Class 38(5) A polyphase overload protective device has a shaft.25 biased for rotation in one direction under the contol of an escapement 34, 35 which releases the shaft for rotation in response to the operation of any one of the overload responsive elements 38 in the respective phases, rotation of the shaft causing the opening and subsequent reclosing of all the contacts 17, 18 in the respective phases, limiting means preventing further rotation of the shaft after the contacts have been opened a predetermined number of times: The moving contacts are spring loaded bridging contacts 18 carried on insulating arms 19 mounted on a shaft 20. Fixed on the shaft 20 is a crank arm 22.having a slot within which rides a pin 23 carried by a crank arm 24 on the shaft 25 so that one revolution of the shaft 25 causes the opening and reclosing of the contacts. Movement of the shaft 25. under the bias of a torsion spring (not shown). applied through gearing (indicated at 26) is normally prevented by a pin 34 on a lever 33 secured to the shaft 25 engaging an abutment on a spring biased escapement lever 35. In the event of overload, any of the bimetallic elements 38 may engage the associated adjusting screw 43 on the lever 35 and move the lever to the right so as to release the pin 34. The shaft is then rotated until the pin 34 engages the end of the left hand side of the U-shaped lever 35, the contacts being opened. On the cooling of the bimetallic strip or strips, the lever 35 is moved to the left by its biasing spring 36 ana the pin 34 is released from the left hand end of the lever 35. The shaft 25 is rotated until the pin 34 re-engages the abutment an the right hand limb of the lever 35, the contacts being reclosed. This sequence is repeated a number of times before the contacts are locked open by a pin on the gearing abutting a fixed member (not shown). The contacts 17, 18 may be connected in the high voltage side of a transformer and the bimetallic elements in the low voltage load side of the transformer (Fig. 7, not shown), the various parts of the device being arranged on a common base 16 for mounting below the oil level in the transformer tank. A resetting shaft (not shown) may be provided with a resetting lever which indicates the position of the contacts and the number of operating sequences which have occured.

Abstract: 935,183. Blow moulding hollow articles. OWENS-ILLINOIS GLASS CO. March 15, 1960 [March 25, 1959], No. 9034/60. Class 87(2). In a method of making a hollow plastic article by forming a tube of plasticized material and blowing the tube to its final shape in an enclosing mould, the pest of injecting a gaseous medium into the tube prior to its enclosure in the mould to radially expand the unconfined tube to a configuration conforming generally to the configuration of the final article. An apparatus shows an extrusion machine 21 with a piston operated by pass 51, a piston closing device 42, 43, extrusion head 30, head mould 36 and blow mould 61. In operation, material is extruded to injection mould a head in the head mould 36, device 42 descends to prevent extrusion of further material and the extrusion pressure forces down a piston 55 of the by pass 51 to allow recirculation of the plastic material. The device 43 is then forced down simultaneously with the raising of head mould 36 to extrude a tube integral with the moulded head of the article. As the head mould rises it actuates a cam-switch device 71, 72 to admit air to the interior of the tube to expand it radially before the mould 61 is closed and final expansion at a higher pressure takes place. The pre-expanding of the tube may take place during different stages of the tube extrusion for the moulding of different shaped articles, Figs. 2, 6, 8 (not shown), the tube may be pre-expanded more than once to produce " waisted " articles, Figs. 14, 15 (not shown) and, if the shape of the article (e.g. oval) demands that the pre-expanded tube has a major dimension greater than the minor dimension of the mould, the pre-expanded tube may be collapsed and " pleated ", before insertion in the mould, by release of pre-expansion pressure and further raising of head mould, Fig. 12 (not shown). Specification 809,534 is referred to.
