Title: Layerized high dielectric constant piece for capacitors and process of making same
IPC: C04B35/468
Filed: 1950-03-21
Abstract: A ceramic dielectric is composed substantially of an alkaline earth titanate or mixture of such titanates and a reducing activator and is layerized by firing under conditions whereby one portion is oxidised whilst the other is reduced.  The reducing activator comprises a rare earth oxide or mixture thereof or thorium oxide, in an amount not exceeding 5 per cent by weight. The firing may be in one step or more.  If in one step, by firing in an oxidizing atmosphere with a portion of the mixture on a carbon mass.  If in two stages, by firing in either a reducing or oxidising atmosphere and then refiring in an oxidizing atmosphere whilst over a mass of carbon.  An alkaline earth firconate may also be present e.g. of barium.

Title: Improvements relating to the treatment of combustible material
IPC: F23K1/00
Filed: 1928-03-06
Abstract: 312,707. Petersen, H. P. March 6, 1928. Fuel, feeding.-Combustible material such as coal is pulverized and dried in a mill 1 through which there is induced bv a fan 11 a current of hot gaseous products drawn from the furnace through a pipe 7, this current serving to convey the pulverized, material by a pipe 9 to a separetor 2 from which the coarser particles pass into a hopper 13 while the combustion gases and fine dust are drawn through a pipe 14 into the fan 11 and are ejected by the fan into a mixing pipe 15. A worm 17 conveys the material from the hopper 13 to the mixing pipe 15 whence it is delivered, by the blast from the fan 11, into the furnace 3 through a pipe 16. Adjustable openings 18 in the furnace wall supply the air for combustion. The combustion gases to be returned to the mill are drawn from either or both of two pipes 22, 23 in front of and behind the economizer 19, the supply being regulated by valves 24 so that the temperature of the drying gases may be adjusted. The mill 1 is mounted on hollow trunnions 5, 6 and is fed from a hopper 8.

Abstract: 492,180. Sliding - clasp fastenings. CORNER, G. H. C., BRITTON, E. E., and LIGHTNING FASTENERS, Ltd.. March 15, 1937, No. 7578. [Class 44] The slider of a sliding-clasp fastener is locked in the top position by means of locking arm 11 mounted therein and having a locking head 20 of greater dimension than the spacing between the fastener elements so that such head can only engage in a space 8 provided below the top stop 7 or between the two pairs of clamping arms of such top stop. The space may be obtained by removing the uppermost fastener element of an ordinary fitted stringer tape ; a ferrule 9 is provided around the beading at such point to prevent fraying and to prevent the slider slipping off. The locking arm is pivotally mounted beneath the bridge piece 17 for the pull tab 22 and is pressed downwardly by a rubber plug 21, the pivotal mounting being given by threading an apertured end of the arm over a stud 13 and engaging the end 14 of the arm in a recess 15 in the lug 16 to which the bridge piece 17 is fixed. The locking lug is arranged at the broad end of the slider when it is to engage between the two pairs of clamping arms of the top stop.

Title: Improvement in or relating to devices for removing accumulated solid matter from strainer gratings
IPC: E02B5/08
Filed: 1936-03-13
Abstract: 459,756. Strainers. NYEBOE & NISSEN AKTIESELSKABET, 10, Emi1 Chr. Hansens Vej, Copenhagen. March 13, 1936, No. 7657. Convention date, March 19, 1935. [Class 46] Solid matter is cleared from a bar screen 5, Fig. 1, by the prongs 3 of a rake mounted in a frame 1 which is guided for up-and-down motion by rollers 8, 9 travelling respectively in guide rails 6, 7. At a point above the screen the guide 7 has an outwardly bent portion 7<a> into which during ascent of the frame the rollers 9 are directed by a pivoted and counter-weighted member 10, so that the prongs are brought into engagement with a scraper 13, pivoted on an axle 14, and the scraper removes the solid matter from the prongs causing it to fall into a trough B. During downward motion, the rollers 9 keep to the vertical portion of the guide and push the member 10 aside. The frame 1 is drawn upward by a rod or rope 4 attached to a weighted arm 17, Fig. 3, fixed to a ratchet wheel 16 which is fixed on a shaft 15 in the frame. The shaft 2 to which the prongs 3 are attached is connected by rods 29, 26, to a lever 23 pivoted on the shaft 15 and carrying a pawl 24 which engages in a recess in the periphery of the wheel 16. The prongs are thus held in the position shown in Fig. 3 as the frame rises. On descent of the frame, the outer end 30 of the pawl engages a stop 31, so that the pawl is withdrawn and the weight of the rod 26 causes the prongs 3 to turn about the axle 2 into a vertical position so that they do not engage the bars of the screen as they pass down in front of it. Rotation of the shaft 15 is limited by arms 19, 20, fixed to the shaft and engaging stops 21, 22. Specification 244,946, [Class 46], is referred to.

The printing units of one set (1, 2, 3, 4) may be driven by a combination of motors including some from another set of units (5, 6, 7). The motors M are of the variable speed induction type and are controlled by push button controllers such as are described in Specification 354,155, [Group XXXVII]. As shown in Fig. 2, the primary windings of the motors M are connected by a switch 25 to the lines L<SP>1</SP>, L<SP>2</SP>, L3 for supplying current of normal 30 cycle frequency when it is required to drive the units at starting, inching, or normal speed, but when the web is to be threaded the switch 25 is operated to connect the motor M to a low frequency generator 24 driven by a motor 22 now connected to the lines L<SP>1</SP>, L<SP>2</SP>, L<SP>3</SP>. More than two sets of presses and folders may be used, and as many motor generator sets 22, 24 are provided as there are sets of units.

[Classes 40(iii) and 40 (v)] The rectified video signal in a television receiver is transmitted to a cathode-ray tube 17 by a single amplifying valve 35, the circuits of which are designed to provide level stabilization as well as variable amplification. As shown in Fig. 1, the rectified video signal from a detector 15 is fed to the grid of the amplifying valve 35 by means of a condenser 44 and a grid leak 41, designed to make the valve act as a peak rectifier to stabilize the signal at the level of the peaks of the synchronizing pulses as shown by the curve 43. The input and output circuits of the valve 35 have a common adjustable resistance 40, producing negative feed back and thereby varying picture contrast. The control grid of the cathode-ray tube is connected to the anode of the valve 35, which is fed through resistances 37, 38 from a voltage source +B. The cathode of the cathode-ray tube is biased by a tapping from resistance 38 with byepass condenser 39. Specification 510,715 is referred to.
