Title: Method for packing small objects and package for small objects
IPC: B65B55/20
Filed: 1987-08-04
Abstract: A method of packing small components, in which at least one small component (9) is packed by means of a packing body (1) having a multilayer construction and comprising a non-deformable base plate (3) and a thermoplastically deformable elastic carrier layer (5) fixedly connected to the base plate, the small component (9) being depressed into the heated carrier layer (5) thereby forming a nest by thermoplastic deformation of the carrier layer.
Patent EP-0261983-A3 (EP)
IPC: H01Q25/00
Filed: 1987-09-25
Abstract: A reconfigurable beam-forming network for use 
with a transmitter has a waveguide R-switch that is 
interconnected with a Magic T. The R-switch contains 
phasing elements and is connected to a dual-mode power-­
dividing network, which in turn is connected to first, 
second and third region power-dividing networks, each 
having their own feed horn array. The R-switch can be 
moved to three different positions so that in a first 
position power is divided between two input ports of 
the dual-mode network on substantially a fifty-fifty 
basis with the power on the two input ports being out 
of phase on a positive basis. In a second position of 
the R-switch, power is also divided on substantially a 
fifty-fifty basis between the two input ports but the 
power is out of phase between the two ports on a 
negative basis. In a third position of the R-switch, 
substantially all of the power entering the R-switch is 
passed into the first input port of the dual-mode 
network. The power being fed to the feed horns of any 
one of the regions has the same phase. In a variation 
of the invention, the R-switch and Magic T are replaced 
by a variable phase shifter and Magic T.

Title: Apparatus and method for mass transfer involving biological/pharmaceutical media
IPC: C12N5/02
Filed: 1987-11-26
Abstract: A mass transfer apparatus and method is based upon use of a mass transfer chamber (12), such as a hollow fiber membrane bioreactor, with means to change the directional flow (16) therethrough for enhancement of the mass transfer operation. The invention has particular utility in cell growth systems, where the periodic reversal of flow direction of a nutrient stream passed through the bioreactor equalizes dispersion of cell growth through the bioreactor and enhances the transport of metabolic waste from the cells being grown.
Patent EP-0310835-A3 (EP)
Title: Process for preparing poly(vinylbenzyl ethers) of polyphenols
IPC: C07C41/34
Filed: 1988-09-15
Abstract: Poly(vinylbenzyl ethers) of polyphenols are prepared by reacting an alkali metal, alkaline earth metal, or ammonium salt of a polyphenol with a vinylbenzyl halide in a liquid reaction medium consisting essentially of a monohydric alcohol or glycol having from 1 to 11 carbon atoms, a polyglycol having a weight average molecular weight ranging from 200 to 4000, or glycerol. Halide ion content of poly(vinylbenzyl ethers) of polyphenols prepared by the method of this invention and other methods are reduced by dissolving the ether in a solvent that dissolves no more than 1.0 weight percent of an alkali metal, alkaline earth metal, or ammonium halide; separating the ether solution from the halide salt; and then recovering the ether from the solution.

Title: Rotatable antenna with a bearing and a counterweight
IPC: H01Q3/08
Filed: 1989-05-13
Abstract: The bearing of a rotatable antenna, particularly a rod or telescopic antenna, should also provide the possibility of connection between antenna and antenna feedline with reliable contact during the rotation of the antenna. If DC-isolation between antenna and the line for supplying power to the set is additionally required for safety reasons, this requirement can only be met with difficulty with discrete components, for example capacitors, waveguides and so forth at high frequencies without a mismatch occurring between antenna and device. To produce matching and to meet the safety requirement, the bearing is constructed in the form of a capacitive rotary coupling matching the antenna impedance and impedance of the antenna feedline. In addition, the antenna rod length can be largely freely selected by dimensioning the individual components of the rotary coupling and by dimensioning the counterweight. The rotatable antenna is preferably used in the base station of a cordless telephone. <IMAGE>

Patent EP-0398495-A3 (EP)
IPC: G06F12/00
Filed: 1990-04-10
Abstract: A distributed data processing system and method in which locks on a 
file are supported by a data structure that resides on either a client 
machine or on the file's server. When only a single client's processes 
are locking a file, the data structure can reside on that client. 
Whenever a plurality of client machines attempt to place locks on a 
file, the data structure is moved to the server; this forces the 
clients locking the file to communicate with the server when performing 
lock operations. When a client requests a lock from the server that 
cannot be granted because of an existing blocking lock, the client is 
informed that it should put the requesting process asleep awaiting a 
retry notification. When there is a change in the locks on the file 
that might allow such a client's now sleeping process to acquire the 
lock, the server sends a retry notice to the client. This awakens the 
sleeping process at the client, and the process then reattempts the 
lock operation by sending a message to the server.

Title: Method and apparatus for sputter coating stepped wafers - case a
IPC: C23C14/34
Filed: 1990-04-12
Abstract: A magnetron sputtering method and apparatus employing an 
annular target comprising a single unitary block the thickness of 
which is varied to provide for a non-uniform removal of material 
during the sputtering process and having a concave continuously 
smooth surface with an inwardly facing portion close to and surround­
ing the outer edge of a stepped wafer. Thus the block provides 
a sputtering surface with areas facing differently facing surfaces 
of the wafer steps. Two concentric erosion zones on the target 
surface are independently energized at different electrical 
parameter values by synchronizing the power applied to the single 
target with switched activation of plasmas overlying the respec­
tive target regions which define the erosion zones. The electrical 
parameters and the geometry are established so as to uniformly 
coat the differently facing surfaces of the stepped wafer. During 
part of the duty cycle during which each target region is energized, 
parameters are measured. Such parameters may be those which vary 
with changes in geometry as for example may be due to target 
erosion. The operation of different target regions, such as the 
duty cycles or power levels for such regions, is separately varied 
in response to the measurements or otherwise, to maintain uniform 
substrate coating as the target erodes. The target has an annular 
pole piece embedded to reduce the space separating the target 
erosion regions, and includes means to cool the target and reinforce 
it against thermal expansion.

Filed: 1990-06-06
Abstract: The speed of rotation of a side wall roughing 
tool (250) can be varied in accordance with the speed of

(CV1, CV2), the arrangement being such that, with the 
rate of flow through each such valve set, the operator 
can select one or other to be switched into the hydraulic 
circuit by which a hydraulic motor (232) is driven, said 
motor effecting rotation of the tool. The selection of 
one or other flow control valve (CV1, CV2) is made by the 
operator during the digitising of the path of the tool 
relative to the shoe and such information is stored 
together with the programmed instruction, in the form of 
digitised coordinate axis values, for said path.

Abstract: A multiple beam space antenna system for facilitating communications between a satellite switch (100) and a plurality of earth-based stations (1,a,b,) is shown. The antenna is deployed after the satellite is in orbit by inflation of a raft-type supporting structure which contains a number of antenna horns (80). These antenna horns are oriented in substantially concentric circular groups (A-D) about a centrally located antenna horn (80). Each of the antenna beams projects an area on the earth. Each of the areas (a,b) of the beams are contiguous. As a result, one large area is subdivided into many smaller areas to facilitate communications. In addition, a lens (FIG. 7C and 7D) may be employed to focus the beams of the horn antennas.
