Abstract: TITLE:    TOY HAVING A SEEMINGLY RANDOM MOVEMENT      ABSTRACT         A mechanical toy which has a seemingly random movement of both its extendable parts and its motion is described.  The toy has a base to which is attached several extendable members which can be pushed into the toy by the child to a retractable position.  The extendable members are held in the retractable position by a series of independently acting holding members.  The toy includes a button which is positioned so that a child may easily push it.  On depression of the button one, several or all of the extendable members may be released from the retracted position allowing them to extend out of the toy into an extended position.  Concurrently the propulsion mechanism of the toy may or may not also be activated causing the toy to move along the surface on which it is set.  The propulsion mechanism is energized by the child mechanically depressing one of the extensions into its retracted position.

Title: Method of suspension polymerization  and apparatus therefor
Inventor: ALBRIGHT ROBERT L
IPC: C08F2/18

Granted: 1982-07-13
Abstract: Abstract A method of suspension polymerization of a monomer or monomer mixture to control average particle size and size distribution utilizing in-line static mixing as the means of forming an aqueous suspension of monomer droplets in water prior to thermal polymerization thereof.  The method is particularly adaptable to suspension polymerization of ion exchange polymer beads of relatively small size and narrow size distribution in conventional aqueous suspension media.  A preferred apparatus utilizes an in-line mixer having a plurality of adjacent corrugated stationary baffle elements and concentric inlet orifices for monomer and aqueous dis-persion media abutting the first baffle element of the mixer.

In the process, brewers' yeast is allowed to act upon a, preferably all-malt, wort until said yeast is partially developed, following which, the said adjunct is introduced into the partially fermented wort and the brewing process carried to completion.  It is highly preferable that the said adjunct is introduced into the partially fermented wort over a period of time during which the plato value of the wort is not signifi-cantly altered.  The process is especially advantageous when used to produce the alcoholic brewing beverages having reduced caloric and/or alcoholic contents.

Abstract: µ-LAW TO FLOATING POINT CONVERTER             Abstract of the Disclosure In PCM, systems, it is known to convert µ-law digital code words including a sign bit, m characteristic bits, and n mantissa representing respectively the polarity, segment value, and quantizing step of a quantized analog sample into a binary floating point representation thereof including a sign, exponent, and mantissa in order to process the digital signal.  Known converters are of two relatively expensive types: (1) using a memory having 2m+n locations or (2) employing a µ-law to fixed point conversion followed by fixed point to floating point conversion.  To mitigate such drawbacks, the present converter (100) employs a relatively inexpen-sive translator (200) for translating the segment value and a prefixed quantizing step into a reference martissa. The code word quantizing step is then added (90, 95) to the reference mantissa to provide the floating point mantissa.  The exponent is equal to the segment value; and the sign bit represents the sign.  The translator may be implemented, for example, by using a memory having 2m locations or by simple combinatorial logic.

Abstract: FEEDBACK SHAFT EXTENDING BETWEEN AND DISPLACEMENT CONTROL VALVE               Abstract of the Disclosure A hydrostatic pump unit is located within a housing which serves also as a hydraulic fluid sump.  A displacement control valve for controlling actuators for adjusting the angular position of a swashplate of the pump unit is mounted on the exterior of the housing.  Disposed along the axis about which the swashplate is adjustable and joining the swashplate to a shiftable sleeve of the control valve is a feedback shaft which acts to return the valve to a null condition when the swashplate arrives at a com-manded new displacement effecting position.  The feedback shaft has a passage extending therethrough which acts as a drain connection between the valve and the sump defined by the housing.          A check valve is located in the passage for preventing fluid from draining from the housing when the valve is disconnected from the feedback shaft for service.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention relates to a light intensity modulator, in integrated optics and an integrated optical circuit comprising such a modulator.       The modulator comprises a two-arm interferometer in which there is created by electro-optical effect, a phase shift controlled by a modula-ting voltage between the light waves propagated in the two arms. It is characterized by a feedback loop comprising a light separator placed on the output guide of the interferometer, and a photodiode collecting the fraction of output intensity from the separator and supplying an electric voltage which is superimposed in the interferometer on the modulating vol-tage.   Thus linearization of the output intensity-modulating voltage response curve is obtained.

Abstract: FURNACE FIRING RATE MODULATION USING INDUCED DRAFT BLOWER AND EXHAUST     STACK PRESSURE FEEDBACK                       Abstract Apparatus is provided for constructing an induced draft furnace and its control system, to produce an induced draft furnace having increased efficiency.  A blower located in the furnace exhaust stack is used to induce movement of air, fuel and combustion products into, through and out of the combustion chamber.  A flow-limiting orifice in the exhaust  stack in proximity to the blower causes a region of higher pressure to exist upstream from the orifice, with a region of lower pressure downstream from the orifice.  A pressure signal representative of the flow rate of exhaust stack gases is sensed on one side of the orifice and is fed back to a modulating gas valve which controls the outlet gas flow from the valve to be proportional to the magnitude of the pressure signal representing exhaust stack flow rate.  By selecting blower speeds and flow capacities, various firing rates for the furnace can be selected, from the design maximum of the furnace down to various derated levels.

Abstract: QUANTIZED SPEED CONTROL OF A STEPPER MOTOR      Abstract A coded disk is coupled to a stepper motor to control the speed of the latter.  On the periphery of the coded disk are a plurality of equidistant marks, the sensing of each of which generates a motor control pulse.  One motor control pulse produces one motor step.  Previously, motors have been decelerated by delaying the initiation of the motor control pulses. This is disadvantageous if the speed fluctations occurred prior to the initiation of a motor control pulse, in that the optimum deceleration angle of the motor could not be maintained.  In accordance with the invention, several fine marks are provided on the coded disk for each motor step and a motor control pulse is emitted only when a selected one of the fine marks has been sensed.  This leads to motor control pulses with rigid angles, and speed fluctations prior to the emission of such pulses no longer produce negative effects.  The invention is suitable for the print head control of metal paper printers.

Abstract: ABSTRACT OF THE DISCLOSURE Antineoplastic agents are rendered tumor-specific by derivatization with a peptide specifier so as to convert the antineoplastic agent into a pharmacologically  inactive pro-drug which is selectively activatible at the tumor site.  The peptide specifier has an amino acid residue sequence such that it will be selectively enzymatically cleaved from the antineoplastic agent  by tumor-associated fibrinolytic and/or blood-coagulating proteases, such as plasmin and plasminogen activator, so as to effect release of the antineoplastic agent in pharmacologically active form in the vicinity of the tumor.  These and other similar hydrolytic enzyme-activatible pro-drugs may be formed with their specifier moiety and their drug moiety covalently linked together through an intermediate self-immolative connector moiety having a molecular structure such that enzymatic cleavage of the bond covalently linking it to the specifier moiety will initiate spontaneous cleavage of the bond covalently linking it to the drug moiety to thereby effect re-lease or the drug in pharmacologically active form.
