Patent CS-255931-B1 (CS)
Inventor: CHRISTOV NEDELCO
IPC: F02F1/04
Filed: 1986-04-11
Abstract: Řešení se týká oboru metalurgie a
řeší problém výroby válce ze dvou částí,
s cílem zdokonalení mechanického spojení
obou částí za účelem zvýšení životnosti
spoje a zlepšení přestupu tepla. Podstata
řešení spočívá v tom, že obě části
válce se po odmaštění očistí v inertní
atmosféře, pak ee sešroubují a ohřívají
a během ohřevu se dotahují a po dosažení
teploty nižší, než je teplota tavení
nejníže tavitelného složkového kovu, se
na této teplotě udržují po dobu dlfuzního
svařování, načež se ochladí na vzduchu
na teplotu 293 K.

k uvedeni tranzistoru do stavu saturace,
přivádíme proudové tvarové inpulsy o energii
nutné pro stav saturace, které uvedou
tranzistor do stavu saturace, přičemž kolektorový
proud na měřícím odporu vytvoří
tvarové impulsy, charakterizující vadný
tranzistor. Emitor tranzistoru je připojen
na zemnici hrot, jehož vývod je spojen se
zemi, na bázi tranzistoru je připojen budící
hrot, jehož vývod je spojen s generátorem

Abstract: A data processing system includes a central processing unit (CPU), a main memory unit, and input/output (I/O) sockets, each adapted to receive a selected one of a plurality of different and/or similar option cards. Each card contains (or is connected to) and controls a respective peripheral device, and each card is pre-wired with an ID value corresponding to its card type. Programmable option registers on each card store parameters such as address information, priority levels, and other system resource parameters. A setup routine, during initial power-on, retrieves and stores the appropriate parameters in the I/O cards and also in socket locations in main memory, one location being assigned to each input/output socket. Each socket location is adapted to hold the parameters associated with the card inserted in its respective socket and the card ID value. That portion of main memory containing the socket locations is adapted to maintain the parameter and ID information by means of battery power when system power fails or is disconnected, i.e., a non-volatile memory portion. Subsequent power-on routines are simplified by merely transferring parameters from the memory to the card registers if the status of all the sockets has not changed since the last power-down.

Abstract: An important characteristic in obtaining meat from poultry carcasses is, in preparation for this, the handling of the carcass in the area of the clavicle (4), where the problem to be solved is to ensure that, even in cases where the clavicle is broken, that breast pieces of this do not remain in the breast meat. This problem is solved by inserting a shaped block (18) into the V-shaped section of the clavicle, said shaped block having in plan view a wedge shape, the flanks of which are provided with slot-like grooves (26), into which the branches of the clavicle can fit, so that these disappear into the grooves. The clavicle can then be scraped clean on its outside surface, by means of scraper knives (32) guided over the flanks of the shaped block, without the danger that any broken pieces will be picked up and lifted out.
