Patent EP-0267575-A3 (EP)
IPC: B22D41/42
Filed: 1987-11-10
Abstract: The unplugging apparatus includes a conduit which 
extends through the wall of an annular member to a gener­
ally cylindrical lance housing disposed within the annu­
lar member. The upper end of the lance (41) housing is dis­
posed above and proximate the elevation of the conduit (43). 
A bushing is disposed within the housing at its upper end 
and guides upward movement of a tube (47) which is partially 
disposed within the housing. The tube carries a charge 
of combustible material and has an upper end disposed 
outside the housing and a bottom flared portion disposed 
within the housing. The bushing defines a stop surface 
for the bottom flared portion of the tube. A combustible 
collar (75) is mounted on the tube upper end and surrounds a 
portion of the charge of combustible material which ex­
tends past the tube upper end.

Title: Drive/frame assembly for a reciprocating floor drive/frame assembly for a reciprocating floor
IPC: F15B15/20
Filed: 1987-07-03
Abstract: Piston rods (60, 62) of three linear hydraulic motors (36, 38, 40) are connected at their outer ends (64, 68) to two spaced apart transverse frame members (10, 12). A cylinder housing (72) is driven back and forth along each pair of piston rods (60, 62). Three transverse drive beams (48, 50, 52) are provided. Each drive beam (48, 50, 52) is directly connected to an associated one of the cylinder housings (72). Three sets of floor slat members (1, 2, 3) are provided. Each set (1, 2, 3) is connected to an associated one of the transverse drive beams (48, 50, 52). The linear hydraulic motors (36, 38, 40) are operated for moving the floor slat members (1, 2, 3) in one direction, for advancing a load, and for retracting them in the opposite direction. Each cylinder housing (72) has four fluid chambers (82, 84, 86, 88). The first and third chambers (82, 86) are interconnected and the second and fourth chambers (84, 88) are interconnected. This arrangement provides adequate force producting area with a relatively small diameter cylinder housing (72). Fluid passageways (110, 112) are formed in the piston rods (60. 62). Transfer valves (138, 140) and U-shaped tubes (134, 136, 126, 128) are clamped onto the outer end portions of the piston rods (60, 62) by means of a pair of clamp plates (190, 192, 214, 224) and interconnecting nut and bolt assemblies (194, 226). <IMAGE>

Patent EP-0241124-A3 (EP)
IPC: G06F12/06
Filed: 1987-03-02
Abstract: A storage device capable of being configured either 
as a single-access memory or as two separate memories is 
described. The storage device is especially suited for 
use in a digital signal processor performing numeric 
algorithms such as fast fourier transforms, 
autocorrelation and digital filtering because certain of 
such algorithms require fast dual access to two 
correlated, but separate, parameters while other such 
algorithms require fast single access to identical 
parameters. The storage device is shown in an exemplary 
embodiment employing a multiplexer to affect writing of 
data from either of two data busses to one of the 
memories. In a second embodiment the write port of 
the memory is connected to one bus and the read port is 
connected to both busses. In this embodiment a 
dual-port address register file and a pair of address 
generation units provide indirect addressing capability 
for the storage device. Method of operating separate 
memories in a single-access or a dual-access mode is 
also described.

Patent EP-0252680-A3 (EP)
IPC: H04M1/2745
Filed: 1987-07-01
Abstract: An automatic dialing apparatus (10) comprises a numeral 
entry device (47) for inputting numerals and a memory (22) for 
storing telephone directory numbers of authorized subscribers 
and their abbreviated dialing numbers in locations addressable 
as a function of the input numerals. For originating a 
call, the input numerals are used as an address pointer of 
the memory. An addressed telephone number is sent to a 
telephone switching system to allow a switched connection to 
be established to a called party and an addressed 
abbreviated dialing number is subsequently sent through the 
connection to the called party. On termination of the call 
to the called party, a coincidence is detected between the 
received abbreviated dialing number and an abbreviated 
dialing number assigned to the called party to verify 
authorization on detection of the coincidence. The latter 
is sent to the calling party to permit it to detect a 
coincidence between it and a copy of the number sent to the 
called party to verify authorization on detection of the 
last-mentioned coincidence.

Title: Process for hardening moulding sand articles
IPC: B22C9/12
Filed: 1988-09-24
Abstract: A process is described for curing sand moldings, in particular casting cores, by the cold box process. In this process a catalyst containing gas mixture escaping from the mold is passed over a mixture feed side of a semipermeable membrane while a pressure is maintained on the permeate side of the membrane which is less than the pressure on the mixture feed side, whereby the catalyst vapors preferentially permeate through the membrane, and a permeate carrier gas stream which is, in particular, 50 to 300 liters greater than the permeate stream passing through the membrane per m2 and per hour is passed over the permeate side of the membrane. The catalyst, in particular a tertiary amine, is greatly concentrated in the permeate carrier gas stream and can simply and inexpensively be removed from the latter by condensation. Inexpensive, virtually complete recovery of the expensive catalyst is possible using the process.
