Title: Process for the lowering of the oxidation state of metal salts
Inventor: GLEIM ROBERT DAVID
IPC: C01G55/00
Filed: 1982-05-28
Abstract: The oxidation state of metal salts is lowered by contacting a solution of the salt with polyacetylene in the presence of sufficient moisture to leave the polyacetylene substantially undoped. The metal salt must have a reductive capacity of at least +0.5. This process can be used to reduce metal salts to zero active valency metal. The moisture is effectively added by treating an aqueous solution of the salt, optionally with organic cosolvent. The zero valency metal can subsequently be recovered from the polyacetylene, for example by burning the polyacetylene off.

Inventor: HEWLITT ROBERT WILLIAM
IPC: F02F1/38
Filed: 1984-06-07
Abstract: A load carrying assembly is disclosed for an internal combustion engine. The engine includes an engine block having a cylinder formed therein and having a cylinder head mounted onto the block. The cylinder head has a deck surface which closes off one end of the cylinder. A piston is reciprocally mounted in the cylinder and cooperates with the deck surface to form a combustion chamber. Air and combustion gases enter and exit the combustion chamber through intake and exhaust passages formed in the cylinder head and which terminate into intake and exhaust ports formed in the deck surface. The outer peripheries of the adjacent intake and exhaust ports form a bridge section therebetween having a maximum length which is less than twice the diameter of the larger of the intake and exhaust ports. Formed at least partially within the bridge section is a nozzle bore which also communicates with the combustion chamber. A sleeve having an enlarged portion on its outside diameter, is permanently fixed within the cylinder head such that one end will be aligned approximately adjacent to the deck surface of the cylinder head. The sleeve serves as a load carrying member which reduces the initiation of thermal cracks in the bridge section between the outer circumference of the nozzle bore and the outer peripheries of the intake and exhaust ports, respectively.

Title: Method of preparing tissue samples
Inventor: MALLUCHE HARTMUT H
IPC: B05D3/06
Filed: 1986-07-03
Abstract: A method is described for preparing tissue samples for use in diagnostic evaluation involving the rapid fixation, dehydration, and embedding of a tissue sample as well as rapid mounting of plastic sections to glass slides, dissolution of plastic and optimal staining of tissure components. The rapid and controllable fixation and the dehydration of the tissue sample utilizes the denaturing effects of microwaves on the proteins in combination with a heat sink. Alternatively, the dehydration of the tissue sample utilizes the principles of freeze drying. The tissue sample can be embedded using conventional paraffin embedding or plastic embedding techniques. Rapid penetration of plastic into the tissue is facilitated by microwaves, adhesion of plastic sections to glass slides is promoted by microwaves, as is the fast and optimal staining of tissue components. The method of this invention provides a very rapid technique for processing of tissue for diagnostic and analytic evaluation.

Title: Method and apparatus for automatically identifying a program including a sound signal
Inventor: FARDEAU MICHEL
IPC: H04H20/31
Filed: 1992-09-24
Abstract: A method and apparatus for automatically identifying a program broadcast by a radio station or by a television channel, or recorded on a medium, by adding an inaudible encoded message to the sound signal of the program, the message identifying the broadcasting channel or station, the program, and/or the exact date. In one embodiment the sound signal is transmitted via an analog-to-digital converter to a data processor enabling frequency components to be split up, enabling the energy in some of the frequency components to be altered in a predetermined manner to form an encoded identification message, and with the output from the data processor being connected via a digital-to-analog converter to an audio output for broadcasting or recording the sound signal. In another embodiment, an analog bandpass filter is employed to separate a band of frequencies from the sound signal so that energy in the separated band may be thus altered to encode the sound signal. The invention is particularly applicable to measuring the audiences of programs that are broadcast by radio or television, or that are recorded.

Title: High speed signaling for interfacing VLSI CMOS circuits
Inventor: EJAZ UL HAQ
IPC: G06F3/00
Filed: 1999-03-08
Granted: 2003-06-04
Abstract: A system of the present invention uses small swing differential source synchronous voltage and timing reference (SSVTR and /SSVTR) signals to compare single-ended signals of the same slew rate generated at the same time from the same integrated circuit for high frequency signaling. The SSVTR and /SSVTR signals toggle every time the valid signals are driven by the transmitting integrated circuit. Each signal receiver includes two comparators, one for comparing the signal against SSVTR and the other for comparing the signal against /SSVTR. A present signal binary value determines which comparator is coupled to the receiver output, optionally by using XOR logic with SSVTR and /SSVTR. The coupled comparator in the receiver detects whether change in signal binary value occurred or not until SSVTR and /SSVTR have changed their binary value. The same comparator is coupled if the signal transitions. The comparator is decoupled if no transition occurs. When the flight time between a master device and a slave device is greater than the cycle time of the system clock, the system uses multiple clocks. One clock controls transmitting signals from the slave devices to the master device, and another clock controls initiating each slave device to communicate signals to the master device. A first clock may be looped back to the slave devices to communicate signals such as requests from the master device to the slave device.

Title: Transmission system
IPC: H04B10/213
Filed: 1979-08-17
Granted: 1982-07-21
Abstract: In a closed-loop data transmission system, the terminals 1-6 of the system each send round the loop a message formed by service data and a random bit stream. Each such message is sent in a time position in a time division cycle individual to that terminal. When such a message reaches a terminal with a data message to be sent to the originating terminal that data message is encoded into the random bit stream: the now-encoded message continues round the loop in the same direction until it reaches the originating terminal where it is received and decoded. To improve system security, in addition to the links which interconnect adjacent terminals in the loop there are so-called leap-frog links each of which extends from one terminal to the next but one terminal in the loop. The invention is described in its application to a system in which the links are optical fibre cables, but the invention is also applicable where the links are of the metallic wire type. <IMAGE>
