Title: Bank of capacitors for voltage control on windings of transformers and chockes
IPC: H01F27/34
Filed: 1977-10-04
Abstract: The capacitor battery (54) controls the voltage of the transformer winding (55) or inductor winding (56) in a transformer or in an inductor. An individual capacitor is allocated to each winding section to be controlled. The capacitor battery (54) is constructed from disc coils which are open at one end (that is to say without any electrical connection), are wound in a plurality of layers, are magnetically decoupled from the winding (55, 56) and are assembled to form a special structural unit. All the individual capacitors allocated to the same winding or to the same winding branch of a winding are electrically connected in series. Seen in cross-section through the capacitor battery (54) and the transformer or inductor, the boundary line of the cross-section of the capacitor battery runs in the adjacent region of components of the transformer or of the inductor parallel to the cross-sectional boundary line of these components. At the same time, the corners and points which exist in the cross-section of the capacitor battery can be rounded off. As a result of the arrangement, capacitor batteries having very large longitudinal capacities for the windings can be accommodated within the tank without increasing its size. <IMAGE>

Title: Drilling apparatus
IPC: B23B41/08
Filed: 1966-09-15
Abstract: 1,149,649. Drilling pipes under pressure. T. D. WILLIAMSON Inc. 15 Sept., 1966 [16 June, 1966], No. 41247/66. Heading B3C. Apparatus for drilling a pipe containing fluid comprises a housing 10, a boring bar 11, and a lead screw 21. A nut 13 is secured to the top of the boring bar, co-operates with the lead screw, and is slidable in the non-circular bore of a tube 12. The latter is rotated by a worm and wheel drive 15, the worm of which can be driven at one end by a motor, or at the other end by a crank, a flywheel 20 being provided at one end. A slipping drive is provided between the tube 12 and the lead screw 21, and comprises a spider 22 keyed to the lead screw, and a thrust bearing 24 supported on the upper end 25 of tube 12, this end also being connected to a shoulder 27 on lead screw 21 via a ball bearing 26. A nut 28 is provided so as to adjust the degree of friction between the tube and lead screw. A friction holding connection between housing 10 and the tube 12 is provided, and comprises a spring-urged race 29 non-rotatably, but slidably, connected to housing 10 by a pin-andslot 32, 33, which frictionally engages balls 30 carried by spider 22 and supported in a race 31. In operation, nut 28 is tightened so that the lead screw, and tube 12 rotate together. Cap 37 is screwed on to the housing until the holding friction is enough to prevent rotation of the lead screw when the boring bar is rotated, so that the latter is fed at a high rate. When the tool encounters the work, the upward reaction of the boring bar, will increase the friction between nut 13 and lead screw 21, tending to cause the latter to turn and reduce the feed rate. The feed rate is therefore greater when the resistance to cutting is least, and slows down when the resistance increases. A window 41 in the housing allows the operator to see a scale on the boring bar so that he can read off the depth of cut.

Abstract: 1,082,678. Knitting. HANES CORPORATION. Oct. 12, 1964 [Feb. 19, 1964], No. 41472/64. Heading D1C. In a circular knitting machine, needle selection is made during reciprocatory knitting so that tuck loops and/or floats may be incorporated in the fabric in areas such as the heel or toe. During the first clockwise rotation of the needle cylinder the needles are lowered by stitch cam 34, and then raised to tuck level by cam 40. The pattern jacks 14 are then presented to pivoted selecting fingers 54, 48-51. Finger 54 pivots all the jacks and the remaining fingers, pivoted selectively by a cam drum Fig. 3 (not shown), push selected jacks clear into the path of the clearing cam 44. The unselected needles N" remain at tuck level. During the counterclockwise rotation, Fig. 2 (not shown), cam 34 is retracted and all the needles are lowered by stitch cam 30, and then raised to tuck level by cam 38. Floats may be produced by arranging that needles N" do not engage the yarn. The cleaning cam and selecting fingers may be duplicated at the opposite side of the stitch cams, which are both retractable, to produce tucks during each revolution.

Abstract: 1446475 Regulating air/fuel ratio ROBERT BOSCH GmbH 6 Sept 1973 [7 Sept 1972]  41952/73 Heading F1B A fuel metering system for I.C. engines with mixture compression and spark ignition comprising an air-flow measuring element 2 and an arbitrarily operable throttle valve 3 arranged in series within an air intake manifold 1, the measuring element being arranged to control a fuel metering valve 7 so that the quantity of fuel metered is proportional to the quantity of air passing the measuring element, the proportionality being variable by controlling a valve 17 arranged in a by-pass 16 around the measuring element, the valve being controlled in dependence on the pressure prevailing in the intake manifold in the region of the throttle valve. Valve 17 comprises a valve-member 19 which co-operates with a seat 22 and which is mounted on a diaphragm 20 and biased to the closed position by spring 21. The chamber on one side of the diaphragm is connected to the inlet manifold at a point 25 which is upstream of throttle valve 3 when the valve is in its closed position, but which is on the downstream side of valve 3 when the valve has begun to move towards its open position. When the manifold pressure is high i.e. at full load, the by-pass is closed so that the engine receives a rich mixture. The by-pass is also closed at idling and at starting. A restrictor is disposed at the mouth of the control line 23 so that when the throttle is opened suddenly, the valve opens slowly and a rich mixture is provided during acceleration. In a first modification the by-pass opens into the intake manifold close to and upstream of the control line so that the by-pass line itself is influenced by the throttle valve. In a second modification a shutter, mounted on the throttle valve spindle, progressively uncovers the by-pass mouth as the throttle valve is opened. In a third modification the valve 17 includes two diaphragm valves in parallel and having respective control lines which open into the inlet manifold at two points one upstream of the other, but both within the range of influence of the throttle valve.

Title: Process for the manufacture of formaldehyde
IPC: C07C45/78
Filed: 1959-12-21
Abstract: Formaldehyde, substantially free from compounds containing hydroxyl groups, is obtained by the thermal decomposition of semiformals, the compounds containing hydroxyl groups, mainly alcohols, liberated by the decomposition of the semiformals, being extracted from the vapour mixture consisting of formaldehyde and hydroxyl-containing compounds by means of an auxiliary liquid consisting of one or more aliphatic, cycloaliphatic or alkyl-substituted cycloaliphatic hydrocarbons having a boiling point within the range 80-180 DEG C. which is present at the head of the reflux column in which the vapour mixture is obtained and which has a boiling-point lower than the boiling-point of the hydroxyl-containing compound.  The auxiliary liquid is a good solvent for the alcohol to be separated and a very poor solvent for the monomeric formaldehyde and also is inert towards formaldehyde.  Suitable semiformals for use as starting materials are those of mono- or polyhydric alcohols, e.g., n-pentanol, octanols, butane-diol-1,4, pentaerythritol, cyclohexanol or methylcyclohexanols.  Suitable auxiliary liquids are, for example, decanes, nonanes, octanes, heptanes, cyclohexane, methylcyclohexanes and suitable gasoline fractions.  These auxiliary liquids may be purified before use, if required, by distillation and treatment with an absorbing agent.  The pure formaldehyde is obtained at the head of the reflux column and the hydroxyl-compounds and auxiliary liquid may be removed from the bottom.
