Title: Mixing and metering push button
Inventor: DE ROSA DANIEL
IPC: B05B11/00
Filed: 1990-11-05
Abstract: A B S T R A C T      A hand driven device for mixing and dispensing two liquids contained in two juxtaposed independent portable receptacles, mixing taking place simultaneously with dispensing, dispensing being by means of two pumps mounted in respective ones of the two receptacles, each pump including an actuator rod which causes liquid to be expelled from the receptacle when depressed, said pumps being actuatable together by means of a single pushbutton suitable for fitting on both actuator rods of said pumps simultaneously in order to bear against the ends of said rods so as to cause two quantities of liquid to be expelled simultaneously, one from each receptacle, the device being wherein the pushbutton is mounted on the rods together with adjustable axial clearance relative to the end of at least one of the rods.  A rotary spacer carries cams.  By rotating the spacer, a particular cam is placed facing the actuator rod of the pump, thereby selecting the extent to which the actuator rod is depressed and thus enabling the quantity of liquid expelled by one of the pumps to be adjusted relative to the quantity expelled by the other pump.

Abstract: A packet exchange network comprises a plurality of packet exchange nodes connected through trunk lines and terminals connected to the packet exchange nodes each of which is provided a packet storage buffer for storing re-ceived packets.  When the buffer cannot store every incoming packets due to "traffic congestion", some of the packets are discarded from the buffer by examining and registering the number of relay packet exchange nodes through which the packet passes during the communication at the time of set-ting a call to start a packet communication and by positive-ly changing a discard rate of packets to be discarded at each relay packet exchange node on the basis of the regis-tered packet exchange node number, so that all the packets have substantially the same discard rate regardless of the relay packet exchange node number.

Title: Method and Apparatus for Computing Arithmetic Expressions Using On-Line Operands and Bit-Serial Processing
Inventor: ORSINO FRANCESCO
IPC: G06F7/544
Filed: 1990-12-28
Abstract: Method and apparatus for processing on-line operands A, B and C to produce the arithmetic expression S = (A x B) + C.  In general, the apparatus comprises an input processing unit, an on-line multiplication unit, and an on-line serial addition unit.  The input processing unit is for sequentially introducing the digits of operands A, B and C into the apparatus, where each digit is represented in a redundant binary number format.  The multiplication means multiplies the sequence of digits of the operands A and B to produce the n-th product digit Pn of the product P = A x B, with the most significant digit Po being computed first.  The on-line addition unit adds the n-th product digit to the n-th digit of on-line operand C, so as to produce the n-th digit Sn of the arithmetic expression S = (A x B) + C, with the most significant digit So being produced first.  In one embodiment, the input processing unit comprises a selective conversion subunit for selectively converting the digits of operands A, B and C sequentially entering the computational device, so that each digit is represented in a redundant number format.  In such an embodiment, the redundant binary number format is characterized by signed digit numbers, and the selective conversion subunit comprises a binary-to-signed digit converter.  Also, the input processing unit preferably includes a word-length control subunit for restraining the word length of the operands and intermediate words to a predetermined limit. In yet another embodiment, the apparatus hereof includes an arithmetic performance testing system for determining whether or not the arithmetic processor is functioning properly.

Abstract: FLUFF-TYPE ORGANIC INSULATING PULP AND METHOD   OF FABRICATION AND APPLICATION                        Abstract of the Disclosure An insulating pulp for insulating buildings and other type structures and wherein the pulp is formed of organic fibers having a fiber length of from about 1.0 mm to  3  mm.    Such  pulp  is   obtained  by   a  chemi-thermomechanical  pulping  process  and  the pulp may be supplied in fluff form or compressed sheet form which is later defibrillized.    A fire retardant additive and a corrosive buffing agent is added to the pulp.    A major characteristic of such insulating pulp is that it has a density in the range of from about 0.7 to 2.0 lbs/ft3 and has an excellent thermal insulation value of about R3 to R4 per inch.   The chemi-thermomechanical wood pulp is produced from debarked trees which are primarily black spruce which have these long and strong fibers.  The pulp is  applied  by  injecting  it  through  a compressed  air conduit and at the same time an adhesive is injected in the  pulp  to  form  a binding  agent.  Because of  the property of the fibers and the fiber distribution in the fluff,   the  pulp  is  also  an  excellent  acoustical insulator.
