Title: Automatic turret lathe
IPC: B23B9/12
Filed: 1971-04-19
Abstract: 1337179 Turret lathes Y KITANO 19 April 1971 [19 March 1970] 24132/71 Headings B3T and B3B An automatic turret lathe comprises a headstock which incorporates a rotary indexable turn-table which carries two or more rotary work-holders which are moved sequentially into a work-station with the indexing of the turntable. To effect indexing of the turn-table the table is axially displaceable along its indexing axis which disengages the drive to the workholder in the work-station to permit its indexing movement to bring the next work-holder with its workpiece into the work-station. The embodiment shown in Figs. 1 and 2 is a vertical lathe with the headstock 1 supporting a turntable 4 carrying face-plates 6a and 6b. The turntable is mounted on a main shaft 3 which incorporates fluid operated piston-and-cylinder means 7, 8 to effect axial displacement which disengages toothed coupling members 5a, 5b and engages coupling members 11a, 11b associated with the main shaft 3 and disengages coupling members 45a, 51, between the face-plate 6a in the work-station and the drive-shafts 62, 54. The indexing of the turn-table is effected by a fluid actuated rack 15 which engages a gear 12a on a sleeve 12 attached to the cylinder 7. At the completion of the indexing movement the piston-and-cylinder unit 7, 8 is actuated in the opposite direction to lower the turn-table 4 and engage coupling 5 and disengage coupling 11, which accurately locates the turn-table in its new indexed position. Prior to indexing the turn-table a clamping member 63 engaging the shoulder 64 of the table, is released by actuation of piston-and-cylinder unit 69, 69a which is again actuated at the completion of the indexing movement to clamp the turn-table to the headstock. The sequence of operation effecting the indexing and clamping movements is controlled automatically. A fluid-actuated tool turret 70 and a cross-slide 71 are mounted on the machine frame for operation on a workpiece in the workstation. Although two work-holders 6a and 6b are shown in the embodiment, more than two may be incorporated on the turn-table and the angular indexing movement is controlled accordingly by a trip member actuating a micro switch. The embodiment shown in Figs. 8 and 9 is a horizontal turret lathe, the headstock 101 carrying an indexable turn-table with four chucks 106a-106d, the actuation of which is similar to that of the vertical lathe described in Fig. 1. In both embodiments the drive for the indexing movements and for rotating the work-holders in the work-station is from a main drive motor by way of gearing. In the lathe shown in Fig. 8 two of the four turrets are located in work-stations at the same time and are operated on by tool turrets 85, 86 and crossslides 171, respectively. The stations occupied by the remaining work-holders permit the loading and/or unloading of workpieces before and after machining operations have been carried out at the work-stations.

Title: Improvements in jacketing internal combustion engines
IPC: F02F1/16
Filed: 1924-10-13
Abstract: 245,832. Mauss, W. Oct. 13, 1924. Cylinders, cooling; systems of working. - In order to make the cylinder liner as thin as possible the liquid in the cooling-jacket is maintained at the same pressure as the working- fluid in the cylinder. The liner 7 is housed in an annular groove 10 in the cover, and communication between the combustion space 9 and the jacket 8 is by a number of pairs of grooves 12. Cooling-water is circulated by a pump 16 through a cooler 15. A variable-speed make-up pump 18, which makes its feeding stroke when the cylinder pressure is high, compensates for leakage and for steam formed during the working stroke of the piston, which steam assists this stroke; a cock 17 allows air and surplus water to escape. The circulating pump and the cooler 15 may be omitted and the pump 18 accelerated or enlarged, the cooling effect then being dependent on the steam formed. The pump 18 may be replaced by a high level water tank, which supplies the jacket through a non-return valve. In place of direct communication between the combustion space and the jacket a floating piston may be interposed; this piston has slots which still allow communication if the water-level is not maintained; an indicator is attached to the piston. The liner 7 is made thicker at the part not subjected to internal pressure.

Title: An improved toy aeroplane
IPC: A63H27/04
Filed: 1953-09-04
Abstract: 742,620. Mechanical toy aeroplanes. ERHARD, K., and JACOBOWITZ, M. Sept. 4, 1953 [Sept. 20, 1952; March 5, 1953], No. 24535/53. Class 132(3) A toy aeroplane which may travel on a surface or be suspended to simulate flight has a spring mechanism which drives at least one propeller and one undercarriage wheel, provision also being made for extending and retracting the undercarriage by means of the spring mechanism. When the toy is not suspended, Fig. 4, the propellers are driven by the main gear wheel 108 via gears 118, 118a, 120 and shafts 121, and, drive to undercarriage wheel 111 is effected through gearing 119, 110 and shaft 112. On suspending the toy by means of a plate 136, a U-shaped member 135 pivoted at 133 moves so at to cause a gear wheel 123 to be raised into engagement with a drive pinion 106. and an arm 132 on member 135 releases a slide 127.

Patent GB-897641-A (GB)
Title: Improvements in or relating to the colouring of textured glass fibre fabrics containing effect and non-effect yarns
IPC: C03C25/10
Filed: 1959-07-17
Abstract: Glass fibre fabrics containing effect yarns (e.g. ratine, slub or floated yarns) and non-effect yarns are padded with a bath containing a binding agent and a normally negatively charged pigment, the bath having been so-modified to increase the negative charge on the pigment particles or to change this charge to a positive charge, whereby the pigment is deposited, respectively, only on the non-effect yarns or only on the effect yarns.  The dispersion may also contain softeners and dulling or antislipping agents such as colloidal silica or titanium dioxide.  The negative charge or the pigment particles is increased by adding hydroxyl ions (in the form of ammonium hydroxide) to the dispersion. Reversal of the charge on the pigment particles is effected by the addition of trivalent metal ions (e.g. in the form of basic aluminium acetate) to the dispersion or, when the dispersion also contains colloidal silica, by the addition of divalent ions (e.g. in the form of magnesium sulphate) to the dispersion or by acidifying the dispersion.  When the binding agent, e.g. polyvinyl alcohol, is water-soluble, treatment with an insolubilising agent, such as stearato chromic chloride, is effected during or after colouring.  Yarns in the fabric which are initially uncoloured may be selectively or non selectively coloured by a subsequent treatment.  Two pigments, one selective to the effect yarns and the other selective to the non-effect yarns may be applied from the same bath, but in this case the appropriate charge is established on each pigment in a separate bath and the pH so adjusted that, on mixing the two baths, the charge on each pigment is not disturbed, the pH of the mixed bath being above 7.  Examples are given.

Title: Method of charging storage battery in power supply system having another battery of larger capacity
IPC: H02J7/00
Filed: 1975-06-10
Abstract: 1476011 Charging batteries in systems having two power sources NISSAN MOTOR CO Ltd 10 June 1975 [10 June 1974] 24776/75 Heading H2H In a supply system of the type wherein a load 16 (e.g. motors of an electric vehicle or a submarine) is supplied through a conventional chopper circuit 18 from one or both of a pair of batteries comprising a high energy battery 12 and a high power battery 14, the former being higher in open-circuit voltage and larger in capacity but lower in maximum output than the latter and wherein the battery 14 is charged by the battery 12 during periods when the current required by the load 16 is small enough to be supplied primarily by the battery 12, the charging current is controlled by a conventional chopper circuit 26 responsive to a control circuit 28 which receives signals from sensors 30, 32 respectively indicative of the residual capacity of the battery 14 and the current therethrough, the operation being such that when the capacity is at or below a lower limit C L  the chopper 26 is continuously conductive and when the capacity has risen to an upper limit C H  the chopper 26 is cycled at the same frequency as the chopper 18 and the energy supplied to battery 14 during each on/off cycle of chopper 26 is close to but less than the energy discharged from the battery 14 during each preceding on/off cycle of the chopper 18. Thus the battery 14 is rapidly charged from its lower to upper capacity limit and gradually discharges from the upper to the lower limit, Fig. 5 (not shown). This reduces the number of charge/discharge cycles of the battery 14 compared with a known system, Figs. 1, 2 and 3 (not shown), for load currents whose mean value is less than the minimum value theoretically requiring current from both batteries 12, 14, but whose peak value (due to the action of chopper 18) is such that both batteries are caused to discharge. Typical cycles of operation of the choppers 18, 26 are discussed. Fig. 6 (not shown)

As shown in Fig. 3 each shaft 17 has discs 19 splined to it and pressed by springs 25 towards discs 15 carried by the hub 11, there being rollers 22 carried by cages 21 between discs 15 and 19 and engaging recesses 23 and 24 in the discs to prevent rotation of shaft 17 until the springs 25 are overcome by the torque to allow the rollers 22 to ride out of the recesses. The rotation of shafts 17 allows teeth 30 to leave apertures 28 and so disengage the clutch. The bearings 31 are spring 32 biased outwards to facilitate manual resetting of the clutch, a pin 35 holding the driving and driven members in position for this operation. The clutch may be used in a rolling mill, where very high torques are to be accommodated. Springs 25 may be replaced by hydraulic or pneumatic means. The springs 25 are adjustable in their bias through nuts 26. The rollers 22 may be replaced by balls.

Sept. 4; 1931, No. 24912. Convention date, Sept. 15, 1930. [Class 40 (ii).] In an optical system for reproducing sound wherein a beam from a light source is focused by a lens system on to a slit and passes through another lens system which focuses it on to a film, the angular subtense of the beam directed on to the film is smaller than usual whereby loss of resolution of the higher frequencies when the film becomes displaced laterally in its travel is reduced. The slit between the lens systems may be reduced in depth below the usual and the beam directed thereon at a wider angular subtense to maintain the normal slit factor, that is the product of slit depth and angular subtense of beam, and the lens system directing the beam on the film may magnify the slit image at the film to normal size. The Figure shows the arrangement ; the angular subtense 23 of the beam directed by the objective lens system 6, 7, 8 on to the film is reduced below the usual, for example to 17‹, and the slit 5 has a reduced depth and the angular subtense 21 of the beam directed thereon by the lens system 2, 3 is increased, for example to 26‹, a magnified image of the slit being produced on the film by the lens system 6, 7, 8.
