Title: Thread monitoring
IPC: B65H63/00
Filed: 1974-03-08
Abstract: 1461171 Thread detector BRITISH UN ITED SHOE MACHINERY CO Ltd 8 March 1974 [8 March 1973] 10400/74 Heading D1G A method of detecting improper operation of a thread using machine (a sewing machine as disclosed) comprises determining a complete machine operation made up of a number of operating cycles of thread using instrumentalities of the machine, determining a standard amount of thread which would normally be used in such a complete operation, monitoring the actual amount of thread used in such operation and comparing the actual amount with the standard amount and providing a signal, when a difference exists, to indicate improper operation of the machine. The number of operating cycles is determined by a pulse encoder (24, Fig. 1 not shown) attached to the machine arms half and the pulses therefrom fed to Schmitt trigger 50 of the logic circuit. The needle thread (14) is passed round the periphery of a slotted disc (32, Fig. 2 not shown) attached to a braked wheel (28), the slotted periphery of the disc passing between a light (38 Fig. 3 not shown) and a P.E. cell (40) to provide a train of pulses as the thread is used. The logic circuit comprises first and second pulse counters 52, 64 including selector switches 54-58 which are set to the predetermined number of operating cycles and compare the input of the encoder (24) at 62 with the thread monitoring input at 50 and operates gate 60 to stop the machine and illuminate lamp 128 if operation is unsatisfactory. To avoid the device operating during early stitch cycles a device 70 is provided an input at 116 being only provided when the machine is running at its full speed. A further circuit is provided at 130 and includes flip-flop circuits at 136, 138, 140 which, if the normal supply at 132 is disconnected to render the thread monitor inactive, causes the lamp 128 to flash intermittently to indicate the state of the apparatus.

Patent GB-731917-A (GB)
Title: Manufacture of 2-ethyl-hexanal-(1) and 2-ethyl-hexanol-(1)
IPC: C07C47/02
Filed: 1951-05-03
Abstract: 2-Ethyl-hexanal-1 and 2-ethyl-hexanol-1 are obtained by hydrogenation of crotonaldehyde, condensation of the butyraldehyde formed with caustic alkali so as to obtain 2-ethyl-hexenal-1 and subsequent catalytic hydrogenation, the reaction stages being carried out discontinuously or continuously without isolation of the individual organic intermediate products.  2-Ethyl-hexanol-1 may be obtained by first hydrogenating the 2-ethyl-hexenal-1, formed as intermediate product, to 2-ethyl-hexanal-1 and then hydrogenating this until 2-ethyl-hexanol-1 is obtained.  It is particularly advantageous to carry out this last hydrogenation in the gaseous phase after the separation of the aqueous phase and of the catalyst present up to that point.  In the examples: (a) crotonaldehyde is hydrogenated in the presence of calcium carbonate nickel catalyst and kieselguhr and oleyl-methyl-tauride as emulsifying agent; caustic soda is then added with heating and the hydrogen pressure is raised; a mixture containing 2-ethyl-hexanol-1 and some butanol is obtained; (b) crotonaldehyde together with a nickel catalyst, oleyl-sarcoside, as emulsifying agent, and water are treated with hydrogen; caustic soda is then added and the mixture is then hydrogenated again to give 2-ethyl-hexanol-1; if 2-ethyl-hexanal-1 is required the 2nd hydrogenation is carried out at a lower temperature; (c) a mixture of crotonaldehyde, water and calcium carbonate is hydrogenated in the presence of a catalyst consisting of nickel on a carrier in a paste with ethyl-hexanol-1; a small amount of the sodium salt of oleylmethyl-tauride is added as emulsifier; the resulting mixture is treated with caustic soda; the temperature is raised and the mixture is hydrogenated to give a mixture containing ethyl-hexanol-1 and some butanol; (d) crotonaldehyde is hydrogenated in the presence of calcium carbonate and active nickel on a carrier in the absence or otherwise of an indifferent solvent; the resulting mixture consisting mainly of butyraldehyde is run into a vessel in the absence of air and caustic soda p  solution is added; the mixture is then hydrogenated to give a mixture containing ethyl-hexanol-1 and some butanol; (e) crude ethyl-hexanal prepared by the process previously described on hydrogenation gives a mixture containing chiefly ethyl hexanol and some butanol.

Class 123(2) A forced-flow boiler has a cylindrical outer casing 1 the top of which has a recessed portion 3a housing an external combustion chamber 4. Gases from the chamber pass down through a cooling space 5 constituted by a coil 6 of steam generating tubes and rise in an annular space between the coil and the casing to discharge through an outlet 9. The annular space and the gas turning space under the coil 6 locate a series of coiled steam generating tubes 8. Combustion chamber 4 is fitted with liquid or gaseous fuel burners of a type' which ensures that substantially complete combustion occurs within the chamber, the stream of gases flowing through the coil 6 being substanially non-luminous. In this way the generating tubes are not exposed to luminous radiation and possible overheating, a more even distribution of heat through the boiler is obtained. Specification 492,709 is referred to.

Apparatus for viewing two objects having identical portions and portions which differ in which the images thereof are combined to render visible only those portions which differ, i.e. utilizing the subtraction process, comprises a first television camera 3 providing to a first television monitor 10 a video signal the polarity of which may selectively be inverted, a second television camera 11 containing a storage pick-up tube 12 positioned to view the screen of monitor 10, and a second television monitor 13 fed with the video signal from camera 11. In operation, two radiographic negatives 2 and 6 having identical elements 7 and a different element 8 are mounted in frames 1 and 4 in an apparatus 9 including a light source. Optical superposition of the contours of the negatives is obtained by superposition of the two frames, frame 4 being slidably mounted and the position of negative 6 being adjustable. Frame 4 is then moved away and negative 2 is viewed by camera 3 and the resulting video signal is displayed on monitor 10 in its normal polarity. Camera 11 records this image and transmits it to monitor 13, camera 3 being shut off when the contrast of the image provided by the storage tube 12 on monitor 13 attains a predetermined value, e.g. half of the maximum possible contrast. Frame 2 is then removed and frame 4 slid into the field of view of camera 3. The output signal of camera 3 corresponding to negative 6 is inverted and the camera 3 is kept operative until the instant at which the storage tube 12 produces on monitor 13 a positive in which all contrast has disappeared in parts common to the two negatives. At this moment image 14 is obtained representing the result of the subtraction process.
