Filed: 1964-11-20
Abstract: 1,019,370. Reinforced hose pipe. FLEXIBLE TUBING CORPORATION. Nov. 20, 1964 [Nov. 29, 1963], No. 47379/64. Heading F2P. A reinforced flexible hose, e.g. for vacuum cleaners, includes a helix of self-supporting material, and a flexible wall comprising one or more plastics strips covering the helix, the hose being characterized by a plurality of longitudinally reinforcing cords disposed directly over the inner strip either substantially parallel or skewed at an angle of up to about 30 degrees to the hose axis; and one or more helically disposed elements located over the longitudinally reinforcing cords between the turns of the helix and containing the inner strip and longitudinally reinforcing cords radially inwardly between the helix turns to impart a corrugated form to the wall structure. As shown a helix of steel wire 10 coated with a layer of vinyl plastics 11 is covered by a helically wound single strip of vinyl plastics 13 with its turns overlapping. Disposed over this, preferably perpendicular to the turns of the helix 10 are reinforcing cords 14 preferably up to 10 disposed around the circumference of the hose. Helically wound at each side of the helix 10 are two cords 15, 16 acting to cause the cords 14 and strip 13 to form corrugations around the helix 10. Around the hose thus formed are helically wound at least one strip (as shown, 17, 18) with overlapping turns. In the specific embodiment each strip 17, 18 covers three coils of the helix 10. The strips 13, 17, 18 and coating 11 may be fused together by means of a solvent or by heat.

Abstract: 1,201,142. Milking machines. H. W. BURRY and O. H. BURRY. 24 Jan., 1968 [24 Oct., 1966; 18 Oct., 1967], Nos. 47656/66 and 47501/67. Heading A1M. [Also in Divisions G1 and G3] Weighing apparatus in a milking machine comprises two containers 1, 3 connected in series to a milk supply line 6 and a valve 20 actuated in dependence on the weight of milk in the container 3 so that a vacuum is applied to the container 1 via the container 3 as long as the weight of milk in the latter has not reached a predetermined value, at which value the milk is automatically released on admission of atmospheric pressure to the container 3 and the vacuum is then applied directly to the container 1. The container 1 is fixed on a framework 2 whilst the container 3 is suspended from a helical tension spring 4 passing through a tube 4<SP>1</SP>. A rod 29 passing through a flexible diaphragm 30 is connected to links 26, 27 attached to the lower end of the spring. A valve 31 at the end of the rod closes the outlet 9 to the milk delivery line 10, 11 to which a butterfat sampling device 13 is connected. Initially milk flows into the container 3 from the container 1 via a line 14 and a non-return valve 15. Vacuum from a line 22 is applied through the valve 20 to the container 3 via a line 24 and to the container 1 via the line 14. On the container 3 reaching a predetermined weight, it moves downwardly causing a toggle 25 to actuate the valve 20 which supplies vacuum to the container 1 Via a line 23 and atmospheric pressure to the container 3. The non-return valve 15 closes and due to the equalization of pressure on both sides of the diaphragm 30 the spring 4 causes the valve 31 to open. The milk flows into the line 10 and the cycle is restarted when the container 3 is empty. A counter may be connected to the valve 20 or its associated linkage. The baffle 8<SP>1</SP> of a deflector 8 directs the milk towards the container wall to avoid frothing of the milk, and during cleaning of the container a spreader 8<SP>11</SP> is rotated to a position below the opening 7 to direct cleaning liquid over the container walls. The vacuum is applied to the milk claw through the line 6 and is also used to raise the milk to the line 11.

Filed: 1973-10-12
Abstract: 1444617 Function generators T MATSUMOTO 12 Oct 1973 47825/73 Heading G4G [Also in Division G3] A logarithmic recording system having different recording ranges each corresponding to a digit in the value being recorded, comprises a range-switching amplification circuit 28, 11 the output of which is compared to the output of a logarithmic potentiometer 18 in a differential amplifier 13, the latter providing power for a motor which drives the common shaft of the recording pen, the log. pot. 18 and the range switches 11, 20. Resistances R 1 -R 7  arranged in the feedback path of amplifier 28 have increasing values such that each is 10 times the preceding one. They are connected to the segments 22c to 22i of a rotary switch 22 having wipers 22a, 22b angularly spaced to provide a makebefore-break action. The output e A  of amplifier 28 is applied to terminal 13a of differential amplifier 13 and the output e B  of log. pot. 18 is applied to the other terminal 13b. The output of amplifier 13 is converted to A.C. and used to drive a servomotor (not shown) having a shaft 19 common to the log. pot. and to a rotary switch 20. Wipers 20b, 20c of switch 20 are so arranged that, as the wiper 18b of the log. pot.1 8 moves across the gap between the extremities 18c, 18d of the logarithmic winding 18a, one of the wipers 20b, 20c moves out of contact with the single electrode 20a. Thus at the upper or lower end or a particular range, the switch 20 is actuated to energize one of the relay windings Y 1 , Y 2  and to de-energize the other. During the short space of time that both wipers make contact with the electrode 20a the system is balanced by contacts Y 1A , Y 2A  and neither relay is operated. Relay contacts Y 1B , Y B2  are connected to the wipers 22a, 22b of range switch 11 and the range switch is driven from the servomotor shaft hrotgh a rueduction gear in such a manner that the wipers make contact with two adjacent segments as the relays are actuated. Thus, a smooth transition from one range to the next is achieved. For decreasing values of the input signal, the system operates according to a reversal of the above procedure. A modified log. pot. is described (Fig. 3, not shown) which consists of two series-connected semicircular windings each with a respective wiper, the wipers being so orientated that one wipes through 0 to 180 degrees before the other wipes through 180 to 360 degrees. The points corresponding to 0 and 360 degrees are connected to terminals T 11 , are connected by a conductor. The wipers are connected to the terminal T 10  through a twoway switch.

[Also in Division F2] An engine-driven speed-responsive pump 17 discharges to a vehicle steering gear 10 via a flow orifice 42 and a clearance 56 between a cup 49 and an outlet nipple 24; the flow through the primary orifice 42 depends upon the extent to which a spring-loaded valve obturator 37 opens a by-pass 47. The obturator has surfaces 36, 40 which are acted upon by the pressures at the nipple 24 and the pump discharge port 30, respectively, the surface 36 being open to the nipple 24 through an orifice 48. Rising flow speed resulting from increasing engine speed is countered by reducing the pressure on surface 36 and increasing the opening of the by-pass 47, viz advancing flow characteristic. The clearance 56 may be formed inside the nipple 24. In a modification Fig. 3 (not shown) the clearance is not provided and the by-pass is close to the primary orifice so that fluid flowing to the former moves close to the latter so reducing the effectiveness of the primary orifice to give a drooping flow characteristic. An additional dumping port may be provided opening into the valve bore between the obturator lands Fig. 4 (not shown) and which after a given obturator movement is connected to the by-pass. In a further modification Fig. 6 (not shown) the primary orifice has a contoured rod passing therethrough which is attached to the obturator. A ball-type safety-valve sits in the obturator to relieve excess pressure at the rear of the latter to the by-pass.
