Title: New or improved means for applying white lines to road surfaces
IPC: E01C23/24
Filed: 1943-10-12
Abstract: 568,963. Line-markers for roads. COLEMAN & SONS, Ltd., T., and JONES, W. O. Oct. 12, 1943, No. 16748. [Class 132 (ii)] A white line is marked on a road by applying a layer of white-coated grit or like material laid on a coating of tar or other binder and rolled into the surface. An apparatus for applying the white line is embodied in a road-surfacing machine, comprising as usual a wide hopper 10 from which grit or chippings are discharged on to the tarred road through a bottom opening controlled by one or more doors 17 operated by a hand wheel 21, lever 20 and link 19. The wide hopper is divided bv two removable slides to form a central auxiliary hopper containing the white line-'marking grit which is discharged on to the road through a door 25, Fig. 3, normally held open by a spring 27. When marking an intermittent white line, the door is closed at regular intervals by a cam 34 driven from a road wheel 12. For marking a continuous white line, the cam is declutched from the road wheel so as to allow the spring 27 to hold open the door 25. If no white line is required, the cam is declutched, but is left in a position to hold the door closed.

Abstract: 1526912 Text transmission INTERNATIONAL BUSINESS MACHINES CORP 25 April 1977 [7 June 1976] 17018/77 Heading H4P In the transmission of coded text, control signals for printer control are transmitted, using the ordinary text signals. Overall commands, such as "new job", "instructions to be changed", "end", "send", and sent using ordinary text symbols, are recognized as commands by being preceded by the ordinary coding for line end or carriage return, LE, and "comma", so that the code "LE", precedes all overall commands. More specific instructions within such overall commands, such as: positioning of right, or left margins, or top and bottom of format; selection of remote device to receive transmission; holding of transmission link; are recognized by being preceded by the code "LE" alone. Commands and instructions are terminated by the ordinary coding for page end or form feed "PE", whereafter received data is interpreted as normal text. The above approach allows additional commands over and above those normally available in an EBCDIC (extended bcd interchange code) to be communicated without loss or mutilation.
