Title: Air brake valve
IPC: B60T13/40
Filed: 1965-01-08
Abstract: 1,062,223. Fluid pressure brakes; valves. LANCIA & C. FABRICA AUTOMOBILI TORINO S.p.A. Jan. 8, 1965 [Jan. 8, 1964], No. 1040/65. Headings F2F and F2V. An automatic regulating valve 100 in a tractor/trailer compressed air braking system between a trailer brake reservoir 10 mounted on the tractor and trailer brake service delivery conduit 22b, normally connected through the valve to atmosphere, and trailer brake emergency delivery conduit 22a, normally connected through the valve to the reservoir, comprises means on brake application, for closing conduit 22b with respect to atmosphere and connecting it to the conduit 22a and for also automatically isolating the reservoir 10 from both interconnected conduits in the event of damage to the conduit 22b. The system comprises compressors 1 and 2 supplying compressed air to reservoirs 7, 8 and 10 through regulators 5 and 6. Ducts 11 and 12 connect reservoirs 7 and 8 to pedal-operated distributers 13 and 14 which are connected through ducts 16 and 18 to rear brake actuators 17 and front brake actuators 19 of the tractor and also to chambers 112 and 111 of the valve on either side of a diaphragm 110 slidably mounted above a diaphragm 109 fixed to a hollow stem member 107. Said stem normally maintains a closure member 114 open to communicate conduit 22a with reservoir 10 through chambers 101 and 102, and allows closure member 116- to seat preventing communication between conduits 22a and 22b through chamber 102, duct 105, chamber 104 and chamber 103, but allows conduit 22b to vent to atmosphere through a hole in the hollow stem and chamber 106. On depression of the pedal 15, compressed air is supplied to front and rear tractor brake actuators and to valve chambers 111 and 112 causing diaphragm 109 and stem 107 to be forced to abut the latter on closure member 116 simultaneously preventing further venting of conduit 22b through stem 107 and supplying compressed to said conduit from reservoir 10 through chamber 101, the still open closure member 114, conduit 105, open closure member 116 and chamber 103 to apply the trailer brakes (not shown). Should conduit 22b fail, pressure is lost in chamber 103, stem 107 moves down, and closure member 114 seats to isolate both conduits from reservoir 10, the fall in pressure in line 22a resulting in the trailer brakes being fully applied in a known way by a reservoir on the trailer itself. In a modification, Fig. 1 (not shown), diaphragm 110 is deleted and the resultant single chamber 118 connected to a single circuit of the tractor brake system.

Title: Improvements in or relating to reversible ploughs or like agricultural soil-working implements
IPC: A01B3/30
Filed: 1950-01-16
Abstract: 674,433. Reversible ploughs. CHARRUES MELOTTE SOC. ANON. Jan. 16, 1950 [Jan. 15, 1949], No. 1108/50. Class 6(i) A reversible plough comprises a longitudinal beam 2 rotatably mounted in a fore-carriage 4 supported on a cranked axle 1, the movement of which, on the raising or lowering of the plough, applies tension to a spring 26, this tension being subsequently utilized to reverse the plough bodies. The reversing mechanism employed is that described in Specification 468,127 and comprises a ring 6 encircling the beam 2 and carrying ratchet teeth 10 alternately engageable with one of two spaced pawls 8 on the beam, the ring being rotated by a pull on a chain 17. The chain is connected to an end of a lever 25, the other end being attached to the spring 26. In the construction shown, the spring is anchored to an arm 20 secured to the cranked axle 1 and the fulcrum 24 is carried by a bifurcated upright 23 resting on a cam surface 21 integral with the lever 20. The upright 23 is pivoted to the forecarriage frame 4 by parallel links 27, 31, the lower link being extended at 31<SP>1</SP> to form a detent engaging alternate diametrically-opposed notches 33 in a disc 34 secured to the beam 2. The fore-carriage is raised by anticlockwise rotation of the axle 1, thus extending the spring 26. At the end of the lifting, the member 23 slips off the cam 21, thus tilting the link 31 and unlocking the detent 31<SP>1</SP>. The spring 26 then reverses the shares, through the arm 25 and chain 17 acting on the reversing mechanism. In a second construction, Fig. 3 (not shown), the spring is tensioned during the previous lowering, and the subsequent raising of the' plough is permitted to occur without releasing the spring tension through a link system incorporating lost-motion. As in the previous construction, the reversing mechanism is automatically unlocked, at the end of the raising, to allow the loaded spring to effect inversion.

Title: Improvements in or relating to the interpolymerisation of vinyl chloride with fumaric esters
IPC: C08F214/06
Filed: 1943-01-22
Abstract: Vinyl chloride in admixture with a fumaric diester is emulsified in an aqueous medium containing a dissolved salt of perdisulphuric acid and an "acid-stable" dispersing agent comprising an acyclic long-chain (12-18 carbon atoms) hydrocarbon substituted with only one radical of formula -SO2X or -OSO2OX where X = alkali metal, and then polymerized at a temperature between the freezing point of the aqueous phase and 80 DEG  C.  By "acid-stable" dispersing agent is meant one whose activity is unaffected in media of pH 3-5, specified dispersing agents include the alkali metal salts of long-chain alkyl sulphates and sulphonates, e.g. dodecyl, tetradecyl and octadecyl acid sulphates, dodecane, tetradecane, hexdecane and octadecane sulphonic acids; and salts of long-chain paraffin oil hydrocarbons. The polymerization system may also contain inorganic salts, long-chain primary alcohols, carbohydrate derivatives and polyvinyl alcohol.  It is preferred to carry out the process in an oxygen-free atmosphere.  The fumaric ester may be added in portions to the vinyl chloride emulsion during the polymerization.  Preferred fumaric diesters are esters of aliphatic, hydro-aromatic, aromatic and monohydric ether alcohols; specified are methyl, ethyl, isobutyl, n-butyl, cyclohexyl, benzyl, or chloroethyl diesters and diesters with methyl, ethyl and butyl glycol ethers.  Optionally, other polymerizable compounds may be present, e.g. vinyl esters, acrylates, methacrylates, acrylonitrile, methacrylonitrile, styrene, asymmetrical dichlorethylene or methyl vinyl ketone.  Before precipitation of the polymeric product small amounts of heat and light stabilizers, e.g. epichlorohydrin, may be added.  The polymers may be combined with or prepared in the presence of stabilizers, fillers, pigments, dyes, softeners, natural or other synthetic resins, and plasticizers, e.g. dibutyl phthalate, tricresyl phosphate and dibutyl sebacate.  Examples are given. Specification 570,330 is referred to.

Abstract: 1,126,441. Carburetters. M.P.G. &H. ENGINEERING Ltd. April 11, 1967 [Jan. 11, 1966], No. 1259/66. Heading F1B. The invention relates to carburetters of the type including an air passage or choke tube, a butterfly throttle member A1 located in the choke tube, the throttle member having fuel distributing nozzles in its surface, a segmental fuel chamber B an arm secured to the throttle member and movable arcuately in the chamber about the axis of rotation of the throttle member and a passage B12 in the arm connecting with the nozzles in the throttle member and opening into the fuel chamber. The invention comprises a carburetter of the above type in which nozzles on opposite sides of the spindle are constituted by a plurality of holes distributed longitudinally of the spindle across the air passage or choke tube and the holes on the upstream side of the throttle member when it is disposed so as to cause maximum constriction of the air passage or choke tube are of larger size than the holes of the downstream side. The chambers B and C Fig. 1 (not shown) are arranged to be bolted between the choke tubes A, D. The relative disposition of the chokes and of the chambers may be either as shown in full lines or as shown in dotted lines or at any intermediate position simply by altering the position of the drillings. As shown the fuel supply chamber is of the weir type. As an alternative however the chamber may be constructed as a float chamber. At the free end of the arm 1 is a pick up jet B3 suitably of nylon which is spring-loaded suitably by a spring washer so that the head of the jet can be resiliently urged flush with the face of the arm, when the arm is opposite and bears on the plane face portion of the side wall of the chamber B. When the arm is rotated (fully clockwise in Fig. 2) when the throttles are closed, the jet B3 is brought opposite the plane face portion of the side wall of the chamber B and is obturated. In this position drilling B4 is uncovered thus drilling communicating with the choke tube downstream of the throttle A1. An adjustable needle screw B5 controls the passage of fuel through the drilling B4 which latter constitutes an idler jet supplying fuel at closed throttle settings. The drilling B4 may be arranged to communicate with both choke tubes. British Specifications 859, 777 and 1, 126, 442 and U. S. A. Specification 2, 801, 086 are referred to.

Title: Data processing system
IPC: H03M7/40
Filed: 1972-01-13
Abstract: 1332631 Decoding variable length words INTERNATIONAL BUSINESS MACHINES CORP 13 Jan 1972 [26 Feb 1971] 1561/72 Heading G4C Variable length prefix free input code words are decoded to fixed length code words by examining successive groups of bits of the input word, each group being used to derive an address in an appropriate decoding table which is then accessed either to derive the fixed length word or to derive a new address which is used in combination with the old address and the address obtained from the next group of bits to access the decoding table. As described a group number is first determined, either from the previously decoded character or from initial condition. This gives the address in the memory of a label and a mapping table address. The label contains the number of bits in each of the successive groups or windows to be examined and also the address D 0  of the associated decoding table. The contents of the first window are examined and used together with the address D 0  to produce an entry address D 0  + a 1  for the decoding table which is then accessed to determine whether decoding is possible or not. If decoding is not possible the address a<SP>1</SP> stored in the access portion of the decoding table is held together with the old address D 0  + a 1 . The contents of the next window are examined to produce an address a 2  which is added to the previous addresses to provide a new address in the decoding table. This is then accessed to see if decoding is possible or if a new address is stored. For a successful decode the word in the accessed part of the decoding table has a first "1" bit indicating that decoding is possible, a section indicating the number of bits in the variable length code representing the character (so that the beginning of the next character may be located) and either, for independent coding, the fixed length binary code word representing the character, or, for dependent coding, the address in the mapping table which is used in conjunction with the mapping table address indicated by the initially selected group to access the mapping table to derive the fixed length code word.
