Title: Diisocyanato diphenylmethane derivatives and their polyurethane products
Inventor: LAMBERT ARTHUR
IPC: B01D19/00
Filed: 1958-01-22
Abstract: Diisocyanato-diphenyl-methane derivatives of formula: <FORM:0852651/IV(a)/1> where the R's are the same or different C1-C4 alkyl radicals, are used as intermediates for the production of polyurethanes.  They have a very low reactivity towards hydroxyl groups at atmospheric temperatures but ready reactivity at elevated temperatures.  They may be used in conjunction with polyhydroxy compounds in the production of surface coatings and lacquers, particularly in compositions which are to be heat-cured. They may be used in the production of polyurethane products which are homogeneous or cellular, rigid or flexible, or in the form of coatings or adhesives, or used in potting compounds for electrical components. The isocyanates may be used as such or may first be converted into trimeric or other polymeric form e.g. by the use of basic catalysts. In an example, a polyesteramide, obtained by condensing adipic acid with ethylene glycol, diethylene glycol, and ethanolamine is modified by reaction with a mixture of tolylene -2 : 4- and -2 : 6- diisocyanates, and the product is milled with 4 : 41-diisocyanato-3 : 31 : 5 : 51-tetra-methyl diphenylmethane and heated under pressure in a mould.  An elastomeric polyurethane is obtained. Specification 779,806 is referred to.ALSO:The invention comprises compounds of the formula:  <FORM:0852651/IV(b)/1> where the R's are the same or different C1-C4 alkyl radicals.  The compounds may be prepared by the phosgenation of the corresponding diaminodiphenyl methane derivatives which may themselves be obtained by reaction of 2:6-dialkyl anilines with formaldehyde in the presence of hydrochloric acid in aqueous medium.  Diamino-diphenylmethane derivatives containing C2-C4 alkyl substituents may be made from lesser substituted derivatives by reaction with alkenes in presence of aluminium, e.g. 4:41-diamino-3:31:5:51-tetraethyl diphenylmethane may be made by reaction of 4:41-diamino diphenylmethane with ethylene in presence of aluminium.  The phosgenation may be effected by heating the diamino compound with phosgene at above 120 DEG C. optionally in presence of an inert diluent.  The initial mixing of the reagents may take place at a low temperature, e.g. 0 DEG C.  Specification 779,806 is referred to.

Title: Improved mechanism for automatically operating typewriters
IPC: B41J5/38
Filed: 1922-01-26
Abstract: 174,924. Pillings, J. H. Feb. 7, 1921, [Convention date]. Strip - controlled driving mechanism. - The mechanism comprises rocking feelers controlling movable plates connected to the key-levers; on engaging a perforation, one of the feelers rocks and moves a plate into the path of a driving- member, whereupon the plate descends to operate the associated lever and restore' the feeler. In the mechanism shown in Figs. 1 and 2, the key-levers 14 are connected by links 18 to plates 20, which are guided by combs 30, 31 and are formed with inclined slots 24 engaging fingers 27 on rocking feelers 26, fulcrumed on a shaft 33 and guided by a comb 36. The strip C passes over a stationary support 15 formed at the top with slots 17, or a continuous groove or slot, the strip being fed by sprocket-wheels 12 on a shaft 10 driven by worm gearing 61, 62. When the nose 26<a> of a feeler meets a perforation, the feeler is rocked by a spring 34, the nose passing through a perforation c in the strip, and the associated plate 20 is moved forwards into the path of a reciprocating driving-bar 41, which thereupon depresses the plate. In descending, the plate operates the key-lever and, by means of a slot 24, rocks the feeler and releases the nose from the perforation, such release being effected before the rear end of a perforation reaches the nose. When the bar rises, the plate is lifted by a spring 50, the movement being limited by a strip 52, and the nose of the feeler drops on to the strip. A projection 20<b> on the plate co-operates with the comb to prevent rearwards movement of the plate until it has descended and returned almost to the normal position. The driving-bar may be carried by arms 42 secured to a rock-shaft 43 provided with a slotted arm 44 engaging a cam 46 on the driving-shaft 60. The feelers can be raised, to facilitate insertion of the strip, by means of a rocking-bar 61<a> adapted to engage arms 28 of the feelers.

Title: Improvements in or relating to detector circuit arrangements
IPC: H03D3/14
Filed: 1957-01-25
Abstract: 858,310. Frequency discriminators. PHILIPS ELECTRICAL INDUSTRIES Ltd. Jan. 25, 1957 [Jan. 28, 1956], No. 2765/57. Class 40(5). In a frequency discriminator a pair of transistors are controlled by currents which change in phase with the frequency deviation the transistors having a common load circuit. The load circuit current is held constant by a third transistor in series with the supply and controlled in accordance with the mean amplitude of the F.M. signal so as to reduce the effects of amplitude modulation. The signal to be detected is fed to two approximately critically coupled networks 3, 4, which provide the base/emitter currents of grounded emitter transistors 1, 2 having a common supply and a common load resistor (and by-pass capacitor) 6. The duration of the load current varies with the relative phase difference between the voltages across circuits 3 and 4. The amplitude of the current is maintained substantially constant by the inclusion of transistor 7 and its emitter resistor 5 in the supply circuit as the voltage drop across resistor 5 cannot exceed the base voltage of transistor 7 and this voltage is substantially constant and proportional to the mean amplitude of the signal applied to circuit 3. This voltage is derived from a rectifier 8 and capacitor 10 which with resistor 11 acts as a dynamic limiter by varying the damping across circuit 3, and also supplies, after further filtering (at 9) both the control voltage for the transistor 7, and an A.G.C. voltage for use eleswhere in the receiver. In a second embodiment, Fig. 2, a single tuned circuit 19, 20 is used, the circuit current passing through the base/emitter path of transistor 1 (shunted by oppositely poled rectifier 22 to prevent rectification taking place) whilst a portion of the tuned circuit voltage supplies the base/emitter current of transistor 2. The mean -circuit amplitude is again detected at 8 and used to control the current regulating transistor 7. Amplitude modulation is further reduced by a resistor 25 decoupled for signal frequencies in the base circuit of transistor 2. A voltage proportional to amplitude is produced across this resistor by base rectification in the transistor 2 and the resulting bias, by reducing the conductive period of the transistor with increasing signal amplitude, offsets the increase in load current duration due to the increasing steepness of the input waveform. As an alternative this effect may be compensated by utilising the abrupt variation in the base current of the transistor 7 when the transistors 1 and 2 become conductive, by making resistor 12 comparitively high and capacitor 13 low. In a modification, Fig. 3, (not shown) the above effect is compensated by deriving a second voltage from the detector 8, 9 of opposite polarity to the first and having a shorter time constant so as to follow the amplitude variations, and applying this second voltage to the base of transistor 7 in addition to the first.
