Abstract: 102,482. Emerson, W. F. Nov. 26, 1915, [Convention date]. Back-pedalling brake and free-wheel arrangements.-In a coaster hub, the driving-member is provided with cams 24 adapted to cooperate with segments 25 in such manner that, in forward-driving, the segments couple the driving-member to the hub, and, on back-pedalling, laterally-acting cam-surfaces 26 on the segments effect the application of the brake. For the drive, the segments are pressed out radially to engage the inner surface of the hub. In applying the brake, the shoulders 56, Fig. 3, of the cams engage the shoulders 57 of the segments, so that the segments are positively turned backwards, and, owing to the en. gagement of the surfaces 26 with corresponding surfaces on a part 45, a non-rotatable conical member 38 is pressed to the left to effect the expansion of the brake ring 40. The construction permits of the machine being wheeled backwards without the brake being applied, and the hub shell 2, being symmetrical, can, if desired, be reversed upon the axle. A washer 60 is arranged between the segments and the bearing-balls 18.

Title: Phenyl cyclohexanes and cyclohexenes
Filed: 1952-05-07
Abstract: The invention comprises compounds of the formul  <FORM:0715545/IV (b)/1> and <FORM:0715545/IV (b)/2> where R and R11 are C1-C5 alkyl X is hydrogen, or C1-C4 alkyl and R1 is hydroxy, methoxy, C1-C4 acyloxy or benzoyloxy.  These are made as follows: a p-methoxy-b -(tertiary amino)-propiophenone hydrohalide is condensed with a 1 - cyano - 1 - alkyl - propanone - 2 in the presence of alkali hydroxide or alkoxide to give a 3 - (p - methoxyphenyl) - 6 - alkyl - 6-cyanocyclohexen - 2 - one - 1 and the latter treated with RMgX to yield a 3-(p-methoxyphenyl) - 1 : 6 - dialkyl - 6 - cyanocyclohexen - 2-ol-1. By dehydration of the product there is obtained 3 - (p - methoxyphenyl) - 1 : 6 - dialkyl - 6 - cyanocyclohexadiene - 1 : 3 and/or 3-(p - methoxyphenyl) - 1 - alkylidene - 6 - alkyl-6 - cyano - cyclohexene - 2.  These isomers on catalytic hydrogenation give either (palladium/acetic acid) 3 - (p - methoxyphenyl)-1 : 6 - dialkyl - 6 - cyanocyclohexane or (platinum/ethyl acetate) 3 - (p - methoxyphenyl)-1 : 6 - dialkyl - 6 - cyano - cyclohexene - 2. Finally hydrolysis with alcoholic potash converts the cyano group to carboxyl and R1 to hydroxyl.  If desired the p-hydroxyl group can then be re-methylated or acylated and the carboxyl group can be esterified.  In an alternative process a carboxylic ester group is present throughout (instead of a cyano group) by using as starting material an a -alkylacetoacetic ester. The ester group may be hydrolysed to a free carboxyl group in the final product.  Examples show the preparation of the following compounds: 3 - (p - methoxyphenyl) - 6 - cyano-1 : 6 - dimethylcyclohexen - 2 - ol - 1, 3 - (p-methoxyphenyl) - 6 - cyano - 1 : 6 - dimethylcyclohexadiene - 1 : 3, 3 - (p - methoxyphenyl)-6 - cyano - 1 : 6 - dimethylcyclohexane, 3 - (p-hydroxyphenyl) - 6 - carboxy - 1 : 6 - dimethylcyclohexane, 3 - (p - hydroxyphenyl) - 6 - carboxy - 1 - ethyl - 6 - methylcyclohexane, 3 - (p-methoxyphenyl) - 6 - cyano - 1 : 6 - dimethylcyclohexene - 2, 3 - (p - hydroxyphenyl) - 6-carboxy - 1 : 6 - dimethylcyclohexene - 2, 3 - (p - hydroxyphenyl) - 6 - carboxy - 1 - ethyl - 6-methylcyclohexene - 2, 3 - (p - methoxyphenyl) - 6 - carboxy - 1 : 6 - dimethylcyclohexane, 3 - (p-methoxyphenyl) - 6 - carboxy - 1 - ethyl - 6-methylcyclohexane, 3 - (p - methoxyphenyl) - 6-carboxy - 1 : 6 - dimethylcyclohexene - 2, 3 - (p - methoxyphenyl) - 6 - carboxy - 1 - ethyl - 6-methylcyclohexene - 2, 3 - (p - hydroxyphenyl) - 6 - carboxy - 1 - n - butyl - 6 - methylcyclohexane, 3 - (p - methoxyphenyl) - 6 - carbethoxy - 6 - ethylcyclohexen - 2 - one - 1, 3 - (p - hydroxyphenyl) - 6 - carboxy - 6 - ethyl - 1-methylcyclohexane, 3 - (p - methoxyphenyl) - 6-carboxy - 1 - ethyl - 6 - isopropylcyclohexane, 3-(p - acetoxyphenyl) - 6 - carboxy - 1 : 6 - dimethylcyclohexane and 3 - (p - hydroxyphenyl)-6 - carbomethoxy - 1 : 6 - dimethylcyclohexane.

Title: Improvements in time alarm devices
IPC: G04F3/02
Filed: 1942-08-20
Abstract: 559,551. Time alarm signals. WOOD, S. Aug. 20, 1942, No. 11733. [Class 118 (ii)] [Also in Group XXXVII] A time alarm device comprises stationary contacts connected in the circuit of an electric bell or other suitable warning-device, and a movable contact mounted on a screw-threaded spindle that revolves at a regulated rate. The movable contact is traversed along the spindle and makes contact with the stationary members to close the circuit after a predetermined time. The screwed shaft c, Fig. 2, is provided with a socket c<SP>1</SP>, which clips on to the rear end a' of the spindle a of the minute hand of a clock in place of the knob which is used for adjusting the hands. The stationary contacts consist of two resilient members g<SP>1</SP>, g<SP>2</SP> carried by a strip of insulating material j which is attached to the back of the clock b by brackets k. The movable contact consists of a disc d of insulating material which screws on to the shaft c and is provided with a metal ring e. The shaft c is rotated once an hour by the clock spindle a, and the disc d travels along the shaft because it is prevented from rotating, by a pivoted rod p that rests in a notch f in the disc. Eventually, the movement of the disc causes the ring e to bridge the controls g<SP>1</SP>, g<SP>2</SP> and complete the circuit of the warning device. In use, the disc f is caused to complete the circuit and is then revolved in the opposite direction a number of turns requisite to complete the circuit after a desired interval. In a modification, the rod p is dispensed with, a weight being provided to prevent the disc c from rotating. In another modification, the spindle c may be connected to the clock spindle by a driving chain or belt so that the device may be mounted alongside the clock. The device may be used as a time-operated means for closing any suitable electric circuit.

Title: Pulse controlled system
IPC: G05F1/56
Filed: 1975-03-20
Abstract: 1508821 Control of D.C. motors GENERAL ELECTRIC CO 20 March 1975 [1 April 1974] 11749/75 Heading H2J Power is applied to a D.C. load from a D.C. source by a pulse controlled system comprising a main switching means connected in series with the load for controlling the current thereto, the switching means being a switch of the controlled semi-conductor type made conductive by a gating signal and made non-conductive by a commutating circuit and the mark-space ratio of conductivity of the switching means determining the voltage across the load; the series combination of a capacitor, inductive means and first unidirectional conducting means connected across the load; second unidirectional conducting means connected in parallel with the inductive means and the first conducting means, the first and second conducting means being poled inversely with respect to each other; and control means for periodically initiating conduction of the main switching means and at least one of the first or second conducting means, the arrangement being such that the capacitor is charged via the first unidirectional conducting means in such a way that the charge on the capacitor is applied via the second undirectional conducting means to the main switching means to provide commutation of the main switching means. In Fig. 1 the load is a D.C. series motor 14 whose armature and field windings 16, 18 are supplied from a battery 10 through a main SCR 24 having a variable mark/space ratio determined by gating control 26, which also controls auxiliary SCR's 32, 34. The former is seriesconnected with capacitor 30 and the secondary winding 36 of a transformer 23 whose primary winding 22 is in series with members 16, 18, 24. When SCR 32 is fired, with or subsequent to SCR 24, capacitor 30 charges from battery 10 until its voltage is sufficient to turn off SCR 32, the capacitor voltage attaining a value greater than that of battery 10 due to the action of transformer 23. Since the positive terminals of members 10, 30 are connected together, the negative capacitor terminal will be negative with respect to that of the battery. This contion is used to turn off SCR 24 when control 26 turns on SCR 34, whose conduction also allows reversal of charge on capacitor 30 and diversion of current from motor 14 to assist commutation of SCR 24. The circuit shown permits periodic charging of the capacitor 30 so that, if it fails to commutate SCR 24, one or more further attempts at commutation can be made subject to a maximum allowable conduction period for SCR 24. In modifications Figs. 2 and 3 (not shown), the transformer is omitted, an inductor (46) is inserted in the capacitor charge circuit and either SCR 34 is replaced by a diode (44), (Fig. 2 wherein the natural resonance of members 30, 46 partly determines the time of commutation), or SCR 32 is replaced by a diode (42).
