Filed: 1974-03-25
Abstract: 1467272 Valves AUSTRALIAN IRON & STEEL PTY Ltd 25 March 1974 [2 April 1973] 13214/74 Heading F2V Two hydraulically-operated devices, such as an extendible leg 8, Fig. 1, and a chuck 63 for a drill are independently controlled by valves 24, Fig. 7, and 22, Fig. 4, respectively, supplied from a common inlet 9 through a pressure responsive valve 13 which throttles the flow to one valve to compensate for pressure changes in the flow to the other valve. The valve 22 is adjusted axially against a spring 58 by a handle 62 to regulate the flow to a motor 7 driving the chuck while the valve 24 is rotated through gearing 52, 53 by a hand lever 55 on which the handle 62 is pivoted, the valve 24 having a first position in which fluid is supplied to a passage 29 to extend the leg, a second position in which the leg is locked and the fluid supply is returned to tank and a third position in which fluid is supplied to a passage 30 to retract the ]eg. Excessive pressure in the supply to the leg is prevented by a pilot operated relief valve in a passage 23 leading from a chamber 19 to the valve 24. The relief valve may be designed to provide progressive relief pressure. The chamber 19 contains a spring 15 for the pressure responsive valve 13 and communicates with the common inlet 9 through a throttle 17 which may be pre-set. The leg 8, Fig. 2, may have a first portion 69 extended by the application of fluid pressure through the passage 29 to a piston 71 until a stop 74, engages a cap 68 when a second portion 77 is similarly extended by a piston 80 until a stop 83 engages a cap 76. Fluid from the spaces below the pistons is returned to a line 30 through apertures 91, 92, passages 87 and a tube 88. To retract the Cg, fluid is supplied to the line 30 and withdrawn through the passage 29. Specification 1,467,273 is referred to.

Title: Improvements relating to the damping of vibrations in members
IPC: G01C21/18
Filed: 1941-10-14
Abstract: 549,893. Damping vibrations. ARNOLD, R.N., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Oct. 14, 1941, No. 13223. [Class 108 (iii)] [Also in Group XX] Torsional oscillations of a rotating or non-rotating shaft 1 about its axis X-X produce vibratory precession of a gyroscopic system having a definite natural frequency of vibration about its precessional axis Y-Y on which is mounted energy absorbing means 11. Torsional or other vibration may be converted into torsional vibration of the shaft by gearing 2, 3 or 2, 4. The gyroscope 7 rotates about axis Z-Z and is mounted in a gumbal 8 carried by bearings in brackets 10 on the disc 6 secured to shaft 1. Movement of the gimbal 8 is limited by springs 13, 14 selected to give a predetermined natural frequency about axis Y-Y. Vibrations are absorbed by the fluid or other damping means 11. Where the system is in operation, the principal axis Z-Z is approximately at right angles to the axis X-X. If the shaft 1 is rotating, springs 13, 14 are adjusted so as to give an initial bias of the axis Z-Z towards position Z<SP>1</SP>-Z<SP>1</SP> so that the gyroscopic torque due to the mean rotational speed of shaft 1 will maintain the system in position Z-Z.

Title: Improvements in and connected with extrusion apparatus for licorice and other materials
IPC: A23G3/00
Filed: 1954-05-06
Abstract: 770,664. Filters ; presses for separating liquids from solids. LAMPERD, A. A. May 6, 1954 [May 8, 1953 ; Aug. 14, 1953], No. 13245/54. Class 46. [Also in Group V]  Licorice or other confectionery material is forced by a screw 22 into a cylindrical sieve 23 and is forced outwards, at the same time as it moves axially through the sieve, through the perforated wall into an annular space between the sieve and a hollow cylinder 24. The sieve is clamped between the end of the screw cylinder 21 and an end plate 32 which is flanged so as to hold the flared end of the sieve against the end of a comparatively massive end ring 26. The sieve is supported intermediately by rings 25 threaded on studs 28. After being sieved the material passes through pipes 51 to a gear impeller 56 comprising a casing housing intermeshing gear wheels 64 which are driven by a chain 66 from the main drive through variable speed means, not shown, whereby the impeller may be adjusted to suit the rate of delivery through the pipes 51. The pipes 51 end in a plate 80 which has a channel 81 aligned with the interior of the impeller, providing a passage for the material, and the plate 80 is held between the flanges of bars 71 and a wedge 72, giving a quickly-detachable connection. The wedge is pressed in or withdrawn by a handwheeloperated screw. The die plate 73, at the outlet of the impeller, is similarly connected. Material extruded through the die is delivered onto a moving belt 82. The end plate 32 provides a bearing for the end of a shaft 40 which is an extension of the screw 22 and carries arms 42 regularly spaced on it and carrying wipers 45, Fig. 3, which are U-shaped members pivoted on the arms with blunt leading edges 49 and rubbing surfaces 47 shaped to the curvature of the sieve 23. Thus the material presses the wiper against the surface of the sieve. A projecting pin 50 on each wiper prevents it from pivoting too far inwards, by striking the arm 42, In addition to the pipes 51 an outlet is provided from the space surrounding the sieve by a pipe 53 which acts as a by-pass and returns a proportion of the material to the cylinder 21 for further milling and filtering. The end plate 32 is held against the end ring 26 by curved spring bars 34, Fig. 7, hinged at one end to a bracket 35 on the cylinder 24 and at the other end to a strap 36 which is in turn hinged to a catch plate 37 engageable behind a lug 38 on the cylinder 24, whereby the spring bars 34 are drawn against the end plate 32 and slightly bent. Material accumulates at the end of the sieve, inside the ring 26, and a plug is provided through aligned holes in the ring and sieve which may be withdrawn to remove excess material.

Patent GB-611495-A (GB)
Title: Improvements in and relating to the treatment of chloromethyl-substituted polysiloxanes
IPC: C08G77/16
Filed: 1946-05-02
Abstract: Polymers containing silicon-bonded chlorinated methyl groups are heated with an alkaline material in presence of moisture to remove the chlorinated methyl groups.  Suitable alkalies are caustic potash, ammonia, sodium carbonate, basic metal oxides and organic salts of basic metal oxides.  The polymers may be prepared from methylchlorosilanes chlorinated according to the processes described in Specifications 575,667, 575,668 and 575,669, [Group III]. Polysiloxanes containing silicon-bonded chloromethyl radicals may be converted by this method to silicols and thence to higher molecular weight polysiloxanes.  In the examples: (1) Dimethyl (dichloromethyl) chlorosilane was hydrolysed by pouring into water.  The separated sym-tetramethyl-bis-(dichloromethyl) disiloxane was treated with aqueous potassium hydroxide.  A viscous oil was the product.  (2) Methyl di - (chloromethyl) chlorosilane was hydrolysed and condensed to dimethyltetra-bis-(chloromethyl) disiloxane which was heated with caustic potash.  (3) Methyl (trichloromethyl) dichlorosilane was hydrolysed and the resulting oil treated with caustic potash.  (4) Sym - tetramethyl - bis - (dichloromethyl) disiloxane was warmed with moist sodium carbonate.  Methylene chloride was evolved and the molecular weight of the product increased.  Examples (5), (6) and (7) also employ sym - tetramethyl - bis - (dichloromethyl) dichloromethyl) disiloxane, which is heated with: example (5) aqueous sodium carbonate and n-butanol; (6) lead oxide; (7) an oil-soluble form of basic metal oxide "Nuodex" (R.T.M.).  The chloromethyl groups are not split off under acidic conditions, so that siloxanes structures containing chloromethyl groups can be formed under acidic conditions and subsequently treated to increase the molecular weight. In example (8), heptamethyl-chloromethyl-cyclotetrasiloxane was polymerized to a toluene-soluble gum with ferric chloride as in Specification 585,628.  The gum was compounded on milling rolls with 1 per cent of lead oxide and titanium dioxide as a filler and formed into sheets which were then cured at 150-200 DEG  C.  The products were similar to those of Specification 594,481.

Abstract: 553,273. Hydraulic control mechanism; fluidpressure brakes. CLAYTON DEWANDRE CO., Ltd., and EDGE, S. H. Oct. 20, 1941, No. 13475. [Class 69 (ii)] [Also in Group XXXIV] A single-acting hydraulic motor q, Fig. 1, which may operate a brake, or a sliding-valve rotary motor s, Fig. 3, is actuated by a gear pump b which in the inactive position circulates liquid through a by-pass valve l to a pipe d leading back to the reservoir a. To build up pressure in the motor the by-pass valve l is throttled or closed by depressing a piston k, to which the valve l is attached, by means of a lever h acting through a piston f and a spring j, or two or more springs brought into action successively. The pressure applied to the hydraulic motor is thus proportional to the effort applied to the lever h. The pressure fluid at all times can act upon the piston k.
