Title: Sorting bags of flower seeds - uses at least two electronic readers for printed codes on bags
IPC: B07C5/34
Filed: 1973-06-29
Abstract: Closed rectangular bags e.g. of flower seeds are sorted with an electronic reader for the code on the bags, which are successively fed in the same position, e.g. resting on the narrow side. At least two readers are used in the region of a bag at different points at the sane distance from the mid-axis of the rectangle. Preferably the bags have at least 2 printed codes, at the same spacing from the mid-axis of the rectangles. The toral of codes/bag + readers = 4, divided in a 2:2 ratio, with both groups determined such that one group is on the same side of the bag at different heights, and the other on different sides of the bag at the same height. The appts. is simpler, smaller, and more trouble-free.

Title: Multi tumbler emergency opening lock - ensures key can be withdrawn when outside handle is decoupled and moves freely
Inventor: ZUENDORF KARL-ULRICH
IPC: E05B65/10
Filed: 1973-12-08

Patent DE-2365034-A1 (DE)
Title: Switching pulse generation dependent on stepping motor position - using NAND -gate receiving phase, revolution and revolution pulses
Inventor: HOHBERG GERHARD DR ING
IPC: G05B19/04
Filed: 1973-12-28
Abstract: The pulse generating system produces a pulse via a NAND-gate when the stepping motor reaches a predetermined position. For the eight-phase motor specified a coding disc with a slit marks one complete revolution of the shaft, i.e. eight steps, by allowing light to fall on a photocell. The shaft is linked over a reduction gear to a second coding arrangement, consisting of a contact and disc, which produces a pulse for every e.g. 250 revolutions of the shaft. The phase pulses from the motor control unit, the revolution pulses from the photocell, and the pulses from the contacts are all passed to the NAND-gate three inputs. When these three pulse trains coincide, the NAND-gate transmits an output pulse characteristic for the position of the motor rotor.

Patent DE-2419328-A1 (DE)
Title: Brightness control for binary stored picture reproduction - is included in store matrix scanner and has comparator
Inventor: PETER FRITZ ING GRAD
IPC: G01T1/164
Filed: 1974-04-22
Abstract: The matrix is scanned sequentially and the output of each cell is applied to a digital to analogue converter, mixed with suitable synchronizing pulses, applied to a variable gain amplifier and thence is passed to a television tube. The output of each element is also applied to a comparator to the other input of which the contents of the previous brightest element in the scan is applied, using a storage register. If the brightness exceeds this previous level, the new level replaces the old in the storage register. The brightest element in the entire scan thus becomes stored and this is used to affect the gain of the variable gain amplifier. A standard picture brightness is thus achieved. A manual brightness control is also provided.

Title: Composite waterproof watch casing - sintered powdered metal outer portion shrunk onto thin inner ring
Inventor: MEYER FERDINAND
IPC: B22F7/06
Filed: 1974-05-08
Abstract: A waterproof watch casing is made from an inner ring, inside which is located the watch movement and in which is secured the watch glass and back cover, onto which is shrunk a sintered powdered metal outer casing which has an attractive appearance. In one design, the inner ring is a brass pressing which is inserted into a mould, then spherical bronze powder is poured into the mould around the ring and compacted, and sintered in an oven under pressure to form a composite casing. In another design, stainless steel powder is compressed in a mould at room temperature, then the ring is inserted into the compressed outer member, then the two are heated together. In another method, the outer member is presintered at low temperature then finally sintered with the ring at the higher temperature.

Title: Die-halves for mfg ceramic mouldings, esp roof-tiles - using elastic sheet held on die-contour by vacuum
Inventor: LUDOWICI MICHAEL CHRISTIAN
IPC: B28B7/12
Filed: 1974-06-14
Abstract: Die-halves for the mfr. of ceramic mouldings, esp. roof tiles, use a box-shaped mould base contg. an insert, the upper surface of the insert defining the surface contour of the moulding. The upper surface of the insert is covered by a sheet of an elastic matl. which is clamped against the insert during the pressing operation. After the pressing operation, the clamping force is released, thereby lifting the moulding off the surface of the insert. The die- or mould-half is provided with devices for creating a vacuum between the elastic sheet and the insert. The device may consist of holes connected to a vacuum pipe and/or the insert may possess a porous structure, esp. of sintered metal; the vacuum can be used e.g. to retain the moulding in the die after the latter is opened and while the die travels from the pressing station to a discharge station on a rotary press-table; the vacuum is then released to eject the moulding.

Title: Butterfly valve with eccentrically mounted flap - has expansible metal sealing ring held on flap by retaining ring
IPC: F16K1/226
Filed: 1974-09-12
Abstract: The flap (1) locates in a cylindrical conduit incorporating a ring (13) on its inner wall (12), the flap bearing on this ring to effect closure and aligning in a plane parallel to the conduit axis when open. To effect sealed closure the flap bears a metal ring, of elliptical shape conforming to the conduit ring (13), locating in a groove formed by a stepping of the flap periphery and a screw (5) fixed retaining ring (4). This metal ring is of greater internal dia. (Dr) than the groove dia. (Ds) and is thus, able to deform elastically and radially during clamping of the retaining ring. The metal ring is composed of three annular discs with the outer discs projecting beyond the inner disc.

Title: Erasing on electric typewriters - has control link which requires single operation of erasing key
Inventor: FRIEDEMANN PETER ING GRAD
IPC: B41J29/26
Filed: 1974-12-21
Abstract: The erasing device is for electric typewriters or similar office machines for the correction of wrongly typed letters, which has an erasing key and an erasing ribbon in place of the colour ribbon. The device is distinguished by arranging a control link between the erasing key (17) and return switch arrangement (13) to initiate a carriage return pulse. The device can be so controlled that the carriage return arrangement (13) is only initiated by the erasing key (17) when the wrongly typed letter has not been caused by the typing of a letter without carriage movement, otherwise a locking arrangement comes into effect which is released after typing with a normal key.

Title: Movable partition wall structural components - comprising element halves with spring interconnection pressing them together when erected
Inventor: HASCHER RAINER DIPL ING
IPC: E04B2/82
Filed: 1975-04-07
Abstract: Set of structural units used for erecting movable partition walls, in eg offices connectable to each other or to a fixed wall, and with ceiling and floor attachments which can be released. Each element is in two halves superimposed sandwich-fashion, each half facing one of the two partitioned rooms when erected, and with a spring interconnection. The two halves can be moved far enough apart against the spring action, for their interval to exceed the depth of ceiling and floor attachments and lateral attachments during erection or dismantling. When the wall is erected the sprung component presses each element half with a sealing effect from outside against the various attachments, holding the entire element in place.
