Abstract: 464,926. Lubricating - pumps. JAKOBSEN, S. O. Nov. 18, 1935, No. 31911. [Class 102 (i)] A multiple-delivery lubricating-pump drawing from four reservoirs comprises a rotating cylinder block 23, carrying at its lower end a valve disc 14, and having four cylinder bores 24-27 with plungers such as 24<1>, 261. The cylinders 25, 27 communicate with the periphery of the valve by means of passages 49, 51 and draw from a reservoir 1 through passages in the valve seating, and discharge through ports packed by spring-pressed bushes 70, to pipe connections 74. During each revolution of the valve disc the passages 49, 51 communicate each once with a port 80, which draws from a reservoir 8. This lubricant is discharged through a port 81 to a pipe connection 82. The cylinders 24 and 26 communicate by passages 48, 50 with the face of the valve disc. These passages draw through recesses 64, 63 from concentric grooves 58, 57, which are fed by reservoirs 7, 6. The passages 48, 50 discharge through ports 66, 65, which alternate with the recesses 64, 63. The valve disc carries tappets 22, which are engaged by teeth 47 on a disc 43 on the driving shaft 45, the valve disc being thus rotated step by step. A crank-pin on the disc 43 is connected by a link 42 to a pivoted frame 40 engaging a flange 31 on a sleeve 28, which is thus reciprocated. A perforated partition 32 in the sleeve engages collars 24<2> &c. on the plungers, and so effects the discharge stroke. The suction stroke of two plungers is effected by springs 37, 38, which engage heads 25<3>, 273 on the plungers. The stroke is arrested by screws 39, which are adjustable to vary the charge. The suction stroke of the plungers 241, 261 is effected by levers 33, 34, respectively, which are pivoted in the sleeve 28.

Title: Method and Apparatus for Separating a Coarse Fraction from a Pneumatically Conveyed Flow of Particulate Material.
IPC: B07B7/08
Filed: 1967-10-13
Abstract: 1,195,088. Centrifugal separators. MIAG MUHLENBAU UND INDUSTRIE G.m.b.H. 13 Oct., 1967 [22 Oct., 1966], No. 46766/67. Heading B2P. Pneumatically conveyed particulate material is classified into a coarse and a fine fraction by guiding the material by means of the conveying air against a screening surface at an acute angle, the material which does not pass through the screen being removed from the screen surface and reconveyed thereagainst at an acute angle, the conveying air flowing through the screening surface and entraining with it the fine particles, and the coarse particles being intercepted by the screening surface and discharged therefrom. A cylindrical screen 2 and a rotor 3 halving skewed impellers are mounted in a pressuretight casing 1. The rotor is driven through vee belting 8 by a motor 6. Below the screen 2 are a funnel 9 with a sight glass 10 and a bucket wheel air-lock 11. The air flow carrying the material to be classified enters the interior of the screen tangentially as at 12. The air and the light particles after passing through the screen are sucked via a tangential outlet as at 13 while the coarse particles drop into the lock 11. The impellers of the rotor 3 maintain the helical flow of the air and particles within the screen and prevent clogging of the screen by causing the formation of eddies which either force the fine material through the screen or entrain them upwards. The skewed orientation of the impellers is also responsible for ensuring that the material impinges at a greater acute angle on to the screen than if the impellers were disposed radially.

Abstract: 1396870 Electrophonic musical instruments J EVANS-PUGHE 10 Oct 1972 [15 Oct 1971] 48199/71 Heading G5J [Also in Division H3] A finger board for an electrophonic musical instrument comprises a plurality of discrete elongate conducting members connected in an oscillator circuit and manually displaceable elongate conducting means transversely overlying the conducting members, the conducting members being sufficiently close together that finger pressure on the conducting means may be continuously transferred from one conductive member to the next to vary the frequency of the oscillator circuit smoothly. The finger board has a fine tuning section 23, Fig. 2, corresponding to a single string of a violin &c., the section comprising a copper or beryllium-copper strip 2 overlying and separated from a plurality of copper or beryllium-copper contacts 13. Between each contact 13 is a resistor forming a chain connected between the terminals A, B of the circuit, Fig. 1, and arranged so that by shorting out different numbers of the resistor by tape 2, the player can select different frequencies from the emitter coupled multivibrator TR3-TR8. A further fingerboard 24 comprises a plurality of contact strips 14 overlaid by four pairs of non-touching strips 11. The lower strips of each pair are connected to terminal G, Fig. 1, and the upper strips are connected to terminal F through resistors. The strips 14 are connected through a logarithmic resistor chain to terminal E. When a player applies his finger to one of the strip pairs he first connects the strips together to set the basic frequency of the oscillator to one of four values a fifth or a fourth apart so as effectively to determine which string of a violin or double-bass, the fingerboard is to simulate. Further pressure brings the lower strip into contact with a selected one of strips 14 to turn on the output circuitry at a volume dependent on which strip 14 is engaged. Strips 2 and 11 are tensioned by coil or leaf springs or rubber bands in the box 9. The output is from two loudspeakers 12 series connected across terminals CD and located in an acoustic cavity 16 coupled to another cavity 17 having an opening 18 to simulate a recorder-like sound. There may be provision for an external loudspeaker, for waveform synthesizing or shaping and for a volume control. Power is supplied by batteries 25 and a control 21 (R3) is provided for tuning or transposing.

Abstract: 1,043,889. Forced flow steam boilers; recirculating combustion gases. SULZER BROS. Ltd. Dec. 6, 1963 [Dec. 21, 1962], No. 48345/63. Headings F4A and F4B. A steam generator in which flue gases are recycled through the space between the combustion chamber tube wall and a solid wall extending over at least part of the combustion chamber, consists of a vertical combustion chamber 1, Fig. 1 (not shown), fired by burners 35 and containing panel type superheating surfaces 8. Flues 7, 9 extend from the top of the combustion chamber and contain contact heating surfaces 31 . . . 34 for superheating, reheating and preheating. The chamber and flues are bounded by tube walls 2, 3, 10, 11 which are spaced from solid walls 4, 12, 13 forming spaces 30, 37, 38 respectively. A portion of the flue gases are drawn by fan 6 from the flue 9 and recycled via an annular duct 5, approximately half way up the combustion chamber, through the passages 30, 37, 38. The tube walls are thereby heated on both sides which considerably reduces their thermal stresses, further by varying the recirculation flow the combustion chamber flame temperature can be influenced. Gases passing downwards through passage 30 enter the combustion chamber through opening 41, between the bottom of the tube walls 2 and the top edge of the funnelshaped tube wall 3, and opening 42 in the bottom of wall 3 through which combustion air enters. Additional outlets of various sizes can be arranged in wall 2 to increase the area of mixing of flame and recycled flue gases. If the outlets are distributed over the entire height of the combustion chamber the hot flame gases can be prevented from touching the walls, thereby reducing the formation of S0 3  and the consequent cold corrosion. The solid walls may consist of a sheet metal skin and thermal insulation 25 and may be of circular cross-section particularly if the generator is operated at a pressure above atmospheric.

Abstract: 1,182,637. Measuring displacement. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 26 Oct., 1967 [29 Oct., 1966], No. 48692/67. Heading G4H. To determine the angular or translational displacement of a moving body an A.C. voltage is generated by a scanning disc the phase of this signal representing the displacement. Pulses at a reference frequency are fed via a gate 5 (Fig. 3), opened when a frequency divider 2 also fed with the reference pulses delivers an output signal, to a counter 3, the gate 5 being closed by negative-going zero crossings I m  of the A.C. voltage. The counter 3 is then counted either up or down to zero depending on whether its count is greater or lesser than half its capacity, these zeroizing pulses also being accumulated either positively or negatively in a further counter, the total count in which represents the phase of the A.C. voltage at the end of the preceding measurement. When the counter 3 has been zeroized a signal on lead 9 starts another measuring cycle with the next pulse from the frequency divider 2. To avoid errors due to variations in the speed of the disc a signal I v  representing its speed operates a switch S so that the contents of a counter 11 supplied directly with pulses from pulse generator 12 are transferred to a memory 13 which controls the pulse generator 12 in such away that the frequency seeks to assume a value such, that a zero count is stored in the memory.
