Abstract: 757,483. Speedometers. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 12, 1953 [July 30, 1952], No. 19201/52. Divided out of 756,028, [Group VIII]. Drawings to Specification. Class 106 (3). [Also in Group VIII] A stroboscopic disc having markings on it is driven by the yarn being fed to a knitting- machine, and a lamp operated to flash in relation to the machine speed directs its beam on to the disc such that the relation between yarn consumption and machine speed can be observed by the apparent stationary position or movement of the markings. If necessary adjustment is then made to obtain the apparent stationary position of the markings, in which position the desired relationship between the machine speed and yarn consumption exists. Alternatively the disc may be driven by the machine and the lamp actuated by the yarn. In a machine which has a number of yarn feeding positions the relationship between the yarn consumption at each position and the machine speed can be measured by providing a lamp operated by the machine and which is placed in turn adjacent a stroboscopic disc at each yarn feeding position. To enable the apparatus to check the consumption where it is desired to alter the rate of consumption during production, the disc is provided with a series of marks corresponding to the various desired rates of consumption.

Abstract: 689,762. Oil gas. UNITED ENGINEERS & CONSTRUCTORS, Inc. Aug. 21, 1951 [Aug. 23, 1950], No. 19668/51. Class 55 (ii). A generator for use in a cyclic process for the manufacture of a gas rich in hydrogen and carbon monoxide from a gaseous or vaporous hydrocarbon and steam with or without air comprises a combustion chamber 1 and two reaction chambers 2 and 3 each having two heat storage beds 4 and 12, 5 and 13 with an intermediate bed of a catalyst 8 and 9 respectively. During a heating period a fluid fuel and air are admitted to the combustion chamber 1 via lines 32 and 31, the hot gaseous combustion products passing in parallel through the reaction chambers to atmosphere via stack valves 16 and 17. During a gas-making period the hydrocarbon and steam are admitted in one run through lines 18 and 20, passing in series through both reaction chambers, the products being withdrawn via line 27 and three-way valve 25. In the next run the flow of reactants is reversed, hydrocarbon and steam being admitted through lines 19 and 21 and the gases withdrawn through line 26 and three-way valve 25. An intermediate heating period may be employed between the two runs. During the gas-making period air may be admitted through lines 22 or 23 or line 31 and the combustion chamber 1. Steam and/or hydrocarbon may also be admitted to the combustion chamber during the gas-making period to control the temperature therein. The hydrocarbon reactant may comprise natural gas, refinery oil gas or vaporizable liquid hydrocarbons such as butane or the heavier hydrocarbon distillates. The temperature employed depends on the nature of the hydrocarbon used, thus for example when using natural gas a maximum average temperature of the heat storage beds would be about 2000‹F and a minimum about 1400‹F. The catalyst is preferably nickel or cobalt but may be vanadium, chromium or platinum disposed in a suitable refractory carrier. In a modification the combustion zone may contain a bed of solid fuel which is blasted during a heating period. In a further modification the two reaction chambers are arranged side by side. Specification 668,978 is referred to.
