Title: Improvements in or relating to machines for marking on roads and other surfaces
IPC: E01C23/20
Filed: 1935-01-26
Abstract: 449,964. Line-markers for roads &c. TURNER, R., 25, Brownberrie Avenue, Horsforth, near Leeds. Jan. 26, 1935, No. 2623. [Class 132 (ii)] A line-marking machine for roads or other surfaces comprises a receptacle for a marking medium which is passed to a jet or spray by a force feed device, and a rotary printing pad adapted to make intermittent rolling contact with the ground for impressing the marking medium thereon. The marking-wheel 4 is mounted between a pair of arms projecting forwardly from the tank 1 carried on ground wheels 2. A portion of the periphery of the marking wheel carries a projecting marking pad 8, and the rolling surface of the wheel is completed by cam rings or flanges 9, or alternatively the marking pad may extend round the whole circumference of the wheel. The paint or other marking material is drawn from the tank by a pump on a shaft 19 and passed through a pipe 14 to a jet 15 close to the marking wheel. The jet orifice may be made to open and close under the control of a runner in contact with one of the cam rings 9. A fixed brush may smooth the paint on to the marking wheel. The pump may be driven by a power unit or by gearing from the axle 3 of the ground wheels and may be automatically thrown into and out of action to treat correctlv the marking portion 8 of the marking-wheel. This automatic action comprises a friction clutch on the pump shaft moved in and out of operation by a cam 24 and lever 22, a stationary friction brake preventing over-running. An idler wheel 29 carried on an arm 30 may be swung on to the ground to raise the marking wheel when the machine is to be moved without marking. When greater spacings are required between the intermittent markings than is afforded by the rotations of the marking-wheel, the idler wheel 29 is moved into position by a hand lever, or by automatic means comprising a rod 36, lever 35, roller 34 and a cam 31 actuated by gearing from the axle 3. The cam 31 may be thrown out of driving connection with the axle to render the idler wheel 29 inoperative, by displacing a spring-loaded pin. When the cam 31 raises the marking wheel, a second cam 37 actuates a trip lever 39 which in turn moves the hand lever 22 to cut-off temporarily the feed of paint. Alternatively, instead of employing the cam 37, the trip lever 39 may be pivoted to the lever 35. A shrouding plate 40 attached to the arm 30 catches paint dripping from the marking wheel when raised. A rotary brush 41 sweeps the ground in advance of the marking wheel. The machine may be provided with propelling handles 46 or may be propelled by a power unit. In a modification, the jet 15 sprays the paint on to the ground in front of the marking-wheel. When the marking pad 8 extends round the whole periphery of the wheel a continuous line may be made on the ground by disengaging the cam 31 and allowing the pump to work continuously.

Patent GB-981926-A (GB)
Title: Method of preparing liquid and dried egg
Inventor: SPICER ARNOLD
IPC: A23L15/00
Filed: 1963-01-22
Abstract: To liquid egg there is added an emulsifying agent consisting of a mixture of at least one mainly hydrophilic emulsifier and at least one mainly lyophilic emulsifier in aqueous emulsion to promote and stabilize in the liquid egg the oil-in-water emulsion formation whilst at the same time promoting and stabilizing the water-in-oil emulsion formation in dried egg prepared therefrom. Hydrophilic emulsifiers: Mono glyceryl esters e.g. glyceryl monostearate and glyceryl mono-oleate or the polyhydric alcohols e.g. propylene glycol.  Lyophilic emulsifiers: Glyceryl di-esters such as glyceryl di-oleate, and sorbitan di-oleate.  The emulsifying agent preferably includes also an intermediate emulsifier having fairly balanced hydrophilic and lyophilic properties.  Intermediate emulsifiers: Polyoxyethylene derivatives such as polyoxyethylene sorbitan mono-oleate, and sorbitan di-acetyl tartaric acid.  The emulsifying agent which is used in the proportion of from 45 to 107 g. added to 13.5 Kg. of liquid egg, should contain 35-80 parts of the mainly hydrophilic emulsifier(s), 8-25 parts of the mainly lyophilic emulsifier, with or without 2 parts of an intermediate emulsifier. According to an example, 65 g. glyceryl monostearate (self emulsifying) and 20 g. glyceryl di-oleate are melted together, 2 g. polyoxyethylene sorbitan monooleate and 5 g. propylene glycol are mixed in, and then 800 mls. water at just below its boiling point are added with rapid stirring.  The mixture is then cooled with constant stirring until a smooth creamy emulsion is produced.  This emulsifying agent is then added slowly with constant stirring (but sufficiently gentle to prevent aeration of the egg) to 13.5 Kg. of mixed liquid whole egg until a smooth, completely homogeneous emulsified liquid egg results.  This emulsion is then pasteurized at a temperature not in excess of 60 DEG C., poured on to shallow trays to a depth of about 1 inch to 1 1/2 inches, frozen to about -40 DEG C. and then dried under vacuum.  The following observations are made: The glyceryl monostearate and propylene glycol have the effect of reducing the crystal size of the frozen block so that the amount of heat necessary for removing the water from the frozen mass can be reduced while the propylene glycol is comparatively powerful in preventing removal of water of crystallization during drying, thus preserving the mono-nuclear layer of moisture in the dried product and promoting rapid and ready re-hydration of the dried product.  The liquid and dried egg products may be employed in cake making.
