Title: Improvements in or relating to printing machines
IPC: B41F33/10
Filed: 1936-11-18
Abstract: 485,379. Printing-machines. TIMSON, E. A. Nov. 18, 1936, No. 31584. [Class 100 (ii)] Inking-apparatus.-In a printing-machine an ink feeding roller is adapted to be moved into and out of contact with the last ink distributing drum or roller of an inking-unit including two or more such distributing drums when a cylinder, e.g. an impression cylinder, is tripped, the machine including, in association with the cylinder or the cylinder trip mechanism and the ink feeding roller to be moved, intermediate connections arranged so that when the cylinder is tripped the roller is thrown-off, and when the cylinder is restored to its normal position the roller is rendered operative again. As shown, an impression cylinder 1 has associated therewith two plate cylinders 2, 3, and is adapted to be tripped. For inking each of the plate cylinders there is provided a pair of identical inking-units A, B. The unit A comprises a pair of rollers 5 for feeding ink to the last distributing-drum 6. The rollers 5 are adapted to be moved towards and away from the drum 6 by toggle levers 8 actuated by a link 10. The link 10 is connected to an arm 11 pivoted at 12 and rigidly connected with another arm 13, the free end of which engages in a slot 28 in a link 14. The link 14 is connected through a pivoted coupling 15 to one end of a link 16 which is associated with the trip mechanism of the impression cylinder 1. A spring 17 is secured at one end to the link 14 and at the other end to the free end of the lever 13. The slot 28 in the link 14 is to enable ink to be fed to the final distributing-drum 6 while the impression cylinder remains tripped, since the link 10 can be operated manually, independently of the remainder of the connections. In the inking-unit B the toggle levers are operated from the trip mechanism of the cylinder 1 by means of a link 26 connected to a pivoted arm which is rigidly connected to a further arm engaging in a slot in a link. This link is connected to a pivoted arm secured to a further arm connected to a link which actuates the toggle levers. Further mechanism may be embodied in the machine whereby automatically on the tripping and restoring of the cylinder the rotation of a roller or rollers may be stopped and started respectively. The roller concerned may be a duct roller, and driving- mechanism of the character described in Specification 472,236 may be employed. The spindle of such a duct roller has secured thereto a circular collar having a spring-pressed pawl normally projecting therefrom. A gear-wheel, continuously-driven, and freely mounted on the spindle has a recessed boss extending partly over the collar, and has a notch on the inside forming a driving shoulder which is engaged by the pawl. The pawl can be held out of engagement with the notch by means of a pivoted lever which is moved into the path of the pawl by an arm actuated from the trip mechanism of the cylinder 1.

Title: Improvements in and relating to the control of aircraft
IPC: B64C13/00
Filed: 1920-11-11
Abstract: 175,378. Scarff, F. W. Nov. 11, 1920. Steering and balancing; propelling.-A fluid-pressure system for assisting the pilot of an aircraft to move his controls has its working pressure controlled by the speed of the aircraft, so that the higher the speed the greater is the pressure available. The pressure system comprises a rotary pump 2 driven from the engine or by a propeller 4 arranged at the rear of a streamline casing 1 placed clear of the slipstream from the aircraft propeller. The pump 2 may be of the. cog-wheel type; it pumps oil through an inlet 5 and delivers it into a, passage 6 in communication with a relief-valve chamber 7. Ports 8 in the valve chamber are controlled by a piston 9 on a plunger 10 which moves in the cylindrical guides shown, one end of the plunger being subjected to the pressure in the passage 6 through a port 12 and the other end being open through a port 13 to the pressure in the casing 1, which serves as an oil-reservoir. The plunger 10 is connected by a spindle 14 to a collar 17, which engages pins 18 on levers 19 loosely pivoted at their outer ends to an axially movable plate 22, so that the wind pressure on the plate 22 acts on the plunger 10 in opposition to the fluid pressure through the port 12 and the amount by which the ports 8 are opened to exhaust, and consequently the pressure in the passage 6, depends upon the wind pressure on the plate 22. The plate 22 has a lip 29 so that the passage of air past it produces suction within the space enclosed by the plate. The plate is guided by a spider 26 sliding on a guide 27 and by a ballheaded pin 23 working in an axially bored member 25. Alternatively, a Pitot or Venturi tube may control the relief valve. The passage 6 communicates with the upper end of a cylinder 33, Fig. 3, having a piston 34 connected to a U- shaped member 36 provided with a spindle 37 on which are mounted rollers 38 working between guides 30. A transverse plate 39 on the member 36 acts upon a roller 40 carried by a crank 41 on a shaft 42, which has a drum 43 connected by cords 44 to the control surface or engine throttle and by cords 45 to the pilot's control. When the control is in its normal position, the crank 41 is at the dead-centre, but as it moves the pressure of the bar 39 has an increasing moment. The bar 39 may be shaped to suit the characteristics of the control to be operated, and may be shaped at the centre to give neutral equilibrium over a small range. A by-pass under the control of the pilot may be provided to throw the apparatus out of action. A trunnioned cylinder having a slotted plunger engaging a crank pin may be used instead of the cylinder shown.

Title: Process for purifying alkaline earth metal hydrides
IPC: C01B6/04
Filed: 1956-10-19
Abstract: An alkaline earth metal hydride, e.g. calcium hydride, is purified by successively heating equal portions of the hydride in a single vessel under such conditions that hydrogen is evolved from each portion and is mixed with alkaline earth metal vapour which is evolved from the preceding portion in substantially stoichiometric proportions, and condensing the hydride from said mixture.  Hydrogen may be finally added to combine with the metal evolved from the last portion. Hydrogen may also be passed through the hydride being decomposed. The portions may be added in succession to the decomposition vessel, or the portions may be present in a single body of the hydride and a decomposition zone allowed to progress discontinuously or continuously through the body.  In the latter case a cylindrical vessel having a plurality of external electrical heating rings may be employed. Alternatively the hydride may be passed continuously through a furnace.  Using an electrically-heated metal resistance wire for heating the decomposition vessel a temperature of 900 DEG C. may be attained, with which may be used a pressure of 0.1 mm. of mercury; using induction heating a temperature of 1200 DEG  C. may be attained, with which may be used a pressure of 100 mm. of mercury; using radiation heating, electrical resistance heating or induction heating in a carbon apparatus a temperature of 1800 DEG  C. may be attained, with which may be used atmospheric pressure.  The hydride may be condensed in less than 0.01 sec.  A mechanically-movable condensation surface which is freed from condensate by a stripper when the layer of condensate has reached 3 mm. may be used. Specification 803,767, [Group II], is referred to.

Abstract: 722,085. Transformers. WESTERN ELECTRIC CO., Ltd. Dec. 17, 1952 [Dec. 22, 1951], No. 31983/52. Class 38 (2). [Also in Groups XXXVI and XXXVIII] A high-frequency recording and reproducing head comprises a core 2 of magnetic material such as ferrite, bearing a first winding 4 comprising one or several turns short-circuited by a filament 6 which extends across the outer surface of the core and is flush therewith, and a second winding 8 comprising many turns with ends 10, 12 for connection to the associated equipment. The filament 6, which should lie in a plane parallel to the surface of the record cylinder or other member, and normal to the direction of relative motion between it and the record member carries current which produces or is produced by the record member flux, the two windings forming a transformer for connecting suitably the filament to the associated equipment. The filament should be very narrow, but the first winding turn or turns should have a width equal to one.tenth of the average length of the magnetic path in the core. To make this winding the core may be coated thinly with silver on which copper is deposited, the coating being masked, e.g. with nitrocellulose lacquer, to leave exposed the final path of the winding, which is built up by plating with copper or silver. The lacquer is dissolved away, e.g. with acetone and the core etched until the surfaces previously masked are free of metal. The filament 6 is formed in a groove. The second winding may be of enamel-covered wire and may be wound over the first winding if this comprises several turns as shown in Fig. 4. The core 4 may be annular, bar-shaped, Fig. 6 (not shown), rectangular, Fig. 8 (not shown), or triangular, Fig. 10 (not shown).
