Title: Improvements in high tension electric distributing and switching apparatus
IPC: H02G5/00
Filed: 1928-11-01
Abstract: 305,526. Condit Electrical Manufacturing Corporation, (Assignees of Burnham, G. A.). Feb. 6, 1928, [Convention date]. Conduits and casings. -In metal-clad switchgear structures in which high-tension conductors such as the machine busbars are placed above or beside oil switches in order to prevent heated oil and flame which mav be expelled from the oil switches when breaking abnormal currents from reaching and setting up arcing at the high-tension conductors, these conductors are surrounded in their casings by a body of solid non-combustible insulating particles such as sand, the voids between the particles being filled with an insulating liquid. As shown in Fig. 1, a vertically removable oil switch 10 is supported on a frame 12 operated through mechanism including a lead screw 14. The fixed portion of the framework also supports superimposed casings for the feeder 38 and the bus-bars 22, 24, 26 and also casings containing the connectors 30. The whole of these casings are filled with a body 52 of solid insulating particles such as a quartz sand, the spaces between the particles 54 being filled with an insulating liquid, e.g. oil, as shown in Fig. 4. Isolating contacts extend from the cover of the oil switch and oil pots 46 are arranged around these contacts so that when they are in engagement with corresponding isolating contacts depending from the fixed casings the whole of the exposed portions of these contacts are effectively shielded. The packing around the conductors in the fixed casings is such that even if the casings themselves, are not oil-tight the oil is retained between the solid particles so preserving the insulation of the high-tension conductors. Any hot gases or flame ejected from the oil switch casing would normally be prevented from reaching the high-tension conductors and even if a flash-over between the conductors and casings takes place the small volume of oil between the sand particles prevent excessive gas pressure being generated, the sand particles cooling the flame. The presence of the oil, moreover, prevents corona discharge being set up between the sand particles. The insulating body being mobile, can conform to any variations in size or shape of the insulating space.

Title: Improvements in or relating to a process for the manufacture of high anti-knock motorfuel
IPC: C07C2/62
Filed: 1939-12-08
Abstract: 545,183. Acyclic hydrocarbons. TEXACO DEVELOPMENT CORPORATION. Dec. 8, 1939, No. 31845. Convention date, Dec. 30, 1938. [Class 2 (iii)] A cracked naphtha is stabilized by removing a normally gaseous fraction comprising the hydrocarbons containing less than five carbon atoms in the molecule, namely isobutane, n-butane and olefines which are then subjected to an alkylation treatment in the presence of excess of isobutane and an alkylation catalyst such as sulphuric acid. 'The products are separated into a normally liquid hydrocarbon of gasoline boiling range, isobutane which is used in the alkylation process and n-butane which is added to the stabilized cracked naphtha to impart volatility thereto. In the Figure, the cracked naphtha, after passing the stabilizer 2, condenser 7 and accumulator 10 enters the reactor 20 together with recycled isobutane, from pipe 25 and sulphuric acid from pipe 34. The products are separated in a settler 31 and the hydrocarbons passed to a fractionator 48 after being neutralized. For the production of motor fuel, the fractionator 48 is operated so that most of the normal butane is present in the liquid hydrocarbons which are withdrawn through pipe 68 and again fractionated in a fractionator 70 and finally mixed with the stabilized naphtha. Iso-butane which is withdrawn from the top of the fractionator 48 is recycled after passing through another fractionator 56 which separates any remaining normal butane. For the production of aviation fuel, only sufficient butane is retained in the liquid products removed from the bottom of fractionator 48 to meet the volatility requirements of such fuel, most of the butane being recovered from the bottom of fractionator 56 and combined with the stabilized cracked naphtha. Normal gases such as propane are removed from the system through pipe 51.

Abstract: 655,964. Endless conveyers. WINDEN, J. B. VAN DER, and STORK & CO.'S APPARATENFABRIEK N.V. GEB. Dec. 9, 1948, No. 31891. [Class 78 (i)] [Also in Group VI] In apparatus for treating separate like articles in a continuous process an endless flexible conveyer indicated at 1 carries the articles, e.g. bottles, in succession through a liquid chamber 10, a gas chamber 11 and a second liquid chamber 12, and this conveyer has freely hanging U-shaped loops having two adjacent limbs in the gas chamber 11 and the remainder of the limbs in liquid chambers; and in order that the U-shaped loops shall have straight, vertical limbs and be of circular shape at the bottom the conveyer is arranged to restrict the minimum radius of curvature on bending to the required radius. This is carried out by forming the article holders 22, Fig. 2, with enlarged portions 24 which abut against one another when the radius of curvature of the conveyer is reduced to the required minimum. The holders 22 shown are for bottles 23. The holders are formed so that the bottles themselves do not abut each other. The bottles are prevented from sliding out of the holders by the walls of the chambers.

Title: Improvements in or relating to electrical oscillation generators
IPC: H03B5/34
Filed: 1935-11-20
Abstract: 466,032. Valve generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and PARKIN, T. D. Nov. 20, 1935, No. 32119. [Class 40 (v)] [Also in Group XXXVI] The variable tuning-reactance of a valve oscillator is arranged to connect in circuit a resonant device, e.g. a piezo-electric crystal, during a portion of its rotation, and to disconnect it during another portion of its rotation, the first portion being under the control of a one-way drive so that the frequency of the tuned circuit can only approach that of the crystal in a predetermined direction. In a second arrangement, the shaft of the tuning reactance switches a back-coupling coil into circuit in order to start oscillations as the tuning approaches that of the crystal, the coil being disconnected when the tuning is correctly adjusted. Fig. 3 shows the first arrangement, comprising a back-coupled oscillator with a crystal 4 connected between the anode and grid of the valve 1, and with a tuning condenser 3 of the series type adjustable by rotating a shaft 3S. A wheel 5 on the shaft has ratchet teeth along half its rim engaging with a fixed pawl. A drum 7 on the shaft carries conductive strips 8, 9 which during the one-way section of the shaft's rotation connect the crystal 4 in circuit. During the other half of the shaft's rotation (which may be effected in either direction) the crystal 4 is disconnected and shorted by the strip 10. With the crystal connected between anode and grid as shown, the permissible direction of rotation is such as results in a decreasing frequency of the tuned circuit ; but when the crystal is between grid and cathode, the permissible movement is in the opposite direction. In the second arrangement, Fig. 6, no permanent back coupling is provided, and the circuit will not oscillate without the crystal. To overcome difficulties in starting selfoscillation, the drum 7 on the condenser shaft 3S is provided with another contact 17, the contact brush 24 of which, as the tuning approaches the crystal frequency, connects a back-coupling coil 25 between the grid and cathode, and sets up oscillation. Further movement of the tuning-shaft removes the back coupling but leaves the circuit oscillating under the control of the crystal. During the. reversible half of the shaft's rotation the crystal is disconnected and shorted as the brushes 20 ... 23 pass on to the strip 18, and the back-coupling coil is connected by the strip 19, the valve then functioning as an ordinary reaction oscillator.
