Abstract: 515,119. Ambulance stretchers. GENERAL AIRCRAFT, Ltd., and WILLIAMS, D. L. H. May 24, 1938, No. 15498. [Class 108 (i)] A stretcher comprises a head or like support in the form of a sling which is maintained above the level of the canvas or like supporting web of the stretcher by means of stout members. The stretcher shown is similar to that described in Specification 488,908, and comprises side rails 10 spaced apart by knuckle-jointed transverse members carrying at the ends supporting feet 12, pins 13 which extend through transverse bushes in the rails 10 enabling the feet and transverse members to be removed from the rails. The rails are accommodated in tubular edge-pockets 15 of the web 14, holes 17 allowing the passage of the pins 13, the heads of which are engaged by tags 18 secured to tapes 19 sewn to the web, the pins thus being retained in engagement with the rails. The sling comprises a canvas band 20 secured at its extremities by sewing and by eyelets 21 to the undersurface of the web and maintained above the web by tubular metal struts 22, the upper end of each of which is cut away to provide lugs 23 to which a channelsection cross-member 24 riveted to the band 20 is pivoted at 25. A pin-fitting 27 at the lower end of each strut is adapted to engage one of a pair of the eyelets 21 in the web. Thus the struts can be removed from the eyelets and folded about the pivots 25. parallel to the web so that the stretcher can be rolled up for storage. The sling may be in the form of a continuous band to which the struts are attached and which is not permanently secured to the web. Alternatively, the struts may be attached to the web and recesses for the pins provided in the,band.

Filed: 1946-05-22
Abstract: 630,011. Indicating-apparatus. EMERY, J. N. May 22, 1946, No. 15498. [Class 106 (iv)] [Also in Groups XX and XL (c)] An instrument for indicating the position of a craft relative to its surroundings comprises means, including two mirror galvanometers, for optically projecting an image representative of the craft on to a screen, and means for positioning the mirror galvanometers in accordance with the co-ordinates of the craft to control the position at which the image appears on the screen. As applied to the radio control of aircraft, an electric lamp 9, whose intensity is controllable by the knurled disc 9a projects a beam of light through a condenser system 10 on to a mirror 11 whence it is reflected on to galvanometer mirrors 15 and 17. The condenser system contains a lantern slide bearing a representation of an aircraft so that an image such as 19 is formed on the screen 3. The lantern slide is rotatable through worm gears 12 and 13 by the Selsyn motor 14 controlled by the aircraft compass so that the image 19 is orientated according to the heading of the aircraft. The galvanometer mirror 15 is controlled by range-measuring apparatus and the mirror 17 by bearing-determining apparatus so that the image is deflected to a position on the screen corresponding to the position of the craft relative to the radio beam. An additional light beam, projected through system 20 containing a slit, is reflected by galvanometer 21 which is controlled by signals measuring height, either from the ground or from a glideplane, to form a line image 23 indicating the height of the aircraft.

Title: Improvements in electrical time switches
IPC: G04C23/22
Filed: 1924-06-30
Abstract: 240,243. Railing, M. J., Turner, H. C., and Sherwin, A. June 30, 1924. Clockwork actuation. - Relates to switches, which may misfunction for an interval, in which clockwork-actuated tappets A, B operate at predetermined times levers C, D to cause a switch arm H first to close and later to open. The lever D is pivoted at d to a link E pivoted to a fixed axis c and an arm F also pivoted at d can move through a small angle relatively to the lever D. The arm H is held against a fixed contact h<2> by a shouldem d<2> on the lever D engaging a projection h<3> on the am H. At a predetermined time the tappet B moves the lever D to the right releasing the arm H which is pulled down by a spring, the projection h<3> sliding along the left hand side of the shoulder d<2>, and the end of the arm F being brought against a stop c<1> on the lever C. At a later time the tappet A moves the lever C to the right causing the arm F and lever D to be moved down till the shoulder d<2> engages beneath the projection h<3>. Then when the lever C is released due to the passage of the. tappet, a spring K pulls the arms D and H back to the position shown in the Figure. Should it be desired that the switch should remain open and not function for a day, the lever F is hooked by hand over the stop C<1> during the previous day. The tappet B will then open the switch as usual but on the following day the movement of the lever C produced by the tappet A will have no effect on the lever F. When however the lever C is released its momentum will carry it past the arm F and the parts are then ready again for normal functioning.
