Title: Pressure-chamber grinder
IPC: B02C19/06
Filed: 1982-11-25
Abstract: A pressure-chamber grinder which comprises a grinder chamber (1) of substantially circular section, which chamber is provided with a feed opening (3) for the material to be ground, fed as a gas-tight plug, and the opposite end of which chamber is provided with an outlet opening (5) for the material ground. Tangentially directed grinding-gas nozzles (7) are fitted as uniformly spaced around the entire circumference of the mantle face (6) of the grinder chamber, or at least of part of same. The object of the present invention is to force the entire material flow to rush into every grinding zone. This has been achieved so that the grinder chamber (1) is, by means of a partition wall (8), divided into a pre-grinding chamber (9) and a grinding chamber (10) proper, the said chambers being interconnected by means of at least two Laval nozzles (11) passing through the partition wall and forming an angle with each other, whereat the material-gas jets rushing through these nozzles at a supersonic speed collide against each other at the outlet side of the Laval nozzles (11), thus forming there a grinding zone, to which zone the coarse fraction separated in a classifier (17) connected to the outlet opening (5) of the grinding chamber (10) is returned.

Abstract: A shallow water drilling or production barge (46) is 
adapted for offshore use by means of a novel drydock (40) 
which has wing walls (52) of substantial freeboard and a 
platform (74) of essentially no freeboard. Jacking legs (42) 
extend down through the wingwalls to the sea bed (50). 
Valves (56) in the wing walls are opened to allow them to 
partially submerge and lower the platform enough to float 
the barge into place; and then jacking mechanisms in jacking 
towers (54) on the wing walls are operated to raise both the 
drydock and the barge up out of the water. The barge rides or 
rails (75) supported by roller assemblies on the platform; and 
after being raised the barge is pulled forewardly and locked 
in place.

Patent EP-0116710-A3 (EP)
IPC: G06F7/50
Filed: 1983-12-15
Abstract: An improved circuit for performing high speed arithme­
tic computations is described, and includes a mechanism for 
dynamically deleting faulty data bits in a configuration for 
minimizing propagation delay paths. The invention is parti­
cularly applicable to an associative processor wherein the 
data word length and rate of flow of data may vary from one 
instruction to the next. In accordance with the invention, data 
propagation delay time is minimized as is the number of 
required circuit interconnections, thereby making the inven­
tion easily manufacturable on an LSI chip. The advantages of 
the circuit design are multiplied in an associative processor, 
since such processors are highly reconfigurable and must be 
able to exclude unwanted bits from an arithmetic operation, 
to change data word sizes and to delete failed bits. The 
present invention is advantageously implemented in arith­
metic carry circuits and in cascaded multiplexer logic 
circuits, which may effectively be implemented in MOS 
(metal oxide semiconductor) integrated circuits, or in CMOS 
(complementary MOS) integrated circuits in which a plurality 
of stages of such circuits must be connected in series, i.e. 
eight, sixteen, thirty-two, etc., while still providing a rapid 
execution speed.

Title: System and method for automatically testing integrated circuit memory arrays on different memory array testers
IPC: G01R31/319
Filed: 1984-09-05
Abstract: A system for automatically testing a plurality of memory 
arrays (25A...25X) on selected memory array testers 
(21A...21X) includes an interactive data entry device (12) for 
entering array test specifications (20A...20N) including cha­
racterizing information, DC testing parameters, AC testing pa­
rameters and AC test pattern choices for the array. The test 
specifications are entered in a format which is independent of 
a particular tester's characteristics. A universal language gen­
erator (14) generates a tester independent universal language 
instruction sequence (16) for carrying out the prescribed tests 
based upon the entered test specifications. Associated with 
each tester is a language translator (19A...19X) which trans­
lates the tester independent universal language instruction se­
quence into an instruction sequence which is particular to the 
associated tester (21A...21X). The tester dependent instruc­
tion sequence (30A...30X) may be loaded into the associated 
tester to produce the test signals for testing the memory array 
(25A...25X).

IPC: F16J15/32
Filed: 1985-10-16
Abstract: Improved lubricant control assemblies for reciprocating 
piston rods of an engine which prevent crankcase lubricant 
intruding into the cylinders and fluid from the cylinders from 
escaping into the crankcase. Each assembly comprises a tubular 
scraper fitting closely onto a piston rod and yieldably mounted 
within the bore between cylinder and crankcase through which 
the piston rod extends. The yieldable mounting is by means of a 
compliant housing. The compliant housing allows the scraper to 
be displaced radially and thereby follow limited radial displace­
ment of the piston rod while maintaining substantially full effec­
tiveness of the scraper's action on the reciprocating piston rod. 
The scraper is urged into forceful contact around the piston rod by 
means of a crown spring which is supported on a tubular part 
which attaches to the compliant housing. The compliant housing 
comprises an outer ring portion which is threaded into the bore to 
mount the assembly on the engine and an inner ring portion which 
attaches to the tubular part. One or more intermediate ring 
portions may be included in the compliant housing. Each ring 
portion joins to its immediate ring portion(s) at only one axial end 
with the points of joining alternating axially from each ring to the 
next. A disclosed embodiment for the compliant housing com­
prises a one piece nylon part.

Title: Fluid pressure sensor with temperature indicator
IPC: F16H61/00
Filed: 1986-04-11
Abstract: A pressure sensor (33) is provided by a bridge circuit on a 
semiconductor diaphragm (44), with diaphragm deflection be­
ing effective to produce an output voltage proportional to the 
deflecting force. A constant current source (62) is coupled to 
the energizing terminals of the bridge circuit. By measuring the 
voltage drop across the semiconductor bridge during opera­
tion, an output signal indicative of bridge temperature is ob­
tained. Accordingly two output signals, pressure (32) and tem­
perature (35), are derived from a single bridge sensor (33). This 
produces a compact, accurate transducer assembly for use in 
an automotive control system, providing two control signals 
from a single sensor structure.
