IPC: A43D71/00
Filed: 1923-07-12
Abstract: 222,596. Gimson Shoe Machinery Co., Ltd., and Bagshaw, C. M. July 12, 1923. Loose-nailing.-An apparatus for supplying tacks to a nailing-machine, particularly for securing the pulled-over upper of a boot, is arranged to supply, for simultaneous driving, a plurality of any one or other of a plurality of different lengths of nails. Two rotary tack-pots 8, 9 supply tacks respectively to raceways 20, 21 arranged to be slidable in a longitudinal direction within the tack-pots and communicating with raceways 16, 17 formed with a block 15 pivoted to the frame at a point near to, and midway of the tack-pots 8, 9. At the lower end of the raceways 16, 17 is a separator 18, and the block 15 can be moved to put either raceway in communication with the separator by means of a hand lever operating through an eccentric 35 and stud and strap connection 33. The hand lever also operates a rocking lever 47, through a second eccentric 39 and connections 41, 43, 45, to move the lug 31 of one or other of the clearers for the raceways 20, 21 into the path of cam blocks 32 on the tack-pots. The lever 47 carries set screws 51 which contact with spring-pressed extensions 27 of the lugs 31. The meeting ends of the raceways 20, 21 and 16, 17 are held in close contact bv springs 22, 23. The separator 18, which is carried by a yoke 76 normally held to the right by a spring in a housing 77, is reciprocated to divide off the required number of nails by the engagement of projections 69 on a disc 68 mounted on a rotary shaft 67 with a roll 70 on a block 73 adapted to contact with the shaft 74 which carries the yoke 76. From the separator the tacks pass to a passage 17 and thence to tubes 58 - - 62, which are presented successively to the passage 19 by means operated by a cam disc on the shaft 67 in a manner substantially similar to that described in Specification 175,691. In operation, the block 15 is adjusted in accordance with the length of nail to be used, this adjustment also bringing the appropriate clearer into operation, and each nail tube receives a nail. Three studs or pins are arranged below the raceway 19 at different distances from it to ensure the inversion of the nails whatever their length may be.

Title: Improved method and apparatus for measuring film thickness
IPC: B29C48/92
Filed: 1966-04-27
Abstract: 1,147,946. Photo-electric thickness measurement. INDUSTRIAL NUCLEONICS CORP. April 27, 1966 [April 27, 1965], No.18563/66. Heading G1A. A photo-electric thickness gauge moves back and forth across the width of a moving double sheet of plastics material to detect any unevenness of thickness. The double sheet is formed by blowing a bubble of the material as it is extruded from a circular die rotating the bubble relative to the die and then flattening the bubble between take-up rollers; any unevenness in the amount of material issuing from a particular hole in the die creates a streak of uneven thickness which in the final flattened sheet runs in zig-zag fashion across the top and bottom surfaces of the sheet and which can be detected by the moving gauge. The gauge scans the sheet at the speed at which the streaks appear to move across the moving sheet at the scanning location, streaks on one layer moving in the direction of scanning and on the other layer moving against the scanning direction. The speed of scanning is dependent upon the speed of the sheet and the width of the sheet. The gauge output is recorded upon a chartwhose scale is correlated with particular holes of the circular die. By comparing the output signal of the moving gauge with that of a thickness gauge fixed at one edge of the sheet streaks extending substantially in the direction of movement of the sheet can be detected. Alternatively the scanning gauge may be temporarily stationary at the edge of the sheet; its signals either when scanning or when fixed at the edge being recorded for subsequent comparison.

Title: Process of making dialkylaminoalcohols
IPC: C07C215/08
Filed: 1935-06-29
Abstract: Diethylaminoalcohols are produced by reacting a monoalkylolamine with one or two mols of a dialkyl sulphate whose alkyl radicles each contain less than four carbon atoms. Ethanolamine may be reacted with one mol of diethyl sulphate forming an addition compound which is then treated with aqueous alkali to produce monoethylamino-ethanol and alkali ethyl sulphate, and on adding a second mol of diethyl sulphate and then adding aqueous alkali, the diethylaminoethanol is produced.  Both alkyl groups of the diethyl sulphate may be utilized by using more drastic conditions.  The product is distilled under reduced pressure, water being added during the distillation to keep the alkali salt in solution The free amine in the distillate may be separated from the water by adding an azeotroping agent such as toluene, benzene, or ethylene dichloride and distilling under reduced pressure such as 100 mm. or less, the added liquid being returned to the still from the condensate.  The reaction temperature may be 20--50 DEG  C. or, when both alkyl groups of the dialkyl sulphate are to be utilized, 100--200 DEG  C.  The Specification as open to inspection under Sect. 91 is not limited to dialkyl sulphates in which the alkyl groups contain less than four carbon atoms each.
