Abstract: 860,401. Fluid heaters. YUBA CONSOLIDATED INDUSTRIES Inc. July 21, 1958 [Sept. 20, 1957], No. 23295/58. Class 64(1) Gas, oil or other fluid is heated when flowing through similar groups of seriesconnected vertical tubes 30, 31 arranged within an upright cylindrical shell 10 at the lower end of which is a plurality of burners 14, 15, the tubes 30 being disposed around but spaced from the inner wall surface of the shell and the tubes 31 being disposed in a plurality of radially extending banks, and at least one burner being located between each two adjacent banks whereby the tubes 30, 31 are subjected to radiant heat from all sides. In the form shown eighteen of the series-connected tube groups 30, 31 are connected in parallel between an inlet duct 5,2 and an outlet duct 53 for the fluid to be heated. Each tube group comprises one coil section of a multiple-bank preheating coil 37, four of the wall tubes 30 and two of the radially spaced tubes 31. Fluid to be heated is preheated in the coils 37 and flows thence through the wall tubes 30 and then through the tubes 31 before passing to a header 42 and thence to the duct 53. Figs. 6 and 7 show alternative dispositions of the burners and radially extending tube banks. The shell 10 is preferably of steel plate lined with a refractory material.

Title: Improvements in and connected with the treatment of polyvinyl chloride
IPC: C08J7/02
Filed: 1944-11-23
Abstract: Tubes or sleeves of polyvinyl chloride are treated to increase their extensibility by immersing in a suitable ketone, such as acetone, an ester, such as amyl acetate, or a chlorinated hydrocarbon such as di- or tri-chloroethylene or monochlorbenzene. The immersion causes the tubing to swell, enabling it to be passed over an object of enlarged diameter and the volatile liquid is then evaporated off so allowing contraction of the tube around the object.  To minimise the amount of plasticiser which might be dissolved by the volatile liquid, an appropriate amount of the plasticiser, e.g. tri-cresyl phosphate, may be added to the liquid, or, alternatively, it is diluted by the addition of an inert liquid such as water.

Title: Speed limiting systems for internal combustion engines
Inventor: HARRIS PAUL ANTHONY
IPC: F02D17/04
Filed: 1969-02-03
Abstract: 1300741 Automatic speed control JOSEPH LUCAS (INDUSTRIES) LTD 20 Jan 1970 [3 Feb 1969 12 May 1969] 5607/69 and 24056/69 Heading G3R A system for limiting the speed of an internal combustion engine includes means for timing the intervals between successive openings of a contactbreaker or other switching device. If the interval is less than a predetermined minimum value, ignition spark production is suppressed. In the embodiment of Fig. 1, the primary winding 14 of an ignition coil 15 is connected in series with a contact-breaker 16 across the battery 13 of a road vehicle. A thyristor 36 is connected across the contact-breaker. In use, the contact-breaker is opened and closed in timed relationship to the vehicle engine, and each time it opens, a spark is caused at the appropriate plug 21, provided the thyristor 36 is blocked. This will be the case if the engine speed is below the desired limit since a transistor 33 will be conductive to divert current from the gate of the thyristor. After a spark, current through a filter circuit 22-24 will turn off the transistor 33 for a time determined by a resistor 34 and capacitor 32, but this time is arranged to elapse before the next spark is due, so that the thyristor 36 will by then be blocked again. However, if the engine speed is too high, the contact-breaker 16 will open while the thyristor 36 is still gated on, and no spark will result. A second delay circuit 27, 29 ensures that the thyristor is not gated on until the spark has occurred. In a modification, Fig.2 (not shown), the cathode of the thyristor is connected to the positive line to prevent conduction of the thyristor if the engine stalls. The contact-breaker may be replaced by a semiconductor device.

Abstract: 761,244. Telescopic struts; pit props. ONIONS, J. H. Oct. 4, 1954 [Sept. 1, 1953], No. 24114/53. Class 20(2) A telescopic strut such as a pit prop consists of a cylinder 12 and plunger 16, adapted to be extended in light load conditions by means of fluid pressure from a service main or from an external pump, the plunger 16 being surrounded by a frictional clamping ring 34 which rests against the edge of the cylinder 12 and is operable to frictionally clamp the props in an extended position. The actuating fluid, such as compressed air. is supplied to the interior of the prop through a non-return valve 27 in the head 17 of the pluriger. A bolt 19 passes through a hole 25 in a plate 23 at the lower end of the plunger and is screwed into the bottom 13 of the cylinder whereby its head 20 limits the extension of the prop by abutment with the plate 23. The clamping ring 34 carries a friction pad 38 and is formed with lugs 40 through which pass a threaded spindle 44 carrying nuts 42 of opposite hand abutting against the outer faces of the lugs 40. The nuts 42 are held against rotation by a key 46 and the spindle 44 is provided with a non-circular portion 45 engaged by a handle 48 which can be rotated through 90 degrees to tighten or to release the clamping ring. Alternatively the spindle may be rotated by a spanner engageable with the portion 45. The plunger 16 may be tapered, with its larger diameter at the upper end.

Abstract: 880,987. Withdrawing tool for printed circuit panels. GENERAL ELECTRIC CO. Ltd., and WELLS, J. W. R. June 22, 1960 [July 16, 1959], No. 24478/59. Class 61. A tool for withdrawing a printed circuit panel 5 from an associated socket comprises a rigid frame which supports a mechanism and which has two legs 2, 3 that serve to guide the tool into position over the printed circuit panel. The mechanism is operated by pressing down a plunger 4. The mechanism comprises two identical portions each having a cranked lever 6 of which one arm 7 extends down and within a different one of the legs and is provided with a hook-like projection 8 for engaging a slot 9 in the printed circuit panel. The lever 6 is pivoted on one end of a lever 11 which can turn about a pin 12 fixed to the frame. The other end of the lever 11 engages a plate 14 attached to the lower end of the plunger shaft 15. The mechanism is maintained with the plunger 4 in retracted position by a spring 16. A tension spring 18 has one end attached at 19 to the lever 11 and the other end attached at 20 to the cranked lever 6, the latter being prevented from turning about its pivot 21 by a pin 22 fixed to the frame 1. The pressing down of the plunger 4 causes the lever 1 to turn in a clockwise direction about the pin 12, the cranked lever 6 being lifted in anti-clockwise direction about the pivot 21. The resulting movement of the arm 7 causes the projection 8 to engage the slot 9 whereupon the arm 7 engages a stop 29 fixed to the frame 1. Continued lifting of the cranked lever 6 causes movement of the arm 7 in a direction substantially parallel to the side edges of the printed circuit panel to withdraw the panel. The movement continues until the other arm 30 of the cranked lever 6 engages a pin 31 on the frame whereupon the hook 8 disengages from the slot 9.
