Title: Process for the production of cycloheptane derivatives
IPC: C07C31/13
Filed: 1964-05-01
Abstract: A process of producing a mixture of cycloheptane derivatives containing principally monohydroxymethyl cycloheptane comprises the catalytic hydroformylation of cycloheptatriene using a mixture of carbon monoxide and hydrogen in which the molar ratio of carbon monoxide to hydrogen is less than 1 : 1. Advantageously, the products are after hydrogenated to convert any aldehyde formed to alcohol and to decompose the cobalt carbonyl formed.  Examples are furnished of processes in which monohydroxymethylheptane and residues containing dihydroxymethylcycloheptane are obtained.  The process may be carried out continuously.  Specifications 861,979 and 1,003,577 are referred to.

Patent GB-635923-A (GB)
Title: Improvements in or relating to lustrous finishes for textiles
IPC: D06Q1/08
Filed: 1947-07-10
Abstract: Textile fabrics are impregnated with an aqueous solution of a thermo-setting resin-forming material containing a non-waxy sulphonated oil in amount sufficient to prevent sticking to glazing rolls, said oil having more than 8 carbon atoms in the chain, drying, passing through a heated glazing calender and washing to remove the oil and unreacted material.  The finish obtained is durable and lustrous and the fabric has a softer hand and a higher tear strength than if subjected to the same treatment in the absence of the oil. Sulphonated castor oil is preferred, and it is used in amount from 2 to 60 per cent of the concentration of the resin-forming materials. Suitably a methylol-urea is used in concentration in the bath from 10 to 30 per cent.  After impregnation the fabric is dried without curing the resin, and glazed at a temperature sufficiently high to cause polymerization of the resin-forming material.  Acid salts such as ammonium phosphate to catalyze the polymerization, and softening agents such as ethyl cellulose may also be present in the bath. In an example, a bath is prepared containing water-miscible urea-formaldehyde precondensate 12.5 lbs., sulphonated castor oil 7.5 lbs., ammonium phosphate 1.25 lbs., ethyl cellulose 1.5 lbs. and water to 100 lbs.  Cotton fabric is impregnated with this solution, air-dried below 200 DEG  F., passed through a friction glazer at 320 DEG  F. and washed in a conventional manner with mild soap, followed by a water rinse.

[Class 89 (i)] [Also in Groups XXII and XXIII] A lock nut stamped from sheet metal has a base flange 16 with lateral segments 14 connected by ribs 11. After tapping the segments are closed in without altering the curvature of the tapped portion, the amount of closing being a maximum at 35 and tapering down to nothing at a point that may be variously selected between this end and the flange. The rigidity of the flange prevents any closing in at this end and ensures the bolt having a free start in the nut.

Filed: 1935-07-03
Abstract: 447,860. Squirting, marking, and measuring rods, tubes, and cables. MACKIE, J. N., 11, Belleview Terrace, Edinburgh. July 3, 1935, No. 19026. [Classes 83 (ii) and 83 (iv)] [See also Group VIII] Materials produced in continuous lengths, such as metal rods, pipes, or cable sheaths passing from an extrusion press to a coiling device, are marked or embossed by apparatus comprising marking and co-operating abutment devices supported on a carrier mounted so that it can rotate on a fixed support, and means for positioning the marking device in relation to a rib or other marking receiving region. A tube 1, Fig. 1, is marked by a type wheel 7 mounted in an adjustable holder 17, an abutment wheel 8 being urged against the tube by a spring 15. The carrier 5 is rotatable on a bearing 12 so that the wheel 7 may be always aligned with a rib 2, and the wheel is located by wheels 9 on each side of the rib. The marking device may comprise a stamp 64, Fig. 13, which is normally held away from the tube by a cam 65 and arm 74, but is permitted by the portion 76 of the cam to be driven against the work by a spring 72. The stamp 64 travels with the tube against the action of a spring 77 until retracted again by the cam. Alternatively the stamp may be actuated by an electric motor controlled by contacts associated with a guide roller. In a further modification, type blocks 58, Fig. 12, are mounted on a chain 59, a sprocket wheel 60 applying the embossing pressure. Some or all of the type in the wheel 7, Fig. 1, may be replaceable. Types 53, Fig. 11, have pins 54 engaging in slots in side discs 56, and have spherical rear faces engaged by the central disc 57 ensuring alignment with the surface to be embossed. In further modifications, the abutment and guiding devices comprise a restricted throat of substantially the same diameter as the work, and carrying a marking wheel in a slot, or a series of rollers may be spaced about the circumference of the work. A measuring device which may be associated with any of the marking devices comprises a gear train 21 ... 27, Fig. 3, the gear 27 meshing with a gear which drives an indicator disc 32. An adjustable contact 37 operates an electrically controlled audible or visible signal. The final gear and disc 32 may be pulled by a handle 35 against a spring out of mesh with the gear 27, the disc 32 then swinging to the zero position under the action of a weight 33.
