Abstract: Material with asymmetric conductivity, for use for example in p rectifiers, is made by heating together copper and sulphur, the former being in excess of the amount necessary to form cuprous sulphide, to a temperature of about 1100--1200 DEG  C. until substantially complete combination of copper and sulphur is obtained. In one example, substantially four parts of copper to one of sulphur are slowly heated in a loosely closed vessel in a furnace until the sulphur begins to burn, the heat being gradually increased to 1200 DEG  C. and maintained for about five minutes, the mixture being then poured into a container and allowed to cool. The cooled material may be ground to a fine powder and compressed at a pressure of from 7 to 23 tons per square inch into the form in which it is required for use.

Abstract: 127,279. Billant, L. L. Oct. 11, 1916. Projectiles; projectile fuses. -Consists in providing in a grenade a plug carrying at its upper end a spring which is formed at one or both ends as a firing pin or pins for igniting a timefuse, the pin or pins being normally held in the safe position by means of one or more locking-pins under the control of an external lever. In the construction shown in Figs. 1 and 2, the plug C has a recess in which is a transversely-disposed spring D, one end of which forms the firing-pin. The spring is pivoted at I and is held cocked by an axial pin E retained in place by an external lever. F. A spring G bears on the head of the pin E or directly upon the lever F. When the lever is released from the thrower's hand, or by the grenade passing out of a discharging-tube such as that shown in Fig. 1, the spring D is freed and its end strikes a cap a, igniting the time-fuse.. The spring E may have two branches which act on two caps simultaneously; or a straight helical spring, normally held at its ends by forked pins, may be used. In a further modification, the locking-pin E is pivoted to the lever F. A sleeve of leather or the like may surround the pin E, to exclude moisture. The base of the grenade is slightly convex, in order to strengthen it. Guiding-rings b which closely fit the bore of the discharging-tube, are formed on the body of the grenade.

Title: Multi-channel modulating arrangement
IPC: H04J3/02
Filed: 1975-04-09
Abstract: 1489284 Multiplex systems COMPAGNIE EUROPEENNE DE TELETRANSMISSION 9 April 1975 [12 April 1974] 14710/75 Heading H4M In a multichannel modulating arrangement for multiplexing binary digital signals received at n inputs in different modulation forms (amplitude, phase or frequency) and at differing bit rates, the successive bits of each input signal are grouped in n channel circuits in groups Pi. The output groups of the channel circuits are sampled cyclically, such that the sampling circuit delivers a multiplexed signal comprising a plurality of samples of each group. The sampling circuit output is fed to a coding arrangement which in accordance with the samples delivers successive address signals to a read only memory in which are stored coded binary words representing points of a sinusoidal wave form. Particular words are read in accordance with the successive addresses corresponding to the signal modulated inputs. Data at different bit rates, modulation levels and form of modulation is fed to input 1-3 (Fig. 3). The received bits on each channel input are grouped by means of shift registers and buffer stores 11-13, 21-23 controlled at rates appropriate to the data on the different channels from a sync. generator 10. The groups contain a number of bits not greater than the number of inputs. The data groups in the buffers are then sampled. The sampling system incorporates AND gates 211, 221, 231, controlled in accordance with the multiplex rate by outputs B 1 , B 2 , B 3  of the sync. generator, together with OR gates 31, 32, 33, 34 and decoder 300. The sample for each group is derived by sampling each bit of the group and the channels are sampled cyclically to deliver a multiplexed signal as bit-words formulated in parallel on the 16 output lines of the decoder 300. These outputs are applied to a coding arrangement including coders 40 and 50 (Fig. 4). Coder 50 is controlled from the sync. generator 10 using outputs B 1 -B 3 , C 1 -C 3  to correctly extract the data corresponding to the different phase and frequency modulations in the input channels. The coding arrangement develops for each sample of the multiplex signals address signals which are applied to a read only memory 80 in which are stored the coded binary words representing points in a sinuosoidal waveform. Thus a sequence of samples representing the sinusoid modulated by the different inputs is delivered and the samples can be successively read by demultiplexing registers 501-503 and A/D converters 601- 603 to provide the channel outputs. The data from the coder 50 indicates whether the input to the coding arrangement is phase or frequency shifted and is combined in the adder 60 with information from an operating store 150 and an initial phase store 100, set in accordance with a previous address for the same channel held in the register 70 to produce the next address for the read only memory 80. The memory output is multiplied in the unit 90 with amplitude modulation data extracted by the coder 40 to provide the signal for transmission.
