Title: Valve for clutch control in a wheeled vehicle
IPC: F16D67/04
Filed: 1956-12-10
Abstract: 799,817. Controlling clutches and brakes. CLARK EQUIPMENT CO. Dec. 10, 1956 [Dec. 15, 1955], No. 37626/56. Class 80 (2). A valve for use in an industrial truck having pressure fluid engaged reverse and forward drive clutches 14, 15, comprises a spool-shaped valve piston 16 to one end 29 of which pressure fluid passes from an inlet pipe 11 through a leak passage 33 to push the spool against coaxial compression springs 17, 18 controlled by the service brake pedal 20 of the truck, depression of the pedal to apply the brakes reducing the bias of the springs 17, 18 so that the fluid pressure at 29 can move the spool 16 rightwards to close a passage 12 through which fluid is supplied to the clutch engaging mechanism. Simultaneously, a pressure relief pipe 22 leading to a sump is opened, some of the fluid passing through the pipe 22 being diverted to lubricate the selecting mechanism of the reverse and forward clutches 14, 15. A manually operated forward-reverse selector valve 13 directs fluid under pressure from the pipe 12 to either a pipe 48 or a pipe 49 leading to the reverse and forward clutches 14, 15 respectively. A by-pass passage 54 bleeds off fluid from the space 29 at the back of the valve spool 16 to the pipe 12, so that the operating mechanism of the clutches is always full of fluid and the valve spool 16 can move rapidly leftwards to engage the selected clutch when the brake pedal 20 is released.

Title: Process for recovering tar phenols and bases from coal tar distillates containing the same
Inventor: HOLDSWORTH ERNEST CLIFFORD
IPC: C07C37/00
Filed: 1961-10-20
Abstract: In recovering tar phenols and organic bases from coal-tar distillates containing them, the distillate is first diluted with a quantity of the same or a similar distillate from which tar phenols and organic bases have been removed, whereafter the bases are washed out with a mineral acid and finally the tar phenols are removed.  In the first step the distillate is preferably mixed with such a proportion of phenol-and base-free distillate as to yield a mixture containing 2-15% of tar phenols.  The extraction of bases from the mixture is carried out in a number of stages or in counterflow, suitably with aqueous sulphuric acid of 2-20% concentration, and the bases may then be purified by washing with a coal-tar distillate from which bases and tar phenols have been removed.  The final removal of tar phenols from the original distillate may be effected with caustic alkali or by extraction with aqueous methanol. Examples are given.

Abstract: 1,113,699. Calculating device. W. F. BRAUN. 26 Aug., 1966 [2 Sept., 1965], No. 38364/66. Heading G4B. A device for calculating functions of the form and in particular for finding the exponent x given two pairs of values (P 0 , K 0 ), (P 1 , K 1 ), comprises two plates mounted in a frame, a first plate A carrying a logarithmic graph of the values of P and K, and the second plate B carrying a family of parallel straight lines. In a first embodiment, as shown, the plate A is movable such that the axes of the logarithmic graph remain parallel to their initial directions, while the plate B is rotatable about a point D of one of the family of straight lines. To perform a calculation the pairs of readings (P 0 , K,), (P 1 , K 1 ) are marked (1), (2) on the graph, and both plates are then moved until one of the straight lines passes through both marked points (1), (2). The slope of that line will then correspond to the value of the exponent x which may be read off from a scale X marked on the frame, and along this line new pairs of values (P, K) corresponding to the same exponent may be read off from the logarithmic graph. In a second embodiment (Figs. 2a and 2b, not shown), the plate A is fixed in the frame, while the plate B rotates about a plate (E) which is free to slide in a direction parallel to that of an axis of the graph of plate A, the plate (E) also carrying the exponent scale X. In a further embodiment (Fig. 3, not shown) tolerance limit lines are provided on plate B so that given one pair of readings (P 0 , K,) and a value for x, then tolerance limits for further pairs of values (P, K) may be found.

Filed: 1968-08-12
Abstract: 1,242,251. Electron beam apparatus. HIGH VOLTAGE ENG. CORP. 12 Aug., 1968, No. 38505/68. Heading H1D. [Also in Division H2] In a column of electrically separated coils (3, Figs. 1, 6, not shown) adjacent pairs are magnetically coupled, a known frequency (e.g. 10 kc/s.,) alternating current is applied to one coil, and all coils are tuned by respective capacitors to a frequency of the same order as the input frequency so as to produce a phase shift between the currents in successive coils, whereby a waveform (Fig. 2, not shown) representing magnetic induction in (or voltage across) each coil effectively travels along the column. Each coil (3) has an oppositely wound auxiliary coil (4) around it to confine the magnetic field, the two coils being potted (8). Each coil unit (3, 4) has an associated rectifying and voltage doubling circuit the outputs of which are connected in series between high voltage output terminals, and the components of which are housed in hollow rings (15). A resistance (18) linearizes the voltage drop between the H.V. terminals, which supply an accelerator tube (16). Ferrite discs (5, 6) confine the flux at the ends of the column. The H.V. output has a very low ripple due to the travelling wave effect. Reflections at the ends of the column (which would produce undesired standing waves) are prevented either by a power absorbing resistor (19) across the end coil, or by arranging a second column of coils (35, Fig. 7, not shown), having no rectifier circuits, so as to produce a signal (at 40) of the same phase as the input (37) to the first column, and by feeding back this signal via a transformer (41) to conserve energy. In a further embodiment, Figs. 8, 9, the accelerator tube 45 is arranged in the middle of the column, a second auxiliary screening coil 48 being added inside each main coil 46; and four such sets of coils are potted into one unit, cavities 43 accommodating the circuit elements. A plurality of these units can be stacked as required. Cooling ducts may be provided in all embodiments.

Title: Continuous annealing method and apparatus
IPC: C21D9/56
Filed: 1962-10-12
Abstract: In a process and apparatus for the continuous heat treatment of metal strip, the latter is first preheated by passage through a furnace operating at a temperature below the lower critical temperature of the material, and is then raised to the desired treatment temperature by passage through an induction coil.  The strip tensioning means may be so arranged that the tension required for passage through the preheating furnace may be removed from the strip before it is raised to the higher temperature of the induction zone.  The latter rapidly-adjustable temperature may be controlled in response to a strip temperature-sensing means, so that arrest of the strip does not result in overheating.  As illustrated in Fig. 1, strip leaving coil 2 is preheated <PICT:0974774/C6-C7/1> in furnace 8 which is radially heated, and passes therefrom through induction heating means 11 located within the furnace shell and controlled by sensing means 12. Strip gripping means 5, 6 located at each end of the preheating zone have their relative speeds controlled by means 7, whereby the appropriate tension for passage of the strip through that zone is maintained therein, but removed prior to passage of the strip through the high-temperature zone.
