Title: Dispensing gun
IPC: B05B7/24
Filed: 1989-10-06
Abstract: A dispensing gun, in particular a multi-component spray gun (1), is indicated, to which at least two components are supplied via separate pipes (31, 32) which are connected to gun channels (10, 11) in the dispensing gun. In such a dispensing gun, the problem was experienced in the past that a pipe arranged in the front region of the gun exerts a torque on the gun, which directs the dispensed jet, in particular the spray jet, downwards. With the new gun, working is to be easier and more fatigue-free. To this end, the pipes (31, 32) are joined to an intermediate piece (16) which has intermediate channels (17, 18) and is mounted rotatably in a bore-hole (45) in the dispensing gun, the intermediate piece (16) providing the connection of each pipe (31, 32) to the gun channel (10, 11) assigned to it irrespective of the relative rotational position of intermediate piece (16) and dispensing gun (1).

Abstract: A novel process for purifying crude 1,2-bis(nicotinamido)propane obtained by the reaction of nicotinic acid with 1,2-propanediamine. This process comprises forming 1,2-bis(nicotinamido)propane dinitrate from the crude 1,2-bis(nicotinamido)propane, suspending the dinitrate in an organic solvent, adding an alkali or an alkaline solution to the suspension to dissociate the free 1,2-bis(nicotinamido)propane, extracting it from the suspension with a solvent, and removing the solvent to isolate the purified product. According to this process, crude 1,2-bis(nicotinamido)propane can be efficiently purified to give the product having a high purity.
Patent EP-0323447-A3 (EP)
IPC: B03B11/00
Filed: 1987-05-21
Abstract: To separate minerals, they are made up into a slurry A 
applied via a distributor ring 211 to a hollow tapered cylinder 
spinning on its axis to generate 10g centrifugal force.  
     The cylinder widens at a half-angle of 1°, and its axis is 
inclined at 2° upwardly in the direction of widening.  
     A film of slurry is held centrifugally to the internal 
surface of the cylinder. The denser (i.e. higher specific 
gravity) particles in the slurry tend to move preferentially 
radially outwardly (centrifugally) and to move downwardly in the 
boundary layer (under Earth's gravity). The action of the 
washing water B is to displace waste accidentally entrained with 
the higher-specific-gravity-particles.  
     The valuable higher-specific-gravity particles overflow 
downwardly continuously at C and are collected. The washing water 
and lower-specific-gravity waste particles move upwardly towards 
the top edge of the cylinder at C, but are repeatedly swept 
downwardly by staggered vanes 213 rotating faster than the 
cylinder. The water and light particles therefore overflow at C 
but only after numerous 'attempts' each of which improves the 
reliability of the separation.

Title: Non-linear comb filter for color tv receivers
IPC: H03H15/00
Filed: 1989-03-22
Abstract: A comb filter for separating chrominance and 
luminance signals for each sample of a video signal 
adaptively selects exactly one line above or one line 
below for processing with the sample of interest. 
In the process, luminance and chrominance signals are 
obtained for both processing modes and coupled to a 
switch. Selection logic utilizes the chrominance signals 
established for each mode to sequentially check vertical 
correlation of the video signal, chrominance variations, 
and vertical detail to position the switch to choose the 
proper luminance and chrominance signal pair.
Patent EP-0336511-A3 (EP)
IPC: C12P35/02
Filed: 1989-03-31
Abstract: The present invention relates to a new method of 
protection of the carboxy group in the chemistry of the 
compounds of β-lactam type. According to such a method, 
the carboxy group is protected by being transformed into 
its corresponding phenyl-acetoxy-methyl ester, which is 
then removed by an enzymatic route by means of 
penicillinacylase.  
     In particular, if the β-lactam compound also bears a 
phenyl-acetamidic substituent, this latter is 
simultaneously hydrolysed during the same step of removal 
of the carboxy function protecting group.

Title: A method for the preparation of a carrier for a zieglernatta polymerization catalyst, a carrier prepared using the method, and its use in a polymerization catalyst system
IPC: C08F4/02
Filed: 1989-09-11
Abstract: The present invention relates to a method for the preparation of a reactive carrier for a Ziegler-Natta type polymerization catalyst. In the prior-art carrier preparation methods the focus has been mainly on improving the reactivity of the carrier by grinding or on preparing the carrier in specific reactivity-enhancing conditions, but the methods have been expensive and the results have not always been satisfactory. In the present invention, the reactive carrier is prepared by   a) causing the untreated carrier and a substance complexable with it to react with each other in order to form a particulate, thermally decomposable complex compound or complex salt, and b) treating the thus formed complex compound or complex salt with heat in order to separate the complexable substance in part or completely from the carrier, which is thereby rendered reactive. f

Patent EP-0402578-A3 (EP)
Title: Improved apparatus for measuring the voltage applied to a radiation source
IPC: H05G1/26
Filed: 1990-03-20
Abstract: Apparatus is provided for use in detecting the input 
voltage applied to a radiation source (10) operating at an 
unknown voltage within a given voltage range. The apparatus 
includes a set of radiation absorbing filters (F1, F2) including a 
first filter which includes a first chemical element and a 
second filter which includes a second chemical element. 
These elements are chosen so that the filters exhibit 
different radiation absorption characteristics within the 
given voltage range. The filters are adapted to be 
positioned so that the first and second filters are 
irradiated by the radiation source (10) with the radiation (18) 
impinging upon a surface of each filter and partially 
absorbed thereby as it passes therethrough so as to exit 
therefrom as attenuated radiation. A detector (20) receives the 
attenuated radiation passed by the first and second filters 
and provides first and second signals (I₁, I₂) having magnitudes 
which vary with the attenuated radiation respectively passed 
by the first and second filters. A ratio (34) is determined as 
to the magnitude of the first signal to that of the second 
 
 
signal with the magnitude of the ratio varying with that of 
the input voltage. At least one of the first and second 
elements (F1, F2) exhibits a known K absorption edge within the given 
voltage range. Consequently as the input voltage is 
increased to exceed the known K absorption edge that 
chemical element exhibits a greater attenuation 
characteristic to extend the useful range of the 
relationship of the magnitude of the ratio and the input 
voltage.

Title: Apparatus for applying a liquid-film to a material web
IPC: B05C5/00
Filed: 1991-08-07
Abstract: In a liquid-application unit operating according to the refilling principle, the liquid which is to be fed via hoses is to be distributed uniformly over the working width. This took place previously by means of a reservoir space which is advantageously formed from a conically increasing retaining space, out of which the liquid runs onto the material web via an overflow edge and a guide surface. However, it is also essential with this low-volume liquid retaining space that the liquid be supplied uniformly over the working width, in particular when changing colour. In order to achieve this, individual liquid distribution spaces which extend one directly next to the other over the working width are defined in which uniformity is achieved by means of a forced distribution of the liquid from a feed opening to a number of outflow openings. This forced distribution takes place similarly to the structure of a family tree, namely in steps from one opening to two, four, eight, sixteen outflow openings and so on.
