Title: Improvements relating to dynamic balancing machines
Inventor: MUNFORD JOHN
IPC: G01M1/04
Filed: 1959-07-29
Abstract: 888,539. Dynamic balancing apparatus. DAWE INSTRUMENTS Ltd. July 15, 1960 [July 29, 1959], No. 26052/59. Class 106 (2). A rotary workpiece being dynamically balanced is carried on a member 4 supported by balls or rollers 6 working in grooves 20 in a base member 1, the grooves extending transversely to the shaft of the workpiece and being curved in a vertical plane, so that movement of the member 4 from its equilibrium position produces a small upward displacement. The shaft of the workpiece is supported in a V-bearing 5 carried on the member 4. Complementary grooves 20 are formed in both the member 4 and the base member 1 on each side of the axis of the shaft. Each groove is fitted with a hardened steel strip 17 and a roller 6 runs between the strips 17. The upper member 4 is fitted with side-plates 8a, 8b to prevent coarse axial movement, and the plate 8b is extended downwards and is coupled to a vibration measuring unit at 3. Pins 10 in the base member 1 co-operate with slots 9 in the upper member to limit its movement. It is stated that the natural frequency of the system depends solely on the radii of the grooves and is unaffected by the size or weight of the workpiece.

Abstract: 402,908. Bicycles. WOOD, A. W., 50, Harold Road, Upper Norwood, London. Sept. 20, 1932, No. 26122. [Classes 136 (i), 136 (ii), and 136 (iii).] In a bicycle of the type propelled wholly or in part by the rider in a semi-recumbent position, the seating-surface for the rider is disposed below a plane passing through the wheel axles, so as to give greater stability. The frame comprises two parallel members a, b bent and joined together at the rear and connected at the front by crossbars 5, c. A shield or body e of plywood &c. is suspended from the frame to form a box-like girder structure reaching nearly to the ground, the lower edge being strengthened by a rib f. A seat g with a sloping back h is supported on the rib. The top may be covered by streamline cowling, leaving only a cockpit for the rider, who may be protected by a light hood. The axle j of the rear wheel k is mounted in members m, n suspended from the frame, and is driven by two freewheel sprockets o, p and reciprocating chains y, which wind on sprocket wheels q, r and are connected by cables x and adjustable collars w to treadle levers s, t suspended from the crossbar 5 and acted on by springs v. The sprocket wheels q, r are on a common shaft, so as to effect the return movements of the treadles. The bicycle is steered by a handle-bar and a front fork 2 mounted in a ball-head 3 supported by the crossbar c and a stay 4. Small auxiliary side wheels are adapted to be lowered to the ground.

Patent GB-481971-A (GB)
Title: Improvements in and relating to the manufacture of zinc oxide, particularly of zinc white pigments
IPC: C01G9/02
Filed: 1936-09-28
Abstract: <PICT:0481971/III/1> In the production of zinc oxide from metallic zinc or metals or alloys containing zinc by burning zinc vapours volatilized from a metallic bath and utilizing the heat of combustion of the vapours to vaporize the zinc, the combustion is periodically interrupted by passing a stream of neutral or reducing gases over the bath, so that without arresting the continuous evolution of vapours the bath is cooled sufficiently to prevent violent boiling or bubbling of the melt.  Thereby volatilization of metals other than zinc present in the melt is largely prevented.  The process may be carried out in a rotary or oscillating furnace a, a grate furnace c being provided for initially heating the charge.  Combustion of the zinc vapours may be effected either by air or carbon dioxide. In the latter case the furnace c may provide both the carbon dioxide needed and carbon monoxide to serve as reducing gas when combustion is to be interrupted, combustion then being effected in a duct g which may be heated to a high temperature.  To facilitate separation of metals other than zinc from the molten bath the furnace may be provided with an annular extension a6 communicating with the furnace proper by openings a8.  Due to external cooling, this extension is cooled to and maintained at a lower temperature than the rest of the furnace, for instance at a temperature between the melting points of zinc and lead, so that impurities which gravitate into it by reason of the slope of the furnace are separated by liquation as well as by the action of differences in specific gravity.  In modifications, the annular extension may be located midway of the length of the furnace, or one may be situated at each end, or it may comprise a helix surrounding the drum.  Specification 312,648, [Class 1 (iii)], is referred to.

Abstract: 229,367. Fortway, R. C., and Goswell Engineering Co., Ltd. Oct. 23, 1923. Grease cartridges for use in grease guns &c. A flexible longitudinally split case 1 of thin sheet metal, cardboard, &c. is provided with end plugs 8, 9 of paper or cardboard which are sealed by dipping into molten paraffin wax or the like, and with an external wrapping 5 of paper or the like furnished with tearing strips 6. The longitudinal edges 3 overlap, as shown in Fig. 3, and may be bevelled One end 2 of the case 1 is flared to facilitate the entry of the plunger 15 of the syringe.
