Title: Improvements in or relating to Domestic Cleaning Appliances.
Inventor: GREEN WILLIAM
IPC: A47L11/38
Filed: 1918-02-25
Abstract: 123,574. Green, W. F'eb. 25, 1918. Buildings and the like, cleaning.-A domestic cleaning-appliance for household fittings comprises a cleaning-member such as a brush, cloth, rubber, wire, or the like mounted on hinged and telescopic tubes or rods so that it can be brought into contact with any fittings within its range of action. The tubes or rods may be supported on the fitting to be cleaned or on the walls, ceiling, or floor of the room. Fig. 1 shows one form of apparatus for cleaning water-closet seats. in which a brush a is rotated by contact with the seat b. A spring h keeps the inner end of the brush in contact with the edge of the seat. In this case, the brush is supported from a wallbracket e to which is hinged an arm f jointed at f<1>. A handle g<1> serves to manipulate the brush over the seat. As shown in Fig. 2, the brush may be adapted to supply cleaning or disinfecting liquid to the fitting. In this case, the liquid is stored in the hollow shaft h, and escapes through perforations h<1> and a<3> to the bristles. A segment j inside the hollow shaft normally covers the holes h<1>, but is arranged to uncover them once during each revolution of the brush to provide an intermittent flow of cleansing-liquid. Rotation of the segment is caused by the members j<1>, j<2> which connect it to the outer ends of the brush. The hollow shaft is charged with fluid by removing the cap h<2> or by fitting a cap under the handles g<1>, in which case the member g is used as an additional reservoir. In lieu of a rotary brush, a multiple-sided brush may be used, each side of which is adapted to perform a different function, the brush being turned at intervals to present different sides to the article being cleaned. For cleaning lavatory pans, a vertically ranging mop or the like is secured to the lower end of the tube g. In this case, the cleaning fluid escapes through perforations at the bottom of the tube on to the mop. A flat segmental plate, operated from a knob adjacent to the handle g<1>, can be rotated inside the tube to cover or uncover the perforations. Fig. 5 shows a brush l for cleaning lavatory basins fitted on a second lateral arm at the lower end of the telescopic rod m corresponding to the rod g in Fig. 1. The apparatus, when not in use, may be mounted in a box or chamber containing cleaning or antiseptic preparation, and may be withdrawn from the chamber against the action of a spring which returns it to the chamber when released. An attachment a<5>, Fig. 6, on the brush, when entering the storage chamber, operates a sliding valve l<3> against the action of a spring n and opens communication between the reservoir l<1> of antiseptic liquid and the main storage chamber, so that the antiseptic liquid drips on to the brush. Fixed brushes may be fitted in the main chamber in contact with the bristles of the brush.

Title: Process for the polymerization of propylene
IPC: C08F4/631
Filed: 1964-01-28
Abstract: Polypropylene having a high isotactic content is made by polymerizing propylene in the presence of a catalyst obtained by reacting an organometallic compound with a complex compound obtained by interaction of sulphur and a transition metal lower halide, such as a trichloride of vanadium, zirconium, or titanium. The complex appears to consist in the case of Ti, of TiSCl2 (about 70%) and of TiSCl (about 30%).  The organometallic compound is preferably triethyl aluminium or diethyl aluminium chloride.  The polymerization is generally effected in a hydrocarbon diluent and the polymer recovered by conventional techniques, e.g. addition of methanol, and steam distillation in the presence of sodium hydroxide.ALSO:A complex, suitable as a polymerization catalyst component, is made by interacting sulphur and a transition metal lower halide, such as a trichloride of vanadium, zirconium, or titanium.  The complex appears to consist, in the case of titanium, of a mixture of TiSCl2 and TiSCl.  The reaction between the sulphur and the lower halide is effected at elevated temperature and may be carried out in the solid state but, preferably, it is effected in a hydrocarbon solution.  Two examples are given of the preparation of this complex.  In Example (1), sulphur as a solution in benzene is reacted with purple TiCl3, in an autoclave, at 120 DEG  C. for 8 hours, whilst in Example (2), the procedure is the same as in Example (1), except that the purple TiCl3 is replaced by brown beta-TiCl3.

Abstract: 764,370. Turning-gear. BENDIX AVIATION CORPORATION. Feb. 8, 1955 [Feb. 24, 1954], No. 3733/55. Class 7 (5). In an engine starter drive comprising a power shaft 1, a driving clutch 'sleeve 2 fixed thereon and having teeth 4, a hollow screwshaft 5 with clutch teeth 6, the screwshaft being slidably journalled on the sleeve 2, a spring washer 9 holding the teeth 4 and 6 in contact, an externally and internally threaded control nut 11 on the screwshaft, a stop ring 7 on the sleeve limiting the longitudinal movement of the nut 11, a pinion 14 slidably journalled on the power shaft 1 for movement into and out of mesh with a gear 15 of the engine to be started, and a barrel 16 splined to the pinion 14, and threaded on the nut 11, a drive spring 28 connects the nut 11 to the barrel. One end of an outer barrel 22 is secured on a flange 24 of the nut 11 whilst the other extremity has an anchor plate 25 fixed thereto and bearing on the barrel 16 ; the spring 28 is connected between the plate 25 and a flange 27 formed on the barrel 16, a shoulder 32 in the outer barrel 22 being engaged by the flange 27 to limit the meshing movement of the barrel 16 with respect to the nut 11. A spring-loaded latch-member 34 is mounted in the nut and a mesh-enforcing spring 37 is located around the power shaft between a pinion flange 18 and a thimble 38 abutting the nut extension 19. Rotation of the power shaft 1 is transmitted to the screwshaft 5 via the overrunning clutchteeth 4, 6 whereby the nut 11 threads rightwardly pushing ahead of it the pinion 14 and the barrel 16 through the spring 37 until the nut 11 is arrested by the stop 7 after the pinion has initially meshed with the engine gear 15; the nut 11 is thereby compelled to rotate with the screwshaft whereupon the barrel 16 is translated to the right causing compression and torsion of the drive spring 28 which movement effects complete meshing of the pinion so that the flange 27 abuts its shoulder 32, just prior to which the barrel 16 runs off the threads 21, and the engine is cranked through the drive spring 28. When the engine fires the barrel 16 threads itself back onto the nut 11 but the pinion 14 is maintained in mesh by the latch 34 until the engine is reliably self operative .and the latch is centrifugally withdrawn to enable the parts to return to the inoperative position shown wherein they are retained by the latch.

Abstract: 543,819. Reciprocating pumps for liquids. ARMSTRONG, J. J. V. (Vickers, H. F.). March 28, 1941, No. 4169. [Class 102 (i)] [Also in Group XXIX] In a hydraulic transmission device of tne kind comprising a pump and a motor of the reciprocating piston and rotary valve type an auxiliary bearing surface is provided in connection with the valve which controls the flow of fluid to or from the cylinders of the pistons 24 which are actuated by an adjustable swashplate device. As shown, the pump cylinder barrel 44 is mounted in a yoke 32 adjustable about trunnions 38 forming part of the fluid inlet and outlet, and the barrel is driven from a shaft 16 by means of a rod 52 connected by universal joints 54 to a socket flange 18 and to the barrel the flange being fitted with ball sockets 20 for receiving connecting-rods 22 attached to the pistons 24. The barrel 44 has outlets 50 which register with a pair of segmental inlet and outlet grooves 48 in the valve plate 34 forming part of the yoke 32. The barrel is pressed by a spring plunger into contact with the valve and the structure is designed to constitute a hydraulic balance. To prevent errors due to inaccurate machining which would upset this balance an auxiliary bearing is provided between the face 40 ot the valve and the face of the barrel 44 having the form of a number of segmental pads 56 let into the valve face and formed with depressed parts or chambers 58 forming liquid receiving chambers which are supplied with fluid by a metering device comprising a chamber 70 connected by passages 72, 74, 62, 60 to the chambers 58 and supplied with fluid by a valve 78 controlled by a spring piston 80 connected at one end by a passage 88 to the end of the restrictor passage 72 and at the other end by a passage 86 to the chamber 70. A constant pressure drop is maintained across the restrictor 72 and oil is delivered at a constant minute rate to the chambers 58. The oil has to escape between the surfaces of the valve and barrel and so ensures a constant slight clearance between them which can be adjusted to ensure a hydraulic balance which is restored automatically if upset. The chambers 58 may be fed individually by separate devices, and the invention may balance thrusts in other situations, e.g. between the flange 18 and the thrust bearings 14. The invention may be applied in reversible machines where either port 30 may be the pressure port. Specification 538,746 is referred to.
