Patent DE-4204374-A1 (DE)
Inventor: KNOCHE ALFONS
IPC: E04D13/16
Filed: 1992-02-14
Abstract: In the case of saddle roofs, the roof covering of which is underpinned by an insulation, venting and ventilation of the interspace between roofing tiles and insulation is required. If profiled roofing tiles are used, there are problems in conjunction with the ridge ventilation elements which engage over the ridge and are seated, by means of their edge parts, on the roofing tiles adjoining the ridge. The invention proposes the use of special tiles, provided with a web at the front, as ridge-adjoining roofing tiles, which, in the laid state, form a bearing layer, which extends over the length of the ridge and is intended for the edge regions of a sealing strip which engages over the ridge and is, on the one hand, permeable to air and, on the other hand, water-repellent, over which ridge tiles engage and which are seated, by means of their longitudinal edges, on the ridge-adjoining roofing tiles such that they jut out beyond the sealing strip. As a result, a ventilation system is proposed which is easy to install and has improved venting and thus ventilation. <IMAGE>

Title: Control system for rotary printing machine drive motor - includes memories for coarse and fine positioning signals computed and compared with output of shaft-angle encoder.
Inventor: KRAMER UDO
IPC: G05B19/416
Filed: 1992-05-09

Title: Airbag inflation appts. for car - has cylinder of gas-generating material surrounded by filter layers held on with spiral wire
Inventor: FAIGLE ERNST M
IPC: B60R21/26
Filed: 1992-06-22
Abstract: At the heart of an airbag safety device for cars is a cylinder of material which produces gas when ignited. This occurs when a deceleration sensor is activated. The gas escapes through several filter layers wrapped around the cylinder and retained on it by a helical wire. The cylinder and its igniter are in a reaction canister in the dashboard. This canister also contains the folded up airbag. When the gas is generated, it passes into the airbag and starts its inflation. The gas movement causes areas of low pressure around the inner circumference of the reaction canister and thin foil type flaps open, allowing the ingress of ambient air. This ari cools the gas down and also means that only a small amount of gas need be generated. ADVANTAGE - Simple structure needs no separate filter housing for gas.

Title: Optical speed measurement arrangement - generates pattern of interference strips using interference beams generated by stimulated Brillouin effect
Inventor: BERNARD WALTER DIPL PHYS DR
IPC: G01P5/26
Filed: 1992-10-01
Abstract: The speed measuring arrangement contains a device which generates a pattern of interference strips at a measurement location using two crossing, interfering light beams and a frequency displacement mechanism. The frequencies of stray light passing through the interference pattern are detected as a measure of the components of the speeds of the stray light sources perpendicular to the direction of the interference strips. The frequency displacement arrangement contains a resonator  into which light from two pump light sources is coupled. The pump light is produced by the stimulated Brillouin effect between two light waves. The frequencies of the pump light are stabilized at different resonance positions in the resonator, and both light waves produced by the stimulated Brillouin effect are coupled out to form the two interfering light beams. USE/ADVANTAGE - For measuring speeds of objects, particles or liquids at defined points in space; detecting still objects, determining direction of movement. determining object surface roughness profile. Compact arrangement.

Title: Process for incinerating refuse, toxic substances and wastes in a hermetic tank
Inventor: BOHN JONATHAN
IPC: F23G5/00
Filed: 1993-08-21
Abstract: The process which is presented makes it possible to incinerate refuse and other wastes in an odourless and smokeless manner. The incineration is carried out in a hermetically sealed preheated tank with a continuous supply of heated compressed air. The material to be incinerated is supplied in compressed form and self-ignites in the tank. This leads to a chain reaction in the tank which reduces, or renders unnecessary, a further supply of energy. For the self-ignition and the incineration of materials having low calorific values, e.g. sludge, they can be mixed with hard coal or other combustible substances and then burnt.

The cleaning device (4) has in the cleaning liquid pipe (42) a cleaning liquid quantity transmitter (44) for ascertaining the quantity of cleaning liquid fed to the drinks tapping system. The output signals of this quantity transmitter are evaluated in the control device and compared with a desired quantity to permit control and termination of the cleaning process. Operation of the outlet tap in operating mode for the first time causes a time function element to be set in the control device, which time function element... a blocking signal after expiry of a predetermined operating time...
