Title: Improvements in water lifting apparatus
Filed: 1926-09-27
Abstract: 272,366. Polson, W. R., and Evans, H. C. Sept. 27,1926. Vacuum apparatus. - Apparatus for raising liquids comprises two chambers 5, 6 connected by pipes 30, 31 to the liquid supply and by pipes 40 to an intermittently operated valve 59 controlling the alternate admission of suction and atmospheric pressure to the chambers. When a chamber is full, a float valve 46 closes the end of the pipe 40 to prevent liquid from entering the pipe. The suction is produced by a pump 10 which exhausts air from a chamber 3 communicating with the valve casing by a pipe 77. The valve has two through ports 65, 66 so arranged that when the port 65 connects one pipe 40 to suction through a passage 73 and pipe 77, the port 66 connects the other pipe 40 to atmosphere through a branch pipe 52 and a port 71. Thus while one chamber 5 is filling, the other is discharging through an automatic valve 23. The crankshaft 18 of the pump drives the valve through gearing 88, 87, 90 and a tumbler lever 91 engaging arms 82 on the valve spindle. In another form, the valve is operated by floats in the chambers 5, 6 through a flexible connection on a winding drum, and a tumbler lever engaging arms on the valve spindle. The pipes 52 for admitting air may be replaced by channels in the valve casing. The chamber 3 may be omitted.

Title: Improvements in or relating to continuous processing furnaces
IPC: F27B9/22
Filed: 1953-08-31
Abstract: 743,038. Continuous furnaces for heat treating granular materials. CARPENTER, G. May 18, 1954 [Aug. 31, 1953], No. 23955/53. Class 51 (2). A continuous furnace for heat treating expandable materials such as vermiculite, perlite or shell clays, comprises a refractory lined tunnel 11 with a burner 12 extending along its base, a reciprocating roof 13 supported on ball or roller bearings 14 and provided with a sand seal 18, a trough 20 of heat-resisting steel or refractory material fixed to end walls 21 of the furnace, and an assembly of scraper blades 22 which are raised and lowered into the trough periodically, so that, combined with the horizontal reciprocations of the roof, these movements cause charge material fed into the trough at one end to be traversed through the furnace. The roof is assembled of transverse refractory blocks on rods 16 and is driven from an electric motor through a main shaft 35 carrying a disc 50 and a connecting rod (not shown). The scraper blades 22 are carried by uprights 23 extending through the roof and attached to a framework having longitudinal members 25 and uprights 26 slidable on uprights 27 of a framework attached to the roof. Vertical movement of the scraper blades is produced by rollers 33 engaging the horizontal members 25 and attached to pairs of discs 32 rotated in opposite directions by bevel and sprocket gearing from the main shaft 35. Movements of the roof are synchronized with those of the scraper blades, so that, as the roof moves forwardly, the blades are in the lowered position, i.e. the rollers 33 are not engaging the horizontal members 25. Material adhering to the scrapers is removed by contact with the roof slots through which the blades extend. Charge material is fed through a shaft 52 over staggered plates 53 on to the trough 20, the shaft acting as a chimney for the waste gases and a preheater for the charge material. In a modification, Fig. 4 (not shown), the furnace has a fixed roof and a frame carrying the scrapers extends through the furnace, through the doors and over the top of the furnace, and is oscillated cyclically to move the charge material along the trough. The trough may also be oscillated longitudinally and the scrapers raised or lowered in synchronism with such oscillations. Specification 693,168, [Group V], is referred to.

Abstract: 462,234. Motor vehicles; changespeed gearing. MORGAN, H. R. Aug. 27, 1935, No. 23980. [Classes 79 (ii) and 79 (iii)] [Also in Group XXIV] The engine A, Fig. 1, drives the differential gear f<2> or axle shaft through a constant-mesh changespeed gear comprising transverse shafts C, F, a universally - jointed shaft L, and a second transverse constant-mesh change-speed gear comprising shafts c<1>, f<1>. In the construction shown in Fig. 1, the first change-speed gear provides for two forward speeds by means of gear trains D, E and d<1>, e<1> controlled by a clutch H, a reverse speed being obtained by means of a gear train d<2>, d<3>, e<2>. A synchronizing device is provided at I. The second change-speed gear provides two forward speeds. The shaft L is provided with a telescopic joint at l<1>. In the construction shown in Fig. 3, in which the engine is too long for the arrangement of Fig. 1, the engine A is arranged askew, and the change-speed gears D &c. are bevel gears. The two change-speed gears may be conjointly controlled by a preselector device as shown in Fig. 2. The clutch fork Q of the first two-speed gear is operated by a rock-shaft P having arms p<2>, p<3> jointed to rods r<1> R sliding in a fixed guide T. The clutch fork q<1> of the second two speed gear is operated by a rock-shaft p<4> having arms p<6>, p<7> jointed to other rods r<2>, r<3> also sliding in guide T. Any two adjacent rods may be operated by a slidable member U which is first rotated to select the two rods it is desired to operate. The member U is fixed to a square or like shaft u<1> sliding in a rotary sleeve V formed with teeth v<1> engaged by a gear quadrant X. When the quadrant is rotated by the preselector control lever (not shown) and a link Z the member U is rotated to the desired position. When the member U and its shaft u<1> are moved axially the two rods selected are moved back and the rock-shafts P, p<4> are rotated in one direction or the other to put the selected gears in operation. If one clutch fork is already in the desired gear position its rod is not affected by the sliding movement of member U. The shaft u<1> and its member U are connected by a joint u<3> and a rod u<2> to a lever which may be the usual clutch control. The second change-speed gear may drive the axle through reduction gearing. The engine A may be of V-type as shown in Fig. 5, with its crank-shaft at a higher level than the axle shaft f<3>.
