Inventor: IFIELD RICHARD JOSEPH
IPC: F02D1/00
Filed: 1964-10-05
Abstract: 1, 131, 511. I.C. engine valves. JOSEPH LUCAS (INDUSTRIES) Ltd. Nov. 23, 1965 [Oct. 5, 1964], No.40399/64. Heading F1B. Multi-cylinder I.C. engine-liquid fuel metering apparatus comprises a member 21, Fig. carriedby a rotor, 12, mounted within a body, the rotor, body and member defining a chamber 20 the volume of which is varied by control means, the body having at least one fuel inlet passage 14, a plurality of fuel-outlet passages 16 and a plurality of air pressure admission passages 18. As the rotor rotates the or each chamber communicates in turn with an inlet passage and then with an outlet passage and simultaneously with an air pressure admission passage thereby expelling fuel through an outlet passage. During filling of chamber 20 excess fuel is spilled through passage 17. The volume of chamber 20 is varied by means of a rotatable plate 22 which is linked to the throttle by a mechanism 27 (not described). Rotation of plate 22 causes balls 25, which are engaged in an inclined groove 24, to move plate 22 axially to  vary the axial position of member 21. The inner end of member 21 may be recessed.  In another embodiment, the rotor (12), Fig. 3 (not shown) has an annular extension with teeth which engage teeth on a flange (37) of a shaft 13. The axial position of the spring-loaded piston is varied by means of a spring-loaded pivoted lever (33) which is moved by a shaft (30) engaged with the lever 33 through a part-spherical bearing (31). Shaft (30) passes co-axially through the wall of the body opposite to the driving shaft (13). In a further embodiment sleeves 40, 41, Fig. 4 are splined together so as to define variable volume chambers 43 arranged about the rotor axis. Axial movement of one sleeve varies the volume of the chamber. The sleeves 40, 41 rotate about a stationary cylindrical member 45 which includes an air passage 46 communicating with peripheral recesses 47. A further open-ended peripheral recess 48 communicates with the fuel inlet passage 50. When a sleeve chamber 43 communicates with recess 48 it is filled with fuel and excess fuel is spilled via passages 52 in the body 42. Continued rotation brings the chamber 43 into communication with recess 47 and pressurized air expels the fuel through outlet passages 51.

Title: Method of recording information in digital form
IPC: H03M7/30
Filed: 1974-09-20
Abstract: 1478686 Recording data MATSUSHITA ELECTRIC INDUSTRIAL CO 20 Sept 1974 [20 Sept 1973] 40996/74 Heading G4C [Also in Division H4] Variable-length data words are recorded on a recording medium having a plurality of unit memory divisions such that each word is recorded on one or more unit memory divisions depending on the length of that word. A picture original 39, Fig. 3 is scanned to produce from phototubes 62, 64, 66 and 68 white, red, green and blue signals. The red, green and blue signals are digitized at 70, 72 and 74 the resulting outputs being fed to a multiplexor 76 each output word of which represents a detected colour and is passed via an interface 78, computer 86 and interface 90 to a magnetic recording head 92 to be recorded on a magnetic tape 60. Also recorded on the magnetic tape 60 with each colour representative word is a duration signal representing the number of scanned picture elements of the respective detected colour, derived from a counter 82 receiving the output of a sampling circuit 80 connected to phototube 62, the counter 82 being reset at every change in the output of multiplexor 76. The magnetic tape 60 has a track 110 for parity checking and eight tracks 112-126 for recording information. If the duration signal is 7 or less, the colour representative word is recorded in tracks 112-118, the duration signal is recorded in tracks 120-124, and a "0" is recorded in track 126. If, however, the duration signal is greater than 7 the colour representative word is recorded in tracks 112- 118 of one byte, a "1" is recorded in track 126 of that byte and the duration signal is recorded in tracks 120-124 of that byte and tracks 112-124 of the next byte, a "0" being recorded in track 126 of this next byte. A comparator 88, Fig 3 determines whether the duration signal is greater than 7. Three bytes may be available for storing each item of information. The magnetic tape 60 may be replaced by a paper tape or a card.

Title: Improved process and apparatus for the separation of solid particles from fluids
IPC: B01D45/02
Filed: 1965-09-28
Abstract: 1,112,309. Separating solids from gas or liquid; cyclone separators. M. BERZ and W. BERZ. 28 Sept., 1965 [29 Sept., 1964; 17 May, 1965; 28 July, 1965], No. 41148/65. Headings BID, BIT and B2P. A gas or liquid is cleaned of entrained solids by passage through a bed of filtering material, such as gravel, the gas or liquid being delivered on to the upper face of the filtering bed while undergoing rotational motion, so as to impinge on the bed at an angle of 5 to 50 degrees. In Fig. 1 the bed 3 is located in what is basically a cyclone separator from which clean gas leaves by duct 6. An airlock and screw conveyor 9 remove deposited dust which has penetrated bed 3, and periodically damper 7 is closed and bed 3 cleaned by reverse flow gas delivered to chamber 4 and leaving by conduit 8, to waste or separate cleaning and return to inlet 1. In Figs. 2, 3 (not shown) the gas is cleaned in a separate cyclone separator and delivered, still rotating, down a connecting conduit to the filtering bed. In Fig. 2 a blower (110) downstream of the bed (107) delivers reverse-flow gas via vanes (113) so that it too enters the bed, from below, rotating. The reverse flow gas is then delivered to a depositing chamber or filter (114), or returned to the inlet side of the cyclone separator (102), or delivered by the filter bed inlet conduit (104) back to cyclone separator (102) through its outlet, which has vanes (105) which serve to swirl the reverse flow gas and similarly to impart rotation to gas flowing out of the cyclone through conduit (104) to the filter. Fig. 3 shows a cyclone separator with an adjustable shutter (126) on its inlet and a vertically adjustable outlet pipe (124) with vanes (125), whereby maximum efficiency of the cyclone and maximum swirling of the outgoing gas en route to the filter are achieved. In Fig. 4 (not shown) gas passes from the cyclone (304) to a housing above containing two filter beds (302, 303) and while some gas passes downwards through both beds in series a variable quantity is delivered by tangential, closable apertures (311) to the space between the beds and passes through the lower bed only. A rotatable hub tube (308) carries members (309, 310) for smoothing the beds after reverse flow cleaning. In a modified arrangement (Fig. 5, not shown) rotation of the gas between the two beds is induced by supply of clean gas from an auxiliary central tangential inlet (321). The filter beds may be fibrous material supported only below or may be replaced by gratings, sintered or felted sheets. Gas rotation may be enhanced by rotary vanes and filter elements may vary in porosity over width and thickness.

Title: Regenerative heat exchanger with heat-retaining mass movable in counter-current to the heat exchanging media
Inventor: GETTO ARTUR
IPC: F28D19/04
Filed: 1961-11-17
Abstract: 1,012,434. Thermal regenerators. SVENSKA ROTOR MASKINER A.B. Nov. 17, 1961, No. 41199/61. Heading F4K. In a rotary-matrix counter-current flow regenerative heat exchanger having a heatretaining mass arranged within the rotor in arcuate sectors which are separated by damper elements controlled according to the position of the rotor, and are traversed successively by the heat imparting and heat-absorbing media in a direction opposite to that of the rotor, at least one intermediate connection is provided between the respective inlet and outlet connections for one or both of the media. The heat-retaining mass may consist of a series of coil springs 16, Fig. 4, or sets of sheet metal plates 17, with spacing members on wart-like projections, or corrugated sheet metal plates 18. The damper elements 2<SP>1</SP>, Fig. 1, are governed such that they always form shields 2<SP>11</SP> dividing the heat-retaining mass into two channels 1, one traversed by the heat imparting medium from an inlet 3 to an outlet 4 and the other by the heat-absorbing medium from an inlet 5 to an outlet 6. Between these connections are provided the intermediate connections 7 and 8, one 7 in the heat imparting medium channel to accept a partial stream of lower temperature medium roughly coinciding with the reduced temperature of the medium already flowing through this channel and the other 8 in the heat-absorbing medium channel to exhaust a partial stream of moderately heated medium. The sequential operation of the damper elements can be effected by mechanical means such as a stationary cam 25 or may be controlled by pneumatic, hydraulic or electrical means or may be effected automatically by counterweight. The rotor may be driven from friction rollers 14 which support the construction, or from a central shaft 15. To direct the flow of heat imparting medium from the main inlet towards the hub of the rotor the inlet connection 3<SP>1</SP>, Fig. 2 (not shown), can be mounted radially and contain guide vanes, also the outer damper elements can be kept closed in the zone adjacent the outer periphery of the rotor within the channel until the intermediate connections 7 or 8, Fig. 1, has been reached. The rotor can be divided into two axially adjacent sub rotors, Fig. 5 (not shown), which are separated by sealing means and in which partial streams of at least one of the heat imparting or heat absorbing mediums are admitted. The sealing between rotor and casing can be effected either by sprung slip-rings 19, Fig. 4, or by asbestos cord 21 held in place by springs 22.

Abstract: 1,185,129. Weighting warp thread. TEXMA MASCHINEN G.m.b.H. [trading as GEBR. SUCKER]. 29 Aug., 1968 [7 Sept., 1967], No. 41246/68. Heading D1L. In the weighting of a warp thread band F by continuous passage through a dressing solution 1 and squeeze rolls 4 with subsequent drying, the quantity of solution absorbed is decreased from an initially high value in two stages by (a) increasing the pressure of the rolls to its optimum value while the concentration is maintained constant at an elevated value and (b) decreasing the concentration while the pressure of the rolls is maintained constant at the optimum value, the end of each stage being determined by measurement of the quantity of solution absorbed. Each stage may be terminated manually or automatically. The solution is recirculated to the treatment bath via a reservoir la which is automatically topped up from a tank 9 when a lower level is reached, the number of revolutions of a roller 3 between topping up operations indicating the quantity of solution absorbed. A desired concentration is made up in tank 9 from concentrated solution in a tank 11 and diluent from a line 12. The concentrated solution is first passed in up to the level of a probe 20 and diluent is then passed in up to the level of a device 18. Variation in the height of the probe alters the concentration of the solution produced in tank 9.

Filed: 1972-09-06
Abstract: 1378224 Data processing systems WESTERN ELECTRIC CO Inc 6 Sept 1972 [9 Dec 1971] 41250/72 Heading G4A In response to a predetermined "request" instruction acted on by a processor P1, an event correlator 21 constructs a diagnostic data word from information contained in that instruction and information representing parameters of system operation. In the example shown, correlator 21 monitors the op. code and address of each instruction to detect match with a predetermined op. code and address signifying a request instruction. If a request instruction is identified, data representing system time and a successively incremented address of an area of buffer storage are gated to a register R2. Data representing the identity of the program and the location in the program of the request instruction is gated directly into register R2 from processor instruction register R1. The match signal 24 alerts memory controller 12 to store the data in register R2 at the new address specified. An I/O operation may be initiated when the buffer area has been filled or new diagnostic words may be stored in place of those previously stored. In a system containing more than one processor, additional data identifying the particular processor acting on a request instruction may be included in the diagnostic word. The arrangement enables information concerning the use of software instructions by hardware devices to be obtained with minimum disturbance of system operation.
