Title: Improvements in or relating to looms
IPC: D03C1/12
Filed: 1962-04-30
Abstract: 1,004,777. Loom dobbies. RUTI MACHINERY WORKS Ltd. April 30, 1962 [May 5, 1961], No. 16519/62. Heading D1E. In a positive single-lift open-shed dobby, the lack levers 17 are actuated by eccentric straps 20, the sheaves of the eccentrics being attached to sun wheels 22 around which planetary gears 28 are oscillated by a cam 41. Curved racks 43, 44 pivoted on a fixed shaft 45 can be brought selectively into mesh with the planetary gears to cause them to rotate the sun wheels from one dead centre position of the eccentrics to the other, thereby lowering or lifting the healds coupled to the corresponding jack levers. To control the racks, a shaft 56 carrying levers 48 is oscillated vertically by a cam 53. The shaft carries floating levers 48 which can depress the racks by means of compression springs 64. The racks are urged upwards by springs 46 so that, in the idle condition (shown for the left hand levers 49) oscillation of the shaft 56 mostly rocks the levers 49 without affecting the rocks 44. To operate a heald, a bellcrank lever 58 or 67, is turned by the pattern mechanism when the shaft 56 is at the top of its stroke, to bring its end 58a over the end 48a of a lever 48, thereby holding the end of the lever on a stop 57 to act as a fulcrum; descent of the shaft 56 then depresses the corresponding rack 46 into mesh with the planetary gear. In another embodiment, each jack is linked to two toothed segments serving as sun wheels, and a double-sided rack is situated between the planetary so that it can be brought into mesh with either of them or can be locked in a mid-position. At the end of a movement of the jack caused by the rack engaging one of the planetary gears, the rack is rocked, by spring-loaded connections with the jack, into mesh with the other planetary gear, unless arrested in its midposition by the pattern mechanism, in which case it does not operate the jack lever on the next cycle.

Filed: 1954-06-04
Abstract: 756,995. Switchgear structures. TELEMECANIQUE ELECTRIQUE. June 4, 1954 [June 8, 1953], No. 16639/54. Class 38(5) In a circuit-breaker having a withdrawable framework 1 and a fixed base 2, the base carries two closely-spaced, parallel rows of contacts 3, 4 for control circuits and the framework carries two sets of resilient fingers 10 cooperable with the contacts 3, 4, and, between each pair of fingers, a conducting bar 16 supported by a longitudinally movable rod 18 which is mechanically linked with a moving part of the circuitbreaker. The circuit-breaker is electromagnetically actuated, the movable blade 7 being secured to a contactor shaft 8 and having a restoring spring 9 and a lug 29 which is secured to shaft 28. The shaft 28 is connected to a crank lever 26 the end 26a of which abuts rod 18 so that when blade 7 is attracted, rod 18 is raised against the action of spring 20 to cause each bar 16 to interconnect its associated pair of fingers 10. The fingers 10 are of insulating material and have metallic caps on their exposed ends, and are urged outwardly by springs from their housings in an insulating plate 12 so that when framework 1 is withdrawn the insulating. portions of fingers 10 move into contact with the bars 16 thus breaking the control circuits before the fingers disengage the contacts 3, 4.

Title: Improvements in or relating to washing machines
IPC: D06F29/02
Filed: 1933-06-12
Abstract: 406,538. Washing-machines. BLOOM, H., and RYCKMAN, N. E., 77, Niagara Street, Hamilton, Ontario, Canada. June 12, 1933, No. 16797. [Class 138 (ii).] The frame 20 ofawashing-machinesupports a wash tub 27 and a tank 26, the latter 26 having a centrifugally operating perforated bowl 33 for drying purposes. The bowl 33 has a number of radial perforated blades 36 extending upwardly from the bottom, and mechanism is provided to cause the bowl 33 to oscillate when it is used as a washing bowl. The tank 26 is supported on rubber blocks 28 and has a discharge outlet which may be connected to the pump 86 driven by the motor 75. The wash tub 27 contains members 61 on the spindle 60 which is oscillated by the motor through the gearing shown in Fig. 5. The motor operates the worm gear 72, 71 and causes the eccentric 69 to reciprocate the rod 68 so that the segment gear 65 oscillates the pinion 62 and the spindle 60. The segment gear 65 is brought into engagement by means of the handle 82. The bottom 35 of the bowl 33 rests on a flange 32 on the shaft 31, and the central stud 34 with the radial blades 36 rises from the bottom. An annular guard 38 bridges the gap between the tank 26 and the bowl 33. The cover 39 of the tank 26 is connected by cam and rod mechanism to the rocker arm 53 which operates the clutch and brake 55, 56. When the cover is raised, the arm 53 forces the cone 56 against the fixed part 58 to brake the bowl 33, and when the cover is lowered the clutch cone 55 is raised to engage the clutch part 57. The bowl 33 is driven as a washer through the oscillating gear 77, 78, 79, or as a centrifugal drier through the spiral gear 99, according to the position of the handle 81. At starting the pump connections 93, 94 are connected to the hot and cold water supplies, and the pump passes water to the tub 27. The pump is cut off and the materials to be washed are inserted in the tub. After washing is effected the water is run off and the materials transferred to the bowl 33 for drying. Where the quantity to be washed is small, it is placed in the bowl 33 and the bowl is oscillated. The washing water is circulated by the pump through the connections 88, 89, 29 and after washing is completed, the handle 81 is operated so that the bowl rotates as a drier.

Title: Horizon sensor
IPC: G01S3/782
Filed: 1975-04-23
Abstract: 1477065 Horizon detector HUGHES AIRCRAFT CO 23 April 1975 [3 June 1974] 16837/75 Heading H4D An infra-red sensitive horizon detector has a pulse width discriminator 14, Fig. 1, to render it insensitive to large amplitude but small width pulses 22, Fig. 2 (i.e. not due to the Earth's disc (24)) and a gated AGC circuit to cause the amplitude of the pulses 24 at the input of a threshold circuit 10 to stay substantially constant from scan to scan. The gain controlled amplifier 8 has a high pass characteristic which removes any fluctuations in the Earth's pulse 24, and produces a partial differentiation to give output pulse 26, 28. These are then compared with a threshold E in comparator 10 to give output 30, 32. Pulse 30 is rejected (too short) by pulse width discriminator 14 which produces Earth scan indicative pulse 34. The output of amplifier 8 has 2E substracted from it at 12 and the peaks of the resultant signal are stored during the times of the pulses 30, 32, by means of gated peak detector 16 to give signal 36. A gate 18 enabled by pulse 34 selects the part of signal 36 due to the Earth scan (which part should have a zero voltage level), and passes said part for integration over several scans at 20 and production of the gain control signal for the amplifier 8. A detailed practical example of the arrangement of Fig. 1 is shown and described, Fig. 3 (not shown).

Title: Improvements in or relating to lubricating oils
Filed: 1935-06-12
Abstract: A dehydration condensation polymer of octadecanediol or a condensation product of chlorinated paraffin wax with a polycyclic phenol ether is used as a pour-point depresser of lubricating oils. Ethers specified are: the methyl, ethyl, propyl, butyl, amyl, lauryl, and phenyl ethers of a - or b -naphthol; aliphatic or aromatic ethers of polyhydroxy-naphthalenes, di-naphthol, hydroxy-anthracenes, or of mono- or poly-hydroxy - diphenyls; diphenyl oxide.  The depressants may be refined by extraction, e.g. with ethylene dichloride, acetone, or ethylmethyl-ketone. In examples of their preparation: (1) the crude product containing octadecanediol obtained by hydrogenating castor oil is heated with sodium hydroxide at 260--275 DEG  C. and 13 mm. pressure; (2) a solution of the ethyl ether of b -naphthol in cyclohexane is treated with aluminium chloride, and after cooling to 35 DEG  C. chlorinated paraffin wax containing 12 per cent of chlorine is added; after raising the temperature to 80--85 DEG  C., the product is thinned by cyclohexane, filtered, and freed from solvent by vacuum distillation.ALSO:The pour point of lubricating-oil containing wax is lowered by adding a small quantity e.g. 0,25--2,0 per cent of a dehydration condensation polymer of octadecanediol, or a condensation product of chlorinated paraffin wax with a polycyclic phenol ether.  Ethers specified are: the methyl, ethyl, propyl, butyl, amyl, lauryl, and phenyl ethers of a  or b  naphthol; aliphatic or aromatic ethers of polyhydroxy-naphthalenes, di-naphthol, hydroxy-anthracenes, or of mono- or polyhydroxy - diphenyls; diphenyl oxide.  The crude depressants may be used directly, or the active material may be extracted therefrom by solvents, e.g. ethylene dichloride, acetone, ethyl-methyl - ketone. Examples: (1) 10 gm. of aluminium chloride is added to a solution of 13,5 gm. of the ethyl ether of b -naphthol in cyclohexane, and after cooling the mass to 35 DEG  C. 90 gm. of chlorinated paraffin wax containing 12 per cent of chlorine is stirred in for 23 hr.; the temperature is raised to 80--85 DEG  C., for 30 min., and the product thinned by cyclohexane, filtered, and freed from solvent by vacuum distillation.  1,0 per cent of the depressant reduces the pourpoint of an engine oil containing paraffin and petrolatum from 25 to -5 DEG F.; (2) 50 gm. of the crude products containing octadecanediol obtained by hydrogenating castor oil are heated with 1,25 gm. of sodium hydroxide for 63,5 hr. at 260--275 DEG  C., and 13 mm. pressure. 0,5 per cent of the colourless jelly produced reduced the pour point of the engine oil from 25 to 0 DEG  F.
