Title: Programmable sense amplifier for read only memory
IPC: G11C16/02
Filed: 1988-08-23
Abstract: A programmable sense amplifier in accordance with 
the present invention includes an input multiplexer 
which receives a plurality of data input signals from 
the column lines of a ROM and provides a selected one 
of a data input signals as a data output signal based 
on control signals provided to the input multiplexer. 
The voltage level of the data output signal corresponds 
to the number of 1's contained in the selected column 
line. A sensing stage receives the data output signal 
and amplifies it. The amplified signal is then 
provided to an XOR gate which either does or does not 
invert the amplified signal, based upon the state of 
the select node to which one of the XOR gate inputs is 
connected. The state of the select node is determined 
by a programmable internal multiplexer. The internal 
multiplexer comprises a number of FET switching 
transistors corresponding to the number of data input 
signals. Each of the switching transistors has one of 
its electrode areas commonly-connected to the select 
node. The other area of each switching transistor is 
selectively, i.e. programmably, connected either to the 
negative supply V SS  or the positive supply V CC  
depending upon whether or not, respectively, a number 
of "1"s contained in the selected column line exceeds 
one-half the total number of row lines of the ROM, the 
1s and 0s in the selected column line having been 
inverted if this is the case. Thus, the select mode 
will be appropriately charged or discharged because the 
XOR gate to produce the correct sense amplifier output.

Patent EP-0276168-A3 (EP)
IPC: A61G1/007
Filed: 1988-01-22
Abstract: There is disclosed a container (1) of a size suitable 
for accommodating a human body and comprising two trough-­
shaped members (3, 5) detachably connected together by a 
number of fasteners, and having seals (15) arranged along 
the free edges (13) of the members (3, 5). Each seal (15) 
comprises a U-shaped portion (36) into which a respective 
edge flange (13) is received, a hollow D-shaped elongate 
portion (37) which is resiliently deformable upon closure 
of the container so as to make sealing contact with the 
hollow elongate portion (37) of the other seal, and sealing 
lips (33) projecting from the outer surface (39) of the 
hollow elongate portion (37) and laterally deformable into 
sealing contact with the sealing lips (33) and/or the outer 
surface (39) of the hollow elongate portion of the other 
seal upon closure of the container. One side of the U-­
shaped portion (36) is formed by a resilient flange (31) 
which can be deformed laterally to allow each seal (15) to 
be fitted over the edge flange (13), and the flange (31) 
terminates in a lip (38) which is located at the transition 
(40) between the outer surface (41) of the main body of 
each half (3, 5) of the container and its free edge flange 
(13). This forms a smooth transition between the outer 
surface (41) and the flange (31) so as to facilitate 
handling, and to minimise the risk of the seal becoming 
dislodged in service.

Abstract: Die Sensoreinrichtung besitzt eine Sensorkopf (1) mit einem 
Oszillator (4), dessen Frequenz in Abhängigkeit von der Ver­
änderung einer Sensorkapazität oder -induktivität (5) va­
riiert. Die Oszillatorschwingungen werden über ein Koaxialka­

welche die Frequenzänderungen auswertet. Der Sensorkopf (1) 
enthält ferner Temperaturmessmittel (R T , T), welche einen 
temperaturabhängigen Speisestrom verbrauchen. Der Speise­
strom, der über das Koaxialkabel (3) zugeführt wird, wird in 
der Auswerte- und Bedieneinheit (2) gemessen und in einer 
Messschaltung (11) in ein Signal umgewandet, das die Tempera­
tur des Sensorkopfes (1) angibt. Dieses Signal wird verwen­
det, um über eine Mikroprozessor-Steuerschaltung (7) eine 
steuerbare Spannungsquelle (13) einzustellen, die die Speise­
spannung über das Koaxialkabel (3) zum Sensorkopf (1) lie­
fert. In diesem beeinflusst die Höhe der Speisespannung eine 
steuerbare Reaktanz (C S ), die im Schwingkreis des Oszillators 
(4) angeordnet ist. So kann durch die von der Temperatur des 
Sensorkopfes (1) abhängigen Aenderungen der Speisespannung 
die Temperaturabhängigkeit der Oszillatorfrequenz ausge­
glichen werden.

IPC: C01F7/0606
Filed: 1989-03-30
Abstract: A method of transferring heat between process 
liquor streams, such as streams of caustic liquor in the 
Bayer process for producing alumina from bauxite, uti­
lizing a heat pipe arrangement for heat exchange. The 
process streams respectively pass in contact with one 
surface of a first heat-exchange wall and one surface of 
a second heat-exchange wall while being isolated from 
the second surfaces of the two walls; these second walls 
are exposed to a closed volume (also isolated from both 
process streams) containing a heat transfer fluid that 
vaporizes below the temperature of the hotter process 
stream and condenses above the temperature of the cooler 
process stream. The heat transfer fluid vaporizes at 
the exposed surface of the wall contacted by the hotter 
stream, and condenses at the exposed surface of the wall 
contacted by the cooler stream, thereby transferring 
heat (as heat of vaporization) from the former stream to 
the latter.

Title: Food product manufacture

Filed: 1989-11-07
Abstract: A sweet or savoury filling for a sandwich or 
pastry is based on an oil/fat-in-water emulsion 
containing at least one emulsifying protein, salt and 
whey powder. The inclusion of both salt and whey 
powder has been found to lead to the desirable 
properties of a moist mouthfeel and sufficiently-low 
water content for a baked product containing the 
filling to be shelf-stable for an extended period at 
ambient temperature. By the use of a combination of 
two emulsifying proteins (sodium caseinate and soya 
protein isolate) a filling is obtained which is stable 
to the baking step but which undergoes controlled 
breakdown upon re-heating and provides further 
desirable mouthfeel characteristics.
