Title: Improvements in and relating to electrical duct or trunking
Inventor: BALDWIN PETER JOHN
IPC: H02G3/04
Filed: 1954-10-26
Abstract: 746,367. Conduits. MARRYAT & PLACE, Ltd. Oct. 26, 1954, No. 30884/54. Class 36. Trunking for a distribution system comprises a rectangular-section casing 1 divided by partitions 2 into a number of ducts 3 to receive conductors 4, slots 10 being provided at intervals along the casing which are normally closed by cover strips 11 which are slidable in grooves 5 provided in the casing and which are bowed so as normally to be retained in position over the slots 10. Each strip 11 may be provided with a projection 12 and a rib 13 which normally engages the slot 10. To make a tapping the projection 12 of the appropriate strip 11 may be gripped to straighten the strip and disengage the rib 13 from the slot 10, when the strip may be moved along the casing to expose the slot.

Title: Aircraft ejection seat mechanisms
Inventor: AXENBORG CARL EVERT
IPC: A22B3/08
Filed: 1969-06-18
Abstract: 1280321 Aircraft ejection seat apparatus SAAB-SCANIA AB 18 June 1969 [19 June 1968] 30895/69 Heading B7G A seat ejection mechanism has a single operating arm 39, Fig. 2, moved one step at one end by a pilot-actuated link 42 and one step at the other by a cable 24 actuated by cockpit canopy release, each step alone merely taking up lost motion in a pin-and-slot connection 40, 41 between the arm 39 and a firing mechanism catch 38 to that both steps are necessary to move the catch 38 and release detent balls 36 restraining the spring-loaded firing pin 32. If canopy release does not occur, the linkage 42 can be moved a further step sufficient to effect firing pin release. Each arm of the pilot's seat has a projecting handle 9, Fig. 1, which is raised into a position locked by a spring 14 to effect the first step of the linkage 42 by carrying into view a concealed handle 12, which, via a pull lever 16, a splined connection 17, 19 (to allow seat length adjustment) and a helical pin-and-slot connection to a push rod 18, actuates the link 42. Such action also initiates canopy release via a switch 20 which energizes both a gas-cartridge operating the canopy lock 23 and gas-cartridges operating canopy ejectors 22. The lock cartridge is also energizable by a manual plunger 24. Subsequent canopy opening about a pivot 5 actuates the cable 27. Should canopy release not occur, the handle 12 is gripped and raised further to effect the further step of the link 24. An eye 44 prevents undue movement of the cable 27 and a spring loaded catch 46 prevents the arm 39 dropping after canopy release. In a second embodiment (Fig. 5, not shown) breaker pieces (55, 58) are incorporated to ensure a minimum pull on the members 27, 42 before they move the arm 39, the lost-motion connection between which and the catch 38 is a ball-and-groove one (41, 64). A plunger (51) is also incorporated in the catch 38 which effects release of further detent balls (48) normally locking the ejection seat and firing mechanism to the aircraft floor and which is operable manually or by downward movement of the catch 38. A safety lock arm (66) is provided which can be moved to prevent raising of the ram 39. The catch 46 is replaced by a locking pin-and-slot mechanism (45, 62) biased by a plastic slider (63). In other embodiments, the lost-motion connection between the members 38, 39 comprises a sun-planet-annulus epicyclic gearing (Figs. 11 to 13 not shown) and a rotary coupling (Figs. 14 and 15, not shown)

Disc, wheel, and roller apparatus.-A portable rotary tool comprises a fluid pressure turbine which drives a tool-spindle through reduction gearing, the turbine having a number of nozzles and a hand controlled valve for regulating the speed by admitting fluid to one or more nozzles in sequence. The turbine which is of the Stumpf type and is enclosed in a casing 12 eccentrically mounted on a gear casing 13, consists of a rotor 16, Fig. 2 in the periphery of which are formed, for instance by milling, semi-circular buckets. The drive is transmitted from a pinion 21 on the rotor shaft through a triple reduction gear consisting of a wheel 22, pinion 24, wheel 25, another pinion and a wheel 28 on the tool shaft 29 which carries a drill, but double or single reduction gearing may be employed. A screwed cup 19 serves as an adjuster for the rotor shaft and also as a lubricator. In one form of controlling valve shown in Fig. 4 fluid enters at 30 from a hose and proceeds through a passage 43 to the interior of a plug valve 32 connected to a handle 31 which may be rotated between the limits of stops 45 so as to bring one or more or a set of staggered ports 47, 49-51, in communication with ports 48, 52 - - 54, each of the latter being connected to one of a number of approximately tangential nozzles formed radially outside the rotor in a plate secured to the casing 13 and co-planar with one edge of the rotor. In a modification the nozzles may be formed in the flat base of the valve casing 33, or in the plate 11 of the gear case. An adjustable shield (not shown) may be provided to cover an exhaust opening formed in the casing 12.
