Filed: 1946-02-19
Abstract: 608,788. Dividing by fusion. DOD, C. Feb. 19, 1946, No. 5214. [Class 83 (iv)] [Also in Group XI] In an oxygen jet metalcutting apparatus a long heating jet or a series of heating jets b and a forwardly inclined cutting jet e are directed on to the work h within a distance in the line of cut of less than 1 inch. The heating jets may be 0.025 inch bore spaced 0.07 inch apart and the cutting jet may be 0.15 inch from the last heating jet and machined 5 to 45 degrees from the vertical. The base of the nozzle formation may be stepped so that the cutting jet, which may be of convergent divergent section, is nearer the work than the heating jets. Side screens may be provided for the heating jets. An additional cutting jet l, inclined transversely to the line of cut may be provided to bevel one of the cut faces. The heating and cutting jets may be formed as separate units coupled together.

Title: Improvements in methods of producing metallised capacitor tapes and capacitors produced thereby
IPC: H01G4/26
Filed: 1962-02-12
Abstract: 941,215. Capacitors. SIEMENS & HALSKE A.G. Feb. 12, 1962 [Feb. 15, 1961], No. 5278/62. Heading H1M. Relates to a method of producing metallized capacitor tapes in which a non-conductive dielectric substance 2 is deposited on a carrier body 1 and in which a metallic coating 3 is subsequently deposited on the substance in spaced strips, wherein the carrier body and the dielectric substance are cut together between the strips, as at 4-4<SP>1</SP>, into like elements so that each metallic strip covers only a part of the surface area of the substance in each element. The dielectric substance 2 in each element is then detached from its associated carrier body 1 and is folded to form two plane portions substantially parallel to each other (see Fig. 2), the relative positions of the fold 5-5<SP>1</SP> and the part covered by the metallic coating 3 being such that the metallic coating is exposed and covers at least a major part of one of the plane portions but does not cover or covers only a minor part of the other plane portion. To form a capacitor two or more such units may be placed together, as shown in Fig. 2, the areas where the coatings overlap the bent edges serving as suitable positions at which to attach leads. The invention is said to improve the dielectric breakdown strength of a capacitor assembly without substantially increasing the manufacturing costs.

In apparatus for cooling hot combustible briquettes, or similar lumps of material, the briquettes are carried on a mesh conveyer 1 through an elongated inclined chamber 3, containing a bed of sand fluidized by a cold inert gas, and are discharged over a low weir 2. Cold sand from a hopper 12 passes through the chamber 3 by gravity, in counterflow to the briquettes, the heated sand being discharged over a weir 4 into a downpipe 5, from which it is carried to a fluidized bed sand cooler 7 by the action of a cold air injector 6. Cooling in the chamber 7 is by a cold water coil 8. The cold sand leaves chamber 7 at 9 and is returned to the hopper 12 by means of an injector 10 the sand being separated from the carrier air stream by a cyclone 11. Prior to entering the cooler 7, hot sand may be passed through a precooler (Fig. 2, not shown) in which water is injected into a fluidized bed of the sand by means of a spray device.

Moulds.-Comprises improvements in moulds for moulding or casting plastic and like substances, e.g. concrete blocks &c., particularly of the type in which the mould is inverted for discharge and in which the mould is furnished with loose side and end linings. The mould 11 is furnished with loose side and end linings 13, 14 which are shouldered so that the end linings 14 retain the linings 13 within the mould. Catches 1'7 pivoted at each end of the mould are furnished with tail-pieces 19 adapted to engage over the end linings 14 as shown on the left of Fig. 2, whilst the mould is being charged, and with ears 20 adapted to engage a pallet 21, Fig. 3, when in the position shown on the right of Fig. 2, and to retain the pallet against the mould whilst it is inverted by turning the shaft 27. After inversion, the catches are turned to the position shown in Fig. 4, so as to free both the pallet and the linings, after which the mould is restored, leaving the block with the linings on the pallet; the linings are then withdrawn for re-use, and the block is removed on the pallet. The mould bottom 24, Fig. 3, is provided with grooves slidably engaging ledges 23 on the sides, and is freed from the moulded block by operating a lever 25, Fig. 2; alternatively, it may be oscillated about a pivot on a side or end, or may be reciprocated on rollers &c. supported by the sides or ends.

IPC: F16H63/30
Filed: 1927-03-01
Abstract: 275,159. Thompson, E. A. Aug. 2, 1926. [Convention date.] Operating clutches; controlling variable-speed gearing.-Dental clutch members such as 28, 29, Fig. 1, are synchronized by the prior engagement of friction clutch members 25, 25<1> by means 35, Fig. 2, having mechanical advantage. The invention is described as part of a variable-speed gear in which double clutch 29, 30 is moved to end positions for direct drive and second speed, and a gear 20 is moved into mesh for third speed and reversed drive. The constant-mesh gear 25 to be entrained is moved to the left of Fig. 1 into engagement with friction cone 25<1>, which is fast on shaft 3. This cone has a spiral groove 58, Fig. 4, the effect of which is to let oil escape and to tend to screw the clutch parts into firmer grip. Oil is pushed inwards through a channel 59 by gear teeth. One friction surface is preferably hardened steel, while the other is composed of a soft matrix in which are embedded very hard crystals such as bronze alloys. To engage the clutch, a selector bar 32 with a striker 31 for the dental clutch 29 is moved to the left of Fig. 1, that is to the right of Fig. 3. The lever 35, Fig. 2. carries a spring plunger 43, which engages a recess 49 in the bar 32 so that, as that bar is moved, the lever 35 thrusts the gear 25 into firm frictional engagement with the cone 25'. The teeth 28, 29 are synchronized. The end of the plunger 43 then passes over to an incline 51, Fig. 3, so that the bar 32 is accelerated to bring the clutch 29 into toothed engagement. In the event that the teeth 28, 29 abut, the former are tapped free from the cone and there is engagement without shock. Time for the synchronization is obtained by a dash-pot at the base of the plunger 43, Fig. 2. Splashed oil enters a channel 45. In the change-speed gear, there are two such clutches operated by levers 34, 35 controlled by the same bar 32. A bar 23 for the other speeds is selected by a ball-supported lever 24, which may be arranged to give a greater travel to either bar by means shown in Fig. 7. The levers 34, 35 are pulled together by a spring 55 which returns either after displacement against a stop 56. An arrangement is described to delay the displacement of the striker 31 behind that of the lever 35 comprising a sleeve on the bar 32 with balls and stops. In Fig. 6 is shown an arrangement to provide lost motion between the striker 31 and the dental clutch 29, 30.

A wringer 10 is mountable on a washing- machine or other apparatus in a removable and/or pivotal manner, and supporting members are provided to enable the wringer to be mounted with its driving member 31 at either side of the apparatus. Each end of the wringer has a depending leg 37 and 38 having supporting pins 24, 39 and 40, 41 respectively.

To invert the wringer it is moved slightly to the right against the action of a spring 27 and allowed to pivot about the pins 24, 41. If the handle is to be on the left-hand side, the wringer is supported by the pins 39, 40, 41, and a pivoted arm 47 on the leg 37 (see Fig. 5, not shown) spaces the leg 37 from the bracket 18 and prevents axial thrust on the handle 31 from disengaging the wringer from its supports.
