Title: Improvements in or relating to stop motions for knitting machines
IPC: D04B35/10
Filed: 1931-11-07
Abstract: 385,069. Knitting-machines. MELLOR, BROMLEY, & CO., Ltd., BROMLEY, T. C., and SHORTLAND, A., Minotaur Works, St. Saviour's Road East, Leicester. Nov. 7, 1931, No. 30929. [Class 74 (ii).] Stoppage of a knitting-machine, on excessive tension being put on the yarn and in the event of breakage or undue slackness, is effected by the movement of an overhead yarn guide and a dropper respectively, the latter being mounted at or near each yarn feeder. The invention is described in connection with a circular machine provided with a plurality of yarn guides 1, Fig. 1, each of which is carried by a hub 6 pivotally mounted on a carrier 3. The peripheral edge of the hub on one side of the pivot is shaped to constitute controlling and operating portions 11, 12 respectively for engagement with a circular spring band 14 which is pressed against the hubs by radially adjustable pins 16, the shape of the controlling portion 11 permitting slight variation in yarn tension whilst maintaining the yarn guide substantially upright. Excessive tension however brings the operating portion 12 into engagement with the spring 14 and the yarn guide is moved to a horizontal position, whereupon the hub extension 6a engages and turns a toothed ring 25 about its pivot 27 to effect stoppage. Movement of the ring 25 rocks a shaft 33 through a pin connection 36 and arm 34 and operates mechanism 39 associated with the belt striking gear. The dropper arrangement comprises a finger lever 44b, Fig. 5, and a dropper 46a pivoted at 45 and 47 respectively, the finger lever being provided with a projection 48a for supporting the end 49 of the dropper and being adapted to rest on the yarn passing between guides 50, 51. On yarn breakage or in the event of undue slackness the movement of the finger lever 44b allows the dropper to rock on its pivot 47 and effect stoppage. Specification 281,042, [Class 74 (ii), Knitting &c.], is referred to.

Title: Process for concentrating rubber latex and similar vegetable juices
IPC: C08C1/075
Filed: 1935-11-08
Abstract: Before the initial or later stages of concentrating latex, the non-rubber substances rendering the latex sensitive to coagulation are removed by treatment with adsorptive agents or partial coagulation.  The concentration may be by any of the usual methods as centrifuging, evaporation, creaming, filtration. Stabilizers may be added before, during or after the concentration.  Adsorptive agents include active charcoal, silica gel, aluminium oxide, and ferric oxide.  Coagulants may be electrolytes and/or non-electrolytes such as alcohol, formic acid or colloidal ferric oxide.  In examples, latex was treated with a regulated amount of formic acid and, after stirring for 3 hours, made alkaline with ammonia; the coagulum was then filtered off and the latex then concentrated by evaporation or centrifuging; latex preserved with ammonia was filtered through a "zinc chloride charcoal" bed and concentrated by evaporation or creaming with potassium polyacrylate.

Title: Improvements in or relating to indexing circuit arrangements for colour television receivers
IPC: H04N9/24
Filed: 1962-08-15
Abstract: 986,017. Colour television receivers. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Aug. 15, 1962 [Aug. 18, 1961], No. 31312/62. Heading H4F. The invention relates to a circuit arrangement for providing a signal of suitable phase and frequency for application to the control electrode 3 of the single-beam, indexing, tube cathode-ray tube 1 whose screen 2 is provided with run-in indexing strips and with main indexing strips which in the particular embodiment shown occur after every two colour strips. The photomultiplier 4 is sensitive only to ultra-violet light and responds only when the beam scans the run-in strips and indexing strips which are made emissive of ultra-violet light. The former gives rise to a signal of frequency fh which is passed by the tuned amplifier 7 and is used to provide a phase reference signal for a frequency dividing circuit 9. The indexing strips give rise to a signal of frequency fi which is passed by the tuned amplifier 8 and divided by a factor # ( = 3) in the frequency dividing circuit 9. This signal of frequency fi/# is frequency added in the circuit 10 to a signal of frequency fr derived from the transmitted composite video signal and comprising a reference frequency signal locked on to the sub-carrier burst (fr = 4À5 Mc/s., fi=12 Mc/s., therefore #i/# +fr= 12/3+4.5=8À5    Mc/s.). In order to reduce errors caused by the second harmonic component of either of the signals fi/# or fr, the stage 10 comprises a pair of multi-grid valves connected in push-pull (Fig. 2, not shown) or an electron beam deflection tube (Fig. 3, not shown) or a four diode ring modulator. The stage 11 subtracts the   signal of frequency #i/# + #r from the signal #i to provide a signal of frequency (1 - 1/#) #i -#r. This signal is frequency added in stage 13 to a signal fr + chr corresponding to the suppressed carrier chrominance signal. If desired, the chrominance signal may first be converted to dot-sequential form. Second harmonics may be eliminated in the circuit 13 by using circuit arrangements similar to those used in the stage 10. The output signal from the stage 13 is added in the stage 26 to either the monochrome signal M or the unconverted luminance signal Y. In addition to eliminating frequency errors primarily due to second harmonic components, the Specification also discloses how phase errors may be reduced by ensuring that the time constants inherent in the particular stages of the circuitory have preselected values. The final signal applied to the control electrode 3 of the tube 1 has a frequency #s which is equal to (1-1/#) #i which in itself is equal to #i/α where α is the ratio of the number of indexing strips to the number of groups of colour strips, i.e. 2/3 is the particular embodiment described.
