IPC: G06G7/161
Filed: 1964-03-19
Abstract: 1,049,802. Electric analogue calculating. MONSANTO CO. March 5, 1964 [March 20, 1963; June 3, 1963], No. 9378/64. Heading G4G. An arrangement for obtaining the quotient of two quantities comprises a capacitor across which sawtooth pulses are produced, the amplitude of the pulses being dependent on a first signal, and the pulse duration being dependent on a second signal. As described with switch 44 in the position shown, capacitor 56 is charged towards a voltage determined by the speed of rotation of generator 28, and is periodically discharged through contacts 46 at a rate determined by the speed of rotation of generator 34. The amplitude of the sawtooth voltage thus developed across the capacitor 56 is dependent on the ratio of the rotational speed of shaft 20 to that of shaft 22. If switch 44 is moved to its other position the charging voltage for capacitor 56 is the difference between the voltages of generators 28 and 34 and the output is proportional to the difference in speeds divided by the speed of shaft 22. In a modification, Fig. 5, the discharge of the capacitor 124 may be controlled by either generator 136 or 138 depending on whether switch 166 or 168 is closed. Compensation for the effect of different closure time of contacts 160, 164 is made by means of adjustable resistors 174, 176 and the charging voltage is controlled by potentiometers 140, 152.

Title: Piston cylinder device
Inventor: HEILIGER ROBERT WILHELM
IPC: F15B15/14
Filed: 1993-05-10
Abstract: A method is described for protecting piston cylinder devices against corrosion by a pressure resistant thermoset or cured material coating. At least the outer and inner cylindrical surfaces, for example, of a mine prop, that cooperate with a sealing device, are coated with a three-dimensionally cross-linked, cured or thermoset material having a sufficient thickness on the one hand for providing the intended protection against corrosion and on the other hand to avoid excessive radially directed elastic deformations of the coating. An additive is included in the coating to improve the dry lubricating characteristics, and thus the cooperation between the coating and the sealing devices. The three-dimensionally interlinked thermoset material fills all surface irregularities so that gas and water pockets, for example, in a mine prop, are avoided.

Title: Memory data and address checking
Inventor: HARRIS JEREMY
IPC: G06F11/10
Filed: 1999-07-09
Granted: 2001-07-11
Abstract: An integrated solid state memory device 22 (and Fig. 8) includes addressable memory locations 33, and receives an address identifying at least one memory location, and associated verification information (e.g. parity or error correcting information). Within the device, decoding logic 31, 32 decodes the received address, and verification logic 30 verifies the received address. The verification logic can be configured to prevent access to, or modification of, the memory locations, and/or prevent output of the content of an addressed memory location, where address verification is negative, under which circumstances an error signal can be generated and used to report a fault to the memory controller (20, Fig.2) and/or processor (12, Fig. 1), or to cause a retry of the addressing operation. The address verification can be performed at memory bank level if the device includes separate memory banks (Fig. 7). The verification logic 30 can also verify data supplied to the data buffer, such that storage of the data is prevented where data verification is negative: the independent claim relates to this data verification aspect.
