Abstract: 1481378 Making self-standing bags DAI NIPPON INSATSU KK 1 Aug 1975 [25 Dec 1974] 32205/75 Heading B5D [Also in Division B8] Self-standing bags, Fig. 4, are produced from a web S, Fig.14A, having a heat-fusible coating. The web S is advanced stepwise by feed rollers 64, Fig. 14B, over guide rollers 32, 33, 34, Fig. 14A, to a plate 35 where it is folded along its centre line 36 with the heat-fusible coating inwards. The folded web passes between pressing rollers 37 and while it is stationary a punch 38 forms notches 42 adjacent the line 36 and equally spaced along the web. The web then passes outside guide plates 45a and against a cam plate 45b which cause the fold line 36 to be reversed, and additional parallel fold lines 47 to be formed so that the web now has a W-shaped cross-section. The two strips of a closure 20 may be fed between the two web walls at this stage. Heated damping plates 51a, 51b then seal the lower edges of the side walls to the edges of the base wall, as at 15, Fig. 4, and a heated bar 58 seals the closure strips 20 to the walls if necessary. Cooling plates 56a, 56b, 59 cool the seals after a further advance of the web. Transverse seals are formed over the notches 42 by heated plates 60a, 60b and cooled by plates 61a, 61b, and the transverse seals are severed centrally by knives 65a, 65b.

Abstract: 246,776. Marks, E. C. R., (Morkrum Co.). July 30, 1924. Synchronism indicators; distributor systems.-Relates to means for indicating any divergence from synchronism of the distributors at two connected stations. 'The corrected distributor is associated with two electric indicators, such as the lamps S, F, Fig. 1, which by the joint action of two means respectively controlled by line impulses and by the corrected distributor, and respectively controlling the circuits of the indicators simultaneously and in alternation, are displayed similarly when the distributors are running in synchronism, and differently in one way or in another way according as the speed of the corrected or the correcting distributor is the greater. The received impulses operate the printer relay PR through the line relay LR to connect a battery 2 to a conductor 3 or a conductor 4 according to the polarity of each impulse. The conductor 3 is connected to distributor contacts 5, and the conductor 4 is connected through a switch 6 to distributor contacts 7 alternating with the contacts 5. A brush 8 connects the contacts 5 and 7 with contacts 9, 9<1> connected to the selecting magnets of the printers and with contacts 11, 12 arranged as shown and connected to earth through leads 13, 15 and the lamps S, F respectively. To obtain an indication of the relative speeds of the distributors, the transmitting distributor is allowed to run idle, thus sending impulses of opposite polarity alternately to line, and the switch 6 is opened. If the distributors are in exact synchronism both lamps are lighted simultaneously. If they are not in synchronism lamp F will be extinguished before lamp S or vice versa according as the speed of the transmitting or receiving distributar is the greater.

Oct. 31, 1930, No. 32774. Convention date, Nov. 1, 1929. [Class 122 (iv).] Where, as in a ship propulsion system, a number of prime-mover-driven generators supply a number of motors and means are provided for changing the connections between the generators and motors, the control means which effects the change is connected with means whereby the speed of the prime movers may be limited when connections are such as might otherwise cause an overload of a generator or a motor. As shown in the Figure, switches 29 connect each generator 5, 6 to a motor 3, 4 and a mechanical linkage connects the switches with members 53. When the connections are changed so that both motors are connected to a single generator, with a possibility of overloading the generator, stops 54, 55 are thereby placed in the path of speed-regulating levers 11, 12 to limit the maximum speed of the prime movers. In an alternative arrangement, where switches are provided so to change the connections that two generators may be connected to a single motor, with a possibility of overloading the motor, similar means are provided to limit the prime mover speed. The speed governing means illustrated is described in Specification 3026/12, [Class 57, Governors. &c.], which is referred to.

Abstract: 786,643. Sawtooth generator circuits. CINEMA-TELEVISION, Ltd. Nov. 16, 1955 [Nov. 16, 1954], No. 33155/54. Class 40 (6). A signal generator for producing a sawtooth waveform balanced about a mean potential in response to a control pulse comprises a first pulse generator which generates an output pulse of predetermined duration in response to the control signal and a second pulse generator triggered by the cessation of the pulse generated by the first pulse generator to produce a second pulse of predetermined duration, thus in response to pulses from the first generator the charge in a capacitor is altered at one rate and a second generator prevents the charge in the capacitor from being altered in the same sense at another rate, the charge in the capacitor being changed in the opposite sense continuously. Fig. 3 shows a sawtooth generator in which the flip-flop circuit comprising cathodecoupled valves 11, 12 is triggered by a negative pulse applied at input 10 to generate a negative output pulse of predetermined duration at the anode of tube 12. This pulse is applied to the control grid of tube 18 to cut it off, so that its cathode goes negative until it reaches a voltage lower than that at which capacitor 42 is clamped by tube 21, diode 20 thus conducts and the portion AB of the waveform shown in Fig. 2 is generated. When the pulse on the grid of tube 18 ends diode 20 is cut off. The positive-going voltage at the anode of tube 12 triggers a second cathode-coupled flip-flop circuit comprising tubes 14, 15 to generate a positive pulse at the anode of tube 15 this causes tube 17 to conduct, its cathode going positive so that diode 19 is cut off. The potential on capacitor 42 rises due to current flowing into it through resistors 43, 44, thus generating the main stroke BC of the sawtooth waveform shown in Fig. 2. At the end of the second pulse valve 17 is cut off so that diode 19 passes current and capacitor 42 discharges until diode 21 conducts and clamps the voltage across capacitor 42, thus generating portion CD of the waveform shown in Fig. 2. The potential across capacitor 42 is applied to the grid of tube 22 which is connected in a " boot-strap " circuit, the voltage at its cathode being applied back to charging resistor 43 so that the charging rate remains constant. Non- linearity of the discharge is reduced by returning discharging resistors 40 and 45 to the junction of suitably chosen resistors 48, 49 in the cathode of tube 22. The circuit may be modified, Fig. 5, not shown, to generate the inverse sawtooth waveform as shown in Fig. 4.

Class 143 [Also in Group XXX] Glass bottles 2 in transit from a forming machine 1 to an annealing bar 4 on a conveyer belt 3 are periodically transferred from the stream onto a dead plate 16 by a swinging arm 10 cooperating with a second swinging arm 17, are then moved on to a weighing plate 23 by a reciprocating pusher 24 and finally, after a weight indication or record has been made, are moved back onto the conveyer by a pusher 20; the invention being characterized in that the frequency of operation of the mechanism is adjustable and that the means for initiating the displacement of a selected bottle from the conveyer onto the plate 16, and the replacement of the previously selected weighed bottle onto the conveyer, does not obstruct the passage of articles along the conveyer and is ineffective during a weighing operation. The cycle of operations is triggered by the engagement of a bottle with an arm 6 which, when so engaged, trips a mercury switch 7 which in turn releases a single revolution clutch (not shown) and so rotates a series of cams (also not shown) which effects the testing cycle; the frequency of operation being controlled by varying the speed of rotation of the cam driving shaft and/or by providing a commutator which is adjustable to cause the clutch circuit to be energized after a predetermined number ot actuations ot the arm to permit the transfer of a weighed bottle onto the conveyer in the space vacated by the next article to be weighed. The weight of the bottle under test is transmitted by an electronic repeater, similar to that described in Specification 589,423, [Group XXXVIII], to an indicating or registering mechanism, a cam being provided to isolate the transmitter during movement of bottles on and off the plate 23. During the testing cycle the arm 6 is tripped by succeeding bottles but this does not effect the cycle. The whole of the testing mechanism is supported by a wheeled truck 5 and the height of the operative parts is adjustable to adapt the apparatus for use with different conveyers. In a modification the arm 6 may be replaced by a photo-cell and light beam or by a series of rotary arms. Specification 368,335 also is referred to.
