IPC: B65H7/12
Filed: 1928-08-08
Abstract: 310,253. Miehle Printing Press & Manufacturing Co. June 15, 1928, [Convention date]. Tripping-arrangements.-In connection with sheet-feeding devices for printing and like presses, such as that described in Specification 310,257, in which sheets are taken by a transfer device 10 and fed to the impression cylinder of the press, the operation of the transfer device 10 is stopped, and preferably the machine also, if two or more sheets are passed at one time towards the registering stop 15 on the transfer device. Normally a sheet is passed by a sheet forwarding and side-registering device comprising rollers 12 and balls 13 over an adjustable plate 17, which can be set in accordance with the thickness of the sheet, so as to allow a single sheet to pass readily under the curved surface 23 of the transfer device 10 and so to cover air apertures 16 arranged near the stop 15. If, however, two sheets stick together, the surface 23 prevents them from reaching the apertures 16 and the action of the transfer device is checked by automatic means of known kind which are brought into action owing to the apertures 16 remaining unsealed. The front of the plate 17 is formed with notches 32 adjacent to the apertures 16, so as to prevent the apertures being closed by the plate when set for dealing with thin sheets. The plate 17 is mounted on a shaft 18 which is controlled by a cam 21 acting on a roller 20 on an arm 19 on shaft 18. The cam 21 can be set to the required position by means of a freely mounted disc 25, Fig. 2, formed with a series of apertures for receiving a screw 31 which is screwed into a fixed aperture in the machine frame 30. The cam shaft 24 is detachably connected to the disc 25, and after the disc is set, the cam-shaft is connected by a plunger 26 to the disc.

Patent GB-991018-A (GB)
Title: New phosphoric acid esters and pharamaceutical compositions containing them
Inventor: ROSENMUND HANS
IPC: C07F9/12
Filed: 1961-06-26
Abstract: The invention comprises compounds of the general formula <FORM:0991018/C2/1> wherein R is a straight chain saturated hydrocarbon radical having a chain of 4 to 10 carbon atoms and A is a hydrogen atom or a salt-forming cation with the proviso that not all the symbols A need be alike.  They may be obtained by hydrolysing, generally with water, an acid tetrahalide of the general formula <FORM:0991018/C2/2> and, when a salt is to be produced, treating the resulting acid ester with an organic or inorganic base.  The cation A may suitably be an alkali metal ion or an organic base ion, e.g. of ethanolamine, triethanolamine or colamine or other physiologically acceptable base.  The alkali metal salts may be obtained by dissolving the corresponding free acid ester in ethanol and mixing with a solution of sodium or potassium ethanolate, the mono-, di-, tri- or tetra-alkali metal salt being obtained depending on the amount of alkali metal present.  In order to obtain the tetra-alkali metal salt, a tertiary base, e.g. pyridine should be present. Examples are given for the production of p,p1-diphenyl - 1,4 - n - butane - diorthophosphoric acid monoester and p,p1-dihydroxy-1,6-diphenyl - n - hexane, diorthophosphoric acid and its tetrasodium, tetraethanolamine, tetracolamine and tetra-triethanolamine salts.  The products of Formula I may be purified via their alkaline earth metal, lead, or copper salts.  The compounds of Formula II may be obtained by reacting a compound of the formula <FORM:0991018/C2/3> with a phosphorus oxyhalide, e.g. oxychloride r oxybromide, if desired in the presence of tertiary organic base, e.g. pyridine or quinoline.  The products of Formula I are useful for treating prostate diseases and may be used in admixture with an inert pharmaceutically acceptable carrier.

Abstract: 677,790. Transferring loads between vehicles and platforms. WILLIAMS, W. P. (Kappen, J. W.). Sept. 7, 1949. No. 23226/49. Class 78 (iv). Apparatus for the warehouse loading of merchandise onto transport vans consists of a frame mounted on the loading platform and provided with rollerways and means for positioning a van against the edge of the platform such that the rollerways on the frame are aligned with rollerways in the van, so that pallets supporting the merchandise may be arranged on the frame and pushed into the van simultaneously without disturbing the arrangement. A frame 10, Fig. 2. is secured to the platform and consists of side members 15, 16 joined bv cross bars 17, each side member being provided with rollerways 21, 23. Pallets 24 are each loaded with goods for one destination only and are raised by a lifting truck and deposited on the rollerways in the reverse order of destination ; guides 57 on the side members assisting the positioning of the pallets on entering the frame. The frame 10 is secured to the platform about its own length behind the platform edge and when a van arrives a portable frame 11 mounted on castors is wheeled into line with frame 10, whereupon its remote end is at the platform edge. Frame 11 is also provided with rollerways aligned with the rollerways 21, 23 and the interior of the van 35 is provided with further rollerways which are aligned with the rollerways in frame 11 when the van is correctly positioned. The lift truck can thus be used to push the pallets as a whole along the rollerways into the van. The means for correctly positioning the van with respect to the platform 12, Figs. 4 and 5, consists in providing a pair of runways 38 along which runs a carriage consisting of an angle iron 41 supported by wheels 42 and pairs of wheeled legs 43, 44. The runways 38 are of a wide U-section so that some side movement of the angle iron 41 can take place. When van 35 backs towards the platform the rear wheels are raised by a ramp 52. Angle iron 41, which will have run to the outer ends of runways 38 by gravity, is then manually engaged with a depending portion 49 on the van such that the sides of the portion 49 are rigidly located between upstanding lugs 51 on iron 41. As the van backs further the weight of the van is gradually transferred to the angle iron 41 as this rises along runways 38. On approaching the rearward position against the platform the van's rear wheels are transferred to a plate 53 supported on rollers 54 allowing lateral movement. During the final rearward movement a peg 48 on the angle iron 41 is engaged between a pair of fixed prongs 46 while diagonal plates 45<SP>1</SP> on the ends of the angle iron 41 engage diagonal fixed plates 45 so as to centre the angle iron 41 and hence the rear of the vehicle, thus aligning the ends of the rollerways in the van with the rollerways in frame 11.
