Title: Improvements in apparatus for removing accumulation of sugar or cake from the filtering walls of centrifugal machines
IPC: B04B11/08
Filed: 1921-06-23
Abstract: 183,028. Daniels, E., McKinlay, G., and Kopke, E. June 23, 1921. Strainer separa - tors; discharging. - A centrifugal machine for the separation of sugar has a discharge plough at the lower end of a spindle 10 mounted for rotary and vertical adjustments, the vertical movement being obtained by means of a rack 11 with semiovlindrical teeth on the spindle. The plough has a cut ting-blade 17 and a spring-pressed scraper 23 which can be projected beyond the cutting-blade to remove the final layer of sugar. A plate 1 provided with levelling screws 4 is secured to the annular top plate of the separator, and carries the bearing for the plough spindle 10. The hub 5 of the bearing has an annular recess to receive the flange of a collar 7 held in position by a locking plate 9 bolted to the hub. A bracket 30 projecting from the hub 5 supports a shaft carrying a hand-wheel 31 which is used to raise and lower the plough by means of the gear-wheels 32, 35 and the rack 11. The collar 7 has a radial handle 43 to advance the plough towards the sides of the vessel, and its advance is made in steps determined by a pawl 64 and ratchet 60. The collar 7 is locked to the spindle 10 for this adjustment by the head 42 of a rod 41 inside the handle 43; the head can be forced against the spindle by means of the threaded end 44. The last tooth in the ratchet 60 is formed separately and is spring- mounted to relieve excessive pressure on the plough when the scraper 23 is in action at the end of the cut. A rod 86 is mounted to slide in bearings on the base plate 1 and carries at its end a yolk 91 with a series of anti-friction rollers 92. This can be moved against the shaft of the machine and held by the latch 90 to balance the machine against the thrust of the plough.

Filed: 1939-06-15
Abstract: 533,566. Repeating systems. SIEMENS BROS & CO., Ltd., and ROSEN, A. June 15, 1939, No. 17485. [Class 40 (iv)] A submerged repeater fed with power current over the transmission circuit, e.g. a co-axial cable, cuts itself out of the circuit and substitutes a direct metallic connection when the power current ceases. In one arrangement, Fig. 1 (not shown), the power supply is alternating and the repeater is connected up and cut out by a relay associated with a rectifier. In a modification, Fig. 2, in which the power source is a battery BW, the relay SW for connecting up the repeater is first operated by a burst of A.C. from the upper contact of a switch PW and then held by the power current when the switch is rapidly changed to its lower position. Operation of testing key KW disconnects the power source to release SW which substitutes a direct connection for the repeater. Condenser QW isolates the inner conductor of the cable to enable di-electric tests to be performed. The repeater shown provides for the transmission of an upper W-E band with amplification at VRW and a lower E-W band without amplification. The direct metallic connection may include the winding of a control relay.

Title: Process for the production of sintered semi-conducting thermoelectric materials
IPC: H01L35/16
Filed: 1961-05-12
Abstract: Bismuth telluride is produced in homogeneous form by pressing and sintering a powder mixture of at least two alloys of bismuth and tellurium, the constitution of the alloys and their relative proportions being such that the product is of stoichiometric composition.  The sintering temperature is chosen to be above the bismuthbismuth telluride eutectic temperature.  Doping additions such as lead or an excess of tellurium may be introduced into one or more of the alloys. In a modification of the process, the time and temperature of sintering are so controlled that full homogenization is not achieved and desirable concentration gradients remain.ALSO:A homogeneous semi-conducting thermoelectric material is produced by a powder metallurgy technique from a mixture consisting of powders of alloys and/or intermetallic compounds, the compositions and proportions of the powders being such as to yield the desired final composition.  The mixture may consist of an alloy containing an intermetallic compound and one component thereof, e.g. Bi2Te3+Bi and an alloy containing the intermetallic compound with the other component thereof, e.g. Bi2Te3+Te.  The mixture may also contain a proportion of the intermetallic compound itself; it may furthermore contain a similar series of compositions from another alloy system such as Sb-Te.  Doping additions exemplified by Pb and Te may be present in one or more components.  The mixture may be first cold pressed and then sintered, or may be hot pressed and then after-sintered, or may be sintered, pressed and again sintered.  The sintering temperature is generally chosen so that some liquid phase is present; in a modification of the process the sintering conditions are so selected that desired concentration gradients are obtained in the product.  In an example Bi2Te3 containing 3% of Te and 0.1% Pb is prepared by fusion and is ground to a size less than 0.06 mm., as is also Sb2Te3 prepared by fusion.  The powders are mixed in ratio 75% mol Bi2Te3/25% mol Sb2Te3, pressed at 4 t/cm.2 and sintered at 380 DEG C. for one hour. In a second example 80% by weight of Bi2Te3 containing 3.6% Te and 0.12% Pb is mixed with 20% of a mixture of Bi-Bi2Te3 eutectic and Te-Bi2Te3 eutectic in a weight ratio 1:1.25, and pressed at 3.5 t/cm.2, followed by sintering in hydrogen or vacuum for one hour at 450 DEG C.  The compact is further pressed at 8t/cm.2 and sintered at 380 DEG C. In a third example 50% by weight of Bi2Te3 is mixed with 50% of bismuth-tellurium alloys containing 85% and 15% respectively of bismuth, the alloys being in such proportions that the total composition is stoichrometrically Bi2Te3 except that each component of the mixture also contains 3% Te and 0.1% Pb. The mixture is pressed at 6t/cm.2 and sintered at 490 DEG C. for one hour, or is hot pressed at 400-500 DEG C. and 1-3 t/cm.2.

Title: Improvements in or relating to a system for regulating the output power of ultra-high frequency amplifiers
IPC: H03G11/00
Filed: 1951-07-24
Abstract: 689,226. Travelling-wave tubes. LAPOSTOLLE, P. M. July 24, 1951 [Aug. 7, 1950], No. 17557/51. Class 39(i) [Also in Group XL(c)] The output of a travelling wave tube amplifier is maintained constant or at its maximum with changes in input signal strength by applying to the delay line of the tube a control voltage derived by amplitude modulating the input signal and comparing the phase and amplitude of the modulating voltage and the modulation envelope of the output signal from the tube. Fig. 2 illustrates the signal input-signal output characteristics of a travelling wave tube for various values of delay line potential. Each characteristic has a maximum value so that if the input signal is amplitude modulated the modulation envelope of the output signal will be of opposite phases on opposite sides of the maximum, and zero at the maximum. Accordingly in Fig. 5 the signal is applied to a first travelling wave tube at 508 and is amplitude modulated by a generator 550, the output which feeds the first anode of the tube through a transformer 551. The amplitude modulated output is fed through a line 509 to the input of the main tube 520 the output of which feeds the load. Part of the output is detected at 552 amplified in a circuit 554 and fed to a phase comparator 557 together with the modulating frequency from the generator 550. The phase comparator produces a control voltage which is amplified at 559 and applied to the helix to adjust the potential to that value which gives the maximum signal output (namely the value corresponding to zero modulation amplitude at the output). The input/output characteristics for different values of helix and first anode voltage Fig. 3 (not shown) illustrate that when it is desired to maintain a maximum value which is constant it may be necessary to apply a fraction of the control voltage to the first anode. The travelling wave tubes shown comprise a cathode, first and second anodes and cylindroconical electrodes for matching into and out of the helix. The input and output are applied through capacitive couplers, for example 510 and 511. Screens 512 and 532 surround the tubes.
