Abstract: 189,202. Welin, A. Aug. 22, 1921, Winches; driving- gear; brakes; regulating and control-transmitting gear.-Winches of the type described in Specification 2811/11, in which a drum shaft is mounted in eccentric bearings so that it can be moved alternatively to engage friction driving-gear or a fixed brake surface, are modified by interposing toothed gearing between the operating handle and the drum shaft, and bv mounting the brake-block resiliently so that the drum can be moved sufficiently past the " hard on " braking position for the selfsustaining pawl to be relieved from the strain of the load, thus facilitating disengagement of the pawl for lowering purposes. Fig. 2 shows the gearing, comprising a crank D on the drum shaft carrying a pinion F and an operating hand-wheel H. Rotation of the hand-wheel moves the pinion and a fixed toothed sector G, and thus moves the crank to rotate the drum shaft and its attached eccentric bearings B.

Title: Monoazo dyestuffs and process for their manufacture
IPC: C09B29/08
Filed: 1952-09-04
Abstract: The invention comprises monoazo dyestuffs of the formula <FORM:0722474/IV (c)/1> where R is a benzene or naphthalene residue which may be substituted by chlorine, bromine, fluorine, alkyl, fluoroalkyl or further alkylsulphonyl groups, R1 is a benzene nucleus which is free from halogen substituents but may be alkyl-substituted meta to the amino group, and R11 is alkyl or hydroxyalkyl.  They are made by coupling diazotized alkyl-SO2-R-NH2 with the appropriate tertiary amine and dye cellulose acetate, polyamide and polyester fibres in fast yellow or orange shades.  Examples show the production of the following dyestuffs: 2-chloro - 4 - methyl - sulphonyl - aniline --> N - hydroxyethyl - N - cyanoethyl - aniline, 4 - bromo - 2 - methylsulphonyl - aniline --> N - hydroxyethyl - N - cyanoethyl - m - toluidine, 2 : 4 - di - (methylsulphonyl) - aniline --> N - hydroxyethyl - N - cyanoethyl - aniline or m - toluidine, 4- or 5 - methylsulphonyl - a  - naphthylamine --> N - hydroxyethyl - N - cyanoethyl - aniline and 2 - bromo - 4 - methyl - sulphonyl - a  - naphthylamine --> N - hydroxyethyl - N - cyanoethyl - aniline. Diazotization is carried out with nitrosylsulphuric acid.  In further examples, (1) acetate rayon is dyed with the first-mentioned dyestuff in a soap bath, the dyestuff being dispersed with Turkey red oil or other surface active agent, preferably also with an inorganic salt; (2) prints are obtained on acetate rayon and polyamide with the same dyestuff pasted with diethylene glycol and gum arabic.  Other components are specified in which R11 may be methyl, ethyl or hydroxypropyl and the cyanoalkyl group may be cyanomethyl.

Title: Improvements in or relating to electric control switches
IPC: H01H21/00
Filed: 1930-07-24
Abstract: 354,989. Snap-action switches; actuating controllers electromagnetically. EVANS, C. T., 12th Street, Milwaukee, Wisconsin, U.S.A. July 24, 1930, No. 22378. Convention date, Oct. 28, 1929. [Classes 38 (iii) and 38 (v).] A switch, particularly applicable for controlling motors, comprises a movable contact-member permanently connected to a terminal, and an operating member, a continuous unidirectional movement of which causes the movable contact first to engage two stationary contacts, then to remain stationary for a period, and finally to disengage one of the stationary contacts. With the switchoperating lever 20 in the position shown in Figs. 1 and 2, the switch is in its " off " position and the movable contact 1, which is permanently connected to a fixed contact 2 by a spring 14, Fig. 4, is in engagement with a fixed contact 3. By rotating the lever 20 to the position shown in Fig. 4, an operating-lever 17 attached to the spindle carrying the lever 20 is rotated to allow the spring 14 to lift the left-hand end of the contact-member 1 against a fixed contact 4, the other end of the contact 1 being maintained in contact with the fixed contact 3 by the tension of a spring 21 connecting the operating member 17 with a similar but freely-mounted member 18. By a further movement of the member 20 the spring 21 is carried across the centre of the switch spindle 16 and the two operating-members 17, 18 are pulled together, the latter releasing the right-hand end of the contact 1 and allowing the spring 14 to lift it from the contact 3. By rotating the lever 20 two steps in the reverse direction similar reverse movements are given to the operating members 17, 18 to depress first the left-hand end of contact 1, and then the right-hand end with a snap-action. In Fig. 7 (not shown) the switch is connected with an electromagnetic relay controlling a motor circuit. When the switch is operated as described, the relay is first energized directly through the switch and then through the switch and auxiliary contacts on the relay.

Wheel-guards, obstruction-removers, and safety appliances.-A safety-guard for a vehicle comprises a pair of independent impact-members of T-shape, each member having the leg of the T in the form of two spring arms straddling and secured to a side-bar of the chassis and the head of the T extending symmetrically on opposite sides of the plane of the side-bar, the adjacent ends of the impact-members closely approaching the mid-plane of the chassis. Shocks to the guards are conveyed to the side-bars through a thrust-block, and means are provided for adjusting the height of the guard. Two impact-members 16, 17 are secured to the chassis side-bars 10, 11 by the spring bolts 14, 15 respectively and have their inner ends extended rearwardly and supported by a strut 32 which is adjustable along the length of the side-bar 10, 11 to enable the height of the front of the impact-member to be varied. The impact-members 16, 17 may be braced together by a tie bar clipped to the centre of each curved portion 18; by one which is clipped to the inside portion 19 of the members; or by clips which connect the two midplane loops of the impact-members. The impact-member may be disconnected without entirely withdrawing the spring bolt through the agency of a slot 25 on the arm of the member which receives the bolt head. The spring bolt 14 is relieved of thrust by means of a block attached by bolts to, and between, the side arms 21, 22 and which may bear directly on to the end of the chassis side-bar or which carries a screwed bolt, the end of which bears against the end of the side-bar.

Patent GB-361944-A (GB)
Title: Improvements in the manufacture and production of hydrocarbons of low boiling point
IPC: C07C2/00
Filed: 1930-07-25
Abstract: Liquid hydrocarbons of low boiling point, especially mono-nuclear aromatic hydrocarbons, are obtained by subjecting gaseous homologues of methane, if desired with an admixture of unsaturated hydrocarbons, at any pressure to a heat treatment at 500-950 DEG  C. in at least two stages at successively increasing temperatures in such a manner that in each single stage only part of the portion of the gaseous homologues of methane which would react in a one stage treatment is converted into liquid hydrocarbons, which are separated after each stage from the unconverted materials.  The heating may be external or in Cowper ovens or by heating bodies arranged in a manner which allows of a short heating duration.  The process may be carried out in the absence or in the presence of catalysts, such as graphite, coke or silicon.  The gases may be passed through two or more reaction vessels in series or recirculated through the same reaction vessel.  Examples are given of the treatment of mixtures of homologues of methane with unsaturated hydrocarbons by recirculation through a single porcelain tube with increase of temperature from 850-950 DEG  C., and through three porcelain tubes filled with pieces of silicon and heated to 800 DEG , 850 DEG  and 900 DEG  C. respectively.  The olefines formed in the first stage may be concentrated before conversion to aromatic hydrocarbons in a second stage.
