Patent GB-608698-A (GB)
Title: Manufacture of highly polymeric carbamates
IPC: C08L75/00
Filed: 1946-02-27
Abstract: Thiolcarbamates of the formula HO.R.NH. COSR1 (where R is an alkylene, cycloalkylene, or arylene residue such that more than 3 carbon atoms separate the OH and NH groups, and R1 is a monovalent organic residue which is capable of forming a mercaptan and which will not react with a hydroxyl or isocyanate group) are auto-condensed by heating them, singly or mixed, above their melting point.  The conditions are preferably such that the mercaptan produced can be removed from the reaction zone, e.g. by distillation during which, or part of which, pressure may be reduced and a stream of oxygen-free gas (e.g. nitrogen) may be passed through and/or over the reaction mass.  The products may be formed into filaments, blocks, chips or other shapes by conventional means.  In examples: p-tolyl 1-hydroxypentan-5-thiol carbamate and/or p-tolyl p-hydroxyphenyl thiolcarbamate is heated in the presence of nitrogen first at atmospheric and then at reduced pressure.  Specifications 599,178 and 599,179 are referred to.  p - Tolyl 1 - hydroxypentan - 5 - thiolcarbamate and p-tolyl p-hydroxyphenyl thiolcarbamate are prepared by reacting p-tolyl thiolchloroformate with 1-hydroxy-5-amino-pentane and p-amino phenol respectively in the presence of dimethyl aniline and alcohol at 0-10 DEG C.ALSO:Thiolcarbamates of the formula HO.R.NH.COSR1 (where R is an alkylene, cycloalkylene, or arylene residue such that more than 3 carbon atoms separate the OH and NH groups, and R1 is a monovalent organic residue which is capable of forming a mercaptan and which will not react with a hydroxyl or isocyanate group) are autocondensed by heating them, singly or mixed, above their melting point.

Title: Data indicator unit
IPC: H04L9/18
Filed: 1976-02-17
Abstract: 1505771 Data indicator and enciphering/deciphering unit GRETAG AG 17 Feb 1976 [24 Feb 1975 12 Nov 1975] 06241/76 Headings G4H and G5X An indicating unit comprises indicator means 2, an input keyboard 60 by means of which the indicator means can be selectively activated, and a switching unit 9 having a number of different possible switching states for selective control of the individual indicator means. In the embodiment of Figs. 3-4, the indicator means are LEDs associated with an array 3, 4 of alphanumeric labels. Selection of a number 01-32 on keyboard 60 causes a decimal output 93 therefrom to be converted to binary form 91, stored 92, then entered in a shift register 80 for application to a binary/decimal decoder 9. In the embodiment of Figs. 1-2 (not shown), keyboard 60 contains only a rocker switch (6, 13, 14), actuation of which causes a pulse generator (10) to increment a counter (8) connected to decoder 9. Switch (6) is also connected via a delay (11) to a pulse generator which repeatedly feeds pulses to counter (8) if the switch is held depressed for longer than a predetermined time. The indicating unit may be combined with an enciphering/deciphering unit which is basically the same as that disclosed in Swiss Patent No. 411,983; enciphering and deciphering is effected by modulo-2 mixing with signals produced by an enciphering generator 28 connected to a random number generator 120 via register 80, a gate 22; and a demultiplexer 23. In the Figs. 1- 2 embodiment, the function of generator 120 is performed by pulse generator (12) and counter (8). The output of generator 28 is applied to a mixer 26 together with input data received from keyboard 60 via demultiplexer 23, whence it can be fed back to a register 80 for subsequent display.

Title: Improvements in Apparatus for Eliminating Interference in Wireless Telegraphy.
IPC: G01S3/06
Filed: 1918-04-25
Abstract: 130,107. Marconi's Wireless Telegraph Co., and Richmond, H. April 25, 1918. Wireless telegraphy.-Wireless receiving-apparatus, adapted to prevent interference bv signals from undesired stations, comprises a pair of directive aerials ABCD, EFGH, Fig. 2, including inductances I, J and K, L respectively, which are adjustably coupled to coils P, P<1> connected in series or in parallel to the receiving-circuit. The station with which it is desired to communicate lies in the plane of one of the aerials, say ABCD, and signals from this station are transferred to the receiving-circuit by the coupling of the coils I, J to the coil P, while the signals produce no effect in the other aerial. Signals from an undesired station affect both aerials, and, by adjusting the coupling of the coils P, P<1> to the aerials, the undesired signals may be neutralized in the receiving-circuit. During normal reception, it is preferred to have a loose coupling of the coil P to the receiving-aerial ABCD, the other aerial being tightly coupled to the coil P<1>. The couplings may be so arranged that, when one is a maximum, the other is a minimum, and coupling between the inductances I, J and K, L is avoided. The aerials are tuned to the same frequency. In a modification, Fig. 1, a single coil O is placed in the field of the inductance coils I - - L, and the distance of these from the single coil is adjustable so as to produce an unsymmetrical field.
