Abstract: 754,646. Sheet-delivering apparatus. FABER & SCHLEICHER AKT.-GES. Dec. 15, 1954 [Dec. 28, 1953], No. 36262/54. Class 100 (1). A sheet-stacking device in which the sheets are delivered during the exchange of the main pile 3 on to an auxiliary receiver or grate 15 introduced above the main pile, is characterized by the provision of guides 17 for guiding the leading edge of the grate 15 during its ingoing movement over the main pile in an initially downward path toward the top surface of the main pile. As shown in Fig. 2, sheets 1 are delivered by grippers 2 on chains 5 to the pile 3. Fixed upon a rockable link 11 are front stops 13 to which are pivoted suction nozzles 27. The grate 15 consists of longitudinal slats connected at their front end by a cross bar 16 which normally rests in a mould 35. When it is desired to insert the grate the cross bar 16 is slid along a branch guide 20 and held by a lever 21, controlled by a cam 25 in timed relation with the delivery grippers 2. When the cam 25 retards the lever 21 the grate 15 drops towards the top of the pile 3 and at the same time depresses rollers 26 to cause the nozzles 27 to move into a position so that they retain the leading edge of the next sheet delivered while the grate is inserted along the guide 17. A grate-operated valve 36 controls the suction to the tube 11 which communicates via bores 32, 31 with the nozzles 27. The grate is withdrawn along the branch guide 34, the front stops 13 being rocked anticlockwise on the tube 11 by the cross bar 16 to allow passage thereof. In a second embodiment (Fig. 6), only one guide is used the upper end of the stops 39 having pivotable portions 41 thereon which allow the passage of the cross-bar 16 in both directions.

Title: Extraction of diolefins from a hydrocarbon feed containing diolefins, monoolefins and saturated hydrocarbons
IPC: C07C7/10
Filed: 1960-10-24
Abstract: In the extraction of diolefins from hydrocarbon mixtures also containing olefins and paraffins of the same carbon number the diolefin is first extracted with aqueous cuprous ammonium acetate in a first stage and the diolefin recovered from the extract phase and in a second stage, part of the raffinate from the first stage is contacted with aqueous cuprous ammonium acetate to obtain a raffinate of increased paraffin to olefin ratio which is discarded and an extract phase which is mixed with the lean cuprous solution to the first stage.  The process is particularly suited to the recovery of butadiene from a butene hydrogenation process; the raffinate from the first stage not passed to the second stage is recycled to the hydrogenation.  The second stage is preferably effected in two sub-stages, lean cuprous solution being fed to the second sub-stage and the extract from that being fed to the first sub-stage and thence to the first, diolefin extraction, stage.

Title: Denatured skim milk powder mixture
IPC: A23K10/28
Filed: 1977-09-05
Abstract: The skimmed milk powder denatured with fishmeal is mixed with precipitated, spray-dried silicic acid having a BET surface area of 100 to 500 m<2>/g. Even by such a low proportion of silicic acid, which does not interfere with the energy balance of the mixture used as a feedstuff, the caking of the feedstuff caused by the high moisture content of the fishmeal in the mixture is prevented, so that this remains pourable and able to be stored in silos for months. The mining work necessary hitherto as a result of the caking is thus dispensed with.

Patent GB-374075-A (GB)
Abstract: 374,075. Time-printing apparatus. KRANSE, A. C., 227, Blackfriars Road, Bermondsey, London. Nov. 29,1930, No. 36003. [Class 100 (ii).] The time-printing wheels of a time recorder or other apparatus are advanced stepby-step by a pawl and ratchet mechanism controlled by an oscillatory member, the movements of which are employed to render the pawl operative or inoperative alternatively or in any desired sequence of strokes. In the form shown the type wheels are advanced at minute intervals by impulses transmitted from the clock at half-minute intervals. The type wheels (not shown) and minute and hour hands 1, 2 are mounted in a casing 3, Fig. 2, the intermittent drive thereto being transmitted through a shaft 18 and gearing 15, 16 from a ratchet wheel 14 and pawl 4. The pawl 4, Fig. 1, is carried by an arm 5 pivotally mounted on a bar 9 on a lever 6 having an armature 10 co-operating with an electromagnet 11. To interrupt the effective movement of the pawl 4 a pin 21 thereon is adapted to engage the arm 20 of a trip lever pivoted on a shaft 19. The trip lever is rocked to raise or lower the arm 20 by the engagement of its arm 26 with a toothed cam 25 to which is secured a ratchet wheel 23 actuated by a pawl 22 carried on the bar 9. The ratchet wheel 23 has twice as many teeth as the cam wheel 25 so that in the successive to and fro movements of the arm 5 the pawl 4 is alternative operative and inoperative. The wheel 14 is normally held against movement in either direction by a locking tooth .30 on an arm 31. The arm 31 co-operates with an extension 34 on the pawl arm 5 so as to withdraw the locking tooth when the ratchet wheel is tu be advanced, the tooth returning to locking position at the termination of the movement. During an idle movement of the pawl arm the locking tooth remains in engaged position as the arm 31 is out of reach of the extension 34. The lever 6 may be rocked manually, or held against actuation by the electromagnet by means of a handle 36. To set the hands 1, 2 or the type wheels otherwise than by operation of the handle 36, a manually operated shaft 39 is manipulated to rock a release plate 40 co-operating with an arm 41 of the trip lever and with the locking arm 31 so as to raise the arm 20 and withdraw the locking tooth 30.
