Title: Improvements in or relating to multi-part coupling nuts for automatic brake rod adjusting devices
Inventor: GALLUSSER HANS
IPC: B61H15/00
Filed: 1957-07-09
Abstract: 810,434. Automatically adjusting brakes. ATELIERS DES CHARMILLES S.A. July 9, 1957, No. 21677/57. Class 103 (1). [Also in Groups XXIV and XXV] The screwed rod 3 for use in an automatic brake rod adjusting device is engaged by a split nut comprising several, e.g. four, parts 1 held together by at least one annular spiral spring 2 engaging a nut groove 4 whose width is greater than the spring diameter and whose base 5 is inclined to the nut axis. Should one of the parts 1 become axially displaced relatively to the other parts the wide groove prevents damage to the spring, while the inclined base ensures that the spring tends to slide towards the deepest part of the groove and thus tends to bring all the nut parts into engagement with the screw groove.

Title: Improvements in photographic printing processes
IPC: G03B35/24
Filed: 1945-08-24
Abstract: 622,919. Photographic printing processes. LA RELIEPHOGRAPHIE SOC. POUR L'EXPLOITATION DES PROCEDES DE PHOTOGRAPHIE EN RELIEF M. BONNET. Aug. 24, 1945, No. 21763. Convention date, Aug. 10, 1943. [Class 98 (ii)] In order to print a parallax panoramagram picture from a composite strip negative, a light-sensitive emulsion of high translucence, which is carried by a lenticular screen identical with that through which the negative was photographed, is placed in contact with the negative, illuminated therethrough by inactinic light of greater strength than usual and moved until the moire effect has disappeared; the printing and the subsequent developing, fixing and drying of the print are then carried out. As shown, a contact printer comprising a box 2, Fig. 1, including a point-source printing lamp B and another lamp R of intensity higher than the usual safe-light lamp, has superposed on the glass plate 1 thereof a support 3 bearing a composite strip negative 3<SP>1</SP>, which bears a laterally inverted image and which was obtained by the use of a camera employing a lenticular screen and an erector of known type. In contact with this negative is placed the emulsion 6 of a lenticular photographic plate 4, 5, the element 4 of which is identical with the lenticular screen used to obtain the negative 31. The emulsion 6 is of low sensitivity and high translucence, preferably being constituted by chloro-bromide of silver of low density. With lamp R only alight, relative movement between the negative 3<SP>1</SP> and the lenticular photographic plate is effected until no moires are to be seen. Printing from the negative 3<SP>1</SP> is then carried out, using the lamp B.

Title: Improvements in the manufacture of cellulose esters
IPC: C08B3/00
Filed: 1948-08-18
Abstract: Cellulose is esterified with the anhydride of an aliphatic acid having 2-4 carbon atoms in the molecule in presence of enough of an aliphatic acid of 2-4 carbon atoms to dissolve the cellulose ester formed and in presence of an inorganic acid-reacting catalyst; the cellulose is mixed with all the anhydride to be used and with the solvent acid and catalyst; the temperature is maintained below 40 DEG C. until considerably more than half the cellulose has dissolved as ester and the rate of reaction has greatly decreased; and the temperature is then raised or allowed to rise above 40 DEG  C. and so maintained until esterification is substantially complete. Preferably the temperature is initially allowed to rise rapidly to a maximum between 20 DEG  and 40 DEG  C. and kept at this maximum until considerably more than half the cellulose has dissolved as ester.  It is then raised to 40-60 DEG  C. for the remainder of the reaction. For high viscosity cellulose acetate the greater part of the esterification may take place at a temperature rising to a maximum of 20-25 DEG  C.  When esterification is complete and substantially no undissolved fibres remain, the cellulose ester may be hydrolysed while in solution until it has solubility in acetone.  In an example, cellulose is pretreated at 25 DEG  C. with a mixture of sulphuric acid, water, and glacial acetic acid.  It is then acetylated with a mixture of acetic anhydride, glacial acetic acid, and sulphuric acid which has been cooled to 5 DEG  C.  The temperature is allowed to rise to 25 DEG  C. and is maintained at this temperature for 40 minutes.  The temperature is then allowed to rise to 42 DEG  C. and maintained at this temperature for 29 minutes.  Water is added and part of the sulphuric acid is neutralized, after which the cellulose acetate is ripened until it has an acetyl value calculated as acetic acid of 56 per cent.  In another example, the temperature is allowed to rise to 25 DEG  C. in the first stage and afterwards allowed to rise to 43 DEG  C.

Title: Improvements in or relating to variable displacement pump
IPC: F16H61/46
Filed: 1954-07-28
Abstract: 774,307. Fluid-pressure servomotor control systems. SUNDSTRAND MACHINE TOOL CO. July 28,1954 [Aug. 20, 1953], No. 22043/54. Class 135. A fluid-pressure servomotor control means for a variable displacement pump 15 operated from a power source includes displacement varying means 65 movable between two extreme positions, a fluid-pressure producing device 30, 31 driven by the power source, fluid-pressure operated means 60 for moving the displacement varying means, means 88 biasing the displacement means to a neutral position between the extreme positions, and means 50 operable upon a drop in fluid pressure to divert fluid from the fluid-pressure operated means to permit the biasing means to move the displacement means. In an hydraulic transmission from a variable displacement multiple piston pump 15 rotated from gear 26, through multiple piston hydraulic motor 22, fixed swash plate 24 and shaft 25-to an output gear 27, the pump wobbler 18 is adjusted by piston 60 under the control of a governor 52 responsive to the speed of gear 27. Aircraft engine lubricating pumps 30, 31 supply oil via passages 34, 37, 38 to a valve chamber located between the pump and motor for maintaining the pistons against their wobblers. The oil then passes to lubricating points 46 via passages 39, 42. Oil is also taken via pipe 47 and spring-loaded shuttle valve 50, maintained open by the oil pressure, to supply the governor and produce a control pressure in pipes 53, 54. Should the oil pressure fail, e.g. when the aircraft engine driving the gear 26 is shut down, the valve 50 moves to direct the control pressure oil to drain via pipe 73 and the wobbler is moved to pump zero displacement position by a spring-loaded plunger 88 and all the pump pistons 16 remain in abutment with the wobbler. The wobbler arm 65 is held between two pistons rods 63, 64 connected to two pistons 61, 62 pressed together by the cylinder pressure. The rods may be spring pressed to grip the arm and connected to a single spring- loaded piston, thus dispensing with the plunger 88,

Title: Multi-cylinder internal combustion engine
IPC: F02M35/10
Filed: 1975-05-22
Abstract: 1504954 Inlet manifolds NISSAN MOTOR CO Ltd 22 May 1975 [22 May 1974] 22273/75 Heading F1B A multi-cylinder engine in which the cylinders are divided into a first group and a second group, and which has an afterburner and a carburetter also has an inlet manifold comprising a main runner which communicates with the carburetter, a first portion which communicates directly with a first group of branch runners leading to the first group of cylinders, a second portion which communicates directly with a second group of branch runners leading to the second group of cylinders and is characterized in that the main runner is constructed to feed a larger proportion of the fuel in the air/fuel mixture from the carburetter into the second group of cylinders through the second portion of the main runner than into the first group of cylinders through the first portion of the main runner and the carburetter is set to produce such a mixture that the first and second groups of cylinders are fed with mixtures which are leaner and richer than stoichiometric respectively. In a first embodiment, Fig. 1, the carburetter is connected to opening 24, cylinders C 1  and C 4  constitute the first group and cylinders C 2  and C 3  form the second group. The first portion of main runner 20 consists of parts 20a which have a larger internal cross-sectional area than the second portion 20b. Assuming a firing order of C 1 , C 3 , C 4 , C 2 , when cylinder C 1  inducts fuel/air mixture then, of the fuel constituents which are difficult to vapourize or which have the higher specific gravity, a proportion remain temporarily in main runner part 20a. During the induction strokes of cylinders C 3  and C 4 , the retained fuel vapourizes and is then drawn into cylinder C 2  when that cylinder makes its induction stroke. The cylinders C 2  and C 3 , i.e. the second group thus receive a mixture containing a greater proportion of fuel than the cylinders C 1  and C 4 . In a second embodiment, Fig. 3 (not shown) the main runner is of the same cross-sectional area throughout its length, but the carburetter opening 24 is situated between the branch runners 22c and 22d. In a third embodiment, Fig. 4, the main runner is uniform throughout its length and has a well 26a, 26b formed adjacent the branch runner leading to each cylinder of the first group, fuel being retained in these wells and subsequently drawn into the cylinders of the second group. In a fourth embodiment, Fig. 6, grooves 28a and 28b are formed in the floor of the manifold and extend into the branch runners leading to cylinders 22b and 22c i.e. the second group. In a fifth embodiment, Figs. 8 and 9, the main runner is of uniform crosssection except that there is a projection 30 between opening 24 and runner 22b, so that cylinders C 1  and C 2  receive a weaker mixture than cylinders C 3  and C 4 . In the sixth embodiment, Fig. 10, the features of the previous embodiments are combined, so that cylinders C 1  and C 2  receive the weaker mixture.

Title: Improvements in or relating to the manufacture of artificial filaments or threads
IPC: D01D7/02
Filed: 1929-07-20
Abstract: <PICT:0340471/IV/1> In the manufacture of filaments or threads by the dry-spinning method, the threads 6 are, continuously with their production, wound and twisted by leading them into a centrifugal box of relatively small diameter, particularly 3 to 4 inches, rotated at a very high speed, e.g. 12000-20000 or more revolutions per minute. High speeds of spinning comparable with those of the cap-spinning process described in Specification 198,023, [Class 2 (ii), Cellulose &c.), are thereby attained.  To avoid limitation in the size of the yarn package, the length of the box is increased, e.g. to 6, 7, 8 or 10 inches.  As shown, the thread 3 formed in the cell 2 is led over a guide 6 and draw roller 7 to a sizing-roller 10 and thence through a guide 13 to the box 15 which is rotated by a belt 16 at a speed of 15000-20000 or more revolutions per minute.  To facilitate starting up, the end of the thread may be led into the box through a tube or guide down which a stream of water is directed; alternatively an ejector device 18 of the type described in Specification 340,504, or a guide device of the kind described in Specification 340,505 may be employed. Lubricating or moistening devices may be arranged in the path of the thread.

Title: An improved process for making transparent films, foils or skins
Filed: 1933-08-10
Abstract: In a process for making transparent films, foils, or skins, water insoluble polysaccharides having in their naturally occurring state a particle fineness of between approximately 0,05 mm. and 0,3 micron or reduced to this particle size by dry grinding are swollen in an aqueous medium with avoidance of all chemical change, and the resulting hydrosol is dried in thin layers to products having no apparent fibrous structure.  100 parts of pine wood cellulose obtained by the sulphite process are shredded, and 6 parts of dry sodium hydroxide are added and the mixture is ground in a heatable ball mill for 5 hours at 90 DEG  C. to a size of approximately 0,4--0,3 micron.  It is then mixed with 700 parts of water and stirred, the stirrer making about 10 revolutions per minute for 20 hours at room temperature.  The viscous solution is then lavered to form foils.  10 per cent of sodium hydroxide may be added and the time of swelling shortened, e.g. to 2 hours by raising the temperature to 55 DEG  C.  Arabin and xylene may be similarly worked up.  The swelling of the substance is preferably promoted by elevating the temperature or by using as swelling agents, bases, more particularly free alkalies or salts. In another example, rice starch is ground with dry magnesium chloride, swollen by the addition of water and the hydrosol layered to form foils, and in a third example equal parts of pine wood cellulose and of dextrin are ground with sodium hydroxide and then treated as in the other examples.  The foils may be made waterproof or non-inflammable with oils, resin solutions, lacs, cellulose esters, alkali metal bromides or starch solutions. Specification 155,836 (as open to inspection under Sect. 91) [Class 2 (ii)], is referred to.  Reference has been directed by the Comptroller to Specification 18493/08, [Class 2].ALSO:In a process for making transparent films, foils, or skins, water insoluble polysaccharides having in their naturally occurring state a particle fineness of between approximately 0,05 mm. and 0,3 micron or reduced to that size by dry grinding are swollen in an aqueous medium with avoidance of all chemical change, and the resulting hydrosol is dried in thin layers to products having no apparent fibrous structure.  100 parts of rice starch of commerical quality are ground for about 1 hour at normal temperature in a colloid mill with 8 parts of dry magnesium chloride, and the product is sorted to give a particle size of 0,05 to 0,02 mms.
