Title: Coating process
Inventor: GREEN WILLIAM
IPC: B05D7/16
Filed: 1962-01-15
Abstract: Metal springs (as defined) are coated by a process comprising the steps of treating the metal springs with a solution of silicone oil-modified alkyd resin composition in a chlorinated hydrocarbon solvent (e.g. trichloroethylene and perchloroethylene), substantially removing the solvent from the film formed on the metal springs and curing the residual film on the metal springs by heating (e.g. 200-270  DEG C.).  The terms "springs" is defined as including complete spring assemblies, e.g. spring frames for mattresses, seats and upholstery.  In the example, a wire spring unit was passed through a composition comprising trichloroethylene, polydimethylsiloxane and dehydrated castor oil/glycerol phthalate alkyd resin, the solvent was then removed in an extraction system and then the spring was stoved at 270  DEG C.

Title: A tractor, more particularly for towing ordnance or other heavy vehicles
IPC: B60K17/28
Filed: 1953-01-21
Abstract: 721,810. Operating clutches. DOORNE, H. J. VAN. Jan. 21, 1953 [Jan. 28, 1952]. No. 1812/53 Class 80 (2). [Also in Group XXX]. In a winch of the type set out in Specification 464,384, [Group XXX], a toggle-mechanism 43-46 (Fig. 3) is provided, the toggle being spring pressed by a spring inserted in the winch coupling and being connected (by slot 40) to pawl 29 so that when the pawl locks the draw hook of the tractor, the spring moves the toggle to disengage the coupling. As shown (Fig. 3), handle 32 operates pawl 29 against its retaining spring 27 through the medium of linkage 33, 35, 36, 28, and handle 49 operates the winch coupling fork shaft 11 through the medium of linkage 51, 52, 53, 54, 46, 45. The two linkage systems are coupled by toggle 46, 43 and by pin-and-slot linkage 40, 39, 37. In operation the operator swings handle 32 to the right so as to pull pawl 29 to the left and so release the draw hook, and, owing to the pin-and-slot 40-39, this movement has no effect upon the shaft 11 so that the coupling connected to the latter remains uncoupled. Then the operator swings handle 49 to the right so that toggle 46-43 swings to the left and couples the coupling to drive the winch and let out the drawhook. Again, when the drawhook is pulled in, it releases pawl 29 which moves to the right, which movement, through linkage 37, 41, swings the toggle back over to the right and disengages the coupling and therefore the winch drive. The two handles 32, 49 may be combined into one handle which operates both systems of levers. The coupling operated by rotation of shaft 11 is shown in Fig. 1 and consists of a clutch member 9 which slides along splines on driven shaft 4 so that its teeth engage or disengage the teeth of driving shaft 2. Member 9 carries sleeve 20 which slides on the said member 9, the pin 22 of member 9 engaging slot 21 of sleeve 20 and abutment 25 fixed on member 9 limits this movement of sleeve 20. Two springs influence, the two movements, thus disengaging spring 19 is positioned between the casing and sleeve 20, and engaging spring 26 is positioned between sleeve 20 and member 9. The clutch is operated by rotation of shaft 11, the shaft moving sleeve 20 by engagement of legs 13 with disc 16 secured on the sleeve so that whether the clutch is engaged or disengaged, the shaft 11 is subject to the influence of one or both springs, whereby the toggle joint of Fig. 3 is held at either of its extreme positions.

Abstract: 1412833 Direct positive photographic silver containing image production AGFA-GEVAERT AG 15 Jan 1973 [15 Jan 1972] 1985/73 Heading G2C Direct positive photographic images are produced by imagewise exposing a photographic material comprising at least one uniformly fogged direct positive silver salt emulsion layer with imagewise elimination of the developable fog followed by development, the fogged and developable direct-positive silver salt emulsion layer having a degree of fogging and a silver salt concentration such that when the unexposed layer is developed with the developer used for developing the exposed layer, maximum densities of between 0.02 and 0.8 are obtained, and treatment of the developed material with a peroxide compound (i.e. a compound which contains the peroxo grouping) which is decomposed at the positive silver image, the positive silver image then being intensified either physically by development of a vesicular image superimposed on the positive silver image (see Exs. 1 and 2) or chemically by an oxidation reaction with colour producing reactants, e.g. colour couplers, to produce a dye image superimposed on the positive silver image (see Exs. 3-5). The fogged and developable direct-positive silver halide emulsion layer may have (i) a degree of fogging of up to 70% and a silver halide concentration of 1-6g silver in the form of silver halide per m<SP>2</SP>, or (ii) a degree of fogging of 70-100% and a silver concentration of 0.02-0.5g per m<SP>2</SP> in the form of silver halide. These emulsions are extremely sensitive to light, but have such a low concentration of fogged silver halide grains that normal processing would only result in direct positive images with insufficient image densities.

Abstract: 337,293. Ceskomoravskß-Kolben-Danek Co., and Kostßl, J. Jan. 21, 1930. Stop-gear.-A safety device comprising a valve in the fuel supply of an internal-combustion engine is held in the open position by the lubricating.oil pressure and also by the pressure of the starting-air through a system of cylinders and pistons. Before starting the fuel valve is opened by a hand lever by partial displacement of one of two pistons. When the oil and air pressures become operative, the hand lever becomes inoperative. The fuel valve 1 is pressed down by a spring 2 and is arranged above the safety-gear case 5 which comprises coaxial cylinders 6, 7 secured in position by a cap 10 and housing pistons 8, 9 respectively, which are actuated by oil pressure supplied by a connection 16 and air supplied by a pipe 17. The piston 9 is pressed down by a. spring 15 and has a head 14 which controls the contacts 18 of an alarm. A lever 11 is secured to a toothed plug 12. On moving it to the horizontal position, the piston 9 is partly raised to open the valve 1, and the contacts 18. The pressure of the starting-air completely raises the piston 9. releases the lever 11 which falls to the vertical position, and presses the oil piston 8 against the cap 10. If the oil pump does not immediately supply pressure oil after the starting of the engine, the engine stops after the stoppage of the air, and the alarm signal is operated. An opening 20 in the cylinder 6 allows leakage oil and air to escape to a pipe 21. A modification is described wherein the oil and air pistons are secured to the fuel valve spindle on opposite sides.

Class 80 (2) A pulley unit of the type described in the parent Specification is modified by arranging each of the flanges 1, 3, Fig. 1, of the pulley at one end of a cylindrical barrel 2, 4, the barrels telescoping one within the other and being connected by a key 5 preventing relative rotation between them but allowing axial movement, and by fixing a spindle 6 to the end of the outer barrel 4, the spindle rotating in a bearing 7 the non-rotating outer race 8 of which is connected to a guide bar 9, Fig. 3, by which the axial position of the outer barrel is controlled. As shown, the pulley is keyed to the shaft 12 of an electric motor 11 mounted on a machine slide having undercut engagement with an angularly set guideway 16 in the motor base 13, and is traversed along this guideway by rotating a handwheel 18 having a screwed spindle 17, the limits of this motion being determined by set screws 16a. The guide bar 9, to which the non- rotatable bearing housing 8 is secured, is mounted in grooves 19 on the two arms 20 of a bracket 21 adjustably mounted on an arm 24 of the base 13, so that the grooves 19 can be raised and lowered to disengage them from the bar 9, and the latter arranged in the approximately correct angular position with respect to the base 13, to match the inclination of pulley flange 3. Means are provided for effecting the final fine angular adjustment of the bar 9. The basic spacing of the pulley flanges may be controlled to compensate for belt stretching &c. either by adjusting the position of the motor 11 axially relatively to the base plate, or by adjusting the length of the arm 24 as by making the latter separate from the base 13 and introducing packing between the two parts. The invention can also be applied to a countershaft unit of the type described in the parent Specification.
