Granted: 1992-04-28
Abstract: A lightweight can assembly for housing and protecting the gas generator and inflatable bag of a passenger side restraint system includes a tether in the bag flush with the mouth of the can and at the center which retains the spreading forces at the mouth of the can upon bag deployment. This allows for a lighter section at the mouth of the can and eliminates the need for flanges along the sides of the can, which flanges would undesirably increase the envelope.

Title: Rare earth element-doped optical waveguide and process for producing the same
Inventor: NAKAZAWA MASATAKA
IPC: G02B6/12
Filed: 1991-04-16
Granted: 1996-12-03
Abstract: A  core  waveguide having a  substantially  rectangular cross section,  with  the  width   thereof  greater  than  the thickness   thereof,  is  provided in a cladding  formed  on  a substrate, and a rare earth element-doped layer is provided  in the  core  waveguide  along the waveguiding  direction  of  the waveguide.  With the width  of the core waveguide  set  gearter than  the  thickness   of  the  core  waveguide,  good  optical confinement  in  the  width  direction  of  the  waveguide   is obtained, which enables light to be absorbed by the rare  earth element-doped  layer  efficiently and  concentratedly.   It  is thereby  possible  to  achieve  a  marked  improvement  in  the excitation  efficiency of excitation power.  Thus, an  enhanced exciation  efficiency is achieved with less addition of a  rare earth element, and a high-gain optical amplification  waveguide free of concentration extinction is provided.

Title: Spar-to-hub joint for a flexbeam helicopter rotor
Inventor: BYRNES FRANCIS E
IPC: B64C27/48
Filed: 1991-05-14
Granted: 2002-03-12
Abstract: A flexbeam helicopter rotor having an improved connection between the flexbeam and the hub of the con-necting pin variety but in which the high tensile fi-bers of the flexbeam do not wrap around the connecting pin, wherein the blade centrifugal loads and the blade lead-lag loads axe reacted by the connecting pin at a station where it passes through drilled holes in the flexbeam inner end, and wherein the blade flapping mo-tion imposed loads are reacted through two load paths in the flexbeam-to-hub connection, the first load path being created by a prying reaction between the flexbeam and the hub connecting flanges, and the second load path being created by the differential bending reaction between the flexbeam at the station of the drilled holes and the connecting bolts. Further, there are means to decouple the loads and decrease the maximum load in at least one of the load paths created by the aforementioned prying reaction and the aforementioned bending reaction so that they are substantially spaced along the flexbeam axis of rotation from each other to thereby permit the use of a minimum thickness flexbeam, and gain the attended advantage of reduced rotor weight and size, and which flexbeam-to-hub connection has the additional advantage of a reduced flapping hinge ef-fecting offset, or flapping axis, from the prior art type of connection.

Abstract: Abstract (in connection with Fig. 1) 1.   A device  for supplying  packaging machines with packaging material.   2.1. The supply of packaging machines with packaging material is an intricate problem due to the efficiency of  the  packaging  machines,  in  particular  with  the production of cigarette packages. For the production of cigarette packages  consisting of  several  components, e.g. soft packages or hinge-lid packages, tin foil and paper or cardboard have  to  be processed as various packaging materials. The packaging material is supplied in the  form of bobbins  (tin foil  bobbins 13,  paper bobbins 14).   2.2. The packaging machine is equipped with two bobbin storages (23, 24) for the reception of tin foil bobbins (13) or paper bobbins (14). The bobbin storages  (23, 24) are supplied with the various bobbins (13, 14) by a common supplier, i.e. a floor-mounted supplier (15).   2.3. The various bobbins (13, 14) are removed from the bobbin  storages  (23,  24)  by means  of  a  transversal supplier (transport cog 51) and conveyed to a common downward delivering bobbin supplier (50). It transports the bobbins to superpositioned bobbin aggregates (42, 43).  Here the packaging material  is processed,  i.e. withdrawal from the bobbins.

Inventor: KOLBECK GITTE JORGENSEN
IPC: F16K31/165
Filed: 1992-09-01
Granted: 1998-05-19
Abstract: A valve controlled in dependence on differential pressure with a set-point setting facility, comprises a valve housing (4), a diaphragm housing (16), and a setting device (3) which is removable as a unit from the diaphragm housing (16).  A pin (36) connected to the diaphragm (23) projects in a sealed manner from the diaphragm housing (16).   The set-point spring  (50)  extends between an adjustable supporting plate (51) and a spring plate (52).  The forces of the set-point spring (50) are transferred by way of a releasable coupling (64) to the pin (36).   The coupling (64)  is in particular designed to transfer tensile forces.  In this manner, the set-point spring can be adjusted  or  exchanged  at  any  time.    In  addition,  detrimental transverse forces originating in the set-point spring are prevented from being transferred to the valve rod. The valve is therefore accessible and of low friction.
