Patent DE-2454183-A1 (DE)
Title: Crystal film epitaxy on amorphous or polycrystalline substrate - by imprinting periodic structure on substrate before crystal growth
Inventor: GOETZBERGER ADOLF DR RER NAT
IPC: C30B19/12
Filed: 1974-11-15
Abstract: In a crystal growth process for the epitaxy of a film of a crystal system on an amorphous or polycrystalline substrate, a periodic plane structure with the symmetry of the system to be crystallised is imprinted on the substrate before crystallisation. This periodic structure pref. has a lattice constant which is an integral multiple of the system to be crystallised. It can be produced by scanning with an electron beam; by ion implantation, using a crystal with a channel structure as mask; by ion implantation, using a crystal with a layered structure, pref. with rotation of the mask through a given angle to give a line lattice; or by interference of electromagnetic or electron radiation. The process can be used in the prodn. of semiconductor elements. The process ensures that the film is monocrystalline and is suitable for growth from soln., from the gas phase or for vacuum vapour epitaxy. It avoids the need to use very costly substrate crystals, e.g. sapphire or spinel. The process could also be used for the mass prodn. of cheap solar cells.

Title: Slide projector with fade in facility - having two optic paths with variable transmission each with slide carrier
Inventor: POSSO PATRICK
IPC: G03B23/18
Filed: 1975-02-18
Abstract: The slide projector has a single lamp whose light output is split by a first mirror into two optic paths, each with a slide carrier. The light paths are combined by a second mirror before being focussed onto the screen using a condenser lens. The mirrors have identical patterns of reflecting and transmitting strips and coupled to a central control. They can be rotated about the optic axes so that the interaction of the two mirrors controls relative amounts of light passing down each optic path, from zero to full intensity. In this way successive slides can be faded into others using a single manual control.

Title: Links-links warp knitter - uses double headed slide needles to give visible sinker stitches on both fabric sides
Inventor: MUELLER WILLY
IPC: D04B25/00
Filed: 1976-09-08
Abstract: Doubled headed slide needles are used in a links-links warp knitter, which are mounted loosely and individually between the leading and trailing sinker guide bars. The double headed slide needles move through the slides of the leading slide bar between the guide sinkers of the leading sinker guide bar towards the rear between the guide sinkers of the trailing sinker guide bar. Vice versa, the slides of the trailing slide bar move the double headed slide needles between the guide sinkers of the trailing sinker guide bar forwards between the guide sinkers of the leading sinker guide bar. The mechanism allows the trailing needle head to form a row of stitches with the rear warps with the next row being executed by the leading needle head forming stitches with the forward warps. This ensures that the legs of the stitches are not visible in the middle of the fabric and that the sinker stitches lie visibly forwards and backwards on both sides of the material.

Title: Non-inflated emergency inner tube for pneumatic tyres - has superposed wall sections and thickened folds
Inventor: WITTNEBEN HERMANN DIPL ING
IPC: B60C17/01
Filed: 1976-12-30
Abstract: Emergency inner tube for vehicle wheels fitted with pneumatic tyres has, when in non-inflated state, superposed wall sections with intermediate folds near which the wall of the tube is thickened. The emergency inner tube supports the tyre when the latter has become damaged or defective, at those points in contact with a road surface. In normal driving use the emergency inner tube lies inside the tyre cavity nearest the wheel rim. It may be inflated but not yet under pressure. When it is not yet inflated and also when being installed, there is the risk that the folds are damaged by too-sharp bending or flexing. The thickening of the folds eliminates this risk.
