Title: Improved manufacture of cork composition
IPC: C08L97/00
Filed: 1937-02-01
Abstract: A cork composition having substantially the unimpaired properties of cork itself comprises cork granules and a binder of bodied tung oil and glue, the quantity of binder being only that sufficient to cement the cork granules together.  The term glue includes gelatine, albumen, and casein.  The tung oil is bodied by being heated in an open kettle to 450-500 DEG  F. for about an hour when the oil is in such a state that when a rod is dipped therein and raised a string is formed.  The heated oil is mixed with a softening agent for cork such as glycerine, glue and a hardening agent, e.g. formaldehyde, paraformaldehyde or hexamethylenetetramine, is added and the cork granules are coated with this binder and moulded to shape.  Suitable proportions are four pounds of glycerine, one pound of bodied tung oil and one pound of glue.  Glycol or sulphonated castor oil may replace the glycerine when the cork composition is not to be used for beverages.  Synthetic resins, e.g. phenol-formaldehyde, urea-formaldehyde, cumarone or alkyd resins, natural resins, e.g. copals or dammars, or mixture of resins may be added to the binder, and also waxes.  Suitable proportions are two pounds of tung-oil-glue-glycerine mixture, one pound of phenol-formaldehyde resin and four ounces of hexamethylenetetramine.  Three pounds of the binder are used to coat 12 to 13 lb. of cork granules.ALSO:A cork composition having substantially the unimpaired properties of cork itself comprises cork granules and a binder of bodied tung oil and glue, the quantity of binder being only that sufficient to cement the cork granules together.

Filed: 1942-03-12
Abstract: 581,404. Conveyers for washing and like machines. DETREZ, R. March 12, 1942, No. 3280. Convention date, Nov. 7, 1940. [Class 78 (i)] In a device for feeding bottles and other containers to washing or like machines the containers are fed to the machine in an upright position by a conveyer from which they. are transferred horizontally to one or more platforms having a vertical rising and falling movement whereby the containers are delivered upwardly to boxes in the machine and removed downwardly therefrom after treatment. In the embodiment shown, bottles are fed to a washing-machine by an endless-chain conveyer 1, Fig. 1, and are transferred by a pusher 7 to a platform 5, Figs. 1, 2, which is then moved vertically to lift the bottles into a row of boxes 3, Fig. 4, on the conveyer of the washing machine. This row of boxes is then moved forward one step towards the rinsing machine and at the same time a platform 5a, movable with the platform 5, receives a row of washed bottles from a row 3a' of boxes, and this platform together with the empty platform 5 is then moved downwardly to its lower position shown in Fig. 2. Push rods 7, 7a now move forward together whereby a fresh row of dirty bottles are transferred from the conveyer to the platform 5 and the clean bottles on the platform 5a are transferred to the discharge run 9 of the conveyer. The support 10 of the push rod 7 is reciprocated by means of driving shaft 23 through a cam 14 and rods 11, 12, 13 while the support 15 of the pusher 7a is connected to the support 10 by a tappet 16. Stepwise motion of the boxes 3 is effected from the driving shaft 23 through a crank 19 on a shaft 20 rotated periodically through gear wheels 21, 22, the gear 21 being freed periodically from the shaft 20 by a clutch 24 and the crank operating through a rod 25 a ratchet wheel 26 keyed on a shaft 27 to which are secured wheels 28 geared with chains supporting the boxes.

Title: Purifying isopropyl chloroformate by distillation
IPC: C07C69/96
Filed: 1954-02-04
Abstract: <PICT:0757742/III/1> Phosgene is separated from isopropyl chloroformate prepared by the action of phosgene on isopropyl alcohol by feeding the reaction product into the upper section of a fractionating column up which is flowing a vapour stream from a boiling pool of isopropyl chloroformate contained in the base of the column or in a reboiler connected to the base thereof: some of the liquid is continuously withdrawn from this pool and is cooled to below 40 DEG C., the operations being so conducted that the withdrawn isopropyl chloroformate is cooled within 15 minutes of its introduction into the column.  Vapours comprising phosgene and isopropyl chloroformate are withdrawn from the head of the column, and are cooled to a temperature between 10 DEG  and 30 DEG C. whereupn isopropyl chloroformate condenses leaving purified phosgene in the gaseous phase.  The condensate is returned to the column as reflux.  A mixture of phosgene and isopropyl chloroformate is fed through line 4 into the top of column 1 which is about 10 feet high and has a diameter of 12 inches.  The column, which is packed with 1/2 -inch ceramic Berl saddles, is heated at the base by steamcoil 3 which maintains the pool of isopropyl chloroformate in still-pot 2 boiling at a temperature between 95 DEG  and 99 DEG C.  The vapours reaching the head of the column are passed via line 6 to watercooled condenser 5 which is maintained at about 25 DEG C.; and the resulting liquid and gas phases are separated in separator 7. Gaseous phosgene is removed from the system through pipe 8.  The condensate is added to the feed at 9 and returned to the column. Isopropyl chloroformate of 98 per cent purity is removed from still-pot 2 by a constant level take-off pipe 10, and is cooled in heat-exchanger 11, and withdrawn to storage.  The rate of feed, of boiling, and of reflux return are adjusted so that isopropyl chloroformate remains in the system for about 5 1/2 minutes prior to being cooled in heat-exchanger 11.  Of this time, the delay is 4 minutes in the pool in still-pot 2.

Title: Improvements in, or connected with, Percussion Fuses for Projectiles.
Inventor: VOGT CLARENCE WEDEKIND
IPC: F42C15/26
Filed: 1918-03-04
Abstract: 130,659. Vogt, C. W. March 4, 1918. Projectile fuses, percussion. A delay-action on impact is produced by the torsional and expansive action of a spring controlling the release of the firing-plunger. In the construction shown in Figs. 2, 3 and 6, the plunger 3 has side wings 4 and is housed in a part 2 shaped to accommodate the wings.. A compressed coiled spring 8 is connected to the plunger and to the base plug 1. Balls 9 normally lock the plunger against forward movement. On discharge, the plunger sets back, and is then free to be rotated relatively to the fuse body, by the forces set up by the rotation of the shell, into the position shown in Fig. 6. In this position, the spring 8 is under torsion, and the balls 9 move outwardly as shown, into notches 7. By engagement with lugs 11 on the plunger, the balls prevent reverse rotation of the plunger, which is prevented from forward movement by the walls of the housing 2. When impact occurs, the balls move forward, releasing the plunger, which is then rotated backwardly by the spring 8 into the position in which it is free to be thrust forward by the expansion of the spring and fire the primer (not shown) In a modification, tangential springs oppose the initial rotation of the plunger and aid in restoring it to the position in which it can advance. Fig. 14 shows a further modification in which the plunger 3<a> is housed in a sleeve 2<a> having spiral grooves 31 with which the locking-balls 9<a> engage. On discharge, the plunger sets back, and is caused to rotate within the sleeve by the action of the spiral grooves, the balls passing into apertures 32 when in the rear position, the spring 8 then being under torsion and compression. On impact, the sleeve 2<a> advances, overcoming a locking-ring 25 and carrying with it the plunger. The plunger and sleeve are then rotated together by the spring until the balls 9<a> are free to escape into apertures 33 in the fusebody. The spring 8 then thrusts the plunger forward against the primer. A further construction which is described and shown somewhat resembles that shown in Figs. 2 and 3, but in this case a torsional stress is imparted to the spring when the fuse is assembled, and, in operation, the plunger is rotated in two stages in the same direction, the first step occurring on discharge, and the second when impact has occurred, prior to the forward movement of the plunger against the primer effected by the expansion of the spring.
