Abstract: Abstract A  switching  element  for  self-routing,  multistage, packet-switching,  interconnection networks which comprise:   an input unit, composed of as many sections ( IMA, IMB) as there are elements  inputs,  each  section comprising  a FIFO memory  (FIFA, FIFB)  for  packet  buffering;  a  switch  (SW)  associated  with  a control unit (SCU) which, for each packet to be forwarded, sets up a requested connection for that packet between one input and one or more outputs of the element (ECP), based on a routing tag associated with each packet and comprising a first and a second portion relative to normal routing and to broadcasting  in the different stages of the network (RC), and solves possible routing conflicts between packets  simultaneously arriving  at different inputs;  and an output unit, composed of as many sections (RUO, RUl)  as there are element outputs and performing the functions necessary for correct packet  forwarding  toward  a destination. The control unit (SCU) of the switch (SW) is arranged to handle broadcasting of  a packet  independently of  all  other  elements (ECP)  in the same stage, to allow broadcasting to a number of destinations, not limited to a power of 2, (for an element with two inputs and two outputs) and cooperates with the memory (FIF) storing the packet to be broadcast in such a way that broadcast-ing does not give rise to internal blocking in the network (RC). The control unit (SCU) moreover solves routing conflicts to set an upper bound to packet residence time within the network.

Title: Process of preparing higher order cuprate complexes
Inventor: CAMPBELL ARTHUR L
IPC: C07F7/22
Filed: 1988-06-06
Granted: 1992-12-15
Abstract: ABSTRACT OF THE DISCLOSURE This invention encompasses a process for preparing higher order cuprate complexes which contain a carbanion for the formation of carbon to carbon bonds in reactions such as epoxide addition.   The complex is formed by reacting a first cuprate complex with a stannane such that the carbanion to be used to form carbon to carbon bonds is transferred from the stannane to the first cuprate complex to form a different higher order cuprate complex.  This process permits the in situ preparation of a higher order cuprate complex having the carbanion desired to be used in a synthetic reaction.   Higher order cuprate complexes derived from the reaction of a cuprate complex with 1,2-bis-tri-n-butylstannyl ethylene are particularly useful for the addition to epoxides to form  vinyl  tin  intermediates  useful  for  preparing  omega  side  chains  of prostaglandins.

Granted: 1993-02-09
Abstract: MAGNETRON WITH FULL WAVE BRIDGE INVERTER    ABSTRACT OF THE DISCLOSURE      An arrangement for providing power to a cooking magnetron uses a full wave bridge inverter circuit. Four semiconductor switches, pairs of which are switched on and off by a pulse width modulation control circuit provide power to a primary winding of a power transformer.  A secondary winding of the power transformer supplies the power to the magnetron.  The control circuit switches two of the four transistors on and off by way of an isolated drive circuit such that the control terminals of the semiconductor switches float with respect to the other two semiconductor switches.  The control circuit includes pulse width modulation circuitry which provides a control pulse having a width proportional to an input provided across a transconductance amplifier.  A signal dependent upon magnetron current is used as part of a feedback loop such that a magnetron current is stabilized against variations due to line voltage changes.

Abstract: Process for refining a triglyceride oil comprising bringing the oil into contact with at least an amount of aqueous alkali solution equal to the stoichiometric amount required to neutralise the oil, forming a soapstock and separating said soapstock and oil characterised by bringing the oil into contact with the aqueous alkali solution at a temperature in the range of from 40 to 140°C and forming at a temperature in the range of from 40 to 140°C a soapstock which contains with respect to the initial fatty acid content of the oil at least about 0.7 wt% of electrolyte and which comprises a member selected from the group comprising a single phase of neat soap, a binary phase mixture of neat soap and niger, a binary phase mixture of neat soap and lye and a ternary phase mixture of neat soap, lye and niger. Each of the niger, lye and neat soap phases is a single phase comprising water, electrolyte and soap. The lack of substantial amounts of free water reduces saponification and thus oil loss. The presence of niger and/lye can reduce the viscosity of the soapstock and hence aid its separation from the oil.
