Abstract: 903,700. Testing gear-wheels. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 31, 1960 [Sept. 4, 1959], No. 30310/59. Class 106 (2). Apparatus for testing an involute gear-wheel comprises a table 11, mounted to slide in two perpendicular directions by means of balls in grooves 4, 8 and 10, 12, the table having an aperture covered by a translucent plate 15 bearing spaced parallel lines 54. The gear-wheel 50 is supported on its base circle 51 which is held between a surface 21 and a beam 41 so that sliding of beam 41 rotates gearwheel 51 on its base circle. An error in the profile of a tooth flank of gear-wheel 50 will move stylus 62 as gearwheel is rotated and cause movement of lines 54 which are projected on to a screen 61 and viewed relative to fixed datum lines 64, 65. When the stylus 62 is repositioned to contact a further tooth flank another of the lines 54 will be adjacent lines 64 and should bear the same relationship to it if the pitch between the flanks is correct. A spherical ended stylus 78 which is vertically displaceable and fixed to table 11 may be used to detect low spots in the teeth.

Abstract: 1431172 Drive coupling CLARKSON INTERNATIONAL TOOLS Ltd 29 June 1973 [29 June 1972] 30441/72 Heading B3N [Also in Division F2] A drive coupling for rotary cutting tools comprises concentric drive and driven members, with the driven member carrying a tool holder, collet 1, therebeing a coaxial axially movable ring 10 between said members and loaded by a spring 11, the ring is connected to each member by a set of rollers 12 and 9 so that normally the driven member is rotated by the drive member through the ring and the sets of rollers, one set of rollers 12, engage cam slots or grooves 14 in the ring to move the ring axially against spring 11 as the torque load increases, such movement releasing the other set of rollers 9 from driving engagement with its member on excessive torque loading. Preferably there are 3 rollers 12 and 3 rollers 9. The rollers 12 are mounted on pins 14 on a drive sleeve 15. When they move out of their cam slots they engage in slot extensions 17 to hold the members in non-driving positions until reverse rotation is provided. Rollers 9 are on pins 14 on the ring 10 and engage in pockets 8 to transmit drive to sleeve 4 but when ring 10 moves the rollers 9 move into an annular groove 7 in the sleeve thus stopping drive thereto. Sleeve 4 drives spindle 2 via balls 6a. Loading on spring 15 can be altered by sleeve 19.

Abstract: 299,434. Motor Improvements, Inc., (Assignees of Liddell, R. P. F.). Oct. 26, 1927, [Convention date]. Filters having sheet filtering-materials.-In a filter for the lubricating-oil of internal-combustion engines, an envelope 20 of material such as canton flannel is supported on a helix 19. The frame of the element is completed by upper and lower plates 22 and by sleeves 23, 25. The sleeve 23 slides on a central bolt 14, which is screwed at its lower end into the base 10 of the filter casing, and the sleeve 25 fits over a short tube 27 seated in a socket in the base. The. casing comprises the base 10 and a cover 11, which is mainly cylindrical but tapered at the upper end to give an ogee section. The cover is pressed into a groove 12 in the base by a clamping member 16 which has a threaded connection with the bolt 14. The base 10 has an inlet passage 30, and an outlet passage 31 communicating through the tube 27 with the interior of the filtering element. The inlet and outlet passages have a bye-pass connection fitted with a spring-controlled valve 32. The filter element contracts slightly under the pressure of filtration, but downward movement of the upper plate 22 is limited by a shoulder 28 on the bolt 14 and upward movement of the lower plate 22 by a bridge-piece 26 fixed to the plate. and engaging with a rib 29 on the cover 11. In constructing the filter element, the ends 41, Fig. 6, of a strip of filtering material are first stitched together to form a loop, and a loop is stitched up one edge 42. Apertures to receive the sleeves 23, 25 are then cut at either end of the loop and the plates 22, with the sleeves, are placed in position. The helix is fitted within the element to one of the plates 22 and the second edge is sewn up. A cord or wire is finally wound round outside the fabric to draw it into the turns of the helix.

A mathematical theory is developed whereby a parameter R = 2# Flexural Rigidity lateral (compressive) rigidity is derived for the jacketed fibre. The desideratum R > A c  is also derived where A c  is a property of the unjacketed guide = 2#a c /(2#)¢ where a c  = radius of core (of core/sheath waveguide); or radius of waveguide (of graded index waveguide), # = difference of refractive indicies (of core/ sheath waveguide); or is given by the relation n = n 1  [1-#(r/ac)α] governing the change of refractive index (n) with distance from the axis (r) of a graders index guide. The invention may be realized by a thick but soft jacket, Fig. 3; a soft inner jacket surrounded by a thin hard shell, Fig. 4 (not shown); a hard inner jacket with a soft shell, Fig. 5 (not shown); hard fibres (e.g. graphite) longitudinally embedded in a soft jacket, Fig. 6 (not shown).

Abstract: 392,169. Filter wads for cigarettes. MAY, R. F., 9, Manor Road, Potters Bar, Middlesex. Nov. 10, 1931, No. 31115. [Class 130.] Mouthpiece filter tips are formed from narrow strips of paper or other material, which may be corrugated or creped, and are bunched together so as to extend lengthwise of the tip. A continuous strip is led rom a roller 2 beneath vertical rotating knives 3. The resulting strips enter the tubular former 4 in which they are compressed as they are led forward by vertical and horizontal rollers 5 penetrating slots in the tube 4. Lengths of tipping are severed by an axially reciprocating knife 6. After passing through a second tube 4b, the tips enter peripheral openings 19a in a wheel 19 to which intermittent rotation is imparted by a pawlended cam-actuated lever 20. A plunger 22 actuated by another cam ejects the tips into a cigarette tube carrier 27. Instead of being bunched within the tube 4, the lengths of material may be enclosed in a strip of paper forming a continuous rod similar to that produced in the usual continuous-rod cigarettemaking machine.
