Abstract: 1,224,699. Continuous production of foamed profiles. A. SCHAERER. 14 Nov., 1969 [20 Nov., 1968], No. 55887/69. Heading B5A. Foamed profiles of cross-linked resins are continuously formed by introducing a carrier foil 5 into an open-topped carrier section 1, filling the foil with foamable resin from a mixing head 8, moving a covering section 12 over the open top of the carrier section 1 so that the expanding mix fills the section and forces the foil 5 against the walls and maintaining the carrier section 1 and covering section 12 in contact while the resin cross-links. The profile is then removed from the mould and the foam and carrier foil may be separated. The carrier section preferably comprises elongated channel members which are removably joined end to end, but a batch process may be performed in channels with closed ends. The carrier foil 5 may be a metal foil or sheet, an impregnated plastic web or a thermoplastic foil and may be a multilayer laminated foil or have an outer layer of polyvinyl fluoride and an inner layer of non- woven glass fibre. The foil is folded to the shape of the carrier at 6, before it enters the channel and is preferably of the form shown in Fig. 3 having a top flap 9 which together with the side walls completely encloses the formed resin and forms with the side wall a flap through which air escapes as the resin foams. Alternatively the top flap may be attached to the covering section 12 and may not contact the foil 5, the intermediate mould walls being coated with release agent in this case. Reinforcements such as perforated metal strips or impregnated paper board strips may be placed into the carrier foil before the resin is introduced. The covering section 12 is maintained in contact with the carrier section 1 until the resin cross-links by passing both sections between belts 13, 14 running on rollers 26, 27. The foam is preferably polyurethane and may contain foamed glass or foamed clay beads as filler.

Abstract: 1373132 Transistor amplifying circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 6 Dec 1971 [9 Dec 1970] 56518/71 Heading H3T [Also in Divisions G3 and G4]  A current divider comprises a number of circuit branches carrying currents bearing fixed integral ratios to each other. The branches are all connected to a sum terminal, and include transistors which pass integrally related emitter currents when provided with equal base-emitter voltages. Current deviations caused by transistor base currents, are compensated by supplying to or deriving from each branch a current which is an integral multiple of the base current. In the circuit of Fig. 1, five identical transistors T 1 -T 5  have parallel-connected baseemitter paths and therefore accurately equal emitter currents I. However, the collector currents will differ by multiples of the base current Ib. To compensate for this, a further identical transistor S 1  is included and connected so that to first order in Ib, the current at input A is equal to I, the current at output terminal B is 4I, and the current at sum terminal C is 5I. Similar circuits using more terminals and cascade arrangements to give required current ratios are described, Figs. 2-7 (not shown). Such circuits may be used in D-A converters and decade counters, Fig. 8 (not shown), and also in a current regulator, Fig. 9 (not shown), in which a resistor is used to adjust the current level independently of the supply voltage.

The flexible members are apertured for the passage of fluid, the apertures being closable by contact with the face of the adjacent member or plate. In one embodiment, Fig. 3, flexible members 3, 4 are sandwiched between plates 1, 2, plate 1 being domed to allow the part 11 of member 3 to move upwards when fluid is admitted to aperture 9, fluid then flowing via aperture 13 and dome 8 to outlet aperture 10. Part 11 prevents flow from aperture 10 to aperture 9. A fluidic OR gate, Fig. 4, comprises of three flexible members. The output signal S represents the logical function (a + b). In a further embodiment, Figs. 5 and 6, one of the members 27 has upstanding parts 35, 36, and members 25, 26 separated by a rigid plate 37. The element can act as an inverter, a bistable settable to one state or the other by a signal on a respective input, an AND gate, or a NOR gate. Fig. 5 shows the element in one state in which chamber 28 is in communication with aperture 29. Fig. 6 shows it in the state in which chamber 28 communicates with aperture 34 via aperture 30 and the gap formed between members 25, 26 by plate 37 when diaphragm 32 is in its raised position. Embodiments generally similar to that disclosed in Figs. 5 and 6 are described. The logic elements may be interconnected to perform a required function, and the laminar members and plates may be common to the elements, so providing a functional module. Such a function may be that of a bi-stable unit which is switched from one state to the other by successive pulses on the same input, the output signal being maintained when the input pulse ceases, Fig. 12a-12d (not shown). Another function is that of an EXCL-OR gate, Fig. 13 (not shown).

Abstract: 1369442 Fault-indicating systems JOSEPH LUCAS (INDUSTRIES) Ltd 6 Dec 1971 [22 Dec 1970] 60745/70 Heading G4H In a fault indicating system the operational condition of a plurality of D.C.-operated devices 12, 12a, is determined during an interrogation cycle comprising a transmission period in which an oscillator 18 in a monitoring unit 18-21 sends an address signal to fault indicating circuits 23-27 connected to each device 12, and a plurality of receiving periods during each of which a respective circuit sends back to the unit a reporting signal whose position within its respective period is indicative of the operating condition of the corresponding device. Receipt by the unit of a signal in the first or second half of its receiving period respectively indicates satisfactory operation of the device or the need for attention, and the absence of a signal in both halves indicates failure of the device; alternatively, a two-state signal may be used to indi cate whether or not the device is functioning. The address signal is a pulse train of predetermined frequency and length; on receipt of this signal a detector 23 activates an answer unit 26 via delay unit 24 which introduces a delay representative of the device. The output signal from 26 is fed through unit 24 again and is subject to a further delay which is determined by a condition monitoring unit 27 connected to the device 12; this doubly delayed signal is fed to a detector 19 in unit 18-21 and is used by a correlator 20 to activate display and warning devices 21. In one embodiment, 26 is a gate which is opened after the count-down of a counter 24 from a value which is indicative of the device 12 and of its operating condition, the opening of the gate allowing a pulse train from an oscillator 25 to be fed to detector 19: here gates (one for each device) are sequentially enabled (at the beginning of each receiving period), the delay before the arrival of the respective pulse train providing the required information about the condition of the device.
