Title: Cleansing and softening agent
IPC: C11D1/26
Filed: 1931-09-21
Abstract: Sulphuric esters of long chain unsaturated alcohols, such as are obtained by reduction of unsaturated fatty oils, or free acids, esters or amides derived therefrom, are prepared by treatment of the said alcohols with a compound of a tertiary amine and sulphur trioxide in equimolecular proportions.  The latter compounds may be prepared by direct addition or by using a pyrosulphate (cf. Specification 317,736, [Class 2 (iii), Dyes &c.]).  Diluents, other than tertiary amines may be employed.  In examples: (1) a carbon disulphide solution of olein alcohol is added to a mixture of carbon disulphide, dimethylaniline and chlorsulphonic acid; (2) commercial oleyl alcohol or the alcohols obtained from sperm oil are treated with pyridine-sulphurtrioxide; (3) sodium pyrosulphate is added to a heated mixture of pyridine and oleyl alcohol; (4) sperm oil alcohols are treated with a mixture of pyridine and sodium pyrosulphate.  The products are stated to be cleansing and softening agents and their cleansing action upon textiles is increased by the addition of inorganic salts, e.g. sodium chloride or sulphate.  Other wetting agents, detergents, bleaching agents or solvents may be added when treating textiles.  Secondary amines such as alkyl-o-toluidines which react like tertiary amines may be used in place of the latter. Specification 308,824, [Class 2 (iii), Dyes &c.], also is referred to.ALSO:Sulphuric esters of long chain unsaturated alcohols, which may be used as cleansing-agents, are prepared by treatment of the said alcohols with a compound of a tertiary amine and sulphur trioxide in equimolecular proportions.

Abstract: 1463445 Coating shoe assemblies INTERNATIONAL SHOE MACHINE CORP 24 June 1975 [23 Aug 1974] 26786/75 Heading B2L  A cement applying mechanism particularly for a cement lasting mechanism of the kind described in Specification 1454939 comprises a cement extruding nozzle 70 Fig. I or as shown a pair of nozzles, mounted for movement in a rearward direction in a cement applying stroke between an initial location at a boundary between an unwiped position of the shoe assembly 162 and the previous wiped toe position and a final location and mounted for pivotal movement about an upright axis a cement flow directing means viz a portion 250 Fig. 7 of the nozzle passage 88 in the nozzle which extends radially from the axis, and means of a motor 74 to move the nozzle through its cement applying stroke. The nozzle is so constrained that the cement flow directing means 250 is directed laterally of the rearward direction and outwardly from the axis during movement of the nozzle 70 in its cement applying stroke from the initial location to an intermediate location wherein the heel portion of the shoe commences to curve rearwardly and inwardly. This is determined by engagement of a cam 160 with a valve 146.  When the nozzle has reached the intermediate location the nozzle 70 is swung rearwardly and inwardly about the axis by the motor 74 into a position such that the cement flow directing means 250 is directed generally rearwardly from the axis when the nozzle has arrived at its final location. Cement can thus be applied along the entire periphery of the workpiece including its rearmost extremity during the entire cement applying stroke. Cessation of outward movement of the nozzle 70 by the motor 100 caused by engagement of a cam 156 Fig. 9 with a valve 142 and inward movement of the nozzle to the extent permitted by stop bolt 102 Fig. 3, when nozzle 70 is between its intermediate and final locations, ensures that the cement flow directing means 250 is pointing to. the heel end extremity. The nozzles are raised from this position by motors 108, Fig. 3. A wiping operation by wipers 248 Fig. 1 is simultaneously accompanied by rearward movement of a plate 24, Fig. 1 and the nozzles 70 until they reach their idle positions, at which point the cycle is complete and the shoe assembly 162 Fig. 11 can be removed.  The mechanism can be applied to apparatus where cement is applied to different workpieces.

Abstract: 895,815. Linear-dimension gauges. SCHAFER, G., SCHAFER, O., SCHAFER, jun., G., and SCHAFER, jun., O., [trading as KUGELFISCHER G. SCHAFER & CO.]. Aug. 4, 1960 [Aug. 19, 1959], No. 27006/60. Class 106 (2). A device for sorting workpieces according to size consists of a piston 3 disposed in a cylinder 2 and loaded by a spring 6 and so arranged that when the piston 3 is moved by a feeler pin 10 from its rest position it uncovers an entry port 50 for compressed air which then displaces the piston further against the action of the spring to produce a signal operating an automatic sorting device (not shown). The compressed air is supplied through a passage 12 to an annular space surrounding the reduced upper end 11 of the feeler pin 10. The end face 7 of the piston 3 seals this space. If the pin 10 is displaced slightly inwardly the air can act on the whole face of the piston 3 so overcoming the force of the spring 6. This causes the piston to rise to the top of the cylinder and the contacts 13, 14 to make, thus closing the circuit containing the sorting device. In a second embodiment, Fig. 2 (not shown), the piston is in the form of a ball and when it rises it uncovers an escape port leading to a pneumatically-operated sorting device. In a third embodiment two such devices are placed side-by-side and their pistons are moved by pegs operated in sequence by a single feeler.
