Granted: 1988-02-11
Abstract: A variable displacement, axial piston pump has workports (10 and 12) and a swashplate (14) controlled by two piston actuators (16, 18) for selecting the displacement, and pumping direction of the pump. Control is effected by way of a control valve (24) with a manually positionable spool (26) and a sleeve (28) connected to a follow-up linkage (30) from the swashplate. The outputs (40, 42) of this valve are connected to the piston actuators (16, 18) by way of an override valve (50) which normally assumes the illustrated position under the action of a bias spring (66). Whichever port ( 10, 12) is the high pressure port is connected by a shuttle valve (36) not only to the control valve (24) but also to a pilot (68) for shifting the override valve (50) to its alternative position in which the workports (10, 12) are connected to the piston acutators (16, 18) to drive the swashplate rapidly back towards neutral, should the pump pressure become too high.

Abstract: For charging a battery (6) from different input voltages use is made of a flyback converter in which during the forward interval a linearily increasing current flows through a transformer primary winding (n1), which current is turned off by a first switch (S1) at a value which is dictated by switching means (3). During the flyback interval the energy stored in the transformer (Tr) is then supplied to the battery in the form of a charging current via the secondary winding (n2) and a diode (D1). The voltage pulses appearing across the secondary winding (n2) during the forward intervals are applied to an integrator (11) via a third switch (S3), which integrator integrates these voltage pulses. If the output voltage of this integrator (11) exceeds a first threshold value a threshold circuit (12) is activated and turns on a second switch (S2) to disable the flyback converter. If subsequently the output voltage of the integrator (11) decreases below a second threshold value, the second switch (S2) is turned off again by the threshold circuit (12), so that the flyback converter can be restarted. In this way the average value of the voltage across the secondary winding during the forward intervals is maintained substantially constant. Thus, the flyback converter constitutes a constant-power source, the power supplied to the battery (6) being constant and independent of the input voltage.

Abstract: There is disclosed herein a CRC calculation circuit which can calculate CRC checkbits on 8 bits of raw input data per cycle of a byte clock. The calculation apparatus uses 8 rows of shifting links with the inputs of each row coupled to the data outputs of the preceding row. Each shifting link shifts its input bit one bit position toward the most significant bit, and selected shifting links perform an exclusive-OR operation (84) between their input bits and the output of an input exclusive-OR gate which exclusive-OR's (84) one input bit with one of the bits in the most significant byte of the checksum register (30). A byte wide output (70) bus is used to access the final checkbits from the checksum register (30) by disabling the array of shifting links during the output cycles so that the bytes of CRC data can be shifted into position through the array one byte per each cycle of the byte clock. Preset logic for forcing all logic 1's into the data inputs of the first row of shifting links is provided such the machine can be preset during the first clock cycles of the CRC calculation. Several differenct architectures are disclosed for allowing separate calculation of CRC bits on a header packet and a data packet where the CRC bits on the data packet may be calculated on the data alone or the data plus the header and the CRC bits for the header. Logic for allowing CRC calculation to be performed on all bytes of a message while excluding some selected number of bits in the first byte is also disclosed.

Abstract: For improvement of the phosphate redissolution taking place under anaerobic conditions, the treatment is conducted under anaerobic conditions, preferably in a settling tank, into which unsettled raw sewage and a return sludge from the secondary settling tank are introduced. The sludge retention time of the return sludge is generally over 5 hours, preferably 10-24 hours. In any case, the sludge detection time exceeds the hydraulic detection time. The new process can be performed by using most existing plants with relative small investment expenditures and provides a phosphorus elimination on the order of magnitude of 90%.

Abstract: A pickup head (13) derives reproduced signals from each of the concentric recording tracks of the magnetic disc (76). A peak detector (33) detects reproduced signals and compares peak valves derived before and after the head is moved. Motion of the head is effected by a drive motor (64) which is pulsed to move the head radially inwardly or outwardly, one step at a time. The peak signal comparison in the detector allows the position corresp. to the max. reproduced RF signal level to be determined by a peak position operating circuit (34), coupled to the peak detector. The signals input to a position memory (35) from the operating circuit (34) represent the deviation between the mechanical centre of the track and the position of the peak detected signal. The memory stores the deviation-representative signals for each of fifty main tracks and a cue track. Signals from the memory are applied for positioning the head to the position of greatest signal when the disc is subsequently replayed.

Carrying limbs (6) with hooks (7) are arranged in the plane of the supporting legs (3) in order to receive the lower reinforcement mat. In order to increase the stability of the holder when loaded by the lower mat, the supporting legs (3) are bent inwards at the bottom, the bends (10) lying somewhat above the apex (8) of the hooks (7), as a result of which the resulting force acts on the carrying legs (1) in the direction of the bearing surface.
