Abstract: 108,562. Foster, J. T. Sept. 12, 1916. Race games, mechanical.-In apparatus for playing a race game,.the runners A, Fig. V, are connected by carriers O passing through slots C - - C<6>, Fig. II, in the cover N of a box Q to endless driving-belts 8 passing over pulleys D - - D<6> loose on shafts E. Transverse shafts P - - P<6>, which are telescopic so that they can be moved slightly endways by means of levers G pivoted to the side of the box, carry loose pulleys I - - I<6> of different diameters. The shafts P are driven by belts from the hand-operated driving-shaft J, Fig. VI, and the pulleys D - - D<6> are driven by belts from the pulleys I - - I<6>. When a lever G is pushed in, the pulleys I - - I<6> on the corresponding shaft are pressed together and become the drivens of the runners A. To ensure release of the pulleys I - - 1<6> when a lever G is released, a pivoted hammer T below the shaft P is caused to impart a blow to the shaft by rods V operated by the lever G.

Filed: 1927-05-14
Abstract: 295,645. Carpmael, W., (I, G. Farbenindustrie Akt.-Ges.). May 14, 1927. Anthraquinoneacridones.-Diphthalylacridones are converted into new vat dyes by treating them with nitrating agents, e.g. concentrated nitric acid or a mixture of nitric and sulphuric acids. The products may be reduced to the amino derivatives; both the nitro and amino compounds dye cotton from the vat, usually in greyish-blue shades. The aminoderivatives can also be acylated, yielding grey vat dyes of particularly good fastness properties. In examples, (1) 3 : 4 : 5 : 6-diphthalylacridone is heated with nitric acid, the nitroacridone separates out on cooling and may be reduced to the aminoacridone by means of aqueous sodium hydrosulphite solution, advantageously in the presence of alcohol; on treating the amino compound with benzoyl chloride, in nitrobenzene solution a dyestuff is obtained which dyes cotton from the vat in very fast violet-grey shades, and (2) 1 : 2 : 5 : 6- diphthalylacridone (obtainable by condensing 1- chlorawthraquinone-2-carboyic acid with 2- aminoanthraquinone and subsequently closing the ring by means of sulphuric acid) is nitrated by means of a mixture of nitric, and sulphuric acids and the product is reduced to the, amino' compound by reduction with alkaline hydrosulphite and subsequent blowing out of the vat with air; the benzoyl derivative dyes cotton from the vat, in fast olive-green shades. Specification 894/11 and German Specification 268,219 are referred to.

Abstract: 132,477. Welter, J. F. May 23, 1919. Foot and leg deformity, treating; splints; limbs, artificial.-An apparatus for assisting lame and paralysed persons to walk, which can also be applied to artificial legs, comprises a padded thigh socket 1 secured in position by lacing, as shown at 2. A separate cushion may be placed between the lacing-flaps and the surface of the limb. A second open socket 5 engages the lower leg and slides axially thereon during the process of walking. A pair of antifriction rollers 9 facilitate this axial movement. The two sockets are connected by one or more bent springs positioned so that the lower leg is forced forward automatically to the angle shown in Fig. 1, when it is lifted from the ground. The appliance thus relieves the wearer automatically from the exertion of making a forward step. The illustrated construction shows two bent springs 7, 8 and one example of an additional spring 11 which can be engaged between the pins 13, 14 to strengthen the spring action when necessary.

[Also in Division F4] A heat radiator panel comprises the assembly of two steel sheets A and B which are blanked and pressed out to form therebetween two horizontal longitudinal manifolds a and b interconnected by a series of vertical passageways 4, the manifold a being connected to a supply pipe of a heating circuit and the manifold b to a return pipe. As shown the manifolds are formed in the back panel B which is also formed with vertical grooves 10, separated by flat portions 17, and with inlet and outlet apertures to which screw-threaded bushings 1 and 2 are welded. The passageways 4 in panel A are separated by plane portions 5 which are spot welded to the portions 17, Fig. 2 (not shown). The mating edges of the sheets are seam welded together and the corners 18 cropped round. Mounting tabs 19 are welded to two successive ribs formed by the grooves 10. Since the grooves 10 are too deep to permit their formation in one press operation without splitting or bursting of the metal they may be formed in successive press operations by three punches of successively increasing depth.

Abstract: 782,092. Electric measuring systems. ZAHNRADFABRIK FRIEDRICHSHAFEN AKT.- GES. May 23, 1955, No. 13443/56. Divided out of 782,091, [Group XXXVI]. Class 40 (1). Apparatus for measuring the torque transmitted by a shaft comprises two pairs of strain gauge resistors fixed to the shaft so that the twist of the shaft produced by the torque transmission causes the resistance of one pair of strain gauges to increase and that of the other to decrease, the change in resistance being determined by the portable bridge described in Specification 782,091. The bridge is energized by a generator G (Fig. 5), driven by a batteryenergized motor M. Two of the arms of the bridge constitute the test strain gauges 30, 31 and the other two 12, 12<SP>1</SP> are included in the portable apparatus, which also includes the 3-stage amplifier for the bridge unbalance voltage, the amplified output being demodulated and fed to. a recording oscillograph. An initial standard unbalance is produced by introducing a resistor 35, 36 or 37 in parallel with one arm 12 of the bridge, the selecting switch 28 being coupled with a bridge voltage selecting key 27, to produce a standard deflection on the oscillograph from which the test deflections during torque transmission may be gauged.

Switches, quick-action; switchboards.-In a switch of the type having a series of individuallyoperable switch elements carried by a common spindle by means of which all the switches may be operated, the individually operable switches each comprises a two-armed lever, one arm d of which serves as the handle and the other serves as the contact member to engage with the fixed contact l on the base, the two arms making such an angle with one another that, by reversing the position of a lever on the spindle c, what was formerly a contact position of the lever becomes a ' switch-open ' position. The spindle, which carries all the movable switch mechanism, is mounted on the removable cover a of the base b, and the individual operating arms pass through a slot in the cover. A circular enlargement k at the pivot of the switch arms serves to cover the slot in all positions of the operating arms. Pins g projecting diametrically through the master spindle engage pins h on the individual switch arms and provide for common operation. A quick action is imparted to the switch members by the engagement of the pins h with a bent spring i. The spindle may carry also a cam-shaped contact e, Fig. 2, which co-operates with a spring contact m to give a signal when all the switches are in the ' on ' or ' off ' position and to retain the master spindle in either of its two positions. The spindle may serve as a common bus-bar and the cover may carry current.

Filed: 1916-09-25
Abstract: 109,836. Heyl, G. E. Sept. 25, 1916. Tar oils, purifying.-Naphthalene is removed from coal-tar oils and other hydrocarbons by treating them first with dilute caustid alkali solution, and cooling to separate the bulk of the naphthalene; and then with solid or concentrated caustic alkali, sufficient to neutralize the tar acids remaining in the oil, either before or during distillation. The treatment before distillation may be carried out at ordinary or raised temperature, and the naphthalene separates on cooling or standing. A small quantity of concentrated alkali is added to the oil during distillation to cause retention in the still of darkcoloured substances. In the treatment during distillation, the naphthalene separates in the condenser.
