Title: Improvements in or relating to screw propellers
IPC: B64C11/06
Filed: 1930-03-18
Abstract: 345,091. Screw propellers. WHITE, A. E., 5, Quality Court, Chancery Lane, London.-(Hamilton Standard Propeller Corporation ; 221, West 7th Avenue, West Homestead, Pennsylvania, U.S.A.) March 18, 1930, No. 8707. [Class 114.] A screw propeller with detachable adjustable blades is formed with the base of each blade having a solid flange-like annular bearing or abutment adapted to seat on a corresponding annular face on the hub to take up stresses imparted to the blade under temporary heavy load or blade flutter. The blades 12 are mounted on supports 11 on the boss and have roller bearings 16, 27 and 15 which take the normal stresses. The base of the sleeve 18 of each blade has an annular flange member 28 adapted to rest on a seat 29 on a flange 31 on the hub 10. The periphery of a bearing 28 is notched to form lugs to take a spanner when as. sembling the blades. The flanges 31 are reinforced by ribs 32 extending across the hub. These ribs afford guides 33 for sliding members 34 which have a pivotal connection through yokes 35 with lugs 36 on collars 37 freed to the blades whereby pitch adjustment is effected. In a modified form where wooden blades are employed the blades are held by clamps which may be adjusted for securing static balance of the propeller.

Patent GB-1065952-A (GB)
Title: Improvements in and relating to looms
IPC: D03C1/36
Filed: 1964-04-11
Abstract: Two loom parts, which would normally be in contact with each other over their paths of movement, are separated from each other during that part of their movement wherein their mutual contact might result in the transference from one part to the other of an undesirable force which would impede the correct operation of the loom or unnecessarily operate a stop motion thereon.  In Figs. 3 and 4 (not shown) lifter needles (34) and reading needles (28) are moved to the left by a cam operated rod (55), during stepping of the card cylinder (65), and are spring loaded so that the needles (28) return with the rod (55) to read the paper pattern (32).  Due to the uneven operation of the rod (55) it sometimes happens that the knife (38) raises the lifter needles (34) before all of the needles (28) have read the pattern and incorrect shedding results. To obviate this the cam (58), moving the rod (55), is given a steep fall so that contact is broken between the rod (55) and the lifters (34) which return solely under the action of the springs (67) to more accurately read the pattern. In Figure 6 (not shown) a weft selector segment (71) is locked in position by a roller (103) mounted on a arm (104), which is pivoted on a stop rod (114), and is rocked by a cam (109).  As the lever (104) is pivoted clockwise by the cam (109) the segment may be incorrectly positioned by cylinders (81), the roller (103) cannot then enter a slot (102) and the stop rod (114) is moved to the left to stop the loom.  It sometimes happens that, on the withdrawal movement of the roller (103) from the segment (71) the action of the cylinders (81) on the segment causes it to force the roller out of a slot (102) before the moment it would normally be withdrawn by the cam (109) and thus the stop rod (114) is unnecessarily moved and the loom is stopped.  To obviate this the cam (109) is given a steep fall so that the roller (103) is more rapidly withdrawn from the slot (102) before the cylinders (81) act on the segment (71).

Title: Improvements in and relating to forms for use as shuttering in constructional work in concrete
IPC: E04G9/06
Filed: 1946-03-21
Abstract: 600,543. Casting concrete constructions. HUISH, H. C. March 21, 1946, No. 8829. [Class 20(ii)] Relates to shuttering for concrete construction having curved contours, and consists in a form comprising (i) a flexible metal sheet 1 to the back of which are secured, e.g. by welding, stiffeners 2, 3, 8; (ii) bars 11, which are either flexible or are stiff and of pre-formed curvature, secured across the stiffeners to allow relative transverse movement between the bars and some of the stiffeners, e.g. by screws 12 in slots 13, and (iii) material 14 flexible in one direction, e.g. corrugated sheet metal, disposed between the bars 11 and the sheet 1, which are spaced apart by the stiffeners. The stiffener 2 at one edge is of channel section facing outwards, and the stiffener 3 at the opposite edge has a projection (or projections) adapted to nest in a corresponding stiffener 2 of an adjacent form, the construction being similar to that described in Specification 600,542. The corrugated sheets 14 may be arranged so that a stiffener 8 lies within a corrugation of each sheet, which is retained by a bolt 12. The edges of separate sheets may lie at the sides of other stiffeners 8. The ends of the bars 11, instead of being slotted, may be forked, Fig. 8, and the surface of the bar-ends, whether forked or slotted, may be provided with serrations 16 for engagement by a correspondingly serrated washer 17 beneath the head of the bolt. Alternatively to the slots 13, the bars 11 may be passed through hooks or eyes fixed, preferably by bolting, to the stiffeners 8, and the location of the hooks or eyes may be varied relatively to the length of the stiffeners by providing a plurality of bolt holes. For narrow forms the stiffeners 8 may be omitted. The form may be used flat i.e. with straight bars 11. A plurality of forms may be connected by any convenient means, e.g. the clamps described in Specification 600,544, [Group XXIII], and the forms may be used in conjunction with those described in Specification 600,542 to produce curved surfaces merging into flat surfaces.

Title: Improved mechanism for raising and lowering and fixing windows of vehicles
IPC: E05F11/38
Filed: 1938-03-23
Abstract: 512,925. Vehicle windows. BROOK, E. J. L. March 23, 1938, No. 8856. [Class 20 (iii)] Mechanism for raising and lowering vehicle windows comprises a pivoted sash-supporting arm 1 which is held in any position of adjust-, ment by a friction clutch comprising arms 8, 9 adapted to engage with a fixed arcuate member 4. The arrangement is such that the rotation of the operating handle in either direction serves first to release the clutch and subsequently to rotate the supporting arm. The supporting arm shown comprises two links 7, 25, pivoted to a pair of supporting brackets 5. The arms 8, 9, are pivoted to the link 7 and carry lugs 10, 11 which are urged by a spring 13 into frictional contact with the member 4. A disc 18 secured to the shaft of the operating handle is formed with two projections adapted to co-act with a. lug 28 on the link 7 and with a clutch releasing member 14. Upon rotating the handle the member 14 is first depressed and by means of inclined surfaces 15, 16, serves to separate the arms 8, 9, thus releasing the lugs 10, 11 from the member 4. Continued rotation of the handle effects the movement of the supporting arm. When the handle is released the member 14 is returned by a spring to its initial position and the clutch becomes operative. The sash is balanced by a spring 19 one end of which is anchored to the arm 1 and the other to a pivoted link 21 carrying a roller 23 engaging with the link 25. In modifications compression springs or torsional springs connected to the link 21 are employed.

Patent GB-750614-A (GB)
Title: Improvements in ageing alkali cellulose in the manufacture of viscose
IPC: C08B1/08
Filed: 1953-03-31
Abstract: In the production of viscose, alkali cellulose is obtained from a cellulose pulp containing over 88 per cent of alpha-cellulose, and the ageing is carried out in the presence of a compound of cobalt in an amount which, in the case of alkali cellulose from cellulose pulp containing over 91 per cent of alpha cellulose, corresponds to less than 10 parts of cobalt per million by weight based on the bone dry weight of the cellulose, or which, in the case of alkali cellulose from pulp containing 88-91 per cent of alpha cellulose and preferably also in the case of that from pulp containing over 91 per cent of alpha cellulose corresponds to an amount of cobalt falling within the shaded area and along the ordinate of the alpha cellulose content of the cellulose pulp as shown in the graph.  The cobalt compound may be added to the pulp or to the caustic soda used in the preparation of the alkali cellulose, or it may be added to a slurry of the cellulose and the caustic soda.  A watersoluble compound such as cobaltous sulphate, nitrate, or chloride may be used.  A dye may be added to the treating solution containing the cobalt compound so as to facilitate identification of the treated pulp.  The presence of the cobalt compound reduces the time necessary for effecting the desired ageing of the cellulose.  In an example, a sheet of purified wood pulp containing an alpha cellulose content of 88 per cent is sprayed while entering the drier of the pulp <PICT:0750614/IV(a)/1> machine with a solution of cobaltous sulphate so as to introduce 2 parts per million of cobalt based on the bone dry weight of the pulp.  The pulp is steeped in caustic soda solution for 30 minutes at 30 DEG  C. Sheets of the alkali cellulose so obtained are pressed and shredded and the crumbs are aged for 15 hours at 30 DEG  C.  The alkali cellulose is then xanthated and converted into viscose which is ripened for 24 hours at 20 DEG  C. until it has a salt-point of 7.5. In another example a cellulose pulp of 99.3 per cent alpha cellulose content is treated to contain 0.2 parts per million of added cobalt. The pulp is converted into alkali cellulose which is aged for 8 hours at 30 DEG  C. and then converted into viscose suitable for producing rayon for making tyre cords. Without the addition of cobalt the ageing time would be 24 hours.

Title: Method of producing multi-colour photographic and cinematographic images and more particularly sound and picture films
IPC: G03C7/24
Filed: 1936-03-26
Abstract: 472,644. Colour photography. GASPAR, B. March 26, 1936, No. 8999. Drawings to Specification. [Class 98 (ii)] Multi-colour photographic and kinematograph pictures are produced on material consisting of a set of differently dyed and sensitized layers onto which the different colour separation records are printed, in conjunction with a layer dye black, blackish, or grey into which a key print and /or a sound record is printed, simultaneously or otherwise, all the layers being carried on a single support and the resulting silver images being converted into dye images. The supplementary layer is sensitized for a region to which one or more of the layers is sensitive or to a region outside the range of sensitivity of the other layers, and may be printed from the same master image as one of the other layers or an independent master image. The sound record may be copied into the other layers in addition. If the sound record is to be confined to the supplementary layer, this may be sensitized for infra-red and the sound track area in the other layers exposed to light from which the infra-red rays have been removed, e.g. with a prussian blue or . naphthothiotricarbocyanine methyl iodide filter. In examples, layers are used (1) dyed yellow with chrysophenine and green sensitive, dyed purple with diamine rose G and red sensitive, dyed blue with diamine pure blue and sensitized for infra-red, and dyed grey with diazine black A extra or buffalo black AD and panchromatically sensitized, (2) dyed blue with diamine pure blue and not specially sensitized for colour, dyed yellow with chrysophenine G and green sensitive, dyed purple with diamine rose G and sensitized for infra-red, and dyed grey, e.g. with diamine black BO and not specially sensitized for colour. As sensitizers for infra-red benzothiocarbocyanine ethyliodide, naphthothiotricarbocyanine ethyliodide and neocyanine are referred to, and for green thiopseudocyanine ethyliodide. In the case of material (1) printing is effected with green, red and infra-red light for the respective colour records and with white light for the supplementary layer. The latter may also be diffusely exposed to blue light. Other variants are described. The black layer in a kinematograph film may also be exposed with increasing amounts of light in each succeeding frame, forming a grey veil of varying opacity. Specification 397,159 is referred to.

[Class 28 (ii).] An attachment for the usual cross-bar d of a meat clamp comprises a springy strip a, c having marginal teeth f, the part a being deformed by the clamping pressure to accommodate itself to the shape of the substance. The parts c, which may be shaped to permit the attachment being mounted unsymmetrically on the bar d to avoid fouling the cutter, is attached to the bar by screws e and has downturned ends g which act as stops for the part a when deformed. An irregular arrangement of teeth f may be used, e.g., large closely arranged teeth at the sides and small teeth, more widely spaced, at the centre of the part a, this arrangement giving a strip of greater flexibility at the centre than at the ends. In a modification, the strip is inverted, i.e., the continuous part a is secured to the bar d and the parts c, which are then toothed, form cantilever gripping members. Alternatively, the parts c are secured as shown to the bar d, whilst the part a is divided centrally to produce two cantilever gripping members.

Title: Improvements in alloys and methods of preparing the same
IPC: C22C33/06
Filed: 1934-03-23
Abstract: Alloys containing iron, nickel, chromium, and copper are prepared by fusing in a furnace, preferably an electric furnace, a charge containing iron or steel scrap, high carbon ferrochrome and oxides of copper and nickel to form a metal bath and a supernatant slag and then adding to the bath a suitable reducing agent to reduce the metal oxides in the slag.  The nickel and copper oxides may be in the form of a calcined Sudbury ore and the scrap either low carbon steel scrap or iron-nickel-chromium-copper scrap of the same general analysis of the alloy to be made.  The charge may also include a material high in iron oxide such as roll scale or magnetic iron ore concentrate. Before the reducing agent is added, the metal bath is superheated until the carbon content of the bath is at or below the desired maximum percentage of that element.  The exothermic reducing agent such as ferro-silicon is added along with a basic agent such as burnt lime to reduce the chromium oxide present in the slag.  The alloys produced contain 10-30 per cent of chromium a combined nickel and copper content of 7-26 per cent with the proportion of nickel to copper about 2 to 1 and the balance substantially iron.  The alloys may contain less than 1 per cent of silicon, up to 3 per cent of other elements such as manganese cobalt, tungsten, and molybdenum either singly or in combination and up to 1 per cent of vanadium and titanium.  The carbon content is preferably 0,05-0,15 per cent.
