Title: Filter crusher
Inventor: STEPHENSON DALE
IPC: B30B9/04
Filed: 1991-08-20
Abstract: ABSTRACT OF THE DISCLOSURE            FILTER CRUSHER     A crushing device for use with used oil filters comprises a housing defining an anvil plate at one end of the housing.  A ram is positioned within the housing and includes a ram  plate  movable  toward  the  anvil  to  compress  the  filter therebetween.   The  filter  is of the type including a filter material within an outside casing and a sealing ring at one end of the outside casing surrounding the openings through which the oil flow normally occurs.   The anvil plate is smooth and flat except for a substantially central opening so that the oil expressed from the filter as it is crushed is carefully passed through   the   opening   for   collection.     Confining   walls surrounding  the  filter when  in position on the anvil ensure that the opening in the anvil is maintained within the bounds of the sealing ring.  A safety door is positioned on the front face of the housing and can be moved manually to expose the crushing chamber.

Title: Process for the liquid-phase preparation of nitriles from aliphatic dicarboxylic acids
Inventor: SCHMITZ KARL
IPC: B01J20/14
Filed: 1991-12-13
Abstract: ABSTRACT             A process for the liquid-phase preparation of nitrile from an aliphatic dicarboxylic acid, by reacting the dicarboxylic acid with ammonia at a temperature of from about 200 to about 350°C, in the presence of a catalyst selected from the group consisting of phosphoric acid, metaphosphoric acid, poly-phosphoric acid, mixtures and ammonium salts thereof.  The process is further characterised in that an adsorbant for the catalyst is added to the reaction mixture.  Suitable adsorbants are filter-ing aids based on kieselguhr and Tonsil bleaching earth.  The addition of adsorbant prevents the formation of deposits of poly-phosphoric acid on the reactor walls, which deposits impair the heat exchange and cause corrosion.  The catalyst system compris-ing adsorbant and phosphoric acid can be easily separated off and reused  for the next batch.

Title: Shaft grounding brush and holder
Inventor: TWERDOCHLIB MICHAEL
IPC: H01R39/38
Filed: 1992-02-28
Abstract: W.E. Case 56,081 Abstract of the Disclosure A brush assembly for providing contact between a grounding brush and a rotating shaft, in which the non-contact time associated with brush bounce is reduced. A brush is provided which is fixed to a pivotable arm, with a bias force applied to the arm, such that when the brush is bounced from a shaft as a result of vibration or shaft wobbling, the bias force will reestablish contact between the brush and shaft. Rolling contact between a negator spring and the arm is also provided for reducing friction associated with contact between the spring and pivotable arm.  Due to the reduced friction provided by the rolling contact, and more significantly by the pivotal mounting of the arm to which the brush is fixed, the response of the assembly in reestablishing contact with the shaft is greatly improved.

Title: Direct spray-dried drug/lipid powder composition
Inventor: DURRANI MANZER
IPC: A61K9/127
Filed: 1991-05-06
Abstract: The present invention discloses a method for direct spray-drying a solution of lipids and water soluble drug to generate a bulk powder as an alternative to the drying of preformed liposomes. In the present method the lipids are dissolved in a solvent and the water-soluble drug is dissolved in aqueous solvent. The two solutions are combined to form a precipitate-free feed solution which is then spray-dried to generate the bulk powder. Upon rehydration the powder spontaneously forms liposomes having a high drug encapsulation efficiency of approximately 70 %. The direct spray-dried powder is particularly useful for drug administration by inhalation.

Title: Laser beam guidance device for civil engineering/earthmoving plant
Inventor: GAFFARD JEAN-PAUL
IPC: E01C19/00
Filed: 1992-10-30
Abstract: ABSTRACT OF THE DISCLOSURE A device   for   guiding a   civil   engineering/ earthmoving machine using laser beams comprises a laser emitter  and  two  laser  receivers  each  mounted  on  a displacement unit mobile with two degrees  of  freedom. Two receiver position sensors are associated with each unit  to  measure  its  position  with  reference  to  two degrees of freedom and to generate signals representative of this position.  A machine position sensor measures the position of the machine with reference to a fifth degree of  freedom  and  generates  a  signal  representing  this position.  A computer responsive to these signals stores the geometrical features of the surface over which the machine  is  guided  and  controls  each  receiver  in  two dimensions to maintain it centered on the beam from the laser emitter.  The computer also generates in real time command instructions applied to actuators controlling the machine, on the basis of these geometrical features.
