Title: Brushing Tool and Method of Manufacture
IPC: A46D9/02
Filed: 1968-04-18
Abstract: 1,161,959. Rotary brushes. OSBORN MFG. CO. 18 April, 1968 [13 June, 1967], No. 18337/68. Heading A4K. [Also in Division B5] In a rotary wire brush of end, cup or wheel form, the tips of the bristles 10 are located in uniformly distributed indentations, in part 6 of the removable end plate 4 of a mould, formed in the upper part of the space between the members 1, 7, while elastomeric material, filling the mould space, is cured. Plate 4 is assembled with the mould by driving wedge 15 through slot 16, in the head of bolt 13. Shallow slots 19 enable gases to escape and receive any flash produced during curing. A polyurethane elastomer may be formed in the mould by reacting toluene diisocyanate with polyester or polyether, in the presence of a small quantity of water to produce slight foaming, by release of carbon dioxide, formed on cross-linking the polyurethane chains. Foamed epoxy resin or vinyl plastisol may alternatively be used. Uncured natural or synthetic rubbers may be softened by heat, so that they flow into the spaces between the bristles, but not necessarily reaching the hub 8 of the brush and caused to foam, while being cured, by the addition of a blowing compound.

Abstract: 373,816. Steam-engine valves and valve-gear. SALGE & CO. TECHNISCHE GES. W., 35, Budapesterstrasse, Berlin. June 29,1931, No. 18784. Convention date, June 27, 1930. [Class 122 (ii).] The inlet and exhaust are controlled by separate double-beat lift valves arranged one behind the other so that one valve seat of each valve is arranged on a common partition between two steam channels. Two pairs of valves are actuated through levers carrying rollers by a common oscillating cam. The cam may be made in segments which may be independently adjusted for control purposes, or the levers may be adjusted relative to their fulcra, or the fulcra may be adjusted. The inlet and exhaust valves 1, 2 are arranged coaxially, one behind the other, in a separate casing 3. The partition 4 carries two seats in the same or in different planes. The inlet valve 1 enters the hollow space of the exhaust valve. The pairs of valves at each cylinder end are controlled by a single cam. The valves have hollow spindles housing push rods 14, 15. The exhaust-valve spindle carries a cap 13 acted upon by a spring 12. The contacting ends of rods 14, 15 are cut-off semicircularly, slide on one another, and have collars bearing on the spindles 10, 9 respectively. A spring 17 holds the inlet valve down. The valves move independently. A modified construction of push-rods and sleeve is described. The valves are actuated by an oscillating cam made in four segments 19, 21. The segments 19 control the valves 1 through levers 20 ; the segments 21 similarly control the valves 2. The levers 20 are forked and acts on the spindles 9 ; the levers 22 act on the rods 14, or in a modification act on the exhaust-valve spindles. The rocker levers 22 have adjustable fulcra comprising arcs struck from the rollers 24 respectively. The cam segments are arranged on a hub 30 mounted on the pin 8, Figs. 6 and 8. The segments are angularly moved by means of eccentrics 34 and slots 33. The eccentrics are adjusted by axially-movable pins 35 with helical grooves. A nut 40 screwed on the end of the pin 8 can, through a key 42, adjust either pin while the engine is running. With an undivided cam, the control may be adjusted by rotating the axes of the levers 20, 22 around the centre of the cam. The cams of multiple-cylinder engines may be connected by a' rocker-lever system. The Specification as open to inspection under Sect. 91 .(3) (a) states that the divided control cam may operate separately-arranged inlet and exhaust valves. This subject-matter does not appear in the Specification as accepted.

Filed: 1960-05-27
Abstract: 950,319. Preparing samples for spectral analysis. MANUFACTURE BELGE DE LAMPES ET DE MATERIEL ELECTRONIQUE. May 27, 1960 [May 27, 1959; May 24, 1960], No. 18860/60. Heading G2J. Samples for spectral analysis of a solid metal are prepared by taking fragments from a metal body and fusing them together to form a specimen which is then pressed into a cavity formed in a metallic supporting block, the shape and mass of which are like those of a conventional sample. In an example, discs of metal are cut from a plate to be analysed and placed in crucibles secured in a water-cooled piece of copper in a furnace. An electron arc is struck between the samples to be fused and a second electrode of tungsten. During this melting a vacuum is created in the furnace and pure argon is then admitted until a pressure of 400 mm. Hg. is reached. The samples are then withdrawn from the furnace and allowed to solidify before mounting in a metallic support having in its upper surface a cavity in which a sample is pressed. The sample in the cavity can then be subjected to spectroscopic analysis.
