Title: Hydraulic axial piston type motor
Inventor: RAYMOND ROBERT EVANS
IPC: F03C1/32
Filed: 1966-02-24
Abstract: 1,126,561. Hydraulic reciprocating motors; centrifugal pumps. INTERNATIONAL BASIC ECONOMY CORP. Feb.24, 1966, No.8198/66. Headings F1A and F1C. An axial piston hydraulic motor comprises a non-rotatable cylinder block 56 with pistons 66, Fig. 1, engaging a rotatable swash plate 40 through slippers 47, e.g. of nylon, held against the swash plate by a nutating plate 78, e.g. of nylon, and a rotary pintle valve 90 driven by the swash plate through coupling 100, the cylinder block being removably mounted for axial movement in the housing by bearing members 58, Fig. 2, and being vibrated axially to reduce breakaway friction for starting. The axial vibration may be effected by supplying hydraulic pulses, e.g. from a pump, to annular chamber 202 to act on annular piston 204 engaging the cylinder block. Alternatively, the vibrations may be applied mechanically to the end of the cylinder block. Sleeves 114 and 144 slidably engage the cylinder block to connect housing inlet and exhaust connections 110, 146 to corresponding cylinder block passages 116, 140. Reaction members 180A in the cylinders are connected to a common plate 156 biased away from pintle valve 90 by pistons 150, 151 subjected to supply and exhaust pressure, respectively. Alternatively, pistons 150, 151 may be replaced by springs. Bearing 160 may be of nylon. The pintle valve is hydraulically balanced by grooves (220), 222 and (224), 226 connected respectively to exhaust groove 106 and supply groove 108 in the valve, Fig.9 (not shown). Coolant is circulated through the motor between connections 214 and 216 by the centrifugal pumping action of passages 48 in the swash plate 40.

[Class 135] A locking device for gas taps comprises a portion adapted to embrace the thumb piece on the tap and a portion adapted to clip onto the body of the tap or the pipes leading thereto. In the form shown in the Figure, the part adapted to embrace the thumb piece comprises arcuate parallel arms bent or pinched adjacent their ends to' hold them in position. Additional pinches may be provided to bear on the sides of the thumb piece and the extreme ends of the arms may be' flared outwards to facilitate the passage of the thumb piece while the device is being positioned. To each of these arms is attached by riveting, soldering or other means a pair of depending arms A<1>, A<2> of springy metal which are curved at an intermediate point in their length to embrace the inlet and outlet branches of the cock. In a modification a single length of wire is bent upon itself to form two parallel limbs thus forming between them the openended recess to receive the thumb piece. These two limbs are next bent back at a point to make the recess of sufficient length and are then bent at right-angles to form a pair of arms. These arms are finally bent each to a somewhat horseshoe shape to grip firmly around the inlet and outlet branches.

Title: Welding process and apparatus
Inventor: FOULQUIER HENRI
IPC: B23K9/028
Filed: 1965-02-26
Abstract: 1,059,432. Welding by fusion. COMMISSARIAT A L'ENERGIE ATOMIQUE. Feb. 26, 1965 [March 5, 1964], No. 8440/65. Heading B3R. In welding a circular zone having a non- vertical axis, the welding unit is moved along a circle of approximately the same radius as the zone and displaced upwardly and a radial oscillating movement is superimposed. Thus in internally welding a sleeve (10) (Fig. 3a, not shown) to a coaxial horizontal pipe (12), the mating surfaces are machined to form a Y- sectioned annular groove centred on the pipe axis, and arc welding is carried out using a consumable electrode moved as set out above to produce an even smooth weld deposit. The welding machine comprises a rotatable tubular portion (B) insertable into the sleeve (10) and centred in the sleeve (10) by balls moved outwardly by rotation of a rod (40). After centring the portion (B), a mounting portion (A) carrying the portion (B) is bolted to the sleeve (10) and the portion (B) is axially adjusted by a rack. The welding head is mounted on a transverse pin on the end of the portion (B) and its radius of action is determined by sliding movement of the rod (40) which is lockable to the arm (41) (Fig. 6, not shown) of an adjustable eccentric (56) driven by a motor and mounted on a plate (46) slidably carried by the portion (B). The motor produces the rapid transverse oscillation of the welding head. Journalled in the plate (46) is a second adjustable eccentric (56<SP>1</SP>) the rod (41<SP>1</SP>) of which is connected to a rod (40<SP>1</SP>) engaging a nut (78) axially captive on the portion (B). Nut (78) provides for fine variation of the radius during welding. The second eccentric (56<SP>1</SP>) is connected to a gear fixed to the stationary portion (A) and rotates in synchronism with the portion (B) to move the welding unit on a mean path which is a circle displaced upwardly from the axis of the portion (B). An optical or a television system located within the portion (B) enables the weld to be observed.

Title: Improvements in or relating to telephone systems
IPC: H04Q3/00
Filed: 1930-03-15
Abstract: 350,576. Automatic exchange systems. AUTOMATIC TELEPHONE MANUFACTURING CO., Ltd., Strowger Works, GILLINGS, C., 28, Eldred Road, Mossley Hill, and TAYLOR, R., 30, Oulton Road, Wavertree, all in Liverpool. March 15, 1930, No. 8452. [Class 40 (iv).] In a system employing bi-directional callfinders of the type described in Specification 343,088, the finders are taken into use by a relay allotter so arranged that the finders are taken into use in turn. Two groups of finders are provided and should all the finders in one group be engaged when a call is originated, a free finder in the second group is seized. As described five finders and one set of control relays are provided in each group. When a call originates relay AA energizes completing circuits for slow relay KA and, if finder 5 was the last used, for relav 1CA (Fig. 2) in the first finder circuit (ka5, aa2, za2, 5ca3, 5cb5, 1ca3, 1cb5). Relay 1CA prepares a circuit for 1CB and, when KA pulls up, 1CB energizes in series with 1CA switching the selected finder to the common control unit. Relay FR energizes. The vertical magnet VM interacts with relay G to raise the finder to the required level after which the rotary magnet RM interacts with G moving the wipers to the calling line when either relay 1HA or 1HB energizes to switch the circuit through. This action is fully described in Specification 343,088. Relay FR releases breaking the circuit of KA, ensuring the release of KA even if AA has been operated by another caller. When AA operates on the next call relay 2CA is energized (1ca3, 1cb5, 2ca3, 2cb5) releasing relays 1CA and ICB and, when KA pulls up, 2CB energizes connecting up the second finder circuit. Other calls take the finders in sequence the relay operations being identical with those described. If a finder, for example the first should be engaged, either earth is connected over the release conductor (indicated as 1RT) or the off normal contacts 1N are operated. In either case when 21CA energizes, on AA operating, a circuit is completed from 1RT or 1N to energize 2CA and if the second finder is busy relay 3CA (not shown) pulls up, the sequence continuing until a disengaged finder is found. When KA energizes, the CB relay of the disengaged finder only pulls up, switching the circuit through. If all the finders in a group are engaged relay ZA (not shown), which is normally operated, releases connecting up the relay allotter of the second finder group. If all finders of both groups are busy the operation of AA is without effect. A system in which engaged finders are shorted in the chain start circuit by contacts of the switching relays is also described. Specification 293,294, [Class 40 (iv), Telephones &c.], also is referred to.

Filed: 1928-07-14
Abstract: 316,090. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). July 14, 1928. Divided on 309,842. Emulsions, making. - Emulsifying agents are made by converting quaternary ammonium bases, containing at least one aromatic substituent but no acid group capable of forming an inner salt, into their salts with cycloaliphatic or hydroaromatic acids or sulphonic acids or sulphuric esters possessing a pronounced wetting or emulsifying power. Such acids are naphthenic acids, aliphatic sulphonic acids, such as those described in Specifications 272,967 and 288,612, aromatic or hydroaromatic sulphonic acids, especially those containing alkyl, aralkyl, cycloalkyl, or aryl groups, with or without further substituents, whether in the nucleus or in the side chain, turkey red oils, sulphonation products of mineral or aliphatic tar oils, and the lignosulphonic acids contained in sulphite-cellulose waste liquor. Less than the equivalent quantities of the organic bases may be added to the acids, or a portion of the organic base may be replaced by an inorganic base, such as caustic soda or ammonia; mixtures of organic bases may also be used. In an example, the sodium salt of dibutylnaphalene sulphonic acid is treated with dimethylbmzylphenylammonium chloride. Trimethyl - (and triethyl) - phenylammonium hydroxide and trimethyl-alpha- (and #-) naphthylammonium hydroxide are also specified as ammonium bases, and the sodium salt of propylated naphthalene sulphonic acid may replace the sodium salt used in the example.

Title: Improvements in and relating to processes and apparatus for producing silica articles
IPC: C03B5/033
Filed: 1927-03-29
Abstract: 268,780. British Thomson-Houston Co., Ltd.,(Assignees of Walson, H. L.). April 1, 1926, [Convention date]. Forming silica glass articles.-Relates to the method of making rods or tubes of fused silica described in Specification 230,499, and consists in adapting the apparatus for producing larger articles such as cylinders having a diameter of sixteen inches or more. The furnace used for fusing the silica comprises a receptacle 17, of refractory material, containing a graphite pedestal 23 on which a core 21 is mounted. The plastic silica, when the drawing force is applied, flows from the fusion zone 24 over the core 21 towards an outlet shoot 25 and produces a hollow body 26. The shoot 25, which forms a shaping-die, is surmounted by a cylinder 27, preferably made of zirconium silicate, and both are supported by iron bars which rest on the edges of the receptacle 17. The silica is fused by three sets of resistors 32, 33, 34. The resistors 32, 33 are connected in parallel with terminals 35, and the lower resistor is connected to terminals 37 which enter the opposite wall of the furnace. The resistors 32, 33 are hexagonal in outline and surround the core 21 and the die 25. The resistor 34 is rectangular in outline and its function is to keep the silica around the core 21 thoroughlyÀ fused. The bait of the drawing apparatus comprises a wire 44 supported by other wires 45 which depend from a metal plate 46. The wires 45 are of tungsten or molybdenum and they pass through a graphite cover 51 and heat-insulating plate 52, 53. They may be enclosed in tubes of quartz or other refractory material. In operation, comminuted silica, such as sand, is filled into the container 17, and when sufficient is fused, the bait is withdrawn at the desired speed by means of a cable and draws out the fused silica as a cylinder 26, or in any other form determined by the shape of the die 25 and the core 21. The die 25 and cylinder 27 exclude unfused silica from the fused material which is withdrawn, and shields the emerging tube from heat radiated from the fusion zone. The bore or diameter of the article produced may be co.ntrolled by keeping the drawing-force constant and altering the viscosity of the fused mass by altering the heating-current passing through the resistors. Alternatively, the temperature of the fused mass can be kept constant and the amount of tractive force applied to the bait may be varied by a variable speed gear interposed between the driving motor and drum on which the cable is wound. A speedometer may be provided to indicate the speeds suitable for drawing tubes of different sizes The Specification as open to inspection under Sect. 91 (3) (a) describes a modified construction for drawing tubes or rods of small diameter, as described in the earlier Specification 230,499. This subject-matter does not appear in the Specification as accepted.

Title: Process for the manufacture of paperboard from straw with the simultaneous production of furfuraldehyde
IPC: D21C1/04
Filed: 1937-03-25
Abstract: Straw is treated at elevated temperature with dilute sulphuric acid, phosphoric acid, formic acid, acetic acid, or an aqueous solution of aluminium sulphate, so that not more than 60 per cent of the pentosans is removed either as such or in the form of furfuraldehyde, and the straw residue is then treated with calcium hydroxide.  The straw pulp produced can be converted into paperboard, while furfuraldehyde may be recovered from the acid solution by steam distillation.  In an example, rye straw is treated with 0,25 normal sulphuric acid for 1 1/2 hours at 100 DEG  C., then washed, and then treated with milk of lime for 30 minutes under 3 atmospheres pressure at about 140 DEG  C.  The straw pulp produced is ground and made into paperboard, while furfuraldehyde is recovered from the acid solution by heating to 140-160 DEG  C. and steam distilling.  According to the Provisional Specification, straw is treated at elevated temperature with dilute acids or aqueous solutions of acid substances, so that only a part of the pentosans is removed, and the straw residue is then treated with alkali-reacting agents.
