Patent DE-3909084-A1 (DE)
Inventor: MALLORY JOHN
IPC: G08B17/107
Filed: 1989-03-20
Abstract: A smoke detector has a housing apertured to permit introduction of smoke. A photodiode 10 projects a beam of light along a projection axis through the interior of the housing to a light-absorbing catcher 16. A multiplicity of light receptor zones are formed about the projections axis to receive light deflected from the projection axis by smoke particles. In one form, these receptor zones are the inlet ends of fiber-optic light guides LG which receive and direct the deflected light onto the active surfaces of a photodector 18 whereby producing a signal indicative of the cumulative intensity of the deflected light. In another form Fig 3 (not shown) a sheet of flexible photoresponsive material (52) is shaped into generally cylindrical structure about the projection axis and once again produces a signal indicative of the cumulative intensity of the deflected light. In either form, the light intensity signal is compared with a detection threshold, an alarm signal being generated when the threshold is exceeded. The detection threshold can consequently be raised to reduce the incidence of false alarms. <IMAGE>

Title: Domestic refuse collection box (or container) for private households, offices, practices, etc.
Inventor: SCHENKEL ALEXANDER
IPC: B65F1/00
Filed: 1989-03-25
Abstract: For the separate collection, in a manner which is both quantitatively and qualitatively more effective, of recyclable useful materials encountered, especially, in domestic refuse such as discarded glass, scrap metal, waste paper and compostable waste (and, possibly, other wastes which can be recycled or disposed of separately), with a view to optimising reuse of the wastes, the types of substance occurring are collected separately at the place of their production (household, industrial enterprise or the like) in the domestic refuse collection box consisting of four individual elements (or containers). The individual elements are each fitted with a removable lid and a supporting ring which can be lowered, and can be assembled together by means of one or more contact points or plug points integrated into all four lateral surfaces of each element (in a manner similar to the LEGO building brick principle) by variable combination, depending on the physical conditions at the respective place of use, to form, for example, a compact square or linear refuse collection box. (The elements can also be used in pairs or individually). Without its being necessary, for example, to cover long distances within the possible place of use (residence) and without the aesthetic disadvantages generally entailed by external waste collection containers of the type hitherto customary for recycling waste (plastic bags, buckets, etc.), the wastes, pre-sorted centrally at the place of origin in a convenient manner and without great effort, can be taken by individual categories to the recycling systems for the valuable materials.

Title: Thickness measurement of extremely thin polymer films - using one laser beam aimed at layer and second almost parallel to layer and measuring deflection
Inventor: GUESTEN HANS DR
IPC: G01B11/06
Filed: 1989-06-21
Abstract: In a process for measuring the thickness of extremely thin polymer layers, a beam of laser light is aimed at a thin polymer layer. A small localised area of the polymer is heated and gases immediately above the heated polymer also warm up. A change in refractive index therefore occurs. A second beam of light is passed parallel to the upper surface of the polymer and just above it. The light is deflected and a measurement of the deflection gives a figure for the thickness of the polymer layer.  A light absorbing colour material is added to the polymer so that the max. absorbtion is in the band of the laser light. USE/ADVANTAGE - For measurement of the thickness of polymer layers which are only a few nanometres thick. Such requirements are found in microelectronics and corrosion protection as well as the optical industry. The laser beam can be focussed to very small dimensions, which enables the opto-thermal effect to occur even on uneven surfaces.
