Patent EP-0238239-A3 (EP)
IPC: F16L47/03
Filed: 1987-03-09
Abstract: A method and apparatus for moulding an assembly of a 
thermoplastics member with a fusion pad 2b such as a pipe 
tapping tee saddle or a pipe coupling. The fusion pad 2b 
has an element which is to be electrically heated to weld 
the assembly to a compatible thermoplastics material and 
this pad is mounted in the cavity 105, 106 of an injection 
moulding tool 100 by which the thermoplastics member is to 
be moulded over the fusion pad 2b. During this latter 
moulding a control system 111 electrically heats the 
element to assist in bonding the thermoplastics envelope of 
the fusion pad to the thermoplastics of the member which is 
being moulded. A wall part 103 of the moulding tool 100 
on which the fusion pad 2b is mounted may be temperature 
controlled 122 to maintain the surface of the fusion pad in 
contact therewith substantially solid.

Patent EP-0298446-A3 (EP)
IPC: G09G5/36
Filed: 1988-07-06
Abstract: A program implemented method converts complex 
graphics and picture images in binary form into bit map 
representations which include only that image data 
which is essential for its reproduction by an output 
printer with limited buffer memory. The method 
includes the steps of storing a group of rows or block 
of the binary image data at a time in an input buffer, 
then analyzing a byte at a time, the row segment of 
image data thereby dividing the row segment into a 
number of cell matrices. Based upon the analysis of 
cell matrices, the method generates bit map 
representations describing only the essential or black 
data. Each bit map representation generated has a 
height corresponding to the number of horizontal scan 
lines and a length which corresponds to the number of 
consecutive cell matrices detected as containing black 
data. Only the essential image data contained in the 
generated bit map representations is transferred to an 
output buffer, along with generated horizontal and 
vertical positioning information, in addition to other 
parameter information required to reproduce the bit map 
representation. The above steps are repeated for each 
row segment or group of data defining each part of a 
page until the entire image has been processed.

Title: Safety box for valuable articles, such as compact discs, records or tapes, as well as a bar means for such a box
IPC: E05B73/00
Filed: 1988-09-14
Abstract: A safety box (10) for sorting, displaying and 
selling valuable articles, such as compact discs, 
records or tapes, in self-service stores with 
electronic theft detection systems. The safety box 
is lockable by a bar means (20) and rendered so 
sturdy that it is practically impossible to remove 
the desired article from the box without a special 
device unlocking the bar means, preferably the 
same type of device used for security tags belonging 
to the electronic theft detection system. Such a 
device is normally positioned at the cashdesk of 
the store. The front side wall of the box can be 
partially open and comprises a border (12 a ) and 
two reinforced corner areas (12 b , 12 c ). The back 
side wall of the box can also be open and comprises 
preferably a border (14 a ) and reinforced corner 
areas (14 b , 14 c , 14 d , 14 e ). Thus a customer can 
clearly see the content of the box. The corner 
areas (12 b , 12 c ) of the front side wall have their 
counterparts in missing corner areas in the back 
side wall (14). Thus the box is suitable for 
stacking. The bar means (20) is locked between the 
borders (12 a , 14 a ) when the article is placed inside 
the box, and is opened by the special device when 
a customer has paid for the article.

Title: Method and apparatus for inspecting resistance to film draw-out
IPC: G01M99/00
Filed: 1989-05-18
Abstract: A method for inspecting resistance to film 
draw-out comprises the steps of holding a magazine in 
which photographic film wound around a spool is 
accommodated, rotating the spool in the direction that 
winds up the film around the spool, detecting the 
movement of a film leader (13a), which has been drawn out from 
the magazine, to the magazine (10), and measuring the force 
required to rotate the spool when the movement of the 
film leader (13a) is detected. An apparatus for inspecting 
resistance to film draw-out comprises a magazine holder, 
and a spool rotation device for rotating the spool in the 
direction that winds up the film around the spool. A 
rotating force measurement (20) device measures the force 
required for the spool rotation device to rotate the 
spool, and a film movement detector detects the movement 
of a film leader, which has been drawn out from the 
magazine, to the magazine. A device receives the output 
of the film movement detector and samples the output of 
the rotating force measurement device when the movement 
of the film leader is detected by the film movement 
detector.

Title: Sorting unit for belt conveyor systems
IPC: B65G47/96
Filed: 1989-07-18
Abstract: A sorting unit for belt conveyor systems is disclosed 
wherein the actuating means of the sorting conveyor belt (4) 
comprise a driving roller (1) axially connected to one of the 
transmission rollers (10,11) between which the sorting belt (4) extends, 
and controlled by an actuating belt (2) friction-coupled thereto by 
means of two counter-rollers (3,3).  
     When the belt (4), upon action of control means (7,8,9), lowers 
laterally for the discharge of the carried object, the contact 
driving roller-actuating belt (2) lacks, thus causing a quasi-in­
stantaneous stop of the sorting belt (4) and therefore a controlled 
trajectory of the sorted object.
Patent EP-0356702-A3 (EP)
Title: Arrangement for monitoring the output flow of a dosing pump
IPC: F04B49/00
Filed: 1989-07-25
Abstract: The upwardly extending outlet of a pump contains a non-floating permanent magnet which tends to assume a lower end position but is propelled upwardly in response to admission of a metered quantity of liquid into the outlet to initiate the emission of a signal by a sensor. The emission of such signal persists as long as the actuator remains above its lower end position. The sensor is connected with the resetting input of a counter by way of an OR circuit. The n-th output of the counter transmits a signal to an alarm signal generating circuit in response to transmission of a certain number of consective timing pulses to its counting input prior to transmission of a signal to the resetting input. The timing pulses are transmitted by a generator which also transmits pulses to the pump to thus determine the frequency of admission of liquid into the outlet. A rectangular wave oscillator receives signals from the sensor and transmits a series of signals to the OR circuit with a delay which equals or approximates the length of the interval between two consecutive timing pulses. The oscillator starts to transmit signals to the OR circuit only if the signal which is emitted by the sensor persists during the aforementioned delay. This ensures that no alarm signal is generated if the viscosity of pumped liquid is so high that the actuator is incapable of returning to its lower end position during the interval between successive admissions of liquid into the outlet.
