Title: Machine for the application of seals to containers provided with a feeding device
IPC: B67B3/064
Filed: 1971-09-21
Abstract: 1358894 Capping bottles; orientating articles SIMONAZZI A & L SpA 21 Sept 1971 [24 Sept 1970] 43936/71 Headings B8T and B8S A machine for applying crown caps to containers includes a series of heads 1, Fig. 1, carried by an oblique plate 2, which is rotatable about a column 11. A drum formed of upper and lower parts 4, 7 is similarly rotatable and means is provided to adjust the position of the plate 2 relative to the drum. The caps are supplied from a hopper 50, Fig. 2, to the heads 1 by means of a vertical duet 51 and a horizontal duct 52 having a conveyer belt 53 and a portion 55 which includes a divider (54), Fig. 3 (not shown), which separates the caps according to whether the cap concavity lies in one direction or the other. Caps of each of the two concavities are then passed into separate slots (56, 57), Fig. 4 (not shown), which diverge, Figs 5-6 (not shown), to supply the heads 1 with the caps lying with their concavity facing the conveyer belt 53, Fig. 7 (not shown). The caps are passed from the conveyer 53 to the guide (32), Fig. 8 (not shown), by a'disc (31), Fig. 9 (not shown). The heads 1 have a piston (21), Figs. 11, 12 (not shown), which contains a magnet which retains the cap until sealing is completed by a member (22).  The column 11 contains a rod 41 which is connected at its upper end 12 to the frame 44 and at its foot to a reduction gear 13 and thereby to a hand wheel 42 by which the rod may be rotated. Rotary motion is transmitted from the gear 6 to the lower drum 7, and to the upper drum 4 via a grooved connector 15. The container 17 is held by guides 18 and 9.

Abstract: 1424389 Isostatically compressing nuclear reactor fuels HOBEG HOCHTEMPERATURREAKTOR - BRENKTELEMENT GmbH 20 Sept 1973 [20 Sept 1972] 44098/73 Heading B5A A process for isostatically compressing fuel or absorber elements for high temperature nuclear reactors comprises isostatically compressing a mixture of binder-containing graphite powder and coated fuel particles or absorber particles in a plurality of stages, each stage being carried out at a higher pressure than the preceding one and in a different rubber mould to obviate the need to remove air from the pressing powder and to minimize wear of the rubber, e.g. silicone moulds. To produce elements having a carbon only outer shell, three stages are required. The first stage comprises producing a porous core under low pressure, e.g. 15 kp./cm.<SP>3</SP> from the above mixture. The second stage comprises applying a coating of binder-containing graphite powder to the porous core under a slightly higher pressure, e.g. 150-170 kp./cm.<SP>2</SP>. The third stage comprises compressing the coated porous core under a high pressure, e.g. 2À5 tonnes/cm.<SP>2</SP>. The binder, e.g. phenolic resin is then coked by heating the final pressing to 800‹ C. and calcining in vacuo at 1800‹ C. The mould for the final pressing may be evacuated. The moulds may comprise ellipsoidal or cylindrical cavities for producing spherical or cylindrical elements. Spacer ribs for cooling gas may be moulded in situ on the elements. The moulded elements may be trimmed to size.

Title: Drive circuit for magnetic heads
IPC: G11B5/02
Filed: 1959-12-31
Abstract: 893,095. Magnetic amplifiers. SPERRY RAND CORPORATION. Dec. 31, 1959 [Dec. 31, 1958], No. 44455/59. Class 40 (9). [Also in Group XIX] In a phase modulation system of recording the circuit between the inputs and the recording head includes a shunt to disable the unused input. An impulse on lead 12 representing 0 is amplified at 16 and fed through point a, the primary 31 of transformer 33, point b and shunt resistor 34. If switch 46 has been closed the current in the secondary winding 40 flows through the left-hand coil of writing head 37 to effect a recording in the one sense as shown in line Ip of Fig. 2. The output of amplifier 16 is also fed to a further amplifier 22 with a slight delay, resulting in reversal of the current through transformer 33 and energization of the right-hand coil of writing head 37 to effect recording in the reverse sense in the second half of the element. For an impulse on lead 13 representing 1, the right-hand coil of head 37 is effective before the left-hand coil. Magnetic amplifiers. The amplifiers 16, 18, 20, 22 may be of the type described in U.S. Specification 2,709,798, or as shown in Fig. 3. Core 60 is normally driven to negative saturation by reset coil 82. When an input impulse is applied to terminal 12, however, the core is driven momentarily to positive saturation. A power pulse PP following the input pulse then encounters low resistance and produces an amplified output through rectifier 24. In the modification of Fig. 4, using sine waves, core 90 is normally in a state of negative saturation due to +ve half-cycle of blocking pulse BP acting on winding 99 and - ve half-cycle of power pulse PP acting on winding 94. An input 12 in the form of a +ve half-cycle overcomes the blocking pulse BP so that the +ve half-cycle of power pulse PP then meets low resistance and passes to output c. The waveforms are shown in Fig. 5.
