Title: Improved process and apparatus for continuous catalysis
IPC: B01J19/24
Filed: 1946-05-10
Abstract: Colophony is decarboxylated by circulation through a closed circuit at 250 DEG  C. in contact with a 2 per cent by weight solution of phosphoric acid.  The gases are condensed outside the circuit and pinoline subsequently recovered <PICT:0655603/IV (b)/1> from a pinoline acid water separator.  The decarboxylated material is extracted from a continuous decanter J.ALSO:Continuous catalysis in the liquid phase is characterized by the charge being continuously introduced into an inert liquid which is violently agitated whilst being circulated in a single closed circuit and which contains the catalyst, the products being removed from the circuit.  The products are decanted hot at K by a device J located within an oil-jacketed tank B wherein the reaction is completed.  In operation, rosin is melted and passes through a tube D into an injector C where it contacts decarboxylated oil-the inert liquid-containing 2 per cent by weight phosphoric acid, which has been sucked by pump A from the bottom of the tank B.  Baffles G in an oil-jacketed column E keep the liquid agitated.  Gases pass out through a dephlegmator H into a separator I.  The extraction of the decarboxylated oil <PICT:0655603/III/1> through K is regulated by a float M.  Shale oil is treated with aluminium chloride to produce a prime oil; and gasoline is refined with aluminium chloride.

Title: Improvements in and connected with electrical systems for heating fluids in pipes and in containers
IPC: F24H1/10
Filed: 1941-11-05
Abstract: 552,591. Electrically heating liquids. CRITTALL & CO. Ltd , R., and ADSHEAD, B. Nov. 5, 1941, No. 14230. [Classes 39 (iii) and 75 (i)] Oil is circulated by a pump 1 in a closed system 2 and is heated by passing a current through the pipe which may be connected to the secondary of a step-down transformer 5. Pipes 6 leading the oil to a burner 3 are in parallel across an insulating section of pipe 13 and are electrically in series with the pipe 2. Alternatively, one pipe is arranged within another to form the electric circuit, or the current may flow through a single pipe and return through another pipe or conductor. The heating effect is greater in the pipes 6 than in the pipe 2. The oil temperature may be controlled by a thermostat 7 acting on a switch 8 across the insulating section 13. Variations in the total resistance may be compensated by employing suitable tappings on the transformer 5. If a single branch pipe to the burner is employed, the oil temperature may be controlled by a thermostat governing the supply of cooling air to the annular space between the outer current-carrying pipe and the inner oil carrying pipe. A separate transformer may be employed for each burner branch. The oil temperature in the main pipe may be controlled by a thermostat controlling the transformer. The oil system may be drained to the storage tank by reversing the pump, or by valves 11 to a sump. The pipe may be immersed in a container to heat the liquid therein.

Title: Sheet feeding mechanism
IPC: B41J13/00
Filed: 1943-09-02
Abstract: 571,480. Feeding sheets; typewriters. WILLIAMS, W. P. (Standard Register Co.). Sept. 2, 1943, No. 14364. [Clasaes 100 (i) and 100 (iv)] Sheet-feeding apparatus which is especially applicable for feeding record units comprising one or more sheets to typewriters, or other machines such as addressing-machines, is constructed with an inclined magazine 8 in which the sheets 14 are stored and are pressed by a spring 8<1> so as to cause the front edges of the sheet to engage a retaining lip 11. The sides 12 of the magazine are adjustable laterally. The sheets are fed in succession to the platen 2 by means of adjustable ejector fingers 23 on a shaft 17 rotated counter-clockwise by changeable gearing from a gear on the platen 2. The fingers withdraw the front sheet from the lip 11 and thus permit it to fall by gravity so as to engage stops 26 carried adjustably by slides 27 which are reciprocated by a cam 38 so as to move the slides radially of a feed roller 37 driven from the platen roller. The separated sheet drops when a roller 36 carried by the slides 27 is moved away from the roller 37, and in this position of the roller 36 the stops 26 are in the path of the sheet, which is held thereby until the preceding sheet is cleared. The roller 36 is then moved to engage the roller 37 and the stops 26 move clear of the sheet. Guides 24, 46 guide the sheet to registered position. The sheet is fed through the typewriter by rollers 40 coacting with the platen 2, and is finally fed away by a roller 45 to a shoot 41<1> formed of parallel plates 42, 43 carried by arms 44 journalled on the shaft 17.

Filed: 1956-05-09
Abstract: 801,084. Vehicle power steering. FORD MOTOR CO., Ltd. May 9, 1956 [May 18, 1955], No. 14364/56. Class 79(5) [Also in Groups XXIX and XXXIV] A motor vehicle having a number of hydraulically power actuated components including, for example, steering devices, has a hydraulic system providing a common source of pressure for the components. A low pressure pump 11 supplies liquid through a line 12 to a low pressure cylinder 63 of an intensifier 14, high pressure cylinders 64, 66 of which discharge through check valves 73, 74 to a line 16 supplying a power steering mechanism 18 and other hydraulically actuated components 17, 19. As shown, liquid is supplied from line 12 through a line 109 to the right hand end of the cylinder 63 to move an intensifier piston 69 to the left; high pressure liquid being discharged from cylinder 64, and low pressure liquid entering cylinder 66 past a valve 72. At the end of its stroke piston 69 opens a valve 78 and liquid passes from a line 86 through a line 87 to move a valve 91 to the right against the action of a spring 97. This opens a passage from line 12 through a line 98 to the left hand end of a valve 92 to move it to the right against the action of a spring 104. A line 108 is thus connected to line 12 and line 109 is opened to exhaust so that piston 69 begins a return stroke. At the end of the return stroke a valve 79 is opened, allowing the liquid trapped in line 87 to pass to exhaust and springs 97, 104 to return valves 91, 92 to the position shown. A gas-loaded-piston type accumulator is connected to line 16 and provides an immediate supply of pressure liquid for actuating the components 17, 18, 19. Closed-centre valves control the actuation of components 17, 18, 19 so that when none of the components are being actuated there is no flow through the supply line 16.

Title: Speed-programmed friction welder control
IPC: G06G7/28
Filed: 1969-03-20
Abstract: 1,254,022. Welding by pressure. CATERPILLAR TRACTOR CO. 20 March, 1969 [25 March, 1968], No. 14741/69. Heading B3R. [Also in Division G3] A friction welder with an hydrostatic transmission to the rotating chuck, as disclosed in Specification 1,194,876, comprises a variable displacement pump 10, driven by an electric motor 12, with a fluid connection 93 to a variable displacement motor 11. The displacement settings of the pumps and motor are controlled by an electrical control system utilizing a programmer 70 generating an amplitude-modulated speed versus time signal comprising a time signal generating circuit the output of which is modulated by a signal from a speed function generating circuit. It is stated that the programmer could also comprise a computer using a punched tape programme. The output of the programmer 70 is fed to a logic circuit 71 that receives a speed signal from a tachogenerator 25 driven from the motor 11. The logic circuit incorporates an OR-gate responsive to the speed signal and a set bias signal to pass the higher of the signals to a cam angle controller 81 for the motor 11, positional feedback being derived from a circuit 78 at a summing junction 80, and a null value, representative of a desired initial or zero speed, at a summing junction 75 from a circuit 76. The logic circuit also incorporates an AND-gate which compares the speed signal with a set value and feeds the smaller signal to a cam controller 86 for the pump 10, positional feedback is fed to a summing junction 85 from a circuit 87 and a null signal, for adjusting the pump for the desired initial conditions, is fed from circuit 83 to a summing junction 82. The logic circuit thereby varies the displacement of the pump while maintaining the displacement of the motor at a maximum for low speeds and reduces the displacement of the motor and maintains the displacement of the pump at a maximum for high speeds. The programmer also supplies a desired speed signal to a circuit 91, comparing this signal with a bias signal from a weld complete circuit 90, whereby at the completion of a weld cycle a dump valve 92 is opened to shut-off the flow of hydraulic fluid to the motor. In a modification, where the displacement of the pump is sufficient to supply the motor at all speeds the logic circuit is omitted and the programmer solely controls the displacement of the pump.

Abstract: 528,950. Hydraulic transmission of power fluid-pressure servomotors. MASCHINENFABRIK AUGSBURG-NURNBERG AKT.- GES. May 17, 1939, No. 14792. Convention date, May 17, 1938. [Classes 69 (ii) and 135] A hydraulic coupling in which the gear automatically adjusts itself to variations in load is constructed with a pump which delivers fluid at a uniform rate and a hydraulic motor provided with means to adjust the working space of the motor against the action of a constant force and which is acted upon by pressure of the fluid delivered by the pump. Fluid from the pump passes from a pipe 1 to the hydraulic motor which comprises a rotor 4 with sliding vanes 5 mounted on a fixed axis and an eccentric casing 3 capable of sliding in a fixed casing 2 to vary the output of the motor. The position of the casing 3 is controlled by the action of a spring 6, which is adjustable by a screw 11 and counteracts the pressure on the casing 3 of a rod carried by a piston 7 which is in a cylinder connected to the inlet pipe 1 and outlet pipe 10 of the motor. The motor's speed is inversely proportional to the load. In a modification the position of the casing 3 is controlled by a servomotor system which acts as an automatic control permitting either pipe 1 or 10 to act as inlet or pressure pipe. As shown the pipe 1 acts as inlet pipe and on increase of pressure in pipe 1 a piston valve 33 permits the fluid to pass so that it can act on a piston 20 fixed to a rod 22 on which are other pistons 18, 19, the piston 18 being fitted with a spring 21 which normally maintains the rod 27 in the position shown. On the motion of the rod 27 to the left the fluid passes via passages 23, 28 and acts on the left side of the piston 31 and moves the casing 3 to the right. The piston 19 also uncovers an outlet port 25 of a pipe 26 leading back to the oil container of the pump. When the pipe 10 acts as the pressure side of the motor the piston 35 moves to the right under the action of the fluid pressure and the fluid can enter via passage 36 and the control of the motor is effected in the same way as when the pipe 1 is the pressure pipe.

In a reciprocating pump, a number of pump cylinders are arranged around, and parallel to, the driving shaft 2 that carries a cam 5 that gradually moves the pistons 9 during the suction stroke but has a shoulder to permit springs 10 to make a sharp delivery stroke. The pistons 9 are stepped to form pumping chambers 18 and have axial bores 17 connected to radial bores 16. During the latter part of the suction stroke, the pumping chamber is filled through these bores and during the early part of the delivery stroke, liquid is returned through the bores until the radial bores 16 are closed by the smaller part of the cylinder when liquid is delivered to one of the outlets 15; the return flow in the early part of the delivery stroke assists to clean a filter in the pump suction. The cam 5 has a step 6 on the other side that is engaged by a spring-pressed plunger 3 carried by the shaft 2 so that the drive is transmitted to the cam when the shaft 2 is rotating in one direction only. The pump may have a single cylinder.
