Title: Improvements in devices for removing rigid sheets from a conveyor grid
Inventor: KERSUAL JEAN
IPC: B65G47/91
Filed: 1953-06-10
Abstract: 744,382. Sheet-delivery apparatus. ETABLISSEMENTS P. CAPDEVIELLE. June 10, 1953, No. 15960/53. Class 100 (1).  A device for removing rigid sheets from a conveyer grid comprising an extracting member carrying a gripper is characterized in that the operation of the gripper and the movements of the extracting member are controlled by the arrival of each sheet in a definite withdrawal position whereby damage or deterioration of irregularly arriving sheets is avoided. As shown the extracting member consists of a vertical piston 3 and a horizontal piston 4 connected by a rod 5, the piston 3 sliding in a cylinder 6 which is pivotally mounted on a shaft 7, and the piston 4 sliding in a cylinder 13. Inside the piston 4 a fixed piston 35 slides in a bore 34, the piston 35 being fixed to a rod 36. A slide valve 20 is provided and is operated by a pin 18 on the piston 4 for controlling the suction and air admission to the cylinder 4. In the position shown the suction port 25 is closed and the air admission port 26 opens so that air passes through openings 23, 22 and enters a flexible tube 27. The piston 3 being then at the top of its stroke air passes into a central bore 12 through a passage 28 and the sucker 11 releases an extracted sheet. The piston 3 is pushed down by a spring 8 and air then passes through a passage 30 and a tube 32 to the cylinder 13. The piston 4 is acted on by the spring 15 and returns to its former position, its travel being limited by a guide 14. The pin 18 then acts on the slide valve 20, shutting off the air admission port 26 and opening the suction port 25. The suction action is transmitted through the tube 27 and causes the piston 3 to be raised. When a sheet arrives and covers the sucker 11 the piston 3 completes its travel to raise the sheet and the reduced pressure in the bore 12 of the piston 3 is transmitted through the tube 32 to the cylinder 13 so as to return the piston 14. By means of a passage 39 the suction is transmitted over the whole of the surface of the piston 4 during the initial movement thereof. In a modification (Fig. 5, not shown) the vertical piston is directly connected to the horizontal piston and slides with a horizontal reciprocating motion in a guide rigidly connected to the cylinder of the horizontal piston.

Title: Improvements in and relating to automatic feed weighing apparatus
IPC: G01G13/02
Filed: 1928-06-01
Abstract: 318,281. Davis, F. W. June 1, 1928. Automatic-feed weighers.-Apparatus for delivering a predetermined weight of liquid, granular or pulverized material at predetermined intervals of time is characterized in that the supply of material to the weighing beam is cut off on the recoil of the weighing beam after discharge of the material. In one form of the invention a screw conveyer delivers granular material from a hopper R to a compartmented drum N carried on a scale beam P and discharging and re-setting itself in known manner. The screw conveyer is rotated, to feed the material, by means of a ratchet wheel C, a pawl B, and a constantly-reciprocating rod A. When the compartmented drum has received its' charge the scale beam tilts, the drum discharges-and a pin E on the beam engages and draws down a hook H connected to the pawl B by a weighted lever E and link J. The pawl is raised from the ratchet wheel C and the conveyer is arrested thus cutting off the feed. After a predetermined interval of time, a constantly-rotating timing cam M displaces the hook H from engagement with the scale beam and allows the lever E to lower the pawl B into engagement with the ratchet wheel and commence another weighing operation. The timing cam M mav be mounted loosely on the ratchet shaft D and may be operated by a second ratchet wheel and crank shaft. When the material is a liquid the ratchet wheel C and its pawl drive are dispensed with, and the weighted lever E operatesa stop cock. When several machines are used in conjunction as proportioning machines, the timing cams of the machines are coupled together so as to rotate at the same speed or relative speeds. By varying the speed at which the coupled cams are driven the rate of discharge of the total weight may be varied without altering the relative proportions.

Abstract: 355,710. Yarn - - clearing apparatus. CROAD, A. K., 70, Chancery Lane, London. -(Eclipse Textile Devices, Inc. ; Oakwood Avenue, Elmira, New York, U.S.A.) May 24, 1930, No. 16059. [Class 120 (ii).] Yarn-clearing apparatus of the type described in Specifications 195,599 and 202,619, [both in Class 120 (ii), Spinning, twisting, &c.], is characterized in that the force urging one clearing member against the other is much less than the weight of the clearing member, and is so slight as not to exert tearing pressure on the yarn. This permits one or both of the members to vibrate in a direction perpendicular to the travel of the yarn. A supporting bar 10 has a bracket 11 which is clamped to a bar B by a screw 12. The side surface 13 of the bar 10 is slightly inclined to the vertical and carries the fixed side member 20 of the yarn clearer. Studs 17 project from the fixed member 20 and engage loosely in holes in the movable member 30 of the clearer. Both of the members 20, 30 carry blades 21, 31 having opposed scraping edges 23, 33 shaped to provide the minimum clearance at the line of travel of the yarn. One set of the scraping edges has small aligned notches at this point of miminum clearance. Screws 50 are threaded in tapped holes in the studs 17 to adjust the distance between the scraping edges and stops 51 formed at the ends of brackets 52 provide a limit to the adjustment. The movable member may carry no blades but be provided with a smooth surface which bears against the blades on the fixed member ; or the frame may be set horizontally and the movable member be urged towards the fixed member by a light spring; or both members may be movable and be urged towards one another by two light springs.

The pulses 91 are delayed by 120 and 240 degrees at 18 and 19 and used to gate 20, 22 the output of subtractor 15 to provide R and B signals respectively through filters 21, 23. The R and B signals are added 24, and gated 25 by pulses # 1  and the output P 1  is added at 27 to the output P 2  of a gate 26 supplied with the R signal and controlled by pulses # 3 . The signal P 1 +P 2  is subtracted at 14 from the signal S(t) to provide a G signal of a bandwidth substantially equal to that provided by the scanner 12. The delay 16 may be substantially equal to a horizontal scan period, or equal to T/3 where 1/T is the frequency of the subcarrier, depending on whether vertical or horizontal correlation of the image signal is relied upon. To reduce R-B crosstalk the bandwidths of the R and B signals are limited by using a dichroic beam splitter to separate the R and B optical image components and defocusing the R and B images at the scanner. A monochromatic film may replace the scanner 12, this being scanned later by a pickup tube or flying spot scanner.

Title: Improvements in the manufacture of hydroxy amino compounds
IPC: C07C215/76
Filed: 1937-06-10
Abstract: An aromatic or heterocyclic nitro compound is converted into an aminohydroxy compound by reducing the nitro compound, in the presence of water, to the corresponding hydroxylamine derivative, and heating the latter, without isolation from the solution, with a non-oxidizing acid, whereby the hydroxyl group of the hydroxylamine residue is transferred to the nucleus; the mixture is then cooled and neutralized to recover the aminohydroxy compound.  The reduction of the nitro compound may be effected with zinc dust, sodium or ammonium hydrosulphide, aluminium or hydrogen, and may be catalysed by addition of a water-soluble salt of ammonia or of an amine or of an alkaline earth metal with an acid which forms a water-soluble zinc salt; specified catalysts are ammonium chloride, sulphate and acetate, methylamine hydrochloride, and calcium chloride.  In an example, an emulsion of nitrobenzene in aqueous ammonium chloride is treated with zinc dust, and afterwards filtered to remove zinc hydroxide; the filtrate, containing phenylhydroxylamine, is acidified with sulphuric acid, heated to 80-100 DEG  C., cooled, and made slightly alkaline by addition of ammonia, whereby a precipitate of p-aminophenol is obtained.  Other nitro compounds which may be treated are bromonitrobenzenes, nitrotoluenes, nitroxylenes, nitronaphthalenes, nitroanthracenes, nitroanthraquinones, nitropyridines, nitroquinolines and nitrothiophenes.  Specification 221,227, [Class 2 (iii)], is referred to.
