Patent GB-947555-A (GB)
Title: A process for carrying out liquid phase oxidations of cycloparaffins
Filed: 1962-06-04
Abstract: Cycloparaffins are oxidised to the corresponding alcohols, ketones and acids by contacting them with oxygen and a conventional catalyst at elevated temperature and pressure in a first stage so that the conversion of oxygen is limited to 25-75% and then continuing the oxidation without the addition of further reactants in at least one further stage.  Suitable catalysts are, for example, salts of polyvalent metals which are soluble in hydrocarbons, such as cobalt and manganese naphthenate.  The conversion of oxygen may be limited in the first stage by adjusting the temperature or residence time or both. In the examples cyclohexane is oxidised to cyclohexanol and cyclohexanone.

Abstract: 724,160. Walls; ventilation; building- blocks; temporary wall shuttering. BAGGULEY, W. W. Dec. 1, 1953 [Sept. 2, 1952], No. 22013/52. Classes 20 (2), 20 (4), 87 (1) and 137. A wall is constructed from inner and outer courses formed from concrete or like blocks A, Fig. 8, or cast in situ with a space G between them to form a cavity in the wall and the upper faces of each course are formed with spaced recesses to receive tiles H which extend across the cavity and are formed with grooves J in their upper surfaces disposed centrally of the cavity and parallel with the faces of the wall. Each block A, Fig. 1, has a flat face to form the inner or outer surface of the wall, the opposite face being recessed at B to lighten the block. The upper side C has two recesses D, the bases of which are formed with grooves E. After bonding the blocks together as in normal brickwork, waterproof tiles H, Fig. 5, are placed in the recesses D, the ribs L engaging the grooves E and holes M in the tiles acting as a key. The tiles in one course are over the spaces between the tiles in the adjacent courses. The groove J may be formed by moulding the tile to a V-shape in the centre, the ends of the groove having guide channels K. Where a dividing wall joins an outer wall, the blocks forming the inner face of the latter are shaped so as to form a vertical channel which receives the end of the dividing wall. The foundation for the wall has ventilating grids U therein on the inner face to allow warm air to pass up the cavity G and escape from the top thereof or through ventilating grids provided in the top of the outer face. For moulding a wall in situ, each course is formed between shuttering consisting of two side rails 0, 0<SP>1</SP>, Fig. 9, and a core P, the latter being in sections for easy removal. Each section of the core is secured by studs Q<SP>1</SP> to arms Q, the section being in two parts which are separable along the line Q<SP>3</SP>. The recesses to receive the tiles are formed by parts Q<SP>4</SP> on each section of the core P. In a modification, the core P tapers from the top downwards.

Title: Tractor-Implement Draft Control Device.
IPC: A01B63/00
Filed: 1968-05-09
Abstract: 1,186,999. Draught control device. DEERE & CO. 9 May, 1968 [10 May, 1967], No. 22039/68. Heading A1P. Draught of a tractor implement is controlled by a device mounted on the tractor body, the device being adjustable to control light and heavy draught. The implement draught links 14 are connected in an A- frame 12 attached to the tractor body 10, the A-frame being supported by a bar 24 supported at its ends on the tractor body so that rearwardly exerted draught forces cause the outer ends of bar 24 to deflect rearwardly resulting in bowing of its midportion. A hydraulic circuit including a valve 33 and and a piston cylinder 31, 30 controls a rockshaft 16 which is connected to the draught links 14 of the implement 22. A lever 28 extends between the rockshaft 16 and the responder bar 24, the lever being pivoted about a fulcrum 39 on supports (of which only one, 26, is shown) on the tractor body 10. A cam 40 on rockshaft 16 co-operates with a cam follower 41 on lever 28, the cam follower 41 being connected through a servo-mechanism 37 to the valve 33. The responder bar 24 is mounted adjacent the lower end of lever 28, the bowing of the bar 24, due to increase in draught forces, causing the bar to engage a stop 43 on lever 28 to rotate the lever about fulcrum 39 and thus to shift valve 33 to the right to control the rockshaft 16. The fulcrum includes a composite rockshaft (46), (47,) (48), Fig. 6 (not shown), also having an eccentric portion (50) to which lever 28 is journalled so that the lever is adjustable, about its upper pivot point 42, to two positions, Figs. 4 and 5 (not shown), by a lever device 57, 55, 54 connected to an arm 52 on a rigid part 51 interconnecting the eccentric (50) and rockshaft part (48). Another arm (53) of the interconnecting part 51 is connected to a plunger (61) slidable in support (27) on the tractor body, the plunger co-operating with a pin (60) on the lower end of lever 28. The plunger (61) therefore moves in accordance with the two positions of lever 28, Figs. 4 and 5 (not shown). For light draught control the lever is in the position as seen in Fig. 4, so that the bar 24 is in contact with the stop 43 on lever 28. For heavy draught control the lever is separated by a gap from the stop (43), Fig. 5 (not shown). In this way the total draught load range is divided into upper and lower portions. For light draught control, the response of the lever to bowing of the bar is limited to the lower part of the range until bar 24 is stopped by plunger (61). For heavy draught control, during the lower part of the range, until bar 24 engages stop 43, there is no effect, there being response only in the upper part of the range.

Title: Manufacture of benzenecarboxylic acid fluorides containing trifluoromethyl groups
IPC: C07C51/60
Filed: 1936-08-12
Abstract: Benzene carboxylic acid fluorides containing trifluoromethyl groups are made by reacting technically anhydrous hydrogen fluoride or antimony trifluoride at a raised temperature with a benzene carboxylic acid chloride substituted by one or more trichloromethyl groups and which may contain further substituents. The products are intermediates for dyes and pharmaceutical products.  In examples, technically anhydrous hydrogen fluoride is reacted under pressure with (1) p-trichloromethylbenzoyl chloride or its nuclear substitution products such as its mono- or poly-bromoderivatives or poly-chlor derivatives or 1-trichlormethyl - 2 - chlor - 4 - benzoyl chloride, or (2) o-trichlormethylbenzoyl chloride.  Also in examples (3) antimony trifluoride is reacted with m-trichlormethyl-benzoyl chloride or its nuclear substitution products such as the mono- and poly-chloro- or bromo-derivatives; (4) hydrogen fluoride or antimony trifluoride is reacted with 3.5-bis-trichloromethylbenzoyl chloride or halogen substitution products thereof; (5) hydrogen fluoride or antimony trifluoride is reacted with 5-trichloromethyl-1.3-benzene dicarboxylic acid fluoride or its nuclear substitution products such as the mono- and poly-halogen derivatives or with 4-trichloromethyl-1.2-benzene dicarboxylic acid chloride. Trichlormethylbenzene carboxylic acid chlorides are made by chlorinating the corresponding methylbenzene carboxylic acid chlorides or by partially saponifying polytrichlormethylbenzenes. p-Trichlormethylbenzoyl chloride is obtained from p-di-(trichlormethyl)-benzene by heating with water in presence of ferric chloride.  m-Trichlormethylbenzoyl chloride is made by chlorinating m-toluic acid chloride in presence of phosphorus trichloride.

Abstract: 1306287 Ratchet mechanism E HEISSTHUROW 8 May 1970 [15 May 1969] 22384/70 Headung F2Q [Also in Divisions B3 and F1] In an indexing apparatus (see Division B3), a driving ring 6 moves to-and-fro through a predetermined angle beneath an indexing ring 35, unidirectional angular movement being imparted to the ring 35 by a pawl 39 carried by the ring 6 and urged into engagement with teeth 36 on the indexing ring 35. When the driving ring 6 reaches the end of its movement to the left, a fixed pin 42 abuts the pawl 39 and adds to the force of a spring 38 in urging the pawl into more positive engagement with the teeth 36. Simultaneously a cam surface on the ring 6 allows a spring 44 to move a locking pin 43 into one of the spaces 37 between the teeth 36, thereby to lock the indexing ring to a fixed housing 1. On movement of the ring 6 in the reverse direction the cam surface on the ring 6 co-operates with a complementary surface on the pin 43 to retract the latter. A pin 40 loaded by a spring 41 has a head with an inclined surface which co-operates with the teeth 36 to assist the pawl in preventing the ring 35 overshooting at the end of an indexing movement.

Abstract: 903,055. Fluid bearings. COMMISSARIAT A L'ENERGIE ATOMIQUE. June 27, 1960 [July 7, 1959], No. 22458/60. Class 12 (1). A fluid bearing assembly comprises a preferably fixed bearing 2, and a rotatable shaft 1, the bearing having grooves 3a, 3b, at each end to oppose the flow of fluid. The shaft is supported in the bearing by the fluid, the pressure of which is maximum at plane OA, and minimum at plane OB, and the pressure is maintained at the ends of the bearing by forming the grooves with circular arcs a, b, preferably axially staggered. Fluid passing into the low-pressure region is circulated by the shaft and moves along to the ends of the bearing and leaks out of the latter, but due to the shape of the grooves, this leak-off is retarded, thus increasing the fluid pressure at the ends.
