Title: Apparatus for making webs of strand
Inventor: NESS DAVID WINFIELD VAN
IPC: D04H3/04
Filed: 1966-06-28
Abstract: 1,146,908. Laminates. STAUFFER CHEMICAL CO. 28 June, 1966, No. 28939/66. Heading B5N. [Also in Division D1] An apparatus for forming webs of strand by helically winding strands around an endless pair of parallel side members is characterized by the use of helical metal springs as the side members, see Fig. 3. The parallel reaches of the springs can be supported in tubular guides 44 and/or between two endless V-belts, (50, 54, see Fig. 2, not shown). Guides 44 or the V-belts can extend the whole length of the parallel reaches. As shown in Fig. 1 the strands, e.g. of vinyl resin, are wound from the spinner ring 26 around the parallel reaches of the endless springs 10. The tension in each spring 10 can be varied by the position of roller 12 on plate 24. Thus the pitch of the deposited strands can be varied. The spring and web are advanced through slotted guides 44 by a motor 20 which also drives the spinner ring. Thus the spacing and angle of the strands in the web can be varied. The web is then sprayed with plastics containing a curing agent and has a continuous sheet of plastics or paper applied thereto by device 72. The web then passes through drying or curing ovens 76 and is severed from the springs by knives 78 and is wound up by means 80. As an alternative to spraying the web with plastics the web can be passed through heated rollers (94) to heat-seal the strands together, see Fig. 4 (not shown). These rollers can be used to heat-seal strands of vinyl resin, fibre glass or nylon into a thermoplastic sheet.

Patent GB-1428375-A (GB)
Title: Piston and cylinder device
IPC: G01F11/04
Filed: 1972-06-21
Abstract: 1428375 Pipette filler JOHN POULTEN LTD 12 Feb 1973 [21 June 1972] 29152/72 Heading B1X [Also in Divisions F1 and F2] A device for filling and emptying a pipette 31 comprises a cylinder 1 and a piston 5 slidable therein, the inoperative position of the piston 5 being determined by the degree of threaded engagement between a non-rotatable piston rod 6 fixed to the piston and a further rod 12 provided with a knurled knob 13. In the inoperative position a spring 16 bearing against a fixed guide plate 9 urges a flange 14 on the rod 12 against a cover 2 secured to the cylinder I by a threaded collar 3. In use, after immersion of the pipette's tip in liquid, it is filled either by turning the knob 13 to move the piston away from the pipette 31 or by releasing the knob from a previously depressed position so that the spring 16 returns the piston to the position shown. Discharge of the liquid is then accomplished (a) by turning the knob 13 in the reverse direction, or (b) depressing the knob 13 against the action of the spring, or (c) by opening an orifice 20. The orifice 20 is opened by unscrewing a cap 32 or by operating a finger-controlled valve (35), Figs. 3 and 5 (not shown). Two arrangements for sealingly holding the pipette are described (see Div. F2).
Patent GB-857307-A (GB)
Title: Miniature photographic camera for perforated roll film
IPC: G03B19/04
Filed: 1958-09-12
Abstract: 857,307. Roll-film cameras. KAMERA-WERKE NIEDERSEDLITZ VEB. Sept. 12, 1958 [Nov. 9, 1957], No. 29206/58. Class 98(1) A roll-film camera has the following combination of features:- (a) the shutter mechanism is set and released by a single actuation of its operating member, (b) the film-advancing mechanism is actuated by a plunger projecting from the camera casing, (c) the shutter mechanism is locked against ooeration a second time until the locking means is released by actuation of the film-advancing mechanism, (d) the filmadvancing mechanism is locked against operation a second time until the locking means is released by actuation of the shutter mechanism. The film is transported by a claw-feed 34 which engages in a perforation of the film strip 14, and which is attached to an operating member 3. This is connected by a lip 33 to an operating bar 10 acting against a spring 12. By pushing bar 10 inwards, Fig. 1, the film is transported, and a locking member 4 latches into an aperture 36, so retaining the feed member 3. The shutter is operated by pressing button 7, which forces the operating member 2 downwards. A projection 21 on the latter engages the shutter-actuating lever 16, which first sets and then releases the shutter during the same single movement. Depression of member 2 also allows the doublearmed lever 5 to be swung clockwise into the position shown in dotted lines (Fig. 4). In this movement, one arm 53 engages under shoulder 43 to lift locking member 4 clear of feed member 3, so releasing the latter for'return to its original position under the action of spring 12. The clearing movement of member 4 is limited so that its shoulder 43 still engages against arm 53, thus preventing the shutter-actuating member 2 from being fully retracted into its initial position. This cannot occur until the operating bar 10 is once more pressed for a further film wind, when an extension 35 on the feed-operating member 3 strikes against a lever 6 which pushes lever 5 completely clear of the locking member 4, so allowing complete retraction of member 2. This arrangement precludes a double exposure. Figs. 10-18 (not shown) are of substantially the same mechanical construction, with a modified arrangement of the locking means.

Title: Positive shut-off ported casing apparatus for well cementing
Inventor: BAKER REUBEN CARLTON
IPC: E21B33/16
Filed: 1950-12-04
Abstract: 688,727. Well packers. BAKER OIL TOOLS, Inc. Dec. 4, 1950, No. 29655/50. Class 85. A valve-controlled ported casing apparatus for cementing a well bore, Fig. 1, comprises a tubular member 10 forming part of a conduit string B, C and having a side port 14, a lower inner sleeve valve member 15 disposed initially across the port to close it, and an outer sleeve valve member 31 on the exterior of the tubular member which is disposed initially to allow fluid passage through the port but which is hydraulically shiftable to the port-closing position by fluid fed under pressure through an opening 37, normally closed by a releasably secured upper inner sleeve valve member 45. In operation, with both sets of ports 14, 37 closed as in Fig. 1, cement slurry is pumped directly into the casing string and passes through the-central bores of the inner valve members 15, 45 to be discharged, e.g. from a casing shoe, into the annulus around the casing string. A weighted plug member 51, Fig. 5, is then dropped into the well casing and passes through the fluid therein to seat itself within the bore 50 of the member 15, so that, when pressure is again applied to the fluid, the screws 19 shear thus allowing the valve member 15, to move downwards and open the port 14. During downward movement of the valve member 15, cement below the valve member is allowed to bleed past the seal ring 20 and the stop 25 to the enlarged diameter groove 23. Washing fluid followed by cement slurry is now discharged through the ports 14. To close the ports upon discharge of the required quantity of cement slurry, a top cementing .plug 58, comprising a metalcapped rubber body 70 attached to a fluted - guide. 75, is placed within the bore of the upper inner sleeve valve member 45. When the fluid above the plug 58 is pressurized, the screws 48 shear and the valve member 45 moves downwards to expose'the upper ends of the elongated ports 37 to the fluid which passes therethrough and into the cylinder space 38. The fluid then shears the screws 36 and moves the outer sleeve valve member 31 down to close the ports 14 as shown in Fig. 5. Should well conditions tend. to prevent the member 31 moving down sufficiently to close the port 14, the fluid force on the plug 58 causes the plug and the inner sleeve valve member 45 to move downwards, the force being transmitted to the outer sleeve valve member via the keys 82. The slurry trapped between the members 15, 45 passes out through passages in the plug 51, the passages being initially closed by a valve head retained by a frangible pin.
