Title: Method of manufacturing multi-layered composite material
Inventor: KANDA EIZO
IPC: B21C37/04
Filed: 1969-09-03
Abstract: 1,247,282. Making composite articles; coil spirals. E. KANDA. 3 Sept., 1969 [3 Sept., 1968], No. 43684/69. Headings B3A and B3E. A multi-layered composite is formed by inserting a coil 7 formed by a laminated strip 6 into a sheath 8 having an inner diameter substantially equal to the coil diameter and reducing the diameter of the assembly, e.g. by drawing, extrusion or rolling. The sheath may be subsequently removed. In an example, a Pb-Al-Sn composite is rolled to form strip 6 of 0À1 mm. thickness, which is coiled into a coil 7 by rotating rollers 4. The diameter of the coil 7 is determined by one of the roller bearings 3, acted upon by a spring 5, engaging a bolt 2. The coil 7 is inserted in a copper or aluminium sheath 8 sealed at both ends by plugs 9, 10 and the sheath drawn from 15 mm. diameter to 8 mm. diameter. Part of the sheath is further drawn into wire having a diameter of 0À19 mm. and a layer 6 thickness of about 140 Š and the other part rolled into strip of 0À06 mm. thickness. In other examples, the composite strip 6 comprises Al-Pb, Al-Nb-Al, Pb-Al-Pb having oxide and silicon grease coats, and Pb-Al-Sn-Al-Pb which is folded and rolled a plurality of times  to form a strip 6 having a plurality of layers. A tubular assembly wherein the coil 7 is positioned on an inner sheath may be worked using a die and mandrel. The composite material may be used as a superconductor or a high frequency magnetic material.

Title: Improvements in signalling equipment
IPC: H05B39/09
Filed: 1963-11-08
Abstract: 977,497. Flashing light Indicators; lamp failure alarms; road traffic signals on vehicles. ROBERT BOSCH G.m.b.H. Nov. 8,1963 [Nov. 21, 1962], No. 44074/63. Headings G4F, G4N and G4Q. [Also in Division H3] A lamp flasher circuit, Fig. 1,comprises a power transistor 13 in the supply circuit to the lamp 10, controlled by an astable multivibrator 16,17; and a protective transistor 25 having its emitter-collector path in a supply lead to the multivibrator, and its base connected to the lamp. On closing the switch 12, a small current flows through the lamp 10 and resistor 15 so that the lamp warms up and the base potential of transistor 25 increases until it conducts applying powers to the multivibrator 16,17. Transistor 13 is periodically switched on and off by the multivibrator to short out resistor 15 and thus flash lamp 10. If lamp 10 goes short circuit, transistor 25 switches off removing power from the multivibrator, and so switching off transistor 13 to protect it from excess current. In a vehicle lamp flashing circuit, Fig. 2, one of the multivibrator cross coupling paths is completed via emitter followers 39,13,37. Failure of one of a pair of indicator lamps 30a, 30b or 31a, 31b reduces the current through transistor 13 and varies the switching rate of the multivibrator.

Filed: 1974-10-29
Abstract: 1484874 Container traffic; vehicle container loading J A RUMELL 29 Oct 1974 [29 Oct 1973] 46632/74 Heading B8Q [Also in Division B7] In a transport vehicle a chassis 12 is releasably attached to a tractor 11 and the chassis has a flatbed 45 which is slidably and tiltably supported on a wheeled tandem 46, there being also a wheeled cargo container 14 removably mounted on the flatbed 45. The tractor 11 is coupled to the chassis 12 through a king-pin coupling 16. The container 14 has hydraulically extensible and retractable support dollies 19, 20 which run in longitudinally extending guide tracks 34, 35, Fig. 4, provided on the chassis 12. Twist locks 36, Fig. 4, are located below the guide tracks 34, 35 for securing each corner of a container positioned thereon. The chassis 12 has a flatbed 45 supported on a tandem 46 having two sets of wheel axles 55a, 55b connected by a pair of leaf-spring assemblies 56 under which a tandem axle 58, Fig. 6, is rotatably supported. A tandem frame 60, Fig. 6, supported on the axle 58, has laterally extending support members 63 upon which longitudinal bottom plates 52a of the flatbed frame 52 ride. L-shaped clamps 73 bolted to the support members 63 overlie the bottom plates 52a of the flatbed which is thus prevented against lifting from the tandem 46. The tandem 46 may be locked to the flatbed 45 by a locking pin mechanism 62, Fig. 9, including a pair of outwardly biased pins 64 engageable in respective apertures 65 in the flatbed frame 52. By pulling a handle 72 the rotary link 68 may be rotated to withdraw the pins from the apertures 65 against the biasing force of springs 71. In operation, to dislodge the container 14, the locking mechanism 62 is disengaged to allow sliding movement of the flatbed relative to the tandem 46. By braking the tandem wheels 48a, 48b and backing the tractor 11 until a fixed stop 78 is engaged by the tandem the flatbed may be tilted about the axle 58 by operation of hydraulic cylinders 80 pivoted between tractor extension 15 and the flatbed 45. Guide ramps 90 are lowered and the twist locks 36 unlocked so that the container with its dollies 19, 20 extended may roll off the flatbed under gravity. A new container may be drawn on to the tilted flatbed by a winch 89. Two containers 14a, 14b may be loaded on to the flatbed 45 by passing the winch rope under the first loaded container and connecting it to the second. Alternatively the two containers may be coupled together and loaded on the flatbed.
