Title: Improvements in testing arrangements for electric networks
IPC: G01R27/18
Filed: 1928-07-04
Abstract: 293,831. Ateliers de Constructions Electriques de Charleroi. July 13, 1927, [Convention date]. Detecting and locating faults.-An arrangement for testing a network, permitting detection of a feeder having a fault to earth utilizes the current transformers i<1>, i<2>, i<3>, operating the measuring instruments, and the potential transformers t<1>, t<2>, t<3>, which normally serve as choking-coils for the discharge to earth of static charges. In series with the secondary windings of the potential transformers t<1>, t<2>, t<3> are relays r<1>, r<2>, r<3> which operate on the occurrence of a fault to earth on the corresponding line and close the circuit of a bell s. A voltmeter may be arranged in shunt with each of the relays r<1>; r<2>, r<3>. In order to determine which line is faulty, a transformer T is arranged with its primary winding in the earth connection of the transformers t<1>, t<2>, t<3> and its secondary winding connected to the pressure winding of a relay R of wattmeter type. A switch S, operable from a distance, normally short-circuits the transformer T. A three-pole detecting switch c is arranged in the secondary circuit of each of the instrument transformers and is so arranged that the secondary windings can be connected in parallel to the current winding of the relay R without interruption of the current. When a fault is signalled by the ringing of the bell s, the switch S is opened and the detecting switches c closed singly in succession. Operation of the relay R denotes the presence of a fault on the corresponding feeder. The invention is also applicable to circuits other than three-phase. The Specification as open to inspection under Sect. 91 (3) (a) states also that the relay R operates a siren or other warning device. This subject-matter does not appear in the Specification as accepted.

Title: A control device for a respiratory apparatus
IPC: A61M16/20
Filed: 1964-05-11
Abstract: 1,053,704. Artificial respiration apparatus. O. H. DRAGER, [trading as DRAGERWERK HEINR. & BERNH, DRAGER], May 11, 1964, No. 19587/64. Heading A5T. [Also in Division F2] A control valve for artificial respiration apparatus which operates in response to the patient's attempts to breathe comprises a valve housing 1 with a first port 16 connected to the patient, second and third ports 13, 14 connected to sources of positive and negative pressure, respectively, and a fourth port 12 connected to atmosphere, the valve member being piased into a position in which it closes the second and third ports and opens the fourth port and being movable into positions for permitting inhalation and exhalation in which it closes two of the second, third and fourth ports. The bias is provided by an iron core 8 in the valve member which is attracted by a permanent magnet 9 in the housing or by springs (not shown). When the valve member is in the position determined by the bias, a space 2a in the housing communicates with atmosphere through a vent 30 and a slot 10 in the valve member which is hollow and a port 12, and a space 15 communicating with the patient through the port 16 is closed. When the patient attempts to inhale, the reduction in pressure in the space 15 pivots the valve member about its pivot 5 in one direction to the inhalation position in which the slot 10 registers with the positive pressure port 13 so that gas passes to the patient through slots 10, 11 in the valve member and the space 15, and to the space 2a. On exhalation, the rise in pressure in the space 15 causes the valve member to pivot in the opposite direction into the exhalation position, so that communication via slots 10, 11 is established between the negative pressure port 14 and the spaces 15, 2a. Alternatively, the valve member is a spool valve (Fig. 5, not shown) which is reciprocated between the inhalation and exhalation positions by two electromagnets which are energised in response to the patient's attempts to inhale and exhale respectively, the valve being biassed by a spring.
