Abstract: 200,658. Lock, T. J., and Sprenger, G. C. May 31, 1922. Stapling.-A stapling machine forms a staple and holds it while the curved and straight ends are bent at right angles to the body of the staple, which is then driven into a ticket, formed from printed web paper, with the pointed ends of the staple ready for attachment to any material, while the curved end of the staple is passed round the edge of the ticket and wiped underneath it. Wire is fed through a guide 1, Fig. 4, into grooves 3 in blocks 2, and also passing through a groove 6 in a plunger 5. The plunger is carried on a block 7 in a slide 8, and is operated by a bell crank 9, Fig. 2, engaging a cam on a main shaft 11. The wire is cut by a knife 12, Fig. 4, on the slide 7, and a staple is formed by the plunger 5 pressing the wire between the blocks 2. The complete staple is pressed into grooves 18, Fig. 5, between spring fingers 16 pivoted to a fixed frame 14. Within this frame a slide 19, Fig. 6, carries rams 24, 25, which engage opposite ends of the staple, the middle being supported in the groove 18. Thus the curved end of the staple and the two straight ends are bent downwards. The staple is now driven into work 31 by a ram 26 operated from an arm 27 off the printing platen, which is driven by a rod 30, Fig. 2, off the shaft 11. The rams 24, 25 are operated by a rod 21, Fig. 2, and bell crank 22 engaging a cam on the shaft 11. The staple ends penetrate the work 31, and the curved part of the staple passes down at the end of the work and is turned underneath it by a wiper 33, Fig. 6, which is pivoted at 34 and operated by a rod 35 connected to a crank 36 &c., Fig. 2.

Filed: 1942-11-02
Abstract: 565,212. Feeding webs. WILCOX, R. L., and WATERBURY FARREL FOUNDRY & MACHINE CO. Nov. 2, 1942, No. 15386. [Class 100 (i)] [Also in Groups XXII and XXIV] Means for intermittently rotating the feed rolls 11, 12 of a heading or other machine, comprises a toothed clutch part 28 adapted to drive the rolls, a corresponding toothed clutch part 31, which is given a predetermined rotation and can be moved axially to open and close the clutch, means 46 to ensure tooth alignment of the parts 28, 31, when being engaged, and a stop 42, which prevents control means, for closing the clutch, from being operated when the part 31 is rotating in the direction to operate the feed rolls. The part 31 has a half hub 32 engaged by a complementary half hub 61, Fig. 2, of a member 29, which is oscillated about the shaft 14, through an adjustable angle by cam mechanism 30, 55, 56 so that the part 31 is also oscillated. This part is free to be moved axially by a handle 39, shaft 34, arm 35 and a roller 37 engaging a slot 38 in the half hub 32. When the clutch 28, 31 is engaged, the oscillations are transmitted to one part 21, Fig. 1, of a roller-ratchet clutch which thus imparts intermittent clockwise rotary movement to the other part 19 and to the feed rolls 11, 12, retrograde movement being prevented by a brake 44. The aligning means may comprise a spring ratchet 46 carried by the clutch part 28 and always in engagement with the teeth of the part 31 so that counter-clockwise rotation of this part is transmitted to the parts 28, 21, but the part 19 is not affected. The stop 42 is kept in operative position by a spring 60 during the counter-clockwise movement of the part 32, whether the feed rolls are being driven or the clutch 28, 31 is open, so that an insufficient length of the workpiece cannot be fed. During the clockwise movement of the part 32, the work is not being fed and the stop 42 is withdrawn by a cam 59.

Abstract: 725,755. Gramophones. BROWNE, H. E. June 4, 1953, No. 15487/53. Class 40 (2). In a simple gramophone, suitable for use in dolls and other toys, an operator's control moves the stylus from one part of the record groove to the start of the record groove and actuates the motor control. A turntable shaft 21 is supported by limbs 15a and 15b of a bracket 15, the lower limb 15b carrying an electric motor 18, the shaft 27 of which is pressed against the rim 24 of the turntable 16 on account of the resiliency of the limb 15b. The motor 18 is driven by a battery contained in a housing 14. The sound-box 19, which comprises a casing 30 and a radiating diaphragm 28 with stylus 29 attached directly thereto, is mounted on a resilient arm 32 on a shaft 31 which may be moved endwise by manual means against the tension of a spring 35 to lift the sound-box from the record. The spring 35 also acts rotationally when the sound-box has been lifted to automatically return it to a stop 37 representing the start of the record. A rigid arm 34 serves to hold the sound box out of contact with the record when the shaft 31 is lifted. The lifting means for the shaft 31 comprises a pivoted lever 41 and a push rod 40 having an end forming a push button 39. The movement of the soundbox to the starting position causes an arm 36 to establish an electric circuit through a contact 38 to drive the motor 18. When the stylus reaches the end of the record the contact between arm 36 and contact 38 is broken.

Title: Device for separating from a time modulated multi-channel pulse train a pulse train belonging to a desired channel and converting the latter pulse train into a duration modulated train
IPC: H03K11/00
Filed: 1950-12-19
Abstract: 727,777. Multiplex pulse signalling. TELEFONAKTIEBOLAGET L. M. ERICSSON. Dec. 19, 1950 (Dec. 19, 1949], No. 15737/53. Divided out of 716,371. Class 40 (5). In a multiplex system of time-modulated pulses positive-going gate pulses corresponding to a selected channel are applied to the control grid of a multi-grid valve 1 and negative-going time-modulated pulses of all the channels to the suppressor grid through a capacitor 2. Pulses of the selected channel applied to the suppressor grid lower the screen grid potential and this applied through a large capacitor 12 between the screen and suppressor grids maintain the latter biased to cut-off after the channel pulse has ceased, due to the time constant of the screen grid circuit (comprising resistors 14 and capacitor 12). Anode current pulses of duration equal to the interval between the beginning of the gate pulse and the channel pulse therefore flow in the anode circuit and are demodulated by a low-pass filter 5. The suppressor grid may be given a small positive fixed bias to prevent the gate pulse along, by initiating screen-grid current, lowering by feedback the suppressor grid potential to cut-off.

Abstract: 1,144,181. Proximity switching arrangements. OWENS-ILLINOIS Inc. April 12, 1966 [April 12, 1965], No.15823/66. Heading G1N. The invention relates to apparatus for inspecting sealed containers on a high-speed-conveyer, in which the desired degree of vacuum in the container is indicated by a flip panel whose position is detected by a proximity switch. The containers on the conveyer are guided to the inspection position by side plates (32), (34) Figs. 1, 2 (not shown). To allow for minor variations in the height of the containers, or tilted lids (due to improper threading), the proximity switch is mounted in a spring-loaded floating head, Figs. 1, 4 (not shown). To suppress false signals from the leading and trailing edges of the lid, a second proximity switch (204) Figs. 8, 9 (not shown), is arranged beside the container, so that the flippanel-detector is only operative when the container is in position under the floating head. Dud containers are rejected by a pneumatic ejector which punches them sideways off the conveyer. The proximity switching element may form part of an oscillator circuit associated with a monostable flip-flop and relay.
