Title: Improvements in or relating to latch fastening means
IPC: E05B65/32
Filed: 1962-01-03
Abstract: 998,131. Latch fastenings. A. M. AUBOIN, and R. F. V, GIRARD. Jan. 3, 1962 [Jan. 4, 1961], No. 264/62. Heading E2A. A latch fastening means comprises a male part 1 and a female part 2 each adapted to be carried by a respective one of two members to be fastened together, the male part having a convex surface 4 and the female part including a plate 5, a lever 7 pivoted to the plate and a rocking lever 9 pivoted only to the pivotable lever and having a concave surface 12 complementary in shape to the convex surface of the male part and being adapted under the loading of spring means to engage the convex surface of the male part to fasten the two parts together, the arrangement being such that the two parts cannot separate as regards normal movement of the two parts relative to each other until the rocking lever is moved by displacement of the lever pivoted to the plate. The male part is of substantially channel shape in cross-section and has a substantially plane outside surface 3 in addition to the convex outside surface 4. The lever 7 is pivoted to one side of the plate 5 and the pivot 10 for the rocking lever passes through a slot 11 in the plate 5. The concave surface 12 of the rocking lever is one surface of a flange. The plate 5 has a flange provided with a plane surface 6 which is adapted to engage the plane surface 3 of the keeper. The lever 7 is biased by a spring 14 so that the pivot 10 normally tends to engage the end of the slot 11 nearest the surface 6; the rocking lever is biased by a spring 15 to the position shown in Fig. 1. In use, as the parts 1 and 2 move together, the convex surface of the part 7 engages the left hand edge of the flange of the rocking lever and pivots both the rocking lever and the lever 7 anti-clockwise until a position is reached in which the rocking lever can swing clockwise under the influence of its spring 15; the surfaces 4 and 12 then engage each other since the lever 7 swings clockwise under the influence of its spring 14. During the movement of the parts 1 and 12 together, the surfaces 3 and 6 slide on each other. Any separating movement of the parts 1 and 2 causes the surfaces 4 and 12 to grip more tightly. To release the part 1 from the part 2, the lever 7 is rotated anticlockwise which lowers the rocking member out of engagement with the surface 12. In a modification, instead of two springs being used, a single spring connected between the rocking lever and the plate 5 is provided; in a further modification the spring instead of being connected between the rocking lever and the plate is connected to a cam on the pivot 10 which carries the rocking lever. A stop can be provided on the lever 7 to limit movement of the cam.

Patent GB-572383-A (GB)
Title: Improvements in the manufacture of citric acid by fermentation
IPC: C12P7/48
Filed: 1943-01-07
Abstract: In the production of citric acid by the fermentation of carbohydrates by means of Aspergillus Niger, the carbohydrate is treated with cation exchange material to remove the cations having an adverse effect on the yield, the cation exchange material separated and the fermentation effected in the presence of cations of hydrogen, ammonium, potassium and magnesium.  Those ion exchange resins which contain a sulphuric group, e.g. sulphonated phenol aldehyde resins, are preferred as cation exchange material, since these exchange the cation present in the carbohydrate for the hydrogen ion.  The acid left in solution need not be removed, but if desired may be exchanged for the carbonate ion by treatment with other resins; a pH as low as 1.4 may be employed. In an example, diluted molasses are passed through a bed of phenol resin, and when the pH drops to 2.3-3.0, the effluent is collected and passed through a second bed.  Sterilization may then be effected by maintaining the effluent at 80-90 DEG  C. for 10 to 15 minutes.  After adding nutrients, the medium is transferred to fermentation pans and inoculated.  Instead of resins, greensands and natural zeolites may be used.  The Specification as open to inspection under Sect. 91 comprises also the production of any organic compound such as acids, e.g. tartaric, gluconic and oxalic acid, alcohols or ketones by fermentation.  The use of Penicillium, Mucor and Citromyces is mentioned.  This subject-matter does not appear in the Specification as accepted.ALSO:In the production of citric acid by the fermentation of carbohydrates by means of Aspergillus niger, the carbohydrate is treated with cation exchange material to remove the cations having an adverse effect on the yield, the cation exchange material separated and the fermentation effected in the presence of cations of hydrogen, ammonium, potassium and magnesium, Those ion exchange resins which contain a sulphonic group, e.g., sulphonated phenol aldehyde resins are preferred as cation exchange material since these exchange the cation present in the carbohydrate for the hydrogen ion.

Abstract: 661,188. Actuation of switches. BOSCH GES., R. 6, 1949. [Oct. 1, 1948] No. 352/49. Class 38 (v). A switch operated on the reversal of rotation of a rotary member 10, has a pair of axially-spaced but relatively-fixed pawls 15, 16 adapted so that when a striker carried by the rotary member engages one pawl and moves this pawl out of its path, the other pawl is moved into the path which the striker traverses when the direction of rotation of the member 10 is reversed. The striker is formed by a ball 32, a roller or the like which moves under its own inertia along a helical or part helical path formed by a tube 34 secured to the rotary shaft 10. The tube 34 has closed but slotted ends 35, 36 so that depending on the direction of rotation of the shaft 10, the ball 32 is moved to one end of the tube 34 to engage the appropriate pawl 15 or 16 to operate the switch. The tube is slotted so that the end not containing the ball may revolve freely past the other pawl when the latter has been moved down into the path of the tube by the engagement of the ball with the first pawl. The switch has fixed contacts 43, 44 engaging semi-circular contact members 41, 42 carried on a disc 40 secured to and moved by the pawls 15, 16. An overcentre snap-action spring 45 is fixed between the switch frame 50 and a bar 39 interconnecting the pawls 15, 16. The Specification as open to inspection under Sec. 91 describes and illustrates modifications in which (a) the striker is formed by an arm fixed to a sleeve axially movable on the shaft under the control of an inclined slot and pin connection ; (b) the striker is formed by an arm pivoted on an inclined shaft carried by a sleeve rigidly fixed to the shaft 10 ; and (e) the striker is formed by an eccentrically-pivoted, two-armed lever.

Abstract: 376,720. Printing-machines. BRUN, C., Cours, Rhone, France. Jan. 9, 1931, No. 849. Convention date, Jan. 10, 1930. Void [Published under Sect. 91 of the Acts]. [Classes 100 (i) and 100 (ii).] Rotary machines ; inking-apparatus ; feeding and registering webs.-In a rotary printing- machine of the kind in which the web is printed simultaneously with similar patterns on both sides by being passed between coacting printing rollers 3 which serve also as impression rollers one to the other, the material 8 is fed from a stack of folded material between guide bars 41, and is cleaned by carding rollers 30 which are driven in a direction opposite to the feed of the web. The web then passes around tensioning- bars 36 carried by arms 37 pivoted at their centre, and is passed over two rollers 28 formed of freely mounted sections which in the case of irregularly woven materials permit momentarily of unequal speed of different parts of the fabric. The bars 36 are fitted with adjustable checks 39 for regulating the lateral position of the web. The web is fed by a roller 22 to the printing- rollers 3 which are all driven by gearing 16 ..19 from a driving-motor 20. The rollers 3 are preferably constructed as described in Specification 375,771 with felt patterns attached to a rubber covering on rollers, and are adjustably mounted and fitted with inking-rollers 6 also adjustably mounted, which are of different size to prevent permanent indentation of the inking-rollers. The two rollers 6 of each printing-set are immersed in separate ink ducts 9, and each pair of ducts is supplied with ink from a common fountain 10, Fig. 4, arranged at the side of the main frame. The printed web passes over guide rollers 40 to a feed roller 24 which is driven at a speed slightly greater than that of the printing-rollers so as to maintain a tension on the web. The roller 24 is driven by a pulley 25 and a narrow belt 26 which slips on its pulleys if the driving strain exceeds a pre. determined limit. The web is finally delivered to form a folded stack 42.
