Title: Improvements in or relating to lap-forming apparatus
IPC: D01G27/04
Filed: 1951-03-30
Abstract: 711,599. Lap-forming apparatus. AKT.- GES. J. J. RIETER & CIE. March 30,1951 [June 5, 1950], No. 7480/51. Class 120(1) During the formation of a sliver-lap by rolling slivers on a sleeve, the roll is pulled on to two rolling surfaces, the rotation axis of which are parallel to the axes of the sleeve, and the pulling force is steadily increased proportionately to the increasing diameter of the roll by using the displacement of the sleeve due to such increasing diameter to reduce the volume of a predetermined amount of gas in a closed conduit system. In the machine shown, lap A is delivered from calender rollers 3 and wound on a sleeve frictionally driven by lap rollers 4 carried by a rod 8 rotating in bearings on pressure heads 6 on the ends of pull rods 7. By depressing a pedal 14, a piston 12 in a cylinder 13 is moved to open pipes 15, 20, to the relieved piston portion so that air flows from a tank 19 into cylinders as at 11 and exerts on top of pistons 10 a pressure controlling the pull on the rods 7. Thus, as the rods and the pistons 10 are lifted by the increased lap diameter, the air above pistons 10 is displaced into the tank 19 and checked by a valve 21. On completion of the lap, pedal 14 is lifted to lower the piston 12 so that air above each piston 10 escapes through the pipe 15 and a vent 13<SP>1</SP>: air again flows from the tank 19 into the cylinder 13 and through pipes 16, 17, into the cylinders 11 below the pistons 10 causing rapid upward movement thereof to raise the lap for removal. When a fresh sleeve has been mounted, pedal 14 is depressed and piston 13 resumes operative position: air again flows into the upper parts of the cylinders 11, the pistons 10 of which rapidly descend, displacing the air on their underside through pipes 16, 17, and vents 24 which have a throttling screw 25 to control the sinking rate of the freshly inserted sleeve: as soon as each piston 10 obturates mouth of pipe 16 the flow of air from each cylinder 11 is cut off therefrom and air remaining under piston 10 must escape through pipe 17, such escape being retarded by a throttle valve 18 so that the sleeve is lowered gently into position.

Title: Condition detecting circuit
IPC: G05D3/14
Filed: 1974-02-20
Abstract: 1455352 Impedance measuring bridges HONEYWELL Inc 20 Feb 1974 [20 Feb 1973] 7679/74 Heading G1U [Also in Division G3] At least one supply point of a bridge circuit including a condition-responsive resistor is the wiper of a potentiometer, and should the wiper connection fail a diode D4, which under normal conditions does not conduct, applies a reference voltage to the bridge which thus produces a predetermined output. As shown, the supply point is the wiper of potentiometer R2 in a bridge which is part of the control circuitry for a bi-directional motor M1 which operates a fuel valve 16 in a heating system, the temperature of which is sensed by an N.T.C. resistor R6 in the bridge. Outputs from the bridge are fed to operational amplifiers A1, A2, which, when the sensed temperature falls outside a permitted range, operate motor control unit 17. As motor M1 actuates valve 16 it also moves the potentiometer wiper to re-balance the bridge and move the permitted range to include the actual temperature.  A second embodiment, Fig. 2 (not shown) comprises a further potentiometer (R 15) and an additional "safety" diode (D5). The wiper of this potentiometer, which may be manually controlled, constitutes the other bridge supply point. Should both wiper connections fail simultaneously, the input circuitry of the amplifiers is arranged so that diode D4 conducts.

Title: Improvements in the manufacture of polymerized products from styrol and its homologues
IPC: C08F12/08
Filed: 1925-03-21
Abstract: Styrolene and its homologues are polymerized by heating to different temperatures and for different lengths of time to form three series of compounds referred to as a -, b -, and g -metastyrolenes.  The a -compounds are prepared by heating styrolenes of 92 per cent purity and above at temperatures and for times varying from 140 DEG  C. for 20 hours to 175 DEG  C. for 5 hours, according to a curve which is supplied, preferably in narrow sealed tubes held vertically.  The products are tough, transparent and colourless and can be cut with a knife.  Bubbles are prevented by polymerizing in a vessel in which a large meniscus is formed, for example in a sealed tube placed horizontally.  In this case a rod with a flattened side is obtained. To prevent subsequent cracking of the surface, the products may be heated to about 100 DEG  C. for 3-24 hours.  The products prepared from 2 : 4-dimethyl- and 4-methylstyrolenes are elastic substances which may be hardened by heating.  The b -compounds are prepared by heating at higher temperatures or for longer periods than are used in forming the a -compounds.  The compounds are transparent but lose their transparency on standing, and are fractured with a knife or a hammer.  The g -compounds are prepared by heating styrolene or its homologues in presence of an accelerator of polymerization, preferably an organic peroxide such as benzoyl peroxide or triphenyl methyl peroxide.  Barium peroxide also acts as an accelerator.  The compounds are transparent, yellowish, brittle substances.  Dyes or pigments may be added. Specifications 232,909 and 233,649 are referred to.  The Specification as open to inspection under Sec. 91 (3) (a) refers also to the use of organic peroxides, calcium chloride, nitro compounds and quinones as reagents which accelerate or retard polymerization.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to the treatment of waste acid pickle liquor
Inventor: SIMPSON PETER
IPC: C01C1/242
Filed: 1960-03-05
Abstract: Ferrous hydroxide and ammonium salts are obtained by adding ammonia liquor simultaneously with waste acid pickle liquor to a heated vessel operating under vigorous agitation at a temperature above 50 DEG C. but not exceeding 150 DEG C. under pressure conditions sufficient to prevent boiling.  The reacted liquor is removed from the vessel and the ferrous hydroxide separated, e.g. by centrifuging. The remaining iron in part of the reacted liquor is precipitated as ferric hydroxide by aeration and the supernatant liquor is evaporated to obtain ammonium salts.  The other part of the liquor from which ferrous hydroxide has been removed is recycled to the waste acid pickle liquor.  The ammonia and waste acid pickle liquor may be added in stoichiometric proportions and the acid may be sulphuric, phosphoric, hydrochloric, or nitric acid.  The ammonia liquor may be ammonia effluent liquor from a coke oven scrubbing process or it may be an aqueous solution of synthetic ammonia.

The compressor is self draining under the action of gravity. Air is drawn into the low pressure cylinder through ports 9 and is discharged through ports 7 (see Fig. 3, not shown) into the chamber 19 and then into the high pressure cylinder through ports 20 and is discharged through ports 26 together with a quantity of oil which is separated from the air and returned to a reservoir (not shown) which supplies the gear pump 21. The reservoir may be so placed that it floods the gear pump 21 when the compressor stops.

[Also in Group VI] In conveying material through a bread &c. baking oven or tunnel 25, Fig. 6, the bread tins are conveyed by a succession of stationary rollers 2 all rotated in the same direction and from the same ends, such rollers minimizing vibration of the dough or other material. The conveyer rollers extend through a number of zones of different temperatures, Fig. 8, such as a prover, an oven, and a cooler. The speed of the conveyer rollers may be varied to vary the time of passing the material through the varying temperature zones. The varying zones are heated by independent furnaces 37 heating, e.g., steam tubes 26 in each zone.
