Title: Acceleration detector
IPC: B60T8/171
Filed: 1974-05-29
Abstract: 1458845 Acceleration detector TELDIX GmbH 29 May 1974 [30 May 1973] 23765/74 Heading G1N (A) [Also in Division F2] An acceleration detector comprises means for forming, from a speed signal, an acceleration signal and means which vary the latter in response to a reduction of acceleration, such that the percentage reduction is greater than that of the acceleration. A sensor supplies pulses to a frequency to voltage converter which thus forms a direct voltage U e  proportional to vehicle wheel speed, from which capacitor 17 with resistors 11-14 and amplifier 10 form the acceleration signal U a , which is fed through resistor 39 to a comparison device comprising transistors 35, 36. Voltage divider resistors 32, 33 can be adjusted to alter the comparison voltage U r , which determines the acceleration threshold. A delay device comprises transistors 42 and 36 and capacitance 41, charged through resistor 40 in dependence on U a  and connected through diode 43 and transistor 45 providing output signal Ug. If U a <U r , transistor 36 conducts so that Ug appears at the output, but if U a >U r  it is blocked so that transistor 42 blocks and capacitance 41 charges until transistor 45 blocks removing Ug. With  increasing acceleration capacitor 21 is charged by U a  through diode 20, but on subsequent decrease of acceleration diode 20 blocks and with transistor 26 blocked, capacitor 21 discharges with a time constant corresponding to its capacitance and the resistance of 18, thus the feedback voltage through resistor 18 is higher than that due to the actual acceleration so that U a  decreases more rapidly than if it corresponded to the rate of change of U e , so Ug is restored more quickly to restore brake pressure. Switch 30 is closed by the brake pressure in a vehicle with anti-lock control, but for a low coefficient of friction it opens and transistor 26 conducts discharging capacitor 21 sooner so that Ug is not restored so soon. Instead of having resistor 25 and transistor 26, a transistor may be put in series with capacitor 21. Diode 20 may be replaced by a common collector transistor with, connected to the emitter, capacitor 21, charged by increasing U a , but with decreasing U a , on blocking of the transistor, providing decaying feedback. There may be a variable resistance in parallel with capacitor 21.

Title: Process for the production of composite metals suitable for hot rolling, by casting-on coatings of copper-zinc alloys
IPC: B22D19/00
Filed: 1929-07-30
Abstract: 329,572. Metallges. Akt.-Ges., Forster, H. von, and Lay, E. July 30, 1929. Cased forms; wire.-Composite metal articles such as compound ingots for the manufacture of bi-metallic wire by hot rolling are made by casting on an iron core a coating of a copper-zinc alloy containing over 60 per cent of copper, preferably 68 to 72 per cent, and less than 0.01 per cent of lead. Zinc containing less than 0.01 per cent of lead is used instead of the commercial brand in making the alloy. The alloy may also contain from 0.05 to 1 per cent of manganese, and may also contain iron in a proportion greater than that normally dissolved in the casting process. The iron may be dissolved from the core by maintaining, during casting, for a certain time a temperature which is favourable for this purpose. An alloy containing 70 per cent of copper, 29.7 per cent of zinc and 0.3 per cent of manganese melting at 920‹ to 950‹ C., when cast at a temperature of about 1000‹ C. around an iron core heated to from 1200‹ to 1250‹ C. and allowed to cool normally takes up about 0.05 to 1 per cent of iron.

Abstract: 240,489. British Thomson-Houston Co., Ltd., (Assignees of Devers, P. K.). Sept. 27, 1924, [Convention date]. Fused silica.-A method of making transparent bubble-free silica consists in fusing crystalline silica in a vacuum and then compressing the plastic mass by means of a gas at high pressure in order to eliminate cavities. An electric furnace for fusing the silica comprises a tank having a steel wall 21 several inches thick, and a cover secured by heavy bolts. A resistance heater 25 of graphite, which may have slots cut in it to increase its resistance, is connected to terminals 27, 28 that are cooled by fluid circulated through tubes 29. The space within the heater is closed by cup screens 36, 37 charged with graphite, and the lower screen supports the crucible.. The gas used for compression is preferably nitrogen and the pressure may exceed 3,000 pounds to the square inch. In operation, the crucible is charged with crystalline quartz and the furnace is evacuated. When the quartz reaches a temperature of about 1750 C., gas is pumped into the tank 21 until the required pressure is attained. The pressure of the gas reduces the bubbles or cavities in the fused mass and thus produces a slug of clear, glassy silica. The Specification, as open to inspection under Sect. 91 (3) (a), comprises also an apparatus for compressing the fused mass mechanically, as described in Specification 188,451 and for forming it into rods, as described in Specification 191,463. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the treatment of cellulose fabrics
IPC: D06M13/188
Filed: 1937-09-08
Abstract: 501,666. Esterifying and finishing cellulose fabrics. DISTILLERS CO., Ltd., and STAUDINGER, H. P. Sept. 8, 1937, No. 24496. [Class 2 (ii)] Woven or knitted cellulosic fabrics having a coherent uninterrupted structureless surface are prepared by superficially esterifying the fabric, rendering the surface layer of cellulose ester pliable, and then heat-treating the fabric under pressure sufficient to unify the surfaces of adjacent threads and form a structureless surface on top of the interior fabric structure. The degree of superficial esterification effected is preferably not less than 5 per cent nor more than 50 per cent of that possible. The surface layer of cellulose ester may be rendered pliable by treating it with a solvent and a plasticizer, e.g. o-phenyl phenol, p-isohexyl phenol, o- or p-normal octyl phenol, p-benzyl phenol or esters of crotonic acid. The fabric may be subjected to a preliminary mercerization. In an example, cotton muslin is steeped in acetic acid containing perchloric acid and esterified in a bath containing acetic anhydride, ethyl acetate and ligroin. The fabric is then steeped in a mixture containing o-phenyl phenol, benzyl alcohol, methylene chloride and alcohol, passed through a heated chamber to recover methylene chloride and alcohol, and passed between heated rollers. In a second example, linen cloth is mercerized, steeped in acetic acid containing perchloric acid and esterified in a solution containing acetic anhydride, crotonic acid and carbon tetrachloride. The cloth is steeped in a solution containing benzyl crotonate, ethylene glycol di-alpha-brombutyrate, acetone and alcohol, squeezed, dried, and pressed between hot plates. In another example, cotton, pretreated as in the first example, is esterified in a bath containing acetic anhydride, stearic acid, monochloracetic acid, magnesium perchlorate and benzene, soaked in a mixture of cyclohexanyl stearate, benzyl acetate, acetone and alcohol. passed through a heated chamber, and finally calendered between hot rollers. Specification 381,991 is referred to.

Title: Improvements in measuring devices for machines for winding or reeling yarns or threads
IPC: B65H63/08
Filed: 1930-08-15
Abstract: 352,299. Measuring stop-motion for winding and reeling machines. RUSHTON, J. L., Kay Street Works, Bolton. Aug. 15, 1930, No. 24535. [Class 120 (ii).] In a measuring device for winding or reeling machines comprising a measuring disc provided with a slot which is engaged by a feeler, the movement of the feeler disconnecting the drive, the disc is rotated by a resilient drive, which causes the disc to advance slightly upon withdrawal of the feeler, thus preventing re-entry of the feeler into the slot when the machine is restarted. By the use of interchangeable worm wheels, different lengths of yarn can be measured using the same disc. The shaft 10 which carries the yarn holder is driven through a clutch 11, 12, and drives a member 50 on a shaft 16 bv reduction gearing 17 .. 20, and worm gearing 22, 23. The measuring disc 24 is mounted loosely on the shaft 16, and is driven by the member 50 by means of a pin 52. A spring 51 is secured to the pin 52 and engages a hole 53 in the disc 24. When the shaft 16 begins to rotate, the pin 52 travels across a recess 54 in the disc 24, thus charging the spring 51 which is not strong enough to rotate the disc against the friction of the feeler-rod 38 of the stop mechanism. The pin 52 then engages the side of the recess 54 and so rotates - the disc until the feeler enters the slot therein. On withdrawal of the feeler the spring 51 rotates the disc sufficiently to prevent the feeler from reentering the slot when the machine is restarted. The rod 38 carries at one end an eye 42 engaging a bolt 43, so that longitudinal displacement thereof causes the crank 44 and shaft 46 to rotate slightly, whereby the arm 47 bears on the conical face of the disc 14 and so disengages the clutch 11, 12. The machine is restarted by depressing the lever 45, thus withdrawing the feeler from the slot and re-engaging the clutch. A stop 49 is provided to limit the movement of the shaft 46. To permit different lengths of yarn to be wound, the shaft 21 is provided with a unit having interchangeable worms 22, 55 of similar thread, the pitch of one being a multiple of that of the other.
