Title: An adhesive system for bonding uncured rubber to cured polyurethane
IPC: C08L75/04
Filed: 1989-08-29
Abstract: An adhesive system for bonding an uncured 
rubber to a cured polyurethane comprises a nitroso type 
crosslinking agent, a polyisocyanate crosslinking agent, 
a wetting agent such as an epoxy resin which is capable 
of wetting the polyurethane, and optionally a solvent. A 
tackifier can optionally be contained in the above adhe­
sive system to improve tack in situations where such is 
desired. The adhesive system can be utilized in specific 
situations such as to adhere a steel bead, as in a tire, 
which is encapsulated in polyurethane, with a tire side­
wall, to adhere an uncured rubber tread to a urethane 
tire, to adhere a tread or repair patch over sections of 
a cured polyurethane, and the like.

Title: Modified carboxylated polyamide compositions
IPC: C09D11/10
Filed: 1989-09-21
Abstract: New modified carboxylated polyamide compositions are obtainable by fusing 
a mixture of a polyamide of the type usable for printing inks (A) and an 
carboxylated resin and/or carboxylated polymer and in particular mixtures 
thereof, such as a maleated rosin and an acrylic acid or methacrylic acid 
copolymer at a temperature of 180-250°C. In the preferred process the 
modified carboxylated polyamide compositions are synthesized in a two-step 
process in which the polyamide is first condensed (fused) with a 
carboxylated rosin and this intermediate product is then further condensed 
(fused) with an copolymer of an olefinically unsaturated acid having 
3-5 C-atoms being soluble in an aqueous alkaline solvent. The resulting 
compositions can be used in water or solvent ink systems having improved 
properties.

Title: Method and device for clamping instable parts
IPC: B23Q3/08
Filed: 1989-12-11
Abstract: A method and a device for clamping plane instable parts for subsequent machining are proposed. Here, the workpiece to be machined is secured radially and axially against the bearing surface of the clamping device and, after its radial centring on the surface remote from the surface to be machined, is supported at a multiplicity of locations over a minimum area or in a point-like manner. In this axially supported position of the workpiece, a tensile force is applied in the direction of the clamping device in order to fix the workpiece at at least one surface section of small area. The clamping device has axially movable bolts and devices acting over a small area for applying tensile force to the surface remote from the workpiece surface to be machined. During the machining of the workpiece, the bolts, each covered by the workpiece, are placed against the surface for the purpose of support and are fixed in this positive-locking position, while a tension means for axially fixing the workpiece is in engagement with the latter. <IMAGE>

Patent EP-0418457-A3 (EP)
Title: Pipelined error checking and correction for cache memories
IPC: G06F12/08
Filed: 1990-03-20
Abstract: A scheme for the implementation of single error correction, double error detection function is provided for cache memories wherein the normal cache access time is not affected by the addition of the ECC function. Check bits are provided for multiple bytes of data, thereby lowering the overhead of the error detecting and correcting technique. When a single error is detected, a cycle is inserted by the control circuitry of the cache chip. At the same time, the clocks for the CPU are held high until released by the cache chip on the next cycle. Error correction on multi-byte data is performed using, for example, the 72/64 Hamming code. The technique requires a 2-port cache array (one write port, and one read port). However, the density of a true 2-port array is too low; therefore, the technique is implemented with a 1-port array using a time multiplexing technique, providing an effective 2-port array but with the density of a single port array.

Title: Tobacco smoking article
IPC: A24F42/10
Filed: 1990-04-25
Abstract: A cigarette (9) provides tobacco flavor by heating tobacco (11), but not burning tobacco or any other material. A heat source (35) which includes granular magnesium, granular iron, and finely divided cellulose generates heat upon contact thereof with an aqueous solution of potassium chloride. The heat source is in a heat exchange relationship with the tobacco. Heat generated by the heat source heats tobacco in a controlled manner. Flavors volatilize from the tobacco and are drawn from the cigarette and into the mouth of the smoker. Typical heat sources heat the tobacco to a temperature within about 70<o>C to about 180<o>C for 4 to 8 minutes.

Title: Apparatus for using hazardous waste to form non hazardous aggregate
IPC: F23G5/16
Filed: 1990-12-12
Abstract: Hazardous waste is formed into non-hazardous non-leaching aggregate by introducing the material to a rotary kiln where the large solids are at least partially combusted to form a primary aggregate. Gaseous combustion by-products and waste fines from the waste materials are introduced into at least one oxidizer having water-cooled metal walls. Some of the waste fines are melted to form a molten slag-like material that is removed from the apparatus and cooled to form non-hazardous aggregate. The portion of the material in the oxidizer that is not melted, is cooled, neutralized and subjected to a solid gas separation. The solid is reintroduced to the oxidizer with the primary aggregate where they are either melted or entrained within the molten material and become an integral part of the non-hazardous aggregate. <IMAGE>
