Title: Improvements in core peeling devices for foundries
IPC: B22C9/18
Filed: 1926-10-26
Abstract: 260,594. Brune, R. Oct. 29, 1925, [Convention date]. Core-making.-Cores are made by forcing a previously-rammed column of sand through a trimming-die which is of a contour corresponding to that desired. The sand is rammed into a box 22 secured, as by a bayonet joint, to the machine base 1, the trimming-die 17 being similarly secured above the upper end of the box. The sand is forced from the box and through the die by a plunger 15 faced with wood at 16 and operated by rack and pinion, driven by a chain 9 from the hand crank 6. A tube 32 accommodates the rack bar in its lower position. Surplus sand falls into a container 3 which is recessed at the front side to suit the body of the operator. Shoulders or grooves may be formed by a cutter 31 carried in a handled split-ring mounted on a flange on the die-holder.

Abstract: 535.188. Centrifugal machines. BAIRD & TATLOCK (LONDON), Ltd., and FUCHS, H. J. Sept. 2,9, 1939, No. 26894 [Class 23] In a suspended bucket centrifuge a number of working bucket angles for a given speed are obtained by employing a pair of symmetrically opposed bucket carriers 7 supported in bearings 5 in forked ends 3 on the crosshead 2. Each carrier 7 has a hole 8 arranged at the pivoting axis and another 9 spaced outwardly from it. When the buckets 4 are in the holes 8 they will assume a position of practically 90 degrees to the centrifuge axis during working, and less than this if they are in the holes 9; if buckets are placed in holes 8, 9 a third angle of inclination is assumed. The buckets 4 may rest on rings 10 in the carriers, and by using rings of different lengths further variations in the angle of inclination during working may be obtained. Specification 527,712 is referred to.

Abstract: 272,093. Valor Co., Ltd., and Wood, A. J. Oct. 29, 1926. Plain plug stoppers for metal and other containers for oil and other liquids comprise a hollow tubular member a closed at its upper end and of smaller diameter than the neck d of the container to adapt it to be inserted therein to engage an inwardly projecting rib e located at some distance from the mouth of the container, the arrangement avoiding compression of the air in the container when the closure is applied. The rib, the distance of which from the mouth of the neck is less than the length of the stopper, is formed by rolling or pressing in the neck an exterior curved or semi-circular groove. Secured to the closure member is an outer tublar member k of greater diameter than the neck, also closed at its top, a resilient washer j being disposed in the recess between the tubular members where it is engaged by a roller bead l formed on the upper edge of the neck of the container. The tubular members are formed from sheet metal by spinning or pressing, the upper end of the wall of the outer member being flared outwardly to accommodate the washer and afford a finger grip.

Patent GB-616730-A (GB)
Title: Improvements in the production of hard pitch and oils from medium soft coal tar pitch
IPC: C10C1/16
Filed: 1946-09-10
Abstract: <PICT:0616730/III/1> Medium soft pitch is converted into hard pitch with simultaneous recovery of oils by passing the soft pitch in the molten state, at a temperature not exceeding 350 DEG  C., through a cascade tower maintained under reduced pressure, from the bottom of which partially stripped pitch is withdrawn and re-circulated to the tower, preferably through a pipe-still; hard pitch is withdrawn from another section of the tower and the oil vapours evolved from the top are passed to a condenser.  Soft pitch of melting point 80 DEG  to 85 DEG  C. is introduced at a temperature between 300 DEG  and 350 DEG C., through pipe 1 into cascade tower 2 which is maintained at a pressure of 50 mm. by steam jet pump 3.  The pitch cascades down the tower, with partial vaporization of the oils therein, to reservoir 4 from which it is withdrawn and pumped, through pipe-still 6 and line 7, to the upper section of tower 2.  The pitch then cascades down to reservoir 8, evolving the remainder of the oil, from which it is removed by a barometric leg to seal pot 9.  Superheated steam or air, to assist distillation, may be introduced, through pipes 10, into reservoirs 4 and 8; and also into the pipe-still.  The vapours from the tower are passed to contact condenser 13 where the oil is condensed by a counter-current cascade of the distillate pumped up from balance tank 141 through cooler 16.  Alternatively, another type of tar oil, such as creosote, may be used for condensing the vapours from tower 2.  Any gases leaving condenser 13 are cooled in cooler 17 and pass on to reservoir 24 which is maintained at atmospheric pressure.  A portion of these gases may be recycled to the cascade tower, the amount being controlled by controller 21.  The production of hard pitch from the soft pitch derived from crude coal tar acids is referred to.

Title: Glass tempering apparatus
IPC: C03B27/02
Filed: 1960-08-08
Abstract: 893,949. Glass tempering apparatus. WARTENBERG, E. W. Aug. 8, 1960 [Aug. 18, 1959], No. 27378/60. Class 56. In apparatus for tempering glass by quenching in a boiling liquid within a heated container, the container is of elongated shape and is provided with heat insulated walls and a cooled cover. As shown in Figs. 1 and 2, the container is made with double walls of sheet steel, filled in with insulating material 40, such as glass wool. The liquid, which is preferably carbon tetrachloride less than half fills the container up to the level 11 and is heated by elements 2 in the double bottom. A screening plate 3 of sheet aluminium is supported above the bottom by legs 1 and a box 5 of wire on the plate 3 is used for collecting broken glass. A pair of supports 6, 7 with lateral buffers 8 of graphite prevent the glass plates 9, 10 from swinging under the action of the gas envelope which surrounds them from the boiling liquid. The vaporized liquid rising from the level 11 is cooled in its upward passage and condensed thereby and returned to the mass, where it is reheated by additional heating elements 12 and 13. The cooling of the vapour is assisted by the cooled cover, which, as shown, comprises a pair of cooling boxes 20, 21 mounted by rollers 22 on rails 23, 24 for simultaneous movement by means of links 29 and rack 25 and pinion 26 which may be driven by a hand crank 32 or by a motor. Cooling water is circulated through the boxes 20, 21. The container 1 is also provided with a pair of thermostats 14, 15, observation windows 16, 17 an outlet valve 37 and ducts 18, 19 above the level 11 for a protective gas such as CO 2  or N 2  for use when the liquid used is combustible. As shown in Fig. 5, the plate 3 is replaced by a heater element 54 mounted on supports 56, 57 through which cables 60, 61 may be passed and a pair of adjustably mounted heating plates 51, 52 extend parallel to glass plates 49 and replace the heating elements 12, 13. The adjustment of the plates allows different liquids to be used and can vary the degree of temper for a particular liquid. In a further embodiment, not shown, the plates 51, 52 are used with the plate 3 and box 5. In a suggested embodiment, the cover may be a single stationary cooling box provided with a slot.

Title: Process for the production of halohydrins
IPC: C07C29/66
Filed: 1955-09-29
Abstract: A halohydrin is prepared by reacting an olefine which is liquid under the reaction conditions with halogen or a hypohalous acid in an aqueous medium, wherein the aqueous medium used is a solution of an alkaline earth and/or alkali metal halide which solution is practically saturated with the corresponding halohydrin.  The aqueous layer obtained after separating the chlorination product may be recycled to the halogenation stage and may have a density which is higher than that of the crude chlorination product.  The aqueous medium may be neutralized with a basic alkaline earth or alkali metal compound before it is recycled to the chlorination stage.  Part of the aqueous medium withdrawn from the cycle may be replaced by water before the neutralized aqueous medium is recycled so as to keep the composition and density of the aqueous medium constant in the chlorination stage.  Suitable olefines are styrene, cyclohexene and 1,1-di-phenylethylene.  In the examples styrenechlorohydrin and styrene dichloride are obtained from styrene, 1,1 - diphenyl - 1 - oxy - 2 - chloro-ethane is obtained from 1,1-diphenylethylene, and cyclohexenechlorohydrin is obtained from cyclohexene.
