Patent DE-2538866-A1 (DE)
Title: Mfg polygonal section packaging tube foldable flat - by winding round section tube and cutting into sections before forming corner folds
Inventor: SAUL FRANZ J
IPC: B31C11/02
Filed: 1975-03-25
Abstract: The process is for the manufacture of sleeves of straight polygonal section, particularly for use as a packing item and folding flat. A round tube is first formed by winding several thin layers of glued paper, plastic etc. on a fixed mandrel. The tube is then distorted into the polygonal shape, and during this operation and while it is still wet from the glue a continuous fold is pressed into it along each edge in the lengthwise direction. After the tube has been wound to its final wall thickness it is divided into separate sections. These are then fed forward separately and individually subjected at the same time to the distorting and folding operations.

Title: Multiple path cigarette store with belt conveyors - has branch portion serving two side by side reversible stores
Inventor: HINCHCLIFFE DENNIS
IPC: A24C5/35
Filed: 1975-10-17
Abstract: The cigarette storage arrangement in which the output from one or more cigarrete making machines can be stored, then subsequently discharged, using multiple belt conveyors to form a zig-zag storage path, as in 2546599 also includes a branch serving two different stores. Thus, after passing between two belt conveyors forming a feed path, the cigarettes can travel through a forked region, one branch continuing onwards to a first zig-zag path, or alternatively sideways then onwards to a second zig-zag path. Both alternative stores are reversible.

Patent DE-2606328-A1 (DE)
Title: Paper coating process - uses an applicator with a greater feed vol. with overflow to carry away bubbles
Inventor: WALLSTEN HANS IVAR
IPC: B05C5/02
Filed: 1976-02-18
Abstract: A moving web of paper is given a coating of a cladding agent dissolved or dispersed in water such as kaolin bonded with starch or a synthetic polymer, or hydrogen peroxide or PVC by moving the paper past and contacting it with an applicator, the feed of the cladding material to the applicator being so controlled that on overflowing at the edge it gives an air-free coating surface. The vol. of the feed is greater than the vol. applied to the paper so that there is an overflow at the other edge for surplus to be removed. The process reduces the vol. of liq. applied to the paper so that further drying costs are reduced, the coating being free of air so that it is evenly and consistently applied without leaving gaps caused by bubbles.

Title: Reducing radioactive decay time of phosphorus doping in silicon - produced using thermal neutrons by optimising flux density and time
Inventor: HAAS ERNST
IPC: C30B31/18
Filed: 1976-04-08
Abstract: Reducing the radioactive decay time of the activity resulting from the irradiation of Si crystals with thermal neutrons to produce homogeneous P doping by the reactions 3oSi (n, gamma)31 Si beta -31P(n, gamma) beta -32 P(sic) involves selecting the prod of the thermal neutron flux density and the irradiation time (t)for the desired P doping in the Si per unit amt. of Si so that circle with diagonal line is adjusted to its optimum value w.r.t. the min calculated 32P activity value (S), according to the mathematical formula derived for the formation of the 32p activity. The 32P activity is reduced or altered so that doping can be carried out with up to 100 times the amt. of Si. For high resistivity (e.g. 100 ohm. cm), t is small and for low resistivity (0.1-10 ohm.cm) t is large. E.g. for doping to a resistivity of 100 ohm.cm. if t =69.4 h, circle with diagonal line = 1012 cm2 s-1 and S=6.8 x 10-3 mu Ci/kg Si, whereas if t=0.694h, circle with diagonal line = 1014 cm2 s-1 and S=4.55 x 104 mu Ci/kg Si.

Title: Feeding coal powder into kiln for baking ceramics, esp. bricks - using chain conveyor to feed row of stoking plants
Inventor: WEICHS HERMANN
IPC: F27B9/36
Filed: 1978-01-13
Abstract: The powdered coal is fed from a hopper so it enters gaps on the upper track of a chain conveyor belt; the gaps are compartments formed by transverse walls fixed on the belt; and they carry the coal along a slideway until it falls into the compartments on the lower track of the belt.

Title: Sunblind case wall attachment - uses bolt in space formed by case and clamp stem grooves to produce locking effect
Inventor: ROEDELBRONN HORST
IPC: E04F10/06
Filed: 1978-05-09
Abstract: The fixture system is for the housing for an awning sunblind, open at the front and shaped to hold canvas rolls, attachable to a wall by means of rectangular-section grooves in its horizontal faces, with a clamp engaging the groove fitted for attachment to the wall. A stem piece (12) on the clamp (10) overlaps the groove (6) which is not in contact with it. In this area the clamp itself has a homologous groove (13). When fixed in position, the cross-section formed by these two grooves is filled by a bolt (14), with a form-locking effect. The bolt is shorter than the distance of the clamp from another clamp, or from a lateral protrusion on the wall. This enables the housing to be easily and reliably fitted in confined niches or similar places on a wall.
