Patent EP-0169468-A3 (EP)
Title: Electronic switching apparatus, preferably working without making contact
IPC: H03K17/945
Filed: 1985-07-13
Abstract: An electronic switch of the type having two external lines, one of which is connected to one pole of an operating voltage source in series with a load and the other of which is connected with the load. The switch comprises a sensor, e.g. an oscillator, responsive to proximity of an object thereto and has an output transistor operated by the sensor with blocking and conductive states selectively controlled by the transistor in response to the oscillator. A MOS-FET power transistor is in series with the output transistor and, to reduce the voltage drop in a conducting state of the electronic switch, a self-conducting MOS-FET is used as the MOS-FET power transistor.

Patent EP-0171934-A3 (EP)
IPC: G06F12/02
Filed: 1985-07-17
Abstract: A method and apparatus for managing a block oriented 
memory (40, 42, 44) of the type in which each memory block 
(14-16, 20-23, 30-32) has an associated reference count 
representing the number of pointers to it from other memory 
blocks and itself. Efficient and cost-effective implementation 
of reference counting alleviates the need for frequent 
garbage collection, which is an expensive operation. The 
apparatus includes a hash table (83) into which the virtual 
addresses of blocks of memory which equal zero are 
maintained. When the reference count of a block increases 
from zero, its virtual address is removed from the table (83). 
When the reference count of a block decreases to zero, its 
virtual address is inserted into the table (83). When the table 
(83) is full, a reconciliation operation is performed to identify 
those addresses which are contained in a set of binding 
registers associated with the CPU (10), and any address not 
contained in the binding registers are evacuated into a 
garbage buffer for subsequent garbage collection opera­
tions. The apparatus can be implemented by a cache 
augmented by the hash table (83), providing a back-up store 
for the cache.

Title: Method and means for sealing
IPC: B29C61/06
Filed: 1985-08-21
Abstract: An aperture, for example a duct having a cable passing through it, is sealed by installing a laminate, comprising an adhesive layer, a heater layer, and a heat-recoverable foam layer, the thickness of which increases on heating, into the gap between the duct wall and the cable with the adhesive layer facing both the wall and the cable. On energizing the heater, the foam increases in thickness and forces the adhesive into sealing engagement with the wall and cable.

Patent EP-0201680-A3 (EP)
IPC: H01H37/54
Filed: 1986-03-06
Abstract: Ein Thermoschalter besitzt eine kreisförmige, konkav 
oder konvex gekrümmte Bimetallscheibe, die sich mit ihrem 
Rand auf einem Gehäuseteil abstütz und deren zentraler 
Bereich direkt oder indirekt eine Kontaktzunge beaufschlagt. 
In ihrem zentralen Bereich weicht die Bimetallscheibe vom 
Krümmungsradius ab, insbesondere entsteht dadurch eine 
gegenläufige konkave bzw. konvexe Krümmung mit einem 
kleineren Krümmungsradius. Durch diese spezielle Formge­
bung wird bei Unterschreitung der Rückstelltemperatur das 
Rückspringen verhindert, was bei bestimmten Anwendungs­
fällen nicht mehr erwünscht ist. Durch dieses Verhalten ist 
der Thermoschalter ausschließlich durch mechanische Ein­
wirkung von außen wieder in seinen Ausgangszustand 
zurückzuversetzen, die erfindungsgemäße Formgebung 
beeinträchtigt aber das ordnungsgemäße Ansprechen der 
Bimetallscheibe bei Erreichen der Schalttemperatur nicht.

Title: Bait for animals
IPC: A23K1/10
Filed: 1987-03-23
Abstract: A prefabricated animal bait containing a carrier substance and a pharmaceutically active substance, for example, a vaccine against rabies. The carrier substance contains a fat component and an additive to stabilize the shape retention of the bait, with both components being selected in such a manner that the mixture is pasty for processing and does not break in the temperature range in which it will be used. The bait is produced in such a manner that, in a deep-drawn mold, the carrier substance completely surrounds, and envelopes a pre-assembled unit of the active substance so that the bait merely needs to be pressed out of this carrier foil when it is to be used. Economical industrial production of prefabricated bait in a simple manner, easily and optimally adaptable to the respective animal species and its habitat with respect to temperature and moisture is provided. A particular simlification results from the use of fish meal as the additive since it simultaneously acts as a lure.

Filed: 1987-05-09
Abstract: A drive torque limiter comprises a wheel-shaped driving 
member (18) having a center hole (34) which is sized 
for a substantial slip fit over a driven shaft (36). 
A friction plate (38) is located on at least one side 
of the driving member; the friction plate (38) rotates 
without slippage with the shaft (36,40). Locking means 
(44,46) are provided for preventing the driving member 
and the friction plate from sliding longitudinally on 
the shaft. A spring (48) biases the driven member and 
the friction plate together.  
     An annular-ring surface (50) is located on the friction 
plate (38) or the driving member (18) or both. The 
annular-ring surface is substantially concentric with 
the driven shaft (36,40) and forms an annular-ring 
interface between the friction plate and the driving 
member. The transmitted torque between the driving 
member and the driven shaft is limited by frictional 
force between the friction plate and the driving 
member at the annular-ring interface.

Abstract: A high-strength spring steel which produces 
retained austenite less than 10 % in content by weight 
after quenching in steps of quenching tempering, and

Title: Semiconductor memory device
IPC: G11C29/00
Filed: 1987-03-18
Abstract: A semiconductor memory includes a plurality of cell blocks, a refresh control circuit which sequentially refreshes a plurality of the cell blocks, an access control circuit which accesses a plurality of the cell blocks, and an ECC circuit which is provided in a data path between the access control circuit and the plurality of cell blocks, so that the data which is input from and output to the access control circuit is converted to a predetermined bit converted data (so called code) by the ECC circuit and is stored in the plurality of cell blocks. Accordingly, when the access control circuit accesses the plurality of cell blocks, if the access cannot be carried out for specified cell block which is in a refresh state (that is, a correct data (code) cannot be written to or read from the cell block in a refresh state) the data in the access control circuit side can be reproduced as correct data by the ECC circuit. Therefore, viewed from the external, a predetermined access can be carried out without being affected by the refresh state.
