Title: Improvements relating to aircraft undercarriages with resilient wheel units
IPC: B64C25/00
Filed: 1938-06-03
Abstract: 517,373. Aircraft undercarriages. BOUND, R. H. June 3, 1938, No. 16747. [Class 4] In an aircraft undercarriage in which a landing element is supported at one side from a leg or rigid structure (which may be movable for retraction) by a deformable frame embodying shock-absorber means, a lever or arm carrying a spindle for the landing element, and the piston rod of a piston slidable in the lever or arm, are pivoted to the leg or structure on axes spaced one above the other, the pivot axes being substantially parallel to one another and to the axis of the spindle. The pivot of the lever or arm may be above the pivot of the piston rod or vice versa. In one form, Fig. 1, a lever 7 integral with the spindle of a wheel 9 is formed with lugs mounted on a pin 3 carried by an element 2 bolted to the lower end of a leg 1, thrust bearings being interposed between the lugs and the sides of the element 2. A link 5 is pivoted on a smaller pin 4 carried by the element 2 and to a piston 6 slidable in a cylinder 7C formed in the lever 7. Movement of the piston resultant on deflection of the wheel displaces liquid through passages in a partition 7D controlled by a valve 7E to move a floating piston 7G against the resistance of compressed air contained in the lower end of the cylinder 7C. The air may be introduced or released through a valve 7H. In a second form, Fig. 4, movement of a piston 36, corresponding to the piston 6, displaces liquid through passages 37E controlled by a valve 37F, to move a floating piston 41 against the resistance of compressed air contained in the hollow wheelcarrying spindle 38. The air may be introduced or released through a removable end wall 38A of the spindle. Specifications 473,756 and 473,768 are referred to.

Title: Electrophotographic process and apparatus
IPC: G03G15/26
Filed: 1963-04-29
Abstract: 1,028,493. Electrophotographic processes. KALLE A.G. April 29,1963 [Nov. 2,1962], No. 16824/63. Heading G2H. An electrophotographic process for making copies from transparent originals mounted on cards stacked alternately with leader cards which comprises feeding the cards in succession from the stack to a scanning system which stores data derived from the leader cards in an electrical memory device, exposing the original on each card to light a number of times determined by the data on the associated leader card, projecting successive images of the exposed original on to adjacent portions of a web of electrophotographic material, thereafter developing and fixing the resulting images on the web and cutting individual copies from the web. Cards carrying originals and leader cards are stacked alternately in magazine 3a, such that feed rollers 6, 7 feed a leader card beneath a scanning brush 9 and into a receiver 16. Impulses indicating the number of copies to be made are stored in a memory, not shown. An original is then fed by reciprocating knife 3 from the magazine 3a past a photo-electric cell 11, thus causing disengagement of a clutch (not shown) in the drive to the card feed mechanism. The original is thus arrested in the exposure zone in front of lens 20; lens shutter 21 is then opened to project a light image on to the web of electrophotographic material held stationary in a projection zone 28 through the optical system of Fig. 2 (not shown). The web is unwound from a roll 32 past a corona discharge 33 and through zone 28 by an intermittently driven roller 34. The web is withdrawn continuously from a loop formed by jockey roller 42 by rollers 43. The latent image on the web is developed by passage through a trough 48. and fixed by an infra-red heater 49. The shutter 21 is controlled by the memory (not shown) to produce the required number of copies in succession on the web which is cut into individual copies by a knife. 54. The original is ejected by the feed mechanism after the last exposure.

A device for holding the knife blade 3 of a verneer cutting machine with an upright wedge plate 1, having a supporting surface 2 for the knife blade 3 and an opposite surface 4 forming an angle with the surface 1, comprises a clamp 5 with inner surfaces 22, 14 forming a corresponding angle to each other, the arrangement being such that the knife blade is gripped tightly against the supporting surface by sliding the clamp 5 over the wedge plate 1 and knife blade 3. The clamp is supported between its ends by a bracket 10. The lower edge of the blade 3 rests against nuts 7 having flat surfaces which contact the surface 2 of the wedge plate. The blade 3 is adjustable by screw bolts 6 rotatably journalled in the clamp parallel to the surface 2 and screwed through the nuts 7. Screw bolts 8 threaded into the ends of the clamp and arranged to press on the upturned surfaces 9 of the wedge plate 1 allow the clamp to be lifted and the blade removed. The screw bolts 8 may be replaced by electromagnets or hydraulic means.

Title: Tag collector for use with a cash register
IPC: G06K13/02
Filed: 1961-05-16
Abstract: 904,768. Checking receipts. NATIONAL CASH REGISTER CO. May 16, 1961 [May 25, 1960], No. 17724/61. Class 106 (1). In a combination of a sales tag collector and a cash register, the deposit of a tag in a collector magazine closes a normally open switch in an energizing circuit for the driving motor of the cash register, and a control member, electromechanically actuated when the motor is energized, maintains the latter in energized condition until a cycle of operation of the cash register is completed, and also serves to close the switch if the motor is energized by a second, selectively operable, energizing circuit. A sales tag is placed on horizontal extensions 17 of a tag slide 15, slidably supported on an upper extension 7 of the back plate 6 of the tag collector. The tag slide is then moved to the right, in Fig. 2, under the control of a fullstroke mechanism, so that the tag passes below a slide block 11 and rests above the stack of tags in a magazine 42. As the tag is inserted, it rotates clockwise a series of switch arms 9 extending through slots in the extension 7. This, by means of an extension 26 on one of them, moves a latch arm 27 so that a notch 28 on it engages a switch arm 41 of a switch SC 24. The tag slide 15 is then moved back, leaving the tag in the magazine, and the arms 9 are spring-urged counterclockwise, closing the normally open switch SC24. Upon depression of any designated motorized key on the keyboard of the cash register, a switch SC41a1 Fig. 6, closes, completing an energizing circuit to the motor armature 54 of the cash register. This switch also completes a circuit to a tag solenoid L24, which, when energized, results in movement of a plunger 39 and, hence, of a trip slide 33 to the right (Fig. 2). A stud 35 of the trip slide engages and locks the twitch arm 41, until, at the end of the cash register cycle the switch SC41a1 is opened, the solenoid deenergizes and the trip slide moves to the left, so that the stud 35 releases the switch arm 41 and rocks a release arm 31 clockwise. This, by means of a stud 30, rocks the latch arm 27 so as to free the switch arm 41 and open switch SC24, thus conditioning the tag collector for a further operation. Further, selectively operable switches SC66b1, SC49a1 and ST44, are provided for ensuring the use of, or by-passing of, the tag collector and, when by-passing takes place, e.g. in total taking, the movement of the trip slide 33 closes the switch SC24 to maintain an energizing circuit to the cash register until the end of a cycle of operation.
