Title: Improvements relating to the propulsion of bicycles and tricycles
IPC: B62M1/12
Filed: 1924-08-19
Abstract: 230,127. Wood, W. Aug. 19, 1924. No Patent granted (Sealing fee not paid). Combined hand and foot driving-mechanism.- Foot propulsion is assisted by oscillating handlebars, which, by means of wires, rods, &c. drive free-wheels on a supplementary axle, situated near the main crank axle, and connected independently to the axle of the rear driving-wheel. Fig. 1 is an elevation of divided handle-bars a, b, supported by a fork h at the head of the steering- column j, and connected by plates y. The bars drive, by their wedge-shaped ends x, a grooved centre portion of a driving-pin f. As shown in Fig. 3, the handle-bars drive separate pins f, g, the centre portions d, e of which are cylindrical and pivoted on a pin 2 carried by a support k and are driven by forked ends of the handle-bars which embrace them. The driving-pins may be connected by a pin 3. Pairs of wires, attached by adjustable washers n to each driving-pin, are connected to chains which, after passing around sprockets on the supplementary axle, are coupled together by a wire passing over a pulley; springs may be substituted for the wire and pulley, or provided additionally, for returning the chain. The supplementary axle is carried by a bracket, either integral with, or clamped to, the down tube of the cycle frame, and has its chain-wheel on the side opposite to the ordinary chain-wheel. The top bar of the cycle frame may be slotted to allow the wires to pass, or a pair of bars may be provided, the wires passing between them.

Abstract: Dimethyl substituted iminodibenzyls of the general formula: <FORM:0792615/IV (b)/1> are prepared by oxidizing a 2-nitroxylene in the cold with an alkyl formate or alkyl nitrite in the presence of an alkali metal alcoholate, reducing the dinitrodibenzyl so formed to the diamino compound and heating to about 280-320 DEG  C. a mineral salt of the said diaminodibenzyl.  In examples, o-nitro-p-xylene is reacted with isoamyl formate, or butyl formate, in the presence of sodium or potassium ethylate and in an inert solvent such as cyclohexane at a temperature below 5 DEG  C., the 2 : 21-dinitro-4 : 41-dimethyldibenzyl is reduced by hydrogen in the presence of Raney nickel to the diamino compound, and this converted into the diphosphate salt which is then heated to 280-320 DEG  C. to form 3 : 7-dimethyl-iminodibenzyl.  By oxidizing 4-nitro-1 : 3-dimethyl benzene with amyl nitrite, and heating the mono hydrochloride of the diamine as above, 2 : 8-dimethyl-iminodibenzyl is formed.

Filed: 1931-09-26
Abstract: <PICT:0379880/IV/1> <PICT:0379880/IV/2> Freshly coagulated artificial threads are passed over a guide roller and allowed to fall on to an endless band moving, continuously or intermittently, slowly in comparison with the speed of production of the thread so that the thread falls in convolutions on the band.  The coiled material is treated on the band with washing and other liquids and after drying either on the band or after removal therefrom, is passed to a winding device. The band may be oscillated as well as moved forward so as to lay the thread in a zig-zag path.  The band may be pervious or impervious and may be made of "Monel Metal," rubber, or canvas. The treating liquids may comprise water, sodium sulphide solution, sodium hypochlorite solution, and soap solution.  As shown in the drawings, a coagulated thread A from a bath B passes over a wheel C and drops on to an endless conveyer band D which is driven slowly forward continuously or intermittently by rollers E, F and is moved from side to side by means of a wheel G and connecting-rod H.  The thread may remain under the influence of the spinning bath liquid carried by it so that it may be completely set before it comes under the sprays K. L, M of washing and other treatment liquids.  Rubber rollers P remove excess of one liquid from the thread before it is subjected to the action of the next liquid or before it passes to the drying device Q. Specifications 16495/07, [Class 2.

Abstract: 714,440. Cathode-ray tubes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Nov. 23, 1951 [Nov. 27, 1950]. No. 27516/51. Class 39(1) In a cathode-ray tube in which a ribbon beam is deflected over one or more collecting electrodes, the deflecting system comprises two flared plates, one or each of the plates, to which a varying control voltage is applied, being divided into two or more parts 4, 5, at least the part nearest a subsequent grid electrode 6 at a potential of zero or a few volts being given a fixed positive voltage greater than the highest value of the varying control voltage. In the arrangement shown plate 3 is kept at a fixed potential of 150 volts, plate 4 varies from 70 to 220 volts, and plate 5 is fixed at 300 volts. Grid 6 is followed by positive perforated collector electrode 7, suppressor grid 8 connected to 6, and collector anode 9. When the beam is deflected towards plate 4 the electrons repelled by grid 6 go to plate 5. Stray electrons striking plate 4 will generate secondaries which go to plate 5 so that the net current to plate 4 is almost zero. The right hand deflection plate may be divided into several parts alternately connected to a variable and fixed voltage. Both plates may be subdivided, as when both carry varying voltages but when one of them is to be kept at a fixed potential preferably only the variable potential one is subdivided. Grid 6 has a lens effect so as to focus electrons on to the slots in electrode 7.
