Abstract: 505,071. Sewing - machines ; gearing. FAIRWEATHER, H. G. C. (Singer Manufacturing Co.) Oct. 20, 1938, No. 30319. [Class 112] [Also in Group XXIV] A sewing-machine feed-wheel is connected to a feed-actuating shaft through change-speed gearing comprising constant-mesh gears selectively brought into operation ; the feed-shaft is driven from a transverse shaft. In the arrangement shown, applied to a machine similar to that described in Specification 278,582, [Class 112], except for the replacement of the presser-foot and feed-dogs by a presserwheel and a feed-wheel 50, the feed-wheel shaft 49 is driven through change-speed gears 53, 56 from an intermediate shaft 48 geared to the feed-actuating shaft 35; the shaft 35, instead of forming a continuation of the shaft 22 from which the needle-vibrating mechanism derives its motion, is driven from the loop-taker shaft 27 through a transverse shaft 41 geared to the shafts 27, 35 and carried by a hanger 38 supported on extensions of bearing bushes 33, 36 in which those shafts rotate. The feed-wheel shaft 49 and the intermediate shaft 48 are carried by a bracket 46 which is rotatably mounted on an extension of the bearing bush 36 and forms a housing tor the gears 53, 56; the other end of the bracket 46 is supported by a screw 47 by which the height of the feed-wheel may be adjusted. The change-speed gears include three trains of different ratios, each comprising a wheel 53 fast on the shaft 48 constantly in mesh with a wheel 56 free on the shaft 49. The wheels 56 are selectively secured to the shaft 49 by a key 61, Fig. 7, sliding in a slot in the shaft and moved along by a pin on a sliding ring 66 engaging a notch in the key, a pin 68 in the shaft slot preventing complete withdrawal; the key is pressed into the engaging position by a leaf spring 65 fixed to it, and is pressed back while being shifted from one wheel to another by washers 59 placed between the wheels. Specifications 243,237, 325,424, [both in Class 112], and 374,322 are referred to.

The invention also includes ignition advance apparatus for an internal combustion engine according to claim 2 of Parent Specification comprising an angular coding unit 1A, Fig. 1, which includes a rotatable element 100 which, associated with a position detector 120 delivers a rectangular reference signal of constant width, a constant frequency pulse generator 130, an inverter 140 for the reference signal, a first counter 150 which, controlled by a monostable device 160, counts the number N1 of pulses from the pulse generator 130 during one of the states of the reference signal, and which by means of a first logic element memorizes the number N1 during the other state of the reference signal, a binary divider 180 which divides the number N1 by another number N2 so as to obtain a number N3, a second counter 190 which by means of the inverter 140 and a second logic element 200, counts the pulses from the pulse generator 130 during the other state of the reference signal, and a comparator 210 of the number of pulses counted by the second counter and of the number N3 from the binary divider 180. When these two numbers are equal there is obtained at the output of the comparator a pulse corresponding to a determined value of the displacement with respect to the previous pulse, which pulse is applied on the one hand to the second counter 190 to effect its return to zero and on the other hand, and with or without the aid of a code converter 4, to one of the inputs of the comparator 3 which triggers the ignition signal when the coded number A coincides with the coded number B. Other embodiments are described. Specification 1473214 is referred to.

[Also in Division H2] In a circuit (Fig. 2) producing a non-linear voltage function of an input current function I, e.g. for operating a maximum current relay with delayed release dependent on current, a non-linear resistance network 1 in series with a variable resistance 4 accepts current I 2  to produce output voltage drop V, and a shunt comprising resistance 2, collector/emitter circuit of transistor 5, and variable resistor 3 accepts current I 2 ; the transistor base being connected to the junction of 1, 4. Then input current I = I 1  + I 2  and for all values of input so that the non-linear network current is maintained constant independently of input current. In modifications (Figs. 3, 4, not shown) the base/emitter drop in the transistor is compensated by a diode in series with resistance 4, or by a second transistor with collector/emitter circuit in series with 4 and base interconnected with base of the first transistor for energization over a further resistance from input current. Plural non-linear networks may be connected in parallel and shunted by a common transistor/resistance circuit.

Abstract: 803,929. Flameless combustion. HELBERGER, J. H. Oct. 15, 1956 [Oct. 14, 1955], No. 31367/56. Class 75(1) Flameless combustion of liquid or gaseous organic substances is effected by amorphous chromic oxide (Cr 2 O 3 ) or mixed metal oxides containing chromic oxide used as catalyst for the combustion. In the apparatus shown liquid fuel drips from a funnel 6 through an iron tube 3 projecting into grains 1 of chromic oxide in a perforated iron basket 2 resting in the upper end of a vertical air tube 7. The lower end of the iron tube 3 is loosely blocked with asbestos wool 4. At starting the surface of the catalyst is wetted with fuel and combustion is initiated by heating the catalyst surface with a hot wire or a gas flame. The fuel may be allowed to rise upwardly into the catalyst for example by using a wick. The air may be introduced from below, from above or from the side. The supply of fuel is preferably regulated so that the main combustion takes place inside the catalyst mass. Numerous methods for the production of the catalyst are described The fuels may be alcohols, ketones, esters, Diesel oil, acetic acid or substances such as lignite wax, naphthalene, stearic acid which are liquid at the operating temperature of combustion or solutions of such substances in organic combustible solvents.
