilising device. Vibration of the plate is, however, reliably avoided as a relatively large amount of work is consumed by friction in the contact surfaces between the friction elements and the inside surface of the casing. <IMAGE>
