Patent DE-2423360-A1 (DE)
Title: Ornamental sheets esp in aluminium - thin edge is bent to form angled profile with wider shank forming front face
Inventor: BOETTCHER SIEGFRIED
IPC: B21D53/00
Filed: 1974-05-14
Abstract: Ornamental sheet, especially in aluminium for television and radio sets or record players, where one thin edge is bent to form an angled profile, where wide shank forms the front face of the sheet. To form a sharp corner edge (14), a directly adjacent edge strip (15) of the outer face (16) of the thin shank (11) is thinner than the broad shank (12). Moreover, both shanks are flat. Specifically a triangular section, straight groove is produced in a piece of sheet and on grinding the bend edge (19) the opposite side face (23) of the groove (21) is also ground.

Title: Arrgmt. for flexible connection of pipelines - uses flexible diaphragms to connect flanges mounted on the pipe ends
Inventor: TUECKMANTEL HANS-JOACHIM DIPL
IPC: F16L59/21
Filed: 1974-05-18
Abstract: The flexible connection consists of two pipe ends which can slide over one another with clearance. Each pipe end is provided with a flange. Flexible metal diaphragms in the shape of single convolutions are welded with one end to the flanges on the pipe ends and with the other ends to inside diameters of flanged rings which are positioned round the flanges on the pipe ends. The two flexible convolutions point toward one another. A third flexible diaphragm in the form of a sleeve is welded to the outside diameter of the flanged rings. The space between the diaphragm can be filled with insulating material.
Patent DE-2430876-A1 (DE)
Title: Detachable hose connection - has elastic end formed into bead
IPC: F16L37/04
Filed: 1974-06-27
Abstract: The connection is particularly for use in medicinal techniques, the elastic hose end (3) being formed into a bead (4). The bead can be of circular cross-section, joining tangentially onto the hose end. The design causes the reinforced hose end to grip the spout etc. over which it is fitted elastically, so that the contact area can be kept small and detachment is thus easy even when the two have been assembled together for some time, as the bead needs merely to be rolled off the spout.
Patent DE-2433845-A1 (DE)
Title: Self-loading agricultural vehicle - has intermediate conveyor with axis forward of loading drum delivering to intermediate chamber
Inventor: KRONE BERNARD JUN
IPC: A01D89/00
Filed: 1974-07-15
Abstract: The material is loaded by a drum rotating on a horizontal transverse axis, together with a rotary intermediate conveyor parallel to it. The latter encloses with the drum and the times on it on one side and with a guide wall extending from the drum on the other side a first transport passage for the crop. Knives extend from the wall, working with tines on the drum. A further elevator with tines works in a second passage connected to the first and delivers the material into the vehicle body. The axis of the intermediate conveyor (16) is in front of the loading drum axis (6) in the travel direction, and the first transport passage curves (12) round the intermediate sack-shaped settlement chamber (45) forming the lower end of the second passage (25). This chamber is above the intermediate conveyor ad in front of its axis in the travel direction.

Title: Support frame for wall mounted fittings - is made from hollow adjustable profiles and filled with concrete
Inventor: TRIEB PETER
IPC: E03C1/328
Filed: 1974-10-23
Abstract: The support frame is used for fastening of wall mounted objects such as draining boards and lavatory basins on walls made from lightweight material. The frame is made from steel profiles and it is sufficiently stiff to prevent spring effects or bending under load. The support frame can be made from hollow rectangular cross section profiles and it has a base profile provided with vertical and longitudinal slots for fastening on the floor. The slots enable to make adjustments in positioning. The vertical member is pushed telescopically into the vertical arm of the base frame and the vertical part is held by locking screws. A sliding bracket with a projecting arm is able to slide on the upper vertical member. After completion the hollow profiles are filled with concrete.

Title: Drilling rig underwater structure - for use at great depths, can be assembled from pre-fabricated elements
Inventor: KNABE STEFAN
IPC: E02D29/09
Filed: 1974-12-07
Abstract: In the production of an underwater structure, particularly foundations for a drilling, transport or working platform for use in very deep water by successively sinking a series of interconnectable elements, a tubular body is sunk in a vertical position and disc-type base elements with a central opening are successively brought over the tubular body and are lowered to the region of the lower end of the body or to the support provided by the previously lowered base element. An underwater structure can be produced from a relatively small number of pre-fabricated elements and can be taken out to sea either to its final site or to the pre-erection site via channels of 12-20 m depth at most.
Patent DE-2502996-A1 (DE)
Title: Remote selection system using audio frequencies - has receiver consisting of filters and amplifier without resonant circuit
Inventor: DIRR JOSEF ING GRAD
IPC: H04Q1/45
Filed: 1975-01-25
Abstract: The remote selection system uses AF signals for selection codes and has its high-ohmic AF receiver constructed from one or more amplifiers and selective filters. One frequency is used to mark the beginning and end of the code, and two frequencies are used for marking signals, with corresponding high pass and low pass filters. For the one marker frequency the signal has a given tolerance for the number of periods and a given number of periods are added as a prefix to each character. The amplifier is connected to the voice line without a resonant circuit and the selective filters are coupled before or after it.
Patent DE-2515677-A1 (DE)
Title: Towbar for simplified trailer coupling - has folding, self locking joints to suit trailer/tractor spacing
Inventor: CASPERS LUDWIG DR ING
IPC: B60D1/40
Filed: 1975-04-10
Abstract: The tow-bar for the trailer is jointed in at least two places, with the hinges (5) operating in vertical axes, in opposing directions for adjacent sites. This allows the two bar to be folded double to shorten the distance between the trailer and the towing vehicle. The towing vehicle is backed onto the trailer to less than the extended towbar and the bar is unfolded to the spacing and connected. As the tractor is pulled forward the bar straightens and is automatically locked in the straight setting by automatic bolts (18) on each hinge. This allows a one man operation for the coupling without any special care required to position the tractor.
Patent DE-2520058-A1 (DE)
Title: Remanence state stabilisation for ferroelectric component - use electric AC field applied to polarised component in remanent state
IPC: H01G7/06
Filed: 1975-05-06
Abstract: The remanent condition of a ferroelectric component, with a coercive field strength and remanence values of the hysteresis loop, defining the polarisation which is affected by a polarising electric field, is produced by application of an alternating electric field to the polarised component in its remanent condition. Thus the remanence value is reduced by one to several percent. Preferably the alternating electric field has a frequency within the sonic range, typically 10 to 100 Hz. The alternating electric field may have an amplitude within the range of 0.3 to 0.7 times of the coercive field strength, preferably 0.5 times.

Title: Stabilised steerable trailer tow bar - with reaction brake to block steering on retardation by clamp tightened around steering pivot
Inventor: STRUBE WILHELM
IPC: B62D13/02
Filed: 1975-07-29
Abstract: The trailer is fitted with a steerable front axle (1) linked to the towbar (4). The towbar is provided with a telescopic section (6) which is compressed by the reaction force on braking. A leverl (8b) pivotted between the towbar and the axle steering pivot (2) swings under the reaction force and operates a brake band around the steering pivot. This locks the steering of the trailer during braking, as well as during severe retardation. This prevents the trailer from snaking, especially on downhill runs and during emergency braking. The brake band is in halves, adjustable relative to the pivot so that the band is just off the brake surface when unstressed.
