Abstract: 1,059,454. Moulding hollow articles by extrusion. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. June 28, 1965 [June 30, 1964], No. 27328/65. Heading B5A. [Also in Division B8] Filled and sealed bottles &c. are formed in succession from a continuously downwardly extruded plastics tube 2, which is vacuum shaped and sealed by sectional moulds 5 moving with the tube, the filling taking place in the moulds from a pipe 3 in the extrusion head. Co-operating sections 5 of a plurality of moulds are successively brought together round the tube 2, the lower edges 7 of each mould sealing the tube and a container being formed by the creation of a vacuum between the inner wall of the mould and the tube. The formed container is then filled, through a line 3 arranged in the extrusion head 1, closed by the edges 7 of the following mould and removed from the mould as it opens. The mould halves 5 are coupled together by links 11 and resilient guides may be provided to ensure proper closing of the mould halves. The vacuum is obtained by temporarily connecting channels 6 in the moulds to vacuum lines 16. To avoid the creation of sub-atmospheric pressure within the container, while it is being formed, air or another gas, if required in a sterile condition, may be supplied at atmospheric pressure, through a line 15. The filling liquid is supplied at such a rate that the liquid level remains approximately at the lower end of the filling pipe. A separate nipping and welding device 17 may be provided to assist in sealing and separating the containers.

Title: Amplifier
IPC: H03F3/183
Filed: 1968-06-10
Abstract: 1,214,918. Amplifying circuits. THOMSONMEDICAL-TELCO. 10 June, 1968 [8 June, 1967], No. 27474/68. Heading H3T. In an amplifier, more particularly for electrobiological use with one or more R.C. interstage couplings, to prevent blocking upon everload  the resistors, e.g. R1, R2 in a push-pull amplifier are shunted by the source to drain paths of field-effect transistors Q4, Q5. These transistors are normally non-conductive and do not affect the time-constants of the R.C. circuits: upon overload of the amplifier, however a voltage is applied from a later stage of the amplifier, via an OR-gate comprising diodes D1, D2 to an auxiliary amplifier comprising transistors Q1, Q2, Q3. The output of this amplifier is applied to the gates of field-effect transistors Q4, Q5 causing them to become conductive and reduce the time-constants of the corresponding R, C circuits R 1 , C 1  and R 2 , C 2  respectively. Variable resistor R8 allows of adjustment of the level at which the field effect transistors Q4, Q5 come into operation, and the time for which they are conductive is determined by an R.C. network R9, C3 of which the resistor also is adjustable.

Filed: 1956-09-11
Abstract: 802,645. Electric heating resistance coatings. LIBBEY-OWENS-FORD GLASS CO. Sept. 11, 1956, No. 276191/56. Class 39(3) An electrically conducting glass unit comprises a glass surface having an electrically conducting film in contact with a fired-on metal flux electrode containing metallic antimony, an antimony compound, antimony alloy, or mixtures thereof. As shown, a glass sheet 10 has electrodes 11 formed by applying a metal flux in liquid form and heating the sheet to approximately softening point for firing purposes, the sheet being then sprayed with a filming liquid, e.g. stannic tetrachloride, which reacts with the hot glass to form a conducting film 19. The metal flux may consist of 65.6 per cent silver, 7.8 per cent flux, 18 per cent organic binder, and 8.6 per cent thinner, and the antimony, which is added before firing, may be in the form of antimony dust, antimony trioxide, antimony trisulphide, or an alcoholic solution of triphenyl stibine. The amount of added antimony is preferably about 5 per cent. The antimony is said to eliminate the high resistance interface between electrode and film, believed to result from the presence of chlorides, and to prevent breakdown due to arcing.

Abstract: 887,680. Purifying gases. METALLGESELLSCHAFT A.G. Aug. 17, 1959 [Jan. 16, 1959], No. 28082/59. Drawings to Specification. Class 55 (2). In the detoxification of town gas containing carbon monoxide, nitrogen oxides and gumforming constituents by the catalytic conversion of the carbon monoxide in the presence of steam at elevated temperature over an iron oxide catalyst the catalyst is prevented from being fouled by nitrogen oxide gums and/or their decomposition products by arranging in advance of the catalyst a preliminary catalyst containing cobalt and molybdenum in " sulphured form," the period of contact of the gas, which is pre-heated to 300-450‹ C., preferably 350-400‹ C., being adjusted so as to remove any oxygen or nitrogen oxides before the gas comes into contact with the iron oxide catalyst. " Sulphured form " relates to the conversion of a molybdenum or cobalt salt into initially the corresponding oxide and subsequently the corresponding sulphide. Preferably the preliminary catalyst contains 10-20% by weight of molybdenum oxide and 2-5% by weight of cobalt oxide and is contained in at least two vessels, each of which can be independently connected to a system for regenerating the catalyst which it contains. Reactivation of the preliminary catalyst may be effected by exposing it to sulphur or a compound thereof, while the iron-oxide catalyst may be regenerated by oxidation, followed by partial reduction.

Filed: 1974-06-25
Abstract: 1476507 Counting sheets GLORY KOGYO KK 25 June 1974 [28 June 1973 31 Oct 1973] 28082/74 Heading G4D [Also in Division B8] A sheet counting apparatus has means 2 for receiving a stack of sheets, e.g. banknotes, to be counted and urging them towards two feeding rolls 50, 51 which are driven intermittently to separate single sheets from the stack past a count sensor 56 to a conveyer 5 which restacks them beneath a rising plate 201. The lower feeding roll 51 is continuously driven during counting and has a member of friction surfaces able to drive the roll 50 through an intermediate roll 55 and to drive the sheets, the rest of the surface being smooth and/or cut away. The roll 51 initially drives only roll 50 which thus causes the upper edge of the first sheet to move downwards, the sheet bowing out away from the next sheet; then the two rolls 50, 51 drive the sheet in unison and finally the upper roll 50 is braked and serves to hold the next sheet while the first is taken away by roll 51. The sheet passes through the gap between roll 51 and a plate 13, which is adjustable at 74 to set the gap to the sheet thickness, and then between the roll 51 and a sensing roll 56 on a lever 102; the sheet depresses roll 56 tilting lever 102 and operating a microswitch 103 which feeds an electric pulse counter (not shown). Should more than one sheet pass the separating mechanism a second switch 102 is operated by the extra thickness and this operates a stop motion: a solenoid 300 is energized to move a linkage 302 which moves a small roller (308) against the bottom of the stack to push it away from the feeding rolls. During normal operation the small roller (308) is oscillated against the sheet, to assist the separation, by a cam (305) on shaft 58 of the roll 51. The conveyer 5 moves the sheets against a stop 265 and a star wheel 156 lifts the trailing edge so succeeding sheets pass beneath. An adjusting knob 250 moves the stop 265 and also a guide (257) (Fig. 7, not shown) alongside the stack S to allow for different denominations of banknotes.
