Patent EP-0199229-A3 (EP)
IPC: B62B5/00
Filed: 1986-04-12
Abstract: Trucks of the rolling container type are frequently used 
for the handling and transport of non-returnable packages 
for, e.g. milk. The trucks generally have three side walls and 
an openable fourth side wall or gate. In the automatic 
handling and loading of rolling containers the handling of 
the gate constitutes a problem, and the gate, moreover, is 
frequently exposed to damage which impairs its function. In 
order to overcome this difficulty, the gate in the rolling 
container in accordance with the invention has been re­
placed by retaining bars which terminate each shelf (7) at its 
free end. The retaining bars (10) extend upwards as well as 
downwards from the shelf plane and thus come into contact 
with the upper as well as the lower end of the packing 
containers placed in the rolling container, as a result of which 
the packing containers are effectively prevented from falling 
off the shelves during the handling of the rolling container.

Patent EP-0247891-A3 (EP)
Title: Phase locked loop system
IPC: H04N9/455
Filed: 1987-05-29
Abstract: A phase locked loop is provided, which may be used in digital systems having clock signal frequency instabilities. The PLL has an analog oscillator (342) the frequency of which is determined by an analog control signal. The oscillatory signal is digitised (344) and phase-compared (338) with a digital reference signal, the digital output of the phase comparator being converted (340) to an analog signal to provide the oscillator control signal. In an application of the invention to a digital television receiver having a line-locked clock, the phase locked loop (350) regenerates two quadrature phase related subcarrier signals (COS,SIN) that are used to synchronously demodulate the chrominance signal components (CB) of the composite video signals into two color information signals (I,Q). The analog voltage-controlled oscillator (342) of the phase locked loop (350) generates a signal that is independent of any frequency instability in the line-locked clock signal. The analog-to-digital converter (344) digitizes this signal to provide one of the subcarrier signals, from which is generated the quadrature subcarrier signal, for example from a read-only memory (348). The two color information signals (I,Q) are obtained by multiplying (332,334) the chrominance signals by the first and second subcarrier signals. The phase comparator (336) determines the phase of the vector sum of the two color information signals and compares this against a desired phase value to generate a phase difference signal. The phase difference signal is filtered (338) and applied to the digital-to-analog converter (340) whichprovides the frequency control signal for the analog oscillator (342). A tracking filter (346) may be inserted at the output port of the analog-to-digital converter (344) to allow its quantization resolution to be reduced without affecting the performance of the phase locked loop.

Abstract: The present invention relates to a printer control system of the 
type which comprises, means for receiving sets of print data, each set 
representing a line of characters to be printed, printing means for 
performing printing operations in order to print each line of characters 
on a print medium in accordance with the corresponding set of print data, 
print data analysing means for analysing each set of data so as to 
generate print instructions for the printing means, and moving means for 
moving the printing means a predetermined amount relative to the print 
medium between successive printing operations in order to print 
successive lines of characters.  
     According to the invention the printer control system is 
characterised in that the print data analysing means detects, in any set 
of print data, data representing a character which is too large to be 
printed in one printing operation, and the moving means is responsive to 
the detection of such large character data to move the printing means 
relative to the print medium a selected distance less than the 
predetermined distance in order for the printing means to be able to 
complete the printing of the larger character by an additional printing 
operation before starting to print the next line of characters.

Patent EP-0287864-A3 (EP)
Title: Movement detector
IPC: G01P13/00
Filed: 1988-03-30
Abstract: When a movement acts on them, movement detectors generate electrical signals, and are therefore suitable both for personal protection and for security against intrusion in buildings. 
<??>The new movement detector comprises inside a housing a Hall-effect element with a magnet arranged therebelow, and a freely movable ball situated thereabove, which is made of magnetisable material. Given a change in position of the sphere, there is a change in the flux density of the magnetic lines of force, and as a result a Hall voltage is generated in the Hall-effect element and indicates the movement. Since the movement is detected electronically, a high sensitivity is guaranteed which, in addition, can be set with simple means, depending on the application.

Patent EP-0278594-A3 (EP)
IPC: H03M1/10
Filed: 1988-01-13
Abstract: The present invention provides a parallel or 
"flash" analog-to-digital converter circuit (A) including a 
plurality of voltage comparators (20a - 20g) arranged in 
first and second sets (F and E) adapted for receiving 
separate analog input signals. A push-pull configuration 
is employed in providing the analog input signal to the 
comparators of the two sets. The analog inputs (22a - 22d) 
of the comparators (20a - 20d) in the first set are 
provided an input signal V₁ and the analog inputs (22e - ­
22g) of the comparators (20e - 20g) in the second set are 
provided an input signal V₂ of equal magnitude but opposite 
polarity. Different reference voltages are provided to the 
reference inputs (24a - 24g) of the comparators by a 
series-connected resistor network (H). Two encoders (I and 
J) and an adder (K) are used to detect the number of output 
signals from the comparators in a similar logic state and 
provide a digital binary output signal corresponding to the 
number of such outputs. The present invention can be 
implemented in an alternative embodiment (L) that includes 
a source (M) of constant voltage which offsets the 
amplitude of one of the input signals V₁ or V₂. This 
enables the use of a simplified resistor network (N) that 
provides reference voltages which can be applied to 
reference inputs of comparators in both sets. The present 
invention can also be implemented advantageously as an 
integrated circuit of compact layout that minimizes cross 
talk among signals flowing through the circuit and thereby 
enhances the precision thereof.
