Title: Apparatus for feeding measured quantities of granular or pulverulent material into valve bags
IPC: B65B1/18
Filed: 1934-09-12
Abstract: 434,853. Packeting granular &c. materials in formed receptacles. BATES INTERNATIONAL BAG CO., 60, East 42nd Street, New York, U.S.A. Sept. 12, 1934, No. 26169. Convention date, Jan. 31. [Class 94 (i)] In a machine for filling valve-bags with weighed charges of granular or pulverulent material, the charge is compacted as it is fed to the filling nozzle by a tapering solidcore screw, while the bag is shaken up and down to settle the charge. The material is fed to the weighing hopper 14 with the assistance of a rotary agitator 13, and the weighing device 15 operates to close first the inner gate 16 when the greater part of the charge has been deposited and then the outer gate 17 when the charge is complete. The agitator 13 is stopped, and if desired a lamp is lighted to notify the operator. The handle 33 is raised bringing the clamp 31 downwardly to hold the bag in position and releasing the bottom gates 20 of the hopper 14. The charge falls into a shoot 22 having an agitator 26 and is fed to the filling nozzle 29 by a tapering screw 24. At the same time a shaft 47 is clutched to the driving shaft and by means of an eccentric thereon effects a jigging motion of the bag platform 51. The reduced resistance to the screw 24 when the bag is full may be utilized to light a lamp.

Title: Improvements in or relating to machines for making paper cups and like containers
IPC: B31B105/00
Filed: 1934-09-12
Abstract: 425,750. Making paper cups &c. JAGENBERG - WERKE AKT. - GES., 107, Himmelgeisterstrasse, D³sseldorf, Germany. Sept. 12, 1934, No. 26176. Convention date, Sept. 28, 1933. [Class 18] A machine for making cuplike paper vessels from a blank suitably shaped and glued together to constitute a substantially tubular wall and a bowl-shaped member adapted to be inserted therein to form the bottom of the vessel, is characterized in that a rotary table 21, upon which the formers 22 are arranged vertically, is rotatably mounted on a vertical stationary column 20 on the head of which are disposed the control parts of the tools operating on the vessel bottom. The bowl-shaped vessel bottoms are fed by a band 16 to a feed trough 17 being conveyed therealong by air blasts from nozzles 18, 19, the foremost bottom coming to rest on oscillatable bars 31, held in place by counterweights 32 or springs. The blanks for the tubular walls of the vessels are taken from a pile 1 by an oscillating suction picker and fed by an oscillating gripper device to grippers 10 carried by chains 8, 9, which carry each blank through a gumming mechanism to a folding device 29. The plunger 33 now descends, under the action of the cam drum 28, to press the bottom between the bars 31 and on to the top of the former 22. The gummed blank from pile 1 is now folded around the former 22 by the device 29, the presser plate 23 pressing the seam and is maintained in this position throughout the passage of the vessel in the machine. The rotary table 21 now carries the work piece to position II where a matrix 37, carried by rods 36, descends to surround the vessel bottom, a tool 38 turns in the bottom edge of the tubular wall and a tool 39, of star like cross section, descends and then rotates to press the turned-over end into position. At position III a plunger 40 and matrix 41, carried by a slide 43 and operated by a roller 45 in a cam groove on the head 24, and normally retained in the uppermost position by a locking pawl 46, descends to press the joint formed at position II. This pressure is maintained until position XIII when the plunger 40 and matrix 41 are raised by a cam-operated device 48, 49, the tools 40, 41 being retained in the inoperative position by the pawl 46 until station III is again reached. The formed vessels may be removed from the formers 22 by compressed air and delivered by a conduit 50.

Title: Means for indicating the reception of multilated signals in a printing telegraph system
IPC: H03M13/51
Filed: 1945-10-08
Abstract: 616,426. Type-printing telegraphy. MARCONI'S WIRELESS TELEGRAPH CO.. Ltd. Oct. 8, 1945, No. 26206. Convention date, Oct. 7, 1944. [Class 40 (iii)] A printing-telegraph receiver employing a code in which each character is represented by a combination of marks and spaces and in which the ratio of marks to spaces is the same for each character comprises an error-detecting device in which the area covered by a plurality of wedge-shaped members is varied in accordance with incoming signals. The device is described with reference to a receiver of the type employing a seven unit equi-ratio code and comprising internally notched code rings 1, Fig. 1, in which a stop-arm 2 rigidly fixed to a type-wheel shaft 9 has a homing position. On receipt of a correct code-signal the discs 1 provide an alignment of notches into which a spring-loaded roller 5 drops. An extension 3 of the stop-arm 2 thus engages with a notch 7 in a ring 8 to stop the type-head in the desired printing position. Movement of a code-disc 1 shifts, by means of a notch 26, an associated spacer-member 27, Figs. 1 and 2, which slides between wedge-members 28 to decrease the overall area occupied by these members and so allow a spring-urged detent 13 to move (downward in Fig. 2). A lug 12 is thus moved out of the path of an extension 10 of the stoparm 2 which is thus allowed to rotate until its roller 5 finds an alignment of notches or, if a non-standard signal is received, until the stoparm extension 10 is arrested by a second lug 11 mounted on the detent 13, in which position of the type-head an " error " symbol is printed. Thereafter the apparatus returns to normal with the type-head in its homing position, i.e. stoparm extension 10 resting against the lug 12. In addition to, or instead of, the type-head the shaft 9 may carry a contact arm of a rotary switch. A modification is described in which the type-head has no homing position and in which a seven-unit code is used and aU character signals have 3 marks. The detent 13a, Fig. 5, carries one lug 11a with a slot 36 through which the stop-arm extension 10 can pass. If a non-standard code signal is received then more or less than three wedge-members 28 will move and the extension 10 will be to one side or the other of the slot 36 and thus arrest the typehead in the error-indicating position.

IPC: C07D473/24
Filed: 1953-09-23
Abstract: Purine derivatives of the formula <FORM:0744865/IV(a)/1> where R1 and R2 are alkyl, mononuclear aryl or mononuclear aralkyl, or form a 6-membered ring with the nitrogen atom, are prepared by (1) contacting with a low temperature Raney nickel catalyst the corresponding compounds having in the 2-position a substituted mercapto group and in the 8-position hydrogen or a free or substituted mercapto group; or (2) ring-closing a 4-amino-5-formamido-6-NR1R2-pyrimidine by heating to 150-300 DEG  C., preferably 200-275 DEG  C.  Process (1) is preferably conducted at 80-110 DEG  C. in aqueous alkaline solution, e.g. 0.1N-2N sodium hydroxide.  Other solvents may however be used instead, e.g. alcohols, glycols, glycol ethers or aromatic hydrocarbons, and the temperature may range from 25 DEG  to 150 DEG  C.  Method (2) may be carried out in the presence or absence of a solvent, in the latter case the pyrimidine being heated at least to fusion point.  Suitable solvents are quinoline, formamide, glycol and diphenyl ether.  The products form salts with strong acids such as hydrochloric, sulphuric, phosphoric and picric.  They also react with bases to give e.g. alkali metal, alkaline earth metal, silver and chloromercury derivatives.  They can be converted into compounds analogous to adenosine.  Examples show the production of the following 6-substituted purines by both methods: 6-dimethylamino, 6-diethylamino and 6 - methylanilino; also of 6 - piperidino-purine and 6-n-butylbenzylamino-purine by method (1).  2 - (Substituted mercapto) - 6 - NR1R2-purines are made as in Specification 744,866 from the appropriately 2:6-di-substituted 4-aminopyrimidines via the 5-nitroso, 5-amino and 5-formylamino derivatives.  2 - (Substituted mercapto) - 6 - NR1R2 - 8-mercapto-purines are prepared as in Specification 744,869 from the corresponding 2:6-disubstituted - 4:5 - diamino - pyrimidines and carbon disulphide.  2:8 - Di - (substituted mercapto) - 6 - NR1R2-purines are made by alkylating the preceding compounds.  An example is given of the production of 2:8-di-(methylmercapto)-6-dimethylaminopurine.  4 - Amino - 5 - formylamino - 6 - NR1R2-pyrimidines are obtained as in Specification 744,868 by elimination of a 2-(substituted mercapto) group.  2 - (Substituted mercapto) - 4 - amino - 6-NR1R2-pyrimidines are described in Specification 744,867.

Abstract: 989,095. Measuring height electrically: A. C. bridges. PLESSEY CO. Ltd. July 27, 1961 (Aug. 2, 1960], No. 26695/60. Headings G1N and G1U. An altimeter for use in an aircraft, particularly for use at landing, is based on the measurement of the capacitance between two horizontally spaced conductors on the aircraft, using the earth as a common coupling electrode, in a Blumlein bridge whose unbalance is used to adjust a second capacitor to maintain the bridge in balance. As shown (Fig. 2), an aircraft carries two horizontal aerials A 1 , A 2  which, with the earth as a common electrode, constitute two capacitors in series whose resultant capacitance is dependent on the height of the aircraft. An oscillator O is connected to this resultant capacitance in series with one winding of a transformer T 1 , coupled to a first winding W 1  on a taroidal core B. The oscillator O is also connected to a parallel circuit comprising parallel variable capacitors C H , C T  and one winding of a transformer T 2 , coupled to a second winding W 2  on core B. The fluxes produced by windings W 1 , W 2  in core B are in opposition, and any resultant flux induces a voltage in a third winding W 3 , which is amplified at D and phase-rectified at F to drive a motor H or J varying capacitor C H  or C T  respectively until the resultant flux in core B is zero. Capacitors C H , C T  vary exponentially so that the displacement of their movable electrode is proportional to height, and is indicated by the slider of a linear potentiometer M also driven by motor H. To maintain the sensitivity of the system constant, the gain of amplifier D is controlled by an exponentially wound potentiometer L also driven by motor H. The aircraft is initially flown at a nominal infinite height with capacitor C H  at its minimum capacitance, and C T  is adjusted by motor J to balance the fluxes in core B. Switch I is then changed over from motor J to motor H, and the subsequent movements of the slides of potentiometer M are calibrated by reference to a predetermined height and zero height. Motor H also drives a techogenerator H 1  whose output is indicative of the rate of climb or descent. The mechanical construction of a complete unit is described.
