Title: Improvements in and relating to the spraying of paint and the like
IPC: B05B15/00
Filed: 1955-12-30
Abstract: <PICT:0793275/III/1> <PICT:0793275/III/2> In a method of operating paint-stirring apparatus compressed air is fed from a pressure reservoir 17 to a compressed air turbine 24 to drive the paint-stirring apparatus before the air is conveyed to one or more spray guns 23.  The turbine which is mounted on the top of a paint container 19 has a rotary impeller 5 connected through suitable toothed gearing to a stirring shaft carrying a vane 27.  Compressed air passes through a restricted nozzle inlet 11 of the turbine on to the curved surface 13 of a blade of the impeller and then passes through a wide outlet 12 connected to the spray guns and separated by the pitch of a blade from the inlet. The turbine casing 1 is enclosed by upper and lower bearing covers.  Paint is supplied to the paint spray guns from the container 19 by compressed air which passes through a pressure-reducing valve 20.

Abstract: 833,278. Magnetic recording and reproducing apparatus. ELECTRIC & MUSICAL INDUSTRIES Ltd. Dec. 3, 1958 [Dec. 4, 1.957], No. 37724/57. Class 40 (2). Apparatus for recording on and reproducing from a tape-like medium in the form of parallel tracks comprises a rotatable carrier supporting a plurality of recording or reproducing devices describing the same arcuate path, and means for causing said medium to be moved lengthwise and in transducing proximity with said devices along a path oblique to the axis of their orbit of rotation and flexed around a portion only of said orbit whereby each device in turn can be brought into transducing relationship with successive portions of said medium. In the embodiment described, magnetic heads 2 are mounted on a disc rotating between cylindrical guide members 4 into oblique contact with which a record tape is held by guides 8. The guide members may be provided with guide ribs 13. Signals recorded on the tape may be recorded in the form of a modulated carrier to prevent cross-talk between tracks, preferably frequency or pulse modulated. Correct registration during reproduction may be effected by recording separate synchronizing signals which may be used to control a synchronous motor or a phase-locked servo drive.

Abstract: 878,314. Disc brakes. DUNLOP RUBBER CO. Ltd. Dec. 5, 1957 [Dec. 5, 1956], No. 37924/57. Divided out of 878,313. Class 103 (1). A disc brake comprises non-rotatable pressure plates 7, 8 having a pad of friction material 26, located one on each side of a disc 1, and a rotatable member 31 to move at least one plate toward the disc and effect engagement between the pads and disc, the member 31 being rotated by a rack and pinion mechanism 35, 36. A fixed housing 2, having an annular base 3 and an axial wall 4, covers part of the periphery and one side of a disc 1, the housing being cut away at 5 and having a cooling air duct formed diametrically opposite to cut-out 5. Pressure plates 7, 8 of ring-sector shape, are pivotally connected to brackets 14 fixed to a flat portion 12 of wall 4. The pads 26 of wedge-shape cross-section are fixed to backing plates 27 having flanges 28 dotted at 29 to pressure plates 7, 8, and are prevented from endwise movement by webs 30 formed on the plates 7, 8. The applying means comprises a rod 31 having a coarse right and a fine left-handed threaded ends 32, 33 engaging threaded bushes 46, 47 respectively, the bush 46 being rotatable in a recess 44 in plate 8 and bush 47, having a flange 47a, being rotatable in a bush 45 fixed in a recess 43 in plate 7 by a peg, not shown. The rack 36 is formed as part of a piston 37 slidable in cylinder 38 secured to pressure plate 7 and rotates pinion 35 and rod 31 either due to fluid pressure in chamber 53 or by a cable 56 attached to the rack by a U-member 54 and ferrule 57, the casing 58 of the cable being fixed to a boss 59 on plate 7; a double volute spring 60 returns the piston to the release position defined by the end of U-member 54 contacting housing 39. On brake application, the rod 31 rotates relative to bush 46 which is in light frictional engagement with recess 44 until a spring clip 48 held in a recess in end 32 engages the bush 46 which then rotates with rod, 31; as the threaded end 32 is moved into bush 46 the bush 47 is moved into bush 45 to bring its flange 47a into contact with bush 45; this initial movement causes the coarse thread 32 to rapidly move the plates 7, 8 together to take up brake clearance, i.e. the clearance 50 between clip 48 and bush 46, a second clip 49 being secured to the outer end of threaded end 32. The bush 47 is now held against rotation by friction between its flange 47a and bush 45, further rotation of rod 31 causes the finer threads 33 to move into bush 47 to apply the brakes. In an embodiment in Fig. 3, not shown, the housing covers less of the disc and is formed with U-shaped ends straddling the disc and having bosses carrying spherical headed bolts which seat in recesses in bosses at the ends of a reinforcing V-shaped rib on the pressure plates, the backing plates carrying the friction pads being attached to the pressure plates by spring clips integral with the backing plate. Specifications 709,305, 712,534, 712,537, 747,974, 755,356, and 813,316 also are referred to.

Abstract: 1,170,846. Seaming non-metallic sheet material. TABAKUND INDUSTRIEMASCHINEN DRESDEN VEB. 17 Aug., 1967, No. 37925/67. Heading B5K. [Also in Divisions B8 and F2] In a packaging machine for the continuous production of tubular bags, apparatus is provided for driving the transverse sealing jaws and permitting adjustment of the path of the jaws to allow for the bag-length and the speed of the packaging tube through the machine. Uniform rotary movement is transmitted from a driving shaft 19 to a sprocket mounted on the shaft 14 of a slot-and-crank 13. The rotation is converted into rotary movement of a driven crank 3 by a slide block, the rotation of the crank 3 and a spur-gear 9 connected to it on crank-shaft 5 being non-uniform due to the displacement of the centre of rotation of the slot-and-crank 13 relative to the centre-of-rotation of the crank 3. The shaft 14 of the slot-and-crank 13 is mounted in a displaceable plate 15 so that the degree of non-uniformity of the motion transmitted to the crank 3 is continuously variable. The spur gear 9 meshes with a similar gear 10 connected to a further driving crank 4, and the cranks 3 and 4 control jaw supports which extend parallel to each other and the ends of which move on slide blocks in guides. The sealing jaws (not shown) are resiliently mounted in the jaw supports. An adjusting shaft, actuating a spindle, allows the height of the sealing jaws to be adjusted by moving a plate on which the cranks 3, 4 are mounted. The apparatus described is provided symmetrically on each side of the packing tube which moves through the apparatus in a direction from left to right as shown in Fig. 2.

Abstract: 1526196 Measuring capacitance PLESSEY CO Ltd 24 Nov 1975 [3 Sept 1974] 38343/74 Heading G1U In a method of aligning the sections of a multisection variable capacitor to bring the capacitances of all the sections substantially to equality, the sections of the capacitor are automatically sequentially monitored and values related to their capacitances are displayed. As described an A.C. current, from a source 7, Fig. 1, is applied, via a reference capacitor CR, to an amplifier 10 in opposition to a current from one of the sections 1 of the capacitor under test. The difference current is then phase-conscious rectified 12 to provide a voltage V o  indicative of the value of the section 1 under examination. This process is repeated by the cyclic and sequential closure of contacts 4, so that a series of voltages V o  appear corresponding to the capacitances of the successive sections 1. These voltages are displayed on a c.r.t., each as a short horizontal line (the c.r.t. x-drive being synchronized with the sequential closure of contacts 4) so that if all the sections have the same capacitance the succession of short horizontal lines forms a straight line across the c.r.t. Since the absolute values of the capacitances of the sections are not required, and to keep the display at a convenient place on the c.r.t., the effective size of the reference capacitor CR is varied by varying the gain of an amplifier 8, by a long time constant integrator 17, to maintain the average voltage V o  constant.
