Title: Polythiodiethanol millable gums
IPC: C08L71/02
Filed: 1975-12-03
Abstract: 1513010 Sulphur - containing polymers AMERICAN CYANAMID CO 3 Dec 1975 [19 Dec 1974] 49650/75 Heading C3R An elastomeric copolymer of formula is obtained by reacting a diepoxide containing radical R with the terminal -OH groups of a polythioether polyol of formula where -(-OG-)- represents randomly alternating units (i) derived from thiodiethanol and units (iv) derived from an aliphatic diol that provides unsaturation in the polymer chain in such a manner that is it possible to pass from one end of the chain to the other without traversing the allylic structure. Also in -(-OG-)- there may be units (ii) -(-OR<1>-)- and (iii) -(-OR<11>-)- derived from aliphatic and aromatic diols, respectively. The ratio of units (i) to the total of units (ii), (iii) and (iv) is greater than 1 : 1, (ii) and (iii) being optional, and the content of units (iv) is from 1 to 10 mole per cent of the total mole content of -(-OG-)-. In the polymer x is an integer such that the Mooney value of the polythioether polyol is less than 20 and n is an integer such that the Mooney value of the copolymer is higher than the Mooney value of the polythioether polyol, thus enabling the elastomer to be processed on a rubber-mill. In examples polythioether polyols are obtained by reacting thiodiethanol with 4,4<1>-isopropylidenebisphenol and 3-cyclohexene-1,1-dimethanol, with the monoallyl ether of 2-ethyl-2- (hydroxymethyl)-1,3-propane diol and 4,4<1>. isopropylidene-bisphenol, with the monoallyl ether of 2-ethyl-2-hydroxymethyl)-1,3-propane. diol and with 3 - cyclohexene - 1,1 - dimethanol; the polythioether polyols are then extended by reaction with the diglycidyl ether of 4,4<1> - isopropylidenebisphenol, with the diglycidyl ether of 1,4-butanediol, with dicyclopentadiene diepoxide and with diglycidyl ether.

Title: Electric pulse generator
IPC: H03K3/33
Filed: 1963-12-17
Abstract: 1,062,040. Semi-conductor pulse circuits. GENERAL ELECTRIC CO. Dec. 17, 1963 [Dec. 26, 1962 (2)], No. 49837/63. Heading H3T. A pulse generator comprises a pair of oppositely poled charge storage diodes 18, 32 (Fig. 4) fed with oppositely poled signals so as to produce output voltages having steep leading edges, the output voltages being combined so that the leading edge of the voltage from one diode forms the leading edge of an output pulse, while that from the other diode forms the trailing edge of the output pulse. As shown in Fig. 4, the circuit is fed with a 43 Mc/s. pulses or sine wave from a source 10 to the charge storage diodes 18, 32 via transmission lines correctly terminated by resistors 25, 42 and tuned circuits 23, 26; 37, 43. A 180 degrees delay 16 is included so that the diodes 18, 32 operate on signals of opposite polarity. Diode 18 becomes conductive during positive half-cycles and remains conductive during part of the negative half-cycles because of charge storage, the impedance increasing abruptly when the return flow of injected minority carriers ceases. A similar abrupt increase in impedance is exhibited at a slightly different time by diode 32, the waveforms from the two diodes being combined in a transmission line 45 and clipped by a reversed tunnel diode 49 (referred to as a back diode) giving a pulse at 52, the leading and trailing edges of which correspond to the abrupt changes in impedance of the diodes 18, 32. The duration of output pulse may be adjusted by variation of the bias supplied by potentiometers 54, 55 to diodes 18, 32. The potentiometers 54, 55 may be ganged in opposition so that the pulse duration may be adjusted without affecting the timing of the mid-point of the pulse. A pulse of reverse polarity may be obtained by adjusting potentiometers 54, 55 so that diodes 18, 32 operate in reverse order. Alternatively, the pulse duration may be adjusted by variation of the delay at 16. Resistors may be connected in series with or may replace transmission line 45. Fig. 5 shows a pulse generator in which the charged storage diodes 18, 32 are connected in shunt. Differentiating capacitors 67, 70 respectively pass only the voltage steps due to the abrupt change in impedance of diodes 18, 32, the first differentiated pulse setting a tunnel diode bi-stable circuit 57 so as to initiate an output pulse at 52, the tunnel diode being reset by the differentiated pulse from diode 32 so as to terminate the pulse at 52. The invention can provide pulses of duration 0À4-3 nS at 40- 630 Mc/s. having amplitudes of 3-20V. Modifications, Fig. 1 (not shown), relates to a circuit similar to Fig. 4 but using shunt charge storage diodes. Fig. 8 (not shown) corresponds to Fig. 5 but uses series diodes.

Abstract: 1,171,136. Sawing. A. G. BODINE. 8 Nov., 1966, No. 49949/66. Heading B5L. [Also in Divisions E1 and F2] Apparatus for driving a stem (e.g. a ground anchor) into the ground (see Division E1) ineludes a sleeve 35 which is vibrated longitudinally. The anchor shown comprises a plate 33 to which is pivoted at 31 a rod which extends up the sleeve 35. When the plate 33 has been inserted edgeways into the ground to the required depth, the rod is brought normal to the plate by simultaneously vibrating the sleeve axially, rotating the sleeve about its axis and pivoting it about the point 31. The sleeve thereby forms a trench t the vibratory movement of the sleeve causing the earth in the trench to fluidize and flow past the sleeve so that the earth remains in the trench throughout the process.

In an alternative arrangement, only the leading head illumination is switched. The heads comprise optical fibres 42, 46 which lead to either separate photo detectors, or, as shown in Figs. 1 and 2, a common detector 20. Optical fibres 50, 60 lead to separate lamps 54, 58. The photo detector output is detected by detector 66 which operates a latch 50 connected to scanning speed controller 40 and lamp drive circuits 52, 56. A counter 64, which is supplied by a clock 62 synchronized with the rotation of the document drum 12, is reset to zero by detector 66 in response to detection of data and functions to change-over the latch for fast scanning when data ceases to be detected, the delay in change-over depending on the count which is chosen appropriately.
