Title: Process for electrophoretic coating or lacquering of metal parts
IPC: C09D5/44
Filed: 1967-03-02
Abstract: A metallic object, particularly a moving aluminium strip having surface oxide film for transformer construction, is electro-phoretically coated or lacquered by immersion in an aqueous lacquer bath comprising a synthetic resin diluted or emulsified in water at 27-32 C. at an electrode voltage of 118-155 volts and with the distance between the electrode and the object being 35-115 mm to simultaneously round-off sharp edges and de-burr. The synthetic resin is preferably free of ammonium and alkali and alkaline earth metal cations, and may be an oil-modified phthalate or alkyd resin. A lacquer additive such as finely powdered or precipitated filler e.g. SiO 2 or CaCO 3 , and/or a non-hydrolyzing aid e. g. a Mn naphthenate or an octoate may be present in the coating bath. The lacquer in the bath is preferably circulated, and any adhering mechanically to the object after its emergence may be washed off and then the coated object stoved e.g. at 200-220 C.

Title: Lamp Failure Warning Circuit
IPC: H05B37/03
Filed: 1967-11-15
Abstract: A lamp failure warning circuit comprises a plurality of series circuits each including a resistor 13, 13a . . ., and a lamp 14, 14a . . ., e.g. the lamps on a road vehicle, the junction of the resistor and lamp in each circuit being connected to operate warning apparatus in the event of any one of the lamps failing. When a lamp fails, its respective diode 16, 16a . . . conducts to switch off transistor 17 and hence switch on transistor 22 and illuminate warning light 23. Further means may be provided, as shown, to indicate failure of the warning light: the currents provided to warning light 23 and further light 23a through 24, 25 and 24a, 25a are normally insufficient to illuminate the lights, but should one of these lights fail, the associated diode 27 or 27a conducts to switch off transistor 17 and switch on transistor 22 and thus illuminate whichever of lamps 23, 23a is still intact. The circuit of Fig. 3 (not shown) is modified to monitor the stop lights, in addition to the other lights, of the vehicle.

Title: Non-actuated inertial brake
IPC: G06K13/077
Filed: 1968-07-31
Abstract: A body, e.g. a document, moving along a feed path 12 to a work station 17 is arrested by a brake mechanism 20 comprising a brake mass 35 extending at an acute angle across the path and adapted when struck by the body to absorb the kinetic energy in the body by substantially vertical movement. The brake 35 may be positioned by a leaf-spring 36 such that it rests in contact with path 12. In an alternative form, Fig. 2, the brake mass may comprise a freely mounted roller 46 resting in contact with feed bed 43 and whose vertical movement is limited by member 50. In a further form (Fig. 4, not shown), a vertically movable roller is mounted beneath a lower feed surface and protrudes therefrom to abut an upper feed surface between which surfaces the document is fed. The roller is held in its raised position by a yieldable spring. The brake may arrest documents, being fed from stack 10 by feed rollers 13 and 14, before they reach work station (e.g. punch) 17. The arrested sheets are moved forward by actuation of roller 22 to press against driven roller 23, thus pushing the sheets beneath the brake. The sheets are delivered by rollers 31 to stacker 33.
