Inventor: POWELL DAVID R
IPC: A61K9/22
Filed: 1984-07-06
Abstract: A new class of solid pharmaceutical formulations enables the attainment of slow, zero order in vivo release of a wide range of pharmaceutically active ingredients upon oral administration. A broad range of release rates can be preselected by suitable adjustments of tablet properties. The formulations are based upon control of active ingredient release from the surface of the tablet via a controlled surface erosion mechanism. These compositions comprise:(a) an effective amount in the range of 10-90 wt. % of a pharmacologically active compound having a water solubility (20' C.) of 1/5-1/1000 (w/w);(b) 1-40 wt. % of a compound which is pharmaceutically acceptable in oral compositions and has a water solubility (20° C.) of 1/1-1/40 (w/w);(c) 2-20 wt. % of a compound which is pharmaceutically acceptable in oral compositions and has a water solubility (20° C.) of 1/1-1/10 (w/w);(d) an amount in the range of 0.05-1.0 wt. % of a disintegrating agent for pharmaceutical compositions, at which amount the compound is ineffective as a disintegrating agent;(e) 0.1-2.0wt.. % of a surfactant which is pharmaceutically acceptable in oral compositions; and, as necessary for tablet manufacturing purposes;(f) 1-20 wt. % of a binder which is pharmaceutically acceptable in oral compositions; or(g) 0.5-5.0 wt. % of a die wall lubricant which is pharmaceutically acceptable in oral compositions.

Abstract: A method of and apparatus for the manufacture of metal extrusions is disclosed in which the metal is extruded through a die having, preferably, a single extrusion aperture. The leading end of the extruded section is gripped and pulled sway from the die by a puller 11, and the section is at the same time rapidly and uniformly cooled in a tunnel 8 as extrusion proceeds. When the puller reaches a predetermined distance from the die, the puller and extrusion are stopped simultaneously. The extruded section is then gripped in a device 12 including a pair of gripping jaws adjacent the die and shearing means by which the section is cut through at a location between this pair of jaws and the die. The puller is then operated to move it to stretch the extruded section while the section remains gripped by the gripping jaws of device 12 and in alignment with the die.

Abstract: Twin axle drive or connection of two twin axle drives which save on overall height and mass in the short powerflux of the perpendicular loading and ensure, when travelling in a tight bend in the track, the necessary rotation angle with an acceptable rotation resistance and ensure transverse play better than a link suspension. According to the invention, the object is achieved in that the leaf springs (10) are coupled at their ends to the wagon stays to the side of the lateral members (3). A support pendulum (14) is supported on the spring collar (11) of the leaf springs (10) and rolls with the necessary resistance in the longitudinal direction of the vehicle without restoring force and thus brings about the necessary restriction on rotation. In the transverse direction, the restoring force and transverse restriction required for transverse play is produced by the design of the crowned rolling segment of the support pendulum (14). In the connection of two twin axle units, steering is effected by a Beugniot lever. Both axle units are connected to a transverse coupling. The invention is preferably suitable for use with low-level wagons (1) with a continuous floor height and small wheels. <IMAGE>

Abstract: A telephone system uses above voice-band ASK control and supervisory signals which are appended to digitally encoded voice by forcing the least significant bits to a selected level for transmission to the receiving end. At the receiving end, the ASK is regenerated by a circuit including special filter and a pulse generator. To eliminate audible noise resulting from the filter action, the ASK signal or the pulses from the pulse generator is shifted in phase by about 90° before application to a filter.      The result is significantly reduced noise.

Abstract: Reflective tape  for  pinstriping  of  automobiles  or  other vehicles. The tape has strips of retroreflective material sandwiched between a bottom release liner of polyethylene coated paper and a clear top release liner having an adhesive undersurface for retaining the tape composite intact with the strips parallel one another  prior  to  and  during  application  to  a  vehicle.  The retroreflective material  is highly visible at night for safety.          The strips include  pressure-sensitive adhesive. When the tape is applied to a vehicle, thin pinstripes of retroreflective material are seen. The material may be colored to contrast with the color of the vehicle paint,  which is visible on either side of the tape and also through the open middle section between the pinstripes of retroreflective material.  The strips are applied by peeling away the bottom liner as the top liner and strips are applied to a surface; thereafter, the top release liner is peeled away leaving only the two retroreflective material strips on the surface.  The tape is made by sandwiching the strips between the bottom and top release liners.

Abstract: A heating sensor is disposed within the pipe wherein a clearance defined between inner wall of the measuring pipe and outer surface of the heating sensor is dimensioned so that the measurement may be free from any influence of a connective heat transfer. Temperatures of the fluid and the heating sensor are measured and a differential temperature therebetween in the steady state is determined. A correlation established between the differential temperature and a thermal conductivity of the fluid is utilized to obtain the thermal conductivity of this fluid.      Alternatively, the differential temperature between the fluid being measured and the heating sensor may be controlled at a constant value and a correlation between a heating value of the heating sensor and the thermal conductivity of the fluid may be utilized to determine the thermal conductivity of this fluid based on an actual heating value of the heating sensor.      A temperature of the fluid staying within the measuring pipe can be controlled by thermostatic means.      The said clearance may be provided by, the heating sensor and the movable spacer adapted to maintain a predetermined gap with respect to outer surface of said heating sensor.
