Abstract: Dither applied to ring laser gyroscopes in order to counteract lock-in results in an unwanted signal that appears in the gyroscope's output. This patent application describes a way of reducing the unwanted signal due to dither. The proposed solution comprises decoding the gyroscope output signal into respective signals which represent clockwise and counter-clockwise motion, delaying a portion of each of these signals, and combining the delayed and non-delayed signals to derive an output representative of rotation of the gyroscope the dither having a reduced effect on the output.

Abstract: L-Phenylalanine is produced by reacting cinnamic acid and ammonia yielding substance in the presence of L-phenylalanine ammonia lyase (PAL). Combined use of the ammonium salt of a lower carboxylic acid, ammonium carbonate and ammonium hydroxide as the ammonia yielding substance makes it possible to obtain stable PAL activity even at high ammonia concentrations of 10 mol/ℓ and over. Moreover, no salting-out of PAL takes place so that the reduction of effective PAL concentration due to salting-out of PAL can be avoided. Efficient production of L-phenylalanine is therefore feasible.

Abstract: A control circuit for use with a dual port cache tag memory is used to reset a snoop valid bit for an entry addressed through one of the ports. Such port snoops the main memory bus, and a cache tag hit for such port during a write operation to the main memory bus indicates that the snoop valid bit should be reset. In order to avoid errors in resetting the snoop valid bit which can occur due to signal propagation delay, the control circuit resets the snoop valid bit only after a preselected internal delay period.

Abstract: A separator which can be used for separating water from an air/water mixture in an aircraft where the air is to be supplied to electronics equipment comprises a chamber ( 10) containing a generally tangential inlet tube (14) through which a mixture is supplied to a curved side wall section of the chamber to separate water from the air by centrifical action. The efficiency of the unit is improved either by moving the filter unit (18) away from the centre of the chamber (10) or by providing a guide plate (16) between the filter unit (18) and the curved side wall on which the water coalesces. In this latter case, the filter unit (18) can also be offset from the centre of the chamber (10) to give even greater improvement and efficiency.

Abstract: An integrated process for making methanol and ammonia from a hydrocarbon feed stock and air is disclosed. An air separation unit is used to produce substantially pure oxygen and nitrogen gas streams. The oxygen gas is used in the secondary reformer to increase the operating pressure of the reformers so that compression to methanol synthesis pressure may be done by a single stage compressor. The nitrogen gas is used to remove carbon oxides impurities from a ammonia synthesis feed stream in a nitrogen wash unit in addition to supplying the nitrogen reactant in the ammonia synthesis gas. Use of nitrogen wash obviates the need for steam shift and methanation reactions used in prior art processes.

Abstract: The waveguide comprises modular elements, each of which includes ducts (60) which are assembled so as to form a pack and are accommodated, with insulating material (22) interposed, in a metallic protective casing (300) which has a supporting function. The ducts (60) have at least one axial cavity (61,62) which is delimited by walls the thickness of which determines the surface of the current passage section and consequently determines the nominal capacity of the waveguide. The area of the current passage section is increased or reduced in order to correspondingly vary the nominal capacity of the waveguide between preset maximum and minimum values by varying the thickness of the walls toward the inside of the cavity of the ducts, so that the external dimensions of the ducts are constant for all waveguides with capacities comprised between the maximum and minimum values.

Abstract: Transmission and flow-connection processes in digital communication systems are based on using a uniform system clock. This clock is obtained from an external reference clock brought in via exchange lines. The peripheral modules evaluating the external reference clock are arranged in the peripherals of a communication system and connected to a central processor via control lines. In the process according to the invention, the central processor once only transmits an instruction to connect themselves to the clock brought in via exchange lines to the peripheral modules. The suitability of this clock as reference clock is checked by the peripheral modules independently of the central processor which prevents the dynamics in the communication system from being restricted. <IMAGE>

Abstract: An extended consumer communication system uses a signal that is error protected by a block code.

Generally, each of the factors adds redundancy and raises the level of error protection. In this way, redundancy that is associated to a later term of the sequence occupies code positions that are protected by at least one earlier term in the sequence and may in consequence be used for positioning data that is protected by such earlier term, upon surrender of such higher protection level.
