Filed: 1969-06-26
Abstract: 1,247,207. Foamed polymers of aromatic polycyanates. FARBENFABRIKEN BAYER A.G. 26 June, 1969 [12 July, 1968], No. 32238/69. Headings C3C and C3R. Foamed polymers are made mixing an aromatic polycyanate or prepolymer thereof up to 10% by wt. of a blowing agent which decomposes above 50‹ C. to liberate gas and heating the mixture at 100-300‹ C. so as to polymerize the polycyanate to a resin which at the same time foams up. The polycyanate used in the examples is 2,2<SP>1</SP>-bis-(4-cyanatophenyl)- propane, but may also be derived from a novolak and cyanogen chloride. The blowing agent may be azoisobutyric acid dinitrile or diethyl ester, azodicarbonamide or diphenylsulphone- 3,3<SP>1</SP>-disulphone hydrazide.

Filed: 1952-12-22
Abstract: 715,307. Piling fibrous slivers &c. CELANESE CORPORATION OF AMERICA. Dec. 22, 1952 [Dec. 21, 1951], No. 32495/52. Class 120(3) [Also in Group XVII]. Apparatus for piling continuous filaments or fibres of textile material arranged in a single strand or rope, i.e. in the form of a tow, comprises traverse means for directing a tow into a carton, supporting means adapted to carry a pair of cartons, and means for shifting the supporting means to present the cartons carried thereby alternately to the traverse means. A carton 82 is placed in each of the carton holders 35, 36 which are supported on a carriage 32 movable on tracks 31. In Fig. 1, carriage 32 is positioned so that holder 35 is beneath a traverse mechanism 27 which includes feed rolls 97, 98 of which 97 is driven by a motor 101, Fig. 3. The tow 28 is folded or pleated, Fig. 9, by the combined action of two piston rods 121, 118 working at right angles to each other and producing a lateral and longitudinal movement of a plate 104 of a feed assembly 103. A sufficient length of tow is fed to fill the carton and also a major portion of a filler sleeve 67 which rests just inside the holder 35, after which the carriage 32 moves under the action of a piston rod 75 so that the filler sleeve 67 and carton holder 35 are beneath a platen 24. The tow is then severed by a cutter assembly and the traverse 27 continues to feed the tow which is now received by the carton in holder 36. After. placing a cap 123 over the mass of folded tow in the filler sleeve 67, a' hydraulic cylinder 22 is operated and platen 24 compresses the package. Jacks 77 are then operated and a pivoted platform 59 is slightly raised, thus causing rods 64 to lift the filler sleeve out of the carton holder 35. Straps 125 may then be inserted through grooves 26 in the lower face of the platen 24 and after being guided completely round the carton and cap the straps are joined by clips to hold the package compressed. Carton holder walls 42, 43 and 53, Fig. 7, which are hinged are then unlatched, the platen 24 is raised, thereby allowing jacks 77 to tip the platform 59, and the package slides out of the holder 35 ready to receive a cover 128. After release of the jacks 77, the filler sleeve 67 is held clear of the holder 35 by means of a latch mechanism, an empty carton is placed in the holder 35, which is closed and latched. The filler sleeve 67 is then allowed to drop into the carton 82' which is ready to receive the next load of tow. When the carton in holder 36 and' filler sleeve 68 are charged the carriage 32 is moved back to the position shown in Fig. 1 and the cycle of operations is repeated..

Title: Electronic circuit arrangement with at least one integrated circuit

Filed: 1969-06-30
Abstract: 1285621 Integrated circuits FORDERUNG DER FORSCHUNG AN DER EIDGENOSSISCHEN TECHNISCHEN HOCHSCHULE GES ZUR 30 June 1969 [6 July 1968] 32941/69 Heading H3T [Also in Division G4] Collector and base supply impedances of transistors of one conductivity type in an integrated linear or switching circuit are constituted by constant current devices having their currents determined by transistors of the other conductivity type and using a common reference voltage supply which varies with temperature in the direction necessary to maintain the currents constant. The resistors may thus be eliminated from the integrated circuit, the one resistor which may be needed for the reference voltage supply being external to the circuit. Preferably the current determining transistors are of the lateral type. Fig. 7 shows a bi-stable circuit in which T2 1  and T2 2  are constant current transistors using a common reference voltage source T1 which may alternatively be a plurality of diodes, mounted in thermal proximity to the circuit. Triggering is effected through reverse biased diodes D5 3 , D5 4  acting as capacitors. Steering of the triggering pulses is effected by diodes D5 1 , D5 2  which are appropriately biased by the condition of the circuit. Fig. 7 shows an integrated logic circuit using constant current biasing transistors T2 1 , T2 2  and a common reference source. A plurality of the bi-stable circuits may provide a counter (Figs. 9-11, not shown) in which case the constant currents may be reduced for the later stages since switching can be slower. The constant current transistors may supply their current through amplifiers of the same or opposite conductivity type (Figs. 9 and 10, not shown). The reference voltage source may then comprise two transistors. A single reference source may serve a plurality of constant current transistors which may in turn provide current to groups of constant current transistors associated with circuits (Fig. 11, not shown).

Title: Improvements in and relating to buffer amplifiers
Inventor: RAINGER PETER
IPC: H03F3/30
Filed: 1963-08-20
Abstract: 1,059,112. Buffer amplifiers. BRITISH BROADCASTING CORPORATION. July 20, 1964 [Aug. 20, 1963], No. 32953/63. Heading H3T. In a transistor buffer amplifier having a parallel input stage and a push-pull output stage, and intended to have unity gain, the drop in voltage across the input transistors is compensated at least in part by the voltage drop in the second stage which is of opposite sign to that of the first. In the simplest arrangement, two emitter-follower stages are used, one having a PNP transistor and the other an NPN. If both transistors are of the same type they are connected in different configurations, e.g. common collector and common emitter, with negative feedback to equalize the gains of the two stages. In Fig. 2, the two parallel amplifiers comprise amplifiers, transistors 10 and 15, and transistors 18 and 19 respectively. If the load is capacitive, a sudden change in input voltage might tend to cut off one of the input transistors as the following transistor could not follow the voltage change immediately. The diode 21 then conducts and passes the signal through the second transistor of the other parallel pair. Resistor 22 reduces the standing current of the transistors. The gain can be increased by replacing or supplementing the emitter resistors by the emitter-to-collector paths of further transistors.

Abstract: 300,582. Jillings, C. S., (Assignee of Berg, W. E.). Nov. 15, 1927, [Convention date]. Stream-cutting machines; rolling machines.- Ornamental blocks or other clay products are formed by extruding plastic clay through a die and subjecting the extruded column to the action of a rotatable embossing roll prior to cutting. To prevent adherence of the roll to the column, it is vibrated by a pneumatic hammer; also the surface of the column is dried by air jets in advance of the roll. As shown, applied to a brick cutting machine, wherein an extruded column of clay is severed by oscillating, spaced cutting- wires, the column 4, supported by a belt 9, is passed under an embossing-roll 15. The roll 15 is mounted in arms 11 slidably supported in guides 10 in a block 7 and adjustable through a handwheel 25, screw 19 and yoke 17. The screw 19 works through a nut 22 which is held against rotation but has limited movement against a spring 24. A pneumatic hammer 26 acts on the roll 15 through the screw. Similar rolls 35 may be provided at the sides of the column. Adjustable air jets 36, supplied through a pipe 37, are interposed between the die and the rolls. The rolls are obtained by casting the embossing surface in a matrix obtained from a master pattern produced by making a mould of the original pattern in a plastic, non-adhesive substance.
