Title: Improvements in pneumatic fastener inserting devices
Inventor: VOLKMANN DIETER
IPC: B25C1/04
Filed: 1962-02-16
Abstract: 980,031. Stapling-machines. D. HAUBOLD. Feb. 16, 1962, No. 6119/62. Heading B4C. A pneumatic stapler comprises a differential piston 27 in a cylinder 26 the top of which is supplied with compressed air through a duct 25, the bottom of the cylinder being supplied with compressed air through a valve 36 and a duct 35, operation of the valve to connect the duct 35 to an exhaust duct 39 causing the piston to move down in a working stroke. Release of the valveoperating lever 37 permits compressed air in a chamber 23 to restore the valve to a position in which the duct 39 is closed and duct 35 connected to the chamber 23. This raises the piston, since the lower piston-surface is of larger area than the upper surface, to which compressed air is supplied through ports 25. A driver 42 on the end of the piston-rod drives staples from a magazine 43. The piston 27 has a tubular projection 28 guided within a sleeve 31 the end of which, in the raised position of the piston, engages a seal 34 in an annular recess 33 in the piston. The top area of the piston exposed to compressed air increases by the crosssectional area of the sleeve 31 as the seal 34 moves away from the sleeve. A further seal 32 acts between the projection 28 and the sleeve 31.

Title: Improvements in tools for turning crank-shafts
IPC: B23D37/00
Filed: 1935-02-26
Abstract: 438,242. Lathes. FLOETER, F. S., 516, South Weadock Avenue, Saginaw, Michigan, U.S.A. Feb. 26, 1935, No. 6143. [Class 83 (iii)] A tool for turning bearings and crank pins of engine crankshafts comprises a broach-like member 1 fed in the same direction as the movement of the work W at the point of operation and provided with cutting teeth 2 on the front face for turning the bearings and also with teeth 3 on the side walls for facing the cheeks. The teeth 2 and 3 are both of gradually increasing height, the total rise of the front teeth being shown at X, Fig. 4. The front teeth are preferably arranged in herring- bone fashion, Fig. 3, and (the series) may terminate in a number of closely pitched finishing teeth 2d of constant height. The two parts of the herring-bone are separated by a plain land 2<b> which engages a recess W previously formed on the work and prevents the teeth from cutting too deeply. The face of land is in the plane Z, Fig. 4, which is parallel to the direction of feed of the tool. Preferably, the work makes one and a quarter revolutions while the tool is fed through the pitch distance 4. The cutting edges 3<a> of the side cutting teeth are arranged at about 15‹ to planes perpendicular to the tool axis. Each of the teeth 3 shaves off a spiral zone A, Fig. 7, on the crank cheek, further cuts on the same zone being taken by each succeeding tooth until the tool has been moved completely past the work. The cuttings from this operation pass freely along the passages A<1> between the teeth. In one example, a crank-shaft bearing of 3 inches diameter is rotated at 40 r.p.m. and is tooled by a broach having a cutting part 30 inches long with teeth at ¢ inch pitch each offset by À002 inch from the preceding tooth. The finishing zone is 3 inches long and the rate of longitudinal feed 16 inches per minute. The tool is mounted in a head 7 fed by a screw 9 which is driven from a motor 16 through gearing 13 and reducing gear 15. The work is supported by steady rolls 19, 20 mounted on a member 21 pivoted at 22 and actuated by a toggle handle 24.

Patent GB-713941-A (GB)
Title: Manufacture of tanning agents
IPC: C25B3/23
Filed: 1950-03-07
Abstract: Tanning agents are manufactured by sulphonating a mixture of colophony and a naphthol, reacting the sulphonation product with a phenol alcohol, if desired in the presence of a free mononuclear phenol, and reacting the resulting product with formaldehyde or a substance yielding it (e.g. hexamethylenetetramine).  There are preferably used 1.3-6 (e.g. 2) parts of the naphthol to 1 part of colophony, an amount of phenol alcohol and free mononuclear phenol totalling 1 part to 1 part of naphthol, and an amount of formaldehyde, including that used in making the phenol alcohol, equal to 0.75-0.95 mol. per mol. of total phenol, including that used in making the phenol alcohol.  The sulphonation step may be effected in the same way as the corresponding step in the process of Specification 713,061.  For the next step there is advantageously used a mixture of phenol alcohol and free phenol obtained by reacting one or more phenols with less than an equimolecular proportion (e.g. 0.4 mol per mol of phenol) of formaldehyde (preferably in the presence of a small quantity of an acid or alkaline condensing agent) or of a substance yielding formaldehyde or another compound capable of introducing -CH2OH groups into aromatic nuclei (e.g. methylene chloride in the presence of caustic soda).  In examples: (1) a 1 : 5.6 mixture of colophony and b -naphthol is heated with 100 per cent. sulphuric acid, the sulphonation product is condensed with the reaction product of a mixture of phenol and cresols with less than an equimolecular proportion of formaldehyde, and the condensation product is further condensed with formaldehyde in aqueous solution and then neutralized with ammonia and acidified with acetic acid; (2) mixed cresols alone are used in place of the mixture of phenol and cresols in (1).
