Patent DE-2758377-A1 (DE)
Title: Scissors with double finger grips - for simultaneous use by two people are for teaching physically or mentally handicapped pupils
Inventor: EICHINGER HARTMUT
IPC: B26B13/20
Filed: 1977-12-28
Abstract: Scissors have two pairs of finger holes (a), (b). The pupil places his fingers in the inner holes (a) and the teacher places his hand over the pupil's hand with the teacher's fingers in the outer holes (b). The pupil's hand is thus continuously guided whilst he is learning to use an instrument which might cause injury if misused. In an alternative design, the two finger holes for each blade lie on a line parallel to the longitudinal direction of the blade.

Title: Shift register unit with similar stages - has detector finding number of free storage locations, so that corresponding number of shifting signals can be applied
Inventor: BAUER FRANZ-LOTHAR ING GRAD
IPC: G11C19/28
Filed: 1978-06-29
Abstract: The shift register unit (SA) has a number of similar shift registers corresponding tothat of data words to be read into the unit (SA). The number of storage locations in each register corresponds tothat of data words in a series of data words. A detector (DE) delivers a signal for each data word and for the beginning and end of a series of data words. Switches (Z, D, SP), controlled by the detector signals find the number of unoccupied storage locations in each register, and deliver corresponding control signals. They are applied to a clock pulse generator (T1) for delivery of a number of shifting signals which can still be applied to the shift register unit (SA).

Title: Roller bearing for linear motion - has planar oval track for continuous row of rollers joined together by pair of flexible plastics chain belts
Inventor: HEUPEL GEB KRAUSE MARIE-LUISE
IPC: F16C33/46
Filed: 1978-09-06
Abstract: The bearing includes a carrier (1) with a straight, flat track (2) on both its upper and lower surfaces; and an end cap forming a semicircular track is located at each end of the bearing. A continuous, flat oval path is thus provided for a row of bearing rollers which are joined together by a pair of flexible plastic belts functioning like chains. The track (2) on one side of carrier (1) has a depth less than the dia. of the rollers, thus forming a thrust surface (4) on the carrier. Both end surfaces of each bearing roller posses a blind axial hole entered by a peg (19); and each plastic belt carries a row of pegs (19) forming a chain link with the rollers. Each plastic belt pref. has its max. width where the pegs (19) are fixed, but the width tapers to a thin section to form a "hinge" between adjacent rollers. Bearing is used to guide and support slides on machine tools, or to support heavy machine parts travelling or reciprocating along a linear path.
Patent DE-2838916-A1 (DE)
Title: Surface decoration for ceramic plates, esp. split tiles - where programmed sand or shot blasting produces different patterns on each tile
Inventor: LOEHR WILLI
IPC: B24C1/04
Filed: 1978-09-07
Abstract: A row of plates or tiles is pushed stepwise through a chamber fitted with nozzles via which streams of sand or other materials are used for the sand- or shot- blasting of the surfaces of the tiles; and the direction and/or intensity of the streams is varied according to a program so patterns are produced on the surfaces of the tiles. In an embodiment, the tiles stand vertically on edge on a conveyor, so they travel through a chamber fitted on both side walls with horizontal and vertical rows of blasting nozzles; and a template is located on each side of the tiles so the streams of sand must pass through the two templates. By adjusting the direction and/or the intensity of the sand streams, a different pattern can be obtd. on each tile.

Title: Oil slick barrier - carried folded up by tanker or platform and released in emergency
Inventor: KUEPPER FRANZ-JOSEF
IPC: E02B15/06
Filed: 1979-06-07
Abstract: Floating oil slock from a wrecked tanker or a leaking offshore drilling/prodn. platform is kept within local boundaries by an oil barrier which encloses the oil leak source at a certain distance. The oil barrier is stored in a folded-up condition in a separate container around the tanker hull or platform; it consists of an apron with a floating tubular collar at one end and compressed air bottles for automatic inflation at the other end which also act as ballast weights. In case of emergency, this complete barrier is jettisoned at once by the opening of a single continuous release flap. This takes up no space inside the tanker and is able to localise the possible oil leak from the largest tankers even in heavy seas.

Title: Individual seeds positioning on conical radial bores in wheel - using suction below bores, whilst removing excess seeds by suction above bores
Inventor: BECKER REINHARD
IPC: A01C7/04
Filed: 1980-02-04
Abstract: The mechanism arranges granular material, such as seeds (13), individually at the circumference of a rotating wheel (1) (or moving belt), e.g. prior to sowing. The wheel has outwardly diverging radial bores (4) in its periphery whose narrow diameter is less than that of the smallest seed (13). The wheel is enclosed in a housing (2) with supply hopper (7,5) for the seeds. A tube (8) extends from a level above the bores and back into the hopper (5).

Title: Folding deformed coated wood particle board - involves edge pressure application, and cemented v=groove
Inventor: MOELLER ACHIM DIPL ING DR
IPC: B65H45/12
Filed: 1980-08-22
Abstract: Surfaces produced by U-shaped grooves are cemented, in folding deformed structural elements comprising thin panels of pref. wood-particle materials coated with flexible foil, or similar. The groove (4), varying its direction inside the panel (1), is worked into the panel by a tool (3) moving in an arc shape, or by correspondingly moved tool and panel, so that, with the groove cemented, its adjacent surface areas produce an overall three dimensionally formed fold-structure element. The edges of the panel are engaged by pressure units, and at the beginning of folding others engage in the area of the panel surface. Inexpensive panels can be given all-round rigidity, and a good finish with interesting profiling.
