Title: Open-end spinning thread guides
Inventor: MAIXNER VACLAV
IPC: D01H4/40
Filed: 1982-10-20
Abstract: The subject matter of the present invention consists namely in that the effect of frictional forces acting upon the yarn at the first contact point in the withdrawing path behind the collecting surface of the spinning rotor is reduced by shortening the contact path of the withdrawn yarn, such that the axial force of the withdrawn yarn in the area behind the outlet of the funnel does not exceed a 2.5 multiple of the axial force   <IMAGE>  where: Fo=the axial force in the withdrawn yarn in the area between the collecting surface of the spinning rotor and the inlet into the withdrawing funnel (mN/tex> R=the radius of the spinning rotor (mm),  n=the number of revolutions of the spinning rotor (min<-1>).   The working surface of the funnel of the yarn exit guide is formed by an inlet edge 4 and the section, defined by said inlet edge and the last point of contact of the yarn on the working surface. The contact path of the yarn at a given radius of curvature r of the exit guide is reduced by truncating the upper surface at a height h. <IMAGE>

Title: Splicing webs automatically
Inventor: GOODING TREVOR FRANK JOHN
IPC: B65H19/18
Filed: 1983-02-15
Abstract: During splicing, the fresh web reels are positioned at which reels loaded from a magazine at a first station (I) and moved to a second station (II) in which a clip holding a leading end of the fresh web is picked up by reciprocating carriage (38) and moved to a splicing assembly (B). The expiring web in the third station III also runs through the splicing assembly (B) to a web consuming machine, eg a cigarette making machine. When a reel at the third station (III) is near exhaustion, its web is spliced to the fresh web extending from the reel at the second station whilst the expiring web is stationary. The reel bobbin at the third station (III) is then indexed back to the first station, where it is ejected from the star wheel support (2). The arrangement enables fresh web reels to be automatically loaded and spliced on the web supplying unit. <IMAGE>

Title: Detecting combustion in i.c. engine pre-combustion chambers
Inventor: HERBERT ASHLEY JOHN
IPC: F02B3/06
Filed: 1983-04-05
Abstract: A conductive probe 18 extends into the pre-combustion chamber transfer passage 13, the probe being mounted in electrically insulated relationship within an aperture 19 extending from the passage to the face of the cylinder head 10 presented to the cylinder block. A gasket 16 is located between the head and the block and incorporates in insulated relationship a conductor 20 which terminates at the probe 18 and its outer end in a terminal 22 for connection in use to an electrical circuit which detects ionization of the gases flowing in the passage and hence the start of combustion of fuel in the combustion space. The signal can be used to control the timing of fuel delivery to the combustion chamber. <IMAGE>
Patent GB-2121106-A (GB)
Title: An ignition distributor for combustion engines
Inventor: ASSENHEIMER JURGEN
IPC: F02P7/10
Filed: 1983-04-05
Abstract: A corrugated spring washer (36) is positioned in an annular groove (15) in a housing (10) and biasses the distributor shaft (20) in one direction by acting on a stop washer (34) thereby forming an axial clearance (37). Movement of the shaft in the opposite direction is limited by the abutment of the stop washer (34) against the end surface (14) of the housing (10). In that case, the maximum compressibility of the corrugated washer (36) is not exceeded so that overloading of or damage to the corrugated washer (36) is prevented even with large axial oscillations of the cam shaft cooperating with the shaft (20). <IMAGE>

Patent GB-2155650-A (GB)
Title: Controlled exposure
Inventor: ECHIZEN HIROSHI
IPC: G03F7/20
Filed: 1985-02-07
Abstract: In a step-and-repeat wafer exposure process using chopped continuous or pulsed laser light (eg excimer laser light), each exposure is effected in two parts, viz a first coarse exposure of comparatively large preset energy and a second fine exposure of comparatively small preset energy, the amount of the second exposure being calculated in dependence on the amount of the first exposure as measured during the first exposure using a semi-transparent mirror (3, Fig. 1), measuring device (7), and control and memory unit (8). The first coarse exposure may comprise one or more pulses. In the second fine exposure, the output setting of the light source may be adjusted; alternatively, an ND filter or a diaphragm may be employed. The invention substantially overcomes the problem of deviation of energy output from a preset value. As shown, a plurality of first part coarse exposures are followed by a plurality of second part fine exposures. <IMAGE>

Title: Combined sensor device for detecting toxic gases
Inventor: STETTER JOSEPH ROBERT
IPC: G01N27/416
Filed: 1985-02-12
Abstract: An instrument capable of detecting low concentrations of a pollutant or other component in air or other gas, includes a combination of a heating filament (10) having a catalytic surface (14) of a noble metal for exposure to the gas and producing a derivative product from the component, and an electrochemical sensor, including sensing, (18), counter (21) and reference (22) electrodes, responsive to the derivative product for providing a signal indicative of the product the gas passing via inlet (26) and outlet (28). At concentrations in the order of about 1-100 ppm of tetrachloroethylene, neither the heating filament nor the electrochemical sensor is individually capable of sensing the pollutant. In the combination, the heating filament converts the benzyl chloride to one or more derivative products which may be detected by the electrochemical sensor. In another arrangement the heated filament may also act as a sensor which emits a signal if the presence of pollutant is at a concentration above 0.5 to 1% which signal operates a valve to cause the derivative formed by the filament to be directed away from the electrochemical sensor. If no signal is produced the derivative passes to the electrochemical sensor. <IMAGE>

Title: Method of measuring pore pressure in impermeable rocks
Inventor: FITZGERALD WILLIAM J
IPC: G01V1/50
Filed: 1985-04-24
Abstract: If velocity of sound VP in an impermeable rock is plotted against the square root of differential pressure PC-PP where PC is confining pressure and PP is pore pressure, a straight line curve results. Pore pressure can thus be calculated from velocity of sound measurements and the known confining pressure. In drilling a bore hole, the mud weight can be adjusted accurately to be just above the pore pressure so as to minimise the risk of blow-out without putting excessive weight on the drill bit. The method of measuring pore pressure may also be applied to establishing a desired pore pressure in a rock sample, by control of the temperature thereof. <IMAGE>
