Title: Electrical filters
IPC: H03H17/02
Filed: 1976-06-28
Abstract: 1534199 Active filters FORD AEROSPACE & COMMUNICATIONS CORP 28 June 1976 [27 June 1975] 26888/76 Heading H3U A digital filter comprises a bidirectional shift register 44 connected in cascade with a further shift register 54, both arranged to be recirculating, and means 58 for combining outputs from the first stage of the bidirectional register and the last stage of the further register. Both registers have the same number of stages. When all the stages are loaded with m successive digitally encoded samples of an input signal on 42, a control signal CTL sets register 44 into the state in which data is shifted from right to left under the control of clock pulses CP, the recirculating loop 48 transferring the value in stage X 0  to stage X m-1/2 . Signal CTL also actuates gate 50 to complete the re-circulating loop 56 and to isolate the input line 52 from line 46, so that data in register 54 is shifted from left to right under control of clock pulse, the loop 56 transferring the value in stage X m  to stage X m+1/2 . At each step in the transfer, the values currently stored in stages X o  and X m  are combined in Adder/Subtractor 58 and the resulting value is multiplied by a weighting coefficient from PROM 68 which is addressed under control of clock pulse CP. This process is repeated for each corresponding pairs of values currently held on the registers and the results summed in adder 74 to give an output value Y. When the values held in registers 44, 54 have returned to their original positions, signal CTL sets register 44 to shift data from left to right, disconnects loop 56 and connects line 46 to line 52. The next clock pulse then steps both registers one stage, writing a new input value into X o , writing the value previously in X m-1/2  into X m+1/2  and discard ing the value previously in X m . The recirculating process is then repeated to derive a new output value of Y.

Title: Method of and apparatus for continuously casting metal
IPC: B22D11/14
Filed: 1956-09-03
Abstract: 804,718. Continuous - casting - machines. BABCOCK & WILCOX CO. Sept. 3, 1956 [Sept. 22, 1955], No. 26898/56. Class 83 (1). In a continuous-casting process, the molten metal is poured from a source at a substantially uniform rate co-ordinated with a substantially uniform casting-withdrawal rate, but the molten-metal delivery-rate to the upper end of the mould is cyclically changed so that the level of molten metal in the mould varies in a selected pattern. The apparatus comprises a tilting-furnace 10 which discharges into a tundish 12, which in turn delivers into a second tundish 15 arranged for intermittent discharge into the mould 16. The mould and tundish 15 are constructed, and adjustably-mounted, as disclosed in Specification 800,321, one end of the tundish being raised and lowered by a cam-shaft 61 rotated in alternately-reversing directions by a motor controlled by a contact-arm 65 clamped to the shaft 62. An after-cooling-zone 20 is enclosed by a housing 82, coolant from the sump 87 being withdrawn through filters 92, and returned through a pipe 93 to spraynozzles 95. A control-mechanism 100 receives indication of the molten metal levels in the mould, compares them with a desired set of conditions, and regulates the tilting-rate of the furnace accordingly. A manual-control in the mechanism 100, electrically-connected to the withdrawal-rolls 17, enables the withdrawalrate to be regulated in accordance with the requirements of the particular metal being cast. In a modification, Fig. 5, a tundish 105, delivering to two moulds, is mounted on a centrallydisposed shaft 114 and rocked by a driveneccentric. In a further modification, the tundish has a discharge-nozzle which is controlled by a stopper attached to a lever which is oscillated by an eccentric.

According to the invention the lower end of the pillar is bent laterally below the sleeve so that, when the relative angular movement between the pillar and sleeve takes place, the end of the pillar bears against the side of the socket and simultaneously causes a gripping action between the socket and one side of the sleeve 4. In the constrsction shown in Fig. 1 the upper end of the sleeve 4 is attached to the frame 3 of the screen 2 and the pillar 9 is extended to form a handle 10 for rotating tha pillar; while in a modification, the pillar 9 is attached to the frame 3 and the sleeve 4 is formed with a handle for rotating the sleeve.

Capacitor 14 discharges during the retrace period and is recharged via inductor 16 during the sweep. The resulting voltage across capacitor 14 is coupled to the gate of thyristor 1 to prevent triggering during the sweep period. Alternatively, a capacitor may be connected between capacitor 14 and the gate for this purpose. The winding 7 may alternatively be connected in the cathode circuit of thyristor 1 or in the earthy side of winding 3. An R.C. circuit may be connected in series with resistor 12 so as to facilitate starting. The value of capacitor 9 should be 2-5 times that of capacitor 10. The input circuit of thyristor 1 may be protected by a Zener or conventional diode.

Abstract: 536,811. Hydraulic power transmission. JONES, W. L. (Automatic Turbine Co., Inc.). Oct. 3, 1939, No. 27123. [Class 69 (ii)] A hydraulic coupling is constructed with one or more rotary impelling vane members 2, 9 secured by screws to a flywheel 1 and a casing 3 filled with liquid which can be renewed from a reservoir 27 with which it is in constant communication via apertures in the driven shaft 8 the liquid being kept under pressure by a spring piston 28, or by pneumatic pressure acting on the liquid in the reservoir. The casing 2 is also fitted with driven rotary turbine members 7, 17 splined to the driven shaft and formed with apertures 23, 25 to permit of the flow of liquid The member 7 is capable of a limited free sliding movement on the shaft 8 and moves away from the impeller 2 upon slow movement of the driving motor, to a limited extent, but returns towards the impeller 2 on increase of speed so as to do away with slippage and prevent friction which occurs when slow running takes place. The vanes on the driving and driven members may differ in number and as shown in Figs. 2, 3, 5, are constructed so as to form buckets 46 by forming one side 45 with a straight edge and the other side concave, the vanes on the driving rotor having the concave sides forward and on the driven rotor the concave sides rearward. The concave sides are provided with lateral flanges, and as shown in Fig. 2 these lateral flanges diverge outwardly and inwardly from an annular ring 49, and the inner flanges 50 are formed with bevelled -upper surfaces. As shown in Fig. 25 the ring 49 is omitted and the motor has vanes 221 forming tapering brackets 222 which decrease towards the hub 223.

Patent GB-710257-A (GB)
Title: Wood pulp
IPC: D21C3/06
Filed: 1950-11-07
Abstract: Cellulose pulp is obtained by impregnating wood with an acid sulphite digesting liquor at a temperature not exceeding 120 DEG C. and then heating the impregnated wood to a temperature between 190 DEG C. and 205 DEG C. and maintaining the temperature within this range until the digestion is substantially complete.  Cellulose pulp of high quality suitable for acetylation, with little or no further purification, is obtained.  Following the impregnation, part or all of the excess sulphite liquor may be drained from the wood chips. The sulphite liquor may be a solution of sodium or calcium bisulphite.  During the digestion at 190-205 DEG C. the pressure may be maintained at 225-260 p.s.i.g. by relieving the pressure in the digestion vessel continuously or intermittently. After the digestion, the pulp may be given a simple bleaching and a light purification with dilute alkali solution.  The impregnation and subsequent digestion of the wood may be carried out as a single continuous operation.  The process may be carried out in apparatus such as is described in Specification 710,330. In an example, hemlock chips are immersed for two hours in an excess of a calcium sulphite cooking liquor containing 5.5 per cent. of free SO2 and 2.33 per cent. of combined SO2, at a temperature of 110 DEG C. and a pressure of 70 p.s.i.g.  The chips are drained and then heated with steam for seven minutes to raise the temperature to 195 DEG C., the pressure being maintained at a maximum of 225 p.s.i.g.  The cellulosic material is kept at 195 DEG C. for one minute and then cooled rapidly.  The pulp obtained is bleached with dilute sodium chlorite solution and washed. It may then be acetylated and the cellulose acetate may be dissolved, e.g. in acetone, and formed into filaments or films.
