Title: Improvements in and connected with the supplying of combustible fuel to internal combustion engines
IPC: F02M17/04
Filed: 1923-08-09
Abstract: 224,294. Hughes, C. Aug. 9, 1923. Liquid-fuel supply.-The amount of liquid fuel supplied by a pump to an internal-combustion engine, burner, or like combustion apparatus is regulated in proportion to the amount of air supplied, or, in the case of an oil-fired steam generator, to the pressure of steam produced. Fig. 1 shows the induction pipe 1 of an engine, the supply of air through the pipe being regulated by a throttle 2. Liquid fuel is supplied by a pump through a pipe 3 fitted with a discharge valve 4, the stem of which is formed with holes as shown, through which the fuel is forced. The opening of the valve 4 is made dependent on the suction within the pipe 1 by means of a, diaphragm 8 or piston which is connected to a rod 5 bearing on the valve, and which is subject on one side to the pressure in the pipe 1, and on the other side to atmospheric pressure. The suction effect on the diaphragm may be varied by a screw adjustment 10 of the port 9 and by a similar adjustment 12 of an atmospheric opening 11. The resultant pressure on the valve 4 is further adjusted by means of a spring 15 and screw 18. In the application to burners of steam generators, the steam pressure is supplied to one side of the diaphragm or piston, so that when the pressure decreases, the supply of fuel to the air conduit is automatically increased.

Filed: 1972-05-04
Abstract: 1436117 Electric selective signalling KENT METERS Ltd 3 May 1973 [4 May 1972] 20785/72 Heading G4H Apparatus for reading data sources and for transmitting the data back to a remote interrogator comprises a route selector 2, Fig. 2, which, upon receiving a coded interrogation signal, establishes one of a number of possible paths for a subsequent signal, each selector output being connected to one or more reading circuits, Fig. 3, each connected to a data source. As described the apparatus conveys the readings of 256 meters at a remote station to an interrogator at a local telephone exchange: selector 2 has eight outputs each connected to an identical selector each of whose eight outputs is connected to four meter reading circuits (Fig. 1, not shown). An interrogation signal comprises three 8-bit FSK signals (two "route selection" and one "meter selection"). The telephone line L is connected to the first selector via a regulator module 1 containing means 120, 122 for energizing the apparatus and for detecting a voltage caused by use of the telephone TH so as to render the apparatus inoperative. The first signal passes via a squaring circuit 190 to an input register 170: bits 1-3 indicate that the signal is for "route selection" and enable gates 176 to energize circuit 172. Bits 4-6 then pass via a register 178 to a route decoder 193 to select one of the eight outputs thereof. The next signal passes via 190, path 195 and the chosen output of 193 to the next, chosen, selector and, as above, selects one of eight outputs from the corresponding decoder. The third signal passes through the two selectors to the corresponding four meter reading circuits, where it enters a register 170<SP>1</SP>. As before, bits 1-13 enable gates 176<SP>1</SP> and circuit 172<SP>1</SP>, bits 4-5 pass via a register 178<SP>1</SP> to be compared in a circuit 142 with bits AB identifying the meter. Identity is achieved in one of the four circuits: here, gating 146 and a counter 157 are energized. The BCD meter identity number (six 4-bit digits) is gated 180 to a data selector 152 (three digits at a time) and passed serially under the control of counter 157 to a tone generator 159: the resulting signal passes via a circuit 162 in molule 1 to the line L. Finally, the BCD meter reading is applied three digits at a time to selector 152 and tone generator 159.

Title: Light deflection system
IPC: G02F1/33
Filed: 1971-04-19
Abstract: 1309048 Lasers INTERNATIONAL BUSINESS MACHINES CORP 19 April 1971 [17 Feb 1970] 20974/71 Heading H1C [Also in Division H4] A light deflector comprises a plurality of surface wave transducers disposed on a surface of a crystal and a variable frequency electrical signal source able to be connected to any selected transducer to provide surface waves of a correspondingly variable frequency, so that a light beam incident on the surface is diffracted by the surface deformations through an angle determined by the acoustic wavelength and in a plane passing through the acoustic propagation direction. As described, the crystal is preferably piezoelectric e.g. c-cut ZnO or CdS which are acoustically isotropic, or LiNbO 3  or quartz having an anisotropy which must be compensated and the transducers are interdigitated metallic comb coatings on the crystal. In a first embodiment, the crystal surface comprises a semicircle of transducers disposed about a circular reflective coating which is deformed together with the crystal surface by the acoustic waves and functions as a phase grating. In a modification, the reflective coating is disposed on a surface of the crystal opposite to that having the transducers. In a second embodiment, the crystal is a right triangular prism having the transducers on its hypotenuse surface and a reflective coating on another side. Light incident on the third side is normally internally reflected to the reflective coating and back again to the source, but the acoustically induced deformations of the hypotenuse side frustrate the internal reflection and give a transmitted (and diffracted) beam at an angle determined by the acoustic frequency.

Abstract: 796,727. Knitting. NEBEL, M. July 19, 1954 [July 18, 1953], No. 21040/54. Class 74 (2). Of two part courses making up each course of a fabric in which all stitches are drawn to the front face, one part course consists of two threads a, g<SP>1</SP>, which, at alternate wales are knitted together in plating relationship and, at the intravening wales, are respectively tucked and floated behind the normal stitch loops; and the other part course is of two threads b, g<SP>2</SP>, which are similarly knitted together at the intervening wales and tucked and floated at the alternate wales. The component part courses may be staggered, Fig. 1, or superimposed, Fig. 2, along the length of the fabric. At selected wales, the thread a or b may be held and knitted in to form three thread stitches A/C, B/C, being there the plating thread. Weft threads S may be introduced. Differently coloured threads may be used. The fabric may be made on a circular machine having two groups of needles, each with its group of sinkerlike loop transfer members and the needles and members of the one group alternating with those of the other group. That part of the thread to be tucked is formed into a loop over a transfer member which is then withdrawn, holding the loop, out of the needle row until the loop is to be taken into the fabric. The longer loop required in the three thread stitches is formed by feeding the thread over two adjacent transfer members. In order that these longer loops may remain on the open latches, instead of being below them as in the formation of tuck loops, the transfer members on which they are held are of greater height.

A method of manufacturing filter-tipped cigarettes of the kind in which the filter tip includes an outer element and an inner element positioned between the outer element and the adjacent end of the cigarette, comprises the steps of supplying pairs of inner elements 20a, 20b, single sections of double length outer elements 35, and cigarette bodies 19a, 19b to each of successive transfers pockets 146 of a carrier drum 25 to form an axially aligned assembly of cigarette body, inner element, double outer element, inner element and cigarette body, joining the assembly with wrapping material and severing it at its mid point to form a pair of tipped cigarettes. Sextuple lengths of inner filter plugs 32 are fed from a hopper by a belt 40 past a knife wheel 66 having a pair of knives as 64 spaced apart by 120‹ making two cuts in each plug 32 to sever it into three double length plugs 33. After cutting, the plugs 33 are deposited in successive grooves 50 of a wheel 22a. As the wheel 22a rotates each double length plug is severed in two by a rotary knife 74, the two single filter elements 20a, 20b being then spaced apart by a guide 78. Outer filter plug elements 34 equal to nine double length plugs are fed from a hopper to a drum 90 where they are severed into three pieces 86, each equal to three double length plugs, by rotary knives 95, 96. The plug lengths 86 are then fed past a second knife wheel, having knives at 116 similar to the wheel 66, where each plug length 86 is cut into three double length plugs 35, to successive grooves 122 of a wheel 22b. Spaced cigarette bodies 19 are fed by a belt 23 to a transfer device 24 which transfers two bodies 19 to the two outside notched rings of a wheel 27, the double length outer filter plugs 35 being delivered to the inner ring of the wheel 27 by the wheel 22b. From the wheel 27 the assembly of two cigarette bodies and a double outer filter plug is transferred to an assembly drum 25. The assembly drum 25 also co-operates with the wheel 22a so that the spaced inner filter plugs 20a, 20b are transferred from the wheel 22a to the drum 25 between each cigarette body 19a, 19b and the outer plug element 35. Guides are provided adjacent the periphery of the wheel 25 to push each assembly into axially abutting relationship and each assembly is transferred to a further wheel 30, the assembly then being joined together by a wrapping strip and severed at its mid point to produce a pair of double filter cigarettes.
