Title: Improvements in and relating to gas producers, with means for utilizing waste heat
IPC: C10J3/00
Filed: 1920-11-29
Abstract: 176,113. Koppers, H. Nov. 29, 1920. Producers. - The lower part of a gasproducer or a series of producers is provided with a cooling- jacket e communicating by pipes f, g with the bottom and ends respectively of a drum h positioned at a higher level than the producer jacket, so that a certain pressure is exerted on the water in the jacket to prevent evolution of steam therein by raising the boiling-point of the water and to cause steam to be given off under reduced pressure from the water in the drum h. This steam passes from a dome i by pipes k for use in the gas-producer. Two or more producers may be used in connection with a single drum h and a cooling liquid other than water may be employed, the temperature of the jacket being sufficiently high to superheat the air and steam supplied to the producer and prevent condensation on the wall of the jacket.

Abstract: 843,184. Fluid-pressure servomotor-control systems. VITS, H. Nov. 6, 1956 [Nov. 8, 1955], No. 33827/56. Class 135. [Also in Group XVI] An electric motor drives the rotor 3, Fig. 2, of a variable-displacement pump which feeds a variable-displacement motor, the rotor 4 of which drives a web 37, Fig. 3, via rollers 6 and a belt drive 5a. The pump and motor casings are connected by pins 8, 13, Fig. 2, to pistons 11, 14, whilst springs 15, 16 hold the pump and motor in the zero delivery and maximum intake positions, respectively; the pistons 11, 14 abut diaphragms which each define one wall of chambers 20a, 20b that lead to a hollow body incorporating valves 18, 19, Fig. 3, controlling the inlet to, and exhaust from, the chambers of pressure liquid, e.g. water. The valves 18, 19 control the pressure in the chambers 20a, 20b, Fig. 2, and hence the eccentricity of the pump and motor, and the web speed; the springs 15, 16, which oppose the chamber pressure, are of different ratings so that for a given pressure the pump adjustment is different from that of the motor. Upon rocking a link 24, Fig. 3, to one side or the other of a mid-position in which valves 18, 19 are closed, either one or the other of the latter is opened, the degree of opening determining the rapidity at which the drive speed will change. The link 24 is pivoted upon a control member 28 in turn pivoted upon a floating follow-up lever 27, Fig. 2, with its longer arm supported by the piston 11 and its shorter arm by piston 14, the member 28, Fig. 3, being attached to a diaphragm 29a connected by an hydraulic link to a further diaphragm 33 operated by a lever 34a on an idler 34 over which passes the web 37 in its passage to rollers 39; if the latter causes slacking or tensioning of the web the idler 34 is lowered or raised to actuate the valves 18, 19 and adjust the speed of the rollers 6. The direction of feed may be reversed and the diaphragm replaced by pistons. A number of motors may be supplied by one pump and the hydraulic link may be replaced by a mechanical arrangement.

Title: Improvements in or relating to Vehicle Signalling Systems
IPC: G08B5/38
Filed: 1967-07-26
Abstract: 1,198,999. Vehicle flashing indicators. PAL NARODNI PODNIK. 26 July, 1967 [27 July, 1966], No. 34271/67. Heading G4Q. [Also in Division H1] A vehicle signalling system includes a threeposition switch such that in position (1) the flashing direction lights work normally, in position (2) an auxiliary relay causes the lights on both sides to flash simultaneously and the ignition circuit is broken, and in position (3) the ignition circuit is re-made without altering the flashing light connections from the arrangement of position (2). In Fig. 2, with the switch in its normal position current flows from the vehicle battery 21 through flasher unit 24 and terminals 1 and 2 to the direction indicator switch 251. When this is operated to one side or the other the corresponding direction lights 28 or 29 flash, together with repeater 253 or 254 and, if fitted, trailer light via connection 27. At the same time terminals 8 and 9 are bridged to energize the engine ignition coil 26. If the vehicle should break down on the road, the button 11 is rotated to break connections 1-2, 8-9 and thus stop the engine. Current now flows from the battery to terminal 5 to operate an auxiliary relay (electromagnetic or semiconductor) whereby terminal 1 is connected to 3, 4 and 7 to flash all the direction lights simultaneously and also a repeater 281. The engine may be tested by pressing in the button 11, whereby terminals 8 and 9 are bridged without disturbing the other connections. A similar switch unit may be used with a currentindependent double circuit flasher. The construction of the switch unit 20 appears in Fig. 1 (not shown, see Division H1).

Patent GB-819134-A (GB)
Title: Improvements in or relating to electro-magnetic devices
Inventor: KILBURN TOM
IPC: G11C11/06
Filed: 1954-11-26
Abstract: 819,134. Magnetic storage devices. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 17, 1955 [Nov. 26, 1954], No. 34383/54. Class 38 (2). [Also in Groups XXXVIII and XXXIX] An electromagnetic device comprises a magnetic flux circuit defined by a first and a second body of magnetic materials, the first of which has a high retentivity characteristic whilst the second has good electrical conductivity, the reluctance of the magnetic flux circuit being alterable by magnetically saturating the second body by virtue of the passage of an electric current therethrough. A magnetic flux circuit as shown in Fig. 2 comprises a loop 27 of highly retentive magnetic material having a relatively high ohmic resistance, the opposite sides of the loop 27 being bridged by a magnetic shunt 28 of magnetic material having low retentivity and low ohmic resistance. The shunt 28 is arranged to be in good flux transfer relationship with the loop 27 but to be electrically insulated therefrom. Whilst no current flows through the shunt 28 a winding 32 on the part 27b of the loop is able to effect a write input, the part 27a of the loop remaining unaffected. When it is desired to obtain a read-out from a winding 31 in the part 27a of the loop, a switch K<SP>2</SP> is closed whereby direct current flows through the shunt 28 thereby saturating it. When saturated the shunt 28 becomes ineffective magnetically, thus the loop 27 becomes effective as a whole to give a read-out on the winding 31. Non-destructive read-out may be obtained by passing alternating current through the shunt 28. In the embodiment shown in Fig. 3 the magnetic flux circuit comprises a first U-shaped member 34, the ends of which are bridged by a second U-shaped member 35 through one or both arms of which current is passed according to the manner in which the device is required to operate. In order that the device may function as a recording head a small air gap may be provided in either the member 27 or the member 34. The Provisional Specification describes also magnetic flux circuits wherein the magnetic member has different cross-sections or in which the currentcarrying portion is non-magnetic and surrounded by the magnetic portion or in which the magnetic member is in the form of a figure 8 the common part of which saturates in operation, but in no part of which member is current arranged to flow. A matrix is also shown made of such figure 8 shaped members. Specifications 814,941, [Group XXXIX], and 814,942 are referred to.

Title: Improvements in or relating to a process of and apparatus for rectification and distillation by centrifugal separation
IPC: B01D3/14
Filed: 1937-12-14
Abstract: 507,435. Stills ; multiple - effect apparatus; distilling alcoholic liquors. LOUMIET ET LAVIGNE, J. Dec. 14, 1937, No. 34632. Convention date, Dec. 19, 1936. [Class 32] Liquids are distilled and rectified by causing their vapours to flow through helical coils with a velocity sufficient to develop a component of centrifugal force several times as great as gravity, injecting rectifying liquid into the vapours and causing it to be atomized, and extracting the rectified liquid. The coils may have straight portions. In a double-effect apparatus, Fig. 15, for the rectification of alcohol &c., the distilland is heated by steam pipes in a boiler E and the vapours pass with the requisite velocity up a rectifying column R formed by winding a helical floor between two concentric cylinders. Unvaporized residue leaving the boiler E serves to heat the feed of distilland entering by pipe A and passing through pipes al ... a<6> to the column. The vapours reaching the top of the column pass by pipe L<1> to a separator-condenser.coil S, of the type described in Specification 490,703, the heat of condensation serving to boil the distilland for the second effect. The condensate separated centrifugally in the upper convolutions S<1>... S<6> is returned as reflux to the upper part of the column R, the pure distillate being drawn off by a pipe F. Condensate separated centrifugally from each turn of the column R is passed back as reflux six turns lower in each case, the condensate from the lowest six turns being passed by pipe p to the boiler E. The second effect is substantially of the same construction, but works at a lower pressure; the distilland enters by pipe A<2>, flows through tank T<1> containing the separator-condenser coil Sa, and is preheated at Cx by residual liquid leaving the boiler T by pipe p<5>. The distilland enters the column R<11> by pipes a<7> ... all. The reflux from the lowest turns of the column is circulated by a pump B to the boiler T, from which the vapours pass by pipe L<2> to the foot of the column. The lower half of the coil Sa is cooled with water. The columns R, R<11>, instead of being built up as described, may be made from a helical coil of tubing of a: crosssection such as that shown in Fig. 8, the elongated part 8a on the outer circumference of the helix forming a channel for the separated liquid or preferably being roughened to provide 'a heating effect as in Specification 500,942. In a modified form of column, the helix is arranged in sections so that the vapours flow downwards within each section, but upwards through the column as a whole. Alternatively, the column may consist of flat helices placed one above the other, Figs. 17 and 18. Modifications of this form are described. Specification 447,457 also is referred to.
