Patent EP-0286288-A3 (EP)
Title: Swathe scanned imager
IPC: H04N5/33
Filed: 1988-03-28
Abstract: Scanning imagers often comprise a plurality of 
detector elements which may be scanned in swathes to 
produce an image. To match the offsets or sensitivities 
of such elements the mean values of the channels adjacent 
each swathe boundary are compared, and an error signal 
produced which is fed back to equalise the values across 
each boundary. Proportionally smaller corrections are 
applied to the intermediate channels in each swathe. In 
this way the swathing or banding effect often associated 
with such imagers is much reduced.
Patent EP-0303494-A3 (EP)
Title: Clock signal generation system
IPC: H04N9/804
Filed: 1988-08-11
Abstract: A television receiver includes a phase-locked loop (PLL) (226-232) which generates a clock signal (CLK) having a frequency of N times the line frequency and being phase-locked to the horizontal line synchronizing signal (HSYNC). The clock signal produced by this PLL has a frequency which tends to jitter between N+1 and N-1 times the line frequency. To compensate for this jittering in the frequency of the clock signal, phase alignment circuitry (236) is coupled to the PLL to align the phase of the clock signal to the horizontal drive signal (HD) produced by the PLL on the occurrence of each horizontal drive pulse. The PLL may also include a delay element (234) which delays the horizontal drive signal applied to the phase comparator of the PLL. This delay element effectively advances the phase of the horizontal drive signal and the line-locked clock signal with respect to the horizontal sync signal to compensate for signal processing delays imparted in the generation of the horizontal drive signal and the clock signal.

Title: Internal gear machine
IPC: F01C17/02
Filed: 1988-09-12
Abstract: An internal gear machine of the kind having variable displacement fluid chambers formed between an orbiting outer gear (33) and a rotating inner gear (31) has the orbiting outer gear (33) retained in its orbiting motion by a plurality of roller dowells closely fitting in a locating ring (19) disposed radially outside the outer gear (33) and extending therefrom to be received in arcuate recesses on the radial outside of the outer gear (33) as it orbits. The locating ring (19) is connected to an end piece (15) of the internal gear machine along a plane of torsional stress and this connection is reinforced by providing the end piece (15) with recesses (45) disposed coaxially with the roller dowells (41) and extending the roller dowells (41) closely within the recesses (45). The roller dowells (41) thus extend across the plane or torsional stress and provide reinforcement.

Title: Protection arrangement of a deflection circuit
IPC: H04N5/63
Filed: 1989-03-04
Abstract: A deflection switch (Q1) of a horizontal 
deflection circuit (250) is coupled to a retrace resonant 
circuit (100) that includes a horizontal deflection winding 
(L H ) and a first retrace capacitance (C₁). A flyback 
transformer primary winding (W₁) is coupled to a junction 
terminal (collector of Q1) of the deflection switch (Q1) 
and the retrace resonant circuit. An East-West modulation 
current is generated by a bidirectional second switch (Q2) 
having a conduction time that is phase modulated during 
horizontal retrace at a vertical rate in a parabolic 
manner. The second switch (Q2) is coupled in series with 
the deflection switch (Q1) during the entire trace 
interval. To prevent an over-current condition when the 
current in the second switch (Q2) exceeds a predetrermined 
first level, the second switch (Q2) is turned off and 
interrupts the flow of current through the deflection 
switch (Q1). Additionally, a diode (D₁) is coupled 
between an intermediate terminal of the transformer primary 
winding (W₁) and a ]unction terminal of the deflection (Q1) 
and the second (Q2) switches for preventing an overvoltage 
condition from developing across the second switch (Q2).

Patent EP-0372274-A3 (EP)
IPC: B42D25/41
Filed: 1989-11-16
Abstract: For multicolour marking of identity cards and the like, the multilayer identity card is provided with an outer coloured layer in a first colour and an inner coloured layer in a second colour. While the outer coloured layer absorbs virtually none of the laser light used for marking, the second, inner coloured layer absorbs the laser light. This causes the material in the second coloured layer to be thermally degraded, i.e. evaporated, sublimed or subjected to a chemical or physical reaction, during the marking operation, with the consequence that formation of pressure causes the first layer to be broken up into particles, causing the second coloured layer to become visible. The second coloured layer may also be replaced by a transparent coat of varnish having appropriate properties in order to expose, for example, a multicolour security printed image under this transparent coat of varnish.

Title: Blends of polymers, particularly polycarbonates, acrylate-modified rubber compositions and additional polyacrylates
IPC: C08F291/02
Filed: 1990-05-04
Abstract: The modified rubber compositions comprise by weight 
about 15-60% of a highly saturated aliphatic rubber such as 
ethylene-propylene-diene rubber, about 25-80% of preferably 
non-nitrogenous acrylate monomer units; and less than about 
5% multi-functional monomer units. The compositions exist 
as amorphous heterogeneously dispersed phases. The first 
phase comprises the copolymer rubber to which polymers of at 
least 10%, preferably 20%, and more preferably 30% of the 
other monomer units are grafted. The second phase comprises 
the other monomers polymerized as homo and copolymers, not 
grafted to the rubber. Greater than 10% and preferably 20% 
of the monomer units other than rubber are grafted to the 
rubber. The number average molecular weight of the grafts 
is between 10,000 and 80,000 daltons.  
     The modified rubber composition, additional, preferably 
non-nitrogenous, polyacrylate polymer, and another polymer 
are mixed together to form a polymer blend having higher 
impact strength and other important properties. The other 
polymers are often more expensive and usually have some 
advantageous property compared to polyacrylate. Other polymers 
disclosed are: polycarbonates, SAN, polystyrene, polyvinylchloride, 
polypropylene, polyester, styrene maleic 
anhydride, chlorinated polyethylene, polyethylene terephthalate, 
nylon and ABS. Polycarbonate blends preferably comprise 
a total of at least 35% and up to 65% polyacrylate. 
 
 
The proportion of rubber used to form the graft rubber composition 
to the total graft rubber composition and polyacrylate 
polymer in polycarbonate blends is in the range of 
approximately 2 to less than 30% by weight and preferably no 
greater than 25%.  
     The modified rubber composition is present in polycarbonate 
blends in the range of approximately 6% to 50% by 
weight. The added polyacrylate preferably has a molecular 
weight greater than 80,000 daltons.

such that it surrounds a thermoelectric cooler 16 and a 
radiation detector 18. The shield 40 has a curved 
reflective upper surface 42 having the shape of a toric 
segment and cylindrical or rectangular reflective 
sidewalls 46 for imaging the detector 18 and the upper 
cooler stage upon the tops and sides of lower and warmer 
cooler stages. This beneficially reduces the heatload 
upon the coldest stage by excluding warmer surfaces from 
its view. An aperture 46 defines the effective coldstop 
for the detector 18.
