Abstract: 874,815. Stencilling addressing-machines. USSELMANN, F. May 26, 1959 [June 9, 1958(2)], No. 17912/59. Class 100(2) Stencilling-apparatus wherein stencils are fed between a rotatable printing segment and backing means engageable with the segment during a part of eachrevolution thereof comprises means for dispensing ink to an inking roller rotatably supported adjacent to the path of the segment, and means for separately rotating the segment and the roller at the same peripheral velocity, so that the segment receives ink from the roller during one part of each revolution and forces ink through the stencil on to a receiving element during a different part of each revolution. Stencil address-plates from a magazine D, Fig. 1, are fed in succession along guideways 22 on a table B to printing position between an inked rotatable printing segment 3 mounted on a shaft 2 and a backing cylinder 8, and thence to a receiver F. Envelopes on a web to be printed are fed by hand or automatically below the stencils and to a shoot E. Inking-apparatus. An ink reservoir 30, Fig. 2, is filled through an aperture normally closed by a  plug 46 having a shank 47 acting as an ink gauge. Vents 50, 52 allow venting of air during filling and entry of air during use. Ink is ejected by raising a knob 37 manually and releasing it, a spring 33 forcing down a piston 31 to deliver ink, which has entered the cylinder 34 through ports 35, 36, through outlets 45, a ball valve 43 preventing return flow. An ink-dispensing roller 53 receives ink from the outlets 45 and is mounted on arms 54 on a shaft 56, being rotated by a belt 5 from a shaft 1. An inking roller 60 is mounted on arms 62 on the shaft 56, and its downward movement is limited by a stop screw 66 abutting a spindle 26. The roller 53 rests on the roller 60, thereby rotating it and supplying ink thereto, which is transferred to the segment 3 during a part of the revolution of the latter. The shaft 1 is driven through a belt 85, Fig. 5, and a chain 75 from a motor or hand-driven drive shaft 71. The roller 53 is axially reciprocated by means of a cam disc 57 engaging a groove in a part 59. There may be two such inking-mechanisms coaxial in the machine. Driving-mechanism; stopping-mechanism. The shaft 71 drives the shaft 72 and thence the shaft 2 through a notched ring and pawl clutch and a chain 87. The clutch is released by pressing a rod 99 into the path of the pawl 93 when a stencil is to be skipped, a spring-urged roller 106 engaging a depression 107 in a part rotating with the segment stopping the latter in the correct position. Stencils are fed by a pusher 126b reciprocated through linkage 119, 125 from a part clutched to the shaft 71 by a pawl 113 released by a manually operated rod 114 for repeat printing. The shaft 71 may be driven by a handle thereon, having a detent to facilitate stopping in the correct position. Cylinder trips. The cylinder 8 is oscillated about a pivot 11 by a cam 14 on the shaft 15, which may be the same as the shaft 71, in synchronism with the drive of the segment 3.

Title: Electronic timepieces
IPC: H03K23/00
Filed: 1974-04-24
Abstract: 1432513 Electronic timepieces SUWA SEIKOSHA KK 24 April 1974 [25 April 1973] 17931/74 Heading G3T [Also in Division G4] In an electronic timepiece comprising an oscillator A, Fig. 1, followed by a frequency divider B the output f 1  of which operates a display D via a signal transforming means C, there is provided a memory M which controls the divider B periodically in dependence upon data stored therein,  whereby to regulate the divider output to give signals of a predetermined periodicity (e.g. 1 second). The functions of the memory M and divider B are complementary, i.e. the memory preferably has a count-down function and the divider a countup function. The number of pulses f o  occuring in exactly one second is written into the memory M by a gate P, Fig. 2, which is opened for exactly one second by two successive pulses applied at S and having one second between them. If the memory has a subtraction function the data obtained by subtracting f o  from zero is written into the memory. A gate signal generator F opens gate circuit G each time a 1 second pulse f 1  occurs and consequently data stored in the memory is written into the divider B, and one second thereafter the divider counter B content becomes zero. Thereupon a pulse f 1  is produced and the cycle is repeated with a periodicity of exactly one second. The frequency of signal f o  may be between 1 MHz and 2 MHz. Whatever may be the frequency of f o  there is obtained a signal f 1  having a period of exactly one second. Preferably the memory M is of a type which retains the state it adopts when data is written into it, even if the power supply battery is disconnected. The display may indicate time of day and date and may be electro-optical (e.g. liquid crystal or light emitting diodes) or may comprise hands driven by an electric motor. C-MOS integrated circuits are used, formed by 'silicon-gate technique' or 'silicon-on-sapphire (SOS) technique.'
