Patent GB-378009-A (GB)
Title: Improvements in and relating to means for the hydraulic transmission of power
IPC: B23B47/22
Filed: 1931-04-29
Abstract: 378,009. Hydraulic transmission of power. NATIONAL AUTOMATIC TOOL CO., Richmond, Indiana, U.S.A.-(Assignees of Schafer, R. A. ; 211, South 15th Street, Richmond, Indiana, U.S.A.) April 29, 1931, No. 19389/32. Convention date, Sept. 26, 1930. Divided on 378,003. [Class 69 (ii).] In hydraulic mechanism for reciprocating a machine part, e.g. the head of a multipledrilling machine, the controlling valve means is shifted by manual means to a neutral position, and is thereafter automatically moved to operative position upon release of the manual means ; actuation of the manual means during the working cycle effects reversal. The control valve 21, Fig. 4, functioning in the manner described in Specification 378,003 is connected to a member 45, Fig. 2, acted on by a spring 51 tending to urge it to the left. Depression of a pedal acts through a lever 97 to move the member 45 and valve 21 from a final neutral position to the initial neutral position shown in Fig. 4, a spring-pressed latch bolt 67 carried by a member 62 engaging a recess 77 in the member 45. The release of the pedal allows the spring to move the member to the left to an extent limited by the recess 77, thus setting the machine part in motion at a rapid rate ; when a stop 88 on the machine part has cleared a lever 83, a spring 80 moves the member 62 downwardly to remove the bolt 67 from the recess 77, so that the member 45 is moved to the left until the member 62 is in contact with a step 61. Other stop members on the machine act in succession on the lever 83 to raise the member 62, each lift of the latter allowing the spring to move the member 45 to the left to bring its next step into contact with the member 62. The valve is thus moved successively through positions forgiving the machine part slowforward and rapid reverse motion, to a second neutral position. Depression of the pedal at any time during forward motion causes a cam surface on the lever 97 to act on a lever 92, and so lift the member 62 sufficiently far to enable the valve 21 to move into the position of Fig. 8 for reverse motion, a latch bolt 66 engaging a recess in the member 45 to prevent subsequent movement to the right as a result of continued depression of the pedal ; at the end of the reverse motion, the stop 88 acts to allow the valve to assume its final neutral position.

Abstract: 634,678. Sparking-plugs; fuel injectors. AMERICAN BOSCH CORPORATION. July 21, 1947, No. 19494. Convention date, Oct. 13, 1945. [Classes 7 (iii) and 7 (iv)] A combined fuel injector and high frequency sparking plug comprises a hollow conductor 30, connected to a magneto or induction coil, through which flows fuel to a pipe 28 and nozzle 25 forming one electrode of the sparking plug, the conductor 30 being also connected to an oscillator gap 24 earthed at 7, and to a terminal 31 of a condenser 23 whose other terminal 33 is connected to the hollow conductor 28 insulated from and electrically shielded by a member 17. The pipe 28 is connected through a screwed conductor 27 to an earthed primary winding 13 formed on an insulator 11 and to a secondary winding 14 connected by a spring 26 to the electrode 25, the other electrodes 16 being earthed. Discharge across the gap 24 produces a surge in the primary 13, which induces a sufficiently high voltage in the secondary 14 to result in a spark at the electrodes 16, 25. The fuel flowing to the nozzle 25 fills the spaces around the windings 13, 14 and acts as an insulator. In a modification the condenser is wound with the primary 14 in the part 12 of the body. Specification 619,947 is referred to.
Patent GB-771417-A (GB)
Title: Recovery of glutamic acid
Filed: 1955-07-06
Abstract: Glutamic acid is recovered from sulphuric acid hydrolysates of proteinaceous materials by neutralizing, concentrating, removing insoluble material, adjusting the pH of the filtrate to 2.8-3.5 (preferably 3.2) with sulphuric acid, quickly heating to 65-100 DEG C. and maintaining such temperature for 5-30 minutes, separating insoluble material immediately, cooling and crystallizing glutamic acid.  The initial neutralization is carried out by adding lime to pH 4-7 (preferably 5-6.5) and filtering before concentrating.  It is desirable to add carbon to the acidified filtrate before heating, and the preferred temperature is 80 DEG  C. for 15 minutes.  Examples show the hydrolysis of sorghum gluten, wheat gluten and corn gluten followed by treatment as above to obtain crystalline glutamic acid of low ash content.

Title: Code-controlled apparatus
IPC: H04L15/26
Filed: 1945-07-31
Abstract: 618,235. Type-printing telegraphy. WINTER, A. C. July 31, 1945, No. 19717. Convention date, Dec. 28, 1943. [Class 40 (iii)] [Also in Group XXXVII] Code-controlled apparatus employing a code of the kind in which the intelligence conveyed is determined by the lengths of the code-signal elements, and possibly also by their sequence (e.g. the Morse code) is similar in principle to that described in Specifications 618,225 and 5 618,234. It differs in that a code-element is measured and compared directly with a regulator value instead of with a code-space value whose magnitude is limited by a regulator. As described, the apparatus differs from the embodiments of Specification 618,234 in that the code voltage is compared directly with the regulator voltage instead of with the codespace voltage, and only one translator unit is provided for effecting these comparisons, instead of a plurality of such units. The receipt of a code-element charges a code condenser CC (Fig. 1) via a code diode CD and the resultant charge is applied to the grid of a triode CRV in opposition to the regulator voltage which is applied via the regulating rheostat 406 to the cathode. Current flows in the triode anode circuit only when the code condenser voltage exceeds the regulator voltage, i.e. the anode relay 600 operates when a dash is received. This supplies battery via a distributer switch 137h to operate a selected selflocking electromagnetic switch 1PR2 ... 4PR2 of a permutation device. A corresponding switch 2H ... 4H is independently operated via a distributer 137H whenever either a dot or a dash is received. Printing, word spacing and the discharge of letter and word condensers LC, WC respectively take place in a manner similar to that of Specification 618,234. The code condenser CC is discharged at the beginning of each received space. Automatic regulation is provided by a circuit (Fig. 5, not shown) which may be switched in at points 440, 441 as in the above Specification. In a modification (Fig. 6, not shown), three-position switches are employed for the permutation device, as in a modification of the above Specification, but they have an additional set of locking contacts, and the dash coil is made strong enough to hold the armature operated against the pull of the short strong spring, since the dot coil is de-energized at the end of a dash signal.
Patent GB-197464-A (GB)
Abstract: 197,464. Higginson, J. March 8, 1922. Interrupters, mechanical; switches partly electromagnetic. - In a mechanical interrupter for use in ignition systems a rotating cam-carrying member g is adapted to bring contacts a, b mounted on spring blades c, d into engagement. An electromagnet h is thus energized, attracting an armature on the spring c and causing a sudden interruption of the ignition circuit at a, b irrespective of the speed of the rotating cam. The free ends of the blade springs c, d are normally pressed against the lower of pairs of motion-limiting stops e, f. The cams on the member g are cf small width so that the contacts a, b are only separated once at each operation of a cam.

Title: An Improved Method of Electrically Welding Iron, Steel, Brass and other Metallic Studs and the like to Iron, Steel, or other Plating and the like.
Inventor: FRANKLING ALBERT EDWARD
IPC: B23K9/20
Filed: 1918-11-30
Abstract: 134,393. Frankling, A. E., Steele, L. J., Martin, H., and McCarthy, A. E. Nov. 30, 1918. Heating by electricity.-Studs are electrically welded to plates by closing the welding circuit with the stud and plate in contact, withdrawn ; the stud to strike an arc and after a time interval, again forcing the stud into contact with the plate. In the circuit system for operation, a hand switch 47 closes the circuit through solenoids 5, 6 of an electro-magnetic holding-on apparatus. Switches 50, 53 are then closed and a solenoid 57 closes the welding circuit 58 just before the solenoid 2 draws away the stud 40 thus striking the arc. After the predetermined interval the time switch 50 opens, breaking the solenoid circuit and permitting a spring to return the stud into contact with the plate 48. The rise of current in the welding circuit up to the limit provided for by the resistance 64 opens the switch 60, thereby cutting out the solenoid 57 and allowing the circuit breaker 58 to open. The solenoid 63 is fitted with a time-lag device, and a high resistance shunt is provided at 59. In a modification, the solenoid 2 is provided with a reversed or neutralizing coil brought into operation by the closing of a time switch.

Abstract: 940,137. Polymerizing alpha-olefins. MONTECATINI SOC. GENERALE PER L'lNDUSTRIA MINERARIA E CHIMICA. May 24, 1962 [May 29, 1961], No. 19986/62. Addition to 891,646. Heading C3P. Polymers of alpha-olefins are made by polymerizing the monomeric olefin in the presence of a catalyst system comprising activated TiCl 3 , an aluminium dialkyl monohalide, and a complex obtained from a zinc dihalide e.g. ZnCl 2 , and a nitrogen-containing organic base in amount such that the molar ratio of the zinc compound to the TiCl 3  is at least 0À05. The preferred olefin is propylene. The polymerization is generally effected in a hydrocarbon diluent. The nitrogencontaining organic base may be pyridine, quinoline, or isoquinoline. The polymer is recovered by conventional techniques, and it may be separated into fractions by solvent extraction methods. Activated TiCl 3  is described by Natta, G., in J. Polymer Sci., 1961, 51, 399-410.
Patent GB-692903-A (GB)
Title: Process for the preparation of aluminium triformate
IPC: C07C51/41
Filed: 1951-08-24
Abstract: Aluminium triformate is prepared by reacting an aqueous solution of formic acid with an aluminium soap of a water-insoluble carboxylic acid containing 8 or more carbon atoms, the concentration of the formic acid solution being such that the solution of aluminium triformate produced is supersaturated at room temperature, separating the aluminium triformate from the free carboxylic acid formed and drying the aluminium triformate thus separated.  The aluminium soap may be prepared by double decomposition between an aqueous solution of an alkali metal soap of the insoluble carboxylic acid and an aluminium salt such as the sulphate or chloride.  The soap may be formed from such acids or mixtures thereof as caprylic, lauric, palmitic, stearic, oleic and naphthenic acids and palm oil or coconut oils; preferably such a mixture of acids is used as yields an aluminium soap melting in the region of 100 DEG  C., whereupon an excess of the acid is added to reduce the melting-point further, so facilitating washing of the soap.  In an example, a mixture of fatty acids solidifying at 25 DEG  C., are neutralized with caustic soda at 50 DEG  C., and a solution of aluminium sulphate mixed therewith; the resulting aluminium soap is washed and mixed with a further quantity of fatty acid to reduce its melting-point whereupon formic acid solution is added at 40 DEG  C. to form a solution of aluminium triformate of 60-90 per cent concentration; two layers form, the lower layer of supersaturated aluminium triformate trihydrate solution being sent to a crystallizer and then dried and all or part of the upper layer used to form fresh aluminium soap for subsequent reaction.
Patent GB-491111-A (GB)
Title: Improvements in and relating to artificial filaments, films and like materials
IPC: D01F6/60
Filed: 1937-07-20
Abstract: Artificial filaments, films, and like materials made of polymeric amides of the kind described in Specification 461,237, are treated with water, isobutanol, or other non-solvent containing hydroxyl groups, and are then subjected to cold-drawing while still wet.  The water or other non-solvent may be in liquid or vapour form.  The preferred polymeric amides are those obtained by condensation of diamines of the formula NH2(CH2)x NH2 with dicarboxylic acids of the formula HOOC(CH2)yCOOH where x is at least 4 and y at least 3. Polyamides obtained from hexamethylene diamine and adipic acid or from decamethylene diamine and adipic acid may be employed. Filaments or films may be obtained directly from a molten mass of the polymeric amides or by extrusion of a solution of them in a solvent into a coagulating bath or heated chamber.  Cold-drawing is effected at ordinary temperature or at a raised temperature provided that the material is below its melting point and in the solid state.  The filaments may be spun and cold-drawn in a moist atmosphere or they may be sprinkled with water before being cold-drawn.  Thick filaments such as those used as bristles, horsehair or mohair substitutes are preferably soaked in hot water prior to the drawing operation.  Water or other hydroxyl non-solvent may be added to the spinning solution which may contain phenol as the solvent.  If the coagulation bath contains water, isobutanol, or like non-solvent, the cold-drawing may be carried out in this bath but it is preferably effected outside the bath.  In spinning polyamides from a phenol or acid solution, aqueous alkaline coagulation baths such as dilute solutions of caustic soda or sodium sulphide may be used.
