Abstract: ABSTRACT To measure the alcohol concentration in exhaled air, the alcohol concentration S of the exhaled air and also the flow rate v of the exhaled air are continually ascertained, and the alcohol concentration S is indicated when G, wherein   , is below a prescribed first threshold value W and when the flow rate v, after it has exceeded a prescribed second threshold value vmin  and until G has fall-en below the first threshold value, has continually been greater than vmin. The apparatus for carrying out this method has a measuring apparatus and a flowmeter disposed in the flow of exhaled air reversal of flow being prevent-ed by a non-return valve, and also in indicating unit.  An AND-gate triggers a linear gate with equal triggering by a first threshold value comparator and a second threshold value comparator and a first flip-flop.  The linear gate serves to transmit the measured value of the measuring apparatus to the indi-cating unit.

Abstract: 21.4.80                                              PP 1244 ABSTRACT        "ELECTRON DISCHARGE TUBE COOLING SYSTEM"      An electron discharge tube evaporation cooling system in which part of a tube to be cooled is immerssed in coolant in a boiler (15), the cooling system further comprising a condenser (18) for vapour generated in the boiler (15), and a coolant reservoir (11). The flow of vapour from the boiler (15) to the condenser (18) experiences resistance in  the interconnecting pipe (17), producing in the boiler (15) a back pressure dependent on the dimensions of the pipe (17).  In order that a desired level (40) of coolant in the boiler (15) can be obtained for a range of back pressures, the coolant is supplied to the boiler via an overflow system (16) having an adjustable overflow level.  The overflow system (16) comprises a chamber (31) open to atmosphere at the top (34) and having at the bottom (33) an opening (36) through which an overflow tube (35) passes. The opening (36) is provided with a liquid tight gland (37) comprising a compressible ring (42) and a pressure member (43) adjustable to allow the tube (35) to be slid through or to lock it in position. .

Abstract: ABSTRACT   A hydrocarbon or heterosubstituted-lactone carboxylic acid or an ester or amide thereof is obtained by reacting a molar proportion of a mono-unsaturated hydrocarbyl-substituted C4-C10 dicarboxylic acid or an ester or anhydride with one molar proportion of a peracid, an alkyl hydroperoxide or hydrogen peroxide oxidiz-ing agent or a thiylating agent at -20°C to 100°C.  If an anhydride or a diester is used as reactant, then the oxidation or thiylation is followed by treatment with water, an alcohol or an amine to lactonise the product.  If an amide is to be produced, a lactone acid is first formed and then reacted with an amine.  Thelactones are useful in the production of oxazoline derivatives which have sludgedispersant properties in lubricating oil.

Abstract: Abstract A liquid jet cannon having a reciprocably movable piston device (6). The piston device is held in cocked position against the action of a gas pressure accumulator (19) by liquid pressure in a first chamber (15) until initiation of a power stroke. The power stroke is initiated by depressurization of a control chamber (16), whereby a valve (11) is moved to its open position so that a flow communication (39) is created between the first chamber (15) and a second chamber (17). The first chamber is thus rapidly depressurized so that the pressure in the gas pressure accumulator (19) drives the piston device (6) into a liquid chamber (14) to produce a liquid jet pulse for breakage of the hard material.

Abstract: Abstract of the Disclosure An improved method for reducing the halogen content of a particulate polyolefin formed by catalytic polymerization of an olefin in the presence of a Ziegler-Natta catalyst is taught which comprises the steps of causing the polyolefin in the dry state to flow into a gas phase fluidized bed, contacting the polyolefin in the fluidized bed with a gas comprising 0.05% to 0.2% alkylene oxide, 5% to 30% water, and the balance inert gas such that the alkylene oxide reacts with halogens present in the polyolefin to form an alkylene halohydrin, removing the alkylene halohydrin from the fluidized bed and thus reducing the halogen content of the polyolefin.  The improvement comprises regenerating the alkylene oxide by contacting the inert gas containing alky-lene halohydrin with a caustic solution in alcohol or water and recovering therefrom alkylene oxide formed by the reaction of the alkylene halohydrin and the caustic solution.

The machine has a control for selectively moving the workhead such that a drill carried thereby undergoes a first cyclic path of engagement with the grinding wheel for grinding a first drill point form and a second cyclic path of contact with the grinding wheel when a second drill point form is to be ground.  The control is further selectively operable for causing the workhead to move a drill successively through said first and second cyclic paths for grinding a third drill point form.  The machine control also is adapted to automatically move the workhead in the foregoing manner, as well as automatically advancing the grinding wheel to a position in close proximity to the drill prior to the grinding operation and then automatically feeding the grinding wheel a further predetermined amount during grinding.

Abstract: METHOD AND APPARATUS FOR DISTRIBUTING CONTROL SIGNALS           Abstract A method and apparatus are described in which the control signals for a data channel are transmitted along with the channel address. The control signal and its address are transmitted on a bit interleaved basis in response to CONTROL select signals that are generated as part of the frame.  In accordance with the invention, the CONTROL select signals are distributed relatively uniformly throughout the frame.  At the receiver, the bits of the control signal and its address are reassembled and the address is used to route the control signal to its proper channel.  Further, the bandwidth assigned to control signaling is increased by inserting CONTROL select signals in all time slots that are available in the frame after the necessary channel select signals and other overhead select signals have been assigned.  This technique is particularly advantageous in a system having a fixed aggregate transmission bandwidth, variable loads and the capability of automatically reconfiguring the frame.
