Title: Toy rifle
IPC: F41C3/08
Filed: 1957-01-22
Abstract: 820,718. Toy rifles. HUBLEY MANUFACTURING CO. Jan. 22, 1957 [Aug. 1, 1956], No. 2261/57. Class 132(3) A cap detonating toy rifle comprises a slide resiliently urged towards a fixed anvil, a hammer spring-loaded towards the slide, and means to enable the hammer to be brought to a cocked position away from the slide. On its release from the cocked position, the hammer strikes the slide and thus causes a cap disposed between the anvil and the slide to be detonated. The rifle shown in Fig. 2 includes a slide 6 having guide ribs 6a which engage, in channels 6b formed in the fore-stock, Fig. 5. An extension spring 21 urges the slide towards an anvil 5, and the head 9 of a hammer 10 is normally urged against the rear end of the slide. To cock the hammer, a lever 3 which is pivoted at 24 and has an arm 23 engaging a lug 19 on the slide, is swung downwardly, the slide being moved rearwardly and causing the hammer to pivot against the action of a spring 12. The hammer is latched by the engagement of a shoulder 13 with a shoulder 14 formed on a trigger 16 urged against the hammer by a spring 18. On returning the lever 13 to its raised position, the slide moves forward again due to the spring 21 but not with sufficient force to detonate a cap on the anvil 5. Pulling the trigger releases the hammer, the head of which strikes the rear end of the slide to cause the cap to detonate. Cap feeding means comprises a finger 27 pivoted to the lever arm 23 and urged by a spring 27a against a wall 30 of a magazine M for containing a roll of caps. A spring 30a also bears against the wall 30 and prepares the tape of the cap roll for movement by the finger 27 which travels up the wall when the lever 3 is returned to its raised position. Tc load the magazine, a latch 35 is pressed which allows the magazine to pivot clear of the fore-stock, a roll of caps then being placed on a post 34 and the end of the roll fed between the wall 30 and the spring 30a. The fore-stock consists of longitudinally divided sections which are tapered at their tail portions 40 and held firmly in a corresponding cavity provided in the stock S; a screw 43 engages a nut 42 located in the portions 40. In a modification, Fig. 6, the slide 6a has a lug 19a connected to a link 41a which is connected with a sliding forearm 43a. To cock the hammer 10a, the forearm is pulled rearwardly thus moving the slide to the rear. A further modification, Fig. 7 (not shown), has a slide in the form of a bolt.

Title: Control systems for aircraft gas turbine engines
Inventor: LEWIS WILLIAM GERALD ERIC
IPC: F02K1/16
Filed: 1959-01-22
Abstract: 906,592. Automatic control of gas turbines. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. Jan. 15, 1960 [Jan. 22, 1959], No. 2380/59. Class 38 (4). [Also in Group XXIX] In a control system for a gas turbine jet propulsion engine of the single-spool reheat type having an air intake designed to receive an air flow at supersonic velocity, the thrust is controlled by varying the fuel flow to one of the combustion systems by an open loop control system and the engine rotational speed is maintained constant by controlling the other combustion system by a closed loop control system. As shown, the rotational speed of a jet engine 11 is controlled by varying the reheat fuel supply Qfm from a pump assembly 16 in dependence on an error signal #N from an error box 17. The error box compares a rotational speed signal N with a reference signal NR from a function generator 31 responsive to compressor inlet temperature T 1  as sensed by a thermocouple so that at low compressor inlet temperatures the parameter N/#T is maintained at a limiting value and for higher temperatures the speed N is maintained constant. The reheat system is brought into operation by a signal R, from a control switch 33, which is simultaneously fed to a two-position nozzle actuator 34 to increase the nozzle area to the minimum size for operation with reheat. Finally, the signal R operates a switch 32 so that an actuator 18 is brought into operation to vary the nozzle in accordance with T 1  through a function generator 19. The thrust of the engine is controlled by varying the fuel flow Qfm to a main combustion system from a fuel pump assembly 12 by a pilot's control 13. The effect of the pilot's control is limited by applying a signal #T 4  derived by comparing a signal dependent on combustion chamber temperature T 4  with a reference signal (T 4 )R from a function generator 14 responsive to the compressor inlet temperature T 1 . The fuel assemblies are partially responsive to a signal proportional to compressor inlet pressure P 1  to vary the quantities of fuel delivered to the engine with change in altitude. A function generator 35 fed with a signal proportional to flight Mach number M supplies a signal to control the configuration of the air intake. It is stated that the control signals can be electric, pneumatic or hydraulic. Specification 788,359 is referred to.
