IPC: B62K27/06
Filed: 1920-08-19
Abstract: 173,011. Minstrel & Rea Cycle Co., Ltd., Griffiths, K. G., and Wesson, F. J. D. Aug. 19, 1920. Springs, mounting bodies on.-A spring suspension for motor-cycle side-cars &c. comprises a cantilever spring of which the ends are connected to the chassis and body respectively, its centre being supported on a bifurcated bracket secured upon the chassis and having an integral cam-surface on which the spring slides between the arms of the bracket. A transverse pin passes through the arms above the spring. As shown, the spring a is pivoted at one end to the body f and at its other end to a link g pivoted to a bracket j on the chassis k. At a point between its ends the spring or its securing-plate b slides on a cam-surface m on a bracket l fixed to the chassis, a pin n preventing the spring from leaving the cam-surface. In a modification, the spring is pivoted directly to the bracket j, the link connection being provided between the body and spring. According to the Provisional Specification, the bracket may be fixed to the body of the side-car &c. and the cam-surface may be replaced by a roller.

Abstract: 1,273,535. Telescopic tower cranes. W. F. VONCK. 20 May, 1969 [21 May, 1968], No. 24141/68. Heading B8B. A folding crane comprises a tower with two sections 11, 12 and a jib 13 supported by a backstay cable in two sections 18, 46. A towerextension cable 40 is reeved around pulleys 31 to 36 and passes to a tower telescoping winch 41 from which it continues around pulleys 42, 44, 47 and back to pulley 44 as back-stay cable section 46. A derrick winch line 48 passes from the pulley 47 over pulley 49 to a derrick winch 45 which may be operated independently to vary the position of the pulley 47 to luff the jib 13. The height of the tower may be altered by operating the winch 41, the cable 40 taken in or paid out compensating the cable section 46 so that the jib 13 maintains its attitude as the tower height is altered.

Title: Improvements in and relating to reaction products of polydienes and sulphur dioxide
IPC: C08C19/20
Filed: 1949-09-23
Abstract: Polydienes are reacted with sulphur dioxide in the presence of a hydroperoxide derived from a hydrocarbon containing at least one aliphatic chain containing not more than three carbon atoms and one or more aromatic nuclei.  The term "polydienes" signifies polymers, having a number of unsaturated carbon-to-carbon bonds and a molecular weight above 5000, derived from dienes such as butadiene, pentadiene, isoprene and chloroprene, alone or with vinyl compounds, e.g. styrene and acrylonitrile, and includes natural rubber, guttapercha and balata.  Specified hydroperoxides are ethylbenzene-, diethylbenzene-, xylene-, triphenylmethyl- and cumene hydroperoxides.  The reaction products may be obtained in the form of threads, fibres, ribbons, films and foils by extruding a solution of the polydiene and hydroperoxide into a solution of sulphur dioxide.  The polydienes may be mixed with low molecular unsaturated compounds, e.g. alkadienes and allyl compounds, as described in Specification 659,083.  The examples describe the reaction of plasticized natural rubber, dissolved in a mixture of benzene and toluene, with sulphur dioxide dissolved in ethanol and water, at a temperature of -5 DEG  C.  The coagulated threads, after washing with ethanol and drying, have a sulphur content of 21 per cent.

Title: Improvements in centrifugal friction couplings

Filed: 1922-09-11
Abstract: 209,456. Hals, J., and Hals & Co., Aktieselskabet, I. M. Sept. 11, 1922. Clutches, friction.- In centrifugal clutches of the kind in which loose blocks carried by the driving-member press against an annular driven member, the blocks are, arranged to have point or line contact with the driving-member, so that they roll or rock into engagement, the contact surfaces of the blocks or the driving-member being radial. There may be any even number of the blocks, 2, Fig. 2, which may be held in place in the driving-member 3 by shoulders 4, 5. To facilitate assembly, the member 3 is formed in two parts 7, 8, Fig. 3. The driven member 1 may be slidden axially for disengagement. As shown in Fig. 4, the line of driving-thrust 13- 13 passes through the mid-point 15 of the friction surface of the block 2. During acceleration, the thrust exercises on the block a clockwise moment, which is later overcome by centrifugal force, so that the block 2 rocks about the point 14 into engagement. The cylindrical or spherical ends may be replaced by pointed contact surfaces co-operating with radial-ended blocks. In a modification, either part may carry rollers. The contacting surfaces of the driven member 1 and the blocks 2 may be cylindrical, spherical, or single or double conical. In Fig. 12, the centrifugal bodies L are shown as balls, of which there may be more than one row, seated in radial-sided pockets in the driving-member A and coacting with cylindrical, conical, or spherical surfaces on the driven member B. The balls L may be replaced by barrel-shaped or double-conical rollers. In another form, Fig. 18, a radial-sided pin 19 on the member A engages rollers 16 or rounded surfaces on a central cavity in the block L. The pin may carry a pointed knob engaging radial sides of the cavity, or an axially-disposed pin may be used. The blocks L may taper towards their ends to reduce their weight, and may have convex, concave, or wedge-shaped inner surfaces, as shown in Fig. 25, the adjacent parts of the member A being correspondingly shaped. The driven member B may constitute a fly-wheel. Specification 180,417 is referred to.

Title: Process for preparing alloys of precious metals capable of being age-hardened
IPC: A47C19/02
Filed: 1930-08-19
Abstract: Alloys capable of substantial age-hardening are made from basic alloys which contain from 60 to nearly 100 per cent of gold or silver or both as the main constituent, and up to 30 per cent of a metal of the platinum group, with or without other precious or non-precious metals such as copper, by the addition to the basic alloy of about 0,02-5 per cent of one or more of the metals iron, nickel, cobalt, and manganese, or about 1-8 per cent of one or more of the metals zinc, cadmium, and chromium, or metals from both these groups.  In the examples given the alloys are age-hardened by heating at about 900 DEG  C., quenching, and annealing at about 550 DEG  C. for varying periods of time.  The Specification as open to inspection under Sect. 91 (3) (a) describes also alloys which contain platinum as the main constituent with subordinate quantities of other metals of the platinum group, and the addition of magnesium as a metal for promoting age-hardening.  This subject-matter does not appear in the Specification as accepted.
