Inventor: BLOMQVIST SEPPO
IPC: B24B53/007
Filed: 1995-07-11
Abstract: A method and an apparatus for sharpening the surface of a grindstone for a pulp grinder. In the method a high-pressure water jet is obliquely projected on the surface of the grindstone for detaching bonding material between abrasive grains, without excessively wearing a medium between grinding segments. The apparatus comprises a nozzle, arranged to spray water obliquely onto the surface of the grindstone and a high-pressure pump for feeding high-pressure water through the nozzle. The nozzle is arranged to be moved by transfer means in the axial direction of the grindstone while the grindstone is being rotated. <IMAGE>

Abstract: 103,183. Tuley, P. S. Jan. 24, 1916. Locking by frictional detents.-The connexions of a spring-applied brake for railway platform trucks are arranged to allow the application of the brakes either by raising or lowering the propelling- handle from ihe service position, and in the service position the tension of the spring is ineffective to move the handle, so that no strain is imposed thereby on the attendant. According to Fig. 1, the connexions include a bent link p connected to, and passing through a slot e<1> in, the handle c of the truck. In the service position of the handle, the pull of the spring h transmitted by the connexions p, k passes through the pivot d of the handle c.

Brush-holders; dynamos, regulating; motors, controlling.-Relates to dynamo-electric machines particularly but not exclusively for use in a system for starting an internal-combustion engine in which a four-pole two-brush generator is changed into a four-brush motor and consists in breaking or making a circuit between a brush and an auxiliary contact with which it is furnished before or after the brush has been removed from or brought into contact with the commutator thereby preventing deterioration of the commutator. As shown in Fig. 1, two of the brushes 21, 22 are connected to the battery 19 through series field windings 6, 7 and auxiliary contacts 36, 35. The brushholders 25, 26 are supported on pivots 27, 28, which also support arms 33, 34 carrying the contacts 36, 35.

Title: Improvements in the manufacture and production of products having high stability to attrition from rubber and the like
IPC: C08C19/00
Filed: 1930-01-16
Abstract: Isomerized.-Rubber and the like in suspension or solution is treated below 100 DEG  C. with organic-inorganic oxonium compounds, free from aldehyde groups and phenolic hydroxyl groups, preferably with the exclusion of oxygen and if desired in the presence of inert organic solvents.  The products have in the vulcanized state hard wearing qualities stated to be due to the transformation of the orientation of the constituent carbon atoms of the rubber-like product from a parallel to a net-like position.  The oxonium compounds are such as are produced from aluminium halides, tin tetrachloride, concentrated sulphuric acid, and the halides or anhydrides of carboxylic acids such as acetic anhydride, acetyl or phthalyl chlorides, or phosgene or organic oxygen compounds free from aldehyde groups or phenolic hydroxyl groups such as ethers. The resulting rubbers may be worked up in the usual manner and show marked differences from untreated rubbers, in solubility, iodine value, &c., and give no indication of a definite X-ray diagram.  In an example 25 parts of phthalyl chloride and 5 parts of aluminium chloride are added to 500 parts of a 5 per cent solution of rubber in benzene.  The mixture is allowed to stand 25 hours at room temperature.  A colourless jelly is obtained by precipitation with alcohol, which yields a hard-wearing product on vulcanization.  The Provisional Specification also describes the treatment of rubber and the like with catalysts such as aluminium chloride and tin tetrachloride instead of with oxonium compounds.

Abstract: 540,086. Resinous condensation products; stiffening textiles. TOOTAL BROADHURST LEE CO., Ltd., and CORTEEN, H. Feb. 1, 1940, No. 1948. [Classes 2 (iii) and 15 (ii)] [Also in Group VIII] A fabric having a tendency to fold along a pre-determined line is made by applying a film-forming stiffening agent to an area along and including both sides of the line and then applying pressure with or without heat to the folded fabric first to the crease and then to the remainder of the fabric to expel more of the stiffening agent from the crease line than from the adjacent areas. Suitable stiffening agents are highly polymerized vinyl acetate and mixtures thereof with polymethylmethacrylate, or far-condensed urea-formaldehyde resins, and are applied in solid form or in solutions or dispersions. Preferably the film-forming material is applied to one face only of the fabric as a high viscosity liquid. Plasticizers, colouring matters and fillers, e.g. titanium dioxide, may be added. The fabric may be pre-treated with a filler or wax to prevent undue penetration. The pressure may be applied by passage through a mangle, hot ironing or squeezing between hinged plates. The example describes the preparation of a urea-formaldehyde resin in which the molecular ratio of urea to formaldehyde is 1:3.8, by dissolving urea in neutral aqueous formaldehyde, adding ammonia and paraformaldehyde and refluxing for a short time. After cooling slightly an aqueous solution of tartaric acid and o-cresol are added and refluxing is continued. Caustic soda solution is added to neutralize and, after cooling, tartaric acid and methyl cyclohexanyl phthalate is added as plasticizer. The invention is applicable to the manufacture of collars and cuffs, particularly the collar described in Specification 512,316, [Group VII].

Abstract: 657,621. Grinding organic material. CLARK, G. M. (Agicide Laboratories, Inc.). Jan. 22, 1948, No. 2011. [Class 59) In a process of finely dividing material of an organic nature sensitive to oxygen and to elevated temperatures, the material, while in a grinding mill, is maintained in a volume ,of steam at super-atmospheric pressure by vaporizing water in the mill, whereby oxygen is excluded and the temperature kept below the critical value. Material, e.g. nutshell, from a hopper 14, Fig. 1, is carried by a screw conveyer 15 through a rotary seal valve 16 to a mill 10 where it is ground in steam at superatmospheric pressure between two contrarotating discs 11, 12, the ground material passing from the mill through an outlet 17 to an interrupted screw conveyer 18. Water is supplied to the mill at such a rate that it is immediately vaporized by the heat developed by the grinding action by a pipe 27 having a valve 26 controlled by a thermostat 24 in the mill outlet 17. A damper controlled vent pipe 22 maintains the required pressure in the mill. Heat may be supplied externally to the mill Water may be introduced into the mill along with the material to be ground. The regulation of the valve 26 may be made responsive to increase in amperage in the grinding motor circuit. The ground product may be carried from the conveyer 18 to a primary air classifier 26<SP>1</SP>, Fig. 2, whence the fines pass to a classifier 36 and receivers 38, 41, and coarse particles are carried by conveyer 27<SP>1</SP> to; (a) an air classifier 32 whence the fines pass to a receiver 34 and coarse particles to a spout 33, and; (b) a spout 29 leading into the spout 33 whence it returns to the mill, the general arrangement being such that the recirculating load in the classifying system is at least three times the weight of the finished product collected. The classifying system is kept at a temperature of for example 180-212‹F. when the mill is at 275‹F., and at a humidity of 85 per cent or more. Specification 657,665 is referred to.
