Title: Adhesive wound dressing
IPC: A61F13/02
Filed: 1987-04-14
Abstract: A wound dressing comprises an alginate layer fixed to a plastics backing layer, such as a polyurethane film. The backing layer extends beyond the edges of the alginate layer to provide a marginal portion which is coated with adhesive. Such a dressing may be formed by providing an adhesive-coated plastics film having a lamella releasably attached to its adhesive surface, cutting the lamella into an inner and an outer portion, such that the outer portion surrounds the inner portion, removing the inner portion to expose a region of the adhesive-coated plastics film, and attaching the alginate layer to the exposed region of film.

Patent EP-0278400-A3 (EP)
IPC: B29C49/02
Filed: 1988-02-04
Abstract: An apparatus is disclosed that is intended for manufacturing a hollow body. The hollow body has a head piece formed by blow-molding a preform segment. The apparatus includes a ring-shaped nozzle, a withdrawal device, and blow-mold pieces which are laterally, reciprocally movable. Regions of the hollow body are fabricated to have outer diameters which are less than the diameter of the extruded tubular segment before the segment is blow-molded. This is achieved by a reciprocally movable mandrel with a molding extension. The molding extension extends both radially and inwardly between projecting regions of the closed blow-mold pieces. The projecting regions of the blow-mold pieces press the corresponding parts of the preform segment against the molding extension, wherewith the ring-shaped nozzle opening is radially, outwardly offset with respect to the outer contour of the molding extension. Following the extrusion, the molding extension is advanced downward, in the embodiment illustrated, and serves as an implement for forming the inner shape of the reduced-diameter region or regions of the body part, and as an opposing thrust element for the blow-mold pieces which press together a region or regions of the tubular preform segment.

Title: A container and a method as well as an assembly for its manufacture
IPC: B31B29/00
Filed: 1988-03-25
Abstract: In a container (1) of flexible material and including a tube-shaped blank divided into two opposite side walls (5) and two intermediate pairs of gusset walls (6) by means of gussets (2, 3), and having at least one block bottom (8, 9), a tightly sealed, outwardly folding discharge valve (11) is provided in the block bottom (8), said discharge valve being resealable and provided with a gripping means (16). The opening of the valve is formed by shortening a part of the folded end area to predominantly the same length as the depth (19) of the gusset (2). When manufacturing the container (1) from tubing, it is gusseted and divided into blanks corresponding to the container. Then a part of the end area of the blank is cut along a first intersection parallel and adjacent to the middle fold (7) in one of the gussets (2) when the blank is folded up, and along a second, transverse intersection (23) one gusset depth (19) apart from the fold lines (25) around which the final folding of the side walls is performed, whereupon the block bottom (8) is folded, while optionally mutually glueing or welding the folded side walls. Only the parts of the block bottom (8) not in touch with the gusset walls (6) with the cutout are optionally glued or welded. The resulting container with block bottom has a well functioning resealable discharge valve and is suitable for manufacture in a continuous process from an endless material without use of extra material.

Patent EP-0364036-A3 (EP)
Title: Continuously transmitting and receiving radar
IPC: G01S7/35
Filed: 1989-10-09
Abstract: A continuously transmitting and receiving radar comprises a 
transmitter (10), a receiver (16), an antenna (12) and a circulator 
(14) for effecting communication between the transmitter and the 
antenna and between the antenna and the receiver. A reflected power 
canceller is provided for suppressing the effects of leakage 
between the transmitter and receiver. The reflected power 
canceller comprises a directional coupler (20) for supplying a part 
of the transmitted signal to a modulator (22) which forms a 
cancelling signal by adjusting the phase and amplitude of the 
sampled signal. The cancelling signal is applied to another 
directional coupler (24) which subtracts the cancelling signal from 
the leakage and wanted signals. A narrowband control path is 
connected between the output of the receiver (16) and the modulator 
(22). The reduction in carrier leakage and AM noise sidebands is 
made more effective by providing a time delay device (21) in the 
signal path from the coupler (20) to the modulator (22). The time 
delay introduced by the device (21) is set so that the propagation 
times between the transmitter (10) and the directional coupler (24) 
via the circulator (14) and via the modulator (22) are the same. 
Optionally FM noise can be reduced by ensuring the propagation time 
of the local oscillator signal applied to a mixer in the receiver 
(16) is the same as that of the leakage path between the 
transmitter and receiver.  
     In a non-illustrated radar the circulator (14) may be omitted 
and separate transmitting and receiving antennas are provided.

sides of the coin a surface enclosing an angle deviating from 
a right angle with the bearing surface of the middle portion 
on the side of the coin where said part of the border portion 
is situated. These features permit a coin resting on a flat 
surface to be tilted by pressing its border portion, and thus

Patent EP-0357168-A3 (EP)
Title: Method and apparatus for improved preparation of fried foods
IPC: A23L5/10
Filed: 1989-09-01
Abstract: The present invention provides a method and apparatus 
for the preparation of what is commonly known as "fast 
foods" such as french fried potatoes. These foods are 
generally cooked in a vat of heated oil and, as a result of 
such preparation, include a high concentration of polyun­
saturates and cholesterol in levels which may be detrimental 
to the health of the consumer over long periods of time. 
The method of the present invention pre-cooks food in a 
non-fat environment such as a microwave oven. Thereafter, 
the food is transported by a conveyor system through dif­
ferent cooking stations, at least one of which sprays the 
pre-cooked food with closely monitored quantities and 
concentrations of heated oil. The sprayed oil may be mixed 
with water or air and sprayed under pressure at elevated 
temperatures. In this manner, the prepared food has the 
appearance, taste and texture as though it were cooked in 
the traditional way, but is not saturated with oil as it 
would be if it were immersed in a heated vat. In other 
aspects of the invention, the conveyor system may provide an 
 
 
oscillating or lateral movement to the food that it is 
transporting to uniformly distribute the sprayed oil over 
the surface of the food, and to shake excess oil from the 
food. The conveyor system includes a wire mesh food support 
so that the sprayed oil may penetrate the under surface of 
the food and any excess sprayed oil may drip from the 
conveyor system to avoid over-saturation of the sprayed 
food.

wall and the internal part of retention member body; and a cover (c) 
comprising a top cap (26) for covering the exit orifice of the bottle 
which is inserted into said retention member body; the cover 
having, at least a tubular wall (28) coupled to the upper part (26) to 
internally guide it in the retention central wall (16); an annular 
wall (32) attached to the lower end of 
the tubular walls (28), and at least 
one transversal orifice (42) in the 
annular wall (32) to permit the passage 
of the contents of the bottle; second coupling means located on 
the lower part of the annular wall (32) which are interconnected with 
the first coupling means (18) of the retention member body, which, 
when the cover is advanced with an upward movement, the content

is retracting with an upward movement it close the orifices; and, 
a tubular wall (38) located at the lower part of the annular wall, 
having a second retention member (40) within its external periphery, 
which is attached with the first retention member in order to 
prevent that the cap can be removed from the retention member 
body.
