Abstract: The invention comprises tertiary alkyl ferrocenes of formula <FORM:0828965/IV (b)/1> wherein R1, R11 and R111 stand for alkyl radicals and n stands for an integer from 1 to 6.  Specified compounds include 1 : 11-di-tertiary-butyl-, di-tertiary-butyl-, tri-tertiary-butyl-, tetra-tertiary-butyl-, tetra-tertiary-amyl-, 1 : 11-di-tertiary-amyl-, and 1 : 11 - di - (1 : 1 : 3 : 3 - tetramethyl-butyl)-ferrocenes. They may be prepared by alkylating ferrocene with tertiary alkyl halides (e.g. tertiary-butyl or tertiary-amyl chloride) in the presence of a catalyst such as aluminium chloride or zinc chloride and, if desired, in an inert solvent such as ethylene dichloride. Alternatively, an alkali metal derivative of a tertiary-alkyl cyclopentadiene may be reacted with an anhydrous iron halide.  A further process comprises reacting the tertiary-alkyl cyclopentadiene derivative with anhydrous ferrous or ferric chloride or bromide in the presence of a strong organic base as acid-binding agent, e.g. piperidine piperidine or diethylamine. Tertiary alkyl cyclopentadienes may be prepared by alkylation of cyclopentadienyl magnesium halide with the corresponding tertiary alkyl halide, e.g. tertiary butyl chloride.  Details of preparation are given as follows: Example (6) tertiary-butyl cyclopentadiene; Example (9) tertiary amyl cyclopentadiene and Example (10) (1 : 1 : 3 : 3-tetramethylbutyl) cyclopentadiene.  The preparation of the following alkali-metal cyclopentadienyls is also described: Example (6) sodium tertiary-butyl cyclopentadienyl; Example (9) sodium tertiary-amyl cyclopentadienyl and Example (10) sodium (1 : 1 : 3 : 3-tetra-methylbutyl) cyclopentadienyl.

Title: Process for reacting organic compounds with a sulphur trioxide
IPC: C07C305/06
Filed: 1963-06-26
Abstract: A process for the sulphonation (including sulphation) of sulphonatable organic compounds comprises reacting sulphur trioxide vapour with the liquid organic compound with agitation in a reaction vessel at a pressure of 1-500 mm. of mercury.  The sulphur trioxide may be used undiluted, or diluted with an inert gas, e.g. air, nitrogen, CO2 or SO2, in a ratio, initially of gas: SO3 of 0.75 to 10 : 1.  Preferred conditions are 75-150 DEG  C. and 1-100 mm. Hg., using pure SO3, or 200-400 mm. Hg. using SO3 in a diluent gas. Suitable sulphonatable organic compounds are higher fatty alcohols, higher fatty acids, alkylaromatic hydrocarbons adducts of higher fatty alcohols or alkylphenols and ethylene oxide.  The SO3 may be introduced into the liquid via a single pipe (Fig. 1, not shown) or via pipes in the agitator blades (Fig. 2, not shown), or, especially when diluted, at high speeds (e.g. 500-1500 ft/sec.) from jets in a manifold, which may thus provide some or all of the necessary agitation (Fig. 3, not shown).  The sulphonated products may be neutralized e.g. with sodium, potassium or ammonium hydroxide, sodium or potassium carbonate, or triethanolamine, and are useful as surface active agents.

Title: Tree harvester
IPC: A01G23/08
Filed: 1973-05-29
Abstract: 1423546 Felling trees L & L LOGGING RESEARCH Ltd 29 May 1973 [5 June 1972] 25492/73 Heading A1E [Also in Division B8] A light-weight mobile tree harvester with tracks 11, 12 capable of travelling over soft ground and snow has shearing jaws 33, gripping arms 34, 35 and delimbing blades 40-42 mounted on a head 28 which is pivoted to a boom 21. The boom is reciprocatable in a cage 22 which can be pivoted by rams 25 about a horizontal pivot 14. The cage is mounted on a platform 16 which pivots in a horizontal plane about a bearing 13. In use the boom is extended and the head 28 is aligned with the base of a tree trunk and hydraulic cylinders 46, 48 operated to cause arms 34, 35 to grip the tree. The jaws 33 are then actuated by hydraulic rams 79 to sever the trunk. Then, while the tree continues to be held, the boom is pivoted upwardly by the rams 25 and retracted. The platform is then pivoted to bring the head out of the path of the vehicle, the boom lowered to a horizontal position, and the head pivoted to a horizontal position, thus bringing the tree to a horizontal position. The shear jaws are then opened, and rollers 37, 38, which are mounted in the gripper arms, are driven by hydraulic motors to shift the tree trunk axially until the cut end abuts a plate 39 on the platform. During this movement the blades 40-42 remove the branches from the first section of the trunk, and this section is then severed by the jaws 33. The delimbing process is then repeated for the subsequent sections.

IPC: H04N3/34
Filed: 1926-10-15
Abstract: 289,104. Television, Ltd., and Baird, J. L. Oct. 15, 1926. Television.-A changing scene is recorded by exploring it in relation to a light-sensitive cell, applying the resulting modulated current to a telephonic receiver, and recording the sounds on a phonographic or like member. As shown diagrammatically in Fig. 1, the scene 10 is explored by devices 11, 12 in relation to a lightsensitive cell 13, the current, amplified at 14, is applied to a loud-speaker 19 associated with a microphone 20, and the current from the microphone is applied to devices 15, 16 operating to record the sounds corresponding to the scene on a phonographic disc 18. The exploring and recording devices are preferably geared together. Speech or other sounds associated with the scene may be. recorded simultaneously on the same disc by devices 22, 23 supplied from the microphone 21 separated from the microphone 20 by a soundproof partition 24. The grooves of the sight and sound records may be parallel grooves of a double spiral, or may be on opposite sides of the disc, or at opposite ends of a cylinder. Preferably one record is formed on the bottom of the groove and the other on the side. Alternatively a single groove may be used for the two records by forming one record on the bottom and the other on the side. The scene is reproduced from the record by utilizing the vibrations of a needle applied to the record track to modulate the current applied to the variable light source in a television reeeiving apparatus. Such modulation may be effected by the use of a microphonic contact or by electromagnetic induction. The exploring device described in Specification 265,640 and the variable light source described in Specification 267,056 [Class 39 (i), Electric lamps, Are &c.] may be used.

Abstract: 224,075. Schilde, P., Bongardt, E., and Rolland, J. Oct. 18, 1923. Mixing, conveying, and distributing concrete and the like. - An apparatus for mixing, conveying, and distributing concrete, mortar, &c. for use in building operations comprises means for feeding the separate materials, in definite proportions, together with a small quantity of water, to a mixer whence they are forced with a rotating motion through a pipe to the point of distribution where the mass is passed through a second mixing device in which additional water is supplied. The apparatus may be mounted on a telescopic mast, and compressed air may be employed for forcing the mass through the pipe and for producing the rotating movement of the mass therein. The materials are fed to hoppers 5, 7, Fig. 1, from which thev are delivered to a mixer 11 where they are mixed with a small quantity of water and forced through the pipe 42 mounted on the telescopic mast 22 and jib 27 to the mixing device 34 where the additional water is supplied. As shown in Fig. 6, the preliminary mixer consists of a fixed drum 63 in which blades 61 are rotated. The mixed materials are forced into the pipe 42 by a worm 66, rotary motion being imparted to the mass by a rotating conical chamber 68 fitted with a helical blade 69; a blast of air, supplied by a pipe 62 on which the worm 66 is mounted, forces the material through the pipe 42. Additional air blasts may be provided at 33, Fig. 1, along the length of the pipe. The final mixer consists of a two-part double conical chamber 52, Fig. 5, enclosing a casing 53. The water is supplied by an annular perforated pipe 55. In a modification of this part of the apparatus, branch pipes are provided for the egress of the compressed air and scraping or mixing blades are provided which are rotated by an enclosed motor. The part 68, Fig. 6, may be provided with separate helical blades, or may be replaced by a stationary drum in which an auxiliary blast of air is introduced laterally through a branch 84, Fig. 12, and is guided by helical blades 85; this device may be also inserted at points along the pipe length to maintain the rotary motion of the mass.
