Patent EP-0136595-A3 (EP)
IPC: F16H39/24
Filed: 1984-09-07
Abstract: A hydraulic drive system for a vehicle includes a 
hydraulic pump capable of utilizing hydraulic fluid from a 
reservoir. The outlet of the pump includes a pressure control 
valve for establishing a predetermined pressure for the 
hydraulic fluid being supplied to a common supply manifold 
for a pair of positive displacement hydraulic motors. Each of 
the motors has an output shah operably coupled to a wheel 
of the vehicle. A common discharge manifold for the motors 
allows hydraulic fluid to be returned to the reservoir. Each 
motor has an output shaft speed proportional to the flow rate 
of the hydraulic fluid therethrough and the flow rate is 
limited to a predetermined maximum level at the predeter­
mined pressure due to internal resistance of the hydraulic 
fluid flowing through the motor. The hydraulic pump is 
capable of supplying hydraulic fluid at the predetermined 
pressure at a supply rate substantially greater than the 
predetermined maximum level of the flow rate for one of the 
motors.

Title: Inking device for a printing machine
IPC: B41F31/04
Filed: 1984-11-20
Abstract: An inking unit for a printing machine including a duct consisting of a plurality of adjacent duct segments mounted individually on the duct roller of the machine wherein each duct segment forms a carrier for at least some of the ink metering elements. The mounting of the duct segments on the duct roller is such that it substantially eliminates the hydrodynamic pressure forces occurring at the duct roller and the ink metering elements during operation. As a result, the duct roller deflection and the influence thereof on the metering gap are greatly reduced so that readjustment of the ink metering elements with respect to one another during operation can be dispensed with.

IPC: G11B20/00
Filed: 1986-05-02
Abstract: A method of protecting machine readable signals re­
corded on magnetic recording media from unauthorized 
duplication and use. The signals to be protected are recorded 
on an authorized magnetic recording medium having a 
relatively high coercivity. An attempt is made by the 
computer to alter predetermined validating signals on a 
recording medium presented for use in the computer. The 
computer is disabled from further using the signals recorded 
on the recording medium if the validating signals cannot be 
read back. If the protected signals have been copied onto an 
unauthorized recording medium having a relatively lower 
coercivity and such unauthorized recording medium is 
presented to the computer, the validating signals will be 
alterable. Thus, an unauthorized copy of the protected 
signals cannot be used since the system detects that the 
validating signals have been changed and disables the 
system.

Title: Borehole dilatometer intensifier
IPC: E02D1/02
Filed: 1986-03-18
Abstract: A highly portable pressure intensifier for use with a borehole dilatometer head having an expandable body defining an internal cavity to measure deformation properties of in-­situ rock masses. The housing (17) of the intensifier (10) comprises two axially aligned interconnecting cylinders (18,19), one of which is of substantially larger diameter. The larger cylinder (18) has a reciprocating piston (54) mounted therein, the piston (54) having a plunger portion (55) which extends axially into the smaller cylinder (19). The smaller cylinder (19) is connected to the cavity of the dilatometer head (11) by means of high pressure tubing (13). The larger cylinder (18) is filled ahead of the piston with a first working liquid. The second cylinder (19), the dilatometer head cavity and the interconnecting tubing are filled with a second working liquid. Increasing the pressure of the first working liquid displaces the plunger portion (55) into the smaller cylinder (19), substantially increasing the pressure of the second working liquid, which latter increase causes the dilatometer head (11) to expand so as to deform the rock of the borehole in which it is placed. A pressure transducer (70) and a linear variable differential transformer (89) are provided for deriving signals representing changes in pressure and volume respectively.
