Abstract: It is necessary to supply electronic components 
to a precise location in a transfer station 26, the compo­
nents being supplied in a plurality of magazines 22 e.g. 
for a component placement machine. Desirably the magazines 
may be readily exchanged without significant time being 
taken in setting up the magazine position accurately. 
Suitably the magazines are mounted on a turntable 24 each 
magazine having a location mark 362 positioned accurately 
relative to a transfer position 286. Drive means 264 moves 
the turntable 24 to present the transfer position 286 of 
the magazine 22 at the transfer station 26 and sensing 
means 358 senses the mark 362 when the supply means 18 is 
in a characterising mode. Information supplied by the 
sensing means 358 determines when the transfer position 286 
is at a precise location of the transfer station 26. When 
the supply means 18 is in an operational mode, the transfer 
position 286 of the magazine is presented at the precise 
location of the transfer station 26, directly.

Patent EP-0295774-A3 (EP)
IPC: B02B3/00
Filed: 1988-04-27
Abstract: Significant improvements to the milling of wheat 
kernels are possible by sequentially removing the bran layers 
of the kernels prior to processing in general accordance with 
conventional milling principles. The wheat kernels are 
preprocessed by means of a number of friction and abrasion 
operations to peel or strip the various layers of bran from the 
kernels. A series of friction machines (208,215,218) followed by abrasion 
machines (224,230) progressively remove the bran layers and separate the 
same into generally pre-identified bran layer mixtures. Up to 
about 75% of the bran can be removed with the remaining bran 
being essentially confined to the kernel crease and removed 
during the conventional milling operation. Such preprocessed 
kernels, when milled in the conventional manner, have higher 
yields due to less bran contamination. This selective removal 
of the bran layers also facilitates low cost production of 
speciality bran products or selective reintroduction of bran 
layers to flour after, or during, further milling.

Title: Arrangement for an arrester device
IPC: B64F1/02
Filed: 1988-05-03
Abstract: An arrangement for use in conjunction with aircraft 
arrester devices of the kind which comprise upper and lower, 
essentially horizontal edge elements (1 and 2), which edge 
elements are connected together by essentially vertical transverse 
elements (3) by means of coupling devices (5), for the purpose of 
protecting the transverse elements against the absorption of 
moisture, with an associated weight increase and rigidity at 
sub-zero temperatures.  
     Each transverse element (3) is enclosed by a hose- or 
stocking-like protective sleeve (7), which on the one hand is so 
arranged as to interact in a sealing fashion at its ends with 
adjacent parts of the arrester device in such a way that water and 
moisture are prevented from finding their way into the element, 
and on the other hand is executed from a semi-permeable material 
of a kind, such as GoreTex®, which is impermeable to water, but 
allows water vapour to pass through, so that any moisture which, 
in spite of every precaution, has managed to be absorbed by the 
transverse element (3), can evaporate into the surroundings.

Title: Analog-digital converting circuit having high resolution and low power consumption
IPC: H03M1/00
Filed: 1989-04-20
Abstract: An analog-digital converting circuit comprises an analog 
amplifying circuit having an input connected to an analog signal input 
terminal and having a plurality of outputs for generating a corresponding 
number of analog signals amplified by different amplification factors. A 
first selector is connected at its a corresponding number of inputs to 
receive the plurality of amplified analog signals, respectively. The first 
selection circuit outputs one analog signal selected from the received 
amplified analog signals, to an analog-digital converter. A second 
selector is connected at its an input to receive a digital signal from the 
analog-digital converter and has a plurality of outputs for outputting the 
received digital signal from one sequentially alternatively selected from 
the plurality of outputs. A coefficient multiplying circuit has a 
corresponding number of inputs connected to the plurality of outputs of 
the second selector, respectively, and a plurality of outputs for generating 
a corresponding number of multiplied digital signals which are obtained 
by the plurality of outputs of the second selector by different coefficients, 
respectively. A third selector is connected at its corresponding number of 
inputs to the plurality of outputs of the coefficient multiplying circuit so 
as to output, as a digital signal, one selected from the plurality of outputs 
of the coefficient multiplying circuit. A controller is connected to receive 
the plurality of outputs of the second selector for monitoring respective 
levels of the plurality of outputs of the second selector and for supplying a 
selection signal to the third selector so as to cause to select, from the 
plurality of outputs of the coefficient multiplying circuit, one multiplied 
digital signal in correspondence to a level of the analog signal.inputted to 
the analog signal input terminal.

Title: Synchronising fractional tap equalisation with received signals
IPC: H04B3/04
Filed: 1989-07-14
Abstract: In a modem receiver having a fixed sample rate relative to incoming 
symbols and a tapped delay adaptive equaliser with fractional tap 
spacing, coefficients used in the equalisation computations are rotated 
relative to a reference tap in order to compensate for relative drift 
between incoming signals, representing real (i.e. non-training) data, 
and the clock controlling sampling. By itself, such rotation would 
tend to distort received data by shifting the sampling phase away from 
the centre of the received symbols. Logic means included herewith 
operates to prevent such distortion, so that the integrity of the data 
output of the receiver is unaffected by the rotation. In the disclosed 
embodiment, such logic means operates to shift the phase of the "sum of 
products" computation (product of data and tap coefficients) relative 
to the flow of data into the fractionally spaced delay network. Since 
the present receiver does not require synchronisation with incoming 
symbols it is well adapted to function in environments where such 
synchronisation would be difficult to provide; for example, in 
situations where data transmitted at various baud rates is received via 
a digital carrier trunk and requires equalisation or comparable filter 
processing.

Patent EP-0387471-A3 (EP)
Title: An electrically controlled cold and hot water mixer faucet
IPC: G05D23/13
Filed: 1989-08-02
Abstract: The invention relates to an electrically controlled mixer 
faucet for cold and hot water, in which the control member 
determining the mixing ratio is moved by an electric motor 
(7). The purpose is to achieve temperature control which is 
for the user more convenient than earlier, and an initial 
temperature which is independent of the previous user. The 
control of the motor (7) is dependent on a target detected 
between a source of light (19) and a photocell (20) by the 
photocell (20). If the photocell (20) does not detect a 
user, the motor control circuit (13) receives its reference 
value from a circuit (18) the signal given by which has 
been set in advance. It is possible to produce by means of 
a suitable delay circuit (22) a certain delay before this 
signal is switched on. If there is a user in the detection 
field of the photocell (20), the control circuit (13) re­
ceives its control signal via the press-buttons (14, 15) 
used by the user and via corresponding circuit means (16, 
17) which form control signals. The control circuit (13) 
receives a signal corresponding to the actual value of 
temperature via a temperature sensor (23) installed in the 
water mixing space.
