Abstract: 884,778. Levelling staves. HOLMES BROS. (LONDON) Ltd. Sept. 28, 1960 [Oct. 28, 1959], No. 36592/59. Class 97(2). A telescopic levelling, staff has an inner section 2 able to be nested within one or more outer sections 3, 4, each of which outer sections comprises a longitudinally extending member made up of wooden laminae formed and bonded into a U-section and a face member joining the limbs of the U at or near their ends to form an internal space which is D- sectional and dimensioned so that an inner member is a sliding fit therein. The U-sections of the outer sections may be made by stacking wood laminae coated with heat setting adhesive on a flexible sheet and pressing the stacks against a flat bed with a U-former so that the sheet lies between the stack and the bed, pulling the sheet so as to wrap the stack around the former, holding the stack in that position by means of coacting rams on either side of the former and heating the stack in that position by using the former and rams as heating electrodes until the adhesive is set and the stack has taken up a permanent U- shape. The laminae may be mahogany bonded with urea formaldehyde resin. The centre section 2 may be made of D-section but is preferably solid. The front face 8 of the centre section and inset faces 9, 10 of the outer sections are provided with markings for surveying. The markings may be applied directly to the respective faces 8, 9, 10 or they may be applied to strips of material such as plywood or veneer which are secured to the faces.

Title: Improvements relating to the treatment of artificial silk with liquids
IPC: D01D10/04
Filed: 1930-12-04
Abstract: The process of the parent Specification is modified in that instead of artificial silk cakes obtained by the centrifugal process, thread laps obtained by spinning on to bobbins and subsequently removing therefrom are subjected to the liquid treatment.  The thread laps are obtained in a thick layer so that when removed from the bobbins, they behave in the same way as the spun cakes when subjected to the liquid treatment.  Water or other treatment liquid is supplied to the interior of the thread laps carried on a fixed support, the liquid being allowed to flow over the upper edge of each lap so that as a result of the upward flow of liquid, the lap expands upwardly and the layers of thread are loosened; the upward expansion is limited by abutments mounted above the thread laps.  The thread laps are mounted individually on carriers and treated with washing, desulphurizing, bleaching, and other liquids.  Specifications 357,971 and 358,151 are referred to.

Title: Manufacture of shoe stiffener material
IPC: A43B23/08
Filed: 1934-12-31
Abstract: 454,646. Shoe stiffener material. ARDEN BOX TOE CO., Calvin Road, Watertown, Massachusetts, U.S.A. Dec. 31, 1934, No. 37364. Void [Abridged as open to inspection under Sect. 91 of the Acts, July 19, 1935]. [Class 17 (ii)] [See also Group VIII] Material for shoe stiffeners is made by embedding substantially dry, mechanicallypowdered stiffening-agent amenable to gelatinization by a volatile solvent in and between the fibres of a fibrous foundation, and fixing the stiffening agent by treating the foundation with a fixation fluid or liquid binder. The binder employed is preferably a solid which is soluble in the same volatile solvent which is used to gelatinize the powdered stiffening agent on the fibrous foundation. The fibrous foundation may have a pile on both faces, in which case the faces are treated in succession, or the under surface may be comparatively smooth and coated with a suitable sizing material to prevent the passage of the powdered stiffening agent through it. The stiffening agent may be cellulose esters, such as cellulose acetate or cellulose nitrate, powdered shellac or powdered dextrin, suitable volatile solvents such as acetone, ethyl acetate, ethyl alcohol and water, respectively being employed. A solution of ester gum in benzol or other hydrocarbon solvent which does not in itself gelatinize the cellulose acetate is a suitable binder solution when cellulose acetate is used as the stiffening agent. Powder is fed from a hopper 15, to a grooved roll 13 which deposits it upon a sheet 10 of material to be treated and which passes over a vibrating or'tapping instrument 18 to distribute the material over the sheet. Alternatively, the powder may be distributed by a brush. The fabric then passes over a guide roll 20 and between a pair of rolls 21, the upper of which applies a solution of the binder from a tank 22. The fabric is then festooned over a series of rolls 25 to permit the solvent to be evaporated, warm air being used to promote this, if desired. The fabric is then wound on rolls 26 and used for the preparation of box toe or other shoe stiffener blanks with skived margins.

Title: Motor vehicle transmission system
Inventor: WICKMAN AXEL CHARLES
IPC: F16D43/12
Filed: 1962-10-05
Abstract: 1,060,072. Change speed and clutch control. AXEL WICKMAN TRANSMISSIONS Ltd. Sept. 20, 1963 [Oct. 5, 1962], No. 37708/62. Headings F2C, F2D and F2L. In a motor vehicle transmission having a centrifugal clutch or fluid coupling and a change speed gear between an engine and the road wheels, means responsive to gear lever position are provided for preventing the transmission of adequate power to drive the road wheels when an attempt is made to drive the vehicle forward from rest in at least one high gear. The means may prevent engagement of the centrifugal friction clutch or may empty the fluid coupling when the vehicle is started from rest in a ratio other than first or second gear.  In Fig. 1 engagement of a centrifugal clutch having a clutch plate 16 which is normally clamped between a flywheel 11 and presser plate 22 on outward movement of centrifugal masses 26, is prevented when starting from rest in a ratio other than first or second gear by pawls 44 which are moved into the path of the masses 26. The pawls 44 are pivoted at 45 to a plate 46 which is rotatable on, and axially movable with, a sleeve 51 connected to a shift rod 52 of the gear. The pawls 44 are thus moved to the position shown whenever a ratio higher than first or second gear is engaged. During ratio shift whilst the vehicle is moving the engine speed is sufficient to retain the masses 26 in their outward position in which they abut stops 37 and the clutch is disengaged manually through a lever 38, thrust bearing 39 and linkage 40, 41 to move right the mass carrier 25 and permit springs 32 to release the clutch. When the vehicle comes to rest in high gear the masses 26 move inward, the pawls 44 pivoting inward against the bias of springs 53 until the masses are in the innermost position shown whereupon the pawls move to the position shown and prevent clutch re-engagement whilst the vehicle is in high gear. The mass carrier 25 is positioned relative to the casing 17 by springs 30 and the compression of the clutch release springs 32 may be adjusted by nuts 33. In Fig. 6 a fluid coupling 131 is normally maintained full by supplying liquid from a pump 139 to the coupling and through a line 137 to a valve 135 which in the position shown closes a drawn line 136. When the vehicle comes to rest in high gear switches 72, 73 are closed to energize a solenoid 149 which moves right a valve spool 150 to cut the pump supply to line 137 which is opened to vent at 145 whereupon the valve spool 147 moves up and and the coupling is emptied through line 136. When low gear is engaged the switch 72 opens causing the valve spool 150 to move left and permit the coupling to be refilled.
