IPC: A63H33/06
Filed: 1932-07-11
Abstract: 408,924. Constructional toys. BUB, K., 48, Gostenhofer Hauptstrasse, Nuremberg, Germany. July 11, 1932, No. 19579. Void [Abridged as open to inspection under Sect. 91 of the Acts, June 22, 1933]. [Class 132 (iii).] A set of elements for use in forming model structures includes a bar a, Figs. 2 and 3, of channel section reinforced by longitudinal ribs c in the webs. The bars are connected by elements f, Fig. 5, the flanges at each end of a bar being cut away to enable the bar to take over the peripheral part i of the connecting element, in which position the hook-like end portions k of the flanges embrace one of the radial portions g of the element. The bar is held in engagement with the connecting element by a substantially U-shaped member s, Fig. 7, fitting over and slidable upon the bar. In operative position, Fig. 11, the cut-away webs u of the slide take under the peripheral part of the connecting member, and a projection y on the resilient web of the slide abuts the end of the bar. The slides are manoeuvred in assembling and dismantling by a gripping flange z or alternatively by means of a tool adapted to be engaged within an aperture in the slide, the bar being slotted to enable adequate engagement of the tool. The flanges of the slides may be formed with re-entrant portions to maintain the slides upon the bars. Additional forms of connecting elements are shown in Figs. 17 and 19, the former being bent at 90‹ about the line 11 and the latter twice at 45‹ about the lines 11<1>.

IPC: C14C3/24
Filed: 1954-07-05
Abstract: 777,474. Tanning leather. ST. LAWRENCE CORPORATION, Ltd. July 5, 1954, No. 19652/54. Class 76. Hides are tanned by impregnating with an aqueous solution containing a water-soluble aldehyde, a water-soluble dibasic acid amide or a water-soluble condensation product of said aldehyde and said amide, together with a watersoluble lignin material at a pH effective to maintain the active agents in solution and to cause them to penetrate the stock and thereafter adjusting the pH to precipitate the active agents in insoluble form within and on the hide to tan it. As aldehydes the following may be used: formaldehyde, furfural, acetaldehyde, glyoxal and crotonaldehyde or substances yielding aldehydes such as paraformaldehyde trioxymethylene and hexamethylene-tetramine. Formaldehyde is preferred. Amides specified are urea, thiourea, sulphurylamide, oxamide, malonic acid amide, succinic acid amide, biuret and di-thio-biuret as well as urea yielding substances such as amides not of themselves sufficiently water-soluble but which may be solubilized by a strong acid. The water-soluble lignin material employed is obtained by evaporation of waste liquors from sulphite or sulphate pulping processes, or from the insoluble residue in cellulose saponification processes which has been treated with caustic soda and precipitated by acidifying the solution. The pH of the impregnation and fixation steps will depend on the lignin material employed; for example, for waste sulphite liquor the soaking step must be above 3.5 whilst for lignins derived from the kraft or alkaline sulphite process the pH should be above 8.5. For the fixation step the pH should be above 8.5. For the fixation step the pH when employing lignins from sulphite liquor should be from 3.5 down to 2.5 or for alkali lignins, particularly kraft liquor, a pH down to 5.5 suffices. The pH adjustment in the soaking step may be effected by buffers such as sodium acetate, formate or phosphate or ammonium chloride, whilst the lowering of the pH in the fixation step is accomplished by acidifying preferably with hydrochloric acid but optionally with acetic acid, alums, sodium bisulphite, sodium bisulphate, aluminium sulphate, ammonium sulphate, ammonium chloride, ammonium nitrate, sodium hydrosulphite, zinc chloride, aluminium chloride, lactic acid, oxalic acid, phosphoric acid, sulphuric acid or nitric acid. The amount of active tanning ingredients may range from 5 to 100 per cent by weight of solids based on the hides treated. Suitable proportions for the active ingredients are:-watersoluble lignin derivatives 40 to 60 per cent, amide 20 to 40 per cent and aldehyde 17 to 30 per cent. According to a typical example pickled side stock was soaked overnight in a pH adjusting solution containing thiosulphate, sodium chloride, bicarbonate and formaldehyde and then drummed in a tanning solution containing sodium chloride, thiosulphate, urea, sulphite waste liquor solids, formaldehyde and water. After drumming for eighteen hours the solution was acidified with hydrochloric acid down to a pH of 1.7.

Abstract: 1,007,427. Vibration apparatus. ROWNSON CONVEYORS Ltd. May 13, 1964 [May 17, 1963], No. 19751/63. Heading B8A. [Also in Divisions B2 and F1] A vibrating conveyer or screen 6 derives it<SP>s</SP> drive from shafts 15 and 16 which are respectively connected by eccentric 13 and rod 1, and by eccentric 14 and rod 2 to link 3 pivoted at 4 to conveyer 6. Shaft 15 is driven and is connected to shaft 16 by chain 17 so that when the two eccentrics are driven in phase the conveyer 6 is vibrated. The amplitude of vibration is varied by varying the phase difference between the two eccentrics, and this is effected by passing chain 17 round sprockets 21 and 22, the sprockets being mounted on link 26 pivoted at 27 and operated by a handle 28 (not shown) secured to the shaft 27. A displacement of handle 28 causes link 26 to reposition the two sprockets 21 and 23, which repositioning causes a movement of chain 17 and a rotation of shaft 16 relative to shaft 15. In this way the amplitude of vibration of the conveyer may be varied during running. The conveyer 6 shown is provided with a counterweight 29 which likewise is driven from shafts 15 and 16 through respective eccentric 34 and shaft 32, and eccentric 35 and shaft 33, the rods being connected to link 31 pivotally mounted upon said counterweight 29.

Filed: 1926-08-13
Abstract: 277,158. General Electric Co., Ltd., Kinnes, A., and Hunt, M. S. H. Aug. 13, 1926. Electromagnetic switches; sparking, preventing.-In the manufacture of switches the contacts of which are enclosed in a highly evacuated envelope, the faces of the contacts are heated while the envelope is being evacuated, thus removing occluded gases. The heating is preferably effected by repeatedly breaking a circuit at the contacts. The Figure shows the way in which this may be done for an electromagnetic switch 1 of the kind described in Specification 271,235. The switch 1 together with auxiliary switches 2, 7 may be closed by energizing coils 8, 9, 10 respectively. A motor 13 drives a slip ring 14 and segments 15, 16 which lead the current from a negative D.C. source to coils 10, 9 respectively, the arrangement being such that the circuit to coil 9 is always broken just after the circuit to coil 10. The energization of coil 10 closes switch 7 and through it a circuit to coil 8 whereby switch 1 is closed, so that at every revolution of the motor switch 1 opens just before switch 2. A heavy current, e.g. 100 per cent overload is passed through the switch 1 first in one direction and then in the other, and should this not open, the circuit through it is at once broken by switch 2. The Provisional Specification states that the heating of the contacts may be effected by electric bombardment.

Abstract: 478,709. Cow-milkers. GASCOIGNE, G. H., and KNOX, J. R. July 21, 1936, No. 20221. [Class 84] [Also in Group XXIX] Liquid is discharged from an automatic milking system through a chamber 2, which is under continuously maintained reduced pres. sure and a supplementary chamber 8 which is counterbalanced and rockably mounted on a shaft or trunnion 7 which serves as a valve to control connections of the supplementary chamber 8 to the main chamber 2 and to reduced pressure by the rocking thereof, whereby the chamber 8 fills with liquid, overbalances, discharges automatically and then returns and refills. As shown, the milk passes through pipe 1 into collecting chamber 2 which has a vacuum connection 3. The milk passes from chamber 2 through a pipe 9 to supplementary chamber 8 which has a sleeve 13 bearing on shaft 7. The chamber 8 is counter-balanced by a weighted arm 14 mounted on a pin 14x so that when a certain amount of milk has collected therein it rocks to a downwardly inclined position, and breaks the connection to milk supply pipe 9 through a passage 13a, Figs. 2, 5, in sleeve 13 and a lateral port 7b, with which this passage co-operates, and a hollow axial portion 7a in shaft 7, and to vacuum through a passage 13b, Fig. 6, in sleeve 13 and a lateral port 7d and an axial portion 7c in shaft 7 and a suction pipe 15 connected to the reduced pressure space above the milk in chamber 2. A groove 16 on shaft 7 then registers with passage 13b to connect the chamber 8 to atmosphere and a hinged flap 11 closing the other end thereof can then open to permit the milk to be discharged into a chamber 10. The shaft 7 is supported at the ends by straps 5, 6 and has one end 7x polygon-shaped, so that after removal the shaft can only be replaced in correct position. In modified forms, the sleeve 13 may encircle the shaft 7 or the shaft 7 may be a hollow plug rocking with chamber 8' and embraced by a stationary sleeve. The Provisional Specification describes a modification in which the supplementary chamber rocks or oscillates against a spring.
