Patent GB-1122606-A (GB)
Title: Safety closure for containers
IPC: B65D50/04
Filed: 1966-12-02
Abstract: 1,122,606. Caps for bott'es. ART ON INDUSTRIES Inc. 2 Doc., 1966 [2 Dec., 1965], No. 54120/66. Heading B8T. A tamper-proof screw cap 5, Fig. 1, for a plastics bottle, &c. 1 comprises an internally threaded closure member 9 carrying rotatably an intermediate sleeve 10 (see also Fig. 6), on which is rotatable and axially slidable an outer operating knob 17 (see also Fig. 7), with clutch dogs, &c. 25-27 interengageable so that the knob can be turned to unscrew the closure. Lifting the knob 17 to the Fig. 1 position causes lip edge surfaces 23 at the bottom of the knob to slide over cams 33 on the intermediate sleeve 10, which is accordingly turned on the closure 9 to misalign the clutch recesses 25, 26 and prevent re-engagement of the clutch dogs, &c. Thus unscrewing of the bottle cap is prevented until the intermediate sleeve 10 has been turned back to re-align the clutch recesses 25, 26 when the knob 16 can be simultaneously pushed down and rotated to slide the clutch dogs 27 again into the recesses. Re-alignment of the clutch dogs, &c. 25-27 is facilitated by index marks (28, 30), Fig. 2 (not shown), on the enclosure 9 and knob 17, and a view hole (29) through the intermediate sleeve, the knob and sleeve being turned till all three are vertically above each other.

Title: Electric discharge machining apparatus
IPC: B23H1/02
Filed: 1967-11-28
Abstract: 1,213,648. Electro-erosion. SILTRONICS Inc. 28 Nov., 1967 [19 Dec., 1966], No. 54196/67. Heading B3V. [Also in Divisions H3-H5] An electro-erosion machine includes a capacitance means 20<SP>1</SP>, Fig. 4, charged from a unidirectional potential source 28<SP>1</SP> through a slower charging element 24<SP>1</SP> or a faster charging element 26<SP>1</SP>, the latter of which is connected in circuit by a switching means 58<SP>1</SP> when the gap has deionized sufficiently following each discharge thereacross to permit a faster capacitance charging rate. Input signals are applied through a low pass filter 76 to the base of a transistor 72 of a keying circuit 62<SP>1</SP> and as biases to the emitters of transistors 70, 72. At low gap voltages the collector of transistor 72 and the base of transistor 70 assume the potential of the source 28<SP>1</SP> to turn on the transistor 70, the low negative potential of the collector of which is applied to the base of the transistor 581 which is biased to cut-off. The capacitance 20<SP>1</SP> is thereby slowly charged through the resistance 24<SP>1</SP>. When the gap has deionized to about 20 volts, the base potential of the transistor 70 is decreased by the transistor 72 causing the transistor 70 to be cut off and the main supply potential 28<SP>1</SP> to be applied to the transistor base 58<SP>1</SP> so that the faster charging resistance 26<SP>1</SP> is brought into circuit. The transistor 58<SP>1</SP> is biased to cut off when the gap voltage has fallen again to about 20 volts. In another embodiment, Fig. 8, the spark cutting time is increased by a pulse prolonging circuit 90<SP>1</SP> which delays the reopening of the transistor 58<SP>1</SP>. Upon cessation of the keying circuit 62<SP>1</SP> pulses, a monostable multivibrator circuit 104 continues to deliver a voltage on an output conductor 106 to the base of the transistor 58<SP>1</SP> to maintain it closed. The multivibrator circuit 104 is then returned automatically to its stable condition. The unstable interval is adjustable by a variable resistance 110. In a further embodiment, Fig. 10, during the slow charging of the capacitance 20<SP>1</SP> the circuit includes a resistance 146 plus the resistance of a transistor 140 which is switched partly on by a voltage source 148 and resistance 150. When the transistor 140 is switched full on by the keying circuit 621 it offers little resistance so that the charging rate of the capacitance 20<SP>1</SP> is greater. The resistance 146 can be omitted and the amplitude of the keying circuit output pulses reduced by a resistance 152. The switch 58<SP>1</SP> may be a transistor, silicon controlled rectifier, thyratron or mercury arc device.

Abstract: 1,190,108. Dispensing sensitivity discs into Petri dishes &c. BECTON, DICKINSON & CO. Nov.29, 1967 [Feb. 16, 1967], No. 54334/67. Heading C6F. Sensitivity discs used in the laboratory study of microbiological cultures, growths and specimens, are ejected simultaneously from a battery of some 8 or 12 cartridges 48, Figs. 3 and 4, by the manual depression of a plunger 25 and the ejected discs descend down corresponding guideways 32 to settle within a Petri dish 55 in an accurate pattern and location e.g. with their centres at least 24 mm. apart. The depression of the plunger is translated through the angle member 27 into a limited horizontal (left-to-right) displacement of a dispensing plate 36 within the confines of rectangular recesses in the stationary plates 28 and 31. Fingers 50 Figs. 5 to 7 (not shown) on the dispensing plate eject the disc sideways from its cartridge into the adjacent guideway. The opening in the guideways tapers slightly inwardly from top to bottom and the axes are flared outwardly. The cartridges are secured by their bridges, which fit into recesses in the plate 31, and by a lock plate 41 actuated by a thumb lock 44. The distance between the guideways and the Petri dish 55 is preset to between 1À5 and 3 mm. (the sensitivity discs have a tendency to float when dropped from too great a height) by rotation of a knurled ring 35 along a measured thread on extension piece 34. Three equally spaced radial ribs 51a extending between the annular shoulders 51 and 52 of the ring engage the rim of the Petri dish. Vessels of other sizes are accommodated by inverting the ring to present its flat surface. In an alternative embodiment Figs. 10 to 12 (not shown) the guideways and means for adjustment just described are fixed by screws to a conventional, lever-actuated disc dispenser.
