Title: An improved coil package
IPC: B65D85/04
Filed: 1985-08-01
Abstract: An improved coil package comprises a closable carton 21 formed from a folded blank of cardboard and having a pair of oppositely disposed major side walls 22, each of which has an aperture 23 in axial aligment with the aperture of the other major side wall and, removably housed in the carton, a reel on which is carried a coil of wire (not shown). The flanges 34 of the reel have apertures 37 of diameters less than the apertures 23 in the major side walls 22 of the carton and end parts 40 of a rigid hollow hub 39 formed of a transversely folded metal strip protrude from the reel flanges and are so rolled radially outwardly that their extreme edges bite into the outer faces of the reel flanges, no portions of the rolled over end parts of the hub protruding beyond the planes containing the outer faces of the major side walls.

Filed: 1985-08-08
Abstract: A telescopic strut comprises a sealed cylinder (10) 
containing a fluid, a piston (12) fitted in the cylinder and 
sealed to the cylinder wall, and a hollow piston rod (20) 
extending from one side of the piston (12) and having a 
closed end (22) which extends out of one end of the cylinder. 
A hollow actuating rod (26) extends axially of the strut 
through the piston (12) to communicate with the hollow 
piston rod (20) and extends at its closed end through the 
other end of the cylinder. A valve (34) is operable by axial 
displacement of the actuating rod (26) to open and close fluid 
communication from one side of the piston (12) to the other, 
to vary the effective length of the strut.

Title: Sanitary armature
IPC: F16K47/02
Filed: 1987-07-17
Abstract: A sanitary outlet fitting contains an opposing pressure element (22) between a mixing valve and an outlet (14). The said element (22) has an element which can be deformed or moved under the pressure of the water released by the valve, which builds up an opposing pressure. The build-up of the opposing pressure reduces the pressure drop at the output of the mixing valve and thus the amount of noise produced.
Patent EP-0259665-A3 (EP)
IPC: H01R4/24
Filed: 1987-08-19
Abstract: Bei elektrischen Anlagen, insbesondere bei Kraftfahr­
zeugen, werden häufig Verbinder benötigt, um elektrisch 
leitende Verbindungen zwischen Kabelenden herzustellen, 
beispielsweise für die Stromversorgung eines Autoradios 
oder auch für den Lautsprecheranschluß. Die bekannten 
Verbinder weisen den Nachteil auf, daß sie auf engstem 
Raum - etwa hinter dem Armaturenbrett eines Kraftfahr­
zeuges - nur schwer zu handhaben sind, weil für das Her­
stellen der Verbindung zusätzliche Werkzeuge erforderlich 
sind. Außerdem müssen die Kabelenden zuvor abisoliert 
werden.  
     Bei dem neuen Verbinder ist es demgegenüber lediglich 
erforderlich, die Kabelenden (24) durch die Öffnungen (22) eines 
Gehäuses in einen Hohlraum einzuführen, welcher eine 
Kontaktfeder (20) mit Federenden besitzt. Wenn die Kabel­
enden nach dem Einführen kurz in entgegengesetzte Rich­
tung (A, B) bewegt werden, schneiden sich die Federenden durch 
die Isolierung in die Kabelenden ein, wodurch über die 
Kontaktfeder eine elektrisch leitende Verbindung herge­
stellt wird. Dabei sind keine zusätzlichen Werkzeuge er­
forderlich.

Patent EP-0255207-A3 (EP)
IPC: F24C7/02
Filed: 1987-05-26
Abstract: A microwave oven has a hot air system for forcing a flow 
of hot air through the oven cavity and a magnetron for 
delivering microwave power to the cavity. The oven 
distinguishes between foods in a first category (including 
baked food items) from foods in a second category 
(including frozen food items and items cooked in high-­
sided metal containers). Discrimination between 
categories is achieved by sensing the hot air temperature 
after a predetermined time (such as 6 minutes) from the 
commencement of cooking, and terminating cooking when a 
threshold temperature appropriate to the sensed category 
is attained.
Patent EP-0260872-A3 (EP)
IPC: E01C13/08
Filed: 1987-09-09
Abstract: The back-loops (26) of the stitches of pile yarn 
(12) of a tufted carpet (10) are fastened to the 
backing (14) by thermal bonding, obviating the need for 
applying an adhesive coating to the underside of the 
backing. Preferably, the thermal bonding is 
accomplished by using a pile yarn (12) made of or 
incorporating a synthetic thermoplastic material, e.g. 
polyethylene, which becomes tacky at a temperature 
below that at which the backing (14), e.g. nylon, is 
adversely affected. The backing (14) acts as a 
sufficient thermal barrier or heat sink as to prevent 
damage to the face pile (24) during application of heat 
to the underside of the backing while conducting the 
thermal bonding step. Where other backings and coating 
are omitted, a tufted carpet of superior porosity may 
be made, e.g., for use as a sand-filled (38) artificial 
turf.

Patent EP-0306603-A3 (EP)
Title: Lighting fixture with at least one tubular fluorescent lamp
IPC: F21V11/02
Filed: 1988-04-05
Abstract: Each fluorescent lamp (1) is assigned a louvre system consisting of a parabolic longitudinal reflector (2) and numerous crossblades (3) consisting in each case of two parabolic limbs. The aim is for the light to be brought from the lamp indirectly in an oblique direction onto a workplace via the crossblades. So that light cannot be emitted directly between the crossblades (3), the gaps are covered, on the one hand by cover plates (4a) parallel to the lamp which adjoin in each case the base of the crossblades, and over the remainder by cover plates (4b) which are likewise parallel to the lamp but are arranged in an upper plane at a slight distance from the lamp. Without appreciably changing the basic design of the lighting fixture, it is possible to determine the extent and direction of the indirect light reflection by a wider or narrower construction of the upper cover plates or by overlapping. For the rest, it is also possible for the lower cover plates (4a) to be used to emit light by radiating (6) upwards via an opening (2a) between the longitudinal reflectors. <IMAGE>

Title: A liquid fluorocarbon and a method for producing the same
IPC: C10C3/02
Filed: 1989-10-25
Abstract: Disclosed is a novel fluorocarbon comprising carbon 
atoms and fluorine atoms and having no double bond, the 
atomic ratio of fluorine to carbon atoms being 1.50 to 
1.93, which exhibits a liquid state at room temperature. 
The liquid fluorocarbon has excellent water- and oil-repel­
lent properties and can advantageously be used, for 
example, not only as a water- and oil-repellent but also as 
an inert liquid, a heat transfer agent and a vapor phase 
soldering liquid in various fields, especially in the elec­

directly from a pitch or from a pitch fluoride which can be 
obtained by direct fluorination of a pitch.
