Abstract: 1,268,573. Conveyer system for paper wrapping machines; endless conveyers. A. SERAGNOLI, E. SERAGNOLI, and M. T. CHIANTORE, [trading as G.D. S.A.S. DI ENZO SERAGNOLI E ARIOSTO SERAGNOLI]. 20 Nov., 1969 [28 Nov., 1968], No. 56870/69. Headings B8A and B8C. In a device for feeding chocolates 7 to the wrapping wheel 9 of a high speed paper wrapping machine 8 of the kind wherein endless conveyer belts 4, 5, are both driven by a common motor 30 which also drives the machine and so that the conveyer 5 travels faster than the conveyer 8, the chocolates 7 are transported between guide members 17, 17 to a fixed stop 6 where they are transferred, singly, by a pusher 8, to the wrapping wheel 9, the speed of the motor 30 being increased when the chocolates pile up behind the bar 6 to extend, rearwardly therefrom past a first 18, and up to, or beyond, a second chocolate, sensing mechanism 19. When there is no supply of chocolates to the low-speed conveyer 4 neither of the light beams 22, 23, Fig. 4, of the sensors 18, 19 which control respectively switches TL3, TL4, are interrupted so that neither of the switches TL2, TL1, which are controlled respectively by the switches TL3, TL4, are actuated to energize the motor 30 and move the conveyers 4, 5. When the chocolates build up behind the stop 6 sufficiently to interrupt the light beam 22 both pairs of contacts of the switch TL3 close so that power is supplied to the switch TL2 which, closes its contacts 1-3, 5-6 and opens contacts 4, 8 to supply energy to the motor 30 so that it runs at its normal speed. Build up of chocolates sufficient to break the light beam 23 of the sensor 19 actuates the switch TL4 which cuts off the supply to the switch TL2 which removes the supply from the motor 30 and closes the contacts 4, 8 to provide a circuit to the switch TL1 which closes contacts 1-3, 5-7 to supply alternative power to the motor 30 so that it rotates at its higher speed, and opens contacts 4, 8 in the circuit to the switch TL2. As the build-up behind the stop is reduced the motor 30 is changed to its normal speed as the light beam 23 ceases to be interrupted, the motor 30 switching off when the light beam 22 is also not broken. The circuits to the switches TL3-TL4 each includes an amplifier 26 or 27, a rectifier R 1  or R 2 , and a condenser C 1  or C 2  the time constant of which is chosen to ensure that the associated switch TL3 or TL4 ignores the passage of a single chocolate through the beam 22 or 23.

Abstract: 1450216 Automatic textile dyeing SANDOZ Ltd 11 Dec 1973 [15 Dec 1972 13 April 1973] 57385/73 Heading D1L In the exhaust dyeing of textiles by the relative movement of the textile and dye liquor, at least one of the parameters that control dye absorption onto the textile e.g. pH or temp., are regulated to maintain the rate (D) of dye bath exhaustion as a function of the number of cycles dye liquor or textile, below a value above which uneven dyeing is obtained. The value of D may be monitored continuously by colourimetrically measuring the dye concentration as a function of dye liquor circulation rate. Alternatively the value of D may be monitored indirectly from predetermined measured variations of the control parameters with circulation rate. In the former method, the textile S to be dyed is immersed in the dye bath DB is dyed by the circulation of dye liquor DL by means of reversible direction pump P. The flow rate of the dye liquor and the dye liquor concn. are measured at F and C respectively. The outputs from these monitors are passed to a data processing unit G, H and I which compares the measured value of D with the required value set by M. Any regulation of the control parameters i.e. pH or temp. at PH and T respectively, is controlled by a predetermined sequence fed in on e.g. a punch card D. The maximum value of D may be 0.2-20% of the initial dye concn. of the bath. The process may be applied to cheese and cone, beam, jig, winch back, paddle, pack, jet, rotary or hank dyeing.

Abstract: 1324809 Purifying gas streams CIT COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS 9 Dec 1970 [9 Dec 1969] 58522/70 Heading B1R [Also in Division C1] Exhaust gas containing particles and oxides of sulphur and nitrogen is passed from burner 1 to and through column 2 cocurrent with wash liquor introduced at 3, and thence to and through column 6 countercurrent with wash liquor at 35-45‹C introduced at 7, before being vented to the atmosphere. The packing material 4 in columns 2, 6 is suitably chips of polyamide. The wash liquor used in both columns is supplied by pumps 14, 15 from bath 10 in which is contained finely divided iron or ferrous or ferric carbonate or oxide. In the case of gas containing oxides of sulphur, ferrous sulphate forms in the wash liquor and is returned from bath 9 to bath 10 while entrained particles are run off from bath 9. Part of the ferrous sulphate which is formed is eliminated in bath 12 by blowing air and possibly also a catalyst into the liquor at 16; ferric sulphate collects at 17 and is run off while solution is returned by pump 13 to bath 12. The ferric sulphate may thereafter be hydrolysed to sulphuric acid and ferric oxide, which latter may be returned to bath 10. Alternatively, excess ferrous sulphate in the liquor in bath 10 may be removed by cooling the liquor to below 30‹C and removing the crystallised salt which forms. If preferred, the liquor supplied to columns 2, 6 may be taken from bath 12 instead of bath 10, in which case the line returning liquor from bath 12 to bath 10 is unnecessary. Oxides ofnitrogen are removed in an analogous manner.

Each sense line of a word organized store, Fig. 1 (not shown), is connected at IN to a non-inverting amplifier 3-1, Fig. 2, and when a "1" is read the line applies a negative pulse to this input, the amplifier output also producing a pulse when the input threshold T is exceeded, Fig. 3. The amplifier output pulse back biases diode D1, and the strobe pulse is applied to back bias diode D2. This drives a latch formed by transistors Q 2  and Q 1  into a conducting state, but because the strobe pulse also back biases diode D7, the output transistors Q 3 , Q 4  and Q 5  are isolated from the latch. On termination of the strobe pulse the isolation ceases and normal, inverted, and indicator lamp drive signals A1, A1 and IND 1 are given by Q 3 , Q 4  and Q 5 . The circuit may be reset to its initial state with the latch non-conducting by applying a positive pulse on the Clear line, Fig. 2.

An article of a glass containing replaceable Na and/or K ions may be chemically tempered by heating to at least its annealing point, exposing to vapours of at least one lithium compound which will volatilize without decomposition, so as to exchange Na and/or K ions for Li, terminating the exposure to Li-compound vapour, and cooling to a temperature below the annealing point and at least below 800 F. in the substantial absence of the vapour. Examples of glasses used are given. The lithium compound may be LiF, LiCl, LiBr, LiI, LiNH 2  (in the absence of water vapour) and/or Li 2 SO 4 . Preferably the exposure is for 1-60 minutes at temperatures corresponding to glass viscosities of 10<SP>10.0</SP>-10<SP>12.6</SP> poises. For soda-lime glasses this is preferably 25-150 F. above the annealing point. The exposure may be carried out in a tube 3 heated by coils 4, the glass articles, in this case rods 1, being supported on refractory supports 2. The tube is heated to, e.g., 1100 F., and then a boat 8 containing Li compound 9 introduced to carry out the exposure. Alternatively the Li compound may be placed in the tube with the articles and heated simultaneously, exposure of the article to the compound's vapour being substantially prevented by a circulating atmosphere. Sheets, fibres or glass bottles or containers may also be treated by the process of the invention. Sub-atmospheric pressure may be employed in the treatment chamber. In an example (Example 5) glass rods were treated with LiNH 2  while dry N 3  was used to sweep out any water vapour, the treated rods having a brown coloration.
