Title: Fuel injection systems
IPC: F02M69/22
Filed: 1971-12-15
Abstract: 1363740 Spray carburetters ROBERT BOSCH GmbH 15 Dec 1971 [17 Dec 1970] 58148/71 Addition to 1336606 Heading F1B The fuel injection system claimed in claim 1 of the parent Specification 1336606 is modified in that the distributer valve is a piston movable in the bore of a cylinder, the pressure line connecting to a part of said bore which forms a pressure chamber, via a throttle valve which provides a greater throttle cross-section for pressure fluid in the direction of inflow to the pressure chamber than in the direction of outflow. Plate 2 is moved by the force due to air entering the intake 1, and displaces a fuel distributing valve 11 against a force exerted on the end-face 12 of the valve by fuel in a pressure chamber 34. The fuel reaching the chamber 34 is drawn from the line 17, connected to the output of a fuel pump 15, through a fixed throttle valve 35 and enters the chamber through a port 59, controlled by a throttle valve 57 which includes an axially movable plate 58. The plate 58 has a small central hole 63 aligned with the port 59 and a larger hole 64 off-set from the port 59. When fuel enters the chamber 34 the plate 58 is displaced towards the valve 11 so that fuel flows through both apertures, but flow of fuel in the opposite direction causes the plate to seat against the plate 60 in which the port 59 is formed, so that only the smaller hole 63 is open. The throttle valve 57 prevents the fuel-air ratio increasing at low engine speed, which would otherwise occur due to pulsation in the air supply and in the movement of the plate 2. In a modification Fig. 2 (not shown) the axially movable plate has a triangular periphery, so that when it is displaced, fuel flows around the edges. In a second modification, an apertured reed valve is used, and in a third modification a ball check-valve is used.

The main conveyer comprises a pair of parallel chains 61 which can be lowered to leave the container 52 resting on lugs 63. Containers 52, carrying stacks of coded pallets 51<SP>1</SP>, and themselves coded, are fed to the main conveyer 31<SP>1</SP> at a station 5<SP>1</SP>. A reader R<SP>1</SP> detects whether the workpieces are to be processed on the subconveyer 32a and activates a slope SI and a pusher P1c which pushes the pallets on to the subconveyer. The empty container 52 is then advanced to a stop S2 to receive the pallets from the sub-conveyer. The same applies to the other sub-conveyers. On leaving the sub-conveyer 34a the container is stopped at S7 and the pallets are transferred into a warehouse α in which they are classified by readers R4a-R4d and R5a, R5b. If the workpieces in a container 52 do not require processing on the sub-conveyer 32a, the container is diverted to a by-pass conveyer 31c. If a pallet leaving one of the sub-conveyers, e.g. 32a, carries a defective workpiece, this is detected by a detector, e.g. D1<SP>1</SP>, and the pallet code is altered by a writer, e.g. ml. When the container housing the defective workpiece arrives at S7, the pallets are transferred to the warehouse α, coded, and forwarded to the feeding stations. The containers are fed to the warehouse by a handler M. A warehouse may be associated with each sub-conveyer (Fig. 3).

Patent GB-680007-A (GB)
Abstract: 680,007. Radiators. DRAPER, W. B. Aug. 18, 1950 [Aug. 18, 1949], No. 21501/49. Class 126. In a radiator adapted to be fitted between a combustion stove outlet and a main flue outlet the internal walls of the passages forming the radiator are kept clear of deposited soot &c. by means of scrapers rectilinearly movable therein. As shown the radiator is of sheet metal with passages of rectangular cross-section and is in two parts A, B; each of upstanding M shape. The inlet C and outlet D, adapted for connection to the stove outlet and main flue outlet respectively, are located at the lower apices of the respective M parts which are connected together adjacent their outer feet. Thus the ingoing hot gases, immediately on entry, divide into two upwardly directed streams and follow the dotted path shown to the outlet D. The gases may be made to byepass the radiator by directly connecting the inet and outlet C, D, by opening, by means of a push rod F, a sliding damper E, Each passage of the radiator contains a series of scapers G attached to a rod H which is reciprocated by external manipulation when necessary, and which, for this purpose, may either carry an external handle I or may terminate just short of a removable cap J so that a handle may be easily fitted. At the lower end of each passage is a removable tray K, the trays being interconnected by strips L such that after scraping, the trays may be lowered, after releasing side handles M from clips N, and then slid sideways so that the deposit may easily be removed.
Patent GB-716215-A (GB)
Abstract: 716,215. Ticket-issuing machine. SETRIGHT REGISTERS, Ltd. April 15, 1952, No, 9427/S2. Addition to 676,515. Class 106 (3) The invention as claimed in claim 1 of the parent Specification is modified in that there is a control member and abutment and a group of independently operable quantity control means, the control member and abutment being rotated, on operation of the quantity control means, through varying angles of rotation dependent upon the quantity values of the quantity control means, the control member and abutment being constantly urged for such rotation and released for rotation on operation of the quantity control means. Each of the quantity push buttons 2, Fig. 2, is connected to a bar 22 which is moved to the left on depression of the button until arrested by the adjustable stop 23. A pin 29 on the bar 22 moves an arm 28 to rock the shaft 26 against a spring .68, Fig. 4, so that a cam 27, Fig. 2, frees the control member 11 on the shaft 10 which is then rocked counter-clockwise by the spring 14 until the appropriate one of four angularly displaced arms 17-20 on the shaft 10 engages the recess 24 of the selected bar 22. The motor micro-switch 15 is closed by an arm 13 and the roller 12 on the member 11 leaves the drive pawl 9 which engages the dog 7 so that the drive from the motor 1 is transmitted to the shaft 5. The counter-clockwise movement of the shaft 26, Fig. 4, frees a detent pawl 32 which, however, is at this instant prevented by a pivoted member 42 from engaging a ratchet wheel 30 on the shaft 10. When the shaft 5 rotates an eccentric roller 36 oscillates a rock arm 34 so that a pawl 31 repeatedly engages the ratchet 30 and thereby returns the shaft 10 step-by-step, in accordance with the number of tickets desired, to the initial position. The detent 32 prevents reverse movement of the ratchet 30. For every revolution of the shaft 5 the selected ticket printing and feeding mechanism is operated as described in the parent case. When the shaft 10 reaches its initial position it is again locked by the cam 27, Fig. 2, and the roller 12 engages the pawl 9 to release it from the dog 7. The micro-switch 15 is opened by the arm 13 before the completion of the last machine cycle but a second micro-switch 50, Fig. 2, in parallel with the switch 15 remains closed until the end of the cycle when a cam 54 on the shaft 5 allows a bar 52 to move to the left so that a blade 53 frees the switch plunger. A rod 56 extends across the machine and carries four arms 55 each of which normally enters a notch 57 in one of the bars 22 to prevent depression of the associated button 2 until, by depression of a value key, not shown, the rod 56 is allowed to move clockwise, Fig. 2, and raise the arms 55 from the bars 22. As in the parent Specification an inertia absorbing stop device is provided for the drive mechanism.
