Patent EP-0093615-A1 (EP)
Inventor: KALMAN GABOR
IPC: H02P5/74
Filed: 1983-05-03
Abstract: Variable speed rotary electrical machines, specifically induction motors and motor drive systems. A main induction motor (15) and an auxiliary induction motor (17) have respective stators (21) housed in a common housing (19) and have respective rotors (23, 27) which are electrically concatenated and mounted on a common shaft (29). The main stator (21) is supplied with a constant a.c. voltage by a main inverter (35) connected to a constant-voltage d.c. link (45,47, 43) and the auxiliary stator is supplied with a variable a.c. voltage by an auxiliary inventor (37) which is forced-commutated and connected to a variable-voltage d.c. link. 
     A controller (40) controls the gating of the inverters (35, 37) and enables the forced-commutated inverter (37) to supply an a.c. signal of selected frequency and voltage level to the auxiliary stator such that a prescribed reactive power will be coupled through the auxiliary and main rotors (27, 23) to the main stator (21) to cause the latter to appear to constitute a leading power factor load, permitting the main inverter (35) to be line-commutated and supplied from a substantially constant voltage d.c. link. Alternatively, a drive system may comprise a plurality of the machines each with a main motor and an auxiliary motor. The stators of the main machines are all supplied from a single common main inverter which is line-commutated and the stators of the auxiliary machines are separately supplied from separate forced-commutated auxiliary inverters.

Abstract: An electromagnetic valve comprising a housing (10) having fluid containing region (14,16) and first (18) and second ports (20) in communication with the region, an electromagnet (70) carried by the housing located external to the fluid containing region of the housing, and a barrier in the form of a thin diaphragm (80) of fluid Impermeable material which hermetically isolates the electromagnet from the fluid chamber. An armature (110) in the housing is movable within a body (90) of magnetically permeable material and has a pole portion (114) located for magnetic attraction by the electromagnet and has a valve portion (140) located for opening and closing one of the ports (18) to place the ports (18,20) in fluid communication through the housing region (14,16) in one control state of the valve and to block fluid communication between the ports through the housing region in another control state of the valve. The armature is moved from a rest position through a forward stroke when attracted by the electromagnet to change the control state of the valve, and the armature is moved by a biasing spring (130) in an opposite direction through a return stroke back to the rest position. A magnetic circuit is defined including the electromagnet (70), a portion of the fluid-impermeable barrier (80), the body (90), the armature pole portion (114) and a gap defined between the pole portion and the electromagnetic and located in the fluid containing region (16) of the housing and external to the electromagnet which . gap is closed during movement of the armature toward the electromagnet during energization thereof. The valve is made electrically and magnetically efficient by minimizing the total gap within the magnetic circuit, by having the pole face area (116) relatively large on the armature pole portion (114), and by having the electormagnet include a coil (74) or a core (72) of relatively small diameter.

Abstract: Polymeric cladding for elongate substrates, preferably electrical conductors, comprises an inner layer and an outer layer, the outer layer being a cross-linked polymer composition filled with halogen-free particulate inorganic flame- '  retardant filler which has been treated with material which increases the elongation to break of the composition at 200°C to at least 50%. The enhanced elongation enables the cladding better to resist burning, possibly by reducing the tendency for the outer layer to split when exposed to fire. Bundles of insulated electrical wires may be wrapped in mineral tape, preferably mica tape, to provide circuit integrity cables which are significantly smaller and/or lighter than previously known.

Abstract: A safety harness has an eyelet (13) which is threaded with a safety line (10) fixed at both its ends with a safety hook (11,12) which is sized so as not to be able to pass through the eyelet (13). In normal use one hook (11,12) is attached to a life-line, or a load-transfer device engaged therewith. When two persons attached to the lifeline wish to pass, the other hook (12,11) can be clipped onto the life-line beyond the attachment at the time being of the person to be passed followed by subsequent release of the first hook (11,12). Such an arrangement obviates the need fortwo lanyards to accomplish such a passing manoeuvre. A resilient housing (14) may be located on the eyelet (13) for stowing the hook (11,12) not in use at any particular time.

Abstract: A modular cast concrete element (5) capable of being assembled with other, similar elements into a tubular underground installation (e.g. sewer duct, tunnel liner) has a well (14) opening to each of its axially-facing end surfaces (78) wherein a rod (15) is received that is insertable in a like well in an axially adjacent element to guide one of the elements to a predetermined position relative to the other and lock it in that position. In each well is a tubular retainer 18 containing a securement member (16) having an annular radially outer marginal portion (14) confined in a circumferential radially inwardly opening groove in the retainer and having resilient radially inwardly projecting teeth (25). The teeth have radially inner edges on a circle of smaller diameter than the rod (15) and are flexible axially to enable the rod to be easily inserted into the securement member but to engage it under convergent bias for holding it against withdrawal from the well. Each retainer (18) can be assembled from commercial plastic pipe fittings or may be formed from injection mouldings.
