Title: Method and apparatus for checking gear teeth
IPC: G01B5/16
Filed: 1962-04-17
Abstract: 938,157. Checking gears. MICHIGAN TOOL CO. April 17, 1962 [May 1, 1961], No. 14845/62. Class 106 (2). Apparatus for checking a gear-wheel 16 for eccentricity and tooth spacing comprises a shaft 15 for rotatably supporting the gear 16, an index plate 22 co-operating with a plunger 23 to enable the gear to be successively rotated through an angle equivalent to the theoretical circular pitch. A pivotable feeler 28 is mounted on a carriage 27 which is urged by a compression spring 61 to slide in a groove 25 until the feeler 28 engages opposite flanks of a tooth 39 on gear 16. The position of the carriage is shown on a gauge 54. If there is variation in tooth spacing the feeler 28 has to pivot about pin 29 to enable notch 38 on an interchangeable tip of feeler 28 to engage tooth 39. This pivotal motion is transmitted through member 44 to a gauge 41. The results shown by gauges 41, 54 can be plotted on a chart (Fig. 5), having a plurality of circularly arranged graph segments. A second identical chart is placed over the first locating the origins of the graph segments on the second chart over a circle passing through the plotted points of the first chart. The difference between the centres 86, 87 of the charts is a measure of eccentricity. The feeler 28 may be rotated about an axis perpendicular to pivot-pin 29 and fixed to enable helical gears to be measured.

Abstract: 1,160,624. Hydraulic actuators. GENERAL ELECTRIC CO. April 3, 1967 [July 5, 1966], No.15055/67. Heading F1P. In an hydraulic actuator for operation in high temperature environments and comprising a piston 42 dividing a cylinder 36 into chambers 51, 52 selectively pressurized through conduits 22, 24 to cause extension or contraction of a piston rod 28, the cylinder chamber 51 being closed by a cap 38 supporting a shaft 73 rotatably driven by the piston 42 to thereby provide a piston position signal, the shaft is cooled and lubricated by pressure fluid passing from the chamber 51 through the space between the shaft 73 and a sleeve 80 into a housing 74 having an outlet 79. The shaft 73 is rotatably supported by a bearing 72 and is driven by a threaded member 71 screwed into a nut 70 fixed to the piston 42. When the piston rod is being extended the pressure in the chamber 51 is high, so that fluid flows therefrom into the housing 74 and thence to a tank through a conduit (not shown) connected to the outlet 79. A flexible cable (not shown) rotatable by the shaft passes through the conduit and thus transmits the piston position signal to a controller connected to the conduits 22, 24. During piston rod contraction the lower flow through the housing 74 due to the reduced pressure in the chamber 51 is supplemented by flow from the chamber 52 leaking past a piston rod seal 82 into a line 86 connected to the housing. A wheel 75 integral with the shaft 73 drives a worm, Fig. 3 (not shown) connectible by cables 77 to the worms of other actuators whereby all the actuators are operated in unison.

Title: Method of producing buckles
IPC: B22C9/06
Filed: 1945-06-15
Abstract: 593,852. Buckles. PLASCO, Ltd. (Crown Fastener Corporation). June 15, 1945, No. 15239. [Class 43] [Also in Groups V and XXII] A method of forming a buckle comprises diecasting a hasp having, at one end a ring-like socket and then die-casting a body member with a cylindrical bearing portion formed within and completely encircled by the socket, with freedom for turning movement in the socket. A two-part die with passages as shown in Fig. 1 is used. Molten metal is injected from a nozzle 12 into a gate 11 which feeds a cavity of the shape of the body portion 10 of the buckle and also another cavity shaped to form the hasp 9, the ring 15 of the hasp being formed around a core-bar 14.. The dies are then opened and the casting, with core-bar is moved down so that the .body portion 10 is below the die and the hasp 9 is held partially within a cavity 13 so that its ring 15 surrounds part of the cavity used for casting the body portion 10. The core-bar is withdrawn to its former position, the dies are completely closed and another casting is made, the straight portion of the body portion 10 being cast within the ring 15 of the previously cast hasp 9. The gate portions are later trimmed off to leave the completed buckles. Instead of metal a plastic may be injected into the dies. A bushing 16 may be placed over the core-bar to form an insert in the ring portion 15 of the hasp. If the buckle is of metal, the bush is preferably of a harder metal or of a fibrous material but may be of metal, fibre or another plastic if a plastic material is used for the buckle. The shrinkage of the body portion 10 on cooling will afford sufficient clearance for a' free movement of the hasp. Lateral movement of the hasp is prevented by integral cast heads 18.

Abstract: 1287646 Processing yarn MLG (COMBER) Ltd 19 April 1971 [1 April 1970] 15386/70 Headings D1B D1F and D1S Yarns, e.g. acrylic yarns, are processed by knitting the yarn loosely into a sock, subjecting the sock to a dyeing and/or bulking process, and then deknitting the sock. The word "loosely" is defined in terms of the number of intersections per unit area of the fabric after processing but before deknitting when the fabric is stretched in both dimensions to the limit of resilience, the number of intersections being not more than 10 times greater than the worsted count of the deknitted yarn. As shown in the Fig. a knitted sock is passed from bin 2 through dyeing rollers 4 (various methods of space dye application are described and then into steamer 10 via overfeeding apparatus 6 onto conveyer 8, the amount of overfeed being sufficient to allow shrinkage of the sock. After steaming the sock is passed in the same way through washer 12, optional scouring and finishing stages and dryer 14 and finally to bin 16. The sock may be deknitted by drawing the yarn from bin 16 through a guide for rewinding. Bulking may be improved by a second steaming step after drying and before deknitting. The process may be continuous. The dye may be applied to the sock by (a) dipping the rollers into dye baths and controlling the amount of dye reaching the sock by scraper blades, the rollers scraper blades and sock optionally being moved from side to side, (b) metering dye directly onto the rollers, the streams of dye being moveable from side to side, (c) metering dye directly onto the sock in streams or drops before passing the sock through the rollers, or (d) applying the dye from the flat topped spikes of a spiked roller, the spikes dipping into a dyebath or being provided with dye through bores in the spikes. The sock may be dyed overall to provide a background colour.

Title: Improvements in or relating to plasticised polyvinyl and polyvinylidene resin compositions
IPC: C08K5/10
Filed: 1946-05-24
Abstract: Plasticized compositions are prepared comprising a polyvinyl or polyvinylidene resin and a plasticizing amount, e.g. 1-60 per cent of a polyhydric alcohol di- or poly-ester of an o-aroylbenzoic acid (see Group IV (b) for the preparation and list of esters to be used). Polyvinyl and polyvinylidene resins include those derived from styrene, vinyl chloride, vinylidene chloride, vinyl acetate, acrylic resins, e.g. polymethylmethacrylate and copolymers in which vinyl or vinylidene compounds preponderate and vinyl-vinylidene copolymers. The plasticized composition may be admixed with a vehicle or dispersed in an aqueous continuous phase and auxiliary agents employed in coating compositions may be added.  In examples, triethylene glycol-di- (1) (o-(p-toluyl) benzoate) and (2) (o-(benzoyl) benzoate) are shown to be compatible with polyvinyl chloride, methacrylate and vinylidene chloride resins, in (3) a film-forming composition of the product of (1) and a polyvinyl chloride resin is prepared in toluene-methyl ethyl ketone solution and a solid vinyl chloride polymer plasticized by rolling with a mixture of the products of (1) and (2) and in (4) an aqueous vinyl chloride emulsion is prepared containing the product of (1).ALSO:Polyhydric alcohol esters of o-aroyl-benzoic acid are prepared by heating the acid and alcohol optionally in the presence of a catalyst and of a solvent for one of the reactants which is capable of entraining water.  The term "o-aroyl-benzoic acid" includes those benzoic acids having as an o substituent a benzoyl or alkyl substituted benzoyl group, e.g. p-toluyl, and may be substituted with groups inert to esterification such as alkyl, e.g. methyl, ethyl, propyl and alkoxy; e.g. methoxy, ethoxy and butoxy groups.  The term "polyhydric alcohol" includes alcohol-ether compounds and may be glycerol or polyalkylene or alkylene glycols, e.g. ethylene, propylene, butylene, di-, tri-, tetra-, penta-, hexa-, hepta-, octa-, nona-ethylene glycols or di-, tri- and tetra-propylene glycols.  Esters specified are the di-o-(p-toluyl) benzoates of mono-, di-, tri-, and nona-ethylene and dipropylene glycols, triethylene glycol-di-(o-benzoyl benzoate) and glyceryl tri-(o-(p-toluyl) - and tri - (o - benzoyl) - benzoate.  In examples: triethylene glycol-di- (1) (o-(p-toluyl)-benzoate) and (2) (o-benzoyl benzoate) are prepared from the corresponding acid and glycol by azeotropic distillation with toluene.  The esters are used as plasticisers (see Group IV (a)).
