Patent EP-0103467-A3 (EP)
IPC: G02B6/34
Filed: 1983-09-08
Abstract: A fiber optic data distribution system for transferring data 
between a plurality of terminals (72, 74, 76, 78). Each terminal 
is connected to a dedicated portion of separate fiber optical 
material (111a, 111b, 111c, 111d) and may be uniquely 
addressed by encoding the optical signal with a distinct ad­
dress code. Optical signals may be supplied from a central pro­
cessing unit (67) to one or more terminals (72, 74, 76, 78). Al­
ternatively, an optical signal may be supplied by a terminal (72, 
74, 76, 78) and transmitted to another terminal (72, 74, 76, 
78), or the central processing unit (67).

being in communication with the exhaust gases, and the 
tuating member and pumping member being movable 
through their first stroke during the pressure-increasing 
phase of each pressure pulsation and being moved through 
their second stroke by a first non-linear variable-rate spring 
means 60 during each pressure-decreasing phase of each 
pressure pulsation during low to intermediate engine 
speeds and loads and by both the first and a second non-­
linear variable-rate spring means 62 during intermediate to 
high engine speeds and loads, whereby the pump assembly 
is operable to pump air from the source throughout a wide 
range of engine speeds and loads including high speeds 
and loads.

Patent EP-0132644-A3 (EP)
IPC: H04L12/413
Filed: 1984-07-05
Abstract: Transceivers interface between a multiple access bus and 
user devices, for transferring variable length data packets 
between the devices. Each transceiver buffers only one byte 
of data at a time while sending or receiving a packet. A general 
purpose computer in the device performs various functions 
ancillary to byte transfers. Data signals on the bus are in 
bit-serial asynchronous baseband form. Each byte group of 
bit signals is preceded by a pair of stop and start signals 
whose transition forms a time reference for reception of those 
bits. The timing of the stop signals is tailored to operating 
characteristics of the device computers and their assigned 
ancillary functions. Access controls in each transceiver start a 
timeout sequence when the signal on the bus changes to the 
stop level and and reset when the level reverses to the start 
level. If the times level persists longer than the time allotted 
for transmitting one start-stop pair and a data byte, the timer 
activates a "bus available" indication enabling the respective 
receiver and user device to begin sending a packet if ready to 
do so. New activity on the bus causes the bus available indica­
tion to be reset and an interruption to be represented to the 
user computer. The computer reacts by conditioning the 
device and adapter to either receive or ignore the incoming 
packet, depending on destination information in the packet 
header. The timer threshold can be varied to adapt user 
devices to various modes of multiple access operation.

Title: Digital audio transmission
IPC: H04M11/06
Filed: 1984-11-15
Abstract: @ A digital sub-band coder for audio signals provides for adaptive allocation of bits to (eg) two sub-bands. Estimation of the relative energy content of the bands is determined by reference only to those bits which are always transmitted, so that decoding can take place without the need for transmission of side information. Accompanying data may be transmitted in a fixed bit position, or may be by insertion of the data into the lower energy band. In the latter case, the data may optionally be duplicated in both bands when their energy contents are random. The invention can be applied to embedded ADPCM coders.

Abstract: A novel liquid filter of the "outside-in" type is disclosed, 
comprising a hollow tubular housing, a concentrically dis­
posed perforated tubular core surrounded by a cylindrical 
filter element and communicating with a liquid outlet in the 
bottom wall of the housing, and a filter element cap covering

tubular housing with high resistance to rupture under 
pressure is claimed. The filter of the invention is particularly 
suited for use in extracorporeal blood flow circuits, most 
particularly as an arterial blood filter located downstream 
from a blood oxygenator.

Abstract: An electric switch with a set of stationary contact means 
and a set of movable contact means situated on a contact 
bridge (30) movable between an IN-position and an OUT-­
position comprises furthermore a forcibly guiding mecha­
nism (32) for manual handling of the contact bridge (30) as 
well as an ejector mechanism (56) and a trip device (74) co­
operating with said ejector mechanism, whereby the contact 
bridge (30) is automatically displaced from its IN-position to 
its OUT-position when an overloading, a fault or a signal 
current is present.  
     The forcibly guiding mechanism (32) and the contact 
bridge (30) are interconnected by means of a releasable 
blocking device in such a manner that the ejector mechanism 
(56) in the releasing situation need only overcome frictional 
forces between the stationary and the movable contact 
means as said blocking device is released by means of the 
trip device (74).  
     Furthermore the forcibly guiding mechanism (32) and the 
ejector mechanism (56) co-operate in such a manner that the 
latter containing an energy reservoir such as for instance a 
spring (64) is automatically reset before the contact bridge 
(30) can be forced to the IN-position.  
     The forcibly guiding mechanism (32) - in the form of an 
elbow joint - moves between two extreme positions and dur­
ing said movement it passes a dead centre. Furthermore it 
comprises a tilting spring (40) the content of potential energy 
of which after the passage of the dead centre is utilized for 
charging the energy reservoir (64) of the ejector mechanism 
(56).

Title: Fuel injection for internal-combustion engines
IPC: F02M57/02
Filed: 1986-05-13
Abstract: A fuel injection apparatus which the termination of the effective pump supply stroke is effected by exposing a relief conduit with the aid of a valve having for instance a control edge, whereupon a highly pressurized fuel flows out via the relief conduit and is directed into a pressure chamber defined by a rear face of a pressure valve closing member. The pressure valve closing member is located in a connection with a fuel injection line that leads from the pump work chamber to the fuel injection valve and is acted upon by a valve spring to effect closing of this injection line. The impact of fuel that reaches the pressure chamber via the releif conduit reinforces a fast closure of the pressure valve closing member at the end of injection, which leads to an abrupt termination of an injection cycle. In addition, or altenatively, the fuel injection valve closing member can also be acted upon by the impact of fuel diversion.

Abstract: Several conveyor rollers of singulators are made to 
rotate by a fruit orientation belt causing fruit carried 
thereon to rotate in accordance with movement of the belt 
such that the rotational axes of the fruit, typically lemons, 
orient themselves along their stem axes, or substantially 
perpendicularly to the direction of travel of the 
singulators. Downstream, the rollers contact a rotating 
spin-accelerating belt to substantially increase speed of 
rotation of the rollers and oriented fruit thereon in order 
to permit optical scanning devices to scan a much larger 
percentage of the fruit surface areas. Fruit rotate in the 
same direction of rotation during orientation and 
spin-acceleration, the latter occurring for only a very short 
duration.

Abstract: An open-back baffle loudspeaker having a higher 
baffle cut-off frequency and a lower resonant frequency 
of possibly 25-50Hz. The loudspeaker is made with a 
relatively high "Q" (e.g., between 2 to 4) so that the 
effect of the "Q" on amplitude counteracts the effect of 
baffle roll-off, thus causing the amplitude of the output 
of the loudspeaker to remain substantially constant from 
the baffle cut-off frequency to the resonant frequency. 
The result is a loudspeaker which can more faithfully 
reproduce relatively low frequency sounds.
