Patent DE-3736769-A1 (DE)
Title: Hydraulically-powered lift
IPC: B66B1/04
Filed: 1987-10-30
Abstract: Hydraulically-powered lifts (elevators) have a cage that can be raised and lowered by means of a piston connected to it and guided in a hydraulic cylinder, and a pump that pumps hydraulic fluid from a reservoir, against a non-return valve, into the hydraulic cylinder, thus driving the lift cage via the piston. In order to reduce the drive power needed, the invention provides that the reservoir is a closed vessel divided by a freely moving displacer into two spaces, of which one space is connected hydraulically to the pump and the other contains a closed volume of gas, that the pump's direction of rotation can be reversed and it pumps in both directions of rotation, and that a non-return valve effective against the pump is located between the pump and the reservoir's hydraulic space; that non-return valve which lies in each case on the suction side with respect to the pump's feed pipe can be made to open up.

Patent DE-3909159-A1 (DE)
Title: Control device for positive-displacement pumps
Inventor: VOGT RICHARD
IPC: F04B49/02
Filed: 1989-03-21
Abstract: The invention relates to a flow control piston (16), via which the useful flow of a pump is passed to a load. To this end, the flow control piston (16) has a control zone (25) which is sealed by collars (23 and 24) and has a hole (bore) (20) for supplying, and a further hole (21) for discharging the useful flow. Between the two collars (23 and 24) there is, e.g., a conical piston section. The holes (20 and 21), together with the annular cavity (26), form a variable restrictor. At these restrictors, a rotational speed-dependent differential pressure is formed which resets the flow control piston (16) in such a way that the useful flow drops with rotational speed. The excess branch stream is discharged via a control collar (17) to an inlet duct (13) of the pump (Fig. 1). <IMAGE>
Patent DE-3920939-A1 (DE)
Inventor: KUSTER HEINZ
IPC: E05B27/00
Filed: 1989-06-27
Abstract: The lock cylinder has two rotors 1, 2, which are rotatable as a whole in a cylinder casing 3, and a port connecting with the lock bolt is fixed to the second outer rotor 2. In radial bores in rotors 1, 2 and casing 3 are arranged tumbler pins 11, 12, 13, built-up pins 21, 22, 23 and countertumbler pins 31, 32, 33. The pins 11, 12, 13, 21, 22, 23, 31, 32, 33 are dimensioned in such a way that the insertion of a key associated with the cylinder in the key channel 6 unblocks the opening shear line between the second rotor 2 and the casing 3 and blocks the blind shear line between the rotor 2 and the rotor 1. A displacement of the pins in such a way that the blind shear line is unblocked and the opening shear line remains blocked, means that in the case of illegal opening there is only a useless idling action, which does not open the lock. It is also possible to provide blocking means 60 not accessible from the key channel - these means take the form of (a) groove(s) into which one of the built up pins drops to prevent attempted rotation. Figure 4 shows an arrangement provided on either shear line whereby on rotation the rotor necessarily passes into a locked position, the depression 60 containing a tumbler 22 and a countertumbler 32/32' or built up pin is provided as shown. <IMAGE>

Title: Binary conversion process for picture data - counting black pixels with threshold changed from darkest to lightest tone level for pattern recognition
Inventor: BESSHO GOROH
IPC: G06V30/162
Filed: 1990-01-20
Abstract: A binary conversion process maintains an optimum threshold value for a binary conversion which is used when multi-level picture data, which draws an input picture, is converted into black/white picture data with two levels. This process counts up an initial number of black pixels, while a threshold value is changed from a very dark to a very bright tone level. It counts up a second number of pixels, which have a tone level outside the bright tone level. A proportion of the initial number is kept for each of the changed threshold values with regard to the second number, in order to standardise any density in the input picture. The optimum threshold value is set for a binary conversion on the basis of the proportion, which is kept for each of the changed threshold values.
