Abstract: GAS CONVECTION OVEN AND HEAT EXCHANGER THEREFOR                 Abstract of the Disclosure A gas convection oven includes a heating chamber having a gas combustion chamber formed therein and a blower positioned within the combustion chamber for circulating air through the heating and combustion chambers.  The blower defines a low pressure inlet centrally of the combustion chamber for receiving air from the heating chamber and forcing it through the combustion chamber back into the heating chamber around the outer edges of the combustion chamber.  A gas burner extends into the combustion chamber and includes a distally-mounted diverter for dividing and directing flame and combustion products into two different direc-tions.  A bifurcated heat exchanger defines first and second tubular passages which are aligned with and encompass the blower and define inlets aligned with the two different directions for receiving the combustion products from the burner.  The first and second passages terminate in a junction box which passes the products of combustion into the low pressure inlet of the blower such that air drawn from the heating chamber is mixed with the combustion products and then passed over the bifurcated heat exchanger before being recirculated to the heating chamber.

Title: Subscriber unit for wireless digital telephone  system
IPC: H04B1/40
Filed: 1989-08-16
Granted: 1990-08-14
Abstract: ABSTRACT         A digital wireless subscriber telephone unit for wireless connection with a base station.  The subscriber unit has a baseband processor which is coupled to storage means for the baseband functions.  The baseband processor is direct access  coupled  to  a  modem  processor  whereby  the  two processors may communicate with each other.   The modem processor generally  acts  as  the master  in  the  system, although lock-out means may be used in certain circumstances. The signal from the modem processor is converted to an analog signal, which is subjected to deglitching, and the deglitched signal is then upconverted and filtered to form an IF signal which is thereafter amplified.  The amplified IF signal is combined with a signal generated by a synthesizer to provide an RF signal.  On the basis of certain signals received from the base station, the baseband processor produces initiating signals which determine whether the subscriber unit will be in the transmit mode or the receive mode.   In intervals between actuation of the system, a training mode is used wherein a known signal from the modem processor is compared with looped-back signal to produce correction constants to compensate  for undesirable variations in  the  IF,  these constants being stored for use in correcting actual received signals.  During demodulation, the modulated digital signals are  fed  to  the  modem  processor  in  the  form  of  time multiplexed I and Q samples and are demultiplexed.   The demultiplexed I and Q samples are fed to an equalizer and frequency correction circuit for minimization of errors and for production of a frequency correction signal which is used to correct any errors in the timing of the system and in the output of the synthesizer.

Abstract: 1,041,948. Frequency digitizers. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 26, 1965 [May 26, 1964], No. 22348/65. Heading G4H. The excitation function is produced from vocal signals by apparatus which includes means for eliminating the effects of spurious zero-crossings caused by harmonics. The signals are passed through a low-pass filter 2, Fig. 6 (not shown), to a zero-crossing detector 3. Counter 5 is continuously advanced by clock pulses and is reset by detector 3, the output of which also opens gate 6 to pass the contents of the counter to register 11. If no spurious zero crossings have occurred adder/subtractor 9 and decision circuit 10 determine that the sum of the contents of registers 11 and 12 is significantly greater than the contents of register 13 and a shift signal is produced to transfer the contents of each register to the next, register 13 feeding mean value circuit 8. If a spurious zero-crossing occurs, the sum of the contents of registers 11 and 12 is approximately the same as the contents of register 13, no shift signal is produced and the contents of 12 are replaced by the sum from 11 and 12, the next digitized value subsequently being substituted in 11. Circuit 8 includes a shift register 14 containing the last ten digitized values, a register 16 containing the sum of the last ten values (s), adder 15 deriving the new sum (s+tn-tn-10), and a divider 17 dividing the sum by 10 to obtain the mean value.

Abstract: In this process the organic solvents which are obtained in a liquid state in the drying phase are pumped away. The solvents present in the form of a solvent vapor/air mixture are partially condensed by cooling and the fractions of solvent still remaining in vapor form are adsorbed by active charcoal. These adsorbed solvents are recovered by setting up a saturation partial pressure of the solvent in the solvent vapor/air mixture of not more than 0.25 bar. The fractions of solvent adsorbed in the active charcoal are desorbed by means of a solvent vapor/air mixture of the same concentration as in the adsorption process and at temperatures of approx. 100 DEG  to 150 DEG  C.

Abstract: Described herein is a process for enhancing the hydrophobicity of crystalline molecular sieves and also crystalline molecular sieve compositions which have enhanced hydrophobic character and modified catalytic properties. The crystalline molecular sieves are contacted with a silicon tetrafluoride gas mixture at a temperature from about ambient to about 200 DEG C to alter (1) the framework aluminum and silica content, (2) the surface characteristics, and (3) the acidic sites of the molecular sieves with resulting modification of both the adsorptive properties, i.e., enhanced hydrophobicity, and catalytic properties of the molecular sieves. The crystalline molecular sieves can further undergo ion exchange to remove any aluminum fluoride cation species such as AIF<+><+> and AIF2<+>. The crystalline molecular sieve compositions of this invention are useful as selective hydrophobic adsorbents and catalysts.

Abstract: The invention refers to an anchoring system on concrete, on basis of threaded bolts to be installed in holes previously made on the concrete or material to be dealt with. Such improvements are centered in the existence at the internal end of the stud (1), of a trunk-conical head, immediately inside which is located, on the stud (1), an assembly of pieces (3) which determine a cylindrical bush (5), having its internal surface striated, like the external surface of the head, and with its external surface provided with a perimetral groove, on which is located an elastic ring (4) which holds such pieces (3) adapted against the neck of the stud (1). The said groove constitutes a weakening line for such pieces (3), through which, during the tightening, these are obtusely bent outwards, creating a radial and effective overdimensioning of the head, which is going to give rise to the mooring point of the bolt in the widening established at the bottom of its corresponding housing.

Abstract: In ostomy gear with a) circular holding ring with a flange joined by a band to an opening through which an intestinal lock can be introduced, transverse ostomy, from which flange there protrudes a profiled piece to secure another profiled ring connected to an ostomy bag, and b) an ostomy rod designed to be placed underneath the intestinal lock to keep it outside the abdominal wall, the ends of the ostomy rod are bevelled or cut slanted to form slanting surfaces 24 which co-operate with a conical surface 40 on the radially inward side of the profiled projecting part of the holding ring. Advisedly, the conical surface is part of a cone surface with a vertex angle of around 60 degrees, while the slanting surfaces are preferably flat and make an angle with the band, when the rod is thrusting against it, of roughly 120 degrees. One achieves an easier placement of the rod in relation to the holding ring than in the known ostomy gear of similar kind, especially in that one does not need to turn and/or shift the ostomy rod and holding ring in relation to each other after being placed in a plane parallel with the flange, since their mutual angular position is inconsequential, and minor inaccuracies in the positioning of the rod in relation to its own lengthwise direction are adjusted by sliding along the conical surface. <IMAGE>
