Abstract: Abstract of she Disclosure An SSB-FDM modulator derived from a complex band-pass digital filter bank and by a filter breakdown process comprises a discrete Fourier transform (DPT) processor capable of giving phase offsets to complex output signals thereof.  In a broader sense, DFT includes inverse DFT (IDFT).  The processor is called an offset discrete Fourier transform (ODFT) processor and is supplied with real baseband sample sequences.  The phase offset complex output signals are frequency-selected by a complex band-pass digital filter unit operable at a sampling frequency for the baseband sample sequences into a real SSB-FDM signal.  An SSB-FDM demodulator likewise derived comprises a complex band-pass digital filter unit for frequency-selecting a real SSB-FDM signal into complex sample sequences of the respective baseband channels. The complex sample sequences are ODFT'ed into real baseband sample sequences. For easier processing of signals transmitted between the modulator and de-modulator, use is made of at least one dummy baseband channel.  The phase offsets may be provided in the modulator by a post-processor following a conventional DFT processor and in the demodulator by a pre-processor prior to conventional DFT.  If desired, frequency spectra of the sample sequences of a predetermined one or ones of the baseband channels may be reversed in the modulator prior to digital filtering and in the demodulator after the ODFT.

Abstract: WASTE ENERGY SOURCE UTILIZATION CIRCUIT AND METHOD                   Abstract of the Disclosure A switching circuit, typically a thyristor bridge, is connected to a source of waste energy.  The source provides d.c. power either directly or through conversion.  The switching means is also connected to an a.c. load and across a.c. power mains energizing the load. The switching circuit is operable to periodically connect the waste energy source to the a.c. load in a power supplying manner.  The a.c. mains impart suitable voltage and frequency characteristics to the electrical power so supplied.  In the event the supplied power exceeds the power required by the a.c. load, the difference is taken by the a.c. power mains.

Abstract: BRAKE ACTUATING PRESSURE PROPORTIONING SYSTEM    AND PROPORTIONER MODIFYING ARM THEREFOR        Abstract of the Disclosure A brake pressure proportioner is mounted on a sprung portion of a vehicle and is attached to an unsprung portion by means of a modifying arm.  The arm has ends pivoting on the un-sprung portion and on a proportioner control arm so that the arm maintains a constant length during relative movements of the vehicle sprung and unsprung portions, modifying the action of the brake proportioner in accordance with such movements.  The move-ments are proportional to vehicle load.  The arm provides for compression or extension without affecting the proportioner when unsprung movements between grows vehicle curb weight (no load) and gross vehicle full weight (full load) positions are exceeded in either direction.  The movement of the unsprung portion of the vehicle below the position for curb weight is known as rebound and above the curb weight position is known as jounce.  The excess jounce travel beyond the gross vehicle full weight causes the arm to compress without further modifying the proportioner.  The rebound travel of the vehicle unsprung portion permits the arm to extend without affecting the proportioner and also keeps the arm located in its proper relation with the vehicle sprung and un-sprung portions.  A modification uses a spring as the modifying arm.  The proportioner is arranged so that the spring will extend upon jounce, will maintain its effective length when unsprung movements occur between the gross vehicle curb weight and the gross vehicle full weight positions, and will decrease its effec-tive length when the unsprung movement exceeds the gross vehicle full weight position in the rebound direction.

Abstract: Azetidinones and Their Production and Use Abstract of the Disclosure Improved processes are provided for the production of a variety of azetidinones used in the partial synthesis of .beta.-lactam antibiotics.  These processes begin with chlorination of various types of anhydropenicillins to produce sulfur-free dichlorides which react with water or alcohols to produce acids or esters. These esters still contain a chlorine atom which undergoes ready intermolecular nucleophilic displacement by azide, cyanide, acetate or formate ions, or intramolecular displacement to form oxazolines, oxazolidones and oxa-anhydropenicillins.  Allylic bromination of these monocyclic and bicyclic azetidinones followed by reaction with azide ion produces an allylic azide group which can be reduced to an allylic amino group.  Most of the intermediates so produced are novel.  From these compounds there are produced new .beta.-lactam antibiotics such as 1-oxa-benzylpenicillin.
