IPC: F24C15/02
Filed: 1937-05-04
Abstract: 472,535. Kitchen ranges. EISENWERK G. MEURER AKT.-GES. May 4, 1937, No. 12733. Convention date, May 16, 1936. [Class 126] In a kitchen range burning solid fuel only or solid fuel for general purposes and gas for roasting and grilling, a smooth front is obtained by providing, behind the front plate of the range, a plate or frame having flanges which project into the door openings and form abutments for the doors.

Filed: 1944-07-04
Abstract: 604,508. Drive of couch rolls of papermaking machines. BELOIT IRON WORKS. July 4, 1944, No. 12742. Convention date, May 20, 1942. [Class 96] [Also in Groups XXXV and XXXVII] The main suction couch roll 13 of a paper-making machine is driven continuously and drives the wire-cloth 11 and also an additional suction roll 15 to an extent dependent upon the degree of suction, and at a speed which may be greater than that of the roll 13, to allow for stretch of the wire-cloth. The roll 15 may be driven from a belt 26 travelling over a pulley 29 which tensions the belt in accordance with the suction in a chamber 33 which communicates with the suction box of the roll 15, a compression spring 39 also being used. Electromagnetic coupling may replace the belt 26 &c., the slip in an electromagnetic clutch being controlled, by a rheostat &c., in accordance with the pressure in the suction box of the roll 15. Alternatively an electric motor control system may be used, the roll 13 being coupled with a generator with field coils in parallel with the field coils of a motor driving the roll 15 and in series with a rheostat such that resistance is reduced as the suction increases; a continually driven booster generator &c. providing additional torque insufficient alone to turn the roll 15, but sufficient to avoid slipping when starting up.

Abstract: 1453580 Extruding and perforating corrugated tubes W HEGLER 26 March 1975 [20 June 1974] 12755/75 Heading B5A [Also in Divisions F2 and B1] A length of drain pipe formed of plastics material has an annularly or helically corrugated wall wherein water entry apertures are concentrated at zones spaced apart along the length of the pipe. Apparatus for moulding the pipe from a freshly extruded plastics tube (Fig. 7) comprises two trains of interlinked half moulds 16 forming the moulding cavity into which the pipe issues from a mouthpiece 20 over the mandrel 21 of an extruder. Air is then evacuated at 17 to draw the pipe into grooves in the mould wall to form the corrugations. An extension 22 of the mandrel 21 carrying crowned rollers 23 is screwed to the mandrel such that the rollers 23 operate to press the still hot plastics pipe against a cylindrical mould 18 to form longitudinal ribs separated by comparatively thin walled grooves. Knife blades 28 mounted on a locating tube 25 of the mandrel extension 22 serve to cut the longitudinal apertures in the pipe.

Filed: 1950-05-22
Abstract: 688,644. Burglar alarms. E.M.G. HAND MADE GRAMOPHONES, Ltd. May 11, 1951 [May 22, 1950], No. 12824/50. Class 118 (i) [Also in Groups XXXVI and XL(c)] Burglar alarm apparatus comprises a radio transmitter to maintain an electro-magnetic field in a space to be protected, one or more receivers at spaced. points to develop a voltage from the field, and circuit means to operate an alarm when the rate of change of this voltage exceeds a predetermined value, the wavelength being between ¢ and 3 metres, and the circuit having a time constant between .25 and 5 seconds. Fig. 1 shows a radio transmitter operating at 300 Mcs., comprising a tank circuit 11 and valve 10, the high frequency oscillations being modulated at an audio frequency by means of modulator 22. Fig. 2 shows the receiver in which a loop 17 of small diameter compared to the operating wavelength is used to pick-up the os, cillations which are detected by crystal detectors 19, 20, the resulting audio frequency being amplified by valve 25 and then detected by detector 26. The voltage, from detector 26, which is dependent upon the amplitude of the modulation frequency is applied to a condenser-resistance network 27, 29, which has a time constant of the order of 1.2 seconds, so that a voltage is applied to a further valve 30, only when the rate of change of signal voltage exceeds a predetermined amount. The output from valve 30 is applied to a cathode follower valve 31 the output of which is applied through a condenser of large value (e.g. 300 microfarads) to a relay device 33 which is used to operate an alarm bell. The alarm is thus operated only when relatively quick movement of a sufficiently large object occurs, to produce a sufficient rate of change in the value of the received signal, while slow changes in the signal due to atmospheric or other causes, do not result in the operation of the alarm. A plurality of detector units comprising the loop 17 and detector element may be provided, and some may be connected to the opposite half of the input winding of transformer 24 to produce a balanced input to valve 25 under normal conditions.

Abstract: 1,243,495. Transformers. INTERNATIONAL STANDARD ELECTRIC CORP. 18 March, 1970, No. 13053/70. Heading H1T. A method for electro-static shielding of miniature transformers comprises placing an inner winding (2, Fig. 1B, not shown) on a toroidal ferrite core, coating the winding and core with an insulation, electroless coating the insulated structure with a conductive material, scribing a gap 6 in the conductive material, electroplating the scribed structure with copper 7, insulating, 9, the electroplated structure, and forming an outer winding 10 on said insulated and plated structure. A final insulating and protective epoxy coating (12, Fig. 1H, not shown) is placed over said outer winding and thereafter cured. The electroplating step includes the step of securing a grounding tab 8 to the copper plating. The electroless coating material may be an electroless copper plating on which, after drying, is scribed the gap which prevents a shorted arm effect in the transformer. The insulated structure may be coated with a conductive material by means other than electroless plating means.

IPC: B01J2/26
Filed: 1961-04-13
Abstract: <PICT:0950510/C1/1> Granular uranium oxide product (UO2 with or without UO3 and/or U3O8) is prepared by forming a layer of an aqueous paste of uranium oxide or ammonium uranate, breaking the layer into lumps, heating the lumps sufficiently to dry their outer surfaces and thereafter heating the lumps more strongly to obtain completely dry discrete granules of the uranium oxide product.  As shown in Fig. 1 a layer of ammonium uranate paste 12, formed on rotary filter drum 4 by the movement of the drum through bath 11 of a fluid paste of ammonium uranate, is removed from the drum and broken into a multiplicity of lumps 30 by scraper 13.  The lumps fall through channel 14 on to endless conveyer 1 and are heated to a temperature ranging from 150 DEG  to 250 DEG  C., to form on their surface a dry outer layer, by coil 5 which is supplied by with combustion gas from heating apparatus 7 via conduit 6.  The lumps are passed from conveyer 1 to conveyer 15 which is perforated to permit the passage therethrough of hot air.  The air circulates in a generally counter-current fashion with respect to the movement of the lumps 30 on conveyer 15, and heats the lumps to a temperature ranging from 350 DEG  to 400 DEG  C. There is obtained at the delivery end of the conveyer 15, at 19, a porous granular uranium oxide product having a good mechanical resistance.  Specifications 800,692 and 885,217 are referred to.
