IPC: A01B3/50
Filed: 1917-05-15
Abstract: 114,516. Bell, W. T., Watson, W. H., and Jones, L. W. May 15, 1917. Ploughs.-A combined motor plough and tractor is provided with two front driving wheels and a rear driving and steering wheel. The engine A drives, through a clutch C operated by treadles D, a shaft E provided with a pinion H and driving pulley G. The pinion H, when the pulley G is not being used for driving other machinery, is ananged to mesh with a pinion J on a shaft K which drives, through change-speed and recessing gear operated by a lever S, a coun. tershaft W carrying two chain pinions X from which motion is transmitted to the front axle v and a chain wheel b on a universal joint shaft c connected by a universal joint d to the rear driving-wheel shaft e. This shaft carries a chain wheel n from which a chain wheel p, secured to the hub m of the back wheel, is driven. The hub m rotates on a wheel centre l pivoted on a central vertical pivot k passing through the fixed back axle j. The wheel centre l carries an upwardly extending arm in which the shaft e is mounted and this arm is extended and pivoted in alinement with the pivot k in a frame f extending upwardly from the main frame. The wheel centre l is adapted to be turned for steering purposes about its pivot k by an arm h secured to its upper extension and provided with teeth engaging a worm on a shaft 26 operated from the steering wheel 24. Adjusting pinions r, s are provided to tighten the chains. The front axle v is mounted in spring-cushioned axle boxes w fitted in horn brackets x which may be adjusted to tighten the driving chains. Each of the front driving wheels z is adapted to be clutched separately to the axle v through dog clutches 2 arranged to be thrown in by rotating cams operated by treadles 4, 5. A draw-bar 9 supported bv three horn plates 8 carries an adjustable spring plough hitch 10. A main drawbar 11 and an auxiliary draw-bar 12 are fitted at the rear of the machine. The ploughs 13 are lifted by means of three separate chains or wire ropes 14, 15, 16 connected to one main rope 17. The three ropes are so adjusted that the front plough is first lifted. The main rope 17 passes through a bell-crank lever 19 and is fastened to a drum 20 on the counter-shaft W. The lever 22 clutches the drum 20 to the shaft W to raise the ploughs, a clip on the main rope engaging the bellcrank lever 19 and throwing the clutch out when the ploughs have been sufficiently lifted. A ratchet and pawl device holds the ploughs at the required height. The ploughs are lowered by moving the lever 22 in the opposite direction to disengage the pawl, the clutch being slightly en. gaged at the same time to act as a brake. A band brake 27 on the front axle is operated by a hand-wheel 35. Specification 16724/15 is referred to.

Title: Voice synthesizer
IPC: G10L13/02
Filed: 1972-02-15
Abstract: 1387321 Speech synthesiser R T GAGNON 15 Feb 1972 [1 March 1971] 6966/72 Heading H4R In a speech synthesiser an 8 bit input signal is fed into a register 76, two of the digits are used to control the frequency of a voiced excitation function generator 14 while the remaining  digits are fed to a memory matrix 80 which converts the 6 bit signal into a particular combination of binary signals on its output leads. The output leads are connected to resistor adding networks 82a to 82j to provide a number of analogue control signals which control, in the synthesiser 18, the characteristics of the excitation signal, the frequency and amplitude of formants synthesised by the tunable filters 42, 44, 46, and the duration of a speech phoneme synthesised by the apparatus. The analogue control signals are generally applied to the synthesizer via low pass filters 84a to 84h, to make the transistion between phonemes smooth. As described, a resistive adder 82a controls an exponential function generator 86 to produce, when required, a step-function followed by an exponential decay which, when applied to analogue multiplier 30 connected to the noise generator 16, provides a modulation of the excitation function to generate a "plosive". A further adder 82d via a low pass filter 846 controls a chopper 92 which is fed with a signal from the voiced excitation function generator and also controls multiplier 30 to provide a pitch frequency modulation of the noise generator during production of a voiced fricative, such as "b" "z", &c. Resistive adders 82f, 82e, 82d, control the frequencies of respective filters 42, 44, and 46, via respective filters, 84f, 84e, 84d to provide formant frequency emphasis. Analogue multipliers 60, 64, and 27 provide control of the relative amplitudes of the formants and a background excitation function signal, according to the outputs of further adder networks, and an adder network 82j, via timing control 98, controls the duration of the phoneme corresponding to the input signal fed to register 76. A fixed resonant filter 69 at the output of the synthesizer provides a fourth formant corresponding to the natural resonant frequency of the nasal cavity in a speaker. Circuits are described for the various parts of the synthesizer.

Filed: 1974-02-15
Abstract: 1420568 Calcium fluoride BAYER AG 15 Feb 1974 [17 Feb 1973] 6972/74 Heading ClA CaF 2 , with a low SiO 2  content, is produced by adding aqueous H 2 SiF 6  to an aqueous suspension of ground CaCO 3  at temperature of 0 to 40 C. and adjusting the CaCO 3  to over-all water ratio so that there are at least 3 parts by weight of H 2 O present for 1 part by weight of CaCO 3 . The CaCO 3  is used in approximate stoichiometric amounts but the reaction may be carried out in stages. Thus the CaCO 3  may be reacted in a first stage with a deficit of H 2 SiF 6  and the resulting CaF 2  filtered off and treated with some of all of the H 2 SiF 6  required for complete reaction. Alternatively, as in Examples 1, 3 and 4, excess H 2 SiF 6  is first added to a suspension of ground limestone and after a period of time further ground limestone is added.

Abstract: 1,080,303. Bearings. PERMAWICK CO. Inc. Feb. 18, 1965, No.7022/65. Heading F2A. Apparatus for filling bearing cavities 78 with oil-impregnated wicking material, comprises a container 12 containing a predetermined amount of material, which container is positioned in an injection device which forces material from the container into a bearing cavity 78. A number of containers pass in sequence through the device to fill cavities in respective bearings. The device includes a passageway 28 through which passes a row of containers connected by straps, and an outlet orifice 46 extending from the passageway to a nozzle 66. When a bearing 70 is placed on nozzle 66 switch 82 is deflected and actuates pneumatic piston 44 to move rack 42 to operate wheels 34 which position a filled container adjacent the outlet 46. The rack then deflects switch 84 which actuates pneumatic pistons (56, 58, Fig. 2, not shown) to clamp members (48, 50) around the cylinder. These members then deflect switches (86, 88) which actuate cylinder 62 which forces piston 60 through wall 18 of the container to push its contents through nozzle 66 into the cavity. The plunger operates a switch 90 which retracts the pneumatic pistons in turn. The process is then repeated. The cavity comprises an annular recess in bearing body 74 which is closed by a sleeve 72 having a window 80 through which the material is introduced.

Title: Improvements in Connecting Rods for Internal Combustion Engines.
Inventor: BARBAROU MARIUS JEAN BAPTISTE
IPC: F16H21/34
Filed: 1918-04-30
Abstract: 116,086. Barbarou, M. J. B. May 9, 1917, [Convention date], Connecting-rods.-In a V-type internal-combustion engine, the big-end of the main connecting- rod A is formed in halves secured together by bolts and is mounted directly on the crank-pin, and the auxiliary connecting-rods E are formed with forked feet M which bear on the main connecting- rod end through the intermediary of loose split liners D. In order to secure longer bearing surfaces for the feet M the ends of the feet may be inclined to the axis of the crank pin. The feet M are retained in position by a split ring F at each side of the main connecting-rod, the halves of each ring F being secured together by a bolt G and a screw bolt H. The two rings F are connected by bolts K and a bolt I, the latter passing through a projection on the end of the connecting- rod A.

Title: Improvements in or relating to apparatus for controlling the supply to electrical load circuits
IPC: B23K11/24
Filed: 1939-03-06
Abstract: 526,035. Control systems for consumption apparatus. IGRANIC ELECTRIC CO., Ltd. March 6, 1939, No. 7287. Convention date, March 26, 1938. [Class 38 (iv)] Switching control.-For the cyclic control of the A.C. supply to a stitch welding machine, the power circuit is opened and closed by an electromagnetically-operated and electromagnetically-tripped switch the operating and tripping circuits of which are under the control of electronic discharge devices controlled in relation to the cycle of the A.C. source and serving to determine, adjustably, the intervals between closing and opening and opening and closing of the power circuit. In the Figure, the supply to a welding transformer 29 is controlled by contacts 1a of a switch 1 which is closed by a coil 1d, maintained crosed by a latch 1e, and opened by a coil 1f. Before a switch 11 is closed to start the cycle a gaseous electronic valve 7 is conducting, its grid and cathode being at the same potential, and current passes from direct-current mains through a resistance 12 and a potentiometer 13. Contacts 1c prevent the conductivity of a valve 5. When switch 11 is closed, a valve 6 is rendered conductive, while the conductivity of valve 7 ceases, firstly, because of the momentary drop in anode potential caused by the presence of a condenser 16 and, secondly, because of the negative bias produced by the discharge of a condenser 18 through a resistance 15. The conductivity of valve 6 causes a volt-drop across a potentiometer 10 which partly overcomes a negative bias 26 on a valve 4 so that an alternating potential of variable phase, supplied through a transformer 25, can render valve 4 conductive, at a predetermined point in the voltage cycle, to energize coil Id and close switch 1. When switch 1 has closed, contacts 1b prevent further conductivity of valve 4. Valve 7 becomes conducting again after a period determined by the discharge time of condenser 18 through resistance 15 and, when it does so, condenser 16 causes valve 6 to become non-conducting for a time determined by the discharge of condenser 17 through resistance 14. Since contacts 1c are now closed, the volt-drop across potentiometer 13 caused by the conductivity of valve 7 can render valve 5 conductive, after the manner of valve 4, so that coil 1f is energized to open switch 1. When condenser 17 has discharged the cycle repeats. The resistancecapacity timing circuits are adjustable to vary the open and closed periods of switch 1 while, by adjustment of phase shifters 27 and 28, the switching may be arranged to take place at the zero point in the voltage cycle.

Title: Improvements in means for polishing or grinding blades or the like
IPC: B24B19/00
Filed: 1949-03-18
Abstract: 672,903. Grinding & polishing. SZUTOWICZ, S. Feb. 27, 1950 [March 18, 1949; July 20, 1949], Nos. 7400/49 and 19059/49. Class 60. Means for grinding or polishing the blades of agricultural implements &c. comprises means for reciprocating the blade while it is supported on a powerdriven grinding wheel 1 and pressed against the latter by a non-grinding roller 14. The blade 8 is carried from a pivoted arm 3 adapted to be oscillated by a connecting rod 4 attached to one of a number of eccentric pins 5 on a disc 6 which is driven by a belt 7 from a shaft 2. The blade is gripped between two pivoted jaws 10 on a holder 9 under the control of a lever 11, and the holder is rotatablyadjustable in a bracket 12 which is pivoted to a member 13 arranged for rotation about the axis of the arm 3; The roller 14 is rotatably mounted in a bracket 15 which is pivoted on the lower end of a slide 17 movable vertically in a block 18 under the action of an hydraulic cylinder 20 controlled by a foot-lever. Lugs 21, Fig. 2, project from opposite sides of the slide through slots in the block and cooperate with adjustable springs 22 engaging the upper face of the bracket 15. The plunger of a second hydraulic cylinder 23, which is also controlled by the foot lever, is connected to one end of a brake band 24 passing around a drum 25 on the shaft of the roller 14. The application of the brake prevents the blade moving forward too quickly, particularly should it be fed by hand. When the roller 14 is lowered, one of the lugs 21 acts through a pivoted lever 30 and connecting rod 29 to cause a roller 27 to tension the belt 7 and thereby cause the blade to be oscillated. The first Provisional Specification describes also a construction in which the blade is held in a holder at the lower end of a pivoted arm which can be swung by hand so as to reciprocate the blade across a grinding wheel mounted below the arm. The second Provisional Specification describes also an arrangement wherein the blade is reciprocated across the grinding wheel by a driving roller, and a spring-pressed roller urges the blade into contact both with the grinding wheel and driving roller.

Flanging.-Apparatus for making nipples or branch openings in a tube of large diameter including a punch situated inside the tube is characterized in that the mechanism operating the punch and the punch are supported inside the tube by a cradle having fixed and movable shoes which are clamped against the inner surface of the tube and brace the tube. The tube a is supported at its ends and the apparatus is movable along the whole length of the tube to any desired point. Alternatively, the apparatus may be stationary and the tube moved longitudinally. A punch b situated inside the tube is carried by a double-acting hydraulic piston d housed in a block e disposed in a cradle f supported in the tube by a shoe h. Extensions f<SP>1</SP> and f2 on the cradle carry adjustable guide shoes i<SP>1</SP> and i<SP>2</SP> for clamping the cradle in the tube. The guide shoes may be adjusted by remote control means operating screws j<SP>1</SP> and j<SP>2</SP>. An external die c slides on vertical guides land is operated by two double-acting pistons m<SP>1</SP> and m<SP>2</SP> connected to the die and a fixed point p<SP>1</SP> and p<SP>2</SP> by connecting-rods n<SP>1</SP>, o<SP>1</SP> and n2, o<SP>2</SP> respectively. Supplementary connecting-rods q<SP>1</SP> and q2 ensure symmetry of movement of the pistons which may also be co-related with the punch piston b. The die and its operating means is supported by a frame t which rests on a yoke u embracing the lower half of the tube, said yoke and frame being assembled by a key device v (Fig. 2). In order to produce a branch opening in the tube a small hole z of approximately 1 cm is drilled in the tube and the punch is clamped in the tube opposite to the hole. The region around the hole is heated and the die is brought into position by movement of the yoke and frame support w along rails y. The punch is then operated to produce the nipple. When a series of apertures are to be provided along a generatrix of the tube the opposite side of the tube is heated to equalize the tube expansion. Detachable linings may be fitted in the yoke u to adapt the yoke for receiving various sizes of tubes. Specification 754,431 is referred to.
