Title: Improvements in or relating to preparing fried potato products
IPC: A23L19/18
Filed: 1961-04-04
Abstract: A fried potato product is produced from raw white potatoes by preparing an extrudable, moist mixture consisting essentially of potato cells which are intact, potato cells which have been ruptured and the starch contained therein, and a thermal gelling binder, effecting solvation between the binder and the mixture by maintaining the binder and the mixture at a temperature not exceeding 90 DEG F., shaping the resultant product and deep fat or French frying the shaped product. The mixture may include dehydrated potato particles which have been rehydrated in the presence of the binder. A prepared mixture adapted to be stored dry and subsequently deep-fat fried, consists essentially of 5-35% crushed dehydrated potatoes, 95-65% ground potato flakes and 1-8%, based on the total weight of potato solids, of an edible thermal p gelling binder distributed throughout the mixture, between 20% and 30% of the potato solids thus having ruptured cells the ruptured cell content may be obtained by mixing, by extended cooking, by employing small cut up pieces of potato such as undersized pieces normally removed from standard French fried production or by adding dry ungelatinised potato starch. The mixture may include also seasoning (salt), cheese or onion flavourings, added starch (preferably potato starch), monoglycerides and non-fat dry milk solids. If desired, the shaped product may be partially fried, subjected to cold storage and again fried or baked when required for use. Thermal gelling binders: cellulose ethers, including methyl cellulose ethers, and the propylene glycol ether of hydroxymethyl cellulose and pectinates, caseinates, alginates and wheat gluten when a dehydrated mix is employed. Potato products: French fried potatoes, potato patties, croquettes, chips, shoe-strings and other crisp snack items, and special forms of product such as round or elongated French fried potatoes and croquettes shaped as a baked potato. Examples directed to the production of the fried potato products are given. Specification 985,809 is referred to.

Title: New steroid compounds and processes for their preparation
IPC: C07J75/00
Filed: 1961-08-09
Abstract: The invention comprises pregn-4-en-3-one derivatives having the general formula: <FORM:0970586/C1/1> in which R2 represents the grouping =H(OY), R3 represents one of the groupings =H(CH2OY), =OH(CH2OY) or =(CH2OY)2, (where Y in the aforesaid groupings indicates an hydrogen atom or an acyl radical derived either from an organic carboxylic acid having 1-18 carbon atoms or from a mineral acid), and R4 represents the groups =H(OH) or the oxygen atom =O and their corresponding 3-ketal derivatives when R4 is the oxygen atom and R3 is H(CH2OY) or (CH2OY)2, a process for the production of 20, 21-dihydroxy -20- hydroxymethylene-pregn-4-ene-3,11-dione, in which the 21-hydroxy group is blocked by esterification prior to treatment thereof with an hydroxylating agent e.g. osmium tetroxide so as to yield upon saponification the desired 20,20-dihydroxy-20-hydroxymethylene-pregn-4-ene-3,11-dione and a process for the production of a 3-ketal of 20-hydroxymethylene-21-hydroxy-pregn-4-ene-3,11-dione and a 3-ketal of 20-bis-hydroxymethylene-21-hydroxy-pregn-4-ene-3,11-dione in which a 3-ketal of pregn-4-ene-3,11,21-trione is subjected to a Tollens condensation reaction with formaldehyde so as to yield a mixture of the desired 3-ketals. The 21-hydroxy-20-methylene-pregn-4-ene-3, 11 - dione starting material is formed by reacting a 3-ketal of pregn-4-ene-3,11,21-trione with formaldehyde to yield the 3-ketal of 20-methylene-pregn-4-ene-3,11,20-trione which is reduced e.g. with sodium borohydride to obtain the 3-ketal of 21-hydroxy-20-methylene-pregn-4-ene-3,11-dione, which is deketalized to obtain the desired 21-hydroxy-20-methylene-pregn-4-ene-3,11-dione. The 3-ketal of pregn-4-ene-3,11,21-trione starting material is in turn obtained by oxidation of the 3-ketal of 21-hydroxy-trans-pregna - 4, 17(20) - diene - 3, 11-dione so as to yield the corresponding 3-ketal of trans-pregna-4,17(20)-diene-3,11,21-trione which is then reduced. Any of the 3,11b -dihydroxy compounds obtained in the above processes may be oxidized to the corresponding 3-keto-11b -hydroxy compound e.g. with manganese dioxide. Specifications 970,587 and 970,588 are referred to.

Patent ES-316512-A1 (ES)
Title: Improvements in and relating to the production of metallic webbing
IPC: B21F27/12
Filed: 1965-08-14
Abstract: A method of continuously producing metallic webbing, from a continuous length of chain and from wire staples comprises stapling together selected individual pairs of links of the chain, each pair consisting of two links spaced apart along the length of the chain. Wire 1 is fed by rollers 3, moved apart once a revolution by cam means 4, and a length is cut therefrom when stationary by a knife 5 on a slide 6. The cut length is formed into a U-staple by pivoted bars 7 which, as the slide 6 moves down, bend the wire over a support 9, engagement of the bar 7 with a tapered guide 8 causing them to move, in addition, towards one another. The legs of the then formed staple extend through links 10 spaced apart along the length of a chain but brought side-by-side by passage of the chain helically over pulleys 14 on a pair of intermittently rotating shafts. The ends of the staple are bent over the support 9 to connect the links 10 by members 11 on a second slide, a member 13 completely closing the staple. The length of the webbing formed is determined by stopping the feed of wire, and thus staples, at intervals by ratchet means 16 which separates the feed rolls 3, so that a line of unconnected links extends across the width of the webbing. The width of the webbing formed is determined by stopping the wire feed for successive staples, by ratchet means 17, for a length of time corresponding to the passage of two webs in side-byside alignment.

Title: Automatic firearm with breech mechanism unlocked by the recoiling barrel
IPC: F41A5/32
Filed: 1968-10-02
Abstract: In an automatic firearm in which the breech is unlocked by a member actuated by a recoiling part 6 of the firearm, a primary cylinder 33 in which is disposed a primary piston 34 connected mechanically, 34b, 28, to the recoiling part, communicates with a secondary cylinder 35 in which is disposed a secondary piston 36 actuating the member 23, 22 operating the breech block 2, the cylinders being filled with liquid between the pistons, the effective cross-section of the primary piston being greater than that of the secondary piston to impose on the latter a speed greater than that of the recoiling part, a communicating passage 44 being provided between the two sides of the primary piston, the passage being capable of being blocked off at an adjustable point of the stroke of that piston to permit adjustment of the point at which the speed augmentation, and hence firing rate, occurs. The cylinder 33 is provided with two sets of helical passages 44 and 45 (Figs. 2a and 5) while the primary piston 34 has helical lands 46. The passage group 44 is initially open for a rearward movement "a" of the piston 34 and is subsequently closed for a further movement of "b" + "c", the passage group 45 then re-establishing the communication across the piston. The primary piston is rotatable by a hand lever 49 to vary the distance "a", the effective stroke "b" + "c" remaining constant. Action.-On firing, the barrel 7 and part 6 recoils, driving piston rearwards. Fluid pressure between the pistons moves the smaller piston 36 rearwards at a higher speed carrying with it the unlocking push-piece 23, its projection 22 abutting face 21a of the slidable casing 9. As the latter moves rearward skews 19 engage rollers on a pin 11 carried by breech block 2 to rotate the latter from engagement with locking lugs 5 before opening the breech. After cartridge ejection a spring and a damper device return the breech mechanism, an inclined surface 26 then actuating member 27 to disengage leaf-spring 24 and allow casing 9 to move forward relatively to the block 2 to rotate and lock the latter. The primary piston is provided with passages 54 co-operating with a disc 55 to act as a oneway valve allowing fluid to return to the righthand side of the piston when the weapon recuperates.

Title: High-crimp, high-strength rayon filaments and staple fibers and process for making same
IPC: D01F2/06
Filed: 1969-04-08
Abstract: High-tenacity rayon filaments and staple fibers having an exceptionally high number of crimps per inch are produced by spinning a viscose spinning solution into a coagulating-type spin bath to obtain coagulated, incompletely regenerated viscose filaments, the coagulated viscose filaments withdrawn from the spin bath being stretched from about 120 to 280 percent in length while the filaments are still substantially soluble in dilute alkali solution, the filaments being treated with a hot acid bath while being stretched. The tension of the filaments is then relaxed about 20-60 percent while the filaments are less than 50 percent regenerated, and the thus relaxed partially regenerated filaments are treated with an alkaline solution having a pH of from about 7.5 to 10. Regeneration of the filaments, or of staple fibers prepared therefrom, is then completed without additional stretching, followed by conventional desulfurization and washing of the highly crimped filament or staple fiber product.

Title: A device for testing the dimensional accuratcy of axially symmetrical parts
IPC: B07C5/06
Filed: 1969-10-06
Abstract: Apparatus for testing the accuracy of certain dimensions of plastics parts 1 such as the spring sockets and nozzles used in spraying bottles comprises a turn-table 15 having associated therewith automatic testing stations for testing the dimensions of the parts, an automatic feed to deliver the parts to the turn-table and a number of ejector devices for rejecting unsatisfactory parts, the ejector devices being pneumatically, hydraulically or electrically actuated in response to the operation of time delay relays 28 by signals derived from pneumatic measuring instruments 27 adapted to test the dimensional accuracy of the parts by feelers 26. The parts are fed to holes in the periphery of the turn-table which indexes the parts to the testing stations such as that shown in Fig. 4 which measures the length of the part. A pivoted arm 24 is adjusted in position by a stop screw 25 so that its free end has a position corresponding to an acceptable length for the part 1. If the part has an incorrect length the feeler 26 will be moved upwards or downwards thus causing a signal to be sent to the relay 28 which controls a pneumatic cylinder for operating an ejector in the form of a series of pivoted arms which push the unsatisfactory part through the turn-table and into a collector bin. At a second station, Fig. 5, for testing the diameter of a bore of the part 1 a feeler 31 is pushed into the bore by a number of pivoted arms such as arm 32 actuated by a cam 33. A part having an unsatisfactory bore causes the pneumatic measuring instrument 34 to apply a signal to the relay 35 which operates an ejector device. Other stations are also described for measuring the diameter of the orifice of a nozzle part, for measuring the external diameter of the nozzle part and for testing the leak tightness of the sealing lip of a socket part. At each station cams control the movements of fixing pins for locating the part to be tested and/ or the movements of the feelers which effect the measurement. The cams and the automatic feed which delivers the parts to the turn-table are operated by the motor which indexes the turntable.
