Patent EP-0315308-A3 (EP)
Title: Cylindrical coordinate measuring machine
IPC: G01B5/20
Filed: 1988-09-19
Abstract: A machine for measuring objects of generally circular 
cross-section includes a platen movable vertically 
along a measuring axis and three measuring heads having 
probe tips which are located along radii arranged 
symmetrically about the measuring axis. Linear and 
rotary measuring devices respectively determine the 
position of the platen along the measuring axis and the 
angular position of the platen. Each measuring head 
had measuring devices for determining the position of 
its probe tip with respect to the measuring axis. The 
circular object is placed on the platen with its axis 
generally coinciding with the measuring axis and the 
probe tips are urged into contact with a 
circumferentially extending surface on the object. 
Then the platen and the object on it are moved axially. 
During the axial displacement, the radial position of 
the probe tips is measured at intervals and the axial 
position of the object for each interval is measured by 
the linear measuring device. From the measurements 
derived from the measuring heads it is possible to 
construct an axial profile of the object and to locate 
the axis of the object. Also by rotating the platen 
with one of the probe tips in contact with the 
circumferentially extending surface on the objects it is 
possible to construct a circumferential profile and to 
detect any deviation from true circularity.

Title: Convection cooling vessel for materials exhibiting surfaces
IPC: F27D7/00
Filed: 1988-10-26
Abstract: A convection cooling vessel for materials exhibiting surfaces in arrangements with interspaces which can be flowed through, in particular of block charges made of light metal semifinished products, has a fan which delivers into an exhaust duct and on the suction side of which a forked pipe is arranged; on each leg of the forked pipe, there is a shut-off and control valve. Provided symmetrically in relation to the material are inflow ducts which are assigned to the legs of the forked pipe. Each inflow duct has a further shut-off and control valve. The shut-off and control valves in the forked pipe and in the inflow ducts can be adjusted in such a manner that, because of the suction effect of the fan, the material can be flowed through in the main flow or in the part flow and the flow direction of the cooling medium can be reversed. <IMAGE>

Title: Photosensitive material for electrophotography and method for making same
IPC: G03G5/05
Filed: 1989-11-07
Abstract: This invention relates to a photosensitive material for 
electrophotography which comprises an electrically 
conductive support of a desired shape and an organic 
photoconductive layer formed on the substrate. The organic 
photoconductive layer is formed from a solution of an 
organic charge-generating compound, an organic charge 
transfer compound and an organic resin in an organic solvent 
after low temperature treatment thereof wherein the solution 
is cooled to a temperature sufficient not to cause the 
solutes to be precipitated or the solution to be coagulated 
for a time enough to allow interaction between the compounds 
and the resin binder and is returned to room temperature. 
This solution is applied to the support and dried to form a 
photoconductive layer on the support. The photoconductive 
layer may be of a single-layer structure or a double-layered 
structure wherein at least one sub-layer should be formed 
from a solution subjected to the low temperature treatment. 
A process for making the photosensitive material is also 
described.

Patent EP-0352941-A3 (EP)
Title: Apparatus and method for flow control
IPC: A01K79/00
Filed: 1989-07-13
Abstract: The invention provides an apparatus and method 
for handling a solid/liquid mixture, for example for 
conveying fish immersed in a fish/water mixture. The 
apparatus has a receiving chamber (12) to receive the mixture 
through an inlet valve (16) when the chamber is subjected to 
low pressure, and to discharge the mixture through an 
outlet valve (18) thereof when pressure in the chamber is 
increased. A quantity sensor (73) is responsive to a 
predetermined quantity of mixture within the chamber (12) to 
isolate the chamber from low pressure when the 
predetermined quantity is reached. The inlet valve (16) is 
positioned adjacent an upper portion of the chamber above 
a maximum upper level of mixture within the chamber, and 
has seat clearing structure to clear the inlet valve seat 
of solids when flow therethrough ceases. An inlet flow 
sensor (34) is responsive to inlet flow of mixture through the 
inlet valve and raises pressure in the chamber when the 
flow therethrough stops, to provide time for solids to 
clear the inlet valve (16) before closure thereof. The 
quantity sensor (73) also has a mode selector for selecting 
mode of operation of the apparatus which is responsive to 
quantity of mixture and controls pressure changes within 
the chamber. A valve/switch which controls actuation of 
controls for changing pressure within the chamber is 
magnetically responsive to flow sensors (34, 92) disposed within 
inlet and outlet ducts to permit actuation of the 
valve/switch without mechanical contact therewith. This 
isolates the valve/switch from contamination with the 
mixture in the duct and vice versa.

Title: Cleaning vehicles
IPC: E01H1/08
Filed: 1991-07-15
Abstract: A self-propelled cleaning vehicle (10) comprises matter removal means (18) including primary brushes (24,26) and an additional or third brush (28). The third brush (28) is mounted on a brush mounting arm (46) comprising inner (48) and outer arm (50) portions, pivotally interconnected (52), and controlled by a control linkage (58) interconnecting them and actuated by a remote actuating ram (72) at the inboard end of the assembly. The outer arm portion (50) is of telescopic construction for length-adjustment. The telescoping portion is provided by two parallel rams (98,100). Oil flow to the hydrostatic motor (104) passes through the rams and their piston rods themselves. The pressure on the piston is used to telescope the rams (98,100). When the third brush (28) is in use, contour-following means enables the inboard primary brush to follow the peripheral contours of a surface it is sweeping without driver intervention. Such automatic contour-following is activated by driver-controlled selection (113) of a contour-following control mode which causes the inboard brush to move outwards until it meets, for example, a gutter profile. Position sensing switches (124A) enable the primary brushes (24,26) to automatically adopt standard sweeping positions when a non-contour following mode is selected. <IMAGE>
