Abstract: A telephone system for providing communications between mobile radiotelephones, portable radiotelephones and land-line telephones, as illustrated in Fig. 1, includes a land-line telephone system including a land-line switching network (20) for providing communication paths for land-line telephones, and a mobile radiotelephone system (30, 40, 50 and 60) for providing communication paths for mobile and portable radiotelephones. The mobile radiotelephone system includes a digital switching network (40), base stations (60), and PCM analog-to-digital (A/ D) and digital-toanalog (D/A) converters (30) interposed between the base stations (60) and the digital switching network (40) and between the land-line switching network (20) and the digital switching network (40). Analog ports are Interfaced by the PCM A/D and D/A converters (30) to incoming and outgoing serial bit streams coded according to pulse-code-modulation (PCM) techniques standardized for telecommunications systems by the International Telegraph and Telephone Consultative Committee (CCITT). 
     The digital switching network (40) receives the incoming serial PCM bit streams and provides the outgoing serial PCM bit streams so that telephone calls are automatically routed between the calling and called parties In the telephone system. Supervisory signalling is detected from the Incoming serial PCM bit streams and processed by a signal processing unit (50) to determine an ordering of time slots for the PCM channels for controlling the Interchange of PCM channels from the incoming serial PCM bit streams to the outgoing PCM channels corresponding to the incoming supervisory signalling from incoming PCM channels is adapted to a pre-established format recognized by the corresponding outgoing PCM channels and multiplexed into the respective outgoing serial PCM bit streams.

Abstract: The removal of manufacturing oils from prepotted, wound bundles of hollow fibers (10) used in dialysis equipment is rapidly accomplished by subjecting the fiber assembly to centrifugal forces acting longitudinally of the fibers. Wicking pads (20) may be used at the outer ends of the fibers during the centrifuging step if desired to counteract the capillary action of the fibers. Following the centrifuging, the fibers are preferably repeatedly immersed, in a vertical direction, in a solvent into which any oil trapped in the pores of the fiber walls diffuses. The repeated rise and fall of the solvent in the fiber lumen continually re-introduces fresh solvent into the lumen to leach oil out of the pores at a rapid rate. 
     In a similar manner, moisture. can then be removed from the fibers by alternately evacuating the fiber lumens in a vacuum chamber and refilling them with warm, very dry air to rapidly remove any moisture contained in the cellulose of the fibers.

Abstract: The disclosure relates to fumigation apparatus particularly for fumigating eggs comprising a cabinet (10) to receive a supply of eggs or any other matter to be fumigated a chamber (28) extending across the top of the cabinet and two ports (23,24) spaced across the top of the cabinet communicating the chamber with the interior of the cabinet. One of the ports (23) contains a motor driven fan (25) for circulating a fumigating atmosphere in the path down one side of the cabinet, up the other side, into the chamber, and then back into the cabinet to wash over the eggs stored in the cabinet and destroy the bacteria thereon. An air inlet duct (40) is mounted at one end of the chamber (28) and an air exhaust duct (40) is mounted at the other end of the chamber (28). Each inlet and exhaust duct contains a barrier formed by a liquid reservoir (45) and a baffle plate (48) extending downwardly into the top of the reservoir from the top of the duct to form a U-shaped passage through the reservoir which can be opened and closed by raising and lowering the level of liquid to the reservoir by means of a separate header tank (50) pivotally mounted on the outside of the duct. The inlet and exhaust ducts can thus be closed to prevent escape of fumigant from the cabinet when the fumigation process is being performed.

Abstract: Gas detecting apparatus: for use in detecting and measuring concentrations of heavy organic gases in ambient atmospheres. 
     A problem with previous gas detecting apparatus has been that noise induced by wind or turbulence has reduced the useful operating range. The invention is able to operate in windy or turbulent conditions by the inclusion of one or more gas permeable screens (18) between the anode (14) and the cathode (1) and providing end plates (17) to prevent the movement of ions between anode and cathode by any other route. 
     The invention may be used to monitor anaesthetics, refridgerants and fire extinguishants and can be used as either a meter or as an alarm.

Abstract: Ein Verfahren zur Regelung des Wärmehaushaltes in einem Schachtofen, insbesondere zur Regelung der thermischen Verhältnisse in unmittelbarer Umgebung der Ofen-Blasformen, sieht vor, das man dem Heißwind je nach den jeweils in der Nähe der Blasformen herrschenden Temperaturen dosierte Mengen an Torf zusetzt, der eine mittlere Korngröße von 0,5-1 mm, sowie einen Wassergehalt von weniger als 25% aufweist. Torf ist ein weiches Material, das die Wandungen der Leitungen nicht angreift. Ferner läst Torf sich bereits durch Verreiben bequem zerkleinern. Auf Grund seines niedrigen spezifischen Gewichtes bringt das Einführen von Torf in den Heißwindstrom keine Schwierigkeiten mit sich. Der Wassergehalt des Torfes, unterhalb 25%, bringt keinen nennenswerten Mehrverbrauch an Koks mit sich.
