Title: Film sheet dispenser
IPC: G03B42/04
Filed: 1971-07-06
Abstract: 1361014 Feeding sheets PRODUCTION Inc 6 July 1971 [7 July 1970 7 Jan 1971] 17408/73 Heading B8R [Also in Division G2] A dispenser for dispensing film sheets comprises a support for a stack of such sheets, a first cam for engaging and releasing the lower edge of the foremost sheet at a first location, a second cam for engaging and releasing the lower edge of the foremost sheet at a second location, and means for operating the two cams alternately so as to successively release one sheet at a time from the stack. Fig. 1 shows a stack 20 of X-ray film sheets as described in Specification 1,361,013, the successive sheets having a notch alternately in position 28 and position 30. The stack is packed for storage in an envelope 32, Fig. 2, of an opaque black plastics material. The dispenser itself is shown in Figs. 3 and 5. The envelope containing the stack of sheets is inserted through a door 80 and its leading end 34 held by or secured to a bar 70. The free trailing end 35 of the envelope is inserted under a cutting edge at the lower end of door 80. Thus as the door is closed the end 35 is cut off. A handle 72 rotates the bar 70 which strips the envelope away from the stack of film sheets, which is left supported by a pair of bars 86, 88 (see also Fig. 4, not shown). Bars 86, 88 are flanged upwardly at their forward ends 90, and have at their rear ends a pin 103 sliding in a slot 104 in a fixed plate 105. The rear ends are also pivoted to a channel member 94 which can be moved vertically by a rack portion 98 driven by a pinion 100 on a crank 102. As the crank is turned to move member 94 downwards, the bars 86, 88 pivot from the Fig. 4 (not shown) position to the Fig. 5 position, so that they disengage from the stack of sheets, leaving them supported by a pair of cam rods 130, 132 having triangular cams 134, 136 at their forward ends. The sheets are urged forward against these cams by a pressure plate. A pair of pins 143, 144 engage mid-way up the stack of sheets to prevent it buckling. The cams engage the sheets at the notched portions 28, 30. If for example cam 134 is aligned with a notch in the top sheet, then cam 136 is bearing against an unnotched portion. As cam 136 is rotated, it comes away from engagement with the sheet. As this no longer has anything bearing against its lower edge, it jumps forward, under the action of pressure from behind, and falls through a slot 252, 253 into the cassette 56. (When cassette 56 is moved into position for receiving the sheet, pins 143, 144 are moved out of engagement with the sheets). A gear train (Fig. 6, not shown) is provided which rotates the cam rods 130, 132 alternately. The cassette itself is claimed in Specification 1,361,012.

Title: A process for the catalytic hydrogenation of carbon monoxide
Inventor: KOELBEL HERBERT
IPC: C08G61/04
Filed: 1950-07-25
Abstract: Paraffin wax is produced by the hydrogenation of carbon monoxide in the presence of an iron catalyst which is periodically recharged with an alkali metal compound by adding the same to an agent used for extracting the wax from the catalyst.  Preferably, the bulk of the wax is first removed by one or more extractions, and a final extraction then made with the extraction agent containing alkali metal compound in solution or in fine suspension such that not more than 80, and preferably less than 50, per cent precipitates in 1 hour.  Recharging may be effected at intervals of 250-700 hours. Suitable alkali metal compounds are oxides, hydroxides, carbonates, bicarbonates, phosphates, silicates and borates of sodium and potassium, and alcoholates, formates, acetates or soaps.  The extraction agent may be a heavy naphtha.  The hydrogenation may be effected at 160-300 DEG  C. and 1-50 atmospheres.  In examples, precipitated iron catalysts which may contain copper and magnesium as activators in addition to alkali metal, and kieselguhr or dolomite as support are used at 230 DEG  C. and normal pressure or 214 DEG  C. and 11 atmospheres, wax being extracted periodically with heavy naphtha, the final wash in each case containing about 50 g./l. potassium carbonate or phosphate.ALSO:Paraffin wax is produced by the hydrogenation of carbon monoxide in the presence of an iron catalyst which is periodically recharged with an alkali metal compound by adding the same to an agent used for extracting the wax from the catalyst.

Filed: 1927-07-05
Abstract: 273,771. Cousinard, A. July 5, 1926, [Convention date]. Stud-and-socket fastenings; catches, spring.- A motor car door is secured by a stud entering a conical socket in which it is engaged by pivoted catches, release being effected by a push-andpull spindle. The stud 4 is carried by a plate 1 mounted on the door. A spindle 31 passes through the door and has a shank 15 and head 29 working in the stud 4 on the inside and a handle 32 on the outside. A pair of hook-like catches 5, 6, are pivoted in the stud and their hooks 24 protrude through openings in the stud so that when the stud is forced into the socket member, a member 22 rides over the stud and is engaged by the hooks, Fig. 3. Release is effected by moving the spindle 31 axially by the handle 32 or head 29, shoulders 13, 14 on the shank 15 engaging the tails of the hook-levers and rocking them out of engagement with member 22. A sliding bolt 38 can be pushed inwards to prevent actuation. The member 22 carries a pair of rubber buffers 27. Instead of operating the spindle 31 from the inside by the head 29, a lever 47, Fig. 5, may be employed, to prevent accidental release. The lever when rocked, moves a rod 44 rocking a lever 40 on its pivot 43 and causing its finger 41 to move the spindle 31 axially. A pivoted member 49<a> permits operation in its mid position, but prevents operation when turned up or down.
