Abstract: The preferred embodiments of the invention disclosed herein relate to a tightening system comprising a wrench for rotating and applying torque to a fastener system, means for developing a signal representative of the torque being applied and means for developing a signal representative of the rotation. A control system is operatively associated with the wrench for determining which of the two signals is increasing faster. If the torque signal is increasing faster than the rotation signal, the control system modifies the rotation signal by increasing it until it corresponds to the torque signal, but cannot decrease the modified rotation signal when the increase of the torque signal is less than the increase of the rotation signal. When the increase of the torque signal decreases relative to the modified rotation signal, the control system develops a decision-making signal which is processed to develop a control signal when a yield point of the fastener system is detected.

Abstract: A memory in which each word location for a user word not only contains the bit locations for the actual data but also one parity bit for the parity over the entire word location and one correction bit. A fixed number of word locations are grouped to form a memory location for the storage of a memory word. When a word location is read by a data user, the parity bit indicates whether the word location contains none or one bit error. If the user word contains an error, the other word locations of the same memory location and also the associated correction bits are read to correct one arbitrary bit error in the memory word. In given cases, a plurality of bit errors can be corrected if they are situated in bit positions of the same rank within the word locations for the user words. The chance that a multiple error has exactly this configuration can be enhanced by a suitable arrangement of the bit locations in a memory. Thus, a limited amount of redundancy suffices in many cases. Memory words in different memory banks may have correction bits in common.

Abstract: A controlled volume liquid meter comprises a liquid metering chamber defined between a rigid wall and an opposed flexible membrane wall. Inlet and outlet ports are positioned adjacent the ends of the chamber with the ports defining paths of liquid flow therethrough which are transverse to the direction of liquid flow in the chamber. A pair of plunger members are provided, along with apparatus for alternatingly pressing the plunger members against the membrane wall and inserting the plunger members into the inlet and outlet ports to alternatingly open and close them. In accordance with this invention, the plunger members permit variation of the length of each plunger member, with a spring urging the plunger members to occupy their maximum lengths. As a result of this, the force with which the plunger members press against the membrane wall is limited to a value governed by the spring.

Abstract: A hydraulic braking system, particularly for motor vehicles equipped with anti-skid devices, includes a housing having at least one chamber accommodating a pressure control unit controlling the pressure of hydraulic fluid admitted into brake circuits leading to respective brake-operating cylinders. The pressure control unit includes an actuating piston which subdivides the chamber into an actuating compartment, a working compartment, a supply compartment therebetween which is sealed from the actuating compartment and communicates with the working compartment through a gap between the piston and the housing, and another compartment at the end of the piston remote from the working compartment. An auxiliary piston is accommodated in the last-mentioned compartment and subdivides the same into two spaces into one of which the auxiliary pressure is admitted at the same time that it is admitted into the supply compartment. A sealing ring extends across the gap and permits flow from the supply into the working compartment but not in the opposite direction. The piston has a passage through which the hydraulic fluid can flow between the working compartment and the other space which is connected to a reservoir, unless a valve member engages a seat surrounding the end of the passage that opens into the working compartment. The valve member carries a tappet extending through the passage and through a house in the auxiliary piston to abut an end wall of the housing. When the auxiliary source fails, the pressure in the actuating compartment compresses the fluid in the working compartment so that braking action is still assured. Two pressure-control units can be used side-by-side for separate operation of two brake circuits.

Abstract: O-acetylated glycals react with ceric ammonium nitrate in the presence of sodium azide to provide, in good yield, O-acetylated 2-azido-2-deoxy glycosyl nitrates. These nitrates can be used to prepare 2-amino-2-deoxy sugars, such as D-galactosamine and lactosamine. The O-acetylated 2-azido-2-deoxy glycosyl nitrates can alternately be converted to O-acetylated 2-azido-2-deoxy glycosyl halides which are useful in the preparation of O-acetylated 2-azido-2-deoxy glycosides, which in turn can be reduced to 2-amino-2-deoxy glycosides. Of particular interest are the syntheses of 2-amino-2-deoxy glycosides which correspond to the terminal units of the antigenic determinant for the human A blood group. Attachment of these glycosides to a solid support provides immunoabsorbents which efficiently and preferentially absorb anti-A antibodies from blood plasma.

Abstract: The outlet nozzle for centrifuge drums is used for continuously discharging albumen concentrates. The object was to develop a nozzle in which the discharge of concentrate out of the centrifuge drum into the nozzle body takes place over a smaller diameter than the feeding of the concentrate to the nozzle. According to the invention, this was achieved in that the nozzle consists of the nozzle body with a calibrated through-flow opening arranged at an angle to the axis of the nozzle, a mouthpiece and a cap, the cap being of greater dimensions than the mouthpiece and being fitted onto the mouthpiece on the side of the separating space in such a way that annular gaps are formed which can be adjusted as a function of the medium to be processed, and one or more lateral bores are arranged in the cap, the distance of which bores from the axis of the drum being greater than the distance of the end face of the mouthpiece from the axis of the drum and the bores and the annular gaps being selected to be of such a size that their through-flow rate is smaller overall than that of the calibrated through-flow opening (see Fig. 1). <IMAGE>
