Patent EP-0169172-A3 (EP)
Title: Driving tool for fastening elements, such as nails, staples etc.
IPC: B25C5/16
Filed: 1985-07-15
Abstract: A device for driving fastening elements, such as nails, staples and the like, includes a magazine extending transversely from a driving unit. A follower is located within the magazine for supplying fastening elements to the driving unit. For filling the magazine with fastening elements, the follower can be secured in a loading position. The follower is secured by a stop pivotally attached to the follower which engages an abutment on the magazine. The follower is released from the loading position by an actuating member movably mounted on the magazine so that it can contact an engagement part on the follower and pivot the stop out of engagement with the abutment.

Title: A light fixture preferably for candlelight
IPC: F21S13/00
Filed: 1986-01-15
Abstract: A light fixture (1), preferably for candlelights (4), comprises a plurality of arms (2) interconnected about a vertical symmetrical axis (3) and preferably made of metal wire. The arms (2) are pivotably interconnected about the vertical symmetrical axis by means of a separate, rigid, and preferably elongated holder (5). Thus the arms (2) can be locked in predetermined angular positions by means of at least one loose annular locking means (6, 7) when the candelabrum (1) is used, whereas said arms (2) can turn freely about the symmetrical axis (3) and thereby be folded towards one another in such a manner that the light fixture (1) is flattened when the locking means (6, 7) are removed. In this manner a simple light fixture (1) is provided, the arms of which can be turned in a simple manner about a symmetrical axis after removal of one or more locking means and thereby be folded towards one another in such a manner that the light fixture in an advantageous manner only takes up little room when put away or transported.

Abstract: Zur Verbindung einer Förderschnecke (24) mit einer axial und 
radial antreibenden Spindel (31) greifen diametrale, radial 
geführte, federbelastete Schieber (35g) in eine Ringnut der 
Förderschnecke (24) ein. Die Schieber (35g) sind mittels eines 
Spreizkeiles (35d) aus der Ringnut steuerbar, welcher Spreiz­
keil (35d) durch einen Radialzylinder (30) zwischen die Schieber

richtung bei einer der Arbeitsrichtung des Radialzylinders 
(30) entsprechenden Stellung der Schieber (35g) sowie einer 
formschlüssigen Radialkupplung (R) beendet werden. Durch die 
Verwendbarkeit von radialen Schiebern (35g) und einer form­
schlüssigen Radialkupplung (R) ergibt sich eine extrem robuste

Patent EP-0189270-A3 (EP)
IPC: B29C48/10
Filed: 1986-01-15
Abstract: Polymer blends comprising a continuous matrix phase of 
thermoplastic polymer with a discontinuous phase of ther­
moplastic polymer distributed through it are produced by ex­
truding a blend of immiscible thermoplastic polymers through 
an annular extrusion die which subjects the polymer blend to 
transverse shear forces prior to passing through the die lips. 
The application of the shear forces to the polymer blends pro­
duces improved uniformity of distribution of the continuous 
phase within the matrix, producing better properties in the 
finished article which may be a blown film or a blow molded 
product. The continuous matrix phase is suitably a polyolefin 
such as polyethylene and the discontinuous phase may be 
selected to provide the desired properties in the extruded arti­
cle, for example, vapor barrier properties, strength, stiffness, 
and tear resistance. Typical polymers for the discontinuous 
phase are polyamides, EVA copolymers, polyacrylonitrile, 
polystyrene and various copolymers. The annular extrusion die 
which is used has an annular flow passage between two 
relatively moving walls in which the resin blend is subjected to 
the shear forces which promote the distribution of the con­
tinuous phase in the matrix.

Abstract: In laser equipment as disclosed, which is intended for 
medical use, a number of laser devices (1) of the semicon­
ductor type are ranged in succession one alongside the next 
such that the axes of the relative beams (2) emitted are 
disposed substantially parallel and lie within a common

(2) emitted by the laser devices (1) into a corresponding 
number of emergent beams (5) the cross-sections (6) of 
which each exhibit one dimension significantly greater than 
the other. The beam cross-sections lie in close proximity one 
to the next, aligned end-to-end through their longitudinal 
dimension, thereby forming what is substantially a con­
tinuous section of laser radiation in the form of a thin strip

Title: Method and apparatus for avoiding failures caused by contacts-welding in heating and cooling systems
IPC: G05D23/19
Filed: 1987-08-21
Abstract: A bidirectional heat transfer system including a reversing valve and a compressor has a compressor control which is subject to a welded contact failure. The system is monitored to determine when the control system has signaled for the compressor operation to stop but the compressor has, in fact, continued to operate. Under these circumstances, a safety mode of operation is commenced to keep a load on the compressor to thereby save the compressor from self-destruction. Preferably, this is done by repetitively reversing the state of the reversing valve.

Title: Method and circuit arrangement for connection and control in a cordless telephone
IPC: H04W84/10
Filed: 1987-12-10
Abstract: To verify that the handset of a cordless telephone unit is still within the radio coverage area of the fixed station, rather than attempt to establish connection with the switched network and verify contact as a result of receiving a dial tone, or dialing a special number in the network, a user can merely activate a radio coverage verification circuit in the handset and fixed station. Through use of these circuits, in addition to the identification number of the station, a code is transmitted. The identification and code, when received by the opposite station, are verified with number and code values stored in that station, and the number and code are then retransmitted as an acknowledgement signal. An annunciator in the handset provides a visual or aural warning to the user if the acknowledgement signal is not received, indicating that the handset is not within the radio coverage area of the fixed station.

Title: Semiconductor device having a constricted current path
IPC: H01L27/04
Filed: 1988-12-19
Abstract: The invention relates to an electric element, 
whose conductance is quantized in units 2e²/h realized 
in a multi-dimensional charge carrier gas, which is 
provided with a part of reduced width having a width of 
the order of the Fermi wavelength and a length smaller 
than the average free path length. Due to the small width 
of the part of reduced width, the energy levels are sub­
divided, as a result of which, at a temperature at which 
the distance between the levels is comparable with kT, 
the charge transport through the constriction is determined 
by quantum-mechanical effects. For the charge carrier gas, 
for example, a two-dimensional electron gas near a GaAs-­
AlGaAs hetero-junction may be used, for example, in a 
voltage divider.

Abstract: A syringe disposal aid 10 comprises a tube-like 
container 12 having one rounded closed end 14 and one 
open end 16 closed by a screw threaded removable lid or

slot 20 having a relatively wide section 22 and a 
relatively narrow section 24, for engagement with a

section 22 of the slot 20. Slideable displacement of 
the syringe 26 causes engagement of the sheath's flange 
36 with the narrow section 24 of the slot 20 thus

of the syringe therefrom.

Patent EP-0351546-A3 (EP)
IPC: F24J2/04
Filed: 1989-06-14
Abstract: A solar collector for the generation of high temperatures including a tub-like housing defining a cavity, a glass plate for sealingly closing the cavity, a selective absorber and a trasparent thermal insulation structure located on the inside of the glass plate. An air gap separates the selective absorber from the glass plate. The solar collector is operated at a vacuum of less than 10000 pascal by means of a vacuum pump. The transparent thermal insulating member reduces the air convection and acts similarly to a mulitple pane for the reflected, diffuse thermal radiation. High efficiencies are thus achievable even at large temperature difference between the absorber and the area outside the solar collector. The thermal insulation effect of the air gap and at the same time of the microporous thermal insulation located in the bottom of the housing is varied by regulation of the degree of vacuum. A higher air pressure results in greater thermal losses of the absorber toward the thermal insulation member and the microporous insulation, whereby the temperature of the absorber is controllable.
