Title: Method of and apparatus for tying packages and the like with non-metallic tying means
IPC: B65B13/26
Filed: 1965-10-29
Abstract: 1,089,065. Bundling-machines. W. BORN. Oct. 29, 1965 [Nov. 3, 1964], No. 45953/65. Heading B8C. (Also in Division D1). Apparatus for securing a package P with a cord and tying a weaver's knot comprises a table top 2, Fig. 1, having slot 3 and supporting an arcuate arm 6 rotatably mounted to pass into the slot when a package has been slid on the top and in so doing engages the end extending from the end of the arm to a clamp 22 beneath the top. The movement of the package on the top actuates a switch 9, Fig. 2, which initiates operation of the apparatus. The package having then slid on the table against the cord 5 causes the cord to extend from the clamp 22 over a notch 18a in stationary plate 18 and also over a hook 23, Fig. 4. The hook 23 is then caused to rise, move sideways and then below the plate 18 when simultaneously a hook member 30 seizes the cord portion 53 and draws it downwardly as illustrated in Fig. 5, so that an inverted U, S3, S4, S7, is formed in the cord. The arm 6 is thereupon swung to pass beneath the inverted U portion of the cord and engage its yarn in the clamp 22, Fig. 6, the cord portion initially held by the clamp 22 having been released and now secured by the hook member 30 clamping it against the body portion 31 in which it slides. A member 33a, Fig. 6, is then advanced and engages behind the arms S3, S7 of the cord whereupon it is moved sideways to deflect the inverted U loop of the cord off the rose 18b of the plate 18 on to a hook 36 which was advanced into position with the member 33a. The further sideways movement draws the loop sideways, Fig. 7, and draws the cord secured around the package taut. A gripper 47 is then advanced beneath the arms of the loop and grips the cord portion S5, Fig. 7, and draws it back beneath the arm of the loop and subsequently sideways whereby it is caused to pass over the member 33a into a slot 33b therein in which it is retained by a loop wire 39, Figs. 8 and 9, the cord portion S5 having previously been severed by a blade 41 drawing it on to a cutter 55. A clamp 58 is then advanced to engage the end portion S3 and is withdrawn as the member 33a is withdrawn so that a loop portion S8, Figs. 10 and 11, is drawn to complete the knot and the knot finally tightened. A cutter in the clamp 58 then cuts the end to release the package or the clamp 30 is raised to release the end of the cord. The various components are actuated by electric valves such as 15, Fig. 2, operating pneumatic or hydraulic piston-and-cylinder units 16A ... 16N coupled to the knot forming mechanism and clamps.

Abstract: 1378377 Valves HYDRAULIC INDUSTRIES Inc 20 Jan 1972 [20 Jan 1971] 49147/71 Heading F2V A control valve 10, Figs. 1 and 2, comprises a body 20 with a bore 24 and an elongated spool 25 slidable therein to connect a supply passage 27<SP>1</SP> with a service passage 29, a passage 59 opening at a zone 50 into the bore between the supply and service passages, passageways 44, 36, 46 in the spool to connect the supply passage 27<SP>1</SP> to the service passage and the zone 50 from which passages 59, 58, 60, Fig. 3, apply pressure to a compensating valve 62, Fig. 4. In the preferred embodiment, a single pressure actuated compensating valve in a housing 14 supplies a stack of control valves 11, 12, 13 each providing independent control of either a single or double acting motor. When a double acting motor is to be controlled, a pair of service ports 29, 30 are controlled by the spool so that one is connected to the supply passage 27<SP>1</SP> when the other is connected to one of a pair of exhaust passages 31, 32. A common outlet 18 communicates with all of the exhaust passages and receives fluid direct from the inlet 17 through bores 69, 70 when all of the control valves are in neutral and the valve 62 is held open against a spring 67 by inlet pressure applied through a port 72 to a bore 74. Opening of one of the control valves causes an increase in pressure in one of the zones 50, and through a non-return valve 61 and the passage 60, an increase in pressure on the left hand end of the valve 62. Direct flow from inlet 17 to outlet 18 is thus throttled and the speed of the motor being supplied is kept uniform by the pressure drop across an orifice upstream of a check valve 78, Fig. 4a, in the passage 60. The pressure imposed on the left hand end of the valve 62 is limited by a valve 85. The speed of the motors may alternatively be controlled by the pressure drop across one or more washers (80, Fig. 1a) inserted between the control valve sections. In further modifications, the non-return valves 61 in each control valve section are replaced by a single non-return (161, Figs. 3a, 3b) between each pair of zones 50 and the passage 60, the valve 62 is provided at its left hand end with a spring-loaded plunger (92, Fig. 5) so that it opens rapidly in response to a sudden increase in inlet pressure or is provided with a land (108, Fig. 7) to connect the inlet to a by-pass port (130) which may lead to a further control valve (131, Fig. 7b) or be closed by a plug (135, Fig. 7b) to convert the control valves to closed centre operation, the spool in each control valve is provided with a series of holes (98, 99, Fig. 6) corresponding to different speeds of operation of the motor being controlled or is designed so that on movement to an operative position the inlet 17 supplies only one service port or is disconnected from the control valves downstream from the valve operated.

Abstract: 1,148,513. Synthesis of ammonia. CHIMKOMBINAT. 2 Nov., 1966, No. 49227/66. Heading C1A. [Also in Division B1] Ammonia is synthesized by reacting nitrogen and hydrogen in a reaction zone in the presence of a particulate catalyst wherein the catalyst is magnetic and in a fluidized state and wherein the catalyst is under the effect of an applied magnetic field, preferably created by an electromagnet, of which the field strength is such that the particulate catalyst is not carried out of the reaction zone by the flow of gas maintaining the catalyst in a fluidized state. Preferably the reaction is carried out above atmospheric pressure, with a volume hourly space velocity of the nitrogen-hydrogen mixture of over 10,000h<SP>-1</SP>, using a catalyst whose particle diameter does not exceed 4 mm. The reaction temperature may be from 50 to 125 C. lower than the optimum temperature for a stationary layer catalyst. The reaction may be carried out in the apparatus shown in Fig. 1 wherein the gas-synthesis mixture enters the upper part of the apparatus, passes down between the cylinder 1 and heat exchanger 2 and enters the lower part of the heat exchanger 8. The heated gas then passes upwardly through the heater 6, downwardly through the tubes 3, thus entering the lower portion of the catalyst zone wherein reaction takes place. The flow of gas mixture and the applied magnetic field fluidize the catalyst but the catalyst is contained with the reaction zone by the applied magnetic field generated by the magnets 4.
