Patent DE-2364927-A1 (DE)
Title: Motor-driven carpet shampoo machine with dry foam applicator - has oppositely rotating back and front rollers for forward back and stationary operation
Inventor: SCHNEIDER HELMUT
IPC: A47L11/32
Filed: 1973-12-28
Abstract: The drive device of the carpet shampoo machine comprises two horizontal floor rollers which are mounted parallel at a distance one behind the other and can be set in rotation at the same speed but in opposite directions. This allows the machine to be operated forwards and backwards and also stationary, depending on whether one or both of the rollers are engaged. A sponge roller is designed to rotate with the floor rollers and is passed along a track where it is compressed transversely to the direction of rotation so that the foam producing means which comprises a gas and fluid shampoo composition s supplied solely in the expansion region, preferably directly after the point of maximum compression and is only removed in the compression area where it is applied as a dry foam through piping to the carpet.

Title: Vehicle rear boot lid handle - creates wind turbulence effect for automatic cleaning whilst in motion
Inventor: HACK A BERT DIPL ING
IPC: B62D25/12
Filed: 1974-02-02

The handle is positioned in the upper part of the downward pointing boot lid, and has a U-shaped cross section. the flanks of the U-profile are of different length, so that air streams over the lid occuring during travel, only tangentially touch the free ends of the flanks. The same principle can be used for rear or number plate light housings or for badge insignia.
Patent DE-2405770-A1 (DE)
Title: Circular internal track for rolling ball - is entertaining to operate and beneficial to fitness
Inventor: SELTER HANS-THEO
IPC: A63B67/08
Filed: 1974-02-07
Abstract: A closed ring made from U-shaped profile forms a circular internal rolling track for a ball which is larger than the profile width. When placing the ball inside the vertical ring, moving the ring in a circular path, causes the ball to roll along its track. Above a certain ball speed, the ring track can be tilted horizontally without dropping the ball, since the centrifugal force is greater than the gravitational pull. By choosing tracks of different diameter and balls of varying weight, the required speed also changes. Moving the ball track along its required path is beneficial to fitness as well as entertaining.
Patent DE-2408445-A1 (DE)

Title: Tuber preservation system - by heat treating to turn starch into paste and adding preservatives after cooling
Inventor: STOUWDAM GERRIT
IPC: A23L19/12
Filed: 1974-09-04
Abstract: Potatoes, carrots etc. are preserved in a package after peeling or scraping by a heat treatment so that the starch present just turns pasty and the peroxydase reaction in the direction of the tuber core becomes negative up to some distance from the outside. After cooling, the tubers are preserved by a treatment with sorbic acid. Food preserved by this method remains tasty for a fortnight in a freezer and >=3 days at room temp. This durability could be achieved only by an undesirably high SO2 content of over 50ppm.

Title: Double walled ceiling or wall panels of reinforced concrete - eliminating process of turning upper wall onto lower wall
Inventor: WAGNER EDMUND DIPL ING DR
IPC: B28B23/02
Filed: 1974-10-19
Abstract: Double-walled reinforced concrete ceiling or wall panels consisting of two spaced parallel concrete walls joined by reinforcements are produced by pouring the concrete for the lower wall (5) onto a lower shuttering board with edge shuttering elements (3) lowering the reinforcements (1) from above into the fresh concrete, and casting the upper wall at a distance from the lower wall. By using the edge shuttering, which extends above the lower wall, an upwardly open space is formed in which are inserted the reinforcements and shuttering boards (2, 6) which form the lower horizontal shuttering for the upper wall. The shuttering boards rest on strips on the inner surfaces of the edge shuttering elements at a given level. The concrete for the upper wall is then poured onto the shuttering boards.

Title: High temperature tube coupling - has helical metal seal ring with inclined coils axially clamped by screw bush
Inventor: KLEINSCHMIT EINHARD DIPL ING
IPC: F16L19/00
Filed: 1975-01-10
Abstract: A metal strip of rectangular cross section is wound to a helical coil (1) to form a seal ring. The longer axis of the strip cross section forms an angle of between 30 deg. and 80 deg. with the coil axis. On installation, the seal ring (1) is placed over the outside diameter of the inner tube where it is retained by an external tube flange (9). A screw bush (10) located on the external thread of the inner tube (7) is used to axially clamp the seal ring coil on installation inside the larger tube (13). This causes the coil to increase its outside diameter whilst at the same time reduces its inside diameter. A sealed tube coupling is thus obtained.

A film firmly adhering to the substrate is formed. The film is glossy and, hence, the outlook of the sprayed object is improved.
Patent DE-2510673-A1 (DE)
Title: Continuous casting mould - shaped to prolong contact between steel strand and mould walls and increase heat transfer
Inventor: JOHNSON LYLE J
IPC: B22D11/04
Filed: 1975-03-12
Abstract: Continuous casting mould has a substantially rectangular mould passage with the major portion of the surface of two opposed walls (3,4) being convex in transverse cross section. The radius of curvature of the convex surfaces is progressively great at successively lower cross sections through the mould wall. The mould is used for the continuous casting of steel strands. The radii of curvature of the convex surface at successively lower cross sections conforms to the known or estimated shrinkage thus reducing air gaps and increasing the heat transfer from the strand through the mold. As contact between the casting surfaces and mould surfaces is contained, thus eliminating air gaps, longer mould can be used thus producing a thicker and stronger shell within the mould.
Patent DE-2511770-A1 (DE)
Title: Bellows pleated, synthetic tube enclosed in tubular net - as synthetic casings for feeder of sausage filling machine
Inventor: KOLLROSS GUENTER
IPC: A22C13/02

Patent DE-2522096-A1 (DE)
Title: Baking, roasting or reheating stored food - esp. meat held in deep frozen storage
Inventor: THOMAS THEODOR
IPC: A23L5/10
Filed: 1975-05-17
Abstract: The specific. describes a process for baking and roasting and/or reheating stored baked or roates food, e.g. for reheating previously baked food or roasted meat which has been stored deep frozen. The process uses a mixt. of steam and air as heating medium. According to the novelty, the air is maintained above atmos. press. in a state of saturation with steam/water vapour. The saturated air is passed through the oven with uniform flow distribution and minimum turbulence. The reheated food experiences no water loss and is therefore of good quality. The reheating process takes place in about two minutes, (so that no time is allowed for bacterial attack) and remains in suitable quality for several hours.

Patent DE-2536636-A1 (DE)
Title: Disc brake for motor cycle - with brake reaction link between ends of telescopic dampers
Inventor: BURY KARL-HEINZ
IPC: F16D55/228
Filed: 1975-08-16
Abstract: The disc brake assembly is mounted on one side of the wheel and is supported at the bottom of the telescopic damper mounting. This mounting presses against a special pressure element (11) which engages a thrust transfer tube (5) through whose hollow middle the axle shaft is mounted. The tube serves as the mounting for the wheel bearings, which are asymmetric, with the larger one on the side of the disc brake. The pressure element grips the tube by special claws while the telescopic damper on the other side is coupled to the tube by other claws. Braking reaction forces are thus transferred to the other damper so that the braking strain is evenly distributed to both sides of the wheel suspension.
