Aerials ; directive signalling. - Comprises various modifications of the directive aerial systems described in the parent Specification. (1) A pair of aerials, each comprising alternate horizontal and vertical sections half a wave-length long, are arranged one above the other in one plane as shown in Fig. 5. Alternatively, one of the aerials may be moved sideways half a wavelength to bring adjacent horizontal sections opposite each other (Fig. 4, not shown). Energy is fed from the two poles of a high-frequency source to the points at which the aerials are nearest together. Two aerial pairs such as that shown in Fig. 5 may be set up in parallel planes a half wave-length apart (Fig. 6, not shown). (2) The aerial conductor is bent in three dimensions to form an interconnected set of parallel aerials, as shown in Fig. 7. (3) As shown in Fig. 8, the vertical aerial sections are divided into three portions 1, 2, 3 each half a wave-length long, separated by coils 4, 5 each equivalent to half a wave-length, so that current is in phase in the three vertical sections. (4) Two such aerials, having only two portions and a single coil in each vertical section, may as shown in Fig. 9, be placed one above the other in the same plane. Specification 272,117 is referred to. In the Specification as open to inspection under Sect 91 (3) (a), Fig. 10, (Cancelled), shows the aerial formed as a spiral, each turn of which comprises substantially a square figure the sides being half a wave-length long. This subjectmatter does not appear in the Specification as accepted.

Title: An oil burner apparatus
IPC: F23D11/00
Filed: 1958-09-03
Abstract: 850,202. Photo-electric burner monitoring. CLEAVER-BROOKS CO. Sept. 3, 1958 [Sept. 6, 1957], No. 28279/58. Class 40(3). [Also in Group XI]  In a circuit for controlling an oil burner, a room thermostat 87 and a manual switch 81 are closed to connect power supply wires 107, 113 to a transformer 90 which energizes a relay winding LR to close contacts LR1 to energize the starter relay 84 for a motor 25 driving a combustion air fan and a fuel oil pump, to energize a timer motor 82, to energize an ignition transformer 77 and to energize a fuel valve 58, supplying a pilot burner (not shown). The flame of the pilot burner is sensed by a photo-cell 78 which energizes a flame relay FR to close contacts FR-1 to complete partially a circuit to a fuel valve 59 supplying the main burner (not shown). When sufficient time has elapsed for the fan to attain a speed sufficient to supply air necessary for the main burner the timer motor 82 closes contacts 95 to energize a relay winding 102 which closes contacts 97, 99 and, later, opens contacts 96, 98. The contacts 99 close a holding circuit for the relay winding 102 and the contacts 97 complete the circuit to the main fuel valve 59 so that the main burner is supplied with fuel which is ignited by the pilot burner. The contacts 98 open to deenergize the timer motor 82 and the ignition transformer 77. The contacts 96 open to break the circuit to the pilot fuel valve 58 but the valve is maintained in open condition by energization through the flame relay contacts FR-1. If no flame is established at the pilot burner before the timer motor 82 closes the contacts 95, the contacts FR-1 will be open and the main fuel valve 59 will not be energized and the pilot fuel valve 58 will be de-energized by the contacts 96. Limit switches 85, 86 are included in series with the room thermostat 87. A safety switch operative on failure of flame relay FR to de-energize relay LR and thus de-energize the entire circuit may be included.

Abstract: 213,879. Measurement, Ltd., (Assignees of Compagnie pour la Fabrication des Compteurs et Materiel d'Usines a Gaz). April 4, 1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Induction-motor relays; protective arrangements. - A return current relay for alternating currents has two windings F, G, Fig. 3, the winding G being traversed by the current 1<1>, in the line to be protected and the winding F being traversed by the current I<2> in a neighbouring circuit which is not reversed by the fault in the protected line, and is operated by a couple which is a function of I<1>, I<2> cos (I<1>, I<2>); or currents dependent on I' and I<2> may be used. The electromagnet E of the relay acts in known manner on a rotatable blade H, so that normally an arm L tends to abut against a stop J but on the occurrence of a fault it rotates to close conbacts K to operate a circuit-breaker. For protecting feeders in parallel, Fig. 1, a relay is placed in each feeder A or B at a point remote from the generator G and the winding F of each relay is traversed by the current in the common wire leading to the receiving station R. In the case of looped nets, relays are placed in each line at both ends of the loop. For arrangements such as that shown in Fig. 4, in which feeders a, b, c are connected to a bus-bar U. the windings F of the relays R', R<2>, R<2>, protecting the feeders a, b, c are traversed, by a current obtained by connecting in parallel the secondary windings of transformers T<2>, T<4>, T<6> inserted in the lines 1, 2, 3; or alternatively the current for the windings F may, by suitable parallel connections, be the resultant of the secondary currents of the transformers connected to the feeders.
