Title: Improvement in or relating to the tool carriers of lathes
IPC: B23Q1/68
Filed: 1940-08-28
Abstract: 545,627. Lathes. JONES & LAMSON MACHI NE CO. Aug. 28, 1940, No. 13584. Convention date, Sept. 8, 1939. [Class 83 (iii)] In a lathe having a tool carrier which is rockable to and from the work by a link, the point of connection of the link with the carrier is adjustable in position, so that, when desired, a greater pivotal movement may be imparted to the carrier to facilitate insertion and removal of the work. As applied to a lathe as described in U.S.A. Specification 1,865,527 in which the top tool carrier 30 is rocked about the bar 4 by a link 40 connected to the back tool carrier 15 movable about the bar 3 by a cam 17, the link 40 instead of being pivoted at a fixed point on the carrier 30, is connected to a slide 43 carried by the piston rod 44 of a fluid pressure cylinder 46 fixed to the carrier. When the parts are in cutting position as shown in Fig. 5, the link is substantially at right angles to the slide 43. When the carrier 15 is retracted from the work, the carrier 30 is also retracted to some extent, but if it is desired to remove the work 25, e.g. an aircraft engine cylinder, pressure fluid is admitted to the cylinder 46 to move the pivotal connection of the link 40 nearer to the axis of the bar 4 so that the carrier 30 is further retracted to the position shown in Fig. 4.

Abstract: 1391067 Catalyst components for olefin polymerization SOLVAY & CIE 23 March 1972 [23 March 1971 17 Aug 1971 8 Oct 1971] 13660/72 Heading C3P A solid particulate catalytic complex for the stereospecific polymerization of α-olefins having 2 to 18 carbon atoms comprises a major proportion of TiCl 3  and is in the form of generally spherical particles constituted by agglomerates. of microparticles having a cellular structure such that the total specific surface area of the complex is greater than 75 m.<SP>2</SP>/gm. and the total pore volume of said spheroidal particles is greater than 0À15 cc./gm. Preferably the apparent density of the complex exceeds 0À6 kg./dm<SP>3</SP> and the diameter of the agglomerates is between 5 and 100 microns. The complex may have the formula T 1 Cl 3 (AlR n X 3-n ) x C y  where R is a C 1 -C 18  hydrocarbon radical, X is halogen, n is 0 to 2, x is less than 0À30, y is greater than 0À001 and C is a complexing agent capable of forming a complex with the titanium halide and the aluminium halide or organohalide. The complexing agent may be an ether, thioether or thiol. The complex is used in conjunction with an organocompound of a metal of Group I(a), II(a) or III(b) of the Mendeleef Periodic Table to polymerize olefins. In the examples TiCl 4  is reduced with AlEt 2 Cl and heated, treated with diisoamylether, di-n-butyl ether or di-n-butyl sulphide in hexane or isodecane and reacted with TiCl 4  to produce the catalytic complex which is used with AlEt 2 Cl to polymerize propylene, ethylene or n-butene-1 in hexane in the presence of hydrogen, to prepare block copolymers of ethylene and propylene and to continuously or bulk polymerize propylene. In comparative examples TiCl 4  reduced with H 2 , Al or AlEt 2 Cl or the latter reacted with TiCl 4  are used in place of the catalytic complex or the diisoamylether is added to the polymerization medium.

Title: Improvements in and relating to protective equipment for mine hoists and like winding gear
IPC: B66B5/06
Filed: 1943-08-23
Abstract: 571,700. Winding gear control. WORRALL, R. W., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Aug. 23, 1943, No. 13738. [Class 78 (v)] A device for controlling the speed of mine hoists and like winding gear comprises a horizontal disc 1 driven through gearing 5, 6, 8 from the winding drum &c. On the upper face of the disc are carried two tangentially disposed mercury switches 10, the switch tubes being each inclined to the horizontal, in opposite senses, so that excessive acceleration will cause the mercury to rise in the tube and break circuit. The two switches are intended for control one in each direction of wind, and if control of retardation rate is also desired, an additional two switches are mounted on the disc 1, or alternatively, two disc devices are employed. A friction-controlled throw-over switch cuts out one or the other of the switches 10 according to the direction of wind. If application of the control only to the slow speeds at the ends of the wind is desired, a mercury switch 22 is mounted radially on the disc 1, the switch tube being inclined upward so that beyond a predetermined speed the mercury will climb up the tube and break circuit. The switches 10 may also effect this purpose by being arranged between the tangential and radial positions, and means for adjusting them angularly may be provided. The circuit through the switches 10 and 22 is by way of slip rings 12, 13, 14 and brushes 19, 20, 21, and includes a solenoid-operated switch which controls an auxiliary control valve of a braking engine of known type having an operating weight suspended by a fluid-controlled piston.

Abstract: 1428914 Making aluminium paste ECKARTWERKE STANDARD - BRONZEPULVERWERKE CARL ECKART 29 March 1974 [17 Jan 1974] 14072/74 Heading B3A A method of making a water-dispersible aluminium paste comprises grinding aluminium into finely divided particles in a high molecular weight hydrophilic wax dispersed in a waterimmiscible inert organic liquid which serves as a grinding liquid. Aluminium powder of particle size less than 400 Á, white spirit and either polyethylene oxide wax or polypropylene glycol wax are placed in a ball mill and ground for seven hours. After this time the mixture is diluted by the addition of more white spirit, pumped out of the mill and passed through a 90 or 120 Á sieve. The mixture passing through the sieve is pressed in a filter press to leave a part having a residual white spirit content of about 20%. Before use the paste is stirred with water, about 2-3 parts of water to one of paste, and the mixture so produced is vibrated causing the white spirit to rise to the surface so that it can be decanted away. Alternatively the mixture may be centrifuged and the aluminium powder and water removed are preferably stirred to give an intimate mix. The aluminium-water paste is used in the manufacture of aerated cement.

Filed: 1941-11-05
Abstract: 608,213. Lathes. FAIRWEATHER, H. G. C. (National Acme Co.). Nov. 5, 1941, No. 14287. [Class 83 (iii)] Hollow spindle lathes have solenoid operated means for tipping the cam-shaft when nothing remains of a stock bar but a piece too short to produce a further article. The device is made as an attachment for existing machines. The feed stroke of the feed fingers is effected by a spring and when the fingers have pulled off the end of the stock bar on the previous arm operated return stroke the extra movement imparted to the feed tube by the spring, due to the short bar end failing to strike the stop at the normal time, closes a switch energizing a solenoid, the core 29 of which has a connection 28 pivoted to a latch 30, itself pivoted at 31 and engaging the end of a lever 27 engaging a pin 26 on the control rod 20 for the cam-shaft clutch. When the latch is tripped a spring plunger 33 rocks the lever and disengages the clutch. On de-energization of the solenoid, a spring 32 returns the latch and the mechanism is reset by a hand-lever that re-engages the clutch. In a modification the lever 2 is pivoted at its lower end and the latch is at the upper side of the solenoid. The spring plunger is replaced by a tension spring connected to the centre pivot of toggle links, breaking of the toggle effecting the rocking of the lever.

Abstract: 593,609. Discharging coke ovens. SIMONCARVES, Ltd., and PLANT, C. R. June 8, 1945, No. 14595. [Class 51 (ii)] [Also in Group XL] In a coke-discharging machine having a ram machine and a coke guide machine, safety means for preventing an oven being discharged before the coke guide and pusher machines are in alignment and the correct coke side door has been removed, comprises a lamp mounted on the coke guide machine projecting infra red rays across the top of the coke oven on to a light sensitive cell mounted on the ram machine when both are correctly aligned, the cell output being used to enable the ram motor to be started. The switch j, closed only when the flapper plate or retractable racking trough (not shown) is in position before an opened coke chamber, lights the lamp a mounted on the guide machine b. The output of the cell d mounted on the ram machine b', amplified by a valve e, energizes a relay k, provision being made to prevent this occurring accidentally. The relay contact closes the contact of a coil l, actuating a three phase contacter m, so that the ram motor may be started and closes a contact o to maintain the circuit of the coil l. A signal lamp f is illuminated when the machines are aligned and contacts on the relay k switch in a lamp g when the apparatus is ready for operation. Contacts n on the ram machine travel controller break the circuit of the coil l when said controller is moved from the "off" position and contacts r on the ram controller complete the circuit to the coil l when the controller is.in the "off" position or is moved into position for movement of the ram into the oven. A limit switch p breaks the circuit on completion of the ramming process and if any component of the safety device fails, the whole may be switched out of use. A milliameter h may be wired in circuit to record reception of the infra-red rays should the signal lamp f fail.
