Title: Tubular reaction system for a tubular cracking furnace
IPC: B01J8/06
Filed: 1985-07-05
Abstract: A reaction tube system of a steam reformer, more generally referred to as tubular cracking furnace, for the indirect heating of cracking feedstock, such as the catalytic cracking of hydrocarbons, includes a plurality of reaction tubes and headers, the reaction tubes penetrating through the bottom of the steam reformer and being extended to the associated header by low-alloy tube sections attached to the tubes by circumferential welds. The reaction tubes are surrounded in the area of the weld(s) by a coaxial protective tube having one open end and defining a free annular space around the reaction tube. The protective tube prevents deterioration by corrosion of the weld(s) joining the tube sections of high-alloy steel with low-alloy extension sections with unalloyed steel extension section.

IPC: B29C48/06
Filed: 1985-09-06
Abstract: This invention relates to extruder arrangements of the type 
used in extruding elements such as tube-shaped pipes of 
circular or profiled cross sectional configuration or other 
profile products from an extrudable melt such as, for example, 
polymeric material, e.g. unplasticised polyvinylchloride.  
     According to the invention an extruder arrangement comprising 
[a] an annular die having a bore which constitutes a forming 
surface, [b] a mandrel disposed in the die and presenting a 
forming surface facing the forming surface of the die and 
spaced therefrom such that an extrusion passage is defined 
between the two forming surfaces, and [c] a heating arrangement 
in heat conductive relationship with one of the forming surfacen 
is characterised in that it includes temperature differential 
means in heat conductive relationship with at least one of 
the forming surfaces, which temperature differential means is 
adapted in use to allow the temperature of selected circum­
ferential zones of an extrusion piece disposed in the extrusion 
passage to be individually controlled.

Patent EP-0208492-A3 (EP)
IPC: H05K13/04
Filed: 1986-06-30
Abstract: A method of assembling a surface-mounted component 
(5) onto a substrate, comprising applying a deposit of solder 
cream to the substrate, preheating to boil off volatile material 
from the solder cream, and securing the component (5) by 
adhesive to the substrate prior to a reflow stage to solder the 
component (5) to the substrate, wherein the component (5) is 
supplied as part of a stream of such components by a carrying 
medium (2, 10), in which the adhesive is applied to the compo­
nent (5) through cut-outs (7) immediately prior to its location 
on the substrate. The application of the adhesive to the com­
ponent, rather than to the board, cuts out a step in the pro­
Cessing of the substrate. The carrying medium may be a com­
posite paper tape consisting of three layers (1,2,3), a flexible 
multiple blister pack consisting of two layers (1, 10), each of 
which has multiple cut-outs (7), or a magazine having a single 
cut-out. When the components (5) are placed on the printed 
circuit board in their assigned position the adhesive achieves 
a secure mechanical bond between the board and the com­
ponents thus preventing the components from moving, lifting 
or being blown off during the course of the reflow operation 
when components are fused by molten solder to the printed 
circuit board.

Abstract: A probe (20) for longitudinally traversing and 
circumferentially inspecting the interior of a tube. A 
rotating sensor containing head (44) is driven by a rotor (40) 
extending from the end (38) of a cylindrical housing (12) in 
which it is mounted. The axially fixed rotor (40) surrounds 
and is driven by a helix drive connection (70) to a piston 
extension (36). The piston (20) reciprocates in a cylindrical 
chamber (14) within the housing (12) in response to selectively 
applied fluid pressure acting against a spring bias (60). A 
strain gage (62) on the spring (60) controls the fluid 
pressure by means of valve (2) whereby reciprocation of the 
piston (20) and its extension (32) rotates the rotor (40) by 
means of the helical groove (72) and balls (74). The various 
parts are hollow to accommodate the necessary wire conductors 
(51 and 64) and H₂O.

IPC: G01S15/89
Filed: 1987-02-06
Abstract: An ultrasonic transducer probe (200) having a mechanically 
steerable acoustic element (230) includes a linear motor having a 
stationary magnet assembly (202) and a coil (206) bidirectionally linearly 
movable with respect to the magnet assembly. A mechanical 
arrangement formed of a pair of spaced apart, rotatably mounted 
pulleys (222, 224) and flexible belt (210) connecting the pulleys couples the 
coil and the ultrasonic transducer or acoustic element (230). The 
transducer element is mounted for rotation with at least one of 
the pulleys so that linear motion of the motor coil is converted 
to rotative motion of the transducer whereby the transducer and 
the ultrasonic beam (234) it emits is caused to sweep through a 
selected angular sector (10). A position sensor formed of a 
supplemental stationary magnetic material (216) and a position coil (220) 
mounted for movement with the motor coil is utilized for 
detecting the linear position of the coil and, correspondingly, 
the angular orientation or position of the transducer element. 
The pulley (250) carrying the transducer may have a non-circular periphery.

Title: Pipette tip pickup apparatus
IPC: B01L3/02
Filed: 1989-04-11
Abstract: In a liquid handling station taking up and dispensing liquid 
through one or a plurality of pipettes each having a syringe 
and a respective nozzle, it is customary to fit the 
nozzle(s) with a disposable pipette tip(s) which is replaced 
between samples to avoid cross-contamination. There are 
difficulties in reliably fitting and sealing these pipette 
tips onto the nozzles. The present invention simplifies 
the fitting and sealing of pipette tips onto nozzles by 
forming each nozzle with an annular groove having a 
controllably variable axial width. An elastomeric O-ring 
seal is fitted in each annular groove. The nozzle and its 
fitted O-ring seal is inserted into a pipette tip, and then 
the axial width of the annular groove is controllably 
reduced to cause a circumferential expansion of the O-ring 
seal. The nozzle and the pipette tip become mechanically 
and sealingly attached without the pipette tip having to be 
force-fitted onto the nozzle as was previously necessary. 
The pipette tip is subsequently detached by controllably 
increasing the axial width of the annular groove to allow a 
circumferential contraction of the O-ring seal. 
Manufacturing tolerances in the pipette tips do not have an 
adverse effect on the resultant nozzle/tip seal.
