Title: Improvements in or relating to the treatment of keratinic fibres to increase their resistance to felting
IPC: D06M13/364
Filed: 1964-09-18
Abstract: Keratinic fibres, e.g. wool, are treated with an alkali metal salt of N-dichloroisocyanuric acid by process in which the treatment is carried out in a first stage by means of an aqueous solution of the salt of N-dichloroisocyanuric acid of pH value 6-8 and in a second stage by means of an aqueous solution of the salt of N-dichloroisocyanuric acid having a pH value which is on the acid side of neutrality and is lower than the pH value of the solution used in the first stage, to improve their resistance to felting The treatment may be effected by acidifying the solution which has been used for the first stage treatment, e.g. with hydrochloric acid, and using it for the second stage treatment. The pH of the bath during the second stage preferably lies between 1 and 4.  The amount of active chlorine consumed in the first stage is preferably not less than half and not more than three quarters of the total amount of active chlorine required for the entire treatment.  The concentration of N-dichloroisocyanuric acid salt in the solution may be such that the active chlorine content of the solution is 2-6% by weight of the fibres treated and the ratio by weight of fibres being treated to the treating solution may be between 1:5 and 1:60.  The treatment may be carried out at 5 DEG  - 35 DEG C for a total time of 20-90 minutes. The treating solution may also contain an anionic, cationic or non-ionic surface - active agent, e.g. a condensate of ethylene oxide with lauryl alcohol, and the fibres may subsequently be dechlorinated with sodium bisulphite or hydrosulphite.  The fibres may be in the form of wadding, combed or carded ribbon, yarn, woven or knitted goods or made-up articles.

Title: Photographic apparatus
IPC: G03B15/04
Filed: 1970-08-14
Abstract: 1324415 Photographic apparatus EASTMAN KODAK CO 14 Aug 1970 [14 Aug 1969] 39290/70 Heading G2A Photographic flash apparatus comprises a holder 100 for receiving a percussion ignitable flash lamp unit and for locating a deformable or displaceable element thereof in a firing position, an actuating member 134 movable toward an element located in the firing position and means 121 responsive to the locating of such an element in the firing position for moving the actuating member 134 into non-firing engagement with the element. As described, the element is a striker 74 of a flash cube (20) Fig. 1 (not shown) having integral strikers, but it may be the primer of a single lamp or of a flash cube without integral strikers. The invention is described in connection with a camera (10). Sequence of Operation Positioning a flash cube on the camera depresses a T-bar 122 from its dotted line position to its solid line position, thereby rotating a lever 132 anti-clockwise (as seen) to release the actuating member 134. This rises under action of a spring 196 until an extension 166 engages and is stopped by the striker 74 associated with the forward facing lamp of the flash cube. At the same time a striking surface 194 is located at position b. Depression of shutter release member (14) frees a driver member (140) to open shutter blade 32, and also to strike the surface 194. The striking force is transmitted through lever 138 to the actuating member 134 to raise the extension 166, to the position c', and dislodge the striker 74 to ignite its associated bulb. This movement of the member 134 also causes a flag 182 to become visible in the camera viewfinder (18). As the flash cube is indexed, the extension 166 is cammed downwards by the flash cube base until the next striker is in the firing position. A rib (214) is provided on the camera to prevent tilting of the flash cube. The flag 182 may be arranged to signal an operative, rather than a used, flash bulb. Diaphragm Control Fig. 6 (not shown) In the case of flash exposure, the largest aperture is normally set by the daylight exposure system. However, for close up flash, a blocking lever (236) is allowed to engage a projection (234) on the diaphragm means (224) to position a smaller aperture behind the objective. The blocking lever (236) is automatically freed on depression of the T-bar 122, but is normally held out of the path of the projection (234) by a distance setting member (226).

A nestable container has a removable cover, the surface area of which is greater than that of the bottom of the container, the part or parts forming the cover being capable of being accommodated in the space left in the interior of the container when a similar container is nested therein. As shown in Fig. 5, the cover 4<SP>1</SP>, which may be of metal, rests on an inwardly directed corrugation 3 extending around the container 1. In Fig. 4 the cover is in three parts 4<SP>1</SP> hinged together, the central part having an upper eye 19 through which straps 17 and 18 are secured together to hold the lid in place. This lid can be folded up and placed in the bottom of the container. In Fig. 3 the lid comprises two parts 4, 5 connected by a central hinge, the hinge having means whereby the hinge pins 14 can be moved axially outwards through the side walls of the container to lock the hinge therewith, the other ends of the parts 4 and 5 having lugs 12 that engage in corresponding apertures in the end walls of the container. To the upper surface of the cover parts 4 and 5 wooden strips 7 may be secured and there may also be some small wooden blocks 9 arranged such that the base of a stacked container will fit between and be held by these blocks. When the lid is removed it is folded on itself and placed in the bottom of the container and a second container can then be nested therein. In a modified arrangement, Fig. 7, the corrugation 3 is absent but the containers have handles 25, 26, that can be swung inwards to act as supports for a stacked container. The cover, which is below said handles when swung inwards, may then comprise two sheets 29, 30, Fig. 8, of flexible material, the outer longitudinal edges of which are secured to the container walls as at 32 and the inner longitudinal edges of which are adapted to be connected to each other by a cord or wire passing through eyelets 33. The covers 29, 30, may be reinforced by strip like inserts 37. Alternatively a single sheet only is used, said sheet being secured to one wall and removably connected to the other walls, for example, by a slide fastener.

Title: Device for measuring fluid density
IPC: G01F1/12
Filed: 1973-08-14
Abstract: 1438715 Measuring density ROTRON Inc 14 Aug 1973 [14 Aug 1972] 39520/73 Heading G1S To measure the density of a fluid, a rotatable assembly is provided having a reactive screw member 29, 73 movable in a substantially straight path, drive means such as an electric motor 28, 69 acting to drive the screw member against a bias along the path when it is at a predetermined position but not when it is in a position in advance of the predetermined position, such that the screw member seeks a null position in which the bias forces exerted on the screw member balance the thrust of the screw member as it is rotatably driven in the fluid, means such as an inductance sensor 36, 98 coupled to a counter being provided to sense the rotary speed of the screw member 29, 73. In the apparatus shown in Fig. 1 the screw member 29 is mounted on an arm 13 which is pivotable about pin 26 against a mechanical or gravitational bias and which bears a magnet 38 operable as the arm 13 pivots to close and open a reed switch 39 to control the drive motor 28 in accordance with the position of the screw member 29. Alternatively, as shown in Fig. 4, the motor 69 may drive the screw member 73 via a clutch mechanism 75 such that the member driven, driven with slip or not driven according to whether clutch plates 87, 97 are fully engaged, partially engaged or not engaged, clutch plate 87 being driven by the motor 69 and clutch plate 97 being fixed to the screw member 73. When the apparatus is vertically mounted then the screw member 73 will attain a null position in which the net downward force of gravity, partly balanced by the upthrust of the fluid is balanced by the upward thrust of the screw member. Thus the speed of rotation of the screw member is a measure of the upthrust and hence the density of the fluid. To measure density with the apparatus mounted horizontally a magnet (116) is mounted on the screw member and repelled by a fixed magnet (119) mounted in front of the screw member, as in Fig. 7 (not shown).
