IPC: B41J19/18
Abstract: 105,865. James, R. W., (Remington Type writer Co.). Oct. 21, 1916. Letter-spacing mechanism; space-key actions.- (1) In machines in which a universal bar is actuated by type-levers 10 during the latter part of the printing-stroke, a 'variable-leverage device of the following described character is provided for starting the dog rocker slowly and increasing the speed towards the end of the printing stroke. The universal bail 16 actuates a lever 26 connected to the rocker 9 by a link 30 which is formed with an arm 31 engaging the lever and an arm 29 provided with a slot 28 engaging a pin 27 on the lever, the pin being normally separated from the end of the slot. The link is actuated initially at a slow speed by the arm 31 and is actuated at an increased speed during the rest of the stroke by the pin engaging the end of the slot.. The lever 26 is secured to a rock-shaft 22 provided with arms pivoted to arms 19 at the sides of the universal bar. The universal bail is supported at the middle by a pin 18 entering the segment 12. The link 30 is pivoted to a lateral pin 34 on t herocker. (2) The space-bar actuates the rocker through connexions which enable the space-bar to be actuated independently of the universal bail and vice versa. As shown, a lever 47, Fig. 4, pivoted at 48 and connected by a link 43 to the space-bar lever 38, is provided with a finger 55 and an incline 57 engaging a lateral pin 58 on the rocker. At each operation of the space-bar, the incline 57 operates the rocker, the slot 28 preventing the movement from being transmitted to the universal bail. The parts 55, 57 are formed on a plate 51 adjustably secured to the lever 47 by screws 53 passing through a slot 52. The link 43 passes through a cross-bar 41 on the space-bar levers and is threaded to receive an adjusting-nut 44. (3). The rocker consists of a plate or drop forging 59, Fig. 1, formed with a fast dog 8 and with trunnions 61 mounted on pivots 71 on a bracket 66. The movements of the rocker are limited by the engagement of stopscrews 64, 68 with stop-screws 65, 69. A returning-spring is connected to a screw 81 on one of the trunnions. The loose dog 7 is formed with a hub 77 mounted on one end of a headed pin 78 which passes through the rocker and a collar 78 thereon and is secured by a screw. The loose dog is moved against a stop by a spring 84. The connecting-pins 34, 58 are secured to an arm 88 mounted on a clamp-screw 89 on the rocker and provided with an adjusting-screw 91 which is threaded in the rocker and passes through a spring 93 arranged between the rocker and the arm. On loosening the screw 89, the arm can be adjusted forwards or backwards by turning the screw 91. The thrust of the link 30 or the lever 47 is received by the head of the screw 91.

Title: Improvements in or relating to photographic developing processes and apparatus
IPC: G03D7/00
Filed: 1929-04-05
Abstract: 331,823. Fuke, F. C., and Ozalid Co., Ltd. April 5, 1929. Developing.- In a process for the development' of prints, especially diazotype prints, by means of an alkaline vapour, such as ammonia gas, the prints are subjected before, during, or after exposure to the vapour, to the action of steam in quantity greater than would be obtained by the evaporation of the alkaline liquid used in development. In a preferred form of carrying out the invention, the prints are developed in a closed chamber into which jets of ammonia gas and steam are blown. The developing chamber 21 forms the upper half of the apparatus, and is constructed with sloping sides 23 - - 26 to carry off the products of condensation through a gully 56. The prints are fed into the chamber by a roller 30, and conveyed round the drum 27 by a continuous band 29 preferably divided into a series of narrow strips, a mixture of steam and ammonia gas being blown into the band in contact with the drum from a tube 70. The prints are finally ejected into the lower half 16 of the apparatus where they are subjected to a current of air circulated by the fan 90. Packing strips in contact with the drum 27 prevent the escape of gas at the points of entry and exit of the prints. The supply of ammonia gas and steam is generated in an electric water heater, which may be provided with a float chamber to maintain a constant level of liquid. In a modification, the steam and ammonia gas are evaporated in separate vessels.

Abstract: 705,234. Preventing corrosion. STANDARD OIL DEVELOPMENT CO. April 28, 1952, No. 10645/52. Class 123(1) Corrosion in the vapour space of a vessel containing a liquid which evolves acidic vapours, e.g. crude petroleum oil, is minimized by introducing into the vapour space ammonia in an amount substantially less than that required completely to neutralize the vapours, e.g. from 3 per cent to 20 per cent of the required amount. This is equivalent to maintaining in the vapour space a concentration of ammonia equal to 0.1 per cent to 0.8 per cent of the volume of the vapour space. The ammonia may be introduced through a pipe terminating in the centre of the top of the vapour space.

Filed: 1936-04-14
Abstract: 469,149. Aeroplane wing - flaps. PHILLIPS & POWIS AIRCRAFT, Ltd., and MILES, F. G. April 14, 1936, No. 10754. [Class 4] In an aeroplane having wing flaps divided into at least two sections of which one is a servo section moving to operative position in an opposite sense to the remainder, the servo section is so connected to the main section as not to become operative until after operative movement of the main section to such an opening that servo assistance becomes desirable. As applied to wing flaps such as described in Specification 443,651, main flap portions A and a servo flap portion B, Fig. 1, are coaxially mounted or substantially so on wings and fuselage respectively. A shaft E in the fuselage carries a gear-wheel F on each side of the fuselage meshing with quadrants G on the inner ends of torque tubes H in the wings, the latter carrying levers I connected by links J to flap parts A. Shaft E carries a lever L connected by link K to flap B. The arrangement is such that rotation of shaft E adjusts flap parts A through some 20‹ before any effective movement of flap part B takes place. The leading edge of flap B may be masked sufficiently to cover any movement thereof during the initial movement of flap parts A. The full adjustment may be such as to bring parts A and B into parallel planes slightly inclined forwardly. The flaps may be operated by suction means operating against the tension of a helical return spring and controlled by a hand lever working in a gate having positions corresponding to " shut," " partially open," and " fully open." As shown in Fig. 4, a piston rod U is connected to a lever O pivoted at N to a lever carried by shaft E. Lever O is adapted to bear by a roller P on a stop Q which is withdrawn on the pilot moving the hand control from the " partially open " to " fully open " positions. Stop Q is avoided on the return of lever M by movement of lever O about its pivot N.

Abstract: 732,973. Impregnated electric insulation. BRITISH INSULATED CALLENDER'S CABLES, Ltd. July 30, 1953 [April 30, 1952], No. 10874/52. Class 140. The dielectric or insulation of an electric cable comprises paper impregnated with a mineral oil imbibed or absorbed by the product obtained by subjecting a hydrocarbon oil or a polymerized aliphatic hydrocarbon to radio-active irradiation in such a way that carbon-to-carbon cross-linking takes place, whereby the tendency of oil to drain from the composite dielectric is reduced. The polymerized aliphatic hydrocarbon may be polyethylene, polyisoprene, polybutadiene, polymerised 2: 3-dimethyl butadiene, or natural rubber. The irradiation may consist of slow neutrons associated with fast neutrons and gamma rays as produced in an atomic pile, or it may be produced from a gamma ray source or an atomic or sub-atomic particle accelerator. The imbibing or absorbing material may be added in or on the paper or in the oil, e.g. it may be added as an emulsion or dispersion to paper pulp, a coating on paper strips, or incorporated in the oil as a powder. In an example paper that has been impregnated with a solution of polythene in xylene or made from a pulp containing dispersed polythene is subjected to irradiation in an atomic pile until 0.18 per cent of the carbon atoms are crosslinked. A conductor is insulated by lapping with a number of layers of treated paper, is immersed in mineral oil, and is finally covered with a metallic sheath and, if desired, armouring. Alternatively, the conductor may be axially rotated in a bath of mineral oil whilst paper tapes are applied, the paper having been preimpregnated with mineral oil to cause the irradiated polythene to swell before lapping is commenced.
