Title: Improvements in or relating to cot grinding or like machines
Inventor: BRIERLEY THOMAS
IPC: B24B5/35
Filed: 1960-09-16
Abstract: 910,279. Grinding textile machine rollers. CLEGG & MELLOR Ltd. Sept.16, 1960, No. 38664/61. Divided out of 910,278. Class 60. The two cot grinding processes effected sequentially in the two appliances disclosed in Specification 910,278 are carried out in a single appliance whereby the cots C of a roller are held in a first position in which they are ground to a required diameter and concentricity and are then subjected to further grinding in a second position to correct differences in parallelism between the pair of cots on a roller. The lower portion 36 of a composite handle used for gripping the centre of the roller between its pair of cots is slidable on a slideway 332 and terminates in an L- shaped jaw 37, the upper hook-shaped jaw 38 being operable by squeezing together the handle elements 40, 36 to hold the roller, the cots then being brought into contact with a pair of preferably knurled driving rollers 23, the cots being then traversed by the grinding- wheel to complete the first stage. The second stage is effected by withdrawing the member 36 whilst retaining the cot roller in the grip of the jaws 37 and 38 to a position in which the cot roller is " cradled " between pairs of upper and lower positioning and driving rollers, 23, 24, Fig. 4, when the second grinding operation is effected. A quick-release of the cot roller from the gripping device may be made by a downward movement of a handle 442 pivoted within the inverted U-shaped copper handle 40, the underside 44 of the release member bearing on a link member 42 between the handles 36, 40 whereby the jaw 38 is lifted to release the cot roller. The positioning rolls 23, 24 are urged into contact with the cots by springs 27, Fig. 4, inserted between slides 251 on the roll-supporting brackets 26, these springs being compressible by cams 291, 292, carried on a shaft 29 operable by a handle 30. The rolls 23, 24 are driven through clutches 191, 192, 193,194 and intermediate pinions 201, 202 meshing with gears 211 and 221 on the roll spindles. The driving shaft 141 also drives a shaft 15 through gears 161, 171 by which the drive is transmitted to the pairs of rolls on the further side of the central bearing support 28.

Abstract: 361,163. Making composite pipes. FAGERSTA BRUKS AKTIEBOLAG, Fagersta, Sweden. Dec. 23, 1930, No. 38790. Convention date, Sept. 25. [Classes 83 (ii) and 83 (iv).] Rolling tubes ; cores and fillings.-In making hollow drill steels or other hollow metal goods, steel is cast round a lining tube of rust-resisting iron or steel in a chill mould so as to weld it to the tube, and after treatment of the ingot in roughing rolls the bore of the composite billet thus produced is rendered round, central and uniform by drawing or forcing a drift therethrough &c. The billet is then converted into a tube blank by rolling on a mandrel and is subsequently converted into a drill steel &c. by rolling in a finishing mill on a metal or sand core. The lining tube, previous to casting, is provided with a sand core or with a core of metal or alloy, with or without an intermediate layer, such core being removed from the billet prior to rendering the bore uniform ; a metal core is removed from the billet by hammering or pressing, a sand core is removed by dipping the hot billet in water so as to generate steam which blows out the sand.

Title: Packaging temperature monitoring
IPC: G01K5/48
Filed: 1975-09-22
Abstract: 1523156 Temperature history monitor NICOA CORP 22 Sept 1975 [23 Sept 1974] 38860/75 Heading G1D The temperature of a package, e.g. a refrigerated blood bag, may be monitored by attaching thereto a device which includes a temperature sensitive element of the "memory" type. The device includes means for forming the element from a first to a second configuration, and indicator means that indicates the forming of the element into the second configuration and the return thereof from the second. As described, the device comprises fixed and movable discs, relative rotational movement therebetween causing bending of the element. In one embodiment, figures 1 and 3, the element comprises a wire 30 one end of which is fixed in a raised island 24 on a fixed disc 20. Rotation of disc 10 bends the wire, a raised portion 34 of cam 32 pushing the wire until a recess 36 of the cam, which rotates with the disc 10, engages a stop 26. The disc 10 is then returned to its original position, Fig. 3 an indicator 33 then being visible through window 13. Subsequent unbending of the wire to its initial configuration, as shown in dotted lines, allows a second indicator 35 to be visible through window 15.  In a second embodiment, Figs. 5 and 6, (not shown), a raised island (114) forces the wire bending upon relative rotation of the discs (110 and 120) until disengaged by a cam surface (134). No return twist is required, an upraised island (133) being visible through window (113) in the set position, unbending of the wire causing its free end to be visible through a second window (115). In a third embodiment Figs. 7 and 8, (not shown) a single window indicates the forming and return of the wire, which return occurs in a substantially linear relationship of return movement to temperature change over a temperature range of at least 5C.

Abstract: 833,520. Electromechanical vibrating systems. BRONZAVIA. Dec. 21, 1956 [Jan. 18, 1956], No. 38958/56. Class 40 (8). A magnetostrictive apparatus, e.g. an electromechanical filter, comprises a core member of a single homogeneous magnetostrictive material having one or more windings arranged to have an asymmetrical magnetic effect on portions of said member disposed on each side of the neutral flexing surface thereof. A nickel bar 1, having transverse holes 4 in the plane of its neutral surface, is subjected to the permanent magnetic field Ho of magnets 2; end pieces 3 being provided to ensure continuity of the field. Two windings 5 are wound in a figure-of-eight through holes 4 and connected to terminals 6, 7. An alternating current is applied to terminals 6 and an alternating field H is thus superimposed on field Ho and the bar is subjected to flexural vibration. The second winding 5 transduces this vibration and the output is taken from terminals 7. Instead of being of figure-of-eight form the windings may be arranged on one side only of the plane of the neutral surface or on alternate sides. The core member may also have inner sections cut out or be assembled from different pieces of nickel in order to facilitate the winding, Figs. 7 and 8 (not shown), and the asymmetrical magnetic effect may alternatively be produced by using a core of different dimensions on each side of the neutral surface, Fig. 9 (not shown).
