Abstract: 957,413. Mulling shoe uppers. FORMULAST CORPORATION. May 12, 1960 [Sept. 3, 1959], No. 16878/60. Heading A3B. A leather upper is mulled in an atmosphere having a temperature above 130F., preferably between 140F. and 180F., and 100% relative humidity for a restricted time, e.g. 3 minutes, so that the moisture content is at a greater concentration at at least one surface than it is in the upper as a whole. Preferably the time is such that the moisture content at at least one surface is not less than 18%. A fine hot water mist spray may be directed on to the leather during mulling. As shown the uppers 58 are carried by a conveyer 36 through an open ended chamber 10 containing a hot water trough 22 with perforated steam pipes 24 for bubbling steam through the water to produce the required atmosphere. The uppers are removed via the shoot 50. A plurality of nozzles 54 produce a fine mist of hot water which falls on to the upper, grain, surface of the upper. The conveyer may be part of an endless conveyer leading to successive lasting stations, and may carry last supports. Specification 933,183 is referred to.

Abstract: 803,494. Electric control systems. INGERSOLL MILLING MACHINE CO. May 31, 1956, No. 16896/56. Class 40 (1). In electric remote-control apparatus for selectively operating any one of a number of relays L1-L8 (Fig. 1), each relay is connected in the anode circuit of a thyratron T1-T8 having a control grid G and shield grid G<SP>1</SP> whose bias voltages are determined by manually operated switches S2-S8 at a remote control station, the arrangement being such that there are only two wires connecting the control station to the operating station, and only one of the load relays L1-L8 can be operated at a time. The basic bias for the control grids G of the tubes T1-T8 is obtained from a potential divider chain r1-r7 connected across a battery 20, and the basic bias for the shield grids G<SP>1</SP> is obtained from a second potential divider r1<SP>1</SP>-r7<SP>1</SP> connected across a battery 24. Included in each bias circuit are the two parts 14a, 14b of a resistor 14 which is in series with a battery 15 and a number of control resistors R2-R8 selectively short-circuited by the switches S2-S8, so that the P.D. across resistor 14 is determined by the switches S2-S8, and is algebraically added to the bias potentials on the grids G, G<SP>1</SP> to determine which thyratron should conduct and operate its load relay. One normally closed contact of each relay is included in the anode circuit of all the previous tubes to prevent them from firing when that tube is conducting. An auxiliary relay AR may be added, to be operated on conduction of tube T1, which completes its own holding circuit and continues after tube T1 has ceased to conduct.

W.; 3555, Edwards Road, Cincinnati, Ohio, U.S.A.) June 2, 1930, No. 16980. Convention date, June 4, 1929. Void [Published under Sect. 91 of the Acts]. [Class 117.] In a selector mechanism for delivering work pieces such as conical rollers to a grinding machine, the work pieces pass successively from a hopper through a feed tube to a table from which they are rolled into a slot where they are suspended with the small end downwards while they are moved along the slot into alignment with a second feed tube. The feed of the blanks to the grinding throat is effected by a shaft driven from an electric motor operating, through links 18, 19, 28, an agitator tube 25. This tube rides over an inner feed tube 26 and serves to agitate the blanks contained in a hopper 22 and cause them to pass in a line down the feed tube which has a curved portion 30 terminating in an inclined table 31 on to which the blanks 13 are successively delivered, the forward movement of the blank being arrested by a stop 50. The blank is then moved laterally by a pusher 47 into a slot 33, the width of which is adjusted by a guide plate 35 so that the blank hangs vertically with the small end downwards, while it is moved along the slot by a second pusher 43 until it reaches a discharge opening 32 through which it drops into a feed tube 34 leading to the grinding throat. The pushers 47, 43 are both resiliently controlled by a cam lever pivoted at 39 and operated by a link 36 connected to a collar by the agitator tube. One end of the cam lever bears on the upper arm 42 of the pusher 43 and the other arm bears on a lug on an arm 45, actuating the pusher 47, the movements of the pushers in the operative direction being controlled by a spring 48 connecting the members 42, 45.

Abstract: 1502346 Positive clutches; clutch-brake combinations; change speed gears ZAHNRADFABRIK FRIEDRICHSHAFEN AG 25 April 1975 [26 April 1974] 17238/75 Headings F2C F2D and F2L In a friction synchronized positive clutch or brake (Fig. 7, not shown) for a change speed gear wherein axial engaging movement of a two-part sleeve 4, 11 is baulked until synchronism occurs by teeth on the sleeve 11 abutting teeth on a synchronizing ring 5, the initial axial movement of the sleeve 4, 11 is transmitted to the synchronizing ring 5 by radially resilient axially extending spring tongues 10 fast with a rim 6 riveted to the sleeve 11 (or synchronizing ring 5) and engaging a groove 21 in the synchronizing ring 5 (or sleeve 11). As shown in a double positive clutch for selectively connecting gears 1, 2 to a shaft 3, a pair of rims 6 having spring tongues 10 are riveted to the clutch sleeve 11. The spring tongues 10 engage, with lost motion, between radial projections (7, 8) of the synchronizing ring 5 so that when the latter frictionally engages the gear 1 or 2 the ring 5 rotates relative to the sleeve 11 to a position in which its teeth prevent further axial movement of the inner part 4 of the clutch sleeve. When synchronism is attained bevelled ends of the clutch teeth on the sleeve 4 return the synchronizing ring 5 to a position in which the clutch teeth on the sleeve 4 can pass through the teeth on the ring 5 into engagement with teeth on the gear 1 or 2. During the further clutch engaging movement of the clutch sleeve 4, 11, the spring tongues 10 ride out of the grooves 21. In Figs. 4-6 (not shown) the spring tongues press radially outwardly into internal grooves of the synchronizing rings. In Fig. 7 (not shown) the spring tongue rims (76) are riveted to the synchronizing rings (75) and the spring tongues (70) are biased radially outwardly into engagement with grooves (77) in an axially slidable sleeve (71). The sleeve (71) additionally forms the ring gear of a sun-ring planet train and movement of the sleeve (71) in one direction engages a clutch connecting the sleeve (71) to an output planet carrier (72) for direct drive, whilst movement of the sleeve (71) in the opposite direction engages a positive brake which holds the sleeve (71) for reduced ratio.

Abstract: 791,425. Packaging-machines. NATIONAL DAIRY PRODUCTS CORPORATION. June 5, 1956 [June 22, 1955], No. 17321/56. Class 94(1). Articles are packaged by enclosing them in a tube formed of flexible sheet material, replacing the air in the tube by preservative gas and sealing and cutting the tube between the articles to produce separate packages. The tube may be formed about a series of spaced articles from a single web, or two webs, one having on it the spaced articles, may be joined along two side seams. In a machine for producing the packages from a single web, the web 11 is led from a roll 9 around smoothing rollers 51, 65, 67 to a tubing station 15, the articles U being placed on the web between guides 55 during its passage across a table 13. A hold-down roller 81. prevents displacement of the articles. Adjacent the tubing station is a support 85 for a preservative gas injecting pipe 19 which extends within the tube above the articles to the vicinity of a pressing station 23. The tube seam 61 is sealed by heated rollers 87, 88 and is folded down by means including a guide 93 and roller 91, the axis of the latter being on the skew to produce a straightening and tightening action on the seam. At the pressing station, resilient rollers 105, 106 press the tube about the articles to expel as much gas and air as possible and the tube passes between two pairs of driven rollers 117a, 118a set on the skew and driven at a faster rate than the tube travel, these rollers preventing wrinkling. The tube is now sealed and cut between the articles by periodically operating rollers 123, 124 having axially extending raised portions which contact each other between the articles but allow the articles themselves to pass. The raised portions consist of heated sealing areas along the centre of which runs cutting means in the form of a knife and anvil. The completed packages P are removed by a conveyer 144. The roll 9 as shown includes a waste interleaved separating sheet which is wound onto a roller 43. The rollers 123, 124 may be controlled by cam means or by photo-electric means (not shown) responsive to markings on the tube.

Filed: 1928-06-16
Abstract: 298,972. Hercules Powder Co., (Assignees of Johnston, A. C.). Oct. 18, 1927, [Convention date]. Esters of resin acids are produced by treating a resin acid such as abietic acid or a resin such as wood rosin or a resin containing pimaric acid, with an alkyl chloride or bromide in presence of an alkali, preferably in solution, in an alcohol, for example, ethyl, propyl, butyl, or amyl alcohol. The alkyl chlorides and bromides mentioned are ethyl and amyl chlorides, and ethyl and butyl bromides, and the alkalies caustic soda or potash, calcium hydrate, or sodium carbonate. In an example, ethyl abietate is produced by dissolving sodium hydroxide and rosin in ethyl alcohol and heating with ethyl chloride at 130‹ C. under pressure; the sodium chloride is removed by filtration and the alcohol by distillation, the ethyl abietate being then distilled under reduced pressure; the ester may be redistilled with a little soda ash, or the soda ash may be added to the reaction product before distillation. In a similar manner n-butyl abietate is obtained from a mixture of sodium hydroxide, water, alcohol, rosin, and butyl bromide, and namvl abietate from a mixture of sodium hydroxide, alcohol, rosin, and n-amyl chloride. A mixture of esters may be produced by using mixed alkyl chlorides, such as butyl. amyl, and hexyl chlorides. The process may be used for the production of the methyl, n-propyl, isopropyl, isobutyl, and isoamyl esters of abietic acid. The Specification as open to inspection under Sect. 91 (3) (a) comprises the use in the process described above of alkyl halides in general. This subject-matter does not appear in the Specification as accepted.
