Abstract: 624,422. Direct connections between conductors. SIMPLEX ELECTRIC CO., Ltd., and REED, J. P. Feb. 1, 1946, No. 3207. [Class 38 (i)] [Also in Group XI] An electric heating element complete with end couplings is made by disposing a resistance wire 10, with flexible or semi-flexible end connecting wires 11, within a metal tube 13 filled with electrically-insulating heat-conducting material 16, the connecting wires passing out through crushable spacing washers 15 and a permanent seal 17 of fused glass, steatite or other material or a temporary seal such as a rubber bung. The diameter of the tube is then reduced completely along the length of the resistance wire and also along those portions of the tube that enclose the crushable spacing washers 15. If the ends of the tube have been permanently sealed these ends are left unreduced, but if the ends have been temporarily sealed, as above, the whole length of the tube is reduced, the temporary seals then being removed and a permanent seal 17 inserted. In all cases the ends of the tube may be finally sealed with a flanged bush 18 of steatite or other material and the connecting wires 11 may be indented or flattened at one or more positions such as 12 to resist endwise or other movement. Specification 592,124, [Group XL], is referred to.

Title: Improved machine for cleaning the matrices for type setting and casting machines
IPC: B41B11/00
Filed: 1927-02-14
Abstract: 278,572. Christel, K. Feb. 14, 1927. Cleaning matrices. - Type-bar matrices are cleaned by two passages through a machine through which they are caused to circulate, one broad face being cleaned at each passage. The matrices are caused to circulate by the centrifugal force of a rotating disc h, Fig. 1, by which their broad faces are cleaned, the, matrices being then projected through a roof-shaped channel n, o into a collecting-channel a. The disc h consists of a number of layers of woven fabric. The part o of the channel is twisted, so as to turn the matrices through an angle of 180‹. Matrices that do not reach the top of the channel, and therefore fall back, are caused to pass out of the channel. The matrices are advanced from the collecting-channel a to the disc h by tappets c, Fig. 16, on an endless chain b, and are temporarily locked beneath the disc by pivoted hookshaped bars g, which engage between their ears. A locked matrix is released by the action of the following matrix on inclined parts i of the bars g, and is projected forwards by the disc under the guidance of rails l, m and a spring bridge f. The matrices in the channel a rest upon an adjustable angle-piece s, Fig. 11, and a spring t prevents the advance of more than one. The first stage of the cleaning is effected by a brush d, Fig. 1, and by a pad e, comprising a thin blade-steel support 7, Fig. 7, secured at its ends between rails 8, 9, and having passing around it an endless cleaning-ribbon 10 of suitable fabric. The ribbon can move about the support, on which it is stretched by a blade-spring 11, and is caused to bear uniformly upon the matrices by a second blade-steel support 12. Benzine is delivered to the ribbon from a container 2. The brush d, pad e, and disc h are so mounted that they can be turned up, in order to give access to the parts below. The longitudinal edges of the matrices are cleaned by a rotating felt disc 4, which projects into the channel a,. and by an emery strip located below the disc.

Abstract: 1406245 Gas turbine engine fuel supply; centrifugal pump control LUCAS INDUSTRIES Ltd 14 Dec 1972 [29 Jan 1972] 4311/72 Headings F1C and F1G A fuel supply arrangement for a gas turbine engine comprises first and second centrifugal pumps, the inlet of the first pump providing an inlet for the arrangement, a conduit for supplying fuel to the engine and containing fuel control apparatus, and valve means responsive to the fuel pressure in the conduit downstream of the control apparatus and operable when the fuel pressure exceeds a predetermined value to establish a connection between the outlet of the first pump and the inlet to the second pump and a connection between the outlet of the second pump and the conduit and, when the fuel pressure is less than the predetermined level to connect the outlet of the first pump to the conduit and shut off the connection between the inlet of the second pump and the outlet of the first pump. Fuel supplied to the inlet of a pump 10 is delivered to an engine 13 via a conduit 15 containing a flow control 16. When the fuel pressure downstream of the flow control 16 is low, a valve 20 is in the position shown in which a port 27 is open to allow fuel to be delivered by the pump 10 to the conduit 15 via a non-return valve 28. When the fuel pressure downstream of the flow control 16 has risen to a value at which it opens a valve 18, the valve 18 allows fuel at this pressure to act on the piston 22 of the valve 20 to move the latter to a position in which it closes the port 27 and opens a port 25. The pump 10 then delivers fuel via the port 25 to the inlet of a further pump 11, which then delivers fuel via a non-return valve 14 to the conduit 15. Movement of the valve 20 is damped by a restriction 32.
