Abstract: 1,177,545. Pyrrolidone derivatives. KALLE A.G. 8 Nov., 1967 [10 Nov., 1966], No. 50872/67. Heading C2C. [Also in Division G2] Diazonium salts of formula in which R 1  is an alkoxy group with 1 to 5 carbon atoms, R 2  is hydrogen, chlorine, methyl, ethyl or alkoxy with 1 to 5 carbon atoms, R 3  is hydrogen or methyl and X is anion are prepared by reacting the appropriate 2-alkoxy benzyl. amine with the butyrolactone to produce the corresponding 1 - pyrrolidono - benzene. This compound is nitrated with nitric acid in the 4-position and then reduced to the amine with Raney nickel. The amine is diazotized with acidic sodium nitrate to produce the diazonium salt. The benzylamine may be nitrated before reaction with the butyrolactone.

Abstract: 511,043. Cosmetics. EIMBARA, R. Feb. 9, 1938, No. 4112. Convention date, March 17, 1937. [Class 81 (i)] [Also in Groups IV, III and VIII] Dispersions and emulsions of normally insoluble substances, suitable in some cases for the manufacture of skin creams and other agents for the treatment of living tissues, are made by means of sulphonated or unsulphonated compounds of the general formula R1.COOR2.COO.R3, where R1 is an aliphatic saturated or unsaturated radicle containing at least 10 carbon atoms, and, if desired, hydroxyl groups or other substituents, R2 is a lower aliphatic radicle containing 1-3 carbon atoms, e.g., methylene, ethylene or propylene, and R3 is an aliphatic, cyclo-aliphatic, aromatic or aliphatic-aromatic radicle containing not more than 7 carbon atoms, and, if desired, ester or free hydroxyl groups. The substances emulsified include natural and artificial oils, fats, waxes and resins, and fat-like substances, e.g., fat alcohols and derivatives of fatty acids. In an example a white salve is made by emulsifying petroleum jelly with the acid of the monoglycol ester of stearoyl-glycollic acid (made by reacting sodium stearate with the monoglycol ester of chloracetic acid) and caustic potash solution. The Specification as open to inspection under Sect. 91 describes the similar use of compounds of the general formula set out above, but in which R1 may be any higher saturated or unsaturated radicle, R2 may be methylene or a homologue thereof and R3 may be any aliphatic, cycloaliphatic, aromatic or aliphatic-aromatic radicle. This subject-matter does not appear in the Specification as accepted.

Abstract: 1391537 Security-sealed merchandize bag PAKLINE CORP 7 Nov 1972 [22 Feb 1972] 51232/72 Heading B8C A method of providing a security-sealed merchandize bag comprises the steps of selecting a plastics bag 15 having a single top mouth opening 16, inserting purchased items in said bag, folding a top portion of the bag over on itself about a given fold line 19 so that said top mouth opening is spaced downwardly from said fold line, heat-sealing the folded portions along a first path 20-22 between said fold line and mouth opening, simultaneously with said heat-sealing, perforating the folded portions along a second path 23 between said fold line and said first path to define a tab, and bending the tab out of the plane of the bag to leave an opening defining a carrying handle for the bag. As shown, a cashier at a check-out counter 10 of a store, selects a plastics bag 15, inserts purchased items 17 into the bag through the bag opening 16, and then places a bar 18, preferably of plastics, on top of the bag 15 to define a fold line 19 the top portion of the bag then being folded down about the bar 18 and inserted into the opening 13 of a heat-sealing apparatus 12. The cashier then depresses a handle 14 of the apparatus 12 to provide a heat-seal 20-22 along the first path and simultaneously, by means of a special hot-wire, not shown, a perforated line 23 along the second path just above the rectangular seal-line portion 21. The upwardly-slanting seal-line end portions 26, 27 retain the bar 18 in position, gaps 24, 25 in the seal-line 20-22 avoiding weaknesses in these parts after the tab has been bent out of the plane of the bag to form a handle. The bar 18, which forms a reinforcement for the handle, could be omitted from the bag which is preferably transparent.

Abstract: 1,171,154. Prostoglandin derivatives. UPJOHN CO. 28 Nov., 1966 [29 Dec., 1965], No. 53202/66. Heading C2C. Novel racemic compounds of the formulµ 11B, 13B, 10B, 12B, 10D, 12D, 10C and 10A (wherein R is C 1-8  alkyl, X is H or CH 3  but only one CH 3  group can be present in a given side chain, Y and Y<SP>1</SP> are H or acyl derived from C 1-12  hydrocarbon carboxylic acids, Z is H or C 1-12  hydrocarbyl, W is H, C 1-8  alkyl which may be substituted or C 6-8  aryl which may be substituted, and n is zero, 1 or 2) are prepared by the processes illustrated below and are converted to compounds of the formula 11A, 14C, 14A, 15, 12A, 12C, 13A, 14D and 14B by the processes also illustrated below. 9B#10A and 9B#12A are Wittig reactions. 10A#10B and other similar processes are hydrolyses of 3α,5α-acetals to the free 3α,5α-diols (these may, if required, be reconverted to acetals). 10B#10D and other similar processes are reductions involving conversion of a keto group to an OH group with, e.g. NaBH 4 . 10A#11A and other similar processes are catalytic hydrogenations of an ethylenically unsaturated to a saturated side chain using palladium or rhodium catalysts. These processes may be effected in any order. Simultaneous keto and side chain reduction, e.g. 10A &c.#14A, is also effected by catalytic hydrogenation using Pt, Raney nickel and other catalysts. 14A includes isodihydroprostaglandin F 1α  and like compounds. 15 includes dihydroprostaglandin F 1α  and like compounds, obtained by reduction of 10A, 10B, 10C and 10D under conditions leading to rearrangement of the unsaturated side chain at the point of attachment to the cyclopentane ring, e.g. by hydrogenation at above room temperature in the presence of a hydrogenmobilizing catalyst, with, when required, hydrolysis of the acetal grouping. Hydrolysis of the ester group of compounds 10A-D, 11, 12A-D, 13, 14A, 14B and B is effected by conventional procedures; the thus-obtained free acids may be re-esterified or converted to salts. Similarly, free hydroxy groups may be acylated and acyloxy groups hydrolysed. Wittig reagents of the formula are prepared from triphenylphosphine and an appropriate halo-acid or -ester with subsequent basification of the phosphonium halide first formed. The novel cyclopentane derivatives of the invention, which are used in the treatment of hypertension, may be made up into pharmaceutical compositions with suitable carriers.

In Fig 2, each carrier bar 6 is suspended from pairs of rollers running within an inverted channel formed in the frame section 1, and is laterally displaced by a double-acting pneumatic or hydraulic jack 18, 20. The nozzles 7 are carried by supports 15 adjustably clamped to the carrier bar 6 so that the lateral spacing and height of the nozzles may be adjusted. In a modification of Fig. 2, the 'carrier bars 6 also carry tool holders alternately (or randomly) between the nozzle supports 15, so that the soil between the rows 4 can be worked as the rows 4 are being sprayed. Alternatively, the nozzles and tools can both treat the soil between the rows 4, or the rows 4 themselves. The nozzle supports 15 and tool holders are only adjustable in height.

A stream of fuel vapour 8 together with air 7 or other source of O 2  is passed through the catalyst bed 3, and ignited. Initially the fuel burns with a flame but soon "lights back" into the catalyst bed and burns flamelessly. When flameless burning has been established the chlorinated hydrocarbon is introduced through inlet 7. The maximum temperature in the catalyst bed is preferably 400-500‹ C. The gases leaving the bed are passed through a Dreschel bottle containing water to remove HCl and CO 2  may be vented into the atmosphere.

The speed of scanning and frequency of clock pulses must remain constant for any one scan but may vary from scan to scan. In one arrangement Fig. 1 (not shown) the calibration scale, comprising a plate with two slots illuminated by optical fibres defining the marks, is placed in an intermediate image plane of an optical microscope viewing the object. In another arrangement Fig. 6 (not shown) images of the object and scale are superimposed directly on the vidicon tube. As well as measuring the dimension of an object its degree of offset from the optical axis of the measuring instrument may also be determined by employing three counters.
