Title: Digital Regulating Installations
Inventor: UHLIG JOACHIM
IPC: H03K21/02
Filed: 1968-08-20
Abstract: 1,194,087. Programmed control. STARKSTROM-ANLAGENBAU KARL-MARX-STADT VEB. Aug.20, 1968, No.39810/68. Heading G3N. A circuit arrangement for the continuous comparison of two pulse series introduced with plus or minus sign, especially desired value and actual value pulses of a continuously acting digital regulating installations is connected so that as shown, input pulses A, B are fed to the direct inputs of stores A1, B1, and through negators to the inverse inputs of the stores, and their counting sense (positive or negative) fed at 1, 2, respectively to a sign store V3. The inputs of stores A2, B2, are connected to the outputs of stores A1, B1, and the negated outputs of stores A2, B2, and the direct outputs of stores A1, B1, are fed to AND-gates A3, B3. The outputs of gates A3, B3 are fed, in parallel, to a sign evaluation circuit V2, a comparison circuit V1, an AND-gate 4 and an OR-gate 6. The output of the AND-gate 4 is fed directly, and through a negator 5 to a store 51, the direct output of which is fed to the OR-gate 6. The outputs of the OR-gate 6 and the comparison circuit V1 are fed to AND-gates 7, 8, enabled by a 'similar' signal a and a 'different' signal b, respectively, from the sign evaluation circuit V2, to provide outputs through an OR-gate 9 to a pulsegate 10 emitting a pulse Z1 to a backwards-forwards counter, not shown, the count direction of which is determined by outputs C, D, of the sign evaluation circuit. Stores A1, A2, B1, B2, S1, circuits V3, V2, and the pulse-gate 10 are set by clockpulses on a line 3. For different senses of simultaneous input pulses no signal is fed from the comparison circuit to gate 7, and gate 8 is enabled by signal b from the sign evaluation circuit, so that, through the store S1 a pulse is developed by pulse-gate 10 on the record clock pulse in a four pulse sequence. For similar sense input pulses, AND-gate 7 is enabled and the result of the comparison circuit V1 is fed to the pulse-gate 10 when a pulse is present only on A or B. The count direction is determined by the sign evaluation circuit V2.

Title: Preparation of polyesters
IPC: C08G63/78
Filed: 1961-11-10
Abstract: 944,069. Polyesters. PITTSBURGH PLATE GLASS CO. Nov. 10, 1961 [Nov. 14, 1960], No. 40298/61. Heading C3R. Polyesters are made by heating a mixture of a polyol and a dicarboxylic acid or anhydride thereof in the substantial absence of a solvent, passing inert gas through the reaction mixture to remove water as well as vapour of the polyol, passing the evolved gaseous components through a fractionating column maintained at a temperature above the boiling point of water and below the boiling point of the polyol, passing the vapour from the column to a partial condensation zone wherein they are cooled to a temperature slightly above the boiling point of water to condense out vapour of the polyol, returning liquid polyol to the top of the column and allowing the mixture of inert gas and water vapour to escape from the partial condensation zone. The reaction mixture is charged to a reactor 10 provided with a heating coil 11, on agitator 16 and an inert gas inlet 18. Vapours from the reactor pass through a fractionation column 23 generally maintained at 240‹-430‹F. and vapours from the column pass to a condenser 28 maintained at a temperature from above the boiling point of water to 240 ‹F. by circulation of a suitable heating or cooling medium. Polyol vapours condensed in condenser 28 return to the column 23 whilst water vapour and inert gas are discharged through pipe 33. At the beginning of the polyesterification (especially if a dicarboxylic anhydride is used as a reactant) a reduced inert gas flow is maintained, then, when substantial quantities of water are evolved, the rate of flow is increased. When nearly all of the water has been evolved, the rate of flow is still further increased and the gas switched from the column to the atmosphere by means of valves 22 and 36. Examples describe the manufacture of polyester by reacting (1) Maleic anhydride, phthalic anhydride and propylene glycol; (2) Maleic anhydride and diethylene glycol followed by the addition of phthalic anhydride and propylene glycol and further reaction; (3) Maleic anhydride, isophthalic acid and propylene glycol; (4) Maleic anhydride, phthalic anhydride, propylene glycol and diethylene glycol. Other polyesrter forming compounds mentioned are chlorendic, tetrachlorophthalic, tetrahydrophthalic, adipic, succinic, terephthalic and fumaric acids or anhydrides; and ethylene-, triethylene-, dipropylene-, tripropylene- and butylene-glycols and glycerine.

Title: Fuse for nongyratory missiles
IPC: F42C15/24
Filed: 1972-09-01
Abstract: 1346703 Projectile fuzes MEFINASA 1 Sept 1972 [10 Sept 1971] 40623/72 Heading F3A A fuze which can be manually set for direct or delayed action on impact comprises, a delayaction striker 27 and a direct action striker 7 which can be prevented from reaching a detonator 12 by means of a manually rotatable blocking device 8. A carrier 25 for the detonator 12 is held against forward movement under the action of a spring 19 by a number of elastic fingers 21 extending from a ring 20. A displaceable sleeve 22 holds the fingers in position. Similar fingers 32, extending from a ring 31, are retained in engagement with the striker 27 by a displaceable sleeve 30. The tip of the striker 27 is engaged in a recess in a shutter 38. A pin 40 locks the shutter against the action of a spring. A member 17 contains passages which lead to a primer 18 but which, in the unarmed condition of the fuze, are out of alignment with a detonator 37 and a flash passage 16. When a projectile fitted with the fuze is fired, the sleeve 22 and ring 20 set back. The fingers 21 thereby release the carrier 25 and the detonator 12 is moved within striking distance of the striker 7. A member 34 also sets back and a spring 29 becomes permanently loaded as an elastic ring 35 engages behind a shoulder 36. The forward movement of carrier 25 releases a stud 41 and enables member 17 to rotate into a detonation transmitting position. On impact with a target, an arcuate portion 9 of the member 8 prevents the striker 7 penetrating the detonator 12 if the fuze is set for delay action. The sleeve 30, however, moves forwards to release the fingers 32. As soon as this occurs the ring 31 and striker 27 also move forwards. The tip of the striker is thus withdrawn from the shutter 38 which then rotates to expose the detonator 37, the pin 40 being no longer retained by the carrier 25. The spring 29 drives the released striker into the detonator once the acceleration produced by the arresting of the projectile is reduced to zero.

Title: A method of treating textile fabrics
IPC: D06M13/53
Filed: 1964-10-07
Abstract: Fabric, e.g. of cotton, is impregnated by padding with an aqueous solution containing a curable treating agent, partially dried to a moisture content of 15 - 35% by weight, the treating agent is cured while the fabric is held at this moisture content and the fabric is then dried.  The fabric may be rendered crease-resistant or waterproof by the process.  After impregnation the fabric may be adjusted to a moisture content of 15 -35% by weight either by high pressure squeezing followed by slightly drying or by normal squeezing followed by carefully controlled extensive drying.  The curing may be effected by a long-term treatment of the fabric in an open boiler, by heating the fabric to 50 DEG  - 100 DEG C, winding it on a roll and placing it in a closed chamber for up to 5 hours or by passing the fabric to a through-going chamber, e.g. a ring winding chamber, at 80 DEG  - 100 DEG C in dense steam conditions for 3 - 10 minutes, the curing time being reduced to one minute or less if the fabric is treated by condensation-free heating means, e.g. an infra-red heating zone, to a temperature of 100 DEG C before passing it to a through-going high-pressure steam chamber where curing is effected at a temperature above 120 DEG C.  Cotton fabric may be rendered crease-resistant by treatment with a urea-formaldehyde resin precondensate.

Title: Shoe lasting
IPC: A43D21/12
Filed: 1971-09-02
Abstract: 1389016 Boots &c C I C RALPHS Ltd 29 Aug 1972 [2 Sept 1971] 41100/71 Heading A3B A method of lasting the forepart of a shoe includes the steps of arranging an upper loosely disposed about a last with a lasting margin projecting therefrom, clamping the upper against the periphery of the sole part of the last, subjecting the upper to a mechanical stressing to bring it to the required shape, and then, while the upper is still clamped, turning over the lasting margin and securing it to an insole. As described the method is performed on a last having a forepart filler portion 42 which is movable from a retracted position to the position shown in Fig. 6 to effect the mechanical stressing of the upper. The sole plate 36, waist portion 38 and heel portion 40 are mounted on a fixed column in a lasting machine and the forepart filler portion 42 is mounted on a column 52 which can be moved lengthwise by an actuator 60 to effect dressing of the upper. The heel portion 40 is removably mounted on the column 48 to facilitate placing and removal of the upper from the last. The machine operates as follows:-the upper 44 (which has previously been heated in oven 34) and insole 46 are assembled on the last with the forepart filler 42 in its retracted position and an insole clamp 170, 172 is moved to operative position by actuator 166. The pincer assembly 22 is then moved to operative position and the toe end of the upper is gripped by pincer 131 which is then raised. Side pincers 132 then swing inwardly and grip the upper and a clamping band 118 moves upwardly and forwardly to its operative position. During this upward movement the clamping band 118 engages the side pincers 132 and raises them to tension the upper. The clamping band 118 is then operated to clamp the upper against the periphery of the sole plate 36 of the last and the pincers 131, 132 then release the upper and move to their inoperative position. The forepart filler portion 42 of the last is then moved by actuator 60 to stress the upper. The upper is then cooled by jets of air from nozzles 180. A wiper head 16 then moves to its operative position, the wipers (not shown) are operated and bedding pressure is exerted by actuator 90. The wiper head 16, insole clamps 170, 172 and clamping band 118 then move back to their inoperative positions. A sole unit may then be secured to the lasted upper. A heater 158 is lowered to the position shown dotted in Fig. 4 to activate adhesive applied to a sole unit positioned in pad box 138. The heater 158 is raised by actuator 162 and the pad box 138 carrying the sole unit is moved to operative position by actuator 142. Bedding pressure is then applied by actuator 152.

Abstract: 1,152,927. Coke binder pitch. ESSO RESEARCH & ENG. CO. 15 Sept., 1967, No. 42103/67. Heading C5E. Pitch binder for electrodes is made from petroleum tar fractions or coal tar fractions by dealkylating the feedstock in a fluidized coke bed at 1300‹ to 1600‹ F under a pressure of 0 to 100 p.s.i.g. for 0À1 to 10 seconds, recovering the dealkylated vapour and converting it at temperatures of 650‹ to 800‹ F. for 1 to 6 hours to a condensed aromatic fraction, and fractionating the converted material to recover the aromatic fraction as bottoms. In a modification of the above method, an intermediate distillate (B.R. 400‹ to 825‹ F.) is recovered from the fractionating step and oxidized at 200‹ to 650‹ F. for 1 to 24 hours to produce a pitch. The final product in both cases boils above 800‹ F., has a Conradson carbon number of at least 50 and a softening point in the range 180‹ to 290‹ F. In an illustrated embodiment, the dealkylated vapour, after solids removal, is quenched to 700‹ to 900‹ F. by injecting an oil, e.g. a midrange boiling fraction from the fractionator, into the vapour, and conversion is carried out in a condenser-soaker where C 4  and lighter gases are flashed off. Feed-stocks which may be utilized include heavy virgin residuals; the bottoms from the distillation of catalytically cracked gas oils, the bottoms from steam cracking light or heavy cycle oils at 1200‹ to 1500‹ F., coal tar pitch, coal tar oils of B.R. 500‹ to 850‹ F. and shale oil boiling above 650‹ F. A preferred feed-stock is produced by catalytically cracking a mid-boiling petroleum fraction and steam cracking the product at 1200‹ to 1500‹ F., and. recovering the tar bottoms.. Comparative examples are described.
