Title: Improvements in or relating to flexible tubing
IPC: B29D23/18
Filed: 1959-12-22
Abstract: 933,172. Flexible tubes. R. E. DARLING. Dec. 22, 1959 [Dec. 29, 1958], No. 43549/59. Class 99(2). A flexible tube comprises an impervious carcass 10, 14, Fig. 2, non-metallic material having helically-formed corrugations reinforced by means, such as a helical spring 12, which extend along the length of the carcass, and one or more restraining cords 22, Fig. 3, within the tube for limiting axial separation of the ends of the carcass. In making the tube, a partially-expanded, metallic, helical spring 12 is applied about a partially-cured, elastomeric tube 10 stretched over a mandrel and is secured to the tube 10 by adhesive tape or cement. A sheath 14 of fabric or elastomeric material is placed over the tube 10 and spring 12 and the assembly is transferred to a mandrel of smaller diameter. Corrugations are formed by winding nylon cord or wire between the spring convolutions and the assembly is partially cured. Electrical conductors 20 and non-elastic restraining cords 22 encased in a sheath 24 are sucked through the bore of the tube, the cords 22 being secured to the ends of the spring 12 and the sheath 24 projecting radially through the wall of the tube. End fittings 16, 18 are moulded to the ends of the tube and the assembly is finally cured. Alternatively, the conductors 20 and the cords 22 are positioned in a taut condition within the bore of the flexible tube.

Abstract: 1,200,125. Dyeing. SAMUEL PEGG & SON Ltd. 17 Sept., 1968 i[26 Sept., 1967], No. 43702/67. Heading D1L. In the steam treatment of a batch of stockings 10 before, after or at the same time as recycle spray dyeing in a chamber 2, the steam is fed through a perforated pipe 4 and the dye liquor is recycled to a spray head 7 by a pump 8. On completion of the dye-recycling phase, the recycled liquor is returned, under the action of the steam, from the spraying circuit via pump 8 and a valve 29 to a feed tank 12, whereafter a quantity of liquor flows from tank 12 via a valve 26 to an evaporator tank 14 (to remove condensed water), water and a predetermined quantity of make-up liquor or then added via valves 27 and 28 to tank 12, and (after any further treatment of the stockings) the contents of tanks 12 and 14 are then returned to the spraying circuit for treatment of a fresh batch. Completion of passage of recycled liquor through pump 8 is sensed by a probe 31 which operates closure of valve 29 and opening of valve 26. After the required quantity of liquor has flowed to tank 14, a probe 24 operates closure of valve 26 and opening of valves 27 and 28. Tank 12 then fills until a probe 25 effects closure of valves 27 and 28.

Filed: 1971-09-27
Abstract: 1330719 Acoustic flowmeters NUSONICS Inc 27 Sept 1971 [24 March 1971] 44971/71 Heading H4D An acoustic flowmeter comprising, upstream and downstream transducers mounted on opposite sides of a pipe, each transducer being alternately in the transmit and receive modes; a pair of oscillators for energizing the transducers individually at different times; first means having an input connected to the receive mode transducer and an output connected to the transmit mode transducer for maintaining the received pulse amplitude constant; second means connected to the receive mode transducer and the oscillator driving the transmit mode transducer for maintaining the frequency of the oscillator proportional to the transit time of the pulses from the transmit to the receive mode transducer and means for obtaining the frequency difference between the two oscillators. In a device for measuring flow velocity or mass flow rate, counter 28 produces at one time a signal AE which opens switches 34A, 40A, 52A and 26A and closes switches 34B, 40B, 52B and 26B. The counter 28 produces a pulse at output 1 which drives upstream transducer 20A through amplifier 30A. Downstream transducer 20B passes the received pulse through RF amplifier 37, peak detector diode and capacitor 38, 42A to a differential amplifier 44A. The amplitude of the pulse is compared to reference 46 and used to control amplifier 30A thereby maintaining the received pulse amplitude at a given level. The R.F. amplifier 36 output also passes through threshold detector 48 to comparator 50. The second input to the comparator is from counter 28 which produces an output after N input pulses have elapsed from the transmit pulse. The time difference between the two inputs to the comparator 50 produces a voltage which is compared with reference 58 and used to control the frequency of oscillator 24A to have a period 1/N times the pulse transit time. Counter 28 now reverses the switches to produce a similar result for a pulse transmitted from transducer 20B to 20A. The frequency difference is detected and used to drive display 62.
