Title: Method of producing soluble phosphate fertilisers
IPC: C05B11/08
Filed: 1927-04-20
Abstract: 282,619. Liljenroth, F. G. Dec. 23, 1926, [Convention date]. Manures.-Fertilizers consisting mainly of ammonium phosphate are prepared by leaching calcium phosphate with a mixture of sulphuric acid and a thin solution of ammonium sulphate, the latter being produced from calcium sulphate (separated in the process) by ammonia and carbon dioxide. Molecular proportions are preferably three of phosphate, seven of acid and two of sulphate, but excess ammonium sulphate prepared as above may be used and remains in the product. Potassium salts, e.g. chloride may be added. Specification 275,843 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the preparation of soluble phosphates by leaching crude calcium phosphate with an amount of sulphuric acid less than that corresponding to the calcium in the phosphate to give monocalcium phosphate and free phosphoric acid. The lime is simultaneously or subsequently precipitated as sulphate, by alkali or ammonium sulphate, leaving a soluble phosphate in solution. After filtering, the solution is neutralized, preferably with ammonia, and evaporated. If potassium phosphate is desired, caustic potash or a salt of a volatile acid e.g. potassium carbonate or chloride is used as neutralizing agent. Double salts e.g. potassium ammonium phosphate may be prepared by neutralization by mixed salts. Excess sulphuric acid may be used in leaching the crude phosphate, and soluble sulphate and further crude phosphate added later. This subject-matter does not appear in the Specification as accepted.

Title: Work piece feeder for machine tools
IPC: B23G11/00
Filed: 1973-03-06
Abstract: 1423572 Transferring workpieces A V KLANCNIK 6 March 1973 10843/73 Heading B3B [Also in Division B8] In a magazine-type feeder apparatus workpieces such as nuts WP, Fig. 1, or small electrical components WA (Fig. 5, not shown) drop under gravity down guideway 23 of the magazine to a spring-loaded holding detent 28. Feed finger 55, Fig. 2, on support 53 pivotally mounted on reciprocating slide 60 engages the workpiece WP2 and on reciprocation of slide 60 by, for example, fluid pressure cylinder mechanism (70-73, Fig. 3, not shown) the workpiece is forced past the detent 28 until it ejects preceding workpiece WP1 and is engaged by a spring loaded locating detent 40 which holds the workpiece in a working position for subsequent machining, e.g. tapping. The cylinder mechanism is then reversed and a cam follower pin 90 on support 53 which, on the advance stroke, followed cam surface 97 on a cam block 92, Figs. 2, 4, now rides up surface 96, 96A on a cam " switch " plate 91 held in position by spring 94. This retracts feed finger 55 which is raised while out of engagement with the workpiece. Pin 90 then traverses top cam surface 96E and the finger returns to its original position engaging a third workpiece. If the workpiece is not there due to jamming in the guideway 23, the feed finger engages a notch 90N in plate 20 and is prevented from any downward movement. In an alternative construction suitable for workpieces which cannot jam, e.g. components WA, the feed mechanism may be located on the same side of the mounting plate 103 as the tool T and the workpiece is fed by a finger 120 on spring loaded lever 125 on support block 132 reciprocated by piston 135, Figs. 6, 7. The workpiece is fed by the finger only to an intermediate position WA2, the preceding workpiece WA1 being fed thereby to the work station defined by detent 112. Follower pin 142 engages a resilient switch plate 145 on the front side of which, as shown in Fig. 7, the pin rides when the finger 120 is raised; when it is lowered the pin 142 engages a surface of the guide 133 for the reciprocating support 132 after passing through notch 145.

Title: New substituted piperazine compounds and processes for their preparation
Inventor: PAUL RAYMOND ETIENNE
IPC: C07D471/14
Filed: 1954-04-15
Abstract: The invention comprises isomeric 11,21/1,2 ,\ba11,21/4, 3 -bis-(31-hydroxypiperidino) piperazines of the formula <FORM:0763990/IV(b)/1> the corresponding diesters derived from monocarboxylic acids, the isomeric mixtures and racemates of said piperazines and esters thereof, and the acid addition and quaternary salts of said piperazines and diesters, and the preparation of the free piperazines by dehydrobrominating a bromohydrin of the formula <FORM:0763990/IV(b)/2> by treatment with potassium hydroxide, and optionally subsequently converting said free piperazine to the diester or to the acid addition or quaternary salt of said free piperazine or diester thereof.  The above process may be modified in that the bromohydrin is obtained by reacting ethylenediamine with furil to form 2,3 - di - (2 - furyl) - 5,6 - dihydro - pyrazine, the resulting pyrazine is hydrogenated in the presence of active nickel catalyst, e.g. Raney nickel, to form isomeric 2,3-bis-(2-tetrahydrofuryl)-piperazines (the dipicrate and dinitroso derivatives thereof are referred to in the examples) which are then treated with hydrobromic acid in acetic acid medium.  Esters referred to are the dibenzoic and bis-(diphenylacetic) acid esters.  The acid addition and quaternary salts preferably contain a therapeutically acceptable anion, mono- and dihydrochlorides, dipicrates and di-methiodides being specifically referred to.  A detailed example is given in which the a - and b -form of the free piperazine are prepared having melting-points of 170/171  DEG  C. and 148/149  DEG C. respectively.  The dipicrate salt and the bis-(diphenylacetic acid) esters including the dihydrochloride salts thereof and the dibenzoic esters including the monohydrochloride salts thereof of the a -and b -form of the free piperazine are also prepared.  The example also refers to the isolation of a small quantity of 2-(2-tetrahydrofuryl)- 1,21/4,3 - (31 - hydroxypiperidino) piperazine (the dipicrate salt of this compound is also mentioned) resulting from the incomplete reaction of hydrobromic acid with 2,3-bis-(2-tetrahydrofuryl)-piperazine, whereby one of the tetrahydrofuryl rings is not opened, which on prolonged treatment with hydrobromic acid, followed by potassium hydroxide, forms a mixture of isomers of the free piperazines of the above general formula.

Filed: 1959-04-03
Abstract: 908,144. Typewriters &c. ROYAL McBEE CORPORATION. April 3, 1959, No. 11466/59. Class 100 (4). A portable typewriter can be manually or electrically operated according to the position of a downstop bar 42. In manual operation key levers 24 actuate the type bars 11 directly through links 38 after a certain lost motion movement. In electrical power operation depression of the key levers is restricted by the bar 42 to the position shown in dotted lines in which the links 38 are not moved. Initial movement of a key lever 24 withdraws its abutment 26 from engagement with a corresponding pawl 18 allowing it to drop into the path of a universal actuating bar 17. A rearward arm 29 of the key lever 24 actuates a ribbon vibrator bar 32 which in turn actuates a plunger 36 of a switch 35. Actuation of the switch 35 changes over the connection of a capacitor from a power source, keeping it charged, to allow it to discharge through a solenoid causing the actuation of the bar 17 to cause the type bar 11 to strike. The time constant of the discharge circuit can be varied to simultaneously alter the striking force of all the type bars while the length of the pawls 18 is varied to adjust the striking force of each individual type bar. The pawls 18 then disengage from the bar 17 at different points allowing the type bars to strike by momentum. The power mechanism can be used to effect other typewriting functions such as back-spacing or carriage return.
