Abstract: A honeycomb heater having integrally formed electrodes comprises a honeycomb structure having a desired honeycomb configuration,  and electrodes which are integrally formed with  the  honeycomb  structure  at  predetermined  positions thereon.  The honeycomb heater is manufactured by joining or contacting the electrode-like formed bodies to the formed honeycomb body, and then by sintering the formed honeycomb body  with  the  electrode-like  formed  bodies  attached  or contacted  thereto.   The  electrodes are made  of  the  same material as that of the honeycomb body,  or of a material having  an  electric  resistance  lower than  that  of  the material comprising the honeycomb body.  Alternatively, the honeycomb heater is manufactured by preparing an extrusion of  a  honeycomb  body as  one  body which has  a honeycomb configuration and an electrode-like shape at predetermined positions thereon, and then sintering that formed honeycomb body.

Title: Closure locking mechanisms
Inventor: DOLMAN TERRY J
IPC: E05B63/06
Filed: 1992-01-30
Abstract: ABSTRACT OF THE DISCLOSURE            A  locking  mechanism  for  a  closure  such  as  a  window comprises a body containing a gear wheel that is rotated by  a  handle.   This  rotation  is  converted  to  a  locking action  by  actuating  members  which  are  provided with  a helical thread which engages  helical  teeth on  the  gear wheel.   Rotation in one sense throws the members out of the body to perform a locking action and reverse rotation retracts  the  members  into  the  body  in  an  unlocking action.  The position of the members can be altered simply by screwing the members into and out of the body.

Abstract: In a drying process for improving the filling capacity of tobacco material, the cut and humidified tobacco material is conveyed in a stream of drying gas, dried within a tubular drying section and then separated from the drying gas. At a point where it is charged into the drying section, the drying gas has a temperature of at least 200 DEG C and a flow velocity of at least 30 m/sec. The flow velocity of the drying gas is reduced in the drying section. The flow velocity of the drying gas is in this case at most 100 m/sec at the point where it is charged into the drying section. Within the drying section, the flow velocity of the tobacco material is also reduced along with the reduction in the flow velocity of the drying gas in order to reduce the local heat transfer coefficient and the local mass transfer coefficient between the surface of the tobacco material and the surrounding drying gas. At the end of the drying section, the drying gas has a flow velocity of at most 15 m/sec and a temperature of at most 130 DEG C. <IMAGE>

Abstract: A high angle tight scattering detector using classical Rayleigh scattering. A  high intensity arc light source, filtered to leave only one wavelength illuminates a flow cell. Through he flow cell, very small, particles such as biological proteins flow in solution after separation by HPLC or some other means. A UV detector generates data regarding the weight concentration of the eluting particles and a scattered tight detector collecting scattered light at angles of approximately 90° generates a scattered light signal. The incident light intensity is also measured. The average molecular weight is then computed using the scattered and incident light data, the weight concentration data and a simplified mathematical relationship from which the size factor P and the viral coefficients have been eliminated.

Title: Protein partner screening assays and uses thereof
Inventor: KINGSTON ROBERT E
IPC: G01N33/574
Filed: 1992-10-30
Abstract: Abstract A rapid, simple and inexpensive method to screen and classify proteins as partners of dimeric proteins is described. The method utilizes fusion protein constructs containing a DNA binding domain and complementary dimerization domains from a different protein. According to the method of the invention, protein partner heterodimer formation is detected by the ability of the protein partner to displace formation of DNA binding domain homodimers, and thus reveal a phenotypic change in a bacterial host which was dependent upon maintenance of the DNA binding domain homodimer configuration. The method of the invention may further be used to identify compounds of interest which inhibit such heterodimer formation, and especially to identify compounds which prevent heterodimer formation and activation of oncogenic transcriptional regulatory proteins.
