Title: Recovery of Glycidol
Inventor: NAGLIERI ANTHONY NICHOLAS
IPC: C07D303/14
Filed: 1967-07-20
Abstract: 1,183,360. Recovery of glycidol. HALCON INTERNATIONAL Inc. 20 July, 1967 [25 July, 1966], No. 33346/67. Heading C2C. Glycidol is recovered from a feed mixture comprising glycidol, allyl alcohol and higher boiling materials by conducting a first distillation of said feed mixture whereby a first overhead product and a first bottoms product are obtained, said first overhead product comprising allyl alcohol and said first bottoms product comprising glycidol substantially free from allyl alcohol, and conducting a second distillation, which is applied to the said first bottoms product, in the presence of a hydrocarbon azeotropic agent which forms a low boiling point azeotrope for the recovery, as a second overhead product, of a glycidol-azeotropic agent azeotrope. The glycidol azeotrope may be extracted with water to recover glycidol substantially free of the azeotropic agent in the form of a water solution of glycidol. Subsequently the water may be removed whereby substantially pure glycidol is obtained. The azeotropic agent is suitably a hydrocarbon and particularly useful are the aliphatic, naphthenic and aromatic hydrocarbons having the same skeletal carbon structure as the hydroperoxide employed in the epoxidation reaction wherein allyl alcohol is converted to glycidol. Those specified are ethylbenzene, cumene, benzene, toluene, pethyltoluene, isobutylbenzene, tetralin, diisopropylbenzene, xylenes, cyclohexane and alkylsubstituted cyclohexanes. In one embodiment, the distillation is conducted in the presence of a hydrocarbon azeotrope which forms a low-boiling azeotrope with glycidol, but which does not form an azeotrope with allyl alcohol, e.g. cumene, and in another embodiment the distillation is conducted in the presence of a hydrocarbon which forms two separate low boiling azeotropes, first with allyl alcohol and then with glycidol, e.g. ethylbenzene.

Patent GB-1529494-A (GB)
Title: Anchor bolt
IPC: F16B13/08
Filed: 1976-08-12
Abstract: In the case of a suspension member having an anchor bolt (1) which can be fixed in a bore, the anchor bolt (1) has a shank part and an expansion wedge (4) which is longitudinally displaceable thereon. A helical spring (5) supported on the anchor bolt (1) is locked in the prestressed position by means of a fixing lug (9) when the expansion wedge (4) has been drawn back. Once the shank part, with drawn-back expansion wedge (4), has been inserted into a mounting bore, the fixing lug (9) only has to be manually displaced, transversely to the longitudinal expanse of the anchor bolt (1), into a release position in order to permit the helical spring (5), in the longitudinal direction of the anchor bolt (1), to act against a stop (6) at the rear end of the expansion wedge (4) and to drive the latter forwards so as to wedge the anchor bolt (1) in the mounting bore. The suspension member is provided, in particular, for suspended ceilings.   <IMAGE>
Patent GB-486321-A (GB)
Title: Improvements in or relating to mechanical loaders for loose materials
IPC: E21F13/06
Filed: 1936-12-08
Abstract: 486,321. Endless-chain conveyers ; driving portable machines. SUTCLIFFE, Ltd., R., and SHEPPARD, J. Dec. 8, 1936, No. 33636. [Class 78 (i)] [Also in Group XXXI] A mechanical loader for loose materials comprises one or more pusher elements carried by and projecting laterally from positively driven endless chains, belts, or bands, the arrangement being such that as the point of attachment of a pusher passes around one end sprocket, the pusher is advanced laterally into the material, then pushes the material in front of it during its passage along one run, and then is withdrawn laterally from the material as the point passes around the other end sprocket. The pusher 1, Fig. 1, is mounted on the end of an arm 2 provided with apertures which are engaged by pins 6 fitted to links of parallel and similar chains 3. The end driving sprockets 4 are connected by spur gearing 5, Fig. 3. The pusher may be spring loaded so that it yields on meeting an obstruction. This movement may actuate a switch or gear for cutting off the drive when the load is excessive. The centre spur gear 5 is connected by a dog clutch 10 to a shaft 11 driven through spur gears 13, bevel gears 14 and worm gears 15 from an electric or air motor 12. The road wheels 16, Fig. 4, are driven intermittently from the shaft 17 of the worm 15 by the following gearing. A worm 18 on the shaft 17 drives a worm wheel 19 which in turn drives a ratchet wheel 20 through bevel gears 21, crank or eccentric 22, connecting rod 23 and oscillating pawl carrying arms 24. The ratchet feed is adjusted by a bevel gear sector 29 actuated by a bevel pinion 30 on the shaft of a controlling hand wheel 32 having an automatic stop incorporated in its bearing. The ratchet wheel 20 is coupled to a spur wheel 25 in mesh with a spur pinion 26 which is freely rotatable upon the ground wheel shaft 27, but may be coupled thereto by a sliding dog clutch 28 actuated through lever and link mechanism 33 when it is desired to drive the road wheels continuously, the clutch 28 is moved to couple a spur pinion 36 to the shaft. This pinion is driven from the shaft of the worm wheel 19 through bevel wheels 34 and a spur wheel 35. In a modification the endless chains, &c. 3 are mounted one within the other on end sprockets of different sizes and are driven so that they take the same time for each complete cycle. In a further modification one of the endless chains, &c. is passed around guiding sprockets in addition to end sprockets, the arrangement being such that the pusher will have an angular movement imparted to it as it commences its stroke. In all constructions two sets of endless chains, &c. may be employed opposite one another so that their pushers operate along the same path alternately.

Title: Improvements in or relating to pressure-operated flushing cisterns
Inventor: SCHOFIELD HUBERT PERCIVAL
IPC: E03D1/28
Filed: 1961-09-20
Abstract: 950,340. Valve-and-siphon-discharge waterwaste-preventers; ventilating closets. SHIRES & CO. (LONDON) Ltd. Sept. 17, 1962 [Sept. 20, 1961], No. 33639/61. Heading E1C. A pressure operated flushing cistern 5 comprises a pressure vessel 6 which is normally closed to atmosphere having an inlet 10 for connection to a supply of pressure liquid and an outlet 12 therefrom controlled by a valve 13 so that liquid entering the vessel 6 compresses air therein and is dischargeable therefrom under pressure on opening the valve 13, at least a major part of the air compressed by the liquid entering the vessel 6 being permanently retained within a resilient closed container within the vessel 6. The container is preferably a collapsible bladder 15 of e.g. rubber. There may be more than one vessel 6 connected through the valve 13 to a common outlet to the pan 4 at 14. A non-return inlet valve 11 may control the liquid entering the or each vessel 6, or several vessels 6 may have a single inlet valve 11 in a manifold 9 from which branch connections lead to each vessel 6. The outlet valve 13 may be connected to the manifold 9 which is entered by the liquid through a restricted throat whereby a Venturi effect is erected for exhausting the or each vessel 6 of liquid when discharging. Operation is by means of an electrical circuit controlled by a pedal 16, the outlet valve being solenoid-operated. In a modification an air inlet valve in the or each vessel 6 is operable during liquid discharge to ensure that all the liquid is discharged and there is an air outlet in the or each vessel 6 so that the air trapped therein can be reduced during filling, when the air expelled through the outlet may aspirate air from near a water closet pan 4 with which the cistern co-operates or to be fed back to the pan 4 after passing over or through an odour repellant. The or each vessel 6 may have an inverted U-tube, one leg of which is connected to the vessel outlet, the other leg being open to the liquid within the vessel 6, so that liquid discharge therefrom is also syphonic. The outlet valve 13 may be solenoid-operated so that its opening is initiated by a control-switch and it is closed automatically after a period of discharging the or each vessel 6. The valves 13 and air-inlet and -outlet valves may be all solenoid-operated, their operation in sequence during the discharge and filling cycles of the or each vessel 6 being under the control of timing means operated by a push-button switch and not a pedal.

Title: Improvements in or relating to wireless receiving apparatus
IPC: H03J1/04
Filed: 1937-12-06
Abstract: 512,772. Adjusting wireless apparatus. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Dec. 6, 1937, No. 33653, Void. Convention date, Dec. 5, 1936. [Class 37] [Also in Group XL] The tuning scale, arranged in front of the sound opening of the loud speaker, comprises a strip or a plurality of spaced strips bearing stations names or other indicia. Figs. 1, 2, show transparent strips 3, for example, of glass, bearing scale indications and, or station markings, and co-operating with a tuning pointer 4 mounted on a guide bar 6' and moved parallel to the direction of the strips 3 in known manner by the tuning control 5, the strips 3 being spaced to permit the egress of sound from the sound opening 2. A sound permeable textile sheet 8 covers the sound opening and is disposed behind the strips 3 which are illuminated by lamps 12. Alternatively, the lamps 12 may be located so that the strips are illuminated partly or wholly by reflection from the loud speaker diaphram 11. A further light reflecting sound permeable textile sheet may be provided across the front of a baffle 10 to enhance the lighting effects. In a modification, the strips 3, Fig. 3 (not shown) are opaque, for example, of sheet metal or mouldable material and carry indicating projections and separately formed letters for the station names which therefore appear as shadows against the illuminated textile screen 8. Alternatively, the station markings may be stamped out of the strips 3 so that the letters appear bright against the dark background of the strips. The scale bearing strip or strips 3 may alternatively, be mounted vertically and traversed by a horizontal pointer. The strips 3 may be supported by cross strips, the dial structure then forming a grille with relatively large openings so that substantially no resistace is offered to the passage of sound. The strip or strips 3 may also be formed to guide the sound. Thus, Fig. 6 shows the dial structure in the form of a single strip 3 having a conical sound directing guide on the rear thereof which houses lamps for illuminating the dial, and the tuning indicator comprising, for example, an optical system for projecting a light beam for forming a shadow on the dial.
