Title: Forming apertures in moving articles
Inventor: WOOLCOTT DEREK FREDERICK JOHN
IPC: B29C69/00
Filed: 1992-10-17
Abstract: The apparatus for routing apertures in an extruded profile, as it is extruded, comprises upper and lower supports (6, 8) which move longitudinally with the profile (4) for a certain distance and can be moved into and out of clamping engagement with it. A routing assembly (2) initially moves longitudinally with the supports (6, 8), at the same speed as the profile, and the clamped profile is raised by the moving supports into engagement with the routers (12) of the assembly (2) so that they form apertures in the profile. The routing assembly (2) is then advanced relatively to the moving supports to form elongate slots in the profile, whereafter the supports (6, 8) lower the profile out of engagement with the routers. The supports then disengage from the profile and, with the routing assembly, return to their initial position, ready to form the next series of slots in the profile. <IMAGE>

Patent GB-939492-A (GB)
Abstract: 939,492. Surveying instruments; sighting telescopes. CARL ZEISS-STIFTUNG [trading as C. ZEISS [Firm of]]. Dec. 6, 1960 [Dec. 8, 1959,], No. 41862/60. Classes 97 (1) and 97 (2). When sighting over rivers or valleys it is not possible to place the sighting level midway between two targets and thus cancel out errors due to lack of horizontality of the sighting line and accordingly two identical automatic levels are placed side by side on a common baseplate which is approximately level, the two levels facing each other so that they can be brought into reciprocal collimation by turning and tilting the instruments until the centres of the graticules in both instruments coincide. The instruments which are at 25, Fig. 2, are then rotated about their vertical axes until they both face towards the target M and if the sighting lines of each instrument are not accurately horizontal, i.e. along line 22, they will deviate on either side by equal amounts x so that by taking the average of points 35, 36 on the target M the accurate height of line 22 above the base 33 of the target is obtained. Since, however, at long distances it is difficult to read such intercepts, sighting by both instruments is taken on two distinct points m, n, lying on either side of line 22 and in the Specification equations are derived for obtaining the height H therefrom. To avoid repositioning the instruments for sighting points above and below the horizontal, an attachment 11, Fig. 3, is mounted on the objective end 12 of each instrument. A prism 13 is fixed in a member 40, provided with a scale 15 visible through window 16, and rotated by a bevel gear 10, 41. A fixed prism 18 compensates for error caused by inclination of the instrument transversely of the optical axis.

Title: Purging non-condensible gases from a refrigeration unit
Inventor: STIE KENNETH EARL
IPC: F25B43/04
Filed: 1994-03-14
Abstract: The presence of an undesirable quantity of noncondensible gases in a refrigeration unit is inferred as a function of both the vapour pressure (44) and temperature (40) at a selected point in the refrigeration unit where the noncondensible gases tend to gather, e.g. the accumulator (16). Purging of these noncondensible gases, which contaminate the refrigerant, via the valve 36 is responsive to a comparison in a programmable controller (50) of the actual vapour pressure measured at the selected point, and the known pressure of uncontaminated refrigerant at the temperature existing at the selected point. <IMAGE>

Downstream of the sealing stations 40 the film 14 passes through coolers 46, 48 for cooling the seals. The film layer is or film layers are cut longitudinally to provide a bag inlet opening in the film 40 extending between each adjacent pair of seals prior to delivering the film 14 to a guillotine 53. At the guillotine 53 the film is cut transversely across each seal to part individual bags away from a leading end of the film 14. <IMAGE>

Abstract: A method for growing a thin InGaAs or InAlAs layer (4) with a heavy lattice mismatch on a GaAs substrate (1) by a MOCVD process comprises injecting a first material gas by a MOCVD process to grow a buffer layer (2) on a GaAs substrate to a prescribed thickness. After stopping the injection of the first material gas for a few seconds, a second material gas containing a Group III element is injected at a prescribed temperature. A third material gas containing a Group V element is then injected to grow, on the buffer layer, a thin metallic layer (3) of a binary compound containing the Group III element of a high concentration to a thickness of 2nm or less. After a prescribed time from the injection of the third material gas, In and Ga gases or In and Al gases, mixed in the prescribed proportion are injected in an atmosphere of said third material gas to grow a thin InGaAs or InAlAs semiconductor layer on the thin metallic layer. Lattice mismatch exists between the semiconductor layer and the substrate. <IMAGE>

Title: Nasal drug delivery composition containing nicotine
Inventor: ILLUM LISBETH
IPC: A61K47/48
Filed: 1994-05-20
Abstract: The present invention provides a nasal drug delivery composition comprising nicotine or a pharmacologically-acceptable salt or derivative thereof wherein the composition is adapted to delivery a pulse of nicotine for rapid absorption and a controlled release of nicotine for subsequent sustained absorption. The controlled release phase can be achieved by providing an ion-exchange material which will form a complex with the nicotine. The ion-exchange material may be a polymeric material such as a polysaccharide, or may be in the form of bioadhesive ion-exchange microspheres. The pulse release can be achieved by overloading the ion-exchange material with nicotine so that the composition contains some excess nicotine for immediate release and absorption. Alternatively, some nicotine may be associated with a non ion-exchange material which will release the nicotine immediately on contact with the nasal mucosa, for example non ion-exchange bioadhesive microspheres. <IMAGE>
