Abstract: 1288176 Seat belts W D KLINK 27 May 1971 [29 May 1970] 17650/71 Heading A3V [Also in Division F2] A device for absorbing energy, which is incorporated into an inertia reel device for storing a vehicle seat belt, comprises a sleeve 18 on which the seat belt is wound, the sleeve being carried at one end on a portion of square cross-section 19 of a torsion bar 20 contained within the sleeve and secured at the other end in a toothed wheel 21, the torsion bar being rotatably carried in a bracket 22 secured to the vehicle, the toothed wheel becoming locked at the onset of an emergency such that withdrawal of the belt against the action of a return spring 23 is then possible only by torsional deformation of the torsion bar 20 which thus absorbs energy and counteracts the force on the belt acting on the wearer. The device causing locking of the toothed wheel at the onset of an emergency comprises a locking lever 25 having one end pivotally mounted in recesses in the bracket 22 and its free end in the form of a ball socket resting against a ball 26, and a spring 27 which holds the lever 25 in its rest position but is adjusted relative to the mass of the ball 26 such that at a predetermined acceleration or deceleration or change in the attitude of the vehicle the ball moves relative to the bracket 22, thus causing the lever 25 to be lifted such that the toothed wheel 21 is locked by one or more projections on the lever. In an alternative embodiment the torsion bar is contained within a sleeve to which it is non-rotatably connected at one end, the other end of the torsion bar being connected to a flange in turn non-rotatably connected to one side plate of a bracket secured to the vehicle, the sleeve being rotatably mounted in the side plates of the bracket such that any withdrawal of belt from the sleeve causes deformation of the torsion bar. Alternatively the torsion bar may be contained within a sleeve to which it is non-rotatably connected at its middle by means of a portion of square cross-section engaging a similarly shaped constriction in the sleeve, the ends of the torsion bar being attached to flanges non- rotatably connected to the side plates of a bracket secured to the vehicle. A further alternative embodiment provides for the torsion bar to be incorporated into a device which need not be secured to the vehicle and comprises a torsion bar contained within a sleeve to which one of its ends is non-rotatably connected, the other end of the bar being connected to a flange non-rotatably connected to one side plate of a holding device comprising two side plates non-rotatably connected together by means of two pins, two free ends of the seat belt being passed from the sleeve round respective pins such that any pull on the belt causes the belt to bear against the pins and deform the torsion bar.

Abstract: 860,792. Lenticular   photographic film. KODAK Ltd. June 4, 1957 [June 8, 1996], No. 17816/57 Class 98(2) A lenticulated film base 'has on the side opposite to the lenticles a sensitive silver halide emulsion layer containing an ethylene oxide polymer consisting of a polyethylene glycol or a condensation product of ethylene oxide with an organic compound having an active hydrogen .atom, the ethylene oxide polymer having a molecular weight of .at least .300. Such film may.be developed after exposure to give images of satisfactory definition and sharpness without the necessity of using an ammonia developer, 'the use of which is objectionable '.because of its odour and .because of evaporation during processing which makes control difficult. Thus a silver bromiodide emulsion .containing 1 gram of 'the condensation product of 1 mole of oleyl alcohol with 25 moles of ethylene oxide (polyethyleneglycol oleyl ether) per mol of silver halide may be coated on a lenticulated support, exposed therethrouh, developed .in a hydroquinine developing solution, bleached with acidified dichromate, cleared with sodium bisulphite, re-exposed, developed in a metol-hydroquinone developer and fixed to produce a positive. Sharpness can be improved by incorporating a substituted amine in the first developer, and for this a developer comprising metol, hydroquinone, sodium sulphite, potassium bromide and cyclohexylaminopropanol is exemplified. For processing to a negative the first developer only may be used. The ethylene oxide polymers may be made by the processes of Specifications 380,431, 380,851, 548,019, 592;676 and 600,058. Other substituted amines for use in the first developer are quoted.

Abstract: 255,496. Morse, W. G., (Assignee of Bundick, C. U. and Proctnr. B..4.). July 18, 1925, [Convention date]. Kinematograph apparatus. - In apparatus wherein the film is fed from one carrier to another under the control of means operated by the tension of the film, the parts are disposed in close relationship so that the unwound film is short and extends over a path which is mainly straight and has no acute bends. As shown, a film 7 passes from a feeding reel 2, through a gate 6, over an intermittent sprocket 9 to a take-up reel 3. An arm 13. pivoted at its end 14, and having a fixed or yielding guide 20 engaging the film, is pulled by an adjustable spring 16. The arm 13 carries a brake shoe 18 engaging a drum 15 rotating with the reel 2. and the pressure is adjustable by a stop 19. When the film is fed, its tension causes the shoe 18 to be moved slightly from the drum 15, but the movement is preferably insufficient to disengage the shoe from the drum. The take-up reel 3 is also provided with a drum co-operating with a brake shoe 23 carried by an arm 21 pivoted at its end 22 and having a fixed or yielding guide 25 engaging the film. The reel 3 is driven through a friction clutch, and increase in the film tension below the sprocket 9 increases the brake pressure and reduces the speed at which the film is taken up. The gate may comprise two sections, one carrying guiding wheels 8, and the other the intermittent sprocket 9.
