Title: Improvements in electric circuit controlling means
IPC: H02H7/26
Filed: 1923-10-23
Abstract: 226,910. British Thomson-Houston Co., Ltd., and Fitzgerald, A. S. Oct. 23, 1923. Protective arrangements. - Relates to means for controlling an alternating-current protective circuit comprising an inductive reactance in the circuit with electromagnetic means controlled by a switch operated by the circuit-breaker in the protected circuit for varying the value of this reactance. The reactance is so selected that its value lies on the rising portion of the reactance exciting current curve for the maximum applied voltage and is therefore variable through a range of approximately 1 to 250. The reactance comprises a core or cores 1 as shown in Figs. 1-3 carrying a reactance winding 2 and a con. trol winding or windings 3. These windings are arranged in non-inductive relation, the winding 3 which is supplied by direct current, merely serving to saturate or partially saturate the core and thus vary the reactance of the windings 2 between predetermined limits, the winding 2 thus controlling the alternating current in the protective circuit in which it is connected. In the parallel-feeder protective system, shown in Fig. 4, the windings 2 are connected in parallel with feeder current transformers 8 in a circulat. ing-current system 7. Under normal conditions when the circuit-breaker 6 is closed and the feeder 5 carrying current the control winding 3 is unenergized, current from the direct current source 12 merely lighting a coloured indicator lamp 13. The high impedance of the coil 2 now diverts practically the whole of the circulating current through the transformer 8 of the various feeders. If, however, a fault occurs in a feeder for example, the feeder 5 shown, the excess or spill-over current produced in the transformer 8 causes the energization of relay 9 which completes the circuit of the trip coil 10 so that the circuit-breaker 6 is automatically opened. In opening, the arm of the auxiliary switch 11 is moved from contact 15 to contact 16 so campleting the circuit of lamp 14 and of the control winding 3. The energization of this winding now reduces the reactance of the coil 2 to such a value that the circulating current from the other feeder transformers passes through this winding avoiding the transformer 8, so that the protective gear of the other feeders remains undisturbed. The action of the reactance 2 together with its control winding. 3 is thus equivalent to a switching action short-circuiting the transformer 8. and in a further embodiment described a number of short-circuiting switches in a poly. phase protective arrangement are replaced by reactances of the type described, which may be termed " phantom switches."

Abstract: 943,588. Photoflash apparatus. A. FISCHER. July 10, 1962 [July 20, 1961; July 21, 1961], No. 26549/62. Heading G2L. [Also in Division F4] Photoflash apparatus provided with a fan-like collapsible reflector of which the individual blades 10 are so mounted in a carrier 9 retractable along the reflector axis that, as the carrier 9 is retracted, the blades 10 collapse towards the axis and are retracted into the housing 1 of the apparatus. The housing 1 also contains a dry battery 5, a capacitor 52 and a lampholder 7 through which extends a spent bulb ejector 48. The carrier 9 comprising two annular angle-members 9a, 9b receives the bent ends 12 of the blades 10, which are surrounded by a spring 14 tending to force the blades to the extended position. The reflector is moved to the open position and retracted by means of finger grips 22, 23 which are attached to pins 24, 25 extending from the carrier 9 through slots 26, 27 in the housing 1. If the carrier is moved until pins 24, 25 reach the forward ends of their respective slots, the reflector is fully expanded and suitable for use with a lens of normal focal length. To use the reflector with a lens of longer focal length, the carrier is held in an intermediate position by rotating it until pins 24, 25 enter recesses 29, Fig. 1. A closure 34 for the housing carries a contact spring 41 and has an annular recess 40 in which a connecting lead 42 carrying a contact 43 is stored when not in use, the contact 43 then being received in a foot 56, which can be used to attach the housing to a camera. A disc 49 indicating stop valves to be set for flash exposures is pivoted on the closure 34. Blades 10 may be made of spring steel.

Title: Improvements relating to railway signalling systems
IPC: B61L1/18
Filed: 1926-10-25
Abstract: 284,386. Westinghouse Brake & Saxby Signal Co., Ltd., (Union Switch & Signal Co.). Oct. 25, 1926. Electrical systems, automatic.-In a system of the kind in which interrupted current is supplied to the track, a relay is provided controlled by a thermosensitive element. The thermosensitive element may effect control of a coding relay which itself controls the supply of interrupted current. As shown, the rails 1, 1<a> of an insulated track section are normally continuously supplied with current from a transformer T the secondary 4 of which is bridged across one end of the track through a back contact 13 of a normally deenergized coding relay C. The other end of the section is bridged by the primary of a transformer A the secondary circuit of which includes the heating coil 7 of a thermosensitive relay B. The thermosensitive element 8 of relay B is in circuit with a track relay R normally energized from a local battery 9. When the track section is occupied, coil 7 is de-energized and element 8 cools, with consequent de-energization of relay R, the back contact 10 of which then closes the circuit of coding relay C, which circuit includes a local battery 11 and back contact 12 of relay C. Relay C is thus intermittently energized as long as the section is occupied, and the corresponding operation of contact 13 causes an interrupted supply of current to the track which may constitute a code indicative of traffic conditions. When the track becomes unoccupied, the system restores to normal condition.

An instrument for measuring interpupillary distance comprises two objectives for forming images of each pupil, two elements which are simultaneously movable in a direction perpendicular to the light path to displace the rays by a measurable amount and a semi reflecting system for combining the two light paths so that both images may be viewed through an eyepiece. As shown, images of pupils P 1 , P 2  are formed by objectives O 1 , O 2 , O 3  and the two light beams are displaced by moving intermediate lenses A 1 , A 2  together and/or relative to each other by slide means not shown and by pinion R, which meshes with two racks on the lens mounts, until the images which are formed in the field of view of eyepiece O k  are centred at the intersection of the eyepiece cross wires. The position of the patient's pupils relative to each other and to the bridge of his nose which corresponds to the axis of symmetry of the instrument can thus be measured. The patient looks at an image of a mark M. The lenses A 1 , A 2  may be replaced by rotatable mirrors and prisms Pr 1 , Pr 2  by fully and partially reflecting mirrors.
