Filed: 1972-03-22
Abstract: 1372636 Cleaning coke oven door jambs WILPUTTE CORP 22 March 1972 13491/72 Heading F2N  Apparatus for cleaning coke oven door jambs comprises a rectangular frame, of which the upper half 11, 13, 14 is shown in Fig. 3, elongate carriages 18, 19 carrying scraper blade assemblies 25 being oppositely reciprocable along frame sides 13, 14 for cleaning the vertical sides of the jamb, and upper and lower assemblies 55 (56, Fig. 4) being oscillatable by chains 50 (52) connected to the carriages 18, 19 for cleaning the top and bottom sides of the jamb and the corners between adjacent sides. The carriages 18, 19, Fig. 6, each comprise a box section, having rails 26 and guided by rollers 20, 27. A plurality of the scraper assemblies 25 are fixed to a rotatable shaft 31, carried by the box section. Each assembly 25 comprises substantially perpendicular blades 25a, 25b, urged into contact with respective surfaces of the jamb 35 by springs 43. A spring 37b, Fig. 3, urges each shaft and consequently the blade assemblies to an angular position in which blades 25a are presented towards jamb surface 35a, so that when the apparatus is moved towards the jamb by means, not shown, ends of blades 25a contact the jamb first, further movement then swinging the blade assemblies anticlockwise in Fig. 6 until blades 25b contact the jamb. The upper and lower assemblies 55 and 56, Figs. 3 and 9, each comprise a housing 63a carried by a shaft 60, which is oscillated through chain 50 and sprocket 64. Within and projecting from the housing 63a is a longitudinally movable bar 70, 76, urged to its retracted position by spring 72. The projecting end of bar 70, 76 carries blades 84, 95 and a roller 100, the latter coacting with a track 101 (see also Fig. 3) which corresponds approximately to the shape of the part of the jamb to be cleaned; the extension of bar 70, 76 from housing 63a and thus the position of blades 84, 95 are thereby appropriately determined for any angular position of housing 63a. Positioning of the whole apparatus with respect to the jamb is determined by rollers (130, Fig. 4), midway down frame sides 13, 14 alignment arms 131 (132, Fig. 4) and stops 133 (134, Fig. 4), all of which coact with appropriate formations (not shown) on the jamb. A power-operated latch (Fig. 5) finally secures the apparatus to the jamb. Two fluid-operated piston/cylinders (Fig. 5) impart the oppositely reciprocating motion to the carriages 18, 19. A shield, (Figs. 1, 2, 11-14) protects the apparatus from oven heat.

Title: Improvements in and relating to navigational instruments
IPC: G01C21/16
Filed: 1940-09-03
Abstract: 541,705. Fluid-pressure servomotor control systems. CARCASSON, G. V. PLAUT-. Sept. 3, 1940, No. 13794. [Class 135] [Also in Groups XX, XIX and XXXVIII] A course-recording apparatus for moving vehicles such as aeroplanes comprises inertia members adapted to be actuated by accelerations of the vehicle which accelerations are automatically integrated hydraulically to show the speed, direction of movement, and position and to record the course. As shown in Fig. 1, two inertia actuators A1, A2 are arranged at right angles to one another, the actuator A1 being actuated by accelerations of the aircraft in east and west directions and the actuator A2 in the north and south directions. The actuator A1 is set-back during acceleration during an easterly flight and operates a valve C1 to admit hydraulic pressure to the cylinder 10, the cylinder 11 being open to the exhaust side and consequently the indicator moves easterly over a diagram G marked to represent speed, the position of the indicator being to the east of the centre of the diagram G indicating the direction of movement of the aircraft. When the acceleration dies down and the speed becomes uniform the actuator A1 is returned to central position by the springs B thus cutting off the pressure of the cylinder 10. The pistons 12, 13 are connected to a secondary valve C3 which is opened as shown, permitting fluid pressure to move a piston I1 along the tube H1, the piston 11 being arranged so that a light or shadow beam is thrown on a map and in conjunction with a similar beam operated by the north and south actuator A2 records on the map the actual course of the aircraft. Fig. 2 shows an electric means of controlling the valves C1, C2, &c. positioned at a distance from the actuators A1, A2. The plug of the valve Cl carries a curved soft iron bar 20 embracing a straight bar 21 having a winding 24, the ends of which are connected to slip rings 25 on the shaft of a motor 23 which shaft also carries the bar 21. The motor shaft drives a variable condenser which is part of an oscillator R0 the frequency of which consequently varies between a maximum and a minimum during every cycle. The actuators A1, A2 are mounted on the frame of a gyro-compass and form part of the condensers of two oscillating circuits each containing a lamp 35. At one point in the revolution of the motor 23 the circuit OS will resonate and a current will light the lamp 35 which will affect a photo-cell 36 and by means of an amplifier 37 send a current through the coil 24. The solenoid will thereupon act on the bar 20 to influence the position of the valve Cl. A similar arrangement of the actuator A2 actuates its valve C2.

Title: Arrangement for compensating axial thrust in motors which are built together with a liquid centrifugal pump
IPC: F04D13/06
Filed: 1927-05-25
Abstract: 272,480. Maschinenfabrik Oerlikon. June 9, 1926, [Convention date]. Balancing moving parts; pumping-machines.- A centrifugal pump for a liquid that circulates. behind and in front of the impeller mounted on the motor shaft is provided with a single slot 10 on the suction side between the rotor and its casing, the slot being variable in width and adapted in conjunction solely with the normal peripheral clearance gap between the rotor and casing automatically to effect the equalization of the axial thrusts before and behind the impeller. The liquid passes from the suction inlet 3 to the impeller 2 and into the outlet 1. Part of the liquid flows from the slot 4 through the slot 10 to the pump inlet 3, and another part flows from the slot 4 into the motor casing 5 and returns from thence through the hollow shaft 6 to the inlet 3. An axial thrust exerted on the impeller that moves it sideways in the direction of the motor causes the opening 10 to be enlarged. The pressure in the chamber 11 then begins to be lowered, since the slot 4 acts as a throttle for the incoming liquid. The widening and lessening of the slot 10 is effected automatically in response to changes in the axial pressures, and the axial thrusts on the impeller are balanced.
