Abstract: TITLE                  INDUCED NUCLEAR BETA DECAY                           ABSTRACT      Certain nuclear beta decay transitions, normally inhibited by angular momentum or parity considerations, can be induced to occur by the application of an electromagnetic field.  The energy released by these induced nuclear transitions is useful for the controlled  production  of  power.   These  induced  beta  decay transitions are also useful to reduce the halflives of long-lived fission  product  wastes  from  nuclear  fission  power  plants.          Theoretical results are given for induced beta decay halflives as a function of the intensity of the applied field.  The nuclides treated are  all  those  found in Nature which are potentially useful  energy  sources,  as  well  as  90Sr  and 137Cs--the most radioactive of fission wastes.  It is shown that electromagnetic fields of the type and intensity required to achieve useful power production and/or fission waste disposal can be produced in a practical way.

Abstract: INTERFERENCE CANCELLATION  METHOD AND AP PA RATUS            Abstract Weighted sums of samples of an interference-corrupted data signal are generated to form phase-compensated, symbol-spaced samples.  The interference-corrupted signal is at the same time subjected to conventional adaptive equalization and is otherwise processed so as to form tentative decisions as to the transmitted data.  Cancellation signals representing the interference components of the phase-compensated samples are generated by forming respective weighted sums of the tentative decisions and each cancellation signal is combined with a respective phase-compensated sample to provide cancelled samples from which final data decisions are made.  The weighting coefficients used to form the phase-compensated samples and the cancellation signals are adaptively updated in response to error signals derived from the difference between each cancelled sample and the corresponding final decision.

The handle mounts a lever mechanism (12) which is operatively connected to the ratchet drive (3) by a plunger (4), a gear mechanism (7) and a flexible member (8).  When the lever mechanism (12) is operated linear movement of the plunger (4) translates through the gear mechanism (7)  and the flexible member (8) into rotary motion of the ratchet drive (3).  With the lever mechanism (12) removed the ratchet tool can be used as a conventional ratchet.

Abstract: ABSTRACT      Penicillin sulfoxide esters are reacted with an iso-cyanate to produce the corresponding (substituted)-2-carbamoyl-oxymethylpenam, The corresponding (substituted)-3-carbamoyl-oxycepham or the corresponding 3-methylcephem.  The 6- or 7-side-chain of these products may be cleaved to give the corresponding 6-amino (penams) or 7-amino (cephams and cephems) compounds, and the latter may be reacylated to produce different 6-acyl-2-carbamoyloxymethyl penams, 7-acyl-3-carbamoyloxy cephams and 7-acyl-3-mothylcephams.  The substituent groups may be removed from the (substituted)-2-carbamoyloxypenams or the (substituted)-3-carbamoyloxycephams to give the corresponding free 2-carbamoyloxymethylpenams or 3-carbamoyloxycephams, respectively.  Novel penams and cephams provided by the present invention (after removal of the carboxyl-protecting group to produce the free acid) are active against various Gram-positive and Gram-negative organisms and, accordingly, are useful antibacterial agents for the treatment of diseases caused by such organisms in animals, including man.

An aqueous suspension of slag particles obtained as a by-product in a coal gasification process is very difficult to dewater as such.  By dividing such a suspension in three separate fractions and applying the most appropriate dewatering method for each fraction, this difficulty is obviated.

Abstract: ABSTRACT         In the field of security validators, slot acceptors have been known which transport paper of-fered as a valid security past a testing station. Previously known acceptors have been susceptible to defeat by mosaics, stringing, shocking, photocopy duplication, and the like.  Additionally, known ac-ceptors have operated in an analog mode, relying up-on rudimentary test functions.  The invention herein overcomes the problems of the prior art by present-ing an acceptor having a note path (18) characterized by changes of direction (22,24), and which is secured at each end by means of unique gate assemblies (78, 98).  A plurality of sensors (148-152) are positioned along the note path and are controlled to take a mul-titude of data samples from the paper as it passes along the path.  The data is digitized (236) and used for solving complex transforms, the results of which are compared against results obtained from known valid securities to determine the authenticity of the paper offered.  Further, the system includes a unique anti-jamming technique of drive motor reversals, and an escrow feature which secures the paper once it has been determined to be authentic and before a vend has been made.  Yet further, there is included a novel receptacle for receipt and return of paper offered to the acceptor, and a number of variations of anti-stringing devices (112,114,118,130) which may be operatively positioned at the end of the note path.

Abstract: LATE MASK PROCESS FOR PROGRAMMING         READ ONLY MEMORIES    Tarsaim Batra ABSTRACT      A late mask programming process is provided for factory programmed ROMs or logic circuitry.  MOS transis-tors functioning as ROM cells or in logic circuitry are fabricated by a standard MOS Process.  Then, a thin stop layer of silicon nitride is provided over the transistors followed by a layer of silicon dioxide.  Programming is accomplished by applying a program mask and etching through the layers overlying the gate regions of selected transis-tors down to the silicon nitride stop layer.  The silicon nitride stop layer prevents overetching and shorting of the gates.  Then, ions are implanted underneath the gates of the selected MOS transistors to alter their threshold so,  for example,  as ROM cells they signify a different state than those cells whose transistor gates are not implanted with ions.  The silicon nitride layer serves to stop the etch solution but permits the ions to pass through, penetrate the substrate and raise the thresholds of the selected transistors.  The silicon dioxide layer stops the ions from being implanted into the nonselected transistors.

Abstract: INK JET PRINTER AND METHOD OF START-UP          AND SHUTDOWN THEREOF                 Abstract of the Disclosure An ink jet printer includes a print head means for producing at least one jet drop stream from a fluid filament emerging therefrom, and charge electrode means for inducing electrical charges on drops formed from the fluid filament.  The charge electrode means is movable into and out of an operating position in which it is adjacent and at least partially surrounds the fluid filament.  A deflection field is established prior to start-up in which the field has a non-zero electrical potential in the region of the fluid filament.  At start-up and shutdown of the printer, the charge electrode means is retracted from its normal operating position and drops are charged by the deflection field.  As a consequence, the charge electrodes are not contaminated by ink from the unstable jets.  The drops in the jet drop streams are, however, charged and deflected to a catcher by the deflection field.  After stable operation is obtained, the charge electrode means is moved into its normal operating position.  At shutdown of the printer, this sequence of steps is reversed.
