Title: Improvements in Multiple Fuse Cartridges for Electric Circuits.
Inventor: FELDKAMP FREDERICK ANTHONY
IPC: H01H85/26
Filed: 1917-09-18
Abstract: 111,096. Feldkamp, F. A. Nov. 6, 1916, [Convention date]. Fusible cut-outs. - A magazine cartridge fuse comprises a casing 1 having a fixed cap 2 to which the fuse wires 25 are connected and a movable cap 4 carrying a contact member 27 which may be brought into connexion with any one of a number of contact plates 20 to which the other ends of the fuse wires are secured. At i:he end carrying the fixed cap, the wires are carried over the head 22 of a contact post 23 riveted to the fixed cap, and wound round its stem to which they may be soldered. The wires pass each through a separate powder-filled channel constituted by L-shaped strips 14 of insulating-material placed with their apexes together and their edges fitting into longitudinal grooves in the casing The strips 14 extend through a partition block 8 fixed within the casing and are cut away so as to accommodate between them the outer end of the contact plates 20 which pass through the partition block and are held by key portions 10 on the block extending into openings 19 in the contact members. To change the fuse in circuit, the end cap 4 is pulled outwards to enable the contact member 27 to clear the extended strips 14, rotated to a position opposite the next contact plate, as indicated by marks on the cap and on the casing, and then pushed inwards to force the contact member into engagement with the new contact plate.

Exhaust gases are cleaned of carbon dioxide and other burnable components by mixing the gases with air the quantity of which is 80 to 100 per cent. by weight of the gases at idling speed of the engine and not in excess of 30 per cent. by weight of the gases at full load of the engine, and sending the resulting mixture into contact with catalytic elements 20 on which is deposited an oxidizing catalyst such as a film of alumina impregnated with finely divided platinum, silver or copper. The elements may be in the form of streamlined section rods of low-porosity porcelain independently mounted transversely of the direction of gas flow, preferably in units u, and closely spaced in rows. adjacent rows being in staggered relation. The units may be mounted in a container 11 connected to the exhaust manifold of an engine A by a pipe 14 and a Venturi 15 provided with an air inlet 16, and may comprise opposed end plates 21 of ceramic material or metal coated with porcelain enamel, one end of the elements being secured in one plate and the other end of the elements being free to slide in the other plate. The first unit u of elements contacted by the gases initiates the oxidizing reaction of the gases and comprises from 50 to 75 per cent. of the number of elements in the subsequent units so that the intensity of the reaction is limited and the heat liberated distributed in a uniform manner throughout the length of the container. A pyrometer may be connected to a thermocouple in the exhaust outlet 17 to indicate the exit temperature of the gases. In modifications, (a) the container is in sections connected together, each section containing a single unit, u, and (b) the mixture of air and exhaust gases passes from an empty chamber into a section containing a single unit u and then to a further empty chamber joined to four subsequent sections each containing further units u, the empty chambers providing intermediate cooling of `the gases and the number of elements in the first unit being 15 to 20 per cent. of the number in the following units.

Title: Improvements in or relating to electrodynamic microphones
IPC: H04R1/38
Filed: 1967-03-23
Abstract: 1,133,049. Microphones. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 23 March, 1967 [26 March, 1966], No. 13661/67. Heading H4J. In an electrodynamic microphone, a sleeve may be moved, from a first position in which it seals the rear of a microphone capsule and inhibits entry of sound at the rear, to a second position in which sound can enter at the rear. In the first position the microphone has an omnidirectional characteristic while in the second position it has a cardioid characteristic. A housing 1 (Fig. 1), comprises a soundpermeable cap 2 fitted to a tubular metal casing 3. The diaphragm 5 of a microphone capsule 4 communicates with outside air through a protective member 6 and, in one position of a sleeve 8, through ducts (not shown) at the rear 7 of the capsule 4. The sleeve 8 is urged by a spring 9 against a rubber ring 10 at the capsule rear 7. The casing 3 is encircled by a rotatable collar 11 (Fig. 2) in which is a plastics sleeve 12. A recess 13 in the sleeve 12 receives a lug 14 inside the collar 11. An inclined surface 15a of the sleeve 12 bears on a pin 15b disposed in a longitudinal slot 16 in the casing 3 and screwed to the sleeve 8. Rotation of members 11, 12 forces the pin 15b to move forwards or backwards over the cam surface 15a, whereby the sleeve 8 engages or disengages the ring 10 to close or open the capsule rear 7. Alternatively, the casing (3), Fig. 3 (not shown), encloses a tightly fitting rotatable sleeve (8). A pin (15) secured to the sleeve (8) is movable in a transverse slot in the casing (8). The end of the sleeve (8) facing the capsule (4) has eccentric apertures (18) covered with gauze (19) and which in one position co-operate with apertures in the front of the casing (3) which in turn communicate with the rear of the diaphragm (5). The sleeve wall has apertures (20), which may contain acoustic resistance, and which in one position co-operate with apertures (21) in the wall of the casing (3). In one position of the sleeve (8) the apertures (18, 20, 21) are such that sound can reach the rear of the diaphragm (5).

A device for mounting panelling 16 on a surface 1, comprises a pin support member 3 having a groove 11 for pivotally engaging a hook member 2 projecting from the surface, means for locking the pin support member 3 in position on the hook member 2, and a pin 12 adapted to be fixed to the pin support member 3 and adapted to engage the panelling 16. As shown the pin support member 3 which includes a boss 4 for supporting cables 25 and which is formed from a plastics material is locked in position on the member 2 by a cotter pin 5 having a groove 7 near its free end which snap engages a constriction in a bore in the member 2. The pin support member may be released from the member 2 by severing the projecting end of the cotter to allow the member 3 to pivot downwardly. The panelling 16 is retained on the pin 12 by a button 13 which snap-engages the free end of the pin. In another arrangement, Fig. 3 (not shown) the hook member 2 is substantially Z-shaped in crosssection.

Abstract: 947,090. Methods of applying predetermined tensions to bolts. IMPERIAL CHEMICAL INDUSTRIES Ltd. April 18, 1962 [April 18, 1961], No. 13957/61. Heading F2H. A method of tightening nuts and like internally threaded members on to bolts, studs or screwed shafts &c., with the aid of hydraulic pressure includes the use of an assembly comprising an hydraulic piston 5 and cylinder 4, said cylinder being freely slidable over a bolt 2 to rest on a surface 1 against which the tightening takes place. The piston 5 threadably engages the bolt 2 and has a lower end which may be located in the cylinder 4 in which is subsequently formed an hydraulic chamber 8. Pressure is applied to the bolt 2 via the piston 5 by hydraulic fluid forced through a duct 9 from an externally connected supply at 10. Annular sealing rings 6a, 7a located in channels 6 and 7 respectively prevent leakage between piston and cylinder. The nut 2a may be tightened down when the hydraulic pressure produces elongation of the bolt, said nut being recessed on the underside to provide clearance for said piston. Other embodiments include a hydraulic piston located in specially formed recess in the body of the part upon which the nut is to be tightened. Specification 621,963 is referred to.
