Patent GB-2091305-A (GB)
Title: Insulating materials and methods of making same
IPC: D21J1/20
Filed: 1981-07-03
Abstract: An insulating material which recycles waste paper is produced by pulping the paper and adding to the thus formed pulp a composition including a liquid detergent, sodium carbonate as a fire retardent, and a foaming agent. The material is then allowed to drain whereupon it assumes a pasty consistency which can be used to form moulded blocks or can be applied directly to a surface to be insulated. Alternatively, a part- finished product can be produced by pulping paper, wood pulp or rag, adding to it a liquid detergent, and subsequently allowing the surplus moisture to drain or otherwise be expressed. A fire retardent, which again may be sodium carbonate, a foaming agent, and perhaps also a water soluble adhesive and/or a pigment is then added to the paste and the whole thoroughly mixed or kneaded and either packaged in the moist state or dehydrated and granulated or pulverised. Upon reconstitution by the addition of water the foaming agent expands to form a cellular structure and the amount of water employed for reconstitution can control the consistency of the material in dependence on its intended manner of application.

Title: Control valve for vehicle brakes
Inventor: WILSON ALEXANDER JOHN
IPC: B60T8/24
Filed: 1982-10-12
Abstract: A dual circuit brake control valve has inlets (2,3) connected to respective outlets (4,5) via respective metering valves (6,8). Each metering valve comprises telescopically arranged outer (12), intermediate (14) and inner (13) pistons have respective effective cross-sectional areas of A1, A2 and A3. The clearance space between the confronting ends of the inner pistons (13) is determined by a deceleration responsive member, e.g. a weight (38) rotatably mounted above its centre of gravity and having a helical surface complementary to a helical surface (27) on one inner piston (13). The net effective area of the metering valves (6, 8), which determines the cut-in pressure and input-versus-output characteristics, is A1-A3 or A1-A2 depending on the clearance space (determined by rotation of weight (38)) between the inner pistons at the moment when the pressure subsisting the brake system is sufficient to move the inner (13) and intermediate (14) pistons. Other embodiments show different deceleration responsive members, viz. a ball-and-ramp mechanism (figs 4, 5 not shown), or a pendulum (figs 6, 7 not shown). <IMAGE>

Title: Automatic emptying of spinning cop containers
Inventor: KRENMAYR WILLI
IPC: B65H67/06
Filed: 1982-11-30
Abstract: Spinning cops arranged in an irregular manner in a spinning cop container 5, when the latter assumes its emptying position and a side wall 9 is removed, slide into an antechamber 10 and are positioned on a vibrating feed plate or conveyor belt 13. Due to the directional and feeding action of said feed plate, the formation of build-up bridges, which can occur in the spinning cop container and antechamber is substantially avoided. A plate 12 is provided on the feeding side of the antechamber so that the lower cops are fed before the upper. As a result, the spinning cops can be removed by further means as a continuous flow at the end of the feed plate. Despite the limited space requirements, during the emptying of the spinning cop container, the spinning cops are transformed from their irregular arrangement into a straightened, single- layer arrangement. <IMAGE>

Title: Improved hermetic sealing process
Inventor: WOLFSON SUMNER HAROLD
IPC: H01L21/00
Filed: 1983-05-18
Abstract: A method of effecting a hermetic seal between an electronic component package 12 and a package cover 14 includes the steps of bonding a heater layer 20 of conductive material to a sealing area of the package 12. A sealing material 24 is then applied over a sealing area of the package cover 12. Optionally, a layer of sealing material may be applied over the conductive heater layer 20. The package 12 and cover 14 are contacted together and an electric current induced to flow within the conductive heater layer 20. The sealing material 24 reacts to the heat caused by the electric current flowing in the heater layer 20, and bonds to the heater layer 20 to effect a hermetic seal. Additionally, the seal can be intentionally broken by a reheating process to allow for repair or replacement of the electronic components contained within the package, and then resealed. <IMAGE>

Title: Process for preparing semi- synthetic enzymes
Inventor: KEYES MELVIN HUBERT
IPC: C07K1/107
Filed: 1983-05-27
Abstract: Disclosed is a process for chemically modifying a native protein to produce a biologically active modified enzyme-like protein. A solid support immobilized inhibitor of a model enzyme is prepared. A native protein is partially denatured and brought into contact with the support immobilized model enzyme inhibitor. A cross-linking agent is then added to the protein in the presence of the support immobilized model enzyme inhibitor and the mixture is incubated for a time and temperature sufficient to cross-link the native protein. The modified enzyme-like protein is removed from the cross- linking agent and the immobilized inhibitor and purified to produce a modified enzyme-like protein having the biological activity characteristics of the model enzymatic protein. The thusly prepared modified enzyme-like protein exhibits different biological activity than the starting native protein.
