Patent GB-737419-A (GB)
Title: Process for the preparation of tropinone derivatives
Filed: 1953-04-02
Abstract: The invention comprises tropinone derivatives having the general formula <FORM:0737419/IV (b)/1> where R1 = H, CH3 or C2H5.  The tropinone derivatives are prepared by treating malic dialdehyde with ammonia or with amines having the general formula H2NR2 where R2 is CH3 or C2H5 and with acetone dicarboxylic acid in the presence of buffering substances, at a pH of 3.5-9.  A weakly acid aqueous solution of malic dialdehyde is, for example, added to a solution of acetone dicarboxylic acid and methylamine and the reaction mixture is buffered to the required pH with e.g. sodium acetate and allowed to stand at room or slightly elevated temperature.  The solution is made alkaline and 6-hydroxy tropinone is extracted with a water-immiscible organic solvent, e.g. ether, chloroform, benzene or toluene.  In the example a weakly acid, aqueous solution of malic dialdehyde prepared by hydrolysing 2,5-diethoxy - 3 - hydroxy - tetrahydrofurane, is added to a solution containing acetone dicarboxylic acid, methylamine hydrochloride and sodium acetate in water the pH being adjusted if necessary with dilute hydrochloric acid or caustic soda.  The reacted mixture is made alkaline with potassium carbonate, saturated with salt and extracted with chloroform.  The chloroform extract is evaporated to dryness and the residue is crystallized from a mixture of alcohol and ether optionally after distillation.  The picrate was formed by treating the ketone with aqueous picric acid and crystallized from alcohol.  Specification 729,971 is referred to.

Title: Teaching machine
Inventor: FERRIS MAXIME
IPC: G09B7/073
Filed: 1970-02-27
Abstract: 1299000 Teaching machines M FERRIS 27 Feb 1970 9704/70 Heading G5G An electrically controlled multi-student teaching machine is such that a question presented to all the students has to be responded to within a set time, after which the machine records each student's response or failure to respond. Fig. 1, shows the control circuitry and Fig. 2 the recording means. In use, a switch 10 is momentarily closed (by a teacher) after the students have been presented with a question. When the switch 10 re-opens the coil 202 of a relay 200 is energized for a period determined by a thermal time-delay device 300. Any response made by a student via a switch 16, (there being one such switch for each student) will, so long as the coil 202 is energized, also energize the coil 402 of a relay 400 at that student's position, thereby sending an output signal to a meter 24 which displays the total number of responses. When the relay coil 202 has been de-energized at the end of the delay period, relays 400 which have been energized will be held-in by their contacts 404 and respective solenoids 22 will be energized by way of contacts 406 of the respective relays 400, and a contact 504 common to all students. The contact 504 is in a relay 500 whose coil 502 is energized via a transistor amplifier 20 when the relay 200 is de-energized. Thus, at the end of the delay period, a solenoid 22 is operated for each student who has responded. In the recording device of Fig. 2 the solenoids 22 (only one of which is shown, but a plurality in fact being provided) control respective markers 70 which overlie a record sheet (not shown) capable of step-by-step advancement along a table 32 by means of sprockets 58. The sprockets are advanced by one step whenever the teacher's switch 10 is momentarily closed. Closing the teacher's switch also clears the students' relays and generally resets the apparatus for the next questioning operation. The foregoing description relates to a "yesno" type of questioning, in which each student either responds positively or not at all. More elaborate circuitry (Figs. 5A and 5B, not shown) may be provided to allow for more complex question-and-answer techniques. In particular, the questions may be in the form "is such-and-such a statement true?" a response being required only if it is true, so that the record must identify positive answers as correct in the case when the statement is true but as incorrect when the statement is false. In such use, the responses may be so scored that true-calledtrue ranks + 1 mark, false-called-false (i.e. not responded to) also ranks as + 1, true-calledfalse ranks as 0 but false-called-true ranks as -5. Such a system penalizes mere guessing.

Title: Improvements in apparatus and method for preserving eggs and fruit
IPC: A23B5/06
Filed: 1929-03-27
Abstract: 335,586. Benoit, L. March 27, 1929. Preserving eggs and fruit.-Eggs and fruit are preserved by submitting them to a partial vacuum and then treating while in the evacuated condition with petroleum oil or wax in the form of a heated vapour so as to coat the article undergoing treatment and seal it against contamination. The petroleum oil or wax is steam distilled and introduced in the vapour form together with steam, only sufficient time being allowed to permit of the article becoming coated with the condensate. Condensation may be accelerated on the surface of the foodstuff by admitting refrigerated air to the treating chamber. A suitable apparatus is shown in Fig. 1 in which the eggs or fruit are contained in a case B provided with a number of individual and interconnected cells formed by the intersecting strips 22 and 23. A perforated inlet pipe 27 is so arranged that the preserving agent entering the case has free access to all the cells. The case B is delivered by a conveyer C and enters the treating chamber by the door 14, after which the chamber is closed and connected with a source of vacuum by means of the control valve 17. The preserving agent is then introduced through the steam valve 19, followed if necessary by the admission of refrigerated air by means of the valve 21. The case is finally passed through the opposite door 14 and removed by the conveyer D. A modification is shown in Fig. 2, in which a single conveyer F is used which moves intermittently. Upon the conveyer is mounted at intervals a plurality of beds A, each bed being adapted to receive thereon a case B containing the food product. Co-operating with the bed is a vertically movable hood E adapted to rest on the base when the latter has advanced to a given position. A further modification is shown in Fig. 3 in which is used a fixed bed A having rollers 10 adapted to support a case B which may be brought to operative position on a conveyer C, and removed subsequently to the treatment on a second conveyer D. The upper portion of the treating chamber is in the form of a hood E separable from the bed by a vertical movement. Various accessory features of the apparatus are described and shown by means of which the travel of the case is arrested at a predetermined position in the treating chamber, and by which the case is ejected from the bed after the treating operation, the action of the stop and the ejection being governed by the hood movements. The case in which the eggs or fruit are treated is suitable for storage, so that only one filling operation is necessary.

Hydrocarbons, distilling; rectifiers. - In frartionatihg oil vapours so as to obtain a fraction of definite boiling- point range, the vapours are passed through a dephlegmator 11 from an inlet 12 to an outlet 18 and are washed by cold condensate delivered by a pipe 42 on to the upper tray of the dephlegmator. The condensate condenses all the higher boiling fractions and at the same time absorbs lower-boiling vapours, which are subsequently separated in a still 21. The liquid from the base of the dephlegmator passes by a pipe 19 and is divided into two streams, one stream passes through a pipe 25, tubes 24 traversing the still and a cooler 34 from which it is forced by a pump 41 to the top of the dephlegmator. The other stream passes by a pipe 26 into the still 21 which has partitions 27 dividing the vapour space into compartments which have separate vapour outlets 28. Steam is injected into each compartment through perorated pipes 20. The liquid freed from light fractions is withdrawn through a pipe 29.
