Abstract: Abstract of the Disclosure The invention relates to a process for thermally stabilis-ing and improving the dimensional stability of soft gelatin capsules containing the pharmaceutical active principle in the shell, characterized in that the capsules are provided with a film coating of a film-forming polymer which is sol-uble or swellable in water and soluble in solvent. The properties of soft gelatin capsules are improved whilst the other advantageous properties are maintained. The coat-ed gelatin capsules are, e.g., temperature-resistent and less sensitive to moisture and they do not stick together in storage containers even after prolonged storage. - 1 -

Abstract: BATTERY BACKUP CIRCUIT FOR AN INTEGRATED MEMORY DEVICE          ABSTRACT OF THE DISCLOSURE   Backup power for the volatile cells of a memory array is provided by an auxiliary backup battery power source which is automatically connected to the memory array power input node in response to loss of power from the primary external power source. Primary operating current for the volatile cells of the memory array is conducted through a first field effect transistor switch having its gate and drain electrically connected to an external power input pin and its source electrically connected to the memory array power input node. Auxiliary operating current for the volatile cells of the memory array is provided by a second field effect transistor switch having its drain and gate electrically connected to an external control signal input pin and its source electrically connected to the memory array power input node. The first transistor switch automatically establishes a conductive path fom the external power input pin to the memory array power input node in response to the voltage of the power input pin relative to the voltage of the memory array power input node rising above the threshold voltage of the transistor, and automatically interrupts the conductive path in response to the voltage of the external power input pin relative to the voltage of the memory array power input node falling below the threshold voltage. The second transistor switch automatically establishes and interrupts a conductive path from the control signal input pin to the memory array input power input node in response to the rise and fall of voltage on the control signal input pin relative to the voltage of the memory array power input node.

Title: Slip ring cooling devices for electrical rotary  machines
Inventor: OOKI NORIHIRO
IPC: H02K9/28
Filed: 1980-05-29
Granted: 1982-10-19
Abstract: Abstract of the Disclosure The invention relates to a slip ring cooling device for an electrical rotary machine.  The device includes a plurality of closed chambers in the slip ring extending axially in the peripheral portion with intervals therebetween in the peripheral direction, and an annular passage at one side.  The closed chambers each are defined by the surfaces of holes made in the slip ring so as to axially extend at the peripheral portion of the slip ring.  The axially extended holes have open ends and closed ends.   The annular passage is fluidly connected to each of the open ends so that the closed chambers communicate with the annular passage.  A volatile liquid introduced into the passage is distributed uniformly to each of the closed chambers by centrifugal force applied thereon upon the rotation of the slip ring.  The distributed liquid is evaporated by the slip ring and brushes contacting the slip ring to form a vapor.          The vapor is transferred to the lower temperature portion by the pressure difference where it is cooled and condensed, thus cooling the slip ring uniformly.  The device allows efficient cooling of the slip ring without vibrational problems or pro-truding structure.

The assembly includes a base plate rotatively mounted on the platform on each side of the coal-transporting conveyor.  A plurality of bars are carried by each base plate, each bar extending across its associated base plate intermediate the rotative axis of the base plate and the base plate periphery.  Each bar has one end adjacent the next angularly adjacent bar and has other end extending beyond the base plate periphery.  Each angularly adjacent pair of bars provide a substantially inwardly closed pocket.  More particu-larly, each bar extends across the base plate and is spaced from and intermediate the rotative axis and the base plate periphery, and extends substantially transverse to a radial line passed through the rotative axis and intermediate the ends of the bar.   Each bar includes a leading edge facing in the direction of base plate rotation and extending substantially between its ends, and includes a trailing edge facing in the opposite direction and extending outwardly from the leading edge of the next angularly adjacent bar.  The leading edge of each bar pushes the coal out-wardly onto the conveyor as the associated base plate rotates.

Abstract: ABSTRACT OF THE DISCLOSURE A nickel hydroxlde precipitated from nickel-salt solutions acquires, as an active electrode material for alkaline batteries, a highly favourable specific capacity and a reduced tendency to swelling, as a result of a special drying process which is carried out in two stages.  In the first stage, using temperatures between 40 and, at the most 80°C, the water content is reduced to a residual humidity of about 10% by weight and then final drying is carried in a second stage at temperatures between 100 and 160°C thereby greatly reduc-ing recrystallization during the first stage and not affecting the capacity of the compound during high temperature drying in the second stage.

Abstract: CURRENT LIMITER FOR SWITCHED DC-TO-DC CONVERTER   by NEALE A. ZELLMER     ABSTRACT OF THE DISCLOSURE           A switched DC-to-DC converter in a power supply is powered by input line current from an external power source and driven by voltage pulses from a variable duty cycle pulse width modulator for converting a DC input voltage to a DC supply voltage of a different value that is applied to a load impedance.          A comparator monitors the supply voltage for producing an error voltage that biases the modulator for adjusting the width of the voltage pulses, and thus the duty cycle of the converter, for maintaining the supply voltage relatively constant.  An RC circuit integrates the voltage pulses for producing an indication of the average value thereof, which is directly related to the value of line current drawn by the converter. When the average value of voltage pulses exceeds a reference voltage, the value of bias voltage is limited for establishing the maximum width of voltage pulses and duty cycle of the converter, and thereby limit the the maximum line current drawn by the power supply.

Abstract: CONTROLLABLY DEFORMED ELASTIC      WAVEGUIDE ELEMENTS             Abstract An elastic two dimensionally guiding waveguide is controllably stretched between two or more different configurations, the different configurations being such that wave energy takes different paths through the waveguide at each of the two or more different configurations.  The paths are different because wave energy which propagates along and between two parallel boundary surfaces or which follows a surface travels along a geodesic path and the geodesic path can be changed by stretchably deforming the surface shape in a suitable manner. In one embodiment an optically transparent sheet of rubber-like material is stretched into a depression or hole within a substrate using controlled pneumatic forces.  Many different active functions may be implemented using this principle, including switching, variable focussing, modulation, scanning and deflection.

Abstract: ABSTRACT OF THE DISCLOSURE      The axial shirring of thin walled inflated tubular material, especially for sausage manufacture, with a mandrel providing a radial bracing in its interior, occurs in combination with at least one air stream directed obliquely against the axis of the tubular material, wherein the air stream force is                    allowed to revolve about the said axis as the tubular material moves axially along the mandrel.  The tubular material is thereby axially compacted against a stop with formation of regular folds or "shirrings".  Shirring formation can be readily influenced by changing the air pressure.  The nozzle or nozzles is or are connected to a source of compressed air and can he directed obliquely against the mandrel axis as it or they revolve about the said mandrel axis.
