Patent GB-777092-A (GB)
Title: Improvements in or relating to counting devices for the automatic control of the advancement of a movable structure
IPC: G05B19/04
Filed: 1955-06-22
Abstract: 777,092. Machine-tool details. WERNER, H. H., and RUDIGER, F., [trading as WOHLENBERG KOMM.-GES., H.]. June 22, 1955 [June 25, 1954], No. 18052/55. Class 83 (3). [Also in Groups XIX; XXXVII, XL (b)] A predetermining-counter for controlling a machine-part comprises means for setting said counter forwardly to a selected number, and other means for rotating said counter rearwardly to zero. The counter comprises four numeraldrums 10, Fig. 1, each having a set of ten spirally-disposed projections 15. Below each drum are ten stops 16, each carried by a spring- member 35, Fig. 2, on a spindle 18. Each stop 16 can be raised to an active position by depression of a corresponding key 21 of a keyboard. Upon depression of a push-button 59, Fig. 4, a relay 42 is energized to close the circuit of a motor 54 which, through a belt-drive and individual-clutches 81, rotates each drum to the position determined by the selected stop 16 engaging the appropriate stop 15, Fig. 2, whereupon a relay 41, Fig. 4, is energized to close the circuit of an electromagnet 37 which moves a bar 38 and retracts the actuated stops 16, Fig. 2, thereby stressing the associated springs 25. The motor 51, Fig. 4, is energized and, through a belt 50 and a coupling 49, drives the machinepart 48, whose movement is to be controlled by the counter. The drums 10 are thus driven backwardly to zero via the belt 57, shaft 58 and gears 52. When the drums reach zero, slots 14 therein are aligned so that light from a lamp 13 strikes a photo-cell 11. An additional slot 14, or a single double-size slot 14, is provided on the second-order drum so that the photo-cell 11, or a second such cell, receives the light from the lamp 13 or a second lamp before the counter reaches zero. Upon the first energization of the photo-cell 11 a thyratron 56 fires and energizes a relay 44 which causes the thyratron to extinguish and actuates switches which effect, e.g., reduction of the speed of the driving-motor 51. When the photo-cell 11 is energized for the second time the thyratron 56 again fires to energize a relay 45 which disconnects the coupling 49 and stops the part 48. The first order of the counter may comprise a transparent drum, Fig. 3, which is connected via gears 34, 33 to a cam 31 whose follower is carried by a shaft 29 which also carries a disc 27 having an aperture 28 and the photo-cell 11 and light source 13. The arrangement is such that when the counter is set the aperture 28, cell 11 and lamp 13 are rotated to the appropriate angular position. The setting of the stops 16 may be effected by a punched card 17, Fig. 2, the columns of which have holes in positions corresponding to the selected stops 16, above which the card is located.

Title: Improvements in and relating to book binding
IPC: B42D1/00
Filed: 1927-07-07
Abstract: 285,306. Spicers, Ltd., and Larmour, J. July 7, 1927. Bookbinding.-In bookbinding, the back edges of single sheets are so cut that when assembled into a book they form a number of dovetail recesses in the back of the book for the reception of a corresponding number of interlocking members. The interlocking members may be made of leather, indiarubber, or webbing &c., and are secured by glue or cement. Fig. 1 shows a book 2 with dovetail recesses 1 within which canvas or webbing strips 3 are inserted upon a layer of glue, the ends of the strips being secured upon the sides of the book. A further layer 4 of glue may be applied behind the strips to fill any spaces in the recesss. Heavy books, such as account books, are provided with deep dovetailed recesses in their back edge and the leather or indiarubber binding members inserted therein are bevelled in order to fit closely. In a modification, Fig. 5, alternate dovetails in each sheet 2 are cut away, the wide recesses thus formed in one sheet being staggered relatively to those of the sheets on either side of it when the sheets are assembled into book form for the insertion of the binding members within the straight recesses 1. In another modification, Fig. 7, the recesses in the edges of the sheets are each cut with a straight edge 6, so that by reversing alternate sheets the back edges of the assembled sheets form dovetailed recesses 1 with adjacent rectangular reces&es 7, Fig. 8, the binding members being inserted within the recesses 1; the recesses 7 allow thick books to open out flat when bound in this manner. To reinforce the interlocking or binding members the backs of the books may be covered with a flexible binding of canvas, leather, &c.
