Patent EP-0038158-A3 (EP)
IPC: B23Q3/157
Filed: 1981-04-07
Abstract: A tool 19 selected from a tool storage matrix 16 is held at 
an exchange position Ex in readiness for exchange with a tool 
mounted on a work head 10 which is movable along a main 
beam 13 in a Y machining direction. A carriage 71 is movable 
along a subsidiary beam 70 in a direction parallel to the Y ma­
chining direction and carries a pair of tool grippers 77. During a 
tool change, one of the grippers 77 takes the tool from the ex­
change position Ex and holds the latter while the carriage 71 
moves to the work head 10 where it latches onto the latter by 
means of a latch device 79 (Fig. 9). The other gripper 77 then 
removes the tool from the work head 10, whereupon said one 
gripper inserts the replacement tool in the work head. The car­
riage 71 then unlatches from the work head 10 and moves 
away therefrom, so that said other gripper 77 can return the re­
moved tool to the exchange position Ex. In order that tools can 
also be exchanged in a right-angle head 15 when the latter is 
attached to the work head 10, the grippers 77 are each capable 
of an angular wrist-action movement.

Filed: 1982-09-22
Abstract: A connector for connecting at least two insulated 
conductors, for example telephone line conductors, compris­
es a hollow body and a hollow cap, the cap, in a typical 
example fitting into the body to form an enclosure. The front 
of the body has apertures and guides for admission and

Title: Vehicle suspension systems
IPC: B60G17/052
Filed: 1983-03-14
Abstract: A suspension system for a driver's compartment of a 
vehicle, for example, a cab of a commercial vehicle, has a 
plurality of suspension units (R₁-R₄) providing soft suspen­
sion characteristics for the driver's comfort, and means (E) 
for selectively stiffening their suspension characteristics in 
accordance with certain kinds of movement of the vehicle. 
These kinds of movement include pitch, roll and bounce, and 
the struts are selsectively stiffened in order to counter the 
effect on the driver's compartment of these movements.  
     Each suspension unit may include a volume of gas (4) in 
communication with a gas spring (7), from which it can be 
isolated to stiffen the suspension characteristics. The means 
for selectively stiffening the units is preferably an electronic 
control system (E) which is operative in response to the 
movements of the vehicle, and includes solenoid-operated 
valves (V₁-V₄) to control communication between the units 
(R₁-R₄) and the gas spring (7). The system may be supplied 
from an air-brake system of the vehicle.
Patent EP-0094764-A3 (EP)
IPC: B65D83/76
Filed: 1983-05-05
Abstract: A dispenser for toothpaste consists of a cylindrical 
housing 1 having a nozzle 3 and supported on a base in the 
form of a resiliently compressible cup 5. A rod 13, attached to 
the cup 5, extends towards the nozzle 3 and a piston 17 is 
slidable on the rod 13. The piston carries a steel star ring 21 
which can grip the rod 13 and the wall of the housing 1.  
     Compression of the cup 5 causes the rod 13 to move the 
piston 17 towards the nozzle 3 thereby forcing paste through 
the nozzle 3, and relaxation of the compression allows the 
rod 13 to slide back through the piston 17 which in turn 
remains stationary within the housing 1. A regular amount of 
paste can be dispensed by each compression of the cup 5.
Patent EP-0104758-A3 (EP)
Title: Aroma-generating unit
IPC: A61L9/03
Filed: 1983-08-22
Abstract: An aroma-generating unit adapted to periodically discharge into the atmosphere bursts of aromatic vapor, the non-aromatic intervals between the bursts having a duration sufficient to avoid desensitizing the olfactory response of those exposed to the unit. The unit includes a hollow case whose upper wall has a vent therein and whose side wall has a slot to receive a replaceable cartridge provided with a porous mat impregnated with an aromatic liquid. When fully inserted the cartridge is disposed below the vent and serves to define an air-confined chamber within the case. Disposed in this chamber is an electrical heater that is periodically energized by power pulses to heat and expand the confined air and to produce a positive pressure in the chamber forcing the heated air through the impregnated mat to rapidly volatilize the liquid and to produce bursts of aroma which are discharged into the atmosphere through the vent, which bursts are separated by relatively long, non-aromatic intervals.

Title: Spreading material on a surface
IPC: A01C15/00
Filed: 1984-05-30
Abstract: An agricultural spreader comprises distribution members (11, 12) which rotate to eject material such as fertilizer. The spreader can tilt to one side or the other so as to reduce the spreading distance on one side. This facility enables the spreader to be driven on a field along the same tracks as other agricultural machinery while avoiding waste of material at the edges of fields. Other embodiments utilize braking members which are movable into the path of ejected material to reduce its kinetic energy and consequently its spreading distance.

Abstract: In order to obtain an adequate range of image density 
for half-tone printing an ink-jet print head assembly (14) 
comprises two ink-jet heads (142a, 142b). These are driven
