Patent DE-2653061-A1 (DE)
Title: Material conveyor for wood offcuts - has sprockets movable to allow chain kinks due to blade overloading
Inventor: VALO ANTTI TAPANI
IPC: B65G19/08
Filed: 1976-11-23
Abstract: The conveyor handles material sliding easily, eg wood off-cuts, having two sprockets (1, 2) on parallel shafts, and over which an endless chain (3) runs. Blades (4) are mounted at regular intervals on the chain. The blades are rigidly fixed to the chain, and the sprockets can move to and from each other for a distance equal to the shortening of the chain caused by blades tilting. Under overload the blades tilt to the rear, causing local kinks in the chain. The movable sprocket can be mounted in a slide, working in guides extending towards the fixed one, and spring-loaded sway from it.

Title: Photographic identification of objects by spectral signature - using transparencies of different spectral bands superimposed and viewed by transmitted light
Inventor: LOHSE KARL-HEINZ H W
IPC: G01C11/00
Filed: 1976-11-29
Abstract: A photographic method of recognising objects in a viewed area or field in accordance with their spectral signature by multi spectral photography consists of making a series of photographs in different spectral bands, esp. in black-and-white, of the same area. Those regions in the individual photographs are selected where the tone values correspond to the spectral signature of the object in the particular band. A transparent tone value extract is made photographically of each spectral band photograph, showing as transparent all the regions which have a tone value corresp. to the intensity of the spectral signature in the relevant spectral band, all the other regions being black or opaque. These transparent tone value extracts are stacked and evaluated by looking through them. This is pref. realised by stacking a marking photograph of all the super-imposed extracts.

Title: Modular duct for bus=bar insulation - has defined access points with knock=out covers which may be resealed with snap fitting shroud
Inventor: STILKERICH ALFRED
IPC: H05K7/12
Filed: 1976-12-01
Abstract: The bus duct is made up of identical preformed sections made of insulating material. The duct is of U-shaped cross-section and can accommodate one or more bus-bars. At intervals along the duct there are access points, in the form of small boxes, for terminals. The sides of the boxes protrude beyond the general outline of the duct. These protruding sides also allow interlocking the duct with at least one other identical duct in parallel. The boxes forming the access points are closed with knock-out covers. After breaking out and fitting on a terminal and its lead the area can be isolated by fitting a snap-on shroud. The form of construction requires only one insulation moulding for constructing a multi-channel bus duct of any desired length, and also permits easy access at frequent points along the run.

Title: Conveyor belt cleaning equipment - has elastomer coated rotary and reciprocating roller acting against bottom run
Inventor: OESTERLING WALTER
IPC: B65G39/073
Filed: 1977-03-16
Abstract: The equipment cleans the bottom run of a conveyer belt, and comprises a cleaning roller (18) which is coated on the periphery with elastomer material. This bears against the bottom run, and in addition to rotating on its axis is driven to and fro in the axial direction. The roller can be thrust against the belt under pressure, being rotated by friction by the latter, and the reciprocating movement can be derived from the rotary one. Pressure can be generated by a weighted (24) or spring-loaded lever (20). The roller can rotate on a fixed spindle, in which there is formed a groove inclined to the radial plane to accommodate a guide fixed to the roller.

Title: Lock clasp for safety belts - has interconnected double lever arm as actuating member for easier engagement and release
Inventor: SCHWANZ WILFRIED ING GRAD
IPC: A44B11/25
Filed: 1977-03-19
Abstract: The clasp for car safety belts includes a push-in plate and a lock casing with a manually operated spring-biased actuating device. This consists of two interconnected levers (14, 15) which can be swivelled with the bolt (11) which engages under spring tension on one of the undercut edges of the push-in plate when the latter is in the engaged position. The swivel bolt is fastened to one (14) of the levers whilst a single spring (22) which engages on the second lever (15) draws back the two levers into the starting position in which the swivel bolt is in its engaged position. When inserting the push-in plate the articulated connection between the two levers allows a relatively easy swivel movement of the first lever arm which is connected to the swivel bolt and thus only one part of the spring force of the single resetting spring need be overcome. However on opening the lock be depressing the actuating button the full resetting force of the spring is brought into effect.
