Title: Superconducting materials and methods of manufacturing the same
IPC: C01G1/00
Filed: 1988-03-28
Abstract: A high Tc superconducting ceramic material of the 
general formula (A 1-x B x ) y Cu z O w  where A represents a 
rare earth element and B represents one or more 
alkaline earth metals for example is manufactured by a 
process designed to limit significantly the presence 
of alkali metal impurities such as lithium, sodium and 
potassium in the final material. Very high purity raw 
materials are utilized and are washed in very high 
purity water in order to wash out any soluble alkali 
metal impurities. Carbon and nitrogen impurities are 
also minimized as too are halogen impurities. 
Superconducting materials having a Tc and Tco in 
excess of 100°K are obtained.
Patent EP-0309192-A3 (EP)
Title: Control for electronic lock
IPC: E05B49/00
Filed: 1988-09-20
Abstract: A battery powered (40) electronic locking 
apparatus comprises a locking member (2) movable between a 
locking position and an unlocking position, a first 
electromechanical means (110) coupled to the locking member 
to drive the locking member from one of the positions to 
the other position upon activation of the first 
electromechanical means and a second electromechanical 
means (111) coupled to the locking member to drive the 
locking member from the one position to the other position 
upon activation of the second electromechanical means. A 
control means (3) activates the first electromechanical 
means (110) without the second electromechanical means 
(111) to attempt to drive the locking member from the one 
position to the other position to conserve power, and 
subsequently activates the first (110) and second (111) 
electromechanical means together to attempt to drive the 
locking mechanism (2) to the other position. This provides 
movement of the locking member (2) when the battery voltage 
is low or the locking member is bound. In addition, if one 
attempt by one (110) or both (110, 111) electromechanical 
means is unsuccessful, the control means (3) automatically 
activates (254, 256, 258) one or both of the 
electromechanical means a second time. This is effective 
in the event that the failure was due to torque applied by 
a user to a door handle which bound the locking member.

Patent EP-0346873-A3 (EP)
Title: Flash thermal transfer method and flash thermal transfer apparatus for practicing the method
IPC: B41M5/382
Filed: 1989-06-14
Abstract: An image formed by an arbitrary method, can be 
reproduced on an object (to which image transfer is 
performed) having a three-dimensional arcuated surface, 
e.g., a cylindrical object. An original plate sheet 
(19) is prepared by forming an image on a transparent 
sheet by using an ink containing carbon. A transfer ink 
sheet (18) having a hot-melt ink layer (18c) formed on 
its one surface and a reflecting layer (18b) formed on 
its other surface is placed on an object (28) to which 
image transfer is performed. A cushion member (17a) 
having transparency is placed on the transfer ink sheet 
(18), and a transparent plate (17) is stacked on the 
cushion member (17a). When the transparent plate is 
urged against the object side, the cushion member (17a) 
is compressed. As a result, the original plate sheet 
(19) is deformed along the outer surface shape of the 
object (28) and is brought into tight contact therewith. 
A flash lamp (13) is turned on in this state. An image 
portion absorbs infrared rays emitted from the flash 
lamp (13) and generates heat. Light radiated on 
portions other than the image portion is reflected by 
the reflecting layer (18b). For this reason, only a 
portion of the hot-melt ink layer corresponding to the 
image portion is melted and is transferred onto the 
object (28). The image on the original plate sheet (19) 
can be also formed in this manner.

Title: Method and apparatus for making an optical fibre member
IPC: B29C48/05
Filed: 1989-04-21
Abstract: A method is described of making an optical fibre 
member, in which foamed or foamable material (5) is 
introduced into an annular region surrounding a 
travelling optical fibre (1) to form a foamed sheath 
which surrounds the optical fibre and is spaced 
therefrom. The sheath (6) travels in the same 
direction of travel as the optical fibre (1) but, over 
an initial portion of its travel, at a speed less than 
the speed of travel of the optical fibre. A drawing 
force is applied to tha sheath so that the sheath and 
the optical fibre subsequently travel at the same speed 
and the internal diameter of the sheath is thereby 
caused to approach the external diameter of the optical 
fibre.
