Abstract: 856,693. Pistons. NORTH AMERICAN AVIATION Inc. Aug. 11, 1958, No. 25717/58. Class 122 (1). [Also in Groups XXVIII and XXIX] In a radial cylinder pump or motor the pistons each comprise a piston and slipper assembly 10. The piston portion is thinwalled and of steel and has a spherical portion 40 engaging the cylinder bore; secured within the piston is an aluminium plug 44 which forms with the piston a passage 46 so that liquid from the cylinder may flow through a non-return valve 49 to a lubrication basin 47 within the slipper portion 12 which has a spherical portion 13 engageable with the track ring 5. Differential expansion between the plug 44 and the piston reduces the passage 46 when the temperature of the pump and liquid increases. A groove 52 is also formed between the piston and plug 44 so that liquid pressure expands the piston into contact with the cylinder. The piston surface may also flatten under load to increase the area of contact with the cylinder bore.

Abstract: 1306530 Cups CROWN MACHINE & TOOL CO 28 May 1970 [28 May 1969] 25720/70 Heading A4A [Also in Division C3] A substantially rigid thin-walled cup for use in a vending machine is made from fused-together expanded synthetic plastics beads and has a hygroscopic coating on its exposed surfaces. The synthetic plastics beads are coated with a hygroscopic agent which permeates through the walls of the cup when the beads are heated in a mould thus forming the hygroscopic film. This film reduces the build-up of static electricity on the cup. The preferred synthetic plastics and hygroscopic agent are polystyrene and a detergent e.g. a modified aluminium or ammonium lauryl sulphate and an organic amide builder. The preferred wall thickness and cup weight are between 0À03" and 0À05" and below 4 grams respectively.

The condition (6) must be satisfied in this arrangement. The light-source in the alternative path may be mounted on the same post as the main lamp, or may serve as a pilot light.

Sleeve 13 and pin 20 can then function as a hinge for the window. Downward pressure on the catch releases pin 20, and also imparts an opening impulse to the window by engaging an extension 26 of the catch with sleeve 13.

Filed: 1948-10-05
Abstract: 661,671. Control of two D.C. motors. FORD MOTOR CO., Ltd. Oct. 5, 1948. [Dec. 3, 1947] No. 25917/48. Class 38 (iii). [Also in Group XXXV] Automatic arc welding apparatus in which the welding electrode is fed by a motor energized from the main welding circuit, the feed motor being energized after a time delay, and a resistance being inserted in series with the motor armature to limit the speed at which the electrode is advanced to strike the arc. On closing the push button 16, relay 30 closes to start the carriage feed motor 29, and accelerating relays 31, 34, close after suitable delays. Simultaneously, relay 17 closes to short circuit resistor 18 in the field of exciter 19 to provide full output from the welding generator 10. After a delay to allow the voltage of generator 10 to build up, relay 23 closes to energise the electrode feed motor 22, which is a series motor connected in series with a speed limiting resistor 24 across the output of the welding generator. When the arc is struck, the voltage across a shunt 28 in the arc supply line closes relay 27, shorting out the speed limiting resistor 24 to allow normal regulating operation of the feed motor 22. Relays 17C and 30C (in parallel with relays 17 and 30) are also energised from the shunt 28 so that on shutting down (by releasing push button 16), the generator output and carriage feed are maintained until the arc is extinguished. In a modification, Fig. 2, (not shown) a voltage sensitive relay starts the electrode carriage motor when the generator output has built up, and the electrode motor speed limiting resistor is normally short circuited by a relay which opens to place the resistor in circuit when the generator voltage is above the normal welding voltage (i.e. before the arc is struck). As an alternative, in either embodiment, the electrode feed motor may be separately excited, with the armature across the welding circuit. A further time delay relay, Fig. 3 (not shown), also energized when push button 16 is closed, energises a solenoid to retract the electrode assembly to assist in striking the arc. Alternatively, a relay energized by the welding current shunt 28 may control the solenoid. In a further modification, Fig. 4 (not shown), a current/voltage relay closes to short circuit resistance 21 in the exciter circuit as the voltage builds up, and opens when the welding current flows. This provides a very heavy starting current to initiate the arc.
