Abstract: 177,755. Boddenberg, C. A. March 26, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Stropping-apparatus.-A device for sharpening or stropping two-edge safety-razor blades has a blade-holder resiliently held between two mutilated stropping-rollers, so that, during each revolution, the rollers are moved from contact with the blade, which is therfore free to turn to present the opposite sides to the stropping-surfaces. Semicircular rollers or carriers a, a<1> having interchangeable spiral stropping-members b, b' are geared. together by wheels f, f<1> and are rotated by a crank j. The blade-holder d, mounted in fluted discs guided in slots e', is pulled towards the stropping-surfaces by springs e<2>, and has its axle bearing against a friction disc h under the action of a spring i.

An indirect addressing scheme in a computer uses a stored table of addresses associated with stored indications of field lengths in different memory blocks. A first instruction accesses a data memory to obtain the number of a connection device (electromagnetic relays) in a telephone network, the number being then placed in a register specified by two bits of a second instruction. Eight further bits of the second instruction are added to 0000000100000000, the result being used to address the data memory to obtain a word in a table therein. Twelve bits of this word, with 0000 following them, constitute the base address of a data memory block containing information about the connection device among others, and the other four bits of the word specify the number of bits (always a non- ,negative integral power of 2) devoted to each connection device in this block. The device number (see above) is shifted under control of these latter four bits (thus effectively multiplying it) to obtain the relative word address of the connection device information with the block. The relative address is added to the base address referred to the word part of the result being placed in a register specified by two further bits of the second instruction (see above), the address of the device field within the word being retained in the arithmetic unit. A third instruction uses the word part to address the data memory and the field-withinword part to select the connection device information from the word thereby read from the data memory.

Title: Process for the manufacture of concentrated acetic acid
IPC: C07C51/02
Filed: 1923-05-30
Abstract: In the preparation of acetic acid by the interaction of an acetate with a mineral acid, water is added to the reaction mixture in sufficient quantity to permit of the complete liberation of the acetate component, also the distillate from the reaction is collected in at least two fractions, one of concentrated and the other of dilute acetic acid.  Preferably, the concentration of the second fraction is such as to provide the water required in a subsequent distillation, but dilute acetic acid from any other source may be employed.  The distillation may be carried out under reduced pressure and in the presence of a foam-preventing agent such as paraffin, wax or tallow.  The distillates are preferably scrubbed by passing them through a boiling solution of an acetate, to which a foam-preventing agent has been added.  The earlier stages of the distillation may be effected by indirect heating, the reaction being completed by the injection of steam.  The mineral acid for the reaction mixture may also be added in stages.
