Patent EP-0329630-A3 (EP)
IPC: H05K13/04
Filed: 1989-02-07
Abstract: The invention relates to a placement head assembly (100) 
for use in an electrical component placement machine and to a 
method of placing components on a circuit board. A hollow 
main shaft (34) has a carriage assembly (124, 126) disposed 
thereabouts. Rollers (144, 146, 148, 150) on the carriage 
assembly engage the shaft outer surface (34), providing for 
axial movement along the shaft. A vacuum support shaft (106) 
in coaxial alignment within the main shaft telescopes down­
wards to pickup and retain a component for subsequent align­
ment in a plane substantially normal to the longitudinal shaft 
axis.  
     The carriage assembly carries actuator means (152, 154, 
156, 158, 136, 160, 162) urging the carriage assembly into 
axial movement in response to fluid pressure differentials. 
Tweezer means are pendantly disposed in quadrature from pivot 
points about the shaft. Jaws at the lower ends of the tweezer 
means are thereby positioned circumferentially about the 
component when suspended from the vacuum support.  
     Downward movement of the carriage assembly causes roller 
surfaces thereon to engage corresponding surfaces of upper 
ends of the tweezer means, thereby forcing these upper ends 
radially outwards. Pivoting action of the tweezer means 
correspondingly forces the jaws radially inwards from four 
quadrants into contact with the component, thereby aligning it 
for subsequent board placement.  
     In one embodiment, the actuator means includes a piston-­
cylinder assembly. Pressure differential across the piston 
causes downward movement of the carriage assembly. Reverse 
pressure differential urges the carriage assembly upward. 
Spring-loaded return of the jaws to the radially outwards 
position prior to contact with the component is thereby 
facilitated.

Title: Thermal ink jet device

Filed: 1990-03-07
Abstract: A thermal ink jet printhead (Figs 1 and 2) has heating element structures (18) which 
space the portion (33) of the heating element structures subjected to the cavitational forces 
produced by the generation and collapsing of the droplet expelling bubbles (26) from the

to be produced so that a lower temperature section (34) is located between the bubble 
generating region (33) and the electrode connecting point (36). In another embodiment (Fig. 5), 
the electrode (17) is attached to the bubble generating resistive layer (31) through a doped 
polysilicon descender (38). A third embodiment (Fig. 6) spaces the bubble generating portion (54) 
of the heating element from the upstream electrode interface, which is most susceptible to 
cavitational damage, by using a resistive layer (52,54) having two different resistivities.

Title: Novel polyacetal terpolymers of trioxane and alpha, alpha-and alpha, beta-isomers of glycerol formal and functional derivatives thereof
IPC: C08G2/20
Filed: 1990-05-10
Abstract: Cationic polymerization of trioxane and a 
mixture of α,α- and α,β-isomers of glycerol formal 
(or their ester derivatives) yields acetal 
terpolymers having pendant functional groups (i.e., 
hydroxyl or ester groups pendent from the polymer's 
backbone). The glycerol formal monomers employed in 
this invention may include functional groups 
selected from hydroxyl or ester moieties which are 
protected from, and thus survive, the polymerization 
process with trioxane. These groups may then be 
present as functional reactive sites for the 
subsequent synthesis of block polymers and/or to 
chemically bind modifiers to the acetal terpolymer 
backbone, for example.

Title: Processing apparatus with wall conditioning shuttle.
Inventor: BENSON ROBERT ARTHUR
IPC: B01D29/64
Filed: 1993-12-16
Abstract: Process appts. (10) has a wall (11) defining a continuous re-entrant lumen (12). An inlet port (13) allows fluid to enter the lumen and an outlet port (14) allows processed fluid to leave. The two ports are asymmetrically arranged in the lumen, defining two flow paths round the lumen, a long path (22) and a short one (23).. Material processing occurs at the lumen wall (11), and at least 2 wall conditioning shuttles (24, 25) are disposed in the lumen: the shuttles pass through the lumen with the fluid flow and are designed to continuously scrape the wall so as to remove any deposits formed on it by the processing operation. The two shuttles are independent and the appts. is arranged so that only only one shuttle is travelling round the longer flow path(22) at any one time, the second shuttle is retained in the short flow path (23) which acts as a shuttle return section. In this position, the shuttle acts to prevent fluid flow between the inlet and the outlet ports. The impact of the first shuttle on the second is enough to knock the shuttle out of the return section (23) into the long flow path (22). The first shuttle is then retained in the short flow path (23), and there is a continual movement of the shuttles around the lumen. The shuttles have front and rear bumpers, wall conditioning elements to clean the lumen walls as the shuttle passes through, and a plug element to prevent fluid flow when the shuttle is retained in the return section of the lumen.
