Title: Improvements in or relating to the continuous sorting and testing of yarns and threads
IPC: G01N33/36
Filed: 1932-09-23
Abstract: 394,184. Cleaning and testing yarns. BORZYKOWSKI, B., Villa Hela, Herzbergon-Harz, Germany. Sept. 23, 1932, No. 26478. Convention date, Sept. 23, 1931. [Classes 120 (ii) and 120 (iii).] Threads, during a single unwinding operation, are simultaneously cleaned, tensioned, tested for strength and tested for uniformity. The threads are unwound from a bobbin, spinning cake or hank and passed between two cheeks faced with closely shorn skin or pelt, preferably shorn to a length of 3 mms., and pressed together with a regulatable force. This cleans and tensions the threads and tests for weak places. The thread then passes through an apparatus for testing uniformity of thickness, comprising a pair of pivoted arms between which the thread passes, and whose movement, upon passage of an excessively thick or thin portion, actuates a lever mechanism to sever the thread. The thread may be passed through a cleaning eyelet after the first cleaning device, and may be finally treated with a preparation, e.g. an oiling preparation, by passing over a roller which dips therein, the length of arc of contact being adjustable.

Abstract: 1429935 Capacitors JOHNSON & PHILLIPS (CAPACHTORS) Ltd 6 June 1973 [7 June 1972] 26486/72 Heading H1M A wound capacitor comprisings ynthetic resin dielectric material films and electrode strips is impregnated by introducing insulating liquid to the winding and allowing the winding to soak in the liquid at ambient temperature, part at least of the soak being conducted under a pressure below atmospheric. Each dielectric layer may comprise three polypropylene films, one being thicker than the other two and different winding tensions may be employed for the films so as to obtain lateral corrugations which aid penetration of the impregnant, e.g. mineral oil. Soaking may take place for one hour before the vacuum employed during impregnation is released, then at atmospheric pressure for 23 hours.

Title: Methods and apparatus for severing a continuous rod of material in the tobacco industry
IPC: A24C5/28
Filed: 1963-07-08
Abstract: 1,027,439. Cigarette making machines; K. KÍRBER. July 8, 1963 [July 14, 1962], No. 26914/63. Heading A2C. Apparatus for severing lengths from a continuous tobacco or like rod comprises a rotary cutter carrier 3 provided with a plurality of cutter holders 4 adapted to support cutters 57 having eccentric cutting edges, each holder being rotatable about its respective axis and in which the cutting edges in use are operative successively to cut the rod. The apparatus is provided with a main shaft 10 which drives a first transmission 9 having an output shaft 8 connected to a second transmission 7. The output shaft 6 of the second transmission 7 drives the carrier 3 which includes planet gears on the shafts of the cutter nolders 4 which mesh with a stationary sun gear within the carrier 3. The shaft 10 also drives a transmission 11 whose output shaft 11a is connected through reduction gears 12 to a reciprocating mechanism 13. The mechanism serves to reciprocate axially a non-rotatable tubular extension 27 of the sun gear. Shaft 6, which revolves within the extension 27, is also reciprocated axially. The movement of the carrier 3 from the full line to the dashed line position shown takes place at the same speed as that at which the rod S to be cut is travelling and is timed to occur at the instance when a blade 57 cuts the rod through a ledger tube 5. An adjustable sharpening disc 70 may be provided. In the embodiment described three holders 4 are provided, the shafts of which make 4¢ revolutions to 1 revolution of the support 3. By selecting single or double cutters 57 for the holders 4, the apparatus may be made to cut, on each revolution of the carrier 3, a single sextuple length of rod, two triple lengths, three double lengths, or six single lengths. Double lengths alternating with two single lengths may also be achieved.

Title: Improvements in heating installations, notably such as the installations of heating by heavy fuels
IPC: F23N5/02
Filed: 1930-09-10
Abstract: 369,186. Liquid-fuel burners. LANSER, A., Corseaux, Vevey, Switzerland. Sept. 9, 1930, No. 26941. Convention date, Sept. 10, 1929. Void [Published under Sect. 91 of the Acts]. [Class 75 (i).] Electrically controlling fuel and air supplies.- A mercury switch j in the circuit to an electric motor e driving the fuel pump c. and the " carburant" compresser d of a liquid fuel burner heating the boiler a of a heating installation is moved by the plunger m of a solenoid n to the closed position, as shown in the Figure, when the solenoid circuit is completed on the closing of a thermal switch h by the ambient temperature. A mercury switch k, coupled to the switch j, and short-circuiting an electromagnet r, is simultaneously moved to the open position, but the breaking of the short-circuit is delayed by a perforated inclined partition in the switch. Should ignition of the burner not be effected before the mercury has passed through the partition or ignition fail while the burner is in operation, the electromagnet r operates an armature q<1> to release a gracityoperated switch p to break the motor circuit. If ignition is effected normally, the heat of the burner causes the expansion of gas in one of the bulbs of a U-tube o and thereby causes the displacement of mercury in the U-tube to complete a second short-circuit across the electromagnet r before the first short-circuit is broken. A thermal switch i which opens if the boiler becomes excessively heated is arranged in series with the switch hand solenoid n. The switch p is re-set manually.

Totalizing-counters; approximation by eliminating unnecessary figures.-In a calculating machine the totalizing-counter is provided with a correcting device to show the approximate result by the elimination of the unwanted decimal figures, the numeral wheels tc the right of the predetermined point being zeroized and unity, if necessary, added to the first significant denomination. According to the Specification a shaft 161 carries a number of gears 162 engaging pinions on the numeral wheels 112 the gears 162 associated with the denominations to the left of a selected point being connected with other gears 163 each. in mesh with the numeral wheel pinion next higher to that of its gear 162. Each gear 163 has attached thereto a segment 164 with five teeth one or other of which comes into the path of movement of a single-toothed disc 166 when the corresponding numeral wheel indicates " 5 '' to " 9." The disc 166 is secured to a sleeve 169 slidably adjustable on a shaft 161 by means of a handle 168 the shaft having a key 167 with notches 180 engaged by a spring 179, Fig. 3, on the sleeve to hold it in set position. The sleeve carries a set of freely rotatable pinions 171 in mesh with the gears 162. A rotary and axial movement is imparted to the shaft 165 and sleeve 169 by means of a fly-nut 178 through pinions 176, 177. By the axial displacement pins 171 on the sleeve are moved into alignment with pins 174 on the pinions 175 and on the rotary movement the pinions 175 serve to restore the corresponding numeral wheels to the zero position. At the same time if the highest cancelled wheel stood at " 5 or over " the corresponding segment 164 will be engaged by the toothed disc 166 and will be turned thereby to rotate the higher numeral wheel an additional step.

Title: Steam reforming hydrocarbons
Inventor: BRIDGER GEORGE WALTER
IPC: C01B3/38
Filed: 1964-07-02
Abstract: A process for reforming carbon-forming hydrocarbon feedstock (which is defined in the Specification and examples of which are liquefied petroleum gas (propane/butane) and light distillates) with steam and/or CO2, optionally with oxygen, comprises passing the steam/CO2/feed mixture (preheated) over a two-stage catalyst.  The second stage catalyst is conventional, i.e. under conventional steam-reforming conditions carbon would be formed from a straight-run petroleum distillate boiling in the range 30 DEG  to 220 DEG  C., examples being Ni or cobalt on alumina and/or silica.  The first-stage catalyst is "modified," i.e. steam-reforming of the above distillate at 800 DEG  C., 200 p.s.i.g. and a steam ratio of 3, would not be accompanied by carbon formation.  Examples are: alkali-promoted Ni, e.g. as described in Specification 953,877; nickel-platinum; alkali metal chromate- and dichromate-promoted Ni (Specification 1,002,978); Ni chromite, cobalt chromite; Ni on coprecipitated chromia/alumina; alkali-promoted cobalt; and Ni and cobalt on an alkali-treated carrier.  The method is applicable to synthesis gas production (650 DEG  to 900 DEG  C., steam ratios 2.5 and above) and to town gas production (550 DEG  to 700 DEG  C., steam ratios 1.5 to 3).  Three specific examples are described.
