Title: Apparatus for raising a stiff horizontal frame
IPC: B66C17/00
Filed: 1965-02-22
Abstract: 1,092,791. Winches. J. H. WIGGINS. Feb. 22, 1965, No. 7553/65. Heading B8B. An apparatus for lifting a stiff assembled frame 13 into position at the top of a perimeter wall 11 comprises a plurality of evenly spaced cables 16 secured at one end to the frame 13, passing over sheaves 17 secured to the top of the wall 11 and having their other ends wound on to winch drums 19, each of which is mounted on a lever 21 pivoted at 22 to the wall 11, the lever 21 being loaded to apply a constant counterbalancing tension to the cable 16 which tension is slightly in excess of that required to balance the relevant portion of the deadweight of the frame 13 and to overcome the static friction of the sheave 17. A switch 27 in circuit with the winch drive motor 32 is connected to lever 21 and if the tension in the cable 16 increases, the lever 21 is lifted and the switch 27 is moved into the off position. With the cessation of the winch drive, the cable tension is reduced and the weighted lever 21 lowers causing the motor to be re-energised. The lever loading comprises a main weight 24 and a fine adjustment weight 26 movable along the lever 21. The static friction of the sheaves 17 may be overcome by an auxiliary winch or additional starting weight at only one of the lever positions. At the top of its travel, the frame 13 rests against a flange 12 on the wall 11 in readiness for fixation. In the embodiment of Fig. 6 (not shown) the lever system extends tangentially to the wall 11. In the embodiment of Fig. 9 (not shown) the winch and its motor are mounted directly on the main weight which is guided for vertical displacement. In the embodiment of Fig. 12 (not shown) the lever is loaded by adjustable tension springs instead of weights. In the embodiment of Fig. 13 (not shown) the spring loaded lever and associated motor switch are mounted on the frame to be lifted. the cable connecting one end of the lever with the winch which is rigidly secured to the outside of the periphery wall, passing over a sheave on top of the wall. In the embodiment of Fig. 14 (not shown), the cable passing from the winch rigidly fixed outside of the wall, is coupled to the frame via a loading spring and carries a winch motor switch operating lug. In the embodiment of Fig. 16 (not shown) the winch and switch operating mechanism are all mounted on the frame to be lifted and the remote end of the cable is secured to a frame at the top of the wall. In the embodiment of Fig. 17 (not shown) a roof and intermediate storey frame are to be lifted. The winch and switch mechanism are mounted on the roof frame and the remote end of the cable is attached to the top of the wall for lifting said frame, whereafter the end of the cable is attached to the storey frame therebelow, which can then be raised.

Patent GB-1011458-A (GB)
Title: Improvements relating to the preparation of epoxy resins
IPC: C08G12/08
Filed: 1964-02-25
Abstract: A process for the production of epoxy resins comprises condensing with formaldehyde a 3-chloro-2-hydroxypropyl ether of a phenol or a N-3-chloro-2-hydroxypropyl aminobenzene, and dehydrogenating the product.  An aromatic hydrocarbon or ether may be co-condensed with the formaldehyde and the 3-chloro-2-hydroxypropyl ether or amine. The condensation product can be further condensed with a polyhydric phenol during the dehydrohalogenation. The initial condensation may take place in the presence of an acidic catalyst and possibly in an acetic acid medium.  The dehydrohalogenation is by means of an alkaline reagent.  The chlorohydrins may be derived from phenol, o-cresol, o-chlorophenol, resorcinol, aniline and N-methylaniline. Many aromatic hydrocarbons and ethers are also specified, whilst Bisphenol A is mentioned as a polyhydricphenol. In one example (IV) the liquid epoxy resin derived from o-tolyl 3-chloro-2-hydroxypropyl ether was exposed to daylight in a glass container for two to three days at room temperature to yield an almost completely crystalline product.  Many of the products are stated to contain a proportion of mono-epoxide.  The epoxy resins produced may be cured by such curing agents as m-phenylenediamine, diethylenetriamine and phthalic anhydride.  The epoxy resins may be used as glues, casting resins, in paints and lacquers and in the production of laminates.

Title: An improved process for the recovery of useful products from used sulphuric acid pickling baths
IPC: C01G49/02
Filed: 1956-03-13
Abstract: Iron oxide is recovered from spent sulphuric acid pickle liquors together with magnesium sulphate (or calcium sulphate produced therefrom) by adding magnesium hydroxide at 160 DEG  F. Preferably an aqueous paste of magnesium hydroxide is mixed into the heated liquor until a pH of 7.2-7.3 is obtained whilst air is blown through the mixture to convert ferrous to ferric hydroxide; thereafter the hydroxide is separated and the magnesium sulphate solution treated with calcium chloride.  This precipitates calcium sulphate and the remaining solution of magnesium chloride may be treated with slaked lime or quenched burnt dolomite to regenerate magnesium hydroxide and calcium chloride, both of which are recycled.

Abstract: 687,860. Root crop harvesters. PACKMAN HARVESTER DEVELOPMENTS, Ltd. June 11, 1951 [March 30, 1950], No. 7916/50. Class 6(iii) A potato or other root harvester comprises a riddle 10 for separating the soil from the roots, the riddling surface being disposed horizontally and barriers set horizontally across the path of the riddle tc break up the soil, the barriers being set at such a height that potatoes will roll over them. As shown, the barrier comprises a horizontal finger 11 provided with an upstanding portion 12 which terminates in a coil 13 attached to a fixed support 16. The finger 11 can be swung to any angular position by loosening a bolt 15. The fingers are made of resilient material and are fitted at spaced intervals over the surface of the riddle. In a modification a boss is mounted on an axle below the riddle and is provided with rubber fingers secured on the boss by means of a circular cage. The axle is mounted with its axis transverse to the stream of potatoes, the fingers projecting through the riddle. In a further modification two sets of notched rubber discs are set one behind the other and rotate on axles set under the riddle. The riddle may be stationary in which case the teeth of the wheels may be used to cause the potatoes and soil to travel over the riddle. The invention may be used on a machine as described in Specification 584,502. It is stated in the Provisional Specification that the invention may be applied to a riddle comprising an endless open mesh band.

Title: Accelerometer pig
IPC: G01B7/34
Filed: 1976-03-01
Abstract: 1508261 Pipe-line pig TRANSCANADA PIPE-LINES Ltd 1 March 1976 [12 Nov 1975] 08043/76 Headings G1G and G1N [Also in Division F2] A pipe-line pig 10 carries shoes 14 including magnetic or sonic inspection devices, an accelerometer (not shown) providing an eleetrical signal indicative of acceleration or deceleration of the pig in the direction parallel to the pipe-line axis and a recorder which records the signals from the inspection device and the accelerometer. The signal from the accelerometer permits identification of out-of-round conditions in a pipe-line since the pig is being propelled by pressure of pipe-line fluid acting on scraper cups (11, 12), consequently such conditions produce an axial deceleration of the pig. Ready identification of an out-of-round condition facilitates interpretation of the signals from the magnetic or sonic inspection devices recorded by the recorder. The shoes 14 are urged against the pipe interior by pivoted arms 17 and springs 19. Alternatively a single annular sensor may be used to inspect the entire circumference. The recorder may also record the distance travelled by the pig or the time for which it has been in operation whereby the flows sensed may be located. The accelerometer uses a resistive strain gauge bridge.
