Title: Improvements in or relating to the preparation of guanidine salts
Filed: 1947-03-05
Abstract: Guanidine salts are prepared by heating an aqueous solution of an ammonium salt, cyanamide and free ammonia in a closed reaction zone at a temperature above 180 DEG  C., but preferably not higher than 225 DEG  C., for a time less than 20 minutes and preferably less than 10 minutes, the amount of free ammonia present being sufficient to maintain a pH of at least 8 when measured at room temperature, the ammonium salt which is present in the reaction mixture throughout the reaction being in an amount in excess of that required to react with the cyanamide present.  The process is preferably effected by passing the various reactants through a heated reaction zone, as described in the parent Specification, at temperatures above 180 DEG  C. at such rate of flow that the heating period is less than 20 minutes.  In an example, an aqueous solution of cyanamide containing a small amount of dicyandiamide and an aqueous ammoniacal ammonium nitrate solution are pumped through a spiral pipe reaction zone maintained at 200 DEG C. and 250 lbs./sq. inch pressure, there being 1.8 moles. ammonium nitrate per mole cyanamide and the pH being above 8, and the reactants are discharged continuously through a release valve, after a slightly less than 5 minutes heating period, cooled below room temperature, the guanidine nitrate removed by centrifuging and the filtrate concentrated down, mixed with fresh ammonium nitrate and ammonia and reintroduced into the system.

Title: Method of producing coatings from hard high-melting point nitrides
IPC: C23C16/34
Filed: 1955-03-03
Abstract: In a method of coating metallic or non-metallic surfaces with nitrides of metals of the fourth and fifth groups of the periodic system, a halide of the desired metal is caused to react with ammonia in the presence of the surface to be coated at a temperature above the decomposition temperature of the complex compounds formed between the halide and ammonia.  The ammonia and the halide may be introduced separately into the reaction chamber, or the halide may be formed, as by passing hydrogen halide over the nitride of the nitride-forming metal, in the reaction chamber in a zone which has a lower temperature than the deposition zone and the ammonia introduced only into the deposition zone.  The example describes the formation of a titanium nitride coating by reacting titanium tetrachloride with ammonia at a temperature above 650 DEG C. preferably 900 DEG -1200 DEG C., the titanium tetrachloride being introduced in a current of hydrogen.  Reference has been directed by the comptroller to Specification 731,990.

Title: Improvements in machines for transferring cigarettes from a supply hopper into packets
IPC: B65B19/10
Filed: 1926-03-10
Abstract: 260,150. Muller, J. C., and Halank, G. F. March 10, 1926. Packeting cigarettes in containers.-Relates to a machine for transferring cigarettes from a supply hopper into packets, in which the cigarettes are fed from the hopper into a chamber in which they are arranged in rows, and from this chamber by means of a plunger into a packet. According to the invention, the chamber moves in a closed cycle, during which travel a feeler tests the contents, and, if the chamber is insufficiently filled, the chamber is emptied before arrival at the packeting point and the correspond. ing empty packet is prevented from being presented for filling. Cigarettes fall from a hopper 2, Fig. 1, into grooves 4 on a drum 3 which transfers them to a position above a slide 6. The slide is actuated to withdraw and to allow the cigarettes to fall first into one chamber in a channel 12 and then into the other. A slide 14 is then withdrawn to allow the batch to fall into a chamber 21 on a drum 20, the slide 6 being meanwhile returned to the closed position. The chambers are divided by a partition 22, Fig. 5, and the side walls 24 are resiliently held in position by spring-pressed bolts 25. The base 29 is similarly mounted on a bolt 30. The drum is rotated intermittently so that the batch arrives at a position on the left, Fig. 1, arcuate members 23 maintaining the cigarettes in position during transition. A detector, operated by a lever 31, advances so that the projecting arms 40, 41 of feelers 37 contact with the outermost cigarette in each chamber. If the chambers are properly filled the feelers permit the arrival of the batch at a point at which it is thrust into a packet through a guide. If a chamber is not properly filled, the feeler moves to the right and the arm 40 strikes a cross pin 47, Fig. 2, mounted as shown in Figs. 3<b> and 3<c> in a notched spring. The cross-pin is moved from the notch 49 to the notch 49' so that, in the next intermittent rotation, the end coacts with a double-armed lever 52, Figs. 2 and 3. The lever 52 co-operates with a lever 101 pivoted at 102 and having a free end 103 forming an abutment for an arm 104 on the pivot 64 of a rocking arm 62. Upon the lever 101 being moved, the lever 62 is urged by a spring 105 so that an associated slide 63 prevents the feed of a packet corresponding to the improperly filled chamber. At the same time, a flap 77, Fig. 2, in the casing 23 is opened to allow the cigarettes to fall out. In a modification, the feelers are caused to energize an electrical current if the chamber is not properly filled and the cross-pin is moved bv a lever acting in conjunction with an electromagnet.

Abstract: 528,621. Valves. ACROTORQUE CO. April 28, 1939, No. 6735/40. Convention date, Aug. 27, 1938. Divided out of 528,519. [Class 135] A valve device for controlling the supply and exhaust of pressure fluid to and from a pressure actuated apparatus is controlled by the rate of flow past the supply valve and when the rate of flow drops closes the supply valve and opens the exhaust valve. When a hand lever 29 is depressed against the action of a spring 31 the discharge valve 23 controlling communication between the passage 7 and the discharge passage 8 is moved into obturating engagement with a seat carried by the spindle 20 of the supply valve 14. Continued movement of the lever opens the supply valve against the action of a spring 15 to connect the supply passage 6 with the passage 39 and spring-pressed pivoted catch 35 engages a pin 34 to return it in the depressed position. A loosely fitting piston, held against rotation by a pin 81, is arranged in the passage-way between the supply valve and the passage 7 so that the flow of fluid past the piston moves it against a spring causing a spring-pressed pawl in the piston-rod to snap over a tail in the catch 35. When the flow decreases the catch is released and the supply valve closed and the discharge valve opened.

Filed: 1917-01-11
Abstract: 112,574. Hayter, W. H. Jan. 11, 1917. Cams; levers; levers, locking.-A cam lever A of the kind which in operation exerts pressure at two points of the cam surface, one on each side of the fulcrum so as to be self-locking, is mounted by means of a slot a<1> and pivot b, so that when being forced to the pressing position, the pressure at the rear portion or heel a<3> of the cam causes the lever to move endways so as to keep the front portion or toe a<4> of the cam also in action. Fig. 2 shows the lever mounted in a slot c in a hollow stud or tie c so as to fasten together three members d, e, f. In order to insert the stud, the lever is turned to the position shown in dotted lines, and in order to give a preliminary pressure it may be turned further back to bring the part a<5> of the cam against the edge of the hole c<1> in the member e. Instead of both heel and toe bearing upon the edge of the hole e<1>, either of them may bear upon an abutment on the stud such as the bottom of the slot c. The slot a<1> may be somewhat inclined and also open at one end and may be formed in the stud instead of in the cam. The arm of the lever may be detachable to prevent unauthorised operation. If a single throw of the cam lever is insufficient to produce the required pressure, e.g. when used for compressing a bale of soft goods, further pressure in stages can be obtained by swinging the lever back to the dotted line position threading washers over it, and again pressing it home, or a number of cam levers of different throws may be mounted on the pivot as shown in Fig. 7 and operated successively, and a catch a' may be provided to lock the levers together in the pressing position.. Specification 107,987, [Class 144 (i), Wheels &c.], is referred to.
