Abstract: .240,476. Semenov, I. A. Sept. 24, 1924, [Convention date]. Paper tubes.-In making paper tubes from a continuous strip of paper, e.g. in cigarette machines or wrapping machines, the edges are stuck together by a pressure-applying surface which is in continuous movement so that portions of the surface to which adhesive clings are moved forward to a position in which the surface can be easily cleaned. In one form of apparatus the paper strip, Fig. 1, carrying ,adhesive 2 is carried through a shaping tube 3 by a linen strip 4 and is pressed by a drum 9 carried on an arm 5 pivoted at 6 and rotated through pulleys 12, 13 and a bolt 14, adjustment of pressure being effected by a set-screw 11. If empty tubes are being made, a plate 10 is provided to support the pressure. The drum is heated from a burner 19 through a metal block 20 and is cleaned by an endless belt 17 passing through a water bath 18. In a second form of the apparatus shown in Fig. 3 the pressure is applied by an endless metal band 5 passing around driven pulleys 6 and 7, and cleaning is effected by a moist band 19 dipping in a bath and applied to the surface to be cleaned by a roller 11. Heat may be applied as before, or the heating block may be warmed electrically.

Title: Improvements in or relating to means for generating oscillations at equally spaced frequencies
IPC: H03L7/20
Filed: 1948-09-20
Abstract: 670,877. Automatic frequency control systems. PHILIPS ELECTRICAL, Ltd. Sept. 20, 1948 [Sept. 23, 1947], No. 24549/48. Class 38 (iv). An arrangement for producing frequencycorrected voltages, at frequency intervals or steps of identical frequency spacing, makes use of a control oscillator giving the desired frequency steps, the controlled oscillation being mixed with the spectrum produced by the control oscillator to give a frequency-correcting control voltage which locks the controlled oscillator at a frequency equal to that of the nearest spectrum component. The control oscillator may be a pulse generator giving a spectrum of harmonics, or may be a sine-wave oscillator frequency-modulated by a source generating the spacing frequency. In Fig. 1, the pulse generator 1 and the controlled source 2 feed a mixer 3, the output of which is taken through a low-pass filter 4, the cut-off frequency of which is about half the frequency spacing of successive spectrum components. The filter output is taken to a frequency control device 5, such as a thermionic reactance, associated with the source 2. The frequency is always stabilized at that of the nearest spectrum component, and jumps from one to the next as the manual tuning is steadily advanced. The stabilized frequencies may be raised or transposed in frequency by heterodyning with a stable source. In a modification, Fig. 2, the transposition frequency is introduced by an oscillator 8 which mixes its output at 7 with the output from the first mixer 3. The output from the mixer 7 is taken through a low-pass filter 9 to a frequency control 5 of the controlled source 2, which is thus kept at a given frequency separation from the selected component of the spectrum provided by the control source 1. The oscillator 8 may be adjustable in steps by the arrangement of Fig. 1, and its steps may be one-tenth or onehundredth of those of the source 1 so as to provide a decade scale. Specification 640,351 is referred to. The Specification as open to inspection under Sect. 91 includes a modification in which the filter 4 of Fig. 1 is replaced by a tuned discriminator, Fig. 2 (Cancelled, not shown). This subject-matter does not appear in the Specification as accepted.
