Filed: 1962-08-23
Abstract: 955,777. Carding-engines. MASCHINENFABRIK RIETER A. G. Aug. 23, 1962 [Sept. 1, 1961], No. 32459/62, Heading D1N. Apparatus for removing a carded web from a cylinder includes sawtooth discs co-axially mounted parallel to the axis of the cylinder and smooth-surfaced discs that extend between the sawtooth discs. The sawteeth take the web from the cylinder and the smooth discs remove the web from the teeth. The sawtooth discs 6 preferably rotate in the same direction as the cylinder 3 (in this instance a doffer) and their peripheral speed is about the same as that of the doffer. Smooth surface discs 9 rotate at a peripheral speed 3 to 5% greater than that of the discs 6 and the peripheries of the discs 6, 9 intersect in such manner that, at the point of transfer between them, the web turns through an angle of about 90 degrees. A long arc of contact of the web with the discs 9 is obtained by passing the web between the discs 9 and a roller of smaller diameter than the discs, there being a predetermined clearance between discs and roller.
Patent GB-969348-A (GB)
Title: Improvements in and relating to heat source detection systems
IPC: B61K9/06
Filed: 1961-09-11
Abstract: 969,348. Detecting overheated wheel journals. GENERAL SIGNAL CORPORATION. Sept. 11, 1961 [Sept 19, 1960]. No. 32499/61. Heading B7N. In a system for detecting overheated journals on rail vehicles, means are provided for determining whether the overheated condition is due to the journal or to dragging brakes. The arrangement includes infra-red radiation detectors RD1, RD2 positioned on opposite sides of the track and arranged to scan each passing wheel along a line parallel to the track and passing through the hub, a magnetic wheel detector WD1 positioned on a line passing through the radiation detectors and similar wheel detectors WD2, WD3 positioned approximately 10 inches to either side of detector WD1. Output pulses are produced by circuit 15 when a wheel passes over detector WD1 and by circuit 25 when a wheel passes over either detector WD2 or WD3. The pulse from circuit 15 triggers a monostable flip-flop 16, which produces an output pulse of short duration, and also triggers a bi-stable flip-flop 17 which is returned to its initial condition by the pulse from circuit 25. The output from flip-flop 16 triggers a second mono-stable flip-flop 19 which produces an output pulse for a predetermined time after flip-flop 16 has returned to its initial condition. The output from the detectors, e.g. RD1, is applied via a preamplifier 21 and amplifier 22 to a hub signal storage circuit 20 and to a hub and web signal comparing circuit 23. In the signal storage circuit 20 the amplified signal is passed to ground except during the period when a gating pulse from flip-flop 16 is present and during this period the signal is stored if its amplitude exceeds a predetermined value. With the arrival of a gating pulse from flip-flop 19 the signal is applied to an analogue recording pen AP No.1 and also to the hub and web signal comparing circuit 23. If the signal does not exceed the predetermined value the arrival of the gating pulse from circuit 19 generates a small signal which is recorded by the analogue pen to indicate the passage of a train wheel. In the comparison circuit 23, in the presence of a gating signal from flip-flop 17 the hub signal is stored and compared with the output of amplifier 22 which is now indicative of the web temperature. If the hub temperature signal exceeds the web temperature signal an output is supplied to marker pen MP No. 1. The analogue and marker pens record on the same graph and each analogue marking indicates, depending on its amplitude, a passing wheel with a normal or overheated journal. An overheated journal signal in the absence of a corresponding marker signal indicates a dragging brake. The output from flip-flop 17 also acts in a circuit 18 to operate a relay R during the period a train is passing through the test location. The relay opens a shutter which protects the infra-red detector in each unit in the absence of a train and additionally switches on the recorder. Reference has been directed by the Comptroller to Specification 906,170.

[Class 100 (iv)] Type-wheel machines; types.-A machine for printing varying numbers in words comprises a disc or sector for each column of the amount on which is fixed transversely a series of typefaces in which each numeral digit, except ten and eleven in the pence, is represented by its name irrespective of its denomination ; the machine prints amounts in the form one-threefive pounds, one-six shillings &c. In the machine shown in the Figure, printing is effected by a platen 32 against steel type-faces 23, which are arranged transversely on sectors 22 mounted on a common axle 24 and having a spring driving-connection with the axle. The sectors are set by means of keys 12 arranged in vertical rows, corresponding to the sectors, on a keyboard 11. The depression of each key pushes forward and latches a spring-loaded pin 14 which is slidably mounted in a collector member 13. After all the keys desired have been depressed, the collector 13 is swung forward on arms 17, 18 by a link 19 cam 20, and cam roller 21. The collector pins then depress stops 31 in an arcuate frame 30. At every actuation of the machine the axle 24 and sectors 22 are rotated by linkage 27, 28 and a cam 26 until each sector is arrested by the engagement of a tail 35 on an arm 25 with a projected stop 31. The platen then takes an impression. At the end of the operation, the sectors return, pressing back the stops 31 by rollers 33 mounted in slots 34 in the arms, the pins 14 are unlatched and the collector returned to its position near the keyboard in readiness for the setting up of the next amount. The amount may be set up on the key-board while the previous amount is being printed. The unlatching- mechanism may be disabled if an amount is to be repeated. The words " pounds " " shillings " &c. are carried on the type-faces of the preceding units. Printing may be effected through an ink ribbon or carbon paper, or by an inking-:roller, or the type-faces may be intaglio or print negative impressions) or may be slotted to co-operate with a resilient platen. Interlocks may be provided on the keyboard so that no two keys can be depressed in the same column, the depression of the second releasing the first. The stops 31 may be spring-loaded and held by catches which are automatically released after impression. The machine may be controlled by record-cards or similar means. Specification 193,176, [Class 100 (iv)], is referred to.

Abstract: An acidifying medium for use in manufacturing baked articles is prepared by fermenting a mixture containing nutritive substances, such as flour from cereals or other sources, with leaven or leaven bacteria under conditions which favour the development of the bacteria.  The acidifying medium thus produced is mixed with dough which contains yeast and which may be partially fermented, and the acidified dough loosened under conditions which favour the development of the yeast and then baked.  Alternatively the acid liquid may be used as the liquid for mixing with flour and yeast to form the dough.  The acidifying medium may be obtained in powder form for addition to the dough by mixing the acid liquid obtained by fermentation with flour, preferably flour rich in starch which is capable of absorbing a large amount of water, and then drying and grinding the mixture. The acid liquid produced during the acid fermentation may be partially neutralized by calcium carbonate &c. To avoid undesirable subsidiary fermentations the fermentation with the leaven or leaven bacteria may be carried on for several hours at two different temperatures, first at about 32-35 DEG  C. at which temperature the undesirable bacteria are subdued and then at about 24-28 DEG  C.ALSO:A method of manufacturing baked articles from acidified dough using yeast as a raising medium comprises producing an acidifying medium by fermenting a mixture containing nutritive substances, such as wort, milk, flour from cereals or other sources, with leaven or leaven bacteria under conditions which favour the development of the bacteria, mixing the acidifying medium thus produced with dough which contains yeast and which may be partially fermented, loosening the acidified dough under conditions which favour the development of the yeast and then baking.
