Patent EP-0274743-A3 (EP)
IPC: C07C69/96
Filed: 1987-12-28
Abstract: Aqueous bischloroformates are prepared by the 
reaction of a dihydroxyaromatic compound (e.g., bisphenol A) 
with phosgene in a substantially inert organic liquid (e.g., 
methylene chloride) and in the presence of an aqueous alkali 
metal or alkaline earth metal base, at a pH below about 8. 
After all solid dihydroxyaromatic compound has been con­
sumed, the pH is raised to a value in che range of about 
7-12, preferably 9-11, and maintained in said range until a 
major proportion of the unreacted phosgene has been hydro­
lyzed. At the same time, any monochloroformate in the 
product may be converted to bischloroformate.
Patent EP-0257674-A3 (EP)
IPC: B21D28/34
Filed: 1987-07-23
Abstract: A punching or stamping machine for operating on thin 
material with very high precision comprises a horizontally 
disposed, elongate fixed base (1) and a hollow movable arm (2) 
extending parallel to the base and connected to it at one end by 
a resiliently flexible web (3). At the other end, on machined 
faces (8 and 9), the arm and the base each carry a set of tools, 
for example, a set of punches and a corresponding set of dies. 
The web (3) forms a connection between the arm and the base which 
will permit the necessary operative movement of the arm in the 
vertical direction but will not allow significant displacement of 
the arm relative to the base in a horizontal direction, thus 
contributing to a maintenance in the accuracy of alignment of the 
punches and dies which is better than that available with a 
pivotal connection, which is subject to frictional wear. A 
further contribution is made by interconnecting the base and the 
arm with flexible elements of a material of good thermal 
conductivity, for example, braided copper strips (25), in order 
to permit a ready transfer of heat between the base and the arm 
so that a thermal balance is maintained between them which 
inhibits differential thermal expansion or contraction of the 
base and the arm. Such differential expansion or contraction can 
result in a movement of the arm relative to the base which can 
affect the alignment of the punches and the dies. In order to 
obtain a quicker heat transfer between the arm and the base the 
arm is preferably lined with copper strips (33) which have 
heat-conducting connection with the flexible connecting strips 
(25)  via  copper rivets (31).

IPC: B01D59/28
Filed: 1987-02-04
Abstract: A method of isotope enrichment including providing a 
reactant. The reactant is a mixture of at least two isotopic 
compounds. One of the isotopic compounds has a greater 
percentage of a selected isotope than the other. An electron 
transfer agent is introduced into the reactant isotope mixture 
to form a reaction mixture. The electron transfer agent 
facilitates transfer of electrons interactive with one or more 
selected nuclei of the reactant. The electron transfer agent is 
in an amount sufficient upon reaction of the reaction mixture 
to establish an equilibrium between an electron rich reaction 
product and an electron poor reaction product. The reaction 
mixture is reacted until the equilibrium is established. The 
electron poor reaction product is then separated from the 
electron rich reaction product.

Patent EP-0250075-A3 (EP)
IPC: H04Q11/04
Filed: 1987-04-29
Abstract: In an integrated services digital network (ISDN) a telephone 
subscriber is physically connected to a telephone exchange by a 
digital signal subscriber loop which provides in time division 
multiplex (TDM), two B channels and a D channel. The two B 
channels are used for voice and data at a bit rate of sixty-four 
kilobits per second each. The D channel is used for packet data 
and for telephone signalling and supervision at a bit rate of 
sixteen kilobits per second. An ISDN D channel handler, in an 
exchange termination (ET) collects D channel data from and 
distributes D channel data to various ISDN subscriber lines. A 
frame processor, in the D channel handler, receives D channel 
information as it occurs in each of the receive channels. It directs 
D channel data to a receive buffer storage location where it is 
accessible by a translator. The translator recognizes information 
in the data which relates to supervisory and signalling functions, 
and passes the information to a central controller in the ET. 
Likewise, signaling and supervisory information destined for an 
ISDN subscriber line is translated into ISDN compatible data 
which is stored in transmit buffer storage locations. The frame 
processor subsequently pulls this data from the storage loca­
tions, and formats it according to CCITT standard, before trans­
mitting it on the appropriate transmit D channel of the TDM bit 
stream to the subscriber. Packet data received in the D channel is 
recognized after is has been stored in the receive buffer storage 
location and then is immediately queued for transmission via the 
frame processor and a digital transmission liink to a separate 
packet network. Packet data from the separate packet network is 
received from the digital transmission link and stored via the 
frame processor in buffer storage locations. Subsequently, the 
information bits of each stored data packet are formatted accord­
ing to the CCITT standard by the frame processor, and transmit­
ted to the intended subscriber on the appropriate D channel.

Abstract: A constant force, self-adjusting, cable control 
device (Figure 1) comprises a first member 10 and a 
second member 11 pivoted together at a pivot point 12, a 
constant diameter coil tension spring 17 arranged to 
bias the first and second members rotationally together, 
cables 13, 15 respectively attached to the first and 
second members and a one-way ratchet latch 23, 24 which 
automatically releases when there is slack in the cables 
to permit relative rotation between the first and second 
members by the effect of the spring 17 until the tension 
on the cables is re-established. The cable attachment 
means 14, 15 are positioned radially outwardly and 
displaced angularly of the spring connections 19, 21 
relative to the pivot point 12 so that the spring 17, 
with a shorter lever arm, has a mechanical disadvantage 
over the cables 13, 15, which decreases as the members 
rotate towards each other.
