Patent GB-380508-A (GB)
Title: Improvements in telephone systems
IPC: H04Q1/32
Filed: 1931-06-18
Abstract: 380,508. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON, 33, Kungsgatan, Stockholm. June 18, 1931, No. 17727. Convention date, Aug. 4, 1930. [Class 40 (iv).] Impulses are transmitted by the insertion of a resistance in the loop instead of by breaking of the loop, a separate polarized impulse relay PR being employed in addition to the usual line relay LA, Figs. 1 and 2, or SM, Fig. 3, which remains energized to hold the connection. This prevents the possibility of a subscriber obtaining a prohibited number by repeated operation of his switch-hook where the impulse dial is blocked as regards certain digits. In Fig. 1 the polarized relay PR is shunted by a choke coil Si. When the impulse dial Fs operates, a resistance r is repeatedly inserted in the loop, and an operating current opposing the weak stationary current flows through the relay PR due to induced voltage in the choke coil Si. In Fig.2 the relay PR is connected to a potentiometer as described in Specification 267,499, [Class 40 (iv), Telephones &c.], and each winding is in parallel with a winding of the line relay LA. In Fig. 3 the relay PR is operated by the discharge of condensers cr1, cr2, which are charged by the current variations in the loop, and impulses of a similar nature may be repeated, for example over a junction, by a relay JR. The Specification as open to inspection under Sect. 91 (3) (a) states that the de-energization of the relay PR, Fig. 1, while LA is held may be applied for bringing a third party temporarily into the connection. For this purpose the contact c may be actuated by a pushbutton. This subject-matter does not appear in the Specification as accepted.

Abstract: 734,068. Forcing liquids under gaseous pressure. AER-RIANTA TEORANTA, and MALONE, P. June 29, 1953 [Sept. 5, 1952], No. 17959/53. Class 102 (2). An accumulator 1, Fig. 1, having a controlled outlet (not shown) for dispensing high pressure liquid, e.g. water for car washing &c., is alternately supplied from containers 2 with liquid under gaseous pressure, e.g. compressed air, controlled by a valve 13, having a connection 12 to a compressed air supply, connections 35a to the atmosphere and a connection 36a to each container. The valve 13 slidably mounts a piston valve member 17, Fig. 5, movable into either of two end positions by compressed air supplied through pilot pipe 37, one connected to each container. On the level of the liquid in a container 2 falling sufficiently a float-actuated needle valve 40 opens to allow some of the compressed air, which has entered that container to act on the associated end of the valve member 17 to move it to its other end position so as to exhaust the air from the container and open the other container to the compressed air supply and so transfer the water in that container to the accumulator. Initially the containers 2 are filled, and the accumulator 1, partially filled with water from a common supply pipe through pipes 5 and non-return valves 9, the air in the containers being exhausted to the atmosphere by manual manipulation of the valve member 17 by the insertion of a tool through the disconnected compressed air connection 12. Air in the accumulator 1 is trapped to form an air cushion. The connection 12 is then connected to the compressed air supply with the valve member 17 in one of its end positions whence the apparatus operates as explained above until the supply of compressed air is cut off. A spring-loaded plunger 30 engages latter in its end positions.

Title: Heat treatment of strip metal
IPC: C21D9/56
Filed: 1949-07-07
Abstract: A continuous furnace for annealing metal strip especially steel, but also copper, brass, aluminium or magnesium, has a heating zone, a cooling zone and an arrangement of rollers for cold working the steel (see Group XII).  The heating zone consists of gas heated incandescent panels which heat the strip by radiation and are movable towards, or away from, the strip for temperature control and may be actuated in response to an electrical temperature-sensitive device. Heating is effected in a neutral atmosphere and a reduction zone may be interpolated between the heating and cooling zones to reduce any oxide formed on the strip during heating.  The cooling is carried out in a non-oxidizing atmosphere, e.g. 95 per cent N2, 5 per cent H2.  A skim pass may be included after the cooling process. For steel the metal is heated to 1300-1800 DEG F. and is cooled slowly to 900 DEG F. and then as quickly as possible to below oxidizing temperature or 300 DEG F. before emerging into the atmosphere.  It is stated that strip covered with lubricant may be annealed without cleaning prior to the heat treatment as the oil is vaporized in the heating zone, and passed away into the exhaust gases. Specification 496,146, [Group XII], is referred to.
