Title: Method and Apparatus for Signal Alteration.
Inventor: GREENBERG SANFORD DAVID
IPC: G10L21/04
Filed: 1967-03-08
Abstract: 1,173,682. Signal compression system. S. D. GREENBERG. 8 March, 1967 [8 March, 1966], No. 10818/67. Heading H4R. In apparatus for compressing signals, Fig. 1, the signals are recorded on a magnetic tape 12 and replayed at a higher speed, so that they occupy a shorter time and are multiplied in frequency. The output from the tape is then fed into a tapped delay line the taps of which are scanned by a switch 22 at a speed which is related to the speed of the signals in the line such that the output from the switch has the same frequency as the signals originally recorded on the tape 12, but the signals occupy the same time as at the output from the tape. In an example the tape is replayed at twice the speed at which it was recorded and the delay line taps are scanned at half the speed at which the signals travel in the line so that during the scanning a signal sample reproduced stretched to occupy twice its duration at the input to the line while the samples are separated by a time equal to their original length, the signal during the intervening period being lost and replaced by the stretching process. The delay line may be a lumped constant electrical line or an elastic fluid filled tube with pairs of capacitor plates arranged along its length. An acoustic wave is generated at one end of the tube so that it travels along the tube and causes the spacing between the pair of plates, and therefore their capacity, to vary in accordance with delayed versions of the input signal. The capacity variations are detected, by causing them to frequency modulate an oscillator, to provide the delayed signals to be sampled sequentially. The switching speed may be synchronized with the tape speed by arranging that the tape drive generates repetitive pulses which are used to operate the stepping of the switch from one line tap to the next. Also described is a tape mechanism for eliminating the gaps in speech which is the subject of Divisional Specification 1,173,683.

Title: Improvements in or relating to change-speed gears
IPC: F16H61/02
Filed: 1925-04-29
Abstract: 255,557. Hinton, A. G. April 29, 1925. Variable-speed gearing comprises a plurality of gear wheels B - - F, Fig. 1, mounted about a common shaft A each deriving its motion solely by interaction with its neighbours, one of these wheels such as B being fast on the shaft A and another such as 'E absolutely fixed. Wheels C and D carry planetary pinions J, K meshing with bevel teeth on the neighbouring wheels. Pinions 'L similarly arranged in the fixed wheel E cause the wheels D, F to turn oppositely. The shaft A may be an extension of the power shaft of a vehicle, in which case the wheels B, C, D are driven at different speeds forwardly, and the wheel F reversely. The peripheries of the gear wheels B, C, D. F are adapted to be selectively clutched to a driven shaft 12. For this purpose a hollow drum or cage 10 is slidably feathered on the shaft 12 and carries a clutch band 9, Fig. 2, which can be moved over any gear wheel by actuating a lever 16, Fig. 3, and can be contracted to grip the wheel by depressing a pedal 15 thereby effecting a differential sliding of a clutch-operating rod 7. Alternatively the clutch may comprise rollers 23, Fig. 4, held against the wheels B &c. to grip frictionally by means of spring arms 24 carried by the head of the cage 10.

Title: Improvements in or relating to machines for the production of envelopes or the like
IPC: B31B160/10
Filed: 1960-03-30
Abstract: 904,833. Feeding sheets. WINKLER, R., and DUNNEBIER, K. March 30, 1960 [May 21, 1959], No. 11153/60. Class 100 (1). [Also in Group XVII] Sheets or blanks are fed, for example to envelope-making machines, by mechanism, wherein individual sheets or blanks from a sequence in overlapped formation are fed by a first conveyer to segment rollers which cooperate with counter-rollers to act as a stop, at their mutual contact point, for each blank and then to withdraw the blank from the overlapped formation and transfer it to a second, faster-running, conveyer. In one form, two segment rollers 16, 17 are mounted on a shaft 14, Fig. 1, in contact with two rollers 28, Figs. 4 and 5, which may be covered with resilient material. A crank arm 27 projects from the shaft 14 and is actuated in synchronism with the folding mechanism (to which the individual blanks are forwarded) through means, not shown, which cause the segment rollers 16 to rotate in the direction T so that, when the leading one of the blanks 6 of the sequence reaches the rollers, it is halted at the contact point between them, Fig. 4, and as a result of the feed movement of the belts 5 it arches up between that point and following rollers 7. The crank arm 27 is then actuated to rotate the rollers 16 in the direction U and the blank is gripped and accelerated between the rollers, which transfer it to a conveyer 33 which forwards it in the direction S to the folding machine. The spacing between the shafts 14, 15 of the rollers 16, 28 is adjustable by swinging the bearings 46 of the shafts 16 about pivots 20, Fig. 2. The rollers 16 are mounted on the shaft 14 so as to be movable along it and their spacing is adjusted so that they are somewhat further apart than the corner excisions at the leading edges of the blanks 6. The rollers 7, which press down the staggered blanks on their feeding belts 5, are rotatable in two carriages 8 which are pivotally mounted at the ends of arms 10 which extend from a cross-bar 13 on which they are longitudinally and transversely adjustable. Rollers 38, above the conveyer 33, are similarly mounted. In another form, Figs. 8 and 9, two similar segment rollers 53, 55 are concentrically mounted, there being two such pairs, laterally adjustable by an opposite-handed screwthread device. The rollers 53, 55 of each pair are rotated in opposite directions, through gearing. When the leading edge of a blank 6, travelling in the direction R, reaches the rollers the segment lobes are as shown in Fig. 8 and the blank is halted at the contact point between the rollers 55, 68. As the rollers continue to rotate in opposite directions they reach the Fig. 9 position, when all four segment lobes coincide, and the segments 55 release the blank and it is gripped between the segments 53 and the counter rollers 68 and thus forwarded to the conveyer 33.
