Abstract: 1485230 Feeding wires; making electric leads AMP Inc 20 Oct 1975 [26 Nov 1974] 42955/75 Headings B3W and B3A In the feeding of wires 32, 34 from reels 36, 38 to a device 12, such as a crimping tool, pressure is applied to a selected wire by, e.g. rollers 110, 112 to increase its length by forming a loop in it before both wires are cut between the reels and the location of the loop. At the start of a feeding step wires pass through guides T2, T1 and an open reciprocable clamp E and are clamped by a clamp B on a movable carriage A which holds a support D for guides T1, T2 fully retracted against the action of a spring S. As the carriage moves towards the device 12, releasing the support D, the rolls 110, 112 form the loop BL in wire 32. The carriage A is advanced almost to the device 12, the clamp E is closed and a blade assembly F is moved laterally of the wires into cutting position. Blades 534 sever the wire while insulating-cutting blades 538 cut through the insulation on the trailing ends of the cut wire leads and the leading ends of the wire stock. Moving the carriage to its fully advanced position and retracting the clamp E strips the severed lengths of insulation. The clamp B is lowered relative to the carriage A to deposit the leads in open barrel terminals projecting, e.g. from an electromagnetic coil bobbin 42. Crimping dies (44), Fig. 7 (not shown), are lowered, the clamp B is raised to a position higher than that of Fig. 1 and the blade assembly F is moved out of the feed path. While the carriage A is being retracted the rollers 110, 112 are returned to their initial position and the clamp E is closed and advanced to feed the new lengths of wire. The clamp B is lowered, the carriage A is moved to retract the support D against the spring S and the clamp B is closed to grip the wires for a new cycle.

Abstract: 1,270,485. Hydropneumatic suspension units with automatic level regulation. AUGUST BILSTEIN. 14 Sept., 1970 [25 Sept., 1969], No. 43848/70. Heading F2S. In a hydropneumatic suspension unit with automatic level regulation, a closed liquid containing circuit consisting of a reservoir 10, a pump 14, a regulating valve 13 and a pressure chamber 19 regulates, through a displaceable separating element 15, the pressure in a gas chamber 6 which controls the pressure of the working liquid in the working cylinder 1, and thus the height of the unit. The pump 14 is driven by an electric motor 11 actuated by a switch (not shown) responsive to the height of the unit to pump liquid from the reservoir 10 to the pressure chamber 19 where it acts on the gas in chamber 6 which in turn pressurizes the working liquid in the reservoir chamber 18 which communicates with the working cylinder 1. The same level-responsive switch alternatively operates an electromagnet 12 to open the regulating valve 13 and exhaust liquid in the pressure chamber 19 to the reservoir 10. In Figs. 2 and 3 (not shown) the gas chamber 6 is in two parts which intercommunicate by a narrow passage. One part is pressurized by the liquid pressure chamber, and the other part pressurizes the reservoir for the working liquid. The narrow passage delays level regulation. In Fig. 3 the diaphragm 15 is replaced by a floating piston (24). The regulating liquid has a viscosity which is indepdent of temperature.
