Abstract: ABSTRACT            A  method  is  disclosed  for  manufacturing  a  reaction sintered composite article which comprises at  least one ceramic  component.  The  method  comprises  preparing  a particulate mixture of precursor powders  leading to the formation  of  said  composite  material  upon  reaction sintering,   pressing   said  particulate  mixture   to  a self-sustaining   body,  heating  said   body  up   to  a temperature below the temperature at which  the  reaction sintering is initiated, comminuting the heat treated body, selecting particles of a suitable grain size distribution, pressing said particles into shapes of desired size and configuration, and heating said shapes up to a temperature at which the reaction sintering is initiated. The reaction sintered  body  comprises  borides,  carbides,  nitrides  or silicides of a transition metal of the groups IVb, Vb or VIb of the periodic table (comprising titanium,  hafnium, zirconium,    vanadium,    niobium,    tantalum,    chromium, molybdenum and tungsten), and a metal oxide.  In the case that   the   composite  material   comprises   A1203,   TiB2 and facultatively A1,  the precursor powder may comprise TiO2,   B2o3   and   Al.   Composite   bodies   of   sizes, shapes,   varying   compositions   or   other   particular configurations which do not allow for the preparation of the  final  bodies  in  one  operation  are  produced  by preparing  sub-sections  of  precursor  shapes  which  are pressed  in  a  first  pressing  operation,  assembled  to a shape  of  essentially  the  final  configuration,  again pressed and reaction sintered.

Abstract: Abstract An improved switching control apparatus for switching a number of alternating current (AC) devices, such as AC vend motor uses a reduced number of AC power switching elements such as relays by dividing the AC devices into two groups and using one switching element to select which of the two groups is to be selected, and using an additional number of AC power switching elements each of which is connected to one of the AC devices in each of the two groups to select which one of the AC devices is to be activated.  Preferably, a further AC power switching element is used to control the flow of power to the group determining AC power switching element so that switching transients can be minimized.

Abstract: Abstract Of The Disclosure The addition of vaporized solvent to injected steam in a fracture-assisted steamflood process provides surprisingly significant enhancement of the process as compared to both the  basic  fracture-assisted  steamflood  process  of  the Britton et al. 4,265,310 patent and to a conventional matrix drive type steamflood process utilizing solvent.  Much lower solvent  losses  to  the  formation  are  observed  than  are generally  provided  by  conventional  matrix  drive  type steamflood processes utilizing solvent.   Dramatically dif-ferent  effects  of  the  addition  of  heat-scavenging  water follow-up after the steam injection phase are observed as compared to  a  conventional  process  utilizing  solvent. Directly  opposite  effects  are  observed  from  changes  in solvent composition as compared to conventional matrix drive type steamflood processes utilizing steam; for the present invention SOR is decreased by going to lighter solvents, whereas  with  a  conventional  process,  lighter  solvents increase  the  SOR.    Furthermore,  the  solvent enhanced fracture-assisted steamflood process provides significantly lower overall SOR and significantly higher percentages of recovery of original oil in place, as compared to a conven-tional steamflood process utilizing solvent.

Abstract: Method of operating an apparatus for continuous gravimetric dosing and pneumatic transport of bulk material which is conveyed by conveyor over a measuring section in which the conveyor is designed as a rotor 1 with an essentially vertical axis, which is arranged in a pressuretight manner in a housing 2 and provided with transport cells 13a, 13b. The housing 2 has a filling opening and an emptying station with connections to the lines of a pneumatic transport system. In the interspaces 22, 64, 72 between the rotor 1 and the housing 2 and/or in the rotor 1 itself, air under pressure can expediently be introduced. In this way, during transport from a storage container, through the filling opening, the pockets of the rotor and the emptying opening, and in particular at the transitions between the moving and the fixed parts, material being transported can be prevented from entering said interspaces and settling in these and in this way reducing the weighing accuracy and bringing about increased wear of the apparatus parts and at the same time resulting in a greater torque being necessary to drive the rotor. <IMAGE>

Abstract: For synchronizing a data block in a receiver, there are transmitted consecutively and prior to the data block: a first bit sequence of alternating "0" and "1" levels for determining the bit clock and a second bit sequence for determining the block synchronization by correlation. In known methods of determining the bit clock, the phase range of the individual bits of the received digital signal is divided into sub-intervals and the phase position of the bit clock is determined on account of the number of edges in these sub-intervals. In order to avoid fading and phase jitter having a detrimental effect on the bit synchronism, more specifically when transmitting through radio transmission links, N-phase-shifted clocks having the same clock frequency are generated in the receiver by means of which the first bit sequence is sampled. The clock for which the number of sample-value changes of the first bit sequence is established as having a predeterminable minimum value during a predeterminable time-interval is utilized as the phase synchronous bit clock.

Abstract: In an embodiment, the tensioning arrangement comprises an axially non-displaceable piston 10 fastened to a fixed point on the engine, with two piston surfaces 20, 21 which are oriented in opposite directions and, together with a piston housing 15 arranged around the piston 10, delimit two working chambers 22, 23. The piston housing 15 is fastened to the free end 6 of the lever 2 and has two inlets 30, 31, through which pressure oil is conducted to the two working chambers 22, 23 which are furthermore interconnected via a narrow throttle passage 25 in the piston 10. The narrow throttle piston 25 means that only relatively long unilateral action on the piston housing 15 in relation to the piston 10 will bring about a displacement of the central position of these elements relative to one another. At the same time, the narrow throttle passage 25 brings about effective damping of rapid vibration effects. In this way, automatic continuous tightening of the transmission chain is achieved, in such a manner that retightening the chain becomes superfluous. <IMAGE>
