Title: Improved duplicating apparatus for use in book-keeping
IPC: B41L3/02
Filed: 1945-06-30
Abstract: 594,383. Ink-ribbon mechanism. ELBOGEN, H. H. June 30, 1945, No. 16684. [Class 100 (iv)] [Also in Group XV] In a book-keeping appliance for duplicating entries made on one sheet on to another sheet by means of an ink-ribbon, the operation of inserting a new top sheet automatically causes line-spacing of the ink-ribbon. The two sheets are retained on a board b by two separate spring-hinged clamping-bars c, d and the inkribbon u is stretched between pins t<1> on a strip-metal holder t secured to a carriage f slidable along the bar c. A pawl k carrying a pin o slidable in slots q<1> in side-plates g of the carriage f engages ratchet-teeth l on the bar c. When the bar d is lifted to replace one top sheet by another, it engages a pin h on one arm v of a lever v, m, the other arm m of which is slotted to engage the pawl-pin o. The carriage is thus caused to move a distance corresponding to a line spacing. A spring on the spindle n of the lever v, m, causes the pawl k to slip back over one tooth when the bar d is lowered. into clamping position. The distance moved can be varied by adjusting the position of the pin h on the arm v or by using a bar c with a different tooth spacing. Moreover, the frame f can be moved by hand, if desired. In a modification, a gearwheel on the carriage may engage a rack or the bar c, and be driven from a ratchet- and-pawl device on the spindle n. For obtaining a second copy, another ribbon holder is provided beneath the holder u. According to'the Provisional Specification, a two colour ribbon with a shift lever may be provided.

Title: Producing or promoting chemical reactions
IPC: B01J19/08
Filed: 1946-07-22
Abstract: <PICT:0714698/III/1> <PICT:0714698/III/2> Chemical reactions, through ionization and excitation of molecules and atoms in gaseous phase, are promoted by effecting confined flow in a tube, of reactant gas at substantially constant mass velocity, subjecting the gas in the direction of its flow to zones of decreasing intensities of a high frequency alternating electric field, the ratio of internal diameter of the tube to the internal diameter of the field creating means being no greater than 0.4, maintaining a substantially constant subatmospheric pressure of the gas and a frequency and strength of the electric field effective to produce and maintain a resistive type discharge within the gas by multiple electron-molecule collisions per cycle of the field, and causing the gas to leave the field at a low intensity zone thereof, whereby the gas molecules and atoms are subjected in succession to progressively decreasing electron velocities and after passing through a zone of optimum electron velocity are not subsequently subjected to destructive higher electron velocities.  Reactions referred to are nitrogen oxides from air, ammonia from nitrogen and hydrogen sulphur trioxide from sulphur dioxide and oxygen, methyl alcohol from carbon monoxide and hydrogen, and acetone from carbon dioxide and methane. Suitable values of variables are voltage 4,000-4,500, pressure 4.69-487 mm., and frequency 27.9- 43.2 megacycles.  The reactant gas is fed to entrance 26, Fig. 5 of tube 25 having spaced capacitive rings or maybe sleeves 27, 28 connected to power source 29 and passes out as two streams through identical fields 30, 31, where the lines show the field pattern and whose voltage gradient is a maximum in the vicinity of the entrance and decreases outwardly.  Alternatively the gases are fed to entrances 41, 42, Fig. 7, and withdrawn through 43 and the ends of the tube 40. Inductive field creating means, such as helical coil 32, grounded at the mid point whose length is preferably equal to the diameter, may be used in place of the capacitive members. Specification 700,801 is referred to.

Title: The production of tyres
IPC: B29D30/06
Filed: 1961-05-08
Abstract: 989,733. Making tyres. NATIONAL RUBBER MACHINERY CO. May 8, 1961 [May 23, 1960], No. 16719/61. Heading B5A. Nylon cord tyres hot from a cyclically operated vulcanizing press are cooled in ambient air for two cycles of the press with the cords under tension by the tyres being inflated. Figs. 1, 2, 4 show a dual post inflation device 30 attached to a press so as to receive on pairs of rollers 95 pairs of tyres T from discharge roller conveyers 25. Each tyre T is halted by a pair of stops 96 in alignment with bead rings 73, 86. Rams 61, 62 draw a bottom transverse frame member 42 upwards to lift the tyre T from the rollers 95 and to clamp it between the bead rings 73, 86 which are then locked by rotation of projections 82 by a ram 88 to provide an airtight enclosure for the T which is then inflated. A ram 52 now brings the entire mechanism comprising the bottom transverse frame member 42 and intermediate and top transverse frame members 43, 44 downwards until bead ring 74 (Fig. 1) is in the position formerly occupied by bead ring 86. In this position tyre 102, which has been cooling during the previous cycle of the tyre press, is deflated, ram 68 is actuated to raise the top transverse frame member 44 and to position conveyer rollers 100 upwardly into the position of the rollers 95 in Fig. 2 so that the cooled tyre 102 is stripped from the bead ring 74 and rolls clear of the device along the rollers 100 to be stored. Stops 96 are then repositioned for the next tyre coming from the press. Fig. 6 shows an embodiment wherein springs 133 on bead ring structures 130, 131 which are associated with bead ring structures 141, 142 allow the distances between the mating rings to increase from 1<SP>5</SP>/8 inches to 5 inches as the tyres are inflated. Bottom bead ring assemblies 187, 188 are provided with a similar floating action by a cylinder 210. In order to facilitate cooling hoods and water sprays may be provided, whilst the tyres may be rotated while being cooled. Instead of reciprocating the bead ring structures along an inclined guide they may be rotated about a central axis progressively to position each set of such structures in the proper loading and unloading position. More than two sets may be employed, depending on the length of time required for cooling with respect to the cycle time of the press.

Title: Improvements in or relating to a cable-tool drill
IPC: E21B1/02
Filed: 1951-07-13
Abstract: 702,857. Cable-tool drills. RUSTON-BUCYRUS, Ltd. July 13, 1951 [July 14, 1950], No. 16741/51. Class 85 A percussive cable-tool drill has a hollow guide, supported on the drilling mast adjacent its base, which encompasses the tool and cable and which has a shiftable longitudinal section, and link means which connect the shiftable section to the guide support and which, when the section is shifted from its normal position to open the guide, move it vertically and outwardly sideways. In the form shown, the tool guide 24 is split longitudinally into two sections 24a, 24b which are supported on guide brackets 31a, 32a and 31b, 32b by arms 27a, 28a and 27b, 28b respectively. The arms 27a, 28a are pivoted to the guide section 24a by pins 29a, 30a and to the guide support brackets 31a, 32a by pins 33a, 34a. Similarly the arms 27b, 28b are pivoted to the guide section 24b by pins 29b, 30b and to the guide support brackets 31b, 32b by pins 33b, 34b. The group of pins attaching each guide section are all horizontal and parallel but are oblique to the fore-and-aft axis of the drill rig, and each group of pins is at substantially 90 degrees to the other. Each guide section is raised vertically and, due to the obliquity of the pins, outwardly sideways by the action, via the linkwork 38, 46, 47 48, 49, of the hydraulic piston-and-cylinder assembly 36 on the lower links 28a, 28b. The assembly 36 is controlled from a valve 37 having " raise ", " lower ", hold " and " fioat positions. In the latter position the guide sections may move freely upwards if hit by the upward stroke of the drill. In another form, Fig. 6 (not shown), the pivot pins are additionally inclined to the horizontal, and in a further form the pivot pins are parallel to the fore-and-aft axis of the drill rig. An electrical or mechanical system may be substituted for the hydraulic assembly 36.

Title: Improvements in motor vehicle transmission controls
IPC: H02P9/00
Filed: 1935-06-11
Abstract: 458,088. Transmitting mechanical power. SOUSEDIK, J., Vsetin, Moravia, Czecho Slovakia. June 11, 1935, No. 16776. Convention date, Dec. 7, 1934. [Class 38 (iv)] Automatic speed control of vehicles driven by an internal-combustion engine through electrical variable speed transmission means provided with a direct mechanical drive, is characterized in that the controlling means of a servomotor which actuates the field regulator is operated by a speed-influenced device driven by the engine and is also independently operable by the accelerator or other fuel supply control, so that the field regulator is always adjusted to a position corresponding to the position of the accelerator and the speed of the engine. The electrical transmission may be that described in Specification 435,136. In the construction shown the field regulator 25 is operated by the piston 23 of a fluid pressure servomotor, the valve 18 of which is controlled by a floating lever 13 connected by link 14 to an engine-driven governor O and by a slotted link 12 to the accelerator pedal P. When the pedal P is moved from position 1 to position the throttle 1 is opened by link 7 but the slot 12<1> in link 12 allows this movement to take place without directly affecting lever 13. As the engine speed increases due to the opening of the throttle the governor O moves link 14 and valve 18 to the left, thereby admitting pressure liquid from pump 19 to the left of cylinder 21 moving piston 23 to the right and causing the regulator 25 to cut out resistance and increase the speed of the driven shaft. In the final position of the regulator the electrical transmission is cut out and a direct drive obtained. If the load increases and the engine speed falls the regulator is moved back again to control the speed of the driven shaft relatively to the engine. On further depression of the pedal P from 2 to 3 the throttle remains fully open against a stop 26, a spring 8 in link 7 being compressed, the link 12 takes up the lost motion caused by slot 12<1> and rocks the lever 13 about point 28 as a fulcrum to move valve 18 to the right and thereby insert more resistance in the field, so that the speed ratio of the transmission is increased and greater torque applied to the driven shaft. When the pedal P is released it is returned to position 1 by a spring 5, the throttle closes, the engine runs at idling speed, and the field regulator is returned to the starting position. The lever 13 bears against a stop 27 when reduction of engine speed causes the link 14 to move to the right.

Title: Ultrasonic vehicle detection system
IPC: G08G1/04
Filed: 1960-05-12
Abstract: 953,872. Acoustic energy object detection systems. GENERAL RAILWAY SIGNAL CO. May 12, 1960 [June 16, 1959], No. 16790/60. Heading H4D. Objects passing between a fixed position and a fixed surface are detected by means controlled to one condition by the reception at the fixed position of reflected sonic energy pulses originally transmitted from said position and controlled to a different condition if reflected pulses are not received during a predetermined interval after their transmission. As applied to the detection of vehicular traffic a transmit-receive electro-acoustic transducer 10, Fig. 1A (the fixed position), is driven by pulses of audiofrequency energy having a repetition period approximately equal to the " go-and-return "  time for such pulses between the transducer 10 and the roadway 11 (the fixed surface). The transmission of these pulses is controlled by a multivibrator 15 (Fig. 2) which also operates (closes) the gates 20, 24 in the receiving circuitry during the transmission of pulses so that operation of a relay 26 is prevented by the reception of pulses reflected by the roadway 11. At all other times the receiving circuitry is " open " and the reception of pulses due to reflection by passing vehicles (a threshold device 23 distinguishing between these and pulses reflected by people) is then employed to operate relay 26 which is so arranged that the continued intermittent reception of vehicle reflected pulses at a rate above a predetermined minimum causes relay 26 to remain picked-up whilst non- reception of such pulses during a predetermined interval causes it to drop away. Instead of directing the transducer beam vertically downwards it may be directed at an angle towards approaching or receding traffic or it may be directed across the roadway. In the latter case the fixed surface comprises a sheet of sound reflecting or sound absorbent material positioned in the roadway between adjacent lanes of traffic and in another application of the invention such an arrangement is utilized to detect objects moving along a conveyer belt (Fig. 1B, not shown). In a modification of the circuitry of Fig. 2, the repetition period of the multivibrator 15 is made longer than the " go-andreturn " time of the pulses between the transducer and the fixed surface and the presence of objects is then detected by the interruption in the otherwise regularly received surface reflected pulses (Figs. 5, 6A and 6B, not shown). Specification 931,125 is referred to.
