Title: Improvements in and relating to the moulding of materials by injection
IPC: B29C45/72
Filed: 1941-08-19
Abstract: 551,468. Injection-moulding thermoplastic substances. GRAFTON, H. Aug. 19, 1941, No. 10572. [Class 87 (ii)] A process wherein material is transferred by a piston from a preliminary cylinder into the injection cylinder, from which it is extruded by a piston through a nozzle into the mould, is characterized in that the material is transferred by subjecting it to a pressure higher than the extrusion pressure and the transfer is effected through an opening which is of smaller cross-section than the preliminary cylinder and is of such dimensions that the material is subjected to substantial preliminary heating by being forced through the opening into the extrusion cylinder, whereafter the material is heated to the extrusion temperature and extruded into the mould. This preliminary heating may be supplemented by external heating. Fig. 1 shows apparatus suitable for carrying out the invention. A piston 8 forces material from a preliminary cylinder 7 through a channel 11 in the injection piston 6. A ram 3 ascends to close the mould and then telescope the injection cylinder 5 over the injection piston. In Fig. 4 the two pistons are shown at rightangles and the material is fed to the preliminary cylinder in the form of a rod 20 which passes through a heated channel 18 ; this preheating and feeding arrangement may be combined with the process illustrated in Fig. 1. The preliminary feed and the injection feed may be interlocked electrically, mechanically, or hydraulically to ensure that retraction of the preliminary piston cannot occur during the injection stroke ; alternatively, the preliminary piston may operate independently and at a higher speed than the injection cylinder. The apparatus of Specification 501,277 may be used in performing the invention.

Title: Device for the mechanical locking and unlocking of closed elevator doors
IPC: B66B13/20
Filed: 1974-03-11
Abstract: 1457617 Lift cage and shaft door control LINDEN-ALIMAK AB 11 March 1974 [9 March 1973] 10672/74 Heading B8L Closed elevator doors 7, 8, 6 at holding floors 4, 5 and on cage 1 are mechanically locked and unlocked by a locking mechanism 9, 10, 11 located at the door and including a locking bolt movable to a locking position by a spring and movable against the spring into an unlocking position by an electro-magnetic coil actuated by an electric circuit. The coil is arranged to be actuated by lock actuators 12, 13 associated with each door and operated by a lock actuation device 14 carried on the cage, when the cage is stopped at a holding floor. Movement of the locking bolt from its door locking position causes a break in an electric circuit controlling movement of the cage, whereby the cage cannot be moved unless the door bolt is fully locked, and also the bolt cannot be fully locked unless the door is fully closed. The lock actuator device 14 comprises an electro-magnet which upon energization at a holding floor influences magnetic switches associated with the lock actuators on the cage and at that holding floor, causing energization of the locking bolt withdrawal magnetic coils and associated interrupting of the cage drive circuit. In further embodiments, Figs. 5, 6 (not shown) the door lock actuators 12, 13 may be energized due to mechanical switches actuated directly by a movable actuator on the cage, or due to magnetic switches activated by a permanent magnet movable on the cage between effective and ineffective positions. In the embodiment of Fig. 7 (not shown) the lock actuator device 14 of the first embodiment causes the removal of a ferromagnetic disc from between a permanent magnet and a magnetic switch of the door lock actuators. In a final embodiment, the door look actuator includes a light activated switch for association with a light source on the cage.

IPC: A21C7/01
Abstract: 108,034. Embrey, L. July 22, 1916. Dough dividing and working machines; rolling - machines. - Dough is moulded or shaped by coiling it under tension, then passing it through a preliminary shaper adapted to roll it into substantially cylindrical form, delivering the shaped dough to a prover and, after proving, passing it through a second or final shaper. Pieces of dough are delivered to a coiling-apparatus 35 of the type described in Specification 11724/14, from which they pass to a cylindrical shaper 36 comprising oppositely-moving bands 37, 38. The shaped pieces fall into pans 6 of a prover 1 of the type described in Specification 107,829, [Class 78 (i), Conveyers &c.], which delivers them to a suitable cottage &c. moulder. To synchronize the movements of the prover conveyer 28 with the delivery of the dough pieces from the shaper 36, the conveyer is driven through a one-revolution clutch mechanism 51 controlled through a Bowden wire 42 by a lever 41 fitted with a flap 40 which is deflected by the pieces of dough as they are discharged from the shaper 36. The clutch mechanism comprises a continuously-rotating ratchet 49, Fig. 5, loosely mounted upon a shaft 50 which drives the nrover conveyer, the shaft 50 being furnished with a disk 51 carrying a pawl 52 normally held out of engagement with the ratchet 49 by a lever 55 connected to the wire 42. Upon actuation of the wire, the lever 55 is tripped, allowing the pawl 52 to engage the ratchet 49. After one revolution, the pawl is again disengaged by a cam projection 53 riding up the lever 55 and the disk 51 is held by a catch 61 engaging a notch 62. The dough pieces. after proving, may be delivered to a conveyer 31 and again passed through the coiling-apparatus 35 and shaper 36 Fig. 8 shows a further modification in which the dough pieces pass from the conveyer 23 to a band 67 which delivers them either to a final mould 68 or, via a laterally-displaceable band 71, to a second coiling-apparatus 72 and shaper 73. The pieces of dough may be elongated before passing through the apparatus by means of a former 75 comprising a pair of belts similar to those of the shaper 36 but wider. Specifications 126/14 and 22308/14 also are referred to.
