Abstract: 908,262. Discharge lamp arrangements; transformers. ADVANCE TRANSFORMER CO. Feb. 11, 1959, No. 4855/59. Classes 38 (2) and 38 (4). A circuit for operating one or more gas discharge lamps L from an A.C. supply of lower voltage than the igniting voltage of the lamp comprises a transformer having an elongate core carrying a primary winding divided into two parts P 1 , P 2 , in series voltage opposition, physically separated along the length of the core, and at least one secondary winding S in additive voltage relation to P 2 and in closer coupled relation with P 2  than P 1 , connected to the lamp through reactance C. The effect of P 1  is to increase the voltage across P 2  above that of the supply, which primary P 1  may be used partly as a ballast by connecting the lamp to the right-hand end of this winding (Fig. 7, not shown). A number of other circuit arrangements are described having two or more secondary windings for a pair of lamps, and with additional windings for heated cathode lamps. The transformer (Fig. 1) which may be of clamped or forced fit construction, has an air space 62 between P 1  and the remainder of the windings, and one or more slots 51-53 which may be of unequal size forming bridged air gaps beneath the secondary winding to equalize flux distribution. Magnetic shunts may also be formed between the windings. Constructional data for the transformer is given in the Specification. Specification 722,315 is referred to.

Patent GB-601906-A (GB)
Title: Telecommunication systems
IPC: C11D13/02
Filed: 1945-03-02
Abstract: 601,906. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. March 2, 1945, No. 5241. Convention date, April 21, 1944. [Class 40 (iv)] In an automatic exchange system a subscriber is provided with a number of keys which, when depressed cause representative resistances t( be connected successively in the subscriber's loop. At the exchange the register comprises pairs of gas discharge tubes which respond to particular potentials characteristic of the selected loop resistances and control selector switches in accor dance therewith. A series resistance is inserted in each loop at the sub station to compensate for differ ences in line resistances. The key sender is described fully in Specification 601,947 and comprises ten numbered keys. When any of these is depressed the local ringer and transmitter are short-circuited and two or three of five contacts, depending on the key depressed, are operated in turn to cut corresponding resistances into the subscriber's loop. When a calling line is extended to the register, relay RAR releases, followed by slow-release relay LDR, thus momentarily earthing the line to discharge it, and connecting line a to point E1. Relay RBR then operates HTR to connect the point E1 to 48-volt battery and to connect high tension to the valve circuits. Dialling tone is connected over tone transformer TT. The incoming series of potentials is now applied to the gas-discharge tubes, the appropriate combination of which fires, as described in Specification 628,174 and operates corresponding relays GVR1 ... GVR5. GVR5 is operated last for all keys and connects earth to the operated relay contacts and thence to digit storage relays XR. In addition, GVR5 releases HTR to cut-off the tubes and removes earth from the operated XR relays, which thereupon lock up in series with transfer relay TR1. This transfers the tube circuits to the second set of XR relays for the second digit. The process is repeated similarly for all remaining digits. Specification 624,557 also is referred to.

Title: Improvements in target throwing traps
IPC: F41J9/20
Filed: 1928-02-20
Abstract: 315,894. Marks, E. C. R., (Chamberlin Cartridge & Target Co.). Feb. 20, 1928. Projecting disc targets.-The targets are projected into the air bv a throwing-arm the actuating means for which serves also to cushion the arm in its outward travel and to return it to latched position again. The arm 3 is fixed to a spindle 12 supported in a rectangular frame pivotally supported at 6 and angularly adjustable at 7. The actuating means consists of a spiral spring 17 anchored to a lever 19 and secured by a rod 15 to a crank 14 loose on the spindle 12. A slot in the crank receives a pin 32 depending from another crank arm 33 fast with the throwing arm. Also rigid with these arms is another arm 35 having a pin 36 adapted to be held by a latch 39 mounted for longitudinal movement only and acted upon by springs 43. In the set condition the spring 17 tends to urge the pin 36 upward in Fig. 4 but this is resisted by the latch a pin 44 on which bears against a shoulder on a lever 46 pivoted at one end and supported at the other by the core 48 of a solenoid 49. When the circuit is made therefore the core is retracted and the latch is free to move back to allow the arm to be actuated, the latch being then detained by an auxiliary latch 53. Upon rebound of the arm the pin 36 engages this auxiliary latch to free the main latch which thereupon springs forward to hold the parts set again. In order that the rebound may be sufficient to produce re-latching the lever 19, anchoring the spring 17 and movable in one direction by the operator to impart tension to the spring, is released automatically by the returning movement of the throwing arm. The lever lies above an arm 22 having a lug 23 to move the lever 19 to the right, Fig. 3, when a pedal 30 is depressed. The lever is then held in this set position bv a rod 56 pivoted to the lever and shouldered at the other end to engage the frame member 58. As the throwing parts return, a one-way dog 62 pivoted on the pin 32 and conbound may be sufficient to produce re-latching the rod 56 to unlatch the latter and so permit the lever 19 to move to the left to relieve the tension on the spring. An adjustable stop 65 for the arm 22 enables the residual tension of the spring and therefore the overthrow of the parts to be adjusted. Re-setting of the lever 19 may be performed electrically instead of by a pedal.

Patent GB-757937-A (GB)
Title: Surface active sulphate esters
Inventor: KOSMIN MILTON
IPC: C11D1/29
Filed: 1954-02-24
Abstract: The invention comprises surface-active acid sulphate esters having the general formula RO(C2H4O)nC2H4OSO3H in which R is a mixture of primary branched-chain alkyl groups derived from mixed branched-chain C13 alcohols (hereinafter termed "tridecyl alcohol") which are derived by an oxo synthesis from tri-isobutylene or tetrapropylene, carbon monoxide and hydrogen and n is zero or an integer not exceeding 14, and salts of the acid esters with salt-forming metals, ammonia, mono-, di- and tri-alkylamines having not more than 8 carbon atoms in the molecule and mono-, di- and trialkanolamines.  The esters may be prepared by condensing the tridecyl alcohol with from 1 to 15 mols. of ethylene oxide, suitably by-passing the oxide gas into the alcohol at 120-150 DEG  C. in presence of an alkaline catalyst such as the alkali metal hydroxides or corresponding methylates, and then sulphating the product, e.g. with sulphuric acid, chlorsulphonic acid or SO3 dissolved in liquid SO2. Salts of the esters may be obtained by neutralizing with, for example, sodium, potassium or ammonium hydroxide or carbonate, magnesium or calcium oxide or carbonate, methylamines or ethanolamines.  The compounds are used in detergent compositions (see Group III).  Examples describe sulphate acid esters of the above formula wherein n is 0, 2, 3, 4, 6.5 and 9 and their sodium, ammonium or triethanolamine salts.  Neutralization is generally effected with aqueous base in the presence of ethanol and additional ethanol is then added to precipitate inorganic salts; the resulting solutions may be evaporated down to recover the surface-active salts.ALSO:Detergent compositions comprise surface-active acid-sulphate esters having the general formula RO (C2H4O)n C2H4O SO3H wherein R is a mixture of primary branched-chain alkyl groups derived from mixed branched chain C13 oxo alcohols obtained by the oxo synthesis from tri-isobutylene or tetra propylene, and n is zero or an integer not exceeding 14 or salts of these acid esters with salt-forming metals (including ammonia, alkali metals, calcium and magnesium), mono-, di- and tri-alkylamines having not more than 8 carbon atoms in the molecule and mono-, di and tri-alkanolamines.  The compounds, especially the alkali-metal, ammonium and tri-ethanolamine salts may be used alone in aqueous solution for washing of textiles and in production of dish-washing detergents. The compositions may contain alkali metal salts, e.g. phosphates, sulphates, carbonates or silicates and carbohydrate material. According to an example, a detergent comprises the sodium salt of an ester as defined above in which n = 2, starch, carboxymethyl cellulose and tetrasodium pyrophosphate.  The preparation of the sulphates is described (see Group IV(b)).
