Abstract: A wireless system may include a central processor and an access point. The central processor may generate an optical signal on an optical fiber. The optical signal may include an optical local oscillator (LO) signal and one or more carriers. The central processor may modulate different combinations of transverse optical modes, orbital angular momentum, polarization, and/or carrier frequency of the optical signal to concurrently convey respective wireless data streams. The orthogonality of the transverse optical modes, orbital angular momentum, polarization, and carrier frequency may allow many wireless data streams to be modulated onto the optical signal and concurrently transmitted and propagated on the optical fiber independent of each other for transmission to one or more external devices.

Abstract: Liquid is cooled in a batch mode. A batch of liquid is circulated in a cooling loop (12) until  i tjs cooled to a desired temperature at which time it is removed from the cooling loop (12) and a new batch is introduced therein. Preferably, the cooled batch is discharged from the cooling loop by the new batch with as little mixing as practicable. The cooling loop has a desired volume determined by a receiver (36) of suitable capacity. A supply accumulator (14) is used to accumulate liquid to be cooled and from which liquid to be cooled is supplied into the cooling loop. Cooled liquid is discharged from the cooling loop into a product accumulator (16). The liquid may be cooled to a temperature close to its freezing point by freezing a minor portion of the liquid in the cooling loop which is then melted by the liquid of the next batch when it is introduced into the cooling loop. The cooling loop is such as to promote plug flow and to reduce backmixing. In a preferred form, the cooling loop has an evaporative cooler (32) which utilises a suitable refrigerant. The refrigerant is evaporated in each cooling cycle, at a progressively reducing pressure and temperature achieved by withdrawing liquid refrigerant from a closed first vessel (92), evaporating it in the cooler (32) to cool the liquid, compressing the vapour refrigerant by means of a compressor (76), condensing the vapour refrigerant in a condenser (80) and feeding the condensate into a further vessel (94). The liquid refrigerant is withdrawn initially into a flash tank (70), vapour being circulated by a pump (72) to the cooler (32). Valves (88,90,100 and 102) are provided to switch the two vessels (92, 94) around at the end of each cooling cycle.

Abstract: The applicant has devised a turntable platter for record players, consisting of two layers of glass and plastic lying one on top of the other. More precisely the plastic layer can be of a thermoplastic and/or thermosetting material such as polycarbonate, polyacrylic, polystyrene or otherwise. 
     The glass guarantees flatness, rigidity and pleasant appearance of the platter, such features not always being obtainable from the already known metal platters, while the plastic, for its part, guarantees the light weight associated with such material. 
     The glass-plastic combination in the turntable platter represents considerable progress in the particular industrial field as it guarantees reaching several results, including, most especially, the absorption of spurious vibrations, and secondly, optimum sound reproduction quality. 
     More especially, the first of these advantages is such that it is no longer necessary to use mats hitherto added to the already well known turntable platters. 
     The two glass (5) and plastic (2) layers can be joined together by means of adhesive (3) or pushed together along the edges; they can also be of different sizes and shapes. 
     It is advisable that the turntable platter obtained from said layers be provided with an upper layer (6), preferably less than one micron thick, of conductive material, either dielectric or metallic, in order to allow earthing the platter. 
     The outer rim of the platter is transparent in order to permit immediate visibility of the indicator lamp used by the stroboscopic device, hence it is not necessary to use an intermediate light deviating prism.

Abstract: A frequency source uses a temperature controlled crystal to determine the frequency of an oscillator. An oscillator circuit of which the crystal forms a part, and a temperature control circuit are mounted in very close proximity to the crystal so as to minimise variations in its temperature. These two circuits and the crystal are surrounded by a thermally insulating material and enclosed in a relatively large container having temperature controlled walls. The temperature of the walls is held at a value which is less than the temperature of the crystal, but which is significantly above the ambient temperature in which the frequency source is to be operated. To enable the walls of the container to be held at constant temperature, the container is mounted within a larger enclosure with further thermal insulating material being positioned between the container and the enclosure.

Abstract: Disclosed is a clinical analyzer comprising an analyzing section (200) having a reaction tube and photometer, and a sampling section (100) having a sample transfer pipe (201) and centrifugal separator (1) which also serves as a sampler. Sample containers (4) containing blood are set on a plurality of container holders (3a, 3b) through an aperture formed in the cover of the centrifugal separator. A rotor (2) with the container holders mounted thereon is rotated at a low speed intermittently so that each of the container holders is positioned at the container setting position in a predetermined order in which a container holder which is not located adjacently to the previously positioned container holder is positioned next. Subsequently, the rotor is rotated at a high speed for a predetermined period so that the sample liquid in each sample container centrifugally separated. After the centrifugal separation the rotor is rotated at a low speed intermittently so that the sample containers set on the container holders are positioned to the sample take-out position in the same order as in setting the sample containers. The pumping pipe is inserted through a sample transfer hole formed in the cover of the centrifugal separator into the sample container, and the sample liquid is pumped up and transported to the analyzing section. This series of operations is repeated and a plurality of samples are measured for items of analysis by the photometer sequentially.
