Title: Apparatus for scrambling signals
IPC: H04K1/04
Filed: 1942-05-11
Abstract: 563,471. Secret transmission. PATELHOLD PATENTVERWERTUNGS- & ELEKTRO-HOLDING AKT.-GES. May 11, 1942, No. 6364. Convention date, May 10, 1941. [Class 40 (iv)] In a system of secret telephony, message elements are differentially delayed to change their order, and the frequencies comprised in the message are separated into bands which are transposed, with or without inversion, in accordance with a constantly changing plan. Similar arrangements may be made for rendering secret the messages of a multiplex voicefrequency telegraph system. As shown in Fig. 1, a distributer R0 connects the signal line to telegraphone recording magnets A1 ... A4 in turn, and a second distributer SO connects pick-up magnets B1 ... B3 in turn to a circuit for separating the signal currents into three frequency sub-bands. These sub-bands are shifted in frequency in modulators M1 ... M3 which are fed with carrier frequencies which are. transposed from time to time by a device P. In a modification, Fig. 2, three distributers Sl ... S3, working on different plans, connect pick-up magnets B1 ... B3 in turn to filters F1 ... F3 respectively. These filters pass different frequency ranges, but the sub-bands are brought to a common frequency by modulators M1 ... M3 and are then shifted in frequency by modulators N1 ... N3 which are supplied with periodically varying carrier frequencies so as to produce a final signal in which the sub-bands are transposed, with or without inversion, in a manner which is constantly changing. In another modification, Fig. 4 (not shown), the original speech band is modulated by different (and repeatedly interchanged) carriers in three modulators, the outputs of which have a common frequency range (3150- 3850). Elementary portions of the resulting bands are then transposed in time by telegraphones and finally the bands are shifted in frequency so as to occupy the normal speech range. In a similar arrangement, Fig. 5 (not shown), the initial carriers are not interchanged, but the scheme of transposition in time is constantly varied. The periodical variations of carrier or transposing apparatus may be brought about by a group of relays P1 ... P4, Q1 ... Q4, Fig. 7, controlled in accordance with perforations in constantly running tapes V1, V2. A similar scheme is illustrated by Fig. 8 (not shown). The tapes and relays may be replaced by contact drums driven at an irregular rate in accordance with the shape of a cam-wheel controlling a step-by-step drive.

Abstract: 491,389. Valve amplifying circuits. SCOPHONY, Ltd., and JEFFREE, J. H. March 11, 1937, No. 7167. [Class 40 (v)] In a wideband amplifier operated from an alternating current supply an even number of valve stages is employed and the couplings of each stage are so chosen that the lower part of the frequency range, including at least the frequency of the supply, is amplified in the odd numbered stages and in the even stages the amplification of this frequency range is reduced to unity to remove hum. The overall gain of the system is arranged to be substantially the same for all parts of the frequency range. The Figure shows a valve 1 having a gain at one megacycle of 10 increasing to 100 at lower frequencies. The valve 2 at one megacycle also has a gain of 10 but at lower frequencies the gain is reduced to 1À4 at 100 kilocycles and to 1 at lower frequencies. The Specification gives the values for the components used in the couplings.

Abstract: 272,603. Avery, Ltd., W. & T., and Timson, W. March 17, 1926. Indicating-mechanism. - In a weighing apparatus having a gross, tare and net weight indicating device of the kind wherein one or more independent auxiliary pointers or indicating devices are provided in addition to the weight indicating pointer, the auxiliary indicating device or devices is or are disposed within the housing containing the weight indicating mechanism, the device or devices being rotatably mounted in bearings formed in or carried by the cover plate of the housing and having connection with an operating arm or arms disposed externally to the housing and adapted to coact with a flanged plate or plates secured to the housing whereby the auxiliary device or the chart can be maintained m any set position. In front of the usual weight indicating pointer 11<a>, Fig. 1, and pivotally mounted in concentric bearings upon the transparent cover plate 7 are two pointers 13, 19 for tare and gross respectively. The pointers 13, 19 may be rotated by external knobs 17, 22 connected by arms 15, 20 to the hubs of the pointers. The knobs may be clamped to flanged plates or discs 9, 14 by giving a twist to the knobs. The flanged disc 9 is fixed but the flanged disc 14 is secured to the hub of the tare pointer 13 so that when the knob 22 is clamped the pointers 13, 19 may be moved simultaneously by means of the knob 17 whereas the gross pointer 19 may be moved independently by clamping the knob 17 and unclamping the knob 22. In using the device after placing an empty container on the platform the gapped head 13<a> of the tare pointer is adjusted by means of the knob 17 to coincide with the weight pointer 11<a> and is clamped to the flanged disc 9. The gross pointer 19 is then set by means of the knob 22 to the desired gross weight and the material is added to the container until the pointer 11<a> coincides with the gross pointer. For subsequent weighings of the same net weight variation of the tare may be corrected for bv adjusting the pointers 13, 19 simultaneously by means of the knob 17. In a modification, the knob 17 carries a gear wheel which may be meshed with teeth on the flanged disc 9 to provide a fine adjustment for the tare pointer. In a further modification, Fig. 5, wherein the gross knob is dispensed with, the adjustment of the tare knob 23 sets a dial 32 which is graduated in the same manner as the weight dial 33. The tare dial is arranged in the same plane as the weight dial but is separated therefrom by an annular space within which the end 35 of the weight pointer travels. In use, the zero of the dial 32 is set to the tare weight as indicated by the pointer 35, and after filling the container the net and gross weights are indicated by the pointer upon the dials 32 and 33 respectively.
