Patent EP-0066465-A3 (EP)
Title: Biopsic forceps
IPC: A61B10/00
Filed: 1982-05-28
Abstract: A biopsic forceps for taking structural specimen within body cavities as inserted into a forceps channel of an endoscope or directly into an incised body cavity. Known biopsy forceps have various formations for taking structures within body cavities. However, in the biopsic forceps of this invention, a pair of resilient holding pieces 23 and 24 separate to form a V are provided at the tip of a shaft 22 slidably inserted through a pipe 21, respective cutting blades 25 and 26 opposed to each other are provided on these holding pieces so that, when the holding pieces project from the pipe, they separate from each other to open the cutting blades and, when the holding pieces are retracted into the pipe they close to mesh the cutting blades with each other. The shaft 22 is supported by one of a pair of handles 31, 32 moving to open and close about an off-set fulcrum 33 as a centre and the pipe 21 is supported by the other handle so as to be moved axially along the shaft so that if the structure of a part to be inspected (affected part) is hard, and strong force needs to be applied to retract the holding pieces into the pipe to mesh the cutting blades, the shaft is not subjected to any unreasonable bending force, and will be enither bent nor broken.

IPC: B65D81/26
Filed: 1982-07-08
Abstract: A pack intended to contain a solid substance such as a 
detergent powder from which liquid has a tendency to bleed 
is constructed to reduce the extent of such bleeding. The 
construction involves the provision on the inside of the pack 
of a surface having an open-pored structure. The open-pored 
structure has been found to reduce capillary attraction of 
liquid for the carton. Open-pored structures can be formed 
using, for example, non-woven fabrics, foamed board or 
sintered materials.

Patent EP-0128427-A3 (EP)
IPC: H01L29/792
Filed: 1984-05-24
Abstract: In a semiconductor memory using a dynamic memory 
device (24), a battery (17a . . . 17c) supplies a power source 
voltage and a substrate bias voltage when the memory is cut 
off from an external device, and a refresh control circuit (22) 
changes the refresh timing of the memory device (24) in 
accordance with the leakage current of the memory device 
(24). The power consumption of the memory can thus be 
reduced and the data can be kept for an extended period 
without an external power source.

recording and reproducing characteristics which are not sub­
jected to the interference actions on the recording and repro­
duction due to the edge portion of the auxiliary pole core.

oxide wherein a mixture of nitrous oxide and a diluent is

Patent EP-0219945-A3 (EP)
IPC: C01B15/037
Filed: 1986-08-26
Abstract: Unless aqueous acidic hydrogen peroxide solutions are 
stabilised, an excessive rate of decomposition of hydrogen 
peroxide precludes their use for treatment of metal surfaces, 
such as of copper and copper alloys, during which use 
substantial concentrations of decomposition catalysts build-­
up in solution. Regular monitoring of the solutions for 
residual stabiliser content would demand sophisticated 
analytical equipment beyond the reach of many users.  
     The invention provides a stabiliser in the form of a 
block of sparingly soluble material, whereby monitoring can 
be simply and readily effected visually or by a simple 
electrical or mechanical detection system. For copper/copper 
alloys preferred stabilisers are p-hydroxybenzoic acid and 
triphenyl carbinol.

IPC: E04C2/292
Filed: 1986-10-16
Abstract: A panel comprising a box-shaped element of metal 
sheet having inwardly bent edges designed to cooperate 
with mating bent edges of a panel cover, the bent edges of 
these two elements acting as fastening means between the 
box and the cover when a material capable of expanding into 
a rigid-type structure has been injected into the panel, 
whereby a one-piece, insulated and hermetically closed 
panel is obtained without the aid of any conventional type of 
fastening means. The panel is mainly intended for use in air 
conditioning and processing plants, especially when highly 
uncontaminated air is required.  
     A method for obtaining a panel according to the inven­
tion comprises the steps of forming a box-shaped element 
provided with particularly profiled edges, forming a cover 
with mating edges, fitting the edges of the cover into the 
edges of the box-shaped element, and injecting in the thus 
formed panel a material capable of foaming "in situ" while 
blowing out the air contained in the panel, upon polymeriza­
tion of the foamable material, the latter forming a permanent 
bond which will hold the two parts of the panel firmly joined 
together hermetically.

Abstract: A microwave ovenable package (10) including a layer 
(18) of material that will convert a portion of the microwave 
energy to heat and a layer (16) of paperboard interposed be­
tween the energy-converting layer and the food in the 
package which is to be cooked and browned. The energy-­
converting layer may be carried on a plastic film (20), the 
latter being adhered to the side of the paperboard layer which 
does not contact the food. An additional layer of paperboard 
(26) may be used to sandwich the energy-converting layer 
and the plastic film between layers of paperboard. The heat 
from the energy-converting layer provides a surface heating 
effect on the food such as browning, crisping, or singeing. 
The presence of the paperboard layer between the energy-­
converting layer and the food prevents contamination of the 
food which might otherwise occur due to the degredation of 
the plastic in those cases where the microwave cooking 
causes the energy-converting layer to reach a temperature 
higher than intended.
