1. Moulding material filled with starch for rigid polyurethane foams, characterised in that the starch filler component represents 3 to 40% of the total weight and at least 80% of it consists of gelatinized starch, which is substantially free of particles of a diameter exceeding 3 mm and has a maximum water content of 15% by weight.

1462791 Television recording and playback MCA DISCO-VISION Inc 15 Feb 1974 [20 Feb 1973] 7021/74 Heading G5R A video recording made by a modulated laser beam is read by a second laser beam distinguished from the recording beam by having a different wavelength. As shown, a beam 40 from an argon ion laser 30 is modulated by video signals in a Pockels cell 32 and passes via a Glan prism 38 and a micr...

PURPOSE:To provide a foam which has a thin skin and exhibits an elestic cusioning ability under a high load, by extrusion-expanding a mixture of a polyolefin and a polystyrene in the presence of a hydrogenated styrene/butadiene block copolymer having a specified composition. CONSTITUTION:A styrene/butadiene block copolymer having a styrene content of 10-38wt% and a 1,2-bonded butadiene unit conten...

A new polymer composition comprises an aromatic polyetherketone or mixture thereof containing the repeating units -O-Ph-O-Ph-CO-Ph-I and -O-Ph-Ph-O-Ph-CO-Ph-II (where Ph is phenylene) in the relative molar proportions I:II of 95:5 to 60:40 and 5-80% w/w of a fibrous reinforcing agent. It is suitable for producing shaped articles of high damage tolerance by hot fabrication followed by slow cooling.

PURPOSE:To ensure the safety of an air-over hydraulic brake device in which oil from a brake booster operated in accordance with an air signal is fed into a wheel cylinder, by operating the wheel cylinder with the use of a spring brake when a failure of the oil system is detected. CONSTITUTION:Normally, air pressure from an air tank 15 is fed into a brake chamber 7 through a release valve 14 in wh...

Polyurethane foams prepared from the reaction of polyester polyol with organic isocyanate have improved flame retardance and dripping ember retardance by incorporation of an additive comprising (1) halogenated flame retardant, and (2) water or alcohol soluble urea-formaldehyde resin.

To control transmission ratio of a continuously variable transmission connected to a combustion engine (e.g., for optimal fuel efficiency of a powered vehicle), effective diameter of pulleys is controlled in response to an electrical signal. A control signal suitable for comparison with hydrostatic pressure values is produced by a computing device based on input signals representing load, speed, a...
