Title: Metal fitting
IPC: E04B1/26
Filed: 1985-12-11
Abstract: A metal fitting for forming an end connection of a wooden beam, such as a roof beam or purlin, to a supporting structure, which may also be a wooden beam, such as a main beam or truss, characterized by a web having opposite bearing surfaces, one bearing surface engaging a surface of the supporting structure and the other surface engaging the end of the beam. The one surface has an arrangement, such as a supporting flange extending perpendicular thereto, for mounting the fitting on the support structure. To mount the beam, the fitting has at least one leg extending perpendicular from the other bearing surface having a constant thickness and being provided with a groove-like attenuation to separate the leg into a supporting portion and a free end portion, which free end portion has openings for receiving fastening elements. The attenuation prevents the transfer of forces extending parallel to the web being applied to the free end portion from being transmitted to the web, but allows tensile forces to be transferred to the web of the fitting.

Patent EP-0227466-A3 (EP)
IPC: H02G1/12
Filed: 1986-12-22
Abstract: A wire stripper having a two-part hollow body (1) and a 
group of circular cutters (34,35,36) mounted within a cassette 
(12) in the body. The two body parts are inter-connected for 
relative movement between an open position, and a closed 
position at which the cutters are engageable with and pen­
etrate into a cable end portion (5) positioned within the body. 
Locating means (3,19,49) functions to properly position the 
cable end portion (5) within the body. The cutters are spring 
biased so as to be movable into and out of a position at which 
they have maximum penetration in the cable end portion. A 
cable end stop fixes the axial position of the cable end portion 
and is movable into an inoperative position in response to the 
body parts being moved into the closed position. A handle 
(14) is rotatably connected to the body (1) and includes a re­
leasable retainer (20) which is engageable with the cable (6) 
to hold the cable against movement relative to the handle. 
Each cutter (34,35,36) is operative to form a respective circu­
mferential cut around the cable end portion (5) as a consequ­
ence of relative rotation between the body (1) and the handle 
(14) while the body parts are in the closed position. Stripping 
of the end portion is effected by removing the cable (6) from 
the body (1) while the body parts are in the closed position.

Abstract: Die Erfindung betrifft eine Schaltungsanordnung für eine 
Fernsprechanlage, bestehend aus einer Hauptsprechstelle 
und mehreren Nebensprechstellen, zwei Amtsleitungen und 
einem zentralen Wecker. Alle Einheiten sind über die vor­
geschriebene sechzehnpolige Postanschlußdose zu verbin­

rät (N), aus welchem zwei unterschiedliche Betriebsgleich­
spannungen und eine Rufwechselspannung gewonnen werden. 
Diese Spannungen werden über einen Mikrocomputer (M) gesteuert 
und müssen daher ein gemeinsames Bezugspotential haben. Aus 
diesem Grund müssen nach bekannter Schaltungsanordnung 
fünf Anschlußpunkte auf der Anschlußdose für das Stecker­
netzgerät belegt werden. Aufgabe ist es, mit drei Anschluß­
punkten auszukommen und dafür eine weitere Nebensprechstel­
le anzuschließen. Dies erfolgt durch Verlegen der Gleich­
richter- und Regeleinheit in die Hauptsprechstelle und 
eine Entkopplung der abgeleiteten Rufwechselspannung, so 
daß ein gemeinsames Bezugspotential für alle drei Span­
nungen gewonnen werden kann und diese durch den Mikrocom­
puter gesteuert werden können.

Patent EP-0257441-A3 (EP)
IPC: C08G18/48
Filed: 1987-08-11
Abstract: The present invention is a flexible 
polyurethane foam which is prepared in the one-shot 
reaction of a reaction mixture comprising 
diphenylmethanediisocyanate or a derivative thereof 
having an average functionality of 2.0 to 3.0, a 
relatively high equivalent weight polyol or mixture 
thereof having an average functionality of 1.7 to 2.1, 
and a blowing agent.  
     This invention permits the use of MDI in the 
production of one-shot polyurethane foam. In preparing 
molded foams, this invention permits the ready 
manufacture of very complex parts such as automobile 
crash pads and dashboards. In slabstock foams, this 
invention permits the use of cheaper, lower equivalent 
weight polyols to prepare a foam having equivalent 
properties to a TDI-based foam. It often permits the 
preparation of lower density foam for a given amount of 
 
 
blowing agent, and provides for a smaller average cell 
size, which has been related to improved physical 
properties.

Title: Exchanging apparatus for the screw cylinder of an injection-moulding machine
IPC: B29C45/17
Filed: 1987-10-27
Abstract: A changing device for the screw cylinder of an injection molding machine. The screw of the screw cylinder is in releasable coupling connection with a drive unit of the machine. For releasing and uncoupling the coupling connection, the screw cylinder including screw can be displaced relative to the injection molding machine essentially transversely of the longitudinal direction of the screw cylinder. Two hydraulic cylinders are arranged spaced apart next to each other symmetrically and parallel to the longitudinal center plane of the injection molding machine. The two cylinders are connected to each other by means of a transverse member. A free space extending forwardly from the drive unit is defined by the two hydraulic cylinders and the transverse members. The free space forms an alignment seat which is open towards the front and towards the back and a longitudinal side. In the coupled position, the screw cylinder is fixable and lockable to the drive unit in this alignment seat. The free space forming the alignment seat of the changing device is open toward the bottom, so that the transverse member which connects the hydraulic cylinders acts on the upper longitudinal side of the hydraulic cylinders.

Patent EP-0267647-A3 (EP)
IPC: H04L9/26
Filed: 1987-11-05
Abstract: The invention relates to a method of enciphering 
information-containing digital data signals with the aid of 
enciphering keys and of deciphering a message thus 
enciphered, utilizing the same key. For usages in which high 
demands are made on the quality of enciphering the 
conventional method - the EX-OR adding together of clear text 
and key text on a bit basis - has shortcomings. The invention 
has for its object to provide a very reliable method with 
which furthermore the propagation of errors caused by any 
transmission errors is prevented. This is accomplished in 
that the (clear) text characters to be enciphered are 
processed using an enciphering key which is derived from a 
key text and that the nature of the processing operation 
performed on the clear text characters is determined by an 
instruction command which is also derived from the key text.

Title: Transparent cache memory
IPC: G06F12/02
Filed: 1988-05-24
Abstract: Transparent cache memory for data processing system in which a central 
processing unit requests the read out of an information contained in a 
working memory at a current address and immediately receives, whithout 
waiting, the requested information from the cache memory, if the 
requested information contained in the cache memory and meanwhile the 
cache memory performs the reading and the storing into the cache, of an 
information contained in the working memory at the address next 
following the current address, so as to advance a possible subsequent 
request of the central processing unit.  
     If the requested information is not contained in the cache memory, the 
cache memory performs a double memory read in page mode at the current 
memory address and at the next following address, thus minimizing the 
occupation times of the memory. The double reading is performed only for 
those addresses which allow for page mode operation.
