Title: Improvements in or relating to meters for measuring aggregate amount of fluid flowing therethrough
Inventor: BASS PATRICK
IPC: G01F15/06
Filed: 1967-10-09
Abstract: 1,246,611. Rotary fluid-flow meters. UNITED GAS INDUSTRIES Ltd. Oct. 8, 1968 [Oct.9, 1967], No.46010/67. Heading F1F. [Also in Division F2] In a gas meter a vaned rotor 2 is fixed to a rotary spindle 4 that is supported by a bearing member 10 and mutually-repelling magnets 5, 6 so that when the rate of flow exceeds a predetermined value the rotor can lift the spindle axially to engage a clutch 11 and thus initiate operation of an index coupled to a shaft 8. The predetermined flow-rate is the minimum rate for accurate operation of the index and can be adjusted by shifting the member 10 axially with the aid of screws 9. When raised the spindle abuts a spring-loaded thrust-bearing 7. In a second embodiment, Figs.3 and 4 (not shown), the clutch is replaced by permanently meshing gears and at low flow-rates the rotor is braked by a fixed sleeve (20) engaging with a peripheral ring (22) for the vanes. In a third embodiment, Figs. 5 and 6 (not shown), a control portion of the rotor (25) prevents full flow of gas until the flow through a by-pass passage (28) reaches the predetermined value. As shown in Fig. 8, a drive-shaft 44 for the index may be connected to the index 42 when the flow-rate is sufficient by a clutch 56, 58 controlled by a Pickering-type governor 54, 60, 62, 64, 66 through a toggle mechanism 68 to 82. Alternatively, the drive-shaft 101 is coupled (at the predetermined flow-rate) to the index by gears 120, 121 and an electro-magnetic clutch 123 controlled by a switch 124. A cam-plate 117 for the switch has pawls 118, 119 to engage with ratchet wheels 114, 115 fixed to a shaft 111, whereon the plate is mounted freely. The shaft 11 is coupled to a constant-speed electric-motor 113 and also by way of differential gears 103, 104, 105 to the shaft 101. Thus, when the speed of the shaft exceeds a predetermined value the shaft 111 turns to effect closure of the switch and when said speed becomes less than said value the shaft 111 turns in the opposite direction of open the switch. Alternatively, the plate 117 is coupled to the shaft 111 by gears instead of the pawls and ratchet wheels. In any embodiment a second index may be brought into operation at a flow-rate causing the first index to cease operating.

Title: Control line regulator

Abstract: 1,046,110. Wire compensator. PACIFIC SCIENTIFIC CO. Nov. 17, 1964 [Jan. 20, 1964], No. 46818/64. Heading F2G. '[Also in Division E2] A control line regulator comprises a regulator body 3, a driven member 17 connected to said regulator body to be driven by the latter, a pair of oppositely disposed sheave sectors 11, 11<SP>1</SP> adapted to receive control cables 14, 14<SP>1</SP> rig load regulator spring means 23, 23<SP>1</SP> carried by said regulator body and connected by forcetransmitting means to said sheave sectors in such a manner as to urge the latter to turn in opposite directions to maintain the cable under rig tension, wherein said force-transmitting means include locking means to effect the locking of said sheave sectors against relative turning movement when a control load is applied to one of the cables connected to one of said sheave sectors, said locking means comprising a crosshead 7 movably mounted on a flattened portion of said regulator body and having flat bearing surfaces engageable therewith to effect a predetermined positive controlled locking of said regulator. As shown, the regulator body is splined to a shaft 1 to which a driving arm 17 is also splined and the sheave sectors are rotatably mounted on the shaft by means of bearings. An I-beam extension 4 of the regulator body carries a cross-beam 7 connected to each sheave by pivotal links 8, 10, 8<SP>1</SP>, 10<SP>1</SP> which is spring loaded causing force to be transmitted by the links to maintain the control cables tensioned. When a control load is applied to one of the cables, one of the sheave sectors is rotated and the linkage causes the cross-head to tilt until a brake 5 (Fig. 3, not shown) engages the beam 4 and causes the regulator body to rotate, hence rotating the driving arm 17. In the event of a cable breaking a looking device comes into operation. A tube 21, 21<SP>1</SP> (Fig. 4, not shown) carries a fixed piston 39, 39<SP>1</SP> and a movable piston 33, 33<SP>1</SP>, a ratchet shaft 40 being attached to the fixed piston and received in a recess 41, 41<SP>1</SP> in the movable piston. The movable piston is connected to the cross head to move therewith. A spring-loaded looking pawl 44 is attached to the movable piston and in the case of a break in a cable is caused. to rock on pivot 45, due to its inertia, as piston 33 33<SP>1</SP> is accelerated to the right in Fig. 4 under the action of spring 23 acting through the crosshead 7. The pawl thus engages ratchet shaft 40 and prevents further movement of the crosshead.

Abstract: 1287609 Toothed gearing SMIT NIJMEGEN ELECTROTECHNISCHE FABRIEKEN NV 1 Oct 1969 [2 Oct 1968] 48320/69 Heading F2Q [Also in Division H1] A driving mechanism for the stepwise rotation of the moving contacts of a rotary switch-such as a transformer tap changing switch-is provided with a plurality of "maltese cross" elements so that successive stepwise movements of the moving contacts may have different angular magnitudes, the driving means including co-operating toothed wheels of elliptical form. The moving contacts of a rotary switch are carried by a shaft 19 to which are fixedly secured certain sectors of two "maltese crosses" 18, 21. Movement of these sectors to rotate the shaft 19 is effected by pins 17a, 20a respectively, which pins are carried by members 17, 20 rotatable by means of pairs of toothed wheels 6, 7 and 12, 13 respectively from a driving shaft 1.

The mean transmission ratios of the two sets of toothed wheels are equal and the design of the apparatus is such that the angular movement of the shaft 19 produced by the sector 21 is greater than that produced by each movement of the sector 18 but the angular velocity of the shaft produced by either sector is equal. If desired the toothed wheels 12, 13 may also be of elliptical form and each of the "maltese crosses" 18, 21 may consist of two or more sectors which alternate with one another.

Abstract: 1482675 Dense fibrous webs; finishing fabrics J W SUOMINEN OY 13 Nov 1974 [13 Nov 1973] 49179/74 Headings D1R and D1S A needle punched non-woven web consisting partially or exclusively of thermoplastic fibrous material is subjected to repeated blows, the heat thus generated being sufficient on its own or in combination with heat applied before or during the blows to raise the temperature of the fibres to the point at which they deform but below that at which they melt or adhere, so that the fibres deform so as to contact each other over larger areas of each fibre. The density of the web is thus increased, eg. 2.5 fold, to give a voids content of e.g. less than 20% and the frictional contact between fibres is so strong that the strength of the web is increased e.g. 4 or 5 fold. The ends of fibres at the web surfaces expand to produce a smooth-surfaced web.  The thermoplastic fibres exemplified are 50 mm, 1.5 denier polyester shrinkable fibres. Others mentioned are polypropylene, polyvinyl alcohol, polyamide, polyacrylonitrile and glass. An equal proportion of natural fibres may be present. The blows may be applied by a plate mounted on a shaft running transverse to the direction of travel of the web the preferably upstream end of the plate being connected by a rod to a crankshaft or wheel to rock the plate with a stroke length of 5 to 10 mm. Below the plate is an optionally heated and/or vibratingly sprung support. The web may be passed several times through the reciprocating apparatus. The frequency of reciprocation may be 200 to 1500 times per minute. Specified products are leather substitutes and a carpet.
