Patent GB-1205722-A (GB)
Title: System for transmitting signals in groups (blocks)
Inventor: VAN-DUUREN HENDRIK CORNELIS AN
IPC: H04L1/00
Filed: 1969-01-09
Abstract: 1,205,722. Digital transmission systems. NETHERLANDS POSTAL & TELECOMMUNICATION SERVICE, DIRECTOR GENERAL OF. 9 Jan.. 1969 [19 Jan., 1968], No. 1310/69. Heading H4P. In a digital transmission system in which date is sent in blocks of n-bit words, each block consists of two data words, in an error-detecting code, followed by a check word formed by modulo-2 addition of corresponding bits in the data words. At the receiver, if error is detected in only one data word the correct word is derived by modulo-2 addition of the correctly received word and the check word. Transmitter.-Two 5-bit words from a tape store are converted to 7-bit constant ratio words. The first word, e.g. K1, is placed in a 7-bit register A-G, Fig. I (not shown), whose serial output is connected to a second register AA-GG and to a modulo-2 adder. The output of the second register is connected to the transmission channel and to the second input of the adder. The adder output is fed to the first stage A of the first register A-G. When the registers are shifted the content of the second register is transmitted and also added to K1. At the end of shifting, K1 is in register AA-GG, and the sum is in register A-G. Register A-G is now cleared and the second word K2 read in to it. Upon further shifting, K1 is transmitted, the sum K1 + K2, which is the check word, appears in register A-G, and K2 appears in AA-GG. In the next shifting period K2 is transmitted and the check word passes to register AA-GG. The first word K3 of the next block now replaces the content of A-G and, upon shifting, the check word is transmitted, the cycle then repeating. Receiver.-The first and second words K1, K2 are passed to respective registers SRI, SRII, Fig. 2 (not shown), and are also passed to a unit which, by checking the bit ratio, determines whether either word is faulty. If one word is faulty it is cleared from its register. The registers are interconnected by modulo-2 adders which are also fed with the check word so that the correctly-received word can be added to the check word. The sum, which is the correct form of the mutilated word, is placed in the cleared register. When both registers contain correct words they are read out in parallel to units which convert the 7-bit words to 5-bit words, the latter being stored in serially connected 7-bit registers wherein Start and Stop bits are added prior to reading the words serially by bit to a printer.

Title: Power remaining indicator
IPC: G06G7/70
Filed: 1964-01-15
Abstract: 997,698. Measuring residual power electrically. UNITED AIRCRAFT CORPORATION. Jan. 15, 1964 [Feb. 4, 1963], No. 1739/64. Headings G1N and G1U. [Also in Division H3] Apparatus for indicating the residual power in a gas generator for e.g. the turbine of a helicopter, comprises means for comparing various engine parameters with their limiting values, and feeding the differences in parallel to a meter through a circuit which only allows the minimum difference to be indicated. As shown (Fig. 2), the gas generater discharge temperature is measured at 10 by e.g. a thermocouple, and compared at 12 with a reference temperature signal from 14. The difference is modified at 18 by the gas inlet temperature measured at 16 by e.g. temperature-sensitive resistors, amplified at 36, and compared at 42 with a predetermined voltage, the difference signal being inversely proportional to the residual power in accordance with the permissible temperature rise in the generator discharge tube. In similar manner the turbine torque is measured at 20 to produce a signal indicative of the residual torque, and the gas generator speed is measured at 26 to produce a signal indicative of the residual power in accordance with permissible speed rise. The three residual power signals are fed to transistors 52, 54, 56 (Fig. 3) in a power limit selector 50, and the amplifier signals are taken through diodes 58, 60, 62 to a meter 64, whereby the largest of the three is conducted through its diode to be indicated on meter 64, whilst it reverse biases the other diodes and blocks them. Thus the appropriate transistor only is allowed to conduct, and a lamp 72, 74 or 76 indicates which parameter is nearest its limiting value, whilst meter 64 indicates how near. Diode 78 provides automatic temperature compensation for diodes 58, 60, 62.

Title: Improvements in or relating to radiant heaters
IPC: F24C3/14
Filed: 1963-01-15
Abstract: A flameless combustion element for a radiant heater comprises discrete, amorphous, inorganic, ceramic fibres formed into a homogeneous porous wall structure about a wire screen and inorganic refractory rigidifying means mechanically linking the fibres at their cross-overs, the fibres on the outer surface of the wall being capable of incandescing.  The fibres may be made of a mixture mainly composed of alumina and silica, or quartz or vitreous silica.  The rigidifying means is a coating of alpha alumina or a mixture of gamma alumina and theta alumina.  The element is made by immersing the chopped fibres in a tank containing aluminium nitrate or chloride and/or colloidal alumina and methyl cellulose; methyl methacrylate or camphor or menthol is then added; platinum and palladium may be added; the solution is then agitated in a moulding tank and the wire screen immersed therein.  A pump is used to suck the solution through the screen and to deposit the fibrous slurry thereon.  The screen is then removed, dried and heated in a kiln the temperature of which increases from 150  DEG F. to 1100  DEG F.  The methyl methacrylate sublimes to leave the wall porous and the aluminium nitrate is reduced to alpha or a mixture of gamma and theta alumina depending on the final temperature.  In addition to aluminium compounds, compounds of zirconium, beryllium, thorium, cobalt, hafnium, barium, magnesium and strontium may be used.

Title: A process for the separation of mixtures of oily or waxy substances according to thecountercurrent principle
IPC: C10G73/06
Filed: 1935-01-19
Abstract: In processes for the separation of fatty acids, paraffin wax from paraffin oil, and similar oily or waxy mixtures in stages in countercurrent, the material introduced in each separation stage has a composition intermediate between the average of the compositions passing to and from the stage to the next succeeding stage and the average of the compositions passing to and from the stage to the next preceding stage.  The average of the compositions is that obtained by mixing equal weights.  The separation is effected by methods which involve the production of a solid and a liquid phase and the stages may be of the same or of different character, e.g. recrystallization from solvents or pressing at different temperatures.  The Specification as open to inspection under Sect. 91 gives formul which enable the costs of the different stages and methods of separation to be taken into account in calculating the condition as regards the composition of the material to be treated in the various stages, and the minimum amount of material which needs to be treated to obtain a definite amount of the end products.  This subject-matter does not appear in the Specification as accepted.
