Abstract: 750,478. Handle-bar control mechanism. EASTON, H., and FARGION, B. R. Nov. 6, 1953 [Nov. 6, 1952], No. 28007/52. Class 136 (1). A control device in the form of a twist grip has a cable drum formed by flanges 2, 3 on a tube 1, the drum being adapted to receive at least two.Bowden cables 16 the nipples 18 of which rest against the ends of the flanges 2, 3 which extend over only half the circumference of the tube 1. A split housing 5, 6 surrounds the cable drum. The maximum tension applicable to each cable is defined by a loose stop member 20 contained in a channel 8 in the member 6. The nipples 18 are of such a size that they can move in the member 6 but not in the member 5. When the grip is twisted either way, the trailing end of the flanges 2, 3 passes into the member 5 and the nipple 18 rests against the edge of the member 5. Further movement is possible until the nipple at the leading edge of the flanges pushes the member 20 into contact with the aforementioned nipple. The grip is retained in any desired rotational position by a ball 10 urged by a spring 11 into frictional engagement with the flange 3. The control is held in the clutch fully withdrawn position by the ball 10 entering a hole 21 in the flange 3. The ball and spring may be replaced by a ratchet device. As shown in Fig. 4, the cable may be directly adjusted by a knurled nut 23 which engages a threaded member 24. A grub screw 26 engages a longitudinal slot 25 in the member 24. Specification 750,479 is referred to.

Abstract: 469,091. Colour photography. COLORAY CORPORATION. Oct. 11, 1935, No. 28122. Void. Convention date, Oct. 23, 1934. [Class 98 (ii)] Organic fibrous material such as artificial silk, silk, wool, or cotton is treated with an organic solution of a salt of a radioactive metal, such as uranium, thorium or radium, and a salt of a non-radioactive metal, and is treated by ultra-violet light having wavelengths from 1700-3200 A.U. to obtain a colour change. In colour photography, cellulose, celluloid or viscose bases are treated with the following sensitizing solutions. A solution for producing a red colour comprises uranium nitrate, ferric ammonium oxalate, citric acid, lactic acid, glycerine, ethyl alcohol, and alloxan. A solution for producing a yellow colour comprises uranium nitrate, ferric ammonium citrate, citric acid, lactic acid, glycerine, ethyl alcohol, and silver lactate or nitrate. A solution for producing a blue colour comprises potassium ferrocyanide or ferricyanide, uranium nitrate, lactic acid, glycerine, ethyl alcohol, and ferric ammonium citrate or oxalate. The colour may be produced on the surface or in the body of the base. Three colour component negatives are printed by light of wavelength below 4000 A.U., on to the three elements, which are then washed, dried and superimposed. The process may be applied to two-colour photography. The material is insensitive to daylight. Gold and platinum may replace the silver, cobalt or nickel wholly or in part the iron, and sodium or lithium the potassium. Salts of calcium, barium, strontium manganese, chromium and magnesium may be added. The alloxan may be replaced by a vanadium salt or copper sulphate. The metals may be employed as nitrates, chlorides, oxalates, lactates or sulphates, or in colloidal form. Silver, tin, copper, zinc and mercury may be made into an amalgam, and uranium or uranium nitrate and lactic acid added, and the mixture used as sensitive material. Silver lactate may be replaced by silver carbonate and lactic acid, or silver nitrate, sodium carbonate and lactic acid. Acids used in the preparation of the sensitive materials may be also glycollic, malic, tartaric or hydrochloric acids. The ultra-violet ray source may be a quartz mercury vapour lamp or a quartz lamp containing mercury vapour, helium, and argon.
Patent GB-608624-A (GB)
Title: Improvements in or relating to joints in thermo-plastic materials
IPC: B29C65/20
Filed: 1945-10-25
Abstract: 608,624. Piecing threads. STANDARD TELEPHONES & CABLES, Ltd., (trading as STANELCO PRODUCTS), and BISHOP, H. S. Oct. 25, 1945, No. 28207. [Class 120(iii)] [Also in Groups VIII and XXVIII] A device for joining the ends of threads of thermosplastic material comprises a first jig having two jig-clamps adapted to hold the two thread ends to be joined and controllably adjustable relative to one another to hold the ends in slightly spaced abutment while heat is applied to soften them, and to press the heat-softened ends together to form a joint, a second jig comprising a heating device, and guiding means to locate the jig-clamps relative to the heating device when the two jigs are assembled together. As shown, Fig. 1, the first jig comprises metal blocks 1, 3 which are adjustably spaced, block 3 being slidable on guide rods 2 against the action of springs 4 by a hand wheel 9 integral with a sleeve-nut 10 screwed onto a threaded rod 6. Movement of block 3 is limited in each direction to one turn of hand wheel 9, by stop nuts 7. 8. The threads to be joined are located in V-grooves 12 in transverse guide blocks 11 secured to blocks 1, 3, and are held in place by clamping plates 14 which pivot at 15 and are tightened down by nuts 21 screwing on studs 17 and provided with washers 20 and compression springs 19. The ends of the threads are cut off square, and each thread 25 is then secured in the appropriate V-groove 12 so that the ends just abut centrally in a hole formed by two semi-circular cuts 13 in the guides 11, the latter being separated by an amount corresponding, to half a turn of wheel 9 (see (a), Fig. 6). Guides 11 are then opened to their full separation so as to provide a small gap between the thread ends in which heated air can circulate (b), Fig. 6). For the actual jointing, the threadmounting is inverted and located on a heating jig, Fig. 9, comprising two plates 26. 36 of heat-resisting insulating material such as ceramic bolted to a housing for a transformer which supplies low voltage power to an electric heating element 28 of coiled resistance wire. The nut and bolt assemblies 17-21 fit into holes 34 in plates 26, 36, locating the thread-mounting jig so that the thread ends are positioned over the heating element 28. Current is switched on, and when the thread ends are soft, as judged by a thin wisp of smoke from the plastic material, wheel 9 is given a complete turn to drive the thread ends together (see Fig. 6(c) ), when the current is immediately switched off. Blocks 11 and clamping plates 14 are formed of good heatconducting metals, or may alternatively be of a non-conducting heat-insulating refractory material. Heating may alternatively be provided by radiation from above the joint, or by a jet of hot air or gas.

Title: Process for the electrolytic recovery of metals
IPC: C22B3/10
Filed: 1973-06-14
Abstract: 1427228 Electro-winning of metals CYPRUS METALLURGICAL PROCESSES CORP 14 June 1973 28253/73 Heading C7B Metal, e.g. Cu, Ni, Ag, Zn, Cd, Hg or Pb is recovered from the metal sulphide by leaching the metal sulphide using a solution containing ferric ions, e.g. as ferric chloride, to form a solution containing ions of the metal to be recovered, and ferrous ions but substantially no ferric ions, and by passing the solution so formed to the cathode compartment of a divided cell and electrolyzing the solution to deposit the metal to be recovered at the cathode whilst continuously flowing the catholyte through the diaphragm, thereby preventing ferric ions formed at the anode from contacting the cathode, and removing anolyte from the anode component of the cell. Electrolysis may be preceded by separating the sulphur produced by leaching from the leach solution. The cathode used is preferably formed of the metal to be recovered; and the anode may be of graphite or of precious metal oxide-coated titanium. The diaphragm may be of woven polypropylene cloth.

Title: Fluid-pressure-operable clamping and like devices
Inventor: FLINT JOHN CHRISTOPHER EGLENGT
IPC: B23Q3/08
Filed: 1965-07-03
Abstract: 1,090,577. Machine tool details. DOWTY TECHNICAL DEVELOPMENTS Ltd. June 24, 1966 [July 3, 1965], No. 28268/65. Heading B3B. [Also in Division F1] Workpieces 12, 13 are clamped on a worktable 14 by a plate 17 which carries a fluid pressure means 11 having a piston rod 20 connected to a rod 21, which is secured to the table. Means 11 comprises a cylinder 16, a first piston 28 having a hollow piston rod 29, a second piston 31 having a hollow piston rod 20, and a ball valve 41. Piston 28 has a cup seal 46 which in its upper position engages a frusto-conical projection 48 formed on an end cap 24. In operation, with piston 28 in the Fig. 2 position, and ball 41 unseated by a rod 27, fluid under pressure passes through a line 15 into a chamber 49, through piston rod 29, into the interior 34 of piston rod 20 and through a part 35. Piston 31 moves upwardly a certain amount, thus providing a light clamping of the workpieces. The pressure builds up in chamber 49, piston 28 moves downwardly, and ball valve 41 closes thus trapping the fluid in passages 39, 34, 36. Seal 46, 48 is broken so that the whole of the face area 44 of piston 28 is subjected to pressure, and piston 28 moves against springs 37, 38 more rapidly, so that when rod 20 penetrates interior 34 of rod 20, the pressure of the trapped fuel is intensified. Piston 31 moves upwardly and the workpieces are more securely clamped. The fluid may be liquid supplied from a reservoir which is pressurized by compressed air, or the fluid may be compressed air.

Title: Improvements in direct cranking engine starters and the like
IPC: F02N15/06
Filed: 1947-10-22
Abstract: 636,927. Clutches. BENDIX AVIATION CORPORATION. Oct. 22, 1947, No. 28280. Convention date Nov. 12, 1946. [Class 80 (ii)] [Also in Group XXVII] In apparatus, which may be an engine starter, comprising a housing member 82 having an opening in which a rotatable member 12, for example a jaw member, is axially movable into engagement with a load element 14 to be rotated, such as a part of the engine to be started, and an axially stationary rotor 24, which may be a nut, operatively connected with the rotatable member 12 to effect axial and rotative movements thereof, there is provided means 18 for both fluid sealing the opening between the housing member 82 and the rotor 24 and to hold the rotatable member 12 frictionally against rotation during its axial engaging movement with the load element 14. A barrel 46, which is driven through speed-reducing gearing and sun-and-planet gearing, effects rotation of the nut 24 by means of an adjustable friction-disc coupling 72. Rotation of the nut 24 causes axial movement of a screw shaft 22 that has a splined connection 20 with the member 12 and so tends to compress a spring 30 which causes the member 12 to move into engagement with the element 14. Upon abutment of shoulders 26 and 28, on the screw shaft 22 and nut 24, respectively, the latter then causes rotation of the screw shaft 22 and member 12 to effect cranking of the engine. The spring 30 is housed between a collar on the screw shaft 22 and the rear face of a mesh rod 32, the latter being bolted to the member 12, whilst a sealing washer 36 is interposed between the rear face of the member 12 and front face of the mesh rod 32. The friction and oil seal device 18, which is made of rubber or material such as neoprene, is vulcanized to a part of the starter housing, the inner part of the device being left in a resilient condition. The device 18 has a stepped inner periphery, the part 100, of larger diameter, being held in position around an extension of the nut 24 by a garter spring 106, whilst the part 98 of smaller diameter is maintained in contact with the outer periphery of the member 12 by another garter spring 104. The inner periphery of part 98 incorporates a number of annular grooves 102, which serve to wipe oil off the member 12. In a modification, the two parts 98 and 100 are separately constructed and attached to the starter casing. In another modification, the part 98 is replaced by a split friction ring, which is made of such material as phosphor bronze.

IPC: H02H7/22
Filed: 1925-11-12
Abstract: 243,703. Rheinisch - Westfalisches Elektricitõtswerk Akt.-Ges. Nov. 29, 1924, [Convention date]. Cut-out arrangements, particularly for household distribution plants of the three-phase fourwire type in which the neutral h of the threephase e, f, g is insulated, make use of a four-pole switch a, enclosed in a metal casing t, both as a service supply switch and as a safety cut-out in the event of fault. The metal casing o of the household supply is in metallic connection with the casings of all electric apparatus on the circuit, but is insulated from the main switch casing by the insulation u. Overload tripping coils b, c, d for the breaker are located in each phase, and, in addition, a tripping coil r is connected between the metal casing and the neutral wire with a resistance s, equal to the resistance of the coil r, in series with it. The arrangement affords protection against a short-circuit between the neutral and a phase conductor (through the action of one of the trip coils b, c, d and the coil r), earth connection of a phase, and interruption of the neutral (externally or internally of the household supply).

Title: Improvements in and relating to noise suppression circuits for radio receivers
IPC: H03G3/26
Filed: 1949-11-08
Abstract: 659,723. Radio receiving circuits. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 8, 1949, No. 28601. Convention date, Nov. 12, 1948. [Class 40 (v)] In a frequency-modulation receiver muting is controlled by a "squelch" valve connected to an off-tune discriminator circuit, and which becomes non-conductive in the presence of a signal, thereby removing a blocking bias from an audio-frequency stage of the receiver. The output of the signal discriminator 11 is applied over a blocking condenser 15 to an amplifier 17 which is biassed to cut-off, in the absence of a signal carrier, by means of a network comprising resistances 19, 20, 24 and the anode path of a valve 23. An auxiliary discriminator 14 is adjusted off-tune so that in the presence of the carrier wave of the desired signal a D.C. output of negative sign is produced, which is applied to the grid of the valve 23 and causes it to become non-conductive, thereby removing the muting bias on the valve 17. The auxiliary discriminator 14 may alternatively be omitted, the grid of the valve 23 being fed over a lowpass filter from the signal discriminator 11, which is adjusted off-tune in the requisite manner.

Title: Transmission clutch
IPC: F16D43/18
Filed: 1932-10-13
Abstract: 392,819. Friction clutches. HADDAN, R., 31, Bedford Street, Strand, London.- (Western States Machine Co. ; Salt Lake City, Utah, U.S.A.) Oct. 13, 1932, No. 28610. [Class 80 (ii).] A friction clutch has manually-controllable centrifugally-actuated clutch shoes 12, fulcrumed on levers 8, pivoted, at their forward ends, to the arms 7 of a spider 6 fast on the drive shaft 5. The shoes 12 are forced by centrifugal action against the rim 2 of a driven pulley 1, and, in order that the rear part thereof may engage the rim 2 before the front part thereof, each shoe is overbalanced at the rear end such as by a spring 14 pressing thereagainst. The effect of centrifugal force may be varied by the addition of weights 21. The clutch shoes may be retracted by moving a sleeve 19 into the position shown in Fig. 2. The sleeve is connected to the free ends 8e of the levers 8 by toggles 18, adjustable links 16, and levers 17 pivoted to the spider 6. The clutch is put in operation by moving the sleeve 19 to the right, Fig. 2, and, if the shoes 12 are worn, this is indicated by the sleeve 19 abutting a sleeve 22. In a modification, applicable to a clutch connecting two aligned shafts, the clutch shoes 12 are brought out of action by the centrifugal effect of weights slidable on the longer arm of the lever 17. The weights are held, by spring action, normally in a neutral position so that each weight coincides with the pivotal axis of a lever 17, and they are moved manually to the right, Fig. 2, to counteract gradually the centrifugal force of shoes 12.

Abstract: 639,957. Bearings; lubricators. KNITTING MACHINES CORPORATION. Oct. 27, 1947, No. 28624. Convention date, Nov. 6, 1946. [Classes 12 (i) and 12 (iii)] The upper and lower anti-friction, e.g. ball, bearings of a high-speed vertical spindle 14 as used in yarn manufacture are mist lubricated from a reservoir 12 through a small diameter smooth-walled tube 54, spindle cross-bore 56 and tubes 58, 60 bound to the spindle 14 by a spring holder 66, the latter, tubes having outwardly turned lubricant-directing nozzles, and in which the lubricant flow is effected by centrifugal force and by capillary action. Loss of lubricant from the top bearing is prevented by a slinger shoulder 82 on a sleeve 25, which throws the excess lubricant through apertures 92 in a lubricant guard 80 into channels 94 in a stationary housing 10 whence it returns to the reservoir via further channels 96, both of which byepass the bearings. A pair of dished sealing baffles 76, 78 pressed in the housing 10 also prevent loss of oil and the entry of foreign matter, e.g. lint, which sealing is further assisted by a guard 26 attached to the annular sleeve 25, and having but small clearance from the housing 10, and by which the spindle is driven from a belt (not shown). Flow control of the turbulent lubricant is effected by corrugations 68 and a cup 70 in the reservoir 12, the latter being sealed by a cork or similar washer 50 engaged by serrated edges of its adjacent members. A key 100 engaging a keyway 102 in the outer race ring 24 of the lower bearing permits axial sliding to compensate for expansion and contraction.
