Filed: 1975-03-12
Abstract: 1502161 Measuring displacement photoelectrically PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 12 March 1975 [15 March 1974] 10281/75 Heading G1A A displacement transducer for a machine tool component comprises a grating 4 connected to the component and disposed in the light path between a light source 1 and a row of line-shaped substantially identical photo-sensitive elements 6, elements spaced apart by the grating pitch being electrically inter-connected to form a multiplicity of assemblies which are sequentially activated in groups by ring counter 7 to simulate a grating travelling over the surface of the elements 6 at constant speed, the output 13 of the elements being compared with a reference signal 14 in a buffer counter 11. In the embodiment one hundred and eighty photo-diodes cover thirty pitches of the projection of the grating 4, giving 6 diodes per pitch. Alternatively 5 or 10 diodes per pitch may be used. Corresponding photo-diodes of each set of 6 consecutive ones are inter-connected to give six groups which are activated three at a time to simulate a grating with a black/white ratio of 1:1, and a pitch equal to that of the projection of grating 4. The electronic processing circuit also comprises a clockpulse generator 10, and dividers 8, 9 and 20 the latter providing a reset signal of a frequency equal to the frequency of measuring signal 13 when the grating 4 is stationary. The phase difference between the sensed output signal 13 and the reset signal gives the position of the grating within the range of one pitch thereof.

Title: Improvements in and relating to channel-formed repeaters for rolling mills
IPC: B21B41/06
Filed: 1934-04-06
Abstract: 426,374. Rolling. ERICSSON, N. O. J., Bofors, Sweden. April 6, 1934, No. 10484. [Class 83 (iv)] A guide 4 for returning work back to a rolling mill, Fig. 5, has a gradually decreasing radius of curvature towards its exit end. The guide is formed of two telescoping parts 4 and 32 and its shape is such that a flat bar pushed into it is rotated through 90‹ and emerges edgewise, i.e. with its major axis vertical. The work is directed by the guide tube 5, Fig. 6, into the guide 4 and travelling round enters the guide jaws 74, 75, Fig. 11, on its way to the rolls. This raises the jaw 75, operates lever 81 to lower the valve 86, closing atmospheric port 90 to connect conduit 23 with the compressed air supply 93, so that the pressure in the conduit 23, Fig. 6, depresses the piston 11 and pivots the tube 5 down outside the guide 4, so that a free loop can be formed in the work and upsetting is eliminated. To delay this action until the rolls have actually gripped the work, a throttle valve 21, Fig. 6, is adjusted to give a delay action. This operation may also be carried out electrically or by photoelectric cell. When the latter end of the work has passed through the jaw 74, 75, the jaw 75 drops, cutting off the air supply to the piston 11 so that the spring 16 draws the tube 5 back within the guide 4. When the work is to be received and returned to other roll grooves and the guide 4 therefore moved bodily, the block 42, Fig. 9, to which it is suspended, is moved bodily along a fine adjustment screw by a handle 46, while for longer displacements the whole suspending mounting is displaced along the screw 52 by the handle 54. Fig. 7 shows a cross-section of a return guide near its receiving end in which the free space 29 can be adjusted by sliding the inner side 26 nearer the side 25 and securing it there. The parts 26a, Fig. 8, of the side 26 can be slid over each other, and adjusted when the halves of the repeater are telescoped into one another to suit the roll passes selected. In feeding the work back to the rolls it passes through a guide tube 69, which on lifting of a bridge piece 72 can be swung aside so that the guide jaws 74, 75 can be replaced. Specification 418,619 is referred to.

Filed: 1962-03-20
Abstract: 1,004,883. Producing taps; screws. RESEARCH ENGINEERING & MANUFACTURING Inc. March 20, 1962, No. 10743/62. Headings B3A and B3N. A thread-forming screw or tap, having a generally cylindrical main shank portion, is rolled between dies to produce a helical thread which has formed on it, or spaced from it on an extension of the helical thread path, a number of projections for causing swaging of an internal thread in a parent body. The projections lie on a spiral which tapers towards the work entering end. Projections 31, Fig. 5, form threads in a parent body fractionally larger than the threads 30 in order to reduce driving friction. The threads at the entering end may be dispensed with, Fig. 9, the projections still following the helical thread path. To facilitate forming of the projections, depressions may be produced laterally or longitudinally on one or both sides of each projection. Longitudinally assymetrical projections, Fig. 5, or projections formed with displaced depressions 109 and 110, Fig. 28, to form a wave, may be provided. In the case where a screw is to be held tightly without using a lock washer the threads themselves can perform a small amount of swaging.

Title: Improvements in or relating to electric liquid heaters
IPC: F24H1/10
Filed: 1939-04-06
Abstract: 527,511. Electric liquid heaters ; electric switches. McDOWELL, O. A., and DONE, J. P. C. April 6, 1939, No. 10830. [Class 39 (iii)] [Also in Group XXXVII] In an electric liquid heater of the flow type provided with means, actuated by the pressure of the liquid, for completing the circuits of a plurality of heating elements in succession, the control member is impervious to liquid. Inlet and outlet headers 14, 16 are connected by three flattened tubes 18 of sheet metal of the same width as the headers. Heating elements 20, of resistance wire between mica sheets, are placed between the tubes, which are lagged at 24, and clamped by bars 28 to a panel 12. The inlet pipe 32 is restricted at 36 to build up fluid pressure which acts on a diaphragm 38 connected to an insulated switch bar 56 which is adapted to make contact in succession with two contacts 66. 68. These contacts are connected to relays 70, 72 which control the circuits of two groups of heaters 20, so that these are energized in succession when the water is turned on. Successive energizing of the heaters may be effected by a mercury switch, Fig. 5. An iron plunger 112 normally floats on mercury 108, but when drawn down by a magnetizing coil 110, mercury is displaced into the tube 106 and reaches the contacts 114 of the heater circuits in succession. In an alternative form of pressure actuated switch, Fig 6, a diaphragm 116 subject to the flowing water, moves a lever 126, 127 carrying a magnet 142 which actuates an armature 140 normally held out of contact with mercury 134 by an insulated float 136 but completing a circuit with the mercury when the magnet 142 is moved down. This switch may control the magnetizing coil 110, Fig. 5.

Title: Manufacture of pulp or fibrous material
IPC: D21C3/00
Filed: 1926-04-24
Abstract: 266,168. Marr, R. A., and Ramar Syndicate, Inc. April 24, 1926. Retting.-Strong pulp and fibrous material are obtained from various kinds of cellulosic and ligneous material such as soft and hard woods, cane (machrosperma arundaria and machrosperma tecta) bamboo, straw, grass, sedges, marsh grasses, banana stalks and leaves, bear grass, coconut husks, &c., in a green or dried condition by boiling under a pressure of 70-120 lbs. with relatively dilute solutions of salts which have the effect of rendering the cementitious matter readily friable without dissolving the lignin. Sulphates of sodium, potassium, magnesium, aluminium, copper, iron, and manganese or mixtures of two or more of them may be used with or without the addition of soluble salts such as sulphates, chlorides, or nitrates of chromium, cobalt or nickel, and, in some cases, zinc salts. Solutions of mixed salts such as kainite, sea salt, soluble nitrates of the alkalies and alkaline earth metals can also be used, either alone or mixed with any of the above. Solutions of strength less than 4 per cent are found to be most suitable, the strength varying according to the product required. Wood, cane, or bamboo, in the form of chips or small pieces, are cooked for 1-4 hours, then washed, crushed by rollers edge runners, or other suitable machines and then brush-beaten in a beating engine to pulp which can be sheeted and made into paper. Rubber latex may be added, with or without a waterproofing agent, to obtain a light, rigid, tough moulded article, which may be polished. Fibres for stiff brushes and pulp for making artificial lumber may be obtained from cane by treating with a solution containing the sulphates of magnesium, sodium, and potassium. In the preparation of fibres for spinning, for rope making, for gunny cloth and the like, a lubricant such as an emulsion of lubricating oil and soap or an amulsion of lanolin or degras with soda solution is added after cooking and washing. For coarse bristles for brushes, the cooked material, preferably after oiling, may be passed through slitters spaced to produce the thickness desired. The fibres may be dyed with cotton dyes and waterproofed as by of a mixture of lead acetate with agar agar, dextrin or gum, and either alum, aluminium sulphate, or a solution of copperas. In treating bamboo, the nodes may be cut out and pulp prepared therefrom while the lengths are used for obtaining fibres.
