Abstract: ABSTRACT OF THE DISCLOSURE A spacer tube for a hermetically sealed double glazed window in accordance with one aspect of the invention is formed from an elongated strip of metal bent into a hollow elongated tubular shape.  The spacer tube has opposing side wall portions and a base extending between and connecting the side wall portions.  The spacer tube also includes a further wall spaced from the base, such further wall defining a region wherein the longitudinal edges of the strip extend toward each other.  That surface of the base which faces into the interior of the spacer tube has a plurality of closely spaced ridges therein, the ridges being spaced apart in the lengthwise direction of the spacer tube and the individual ridges extending generally transversely of the longitudinal axis of the tube.          The ridges are located at least in the regions adjacent the ends of the spacer tube thereby, in use, to provide for locking engagement with teeth on the arms of corner pieces when inserted endwise into the ends of the spacer tube.  The base is shaped in cross-section so as to define a crest projecting a short distance into the interior of the hollow spacer tube with the transversely disposed ridges being formed in the crest.     The arms of the corner piece are disposed at right angles to one another and they are shaped to fit snugly into adjacent ends of the spacer tubes.  Each arm of the corner piece has a face portion disposed in close proximity to the base of the associated spacer tube when in use such face having rigid teeth thereon which interengage with certain of the ridges defined on the base of the spacer tube.

Abstract: A DEVICE FOR THE EXTERNAL FIXATION OF BONE FRAGMENTS               ABSTRACT       The device for the external (outside of the patient's body) fixation of bone fragments in the surgi-cal treatment of fractures uses a unitary supporting bar which, particularly in the case of shin-bone fractures, is positioned on the front side with a very close spac-ing from the bone and, for reasons of X-ray diagnosis, with a slight lateral displacement.  The use of a system of standard jaws, single-correction and multi-correction jaws and bridging jaws, and the thus facilitated surgi-cal operation techniques, provide for mechanically highly stable fixation of the bone fragments being particularly careful as far as traumatizing is con-cerned, and being particularly favourable with respect to the physical and psychic restraint to the patient during the period in which the device is applied, and with respect to the cosmetic success upon convalescence.          Due to a high degree of standardization, the system of the jaws combines cost-reducing manufacture with un-complicated surgical operation techniques and with all possibilities for necessary corrective measures; the system favours both careful application and cosmetic success.

Abstract: ABSTRACT      A token handling device transmits, using an electro-magnetic carrier,  data,  clock  pulses  and  power  to  a token.  The token transmits data by varying the degree of absorption of the carrier in synchronism with the clock pulses.   These data  transmissions  are  detected  by a receiver in the token handling device, the sensitivity of which is adjusted each time a token is received.    The token could be used in transactions in place of coins, or alternatively could be used for identification purposes in other areas.    Data stored by the token could be used to change the way in which the token handling device operates.   The token handling device may for example  form a vending machine, and the token could be used to alter the pricing of goods vended thereby.    The token handling device may be combined with a coin validator,  in which case  there  is  preferably a common path from an entrance slot for carrying both the tokens and the coins to appropriate testing apparatus.

Abstract: ABSTRACT    An analog signal stacking method and apparatus permits transmission of n analog signals of given spectrum width over a narrow bans communication circuit having bandwidth approximately equal to the spectrum width of one analog signal by compressing the spectrum of each signal by a factor of l/n and frequency offsetting the compressed signals to occupy contiguous frequency bands within the bandwidth of the circuit.  Received signals are processed to remove the frequency offset and expand the baseband signals to restore each analog signal to its normal spectrum.  A dial through circuit permits application of the stacking feature to place two conventional dialed calls on a single line of the telephone network using a circuitfor processing both dial and voice signals.
