Title: Apparatus for inspecting material
IPC: G06E3/00
Filed: 1958-05-14
Abstract: 886,122. Detecting defects in sheet material. LINDLEY & CO. Inc. May 14, 1958 [June 4, 1957], No. 15426/58. Class 40(3). In apparatus for inspecting longitudinally moving sheet material e.g. knitted fabric, including a photo-electric device for scanning the width of the material, gate means are provided to prevent the registering of a defect, or the stopping of the machine producing the material unless the defect is detected in the same position insuccessive scanning cycles. The scanning unit is mounted on plate 4, Fig. 2 above the moving sheet material and comprises a spot lamp 50 and lens assembly 38, which directs light reflected from the material to a photomultiplier 35, mounted in a housing 2. The housing is oscillated about a shaft 5 by a throw arm and cam arrangement 14, 16 driven by a motor 10. The angle of oscillation of the housing is adjusted so that the whole width of the material is scanned and the motor speed is such that the material is scanned every 2 seconds, and' signal produced in the multiplier is applied via a preamplifier 48 to the input 93B of the circuit illustrated in Fig. 9B. Valve 97 amplifies the signal which is then applied via an amplitude limiter 99 and amplifier 100 to a trigger valve 101 which on firing operates a relay 103 in its anode circuit. This relay on energising applies a signal which cuts off one half of a gate valve 111 and on release after a delay of 1.7 secs. applies a signal to trigger a multivibrator 107 which produces a negative signal of 0.4 secs. duration. This is applied to cut off the other half of the gate valve 111. If a defect signal is produced in one scanning cycle, one half of the gate 111 is cut off during a period 1.7- 2.1 secs. after the production of the signal and if the defect produces a signal during the next scanning cycle both halves of the gate 111 are cut off at the same time, whereby the voltage applied to the grid of thyratron 130 rises and in firing operates a relay 131 which indicates a fault and/or stops the machine.

Title: Improvements in or connected with the mechanical brake systems of winding engines, haulages and other rotating machines
IPC: F16D65/28
Filed: 1946-05-27
Abstract: 633,129. Fluid-pressure-operated brakes. BELL, W. T., and CROMPTON, A. May 27, 1946, No. 15968. [Class 103 (i)] In a brake such as described in Specification 540,921, the accumulator is so constructed and arranged that it serves both to supply the pressure-fluid for the normal operation of the brake and also to apply the brake if the pressurefluid supply fails, a separate brake engine for this latter purpose thus being rendered unnecessary. Normal operation of the brake is effected by a brake engine 4 through a lever 2, pivoted at 3, the piston 5 on its upper face being constantly under the pressure in the accumulator 14 through pipes 6, 15 and on its underface normally to that pressure through the pipe 12, control valve 8 and pipe 15a, so that the brake is released. The brake is applied by the pressure acting on the upper face of the piston by operating the valve 8 to connect the lower chamber of the brake engine to exhaust passage 17. A "follow-up" mechanism 16 for the valve ensures that the lower chamber is connected to exhaust when the operator's lever is in the " brakes on" position to prevent leakage past the piston 5 from releasing the brake. The accumulator comprises a ram 18 to which weights 19 are connected. The weights have a pin-and-slot connection 2a with the lever 2 whereby in the event of failure of the pressure fluid supply the descent of the weights is sufficient to engage them with the lever and thus to apply the brake.

Patent GB-744079-A (GB)
Title: Improvements in or relating to a process for the utilization of acetylene and ethylene mixtures
IPC: C07C29/42
Filed: 1953-06-10
Abstract: A mixture of acetylene and ethylene is circulated in a closed cycle between an acetylene conversion and an ethylene conversion zone, fresh feed make-up is added to the stream circulating to one zone, residual gas from the other zone is recirculated therewith, and the conversion in each zone is controlled so that the residual gas contains acetylene and ethylene in substantially the proportions in the feed make-up.  The conditions in the separate zones are such that selective conversion of acetylene or ethylene to a chemical derivative capable of physical separation from the residual gas occurs.  The feed make-up may be obtained by cracking hydrocarbons such as ethane, and suitably contains equimolar proportions of acetylene and ethylene.  The extent of conversion in each zone is generally about 20-80 per cent.  Selective conversion of ethylene may be by reaction with chlorine and water to form chlorhydrin as in Specification 744,076; by liquid phase chlorination in a chlorhydrocarbon solvent to dichloride as in Specification 744,080, or by catalytic conversion to ethyl chloride with hydrogen chloride as in Specification 744,078. Acetylene may be converted selectively by reacting with excess hydrogen chloride in presence of, for example, mercuric chloride on active carbon at 175-220 DEG  C., to yield vinyl chloride; by reaction with acetic acid and, for example, zinc acetate to give vinyl acetate as in Specification 744,077 or liquid phase reaction using mercuric oxide, boron fluoride and hydrogen fluoride in acetic acid as catalyst; by treating with hydrogen chloride and air in a solution containing copper and ammonium chlorides as in Specification 744,081 to form dichlorethylene which may be used for the manufacture of vinylidene chloride or perchlorethylene by addition of hydrogen chloride or chlorine and demuriation; by contact with hydrogen cyanide in presence of cuprous and alkali metal chlorides or barium oxide on carbon to produce acrylonitrile; by absorbing in a suspension of caustic potash as in Specification 744,082 and treating with an aldehyde or ketone to yield carbinols, e.g. 3-butyn-2-ol or 2-methyl-3-butyn-2-ol, which may react to form vinyl ethers; by treating under pressure with aqueous formaldehyde using copper acetylide on silica as catalyst at about 100-120 DEG  C., mainly butynediol-1,4 being obtained; by reacting with an alcohol containing the sodium alcoholate, at 120-200 DEG  C. and in liquid phase, to form vinyl ethers; and by passing with benzene in vapour phase over a catalyst such as calcined silica, alumina hydrogels to yield styrene. Reaction products are separated as by condensation, scrubbing or distillation.

Title: Improved apparatus for feeding and severing strip material
IPC: G03D15/04
Filed: 1943-01-11
Abstract: 562,751. Feeding webs &c. KODAK, Ltd., PITT, F. H. G., and NAGEL, H. Jan. 11, 1943, No. 15999/41. [Class 100 (i)] [Also in Group XL] Apparatus for feeding strip material, e.g. image bearing photographic paper, in register with a cutting device, comprises main feeding means for feeding the strip a distance slightly less than the minimum length of an image, means for disengaging the feeding means at the end of each feeding movement, and auxiliary feeding means operable thereafter to adjust the strip in relation to the cutter which is rendered operative in response to the passage of a predetermined part of the strip between a light source and a photoelectric cell. The main feeding device comprises a lower feeding roller 2 fixed to a shaft 6 and an upper feeding roller 1 carried by arms 17 fixed to a shaft 18 to which is also secured an arm 22 actuated by a cam 20 on the shaft 6 to raise the roller 1 against the action of a spring 86 at the end of a feed movement of the rollers 1, 2. At the same time a second cam 24 on the shaft 6 acts upon a lever 40 to raise the lower roller 4 of a pair of auxiliary feed rollers 3, 4 into engagement with the upper roller. The shaft 6 is driven from a main shaft 9 through gear-wheels 8, 7 and a clutch which is disconnected at the time of operation of the arm 22 and lever 40, by the engagement of a pin 3a on the clutch cover with a stop 35. The strip is then fed slowly forward by the rollers 3, 4 which may be driven by a belt 108, Fig. 4, from the shaft 9 or bv a hand wheel on the shaft 37 of the roller 4 until one of a series of spaced opaque marks on the strip lies between a light source 97 and a photo-electric cell 100. This causes the energization of a solenoid 102 to turn a lever 46, Fig. 1, about a pivot 47 to cause a dog 49 thereon to engage an arm 54 to turn the stop 35 clear of the pin 34 allowing the clutch to re-engage and again drive the shaft 6 and roller 2. A third cam 25 on the shaft 6 then actuates a lever 62 to operate the cutter 5 to sever a length of strip which then falls on to the spring-supported floor 90 of a receptacle 87. Following this action, the cams 20, 24 operate to move the roller 1 into engagement with the roller 2, and the roller 4 out of engagement with the roller 3. The cam 20 is formed by two side-by-side discs, one of which is angularly adjustable on the other to vary the length of the high part of the cam in accordance with the desired length of feed. The circuit of the solenoid may include a switch 104 actuated by the arm 40 so as to be closed only during the auxiliary feeding movement so that the solenoid is only excited by the passage of one of the spaced opaque marks and not by the passage of other markings on the strip during the main feeding movement.

Title: Improvements in assembling fasteners with washers
IPC: B23P19/08
Filed: 1951-07-05
Abstract: 736,780. Assembling screws and washers. ILLINOIS TOOL WORKS. July 5, 1951 [Aug. 3, 1950], No. 16003/51. Classes 83 (2) and 83 (4). Rolling; bending.-A strip of washers or similar elements is fed from a continuous coil, applied to fasteners such as screw blanks, detents are roll embossed on the screw shanks to maintain the washers in place and the assemblies are broken from the strip, the separated parts being discharged either to a storage container or to feed means for a number of thread-rolling mills. The strip is fed through the machine in a substantially rectilinear path. Screw blanks are fed from a hopper and pass by gravity between inclined rails 18, Fig. 2, and under a cover rail 24 to positive forwarding means in the form of an endless chain 86, the link joints of which engage the spaces between the heads. The strip of attached link-washers 52 is fed from a coil and enters, at 59, slots formed in the sides of the guide rails and sloping upwards to the top surface thereof at 60. Whilst passing through the slots the washers are telescoped on to the screw blanks which are held down on to the rails by spring pads 102 acting on the upper side of the chain. While still under control of the chain the blanks pass between an embossing roll 144, Fig. 9, and a plain roll 116 loosely mounted on the eccentric end of an adjustably fined stub-shaft. Small snugs 154, Fig. 11, are thus raised on the screw shanks and serve to maintain the washers in position close to the heads during subsequent handling. When the threads are rolled these snugs disappear. From the rolls the strip passes by short guide rails to a rotating disc 174 journalled to a bracket at 166 and driven at 170. Each of 'three radial slots 180, Fig. 5, in the disc receive in turn a screw shank whilst the head and washer pass through a central bore 178. The rotation of the disc thus twists off the washer on the contained screw from the adjacent washer held against rotation by the guides. The breaking disc, embossing rolls and feed chain are all geared to a motor-driven shaft, adjustments being provided when needed. Specifications 736,779 and 736,788 are referred to.
