Patent EP-0095837-A3 (EP)
IPC: E21B49/08
Filed: 1983-05-09
Abstract: Well testing of either exploration or production wells is 
carried out by locating a hollow member, which contains 
test instruments, in the well bore or within the internal bore 
of a drill string run, in such a manner that fluid flow up the 
bore is caused to take place along the path, at least a por­
tion of which includes testing through the region within the 
hollow member where fluid is in direct communication with 
the test instruments and performing the well tests while per­
mitting such flow through the member to occur or while pre­
venting fluid escape from the member.  
     In the method of the invention well testing apparatus 
may be used for down-hole shut-in purposes even on pro­
duction wells not provided with built-in shut-in facilities.

Patent EP-0130655-A3 (EP)
IPC: F16H61/06
Filed: 1981-05-08
Abstract: In a multi-ratio automatic transmission, the different ra­
tios are selected by hydraulically engaging friction means 
(BR3, BR4, BR5) under the control of hydraulically energis­
ed control means. Hydraulic power for energising both the 
control means and the actuators for engaging the friction 
means is derived from the same source (13a, c). The actu­
ators are supplied from a feeding circuit (42) through relay 
valves (RV) controlled by the control means. A main press­
ure regulator (MPR) is arranged to maintain substantially 
full working pressure (P1) in a priority pressure circuit (36), 
which is connected to the relay valve (RV) supply ports 
through a constricted passage (200, 300) for each relay 
valve (RV4, RV3) and non-return valve means (206) are ar­
ranged to prevent flow through the constricted passages to 
the feeding circuit (42). With this arrangement, the pressure 
(P1) in the priority circuit (P36) can maintain the pressure in 
the actuator of an engaged friction means despite a reduc­
tion in pressure (PK) in the feeding circuit (42) when the lat­
ter is required to supply a relatively large and unrestricted 
flow to take up the slack in another actuator with a view to 
engagement of the friction means associated with the said 
other actuator.

Title: Methods of and apparatus for forming conductive patterns on a substrate
IPC: C23F4/04
Filed: 1985-04-09
Abstract: A method of forming an electrically conductive pattern on a substrate includes the steps of forming a layer of gold (6) on an electrically insulating substrate (2) and coating the gold layer (6) with a photo-resist (8). The resist (8) is exposed to light through a photo mask and the exposed portions of the photo-resist (8) are selectively removed by etching. The now exposed parts of the gold layer (6) are coated with copper (12) and the remaining photo-resist (8) is removed. The exposed parts of the gold layer (6) and the copper (12) are subjected to molten tin (14) which simultaneously acts to dissolve the exposed parts of the gold layer (6) and to form an electrically conductive coating on the copper (12).The process enables the formation of a precise conductive pattern with enhanced reliability.

Abstract: A machine for forming large cylindrical bales of hay has a 
baling chamber consisting of a frusto-conical crop recei­
ving portion (18) and a cylindrical crop discharge portion 
(22). The portions are arranged end-to-end and are defined 
by rolls which are driven to roll the crop round on itself 
into the form of a bale. The bale is compacted in the dis­
charge portion by being forced by incoming crop against an 
abutment plate (52) which is hydraulically controlled. The 
bale is wrapped with twine from a tying device and severed 
by a cutter before being released through a gate (30). The 
whole operation is continuous.  
     In order to produce bales with a desirable density without 
undue stress to the machine, a control system (58) relieves 
the hydraulic pressure affording the resistance to bale 
movement by the abutment plate (52). Sensors (60, 62) de­
tect any drive torque of the machine outside a predeter­
mined range and any lack of advancement of the bale, and 
their outputs are fed to a computer (64) controlling a re­
lief valve (66) enabling the abutment plate (52) to yield 
and the growing bale to advance further.

IPC: B60T13/56
Filed: 1987-05-27
Abstract: A brake booster (42) having a hub (78) with control valve (56) 
located therein. The control valve (56) has a plunger 
(l06) connected to an output rod (62) through a reaction disc (60) and 
to a brake pedal. A sleeve (ll2) which surrounds the 
plunger (l06) is urged toward a shoulder (ll0) on the plunger (l06) by 
a first resilient member (l26). An input applied to the 
brake pedal moves the plunger (l06) to allow air to enter into the 
booster (42) and create an operational pressure 
differential across a movable wall (50) to develop an output force. 
The output force is carried through the reaction disc (60) 
and a reaction force is carried through the plunger (l06) to balance 
the input force. On termination of the input force, the 
reaction force and first resilient means (l26) move the plunger (l06) 
to define a gap between an annular seat (l04) and a 
poppet (ll7) member to allow vacuum to evacuate air from the booster 
(42). When a return spring (59) moves the wall (58) to 
the rest position, the stop (l28) engages the booster (42) housing and 
holds the sleeve (ll2) stationary. The reaction force 
continues to sustain the gap until the operational pressure 
differential is eliminated. Thereafter a static pressure 
differential acts on the poppet member (ll7) and overcomes a reaction 
disc (60) resistance to move the plunger toward the 
annular seat to define a rest position for the plunger (l06).
