Title: Hydraulic master cylinder assembly
Inventor: MOCHIZUKI TOYOJU
IPC: B60T11/20
Filed: 1969-01-02
Abstract: 1,211,331. Hydraulic master cylinders. T. MOCHIZUKI and M. WATANABE. 2 Jan., 1969[11 Jan., 1968], No. 206/69. Heading F2F. In Fig. 1, when the push-rod 4 is actuated by the driver of the automobile, the primary piston 5 is impelled to the right, permitting tilting valve 13 to close. The resulting pressure in the primary hydraulic chamber 12 acts on the rear brake cylinders through port 16, acts on the secondary piston 9, and acts on a relay piston 22 in a relay cylinder 15. The preliminary movement of piston 9 to the right permits tilting valve 19 to close; downward movement of the relay piston 22 permits admission of atmospheric air from 14 to chamber 23 on the left of actuating member 11 attached to diaphragm 10. Piston 9 is thereby pulled to the right and compresses fluid in the secondary hydraulic chamber 18 communicating at 20 with the front brakes. The pressure transmitted from chamber 18 is thus higher than that transmitted from chamber 12. The engine intake manifold is connected at 25, so diaphragm 10 is normally vacuumsuspended. If leakage occurs in the system of chamber 12, piston 5 moves under the influence of push-rod 4 until it makes contact with protrusion 31 of secondary piston 9. At this stage, piston 5 has mechanically depressed piston 22 by means of a tongue 32, so the servo-motor 8 operates piston 9 and application of the front brakes is unaffected by failure of system 12. If leakage occurs in the system of chamber 18 the pressures on piston 9 bring it up against a nut 17 at the rear end 7 of the cylinder, and pressure from chamber 12 acts, unimpaired, on the rear brakes. Fig. 2 differs from Fig. 1 in that, instead of tongue 32 being provided, piston 5 is provided with a tapered portion 34, and in that piston 9 is now in two parts 9a, 9b, with a valve 33 between the parts taking the place of tilting valve 19.

Title: Improvements in and relating to ring spinning and twisting frames
IPC: D01H1/36
Filed: 1931-01-05
Abstract: 362,716. Spinning upon the bare spindle or upon tubes in ring frames. LAURENCY, G. C., 30, Rue de la Mazrine, La Hulpe, Belgium, and MAcLEAN, G., Villa La Case, Dieppe, France. Jan. 5, 1931, No. 410. [Class 120 (ii).] Bobbins or cops adapted to be unwound regularly and without entanglement are spun and wound in ring frames upon the bare spindle or upon tubes by reciprocating the spindles to lay the yarn in elongated windings and imparting a rapid reciprocation to the rings when the spindles are at the bottom of their stroke, whereby a change in the winding angle at the nose represented by the lines CD, CE, Fig. 9, is effected. The length of the chase is varied to form the cop bottom or core by imparting a further variable reciprocation to the ring rail which is also raised to build the cop. The spindle rails are reciprocated through a lever 16 and chain 17 by an internal cam 15, which is shaped to impart a uniformly retarded upward movement and a uniformly accelerated downward movement and to ensure a sharp reversal of movement. The ring rails are operated by chains 25 displaced by a bowl 24 on a lever 23 which is actuated by a chain 32 from a lever 31 operated by an adjustable stop 29 on the lever 16. The movement of the ring rails at the nose of the cop is effected by stops 36, 37 which displace the lever 23 and are carried by a plate 14 adjustably mounted by means of slots and bolts 38, 39 on the cam plate 15. The stop 29 is suitably shaped and engages a suitably shaped cam lug 30 on the lever 31 so that, in conjunction with the adjusting screw 28, the extent and duration of the movement imparted to the ring rail is varied to form the cop bottom, the stop 29 passing out of range of the cam lug 30 when the bottom is formed. The chain 25 is additionally operated by a screw 26 and ratchet 27 to effect the building of the cop. The ring rails are balanced by bars 46 supported by chains 49, 50 and interposed springs 47, 48.

Title: Improvements relating to surgical sponge sticks
IPC: A61B17/22
Filed: 1966-01-07
Abstract: A surgical sponge stick comprises a tubular handle of resilient plastics material having a partially flattened portion with perforations through its wall at one end with porous absorbent material forming a surgical sponge (or swab) mounted on said end covering the perforations.  The pastics material may be polyethylene, polypropylene, or polystyrene.  The porous absorbent material may be gauze or an elastomeric synthetic sponge material, e.g. polyurethane, polyethylene, or polypropylene foam. The tubular handle may contain a holder for release of an appropriate liquid, e.g. antiseptic or sterilising liquid, to the sponge.  For this purpose, the liquid may be contained in a frangible container made of thin, brittle, plastics material, e.g. polystyrene, which will break when the handle is squeezed. Alternatively, a piston-plunger arrangement may be used (if Fig. 5, not shown).  The sponge may be secured to the handle by stitching or by adhesive, e.g. silicone adhesive, or by friction. The handle may be connected to a source of suction, e.g. a vacuum pump or chamber, by rigid or swivel couplings (see Figs. 12 to 15, not shown).  The perforations may be on one or all sides of the partially flattened portion.  An impervious plastic shield may be inserted between the sponge and perforated end of the handle to prevent suction over a particular area (see Fig. 18, not shown). The sponge may be provided with a support means or framework made of appropriate metal wire or plastics material (e.g. stainless steel, polyethylene or polystyrene) so that the sponge stick may be used as a retractor (if, Figs. 6, 16, and 17, not shown).
Patent GB-923246-A (GB)
Title: Conversion of residual oil to gasoline
IPC: C10G69/06
Filed: 1961-01-09
Abstract: Heavy, residual hydrocarbons are converted to gasoline and other products by coking and recovering a gas oil fraction, treating this to reduce the nitrogen content below 10 p.p.m., and contacting together with at least 500 preferably at least 2,000 SCF of hydrogen per barrel with an acidic cracking catalyst having hydrogenating characteristics at 350-700 DEG F. and at least 400 p.s.i.g. to convert at least part to gasoline.  The feed, e.g. a reduced crude, is subjected to delayed or fluidised coking.  The gas oil may be recovered from the product as two fractions, a heavy and a light gas oil.  The former may be subjected to conventional thermal or catalytic cracking to obtain gasoline and heavy and light cycle oils. The heavy cycle oil is used as jet fuel or recycled to the cracking while the light cycle oil is added to the light coker gas oil and the combined feed is denitrified.  Alternatively a portion of the heavy gas oil may be recycled to the coking step or passed with the light gas oil to the dinitrification.  This latter step is effected by washing with acid, contacting with solid acidic material or, preferably, by hydrofining.  The hydrocracking catalyst comprises an acidic cracking catalyst, e.g. SiO2-MgO, SiO2-Al2O3-ZrO2, acid treated clays, synthetic metal alumino-silicates including molecular sieves, synthetic SiO2-Al2O3, Al2O3-AlCl3, fluorided magnesia, aluminium chloride or charcoal, HF-BF3, TiCl3 or AlCl3-hydrocarbon-HCl complexes, together with a hydrogenating component forming 0,1-35% of the catalyst, e.g. a compound of a metal of Group 1B, 2B, 5, 6, 7 or 8 which is not reduced to the metal under reaction conditions such as oxides or sulphides of Mo, W, Cr, Re or Zn and sulphides of Co, N1, Cn or Cd or Co-Cr or Ni-Cr complexes.  In the hydrocracking the space velocity may be 0,2-5 and the pressure 400-3,000 p.s.i.g. Product boiling above 400 DEG F. may be recycled or used as jet fuel. Heavy gasoline product from any stage and particularly from the hydrocracking may be catalytically reformed. Specification 917,943 is referred to.

Abstract: 1332721 Electrically heated windows SPIEGELGLASWERKE GERMANIA ZWEIGNIEDERLASSUNG DER GLACERIES DE SAINT-ROCH SA 8 Jan 1971 [8 Jan 1970] 994/71 Heading H5H An electrically heated window for an automobile has zones 31, 32, 33 in which greater heating takes place than in intermediate zones 34, 35. In Fig. 3 the heating conductors comprise horizontal bands of baked metallic deposit, applied by the silk-screen method and reinforced by electro-deposition. The bands in zones 34, 35 are given a wider cross-section thus reducing the heating effect in these zones. Alternatively the variation in resistance across the bands may be effected by differential electrodeposition of a metal, carried out after the deposition and baking of bands of a uniform cross-section. Alternatively heating may be achieved by resistance wires arranged vertically, the spacing being varied according to the heating required in the different areas, or the resistances may be in the form of transparent coatings, such as tin oxide or a layer of gold between two layers of bismuth oxide.
