Patent YU-73386-A (YU)
Title: Device for welding two mutually covered tube parts made of plastic material especially tubes with flanges
Inventor: EGGER KARL
IPC: B29C65/18
Filed: 1986-05-08
Abstract: In the method for welding two overlapping tubular plastic elements together, for example a tube (14) with a pushed-on sleeve (16), the plastic elements are heated in the area of the welding point by means of an electric heating element (1, 2) and pressed together. In order to achieve a reliable welding over the entire length of the weld without requiring consumable heating elements or the like and for a simple apparatus to be sufficient for carrying out the process, the electric heating element (1, 2) is attached to the outside of the outer tubular plastic element (16), the pressing force is applied via the heating element (1, 2) and the latter is removed again once welding has been completed. <IMAGE>

Title: Safety device for motor cars, buses, and trucks - uses manual pressure switch on steering wheel to detect fatigue or illness in driver
IPC: B60K28/06
Filed: 1984-03-06
Abstract: The detector is fitted to the steering wheel of the motor vehicle and requires that the driver continuously exerts a light pressure with his fingers if the alarm is not to be activated. Should the driver release his grip, whether through fatigue or illness, an electric circuit is broken and initiates an alarm sequence which proceeds to an emergency stop sequence. Various measures may be taken; sounding the horn, activating a warning in the driver's compartment, energising the stop lamps, turning off the fuel supply, or operating the brakes.

A profile pawl is supported at one of the ends of the drum and cooperates with a shock absorber and an elastic abutment to brake the drum at the end of one revolution and hold it in readiness for a subsequent pull on the material.  An eccentric lever is secured a the other end of the drum and is engaged by a spring such that in a first portion of rotation of the drum, the spring absorbs energy and after a dead point, it releases its energy to drive the drum in rotation.  The drum has a longitudinal slot and a cutting member is pivotably mounted in the slot and carries a follower which cooperates with a fixed cam such that the cutting member is retracted in the drum in an inoperative position and projects from the slot in the drum in the operative position to produce a cut across the entire width of the material while the latter is maintained in tension on both sides of the cutting member.

Abstract: Abstract A semiconductor device, such as a transistor, integrated circuit or the like, having a pattern of oxidized and densi-fied porous silicon regions extending onto one of its major surfaces for isolating regions of the semiconductor is manu-facturable by a relatively simple process.  The process in-volves forming porous silicon regions in the surface of the semiconductor body such as a silicon wafer, in the areas where dielectric isolation between semiconductor devices is desired.  The porous silicon regions are then oxidized at a temperature sufficient to completely oxidize the porous silicon.  The oxidation is such that the oxidized porous silicon extends above the surface of the semiconductor wafer. The oxidized porous silicon regions are then subjected to a temperature higher than the oxidizing temperature utilized in the previous step to cause the densification of the oxi-dized porous silicon regions.  The result of this densifica-tion step is the collapse of the porous oxide to the dense structure which is substantially planar with the surface of the semiconductor wafer.  This densified silicon dioxide structure has an etch rate which is substantially the same as thermally grown silicon dioxide.

Abstract: ABSTRACT         Demineralized crude water is distilled during flow along first t path which is defined by sationary parts.   Such water is evaporated and thereafter cooled and condensed by  heat transfer medium which is circulated along an endless second path.  Evapora-tion of crude water results in condensation of the medium, and con-densation of resulting water vapors into distillate results in evap-oration of the medium.  The medium is caused to pass through a heat pump which raises its pressure and temperature before the thus heat-ed medium  exchanges heat with and evaporates crude water in the first path.  The medium and/or the distillate can be used for pre-heating crude water upstream of the evaporting station, and the vapors are preferably purified by one or more cyclones, by an elec-trostatic filter and/or by ultrasonic waves intermediate the avap-orating and condensing stations.
