Abstract: 942,924. Valve and semi-conductor pulse circuits. PYE Ltd. Aug. 26, 1960 [Aug. 26, 1959], No. 29218/59. Heading H3P. In a circuit for converting an A.C. pulse signal into a D.C. pulse, the A.C. pulse is rectified to form a D.C. pulse from which a capacitor C1 is charged through a resistance such as R1  until a trigger device such as a gas tube V4 conducts and remains conductive until the end of the D.C. pulse, when capacitor C1 discharges rapidly via diode V5. The A.C. pulse signal is preferably fed via a cathode follower V1 and full-wave rectified by V2, V2B before being used to cut-off valve V3 (which may be a pentode) and anode voltage of which is used to control the charge on capacitor C1 The positive pulse produced across resistor R3 when V4 fires is differentiated by capacitor C3 and used to trigger a further gas tube V6 which provide a short positive pulse at the cathode before extinguishing itself. The charging time constant may be adjusted by R2 to discriminate against noise or interference pulses. Semi-conductor circuits.-Valves V1, V3, V6 may be replaced by transistors and V4 by a PNPN device. Specification 942,921 is referred to.

Title: Improvements in and relating to electromagnetic switch mechanisms
IPC: G06M1/10
Filed: 1959-08-28
Abstract: 931,984. Automatic exchange switches. HASLER A.G. Aug. 28, 1959 [Aug. 28, 1958], No. 29443/59. Class 40 (4). [Also in Group XIX] A switch is arranged to operate successively individual ones of a plurality of contact sets, in response to successive electrical input pulses. As described, contact-operating springs 16a ... 16k are raised in turn to operate respective associated switch contact sets (Fig. 3, not shown). The first input pulse of a series is applied to an electromagnet 3, a cam 9 on the armature arm 3a of the electromagnet raising a actuating spring 26a thereby to raise the associated contact-operating spring 16a to operate the associated electrical contact set (not shown). During the armature movement, an upturned end of a bent angle-spring 28, the other end of which is fixed in a bent-over end 17a of the contact-operating spring 16a, is rocked to displace laterally the end of the actuating spring 26b associated with an adjacent order. Also during the armature movement, a tooth 21a of an eleven-toothed spring-biased pawl 22 is first moved back by pressure at the edge of a window 18 in the contact-actuating spring 16a, to disengage the tooth 21a from the window 18 in which it normally engages, the pawl then being spring-urged forwards again to maintain the contact-actuating spring 16a in its raised position. The second and subsequent input pulses are supplied (by means not described) to an electromagnet 4 instead of the magnet 3, each of these pulses causing rocking of a ten-toothed comb 10. The second input pulse is effective to raise only the contact-operating spring 16b since the actuating springs 26c-26k are situated adjacent notches in the comb 10. The upward movement of the contact-operating spring 26b is effective to rock the pawl 22 thereby releasing the contactoperating spring 26a which returns to its original position. Also, the actuating spring 26c in the next order is displaced to its operative position. The last or " k " order is adapted when actuated to prepare the first or " a " order via a bent spring 30. The " a " or zero-position order can be operated at any time by supplying a pulse to the magnet 3. In a modification, not described in detail, only one electromagnet is provided, actuation of any contact-operating spring except the last inhibiting operation of the zero order by means of a link so that the zero order is operated in succession to the last or " k " order.

Filed: 1951-12-18
Abstract: <PICT:0703209/III/1> Liquid or gaseous ozone of decreased susceptibility to detonation is prepared from a free-oxygen-containing gas mixture which does not contain more than 20 parts per million, in the case of liquid ozone, or 5 parts per million in the case of gaseous ozone, of volatile oxidizable organic contaminants expressed as carbon dioxide, by weight, calculated on the mixture.  The contaminants may be removed to the above degree or lower by passage of the mixture through liquid oxygen, adsorption on silica gel at low temperatures, but preferably by oxidation as illustrated in Fig. 2.  Oxygen is supplied from cylinder 10 to a combustion furnace 11 containing copper oxide, silver oxide, magnesium dioxide, platinum black or quartz, operating at about 900 DEG C.  The gas containing oxidized contaminants as carbon dioxide then passes to absorbers 12 for the carbon dioxide.  The gas then passes to a cold trap 13 to remove water vapour and thence to ozonizer 14. The resultant ozone may be condensed in condenser 15. The completeness of the contaminant removal can be periodically tested by withdrawing a sample through line 17 and passing it through a combustion furnace 16.  Analysis of the product from line 19 indicates the carbon dioxide concentration.  Similar checks may be made between cylinder 10 and furnace 11 and between cold trap 13 and ozonizer 14.  Materials giving rise to organic contaminants such as synthetic resins and lubricating oils, and certain metals such as brass, copper and magnesium, should be omitted from the system following the furnace 11.
