Abstract: 415,988. Sewing - machines. FAIRWEATHER, W. C., 65, Chancery Lane, London.-(Singer Manufacturing Co. ; Elizabeth, New Jersey, U.S.A.) Nov. 21, 1933, No. 14109/34. Divided on 416,619. [Class 112.] The invention consists in improvements in vibratory needle stitching-machines with a reversible and adjustable feed mechanism. The feed regulating and reversing mechanism is described in Specification 415,987. The needlevibrating mechanism is described in Specification 416,619. Co-operating with the needle 20 is a loop-taker 69 which receives the bobbin case 70. To accommodate co-operation with the needle 20 in different paths of the latter, the loop-taker is rotatable in a vertical plane parallel to the plane of lateral vibration of the needle. A spiral driven gear 75 carried by the loop-taker shaft engages a spiral driving gear 76 carried by an end of horizontal loop-taker actuating shaft 77 disposed below and transversely of the loop-taker shaft 69. At its other end, the shaft 77 carries a belt pulley for connection by a belt to the main shaft driving pulley.

Abstract: 1,214,081. Fluid oscillators. VSESOJUZNY NAUCHNO-ISSLEDOVATELSKY INSTITUT MEDITSINSKOGO PRIBOROSTROENIA. March 27, 1968 [March 27, 1967], No.14822/68. Heading G3H [Also in Divisions A5 and F1]. An artificial respiration apparatus comprises a fluid-switch element provided with a supply channel 4 communicating with the outlet of an injector 1, a first straight discharge passageway 5 adapted to communicate with the patient's lungs, a second discharge passageway 6 sloping relative to the first passageway, and a main control channel 7 which communicates with the straight discharge passageway, via a negative feedback channel (9), and is said to be characterized in that the fluidswitch element also incorporates a positive feedback channel (11) connecting the sloping discharge passageway 6 with an auxiliary control channel 8 located between the supply channel 4 and the main control channel 7. As shown, the injector 1 supplies an oxygen and air mixture through the channel 4, passageway 5, and a non-return valve 19 for inhalation by the patient or, during exhalation (through an outlet valve 20, 21, 22) the gas mixture from the injector passes into the passageway 6 and also out through an orifice 12 to atmosphere. The passageway 6 communicates via an adjustable throttle 15 with a variable volume chamber 14 (e.g. a bellows) able to expand and, with a movable wall 16, close the orifice 12. The changeover from inhalation to exhalation is caused by the rising pressure in the lungs and in the passageway 5 acting through the main control channel 7 to direct the gas mixture to the passageway 6, the positive feedback channel (11) then maintaining gas flow to this passageway. The changeover from exhalation to inhalation is caused either by the patient attempting to inspire, or, after a time period determined by the throttle 15, by the chamber 14 expanding to close the orifice 12 so that the pressure in the control chamber (13) rises. The fluid-switch 2 is said to be formed in a plate of an organic glass material.

Abstract: 956,731. Centrifugal pumps and compressors. DE LAVAL STEAM TURBINE CO. April 17, 1962 [Aug. 11, 1961], No. 14918/62. Heading F1C. In a multistage centrifugal pump, compressor, or the like comprising a housing containing a casing formed by a number of annular sections assembled in stacked relationship, successive stage impeller means rotating within the casing and means for bleeding fluid from an intermediate stage of the pump, compressor, or the like, the bleed means comprises at least one axially directed passage in the casing formed by intercommunicating passages in adjoining sections thereof, one of the annular sections having a radially directed passage therein connecting the first-mentioned passage with the interior of the casing, and a passage in the housing communicating with the first-mentioned passage and leading to the outside of the housing. In the centrifugal pump shown, an outer steel casing 2 contains an inner casing formed by joining concentric annular interstage portions, such as 12 and 14, and an end portion 10 by tie rods 15 (see Specification 956,732) which are anchored at their ends by shoulders engaging a flange 17 and are installed in a heated condition. The liquid is supplied through inlet 16, volute 18 and guide vanes 19 to the first stage impeller 6, from where it flows through diffuser 20 to the remaining stages. Some of the liquid leaves the second stage through a group of six by-pass ports 32, arranged approximately opposite the cross-over passage of the second-stage diffuser 24, and thence passes through six passages 30 in portion 12, six aligned passages 36 in portion 10 and three passages 46 in the outer casing 2. Circumferential channels 34, 38, 40, 44 interconnect the passages. The passages 46 discharge into a chamber 48 which is connected through welded connection 50 to auxiliary equipment or the like. The channel 44 and holes 47, aligned with the passages 46, are provided in an annular stainless steel insert 42 welded to the casing 2. Portion 10 is pulled against the insert 42 by bolts (not shown) anchored in the casing 2. Two connections 50 spaced approximately 180 degrees apart, each associated with a separate cross-over passage in the same diffuser, may be provided to feed separate units, or they may be connected 'externally to combine their output. A number of separate connections may be provided which are circumferentially spaced and each associated with a different stage of the pump, thereby providing a selection of pressures. The interstage portions 12, 14 are machined from duplicated stock parts, and the diffusers 20, 24 may be similarly constructed.

The ends of the shell may be socketed at 2 to form seats for axial flanges 8 on the walls 3, and the latter are provided with circumferential flanges 9 to abut against the shell as shown. The holes 12 are preferably bored to a diameter intermediate the body and external diameters of the screws 10.

Title: Improvements in or relating to tools for the production of brushes and brooms
IPC: A46D3/04

Abstract: 887,489. Making brushes and brooms. LOCHER, L. May 9, 1958 [Nov. 11, 1957; Nov. 14, 1957], No. 14933/58. Class 87(2). A mould plate 11 carrying depressions 12 for the moulding of bristle bundle heads has directly above it a bristle apportioning plate 8 which possesses openings 9 corresponding in number and diameter to the bundles and coinciding with the depressions 12, and a bristle container 3 with a floor 5 which may be opened so as to drop the bristles 4 into the depressions which are first filled with moulding resin, e.g. phenol or polyester resin. Between the container 3 and floor 5 is a bristle directer 2 shaped according to the outlines of the apportioning plate 8. When bundle heads with diameters greater than those of the bundles are required, the mould plate 11 is constructed in two parts which meet in a horizontal plane bisecting the mould cavities. The mould and apportioning plates and the bristle container and directer are made from transparent elastic and non-elastic synthetic plastic materials respectively. If desired, the mould plate may be constructed as the brush body, the bundle heads being moulded so as to be exchangeably connected in shape-locking fashion within it. In one modification, a single tool plate is used which serves both for the apportionment of the bristles and for the moulding of the bundle heads. The projections 31 of this single tool plate, Fig. 11, may be undercut at the bottom to allow room for plastic jackets 41 which are provided with projections 42 for connection with handles 43 when a plurality of brushes having plastic jackets are required. In further modifications, the moulding plate may be provided with core pieces for the formation of cavities between the bristles and a multi-part pre-apportioner may be arranged over the apportioning and mould plates, the different parts of which are usable separately from one another so that it is possible to secure bristles of different material in the same brush body. The walls of the pre-apportioner may be adjustable in their inclination to each other. For the production of any desired arrangement of bristle bundles, an interchangeable intermediate distributer is inserted between the bristle holder and the mould plate and is provided with bores distributed according to the desired bundle arrangement, being shut off from the bristle holder and base plate by slidable intermediate floors.
