Title: Method and Apparatus for Selectively Feeding and Severing Webs from a Plurality of Sources.
Inventor: GOODMAN ROBERT CHARLES
IPC: B65H20/00
Filed: 1967-11-07
Abstract: 1,176,730. Selective signalling. GAF CORP. 7 Nov., 1967 [10 Nov., 1966], No. 50663/67. Heading G4H. [Also in Division G2] In a paper feed for a photo-copying machine, copy paper is supplied in at least two different widths, the appropriate width being selected automatically by sensing the width of the original as it is fed to the machine. The required length of copy paper is also sensed automatically, and cut off. In the form shown, rolls 5, 7 supply copy paper 10, 12 of two different widths (e.g. 11 inches and 19 inches). These paper webs pass between respective pairs of feed rollers 43, 45 and 43<SP>1</SP>, 45<SP>1</SP>, driven by respective motors 44, 44<SP>1</SP>, then past a cutter bar 58, and are delivered on to a transfer belt 74. The original 14 is fed into a guide slot 40, passes between roller pairs 26, 27, and is also delivered on to the belt 74. This carries the two superimposed sheets on into the copying machine proper. From Fig. 4, it can be seen that as sheet 14 enters into guide slot 40, its leading edge may engage fingers 32, 33, 34 which actuate corresponding switches 29, 30, 31. The sheet 14, actually in phantom, is of the narrower width (11 inches), so that it actuates only the first two switches, 29, 30, in turn. This energizes a clutch 47 which connects the drive from motor 44 to roller 43, so causing copy paper 10 to be fed forward. When the trailing edge of the original disengages from switch 29, clutch 47 is de-energized, so that the motor drive to roller 43 is disconnected, and at the same time a braking arrangement 46 at the other end of roller 43 is brought into action to stop the roller and hence the motion of paper web 10. Also at the same time a solenoid 64 is energized, which rotates the cutter bar 58 to sever the sheet 10. The speeds of the various sheet-transporting devices is adjusted so that the sheets form a looped portion 81 at the approach to belt 74. This enables the part of sheet 10 which is being cut to be momentarily arrested although the forward end is still moving. It is also arranged that, after cutting, roller 43 is counter-rotated, so that the severed end of web 10 is withdrawn from the cutting station. Thus the station is left clear if a different web is to be fed forward next time. If sheet 14 has the wider of the two predetermined widths, the switches 29, 31, 30 are all actuated in succession. This causes clutch 47<SP>1</SP> to be energized instead of clutch 47. Thus the drive from motor 44<SP>1</SP> is connected to roller 43<SP>1</SP>, and hence the wider copy paper web 12 is fed forward through the cutter station, &c., the sequence of operations otherwise being as before. The operations are all controlled automatically by the electrical circuit of Fig. 8 (not shown).

A plug valve (not shown) especially for the filling and discharging of inflatable hollow bodies (11), such as rubber balls, which, if desired, may be filled with a liquid, comprises a sleeve (10) of rubber :or like resilient material adapted to be inserted in an inlet tube (12) of a hollow body (11), and having an axially slidable valve plug (4) therein which plug is provided with an interconnected blind bore (8) and transverse bore (9), the valve plug including a conical enlargement at each end with surface grooves. The sleeve (10) is of larger diameter than the tube (12) and is fixed to the tube (12) with adhesive whilst the diameter of valve shaft (4) is less than the inner diameter of the sleeve (10). Interconnection between a valve pump and the interior of the body is by a tube (13) fixed to a boss (1), the pressing of said tube on to the boss causing inward movement of the valve plug and opening of the air passage to the body interior whilst the removing of this tube causes outward movement and sealing of the-passage between the bore (9) and the body interior by one of the grooves (6) binding against the sleeve. The binding of one of the grooves (3) against the sleeve holds the valve plug firm during pumping. A further transverse bore is interconnected with the blind bore, this bore being adjacent the outer conical enlargement and being fitted with a membrane resiliently surrounding the valve plug or with a whistle causing audible escape of excess air when the pressure of the body interior increases beyond the desired amount.

Abstract: 1,169,228. Variable-ratio gears. FICHTEL & SACHS A.G. 18 Nov., 1966 [20 Nov., 1965], No. 51800/66. Heading F2D. [Also in Division D1] The input shaft of a planetary gear is rotated forwardly or reversely to provide either unidirectional drive at two different ratios or bidirectional drive at a different ratio in each direction. The arrangement may be used in an ironing machine to provide either unidirectional drive of the ironing rollers at two speeds, or to drive the ironing rollers at one speed and the ironing trough in the opposite direction at a second speed. As shown, unidirectional drive is provided by a gear having an input sun 3 meshing planets 4, 5 connected to respective spindles 9, 10 by oppositely acting ratchet clutches 7, 8. The spindles 9, 10 are mounted in a common output carrier 6, the spindle 10 being fast with a planet 12 meshing a freelyrotatable suit 13, and the spindle 9 being fast with a planet 11 meshing an idler planet which also meshes the sun 13, the idler planet being fast with another planet meshing a stationary ring gear 17. In one direction of rotation of the sun 3 the planet 4 drives its spindle 9 and hence the planet 11, the idler planet and the planet reacting on the stationary ring gear to drive the carrier forwardly at a first ratio. In the other direction of rotation of the sun 3 the planet 5 drives its spindle 10 and hence the planet 12, sun 13, idler planet and the planet reacting on the ring gear to drive the carrier forwardly at a second ratio. In an arrangement for bidirectionally driving an output carrier, an input sun meshes two planets connected to their respective shafts through oppositely acting oneway clutches. Both trains are essentially similar, each comprising a planet fast with the planet shaft and meshing a step of a planet having a second step meshing a stationary ring gear.

Title: Signal compression apparatus
IPC: G01S13/44
Filed: 1964-12-23
Abstract: 1,077,938. Monopulse radar. NORTH AMERICAN AVIATION Inc. Dec. 23, 1964 [Dec. 23, 1963], No. 52323/64. Heading H4D. Broadly related to any two channel system, wherein discrete gain variations in one channel are accompanied by corresponding discrete gain variations in the other channel, the Specification particularly describes a monopulse radar receiver, wherein the two channels are the sum and difference channels and the gains in both channels are simultaneously decreased in discrete steps as the amplitude of the sum signal increases. The resulting simultaneous compression of the channel outputs is stated to make for easier system design to remove certain errors. In the most detailed embodiment (as shown), a signal combining means produces the sum and difference signals (A+B) and (A-B) respectively at IF. The sum channel and the difference channel each comprise a plurality of identical IF amplifiers 28a . . . etc., in cascade. In addition to being connected to the input of the next amplifier, each amplifier output is detected in a video detector 29a . . . etc., and the detector outputs are combined in video scanning amplifiers 33 and 34, to produce signals # and #. The outputs of first detectors 29a and 29a<SP>1</SP> are fed directly to their respective video scanning amplifiers but the outputs of all the other detectors are fed thereto via switches 19. A switch in the sum channel and the corresponding switch in the difference channel are simultaneously controlled by a Schmitt trigger 30, fed with the output of the sum channel detector. Thus as the sum channel gets progressively larger, first the last trigger, then the penultimate and so on, trigger, such that the switches 19 are progressively opened and the outputs of the summing amplifiers are simultaneously compressed to a more workable dynamic range. The sum (#) and difference (#) outputs of the video summing amplifiers are passed to a logarithmic difference amplifier which produces at two outputs respective signals both representing the angular deviation # of the target from the boresight axis, but of opposite polarity. The sign of the deviation is determined by passing the outputs of the last amplifier in each chain to a phase detector 22 which produces a pulse which, via Schmitt trigger 31, operates switch 23 to select the signal of the correct sign. In a second embodiment, Fig. 4 (not shown) the IF sum and difference signals are fed without detection to the summing means the video detection taking phase on the summed signals, and the Schmitt triggers are replaced by threshold amplifiers. The amplifiers may be arranged in parallel and have their outputs switched to the summing means under the control of a multithreshold discrete gain switching means at the input to the sum channel, Fig. 2 (not shown). Transistorized embodiments of various means shown in Fig. 5 are described and shown, Figs. 6, 7, 8, 9, 10 (all not shown).
