Title: Process for hydration of olefin to alcohol
Inventor: ODIOSO RAYMOND CAMILLUS
IPC: C07C29/04
Filed: 1962-01-19
Abstract: Olefines are hydrated by passing water which is partially in the liquid phase and the olefine at 250 DEG  to 600 DEG  F. over a sulphide of a metal of Group VI or VIII under pressure conditions so that the sulphide acts as a catalyst, the reactants being passed over the catalyst continuously for a throughput of at least 50 liquid volumes of olefine per unit volume of catalyst.  The pressure may be from 500 to 10,000 p.s.i.g. and the ratio of water to olefine may be from 1 : 1 to 40 : 1.  If desired, a mixture of Group VI and VIII metal sulphides may be used, preferably in an atomic ratio of between 0.1 : 1 and 10 : 1. Various types of olefines are suitable, e.g. propylene, butenes, pentene, heptene, undecene, dodecene, hexadecene, octadecene, nonadecene, aromatics, vinyl benzene, methylene cycloheptane.  In addition to the alcohol, some ketone and ether is obtained together with a hydrocarbon polymer (see Division C5).  The catalyst may be pre-conditioned by continually passing over it olefine and water at 100 DEG  to 250 DEG  F. and 500 to 10,000 p.s.i.g. until 1 to 50 volumes olefine (measured as liquid olefine) per unit volume of catalyst have been passed.ALSO:Hydrocarbon polymers having a boiling-point up to 625 DEG  F. are obtained as by-products of the hydration of propylene over tungsten disulphide catalyst.  The reaction consists in passing water, partially in the liquid phase and propylene at 250 DEG  to 600 DEG  F. over the catalyst at a pressure of from 500 to 10,000 p.s.i.g. for a throughput equivalent to the passage of at least 50 liquid volumes of propylene per unit volume of catalyst.  The ratio of water to olefine may be from 1 : 1 to 40 : 1.

Title: Improvements in sewing machines
IPC: D05B15/00
Filed: 1959-01-20
Abstract: 899,498. Sewing machines. SOC. D'APPLICATIONS GENERALES D'ELECTRICITE ET DE MECANIQUE. Jan. 20, 1959 [Jan. 20, 1958], No. 2096/59. Class 112 In a sewing machine a hooked needle is driven by a lever arm, the pivotal axis of which is displaced by a toggle linkage controlled by the stopping brake, whereby the needle is not threaded during the final stitch-forming cycle, as a result of the range of needle movement being either shortened or shifted. A curved hooked needle 1 is fixed to a carrier 14 pivoted at 15 and connected by a link 13 to a lever arm 11 journalled on a pivot 12 carried by an arm 17 pivoted at 18. A link 44 is pivoted at 19 to arm 17 and at 20 to an arm 21 fixed to a shaft 22. The arrangement is such that arm 21 and link 44 constitute a toggle, the axes 19, 20, 22 of which are normally aligned. When the brake is applied to stop the machine in a predetermined position, shaft 22 turns counterclockwise, whereby the toggle is broken and arm 17 is thereby turned to raise pivot 12, whereby the point of the needle in its last stroke does not descend as far as the threader 4. A pin 16, extending through a bore in pivot 12, limits the movements of the latter. Lever 11 is oscillated via a pitman 10 from a rotary shaft 9. An arm 23, fixed to shaft 22, has a pin-andslot connection 24 with an axially-adjustable link 25 pivoted to one arm 27 of a lever pivoted at 28. The other arm 29 is forked to embrace a pin 30 on a slide 31, normally biased by a spring 33 to engage a stop 32. A plunger 34, mounted in slide 31, is drawn downwardly by the machine-starting treadle. One arm 37 of a bell-crank lever pivoted at 36 carries a follower 38 engaged in a cam groove 39 in a cam wheel 40, whereby a socket 42, carried by the other arm 41, oscillates over the plunger 34. When the treadle is released to stop the machine, plunger 34 rises to enter socket 42, whereby follower 36 moves the cam wheel 40 axially against the bias of a spring 46. A brake lining 49 on wheel 40 is thereby engaged with a gearwheel 47 driven constantly at low speed. Lever 37, 41 is thereby swung to move slide 31 inwardly, whereby pin 30 rocks lever 27, 29 and the toggle broken to raise pivot 12. Follower 38 finally engages a shoulder 48 and thereby wheel 40 is shifted axially out of engagement with wheel 47. Spring 33 moves slide 31 outwardly, and the toggle is re-set to hold pivot 12 in its original position. Specification 810,772 is referred to.

Abstract: 1375754 Oil filters P L FRANCOIS 17 Jan 1972 [3 March 1971] 2161/72 Heading B1D [Also in Division F2] An inward-flow oil filter with an annular filter cartridge 15 has a housing 12 the inside wall of which is shaped to produce a turbulent flow of dirty oil so as to increase deposition of contaminant particles, and to provide pockets to receive such deposits. As shown the housing is formed from two moulded plastics parts with circular grooves 21 and radial cooling fins, Fig. 2 (not shown), which formations also serve to increase the strength of the housing. In a modification, the housing is formed with a helical groove and a window through which deposits may be observed. The housing has a plastic base 14 in which is embedded a threaded metal discharge passage 18 by which the filter is secured on and connected to an I.C. engine, sealing being effected by ribs 25 moulded in the base. Inlet passages 19 are slanted to increase turbulence, and a gasket 48 backed by a spring 47 closes the passages on the occurence of excess pressure within the housing. To facilitate rotation of the unit, the top part of the housing may be formed with flats and a nut 28, with recesses for mating engagement with different tools, may be embedded in it. Alternatively, it may be formed with parallel projections for engagement by a simple key, Figs. 6-8 (not shown).

Title: Improvements in window cleaning devices
IPC: A47L1/03
Filed: 1922-01-25
Abstract: 191,624. Copp, W. Jan. 25, 1922. Windows and the like, cleaning.-A device for cleaning both sides of a window simultaneously comprises two lazy-tongs carrying wipers and connected so that any movement imparted to the inside wiper is followed by the outside wiper. Holders 33 for the wipers are carried by lazytongs 6, 7 whose bottom members 13, 14 are attached to U-shaped members 11 pivotally mounted on pins fixed to shafts 9, 10 which may rotate freely in a bracket 8, the bracket being pivotally mounted in a frame 19 fixed to a clamp adapted to be secured to the window-sill. The clamp comprises two cross-bars 23 pivoting on a pin 34 which also, carries pivotally the frame 19, each end of the cross-bars having an upright projection 24; the bars are made to approach each other by a screw 28 so that the two pairs of uprights grip the sill. Slotted guide-bars 21 for the lazy-tongs are pivotally mounted in the bracket 8 so that they may be swung away from the glass, carrying with them the lazy-tongs which pivot about the pins through the shafts 9, 10; these guide-bars are connected by intermeshing toothed quadrants 22 adapted to pass through an opening in the bracket 8. As the inside wiper is moved over the glass, or away from the glass to surmount obstacles, the outside wiper will move identically due to the rotation of shafts 9, 10, the rocking of the bracket 8 and the turning of the quadrants 22. When the wipers require changing the lazy-tongs are collapsed, the inside guide-member 21 swung away from the glass until both lazy-tongs are horizontal; the apparatus may then be rotated about the pivot-pin 34, after a catch 31 which normally locks the frame 19 against rotation has been released, and the outside' wiper brought inside.

Title: Improvements relating to pallet transfer mechanisms
Inventor: ROBERTS BARRY SAMUEL
IPC: B65G59/06
Filed: 1964-01-18
Abstract: 1,075,821. Suction lifting devices; pallet loading machines. LAWRENCE ENGINEERING CO. Ltd. Dec. 30, 1964 [Jan. 18, 1964 (2)], Nos. 2291/64 and 2292/64. Headings B8C and B8H. A stack 15 or 16, Figs. 1, 2 (not shown), of pallets is placed in a pallet magazine 10 on a pallet magazine conveyer 14 in its upper (dashed line) position. Side walls 65, Fig. 6 (not shown), are manually adjusted previously so as to centralize the stack. If a stack 15 of skidstack (i.e. of fibre board form) pallets is used the conveyer 14 is lowered (full line) and actuated in unison with a-storage station conveyer 17 to feed the whole stack 15 into a storage station 11, whereupon :a further stack 15 of pallets may be placed in the.magazine 10. As each pallet is required in a further station 12, Fig. 1 (not shown), for loading, suction heads 29 on a transfer frame 19 are lowered to contact and then support the uppermost pallet, the frame 19 being then transferred to the further station 12, by movement on rollers 20 along horizontal guide channels 21 under the action of a ram 23 whereupon the pallet is deposited on a loading conveyer 22 in its lowermost (full line) position. If non-skidstack pallets 16 are used the conveyer 14 is lowered from its upper (dashed line) position during which lowering holding means 50 (adjustable for different sizes of pallets) are actuated to effect engaging contact with the lowest pallet but one to support it and the pallets above it. When fully lowered the conveyer 14 is actuated in unison with the conveyer 17 to feed the lowest pallet to the storage station 11. The conveyer 14 is elevated once more to contact the held pallet, the holding means 50 released and again, as above, re-actuated to grip and support the lowest pallet but one. When a pallet is required in the further station 12 the conveyers 14, 17, 22 are activated in unison to pass the pallet in the storage station 11 on to the (lowered) conveyer 22 and the pallet on conveyer 14 on to the conveyer 17. Whichever form of pallet is used it is carried on the conveyer 22 to the latter's uppermost (dashed line) position. As soon as an operator has assembled a layer of articles to be loaded on a loading platform 40 a stripping plate 41 is protracted, a stop bar 44 is operated and said layer is carried by rollers (not shown) on to the plate 41. The operator proceeds to assemble a further layer when the plate 41 is withdrawn and the articles slide over an apex plate 43 to be deposited gently on the pallet. The conveyer 22 is lowered slightly after each layer is deposited so that a stack of the requisite number of layers is built up. Thereupon the conveyer 22 is fully lowered (full line) andactuated to pass the pallet and stack of articles on to a delivery conveyer 37. A fresh pallet is simultaneously fed on to the conveyer 22 by either the suction transfer frame 19 or the storage conveyer 17 according to the form of pallet being handled.
