Title: Improvements in means for holding and facilitating the registering of printing blocks
IPC: B41B1/00
Filed: 1931-11-16
Abstract: 384,061. Printing-surfaces. VERSTAGE, S. A., High Street, Odiham, Hampshire. Nov. 16, 1931, No. 31763. [Class 100 (ii).] In means for mounting and registering printing-blocks or plates clips adapted to engage over or through the edges of the block or plate are adjustably fastened by screws passing through slots in them to the mounting board or quad. In Fig. 2, the clips 3 are shown with a horizontal limb 4 adapted to engage the edge of the plate and a slotted limb 6 through which passes a screw 8 into the quad 9. The clip may simply have one end turned up at an angle to engage the bevelled edge of a plate, or may be a flat piece of metal with a bevelled undercut end and slot. For registering in multicolour printing, the original 16, Fig. 4, is first photographed on the mounting board 15 with registration marks such as chevrons 20 or circles 14 placed near it. Holes are drilled in the resultant plate to correspond with the circles 14 and wedge-shaped recesses 21, Fig. 5, are cut to correspond to the chevrons 20. Then if a clip 22 with a pointed end is used to engage the recesses 21, or a clip bearing a short vertical pin to engage the holes, different plates may be dropped upon the mounting board in exact register and locked into position by clips 3.

Patent GB-837563-A (GB)
Title: Improvements in or relating to pallet loading apparatus
IPC: B65G57/00
Filed: 1956-10-19
Abstract: 837,563. Stacking-machines. GREER CO., J. W. Oct. 19, 1956 [Oct. 20, 1955], No. 31893/56. Class 94(1). The invention relates to a pallet loading device generally similar to that described in Specification 781,736 but differing mainly in that the loading carriage has beneath it a sensing means which contacts the pallet or a previously deposited tier of articles thereon and operates switch means to indicate unloading of the carriage. As in the above Specification, the apparatus comprises a framework 100 having vertically moveable within it an elevator 104, and a carriage 154 movable transversely to and suspended from the elevator. When the carriage is loaded at position A, it is traversed to a position B above the pallet and the elevator is lowered until a sensing plate 270 contacts the pallet or previously loaded articles at position C as shown. The plate 270 extends across substantially the whole of the underside of the carriage and may operate any of four switches 274. When the plate is moved by contact with an object, solenoids 284 raise it clear of the object, a stripper arm 200 swings down to retain the articles supported by the carriage, and a stop 238 to the rear of the carriage is lowered. The carriage then moves transversely to position D, the articles being stripped from it. The elevator returns it to A for reloading. The apparatus is fully automatic, an electrical control system, Fig. 10 (not shown), being described.

Title: Tire mounting and demounting apparatus
IPC: B60C25/132
Filed: 1964-08-05
Abstract: 1,082,112. Tyre and rim manipulating apparatus. COATS CO. Inc. Aug. 5, 1964 [Aug. 6, 1963], No. 31895/64. Heading B7C. In tyre mounting and demounting apparatus a single power source simultaneously operates diametrically-opposite upper and lower bead breakers 22, 21 respectively and rotates a wheel-rim locating shaft 16 carrying an auxiliary toul not shown). A pin 19 engages a bolt hole in the rim to prevent rotation thereof. In operation, a shoe 73 (Fig. 1) on an arm 72 (Fig. 3) is placed on the upper tyre bead and a pedal 34 is depressed to expand a bellows 26 thereby causing a bushing 46 of crank-lever 45, 36 to engage in a bearing surface 75 or 76 on the arm 72 (depending on rim size) so as to depress the shoe 73 and thereby break the upper bead. Simultaneously lower shoes 77, 77a are urged against the lower sidewall and bead respectively to break the lower bead. Also at the same time a pulley 44 is moved to the right (as viewed in Fig. 3) by an arm 43 fixed to the crank-lever, thereby rotating a pulley 63 on which the shaft 16 is fixed. Springs 56 return the crank-lever to its initial position causing rotation of the shaft in the opposite direction. A relatively-small diameter rim strokes a dog 82 which prevents the stress 77, 77a from travelling beyond the rim mid-plane.

Title: Improvements relating to the manufacture of carburetted water gas
IPC: C10J1/213
Filed: 1948-12-09
Abstract: 654,575. Carburetted water gas. GAS MACHINERY CO. Dec. 9, 1948, No. 31925. Convention date, July 22. [Class 55(i)] In a blow and run carburetted water gas process, which enables low grade solid fuel and unrefined oil to be used, the blast air is directed to the central portion only of the bottom of the fuel bed, secondary air being supplied to the top of the bed over which oil is sprayed during the run. The drawing shows the invention applied to a water gas set consisting of a generator 11, a carburetter 12 and a superheater 13. The generator contains a fuel bed 23, e.g. of soft coal, supported on a grate 36 which is disposed centrally of the generator and occupies from 30 to 60 per cent of the internal cross sectional area of the latter, depending on the type of fuel to be gasified. In operation, blast air from a pipe 22 is first admitted under the grate, the restricted opening thereof causing even distribution of heat in bed 23. Secondary air is simultaneously admitted through pipes 26, which direct the air radially or tangentially over the top of the bed to burn blast gas in contact therewith. The run comprises an up run, steam being admitted at 30 and oil, e.g. Bunker C oil, being sprayed on to the top of the fuel bed from a jet 27 and, if desired, into the carburetter from a jet 28, and a back run, steam being admitted at 29. A two-shell set with no carburetter may be used, in which case the generator is made taller to include an upper zone which functions as a carburetter.

Abstract: The invention comprises compounds of the formula <FORM:1066254/C2/1> wherein Y is a 1-aziridinyl, 1-azetindinyl, 1pyrrolidinyl, 1-piperidino, 1-hexahydro-azepinyl, heptamethylenimino, octamethylenimino, morpholino or thiomorpholino group, and Z is -(CH2)n-, where n is 1-3, or -CH2-N(CH3)-and the acid addition salts, alkyl quaternary ammonium salts, N-oxide and acid addition salt of N-oxide thereof.  The compounds are made by reacting at 0-100 DEG  C. chloromethane sulphonyl chloride with <FORM:1066254/C2/2> preferably in an inert solvent in the presence of an acid-binding agent at 20-50 DEG  C.  The N-oxides can be made by oxidation with peroxides. The free bases can be converted to the acid addition salts or quaternary ammonium salts by conventional methods.  The free base or its N-oxide also form salts with penicillins, which salts provide a means of isolation and purification of penicillins, particularly benzyl penicillin.  These salts can be made by neutralizing the free base with the free acid form of the penicillin or by metathesis using an acid addition salt of the free base.
