Filed: 1929-05-02
Abstract: 328,795. Bullock, P. W. May 2, 1029. Fastening; goloshes. - Boots, shoes, slippers, goloshes, and the like have the counter made wholly or partly of a soft flexible strip formed in continuity with and connecting the two sides of the upper, and of larger size than that required to fit the foot, and is adapted to be folded on itself once only at one or both sides of the foot to lie closely against the heel. It is retained in its folded condition by a flap united to the upper, preferably on the inside of the shoe, and tapering into a strap provided with retaining means for securing it to the other side of the shoe &c. As shown in Fig. 3, a flexible strip 2<a>, 2b of waterproof material, such as soft leather, connects the two parts of the upper 1 and is lasted in at the heel. It is folded as shown and a securing flap 3, fastened to or integral with the upper 1, is employed to hold the folded counter in position. The fastening means for securing the free end of the flap 3 may be of the kind disclosed in Specification 328,267, [Class 44, Fastenings, Lock &c.]. The counter may be in two parts joined together, one part being integral with one part of the upper and having the other part secured thereto and to the securing flap. Alternatively, the ends 2<c>, 2<d>, Fig. 7, of the counter portion of the upper 1 which is split vertically at or adjacent the heel centre, and the securing flap is in two overlapping parts 5, 6, one end of part 5 being secured to one portion of upper 1 and tapering down on its lower edge to where centre of heel is located in, while the other part 6 overlaps part 5 on inside of outside and may be formed integrally with the shoe. This flap when fastened exerts pressure on heel in two different directions. The second part 5 of flap may in some cases be dispensed with. The invention is also described as applied to goloshes, with or without a heel portion.

Title: Improvements in fine reduction mills and method of fine reduction
IPC: B02C17/14
Filed: 1945-05-31
Abstract: 601,608. Grinding-mills. CROSS, E. J. (Nordberg Manufacturing Co.). May 31, 1945, No. 13694. [Class 59] A method of grinding materials includes the following steps: maintaining in a grinding zone superjacent to a gyratory impacting member a mixed mass comprising particles of material to be ground and separate loose impacting elements; gyrating the said impacting member at a sufficient speed and with sufficient amplitude of movement to throw a substantial proportion of the mixed mass upwardly and clear of the impacting member, through a distance sufficient to ensure an ensuing free fall of the upwardly projected mass; and thereafter catching the falling mass upon an upwardly moving part of said impacting member so that the ensuing impact enhances the crushing action of the loose impact elements in the falling mass, the impactive action progressing sequentially around the grinding zone and the inertia of that proportion of the mixed mass which is impacted by the gyratory impacting member at any given instant being substantially less than the inertia of said impacting member. A shaft 15, driven from a shaft 6, Fig. 2, by gearing 17, 16 is mounted in bearings 14, 21 in a housing sleeve 9, 10, 11 mounted between I beams 1. A spherical bearing element 23 mounted on the upper end of the sleeve 9 engages a concave spherical element 42 to support the mill proper, which comprises a housing 30, 33, with lining 70, 76, 78, having a sleeve part 34 fastened at its upper end to a sleeve 40 carrying the element 42. The sleeve 34 is secured at its lower end to a member 68 having a sleeve 62 in bearings 61 of which an eccentric arm 18, which forms part of the shaft 15, engages, so that, as the shaft 15 rotates, the member 68 and thus the mill is given the required gyratory movement. To prevent bodily rotation of the mill housing it is flexibly connected by compression bolts 93, Fig. 2, spacers 94 and rubber masses 96, 98 to an I beam. Material from a feed spout 51 falls onto a cover member 50 on the sleeve 40 and drops through an aperture 32 into the mill housing. The action of the mill moves the fines toward an outlet 72 around the sleeve 34 and into an outlet chute 75. The grinding bodies may be balls or rings surrounding the centre sleeve. The amplitude and speed of the gyration are so related as to obtain the best impacting effect, which occurs when the falling mass hits the bottom impacting plate of the mill when said plate is moving upwardly at its maximum velocity. Lubrication oil passes from the interior of the sleeve 40 through channels 43 in the member 42, over the spherical surface 23, through channels 46 and over the shaft bearings 21, 14 down to a gear pump 101 and is then pumped back to the sleeve 40 through a pipe 100. The mill may be used for wet grinding. In a modification described the gyrating bowl is positioned below the driving shaft 6.

Title: Process for the production of alkyl-cellulose compositions in a finely pulverisable form
IPC: C08B11/02
Filed: 1951-06-08
Abstract: Alkyl-celluloses soluble in cold water and insoluble in hot water are converted into a finely pulverizable form by mixing an aqueous solution of the alkyl cellulose with a water-soluble salt having a precipitating action in sufficient concentration to precipitate the alkyl cellulose, and filtering and drying the precipitate.  The salt may be added in solid form or as a concentrated aqueous solution and may be a salt of an alkali metal or alkaline earth metal, e.g. sodium chloride or sulphate.  After the addition of the salt the mixture is preferably heated to about 50-100 DEG  C. before filtration.  The alkyl cellulose may be a methyl cellulose or an alkyl cellulose containing some oxyalkyl groups, e.g. ethyl-oxyethyl-cellulose.  In an example 10 parts by weight of a methyl cellulose soluble in cold water are stirred in 200 parts by volume of water at 60 DEG  C., the resulting suspension is mixed with 200 parts by volume of cold water, and the mixture is cooled to 25 DEG  C.  Four additions of 100 parts by volume of a saturated aqueous solution of sodium chloride are made at intervals of a few minutes, whereby a flocculent precipitate is formed which is stirred for a further hour.  The mixture is then heated to 90 DEG  C. by introducing steam, and filtered with suction. The filter cake is partially dried by suction or pressure and the drying is then completed by exposing the material spread out in loose form to a current of air at 90-100 DEG  C.  A granular material is obtained which contains 20-30 per cent of sodium chloride and can be easily ground to fine powder in a percussion mill.  In other examples, sodium sulphate and magnesium sulphate respectively are used as precipitating salts.

Title: A new antibiotic melrosporus
Filed: 1965-04-01
Abstract: <PICT:1100731/C2/1> <PICT:1100731/C2/2> An antibiotic, melrosporus, effective against gram-positive and gram-negative bacteria, is produced by the submerged aerobic cultivation of a melrosporus-producing strain of Streptomyces fercens var. melrosporus, e.g. NRRL 3117, in an aqueous nutrient medium containing a source of assimilable carbohydrate and nitrogen until substantial activity is imparted to said medium and isolating the melrosporus so produced. Melrosporus may be isolated by the use of solvent extraction, liquid-liquid distribution in a Craig apparatus, partition chromatography, adsorbents and crystallization from solvents. In one procedure, melrosporus is separated from the mycelium by filtration or centrifugation followed by solvent extraction with a water-immiscible solvent for melrosporus, e.g. ethyl acetate, and isolation from the extract by evaporation to dryness or freeze-drying.  Alternatively, melrosporus may be separated from the culture medium by means of a strongly basic anion exchange resin and from the filtered culture medium or organic extract by adsorption using e.g. silicic acid, decolourizing carbon or resin followed by elution.  Melrosporus, an acidic white substance, is soluble in water, methanol, ethanol, ethyl acetate, 1-butanol and 2-butanol, slightly soluble in ether, hexane and cyclohexane, and contains C 41.43%, 41.68%; H 5.16%, 5.06%; N 9.36%, 9.59%; O 43.75% and has a molecular weight of 147 giving a formula of C5H7NO4, [a ]25D = +4 DEG  (C, 0.7, H2O) and U.V. in 95% ethanol and I.R. spectra in mineral oil as shown in Figs. 1 and 2.  Salts are formed with alkali metals, alkaline earth metals, organic bases and polyamines.  Melrosporus or salts thereof may be used to prevent or reduce the growth of bacteria and fungi in animals such as mammals, birds, fish and reptiles.  It is useful for preventing the infection of silkworms caused by pathogenic cultures of B. subtilis.  It may also be added to a feed mix or supplement for animals to promote the growth thereof.  Melrosporus is also useful as a general disinfectant, bacteriostatic rinse and fungicide.ALSO:The antibiotic melrosporus or salts thereof with alkali metals, alkaline earth metals, organic bases and polyamines may be added to a feed mix as supplement for animals such as birds, fish and reptiles to promote the growth thereof.  Melrosporus is produced by the submerged aerobic cultivation of a melrosporus producing strain of Streptomyces fervens var. metrosporus, e.g. NRRL 3117. It has the empirical formula C5H7NO4.ALSO:The antibiotic melrosporus, or salts thereof with alkali metals, alkaline earth metals, organic bases and polyamines, are useful as a general disinfectant, bacteriostatic rinse, fungicide and antibacterial agent.  They may be used to treat plants, animals particularly silkworms and to minimize or prevent odour in fish and fish crates.  A disinfectant composition comprises the antibiotic melrosporus together with a diluent in which the antibiotic is soluble.  It may be used to preserve oil, paper and fabrics.

Title: Coin freed vending machine
IPC: G07F5/26
Filed: 1936-05-16
Abstract: 458,226. Coin-freed article-delivery apparatus. BRUS, G. J., 19<1>, Van Tuyll Van Serooskerkenweg, Amsterdam. May 16, 1936, No. 13964. [Class 27] Articles stored in separate compartments.- In a coin-freed vending machine comprising goods compartments 2 closed by shutters 4 controlled by locking pieces 11 insertable between a row of blocking members 12 held in engagement by a spring 22 whereby only one shutter can be opened after the blocking members have been freed for displacement by insertion of a coin, each locking piece remains with a part projecting between two successive blocking members when its shutter is closed, and is held in contact with a blocking member and an operating part, e.g. a quadrant 7, secured to the shutter, under the action of the spring 22. The blocking members are thus separated, and the remaining shutters locked immediately a shutter is opened. As shown in Figs. 1 and 4, the blocking members are carried in a channelled guide 8 which, together with the shutter quadrants 7, are located in a compartment of the main casing to one side of the compartments 2. Each locking piece has a bevelled surface 16 permanently in engagement with a corresponding surface 21 of the lower co-operating blocking member 12, so that, when the locking piece is displaced by the opening of its shutter, all the lower blocking members are moved downwardly to lock all the shutters below that opened. Each locking piece also has a rectangular recess 10 normally opposite a similar clearance recess 20 in the upper cooperating blocking member so that, when the locking piece is displaced, the part lying behind its recess 10 enters the recess 20 in the blocking member and prevents downward movement of all the upper blocking members and consequently opening of any shutter above that first opened. In the modification of Fig. 5, the locking pieces 11 have no rectangular recesses, but lock the upper blocking members by engagement with their lowermost surfaces 18.

Title: Improved wrapping or wrapping and addressing machine
IPC: B65B25/14
Filed: 1923-05-29
Abstract: 207,756. Wieringa, J. May 29, 1923. Packeting by wrapping-up.-Relates to a machine for wrapping or for wrapping and addressing newspapers and other publications. The wrapping paper 150, Fig 1, is unwound from a roll and passes over rollers 43 - - 45 between a flanged feed roller 46 and a presser roll 47, and between gripping devices 50, 51. Rollers 40, 41, perforate the web, the feed of the newspaper detaching a wrapper, sufficiently large to encircle it and to leave a flap, from the web while the gripping devices are operative. The newspapers &c. are fed by arms 8 pivoted at 2 on slides 9 and operated by a rod 16, on endless chains 12, which engages a slotted arm 6 so that when the rod 16 is moving to the right to feed a newspaper the arms 8 are elevated through slots and above the level of the table 4, and are depressed during the return stroke. At the time of feed a gate 30 is raised by a roller 37, Fig. 3, on the rod 16 which depresses a rail 36 on a frame 34 oscillating about a pivot 35, raising rods 21 which elevate the gate against the action of springs 33. The book and wrapper are pressed between relatively adjustable rubber rolls 18, 19 positively rotated to coincide with the feed. Clips 112, 113 are at that moment elevated so as to be opposite the line of fed and receive the partially wrapped newspaper. The clips 112, 113, are mounted on rods 110, 111 passing through slides 114, 115, reciprocating on horizontal slides 116, 117. The slides are moved by a cam disc 94 through an arm pivoted at 120 and connected to a link 121 actuating a toothed sector 123 in engagement with a rack 125. The upper clips move upwards before the lower clips to ensure catching the partially wrapped newspaper A stamp 89 is then depressed to the position shown in Fig. 1, arms 130, 107 bearing on the rods 110, 111 to carry the slides down. The stamp is depressed by links 90, 91, on a crank pin 92 and carries a series of rollers 100, 102, 103, for transferring paste from a receptacle, the roller 100 being rotated by a pawl 98 and ratchet 97. During the descent of the stamp, a vertical folding plate 106, Fig. 3, turns up the flap into engagement with the pasting means. After the address has been stencilled on the wrapper, the partially wrapped packet is passed between the lower rollers 19, 20 which fold down the outstanding flap and deliver the packet from the machine.

Title: Electric motor control system
IPC: B66C13/26
Filed: 1963-04-10
Abstract: 988,338. Automatic speed control systems. HARNISCHFEGER CORPORATION. April 10, 1963 [April 23, 1962], No.14315/63. Heading G3R. [Also in Division H2] The invention relates to a hoist control system of the kind described in Specification 847,665, employing an induction motor and electrodynamic brake, but uses magnetic amplifiers and silicon controlled rectifiers instead of electron discharge tubes. Speed control. The "induction master" controller 22 energizes the motor 15 and motor brake 19 over a reversing contactor 23 and supplies an A.C. reference voltage which is rectified and compared with a speed signal derived from the motor rotor through a saturable transformer and rectifier (i.e. speed signal depends on rotor frequency and is independent of rotor voltage). The error signal is applied to the control windings of a pair of magnetic amplifiers 24 controlling siliconcontrolled-rectifiers 26, 27 to energize saturable reactor 16 in the rotor circuit, or an electrodynamic brake 17, according to the sense of the error. The D. C. speed signal may be differentiated by an RC network Fig. 9 (not shown) to provide an "anti-hunting" feedback signal. Alternatives. The Specification states that if the motor is driving a traverse control the electrodynamic brake may be omitted. Plugging. When the motor is plugged the speed signal amplitude indicates "slip" in excess of 100%, and this value turns on a trigger pair 100 Fig. 7 (not shown) controlling a transistor "switch" 99 to energize control windings on the magnetic amplifiers so that the electro-dynamic brake is full on and the rotor saturable reactor is "off". The trigger pair does not revert to the off position until the speed signal is nearly zero. Alternatively for traverse drives the bias signal may be made proportional to motor current so that the master regulator determines the motor torque, or plugging may be detected as above to disconnect the speed feed-back signal leaving "open-loop" control of the rotor reactor. Rotor resistance arrangements. Figs. 10,11 (not shown). The permanent resistance A in series with the saturable reactor C may be kept low and a starting resistance B connected in parallel therewith to provide improved low-speed torque, Fig. 10A. If it is desired to have the minimum motor torque up to 100% in the "hoist" direction and less in the "lower" direction contacts E may be provided to disconnect the rotor resistance when lowering, Fig. 10B. Where large motors are used for fast acceleration and the load requires considerably less than the rated motor torque, only a resistance A in series with the reactor C is required. Off-position bias. Fig. 8 (not shown). When the control signal and the motor speed signal are zero, bias from a transistorised circuit 108 reduces output of the brake-magnetic-amplifier to prevent overheating. Application of either the control-signal or a speed-signal trips the circuit to remove this bias.
