Title: Process for the addition of maleic anhydride to polyalkylene ethers
IPC: C08G18/83
Filed: 1965-12-03
Abstract: Maleic anhydride adducts are obtained by reacting, at elevated temperatures in the presence of free radical initiators, maleic anhydride with polyalkylene ethers which have had any free hydroxy groups blocked by acylation or halogenation and whose molecular weight is higher than 400.  The reaction is suitably effected at 80-160 DEG  C. and not more that 1/2 mole of maleic anhydride is generally employed per oxygen atom of the ether group. Suitable polyalkylene ethers are polyethylene, polypropylene and polybutylene oxides and the corresponding mixed polyalkylene oxides and also the oxyalkylation products of mono-and poly-hydric alcohols, phenols and carboxylic acids as well as the products obtained from the reaction of polyalkylene oxides and oxyalkylation products with isocyanates. Specified radical initiators are diacyl peroxides, e.g. benzoyl and chlorobenzoyl peroxides, alkyl acyl peroxides, tert.-butyl perbenzoate and dialkyl peroxides, e.g. di-tert.-butyl peroxide, tert.-butyl cumyl peroxide and dicumyl peroxide.  In the examples the polyalkylene ether starting materials are diacylated.

Title: Processing fat-lime
IPC: C01F11/02
Filed: 1965-12-06
Abstract: Agglomerates of particles which occur in fat lime, that is a lime which is easily slakeable with water, are removed by heating the lime to a temperature of 30 DEG  to 150 DEG  C.  The heating step is preferably carried out in the presence of water vapour, and said water vapour is preferably super-heated.  The heating may be carried out with hot air containing water vapour and the amount of water vapour used is preferably at most that which is necessary to slake 5% by weight of the lime and most preferably only 1% by weight.  This treatment is most suitably carried out before the lime is to be used, e.g. for the manufacture of porous moulded products, or during air separation of the lime.

Title: Measuring element for dynamometers
IPC: G01L1/22
Filed: 1965-12-07
Abstract: 1,130,585. Measuring force electrically. NEDERLANDSE ORGANISATIE VOOR TOEGEPAST NATUURWETENSCHAPPELIJK ONDERZOEK TEN BEHOEVE VAN NIJVERHEID, HANDEL EN VERKEER. Dec.7, 1965 [Dec.10, 1964], No. 51849/65. Heading G1N. A dynamometer element consists of a rectangular member having two longer sides 1, Fig. 1, and two shorter, substantially rigid sides 2, the force to be measured being applied to the middle of the longer sides 5, 6, and perpendicular to them, and strain gauges 7, 8, 9, or 10, being arranged symmetrically on either side of the axis of the force, on at least one of the longer sides. At two cross-sections (II-II) on each of the longer sides 1, the bending moment due to applied force is substantially zero, and pairs of strain gauges 7, 8, or 9, 10, are arranged symmetrically on either side of these cross-sections. By connecting the two gauges of each pair in opposite arms of a Wheatstone bridge, the non linearity in measuring signal which results from shifting of the zero bending moment section with varying applied force, is reduced. The effects of thermal changes in resistance of the strain gauges are eliminated by arranging that each strain gauge, 7 or 8, on the outer face of a side 1 is situated opposite a strain gauge, 9 or 10, on the inner face of the side, opposite pairs of gauges being arranged in adjacent arms of the Wheatstone bridge. To eliminate the effects of differential expansion of the two longer sides 1 due to a temperature gradient along the axis of the applied force, the strain gauges may be arranged on portion of only one of the longer sides, the respective lines joining the centres of gravity of adjacent cross-sections of each of these portions being perpendicular to the applied force. Alternatively, the gauges may be arranged on both the longer sides, on portions thereof which are constructed symmetrically about the line joining the mid points of the two shorter sides.

Abstract: 1521321 Selective signalling SEIKOSHA KK 24 Dec 1975 [28 Dec 1974] 52778/75 Heading G4H Extra dots are inserted in a matrix decomposition of character. A character is printed in dot-matrix form using a column of print wires, with a size determined by a magnification number supplied, magnified characters requiring more than one pass of the column of wires. The character code is applied to a character generator, which is controlled to supply successive columns of the matrix decomposition to a two-dimensional shift register which can be shifted in each dimension. The column of print wires is supplied in parallel from another shift register fed serially via a gate from a particular bit position of the twodimensional shift register. A supplement detecting circuit (mainly logic) responds to stages of the two-dimensional shift register to detect particular patterns of dots and produce extra dots by providing extra pulses into the other shift register. Figs. 4, 5 show the dot patterns looked for, the extra dots being inserted where a diagonal line is shown across an empty dot position.

A plurality of double-acting hydraulic actuators 40, 47, 54, 58 Fig. 1 are supplied either singly or any one of actuators 47, 54, 58 together with actuator 40 by a single pump 25 which delivers through a supply line 27 and through a flow dividing valve 29 or through a by-pass thereof to three-position spool valves 29 1 , 29 2 , 29 3 , 29 4  which in their neutral positions shown connect the supply line 27 through by-pass passages 44, 44 2 , 44 ¢  to a return line 61, the arrangement being that on moving spool valve 29, say to the right as shown in Fig. 2 the outlet of the by-pass of the flow dividing valve 29 is blocked by a land 33 2  of a spool valve 29, whereon a first portion of the supply fluid is directed through a first axial orifice of valve 29 to a passage 39 to the space between lands 33 1 , 33 2  of valve 29, and through a line 41 leading to actuator 40 whilst the remainder of the supply fluid is passed through a second axial orifice in valve 29 to a passage 38 and through by-pass passages 44, 44 2 , 44¢ to the return line 61, and with spool valve 29 2  also actuated as shown in Fig. 4 by-pass passages 44, 44 2  are blocked by a land 34 of spool valve 29 2  and fluid from passage 38 is directed to the space between lands 34 1 , 34 2  of valve 29 2  and through a line 48 leading to actuator 47. In the event of spool valve 29, being in neutral and valve 29 2  actuated as shown in Fig. 3 no division of flow occurs at valve 29 and all the fluid from supply line 27 is directed into the space between lands 34 1 , 34 2  of valve 29 2  and thence through line 48 leading to actuator 47 which is thus actuated at a greater speed. Similarly with valves 29 1 , 29 2 , in neutral and either valve 29 3  or 29 4  actuated, all the pump delivery is passed either to motor 54 or 58. Actuation of spool valves 29 1  --- 29 4  to the left results in reverse stroke of its associated motor.

Title: Burst synchronization method and apparatus
IPC: H04B7/15
Filed: 1969-10-30
Abstract: 1293800 Satellite communication system POST OFFICE 30 Oct 1969 [30 Oct 1968] 53331/69 Heading H4L The burst transmission time of an earth station allotted a slot in a time-division multiple access satellite communication system is adjusted in accordance with calculated preductions based on a number of previous adjustments and the resulting phase errors relative to transmissions from a reference station as measured on the re-transmitted signals received from the satellite. Identifying code signals for the reference station and the particular earth station are detected and apply timing signals to lines 76 and 78 respectively, and these are gated by 30 at 200 millisecond intervals and applied to set and reset inputs of bi-stable circuit 32. Thus counter 38 receives from reference oscillator 36 pulses representing the actual interval between the reference and station signals, and the count is compared with the contents of 44 which represents the desired interval. The difference from 42 is added to the current correction held in counter 54 and supplied to data processor 58. Processor 58 stores six such values (each of which represents the correction which would have reduced the phase error to zero) and predicts, on the basis of a linear function calculated as a best fit to these six values, the required correction for the next transmission burst. The current correction in 54 is subtracted from this and the result used to update the count in 54. Counter 48 receiving pulses from oscillator 36 passes through a complete cycle in one frame, and when its count corresponds to that in 54 a signal is generated in 52 to initiate the transmission burst.

Abstract: 1,166,827. Making coils. ENGLISH ELECTRIC CO. Ltd. 20 Dec., 1966 [21 Dec., 1965], No. 54107/65. Heading B3A. [Also in Divisions H1 and H3] An inductive device, e.g. a transductor, comprises a plurality of toroidal core sections 13-17 spaced by members 20-23 extending outside the core to restrain the outer limbs of preformed U-shaped conductors 34 straddling the core and joined to form the winding. Spirally wound or transverse laminated core sections are bolted together with insulating boards 20- 25 and insulated copper conductors threaded through holes in the boards outside the core. An insulating tube 32 is forced within the core to wedge the inner limbs of the conductors against the boards and the assembly located via spacers (33), Fig. 2 (not shown), over a hollow conductor 12 whose inductive impedance is to be controlled. The conductors are brazed together to form a control (36) and bias winding (37), each consisting of two parallel-connected sections, to vary the core saturation. Alternatively, the conductors may be connected in parallel, or in parallel-connected pairs connected in series.

Filed: 1973-11-22
Abstract: 1455869 Utilizing radiation detectors ISOTOPCENTRALEN 22 Nov 1973 [22 Nov 1972] 54177/73 Heading G1A The amount of a chemical in a sample is determined by combined back-scatter and transmission measurements. In Fig. 1 a primary radiation source 3 transmits radiation to a sample in region 10; back-scattered radiation strikes scintillator 5 which is shielded from source 3 by  material 4. Radiation which passes through the sample is reflected back by plate 9 through the sample again to strike the scintillator. The scintillator output can be made largely independent of sample density as a result of the two types of measuring provided the dimensions of the apparatus and sample, and the source collimation are suitably chosen. For measuring sulphur in oil the souce is Am 241 which emits γ rays; the radiation is reduced to 22 keV by a silver sheet. The reflector is of molybdenum and it produces x-rays which return through the sample to the scintillator. If desired  the scintillator detector circuitry may be such as to distinguish between back-scattered γ rays and secondary x-rays from the reflector. Lead in petrol can be meausred, as can two phase slurries. Two or more primary souces can be used, and the reflector can be replaced by an active secondary source.
