Title: Process for the production of lubricating oils
IPC: C10G50/00
Filed: 1936-12-19
Abstract: In the process for the production of lubricating-oils by condensation of products obtained by cracking selected fractions produced in the catalytic hydrogenation of carbon monoxide as described in the parent Specification, the condensation catalyst which has become spent after use in a series of condensation reactions at increasing temperatures is regenerated by the addition of small quantities of fresh catalyst and, while commencing at the low conversion temperatures originally employed is used again for carrying out a series of similar condensations in which the reaction temperature is raised from condensation to condensation.  Alternatively the spent catalyst can be further utilized by employing it in the conversion of cracked products of different composition and of increasing olefine content. When using a cracked benzine containing 53 per cent unsaturated hydrocarbons for the condensation reactions, 1000 gm. of this benzine is first converted at 20 DEG  C. for 21 hours with 50 gm. of fresh aluminium chloride.  The lower aluminium chloride contact layer is separated from the upper benzine-lubricating oil layer and used for the conversion of a further 1000 gm. of the benzine at 55 DEG  C. for 24 hours the process being repeated with further 1000 gms. quantities of benzine at 90, 120, and 140 DEG  C. respectively.  After the fifth conversion 10 gm. of fresh aluminium chloride is added to the contact layer which is then used in the same way for the conversion of further 1000 gm. quantities of benzine commencing again at the original low conversion temperature of 20 DEG  C. and increasing the temperatures to 40, 55, 90, and 120 DEG  C. for the succeeding condensations.  The process can then be repeated by adding a further 10 gms. of fresh aluminium chloride.

Abstract: 1,245,103. Tufting-machines. MERCHANT INVENTORS Ltd. and L. M. BALLAMY. 18 June, 1969 [29 July, 1968], No. 36000/68. Heading D1G. In a tufting machine a looper 27 and cutter 17 are interconnected in such a manner that oscillatory cutting motion of the cutter imparts corresponding oscillatory looping motion of the looper. As shown in fig. 1 the cutter has two arms 15, 16 fixedly mounted on a tubular sleeve 14 which is rotatably mounted on a shaft 12. A block 21 is held in a yoke on the driving arm 16 and engages a rotary eccentric on a shaft in the bed of the machine, rotation of the eccentric thus producing a cutting motion of the cutter 17 and cutting blade 18. The looper 27 is mounted by a screw 28 to a shaft 25 mounted on a sleeve 24 on a looper axle 22. A pin 34 extends through a flanged block 35 slidingly mounted in a rectangular aperture 19 in the cutter arm and passes through a slot in the looper blade to engage the looper shaft 25. Thus when the cutter arm is moved the block 35 is caused to move the looper 17. A wiping contact to produce a cutting effect between the looper and cutter is ensured by a spring 36 and the looper is adjustable against the action of a compression spring on the axle 22 to set its position relative to the needle. The work is fed by rotating wheels which engage the upper surface thereof and are driven by an oscillating bar 74 through a free wheel device 75 and bands 92 in synchronism with the needle operation of the machine such that the work is stationary when the needle penetrates therethrough. The bar 74 is oscillated from a crank 72 on the main upper needle bar drive shaft and an adjusting bar 83 is connected to the bar 74 by a sleeve 85 and this varies the feeding movement of the wheels. The freewheel 75 comprises a cam and roller arrangement which only drives in one direction of oscillation of the bar 74. The feeding wheels have toothed edges to engage the work. A throat plate 54 is provided which may be positionally adjusted by means of a thumb nut 57.

[Class 102 (i).] In a compressed air-accumulator, the supply and discharge of liquid are regulated by electrical means dependent on change of level in such a manner that the control means comes into operation by interruption of the current. The accumulator 1 is supplied by a pump 3 through valve 5, pipe 4, and valve 7. A pump return flow valve 10 is controlled by an electromagnet 9 and the valve 7 is controlled by an electromagnet 8. Both electromagnets are controlled by a contact device 11 subject to changes of water level in the accumulator 1. When the water level is low, the circuit of electromagnet 8 is broken at 11 and the valve 7 closes so that water cannot be wthdrawn. When the water level is higher, the valve 7 opens to allow water to be withdrawn, and when the level reaches a desired maximum, the circuit of the electromagnet 9 is broken and the valve 10 opens so that water is not delivered to the accumulator. In the event of a breakage in the electric circuits the valves move to the safety positions. Fluid pressure may be controlled in a similar manner.
