Patent GB-575070-A (GB)
Title: Improvements in means for protecting electrical direct-current installations againstreverse currents
IPC: H02H3/18
Filed: 1944-02-24
Abstract: 575,070. Protective cut-out arrangements ; induction relays. AKT.-GES. BROWN, BOVERI, & CIE. Feb. 24, 1944, No. 3473. Convention date, March 12, 1943. [Class 38 (v)] A reverse-current protective arrangement for a d.c. system employs a three-winding transformer the primary and secondary of which are normally uncoupled bv saturating' the core in the normal direction by the third winding energized by a constant d.c. voltage. When the main current reverses the core is desaturated and the secondary energizes a signal or trip relay. As applied to a mechanical converter in which supply leads 15 are connected to a load over contacts 13 driven by a motor 14, each lead 15 includes the primary 2 of a transformer 1 having a polarizing winding 3 connected to a d.c. source 10 so as to saturate the transformer-core in the direction of the main current in 2. The series-connected secondaries 4 supply a relay-coil 6 with a current-impulse when, on reversal of the main current, one of the transformer-cores is desaturated. The impulse induces in a closed coil 18 an e.m.f. which reacts with a polarizing flux set up by windings 7 so as to rotate the contact 19 into a position in which it shortcircuits all the leads and is latched at 20, 21. The windings 6, 7 are distributed each to a pair of poles of a four-pole magnet. In a three-phase arrangement of Graetz-connected valve-rectifiers, each supply lead is connected to the mid point of the corresponding primary so that the core is magnetized in the same direction by the go and return currents. In this form the protective relay has a holding winding for maintaining it closed after the trip-impulse has passed, this winding being independently energized and de-energized by a manual switch for resetting purposes. The polarizing winding circuits of the transformers and the relay holding circuit include chokes to prevent induced currents therein, Fig. 4 (not shown).

Abstract: 938,469. Shoe sole moulding and vulcanising machines. C. I. C. ENGINEERING Ltd. Feb. 1, 1960 [Feb. 4, 1959], No. 3991/59. Class 87(2). A shoe sole moulding and vulcanising machine in which the mould is withdrawn at a controlled rate to effect a slight increase in the volumetric capacity of the moulding cavity during the moulding and simultaneous vulcanisation of a shoe sole composed of microcellular rubber employs a control unit for controlling the displacement of the ram driving the sole mould comprising a piston biased to a normal position wherein closure is effected of an orificed member coupled to the ram, this biasing action being relieved by connecting the piston to a control element having the required displacement consequent upon operation of the sole mould cylinder unit to cause controlled fluid flow from this unit and hence to effect a smooth translational movement of the sole mould. One form of control unit described includes a centre valve body 1 having a top cover 2 in screw threaded connection with the tail 127 of the ram of a sole mould cylinder unit and provided with a transversely extending passage 7 communicating with the discharge side of this ram. Passage 7 also communicates with the bore 10 of the body 1 and the exhaust port 14 via the orifice 8 in a plug 9, which orifice is sealed by the piston 11 being forced upwardly by the biasing spring 12. The head 16 of a piston rod 15 is slidably received within a socket 17 in the piston 11, the rod 15 extending through the bottom plate 3 of the valve body 1 for attachment to an inextensible tape 89 clamped to a cam-rocked beam (not shown) for downward movement upon withdrawal of the sole mould. As the piston rod 15 is lowered, the washer 20 on which rests the piston 11 is also lowered and consequently the orifice 8 is opened. Electrical warning of override in opposite directions is provided by means of the contacts 30, 31 which are normally open, excess movement of the piston rod 15 or of the valve body 1 resulting, through the intermediary of a lever 25, slidable plunger 23 and cross bar 27, in the closure of one or other contact. In a modification, the piston rod 15 is made more sensitive by opposing the biasing action of spring 12 by a lighter spring partially accommodated in a vented socket formed in the upper face of the piston head 16. Specification 897,587 is referred to .

Abstract: 1527204 Preheating combustion air G C BROACH and D W THURMAN 1 Feb 1977 [9 Dec 1976] 04040/77 Heading F4B In a heating furnace hot gases generated by a burner 14 and combustion air pass through a convection section 16 to a stack 18. A stream of fluid circulating in an adjunct loop 20 from a parent stream 22, is heated in a coil 34 by the combustion gases and the heat collected is transferred by a device 30 to a coil 36 for preheating combustion air passing to the burner. A pipe 24 interconnects the adjunct loop 20 to the parent stream 22 and supply of fluid to the adjunct loop is induced by a restriction 26 in the parent stream. Expansion and contraction of fluid in the loop 20 is compensated for by flow in either direction in the pipe 24. A second pipe 28 having a valve 32 may connect the adjunct loop to the parent down stream of the restriction 26. In normal operation the valve 32 is closed, but in the event of breakdown of the device 30 the valve 32 is opened and a portion of fluid stream 22 is allowed to flow through the pipe 24 and the adjunct loop 20 to prevent overheating of the coil 34.
