Title: Method of preparing controlled long-acting pharmaceutical formulations in unit dosage form having uniform and comparable bioavailability characteristics
IPC: A61K9/00
Filed: 1987-03-12
Abstract: A method of preparing a multiplicity of controlled, long-acting release pharmaceutical tablets, each containing a therapeutic agent and a cellulosic ether carrier base material is shown. The method includes the steps of adding a quantity of cellulose ether base material such as hydroxypropyl methylcellulose and an active therapeutic agent to form a mixture, thoroughly and uniformly mixing that mixture, discontinuing the mixing, permitting the uniform mixture to stand for a period of time, typically two to twenty-four hours or longer, sufficient to cause the therapeutic agent to become bonded to the carrier base material and compressing portions of the mixture to form the solid unit dose tablets. The advantage of the method is that the time release of each tablet from a given batch of formulation and the time release characteristics of tablets prepared in different batches, will be substantially more uniform and comparable.

Title: Modification of plasminogen activators
Inventor: BLASI FRANCESCO
IPC: C12N9/72
Filed: 1990-04-10
Abstract: Phosphorylated plasminogen activator, such as phosphorylated pro-urokinase (pro-u-PA), which is substantially free from unphosphorylated plasminogen activator, may be obtained by phosphorylating unphosphorylated plasminogen activator with a phosphorylating enzyme or by separating phosphorylated plasminogen activator from a mixture of phosphorylated plasminogen activator and unphosphorylated plasminogen activator. Phosphorylated pro-u-PA, which is substantially free from unphosphorylated pro-u-PA, is converted by plasmin into phosphorylated u-PA. The phosphorylated plasminogen activators such as phosphorylated pro-u-PA, u-PA and t-PA are useful as thrombolytic agents.

Title: Wrap-around carrier with end restraints
Inventor: HARRIS RANDALL L
IPC: B65D71/22
Filed: 1994-06-29
Abstract: A wrap-around carrier with gusset panels connected to the bottom panel that automatically fold into their upright position when the bottom panel flaps are set up for locking engagement. The resulting upright portions of the gusset panels contact the bottom portion of adjacent articles in the carrier to prevent the articles from falling out through the ends of the carrier. The fold lines connecting the gusset panels to the side panels are angled back to lengthen these fold lines while cutouts in the gusset panels shorten the length of the other fold lines of the gusset panels. This increases the pulling power of the gusset panels while decreasing the bias force which must be overcome in order for the gusset panels to be folded into their upright position.
Patent ZA-945973-B (ZA)
Title: Method and apparatus for controlling shift force in an automated mechanical transmission
Inventor: EDELEN STEPHEN ALTON
IPC: F16H61/682
Filed: 1994-08-09
Abstract: The shift quality of an automated mechanical transmission (10) is improved and transmission wear is reduced by controlling the armature current of the motor driving the transmission shifting mechanism (22). The current is monitored by a microcontroller (16) to determine if the shifting mechanism has encountered a snag or has stalled during a shift operation. The microcontroller (16) is programmed to control the duty cycle of a pulse width modulated (PWM) voltage signal, applied to the motor, in accordance with an algorithm which provides both proportional and derivative control of the error between the measured current and a target current. The rapid reduction in current spikes through PWM control reduces the force applied to the shifting mechanism (22) and thus the sliding clutch and transmission gearing. <IMAGE>

Abstract: A closure assembly for a shipping and storage drum 22, the drum having an internally threaded plastic outlet 21 for receipt of the closure assembly. The closure assembly comprises a plastic closure 20 having an exterior end which remains outside of the internally threaded outlet 21 and opposite thereto an inserted end which extends into said threaded outlet 21 when said closure is received by the storage drum 22. The closure 20 is formed as an integral one-piece member and includes an externally threaded, generally cylindrical main body portion 40 and an outwardly radiating annular flange 43 adjacent the exterior end and being disposed at one end of said main body portion 40. The flange 43 is formed with and defines a three-sided, annular groove 44 opening towards the inserted end. The groove 44 includes a top axial wall 52, an outer inclined sidewall 54 and an inner, cylindrical sidewall 53. An annular elastomeric gasket 61 has an inside cylindrical surface 62 and is assembled into the groove 44 so as to be encapsulated between the sides of the groove. The gasket 61 is held in position by sizing the cylindrical sidewall 53 larger than the cylindrical surface 62 thereby causing the gasket 61 to stretch in order to fit around the cylindrical sidewall 53. <IMAGE>

Title: Paging receiver
Inventor: SHIMIZU EISAKU
IPC: G04G5/00
Filed: 1991-06-07
Granted: 1994-07-27
Abstract: A receiver is provided to receive at least a first call number with accompanying message information and a second call number with accompanying common information (e.g. time, weather, stock quotes). The power is supplied to the wireless section of the selective call receiver only for the time period during which information associated with each call number is received. Further, the second call number is common to all receivers and may be received each time the first call number is received. To reduce the consumption of the power supply, the receiver is provided with an execution control signal which may be selectively operated either manually or automatically to control the reception of the second call number. When the second call number is not received or when information is not transmitted in time slots allocated for that purpose, a reduction in the consumption of the power supply is attained.
