Patent EP-0188240-A3 (EP)
IPC: H04N5/232
Filed: 1986-01-10
Abstract: An apparatus for continuously determining the position 
of best focus of an objective lens (12) and a system having a 
video output is disclosed. The technique uses a transmissive 
plate (16) of variable thickness located on one side of the 
field stop (14) of the optical system associated with the video 
output. The plate covers the full vertical field of the system 
and covers on the order of 30 to 40 resolution elements in the 
horizontal direction. The plate is divided vertically into 
platelets (48) of different thicknesses which are distributed in 
such a way as not only to cover the range of defocus of the 
system, but to discriminate against possible variations in 
scene content. The plate is placed outside the active area 
which will be displayed by the video; therefore the variations 
in thickness and in focus introduced by the plate are not 
displayed on the video, but are only used for the purpose of 
continuously determining the position of best focus. A 
spherical shell (13) of zero power may be placed between the 
objective lens (12) and the field stop (14) in order to create a 
bias so that focal shifts introduced by the plate (16) may be 
distributed about a nominal position, rather than all in a 
positive direction.

Title: Digital recursive filter
IPC: H03H17/04
Filed: 1986-05-02
Abstract: The invention relates to a digital recursive filter in a state space structure, the weighted input signal (2) being supplied to delay sections, the output signals of which are in each case fed back weighted to their input and in each case weighted to the input of the other delay section and are combined weighted to form the output signal (second-order filter block), with predetermined signal word length, in fixed- or floating-point arithmetic, and is characterised by the fact that after each weighting, the signal is subjected to a cutting or rounding operation, that the input or output signal of the delay sections is in each case subjected to a saturation characteristic and that the input or output signal of the delay sections or of the limiters or the combined signals fed back to the input of the delay sections are in each case subjected to a signal correction in that in the case of a negative signal, two quantisation steps q are added to the latter. <IMAGE>

Patent EP-0291575-A3 (EP)
Title: Horizontal deflection transformer
IPC: H01F27/30
Filed: 1987-12-03
Abstract: Horizontal deflection transformers for television sets which are used in conjunction with a circuit for voltage multiplication predominantly consist of two coil formers, pushed coaxially into one another, with separate primary winding and pushed-on high-voltage winding. Such a construction is elaborate and the pulse duration to be utilised is considerably reduced at an operating frequency of over 20 kHz, for example 32 kHz. The novel deflection transformer is intended to exhibit a simple construction and the voltage multiplication circuit should operate correctly with a frequency of, for example, 32 kHz and more. In order to use a horizontal deflection transformer for television sets for generating high voltage in conjunction with a voltage multiplication circuit at frequencies of much over 20 kHz, a particular allocation of particular winding areas of the primary winding to particular winding areas of the high-voltage winding is required. The horizontal deflection transformer having the novel winding configuration is also suitable for operating frequencies of 64 kHz in conjunction with a voltage multiplication circuit. <IMAGE>

Patent EP-0232121-A3 (EP)
IPC: C08B37/02
Filed: 1987-01-28
Abstract: An absorbent material comprises cross-linked poly­
saccharide fibres having covalent chemical cross-links 
between hydroxyl groups. The polysaccharide is water-­
soluble in its non-cross-linked state, for example 
dextran. The fibres are water-insoluble but are capable 
of absorbing at least twice their weight of water to 
form a swollen gel.  
     The fibres can be produced by dissolving a carboxy­
late ester of the polysaccharide in an organic solvent, 
preferably with a latent cross-linking agent for the 
polysaccharide, extruding the solution through a jet 
into an aqueous medium to form fibres and subjecting 
the fibres to conditions which cause hydrolysis of the 
ester groups in the polysaccharide and cross-linking 
of the hydroxyl groups so formed by the latent cross-­
linking agent.

Title: An apparatus for quantitatively extruding food material
IPC: B30B11/20
Filed: 1988-02-23
Abstract: Food material is introduced into a space (27) formed between the periphery of a drum (9) and the wall of a housing (7). The drum has an inner chamber (31) between its inner wall and the periphery of a cam (19). A pair of blades (15) is inserted into slits (13) formed on the drum so as to form a compartment on the outside of the drum and a compartment in the inner chamber (21). The dimensions of the outer compartment decrease towards the exit port (23), while those of the inner compartment increase, so a pressure differential is established and any air in the material is drawn into the inner chamber via a recess (17) on the trailing surface of the blade (15). Material of a uniform quantity and density, and that has no air entrainment, is thus extruded from the exit port.
Patent EP-0290199-A3 (EP)
IPC: H01H69/00
Filed: 1988-04-28
Abstract: A resettable, current-responsive, circuit interrupter 
device has two wide but thin terminals embedded up to a 
substantial part of their thickness in a side wall of an 
insulating housing so that sides of the embedded terminal portions 
are exposed from the housing material along the side wall inside 
the housing. Terminal ends extend from the bottom of the housing 
to be connected in a circuit and extend through the top of the 
housing to be accessible for test purposes. An electrical contact 
is mounted on the exposed side surface of one embedded terminal 
portion and a thermostatic strip element is secured to the exposed 
side surface of the other embedded terminal portion to extend 
closely along the one housing side to normally engage the contact 
in a very compact, closed circuit position of the device. A lid 
overlies the thermostatic strip element. The thermostatic strip 
element has a selected resistivity and the wide terminals have 
substantial current capacity so the thermostatic strip self-heats 
to a selected temperature to open the circuit in response to 
occurrence of a precisely predetermined overload current condition 
in the device circuit at any ambient temperature likely to be 
encountered in an automotive environment.
Patent EP-0292176-A3 (EP)
IPC: C09K3/00
Filed: 1988-05-09
Abstract: Complexes of a transition metal and a tetrasubstituted 
aromatic compound which contain at least two transition metal atoms. 
At least two of the substituents are -SH groups, the other two 
substituents being -SH, -OH and -NHR. The complexes are prepared by 
reacting the tetrasubstituted aromatic compound with a transition 
metal compound in the presence of a disubstituted aromatic compound. 
Depending on the relative proportions of the di- and tetra-­
substituted compounds, the resulting complex may contain more than 
one residue from the tetra-substituted compound and more than two 
transition metal atoms. The complexes possess infra-red absorbing 
properties which vary in dependence on the particular complex, the 
complexes with more than one residue from the tetrasubstituted 
compound absorbing radiation of longer wavelength. The compounds 
can be used to provide infra-red absorbing compositions, for example 
as a coating or inter-layer for glass. The complexes may be used 
together with one or more different infra-red absorbing materials. 
The tetra-substituted aromatic compound may be a tetra-thiol and this 
can be prepared from an aromatic compound containing at least four 
halogen substituents by reaction with an alkaline thiol compound in 
the presence of iron and sulphur in a polar solvent such as dimethyl 
formamide.

a central mixing chamber between the nozzle and the arc 
chambers within the anode and coupled to a central 
powder feed (72). The powder feed includes a replaceable 
insert which includes at least one and preferably a 
plurality of powder feed ports into the various arc 
chambers. Alternatively, metal which has already been 
heated to a molten state can be fed directly into the 
central mixing chamber. The modular cathodes which are 
independently powered by separate D.C. power sources (99A, 
99B, 99C) are also independently cooled by separate cooling water 
systems as is the common anode. The cooling systems are 
configured to produce swirling of the cooling water so
