Title: Fuse cartridge and method of manufacture thereof
IPC: H01H85/153
Filed: 1973-12-11
Abstract: 1450217 Fuse link IFO AB 11 Dec 1973 [11 Dec 1972] 57432/73 Heading H2G An end cap 5 for a cartridge fuse has a cylindrical portion 6 and a truncated hollow conical top providing a rim 16 which is flattened on assembly by contact cap 2 (Fig. 1, not shown) thereby compressing arc extinguishing medium 4. Good electrical connection between the two caps is provided by axial ridges (8, Fig. 5, not shown). After assembly the rim 13 of the contact cap is pressed down into the groove 14 in the tubular insulating body 1. The contact cap is of a piece of copper alloy and comprises a spade contact 9, whose plane passes through the tube axis, having grooves (17, Fig. 1, not shown) and a tapering edge. Diametrically opposite said spades are grips (10) shaped for ease of extraction and insertion of the fuse by an auxiliary tool (not shown). Multi-holed fusible elements 3 may be spot welded and/or soldered to the outer faces of the end caps, bores 15 being provided in each contact cap through which extra solder may be supplied. There may be a varied number of said elements (three, for example) which may be of copper provided with a silver sheath. A leaf spring 22 normally held as shown is released when the wire 20 melts thus signalling a blown fuse. The fuse interior may be filled with selected silica sand which becomes compacted on assembly. A detailed method of manufacture is given.

Abstract: 1446078 Thermo-aluminic processes BUCK KG 14 Dec 1973 [14 Dec 1972] 58152/73 Heading B3V A housing for a thermit demolition charge has an ignition transmission window 14 in its wall 10 and means 12, 13 for connecting the housing to a second housing also having an ignition transmission window 15 in its wall 11. Thus, only one fuse is required, the hot melt in the cube-shaped housing of one device, after melting foils 16, 17, ignites the charge in the housing of the adjacent device. Two opposite sides 10 of each housing may each be formed with a tongue 12 and the other two sides with a groove 13 to enable ready interconnection of the housings. Alignment is achieved when a projection 19 enters a recess 18. Alternatively, Fig. 2 (not shown), each of the four sides of a housing may be formed with a groove (22 or 23) for use with a separate connector (30) also serving as an ignition transmitter. An electric or manual friction igniter is attached to one of the charges. Covers protect exposed windows on sides not carrying an igniter. Transmission windows may also be formed in the ends of the housings to enable vertical stacking. Interconnectors may extend between the opposed windows of a housing so as to cross each other and facilitate ignition.

Title: Improvements in or relating to telecommunications exchange systems
IPC: H04Q3/00
Filed: 1969-12-03
Abstract: 1,242,977. Automatic exchange systems. SIEMENS A.G. 3 Dec., 1969 [4 Dec., 1968], No. 58970/69. Heading H4K.  One out of a plurality of free junctions is selected by marking a set of gates (of which there is one gate per junction) pertaining to the required direction, connecting the free/busy test wire of each junction to its gate and then successively applying an enable signal to another input of the marked gates until one of them produces an output, this output together with the setting of the enabling means providing a unique indication of the identity of the selected junction. As shown, the c wire between each switching network outlet (KF) and its associated junctor VS is connected to an individual AND gate, e.g. Kqr1 In response to routing instructions, ZO causes translation field BR to mark those of gates K11-Kqrp which pertain to the required direction. Three C-wires carrying - ve free potential (as opposed to busy earth via contact b) thus cause their associated gates to open and hence actuate group gates K21-K2qr. The outputs of the latter are applied via a diode matrix to one-only selector AK1, AK2 whereupon the portion AK1 inhibits all the K2 gates except one and applies a start signal to enabling selector AK3. The latter removes all the enable potentials from its outlets 1-p and then reapplies enable potential to its outlets one-at-atime. The final output from a gate, e.g. Kqrl stops the selector and the identity of the corresponding junction as denoted by the settings on AK1, AK2, AK3 is supplied to the marker M which then proceeds to select a route thereto. Testing.-The contact Sp in the junctor is opened for testing so that during junction selection an indeterminate potential appears on the C-wire. To overcome this, transistor T2 is pulsed-on to provide an artificial busy earth. Statistical metering.-Since such metering should not be influenced by artificial busying caused by testing procedures it is arranged that transistor T1 should be pulsed-on to provide a free indication whenever statistical metering is required during the course of normal testing.

Thus a free falling curtain of coating composition is formed between a pair of edge guides with a support material being passed through the curtain in a transverse direction to the plane thereof. To obtain a substantially uniform coating thickness between the trailing ends of the brushes 32, attached to the edge guides, the edge guides are moved apart by turning a cam 23 by means of a handle 25, until the curtain begins to thin out in a vertical line about 1/16 inch in from the edge guide, giving rise to coating as shown in Fig. 12, the brushes then being moved back towards the centre about 1/32 inch so that the thinned out portion disappears and an even coating as shown in Fig. 11 is obtained. The invention is used with curtain widths of 42 inches, while coating at speeds in the range from 150 to 250 feet per minute.
