Title: Process for the production of anhydrous formaldehyde
Inventor: POBLOTH HELMUT
IPC: C07C45/78
Filed: 1961-03-09
Abstract: Anhydrous formaldehyde is obtained from formaldehyde vapours containing less than 10% by weight of water by washing the vapours with a liquid mixture of two components at a temperature of 0-100 DEG C., one component being one or more liquids miscible with water in any proportion and inert to formaldehyde and the other component being one or more liquids which dissolve less than 10% by weight of water and are inert to formaldehyde, and circulating the liquid mixture through a drying agent.  The component which dissolves less than 10% of water may be present as a proportion of 5-80% by volume. Liquids which are miscible with water in all proportions are, for example, cyclic ethers, amides, N-alkylated amines and lactones. Suitable liquids which will not dissolve more than 10% of water are saturated and unsaturated aliphatic, cycloaliphatic or aromatic hydrocarbons and hydrocarbon halides, esters, aldehydes, ketones and aliphatic and aromatic ethers. Suitable drying agents are, for example, silica gel, calcium chloride and phosphorus pentoxide. The process is particularly applicable to the treatment of formaldehyde obtained by thermal depolymerisation of formaldehyde polymers.

Title: Apparatus for washing minerals and other substances
IPC: B03B5/68
Filed: 1923-04-04
Abstract: 212,436. Henry, R. A. April 4, 1923. Upward - current classifiers; stationaryvessel washing-apparatus.-In apparatus for washing minerals of the type wherein a trough is traversed longitudinally by a classifying current which moves in a closed circuit, the lighter material is moved from the circuit by diverting from the main current a small current which is led back into the main circuit after being relieved of the material it carries. The separated materials fall under gravity to the bottom of a reservoir whence they are removed. To avoid choking of the circulating pump by mud, the latter is removed by scavenging apparatus before the material is admitted to the washer. The material is fed into the part 2 of the scavenging apparatus, where the heavy material falls, to be removed by the chain of buckets 5, whereas the light material is carried upwards into the part 7 by a current, assisted by an air blast delivered at 3. Further separation thereof is effected by means of a current in the part 8, the mud being drawn off at a passage 10. The heavier material removed by the buckets 5 is deposited in the trough 11 and sorted by deposition under the action of the current, the denser material falling through orifices 13 into a tank 12, and the intermediate material being carried round towards the passage 16 and circulating pump 14. The latter is only partially submerged so that air may be drawn in by it. The material in suspension in the circulating current traverses the overflow 15 into a tank 17 where it settles, the current therefrom returning via the overflow 18 to the closed circuit. Draining chains may be provided for the tanks 12, 17. A tap 21 supplies water to the tank 12 to prevent water descending through the orifice 13 and, for regulating the water level generally, a supply tap 22 and drawing-off tap 20 are provided.

Title: Improvements relating to metal and like drilling machines
IPC: B23B41/02
Filed: 1932-04-01
Abstract: 399,807. Drilling long holes. SERCKRADIATORS, Ltd. and SERCK, O., Warwick Road, Greet, Birmingham. April 1, 1932, No. 9339. [Class 83 (iii).] In a machine for drilling long holes in work such as billets, wherein the drill is fed axially by fluid pressure and the work is preferably rotated, means are provided for cutting off the pressure fluid when the drill encounters excessive resistance. The drill is then automatically withdrawn and returned to resume the drilling operation. The work b is rotated in a headstock a and the drill c is held in a socket e rotatably mounted in a holder f slidable in guides g on the machine frame by means of the ram d of a fluid-pressure cylinder r. Rotation of the socket within the holder is normally prevented by one or more spring plungers i engaging a longitudinal shoulder h on the socket, the plungers acting on levers k when the cutting torque becomes excessive so as to rock a shaft l and cause a detent on a bracket n carried thereby to be moved out of the path of the lever o, thus allowing a spring s, Fig. 3, to rock the lever and close the fluid-pressure valve q supplying the ram cylinder r. A weight y or a spring attached to the holder f then returns the drill until a stop 4 on the holder engages the lever n to open the valve and allow the drill to be fed to the work again, the detent n maintaining the valve lever in the open position. The machine may be controlled by manipulating the lever o or by switch control of the electric motor 5 which drives the fluid supply pump 6. The Provisional Specification describes a toothed sector and pinion mechanism for oscillating the shaft l when the cutting torque becomes excessive. Lubricating cutting tools and work.-Lubricant is supplied to the holder f and through the hollow drill by means of a pump 8 driven by the motor 5.

Abstract: 674,398. Plate heat-exchange apparatus. AKTIEBOLAGET SEPARATOR. April 20, 1950 [April 20, 1949], No. 9734/50. Class 64(iii). A plate heat-exchanger for the treatment of milk or like liquids having a regenerative section which is divided into a plurality of sub-sections and which is associated with a holding cell, is characterised in that the holding cell 31 is located between two of the sub-sections 11, 17 of the regenerative section and is provided with connections for connecting the subsections to the feed and discharge pipes of a centrifuge. Thus the holder cell comprises also the functions of a coupling plate. In the apparatus shown, milk to be processed enters the heating side of the regenerative sub-section 11 through an inlet 10 and passes through the sub-section 11, to and through an inlet connection 1 and an outlet connection 2 of the holder cell 31 (shown in detail in Fig. 4) to a centrifuge (not shown) where the cream is separated to be processed separately. The milk is returned from the centrifuge to the holder cell through an inlet 3 from which it passes through a passage 4 to the regenerative sub-section 17 where it receives further heat. Upon leaving the regenerative sub-section 17, the milk passes to the steam-heated heating section 21 of the apparatus where it is raised to pasteurizing temperature, after which it flows through a pipe 25 to an inlet 5 leading to the tortuous fluid passage 27 of the holder cell, from which it is discharged through an outlet 6 to the cooling side of the regenerative sub-section 17. The cooled milk passes from the sub-section 17 to and through a passage 7, 8 in the holding cell and through the cooling side of the regenerative sub-section 11 in which it gives up further heat and from which it is finally discharged through the outlet 30.
