[Also in Division B8] The forwardly extending legs 27 of a masted lift truck are provided with castors 25 and are secured to uprights 28 pivoted at 29 to a frame 30 and connected by links to a hand lever 39, whereby the angle between the legs 27 may be varied. The lever 39 is secured to a bar (36), Figs. 2, 3 (not shown), which is pivoted to the frame 30 and which is connected by links (33) to arms 32 secured to the uprights 28. In a modification, Figs. 4, 5 (not shown), toothed sectors (61) secured to the legs (58) mesh with toothed sectors (62) secured to shafts (63) which are rotatable by hand levers (68). A vertically movable wheel (107) is provided whereby the wheels (52) may be raised from the ground. Oscillation of the levers (68) about the axis (67) causes the truck to be moved forwards or backwards depending upon the position of a push rod (95) which is coupled by links (91, 89) to a reversing member (85), Figs. 6, 7 (not shown). L-shaped members (71, 81) are loosely supported on the axle (51) of each wheel (52) and are interconnected by bolts (77) extending through tubular distance-pieces (74, 75). The reversing member (85) is pivoted at (84) to the member (81) and is formed with teeth (86, 87) adapted to engage the distance pieces (74, 75) which are housed in recesses (78, 79), Fig. 8 (not shown), in a hollow member (80) which is connected by a link (103) to the lever (68). When the reversing member (85) is moved about the pivot (84) from the neutral position shown, one of its teeth disengages from and the other engages in the recesses (78, 79) and, on reciprocating the lever (68) about the axis (67), the member (80) pivots about one of the distance-pieces (74, 75) into engagement with the side wall (70) of the wheel (52) which is thereby rotated.

Title: Improvements in carburettors for internal combustion engines
IPC: F02M9/08
Filed: 1921-04-22
Abstract: 183,556. Nayler, T. A. April 22, 1921. Spray carburettors.-A carburettor comprises a barrel throttle e which is shaped to form with the walls of the induction pipe and float chamber a choke-tube of variable section. Two tubes l having opposed slits so as to spray in opposition to one another are arranged at the throat of the passage and communicate with a chamber h supplied from the float chamber through an adjustable valve k. The float chamber and induction pipe are secured together by a single nut c, through which the valve k passes. The throttle e has a groove m, the end of which is engaged by a trigger n to limit the closure of the throttle during normal working, but at starting the trigger is withdrawn by a Bowden wire and the throttle turned into the position shown in Fig. 7. In this position the normal inlet is practically closed and the opening to the induction pipe is on the side remote from the normal opening, the resulting reduction of pressure causing a rich mixture to be formed. The mutual interference of the jets tends to prevent the formation of an over-rich mixture at high speeds, but additional air may be supplied through one or more ports controlled by screws o. The lower part of the air intake and throttle passage is rectangular in cross-secfion and the upper part of the passage circular.

Filed: 1938-04-19
Abstract: 498,987. Safety cut - - off devices. FRIEDMANN, L., (trading as FRIEDMANN, A., [Firm of]). April 19, 1938, No. 11718. Convention date, April 27, 1937. [Class 135] A safety cut-off device for isolating a defective part of an hydraulic transmission installation comprises a plurality of upwardly directed channels such as 1, 1a, having seats 2, 2a, for valves 3, 3a and at their lower ends stops for the valves. Adjacent the seats are passages 6, 6a, leading to the working cylinders of the installation, and a passage 4 that is in permanent connection with a source of pressure. At their lower ends the channels are in open communication with one another through a passage 7. In operation fluid from the passage 4 traverses the channels 1, 1a with which the working cylinders communicate through the passages 6, 6a. Should a fault develop, the fluid will rise in the affected channel at a faster rate than the normal, thus closing the appropriate valve on its seat and cutting out the faulty part of the installation. Screwed pins at the top of each channel serve to push a valve from its seat when the fault is corrected.

Title: Improvements in or relating to the distillation of dichlorobutadiene
IPC: C07C17/38
Filed: 1948-05-04
Abstract: 2,3-Dichlorobutadiene is distilled through a fractionating column in the presence of methanol in such amount that there is at least 30 per cent of methanol (based on the combined weight of dichloro-butadiene and methanol) at each section of the column; the temperature at the top of the column is maintained 0.5 DEG  to 3.0 DEG  C. below the boiling point of methanol; and a vapour mixture, approximating to the azeotropic composition, of dichlorobutadiene and methanol, is withdrawn at the head of the column.  The process enables dichlorobutadiene to be obtained with minimum polymerization and free of contaminants from a reaction product, e.g. that given by the dehydrochlorination of tetrachlorobutane or of trichlorobutene.  The boiling-points of the dichlorobutadiene/methanol azeotrope at various pressures are presented on a graph, which also shows that the azeotropic composition does not depart far from 50 per cent methanol for the range 275 to 760 mm. Hg absolute.  In an example, 112 lb. of tetrachlorobutane and 225 lb. of methanol were charged to a still-pot surmounted by a column (4 inches X 40 inches) packed with vertically-arranged glass fibres and provided with a reflux condenser.  There was then fed into the pot 118 lb. of aqueous sodium hydroxide (50 per cent) at such a rate that the vapours evolved by the heat of reaction had a velocity of 5 ft. per second in the column.  During most of the run the temperature at the top of the column was maintained at 62.5 DEG  C.; but towards the end it was gradually raised to 63.5 DEG  by supplying heat to the pot. Dichlorobutadiene was separated from the distillate by addition of water.  In another example, a mixture of dichlorobutadiene (17 per cent), methanol (53 per cent), water (20 per cent), and miscellaneous organic impurities (10 per cent) was introduced into a glass fibre-packed column (10 feet high and 6 inches diameter), at a point 6 feet from the top.  The temperature at the top was maintained at 62.5 DEG  C., and that in the reboiler at 75 DEG  C.  The dichlorobutadiene recovered from the distillate by dilution with water comprised 93 per cent of that in the feed.
