Title: Improvements in mechanism for delivering or stacking printed products in counted batches or bunches
IPC: B65H33/10
Filed: 1926-05-27
Abstract: 269,352. Hoe & Co., Ltd., R., (Hoe & Co., Inc., R.). May 27, 1926. Delivery apparatus.-In a machine for delivering thin printed products in counted batches of the kind in which stops are intermittently placed in the path of a product so as to cause it to project beyond the other products of a stack, the stops are carried by an oscillating shaft which is operated by a lever controlled by ratchet mechanism arranged to cause the stops to be raised after a variable predetermined number of products have been delivered and the projected product retains its position owing to frictional engagement of the product with the sides of the stacking-device. As shown, collected products P delivered by rolls 1 are stacked vertically in a box 5 by a reciprocating pusher 9 operated from an oscillating shaft 14, the products being stacked successively on opposite sides of the stacker. They are guided by vertical guides 6 below which are arranged stops 8 carried by oscillating arms 8<1> on a shaft 10. The stops 8 are normally out of the path of the printed product, but are raised when it is desired to cause a product P<1> to project beyond the other products in the stack, so as to separate them into counted batches. The raising of the stops 8 is effected by a camoperated oscillating lever 11 freely mounted on the shaft 10 on which the stops 8 are mounted. A pawl 20 on the lever 11 operates a ratchet wheel 25 freely mounted on the shaft 10, and after the required number of products have been stacked, a deep notch in the ratchet wheel 25 permits the pawl 20 to engage a ratchet face 22 on a lever arm 21 fixed to shaft 10, and the lever arm is moved against the action of a spring- controlled arm 24 to raise the'stop 8. A spring- pressed pawl 30 engages a ratchet face 23 on the arm 21 to hold the stops raised and this pawl 30 is released by a pin on the ratchet 25 before the next product is delivered. To vary the number of products the ratchet 25 may be arranged in conjunction with a second ratchet operated once for every complete rotation of the ratchet 25. The stops 8 in this case are raised only when deep notches in both ratchets are in alignment.

The tape is driven by a capstan 10, having a 3600 r.p.m. bipolar synchronous motor, and one or more pinch rollers 11, 13 and is guided by fixed posts 7, 8, 9, a crescent-shaped guide 12 and buffering means comprising a fixed post 19 and wall 18. The guide 12 has a flange 14 at its lower edge and a notch 15 intermediate its ends. A film of air is formed between guide 12 and the tape 1. A video record/playback head 16 opposite guide 12 is adjustable transverse to the tape 1 for track-changing. Recording and playback may be magnetic or by using grooved tracks and a piezoelectric transducer, or by using a transparent tape with the signals recorded in bright and dark regions. A 100 meter long half-inch wide tape with 180 tracks at 60 microns pitch can give a 30 minute video programme. The longest tape useable with the apparatus is said to be 300 meters. The backing of a magnetic tape may be graphite coated.

Abstract: 1,215504. Sawing. A. STOLZER. 21 March, 1968 [22 March, 1967], No. 13827/68. Heading B5L. A hack-saw machine comprises a saw blade 2 mounted in an oblique position to the direction of movement of the saw bow 1 and its guide means during its cutting stroke, and an automatic hydraulic control mechanism for pivoting the saw bow so as to lift the blade off the workpiece at the end of the cutting stroke, for lowering it upon the workpiece at the end of the return stroke, and for producing the desired cutting pressure of the saw blade, a torque acting upon the guide means of the saw bow tending to lift the blade at all times off the workpiece and an hydraulic cylinder 12 pivotally connected to the guide means exerts a force thereon in the direction opposite to that of the torque, and the hydraulic cylinder is connected to a control chamber 17 in which a piston 18 is displaceable by a control element 19 connected to and actuated by the driving means 20 of the saw bow so as to vary the volume of the control chamber. The saw bow 1 and guide means 3 therefore are mounted on a pivot 5 on the machine frame 6, the centre of gravity of the bow and guide means acting in the direction 14 to lift the block from the workpiece 9. The hydraulic cylinder acts in the opposite direction to the arrow 14. The cylinder 12 is connected by a conduit to the control chamber 17, the piston 18 of which is movable by a cam 19 on a shaft 20 which effects the reciprocation of the saw bow 1. A second cam 21 on shaft 20 engages a follower on a lever 22 which is mounted on a pivot 23 and engages a pair of levers 24, 25 on pivots 27, 28. Lever 24 actuates a feed pump 37, 38 connected by one-way valves 50, 52 to a tank 51 and the control chamber 17 and cylinder 12. Lever 25 engages an intermediate lever 39 which in turn engages a differential valve 41 which is mounted on a slide member 44 adjustable by a rack-and-pinion 45, 46 and has a plunger 42 engaging a stationary cam 43. The pivots 27, 28 are mounted on a slide member 26 movable in the direction of the arrows 36 by an arm 29 which is mounted on a pivot 30 on the guide means 3 and is integral with a lever 31 having a follower 32 engaging a cam 33 on the frame 6. In operation, the reciprocation of piston 18 in control chamber 17 lifts and lowers the saw blade in time with reciprocation of the saw blade and controls the pressure applied by the blade 4 to the workpiece. During the return stroke, the feed pump 37, 38 is actuated by cam 21 to pump a predetermined amount of fluid into cylinder 12 so that at the start of each cutting stroke, the blade is lowered a predetermined amount. The feed pump may also be actuated by the rocking of lever 29 reciprocating slide member 26, the lever being rocked by cam 33 engaging follower 32. Different cams 33 according to the crosssection of the workpiece may be provided to vary the feed. The differential valve 41 is adjustable to control the pressure with which the saw blade engages the workpiece.

Title: An improved manufacture of secondary alcohols from olefins
IPC: C07C29/06
Filed: 1937-05-20
Abstract: <PICT:0499398/IV/1> Secondary alcohols are made by treating a gaseous or liquid olefine with aqueous sulphuric acid of 1-84 per cent, removing the solution to another vessel, and, without adding water, distilling off the alcohol, using heat or live steam and then adjusting the acid to its original value by adding water if the distillation was effected without steam.  The partial pressure of the olefine may be 2-200 lb.  The olefine is passed into an absorption tower 1 containing the sulphuric acid, by a pipe 3 at a partial pressure of at least 2 lb.  Oil layers may be maintained on the surface of the aqueous acid in the tower 1.  The acid is admitted by a pipe 6 and flows downwardly.  It then passes to a stripping-tower 8.  The tower 1 may be maintained at 30-130 DEG  C. and the tower 8 is heated by a coil 10 or by live steam from a pipe 11.  Alcohol and some ether pass by a pipe 17 to a fractionating tower 18 and the ether separated is returned to the absorption tower 1.  When live steam is not employed for the distillation, water is added at the pipe 6 to restore the original concentration of the acid.  The invention is described with reference to the production of isopropyl alcohol.  Specifications 408,224, 428,792, and 499,490 are referred to.  The Specification as open to inspection under Sect. 91 is not limited to the production of secondary alcohols or to the use of aqueous sulphuric acid.  Other catalysts mentioned are phosphoric, hydrochloric and acetic acids and salts such as zinc and aluminium chlorides.  The process is not limited to the use of two separate chambers.  This subject-matter does not appear in the Specification as accepted.
