Points operating apparatus which when set locks whichever points tongue is against its stock rail leaves the other tongue free to move when the points are conflictingly set and trailed, this movement unlocking the closed switch tongue and allowing the points to move under the action of the vehicle wheels. Separate actuating throw bars 14, 15, locking blades 22, 23 and points position indicating members 24 are provided for each tongue of the points. The points are actuated by motor 1 which via gearing 2 rotates a ball screw shaft 3 which co-operates with ball nut 4 to give linear motion to a drive slide 6. Near the mid point of the slide a pair of rollers 10 mounted on the slide each co-operate with one end of a pair of cranks 12, 13 which are pivoted 11 at their knee portion and have their other ends engaging rollers members 16, 17 on the respective throw bars. Locking dogs 20, 21 are secured to the slide and co-operate with notches on the lock bars 22, 23, each bar being provided with a loose and a tightly fitting notch. To shift the points from the position shown in which the upper throw bar 14 is connected to the points tongue which is against its respective stock rail and lock blade 22 which is also connected to this tongue is locked by locking dog 20 entering the tight notch of this blade, the motor is energized and moves the drive slide downwards but because of the shape of the end of the cranks co-operating with rollers 10 no movement is initially imparted to the throw bars, this initial movement serving to move the lock dog 20 out of the tight notch on lock blade 22. Further movement of the slide is now imparted to the throw bars which move the points to the new position, final movement of the slide locking the tongue which is against its respective stock rail by moving dog 21 into the tight notch on lock blade 23. Supposing the points are now trailed when they are conflictingly set, the vehicle wheels close the unlocked open tongue and this movement is transmitted by the associated crank to the drive slide which moves upwardly (the ball nut allowing this movement) and unlocks the locked tongue by moving locking dog 21 out of the tight notch. This action allows the now unlocked tongue to be moved away from its stock rail by the vehicle wheels.

Abstract: 1,166,104. Films. EASTMAN KODAK CO. 29 Sept., 1966 [29 Sept., 1965], No. 43583/66. Heading B5B. [Also in Division B2] A voidless continuous layer of a polymeric film-forming substance is formed on a substrate by applying to the substrate a particulate coating which adheres to or is caused to adhere to the substrate, such coating being porous to vapours of a solvent and applying vapours of a solvent thereto so as to pass through the porous layer and form as a condensate on the substrate surface for a time and to the amount necessary to cause the film-former to dissolve and flow as a liquid first near the substrate and then progressing outwardly until all the pores have been filled, thus producing the voidless continuous layer. The substrate may be preheated, e.g. by contacting its back with a controlled heated mass such as a heat sink. Substrates may be metal, wood, glass, paper and plastic articles. The substrates may be cleaned or pretreated, e.g. primed while the film-forming substance may be adhered to the substrate by electrostatic attraction. In Examples (1) and (6) a cellulose acetate butyrate powder is electrostatically adhered to a steel plate which is then immersed in chloroform vapour for 30 seconds and then in an oven for 30 minutes at 120‹ F.; (2) a hardwood handle is coated with beige coloured cellulose acetate butyrate, immersed in chloroform vapour for 20 seconds after which the process is repeated for a second layer; (3) and (11) glass bottleware is similarly coated with cellulose acetate propionate ester and cellulose acetate ester powder; (4) a phenolic moulded article is coated with blackcoloured cellulose acetate butyrate as in (1); (5) a zinc die-cast automobile horn-ring is similarly coated while cellulose acetate butyrate is used to coat (7) wound paper tubing, (8) an aluminium probe, (9) a casting mould and (10) a film of poly-(1-4-cyclohexylendimethylene terephthalate - isophthalate) wrapped round a 3-inch iron core heat sink. In Examples (12) to (14) steel sheet is coated with methyl methacrylate, polyvinyl chloride acetate copolymers and polyvinyl butyral using both methyl ethyl ketone and chloroform as solvents, with polyvinylidene chloride using tetrahydrofuran, with a polyvinyl chloride acetate copolymer using chloroform vapour to give a priming layer which is then provided with an electrostatically adhered cellulose acetate butyrate porous layer which is treated with chloroform vapours. In Example (15) a layer of cellulose acetate staple fibre (8 denier Î “-inch) is electrostatically adhered to a steel plate heated to 75‹ F. and exposed to acetone vapours at the vaporization temperature of acetone for 20 seconds thus causing the staple fibre layer to dissolve and flow. In further examples a steel plate is electrostatically coated with (16) powdered gelatine or (17) powdered polyvinyl alcohol and subjected to steam at 212‹ F. for 30 seconds.
