Patent DE-2416615-A1 (DE)
Title: Corner piece for double glazed window - contact surfaces modified to simplify assembly problems
Inventor: CECH VLADISLAV
IPC: E06B3/667
Filed: 1974-04-05
Abstract: A corner piece for insertion into hollow members for double glazed windows, as in the main patent, secured in position by an adhesive composition is modified in design to simply dimensional tolerancing and assembly problems. The component is an L shaped plastics moulding, each arm of the L shape having a pair of ribs across it, facing outwards, the two arms being connected to a corner block with serrations across its face to act as a key for the adhesive. Holes in the sides of this block also act as a key. Between the ribs are curved bridge pieces with their convex surfaces facing outwards. Across the inside faces of these arms are grooves to release chips of metal formed when forcing the pieces into the hollow members and prevent them binding.

Title: Voltage transformation using saturating oscillator - has field effect transistor controlled from transformer secondary winding
Inventor: STAHLKE JUERGEN
IPC: H02M3/338
Filed: 1974-12-05
Abstract: The efficiency and accuracy of transformers is improved by using a saturating oscillator and a FET in place of one of the two transistors normally employed. The gate of the FET (Q2) is connected through a regulating circuit (CR1, CR2, C1, R2) to the secondary winding (W3) of a transformer (T1). The bifilar wound primary (W1, W2) windings are connected thus: one to the supply terminal and one to the source-drain circuit which, in turn, controls the base of a switching transistor (Q1). A limiting resistor (R1) is included. With a voltage on the FET gate the transistor (Q1) turns off; thus reducing the secondary transformer voltage. This reduces the source-drain circuit resistance and thereby tends to turn the transistor (Q1) on and repeat the cycle.

Title: Brick layered block arrangement - has four longitudinal layers fed and one layer removed and stored
Inventor: HOEVELMEYER WERNER
IPC: B65G57/24
Filed: 1975-04-30
Abstract: The arrangement of brick layers of rectangular base face has bricks made up, for example, in four longitudinal rows and a number of transverse rows and fed by the furnace carriage. The bricks are set up in brick layers with, say, four and three longitudinal rows and equal base faces which are finally alternately stacked above each other for packaging. The brick layers with the larger number of longitudinal rows are swivelled through 90 deg. before being set down. To set up layers with three longitudinal rows from the bricks fed with four longitudinal rows, one longitudinal row is removed and stored. The removed rows are stored until a layer needs to be produced with three longitudinal rows.

Title: (semi) permanent coupling for two constructional parts - uses clamping plate and coupling bolt which passes through holes in parts and engages in plate slit
Inventor: KOCH PETER DIPL ING
IPC: F16B5/06
Filed: 1975-05-12
Abstract: The coupling for constructional parts such as angled pieces, pipes etc., comprises a clamping plate (1) with a slit having an enlarged hole (3) at one end. This plate is stepped when viewed from the side and is brought to rest against the surface of one(6) of the two parts (6, 7) which are to be joined whereby the plate hole is initially aligned with holes (8, 9) in the constructional parts. Because of the stepped plate shape, the plane of the surface (1a) in which the slit is formed creates a wedge shape with the plane of the normal surface (1b) of the clamping plate. A coupling bolt (3) with a head (4a) is passed through the parts until its shaft emerges through the plate hole. The bolt shaft has an angled groove (5) on both sides which engages with the sides of the slit when the tip (11) of the clamping plate is struck with a downward blow from a hammer. The coupling is thereby effected.

Title: Vertical belt conveyors for level orientation of letters - has inclined belt with vacuum suction and level plate
Inventor: RAPPARLIE HANS
IPC: B65H9/16
Filed: 1975-07-25
Abstract: The conveyor system is for letters has an inlet belt (4) and an outlet belt (15). The belt rollers are oriented in a vertical position. The belts run parellel with a third belt (1) which produces a reaction face for clamping the letters. It extends from the start of the inlet conveyor to the end of the outlet belt. Between the two belts (14, 15) an inclined belt (18) is located. It is provided with a vacuum suction chamber (20) which pulls the letters against the belt through holes (18'). As the letters move along, the lower edge reaches the horizontal datum plate (19). This ensures that all letters reach the exit belt at a common level which is required for the next step of the handling process.

Title: Internal focussing arrangement for field glasses - with a pair of carrier arms for the optical system
Inventor: KIRIGAYA TADAYUKI
IPC: G02B23/06
Filed: 1975-09-02
Abstract: Internal focussing arrangement for field glasses has a pair of arms which carry part of the optical system attached to the spindle so that part of the optical system is displaced axially by movement of the spindle. This is achieved by a pair of guiding rails on the lens holders which are moved parallel to the spindle jointly with the guiding rails. The spindle can be moved in the axial direction so that a projection is turned onto which a sharpness setting scale is attached and which is arranged centrally in front and between a pair of lens holders. The advantage of this system lies in simple assembly which does not require great accuracy hence production costs are low.

Title: Continuous conveyor system for oranges - has pad containing granulated particles and carrying goods along horizontal path between loaders and ejectors
Inventor: PADDOCK PAUL FRANK
IPC: B65G17/32
Filed: 1975-09-10
Abstract: The conveyor is for the transportation of sensitive goods, esp. oranges, between a supply station, where the goods are supplied free falling, to an output station. The conveyor has a continuous row of support pads. Each pad has a cover contg. displaceable granulated particles. Before arrival at the supply station, the particles in each pad are subjd. to a displacement force, so that the pad is outwardly arched. The displacement of the particles due to the force of the falling object is utilized to accommodate and reduce the active impulse forces, and to form a seat for the object during movement towards the output station. To form the outward movement, the pads are turned upside down, when they return from the output-to the supply station via the lower section of the conveyor.
