Patent GB-788181-A (GB)
Title: Improvements in or relating to a process for the production of tetraethyllead
IPC: C07F7/24
Filed: 1955-04-06
Abstract: Tetraethyl lead is prepared by batch ethylation of an alkali metal lead alloy wherein comminuted solid alloy is reacted with liquid ethyl chloride at elevated temperatures and pressures, said temperature and pressure being controlled by suitable boundary cooling, refluxing and venting of the by-product gases until after the ethyl chloride feed is completed and the pressure resulting from the reaction has been substantially reduced, then terminating said byproduct venting; refluxing and boundary cooling and initiating full venting and boundary heating substantially simultaneously with the termination of boundary cooling, thereby reducing the ethylation zone pressure to substantially atmospheric and discharging the ethylated mixture from the ethylation zone.  The venting of non-condensables may be initiated at a pressure of at least 50 p.s.i.g., for example 60-70 p.s.i.g. and is terminated when the ethylation pressure has decreased to the pressure at which said venting was initiated. The procedure is applicable to processes using bed cast alloys as well as to alloys made in the form of flakes.  Detailed examples are given. Specifications 707,074, 707,075 and 718,619 are referred to.

Abstract: 913,212. Electrostatic precipitation. HERBRECHTER, A. L., and MILLAHN, H., [representatives of HERBRECHTER, M.], and JUCHO, G. H. W. March 24, 1959 [March 24, 1958], No. 10086/59. Class 39 (1). The high - voltage electrodes of the platetype collecting stage of a two-stage electrostatic precipitator consist of insulated conductors, e.g. single or multi-strand wires or tapes which are located between the collector electrodes 1 in a zig-zag or meander path in a plane parallel to the collecting electrodes. A single wire 8 may be wound back and forth to form all the high-voltage electrodes of the collecting stage. The wire may be disposed between foils or plates of synthetic material or metal, or may be embedded in a plate of synthetic resin or encapsulated in a casting resin.

Title: Improvements in hydraulically operated copying machines
IPC: B23Q35/18
Filed: 1955-04-06
Abstract: 774,330. Copy-turning. ETABLISSEMENTS A. CAZENEUVE, and BRUET, H. R. April 6, 1955 [April 16, 1954], No. 10106/55. Class 83 (3). In an hydraulic copying- mechanism for a lathe &c., a rockable feeler acts on a slidable control-valve for the tool-slide feed, and means are provided for adjusting the position of the controlvalve without altering the relative setting of the feeler and pattern, or the engagement of the feeler with the valve. The tool-holder 18 is on a slide 1 carrying a block 2, and is adjustable about a pivot 12. A cylinder 5 is bolted to a plate 11 on a support 14 mounted over a transverse slide 15 movable over the saddle 16 of the lathe. A piston 3 secured to the block 2 is slidable in the cylinder 5 and is supplied with liquid through a passage 39, the liquid being exhausted through a passage 36. The control valve 30 controls passage of liquid to the opposite surfaces of the piston. A feeler 21, 23 having a member 24 to engage the pattern 25 is mounted in a rockable spindle 20 in the block 2. Between a bearing surface 27 of the feeler and an extension 47 of the valve 30 is positioned a ball 48 of a vertically-shiftable member 49 comprising an upper ball 50 engaging a sloping surface 53 of a trunnion 54, rotatable by an operating-lever 57. The end of an arm 71 of the operating-lever abuts the end 72 of a vernier. If the lever 57 is swung downwards against a spring 58, the arm 71 moves clear of the vernier. The movement of the block 2 and slide 1 to the left, towards the work, is limited by an adjustable-lever 63 engaging the block. The rocking of the feeler clockwise is limited by an adjustable stop 61. Rocking of the feeler counterclockwise by the pattern moves the valve 30 to the left, whereupon the assembly 1, 2, 18, 21, 23 is moved to the right, and vice versa. If the stop 61 is set so that the block 2 is moved towards the left, depression of the ball 48, by rotating the lever 57 counterclockwise (in plan view), moves the valve 30 to the left to reverse the movement of the block, whereby the production of cuts of different depths can be obtained by setting the position of the lever 57 by the vernier. In another form the feeder is mounted on an eccentric rotated by a verticallyshiftable member slidable by rotating a screw by means of the operating-lever.

[Class 103 (i)] In brakes that are normally applied by hydraulic cylinders, mechanical means by which the brakes may also be applied, for instance in the case of vehicles for parking, comprise balls disposed in conical recesses between a pair of pistons or between parts of a piston whereby axial movement of the pistons is effected by turning one piston or piston part. A brake of the kind comprising a pair of shoes adapted individually to anchor at one end or the other according to the direction of drum rotation is shown. Application being effected by pairs of hydraulic pistons 24, 26 in cylinders 14, 16. The pistons have flanges 27 that transmit the thrusts of the shoe ends to the fixed cylinders. Interposed in conical recesses between each pair of pistons are balls 38. Rotation of one piston 26 of a pair is prevented by engagement of an arm thereon with an aperture in the backing plate. The other pistons have arms 44, 52 that are connected directly and by a link 50 respectively to the ends of the cross-bar 48. Thus application of a pull to the middle point of the bar 48 turns the pistons 24 and moves each pair apart to apply the brakes. Adjusting screws 34 for the shoes are provided. In a modification, each piston 24 of a pair is in two parts and balls are interposed between the parts and the outer part is turned to effect the mechanical application, rotation of the inner part of the piston being presented by a projection thereon engaging a recess in the pistons 26. According to the Specification as open to inspection under Sect. 91, pins or cables may be substituted for the balls. This subject-matter does not appear in the Specification as accepted.

A machine for bending reinforcements for use in concrete comprises a rotatable turntable, a plurality of annular bending dies mounted one within the other concentrically about a central pivot of the turn-table, said bending dies, when in an inoperative position, being located below a working surface of the turn-table, means for axially displacing the bending dies selectively into a raised working position in which the selected die can be engaged by a bar to be bent, and an abutment element and a displaceable gripper adapted, during a bar-bending operation, to guide and to engage the bar with the selected bending die. A selected die, say 3b, of concentric annular dies 3a-3e is raised above the working surface of a turn-table 1, rotated by a motor 8, by a pair of racks 12 on the die engaged by pinions 17 on a shaft 19 rotated by hand or otherwise and locked in position. The dies are formed with collars 9 engaging grooves 10 in the adjacent inner die, so that all the next smaller dies are raised with the selected die. The appropriate die is selected by moving the pinions 16, 17 along the shaft 19 by forks 26, 27 depending from non-rotatable nuts 24, 25 on a threaded shaft 20. In operation, a bar 34 is clamped at one end against a selected die, say 3b, by an elliptical gripper 31 mounted on a polygonal crosssection shaft in a selected hole 30 in the turntable 1. An abutment element 33 mounted in a selected hole 32 in the machine frame prevents the bar 34 from swinging outwards as the bar is bent around the die 3b on rotation of the turn-table 1.
