Title: Improvements in the manufacture and production of cellulose compounds
IPC: C08B3/00
Filed: 1932-09-09
Abstract: Cellulose is treated with strong phosphoric acid (at least 80 per cent strength) in the presence of a neutral organic liquid miscible with the phosphoric acid employed, and the cellulose phosphate separated and treated with an organic acid until the phosphoric acid radicle is replaced by organic acid radicle.  Part of the strong phosphoric acid may be replaced by sulphuric acid. Suitable neutral organic liquids are methyl acetate, ethyl acetate, and amyl acetate, and these may be used with another organic liquid, such as benzene, provided the mixture gives a homogeneous solution with the phosphoric acid.  Organic acids specified are acetic acid and oleic acid. According to a further feature, cellulose containing a small proportion of organic acid radicle may be treated in order to increase the content of organic radicle.  In an example, sulphite pulp is treated with a mixture of 95 per cent phosphoric acid and amyl acetate.  The fibrous material is then separated and placed in glacial acetic acid.  In another example, cotton linters after treatment with 88 per cent phosphoric acid and amyl acetate, are separated, and placed in glacial acetic acid.  A further example is given in which cotton linters are immersed in a mixture of phosphoric acid (sp. gr. 1,75), sulphuric acid (sp. gr. 1,84), and amyl acetate, filtered off, and treated with oleic acid.

Title: Apparatus and Method for Marine Seismic Exploration.
IPC: G01V1/38
Filed: 1967-06-01
Abstract: 1,153,390. Seismic surveying. TEXAS INSTRUMENTS Inc. 1 June, 1967 [7 June, 1966], No. 25238/67. Heading H4D. In a marine seismic exploration system utilizing relatively low energy repetitive seismic disturbances and seismometers for generating analogue electric signals of the reflected waves, digital electric signals representative of the analogue signals are produced in each seismometer channel and are utilized to generate further digital signals representative of an analogue signal waveform from more than one seismometer channel. The digital signals from each channel may also be separately recorded. In an embodiment a set of hydrophones is continuously streamed under water and the set is divided into groups, the electrical outputs from the hydrophones of a group being paralleled. The seismic source may be a gas gun operated at a frequency related to the speed of streaming. The outputs of the hydrophone groups are sampled by a multiplexer 23 which prefaces an analogue-digital converter 25 with a parallel output form; the bits of a digital word are sent simultaneously to a corresponding number of switches, e.g. 29, and switches, e.g. 33 are operated in synchronism therewith. Signals are magnetically recorded in multitrack form, Fig. 3. The played-back outputs on line 48 are fed to a digital-analogue converter 41 and thence after de-multiplexing (which includes conventional filtering for waveform smoothing) to a multi-channel longpersistence oscilloscope 46. A camera 47 may be added. Signal-to-noise is improved by summing several digital input words, Fig. 4 (not shown), the set of hydrophones being assumed to not have moved significantly in the interval. Multi-channel processing may follow (none shown); noise due to multiple reflexions is also reduced by common depth point stacking, Figs. 6 to 9 (none shown).

Title: New or improved liquid dispensing device
IPC: B01F15/04
Filed: 1958-08-07
Abstract: 868,690. Mixing liquids in flow. TACCHI, P. G. Aug. 4, 1959 [Aug. 7, 1958], No. 25298/58. Class 86 [Also in Group XXVIII] In a device for dispensing a pre-determined amount of secondary liquid into the flow of a primary liquid which is being discharged under pressure, the primary liquid passes through a pressure chamber 23 defined on one side by a flexible diaphragm 14 operatively connected to a piston 16 working in a cylinder 15. The other side of the diaphragm is open to atmospheric pressure through the passage 50. When the discharge nozzle of the primary liquid is closed, the pressure in the chamber 23 rises deflecting the diaphragm 14 and causing the piston 16 to draw in a quantity of secondary liquid from the supply line 26 past the non-return valve 27. If the discharge nozzle of the primary liquid is then re-opened, the pressure in chamber 23 falls again and the diaphragm 14 and piston 16 are returned under the influence of the spring 20, forcing out the secondary liquid through conduit 28, non-return valve 36, conduit 35, visual drip feed 31, conduit 34 and valve 43 into the chamber 23 where it mixes with the flow of primary liquid. The rate at which the secondary liquid is discharged is determined by adjustment of the needle valve 40. The device is primarily intended for use with a machine for discharging a jet of washing water, whereby the initial discharge contains a proportion of detergent and is followed by detergent-free water for rinsing; further supplies of detergent being obtainable by momentarily closing and re-opening the discharge nozzle.

Filed: 1971-04-19
Abstract: 1314914 Spring power storing mechanism MEIDENSHA KK 19 April 1971 [27 March 1970] 25449/71 Heading F2S [Also in Division H1] A spring charging mechanism for a circuitbreaker has a shaft 1 which is longitudinally movable in bearings 2a, 2b to stress a compression spring 3 between the bearing 4 and a shaft end-plate 4. A threaded portion 5 of the shaft 4 is screwed into a member 6 having teeth 7 interengaged with a gear-wheel 8 coupled through reduction gearing 9 to a reversable motor 10. Fig. 1 shows the spring in the stressed condition in which the shaft is held by a lever 12 engaging a thrust bearing 11 on the member 6 whilst the lever 12 is held by a latch 14. When an electromagnet 16 is de-energized its plunger 17 is driven against the latch 14 which releases the lever 12 to allow the spring 3 to move the shaft to the right to open or close the circuitbreaker. The teeth 7 of the member 7 are of such length as to maintain coupling with the gear-wheel 8 as the member 6 moves with the shaft 1. The motor 10 can now be driven in a direction to move the member 6 to the left until the lever 12 urged by a bias spring 13 is relatched. The motor 10 is then reversed and since the member 6 cannot move to the right due to the latched lever 12, the shaft is moved to the left to recharge the spring 3 ready for the next release operation. Tension springs (Fig. 4, not shown) may replace the compression springs 3 and the member 6 may have a single tooth engaged in a slot in an internally threaded gearwheel (Fig. 5, not shown).

Seals and scaling. - Apparatus for producing a wax or similar seal having a base and a central protrusion comprises a matrix for forming the peripheral part of the seal and a matrix for forming the centre of the seal, the first matrix being attached to a tube in which slides a member carrying the matrix for the centre of the seal. A cylinder 1, Figs. 1<a> and 2, carries at its base ring-shaped cutting and stamping matrices 8, 10. A spring- pressed plunger 2, 4 sliding in the cylinder and provided with a knob 6' carries at its lower end a seal 9 and can be projected into the hole in the ring 10 to serve as a punch in conjunction with the matrix 8. A strip of paper 11<1>, wound on spools 12, 13, passes under the central matrix 9,. and when the plunger 2 is pushed down a central part of the paper strip is cut out and is inlaid on the top of the wax. A piece of coloured string 18, Fig. 2, drawn from a spool 19 is passed into a groove 16 in the matrix 10, is secured by a spring 20, and becomes embedded in the wax. In operation, when the apparatus is pressed upon hot wax, the outer matrix 10 forms the ring part of the seal and secures the string in this part by the wax flowing into two depressions 17, Fig. 2<a>. The surplus wax flows along grooves 15 to the central portion and rises above the level of the outer ring, submerging the middle part of the string. On pressing the knob 6<1>, the plunger descends, cutting out a part of the paper strip 11' which is inlaid by the matrix 9 into the wax in the centre. The punch 4 may be of smaller diameter than the central opening so that the wax will flow up and form a ring between the impressions of the outer and inner matrices. Vertical grooves may be formed in the inner surface of the central opening to assist the flow of wax. The matrix 9 has projections corresponding to perforations in the paper strip 111. The paper 11<1> passes through slots in the body of the cylinder. Specification 220,920 is referred to.

Title: Process for manufacturing spheroidal graphite cast iron pipes by centrifugal casting
IPC: B22D13/10
Filed: 1975-06-16
Abstract: 1494139 Centrifugal castings PONT-A-MOUSSON SA 16 June 1975 [18 July 1974] 25552/75 Heading B3F  In the centrifugal casting of spheroidal graphite cast iron pipe, the rate of cooling of the exterior of the pipe is reduced at the same time as the rate of cooling of the interior of the pipe is increased to ensure a reduction of pearlite in the material crystal structure so that the pipe is more resilient and less prone to shock fractures. To reduce the rate of cooling of the pipe exterior, the rotatable mould 1 is coated with a wet spray from nozzles 3, 4 of silica and bentonite, which is subsequently covered, just prior to pouring, with a thin coating of powdered inoculating product from a nozzle 5, e.g. calcium silicate having a particle size less than 0À3 mm. To increase the rate of cooling on the pipe interior, during the pouring of liquid iron from a channel E, further inoculating particles are fed from a hopper 8 to fall into a front F of the liquid iron 18 to be dispersed therethrough. These particles progressively melt and in so doing extract heat from the liquid iron 18 so ensuring that from a zone 19 spaced from the mould surface to the free inner surface 20, the rate of cooling is increased. The particles from the hopper 8 are high melting point particles-e.g. of Fe-Si, Fe-Si-Ca-Zr alloys, alone or with steel or cast iron shot. The amount of particles supplied may be varied along the length of the front F and the particle size may also be so varied, e.g. the hopper 8 may have separate compartments. The hopper 8 has a rotatory distributer at its bottom driven remotely by a drive 16. Inoculating particles, e.g. of ferro-silicon, can be supplied to the liquid iron from a metered hopper 6, and carbon baffles 7 ensure mixing thereof. The mould 1 is supported in rollers C one at least of which is driven by a motor M. A core D is provided at the socket end of the mould. Either the mould, or the ladle H and pouring channel E, may be movable to cause relative axial movement during pouring of the mould.
