Abstract: 1,134,187. Blending fibres. CARDING SPECIALISTS (CANADA) Ltd. 12 Sept., 1966 [31 Aug., 1965], No. 37177/65. Headings D1F and DIN. A method of mixing and blending textile fibres comprises submitting at least two different feeds of fibres 3,4 to separate carding means 1, 2 to produce separate webs 7, 8 and delivering the separate webs to common carding means 20 to mix and blend the fibres. As shown the separate webs may be fed to separate taker-in rollers 17, 18 but alternatively they may be fed to a single taker-in. Pressure rollers 12, 13 before and 25, 26 after the common carding device may be provided. Between doffers 9 and cylinder 19 and between doffer 22 and calender rollers 27 the rollers may be driven to draft the fibres.

Title: Meta-bis-anilide derivatives and their use as herbicides
IPC: C07D307/68
Filed: 1968-08-06
Abstract: 1,241,702. Meta - bis - anilide derivatives. STAUFFER CHEMICAL CO. 6 Aug., 1968 [11 Aug., 1967; 1 July, 1968], No. 37430/68. Heading C2C. [Also in Division A5] The invention relates to meta-bis-anilide derivatives of the general formula in which R 1  and R 2  are independently hydrogen, alkyl, alkoxyalkyl, cycloalkyl, lower alkenyl, halogenated lower alkyl, benzyl, furyl, ethyl phenyl, styryl, phenyl or substituted-phenyl in which the substituents are nitro, halogen, methyl or methoxy; R 3  and R 4  are independently hydrogen or lower alkyl; X and Y are independently oxygen or sulphur; and Z is halogen, nitro, amino, lower alkyl, lower alkoxy, or trifluoromethyl and n is an integer having a value from 0 to 4; provided that when R 1  and R 2  are both the same alkyl, X and Y are both oxygen and R 3  and R 4  are both hydrogen, then n is an integer having a value from 1 to 4. The compounds may be prepared by the condensation between the appropriate m-phenylene diamine and an appropriate acid anhydride or chloride to prepare the desired meta-bissymmetrically substituted anilide, or by the condensation between the appropriate m-monosubstituted amino anilide and an appropriate acid anhydride or acid chloride to prepare the desired meta - bis - asymmetrically substituted anilide. In an example isobutyric anhydride is reacted with m-phenylene diamine to prepare meta-bis-isobutyryl anilide. In another example M-amino-propionanilide is reacted with cyclopropane carbonyl chloride to produce meta-propionamido cyclopropane carboxanilide. Many compounds are claimed per se.

Title: Method and apparatus for inspecting hollow articles for line-over finish defects
Inventor: MATHIAS BENNY BERT
IPC: G01N21/90
Filed: 1963-09-24
Abstract: 1,019,184. Photo-electric inspection for surface defects. OWENS ILLINOIS INC. Sept. 24, 1963, No. 37438/63. Heading G1A. A method of inspecting for defects on the surface of a hollow article of translucent material e.g. the surface S (Fig. 1) of the rim F of a glass container C, comprises scanning the surface with a beam of light polarised in a direction perpendicular to the plane of incidence, the angle A between the beam and a vertical to the surface being substantially equal to Brewster's angle and intercepting that portion of the beam reflected vertically from the surface in order to obtain a signal from it. Polarised light is used in order that only surface defects are detected, so that defects inside the glass will not cause false rejection of a container. The container C is mounted on a support 10 which is rotated so that the polarised light, from two sources 11, 12, scans the entire surface S. This is carried out by focussing by means of lens 17, the light from the elongated incandescent filament 15, through a polariser, on to the surface S. If light falls on a surface defect e.g. a groove or notch D (Fig. 20, some of it will be reflected vertically upwards into lens 21, through filters 28, 29, to appear as an image of the defect in the aperture 23. As a defect is present, the intensity of the image will be sufficient to energize the photo-cell 24, creating a signal which is amplified by amplifier 25, to energize a relay 26 and actuate a reject mechanism 27 which can eject the container from the support 10. Alternatively, a time delay device may be energized carrying a reject mechanism to be operated after the container has been removed to a conveyer. The polarising filters 28, 29, provided in the housing 20, control the intensity of the reflected light and permit adjustment of the sensitivity of the photocell 24. Two light sources 11, 12 are used to ensure that both symmetrical and asymmetrical defects are detected. The light source and photocell housings are mounted adjustably by an arrangement of clamps.

Abstract: A detergent additive for lubricating oil comprises a mixture of a phosphosulphurized polyolefin together with an alkyl phenol sulphide or an alkylphenol which has been reacted with an oxide or hydroxide of a divalent metal.  The process is carried out at moderately elevated temperature at 40 DEG  to 80 DEG  C. in the presence of an inert solvent until neutralization of the mixture has occurred.  The product is added to a lubricating oil in an amount corresponding to a divalent metal content between 0.05 and 2% by weight of the final composition.  The product can be used alone as a lubricating or additive but is preferably employed together with a sulphonate detergent additive such as the divalent metal salt of a sulphonated aromatic hydrocarbon.  The weight of sulphonate additive is preferably not more than 50% of the combined weight of itself and the product of the invention.ALSO:A detergent additive for lubricating oil comprises a mixture of a phosphosulphurized polyolefin together with an alkylphenol sulphide or an alkyl phenol which has been reacted with an oxide or hydroxide of a divalent metal.  The alkyl phenol sulphide or the alkyl phenol is preferably one which has an aromatic nucleus that is substituted by an alkyl group having 5 to 20 carbon atoms. A sulphide is preferably used and may be a monosulphide, disulphide or polysulphide. The polyolefin that is used in phosphosulphurized form is preferably one of relatively low molecular weight, e.g. a polypropylene or polyisobutylene obtained by conventional methods.  It is preferred to employ the alkylphenol sulphide or alkylphenol and the phosphosulphurized polyolefin in a weight ratio between 1 : 1 and 1 : 4.  The metal oxide or hydroxide is preferably that of an alkaline earth metal or zinc and is used in such quantity as to ensure neutralization of the mixture.

Title: Improvements in or relating to thermionic valve circuit arrangements

Abstract: 375,273. Valve-amplifying circuits. KRAMOLIN, L. L. DE, 35, Landshuterstrasse, Berlin. Dec. 18, 1930, No. 38243. Convention date, Dec. 18, 1929. Void [Published under Sect. 91 of the Acts]. [Class 40 (v).] An automatic gain control system comprises two valves having different operating character. istics so that for weak signals one valve has little effect, whereas for strong signals it opposes the amplifying action of the other valve to give practically constant output. Fig. 1 shows a pair of push-pull valves 2, 3, one of which operates on the straight part of its characteristic while the other has a curved characteristic and operates at a point to the left of the lower bend. A fairly constant output is thus applied to the rectifying valve 5. In Fig. 4 a negatively biased rectifier 8 is con. nected in parallel with the amplifier 7. For weak signals valve 8 is almost inactive, while with large inputs it draws a large anode current, thus increasing the voltage drop across resistance W and thereby decreasing the amplification of valve 7 by reducing the applied anode voltage. A manual volume control may also be provided in the stage following the automatic control stage.

Both sets of gears have different numbers of teeth so that the shaft of the lower output roller, which is geared to the shafts 31, 32 can be driven at a selected one of a number of different speeds according to which clutch is engaged. The variations in the thickness of the sliver are read by the top input roller 1, movements of which displace the elements of a memory-device 3; according to these displacements, a rack 4 is moved to rotate a gear 5 to operate one of a series of switches 7..10 controlling the clutches. The memory-device comprises pins 44, Fig. 4, which for adjustment by the movements of roller 1 can slide in the articulations of chains 42 passing over driven sprockets 40, 41.
