Patent GB-1226403-A (GB)
IPC: D21J5/00
Filed: 1968-04-18
Abstract: 1,226,403. Moulding fibrous pulp articles. AMF Inc. 18 April, 1968 [15 May, 1967], No. 18396/68. Heading B5A. [Also in Divisions B1-B2] In the method of moulding by accreting pulp from a slurry on to a foraminous former 44, Fig. 1, the former is located in a receptacle 30 and its interior is connected to a source of vacuum while the pulp slurry is supplied to the receptacle so that the fibrous material of the slurry builds up on the outside of the former which is surrounded by a baffle member. The discharge into the receptacle 30 has a substantially annular pattern. The fibrous content of the slurry may be varied during an operating cycle so that the article varies in degree of coarseness or density across its thickness, the changes in coarseness being abrupt or gradual to give a desired pattern. In the making of, for example, a cylindrical filter body, the slurry is fed to the receptacle 30 from two interconnected tanks 16, 20 which receive coarse and fine fibrous stock from supplies 10, 12 through control valves 14, 18. Valves 72, 74, 76 control the supply of slurry compatible fluid e.g. water to the receptacle 30 and tanks 16, 20. The discharge from the tanks is controlled by valves 24, 25, 24<SP>1</SP>, 25<SP>1</SP>. Probes are used to detect pulp and liquid levels in the tanks 16, 20 and receptacle 30 and the levels are controlled accordingly. An arrangement involving three supplies of fibrous stock is also described and examples of stock composition are given.

Abstract: 1,226,673. Integrated circuits. TEXAS INSTRUMENTS Inc. 27 June, 1968 [3 July, 1967], No. 30649/68. Heading H1K. [Also in Division G4] An information transfer system has a plurality of stages each comprising a binary information storage unit and an associated intermediate storage unit, information being transferred from the former unit to the latter in response to a first condition of a variable energizing source and from the latter unit to the information storage unit of another stage in response to a different condition of the source, each unit comprising a flip-flop having two transistors, emitters of which are directly connected and the bases and collectors of which are cross-soupled by direct connections. Circuits.-Fig. 1 shows two stages FFI, FF3 of a shift register and intermediate storage FF2. Positive and negative portions of a clock voltage copy PF1 into FF2 and FF2 into FF3, respectively, via diodes 7, 8 and 9, 10. A second embodiment replaces each diode 7, 8, 9, 10 by the emitter-collector path of a respective extra transistor, the collector and base of which are shorted together. A third embodiment replaces each diode 7, 8, 9, 10 by an extra emitter of the destination transistor. Thus, e.g., the collector of transistor 1 is connected directly to a second emitter of transistor 3 rather than through diode 7 to the collector of transistor 3. Construction.-Pigs. 4, 5 (section along A-A in Fig. 4) show part of a monolithic integrated semi-conductor circuit of the triple-diffused type for the second embodiment, 1, 2, 3, 4 being transistors as in Fig. 1, 18, 19 being the transistors replacing the diodes 7, 8 of Fig. 1, and 11, 12, 13, 14 being resistors as in Fig. 1. The letters b, c, e mean base, collector, emitter. An oxide film is grown thermally on a P-type silicon substrate and holed photolithographically to permit diffusion in of impurities for the isolation, resistor and transistor functions. Using photolithographic techniques, aluminium is then evaporated on to form connections (shaded in Fig. 4). The connection to +Vc tunnels under the connections 37 (to earth) and 17 (to the clock voltage) at 38, without ohmic contact. Figs. 6, 7 (section along B-B in Fig. 6) show part of a monolithic integrated semi-conductor circuit of the single epitaxial type, for the third embodiment, 22, 23, 24, 25 being two-emitter transistors corresponding to 1, 2, 3, 4 of Fig. I with emitters 28, 43, 44, 29, 30, 31 &c., bases 42 &c., and collectors 41 &c., and 11, 12, 13, 14 being resistors as in Fig. 1. An N-type epitaxial layer is deposited on a P-type silicon substrate and silicon oxide masking, diffusion techniques and photolithographic techniques are used to form the isolation, resistor and transistor functions. Metallic connections (shaded in Fig. 6) are provided over the silicon oxide insulator, crossing each other at different levels without ohmic contact.

Abstract: 1,226,793. Transistor timing circuits. ANTOMA (HAIRDRESSING) CO. Ltd. 11 March, 1969 [7 March, 1968], No. 11272/68. Heading H3T. [Also in Division H2] An oven is provided with a timing device comprising a variable impedance and a capacitor, the charge on the capacitor being operative to trigger a semi-conductor device so as to terminate the cooking operation of the oven. A switch S8 is closed by a coin such that with a switch S9 in the position shown a relay C is energized from lines L, N over a circuit including contacts A3. Energization of relay C closes self-holding contacts C1 and contacts C2 whereby switch 58 may be opened. One of switches S1-S7 is closed and a capacitor Y2 charges over a circuit including resistor R4, diode D1, resistor R3, voltage stabilizer R2, Y2, Z2, one of the impedance V1 to V7 according to which switch S1 to S7 has been closed and normally closed contacts A1. Cooking is started by pressing push-button P1 which, on the one hand, energizes relay B which controls the operation of the oven and, on the other hand, energizes a timing relay A over a circuit R5, D3, R6, V8, R7, normally closed contacts A2 and R12. Energization of relay A opens contacts A1, A2 and changes over contact A3. The changeover of contact A3 maintains the energization of relay A, opening of contact A, leaves capacitor Y2 charged up according to the meal chosen and opening of contact A2 allows a capacitor Y3 to begin charging A at a rate determined by the variable resistor V8. When the ratio of the voltages acquired by capacitors Y2, Y3 reaches a preset value a transistor T1 becomes conductive thereby producing a firing signal for a thyristor SCR. Conduction of the thyristor SCR short-circuits the relay A whereupon the relay is de-energized and contacts A1, A2, A3 return to their normal positions to deenergize the relay B to terminate the cooking operation.

Abstract: 1,232,496. Valves. PITNEY-BOWES Inc. 10 Dec., 1968 [14 Dec., 1967], No. 58723/68. Heading F2V. [Also in Division G4] A fluidic device comprises an input conduit 22 which may receive fluid under pressure, e.g. from tube 60. Conduit 22 is normally closed by resilient diaphragm 26. A cavity 42 is vented to atmosphere by ducts 46. A second input conduit 34 receives fluid from a second pressure source and has connected part-way along its length an output conduit 52. In the absence of fluid pressure at 22, e.g. due to the presence of an object passing the end of tube 60, the fluid entering conduit 34 is vented to atmosphere to give low pressure at 52. In the presence of fluid pressure at 22 diaphragm 26 closes the outlet of conduit 34, causing high positive pressure at 52. In a modification (Fig. 2, not shown), the output conduit is connected to a Venturi in the second input conduit (134), whereby positive pressure at the first input (122) develops positive pressure at the output (148) while zero input pressure develops negative output pressure due to fluid flow in the Venturi.

Abstract: 1,239,135. Priority interrupt controller. STARKSTROM-ANLAGENBAU KARL-MARXSTADT. VEB. 3 June, 1969, No. 28045/69. Heading G4A. A plurality of interrupting units 0À1 to 0.47 supply a signal to one input of a respective AND gate U1 to U47. The AND gates are successively enabled by a counter 3 supplying a signal 1 to 47 via a decoder 2. The outputs of the AND gates are supplied to a decoder 4 which supplies a signal to flip-flops 5.1 to 5.4 which hold the address of the unit and to flip-flops 6À1, 6À2 which hold the priority interrupt level of the interrupting unit, and which also supply a signal to the counter. The interrupting units have priority levels I which is the highest level to III which is the lowest. A level signal stored in flip-flops 6.1, 6.2 causes the modulus of the counter to be altered such that the AND gates coupled to inputs having higher priority are the only gates enabled, e.g. with 15 rank III units, 16 rank II and 16 rank I, if no unit is requesting interrupt the counter successively enables all AND gates. If an interrupt rank III is being processed the counter enables gates 1 to 32 of ranks II and I. If a rank II interrupt occurs the counter enables gates 1-16 and if a rank I interrupt occurs the counter enables none of the gates.
