Patent EP-0228694-A3 (EP)
IPC: H05K3/40
Filed: 1986-12-23
Abstract: A conductive through-hole is formed through a dielectric 
sandwiched between conductors by forming a noncircular 
hole in a conductor, laser etching a pathway completely 
through the dielectric, liquid chemical or plasma etching the 
dielectric layer adjacent the pathway to undercut the conduct­
ive layer, and deforming at the conductor which has been 
undercut during the etching.
Patent EP-0211570-A3 (EP)
Title: Progressive scan display system with correction for non-standard signals
IPC: H04N7/01
Filed: 1986-07-24
Abstract: In a double scanning receiver including a video speed-up memory with read and write clocks locked to multiples of burst, visible artifacts tend to be produced when displaying non-standard video signals (e.g., from a VCR, gme, computer, etc.) due to skew of the memory clock signals with respect to horizontal sync. Skew artifacts are corrected by delaying (in 95;96,98) the output signal of the memory (50) as a direct function of the read clock skew and as an inverse function of the write clock skew. The write clock skew is measured (410-426,Fig.4) for each memory read and write cycle. The read clock skew (in latch 66) for the first memory read cycle corresponds to the write clock skew (in latch 64) measured at the start of the first read cycle. The read clock skew for the second memory read cycle is obtained by adding to the write clock skew measured at the start of the second read cycle a measured half-line period of the video input signal and taking the fractional part of the sum thereof. The integer part of the sum is detected (68) to initiate the start of the second memory read cycle. The difference (96) between the write skew signal (64) and twice (84) the read skew signal (66) determines the delay imparted to the video signal.

IPC: F02M37/20
Filed: 1986-12-04
Abstract: For pumping liquid fuel substantially free of air from a storage 
tank to a nozzle (68), a vane pump (84) and centrifugal separator (86) 
are used which are bolted together and share a common drive shaft 
(108), whereby fuel is pumped from the vane pump (84) into a central 
portion (103) of the centrifuge (86) in parallel with the longitudinal 
axis of a curved multibladed impeller (Fig. 4) of the centrifuge while 
the impeller is rotating, whereafter the rotating impeller creates 
centrifugal forces to cause air to be extracted from the fuel, the air 
being directed rearwardly along the axis of the impeller for delivery 
to a vent port (118) and the fuel substantially free of air being 
driven against the inside wall of the centrifuge and delivered to a 
fuel outlet port (148). A sump (89) is connected to the vent port 
(118) of the centrifugal separator (86) for receiving a rarefied 
air/fuel mixture therefrom for completing the separation of air from 
the fuel.

Title: An improved patient support structure and a multioutlet variable flow gas valve
IPC: A61G7/057
Filed: 1986-12-16
Abstract: The patient support structure or bed comprises an articulatable frame (30) having a plurality of elongated inflatable sacks (1 to 10) thereon, the sacks being connected to a low pressure compressed air blower (104) and a plurality of pipes (100) for carrying gas from the blower to the sacks. The sacks rest atop a neoprene membrane which covers a planar upper surface (64) of the frame (30). Power to the air blower is supplied by a variable autotransformer adjustable by an electric motor mechanically connected thereto, and operation of the motor is controlled by an electronic circuit which balances the autotransformer voltage against a preset reference voltage. A multi-outlet, variable flow, gas valve comprises a housing (136) defining an inlet (140) and a passageway (138). The valve housing further defines at least two cylinder chambers (142) communicating with the passageway and a discrete outlet (144) for each cylinder chamber, and a piston (146) is substantially nonrotatably disposed inside each cylinder chamber, but is movable along the chamber (142) by a motor (160) to vary flow through the valve and to selected ones of the sacks (70). The sacks can be rapidly deflated via a plurality of solenoid valves, and the pipes from the blower can be directed to different sacks by opening and closing a plurality of manually operated valves.
