Abstract: ABSTRACT OF THE DISCLOSURE           A drying apparatus including a pulse combustor coupled to a processing tube for flowing material to be processed therethrough, the processing tube being coupled to a pair of cyclone collectors for receiving the material flowing therefrom.  An optional recycling section is coupled to the cyclone collectors for flowing vapor from the cyclone collectors back to the upstream end of the processing tube. The pulse combustor includes a rotary valve, a combustion chamber, an inner tail pipe and an outer tail pipe.  The combustion chamber and inner tail pipe are conical and tubular sections mounted in longitudinal compression, and the compressive forces are transmitted externally across the junction of the combustion chamber and tail pipe by a strongback assembly.  The rotary valve includes first, second, and third closely adjacent cylinders defining an interior air chamber.  The cylinders have radially oriented substantially aligned apertures which define an air intake. Air passing from the air chamber into the combustion chamber passes through an annular passage which impedes air flow from the combustion chamber toward the air chamber to a greater extent than air flow from the air chamber to the combustion chamber.  Control systems regulate the product feed rate, the system firing rate, the system flow rate, and the operating frequency of the pulse combustor.

Abstract: ABSTRACT OF THE DISCLOSURE       A  new  movement  translation  element, a so-called transmitter or driving dog, translates the  rotation of the centre  of  gravity  of  an eccentrically mounted eccentric gear wheel to a first shaft while the  eccentric gear wheel simultaneously executes a planetary movement about a second shaft and is characterized  by  a  rigid  body  mounted for pivoting about  first pins which are disposed substantially at right angles to the first shaft.  The rigid  body has in its  symmetry  plane  for  the  first  pins and first shaft axially directed,  tooth-like  projections  which  fit with negligible   play   into   two   radially  counter-directed apertures in the  eccentric  gear  wheel  which  allows the projections to  execute radial sliding reciprocatory motion in the apertures simultaneously  as they  execute a rolling movement therein, and the rigid body pivots round the first pins.

Abstract: An internally pressurized envelope according to the present invention has spaced inner and outer surfaces characterized by a load deflection curve having a first and second region. The first region reflects the compliance upon initial application of a load and the second region reflects the compliance after the initial application of the load. The curve is such that the compliance of the first region of the curve is less than the compliance of the second region of the curve. The envelope is particularly useful as a cushioning layer and can be used in shoes.

Abstract: 1432694 Treating wood E G L ERIKSSON 27 April 1973 [27 April 1972] 20160/73 Heading D1P Wood is treated with a condensate solution of formaldehyde and/or paraformaldehyde in phenol or a substituted phenol, the solution subsequently being hardened in the presence of a condensing agent e.g. an acid or alkaline vapour. The solution is substantially free of other solvents. Preferably the heat treatment is effected While contacting the wood with the vapour, e.g. gaseous ammonia. Alternatively, the condensing agent may be present in the treatment solution, and may be a salt of a strong acid, e.g. ammonium chloride or aluminium chloride. The treatment is carried out at elevated temperature. The treatment may be at atmospheric pressure, a slight over-pressure or at elevated pressure, to cause the agent to penetrate the wood. The wood may be pinewood or spruce boards, plywood, veneer, telegraph or fencing poles, railway sleepers or surface chips for chipboards. In the latter case the solution may be applied by spraying.

Abstract: In the process of packaging letter envelopes and mailing wallets, the packaging batch is counted in the end region of the production machine, and the individual article of the packaging batch corresponding to the specific batch size is at least identified or optionally pushed a certain distance sideways out of the path of movement of the packaging batch in one direction or the other as a counting article. The packaging batch is deposited on a conveyor belt and conveyed away. A stack support keeps the stack approximately vertical on its end face. The stack support is advanced in front of the stack at the conveying speed of the conveyor belt. As soon as the counting article at the end of a stack has arrived at a transfer point which is at a relatively long distance from the production machine, a separating device is introduced into the stack, with the result that the following portion of the packaging batch is temporarily halted. During this time, the separated stack is pushed, at the same height, into an open container via a slide track. Subsequently, the stack support is guided back to the separation point, and the separating device is retracted from the end face of the following packaging batch, after which the stack support once again takes over the vertical guidance of the packaging batch, until the next counting article has arrived at the separation point. The automatic packaging machine for letter envelopes and mailing wallets has several devices, by means of which the individual steps of the process are executed partly alone and partly in combination with one another.

Abstract: An electrically operated driving device includes a bell type armature motor with a hollow shaft containing an internal thread. An axially extending threaded spindle is located within and in threaded engagement with the shaft. The rotation of the hollow shaft is transformed into liner motion effected by the spindle. The movement of the threaded spindle relative to the hollow shaft can afford a different speed and/or a different direction of rotation. The armature is of the iron-free or ironless type. The device operates at the least weight almost inertialess, and converts the produced power without significant friction losses and it can be used in a very limited space.

The probes are mounted apart both lengthwise and across the pipe section. The probes are mounted at an angle  alpha  to the fluid flow, 20 DEG < alpha 60 DEG . Without any signal analyses, the probes will register whether the fluid flow contains solid material if the thickness of the probes is reduced 0.1 %.

Abstract: REGISTER AND ARITHMETIC LOGIC UNIT       ABSTRACT Register and arithmetic logic apparatus for use in processing digital data and which provides a split pipeline architecture that operates on multiple data formals. A register file (444) is employed to store data words. An arithmetic logic unit (450) processes the data words by means of two parallel arithmetic logic units (450a, 450b) that provide fixed point and floating point arithmetic processing operations, respec-tively. The two parallel arithmetic logic units (450a, 450b) permit processing of a plurality of predetermined data processing formats, including dual 16 bit fixed point, 32 bit fixed point, 32 bit floating point and logical data processing formats. Post-pro-cessing registers (454, 456) provide for a limiter/shifter register, a length selectable first in, first out buffer for controlling the length of the register pipeline, and logic which provides for queuing of the processed data words. The register file (444) and the fixed point arithmetic logic unit (450a) may be selectively coupled together to function as an accumulator. This function permits processing of the data words such that two 32 bit data words are accumulated into a 64 bit data word, or the dual 16 bit data words are accumulated into two 32 bit data words. Processing using the dual 16 bit format employs a potential overflow scheme that permits a variety of gignal pro-cessing algorithms to function with relatively compact code.
