Title: Adhesive tape dispensing machine
IPC: B65B67/06
Filed: 1960-06-08
Abstract: 950,939. Packaging-machine; applying identification tape. MINNESOTA MINING & MANUFACTURING CO. June 8, 1960 [June 8, 1959], No. 20158/60. Headings B8C and B8F. A device for placing a strip of adhesive tape round the neck of a filled bag or round a bundle of articles, includes a recess spanned by the tape and into which the bag neck &c. is introduced to be partially surrounded by the tape, and a shuttle member for passing the tape across the unenclosed side of the neck and causing it to adhere to the tape free end. In one embodiment, spaced plates 50, 51 are pivoted to a base 52 at 54 and carry a tape roll 80. Tape from the roll passes over the shuttle 60 and across the recess 65. The shuttle is pivoted between the plates at 58 and is connected by a link 70 to the base. A spring 63 retains the shuttle retracted and the plates 50, 51 in an upper position. A roller 84 capable only of anti-clockwise movement as shown, presses the tape against the shuttle. A knife 67 is mounted between the plates. In operation, the bag neck &c. is pressed against the tape (adhesive side uppermost) in the recess and thereby depresses the plates. The link 70 causes the shuttle 60 to pivot forwards, taking the tape round the neck, pressing together overlapping portions to form a " flag," and severing it between the knife 67 and a recess 62. A member 77 fixed on the link 70 draws further tape off the reel. The bag is withdrawn upwards enabling the plates and shuttle to return to the position shown, the tape spanning the recess being raised during withdrawal and falling back ready for the next operation. In another embodiment (Figs. 1, 3, not shown), the shuttle is slidable in rectilinear grooves in the plates and a spring plate holds the tape against retraction. In a further version (Figs. 8-11, not shown) the knife is slidably mounted on the shuttle and linkage moves the roll tc draw off tape. An interchangeable insert at the base of the recess enables various sized necks &c. to be tied.

Title: Improvements in apparatus for chlorinating water or other liquid
IPC: C02F1/76
Filed: 1921-07-28
Abstract: 188,045. Paterson, W. July 28, 1921. Purifying liquids.- In apparatus for sterilizing or purifying water or other liquid by treatment w i t h chlorine of the type in which the flow of chlorine is measured by taking the difference in the pressures on opposite side of a restricted orifice, a seal of liquid not affecting or affected by the chlorine is provided between the chlorine control apparatus and the liquid to be treated. The Figure shows a glass vessel mounted between a shield b and a cover c and containing sulphuric acid. A central tubular vessel h is connected to the supply pipe for the chlorine, which after passing through the seal is led through an outlet k to the liquid to be treated. There are apertures i in the vessel h, so that, should the acid rise in the vessel h on account of a fall in temperature, such rise cannot continue beyond the point at which the acid outside the vessel h has fallen to the level of the apertures. Specifications 158,578 and 166,191 are referred to.

Barometers.-Errors in altimeters and barometers of the aneroid type due to the arrangement and disposition of the masses of the various elements in the mechanism are reduced by balancing. The capsules 2 have on one side central bosses attached to the main support 1 of the instrument, and on the other side adjustable knife edges 4 engaged by the main spring 3 which exerts force along the axis of the capsules. One limb of the spring carries an adjustable arm 8 and the other limb a bracket 7 on the free end of which is pivoted a spindle having a short adjustable arm forming with a fast long 'arm 11 a bell crank. The short arm 10 is connected by a link 12 and zigzag bimetallic strip 13 with the lever 8, while the end of the arm 11 has attached to it a chain 14 the other end of which is wrapped around and secured to a drum 15 on the pointer spindle 16. A light spring 20 attached to the spindle and to a cock-piece 17 takes up back-lash. The cock-piece is secured to a strip 18 made fast to the main support 1 as is a similar strip 19 opposite the strip 18. These parts 18, 19 serve as stops for limiting the movement of the capsules. The weight of the parts is so disposed that balance is secured about the axes 6, 6 and 21, the support being at the centre of gravity.

The target plasma is created by ionization and heating of an electrostatically-suspended pellet and is magnetically confined. A laser or electron beam may be used to activate the pellet. Injection of the neutral beam results in heating of the plasma by charge exchange and ionization. At this time the constituents of the initial plasma may be replaced. The pellet may comprise lithium deuteride, lithium hydride, cooled deuterium or tritium, or suitable mixtures thereof. The mirror magnetic confinement field may be produced by a Saddle-form winding (Fig. 3, not shown). It may be a superconductor or resistance winding. The field may vary with time but preferably is constant. Ions leaving the plasma are pumped by a cooled gettering surface. The injected beam may comprise neutral deuterium and tritium. A variety of confinement field configurations may be used including spherator, stellarator or tokamak types.

Title: Voltage regulator
IPC: H02P9/30
Filed: 1962-06-04
Abstract: 935,469. Automatic voltage control. FAIRBANKS, MORSE & CO. June 4, 1962 [July 13, 1961], No. 21527/62. Class 38 (4). In a voltage regulator for an alternator 2 having a field winding 6, a signal indicative of the output voltage is derived from a circuit including a transformer 14, a rectifier bridge 18, a smoothing capacitor 24 and a voltage divider 26, 28 and is applied over a Zener diode 36 to the base of a first transistor 30 controlling a second transistor 40 in series with the field winding 6. When the output voltage rises above a preselected value, determined by the breakdown voltage of the Zener diode 36, current flows through the diode 36 and renders transistor 30 conductive, whereby transistor 40 is cut-off so that the field excitation and the output voltage decrease. When the output voltage is below the preselected value, diode 36 and transistor 30 are non-conductive; transistor 40 becomes conductive by virtue of base current drawn through a resistor 32 and allows field current to flow. A pulse transformer 48 having its primary winding 46 in series with the emitter/collector circuit of transistor 40 and its secondary winding 50 in series with the voltage divider 26, 28 helps to accelerate the switching of diode 36 from conduction to non-conduction.
