Abstract: A glass composition having a coefficient of linear thermal expansion (0-300 DEG  C.) in the range 115 to 155 x 107 consists essentially of the following in weight per cent: .SiO2.29-56 .Na2O.8-24 .K2O.8-24 .Li2O.0-4 .TiO2.3-28 .Al2O3.0-6 .CaO.0-11 .MgO.0-11 the total alkali metal oxide content to be from 24 to 36; the total of CaO+MgO to be from 4 to 11; the total of SiO2+Al2O3+TiO2 to be from 54-70, and the total of Na2O+K2O+Li2O+TiO2 to be a maximum of 61.  The glasses formed from the above composition have annealing points of over 325 DEG  C. and softening points below 670 DEG  C.  As a result of these properties and a good chemical durability, the glasses are very useful in forming seals with such metals as copper and iron. A large number of examples are given.

Abstract: 531,104. Television ; preventing interference. STANDARD TELEPHONES & CABLES, Ltd. July 11, 1939, No. 20208. Convention date, July 13, 1938. Addition to 523,434. [Classes 40 (iii) and 40 (v)] [Also in Group XXXIX] The neutralizing signals which are used to balance out echoes due to reflections in the transmission medium as described in the parent Specification are derived from an artificial line 13 having a mis-matched termination 14, and, where a trail of artificial echoes is required, a mis-matched input impedance 12 also, the reflections being fed back into the line 1. The amplitude of the neutralizing signals depends on the extent of the mis-match, and the sign of the signals, relative to the main signal, on whether the termination and input impedance are greater or less than the artificial line impedance. The attenuation-frequency characteristic of the artificial line may be corrected or the characteristic of the neutralizing signals adjusted, by the terminal impedance. The impedances may be adjusted to produce a trail of neutralizing signals all of the same sign as or opposite in sign to the main signals, or alternating in sign and commencing with a signal of the same sign as or opposite sign to the main signal.

Abstract: 516,804. Engine governors. DAVEY, PAXMAN & CO. (COLCHESTER), Ltd., and PAXMAN, E. P. July 8, 1938,'No. 20293. [Class 135] A servomotor engine governor having a second servomotor for adjusting the spring load on the governor has the loading spring arranged between a pair of pistons contained within the second servomotor cylinder. The governor weights 1 act through a ball bearing 31 on a tubular control valve 26 having an annular pressure inlet recess 27 and exhaust port 30 adapted to co-operate with a ported follow-up sleeve to control the supply and exhaust of pressure fluid to and from the upper side of a piston 25. The follow-up sleeve is integral with the piston 25 and is secured to a bell-crank lever 37 whereby movements of the piston are transmitted to the control rack of an engine fuel injection pump, steam valve or other engine element to be regulated. The governor is loaded by a series of springs 9, 10, 11 arranged between a pair of pistons 8, 12 to come into operation successively as the lower piston is raised. This piston is operated by fluid pressure under the control of a manually operated piston valve 6 having a pressure inlet recess 18 and an exhaust' port 19 adapted to co-operate with ports 17 in a follow-up sleeve 13 secured to the piston. According to the Provisional Specification a manually operated device is provided for opening the fuel pump inlets during starting of the engine and as the oil pressure builds up it supersedes the hand operation. An additional manual control and spring can be provided to stop the operation of the piston and lock the whole fuel pump system. The hand lever which controls the governor loading may form part of the control gear of the boat or automobile so that as the main control wheel or lever is moved to various positions such as ahead, neutral or reverse the loading is adjusted at appropriate times and to the required extent.

A three-phase induction watt-hour meter comprises a single armature disc, three driving systems, each consisting of a voltage winding and a current winding disposed symmetrically about the axis of the armature disc, and a compensating plate to correct for errors due to the interaction of the stray fluxes due to each driving systems with those of the others, the compensating plate comprising a plate of ferromagnetic material having three radial arms and arranged so that each arm is magnetically linked, in an adjustable manner, with the end of a corresponding voltage core remote from the armature disc. To provide a preliminary reduction of the interaction of the fluxes due to the driving systems I, II and III, shown in plan view in Fig. 2, the armature disc 12 comprises a plurality of thin aluminium discs which are stuck together one above the other, with interposed insulation, each disc having five radial slots 24, the slots in successive discs being regularly offset from those in the preceding disc. Attached to the upper end of each voltage core is a solid iron arm 19 (see also Fig. 3), which extends downwards parallel to its voltage core and then inwards on the underside of the armature disc to lie between the poles of the current core and provide a pole co-operating with the pole at the lower end of the voltage core. Each arm 19 has a short extension 29 projecting inwards from the upper end of the voltage core; attached to these are brass members 30, 31 between which are formed slots which supports the peripheries of the radial arms of the compensating plate 25. The peripheries of the radial arms of the plate 25 are so shaped that by adjusting the position of the plate with respect to the voltage cores the magnetic linkage between the voltage fluxes may be adjusted to provide the desired compensation.
