Title: Arrangement in belt conveyors
Inventor: LOODBERG JAN A T
IPC: B65G15/08
Filed: 1987-10-16
Granted: 1991-01-08
Abstract: ABSTRACT      A belt conveyor with at least one endless belt (1, 1') has two tensile force (longitudinal)-absorbing members (3, 4, 3', 4') which extend throughout the entire length of the belt conveyor and which are each connected to a respective edge portion of the belt and project from the plane of that edge portion. The belt conveyor is sealed at a longitudinal edge through-out at least part of its length. One edge portion of the belt overlaps and extends outside the other edge portion of the belt along the sealed part of the length of the belt conveyor, more specifically with its tensile force (longitudinal)-absorbing member (3, 3') projecting in the same direction as the tensile force (longitudinal)-absorbing member (4', 4) of the other edge portion of the belt. When the belt conveyor has a single belt (1), the two tensile force (longitu-dinal)-absorbing members (3, 4) of the belt project from opposite sides of the belt (1) in the straightened state thereof. When in the case of a two-belt conveyor, each belt has two tensile force (longitudinal)-absorbing members, these may project either from the same side or from opposite sides of the belt in the straightened state thereof.

Abstract: ABSTRACT OF THE DISCLOSURE          In an apparatus for manufacturing a plastic hollow body which hollow body is open on one end and closed on the other, for the forming of a head piece a withdrawal device rests on a ring-shaped nozzle having a ring-shaped nozzle opening, and for the forming of a plastic tubular segment the bottom elements of blow-mold pieces rest on the ring-shaped nozzle, to provide for blow molding of the tubular segment by blow means.  It is desired to be able to produce a hollow body with a closed head piece and a perforated bottom member. This is achieved in that the withdrawal device is configured for forming a head piece which is closed to the exterior; in that the bottom elements of the blow mold which rest on the ring-shaped nozzle form a perforation in the bottom member of the body part of the hollow body, which perforation extends over the region surrounded by the ring-shaped nozzle opening; and in that the blow means disposed in the ring-shaped nozzle is associated with or "operative through" the perforation in the bottom member of the body part of the hollow body. Thereby, a hollow body can be manufactured which has a closed head piece and is fillable via the open bottom member.

The Nd:YAG laser is pumped by an essentially 808 nm semiconductor diode laser beam, which passes through the input mirror and through the KTP crystal into the Nd:YAG laser crystal where it is absorbed.  The 1064 nm radiation oscillating inside the Nd:YAG laser resonator is mixed either with the said 808 nm pump beam or with 808 nm radiation provided by a second semiconductor diode laser whose light is coupled with the 1064 nm beam using a beamsplitter.

Abstract: Abstract of the Disclosure Method and apparatus for in-band, video broadcasting of commands to interactive devices are described. Control data are encoded by subliminally modulating, prior to the remote, composite video broadcast of video program material, a selected sequence of video image fields. The resulting modulated video fields within the viewing area of a television, each having alternately, proportionately raised and lowered luminance horizontal scan lines, are monitored by a light sensitive device positioned adjacent the user's television screen. A semirigid, twisted pair cable connects the device to nearby receiver/transmitter electronics that discriminate the binary data from the program material and amplitude modulate a high frequency infrared (IR) carrier with the data. Interactive devices, e.g. educational aids or action toys, within range of the wireless IR transmission detect energy in this frequency range, decode the commands embedded in the control data, and selectively execute predetermined actions in response to the data-encoded broadcast. In a proposed modification, low radio frequency (RF) electromagnetic radiation emanating from the television's raster scan electronics is coupled by a conventional RF antenna to the receiver electronics, which identically discriminate the binary data, from the program material, for transmission to the interactive devices.
