Title: Driving machine for lifts
Inventor: LIEBETRAU CHRISTOPH
IPC: B66B11/08
Filed: 1995-03-22
Abstract: In this  simply and compactly constructed driving machine,  damages caused  by  axle  sagging  and  deformations of teeth,  which occur on peak loadings, of a gear (8) are avoided.  For this purpose, the drive pulley (6) is borne to be rotatable on one end of a stationary axle (11), which is fastened at a bearing block (3) arranged on the base plate (2) of a machine frame (1).  The drive with gear (8), electrical motor (9), brake (10) and rotation  transmitter  (12)  is  arranged  co-axially overhung  at  the drive pulley (6)  and secured  against rotation by means of two elastic torque stays (5) fastened at the machine frame (1).  Adjustable damping elements installed in the torque stays (5) enable a load-moment-dependent deflection of the drive  (8,  9,  10)  in  the  sense  of rotation  and  thereby a load measurement at the driving machine.

Title: Method of modifying keratin fiber
Inventor: HOJO HIROSHI
IPC: D06M101/00
Filed: 1995-05-31
Abstract: An improved method of modifying keratin fiber represented by wool is disclosed.  Mechanical force is applied to keratin fiber in the presence of an aqueous solution of a transition metal salt to weaken and destroy the structure of the parts under the keratin layers in scales (surface cells) so that the transition metal may be introduced in the under-keratin layers locally at high a concentration.   Then, the keratin fiber is immersed in a bath containing oxidizing agents such as hydrogen peroxide and monopersulfuric acid.   The oxidizing agents are  decomposed by catalytic effect of the transition metal.   Mainly due to pressure of oxygen gas evolved by the decomposition keratin layers, which are scales on the keratin fiber, are peeled off.   Thus, it is possible to remove only the keratin parts, which are not agreeable to the touch, without damaging the non-keratin protein, and to provide modified fiber which substantially contains no remaining metal.   High shrink proof effect may be achieved without using the conventional chlorine compounds as the oxidizing agents.

Abstract: Electroconductive particles comprising an electrically conductive non-metallic particle coated with an electrochromic material. Such electroconductive particles can be provided in polymeric dispersions that are useful for preparing electrically conductive, essentially ionically isolative composite layers. Composite layers (3a) can be used in laminates for electrochromic displays where an ionically conductive layer (4) is in contact with electrochromic material. By applying an electrical potential across the interface of the ionically conductive layer and the electrochromic material, an electrochromic effect can be generated. A preferred electroconductive particle comprises titanium dioxide particles coated with a layer of antimony-doped tin oxide and a layer of electrochromic material such as polyaniline or polypyrrole. In preferred dispersions and laminates the electroconductive particle is dispersed in a light transmitting polymer matrix. The materials of this invention allow for the high speed fabrication of flexible displays, e.g. by printing methods.

Abstract: A particle mat for pressing into a pressed board is heated by concurrently passing through the mat treatment air coming from an air-conditioning system and having a predetermined moisture content and dew point, heating the treatment air passing through the mat to a temperature which is greater by a dew-point differential than the dew point of the treatment air, and controlling the volume rate of flow of the treatment air and the moisture content of the treatment air such that the mat is preheated to a predetermined temperature while liquid in the treatment air is allowed to condense in the mat to at most a maximum liquid content. This preheating method reduces the processing time of the particle mat and substantially mintains or improves the properties of the mat while allowing the preheating to be carried out in an exactly controlled manner.

Title: Method for cleaning a gas flow
Inventor: PERSSON ANDERS
IPC: B01D53/06
Filed: 1994-06-29
Abstract: In the cleaning of a humid gas flow containing gaseous impurities, the gas flow is dehumidified by cooling. The cooled gas flow is reheated and then gaseous through a device (7') for the absorption of gaseous impurities.   A desorption-gas flow is heated so as to form a hot-gas flow, which is conducted through the adsorption device (7') in order to clean the latter. The contaminated hot-gas flow is conducted to a combustion device (10') in order to be burnt. Hot combustion gases are removed from the combustion device (10') in order to take part in at least one of the heating processes by being introduced into and mixed with the cooled gas flow and the desorption-gas flow.

Title: Segmented Wood Chip Cracking Roll
Inventor: BIELAGUS JOSEPH B
IPC: B02C4/30
Filed: 1994-11-08
Abstract: A wood chip cracking device (20) for use in papermaking employs closely spaced, oppositely rotating rolls (24, 26) which have pyramid-shaped projections (38) on the roll surfaces (32, 34). This chip destructuring apparatus (20) is rendered readily serviceable with minimal downtime by constructing the roll surface (32, 34) of removable segments (25) which are bolted to a central rotatable shaft (46). The segments (25) are sized so they can be lifted by a service man. As damage to the roll surface (32, 34), such as by exposure to tramp metal, is typically limited to a single segment, service and repair of the roll (24, 26) is expedited by permitting removal of a single damaged segment without removing the remaining undamaged segments (25). Each segment is bored for twelve bolts (72) and is affixed to the inner shell by twelve recessed bolts (72). The surface segments (25) allow the surface to be replaced without removing the rolls (24, 236) from the frame (30) of the wood chip cracking device (20).
