Title: Improvements in and relating to razor-holders for strip-like blades
IPC: B26B21/26
Filed: 1934-10-04
Abstract: 427,283. Safety razors. ERN, R., 591, Vlierboomstraat, The Hague, and NIEPENBERG, K. F., 19, Kotterstrasse, Solingen, Germany. Oct. 4, 1934, No. 28488. Addition to 426,604. [Class 30] The internal or body member 14 of the razor described in the parent Specification is formed with a groove a adapted to receive, in sliding into the casing, a similarly shaped rim on the latter, and thus to form a dovetailed waterproof joint, which will prevent the passage of foam from the space under the bridgepiece into the interior of the razor. The rim joins the lugs which contact with the area 35 formed on the member 14. The groove may contain packing material such as rubber, which may also be provided on the inner side of the bridge.

IPC: F01D25/26
Filed: 1925-11-12
Abstract: 244,726. Akt.-Ges. der Maschinenfabriken Escher, Wyss, et Cie. Dec. 17, 1924, [Convention date]. Casings; leakage-preventing devices.-Between the nozzle diaphragms 1 and the turbine casing 5 there is provided a thin yielding intermediate casing 10 which is undivided circumferentially and prevents damage to the casing 5 by the expansion of the diaphragms. The casing 10 has hollowed-out. ribs 11, some of which are supported on the casing 5. The first set of nozzles are formed in an extension of the casing 5, and yielding packing rings 14, 15 are disposed as shown. The rings 14 are subjected on one side to the high-pressure steam or gas from the supply chamber 6, and on the other side are connected to exhaust ports 16, 17, so that they are pressed firmly in position. A screw-on cover 8 together with the conical casing 10 presses together the diaphragms. Either the casing 5 or the casing 10, or both, may be conical. Alternatively, they may be of stepped formation. The casing 10 may comprise a number of separate one-piece rings having inter-engaging seatings. All or none of the ribs 11 may be supported by the casing 5, which may be formed of cast iron. The wall of the casing 10 may be corrugated; it may be made thinner towards the exhaust end. In all modifications, the diaphragms, with or without spacing rings, form a closed body at their outer surface.

Patent GB-466650-A (GB)
Title: Process for the manufacture of alkyl derivatives of aminated aromatic hydrocarbons
Filed: 1936-10-22
Abstract: C-Alkyl derivatives of acylated aromatic amines are obtained by treating acylated aromatic amines with alkyl halides or aliphatic alcohols in the presence of a Friedel-Crafts catalyst.  Examples are given in which (1) acetanilide and tertiary butyl chloride yield p-tert-butylacetanilide; (2) acetanilide and tertiary butyl alcohol yield the same product; (3) acetanilide and secondary butyl chloride yield a sec.-butylacetanilide; (4) acetyl-o-toluidine and tertiary butyl chloride yield isomeric tert.-butyl-o-methylacetanilides; (5) acetanilide and isopropyl chloride yield a triisopropylacetanilide; (6) acetanilide and isoamyl chloride yield p-tert.-butylacetanilide (sic); in each example, the reaction is effected in ethylene dichloride in the presence of aluminium chloride; other diluents which may be used are nitrobenzene, methylene dichloride, trichlorethylene, chloroform, and carbon bisulphide.  The products may be deacylated in known manner to yield C-alkyl aromatic amines; thus, p-tert.-butylaniline is obtainable from the product of example 1. Alternatively, the products may be nitrated and then deacylated; thus, the product of example 1 may be nitrated to yield o-nitro-p-tert.-butylacetanilide, which may then be deacylated to yield o-nitro-p-tert.-butylaniline; the latter is useful as an intermediate for azo dyes.

IPC: C09K23/00
Filed: 1932-10-17
Abstract: The wetting, penetrating, and dispersing properties of liquids or plastic preparations used for the treatment of textiles, leather, or other fibrous materials are improved by the addition of esters of tetrahydrofurfuralcohol with aliphatic carboxylic acids containing not more than five carbon atoms.  The esters may be used together with soaps, sulphonated oils, sulphonated higher alcohols or aromatic sulphonic acids in the production of solvent soaps.  In examples: (1) a cleansing bath for textiles comprises Marseilles soap and the acetic or propionic ester of tetrahydrofurfuralcohol; (2) a wetting bath comprises an aqueous solution of the same esters; (3) a bath for cleansing textiles soiled with mineral oil contains the said esters and curd soap; (4) a bath for washing raw wool contains the said esters, and the sodium salt of sulphonated lauryl alcohol; (5) a mixture for removing fat from tanned sheep skins comprises the said esters and trichlorethylene.  The esters may be prepared as follows: (1) tetrafurfuralcohol is esterified with formic or n-valeric acid, using sulphuric acid as esterification agent, which is subsequently removed with barium or lead carbonate; (2) tetrahydrofurfuralcohol is esterified with acetic anhydride.ALSO:The cleansing and dispersing properties of liquids or plastic preparations used for the treatment of textiles, leather, or other fibrous materials are improved by the addition of esters of tetrahydrofurfuralcohol with formic, acetic, n-valeric, propionic or other aliphatic carboxylic acids containing not more than five carbon atoms.

IPC: G01B5/20
Filed: 1956-09-26
Abstract: 810,991. Testing gear teeth. ILLINOIS TOOL WORKS. Sept. 26, 1956, No. 29455/56. Class 106 (2). Apparatus for testing a toothed workpiece 36 in which the workpiece is mounted for indexing movement has a pair of relatively movable contact members 38, 40, having portions for engaging the workpiece 36, the pair of members 38, 40 being movable in unison around endless paths 94, 96 (Fig. 6) into and out of contact with the workpiece which is mounted on a carriage (not shown) adjustable along the track 22. The contact members or fingers 38, 40 are mounted on a block 44, finger 38 being adjustable along a slot 48 by means of a screw 54, and finger 40 being pivoted about a pin 58. The block 44 is slidably mounted by means of roller bearings 104 on one end of a crank arm 78, which is pivotally mounted by a shaft 80 to a longitudinally moving slide 82. The other end of the crank arm 78 is connected to a pin 90 eccentrically mounted on a disc 92 which is revolved by means of a motor 130 acting through shafts 138, 142, 148, connected by universal joints 144 and 150 and gears 162, 164, which give a 2-1 increase in speed. By this means the fingers 38, 40 travel around the endless paths 94, 96. Fig. 6 shows the fingers in their measuring position on the pitch circle of the gear-wheel 36. From this position the fingers move clockwise around their respective paths and in so doing, index the gearwheel one tooth. A dial indicator 62 is mounted on the block 44 in such a way that relative movement between the fingers is indicated on the dial, and the fingers are urged towards the workpiece by a tension spring (not shown). To avoid damage to the indexing finger 38, a third finger 112 (Fig. 3) may be fitted to block 44, and this will engage the workpiece for indexing movement, while the fingers 38, 40 are merely held against it for measuring purposes. Provision is made for manual operation by means of a worm 170 engaging a gear 172, when shaft 166 is retracted from the position shown in Fig. 4 until a spring-biased plunger 178 drops into a groove 182 on the shaft 166. The machine can be set for different sizes of workpiece by adjusting screw 188 to alter the location of the pin 90, adjusting screw 54 to alter the spacing of the fingers 38, 40, and moving the carriage along track 22. The plunger 66 of the dial indicator also operates a standard electrical pick-up head 76 and this actuates the pen of a recording mechanism, to give a permanent record of the irregularities of the gear teeth.
