Filed: 1964-02-21
Abstract: 993,832. Reclosable dispensing carton. AMERICAN CAN CO. Feb. 21, 1964, No. 7284/64. Heading B8P. A dispensing carton with a reclosable pouring spout, made from a single paperboard blank A, is folded to tubular form and secured by a glue flap 54. To erect the carton, the shell is squared to a boxlike shape and the bottom end is sealed in the conventional manner. The top is closed by covering the outer faces of dust flaps 55 and 58 with adhesive and folding them inwardly about score lines 14, 25. An end closure flap 57 which is unfolded about score line 15 adheres to flaps 55, 58. Similarly adhesive is applied to an end closure flap 59 which is folded about score line 19 to adhere to flap 57. This sealing may be effected by putting the collapsed shell over a mandrel. Pressure causing a tear action along perforation lines 34, 36 and 38, 40 enables portions 51b, 53b, 57b, 58, 59b and 60a to be removed by detachment along perforation lines 33, 37, 41 and the contents may be dispensed.

Patent GB-1180495-A (GB)
Title: Improvements in or relating to On-Off Control of SCR Regulated Power Supply
IPC: H02M7/162
Filed: 1968-02-14
Abstract: 1,180,495. Control systems for D.C. motors. ELECTRIC REGULATOR CORP. 14 Feb., 1968 [7 March, 1967], No. 7336/68. Heading H2J. [Also in Division G3] In an electrical supply system of the type comprising a power regulator feeding a load through a main ON/OFF switch, this switch is closed and opened at substantially zero current by a start/stop circuit controlling the switch and the regulator in such a manner that at the start of a supply period the switch is closed with the regulator in a reduced output condition, after which the output is increased to the desired value, and at the end of the supply period the regulator output is reduced before the switch is opened. The described embodiment relates to a constant voltage supply 8, 10 for a compound excited D.C. motor M provided by rectification of a three phase A.C. supply 2, 4, 6 through a bridge circuit including controlled rectifiers 26, 28, 30 whose firing angles are determined by magnetic amplifiers 50, 52, 54 having control windings 50c, 52c, 54c connected in a comparator circuit 98. The start-stop control circuit (Fig. 2) comprises a sequential switch having a first electromagnetic winding 136 controlling the main ON/OFF switch 24 and a second electromagnetic winding 144 controlling switches 44a, 46a, 48a, 120, 146, the first three of which (normally closed) control the firing circuits of rectifiers 26, 28, 30, the fourth (normally closed) controls the reference voltage part of the comparator 98 and the fifth (normally open) acts as a hold-on switch for the start button switch 122. Closure of the latter switch energizes windings 136, 144 but a time delay provided between their actions causes the switch 24 to close first at zero output of the regulator produced by the disabling actions of the switches 44a, 46a, 48a, 120. Thereafter switches 44a, 46a, 48a open to allow energization of the firing circuits, followed by opening of the switch 120 which causes the output of the regulator to be gradually increased to its preset value due to the delay action of a capacitor 116 which prevents the reference voltage from immediately attaining its preset value. Actuation of a stop switch 124 deenergizes the winding 144, but winding 136 remains temporarily energized through the switch 146 to maintain the switch 24 closed. De-energization of winding 144 causes switch 120 to close first and gradually reduce the regulator output to zero, followed by closure of the switches 44a, 46a, 48a to disable the firing circuits and finally by opening of switch 146 to de-energize the winding 136 and open the switch 24. The switches 44a, 46a, 48a also prevent spurious firing of the rectifiers by transients.

Title: Improvements in or relating to cable motor ploughs and the like
IPC: A01B3/68
Filed: 1940-04-25
Abstract: 541,482. Cable motor ploughs. DANIEL, A. April 25, 1940, No. 7441. [Classes 6 (i) and 45] [Also in Groups XXVIII and XXX] The cable drum comprises a hollow wooden cylinder without axle, with metal rims which are supported by grooved wheels carried by a frame. The drum carriage 14 is arranged at one side of a field and a horizontal anchored pulley at the other side. Ploughing is effected as the ploughs are drawn towards the drum, the return movement being made at a greater speed out of contact with the soil, and by a lighter cable. The drum carriage is secured in successive positions by the engagement of projecting hooks 21 with a cable or chain 22 anchored by a chain 23. Drums 26, 27 for the heavier and lighter cables are mounted coaxially below a motor 28 which drives them through gearing 29, 30, sliding pinions 32, 33, and toothed wheels 34, 35 formed on the drums. Each drum consists of a hollow cylinder of bent wood carrying flat metal rings 37, 38 connected by bars 39. The drums are retained in position by the engagement of the rings 37, 38 with grooved wheels 41 on a common axle 42 carried by a frame 43 secured to the base 44 of the drum carriage. The carriage is mounted on three wheels 15; 16, 17, two of which, 15, 17, may be adjusted vertically simultaneously by screwed shafts 47, 49 connected by bevel gearing and a link 50. A clutch 51 permits the shaft 49 to be disengaged. Fig. 5 shows the control for the winding mechanism. A vertical tube 52 mounted adjacent to the winding drum is threaded at 53, 55, and carries a non-rotatable nut 56 which moves slowly vertically to guide the cable 19 on to the drum. The central part of the tube 52 carries a pinion 59 rotating with it but capable of relative vertical movement. Two spindles 60, 61 carrying pinions 62, 63, are rotated in opposite directions by gearing from the drum, and are selectively engaged by the pinion 59 by an automatic control, the direction of rotation of the tube 52 depending upon which pinion is engaged. A nut 70 which is prevented from turning, is engaged by the upper end of the tube, and both nuts 56, 70 move in the same direction. Assuming that both are moving upward, the spring 71 becomes compressed, the pinion 59 being held against axial movement by a detent lever 73 pivoted at 80, until the upper end of the lever is moved inward by the nut 70, when the pinion is suddenly released and moved upward by the spring 71 to engage the driving pinion 63, and is retained in that position by another detent 74. The direction of rotation of the tube 52 changes, and both nuts move downward. This continues until the nut 56 engages detent lever 77 and releases pinion 59 for another reversal. Friction of the springs on pinion 59 is prevented by rollers 76. The drum carriage is anchored while ploughing by passing the chain or cable 22 around pegs 81, preferably of T-section, driven into the ground, and carrying sheaves 82.
