Patent DE-3701407-C1 (DE)
Inventor: H WINHEIM STEFAN
IPC: D21F7/00
Filed: 1987-01-20
Granted: 1988-04-07
Abstract: The steam distributor (1) for the application of steam to a material web (3) such as paper features a main distribution space (9). This is subdivided into a multiplicity of chambers (24), all of which have a steam valve (21). The median lines of the associated discharge openings (35, 36) form an angle of at least 60 DEG  with an axis which stands vertically on a housing wall (2) with vents (8). At least twelve such vents (35, 36) are provided. This leads to very uniform distribution of the steam within the chamber and thus to uniform steaming of the material web below this chamber.

Title: Striking tool for surgical instruments
IPC: B25D9/14
Filed: 1988-01-21
Granted: 1989-07-06
Abstract: A striking tool for surgical instruments has a sleeve-shaped handle part, a tool holder displaceable therein in the longitudinal direction and a piston which is oscillatingly driven and is displaceable in the handle part in the longitudinal direction thereof. The piston has two striking surfaces which come to rest against corresponding contact surfaces of the tool holder and expose the latter to impulses acting in the opposite direction. In order to permit selective generation of impacts in the insertion direction and in the extraction direction without any refitment of the tool it is proposed that the actual stroke of the piston be restricted by stops in the handle part such that it is smaller than twice the stroke which the piston would have to execute from contact of the first striking surface with the contact surface to contact of the second striking surface with the second contact surface when the tool holder is held fast in the handle, and that the tool holder be mounted in the handle part so as to be displaceable relative to the handle part and relative to the piston.

Title: Feed apparatus for gas-flow comminuting machines
Inventor: PALLMANN WILHELM
IPC: B02C23/18
Filed: 1993-05-15
Granted: 1994-11-17
Abstract: In the feed apparatus 1 according to the invention for gas-flow comminuting machines 2, the separation of foreign substances from the comminuting material is brought about mainly by pneumatic sifting. This consists essentially of a sifting passage 19, into which the spread-out feed material trickles slowly via a chute 21, the angle of inclination  beta  of which is slightly larger than the angle of repose related to its surface roughness. The sifting passage 19 is loaded by an air stream which is generated by a cross-flow fan 27 and which is directed by means of a channel 24 approximately tangentially onto a guide wall 22 arranged at the angle of inclination  gamma  and functioning as a pneumatic sorting table, the channel 24 forming with the guide wall 22 an outlet gap 25 for the foreign bodies. The lateral spreading-out of the feed material is ensured by cascade surfaces 11a, b which are arranged at the angle of inclination  alpha in the upper region 9 of the feed apparatus 1 and which are covered with fine-mesh screens 15 for the purpose of separating out fine-grained foreign substances which can no longer be intercepted by the pneumatic sifting. <IMAGE>

Title: Toy projectile comprises housing in which is electronic circuitry of integrated type for emission of audio signals when activated
Inventor: SABEL ANTONI JOHAN
IPC: A63H33/18
Filed: 2005-10-16
Granted: 2007-04-17
Abstract: The toy projectile (1) comprises a housing (4) formed by first (2) and third parts (3), both coupled to each other by a hinge (5). In the housing is an integrated circuit for emission of audio signals when activated. In the first housing part is a loudspeaker for sound emission via three apertures (6). The housing also contains a battery, between which and the aircraft is a switch, which is closed when the housing parts are moved from a closed position to an open position. The outer surface of the housing is slightly adhesive. By operation of the switch the circuit is activated by the battery, so that the audio siganls are emitted. Around the hinge is a torsion spring (7), the ends of which extend outwards as force-transmitting legs (8,9) and press against the inner surfaces of the housing parts, so that the parts are pushed apart. The housing is clsoed by the presence of an adhesive strip (10) which when it is drawn away causes the housing parts to be hinged from each other. By means of a stop the hinged displacement is limited.
