Patent EP-0207812-A3 (EP)
Title: Method and apparatus for the manufacture of composite articles, and articles made thereby
IPC: B29C69/00
Filed: 1986-07-07
Abstract: A plastics pipe or pipe coupling is made by injection moulding the plastics pipe or coupling body 1, injection moulding at least one sealing ring 3 separately but susbstantially simultaneously, and bringing the body and sealing ring together directly after the moulding while these components are still in a hot as-moulded state, so that a direct thermal bond is formed between them. Preferably, the respective moulds are opened but the components are not stripped but are brought together for bonding while still in position on respective mould members 15, 19. This eliminates intermediate handling and ensures that the moulded components remain clean and of accurate shape and dimension as they are brought together. Moulding apparatus comprises respective injection moulding cavities for the body and sealing ring, and a reversible support for carrying the sealing ring out of its mould and into contact with the moulded body.

IPC: G06F9/26
Filed: 1986-08-14
Abstract: A self-contained user-defined control store is tightly-cou­
pled to a reduced instruction-set processor chip. Special access 
is provided without off-chip handshaking protocol, acknowledge­
ment or the use of additional circuitry, so that the control store 
coexists with a main instruction memory through the use of a 
separate address space. The external control store is preferably 
a programmable read only memory (PROM) in which a single 
enable signal initiates access to the PROM. A ROM 'configura­
tion' register within the RISC processor can be set by the user to 
indicate the ROM access time and a status register contains a bit 
position which indicates whether instructions are to be fetched 
from the normal instruction memory or from the external control 
store. The external control store can be used for certain com­
monly-occurring procedures such as powe-on and system 
routines, diagnostics, interrupt- and trap-handling, hardware 
memory management and macros. In an illustrative application 
implementing trap-handling, the RISC processor recognizes a 
smet of 'trapped' instructions. The self-contained external control 
store of the instant invention is directly connectable to a RISC 
processor of instant invention without additional circuitry or 
complicated inter-chip communication protocols.

Patent EP-0321807-A3 (EP)
Title: Process for recycling waste materials
IPC: C10G1/00
Filed: 1988-12-10
Abstract: A liquid fraction and a gas fraction produced during the reprocessing of waste material containing CH compounds by pyrolysis, have a mass ratio approximately equal to 1. Since the liquid fraction is more suitable for further processing than the gas fraction, there is an incentive to augment the liquid fraction at the expense of the gas fraction. In order to achieve this object, the pyrolysis gas is cooled until the benzene and the higher-boiling gaseous constituents of the pyrolysis gas pass into the liquid phase, so that a benzene-containing liquid fraction is produced. A gas mixture containing benzene and toluene is stripped out of the benzene-containing liquid fraction, passed together with the gas fraction at a temperature of 300 DEG  to 450 DEG  C. over a zeolitic catalyst and then separated by cooling into both a fraction which is liquid at atmospheric pressure and a residual gas fraction. As a result, the proportion of the liquid fraction is substantially increased and the economics of the process are substantially improved.

The screw is tightened by the wedge collet so as to engage and clamp a workpiece. The clamping block, the clamping pieces, and the end block have clamping surfaces extending on both sides in the axial direction, so that the chucking unit may also be secured by clamping shackles acting on the clamping surfaces, with the aid of clamping elements and the T blocks sliding in the grooves of the table.
Patent EP-0301695-A3 (EP)
Title: Data processing system
IPC: G06F15/16
Filed: 1988-06-20
Abstract: A data processing system is described in which 
the workload is divided into packets. A plurality of 
processors access the packets and process them by 
rewriting them according to predetermined rules. Packets 
can be of a number of different types, including XAPP and 
PAPP. An XAPP packet contains a function and one or more 
arguments in evaluated form, so that the function can be 
immediately applied to the arguments. A PAPP packet is 
similar except that its arguments may not be in evaluated 
form. Processing of an active PAPP packet consists of 
activating other packets which evaluate the arguments of 
the PAPP packet, and converting the PAPP to a suspended 
XAPP packet, awaiting return information from those other 
packets. The use of different packet types allows 
greater efficiency, by eliminating redundant actions in 
processing of the packets.

Title: Temperature compensated bipolar circuits
Inventor: JOHNSON TERRY J
IPC: H01L27/06
Filed: 1989-07-14
Abstract: A temperature compensated ECL gate (20) with each 
gate circuit resistance formed by a pair of opposite 
polarity temperature coefficient resistors. A first gate 
transistor element (Q1) and a second gate transistor 
element (Q2) coupled at a common emitter coupling (12) 
provide alternative collector current paths from high 
potential (V CC ) through a first gate transistor collector 
path with collector resistance (R11,R12) and a gate 
transistor collector path with collector resistance 
(R21,R22). A current source transistor element (Q3) is 
coupled between the common emitter coupling (12) of the 
gate transistor elements and low potential (V EE ) through 
current source resistance (R31,R32). The resistances of 
the ECL gate each include a positive temperature 
coefficient silicon first resistor (R11,R21,R31) and a 
negative temperature coefficient low capacitance 
polysilicon second resistor coupled (R12,R22,R32) in 
series. The sum of the resistances of the first and second 
resistors is selected to providing the respective circuit 
resistance of the ECL gate and the ratio of the resistances 
of the first and second resistors is selected according to 
the temperature characteristics of the current source 
voltage generator and the temperature characteristics of 
the first and second resistors for substantial temperature 
compensation of the gate current and signal voltage swing 
over a specified temperature range. The temperature 
compensating pair of opposite polarity temperature 
coefficient resistors is also applicable for temperature 
compensation at active nodes of TTL and STL circuits.
