IPC: D03D27/06
Filed: 1925-06-05
Abstract: 255,200. Crabtree, D., and Crabtree, T. H. June 5, 1925. Pile-fabric looms. - The pile is formed by means of hooked rods or bars 2, Figs. 4, 5 and 6, mounted side by side on a rack bar 3 fixed to a sliding bar 5, which is caused by cam-controlled lever mechanism to move on the breast beam 6 and thus move the rods &c. 2 towards and away from the reed. The upper edges of the parts b of the hooked rods &c, 2 are engaged by a grooved upper bar 4. which is caused to slide longitudinally on the bar 3 at times to tilt the rods &c. 2 from vertical to inclined positions when the rods have been moved towards the reed, thus enabling the hooked parts a of the rods &c. to engage the warp threads and cause them to form loops over the rods as these move away from the reed. The loops slide over the rods &c. as the wefts are beaten up and ultimately are cut by the lower edges of detachable cutting blades 22 held in grooves in the rods &c, by cross pins 23<a> or by the upper edges 22, Fig. 7, of cutting blades embedded in the rods &c. To prevent accumulation of fluff &c. in the grooves of the rods &c., a bar formed with projections may be reciprocated in openings therein. The rods &c. are formed with notches b' to engage a flange from an extending rib 3d fixed to the bar 3. This rib 3d may be made in sections, so that after removal of any one section, any of its respective rods &c. may be removed. A bowl &c. on a lever actuated by cam-controlled lever mechanism engages a slot in the bar 4 and thus causes the bar to move longitudinally on the bar 3 to tilt the rods &c. 2 at the desired times. The second Provisional Specification describes an arrangement wherein the hooked rods or bars engage openings in two or more rods extending across the loom, one of which is moved longitudinally by cam lever or other mechanism.

Title: Improvements in or relating to transmitters for control or/and indicating systems operating by variation of fluid pressure
IPC: F15B5/00
Filed: 1951-06-22
Abstract: 690,601. Fluid-pressure servomotor-control systems. BAILEY METERS & CONTROLS, Ltd. June 22, 1951 [June 22, 1950], No. 14874/51. Class 135 A mechanism for producing a fluid pressure bearing a functional relationship to the movement of an input member 17, Fig. 2, comprises a floating lever 55 connected to the member 17, to the end of the longer arm 57 of a bell crank lever which lies alongside it, and through a link 65 to a pilot valve 44, and a bellows 50 extending alongside the arm 57, abutting at its free end against the spring-loaded shorter arm 51 of the bell crank lever, and subject through a duct 52 to the output pressure of the system, the arrangement being such that a change in output pressure consequent on a movement of member 17 acts through the bellows 50 to tend to return the pilot valve to the null position. The invention may be applied to a 'system wherein a variable causes a transmitter 15, Fig. 1, to produce a control pressure which is applied both to a diaphragm motor 13 actuating a valve to regulate the variable and to a bellows motor 10 actuating an indicator 8. The value of the variable at any moment is shown on an indicator 5. The variable may be a fluid flow or pressure, a temperature or humidity, or a manual control movement. The movement produced by the variable is applied to lever 17 which, through an arm 53, link 54, floating lever 55, and link 65 carried by an arm 63 projecting from lever 55, actuates the piston valve 44 controlling the supply of a pneumatic pressure from a line 22 to the output line 7 or the exhaust of line 7 to atmosphere. Duct 52 which communicates with line 7 is a capillary and the end thereof inside the bellows is twisted to prevent the issuing jet from impinging on the free end of the bellows. The latter is loaded by a spring 66 carried by an adjustable hinged plate 67 and the free end is carried by the vertical arm of lever 51 which is pivoted on a spring strip 59. The horizontal arm of lever 51 carries the pivot 56 of the floating lever 55 so that, after the piston valve has been moved to produce a controlling or indicating pressure, it is returned after an interval to the null position by the movement of the bellows due to the altered pressure reaching the interior of the latter. The operative land of valve 44 is sharp-edged and it co-operates with square ports in a sleeve 35, and the valve stem also carries a rounded sealing land 45 at its lower end. The sleeve can be adjusted in position by means of an eccentric cam 71 which acts on an L-shaped lever 38 supporting the lower end of the sleeve. Lever 38 can be swung aside to give access to the sleeve, etc. for cleaning purposes.

IPC: B41F23/06
Filed: 1927-06-07
Abstract: 272,158. Horn, T. W. June 7. 1926. [Convention date]. Sheet-separators ; pile supports; sheet-guides.-In a rotary duplicating or like machine, slip sheets S are interleaved between the printed sheets P in the delivery receptacle 7 by feeding the slip sheets from a magazine 8 above the printing- couples 2, 3, in such a manner that there is no movement of the sheet S over the surface of the sheet P. The sheets P are fed in known manner from a table 5 and are delivered at twice the speed of the sheets S, there being an interval corresponding to about half a rotation of cylinder 2 between the feeding of successive sheets P. During this interval a sheet S which is guided by curved guides 32 reaches the pile in receptacle 7, and pivots about its end A and falls on to the previously delivered sheet P without sliding over its printed surface. The sheets S are fed from magazine 8 by a friction belt 14 passing round rollers 15, 16, 17; double feed is prevented by a pivoted follower 19, and a friction flexible wiper 20 with a metal bar 21 along its forward edge. The wiper 20 is mounted on a crank-arm 22 pressed by a spring 23. The shaft of roller 15 is driven from the printing-couple by sprocket and spur gearing, one of the spur gears being coaxial with a pivot 10 about which an extension 9 of the magazine 8 pivots, so that the magazine can be pivoted out of the way of the printing- couple to allow access thereto. The pivot 10 is carried by arms 11 secured by clamps 12 to the frame of the printing-couple, and pins 13 bearing on the arms 11 retain the magazine in its operative or inoperative positions.

Abstract: 1367934 Machine tool control MARTONAIR Ltd 9 May 1972 [18 May 1971] 15454/71 Heading B3B [Also in Division G3] A method of detecting the position of one or more movable elements 13 of a machine, e.g. a machine tool, to enable the or each element to be controlled, comprises transmitting coded fluid pressure wave pulses through waveguide means 15 to one or more outlets 14, the or each of which is occluded in one position of an element 13 and is unobstructed in another position of that element whereby the element 13 controls the emanation of a pressure wave signal 35 as a non-directional signal which permeates the atmosphere, and detecting the emanation of the or each pressure wave signal 35 with a receiver arranged in a position independent of the outlets to produce an output which varies according to the position of said element. The method uses a pneumatic supply to a transmitter 16 which produces the waves, e.g. pulses in the waveguide 15. The transmitter may be a fluidic device (37) (Fig. 2, not shown) which produces pressure wave oscillations by turbulence as air flows through channels (33), (34) and feeds its signal (35) into a transmitting horn (30). The movable element may be a plate (31) having apertures (32) shaped and spaced to vary the signal 35 from full to zero output. A receiver (20) (Fig. 3, not shown) comprises a horn (21) for receiving the signal (35) and passing through a resonator chamber (22) to a turbulence amplifier (23) that receives an input signal (29). The amplifier (23) is connected to a chamber (25) having a diaphragm (26), the chamber (25) being connected to a further turbulence amplifier (24) that produces a control signal (28) by varying an input signal (27). The arrangement provides a frequency selective decoder which passes a selected frequency at the resonant frequency of the diaphragm. The transmitter 16 may produce pulses in predetermined sequences and frequencies or in groups, the receiver discriminating between groups and sequences and frequencies coming from a plurality of transmitters to control a particular element 13, e.g. through an actuator.
