Title: Milling paring device for the skin
IPC: A61H7/00
Filed: 1930-10-15
Abstract: 367,771. Massage and skin treating apparatus. HOFFMANN, G., 62, Albrecht. strasse, S³dende, Berlin. Oct. 15, 1930, No. 30832. [Class 81 (ii).] A rapidly rotating paring device for the human skin has paring means, such as bristles, hairs, or fibres, which are mounted on a support so that they are inoperative in the proximity of the rotational axis and their ends execute a straight line or a circle of at least 2 mm. diameter on the skin, and which revolve at at least 300 revolutions per minute and move over the skin at a rate of 0À2 to 10 m. per second. Means are also provided for imparting a vibration to the parer. An electric motor 1 drives a skin parer 10 through reduction gear comprising a pinion 4 and a cap 6 of moulded insulating material rotatable on a journal 5. A spring 8 holds the cap 6 and pinion 4 out of engagement except when the parer 10 is pressed in the direction of the arrow 9. The parer is interchangeably mounted on the cap 6 and may be of roller form or, as shown in Figs. 3 and 4, flat or mushroom shaped. The centre 22 is left free from bristles, or these are cut shorter for a distance of at least 1 mm. from the centre. In the mushroom construction, the bristles are arranged obliquely near the centre. A handle 16 for supporting the device is made integral with a screen 15 and carries a spring 18 fitted with a braking device 20 whereby the speed can be reduced to within the desired limits before the parer is applied to the skin. Since the armature is not exactly balanced but always exhibits a slight unbalanced mass defect, a vibration will be transmitted to the parer if this is rigidly connected to said armature. An unbalanced weight 3 may be fitted if desired. The parer may itself be made so as to produce a vibration, for example by fitting an unbalanced weight, or making it asymmetrical relative to its rotational axis. The parer may be connected with the driving means through resilient means 13, Figs. 1 and 6, so that it can be forced out of its central position, for example by the process of cutting, to produce a vibration. In a modification, the parer is driven by a motor through a flexible shaft running into a handle and connected to a shaft on which the parer is mounted. Reference has been directed by the Comptroller to Specifications 2201/02, [Class 81, Medicine &c.], 27756/04, [Class 131, Toilet &c.], 20449/05, 20606/06, [both in Class 81, Medicine &c.], and 302,219, [Class 19, Brushing &c.].

Abstract: 661,745. Knife edge bearings. PEUKER, F., and JOKSCH, R. Dec. 5, 1949, No. 31214/49. Class 12 (i). A rolling friction knifeedge rocker bearing, as for weighing machines and other apparatus requiring accurate and sensitive fulcrums, comprises a knife edge member consisting of two steel plates 9, 10 having axially displaced extending parts 11, 12 whose edges 13, 14, forming the bearing axis, engage alternatively inclined faces 15, 16 of two or more bearing members 5, 6 rocking about parallel and oppositely disposed edges 7 thereof located between lateral portions 3, 4 and a base portion 2 of a supporting member 1.

In another modification, the bearing is inverted, a plate-like cage retaining the bearing members. In modifications of the knife edge, the bottom surface of the plates 9, 10 may be inclined instead of being horizontal, or it may comprise a single continuous V-shaped edge contacting both bearing members.

Title: An improved electrical quick acting step regulator
Filed: 1920-11-04
Abstract: 170,207. Dick, E. Nov. 4, 1920. Regulating-switches. - In electric resistance regulators, a comb-like member adapted to move in rolling or abutting contact with a stationary row of rheostat contacts, is composed of a number of wire or thin sheet metal loops 7, Fig. 3, attached along a bar 8, Fig. 1. The sizes and dispositions are such that the upper portions of the loop lie along a curve and a correspondingly curved bar 27, rigidly attached to the bar 8 maintains the regularity of the curve against irregular influences such as springiness of the wire. The stationary rheostat contacts lie along a path 1, and are recessed along the middle so as to clear the bar 27. One end of the bar 8 turns on a pivot 9 which itself rocks about a stationary shaft 11, the other end of the bar being actuated as shown by a solenoid core, or otherwise. In a modification, the loops are open at one side, as shown at 7, Fig. 5, the supporting-bar 8 is stationary, and the curved bar 27 is rocked about a swinging pivot so as to allow the loops to rise successively under spring tension. The resistances to be controlled may, in this modification, be connected to successive loops, interspersed with insulation, and the stationary track 1 may be of continuous metal. The invention is applicable for use as a voltage regulator, for dynamos. Instead of a solenoid, the regulation may be actuated by moving coil, induction disc, or thermal devices.

Abstract: Olefinically-unsaturated hydrocarbons are polymerized in the presence of a product prepared from (a) a metal of Groups 1, 2 or 3, (b) the halide of a metal other than vanadium of Groups IVa, Va or VIa, and (c) an aluminium halide by reacting at elevated temperature, the compound (a) with the compound (b) or with the compound (c) at an elevated temperature and then adding the third ingredient, or with both (b) and (c).  The reaction may be effected in the presence of a hydrocarbon solvent.  Olefinically - unsaturated hydrocarbons mentioned are ethylene, propylene, butylene, isobutylene, butadiene, isoprene, styrene, and alkyl substituted sytrenes.  The metal (a) may be aluminium, magnesium, sodium or zinc, or alloys thereof, and it may be in the form of powder, granules, wire, sheets, foils or as a colloidal dispersion.  Suitable halides (b) are titanium tri- or tetrachloride, titanium tetrabromide, chromium trichloride, chromyl chloride (CrO2Cl2) and halides of zirconium, hafnium, niobium, tantalum, molybdenum, tungsten, or uranium.  The polymerization may be carried in the presence of solvents or diluents such as pentane, octane, gasoline, cyclohexane, tetra or decahydronaphthalene, benzene, toluene, xylene, ethylbenzene, or naphthalene.  The polymer may be purified by washing with organic solvents such as alcohols and ethers in which inorganic or organic acids may be present.  Large pieces of residual metal may be separated mechanically from the polymer.  The polymers may be used for the manufacture of foils, films and threads.
