Title: Two-part safety closures
IPC: B65D39/08
Filed: 1973-06-04
Abstract: 1432252 Safety closures CONTINENTAL CAN CO Inc 4 June 1973 [6 June 1972 16 Oct 1972] 26520/73 Heading B8T A safety closure has a cylindrical sleeve 12 which snaps telescopically onto the dispensing element 13 of a container, and a cap 11 which screws on to the sleeve 12 and is characterized by the sleeve 12 being free to rotate on the dispensing element 13 and therefore requiring to be gripped while the cap 11 is unscrewed. The cap 11 has an interrupted rolled rim 17 which allows it to be secured to the plastics sleeve 12 by mating with threads 26 by relative axial movement followed by rotation. The sleeve 12 has a tapered bore 23 with a diameter at a plane L2 equal to the outside diameter of a dispensing element bead 39 so that the assembled cap 11 and the sleeve 12 can be telescoped into position on the dispensing element 13, utilizing the radial resilience of the sleeve 12 above the plane L2, the sleeve 12 then being free to rotate but not to move axially. Arising from friction between the rolled edge 17 of the cap 11 and threads 26, assisted by stops 30 and protrusions 60 and 61 rotation of the cap 11 will cause similar rotation of the sleeve 12 unless the serrated rim 33 of the sleeve 12 is gripped. Sealing material 18 or a paper liner within the cap 11 provides a seal on to the container at 41 and 39A. Other embodiments show (a) Fig. 6 (not shown) a sleeve 12 with an internal groove 45 in its upper part which locates on to a bead 39 on the container neck, with or without contact between the container and the lower end of the sleeve 12, and with sealing contact between the cap 11 and both the container rim and the sleeve rim, (b) Fig. 5 (not shown) a container neck which includes a perforated diaphragm 47 and (c) Fig. 7 (not shown) the addition of sawtooth projections 51 to the rim of the sleeve 12 so as to press into the sealing material 18 and increase the friction between the cap 11 and the sleeve 12 particularly in the unscrewing direction.

Title: Improvements in or relating to electric timing apparatus
IPC: H03K17/288
Filed: 1952-10-23
Abstract: 741,939. Valve relay circuits. EXPRESS LIFT CO., Ltd., and YEOMANS, K. A. Oct. 23, 1953 [Oct. 23, 1952], No. 26646/52. Class 40 (6). A timing circuit comprises a relay having a first winding through which a direct current is passed to neutralize the residual magnetism of the relay and a second winding in the anode current path of a normally conducting valve, the timed interval being initiated by connecting the H.T. to the valve whereupon a capacitor in the grid circuit charges or discharges until the anode current is reduced to such a valve that the relay releases. On switching on the H.T. supply to the circuit shown, the relay operates due to the current through winding 16, the current through the second winding 18 being sufficient only to partly neutralize the residual magnetism of the relay. A capacitor 12 between the grid and cathode of the valve charges at first partly through the grid cathode path of the valve and then solely through resistor 13. The grid voltage accordingly slowly falls and when the anode current has decreased sufficiently, the relay releases. The circuit is restored by interrupting the H.T. and, if necessary, discharging the capacitor through a resistor 24. The delay can be varied by adjusting potentiometer 15, capacitor 12 or the current through winding 18. Preferably the relay is such that when both windings are disconnected, it remains operated.

Abstract: 1,111,353. Circuits employing bi-stable magrietic elements. SIEMENS A.G. 21 June, 1966 [22 June, 1965], No. 27571/66. Heading H3B. Pairs of column or row conductors of a random access storage matrix are connected together in parallel. In a multi-planar matrix the row conductor pairs of adjacent planes are connected in series (Fig. 2) and corresponding column conductors in each plane are connected to a common source. Magnetic cores in the rows of a pair are differently orientated so that, for a particular direction of current flow in a column conductor and a pair of row conductors, the fluxes induced add in one core but not in the other. In this arrangement the particular core is selected by choice of the direction of the row current, whereas in Fig. 1 (not shown), the column current is reversed to select the core. Switches S1 S2 determine whether a " 1 " or a " 0 " is stored. For read-out the column current is reversed and the appropriate row current is supplied. The signals induced on the lines of a pair of row conductors affect a transformer core differentially to generate an output on line L1, L2. In Fig. 3 (not shown), the column conductors are connected in pairs and the row conductors are not The first and third column conductors of a plane are connected, by way of diodes, to one transformer winding and the second and fourth to the other winding. In this case a single transformer suffices for each matrix plane. All the column conductors of a plane are also connected by way of rectifiers to a transistor switch. In Fig. 4 (not shown), the binary digit to be stored is determined by inhibit lines which thread cores in the first and third rows and in the second and fourth rows in a matrix plane of the type shown in Fig. 2.

Title: Improvements in epicyclic gearing
IPC: F16H37/08
Filed: 1921-10-18
Abstract: 196,005. Davidson, A. J. Oct. 18, 1921. Variable-speed and reversing gearing suitable for motor vehicles comprises a spur epicyclic train 10, 11, 13, Figs. 1 and 2, the outer member 13 being controlled by friction rollers 8 movable through the effort of the engine by a pedal 90, Figs. 10 and 12. When the gear is disengaged while a car is running, the rollers 8 are moved automatically to their anticipated positions so as re-engage without shock. The engine shaft 1, Figs. 1 and 2, carries a spider 9 supporting the planet gears 11 and also a bevel-gear 3 continuously driving the shafts 5 upon which the rollers 8 are splined. The sun gear 10 is secured to the driven shaft 2. A spring plunger 24 normally holds a lever 18 to the right so as to press a disc face on the outer gear 13 into engagment with the rollers 8. In the outer extreme position of the rollers 8, the epicyclic train turns solid. As the rollers 8 are moved inwards, the gear 10 slows, comes to rest, and is driven reversely. 'Collars 26 upon the rollers 8 are rigidly connected to nuts 49, Figs. 3 and 5, upon a screw rod 47 which is turned in one direction or the other to gear up or down by tilting the pedal 90 down by toe or heel respectively. For this purpose worm gearing 27, 29, Fig. 2, is continuously driving through gearing 30, 31, Fig. 3, clutch members 32 loose upon the rod 47. The opposite rotations of the rod 47 are effected by engaging clutches 35 alternatively. The clutches 35 are discs thrust forward through springs 38 by levers 36. The pedal 90 acts through a lever 46 to turn a cam 45 and so displace a rod 39 as to operate one of the levers 36. When the nuts 49 have been moved by power to extreme position, a snug 51 acts to break a spring toggle 41 and stop the shifting action. Disengagement is effected by a cam 74, Fig. 1, and the synchronizing movement imparted to the rollers 8 is brought about by the differential movement of the freed disc 13 and a loose disc 62 spring-pressed against the rollers. The discs 13, 62 have wormed edges meshing with wheels 61, 70, Fig. 3, respectively. The wheel 61 is contantly connected by gearing 59 to one side member 56, of a differential train. The middle member 55, Fig. 5, of the train is secured to the screw rod 47. The other side member 57 is connected by gearing 65 to a loose clutch member 68 upon the spindle of the wheel 70. A flange 15 on the disc 13 is connected by a lever 71 to a coacting clutch 69 so that the disconnecting movement of the disc 13 connects the clutch 68, 69 so that the train 56, 55, 57 becomes operative to drive the rod 47 and shift the rollers. The pedal 90, Figs. 10 and 12, is normally held to one side by a spring 92 so as to lie over a fixed guide bracket 93. To start the drive, the pedal is turned to parallel position and depressed to the position of Fig. 10. By tilting the perlal about a pivot 99, the speed changes are effected as described.
