Title: Improvements in or relating to means for fastening together two plates or any two members
IPC: F16B21/06
Filed: 1945-08-09
Abstract: 601,530. Casting-machines. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. Aug. 9, 1945, No. 20445. Convention date, July 11, 1941. [Class 83 (i)] [Also in Groups XVIII and XXV] Moulds ; cores.-Means for fastening together two plates or any two members so that they are positively located with respect to one another, comprises two or more elastically deformable pillars integral with one plate or member and each provided with an angular projection adapted to engage in a recess or groove in the other plate or member. As shown in Figs. 1 and 2, elastically deformable pillars 1 and 2 integral with a plate 8 are provided at their top ends with shoulders 3 and 4 and projections 5 and 6 by means of which a plate 11 is fixed. The tendency of the pillars 1 and 2 to separate presses the projections 5 and 6 against the adjacent surfaces of the recesses 31 in which they engage. The pillars 1 and 2 may be modified, Figs. 4 and 8 (not shown). The injection mould for making the above plate 8 with the integral pillars 1 and 2 is shown in Fig. 3 and comprises a base 13, a body 18, a closure plate 12 carried by a movable press plate, not shown, and an ejector member 14. The mould is extracted by moving the plate 12 and with it the body 18 and member 14 to the right, so moving the plate 8 from the base 13. The member 14 then abuts a stop 15 and its feet 21 hold the plate 8 during the continued motion of the plate 12. The projections 5 on the pillars 1 and 2 then hold the body 18 against movement. When the blades 16 of the plate 12 disengage the pillars 1 and 2, feet 17  of the plate 12 engage the body 18 and carry it to the right so releasing the plate 8. A spring 20 returns the parts 18, 12 and 14 to the position shown. In another embodiment, Figs. 14 and 15, the elastically deformable pillars are arranged round the peripheral edge of the plate 8, each pillar 1 having a projection 5 and being between two rigid pillars 9 and 10 which have shoulders 23 and 24. In this case the injection mould is of simpler form, Fig. 23, and comprises a base and body 13, a closure plate 12 and an ejector member 14. The mould is extracted as before by movement of the member 14 and plate 12 to the right then stopping the member 14. A return spring is again provided.

A fuel injection apparatus comprises a diaphragm 12 one side of which is in communication with an injection nozzle 14 through a fuel feed conduit 13, the other diaphragm side being in communication through a pressure conduit 10 with a pressure generator 3 which pumps mercury therethrough at at least 6 m/sec whereby when a shut-off device 11 is opened the mercury is pumped through the conduit and when the shut-off device is closed a pressure wave is transmitted through the diaphragm to the conduit 13 so that fuel is ejected from the nozzle. Operation. With the shut-off device 11 open mercury in tank 1 is pumped by gear pump 3 through non-return valve 5, filter 6, to the conduit 10 and returns to the tank 1 via the return conduit 15. When device 11 is suddenly closed a pressure wave is transmitted via the diaphragm 12 to the fuel present in the conduit 13 thereby injecting a quantity from nozzle 14. The volume displaced from conduit 13 is replenished from tank 16 via pump 18 filter 20 and non-return valve 21.
