Title: Improvements relating to reciprocating-piston internal combustion engines and methods of operating the same
IPC: F02B3/00
Filed: 1962-04-25
Abstract: 973,120. Fuel injection systems. GESELLSCHAFT FUR LINDE'S EISMASCHINEN A.G. April 25, 1962 [April 25, 1961], No. 15705/62. Headings F1A and FIB. In an engine in which the main portion of the fuel is injected by a pump into the transfer passage connecting an auxiliary combustion chamber to the main combustion chamber, the pressure conditions in the transfer passage during injection and the flow resistences in the fuel pipe between the pump and transfer passage are such that the pump operates without imposing any substantial pressure on the fuel. The pump has a main plunger 1 which initiates the main injection through passage 12 when it enters the part of cylinder 14 above a recess 15, and an auxiliary plunger 2 which co-operates with a spring-loaded plunger 5 to produce a preliminary injection through passage 6 at a constant pressure determined by the loading of plunger 5. The passage 6 may join the main injection passage 7, which opens into the transfer passage through a valveless nozzle, or the passage 6 may lead to a separate injection nozzle in the transfer passage or auxiliary combustion chamber. In the initial movement of plunger 1, plunger 2 is raised to compress the fuel in space S and lift plunger 5 to open passage 6 for the preliminary injection, the main injection beginning when plunger 1 has traversed recess 15. The passage 12 has a lightly loaded non-return valve therein.

Title: Ground-effect machine moving along a track
IPC: H03F3/54
Filed: 1971-05-19
Abstract: 1337633 Air cushion vehicles BERTIN & CIE 19 May 1971 [20 May 1970] 15853/71 Heading B7K A ground effect machine travels along a fixed track 7 with the aid of cushions 1-6, 10 and 11-17 which are resiliently connected to the machine structure 18 in such a way that the forces transmitted thereto by consecutive cushions decrease from "master" cushions 1, 11. The connexions are effected by "balloons" 19-25, 27-32; pressurized fluid is supplied to balloons 21, 19 corresponding to the cushions 1, 11 and from these to each of the other balloons in sequence with balloons 25, 30 and 28, 32 being connected to atmosphere whereby the pressure in any balloon is smaller in proportion as that balloon is further from the balloon 1 or 11. On straight track the daylight clearance is least for the cushions 1, 11 which serve to guide the machine; on a curve cushion 5 (as shown) is the first to move towards the track, and its pressure increases. Balloon 25 is then compressed so that some clearance is retained, the increased pressure in this balloon being transmitted to the other balloons in sequence as far as balloon 21. Thus the force transmitted to the structure is spread along the cushions and local stressing is avoided. The connection between the balloons need not be between adjacent balloons, and the pressure differences between the individual balloons or between balloons 1 and 11 need not be the same. The cushions need not be arranged symmetrically of the "master" cushions.

Title: Baggage handling system
IPC: B65G47/50
Filed: 1972-04-06
Abstract: 1384593 Baggage conveyers RAPISTAN Inc 6 April 1972 15968/72 Heading B8A A baggage handling system for use in an airport comprises baggage containers 60 carried by conveyers, e.g. conveyer belts and roller conveyers, the system also including a bag checkin area 20, coding and despatching units 22, a storage area 28, a softing and dispensing station 30, and a slide 33 on which bags are discharged from the containers 60 for loading on carts 36 for carriage to a plane. For dealing with baggage on carts 38 from a plane, after identifying information on the baggage check is coded into the system by a coding unit 22a, the baggage is loaded into a container which is carried by a conveyer 40 to a switch 42 where, if no demand has been made for the baggage, it passes, via a conveyer 44, to the storage area 28. If a baggage check is submitted to a baggage call unit 48 at a claim area 46 and the check is cleared, the container is sent directly to the claim area or, if it is in storage, is called from the area 28 and sent to the claim area by a high-speed conveyer 49. If the call is made before a container reaches the switch 42 via the conveyer 40 the container can be switched to conveyer 50 for immediate delivery to the claim area. Containers emptied in the claim area are either returned to the loading area for deplaned baggage or moved to the check-in area 20 for reuse. A computer is used to control the system, Fig. 14 (not shown). A simplified system, Fig. 31 (not shown), has no computer but includes a code reader (503) and a mechanical or electronic selector (504). This system is manually supervised. Containers 60, Fig. 5, each comprise a foursided tray having a door 68 hinged at 70 and provided with a latch mechanism 72 at both sides. The door is released when a solenoid 96, Fig. 7, in the path of the container at a discharge station engages a finger 92 connected to the mechanisms 72. Discharge, e.g. at the claim area 46, is arranged by inclining the conveyer and the container. There may be doors at both ends of the container and to close these, a camming device is secured at the side of the conveyer. For a container having a different latch mechanism as in Figs. 15-17 (not shown), the door is opened by a solenoid operated trigger (133), Figs. 19, 20 (not shown). To spread the discharge of the baggage across the width of the claim area 46 a number of the triggers (133) are actuated one by one. Similar operation of the latch mechanisms 72 is provided by movement of the solenoid across the claim area. The system of Fig. 1 is controlled by a conventional computer having, storage banks and means for compariing coded information fed thereto with the stored information. Each container has a plate 361 on which is impressed a code, either magnetic or optical, which is also supplied to the computer.  At check-in, the baggage is associated with a check 400, Fig. 26, for use with the computer and for use by the claimant at the destination.
