Abstract: 1379966 I C engine fuel injectors; regulating engines W KRAUS 20 July 1972 [23 July 1971] 34057/72 Heading F1B Hot gas, which is at least mainly combustion air, is supplied to a zone adjacent the outlet of a fuel injection nozzle 1 at a mean flow rate, which at most amounts to one third of the combustion air fed to the engine at idling, the gas being heated by a device 26, e.g. an electric resistance heater, independent of the engine. The operation of the device 26 may be controlled by a regulator 30 in accordance with the hot gas temperature and the speed and the oil or cooling water temperature of the engine. The device 26 may be operated to provide a hot gas temperature above 150 degrees, possibly fuel ignition temperature, at starting with the device being switched off above a certain engine speed, e.g. 2000 r.p.m. The hot gas temperature may decrease with increase in engine oil or cooling water temperature. The hot gas may be supplied to the device 26 by an electrically-driven blower 28, an exhaust gas operated injector or engine suction and the gas may enter the space 20 around the nozzle 10 through a tangential opening 18. An apertured baffle plate 38, Figs. 2a and 2b (not shown), may be located around the nozzle 10. A part 14a defining a Venturi at the outlet 24 of the nozzle 10 may be movable in accordance with the position of a throttle valve (52), Fig. 7 (not shown), in the engine intake conduit (50), the flow cross-section between the part and nozzle being largest when the throttle valve is closed. An additional electrical resistance heater (42), Fig. 4 (not shown), may be provided at the Venturi throat. The casing 14 surrounding the nozzle may have a converging portion downstream of the Venturi throat and upstream of the outlet, Fig. 5 (not shown). The hot gas may enter the chamber 20 through a plurality of bores (50), Fig. 6 (not shown), which direct the gas substantially radially into the chamber but which may have axial and tangential components. The nozzle 10 may produce two or more fuel jets which meet a short distance from the nozzle outlet 24. The hot gas may contain exhaust gas and combustion catalysts. The described method of fuel supply is stated to be particularly suitable for rotary piston engines. The hot gas may be supplied continuously or intermittently in phase with intermittent operation of the injection nozzle 10.

Title: Collating machine
IPC: B65H39/105
Filed: 1961-09-25
Abstract: 946,975. Collating sheets. R. G. LOWE, and B. S. FORNELL. Sept. 25, 1961 [Nov. 18, 1960], No. 34169/61. Heading B6H.  Sheets delivered from a printing machine are collated directly in a plurality of pockets 57 in a rotatable drum 32. The sheets are fed by means of endless tapes such as 55 over guide plates 46, 47 and 48 or 49 depending upon the position of a deflector 50. The pockets 57 are moved step-by-step past the end of the guide plate 49, the drum 32 being alternately driven in an anti-clockwise direction by intermittent drive means and braked. A sheet leaving the plate 49 and entering a pocket 57 engages a feeler which actuates a switch S and the switch initiates rotation of the drum. The rotation is arrested by the engagement of a detent on the drum with a further switch, such engagement occurring when the next pocket 57 is aligned with the plate 49. In the event of a crumpled sheet keeping the switch S closed the drum is automatically prevented from rotating through more than one step until the crumpled sheet is removed. A counter on the printing machine is set so that the printing machine stops after printing a given number of identical sheets, e.g. sixty. The drum has fifty pockets all of which need not be used. A second counter is set to the number of collated sets of sheets required, e.g. forty. After forty identical printed sheets have been delivered into forty individual pockets of the drum the second counter moves the deflector 50 to its broken line position and the remaining twenty sheets are deflected over the guide plate 49 into a removable tray 33. The deflector can also be controlled independently of the counter, being pivoted to the broken-line position when the operator presses a " reject " button. When all sixty sheets have been printed the operator changes the plate on the printing machine and prints a further sixty sheets from the new plate, of which sheets the first forty are deposited in the forty pockets 57 previously used. This process is repeated until the complete book or the like has been printed. The collated sheets in the pockets 57 are removed therefrom by hand and placed as shown at 99, 100 in Fig. 3, in a trough mounted on the collating machine. The trough has sides 96, 97 and is inclined so that the sheets abut against a base 98. Sheets are retained in the pockets 57 as the latter are inverted during rotation of the drum by an arcuate retaining strip passing round the lower portion of the drum. If no spare copies are required the tray 33 need not be used. The apparatus may be used as a simple, non-collating sheet receiving device by fixing the deflector 50 in its broken line position.
