Patent GB-1049730-A (GB)
Title: Embossing leather
IPC: C14C11/00
Filed: 1964-11-27
Abstract: In embossing and decorating leather, a surface of the leather, e.g. the grain surface, is coated and slightly impregnated with a paraffin or a wax, and a pattern is then impressed on the surface by an embossing device, such as a roller operated mechanically or by hand, heated to a temperature between 200 and 650 DEG C., e.g. between 250 and 650 DEG C. During embossing of the leather, it is preferably backed by an elastic or resilient support.  The paraffin or wax may have a melting point between 50 and 70 DEG C. Specified paraffins are: tetracosane, pentacosane, tricontane and hentricontane.  A suitable wax is beeswax.  The paraffin or wax may be applied to the surface of the leather in the form of an aqueous emulsion containing between 5 and 15%, e.g. 10%, by weight, of the paraffin or wax and, if desired a small amount, e.g. 1.2%, of an emulsifier. Between 2 and 20 grams of a 10% emulsion may be applied per square metre of the surface of the leather.  In order to prevent the paraffin or wax penetrating too deeply and too quickly into the leather, its surface may be pre-treated with an aqueous dispersion containing between 0.5 and 2.0%, e.g. 100%, by weight, of one or more than one of the substances: egg albumen, blood albumen, casein, e.g. acidic milk casein, and a non-thermoplastic albuminoid condensation product. Between 3 and 30 grams of a 1.0% dispersion may be applied per square metre of the surface of the leather. Additional decorative effects may be obtained by embossing leather dyed with a heat-changeable dye.

Abstract: 1,075,969. Welding by pressure. CROMPTON PARKINSON Ltd. Feb. 24, 1966 [Nov. 27, 1964], No. 48345/64. Heading B3R. A stud for stud welding comprises a flanged shank and extending back beyond the flange coaxially with the shank a portion connected to the flange by a narrow neck, so that it can be broken off after welding. In securing a small plate (1) having a hole (3) surrounded by a recess (4), to a metal surface (2), a stud having a conical-ended shank (5) with a flange (8) arid a break-off portion (9) connected to the flange by a narrow neck (10) is arc stud welded through the hole (3) so that the flange (8) fits into the recess (4) against the plate (1). The portion (9) is then broken off. The plate (1) may be of insulating material or may be of metal when stove enamel is provided on the plate (1) or stud where they are adjacent. The plate (1) may have gas venting passages in the form of slots (17), Fig. 3 (not shown), or grooves (18), Fig. 5 (not shown).

Title: Coiler for continuous reeling of wire and like flexible material
IPC: B65H67/048
Filed: 1971-10-20
Abstract: 1367513 Continuous winding VSESOJUZNY NAUCHNO-ISSLEDOVATELSKY I PROEKTNOKONSTRUKTORSKY INSTITUT METALLURGICHESKOGO MASHINOSTROENIA 20 Oct 1971 48690/71 Heading D1J In a continuous winding apparatus of the kind having a turntable 1 on which are mounted two driven bobbins 4, the wire 30 to be wound passes initially along a trough 12 extending between the bobbins 4 and thence to pinch rolls 8 and cutting means 10. On each side of the trough 12 are a number of guide rolls 13 arranged around the bobbins 4 as shown. To start a winding operation the turntable is swung from the setting of Fig. 2 to that of Fig. 3. This causes the guide rolls 13 of a first bobbin to hold the wire 30 clear of that bobbin whilst the guide rolls 13 of the second bobbin move to a non-operative setting. As a result the wire 30 is caught by severing and fastening means 14 on said second bobbin and winding up of the wire 30 on the second bobbin then commences. The severed leading end of the wire proceeds through the cutting means 10 that chops it into lengths and deposits these lengths in a scrap box 11. When the winding of the second bobbin is full the table 1 rotates in the opposite direction to a setting in which the wire 30 is caught and cut by the means 14 on the first bobbin and winding up of the wire on the first bobbin then commences. The catching and cutting means 14 on each bobbin comprises a knife 16, Fig. 4, and block 21. As the bobbin rotates the knife 16 is rocked by a roller 28 engaging an annular cam 29 designed to give the knife its rocking motion. When the wire 30 is positioned between the knife 16 and the block 21, the knife 16 cuts the wire and simultaneously clamps the upstream end of the wire against the block 21. The resulting pressure on the block 21 causes a lever 20 to rock downwardly and so release a pawl 17 from its engagement with the lever 20. A nose 18 on the pawl 17 then moves under a pin 26 of the lever 15 on which the knife 16 is mounted to retain the knife in its clamping position.

The support frame 19 has horizontal and vertical flanges 22, 23 for supporting and locating the batteries 16, and downwardly extending flanges 25 for engaging the sides of the truck body 10 have extensions 27 fitting between blocks 26 on the body. As shown the tailweight 17 is attached by bolts 131 to the support frame 19 but it may only rest thereon. Lifting eyes 34 are provided in the support frame 19 for lifting the frame together with the batteries and tailweight, and a casing for the batteries 17 has sockets whereby the batteries can be lifted alone.

Each carrier 12, Fig. 2 (not shown), comprises banks of code pins 40a, 40b raised into the active upper position by levers 38a, 38b in pairs to form a code, a master pin 50 and a load carrying pin 66 which is unloaded by a wiper plate 68 straddling the pin 66 and movable over the pin 66 by depression of rod 71 against spring 72. Rollers 62 stabilize the carrier adjacent the conditioner 14 and the unloader 16. The conditioner 14, Fig. 3 (not shown), comprises a cam plate 106 engageable by the leading raised code pin on a carrier to cause the whole assembly 14 to move outwardly on hinges against a return spring whereupon the master pin 50 is raised by engagement with a cam plate 140. If two code slots 102, 104 in plate 100 of the conditioner match the spacing of the coded pins when the master pin is aligned with a slot 124 in a further plate 122, the three pins pass therethrough allowing the conditioner to return to its original position in which a cam 120 thereon returns the code pins to their inactive position. If the code pins do not coincide with the code slots of the conditioner, the carrier passes through the conditioner without the code pins being depressed but the master pin is depressed by cam 126. The unloader means 16 comprises a cam plate which is engaged by the master pin 50 of a carrier which has been conditioned for unloading, and moves the means 16 outwardly on hinges against a return spring whereupon a flange 196 thereon is brought into engagement with a roller 74 on the arm 72 of the wiper plate 68 causing unloading of the carrier.
