Abstract: 927,686. Charging and clearing sludge beds. NORSTEL & TEMPLEWOOD HAWKSLEY Ltd. Feb. 27, 1962 [May 4, 1961], No. 16190/61. Addition to 892,572. Class 78 (4). Instead of sludge-digging apparatus being mounted on the travelling gantry C 2  as in the parent Specification, it is mounted on a support carriage D 4  which normally moves with the gantry but which can be separated from it to move from one sludge bed to another. As illustrated, the carriage D 4  can be withdrawn on to a traverser 46 by which it is moved laterally between the several beds served by the gantry C 2 . The gantry and the carriage are driven by pinions 40, 51, engaging racks such as 37 and driven by motors 42, 50 synchronized so that the gantry and carriage normally advance together. The sludge-digging conveyer 52 is constructed as described in the parent Specification, and can be raised by a cable 55 and winch 54 to clear the walls 67 of the sludge beds when the carriage D 4  is to be withdrawn on to the traverser. The digging conveyer 52 delivers to a conveyer 72 which in turn delivers to an elevator 74 by which the sludge is carried to a conveyer 43 mounted on the gantry.

Title: Pendulum support switch for automotive anti-creep device
IPC: B60T11/10
Filed: 1953-06-12
Abstract: 745,077. Hydraulic brakes. GAYLORD PRODUCTS, Inc. June 12, 1953 [June 14, 1952], No. 16253/53. Class 103 (1). In an anti-creep device for automobiles of the kind in which the brake cylinders are maintained pressurized by the energization of a solenoid-operated valve unit 10 after the brakes have been actuated by master cylinder 7, the circuit to the solenoid includes in series between the battery 68 and an earth 62 a pressure operated switch 43 closed whenever the brakes are pressurized, a mercury inertia switch 65 carried by a pendulum arm 12 which opens to interrupt the circuit in the event of acceleration or deceleration of the vehicle, and a switch 60 which is closed only when there is no pressure on the accelerator pedal 2. The pendulum arm 12 is pivotally supported on a shaft 49, Fig. 3, and is clamped against the overhanging end of a housing 41 by a piston 48 moved to the left by fluid pressure in the hydraulic line when the master cylinder 7 is actuated, so that the pendulum arm 12 is locked in its hanging or truly vertical position according to the gradient on which the vehicle is standing; the end part 74 of the arm 12 may, however, be adjusted to a position slightly out of the vertical for setting the switch by means of a bolt 75 with calibrations 76 that may be adjusted against an index mark 77. Under the system described, the solenoid valve 10 will be energized to hold the brakes on so long as (a) the accelerator pedal 2 is not depressed to open switch 60, (b) the brakes are not pressurized by the pedal 5 thus closing switch 43, and (c) there is no substantial acceleration or deceleration of the vehicle which would cause opening of the mercury switch 65. Under any other conditions the solenoid holding valve will not operate. The use of the pendulum arm 12 together with the plunger 48 for locking it in its hanging position enables the mercury inertia switch to operate correctly whatever may be the gradient on which the vehicle is standing. In modifications described, the circuit is altered so that the solenoid 10 is energized through a relay and there are a pair of mercury switches pivoted to the end of the arm 12 secured angularly to act for each direction of swing of the arm.

Abstract: 1,030,367. Screen printing; transfers. WILKS. April 15, 1965 [April 21, 1964], No. 16467/64. Heading B6C. In a screen printing process a transfer having a design printed in extroverted or negative form is applied to a screen and screen printing ink is applied to the screen to produce the design on an article in opposite form to the printed design of the transfer. The transfer is printed in an ink which is insoluble in the screen printing ink used and is preferably a reacted plastic resin in which the reaction partners are either cross-linked at ambient temperatures or catalysed under applied heat. Where the reaction partners are cross-ticked the ink may be either an acid cured polymer of acrylic, alkyd, epoxy, phenoxy, phenol, polyamide, polyester, polyether, polystyrene, polyurethane or polyvinyl resins or modified polyester/alkyd copolymer resin reacted with a polyisocyanate. Examples given of inks having catalysed reaction partners are a melamine, polyamide, polyethylene or urea resin. The reacted plastic ink of the transfer design may be opaque, translucent or clear, but, in use, practical advantages are gained by a tinted but translucent cross linked ink The transfer may be of the water slide or direct application type. In the latter type the design is printed directly on to the temporary backing without the intermission of an adhesive as is found in the water slide type
