Patent EP-0271024-A3 (EP)
IPC: G03F9/00
Filed: 1987-12-04
Abstract: An optical focus sensing system is disclosed. The 
system provides a focus shift measurement capability utilizing 
the relative motion between two gratings to produce different 
diffraction orders which are separately detected by a pair of 
detectors to form signals having a phase difference 
proportional to the focus error corresponding to the planes 
occupied by the two gratings. A control circuit is responsive 
to the phase difference between the signals from the two 
detectors to provide a controllable focusing capability.

Patent EP-0272032-A3 (EP)
IPC: B60T11/228
Filed: 1987-12-08
Abstract: A master cylinder assembly has a plurality of separate 
pressure cylinders (1) between which extends a transfer 
passage (17) controlled by valve means (19) to permit 
communication between respective pressure chambers of 
the cylinders when the cylinders are actuated 
simultaneously for normal retardation and to prevent 
such communication when one of the cylinders is 
operated individually for steering purposes. Pistons 
(3) are movable in the cylinders to pressurise fluid, 
in use, for brake actuation and hold the valve means 
(19) open during part of their travel. A reduced 
diameter rear part of each piston, when opposite the 
valve means, permits closure of the latter in the event 
of pressure failure in one of the cylinders, to enable 
braking pressure to be maintained in the other cylinder.

Title: Ignition system for internal combustion engine
IPC: F02P11/04
Filed: 1988-03-23
Abstract: An ignition system for an internal combustion 
engine comprising a semiconductor power switching device 
(2) which is controlled by a control unit (1) is dis­
closed. In response to an output from a device (5) for 
detecting a shorting breakdown or a heat generation of 
the power switching device (2), the power switching 
device (2) and the ignition coil (3) are separated 
from a power supply (Vg) by a current cut-off device 
(8, 8′). Even when the power switching device (2) 
breaks down by shorting, the power generation due to 
the continuous energization of the ignition coil (3) is 
prevented thereby to prevent the ignition coil (3) from 
being heated abnormally.

Title: Supporting device for positioning reinforcements
IPC: E04C5/18
Filed: 1988-04-21
Abstract: The insert, to be set in concrete, for ensuring the desired position of reinforcements in reinforced concrete building components consists of at least two stirrups, which are open towards the formwork and welded together by means of longitudinal bars to form a unit, and at the stirrup ends of which the internally threaded sleeves are arranged, which are equipped with holding elements for the lower reinforcement, while the upper reinforcement is supported by the stirrup crosspieces or the longitudinal bars. The concrete covering for the upper reinforcement is ensured by the fact that the height of the stirrups is adapted to the desired position of the upper reinforcement. The insert is characterised in that it serves both to ensure the desired position of the reinforcements and, after the concrete has set, permanently, if necessary, as a constructional reinforcement for suspended loads acting on the underside of the building component and/or as a shear reinforcement. <IMAGE>

Patent EP-0295896-A3 (EP)
IPC: H04B3/54
Filed: 1988-06-15
Abstract: An apparatus for controlling the output of a 
switching amplifier (38) includes a signal dividing circuit 
(14) which generates a delayed replica (S1) of the carrier 
signal and a doubled signal (S2) having twice the carrier 
frequency. The doubled signal is effective for establish­
ing a second time delayed signal relative to the first time 
delayed signal (S1A). The first and second time delayed 
signals are logically operated on so that a three state 
output representing the carrier signal is attained. A 
summing amplifier (26) utilizes the two time delayed 
signals to generate this three state output whereby if the 
two time delayed signals are out-of-phase, a zero voltage 
is connected to the drive portion (40, 42) of the switching 
amplifier thereby limiting the output of the switching 
amplifier.

Abstract: A method and apparatus comprising engaging the open 
end of a first plastic parison which is at a temperature within 
its molecular orientation temperature range, enclosing a hot 
mold which is at heat setting temperature about the parison at 
a first position, simultaneously enclosing a cold mold at a 
second position about a container previously blown in the hot 
mold to cool the previously blown container, expanding the 
plastic parison within the hot mold by internal pressurization 
through the open end to induce biaxial orientation of the plastic 
parison and force the plastic parison into intimate contact and 
conformance with the hot mold and to maintain contact by such 
internal pressurization between the mold and biaxially oriented 
container for a time sufficient to induce partial crystallization 
in the biaxially oriented container, moving the hot mold and 
the cold mold in unison to bring the hot mold to the second 
position and the cold mold to a third position during the 
expanding of the parison within the hot mold and during the 
cooling of the previously blown container in the cold mold, 
maintaining a lower internal pressurization of the container 
in the hold mold and exhausting the pressurization to atmospheric 
pressure in the cold mold, substantially simultaneously opening 
the hot mold and cold mold, moving the open hot mold to the 
first position and open cold mold to the second position.

Abstract: A heat-fusible flowable particulate material for 
providing fused polymeric three-dimensional articles 
comprise a predominant component in the form of a 
heat-fusible flowable substantially non-agglomerating 
polymeric powder and at least one secondary component in 
the form of a polymeric powder. The secondary component 
is mixed with said predominant component and is miscible 
or reactive with it to form, when fused, a solution with 
the predominant component at the interface between said 
predominant component and said secondary component. The 
two components form, when fused, domains of each material 
and the interaction takes place at the abutment between 
the domains. The secondary component is in quantities 
such that there is a detectable difference in stiffness 
and/or adhesive capabilities between the predominant 
polymeric component without the secondary polymeric 
component and the predominant polymeric component with 
the secondary polymeric component added.

Abstract: A positive pressure filter respirator includes 
a full face mask comprising an outer mask 1 and an 
inner orinasal mask 2. A filter canister 5 is screw 
mounted to an air inlet 4, and a centrifugal fan 6, 
which is driven by a battery operated motor 7, is 
so arranged as to draw air through the filter canister 
5 into the outer mask 1. The filter life and the 
battery life are extended by the use of a pressure 
responsive means which responds to the difference 
in pressure between the pressure in the interior of 
the orinasal mask 2 and the pressure in the space 
20 within the outer mask 1 and outside the orinasal 
mask 2. The pressure responsive means reacts 
immediately to the commencement of either exhalation 
or inhalation to disable the fan 6 on commencement 
of exhalation and to accelerate the fan 6 on 
commencement of inhalation. The pressure responsive 
means comprises a diaphragm 9 and an infrared proximity 
detector 10 mounted close to the diaphragm 9, and, 
as described, the pressure responsive means acts to 
switch off the fan 6 at the commencement of exhalation 
and to switch the fan 6 on at commencement of 
inhalation.
