Title: Improvements relating to conveyors
Inventor: ROOKE SYDNEY WILLIAM
IPC: B07C3/08
Filed: 1964-04-14
Abstract: 1,098,274. Endless conveyers. SOVEX Ltd. July 12, 1965 [April 14, 1964; Dec. 2, 1964], Nos. 29455/65 and 49022/64. Heading B8A. Documents are conveyed on carrier tray 57 of an endless chain elevator, and at a discharge station may be discharged to a conveyer 65a if they are contained in a container 21, otherwise they are discharged to a conveyer 65b. In a modification (Fig. 1, not shown), documents not in a container are discharged via a shoot (64) to a box (65). Containers are suspended by side ribs (26) which engage rails (62) leading to a conveyer 63. The carrier tray 57 is shown in its discharging position. In its normal conveying position its load-carrying surface is horizontal, a pin 53 being latched in a member 48 which runs in rails 50. The tray 57 may carry destination selectors which determine at which station the tray is to be discharged. A correspondence between the setting of the selector and mechanism at a selected station causes release of the latch at 53 thus permitting the member 53 to leave the member 48 and follow the contour of guide rails 55a (if a container is to be discharged) or the guide rails 55b (if documents on their own are to be discharged. Portions 55d of the rails 55b lift to permit the member 53 to pass the rails 55b when necessary. In a modification, if at a station at which a discharge has been signalled, a container is not sensed as being present on the carrier tray, release of the latch is made subject to a mechanical and/or electrical time delay. Containers or documents are fed to the downward moving side of the elevator through an opening (58) (Fig. 2, not shown). A container engaging the sill 60 of this opening would operate a switch to stop the elevator. The same result would obtain by the presence of a container or document for an undue time in the opening 58. The containers may also carry destination selectors which may operate a selected carrier tray of the present elevator and may also control the selection of conveyers in a system as described in the parent Specification.
Patent GB-902724-A (GB)
Title: Separation of aromatic isomers
Inventor: FLECK RAYMOND NICHOLAS
IPC: C07C51/487
Filed: 1960-02-15
Abstract: A process for effecting at least a partial resolution of a mixture of isomeric dihalobenzenes, cresols, monohalotoluenes or toluidines comprises contacting the mixture in fluid form with a solid granular absorbent consisting essentially of a zeolitic crystalline, partially dehydrated, metallo alumino silicate having pores of substantially uniform diameter between 7 and 13   and separating the fluid phase from the solid phase.  The adsorbent used is a zeolite X "molecular sieve" of the type described in Specification 777,233 and U.S.A. Specification 2,882,244.  The adsorbed component of the mixture may be desorbed by contacting the solid phase with a displacement exchange fluid which is adsorbed on the zeolite and from which the desorbed component may be readily separated.  The adsorbent may be used in 1 or more static beds, when adsorption and desorption may take place simultaneously in different beds in the set, or as a moving compact bed.  The process may be worked continuously by (1) contacting the mixture with a lean adsorbent upon which is adsorbed the displacement exchange fluid to obtain a rich adsorbent and a raffinate comprising unadsorbed components and displacement exchange fluid, (2) contacting the rich adsorbent with the exchange fluid to give a lean adsorbent and an extract comprising adsorbed components and exchange fluid, (3) recycling the lean adsorbent to (1), (4) separating exchange fluid from the raffinate and extract and (5) recycling the separated exchange fluid to (2).  The process is preferably carried out in the vapour phase at 100-700 DEG F. and 0-100 p.s.i.g.  In the examples the following pairs of isomers are partially separated: o- and m- and m- and p-bromotoluene, o- and p-chlorotoluene, p- and m- and o- and m-dichlorobenzene, (exchange fluid, chlorobenzene); o- and p- and m- and o-toluidine, (exchange fluid, aniline); and p- and m- and o- and m-cresol, (exchange fluid, phenol).  Reference has been directed by the Comptroller to Specification 828,777.

Title: Improvements in or relating to rag engines or the like
IPC: D21D1/14
Filed: 1930-10-02
Abstract: 356,520. Paper pulp beaters. HERY, E., 63, Avenue des Champs Elysees, Paris. Oct. 2, 1930, No. 29530. Convention date, Oct. 4, 1929. [Class 96.] In a beating-engine for triturating, dividing, shortening, hydrating, shredding or refining fibres for making paper or cardboard, the roll 1, bedplate 5, and circulating channel are formed so that the pulp approaches the roll in a radial direction over a small arc, and after passing upwardly between the roll and the bedplate and being thrown off in a direction tangential to the roll where it leaves the bedplate surmounts a jump 13 and falls into the return part of the channel without further contact with the roll, thereby minimizing useless churning of the pulp and circulating it by its kinetic energy of leaving the beating surfaces. The pulp may be projected over the bedplate or over the roll, in either case the direction of flow to the pulp being modified at the region where it meets the roll. The bottom of the vat is raised towards the roll to reduce the arc AB to the minimum necessary to charge the spaces between the roll blades 2 with pulp. The plate 5 in a support pivoted at 6 is pressed by a weight 7 movable along a lever 8 pivoted at 9 and may have a spring connection 11. When the weight 7 is moved to the end of the lever nearer the roll it forces the plate from the roll to a position limited by a stop 10. The invention is applicable to beating-engines having several rolls. Specification 138,868, [Class 96, Paper &c.], is referred to.

Title: Hydraulic presses or shears having several press cylinders
Inventor: NIEDERREITHER JOHANN
IPC: B30B15/24
Filed: 1956-10-01
Abstract: 850,584. Hydraulic presses. MENGELE, K., and MENGELE, A., [trading as MENGELE & SOHNE MASCHINENFABRIK UND EISENGIESSEREI, K.]. Oct. 1, 1956, No. 29878/56. Class 69 (2). In a multicylinder hydraulic press or shears having a control valve 62, 63 for each of the two or more cylinders 92, 93 which actuate the beam 98, said control valves 62, 63 being interconnected by rack-and-pinion gear 79, 80, 81, means are provided to ensure parallel guidance of the beam 98 by compensating for dimensional alterations of the press frame due to load, such means comprising at least one member (e.g. 123, 124, 131, 132) included in the valve interconnecting gear the length of which is automatically varied in dependence on the fluid pressure in one of the press cylinders. The arrangement also compensates for tilting of the beam due to asymmetric positioning of a member such as 120 being pressed thereby. In Fig. 1, a pressure-responsive lengthening device 123, 124 and a similar shortening device 131, 132 are included in each valve-rod, together with screw means 125, 126 for initial adjustment. As shown, the rod of the righthand valve 63 has been raised, resulting also in the raising of the left-hand valve 62 through the rack gear, whereby both valves supply fluid pressure from a pump through lines 70, 71 and 90, 91 to the upper chambers of the cylinders 92, 93. When the press beam applies the load, the press frame elongates vertically, thus raising the cylinders and valve bodies 62, 63 a small distance h. To prevent such displacement causing depression of the valve slides relative to the valve bodies, pressure from the respective cylinders is fed simultaneously through lines 127, 128 to the corresponding valve-rod lengthening devices 123, 124, where it acts against calibrated diaphragm springs 130 to lengthen the rods of either valve by the same amount h as that which its own valve body has been raised, thus maintaining valve setting in spite of upward distortion of the frame. Beam tilt due to asymmetric loading is compensated by the shortening devices 131, 132 which receive pressure through lines 133, 134 from the pressure chambers 93, 92 of the opposite cylinders, such pressure acting against internal diaphragm springs 136 to shorten the valve-rod on that side of the press on which cylinder pressure is the lesser, thereby tending to close the valve at that side and preventing downward tilt of the beam. The lengthening and shortening devices 123, 124 and 131, 132, which are themselves adjustable for initial spring compression, are shown in detail in Figs. 2 and 3 (not shown) and are combined in a single device in Fig. 4 (not shown).

Abstract: 377,516. Control of D.C. motors. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A. -(Assignees of Allgemeine Elektricitõts- Ges. ; 2, Friedrich Karl-Ufer, Berlin.) Oct. 29, 1931, No. 30022. Convention date, Oct. 30, 1930. [Class 38 (iii).] Field control.-A shunt motor a for lifting gear is given a series characteristic when operating with weakened field by means of a motor m connected across the field resistance v and driving a load constituted by an eddy current brake or by a generator g supplying a resistance b. The fields fm, hm of the motor are opposed to each other whilst the field fg, which is only used during lowering, aids the field hg of the generator. As long as the resistance v is shortcircuited the set m, g is stationary. When a part or the whole of this resistance is inserted in circuit with the field fa the set operates. An increase of current through the armature a causes weakening of the effective field of the motor m which thereupon increases in speed. The increased speed of the generator g and its increased field cause an increased loading thereof so that the motor m draws an increased current from the supply through the field fa. During lowering, if the load overhauls the motor a, regeneration occurs and the field hm reverses and aids the field fm, this would cause incorrect functioning of the set m, g if the field of the generator g had not been increased by the field fg. It is advantageous to cut out the field hm during lowering.
