Title: Improvements in or relating to the manufacture of goods of rubber or similar material
IPC: C08L7/00
Filed: 1931-02-20
Abstract: Compositions having physical properties similar to those of guttapercha or leather are produced by the consolidation of granular dispersions of rubber or the like to which have been added thermoplastic materials, such as carnauba wax, synthetic waxes, shellac, rosin and synthetic resins, polyvinyl esters, bitumen and mineral waxes.  The granular dispersions are obtained by effecting the coagulation of aqueous dispersions by precipitation in situ of compounding ingredients formed by the double decomposition of water soluble reagents having normally no coagulating effect with subsequently added water soluble reagents an ion of which may incidentally possess coagulating influence. Examples of suitable reagents are given.  If desired the granular dispersions may contain also fibrous or divided materials such as leather fibre, asbestos fibre, wood pulp, wood flour, jute fibre, cotton flock, paper pulp, abrasives and cork.  The shells of gold balls may be formed from such dispersions by moulding the dry sheeting obtained after consolidation or the deposit obtained by immersing a hemispherical filter mould in the dispersion and applying suction, or the dispersion may be applied directly to the core of the golf ball in a pasty condition. Specifications 219,365 and 290,313, [both in Class 70, Indiarubber &c.], are referred to.

Title: Amplifiers with a signal clipping indicator and/or protective circuit
IPC: H03F1/52
Filed: 1974-02-08
Abstract: 1458857 Transistor amplifying circuits SONY CORP 8 Feb 1974 [9 Feb 1973] 05898/74 Heading H3T An amplifier with a signal clipping indicator and/or protective circuit is provided with negative feedback and means for detecting a predetermined amplitude change of the output signal by comparison of the input and output signals whereby there is produced a control signal when the output waveform is clipped and which is indicative thereof. Input signal at terminal 1 is applied to the base of transistor 6a in long-tailed pair 6a, 6b which has transistor 6c as common emitter impedance: potentiometer 25 is for adjusting the D.C. level in the final output. Long-tailed pair 6a, 6b drives a second long-tailed pair 9a, 9b which in turn drives a third pair 10a, 10b. From the collector circuit of transistor 10b there is driven an output stage comprising the complementary Darlington pairs 11a, 11b and 12a, 12b respectively. Negative feedback is applied from the output terminal 2 to the base of the transistor 6b, by means of resistors 7, 8. When either an excessive input signal is applied to terminal 1 causing the output and consequently the feedback signal to be clipped, or the output terminal 2 becomes earthed, an increased output is obtained from the transistors 6a, 6b which causes the transistors 9a, 9b to be overdriven: their collector potentials are then driven into the negative region in which diodes 36, 37 conduct. Transistor 18, which is normally conductive, is then driven non-conductive, whereby the normally non-conductive transistor 17 is driven conductive. This causes the monostable circuit comprising transistors 15a, 15b, in which the former is normally conductive, to momentarily reverse its state. Transistor 15b then becomes conductive and an electroluminescent diode 16b in its collector circuit is illuminated and provides a warning. In a second embodiment a relay coil is provided in series with the electroluminescent diode, and causes the amplifier output to be open-circuited in fault conditions (Fig. 2, not shown). Alternatively the signal applied to input terminal 1 may be muted or the operation of the output transistors stopped.

To read the stored information, addressing transistors 6, 8 are turned off and on respectively by signals applied to their bases to turn on transistor 1 and current generator 5 supplies its lower level of current so that read device 10 receives, for an interrupted fuse a current equal to the sum of the currents from generators 4, 5 and for an uninterrupted fuse the sum of the current from generator 4 and the base current of transistor 1 (the latter being the current from generator 5 divided by the gain B of the transistor 1). Each row conductor is connected to the emitter of an associated voltage limiting transistor (26, Fig. 3, not shown), the bases of which are connected to a common constant voltage generator (28). Each column conductor is connected to the emitter of an associated reference voltage transistor (21), the base of which is connected to constant voltage generator (32) and the collector of which is earthed. In a modification (Fig. 4, not shown) the columns of the matrix are arranged in groups with one voltage limiting transistor (3) and one constant current generator (4) for each row in each group.
