Patent GB-1296750-A (GB)
IPC: H03F3/343
Filed: 1970-07-20
Abstract: 1296750 Transistor amplifiers PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 20 July 1970 [23 July 1969] 34975/70 Heading H3T A difference amplifier has a first pair of terminals i connected to the bases of a first pair of transistors 1, 2 which have their emitters connected to the bases of emitter coupled second pair of transistors 3 and 4 and a second pair of terminals connected to the collector load impedances R and to one of the pairs of terminals is applied a compensation voltage which contains in a compensating sense, the error voltage due to a difference between the current amplification factors of the transistors 3, 4 and which is obtained by the reproduction of the base-emitter voltages of at least the first pair of transistors 1, 2 in the P-N junction of semi-conductor elements 7, 8 respectively traversed by the collector currents of the first pair of transistors 1. 2. Any difference between the current amplification factors of the output transistors 3, 4 (due to manufacture and dependent on temperature and time) in the absence of an input signal causes the base-emitter voltages of the input transistors 1, 2 to be different. In order to compensate for this unsymmetrical arrangement to provide zero output when no signal is applied an error signal is applied to the output input of the difference amplifier. The base-emitter voltages of transistors 9 and 10 (Fig. 2) are arranged to equal those of transistor 3 and 4 and the baseemitter voltages of transistors 7 and 8, which are connected as diodes, are arranged to equal those of transistors 1 and 2. The compensation error voltage is applied via transistors 5 and 6, the collector load pR of which may be zero. A number of transistors connected as diodes in the pass direction may be connected between the emitter of transistor 10 and the collector of transistor 4 and with the same number connected between the collectors of transistors 4 and 7 so as to enable the base current of transis. tor 5 to be increased. A similar transistor connection may be applied to transistor 6. In a modification (Fig. 3, not shown), the transistors 9 and 10 are removed and transistors connected as diodes may be included in the collector circuits of transistors 1 and 2. In a further embodiment (Fig. 4) the error voltage is applied to the input transistors 1 and 2. The capacitors and resistors shown dotted may be provided for use at higher frequencies. In a modification (Fig. 5, not shown), the transistors 9 and 10-are removed. In a further modification (Fig. 6, not shown), using all NPN transistors, the emitters of the transistors 5 and 6 are connected to the base electrodes of transistors 1 and 2 and the base electrodes of transistors 5 and 6 are fed from the emitter electrodes of the transistors 8 and 7. This cross-coupling may be applied to the circuit of (Fig. 5, not shown). The amplifier may be constructed in integrated circuit form.

Abstract: 1297551 Phenolic foam laminate DYNAMIT NOBEL AG 22 June 1970 [23 June 1969] 30279/70 Heading B5N [Also in Division D1] A phenolic resin is adhered to a fibrous layer by foaming in contact therewith and the fibrous layer is subsequently impregnated with either (1) tarry or bituminous material, (2) a thermoplastic polymer or copolymer of ethylenically unsaturated monomers, or (3) a phenol-aldehyde condensate, the foam and impregnant then being dried. The surface layer may be pasteboard, soda paper, or a woven or non-woven fabric. The phenolic foam can be introduced as a foamable mixture containing blowing agent and hardener, between two surface webs and foamed and hardened in a double belt press at 60-80 C. Alternatively, it can be foamed in a mould lined with a surface layer. The impregnant is a solution, dispersion, emulsion, or melt. It may be applied by dipping, coating, or spraying at 20-100 C. The tarry material may be obtained by the dry distillation of coal, lignite, peat or wood. The bituminous material may be obtained by refining petroleum having a molecular weight of from 300 to 3000. The polymer may be a vinyl, acrylic, methacrylic, or ethacrylic polymer of molecular weight 10,000 to 60,000. The phenolic resin impregnant may be obtained by the alkaline condensation of a phenol, optionally alkylated, and an aldehyde (as may the phenolic foam).

Abstract: 1321229 Injection moulding A BRAMLEY 3 Aug 1970 [6 Aug 1969] 39461/69 Heading B5A [Also in Division D1] A net is formed by repeated cycles of drawing at least one transverse thread T across an array of warp threads L, and injecting molten thermoplastics material into dies formed about the junctions. The dies are formed by the union of upper cavities 18, which are connected with injectors 21, and which are mounted on an upper carriage (13a, Fig. 1, not shown), and lower cavities 41, mounted on a lower carriage (13b). Thread T is drawn across by means of a chain (50) and gripper (51) Fig. 2 (not shown), and the upper and lower carriages moved vertically towards each other. Thread T is loosely gripped by elements 26, 44, which allow the thread to be displaced slightly by diverter elements 30. This allows for the contraction of threads T when molten material is injected about the junctions. The displacement of elements 30 may be adjusted by means of screw thread 31. The displacing surface of element 30 is convex, with radial grooves 34, two of which serve to guide threads T, grooves (42) in the blocks carrying the lower cavities also guide threads T, whilst grooves (25) in the upper carriage guide warp threads L. Blade 27 is lowered to cut thread T before the junctions are bonded with injected material. The carriages are then moved longitudinally, ready for the laying of another transverse thread.
