Abstract: 732,022. Electrically heated clothes horses. WILSON & BATKIN PTY., Ltd. Aug. 6, 1953 [Nov. 20, 1952], No. 21747/53. Class 39 (3). [Also in Group XIV] A clothes horse comprises two main frames each formed of horizontal rails 1 carried by side members 2 pivoted together at 3 so that the rails on one frame can be spread from the rails on the other frame, and two electrically heated plates or casings 7 extend over the full width of the clothes horse. Each heater is carried by the lower portion of one of two subsidiary frames 4, which are pivotally suspended at 6 from the main frames and extend down and are pivoted together at 5, so that when the spread of the main frames 2 is altered, the spread of the lower parts of the subsidiary frames 4 and the distance between the heaters is altered in the same direction. The heaters 7 comprise metal plates with a casing 9 enclosing resistance wires on a refractory and are connected in parallel. As the main frames are spread further apart, the plates 7 become more horizontal to increase the area from which the hot air rises. The main frames rest on a horizontal surface and are interconnected at 6 by pivoted stay links 7A. The temperature may be varied by cutting out part of the resistance.

Title: Improvements in or relating to methods of treating hydrocarbon gas or the like
IPC: C07C47/00
Filed: 1928-07-30
Abstract: 295,356. Empire Gas & Fuel Co., (Assignees of Walker, J. C.). Aug. 10, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Natural gases, utilizing; gaseous mixtures.-Natural gas and like hydrocarbon mixtures (including gases from the thermal decomposition of coal, petroleum, and shale, which may contain olefines) are mixed with air, oxygen, ozone, or carbon oxides in sufficient quantity to form aldehydes and alcohols with some of the hydrocarbons such as ethane and higher hydrocarbons while leaving the methane unaffected and treated catalytically so as to obtain a gaseous product (after the removal of the oxidation products) of a uniform calorific power. The catalytic chamber may consist of a casing 63, Fig. 2, preferably lined with heatinsulating material 64 and having an inner chamber 66 containing the catalytic mass 70 upon a grate 72. The natural gas is supplied by a pipe 32 having an upturned end 68 opening above the catalyst. Air &c. is supplied by a pipe 34 and the treated mixture passes out by a pipe 44. The gas from a main 10 is passed through a dust-separator 12, meter 14, compressor 16, gasoline absorber 18 (if desired), pipe 28, heating coil 31, pipe 32, catalytic-chamber 42, outlet pipe 44, heat interchanger 30, condensing and absorbing apparatus 48, 50, and pipe 52. Air is added by way of a compressor 40, meter 38, and pipes 36, 34. From the pipe 52 the treated gas may be passed through the same cycle (with fresh gas) by pipes 58, 28, or through a pipe 60 to a second similar set of apparatus in which a further addition of oxygen is made, and so on as many tubes as desired, or through a separator 54 to the main 10 for use. The pressure may be 100-300 lbs. or more and the temperature in the catalytic chamber about 800-900‹ F. The temperature is controlled by means of a bye-pass 62 which controls the quantity of gas which passes through the heating-coil. When the quantity of oxygen required is such as to produce too high a temperature, it is preferred to conduct the oxidation in several stages as above described. In an example a gas containing about 3 parts methane to one of ethane yields a gas mixture containing methane 70 parts, ethane 17 parts, nitrogen 10 parts, and small quantities of carbon oxides, hydrogen and unsaturated hydrocarbons, the oxidation products containing 2 to 4 parts acetaldehyde and higher aldehydes, 60 parts methanol and 25 to 40 parts formaldehyde.

Filed: 1960-06-24
Abstract: 895,368. Drawing glass rods. AMERICAN OPTICAL CO. June 24, 1960, No. 22281/60. Class 56 [Also in Group XX] A light transfer optical device of the kind comprising a number of parallel juxtaposed rods through which light is transmitted confined therein by total internal reflection, is produced by assembling rods of glass of relatively high index of refraction, each coated with a glass of relatively low index of refraction, heating to cause the rods to soften and bond together and then drawing the assembly down to a smaller cross-section. The rods may be round, square or hexagonal in cross-section and the outer coating may be provided by dipping. A rectangular section assembly of rods may be located during heating in a cavity of corresponding shape, e.g. between two blocks, each of which is formed with a V-shaped groove. Any voids between the rods may be evacuated. Alternatively, a similar assembly 43, Fig. 8, is passed through a heater 44, and pressed together by V-section rollers 45, 46 as it passes between heaters 52, 54. The assembly is drawn out by rollers 66 after passing through a further heater 60. But using successive heaters at different temperatures a tapered section may be produced, sections of the drawn assembly may be clamped, stuck or fused together to give the necessary cross-sectional area. The drawing process may be repeated to produce finer individual rods. The drawn sections may be bent during assembly to form, for example, a device 94, Fig. 11, for transmitting an image from a cathode ray tube 96 to a screen 98. Fig. 12 shows an assembly of parallel rods for transmitting light between differently curved components of a lens system, the ends of a finished assembly are polished or immersed in oil of the same refractive index.

Title: Improvements in or relating to data recording apparatus
IPC: H04L13/08
Filed: 1965-05-27
Abstract: 1,098,431. Electric selective signalling; recording and playback. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 27, 1965 [June 25, 1964], No. 22544/65. Headings G4H and G5R. Apparatus for recording serially on a record member a train of coded signals representative of a text, includes means responsive to the recording of at least one chosen coded signal to provide in the serial record of the coded signals an interval which permits the later recording therein of a coded signal additional to the train. When an operator types out a message, the typed characters and typewriter control characters ere recorded on a selected one of two magnetic tapes. Either tape can then be used to control the typewriter, stopping after each character, word, line or after a stop code is encountered, as selected by a knob, to enable corrections to be made. The typewriter has two carriage eturn keys, one of which, when pressed, records a feed code after the carriage return code on the tape. The feed code steps the tape on playback without printing a character, and effectively provides a gap which can be used for inserting an extra character if necessary during the correction. Extra feed codes and other control codes (e.g. " switch to other tape ") can be recorded on the tape by pressing corresponding buttons (Fig. 3, not shown). A skip button enables printing of particular characters, words &c. from the tape to be avoided. Data from one tape being printed can also be transferred to the other tape concurrently. A desired block of data on a tape can be located by automatic counting of search bits previously recorded in a predetermined channel of the tape by means of a button, until a number set up on knobs is reached. Parity checking is performed. A slide holding read-record heads (96, 97, Fig. 7, not shown) for the two tapes can be moved transversely across the tapes to read a character (the signals from only one head being used) or the slide can be locked by a spring- loaded solenoid armature (100) in a position to read the search bits while the tape moves longitudinally. All bits are recorded at 45‹ to the tape length (Fig. 2, not shown). References are included to Specifications 1,098,432 and 1,098,433.

Title: Pump in which the delivery is automatically regulated in dependency on the speed, more especially for fuel injection
IPC: F02M59/00
Filed: 1959-07-01
Abstract: 921,051. Fuel injection pumps. P. E. BESSIERE. July 1, 1959 [July 2, 1958], No. 22640/59. Class 102(1). [Also in Group XXIX] A fuel injection pump comprises a piston 1, Fig. 1, actuated by liquid admitted to chamber 2a to deliver fuel from chamber 2b through an outlet 8. The actuating liquid is supplied by an accumulator 10, which is preferably fed by a gear pump 14, through a conduit 19 and conduit 20 to chamber 2a. Communication between these conduits 19, 20 is controlled by a rotary valve 15, provided with grooves 16, which is driven at a speed proportional to the engine. The valve 15 is also provided with grooves 23 which provide communication between parts of conduits 22 to allow for the suction stroke of the piston 1 which is loaded by a spring 3. During this suction stroke liquid is transferred from the chamber 2a to the chamber 2b through conduit 22, axial passage 29 in a valve member 25, a throttle formed by conical surface 24 and port 26, and conduits 27 and 9. As the speed of the engine and hence the rotary valve 15 increases above a predetermined value a groove 16 will provide communication between conduits 19, 20 before the piston 1 has completed its return stroke and thus the delivery stroke of the piston 1 and the quantity of fuel delivered is also reduced, the end of the delivery stroke being determined by the opening of a by-pass conduit 6. The throttle 24, 26 may also be varied in accordance with engine speed by the delivery of a second gear pump 31 acting on the end of the valve member 25, the delivery of this pump being returned to tank 34 by conduit 33 which is throttled by a valve 36 also adjusted by the pump delivery. Since the pressure from the accumulator 10 must be sufficient to actuate the piston 1 it is preferably increased by an intensifier. As shown in Fig. 2 the gear pump 14 feeds to an accumulator 10a and the shafts 15, 15a of the gears from rotary valves controlling the admission and exhaust of liquid to and from chambers 38a, 38b, 41a, 41b, of the intensifier. With the shafts in the position shown liquid in the accumulator 10a is fed through conduit 13, passage 46 in valve 15, conduit 44 to chamber 41a and through conduit 13, passage 47, conduit 42 to chamber 38a while chamber 38b is connected to exhaust through conduit 43, passage 50 of valve 15a and conduit 51, and chamber 41b is connected through conduits 45, 19b, groove 16b of valve 15, conduits 20b and 20 to chamber 2a to actuate the piston 1. When the shafts rotate through 90 degrees similar passages and grooves connect the chamber 41a to chamber 2a, chamber 38a to exhaust and chambers 38b, 41b to the accumulator 10a. Specification 861,754 is referred to.
