IPC: C10L1/30
Filed: 1944-06-29
Abstract: Motor spirits containing amines as anti-knock agents, and particularly those containing metallic anti-knock agents also, are stabilised by incorporating small quantities of a poly-alkyl phenol in which the para-position is filled by hydrogen or a methyl or an ethyl radical, and, of the two ortho-positions, one may be filled by a primary, secondary or tertiary alkyl while the other may be occupied by a primary or secondary alkyl.  Phenols in which the alkyl radicals, which may be aryl substituted, contain not more than 16 or 20 carbon atoms are to be preferred. Poly-alkyl phenols particularly mentioned are 2 : 4 : 6-trimethyl, 2 : 6-dimethyl, 2 : 4-dimethyl-6-secondary butyl, 2 : 4-dimethyl-6-tertiary amyl, 2 : 4-dimethyl-6-tertiary octyl and 2 : 4-dimethyl-6-tertiary butyl phenols.  Preferably alkylated mono-nuclear amines containing not more than 6 carbon atoms in all alkyl radicals are employed.  In the case of motor spirits containing amines and tetra-alkyl lead 2 : 4-dimethyl-6-tertiary butyl phenol, which stabilises tetra-alkyl lead, is preferably employed together with another of the above phenols.  Proportions of polyalkyl phenol and amine incorporated in the gasoline are .0001-0.1 per cent. by weight and 0.25-3 per cent. by volume, respectively.  Amine solubilisers such as low molecular weight alcohols, ethers and ketones or aromatics such as benzene or toluene may be present.

Title: A cascade circuit for generating high unidirectional voltages
IPC: H02M7/10
Filed: 1962-03-30
Abstract: 999,311. Rectifying. SIEMENS-SCHUCKERTWERKE A.G. March 30, 1962 [March 30, 1961], No. 12460/62. Heading H2F. A cascade circuit for generating high direct voltages from a polyphase supply has a number equal to the number of phases of columns of series connected capacitors (here called shunt columns) arranged to be charged through rectifiers and to feed either directly or through further rectifiers another series capacitor column (here called the series column) so that the capacitors of the shunt column is charged from all the supply phases. In Fig. 1 there is shown a threephase N stage cascade having series columns A, B and C comprising capacitors C s  and a shunt column comprising capacitors C L . Each series column is charged only by its own phase through rectifiers G, and the shunt column is also charged through rectifiers. The stage voltage is 2U#2, where U is the r.m.s. phase voltage. Chokes D<SP>1</SP> compensate for stray capacitance in the way described in Specification 843,736, and do not, in this embodiment, pass direct current. In a modification (Fig. 2, not shown), the rectifiers G are arranged so that the series capacitors C s  are charged from two phases to a voltage U#6. The compensating chokes are connected in star, the star points being connected to the shunt column, so that the chokes pass direct current. The stage voltage is again U#6. The series capacitors of one series column are all charged from the same phases (e.g. column A is charged between phases A and B). In Fig. 3 the connections are interchanged cyclically. The series capacitors may be charged by the phase-to-phase voltages as in Fig. 3 and the shunt capacitors fed through rectifiers as in Fig. 1 (Fig. 4, not shown). The rectifiers connecting the shunt capacitors, except for the top stage, only pass current in steady operation if the intermediate stages are loaded, and they can therefore be of low rating. Different stages of one cascade may be connected differently, and six phase arrangements, with or without interphase transformers, may be used (Figs. 5 to 9, not shown).

The invention is shown applied to a roundabout. The cars 9 are carried by connecting-links 8 between radial arms 4, which carry wheels 6 at their outer ends and are pivoted at their inner ends to a hub 1 which rotates about a hollow vertical shaft 2. A sheave 13 is secured to the hub 1 and serves to drive the apparatus. Flexible connections connect the cars 9 with the arms 15 of the sheave 13 and serve to take the strain of driving the cars from the pivots 5 of the arms 4, while permitting the cars to rise and fall. A canopy 20 is secured to U-shaped supports 21 which fold fan-like about spindles 22 between the cars. In its open position the canopy 20 rests on the inner side of the cars on the arms 4 and is closed by a cable 24 passing from the centre of the apparatus to pulleys 27 on the links 8. The cable 24 passes through eyes 26 in arms 25 mounted on the spindles 22 so as to exert a normal pull on the canopy. In closing, the canopy 20 stretches springe 36 which automatically open the canopy when the cables 24 are released. A motor 33 operates all the cables 24 simultaneously. Lights may be placed within the canopy and the slotted bottom 40 and dashboard 41 permit blasts of air to enter the cars. When the invention is applied to roller-coasters, scenic railways, &c. the canopy mechanism is operated by an endless cable running freely alongside the track and adapted to be checked by suitable braking mechanism to exert a pull on the cables 24 which are connected to the endless cable. Alternatively, the canopies may be operated by one or more motors mounted on the cars themselves.
